Abstract

The utility model relates to a metal wire cold pressure welding machine, which belongs to a device with little energy consumption for quickly producing high quality metal wire welding joints. One side of the utility model is provided with a handle which is used for operating a cam. A lever arm which is hinged at the end part of the cam is rotated by the cam through two push blocks. The upper end of a lever causes the pressure to be transferred to a mold through a cover plate, a pressing block, a pressure spring, and a knock pin. A hole which is arranged between two half blocks of the mold is matched with the phase path of a processing wire, and therefore, the wire which is clamped between the two half blocks is obtained with strong extrusion force to achieve an intermolecular distance to form reliable connection. The clamping of the wire is realized by that a handwheel is rotated, clamping sand is moved inwards, a clamping head is opened, the wire is inserted, the handwheel is loosened, and the clamping head is closed.

Description

Metal wire rod cold welding is met sb. at the airport

The utility model relates to a kind of metal wire rod cold welding meets sb. at the airport, and belongs to the Cold welding equipment of metal wire rod.

Produce the producer of this equipment at present, production as copper cash, all adopt butt welding, wind weldering, utilize big electric current to produce the method for high temperature heating, the fusing of copper cash joint is connected, its shortcoming is, the easy oxidation of copper cash joint part, metallographic structure is loose, has increased the resistance value of copper cash, reduce the tensile strength of copper cash, directly influenced the usability of copper cash

The purpose of this utility model is: a kind of equipment that any metal wire rod is connected under the normal temperature state fast, securely is provided, promptly uses the technology of Cold welding, make the copper cash after the welding have superior quality, at internal consumption welding interval energy seldom.This equipment has volume advantage little, in light weight, easy to use.

The technical solution of the utility model is: metal wire rod cold welding meet sb. at the airport be with fast and high pressure make two kinds of metal wire rods reach molecular separation, thereby the principle of generation metallic bond designs.Side at this welding machine is provided with handle, end at handle is equipped with a cam, the both sides of cam contact with two pushing blocks, the end in addition of pushing block respectively is hinged on the lever arm, lever arm all is hinged on the bearing with little axle, connects with a return spring in the lower end of two lever arms, and one of lever arm is held with hinge in addition and is connected with the cover plate of compact heap, in the endoporus of compact heap, ejector pin is housed, between the flat end of ejector pin and the cover plate holddown spring is housed.Be provided with a mould between two compact heaps, it is made up of two half blocks, on the symmetrical surface of contact of two half blocks the hole is arranged respectively half, lumps together to form a hole that is complementary with the gauge or diameter of wire of processing.Two half block moulds respectively are fixed on the compact heap with pressing plate and plate screw; Be provided with in the both lateral sides of mould and be used to handle the handwheel of dop and movably dop push pedal.

By accompanying drawing embodiment of the present utility model is elaborated below:

Fig. 1 is a Facad structure schematic representation of the present utility model

Fig. 2 overlooks partial sectional view for the utility model

As shown in Figure 1, 2: metal wire rod cold welding is met sb. at the airport and is provided with handle 1, end at handle 1 is equipped with a cam 2, both sides at cam 2 contact with two pushing blocks 3, and the end in addition of two pushing blocks 3 respectively is hinged on the lever arm 4, and lever arm 4 all is hinged on the bearing 6 with little axle 5; Lower end at two lever arms 4 connects with a return spring 7; The in addition end of lever arm 4 is connected with the cover plate 10 of compact heap 9 with hinge 8, and ejector pin 11 is housed in the endoporus of compact heap 9, between the flat end of ejector pin 11 and cover plate 10 holddown spring 12 is housed; Be provided with a mould 13 between two compact heaps 9, it is made up of two half blocks, and the hole is respectively arranged half on the surface of contact of two relative half blocks, lumps together to form a hole that is complementary with the gauge or diameter of wire of processing; Two half blocks respectively are fixed on the compact heap 9 with pressing plate 14 and plate screw 15; Be provided with in the both lateral sides of mould 13 and be used for handling the handwheel 17 of dop 16 and movably dop push pedal 18.

The equipment work process is: handwheel 17 is rotated, and dop push pedal 18 moves inwards, and dop 16 opens, and inserts two wire rods to mould 13, unclamps handwheel 17, and dop 16 closures are fixed wire rod.Action force is delivered in the multiplication of voltage system through cam 2, drive block 3 by the handle 1 of pressurizing system, by lever arm 4 pressure is increased, and passes to pressing system, in lever arm 4 bottoms return spring 7 is housed, and can make lever arm 4 get back to original position.Adopted ejector pin 11 to withstand mould 13 in the pressing system, make mould 13 vertically closed earlier when stressed, two wire rods are compressed, increasing mould 13 with pressure is being with wire rod laterally to push, the two Metal Contact faces that make reach molecular separation and produce metal chain, finished the connection of wire rod,, two wire rods have reliably been connected as long as give handle 1 increase and decrease pressure repeatedly.

All metal cold press welders according to above-mentioned principle and structure characteristic all belong to protection domain of the present utility model.
