Technical Field

The utility model relates to an electric power equipment processing technology field specifically is an angle steel earthing pole dashes closed angle mould.

Background

The angle steel grounding electrode is widely applied to electric power equipment, and when the angle steel grounding electrode is used, the angle steel grounding electrode needs to be vertically driven into the ground, so that a sharp corner needs to be machined at one end of the angle steel grounding electrode, and the angle steel grounding electrode is convenient to drive into the ground. In the prior art, when the sharp angle of the angle steel is machined, a shearing method is adopted, the method needs to carry out shearing twice, needs to turn over, has very low efficiency and cannot meet the production requirement. CN 207996929U discloses a grounding electrode punching and shearing die, which is used for processing sharp corners of angle steel, but the upper scissors adopts a split fixed type, the lower tool adopts a concave die, which is not only difficult to process when manufacturing the die, but also when in use, because the cutting edge of the tool is very thin, the tool is very easy to break, the lower tool is invalid, the maintenance is very troublesome, and the problem of mass and quick production cannot be well solved.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to overcome the problems, the angle steel grounding electrode sharp angle punching die is provided.

The utility model provides a technical scheme that its technical problem adopted is: an angle steel grounding electrode sharp corner punching die comprises an upper die assembly and a lower die assembly, wherein the upper die assembly is fixed on an upper workbench of a punching machine through a fastener and comprises an upper die plate, and an upper die base is arranged on the upper die plate; the lower die assembly is fixed on a lower workbench of the punch through a pressing plate and comprises a lower die plate, a lower die base is arranged on the lower die plate, an upper shearing die is connected onto the upper die base through a fastener and is cuboid, and an upper cutting edge which is vertically arranged and is V-shaped and inwards concave is arranged on one side of the upper shearing die. The bottom surface of the upper cutting edge in the structure is a plane, so that the cutter is convenient to sharpen.

Be equipped with down on the die holder and cut the mould, the cross section of cutting the mould down be with angle steel assorted V-arrangement that falls, constitute two back knife faces of cutting the mould down, the front end of cutting the mould down is equipped with two rake faces that are the V-arrangement and arrange, and its angle with go up the blade phase-match, two rake faces with the intersection line that two back knife faces formed constitutes two lower blades.

The utility model has the advantages that:

1. the utility model adopts an integral upper cutting edge, which increases the strength of the cutter body and prolongs the service life of the cutter;

2. the utility model discloses a lower shearing die adopts the terrace die formula design, has changed the weak link at cutting edge position, has improved the intensity of mould to production efficiency has been improved.
