Service HotlineRivet riveting has the advantages of simple process equipment, shock resistance, impact resistance, uniform force transmission, firmness and reliability, etc. The key parts of mining equipment such as skips, cages, dumpers, and mine trucks are all connected by rivet riveting. The quality of rivet riveting directly affects the product quality, working performance and service life of mining equipment. The number of rivets used in mining equipment is huge. Each mining equipment requires one hundred or hundreds of rivets, and they are used in mining equipment. The specifications of the rivets in the equipment are large, and the riveting process of hot riveting is mostly used. The riveting tools required are riveting machines and rivet molds.
Many existing products need to use screws in the production process, especially in the field of nuclear power sluice gates, it is necessary to fill a part of the sluice gate with screws to fix the size and structure. If the fixing effect is not good, then It will lead to more leakage of water gates, waste a lot of water resources, and even cause safety accidents.
The common types of Birminghamwood screws are iron and copper, and the types are divided into round head type and other samples of Birminghamwood screws according to different nail heads. There are two types of slotted screws and cross recessed screws. Generally, the BirminghamBirminghamBirminghamround head screws are made of mild steel and are blue, and the Birminghamflat head screws are polished. The oval head screws are usually plated with cadmium and chrome, and are often used to install hinges, hooks and other hardware accessories. Specifications are determined by rod diameter, length and nail head type. [1]
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.
