Abstract

This utility model is specially a kind of flush weld tool joint trimmer, solves the problems, such as that existing flush weld tool joint has poor mechanical property, shaping effect difference and shaping inefficiency.Including cylindrical compression bearing, shoulder hole of the left side with diameter greater than right side diameter is provided with cylindrical compression bearing, and on the left of cylindrical compression bearing, it is provided with stepped compression sleeve of the left side with diameter greater than right side diameter, the center bore of stepped compression sleeve is identical with aperture on the right side of shoulder hole, the right side external diameter of stepped compression sleeve is identical with the left side aperture of cylindrical compression bearing, and the corresponding guide through hole of right position is provided with the end face of cylindrical compression bearing and stepped compression sleeve.This utility model reasonable in design reliability, effectively increases the mechanical property of flush weld tool joint, and prevented burr at flush weld tool joint, bloom, the generation of seminess, shaping effect is substantially improved, while convenient to operation, improves working performance.

Description

Flush weld tool joint trimmer
Technical field
This utility model is related to reinforcing bar flash butt welding apparatus for shaping, specially a kind of flush weld tool joint trimmer.
Background technology
Reinforcing bar flash butt welding is that two reinforcing bars are placed into docking form, makes contact point metal molten using resistance heat, is produced It is strong to splash, flash of light is formed, it is rapid to apply a kind of press welding method that upset force is completed.The technical process of flash butt welding includes continuously Flash of light and compressing process.
During welding, primary circuit is first closed, make two reinforcing bar end face gentle touchdowns, now eject in the gap of end face Molten metal microgranule flash of light as spark, then mobile reinforcing bar makes both ends of the surface still keep gentle touchdown slowly, forms group flashing light. When flash of light to predetermined length, when making steel bar end be heated to nearly fusing point, upset is carried out rapidly with certain pressure just.First band Electric upset, then current-off upset is to certain length, welding point is accused and is completed.
But after the completion of flush weld tool joint exist burr, bloom, the defect such as crackle, the mechanics having a strong impact at solder joint Performance, and shaping effect is poor, at the same reforming process waste time and energy, inefficiency.
The content of the invention
There is poor mechanical property, shaping effect difference and shaping efficiency to solve existing flush weld tool joint in this utility model A kind of low problem, there is provided flush weld tool joint trimmer.
This utility model adopts the following technical scheme that realization:Flush weld tool joint trimmer, including cylindrical compression Seat, is provided with shoulder hole of the left side with diameter greater than right side diameter, and is provided with the left of cylindrical compression bearing on cylindrical compression bearing Stepped compression sleeve of the left side with diameter greater than right side diameter, aperture on the right side of the center bore and shoulder hole of stepped compression sleeve Identical, the right side external diameter of stepped compression sleeve is identical with the left side aperture of cylindrical compression bearing, cylindrical compression bearing and ladder The corresponding guide through hole of right position is provided with the end face of shape compression sleeve.
During operation, lead column is penetrated in guide through hole, subsequently by it is two reinforcing bars corresponding penetrate cylindrical compression bearing and In stepped compression sleeve, when the adjacent heating one end of two reinforcing bars is to nearly fusing point, by hydraulic jack or other engines Structure drives stepped compression sleeve to extrude to cylindrical compression bearing rapidly, realizes that burr to steel bar butt welding joint etc. is carried out Shear extrusion, and solder joint can be pressed further by, overcome existing flush weld tool joint exist poor mechanical property, shaping effect difference and The problem of shaping inefficiency.
This utility model reasonable in design reliability, effectively increases the mechanical property of flush weld tool joint, and prevents Burr at flush weld tool joint, bloom, the generation of seminess, shaping effect is substantially improved, while convenient to operation, carries High working performance, has the advantages that simple structure, easy to process and low cost.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure:1- cylindrical compression bearings, 2- shoulder holes, the stepped compression sleeves of 3-, 4- guide through hole.
Specific embodiment
Flush weld tool joint trimmer, including cylindrical compression bearing 1, be provided with cylindrical compression bearing 1 left side with diameter greater than The shoulder hole 2 of right side diameter, and the left side of cylindrical compression bearing 1 is provided with stepped extruding of the left side with diameter greater than right side diameter Sleeve 3, the center bore of stepped compression sleeve 3 are identical with 2 right side aperture of shoulder hole, outside the right side of stepped compression sleeve 3 Footpath is identical with the left side aperture of cylindrical compression bearing 1, is respectively provided with the end face of cylindrical compression bearing 1 and stepped compression sleeve 3 There is the corresponding guide through hole of right position 4.
