Abstract
The utility model discloses a self-punching type embedded nut which comprises a nut body, wherein the nut body is arranged in a reverse-step layered shape with wide top and narrow bottom, a gripping groove is arranged between an upper and a lower layers, and a longitudinal through hole is arranged on the nut body. The self-punching type embedded nut has the advantages that firstly, the operation process is simple, and the working efficiency is greatly enhanced; secondly, the use is convenient, and the para-position accuracy is high; thirdly, the fixation becomes more firm; fourthly, sheet-metal pieces with processed surfaces can be effectively protected, thereby being favorable to enhancing the overall property of products; fifthly, the self-punching type embedded nut is beneficial to environment protection; sixthly, the electric energy is saved, and the production cost is effectively reduced.
Description
Technical field
The utility model relates to the technical field of fastening piece, more particularly relates to the technical field of embedding nut in the fastening piece.
Background technique
If need on thin metal sheet, fix other parts, or will fix than thin metal sheet self, because the wall of himself is thinner, make and to attack the system screw thread in the above, or fix by bolt, at present, common way is to open earlier a through hole on metal sheet, weld a nut in the through hole of being opened again, thereby fix other parts or himself is fixed on metal sheet by bolt, its deficiency is: 1, technology is complicated, need open the hole earlier during operation, again with the hole of welded nut with after this through hole aligns, welded nut could be welded on this through hole, working efficiency is lower; 2, use inconveniently,, cause and assemble difficulty and maybe can't use, will influence postorder work greatly or workpiece is scrapped if the hole of welded nut do not align with opening hole; 3, not prison welding is solid, because welded nut is to weld by four angle points on it and metal sheet panel, mistake is arranged slightly, will occur can't firm welding phenomenon; 4, influence the use of product,, will have welding slag to produce easily owing to need carry out welding operation, if welding slag drops on the silk mouth of welded nut, will damage welded nut, during same welding operation, the high temperature at solder joint place also can scaling loss pass through surface-treated metal sheet and welded nut; 5, be unfavorable for environmental protection, when carrying out welding operation, spark and electric arc that welding produces not only can influence health of operators, and can influence the production environment in whole production workshop, and incompatible people at present are to environmental protection requirement; Energy consumption is higher when 6, producing, because welding machine is a kind of powerful consumer, frequent welding operation just need consume a large amount of electric energy, and each mechanical part is in order to cooperate moving and alignment of welded nut simultaneously, also need to consume certain electric energy, so also just increased cost of production.
The model utility content
The purpose of this utility model is exactly in order to solve above-mentioned deficiency, provide a kind of operating procedure simple, high working efficiency, easy to use, need not the hole, need not welding, help environmental protection and energy-conservation, and to also not producing a kind of from the punching type embedding nut of any influence through surface-treated metal sheet.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
A kind of it is made of nut body from the punching type embedding nut, and described nut body setting is inverted steps stratiform wide at the top and narrow at the bottom, offers draw-in groove between this is two-layer up and down, also offers longitudinal hole on the described nut body.
Through hole on the described nut body is a tapped hole.
Described nut body is T-shaped.
Draw-in groove on the described nut body is and is symmetrical arranged.
Described nut body integral body is tabular.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: 1, operating procedure is simple, working efficiency has obtained improving greatly, owing to saved independent opening step, directly by an end narrower on the nut body under the effect of stamping press, once property is gone out the hole that adapts with nut body narrow end size on metal sheet, simultaneously, by the draw-in groove on the nut body with himself fixedly holding on metal sheet, thereby reached punching and the fixing disposable purpose of finishing simultaneously; 2, easy to use, aligning accuracy is high owing to do not need perforate in advance, not needing just can not influence postorder work with the alignment of two holes on plate and the nut yet yet; Owing to have only one procedure, so the aligning accuracy height; 3, owing to do not need welding procedure, but by cold stamping with the nut body punching press after holding on metal sheet, both area of contact are big, fixingly will become more firm; 4, same owing to do not need welding procedure, just can not produce welding slag, the phenomenon that present welding slag damages the silk mouth just can not appear yet, do not influence use, equally can not produce high temperature at the solder joint place yet, thereby protected effectively and passed through surface-treated metal sheet, helped the raising of product overall performance; 5, help environmental protection, the utility model is to fix by the cold-stamped form, need not welding, just do not have the generation of welding spark, thereby effectively guaranteed the healthy of staff, also protected the production environment in whole production workshop simultaneously, adapted to present people environmental protection requirement; 6, energy-conservation, owing to do not need to use this powerful consumer of welding machine, also reduced each mechanical part simultaneously for moving that attaching nut aligns, thereby saved electric energy, effectively reduce cost of production.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is fixed on structural representation on the metal sheet for the utility model.
Embodiment
By illustrated in figures 1 and 2, a kind of from the punching type embedding nut, it is made of nut body 1, this nut body 1 is whole T-shaped tabular, offer longitudinal hole 2 on the described nut body 1, this through hole 2 can be a tapped hole, described nut body 1 is provided with and is inverted steps stratiform wide at the top and narrow at the bottom, between this is two-layer up and down, offer draw-in groove 3, this draw-in groove 3 is and is oppositely arranged, described nut body 1 can be made into hexahedron, shape such as octahedron or cylindrical body, described draw-in groove 3 can only be provided with a pair of, and how right also can be arranged to, if nut body 1 is a cylindrical shape, then draw-in groove 3 is provided with draw-in groove ringwise, and Fig. 2 is that nut body 1 is fixed on the structural representation on the metal sheet 4.In a word, the utility model can be made into difformity and different size specifications, to adapt to different clients' needs.
Claims (5)
