Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet shell processing technology, specifically a bending machine for processing power distribution cabinet shells. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. They are used in situations where the load is relatively dispersed and there are few circuits. The housing of the distribution cabinet is made of cold-rolled steel sheet material, which is bent and welded. According to the patent document with authorization announcement number CN218611196U, entitled "A sheet metal bending machine for manufacturing distribution cabinet housings", the housing is first placed on a placement plate. The first telescopic component and the first drive component work to bend the housing. The fixing frame fits the housing to prevent the push plate from pushing the housing out of the placement plate surface and keeping the housing away from the processing environment, providing more space and making it easier to remove the housing from the device. However, the following defects still exist:

[0003] The board is fixed by a fixing rod, and then the board is bent around the fixing rod. Since the fixing rod is installed on the connecting frame, the diameter of the fixing rod is fixed, which means that the curvature of the board at the bend is fixed, making it inconvenient to change the curvature of the board at the bend. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a bending machine for processing power distribution cabinet shells, which effectively solves the problem of the inconvenience of changing the curvature of the bending part of the sheet metal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending machine for processing power distribution cabinet housings, including a mounting frame, a fixing mechanism installed inside the mounting frame, and a bending mechanism installed at the bottom of the mounting frame;

[0006] The fixing mechanism includes an L-shaped plate fixed inside the mounting frame. Inside the L-shaped plate is a lifting plate, and at the bottom of the lifting plate is a U-shaped frame. A bending roller is fixedly connected inside the U-shaped frame, and a clamping plate is fixedly installed at the top of the U-shaped frame. At the bottom of the lifting plate is a clamping groove, and the clamping plate is located inside the clamping groove. On the outside of the lifting plate is a mounting plate. On the side of the mounting plate closest to the lifting plate, there are two screws symmetrically arranged. The ends of the two screws away from the mounting plate pass through the lifting plate and the clamping plate. On the side of the lifting plate away from the mounting plate, there are two nuts symmetrically arranged. The two nuts are threaded onto the outside of the two screws.

[0007] Preferably, the bottom of the lifting plate is symmetrically provided with two positioning holes, and the top of the U-shaped frame is symmetrically fixedly installed with two positioning posts, which are located inside the two positioning holes respectively.

[0008] Preferably, two guide rods are symmetrically fixedly installed inside the L-shaped plate, and a lifting plate is movably sleeved on the outside of the two guide rods. A cylinder is fixedly installed between the top of the lifting plate and the inner top wall of the L-shaped plate.

[0009] Preferably, the bending mechanism includes a U-shaped plate fixed to the bottom of the mounting frame, two guide rods are symmetrically fixedly installed inside the U-shaped plate, a lifting plate is movably installed on the outside of the two guide rods, and a cylinder is fixedly installed between the bottom of the lifting plate and the inner bottom wall of the U-shaped plate.

[0010] Preferably, a U-shaped frame is fixedly installed on the top of the second lifting plate, a crossbar is fixedly installed inside the U-shaped frame, two sliding plates are symmetrically and movably installed on the outside of the crossbar, a U-shaped round rod is fixedly installed on the top of each of the two sliding plates, and an extrusion roller is rotatably connected to the outside of each of the two U-shaped round rods. Two guide grooves are symmetrically provided at the bottom of the mounting frame, and the two extrusion rollers are respectively located inside the two guide grooves.

[0011] Preferably, a motor is fixedly installed inside the U-shaped frame, and a bidirectional lead screw is fixedly installed on the motor. The end of the bidirectional lead screw away from the motor passes through two sliding plates and is rotatably connected to the inner wall of the U-shaped frame, and both sliding plates are threadedly connected to the bidirectional lead screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model facilitates the disassembly of the U-shaped frame through the cooperation between the card plate and the mounting plate, as well as the screw and nut, thereby facilitating the replacement of the bending roller to change the curvature of the plate bending point. Through the cooperation between the cylinder, the lifting plate and the guide rod, the bending roller moves downward to fix the plate, thereby facilitating the subsequent bending of the plate.

[0014] (2) The new type of motor and bidirectional lead screw, as well as the sliding plate and crossbar, facilitate the adjustment of the distance between the two extrusion rollers according to the diameter of the bending roller. The two extrusion rollers move upward through the cooperation between the second cylinder, the second lifting plate and the second guide rod, so that the sheet metal can be bent around the bending roller.

Plate 207, lifting plate 202 is symmetrically provided with two nuts 2013 on the side away from mounting plate 2010. The two nuts 2013 are threaded onto the outside of two screws 209 respectively. The bottom of lifting plate 202 is symmetrically provided with two positioning holes 2012. The top of U-shaped frame 203 is symmetrically fixedly installed with two positioning posts 208.
