Embodiment Construction

[0021] The hinged sheet nesting type progressive die with rolled tube provided in this embodiment includes the following main components:

[0022] 1. Cutting the progressive die part, such as figure 1 , figure 2 As shown, it consists of an upper mold and a lower mold. The upper mold includes an upper template 9, and the lower part of the upper template 9 is connected with the upper backing plate 8, the fixing plate 7 and the discharge plate 6 with screws in turn. The front part of the upper mold is provided with a A set of stirrup hole punches 10, a set of guide nails 11; a three-claw pre-punch 12 for a three-claw sheet, a three-claw punch 13, and a two-claw trimming punch for a two-claw sheet are arranged in sequence at the rear of the upper die 14 and two claw punches 15. The lower mold includes a lower template 2 and a connected mold base 1. The lower template 2 is connected with the lower backing plates 3, 4 and the concave template 5 in sequence, corresponding to each ...

Abstract

A hinge blade nest cutting winding progressive die comprises up die and bottom die and the connecting guide post, with the up die having stirrup punch head, three claw punch head and two claw punch head, with the bottom die having stirrup, three claw die and two claw die, with the later tow having a horizontal slide path, one side of which having a discharge device linked with the up die, bendingdie linked with the up die on the other side, and the winding die. It realizes the one time forming with the stirrup, shear cutting, bending and winding, with precision and improved production efficiency and reduced cost. One set of die, a punch machine and an operator will get everything done.

Description

technical field [0001] The invention relates to a mold for producing hinge sheets, in particular to an automatic high-precision mold for one-time molding of sheet nesting, pre-bending, and tube rolling. technical background [0002] At present, in the production process of hinge sheets, progressive dies are mostly used in single-process production. The sheet parts in the progressive dies are nested, and the material utilization rate is high. If it is used in conjunction with a single process, there is an intermediate process, and there is a problem of intermediate switching, which occupies equipment and personnel, and the efficiency is low. If the material cost of the part is not considered (that is, without nesting), it is also possible to achieve the one-time forming of the entire hinge (hinge), but it causes a great waste of part materials. In fact, no one do this. To sum up, the problem with the current hinge molds is that if nesting is used to ensure the utilization r...
