Description

Technical Field

[0001] The present disclosure relates to the technical field of metal bending, and in particular to a metal bending machine. Background Art

[0002] Metal sheets are plate-like items made of metal materials. During the use of metal sheets, they need to be bent by a bending machine according to different usage requirements. A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench consists of a base and a pressure plate. At present, the bending angle of the bending machine is not easy to adjust, and different bending molds need to be replaced and installed, which is relatively complicated. Utility Model Content

[0003] The purpose of the utility model is to provide a metal bending machine in order to solve the above problems.

[0004] The technical solution of the present disclosure is achieved as follows:

[0005] The present disclosure provides a metal bending machine, comprising a base, a support frame, a hydraulic cylinder, a bending head, a limiting frame and a bending die mechanism, wherein the support frame is fixedly mounted on the base, the hydraulic cylinder is mounted on the support frame, and the output end of the hydraulic cylinder is mounted on the bending head, the limiting frame is connected to the base, and the bending die mechanism is located between the base and the bending head. In this technical solution, the bending die mechanism moves along the base and the limiting frame according to different bending angle requirements, and the bending head is driven by the hydraulic cylinder to descend to perform bending work, which facilitates adjustment of different bending dies for use;

[0006] The bending die mechanism includes a fixed frame, a limiting screw hole, a bending die and a limiting screw. The fixed frame is arranged below the limiting frame. The limiting screw hole and the fixed frame are an integrated structure. The bending die are provided with a plurality of them respectively fixedly connected to the fixed frame, and the plurality of bending dies are arranged in parallel along the fixed frame, and the arrangement spacing of the plurality of bending dies gradually decreases from left to right. The limiting screw passes through the support frame and is connected to the limiting screw hole.

[0007] In the above technical solution, the bending dies with different spacings can be adjusted and moved under the bending head according to different bending angle requirements, thereby speeding up the adjustment speed of the equipment. At the same time, they are fixed by limiting screws and limiting screw holes to prevent displacement during the bending process, thereby increasing the stability of the bending process.

[0008] In one embodiment, a raised base is provided at the bottom of the fixed frame, which is connected to the base to raise the height of the fixed frame. The middle part of the raised base is a hollow structure, the bottom surface of the fixed frame is in contact with the raised base, and the top surface of the fixed frame is in contact with the limiting frame. In this technical solution, the height of the bending mold is increased by raising the base, and the bending range is increased, thereby preventing the metal sheet from contacting the base at the bottom due to excessive bending angle, and thus being unable to continue to be pressed down and bent.

[0009] In one embodiment, limiting screw holes are provided on both sides of the fixed frame, and the limiting screw is provided with two limiting screw holes that pass through both sides of the support frame and are connected to both sides of the fixed frame respectively. There are several limiting screw holes, and several of the limiting screw holes are respectively located in the center position between each bending die, so as to limit the fixed frame and position the midpoint position of each bending die at the same time. In this technical solution, by setting the limiting screw hole at the midpoint position between each bending die, it is convenient to position the midpoint position of the bending die and align it with the bending head, thereby preventing the bending die from being placed incorrectly.

[0010] In one embodiment, four limiting frames are provided and are respectively located on both sides of the fixed frame. In this technical solution, the limiting frames can effectively limit the fixed frame and prevent it from warping during the bending process.

[0011] In one embodiment, the length of the bending head is less than the length of the bending die. In this technical solution, the bending head can drive the plate to continue to descend and bend through the bending dies during the bending process.

[0012] The advantages or beneficial effects of the above technical solution include at least:

[0013] The present invention discloses a metal bending machine, which can adjust the bending dies of different spacings to move under the bending head according to different bending angle requirements, thereby accelerating the adjustment speed of the equipment. At the same time, the limiting screw and the limiting screw hole are used to fix the bending die to prevent displacement during the bending process, thereby increasing the stability of the bending process.

[0014] At the same time, by setting the limiting screw hole at the midpoint between each bending die, it is convenient to align the midpoint of the bending die with the bending head to prevent the bending die from being placed incorrectly. BRIEF DESCRIPTION OF THE DRAWINGS
