A metalworking process widely used in the manufacturing industry is called punching. With the unique advantages of punching, punch mold suppliers are helping the manufacturing industry to ease their work with their products. Punching can be performed by hand or by machine.
Punching is the most cost-effective and quick process for creating holes in metals workpieces. It can also create holes in a variety of shapes. By simply using a die in a shape, the manufacturing industry can create the shape required. Punching is done on metal workpieces, can also be used in plastic workpieces.
Punching machines in the manufacturing industry are widely used in the production of hardware parts such as computers, households, electronics, transportation, furniture, automobiles, and more. The characteristics of punching include:
The major parts of the components such as gear, crankshaft, transmission shaft, and more are hardened and heat-treated after grinding and have high resistance. Making sure the needs of high precision and stability are met, the long-term performance is stable.
The reliability, safety, and accuracy of high-speed movement stops of the punch sliders are ensured because the combined devices that differ from traditional brake have high sensitivity, overload protection device, and are combined with the double electromagnetic control valve.
The punch can be used in combination with the automatic feeding device, which includes feeding mistake detection, pre-cutting, and pre-breaking devices, allowing for completely automated production at a low cost and great efficiency.
The quick change is divided into manual and electric adjustments, all of which are convenient, dependable, safe, and quick, with an accuracy of 0.1mm.
It has the advantages of minimal noise, low energy consumption, and no pollution with advanced technology and design principles.
Punching is done to create one or more holes in a metal workpiece. Their mechanism of creating holes is simple and effective. The workpiece is aligned with a punching tool that is made of tungsten carbide or with the same metal with a great level of strength and dies.
When the punching tool is in place, it is driven down and into the workpiece, removing a piece of metal in the same form as the die. The workpiece will have a round hole if a circular die is used. The workpiece will have a triangular hole if a triangular die was used. Punching always results in holes that are the same form as the die.
Punching was done from hand only in the previous times. Today also it can be done by hand, but the technology has developed now, and punching is also performed by using machines. The machine uses hydraulic pressure to push the punching tool onto and through the workpiece. A die block in the required hole is beneath the punching press. The punching press leaves a hole in the die’s shape as it pushes through the workpiece.
