Abstract

The utility model relates to a bus flat end surface shearing die, which comprises an upper die, a lower die and a die holder, wherein the die holder is used for fixing the upper die and the lower die. The bus flat end surface shearing die is characterized in that the lower die is a planer blade, a cutting edge is arranged on one side of the planer blade, and the upper die is provided with a single-edge sharp blade only so as to match with the planar blade of the lower die to shear buses. As the lower die is the planar blade and the upper die is provided with the single-edge sharp blade, the bus flat end surface shearing die is not only suitable for blanking operation but also suitable for processing copper bus and aluminum bus with different hardness and thicknesses, particularly, when in shearing for blanking operation, materials are not required to be removed, and the shearing die can replace a milling machine to cut out flat end surfaces of the buses when the length of the buses is required to be processed.

Description

Bus planar end surface shearing die
Technical field
The utility model relates to a kind of shearing die of electrician's bus, particularly bus planar end surface shearing die.
Background technology
When making electrician's bus, all need to adopt the bus shearing die that bus section bar copper or aluminium row are cut off cutting stock, the operating position of shearing die affects the operating efficiency of bus manufacturing and the utilization rate of material to a certain extent.At present, existing bus shearing die has four kinds, is respectively the plate shearing machine formula, upper slitter Eight characters form, and sharp up and down sword formula, also having a kind of is exactly the two-sided cut-out blanking type that needs to remove material.The bus end face of these four kinds of shearing die blankings is no matter which end all can not form smooth end face well, and the demanding bus of end face all will carry out Milling Process or spend the more time to repair at last end face; Though blanking blanking type certain limit can form smooth end face, but want waste material, and only be fit to the bus that the stamping-out material is harder, crisp, thickness is little, not so, two end faces of the bus of blanking all can have the very big angle of collapsing, and the weak more angle of the big more hardness of thickness is big more; The bus soft to material also can occur very serious because the burr limit that pultrusion causes such as aluminium busbar.And above-mentioned these shearing dies are except the blanking work of doing first procedure, and all in the end a procedure need add bus length and substitutes milling machine man-hour and process smooth end face.So,, manufacture and design a kind of novel bus shearing die and be very important at above problem.
Summary of the invention
Order of the present utility model is to provide a kind of bus planar end surface shearing die, and this bus planar end surface shearing die is not only simple in structure, reasonable in design, and can process the bus of flat end face.
The utility model bus planar end surface shearing die comprises upper die and lower die, and the die holder that is used for fixing upper and lower mould, it is characterized in that: described counterdie is the plane sword, be positioned at the cutting edge that is of one side, patrix only has monolateral sharp sword, shears bus to cooperate with the plane sword of counterdie.
The utility model bus planar end surface shearing die is the plane sword by counterdie, patrix only has monolateral sharp sword, thereby make it not only be fit to blanking work, and blanking not only do not need to remove material when shearing, can need add at bus length again and substitute milling machine man-hour it is sheared out smooth end face; Simultaneously can be fit to the hardness difference, the copper busbar that thickness is different and the processing of aluminium busbar.
Description of drawings
Fig. 1 is the front view of bus planar end surface shearing die;
Fig. 2 is the vertical view of bus planar end surface shearing die;
Wherein die shank 1, upper bolster 2, guide pin bushing 3, guide pillar 4, ejector spring 5, die shoe 6, location supporting plate 7, patrix 8, hexagon socket countersunk flat cap head screw 9, counterdie 10, alignment pin 11, holding pad 12, binder rubber 13, binder guide rod 14.
The specific embodiment
The utility model bus planar end surface shearing die, comprise patrix 8 and counterdie 10, and be used for fixing, the die holder 2 of counterdie, 6, counterdie 8 is the plane sword, be positioned at the cutting edge that is of one side, patrix only has monolateral sharp sword, shear bus to cooperate with the plane sword of counterdie, the basil of point sword is less than 45 °, what patrix adopted is the form of monolateral sharp sword, can reduce shearing force, particularly can shear out do not collapse the fully flat end face at angle of an end, do not need other processing promptly to can be used as line after the blanking, bending, the location datum level of punching etc. operations simultaneously owing to the less oblique angle that forms of sharp basil degree is also very little, needs only to repair a little with portable abrasive machine and can satisfy instructions for use.
The place has Baltimore groove 15 near patrix point sword, and the cracking problem takes place when avoiding patrix heat treatment rounding off in the Baltimore groove; The purpose of recessing: the one, for the sharpening of blade; The 2nd, can make when shearing bus at the end face of oblique this end of sword more smooth, reducing post processing or process time, the size of groove and determine according to thickness and the edge strength of shearing bus from the distance on blade limit.
Be positioned at monolateral sharp sword inboard and be provided with the binder seat, the binder seat is followed successively by holding pad 12, binder rubber 13 from bottom to top, be equipped with binder guide rod 14 on upper bolster 2 and the binder rubber 13, these binder guide rod 14 matched in clearance are passed upper bolster 2 and binder rubber 13, and its front end and holding pad 12 are fixing.
Be provided with ejector spring between the upper die and lower die, adopt the spring demoulding, make under the situation that die shank not have to link together with press ram, patrix also can unclamp automatically when pressure slider retreats.That this structure both had been fit to was horizontal, also be fit to vertical hydraulic bus processing machine, both can work as long as move to during use to have good positioning on the station of bus processing machine, did not want special anchor clamps and fixed, and had made things convenient for use.
8 is the patrix of monolateral sharp sword as can be seen from Figure 2, and interference fits is embedded on the upper bolster, fixes with soket head cap screw; What be close to installation is to pass fixedly holding pad 12 of upper mould fixed plate and binder rubber 13 with binder guide rod 14 matched in clearance; Counterdie 10 is the common planar cutting edge, adopts straight pin location, soket head cap screw to be fixed on the die shoe.Wherein the blade of patrix 8 adopts monolateral wedge angle so that the bus end face that this end of flat sword is sheared is definitely smooth; And the angle of oblique sword adopts the wedge angle forms less than 45 degree, and holding pad 12 downsides are installed near location supporting plate 7, and height dimension is got the upper and lower mould edge length and promptly sheared about 60% of bus Breadth Maximum, and it is fixed specifically also will to come according to the width specifications of bus.
The utility model bus planar end surface shearing die compared with prior art, have reasonable in design, structural reduction, blanking is sheared and need not be wasted the bus material; Particularly can process smooth end face as the milling machine sample for the last length of bus and end face processing, and faster convenience, the operating efficiency that bus is made improved.
