Description

Technical Field

[0001] This utility model belongs to the field of metal processing technology, specifically a steel plate cutting device. Background Technology

[0002] Metal cutting is an important processing step in the production and manufacturing of metal parts. Specifically, it refers to the removal of material from metal materials using cutting tools or cutting instruments to achieve the desired shape, size, and surface texture. The cutting process can be carried out on various machine tools and equipment.

[0003] The basic principle of the cutting process is to use the relative movement between the tool and the workpiece to make the cutting edge of the tool contact the surface of the workpiece and apply cutting force, so that the tool removes excess material from the workpiece. After the cutting is completed, the workpiece is cleaned, deburred, and rust-proofed to improve the service life of the workpiece. However, when it is necessary to use a cutting device to cut texture on the surface of a steel plate, a support needs to be placed on the back of the steel plate to prevent the steel plate from bending when it is cut by the tool, resulting in insufficient cutting depth. However, if a support is placed, there will be a lot of friction between the steel plate and the support, which makes it difficult to adjust the position of the steel plate.

[0004] Therefore, this utility model provides a steel plate cutting device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A steel plate cutting device of this utility model includes a processing table housing; a support platform is fixedly connected to the middle of the processing table housing; multiple through holes are opened in the middle of the support platform; a connecting column is installed inside the processing table housing; a support frame is fixedly connected to the top of the connecting column; multiple top columns are fixedly connected to the top of the support frame; the multiple top columns are slidably connected to the middle of the multiple through holes; a ball bearing is rotatably connected to the top of the top column; a slot is opened on the side wall of the connecting column; and the bottom inner side of the processing table housing is fixedly connected to... There is a pair of support rods; a lifting plate is rotatably connected to the middle of the pair of support rods; the lifting plate is lever-shaped to the support rods; one end of the lifting plate extends into the interior of the slot; a through groove is opened on the side wall of the machining table housing; the middle of the lifting plate passes through the through groove; with the above structure, the steel plate can be supported when cutting the steel plate, reducing the decrease in cutting accuracy caused by the downward bending of the middle of the steel plate; when it is necessary to adjust the position of the steel plate, multiple ball bearings are used to lift the through hole, reducing the friction force on the steel plate, thereby facilitating the position adjustment of the steel plate.

[0007] Preferably, the support frame has an internal cavity; the top column has an internal through-tube; the through-tube extends through the top and bottom of the top column; multiple extension tubes are fixedly connected to the internal cavity; the multiple extension tubes are respectively connected to the multiple through-tubes; multiple liquid inlet grooves are formed at the bottom end of the extension tubes; a pair of elastic hollow bladders are fixedly connected to the top of the support frame; the elastic hollow bladders are connected to the cavity; a liquid injection pipe is fixedly connected to the side wall of the support frame; the liquid injection pipe is connected to the cavity, and the other end of the liquid injection pipe extends to the outside of the processing table housing; with the above structure, the occurrence of jamming between the ball and the top column can be reduced, thereby reducing the occurrence of friction damage to the bottom of the steel plate caused by the ball being unable to rotate normally due to jamming between the ball and the top column.

[0008] Preferably, the top of the lifting plate is provided with a sliding groove; the sliding groove is located at the end of the lifting plate away from the connecting column; a first extension plate and a second extension plate are slidably connected in sequence in the middle of the sliding groove; with the above structure, some heavier steel plates can be lifted by extending the length of the lifting plate, which serves as the lever force-generating end, thereby reducing the force required.

[0009] Preferably, a pair of springs are fixedly connected to the bottom inner side of the processing table housing; a top plate is fixedly connected to the top of the pair of springs; the top plate is located below the connecting column; through the above structure, the collision between the bottom of the connecting column and the bottom of the processing table housing is reduced, thereby reducing the occurrence of loosening of the components of the device due to vibration during impact.

[0010] Preferably, a pair of slide rails are fixedly connected to the side wall of the processing table housing; a slide rod is slidably connected to the middle of the pair of slide rails; through the above structure, the steel plate can always be kept in a raised state, thereby facilitating the operator to adjust the position of the steel plate.

