Abstract
The invention relates to a non-welding connecting mode for a metal connecting sheet and conducting bars. According to the non-welding connecting mode, flat holes (2) are punched at ends of conducting bars (1); an 'n' shape is formed on a metal connecting sheet (3) by bending through a mold; a smooth reference plane (4) is formed at the lower end of the 'n' shape; two corresponding blocking pins (5) which are vertical to the reference plane (4) and correspond to the assembly positions of the flat holes (2) of the conducting bars are bended from two sides of the reference plane (4); and the height of the blocking pins (5) relative to the reference plane (4) is 1.5 times greater than the thickness of the conducting bars (1). During assembling, the metal connecting sheet (3) is fixed in a corresponding groove (7) of a positioning fixture (6) at first, then two conducting bars (1) required to be assembled are positioned by using a middle positioning rib A (8) and two side positioning ribs B (9) of the positioning fixture (6), conducting bar clearances (10) after assembling are ensured, and the two blocking pins (5) of the metal connecting sheet (3) respectively penetrate through the two flat holes (2) and are in clearance fit with the flat holes (2) when the conducting bars (1) are assembled. According to the non-welding connecting mode, an extrusion riveting mode is adopted to replace the original welding mode of the metal connecting sheet and the conducting bars, so that the metal connecting sheet and the conducting bars are reliably connected with each other, can not deform and can be repeatedly used after being disassembled.
Description
Technical field
The present invention relates to end metal connecting sheet and sliver connected mode, particularly a kind of metal connecting sheet and the conducting bar non-welded connected mode of non-frame wiper blade.
Background technology:
The mode that the end metal connecting sheet of present non-frame wiper blade is connected with sliver, mainly be to connect by welding manner, to melt the metal structure of welding region in the welding process, sliver can affect because of temperature distortion the variation of sliver design radian, assemble the in the course of the work overvoltage or under-voltage of adhesive tape on it, finally cause scrape bad.The sliver welding region easily produces welding fragility in the welding process in addition, although can control by tempering, control procedure is affected by temperature fluctuation, produces unavoidably the situation of sealing-off.Secondly, welding process and drawing process need the equipment energising, produce many invalid heat energy, cause energy waste.
Summary of the invention:
The objective of the invention is: a kind of metal connecting sheet and conducting bar non-welded connected mode are provided.In order to solve weak point of the prior art, this connected mode is the flat hole of in advance punching out of sliver end before assembling, on metal connecting sheet, go out " several " font by the mould bending, form a smooth datum level in " several " font lower end, from the datum level both sides and perpendicular to the rigging position in the flat hole of the corresponding sliver of datum level again bending go out the card base of two correspondences, card base is with respect to the thickness of datum level height greater than 1.5 times of slivers.First metal connecting sheet is put into during assembling in the corresponding groove of positioning tool with fixing, then utilize positioning tool middle part positioning bar and both sides positioning bar location to need two slivers of assembling, and guaranteeing sliver gap after the assembling, two card bases of metal connecting sheet and matched in clearance are with it passed respectively in two flat holes during the assembling sliver; Metal connecting sheet datum level after the assembling cooperates with the sliver bottom surface in addition, be used for to guarantee after two slivers assemblings in one plane, thereby can be free to slide in the sliver gap after the assurance adhesive tape is assembled.Press on the end face of sliver by the bared end of frock pressure head with two card bases at last, card base because of stress deformation will with the two flat hole of sliver tight fits, finally fixedly sliver produces looseningly in all directions, also guarantees to press simultaneously rear sliver gap.This kind mode overall process is " cold " processing, has eliminated all adverse effects that cause because of welding, and is energy-saving and cost-reducing in addition.
Formation of the present invention: a kind of metal connecting sheet and conducting bar non-welded connected mode, formed by sliver and metal connecting sheet, it is characterized in that: the flat hole of in advance punching out of sliver end before assembling, on metal connecting sheet, go out " several " font by the mould bending, form a smooth datum level in " several " font lower end, from the both sides of datum level and perpendicular to the rigging position in the flat hole of the corresponding sliver of datum level again bending go out the card base of two correspondences, card base is with respect to the thickness of datum level height greater than 1.5 times of slivers; First metal connecting sheet is put into during assembling in the corresponding groove of positioning tool with fixing, then utilize positioning tool middle part positioning bar A and both sides positioning bar B location to need two slivers of assembling, and guaranteeing sliver gap after the assembling, two card bases of metal connecting sheet and matched in clearance are with it passed respectively in two flat holes during the assembling sliver; The datum level of metal connecting sheet after the assembling cooperates with the sliver bottom surface in addition, is used for guaranteeing after two slivers assemblings in one plane, thereby can be free to slide in the sliver gap after the assurance adhesive tape is assembled; Press on the sliver end face of sliver by the bared end of frock pressure head with two card bases at last, two card bases because of stress deformation will with the flat hole tight fit of two slivers, finally fixedly sliver produces looseningly in all directions, also guarantees to press simultaneously rear sliver gap.
Compared with the prior art, the invention has the advantages that and adopt to squeeze the welding manner that the riveting mode has replaced original metal connecting sheet and sliver that it is more reliable that one metal connecting sheet and sliver are connected by crowded riveting, stopped the possibility of sealing-off after original welding; Its two this connected mode belongs to " cold " processing, has stopped in the welding process sliver and has been heated and causes radian to change; Its three sliver of using after this connected mode is assembled is reusable after dismounting, and the genus of welding is disposable, not reproducible use.This kind mode overall process is " cold " processing, has eliminated all adverse effects that cause because of welding, and is energy-saving and cost-reducing in addition.
