Description

Trapezoidal box molding tool

Technical Field

The utility model relates to the technical field of plate processing, in particular to a trapezoidal box pressing tool.

Background

To bend the plate shown in fig. 1 into a trapezoidal box shown in fig. 2, the prior art needs to bend the plate three times or four times by using a sheet metal bending machine, so that the efficiency is low; the heights of the bent edges are not consistent, so that the positioning is not easy; meanwhile, the bent edge interferes with the edge being bent during the final bending step, and a special bending upper die needs to be manufactured.

SUMMERY OF THE UTILITY MODEL

In order to overcome one of the defects or shortcomings of the prior art, the utility model discloses a trapezoidal box pressing tool, which adopts the technical scheme that:

the utility model provides a trapezoidal box die mould frock, includes the upper plate with press top panel rigid coupling, with the bottom plate of press bottom panel rigid coupling, its characterized in that: the upper plate is connected with a male die through a bolt, the bottom plate is connected with a female die through a bolt, the outline of the male die corresponds to the outline of the inner cavity of the trapezoidal box, and the height of the male die is more than or equal to the maximum depth of the trapezoidal box; the profile of the female die corresponds to the profile of the trapezoidal box, and the height of the female die is less than or equal to the minimum depth of the trapezoidal box.

Furthermore, a clamping groove corresponding to the outline of the plate before the trapezoidal box pressing is formed in the upper surface of the female die, and the depth of the clamping groove is smaller than or equal to the thickness of the plate.

Furthermore, a plurality of release holes are uniformly formed in each bending line of the plate.

Furthermore, the clamping grooves do not completely correspond to the outline of the plate, and a part of the plate is positioned outside the female die.

Furthermore, the inner side wall of the female die is in arc transition with the upper surface of the female die.

Compared with the prior art, the utility model has the advantages of one-step forming and higher efficiency; the plate is limited by the clamping groove at the upper part of the female die, so that the precision is higher; the operation is more convenient, need not change different last moulds many times and bend.

Detailed Description

The trapezoidal box press-forming tool comprises an upper plate 1 fixedly connected with an upper panel of a press machine and a bottom plate 2 fixedly connected with a lower panel of the press machine, wherein the upper plate 1 is connected with a male die 3 through a bolt, the bottom plate 2 is connected with a female die 4 through a bolt, the outline of the male die 3 corresponds to the outline of an inner cavity of a trapezoidal box 100, and the height of the male die is greater than or equal to the maximum depth of the trapezoidal box 100; the outline of the female die 4 corresponds to the outline of the trapezoidal box 100, and the height of the female die is less than or equal to the minimum depth of the trapezoidal box 100.

The upper surface of the female die 4 is provided with a clamping groove 41 corresponding to the outline of the trapezoidal box-pressed front plate 100 ', the depth of the clamping groove 41 is smaller than or equal to the thickness of the plate 100', the pressed plate can be limited, and the pressing precision is guaranteed. The engaging grooves 41 do not completely correspond to the contour of the sheet 100 ', and a part of the sheet 100' is located outside the female die 4. The inner side wall of the concave die 4 is transited with the upper surface thereof through an arc 42. A plurality of release holes 101 are uniformly formed on each bending line of the plate material 100'.

As shown in fig. 4, the pressed plate material is placed in the clamping groove 41 of the female die 4, the press is started, as shown in fig. 5, the male die 3 is completely pressed into the female die, then as shown in fig. 6, the press drives the male die 3 to ascend, so that the one-time bending forming of four edges of the product can be realized, and the formed trapezoidal box 100 can be taken down, so that the steps are repeated in a circulating manner, and the efficiency is very high. The plate is limited by the clamping groove at the upper part of the female die, so that the precision is higher; the operation is more convenient, need not change different last moulds many times and bend.
