Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal processing, and particularly relates to a feeding device for cutting metal plates. Background Art

[0002] During the production process of electrical cabinets, it is necessary to cut large metal plates into multiple small rectangular plates, and then form the electrical cabinet housing through processes such as punching, bending, welding, and assembly. Currently, when cutting metal plates, smaller plates can be manually transferred to the cutting machine bed for cutting, while larger plates need to be lifted by a crane and then transferred above the cutting machine bed. The feeding efficiency of these two methods for plates is relatively low, and there are certain safety hazards, so it is necessary to make improvements. Content of the Utility Model

[0003] In order to solve the above-mentioned defects of the prior art, the present application provides a feeding device for cutting metal plates, which can automatically push the metal plate above the cutting machine bed, effectively improving the processing efficiency.

[0006] A fixed frame, in which two diagonal steel bars are vertically arranged for accommodating stacked metal plates, and the height of the bottom of the diagonal steel bar matches the height of the bottom of the fixed frame;

[0007] Two groups of first support rollers are arranged at the bottom of the fixed frame, the distance between the first support roller and the support frame matches the thickness of the metal plate, and the axial direction of the first support roller is parallel to the length direction of the fixed frame;

[0008] A pushing mechanism is arranged between the two groups of first support rollers, and the pushing direction of the pushing end of the pushing mechanism is parallel to the width direction of the fixed frame, and is used to push the metal plate that has fallen onto the first support roller.

The axial direction of the second support rollers is parallel to the length direction of the fixed frame, and the top height of the second support rollers matches the top height of the first support rods.

[0012] Further, one end of the support frame is rotatably connected between a pair of vertical plates, and the other end of the support frame is hinged to the telescopic end of a cylinder. The fixed end of the cylinder is hinged to a fixed seat. When the telescopic end of the cylinder is fully extended, the support frame is parallel to the fixed frame.

Detailed Embodiments

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following describes the embodiments of the present utility model in detail with reference to the drawings. However, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] The embodiment of the present application provides a metal plate cutting and loading device, as Figures 1-4 shown, including a fixed frame 1, a first support roller 3, a pushing mechanism, etc.

[0023] Specifically, two diagonal steel bars 2 are vertically arranged inside the fixed frame 1 for accommodating stacked metal plates. The height of the bottom of the diagonal steel bar 2 matches the height of the bottom of the fixed frame 1. Two groups of first support rollers 3 are arranged at the bottom of the fixed frame 1. The distance between the first support roller 3 and the support frame 5 matches the thickness of the metal plate. The axial direction of the first support roller 3 is parallel to the length direction of the fixed frame 1. A pushing mechanism is arranged between the two groups of first support rollers 3. The pushing direction of the pushing end of the pushing mechanism is parallel to the width direction of the fixed frame 1 and is used to push the metal plate that has landed on the first support roller 3.

[0024] During actual use, place the device on one side of the cutting machine tool. Put multiple metal plates into the two diagonal steel bars 2. The bottommost metal plate will land above the first support roller 3. At this time, control the pushing end of the pushing mechanism to push the bottommost metal plate towards the cutting machine tool, and the plate can be pushed above the cutting machine tool.

[0025] Specifically, refer to Figure 1 、 Figure 2 、 Figure 4 The pushing mechanism includes a driving motor 4 and multiple driving wheels 401. The multiple driving wheels 401 are rotatably arranged between a pair of vertical plates 402 along the width direction of the fixed frame 1, and the multiple driving wheels 401 are rotatably engaged with a driving belt 403 or a driving chain with a push block 404 arranged outside. When the push block 404 rotates above the driving wheel 401, the height of the top of the push block 404 is lower than the height of the fixed frame 1 and higher than the height of the first support roller 3. One of the driving wheels 401 is connected to the output shaft of the driving motor 4. When it is necessary to push out the bottommost metal plate, control the driving motor 4 to drive the driving belt 403 or the driving chain to rotate, and then drive the push block 404 to rotate, and the metal plate can be pushed out to complete the feeding. More specifically, refer to Figure 1 At the bottom of both ends of the fixed frame 1, a support plate 101 is provided. One end of the two groups of first support rollers 3 is respectively rotatably connected to a pair of vertical plates 402, and the other end of the two groups of first support rollers 3 is respectively rotatably connected to the two support plates 101. After the driving belt 403 or the driving chain drives the push block 404 to push out the metal plate, the push block 404 will rotate below the driving wheel 401 and then return to the initial position. Compared with directly using an electric push cylinder or an oil cylinder as the pushing mechanism, there will be no friction with the next metal plate inside the two diagonal steel bars 2 when controlling the pushing end to retract.

[0026] Preferably, refer to Figure 3 、 Figure 4, one end of a pair of vertical plates 402 is connected to a support frame 5. A plurality of second support rollers 501 are arranged inside the support frame 5. The axial direction of the second support rollers 501 is parallel to the length direction of the fixed frame 1, and the top height of the second support rollers 501 matches the top height of the first support rod. When the metal plate is pushed out by the push block 404, the first part pushed out can be supported by the second support rollers 501, avoiding the metal plate bending downward due to gravity during the pushing process, which affects the stability of the metal plate during the pushing process. Specifically, one end of the support frame 5 is rotatably connected between a pair of vertical plates 402, and the other end of the support frame 5 is hinged to the telescopic end of a cylinder 6. The fixed end of the cylinder 6 is hinged to a fixed seat 7, and the fixed seat 7 can be fixed to the ground. When the telescopic end of the cylinder 6 is fully extended, the support frame 5 is parallel to the fixed frame 1. When the telescopic end of the cylinder 6 retracts, the other end of the support frame 5 rotates downward. After the metal plate is fully pushed out, the telescopic end of the cylinder 6 can be controlled to retract, so that the metal plate slides downward to above the cutting mechanism.

[0027] The above are only some embodiments listed in this application and are not used to limit this application.
