Description

Technical Field

[0001] This utility model relates to the field of shearing machines, and more particularly to a pneumatic shearing machine. Background Technology

[0002] A pneumatic shearing machine is a mechanical device that uses air pressure to drive and process sheet metal through shearing action. It is widely used in industries such as metal processing, automobile manufacturing, construction and decoration, and machinery manufacturing. It is one of the key pieces of equipment in the process of metal sheet processing. According to the different shearing methods, pneumatic shearing machines can be divided into two main categories: swing beam shearing machines and gantry shearing machines. Existing pneumatic shearing machines have simple mechanisms, poor cutter reset ability, and poor fixation at the shearing edge of the sheet metal during shearing, which makes the cut edge of the sheet metal easy to deform and affects the quality of the sheet metal.

[0003] Therefore, it is necessary to provide a pneumatic shearing machine to solve the above-mentioned technical problems. Utility Model Content

[0004] This utility model provides a pneumatic shearing machine that solves the problems of existing pneumatic shearing machines having a simple mechanism, poor cutter reset capability, and poor fixation at the cut edge of the board during shearing, which leads to easy deformation of the cut edge and affects the quality of the board.

[0005] To solve the above-mentioned technical problems, this utility model provides a pneumatic shearing machine, including a first workbench and a second workbench. A hydraulic rod is fixed on the first workbench by a support plate. A connecting plate is fixed to the output end of the hydraulic rod, and a top plate is fixed to the top of the connecting plate. A connecting piece is fixed to the bottom of the top plate by a cylinder, and a cutting blade is installed on the connecting piece.

[0006] A limiting plate is fixed on the connecting plate, and a first spring is fixed between the top of the limiting plate and the connecting member. A pressure plate is fixed to the bottom of the connecting member by a second spring.

[0007] Preferably, the support plate is provided with buttons.

[0008] Preferably, the connector is fixed to the cutter by bolts.

[0009] Preferably, the cylinder is provided with an air pipe.

[0010] Preferably, both the bottom of the first workbench and the second workbench are fixed with support legs.

[0011] Preferably, the output end of the hydraulic rod is fixed to the connecting plate via a connecting block.

[0012] Compared with related technologies, the pneumatic shearing machine provided by this utility model has the following advantages:

[0013] This utility model provides a pneumatic shearing machine. A cylinder is activated by a button, causing the cutter on the connecting piece to move downwards. Simultaneously, a second spring at the bottom of the connecting piece drives a pressure plate to press and fix the cutting edge of the sheet metal. The cutter then cuts the sheet metal. When the cylinder stops, a first spring causes the cutter on the connecting piece to quickly return to its original position. This invention solves the problems of existing pneumatic shearing machines, such as a simple mechanism, poor cutter return capability, and poor fixation at the cut edge of the sheet metal during shearing, leading to easy deformation of the cut edge and affecting the quality of the sheet metal.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1-2 As shown, in order to solve the above-mentioned technical problems, the present invention provides a pneumatic shearing machine, including a first workbench 1 and a second workbench 2. The plate is placed on the first workbench 1 and the second workbench 2 and the position is adjusted. A hydraulic rod 4 is fixed on the first workbench 1 by a support plate 3. A connecting plate 5 is fixed to the output end of the hydraulic rod 4. A top plate 6 is fixed to the top of the connecting plate 5. A connecting piece 8 is fixed to the bottom of the top plate 6 by a cylinder 7. A cutter 9 is installed on the connecting piece 8.

[0019] The connecting plate 5 of this utility model is fixed with a limiting plate 10, and a first spring 11 is fixed between the top of the limiting plate 10 and the connecting member 8. The first spring 11 drives the cutter 9 on the connecting member 8 to quickly reset. The bottom of the connecting member 8 is fixed with a pressure plate 13 by a second spring 12. The cylinder 7 is activated to drive the cutter 9 on the connecting member 8 downward.
