A steel plate bending machine with adjustable bending depth

Abstract

The invention discloses a bending depth adjustable type steel plate bending machine. The machine comprises a bottom plate, wherein a left threaded column and a right threaded column are symmetricallyand fixedly arranged on the bottom plate, a first bending module is arranged on a first air cylinder, a nut base is movably arranged on a lead screw, a second air cylinder is arranged on the side, close to the bottom plate, of the nut base, the second air cylinder is provided with a second bending module, an inner cavity of the bottom plate is symmetrically and fixedly provided with special-shapedpistons, a fixed rotating shaft is fixedly arranged in a groove of a concave block, a rotating rod is movably arranged on the fixed rotating shaft in a penetrating mode, and a clamping block is fixedly arranged on the rotating rod. The bending depth adjustable type steel plate bending machine is internally provided with two bending structures, the machine can be independently used, and can further be used for two-different-form bending processing on a steel plate at the same time, meanwhile, the bending position and the bending depth in the machine can be precisely adjusted, dynamic clampingstructures on the two sides also enable the steel plate to be effectively fixed in the bending process, and the effect is good.

Description

technical field [0001] The invention relates to the technical field of bending machines, in particular to a steel plate bending machine with adjustable bending depth. Background technique [0002] In the prior art, a steel plate bending device with the application number "201810949878.8" includes an installation platform. A compression plate is provided at the front of the installation platform, and compression motors are provided on both sides of the compression plate. The motor shaft of the motor passes through the pressing plate and connects with the lead screw Ⅲ. The stainless steel plate is installed on the installation platform, and the pressing motor rotates to drive the pressing plate to complete the pressing of the stainless steel plate. There is a bending frame and a screw in front of the installation platform. One end of Ⅱ is connected to the installation platform, and the other end is connected to the adjusting motor through the bending frame. There is a rectangu...

AI Technical Summary

Problems solved by technology

[0003] However, there are still obvious defects in its use: 1. The above-mentioned device is only provided with a single bending motor, which can only complete one bending, and cannot meet the needs of two bendings of the steel plate at the same time, and the efficiency is relatively low. 2. The position of the bending motor in the above-mentioned device is fixed. When the bending position of the steel plate is adjusted, the above-mentioned device cannot be used, and the adaptability is poor; 3. The bending depth of the steel plate is not limited in the above-mentioned device. The position and adjustment structure cannot meet the diverse processing needs; 4. The above-mentioned device lacks a structure for dynamically clamping the steel plate. As the steel plate is gradually bent, the straight-line distance between the two ends of the steel plate is constantly shrinking, so a kind of The dynamic clamping structure limits the position of the steel plate to avoid bending deviation
