Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to a clamping device for a plate shearing machine. Background Technique

[0002] When most existing plate shearing machines clamp and fix a plate, multiple bolts are used to squeeze multiple points on the surface of the plate to achieve the fixing effect. When the staff needs to adjust the clamping and fixing position, all the bolts need to be removed before adjustment, and the operation is relatively cumbersome. In addition, after the plate is sheared by the plate shearing machine, the sheared part will have overheating phenomenon. The high internal heat of the plate will affect both the material strength and hardness, thus unable to guarantee the product quality. Content of the Utility Model

[0003] The purpose of the utility model is to provide a clamping device for a plate shearing machine. The cold air from an external air cooler is sent into the air inlet pipe through a conveying pipe and then discharged from the air outlet slot, so that the cold air blows to the sheared part of the metal plate for cooling, alleviating the heat absorption situation during the shearing process; by sequentially starting the first cylinder and the second cylinder, the side and top surfaces of the metal plate can be clamped and fixed, realizing the positioning of metal plates with different widths and thicknesses, ensuring that the metal plate is flat and non-inclined before shearing, improving the shearing efficiency, and adopting a pneumatic method to control the movement of the clamping plate and the pressing plate, with higher efficiency compared to manual adjustment, solving the problems in the prior art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A clamping device for a plate shearing machine, including a plate shearing machine main body. A conveying roller is arranged at the front end of the shearing processing area of the plate shearing machine main body for conveying a metal plate. Both ends of the conveying roller are connected with a support plate through bearings. An fixing plate is arranged at the upper end of the support plate, and the fixing plate and the support plate are of an integral structure. A clamping plate is arranged on one side of the fixing plate close to the conveying roller, and a pressing plate is arranged above the clamping plate. An air cooling component is arranged on one side of the pressing plate. The air cooling component includes an air cooling chamber, and the air cooling chamber is fixedly connected with the pressing plate through a mounting plate. A plurality of air outlet slots are equidistantly arranged at the rear end of the air cooling chamber, and an air inlet pipe is communicated with the front end of the air cooling chamber.

[0017] A clamping device for a plate shearing machine, including a plate shearing machine main body 1. A conveying roller 3 is arranged at the front end of the shearing processing area of the plate shearing machine main body 1 for conveying a metal plate. Both ends of the conveying roller 3 are connected with a support plate 2 through bearings. An fixing plate 201 is arranged at the upper end of the support plate 2, and the fixing plate 201 and the support plate 2 are of an integral structure. A clamping plate 4 is arranged on one side of the fixing plate 201 close to the conveying roller 3. A pressing plate 5 is arranged above the clamping plate 4. An air-cooling component 6 is arranged on one side of the pressing plate 5. The air-cooling component 6 includes an air-cooling chamber, and the air-cooling chamber is fixedly connected with the pressing plate 5 through a mounting plate 603. A plurality of air outlet slots 601 are equidistantly arranged at the rear end of the air-cooling chamber. An air inlet pipe 602 is communicated with the front end of the air-cooling chamber. The mounting plate 603 facilitates the installation and disassembly of the air-cooling chamber. Cold air from an external air-cooling machine is sent into the air inlet pipe 602 through a conveying pipe and then discharged from the air outlet slots 601, so that the cold air blows to the sheared part of the metal plate for cooling, alleviating the heat absorption situation during the shearing process, avoiding the overall strength and hardness of the metal plate being affected due to excessive internal heat, and thus ensuring the product quality.

[0018] In this embodiment, a first cylinder 401 is arranged on the other side of the fixing plate 201, and the telescopic end of the first cylinder 401 is fixed to the clamping plate 4. First guide rods 402 are arranged on both the front and rear sides of the first cylinder 401, and one end of each first guide rod 402 penetrates through the fixing plate 201 and is fixed to the clamping plate 4. By driving the telescopic end of the first cylinder 401 to move, the two clamping plates 4 are driven to move towards each other to effectively clamp the metal plate.

[0019] In this embodiment, a second cylinder 501 is arranged at the upper end of the pressing plate 5, and the telescopic end of the second cylinder 501 is fixed to the clamping plate 4. Second guide rods 502 are arranged on both the front and rear sides of the second cylinder 501, and one end of each second guide rod 502 penetrates through the pressing plate 5 and is fixed to the clamping plate 4. The pressing plate 5 is in a Z shape, and a protective pad 503 is arranged at the bottom of the pressing plate 5. By driving the telescopic end of the second cylinder 501 to move, the pressing plate 5 is driven to move downward to press the metal part, realizing the positioning of the metal plate, ensuring that the metal plate is flat and without inclination before shearing, improving the shearing efficiency, and the protective pad 503 plays a role in protecting the surface of the metal plate.

[0020] Working principle: When in use, first place the metal plate on the conveying roller 3, and convey it by the conveying roller 3 to the shearing processing area of the shearing machine main body 1. This clamping device is located between the conveying roller 3 and the shearing processing area. When one end of the metal plate extends into the shearing machine main body 1, stop the movement of the conveying roller 3. Then drive the movement of its telescopic end through the first cylinder 401, and further drive the two clamping plates 4 to move towards each other to effectively clamp the metal plate. Then drive the movement of its telescopic end through the second cylinder 501, and further drive the pressing plate 5 to move downward to press the metal part, realizing the positioning of the metal plate. Then start the shearing machine main body 1 to perform shearing processing on the extended metal plate. After shearing is completed, lift the cutting tool, and send cold air through the conveying pipe to the air inlet pipe 602 by an external cold air blower, and then discharge it from the air outlet slot 601, so that the cold air blows towards the sheared part of the metal plate for cooling, and relieve the heat absorption situation during the shearing process.
