Service HotlineThe main technical problem to be solved by Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a rivet that can choose the breaking point, which can not only solve the bad effect caused by random shearing, but also can keep the mandrel in the hole to increase the strength after riveting, and also When the same type of rivet is riveted with different riveting thickness, changing the mandrel breakpoint can always make the mandrel breakpoint break at the required place, improve the tensile and shear strength of the rivet, increase the riveting quality of the product, and prolong the service life of the rivet.
With the popularization of electrical equipment, the door cover that integrates the panel, the controller, the sealing and waterproof function and the appearance decoration has gradually been required for equipment matching. The head directly affects the appearance, and for kitchen equipment such as dishwashers, the fixing screws of the door cover are easily rusted in direct contact with the washing water, which urgently needs a door cover structure that is easy to disassemble but does not affect the appearance.
An elastic cylindrical pin loading and unloading tool, comprising a rectangular base on which a hollow cylindrical tooling station is arranged for fixing a tooling and installing a cylindrical pin on the tooling for shear force testing, the The tooling includes an outer cylinder and an inner cylinder that are assembled together, the outer cylinder and the inner cylinder are in clearance fit, and the base is further provided with a counterbore for taking out the inner cylinder after the tooling test is completed.
There are many types of rivets, including dome head, flat head, blind rivet and so on. When riveting parts, they will have uneven force and affect the quality of riveting. Some rivet caps are too thin to easily affect the quality of riveting. Some rivets have poor tightness of riveted parts when riveting. Therefore, both the structure of the rivet and the tightness of the riveting need to be considered, so as to enhance the quality of the rivet fastening.
There are two typical pin shearing fixture tooling, among which the traditional fixture shown in Fig. 1 is more complicated and consists of fixture, spacer, washer and shearing block guide post, hardened bushing, shearing block and so on. The cylindrical pin is installed in the hardened bushing, and the axial load is applied through the shear block to complete the shear test. The fixture is complicated in manufacture and has many consumables, because the size of the hardened bushing is similar to that of the cylindrical pin. , and to keep the notch of the cylindrical pin upward, it is difficult to install before the test, and the broken cylindrical pin after the test remains in the hardened bushing and is difficult to remove.
