Service Hotlineflange T-bolt, comprising: a T-bolt including a threaded tooth body and a bolt head fixedly connected to the threaded tooth body; a flange gasket with a plurality of clip teeth, the flange gasket passing through the The plurality of clamping teeth are clamped with the bolt head of the T-bolt. The technical solution of the utility model is that when the groove-type embedded parts are embedded vertically or at a certain angle, the plastic flange of the new T-bolt will help the bolt to be pre-positioned at a certain position of the groove. When multiple T-bolts are used for fixing, Only one worker needs to pre-arrange the bolt positions and then lock the nuts, which greatly improves the construction efficiency.
The development of a structure with simple production, reasonable structure and stable feeding is of great significance to the field of riveting automation. Technical realization elements: The purpose of this utility model is to overcome the deficiencies in the prior art, and to provide an automatic feeding device for pressure riveting nuts, which has a compact structure and a reasonable design, and can realize the automatic conveying of the pressure riveting nut on the pressure riveting die. Reduce the use of space, improve work efficiency and save labor costs. According to the technical scheme provided by the utility model: the automatic feeding device for riveting nuts, which is characterized in that: it includes an installation bracket, a connecting frame, a flap bracket, a material pushing cylinder, a material pushing block and a flap; the flap bracket is arranged on the installation Below the bracket and attached to the mounting bracket through the connecting bracket.
In the design of electrical products, in order to avoid the problem of electromagnetic radiation interference, it is necessary to isolate the conduction between metal parts (parts). Especially when the metal parts are locked by metal screws, the conduction between the locked pair of metal parts (parts) is often caused, so it is necessary to try to isolate them. For example, when screws are used to lock the structure iron of the liquid crystal display screen and the iron structure of the foot base, the electromagnetic waves generated by the liquid crystal display screen are easily radiated from the foot base, causing electromagnetic radiation interference.
In general, the size, mechanical properties and working performance requirements of self-tapping screws have the following standards: 1. Self-tapping screw size standard ASME B18.6.3 2010 standard not only introduces the dimensions of slotted and cross-recessed self-tapping screws and metal drive screws, but also includes the mechanical properties and work performance requirements of carbon steel self-tapping screws. The appendix gives instructions for measuring the various dimensions and application guidance on clamping lengths and test apertures. 2. Self-tapping screw performance standards (including mechanical properties and work performance): (1) SAE J933: Introduces the mechanical performance and work performance requirements of carbon steel ordinary self-tapping screws and white-cut self-tapping screws. The requirements for selection of raw materials, heat treatment, depth of carburized layer, surface hardness, and core hardness are further specified. (2) SAE J81: The mechanical properties and working performance of self-extrusion self-tapping screws (self-tapping locking screws) are introduced. (3) SAE J78: The mechanical properties and working properties of self-drilling and self-tapping screws are introduced. (4) IFl-113: The mechanical properties and working properties of self-drilling and self-tapping screws are introduced. (5) ASTM C1513: Introduces the mechanical properties and performance requirements of carbon steel self-tapping screws. For other special types of self-tapping screws, there is no corresponding national or industrial standard, and no data for self-tapping screws made of other metal materials other than carbon steel have been recognized. For technical data on these self-tapping screws, you can check with the manufacturer.
At present, in the production workshop, there is no special tool for removing rivets such as skew, wrong rivets, and multiple rivets. When removing these rivets, workers use homemade rivet removal tools, use a sledgehammer to remove the rivet head, and then use a sharp tool to remove the rivet rod. eject. During the removal operation, sometimes the rivet head will fly out, the speed is high, the danger is extremely high, and the labor intensity is high, which has caused many industrial accidents.
