Service HotlineIn view of the above-mentioned deficiencies of the prior art, Guangdong Yueluo Hardware Industry Co., Ltd. aims to provide a stamping die and stamping parts for punching rivets, and a positioning floating pin is added on the die to solve the problem of the prior art. The placement of the rivets during punching is inaccurate, resulting in the problem of poor quality. In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. has adopted the following technical solutions: a stamping die for punching rivets, including a lower die base, a lower die plate and a lower die insert block; the lower die plate and the lower die insert The block is arranged on the lower die base, and the lower die entry block passes through the lower die plate and protrudes to one side of the lower die plate, and a positioning floating pin is arranged in the lower die entry block, An elastic member for supporting the positioning lift pin is arranged in the lower die holder. The punching die for punching rivets further includes an upper die base, an upper clamping plate and a riveting punch, the upper clamping plate and the riveting punch are arranged on the upper die base, and the riveting punch passes through the upper die base. The upper splint extends to one side of the upper splint. In the punching die for punching rivets, the positioning and lifting pins are provided with protrusions for guiding the rivets. In the punching die for punching rivets, the lower die base is provided with a set screw for fixing the elastic member. In the punching die for punching rivets, the stop screw is installed on the bottom surface of the lower die base. In the punching die for punching rivets, a lower backing plate is arranged between the lower die base and the lower template. In the punching die for punching rivets, the elastic member is a spring. A stamping part is provided with rivets, and the rivets are stamped and fixed by the above-mentioned stamping die. In the stamping part, the stamping part is a back plate. Compared with prior art, the stamping die and the stamping part that Guangdong Yueluo Hardware Industry Co., Ltd. provides for punching rivets, have adopted and set up positioning floating pins in the lower die block, in the lower die holder An elastic piece for supporting the positioning lift pin is provided. Before punching, the positioning lift pin is held up by the elastic piece, so that the positioning lift pin extends out of the lower die into the block, and the rivet is placed on the positioning lift pin during stamping. On the pin, the rivet is guided by the positioning lift pin. During the stamping process, the rivet falls closely with the positioning lift pin to prevent the rivet from being skewed. When the stamping die is completely closed, the stamping is completed, which improves the quality of the stamped product and greatly improves the production efficiency.
Building aluminum alloy formwork is a new type of building formwork, which conforms to the four sections and one environmental protection policy. It is economical, fast, high-quality and environmentally friendly. Its application is of great significance to building energy conservation and environmental protection. The aluminum template is filled with aluminum template pins. However, the pins in the prior art have low connection strength during use, which is likely to cause the hole to be repaired weakly.
The capped nut can prevent the bolt connection from directly contacting with the outside world, which is corroded and makes it difficult to disassemble later. Nuts with caps in the prior art are mostly of one-piece structure, and the surface is not treated with anti-oxidation, which is easy to be corroded. In addition to the protective effect, the fastening method is the same as that of ordinary nuts, so it is easy to loosen when subjected to severe vibration. .
Guangdong Yueluo Hardware Industry Co., Ltd. provides a kind of rivet, parts and parts are riveted by the rivet, the part has a fixed plate and a fixed plate, and the part is located between the fixed plate and the fixed plate, The rivet includes a nail head, a nail post and a nail post which are connected in sequence, the diameter of the nail post is larger than the diameter of the nail post, the nail head is matched with the outer end surface of the fixing plate, and the length of the nail post is It is greater than the sum of the riveting length of the fixing plate and the riveting length of the part. The rivet can control the distance between the parts, so that the relative rotation of the two parts is more smooth and easy to operate.
Fan rivets are specially designed for manual installation. They can be pulled in through the holes of the panel or the bottom frame. They are made of elastomer material with good toughness and can be installed quickly even in interference assembly. The design is clever and has elastic function. It is not easy to slide out after being pulled in with the corresponding aperture. The fan rivets are mainly used in the fixing of electronic computer case fans, heat sinks and chips, with anti-vibration and noise reduction.
