How to Make The Air Duct Corner

Air Duct Corner
When it comes to air duct corner codes, we need to talk about how they are produced, their role in the ducting industry, and what machinery and equipment are needed to produce duct corner codes throughout the production process. Often the most efficient way is to press with the use of dies, and it is also a widely used method. Before that, let’s talk about the press and its classification, etc. Air Duct Corner
A punch is a press. In national production, stamping technology is more and more widely used due to its advantages of saving material and energy, high efficiency, low technical requirements for operators, and inaccessible products made by machining through various die applications. Air Duct Corner
Stamping production is mainly for sheet metal. Through the die, it can make blanking, punching, forming, drawing, finishing, fine punching, shaping, riveting and extrusion parts, etc., which are widely used in various fields. We use switch sockets, cups, cupboards, dishes, computer boxes, and even missile aircraft. There are so many parts that can be produced with a punch through a die. Air Duct Corner
Working Principle
The design principle of the punch press is to convert circular motion into linear motion. The main motor generates power to drive the flywheel. The clutch drives the gear, crankshaft (or eccentric gear), connecting rod, etc., to achieve the linear motion of the slider. The movement of the connecting rod is a circular movement. Air Duct Corner
Between the connecting rod and the sliding block, there needs to be a transition point for circular motion and linear motion. There are roughly two mechanisms in its design, one is ball type, the other is pin type (cylindrical type), through which circular motion Converted into linear motion of the slider. The punch presses the material to plastically deform it to obtain the required shape and precision. Therefore, it must be matched with a set of molds (upper mold and lower mold), the material is placed in between, and the machine applies pressure to deform it, The reaction force caused by the force applied to the material during processing is absorbed by the punch machine body.

Uses And Features
Punching presses are widely used in stamping and forming electronics, communications, computers, household appliances, furniture, vehicles, hardware parts (automobiles, motorcycles, bicycles).
High-rigidity, high-precision frame, welded by steel plate, and after heat treatment, eliminates the internal stress of the fuselage technetium so that the equipment can work stably for a long time without deformation. The structural parts have a uniform load and balanced rigidity. Air Duct Corner
Stable high precision, the main parts of the equipment, such as the crankshaft, gears, and transmission shafts, are hardened and heat-treated and have high wear resistance during grinding. The long-term performance is stable, and the requirements for high precision and stability are ensured. Air Duct Corner
Reliable and safe operation performance, the reason for the convenient operation and accurate positioning is that different from the traditional brake, the clutch/brake combination device has high sensitivity, plus the double solenoid control valve and overload protection device commonly used in international high-end equipment. Ensure the accuracy and safety of the high-speed movement and stop of the punch slide.
Production automation, the punch can be equipped with a corresponding automatic feeding device, with feeding error detection, pre-cutting, and pre-cutting devices, which can fully realize automatic production with low cost and high efficiency. Air Duct Corner
Slider adjustment mechanism, the sliding speed adjustment is divided into manual adjustment and electric adjustment, which is convenient, reliable, safe, and fast, and the accuracy can reach 0.1mm. Air Duct Corner
Classification of Punches
According to the different classifications of driving force, the driving force of the slider can be divided into three types: mechanical, hydraulic, and pneumatic. Therefore, punch presses are divided into mechanical punches, hydraulic punches, and pneumatic punches according to the driving force used. Air Duct Corner
For ordinary sheet metal stamping, most of them use mechanical punching machines. Depending on the liquid used, hydraulic presses include hydraulic presses and hydraulic presses. The majority of hydraulic presses are hydraulic presses, while hydraulic presses are mostly used for giant machinery or special machinery. Pneumatic punching presses are driven by gas produced by air pumps, which are much faster than the other two punching presses, and are often used with automatic feeding production equipment. Air Duct Corner
There are single-action, double-action, and three-action presses according to the movement of the slider. The single-action press with one slider is the only one that is used most today. The double-action and three-action presses are mainly used in the extension of automobile bodies and large-scale machining parts. The number of processing is very small.
The largest classification method is classified according to the slider drive mechanism, and the following examples are given one by one. Air Duct Corner
1. Crankshaft Punch
Presses that use crankshaft mechanisms are called crankshaft presses, crankshaft presses, and most of the mechanical presses
Use this institution. The reason for using the crankshaft mechanism most is that it is easy to manufacture, can accurately determine the lower end position of the stroke, and the movable curve of the slider is basically practical for various processing. Therefore, this type of stamping is practical for punching, bending, stretching, hot forging, warm forging, cold forging, and almost all other punching processes.
2. No Crankshaft Punch
No crankshaft type punch is also called eccentric gear type punch, eccentric gear type punch. The function of the crankshaft punch and the eccentric gear punch is as shown in Table 2. The eccentric gear punch is better than the crankshaft in terms of shaft rigidity, lubrication, appearance, and maintenance. The disadvantage is that the price is higher. When the stroke is long, the eccentric gear punch is more advantageous, and when the stroke of the special punching machine is short, the crankshaft punch is better. Therefore, small machines and high-speed punching punches are also the fields of crankshaft punching.
