Inner swing door sheet bending machine convenient to load

Abstract

The invention discloses an inner swing door sheet bending machine convenient to load. The machine comprises a frame, and further comprises two parallel slide rails and two bending female molds; the two bending female molds are slidingly arranged on the two slide rails; the machine further comprises a driving chain and a driving motor; the bending female molds are connected to the driving chain; and the driving motor drives the bending female molds to slide along the slide rails through the driving chain. The machine further comprises a bending male mold and a bending male mold lifting mechanism; and the bending male mold lifting mechanism comprises a mold fixing rod, two vertical linkage rods, a linkage beam, a hydraulic cylinder, and two slide sleeves. The hydraulic cylinder is used for pushing the linkage beam; and the linkage beam drives the mold fixing rod through a linkage rod driving mold, so that the bending male mold is driven to realize 180-degree bending of steel plates without interfering with the steel plates. Meanwhile, when one bending female mold performs the bending operation, the other female mold moves to one side for loading; and the loading and the bending are performed at the same time to greatly improve the operation efficiency.

Description

technical field [0001] The invention relates to a bending machine, in particular to an inner swing door panel bending machine which is convenient for loading materials. Background technique [0002] In the production process of the inner swing door, in order to reduce the welding process and improve the overall strength of the door, the steel plate is bent once (180 degrees) by a bending machine to form an inner swing door with two sides parallel to each other and a U-shaped bottom. However, the bending mold of the traditional bending machine is directly driven by the hydraulic cylinder, and is limited by the thickness of the door panel. After bending 180 degrees, the distance between the two sides of the steel plate is small, and the hydraulic cylinder cannot be extended. If a small hydraulic cylinder is used, One is that the strength cannot be guaranteed, and the equipment is easily damaged. On the other hand, due to its pressure, the product quality cannot be guaranteed. ...

AI Technical Summary

Problems solved by technology

However, the bending mold of the traditional bending machine is directly driven by the hydraulic cylinder, and is limited by the thickness of the door panel. After bending 180 degrees, the distance between the two sides of the steel plate is small, and the hydraulic cylinder cannot be extended. If a small hydraulic cylinder is used, One is that the strength cannot be guaranteed, and the equipment is easily damaged. On the other hand, due to its pressure, the product quality cannot be guaranteed

Therefore, the traditional structure of the bending machine can not work

[0003] In addition, the traditional bending machine operation process includes sequential loading, bending, and unloading, which cannot be carried out at the same time, which affects production efficiency
