Upward-90-degree bending double-bending die strip and bending machine

Abstract

The invention discloses an upward-90-degree bending double-bending die strip and a bending machine. The double-bending die strip comprises a first bending die strip and a second bending die strip. Thesecond bending die strip is horizontally and movably arranged on one side of the first bending die strip through a second bending die strip horizontal moving mechanism. The first bending die strip atleast comprises a pressing face, a bending angle is formed at the front end of the pressing face, and the bending angle is inwards bent by the acute angle. The side, close to the first bending die strip, of the second bending die strip is provided with a bending face, and the lower end of the bending face downwards extends in a hook shape. The bending machine comprises a bending swinging mechanism, a bending overturning mechanism, a lower die mechanism, a conveying mechanism and a side positioning mechanism. A die head of the first bending die strip is horizontally arranged, the second bending die strip is vertically arranged, 90-degree bending or clamping bending of a plate in the small gap can be achieved, and the bending efficiency is improved.

Description

technical field [0001] The invention relates to an upward 90-degree double-bending mold bar and a bending machine, belonging to the technical field of bending equipment. Background technique [0002] At present, the labyrinth grooves of the side panels of the refrigerator and the top panel of the refrigerator are generally realized by means of rolling mills. The existing rolling mills have the following disadvantages: (1) the section cannot be changed once it is determined; (2) it is very difficult to install and debug. It is complicated and requires very professional installation and commissioning personnel; (3) It cannot be compatible with sheets with too large differences in thickness and material; (4) There are some differences between the rolling section and the theoretical design. In view of the above problems, a bending machine is used to bend the side panels and the top panel of the refrigerator into the required labyrinth grooves. However, the existing bending machi...

Problems solved by technology

[0002] At present, the labyrinth grooves of the side panels of the refrigerator and the top panel of the refrigerator are generally realized by means of rolling mills. The existing rolling mills have the following disadvantages: (1) the section cannot be changed once it is determined; (2) it is very difficult to install and debug. It is complicated and requires very professional installation and commissioning personnel; (3) It cannot be compatible with sheets with too large differences in thickness and material; (4) There are some differences between the rolling section and the theoretical design

In view of the above problems, a bending machine is used to bend the side panels and the top panel of the refrigerator into the required labyrinth grooves. However, the existing bending machine adopts the limitation of multiple bending methods, which makes the upper bending part and the lower bottom plate in a small 90-degree bends or clamped bends that cannot be achieved when there is a gap
