Embodiment 1

[0037] Example 1 is basically as attached Figure 1 and Figure 2 As shown:

[0038] Distribution box door plate beveled process, the use of beveled special mold, the special mold includes the upper die 10 and the lower die base 11, at the bottom of the upper die 10 is provided with two punch surfaces, the two punch surfaces relative to the centerline of the upper die 10 symmetrical setting, wherein the bump surface includes the raised side 12 and set on both sides of the raised side 12 side 13, the raised edge 12 and the side 13 are set horizontally, the raised edge 12 and the side 13 form a bevel 14, the angle between the bevel 14 and the horizontal plane is not less than 30 °, The angle of the present application is 33 °.

[0039] On the raised edge 12 is fixed a plurality of open punches 15, a plurality of open punches 15 are distributed on the raised edge 12, the open punch 15 is used to flush the heat dissipation hole on the door plate 1, near the upper die 10 centerline of th...

Embodiment 2

[0049] Example 2 is basically as attached Figure 4 As shown:

[0050] The difference with Example 1 is that: the load-bearing plate 20 sliding connection in the first housing chamber 18, and the bottom of the first support chamber 18 is fixed with a plurality of support frames 25, adjacent support frames 25 form a gap, and the width of the gap is greater than the aperture of the blanking hole 21, there are multiple elastic pieces fixed between the load-bearing plate 20 and the support frame 25, when the load-bearing plate 20 is not stressed, its top surface exceeds the bottom surface of the die groove 17, in order to prevent the load-bearing plate 20 from shaking, the load-bearing plate 20 is set to a rectangular plate, And on the side of the load-bearing plate 20 fixed a plurality of limit blocks 27, a plurality of limit blocks 27 are distributed on the four sides of the load-bearing plate 20 13, the first holding chamber 18 on the side wall of a plurality of vertical slots 28, lim...

Abstract

The invention relates to the technical field of distribution box preparation, and specifically discloses a beveled edge process for a door panel of a distribution box. A special mold for the beveled edge is used. The special mold includes an upper die head and a lower die seat. The mold surface includes a raised edge and a side edge, and a hypotenuse is formed between the raised edge and the side edge, and a plurality of opening punches are evenly distributed on the raised edge, and keyhole punches are arranged on the sides, and the lower mold seat There is a die groove on the top, and the bottom of the die groove is provided with a first receiving cavity and a second receiving cavity; the specific steps are: fix the upper die head on the hydraulic equipment, fix the lower die base on the punching machine; The two door panels for molding and punching are placed on the lower die base, and the two door panels are placed symmetrically with respect to the center line of the upper die head; the upper die head is driven to move downward, and the punching and punching of the two door panels are completed at the same time. Adopting the technology in this patent not only improves the efficiency of door panel production, but also prolongs the service life of the mould.

Description

Technical field [0001] The present invention relates to the field of distribution box preparation technology, in particular to the distribution box door plate beveled process. Background [0002] High-voltage distribution box refers to electrical products used in power system power generation, transmission, distribution, power conversion and consumption to play a role in on-off, control or protection, with a voltage level of 3.6kV ~ 550kV, mainly including high-voltage circuit breakers, high-voltage isolators and grounding switches, high-voltage automatic reclosers and segmenters and high-voltage switchgear. [0003] Because the electrical appliances in the distribution box will produce a certain amount of heat when working, so it is necessary to open a heat dissipation hole on the box wall or box door, but if the distribution box is used in the outdoor environment is relatively harsh, at this time, the dust from the outside world, crawlers, etc. will enter the inside of the box ...
