Summary of information:We have more than ten years of experience in the production of screw industry, the main products are: stainless steel ex...

In the prior art, there are also automated equipment for riveting and assembling of hardware and handles; however, for the existing automated equipment, how to automatically and efficiently realize rivet feeding is particularly important.

However, Yueluo still feels that there should be room for improvement for the screw improvement and screw that integrates stability, labor, fast and multi-function in the above two cases; for example, No. 556784 screw improvement Although the rod has the function of cutting and collecting chips, when the screw starts to screw into the object such as wood, it is hindered by the hardness of the object's tissue, so the staff still needs to exert considerable force, resulting in the lock. In the solid operation, there is still a lack of difficulty in screwing in operation; another example, new cases such as No. 289410 screw that integrates locking, stability, labor, fast and multi-function, although the rod has the structural function of cutting and chip removal, it is The rod part is screwed into the middle section to the rear section of the object. Since the debris cannot be discharged, the rod part pushes the outer part of the object to the surrounding tissue of the object, so that the object expands outwards and even seriously damages the appearance of the object.

The product structure in the known technology includes a T-shaped bolt with a longitudinal section, and a polygonal nut matched with the bolt. The bolt is divided into two parts: the screw and the screw head. The screw head is placed at one end of the screw to form an integral part. The radial length of the tightening surface of the screw head is greater than the radial length of the screw, and its axial length is less than the axial length of the screw; The solid surface is a polygon, and now a hexagon is commonly used. The periphery of the base of the nut and the screw head has a number of elastic surfaces corresponding to the polygon; the periphery of the axial screw is provided with an external thread matching the internal thread of the nut. In actual use, the fastener of this structure can be tightened by using a conventional screw, such as a wrench. Therefore, its anti-theft performance is poor and it is not suitable for occasions with special requirements.

Most of the existing belts control the length of the belt by fixing the other end of the belt by the buckle, and the period that is often buckled by the buckle will be deformed and damaged after long-term use, and the user may change the position from standing to sitting or after meals. The circumference of the belt can be adjusted, and micro-adjustment is not necessarily possible when adjusting the tightness of the pin buckle type or buckle plate type belt buckle. In order to solve this problem, it is necessary to design a belt that is relatively suitable for the waist of a person.

For the detection of the shear force of the elastic cylindrical pin, the method and the tooling are marked, but the tooling is only a means to be used on the test bench, and the process of embedding the cylindrical pin into the tooling is a more difficult process. Generally, it is used to place the tooling on a plane, a vise, a simple V-shaped, and a simple U-shaped fixture. Originally, the elastic cylindrical pin was detected by hand or pliers to hold the cylindrical pin and align the pin with the outer cylinder of the tooling. Use a hammer to smash the shear holes, and adjust the concentricity of the inner and outer cylinders of the shear holes of the tooling from time to time. The limitations, dangers and difficulties of this assembly method are relatively large, often testing a set of cylindrical pins, which takes a lot of time and is difficult for lesbians to complete.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: wholesale galvanized, wholesale square welding nuts, flat head full hexagon rivet nuts, D6 hollow pins and other products, we can provide you with suitable tightening Firmware Solutions.
