Inlaid nut of self-punching type

Abstract

The invention discloses an inlaid nut of self-punching type, comprising a nut body. The nut body is arranged to be a reverse ladderlike body with a wide top and a narrow bottom, a slot is arranged between the upper layer and the lower layer of the nut body, and the nut body is also provided with a longitudinal through hole. The invention has the advantages that: (1) simple operation process and greatly improved working efficiency; (2) convenience of use and high contraposition accuracy; (3) firmer fixation; (4) effective protection of sheet metal pieces after surface treatment and favorable improvement of the whole performance of the product; (5) favorable environmental protection; and (6) electricity saving and effectively reduced production cost.

Description

technical field [0001] The present invention relates to the technical field of fasteners, more specifically to the technical field of nuts embedded in fasteners. Background technique [0002] If it is necessary to fix other parts on the thinner sheet metal, or to fix the thinner sheet metal itself, due to its thin wall, it is impossible to tap threads on it or fix it by bolts. At present, The usual way is to first open a through hole on the sheet metal, and then weld a nut at the opened through hole, so as to fix other parts on the sheet metal by bolts or fix itself. The disadvantages are: 1. The process is more complicated, and the through hole needs to be opened first during operation, and then the weld nut can be welded on the through hole only after the hole of the weld nut is aligned with the through hole, and the work efficiency is low; 2. It is inconvenient to use, if the weld nut is If the hole is not aligned with the opened hole, it will be difficult to assemble or...

Problems solved by technology

[0002] If it is necessary to fix other parts on the thinner sheet metal, or to fix the thinner sheet metal itself, due to its thin wall, it is impossible to tap threads on it or fix it by bolts. At present, The usual way is to first open a through hole on the sheet metal, and then weld a nut at the opened through hole, so as to fix other parts on the sheet metal by bolts or fix itself. The disadvantages are: 1. The process is more complicated, and the through hole needs to be opened first during operation, and then the weld nut can be welded on the through hole only after the hole of the weld nut is aligned with the through hole, and the work efficiency is low; 2. It is inconvenient to use, if the weld nut is If the hole is not aligned with the opened hole, it will be difficult to assemble or cannot be used, which will greatly affect the subsequent work or the workpiece will be scrapped; 3. The welding is not firm, because the welding nut is welded to the sheet metal panel through the four corner points on it. If there is an error, there will be a phenomenon that the welding cannot be firm; 4. It will affect the use of the product. Due to the need for welding operations, welding slag will easily be generated. If the welding slag falls on the wire opening of the welding nut, it will damage the welding nut. During the same welding operation, the high temperature at the solder joint will also burn the surface-treated sheet metal parts and welding nuts; 5. It is not conducive to environmental protection. Good health, and it will also affect the production environment of the entire production workshop, which does not meet the current people's requirements for environmental protection; 6. The energy consumption during production is high. Since the welding machine is a high-power electrical equipment, frequent welding operations will It needs to consume a lot of electric energy, and at the same time, in order to cooperate with the movement and alignment of the welding nut, various mechanical parts also need to consume a certain amount of electric energy, which also increases the production cost
