An inverter comprises an inversion swing link (40) and a cam swing link mechanism in linkage with the inversion swing link (40). The inversion swing link (40) is disposed below a punch base (21) and is L-shaped. A turning angle portion of the inversion swing link (40) is hinged, and a hinging axis is horizontal and is perpendicular to a motion direction of the punch base (21). A cross arm of the inversion swing link (40) is a driving end, and the driving end is connected to the cam swing link mechanism. A vertical arm of the inversion swing link (40) is a driven end, and the driven end corresponds to a striking end surface of a second pre-punching needle of a shear rod. A triple composite electrical contact riveting machine having the inverter comprises a main slider (26), a wire inlet device, a wire shearing mould, a mold base, a cam device for controlling relevant parts of the machine to work in coordination, and an inverter.

Description

一种反向器及具有该反向器的三复合电触头铆钉机 Inverter and three composite electric contact riveting machine with the same

技术领域 Technical field

本发明有关一种铆钉机，特别是指一种冷压焊生产三复合电触头铆钉的且具有新式反向器的铆钉机。背景技术 The invention relates to a riveting machine, in particular to a riveting machine for producing three composite electric contact rivets by cold pressure welding and having a new type of reverser. Background technique

目前，三复合电触头铆钉一般为银触头，有银 (或银合金)的钉帽和钉脚，中间是铜或铜合金或其它导电材料，用于多种电器控制开关上。当这种中间为铜或铜合金的电触头未问世时，电触头铆钉的全部都是银或银合金。新型的三复合铆钉可以节省 50%〜70%的银或银合金材料，降低成本和价格，随着人们对电器控制的需求越来越大，对这种触头的需求也越来越多。 At present, the three composite electric contact rivets are generally silver contacts, with silver (or silver alloy) nail caps and studs, and copper or copper alloy or other conductive materials in the middle for various electrical control switches. When such an electrical contact with a copper or copper alloy is not available, the electrical contact rivets are all silver or silver alloy. The new three-composite rivets can save 50%~70% of silver or silver alloy materials, reducing costs and prices. As people's demand for electrical control increases, so does the demand for such contacts.

目前制作银触头三复合铆钉的设备，由进线装置、剪线模具、冲压装置、使主滑块往复运动的曲轴传动***以及控制机器各相关零部件协调工作的凸轮装置等组成。其进线为三根，即铜线一根，银线两根，由床身一边进铜线和银线，床身另一边进银线，所剪出的线最后送入的成型模具是上下活动的，在曲轴的带动下，主滑块向前运动三次完成：（1)钉脚银铜焊接裁圈；（2)钉头焊接；（3)终镦成铆钉，即曲轴转动三圈为一个生产循环周期，产生一颗复合铆钉。由于成型底模是活动的，对设备制造的精度要求过于严格，且对调机也带来相当的难度。另外，剪线时所剪断的线的断面总是出现一侧粗糙而另一侧光滑，粗糙部位就是毛面，而光滑部位就是光面。现有设备剪钉脚线和剪钉体线是从机床的两侧面向中间剪切，即剪钉脚料与钉体料是方向相反的，造成银铜焊接段即钉脚与钉体材料的结合不理想、不牢靠，出现压焊时断面相互结合是光面对光面，毛面对毛面的情况，如图 1A与图 1B所示，其中 a所示为毛面， b所示为光面。光面对光面的部位会存在空隙，既降低焊接强度，也会给导电带来影响。同时现有技术的钉体裁圈时，是在凸轮作用下，由裁圈顶针经模座上储存模孔内往剪刀杆上的剪刀模孔进行裁圈，由于剪刀杆在顶针方向的后端无依托，长此以往容易影响铆钉设备上剪刀杆零部件的精度，直接影响铆钉成品质量。发明内容 At present, the equipment for manufacturing the silver contact three-composite rivet is composed of a wire feeding device, a wire cutting die, a punching device, a crankshaft transmission system for reciprocating the main slider, and a cam device for controlling the related components of the machine. The incoming line is three, that is, one copper wire and two silver wires. The copper wire and the silver wire are inserted into the bed side, and the silver wire is inserted into the other side of the bed. The cut mold is finally fed into the molding die. Driven by the crankshaft, the main slider moves forward three times: (1) the silver-copper welding cutting ring of the nail foot; (2) the nail head welding; (3) the final rivet, that is, the crankshaft rotates three times into one The production cycle produces a composite rivet. Since the forming bottom mold is active, the precision of the manufacturing of the equipment is too strict, and the adjustment machine is also quite difficult. In addition, the section of the line cut during thread trimming always has a rough side and a smooth side, the rough part is the matte side, and the smooth part is the smooth side. The existing equipment shearing nail line and shearing nail body line are cut from the two sides of the machine tool, that is, the shearing nail material and the nail body material are opposite in direction, resulting in the silver-copper welding section, that is, the nail foot and the nail body material. The combination is not ideal and unreliable. When the pressure welding is performed, the cross-sections are combined with each other. The light faces the smooth surface, and the hair faces the rough surface. As shown in Fig. 1A and Fig. 1B, where a is a rough surface, b is shown. Glossy. There is a gap in the light-facing part, which reduces the welding strength and also affects the conduction. At the same time When the technical nail body is circled, it is under the action of the cam, and the thimble of the cutting ring is cut through the die hole in the storage die hole of the die holder to the scissor bar, and the scissors bar is not supported by the rear end of the thimble direction.