3. Toggle Punch
Those who use the toggle mechanism on the slider drive are called toggle punches. This punch has a unique slider activity curve that the speed of the slider near the bottom dead center becomes extremely slow (as measured by a crankshaft punch). Moreover, the position of the bottom dead center of the stroke is correctly determined. Therefore, this type of punch is suitable for compression processing such as embossing and finishing and is most commonly used in cold forging today.
4. Friction Punch
A punch that uses friction transmission and a screw mechanism on the track drive is called a friction punch. This type of punch is most suitable for forging and crushing operations. It can also be used for bending, forming, stretching, etc. It has versatile functions. Because of its low price, it was widely used before the war. Due to the inability to determine the lower end position of the stroke, poor processing accuracy, slow production speed, overload when the control operation is wrong, and the need for skilled technology in use, these shortcomings are gradually being eliminated.
5. Spiral Punch
Those who use the screw mechanism on the slider drive mechanism are called screw punches (or screw punches).
6. Rack Punch
The use of a rack and pinion mechanism on the slider drive mechanism is called a rack punch. Spiral punches and rack punches have almost the same characteristics, and their characteristics are almost the same as those of hydraulic punches. In the past, it was used for pressing into bushings, crumbs, and other items, such as extrusion, oil extraction, bundling, and the extrusion of bullet casings (hot room squeezing processing), but now it has been replaced by hydraulic presses, unless extremely special No longer used outside of the circumstances.
7. Connecting Rod Punch
A punch that uses various linkage mechanisms on the slider drive mechanism is called a linkage punch. The purpose of using the linkage mechanism is to keep the drawing speed within the limit while reducing the processing cycle during the drawing process and use the reduction of the speed change of the drawing process to speed up the approach stroke and the distance from the top dead center to the processing start point.
The speed of the return stroke from bottom dead center to top dead center makes it have a shorter cycle than a crankshaft punching machine to improve productivity. This type of punch has been used for deep extension of cylindrical containers since ancient times, and the bed surface is narrow, while it is used for the processing of automobile body panels and the bed surface is relatively wide.
8. Cam Punch
A punch that uses a cam mechanism on the slider drive mechanism is called a cam punch. The feature of this punch is a well-made cam shape in order to easily obtain the desired sliding curve. However, due to the nature of the cam mechanism, it is difficult to convey greater strength, so the punching capacity is very small.
Application of Punch in Air Duct Industry
Common-plate flange air duct corner code also called common-plate flange duct hook code, or common-plate flange duct hook code, is the plating that fixes and connects during the production process of common-plate flange duct The corner fittings made of zinc plate have a 90-degree right-angle shape with an ellipse with a length of 8mm and a width of 10mm at the corners. They are used to connect air ducts with screws. They are necessary accessories for the production of common-plate flange ducts. .
The corner code of the air duct is used as an accessory at the interface of the ventilation pipe, and it is pressed by a thicker specification galvanized sheet, which can play a stable role. The surface has strong oxidation resistance, wear resistance, and corrosion resistance.
The production process of the air duct corner was relatively cumbersome in the early days, requiring two steps of pressing and punching to be completed. Now the developed air duct corner code one-time forming mold can directly produce complete and qualified air duct angle codes, which is particularly convenient.
Duct Corner Mould
Because of the high frequency used in the work of the one-time forming air duct corner code mold, it is necessary to use steel with excellent materials for processing and manufacturing during the production process. After the good steel is processed by various precision machines, the workpiece and material parts are heat-treated after being made into molds as required, which improves the hardness of the corner code mold. At present, the commonly used one-time forming corner code mold can process the corner code of galvanized sheet material with a thickness of 1.5mm.
At present, in the production process of the air duct angle code, the one-time forming angle code mold can be processed with a mechanical punching machine, and at the same time, it can also be used with a pneumatic punching machine for the production and processing of the air duct angle code. The production method of mechanical punching presses has a higher manual level, so it requires full-process workers to operate, and the efficiency is lower.
The speed of producing corner codes is relatively slow, which is related to the worker’s operational proficiency. Due to its own high-speed characteristics, a pneumatic punching machine can realize the production of an automatic duct angle code with an automatic feeding device and coil rack. During this period, workers are not required to maintain and operate the whole process, which is very efficient. However, the disadvantage is that the price is much more expensive and it is more suitable for large quantities. The processing plant is configured.
Based on the important role of the air duct angle code in the air duct industry, basically, every processing plant and construction site needs to use the air duct angle code, so the angle code punching machine is particularly widely used. Accompanied by a large number of applications, our HARSLE company provides high-quality mechanical punches for use with corner molds. At the same time, we can also customize high-efficiency duct angle code production lines with different speeds for powerful manufacturers. Welcome to consult.
