Most of the world's steel is made into finished products by stamping. The body, chassis, fuel tank and radiator sheet of automobiles, steam ladle of boilers, the shell of containers, and silicon steel sheet of the iron core of motors and electric appliances are all stamping processes. There are also a large number of stamping parts in products such as instruments, household appliances, bicycles, office machinery and living utensils.

Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can make workpieces with reinforcement, ribs, undulations, or flanges that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision dies, the accuracy of workpieces can reach a micron level, and with high repetition accuracy and consistent specifications, holes nests and tabs can be stamped out.

Metal Stamping Parts Common Problems Treatment

1. Bonding, scratch: due to material and convex die or concave die friction and in the surface of the parts or mold appear bad;

2. Burr: mainly occurs in the shear die and drop die, the gap between the edges is large or small will produce a burr;

3. Line offset: when the part is formed, the first part in contact with the mold is squeezed and formed a line;

4. Convex and concave: uncoiling line with foreign objects (iron chips, rubber, dust) mixed in to cause convex and concave;

5. Zigzag: due to uneven stress, poor matching of the stretching bar or poor control of the press slider, etc., causing zigzag and strain on the r-angle part of the part or the embossed part;

6. Wrinkles: due to poor adjustment of the press slider, low precision of the press, improper adjustment of the air cushion pressure, large punch or r parts caused by the edge or r parts wrinkles.

7. Other specific problems: In daily production, we may encounter situations where the punch size is large or small (possibly exceeding the specification) and the size of the die differs greatly from that of the convex die, taking into account the design size of the forming convex and concave dies, processing accuracy and punching clearance, etc.

When punching holes with a concave die, the standard of hole diameter is based on the diameter of the convex die. For example, if the hole diameter is ф10mm, the diameter of the punching die is 10mm, and the die clearance is adjusted by the size change of the punching die. 2. The selection of the punching die When punching different materials with the punching die, the different materials of the punching die will affect the selection of the die clearance. In order to ensure the quality of the hole section, dimensional accuracy, and to improve the service life of the punching die and the die, the die clearance is usually selected in consideration of the deviation in the production of the die and the wear and tear in use, and usually, only an appropriate range can be selected as a reasonable clearance.

What is The Role of A Bushing?

The use of bushings is more flexible and it can play a lot of roles. In general, bushings are a type of component that protects the equipment. The use of bushings can reduce the wear, vibration and noise of the equipment, and have the effect of corrosion prevention. The use of bushings can also facilitate the maintenance of machinery and equipment, and simplify the structure of equipment and the manufacturing process.

The role played by the bushing in the actual work and its application environment and purpose have a lot to do with it. In valve applications, bushings are installed in the valve cover and sleeve of the valve stem to reduce valve leakage and achieve sealing. In bearing applications, bushings are used to reduce wear between the bearing and the shaft seat and to avoid increased clearance between the shaft and the bore.

Why Do Punches Break Easily?

When using stamping dies for production, the phenomenon of punch breakage will occur. The following will introduce you to the common causes of punch breakage.

1. The closing height is too low and the punch is cut into the cutter part too long.

Solution: Adjust the closing height so that the punch cutter is of the right length.

2. Improper positioning of the material causes the punching tungsten steel punch to cut a single side and fracture due to uneven force.

Solution: Adjust the positioning or feeding device.

3. The lower die waste blocks the cutter's mouth, causing the punch to break.

Solution: Re-drill the big drop hole to make the drop material smooth.

4. The fixed part of the punch (clamping plate) and the guiding part (playing plate) are offset.

Solution: Repair or re-linear cut into the block to make the punch head go up and down smoothly.

5. The punching plate is not well oriented, causing the punch to be stressed on one side.

Solution: Repair the gap in the punching plate.

6. The punch cutter is too short, and the punching plate is dry.

Solution: Change the punch again and increase the length of the cutter part.

7. The punch is not fixed well and moves up and down.

Solution: Re-fix the punch so that it cannot move up and down.
