Service HotlineYueluo 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.
Subway tunnels can be divided into rectangular, arched, circular, and elliptical end face forms according to the section shape of the section tunnel. The rectangular end face can be divided into single-span, double-span and multi-span types. There are two types of circles. The subway tunnel needs to install electromechanical equipment through bolts, insert T-shaped bolts into the preset holes on the shield plate of the subway tunnel, and then cast and fix it. The bolts are smooth and the contact surface is small. The bolts installed in the shield plate are easy to fall off, causing the installed equipment to fall and damage or causing losses to pedestrians or vehicles passing in the tunnel. Therefore, it is necessary to further improve the current bolts.
Stainless steel usually refers to steel that has the ability to resist corrosion by air, water, acid, alkali salt or other medium. Depending on the alloy composition, the focus is on rust resistance and acid resistance. Although some steels are rust-resistant, they are not necessarily acid-resistant, and acid-resistant steels are usually rust-resistant. Austenitic stainless steel is mainly used in the production of fasteners. In people's daily life, the stainless steel often referred to is also austenitic stainless steel. The stainless steel fasteners we use are mainly made of austenitic 302, 304, 316 and low nickel 201 as raw materials.
The shear strength of a metal material refers to the ability of the material to withstand shearing force, which refers to the strength of the external force perpendicular to the material axis and shearing the material. The test is usually to install the cylindrical pin into the specified fixture, and the gap between the supporting part and the loading part is required to be no more than 0.15mm, and then force is applied to test the shear strength of the material.
With the mass production of large-scale equipment, standardization, and the concept of lean production, it has become more and more important to improve the efficiency of the assembly stage. Nowadays, when assembling small equipment, power tools and automatic bolt supply devices are basically popular, but only for M3 and smaller However, large equipment is often fastened with M8 or larger diameter bolts, and it is still in the process of combining manual and air tools. Among them, the pre-installation of the flat and spring washers on the bolts is completely manual operation. When the bolts need to be tightened in large quantities, the shortcomings of low efficiency are particularly obvious, and the flat and spring washers are easy to be scattered when manually assembled, and there are mixed installations of different specifications. Problems such as less installation and missing installation will affect the processing quality.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: anti-loose with toothed pads, locking and non-slip toothed hexagon screws, GB70 cylinder head bolts, GB1015 rivets and other products, we can provide you with suitable products Your fastener solution.
