Description

Automatic female row's through-hole burr cutting equipment of counterpointing

Technical Field

The utility model relates to a female processing technology field of arranging, in particular to female row's of automatic counterpoint through-hole burr cutting equipment.

Background

The busbar is the main material of the high-low voltage switch cabinet busbar, in most use occasions, the main connection mode of the busbar is connected by using a bolt, the busbar overlapping interface needs to be provided with holes by using the bolt, and the main modes of the holes are punching, hydraulic hole opening or drilling. No matter the hole is opened in the above mode, burrs are generated on the periphery of the bottom of the busbar through hole.

If the burrs of the through holes of the busbars are not eliminated, the busbar interfaces cannot be tightly attached, the busbar backflow resistance is increased, the temperature rise is increased, and the adjacent contact interfaces generate oxidation reaction in the operation of the high-low voltage switch cabinet, so that accidents are caused, and potential hazards are caused to the safe operation of the high-low voltage switch cabinet. In the traditional deburring method, a round hole is drilled and chamfered, and special-shaped holes such as a long waist hole and a square hole are scraped by a scraper or filed by a file, so that the two methods have low efficiency, the surface of the busbar is easy to damage, and the deburring effect is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an automatic female row's of counterpointing through-hole burr cutting equipment, its burr through female row of going up the through-hole of mould extrusion cutting, chamfer department takes shape beautifully, and the surface is smooth, does not form the damage to female row surface, has effectively improved the yield and the efficiency of production.

The above technical purpose of the present invention can be achieved by the following technical solutions:

the utility model provides an automatic female row's of counterpointing through-hole burr cutting equipment, includes the frame, be provided with in the frame and be used for fixed female mould seat of arranging, set up on the mould seat and with female relative mould of arranging, be used for the mould punching press to female arranging and make the mould embedding female stamping device who arranges the through-hole on arranging, be equipped with on the mould with the arch of female through-hole looks adaptation of arranging, the top of mould seat is provided with and is used for holding female spout of arranging and is used for connecting the elastic component of mould seat and mould, female row slides and slides on the orientation of seting up of spout and slides with the spout and is.

By adopting the technical scheme, when the die is pressed by the stamping device, the elastic piece is pressed and moves towards the busbar, and the bulge on the die is embedded into the through hole on the busbar and slides inwards until the surface of the die is abutted against the surface of the busbar. In the process, the burrs on the busbar through holes and the extrusion surface of the die are extruded and deformed to form chamfers until the busbar abuts against the surface of the die, and the deformation is terminated.
