Service HotlineIn some embodiments, the rivet fixing mechanism includes a left moving block, a right moving block, a return spring and a bracket, wherein both the left moving block and the right moving block are movably mounted on the bracket, and the left moving block and the right moving block are connected by a return spring, The insertion mouth can extend between the left moving block and the right moving block, and withstand the left moving block and the right moving block. The left moving block is provided with a left half hole, and the right moving block is provided with a right half hole matching the left half hole. hole. Therefore, when the insertion nozzle is not inserted, the left moving block and the right moving block can be combined together by the return spring, so that the left half hole and the right half hole are combined into one hole to fix and position the rivet, and when the insertion nozzle is inserted When , the left moving block and the right moving block will be pushed up by the insertion mouth to separate the left half hole and the right half hole, so that the rivet is no longer fixed and can be inserted with the movement of the insertion mouth.
lead screw nut is provided with a through hole in the center for the screw rod to pass through, the surface of the through hole is provided with a screw thread engaged with the thread on the outer surface of the screw rod, and the surface of the through hole of the lead screw nut is provided with a thread along the surface of the through hole. The oil storage groove in the axial direction, the depth of the oil storage groove is greater than the depth of the thread.
In 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.
kind of nut provided by Yueluo, the nut is in the shape of a casing and is provided with a threaded section. The two ends of the threaded section are respectively provided with two convex blocks, and the convex block at the front end of the screw-in direction reaches the hole core. The distance is greater than the nominal size of the thread segment, and the distance from the rear end projection in the screwing direction to the hole core is smaller than the nominal size of the thread segment.
The screw refers to the screw (foreign name: Screw), which is a tool that uses the physical and mathematical principles of the oblique circular rotation of the object and the frictional force to gradually fasten the utensils and parts. Screw installation names are divided into: machine screws, self-tapping screws, drill-tail screws, wallboard screws, fiberboard screws, wood screws, hexagonal wood screws, non-prolapse screws, combination screws, miniature screws, furniture screws, electronic screws, chain belt screws .
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: external hexagon combination screws, cross flat head machine bolts, flat washer external hexagon screws, gun pull cap guns and other products, we can provide you with suitable products for you fastener solutions.
