Service HotlineA T-bolt. This kind of bolt includes a bolt shank and a bolt head, and the bolt head adopts a special cylindrical bolt head, which can be suitable for installation and cooperation of various sizes. Although the shape of such a bolt head is greatly improved compared to the square bolt head in the prior art, the cylindrical bolt head is particularly inconvenient to install, and special installation tools must be used for installation. If the manual direct installation method is adopted, since the force area of the finger touching the side of the cylinder is small, it will increase the difficulty of the installation work and needs to be improved.
M4 grounding screw used to fix the grounding wire on household appliances and other equipment, the stud is cylindrical, and the thread is perpendicular to the end (section) surface. However, the screw holes on the equipment all have tapping guide grooves for sinking and guiding due to the manufacturing process requirements. When fixing the ground wire, if the screw is not positioned accurately (the screw is inclined), the screw is pressed down hard, which is easy to cause the screw and the screw. The screw hole bites the teeth, and after biting the teeth, it is easy to cause the screw to loosen or fall off, posing a safety hazard.
One of the steps in the screw production and processing process is to slot the screw head to facilitate the use of a screwdriver when tightening or loosening the screw. Generally, companies use manual sorting, and then use the cutting knife to slot the front end screws through the track, which is inefficient, and because the screws are not fixed, the cutting knife may easily fly out or break the blade during cutting. It is a safety problem, and after cutting, the screw head has rough workmanship and burrs, which is easy to hurt the hand.
1. When the main body is large-scale equipment, accessories need to be installed, such as sight glass, mechanical seal seat, deceleration frame, etc. The stud bolts used at this time, one end is screwed into the main body, and the other end is equipped with nuts after the accessories are installed. , Since the accessories are often disassembled, when the main body and the accessories are directly connected by bolts, the main body threads will be worn or damaged over time, and it is very convenient to use studs to replace them. 2. When the thickness of the connecting body is very large and the bolt length is very long, stud bolts will be used. The purpose of anti-loosening of stud connection In actual work, the external load has vibration, change, high temperature creep of the material, etc., which will reduce the friction force, the positive pressure in the thread pair disappears at a certain moment, and the friction force is zero, thus making the threaded connection loose. , if repeated action, the threaded connection will loosen and fail. Therefore, it is necessary to prevent loosening, otherwise it will affect the normal work and cause accidents.
Yueluo Guangdong Yueluo Hardware Industry Co., Ltd. provides a rivet-oriented positioning riveting tool to overcome the shortcomings of the existing technology. The rivet is placed on the tool, and then placed in the riveting machine together with the product for riveting. In the same way, the scrap rate is reduced and the production efficiency is greatly improved. In order to achieve the above purpose, a rivet guide positioning riveting tool is designed, which includes a riveting positioning block and a riveting lower die, which is characterized in that a riveting positioning block is arranged above the riveting lower die. The riveting positioning block includes a positioning pin and a rivet yielding hole, a through hole is arranged in the center of the riveting positioning block, a rivet hole is arranged on one side of the through hole, and a number of positioning pins are arranged on the riveting positioning block around the through hole. . There are five positioning pins. The riveting lower die includes a countersunk head screw hole, a rivet guide block and a positioning hole. The riveting lower die is a stepped module. The left side of the riveting lower die is provided with a countersunk head screw hole, and the right side of the riveting lower die is provided with a countersunk head screw hole. The guide block is provided with several positioning holes on the riveting lower die located in front of the guide block. There are two positioning holes. The center of the guide block is provided with an escape hole. Compared with the existing technology, Guangdong Yueluo Hardware Industry Co., Ltd. has a rivet-oriented positioning riveting tooling. The rivets are placed on the tooling, and then placed in the riveting machine together with the product for riveting, which solves the problem of manual knock-in. The efficiency is low, and the riveting can be riveted without deviation without manual righting during riveting, so that the quality of the products produced is the same, the scrap rate is reduced, and the production efficiency is greatly improved.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: round head adjustment bolts, half tooth cup head bolts, 304 positioning pins, national standard color metal flat washers and other products, we can provide you with suitable products for you fastener solutions.
