How Metal Stamping Processes Prevent Hidden Dangers

　　Metal Stamping processing is dangerous, but it is not really dangerous. It complies with the stamping system and operates properly. Stamping is still very safe. During the Metal Stamping process, for safety reasons, pay attention to the adjustment screw of the slider, and do not let it extend too long. In the Metal Stamping process, in order to prevent the mold from moving, it is possible to put a layer of paper on the reinforcement, and the Stamping Mould is a dangerous situation. For the safety of metal stamping parts processing, disassemble the mold and wait until the machine is completely stopped. Metal Stamping processing, if you need to adjust and install the mold, you must first turn off the power in action, although it can be carried out without turning off the power, the risk index will be greatly increased, so in order to be safe, the power must be completely shut down completely. Operate after stopping operation. In Metal Stamping processing, the presence of fastening screws will guarantee the safety of metal stamping parts processing. In order to make this protection not a hidden danger, it is necessary to tighten the fastening screws frequently to ensure that the fastening screws can To the security features.

　　Frequently Asked Questions about Metal Stamping Stretch Parts Production

　　1. The shape and size of the tensile parts do not conform to the shape and size of the metal stamping tensile parts. The main reason is that the bullets and the positioning are not allowed. In addition to taking measures to reduce the rebound, the reliability of the blank positioning should be improved.

　　2. Tensile surface scratches Metal stamping tensile parts surface strain is due to improper material selection, low heat treatment hardness, poor finish, concave corner wear, poor curved surface quality, excessive material thickness, process options Unreasonable, lack of lubrication and other reasons.

　　3. Tensile bending crack

　　(1) When the angle between the bending line and the embossing direction of the sheet material does not conform to the specified layout, the bending line should be perpendicular to the embossing direction when unidirectional V-shaped bending; when bending in both directions, the bending line and the embossing direction are preferably 45. degree.

　　(2) The plastic material of the tensile member is poor.

　　(3) The bending radius is too small, and the pickling quality is poor.

　　(4) Insufficient lubrication - high friction.

　　(5) The radius of the fillet of the convex and concave mold is worn or the gap is too small - the feed resistance is increased.

　　(6) The quality of the sheared blank and the punched section are poor – burrs and cracks.

　　(7) The material thickness is seriously out of tolerance - difficulty in feeding

　　Solutions to problems with stretched parts:

　　1. The shape of the stretch forming process should be as simple and symmetrical as possible, and deep drawing as much as possible;

　　2. Stamping Bending Forming Parts that require multiple stretching, in response to the necessary appearance quality, respond to the presence of traces that can occur during the stretching process inside and outside the surface;

　　3. Under the premise of ensuring the installation requirements, the sidewall of the tensile member should have a certain inclination;

　　4. The spacing between the edge of the hole or the side of the flange on the flange should be appropriate;

　　5. The bottom and the wall of the tensile member, the flange and the wall, and the corners of the rectangular member should be suitable;

　　6. The scale of the tensile members is not indicated together.