[0011] Preferably, a first magnet is fixed to one end of the second extension plate near the lifting plate; a second magnet is fixed to the side of the slide away from the second extension plate; the first magnet and the second magnet are attracted to each other; the above structure prevents the second extension plate and the first extension plate from sliding apart due to equipment vibration, thereby hindering the operator's movement.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The steel plate cutting device of this utility model involves pressing down one end of a lifting plate, which, under the action of a lever, lifts the other end of the lifting plate upward. This causes multiple ball bearings to contact the bottom of the steel plate and lift it up, allowing for position adjustment. At this point, the steel plate experiences minimal resistance. After adjustment, the foot is lifted, and multiple top columns descend through the through-hole, causing the steel plate to fall back onto the top of the support platform, where it can then be cut. This structure supports the steel plate during cutting, reducing the decrease in cutting accuracy caused by the downward bending of the steel plate in the middle. When position adjustment is needed, multiple ball bearings lift the through-hole, reducing friction on the steel plate and facilitating position adjustment.

[0014] 2. The steel plate cutting device of this utility model injects lubricating liquid into the cavity through an injection pipe, and then blocks the end of the injection pipe. When the support frame rises, the gas inside the elastic hollow bladder is squeezed into the cavity, causing the pressure inside the cavity to rise and forcing the lubricating liquid into the connection between the top column and the ball. Through the above structure, the occurrence of jamming between the ball and the top column can be reduced, thereby reducing the occurrence of friction damage to the bottom of the steel plate caused by the ball being unable to rotate normally due to jamming between the ball and the top column.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 3 As shown in the embodiment of this utility model, a steel plate cutting device includes a processing table housing 1; a support platform 12 is fixedly connected to the middle of the processing table housing 1; a plurality of through holes 13 are opened in the middle of the support platform 12; a connecting column 14 is installed inside the processing table housing 1; a support frame 15 is fixedly connected to the top of the connecting column 14; a plurality of top columns 16 are fixedly connected to the top of the support frame 15; the plurality of top columns 16 are slidably connected to the middle of the plurality of through holes 13; a ball bearing 17 is rotatably connected to the top of the top column 16; and a retaining device is opened on the side wall of the connecting column 14. The machining table housing 1 has a slot 18; a pair of support rods 19 are fixedly connected to the bottom inner side of the machining table housing 1; a lifting plate 110 is rotatably connected to the middle of the pair of support rods 19; the lifting plate 110 is lever-equipped with the support rods 19; one end of the lifting plate 110 extends into the interior of the slot 18; a through slot 111 is provided on the side wall of the machining table housing 1; the middle of the lifting plate 110 passes through the through slot 111; during operation, the steel plate is placed on top of the support platform 12, and when the position of the steel plate needs to be adjusted, the lifting plate 110 is positioned outside the machining table housing 1. Stepping down on one end causes the other end of the lifting plate 110 to rise under the leverage, which in turn lifts the connecting column 14 and the support frame 15. This causes multiple top columns 16 to slide upward along the through hole 13. At this time, multiple ball bearings 17 will contact the bottom of the steel plate and lift it up. Then, the position of the steel plate is adjusted. As the steel plate moves, the ball bearings 17 are driven by the steel plate to roll on the top of the top column 16, thus creating a rolling fit between the steel plate and the ball bearings 17. This ensures that the steel plate experiences very little resistance when moving. After the adjustment is completed, the foot is lifted. The top post 16 descends along the through hole 13, causing the steel plate to fall back onto the top of the support platform 12. At this point, the steel plate can be cut. During cutting, the support platform 12 supports the steel plate to prevent it from bending downwards in the middle. Through the above structure, the steel plate can be supported during cutting, reducing the decrease in cutting accuracy caused by the downward bending of the middle of the steel plate. When it is necessary to adjust the position of the steel plate, multiple balls 17 are used to lift the through hole 13, reducing the friction on the steel plate and facilitating the position adjustment of the steel plate.

[0023] like Figures 1 to 3As shown, the support frame 15 has a cavity 2 inside; the top column 16 has a through pipe 21 inside; the through pipe 21 passes through the top and bottom of the top column 16; multiple extension pipes 22 are fixedly connected inside the cavity 2; the multiple extension pipes 22 are respectively connected to the multiple through pipes 21; multiple liquid inlet grooves 23 are opened at the bottom end of the extension pipes 22; a pair of elastic hollow bladders 24 are fixedly connected to the top of the support frame 15; the elastic hollow bladders 24 are connected to the cavity 2; a liquid injection pipe 25 is fixedly connected to the side wall of the support frame 15; the liquid injection pipe 25 is connected to the cavity 2, and the other end of the liquid injection pipe 25 extends to the outside of the processing table housing 1; during operation, lubricating liquid is injected into the cavity 2 through the liquid injection pipe 25, and then... By blocking the end of the injection tube 25, when the support frame 15 rises, the elastic hollow bladder 24 is squeezed by the support frame 15 and the through hole 13, thereby squeezing the gas inside the elastic hollow bladder 24 into the cavity 2, causing the air pressure inside the cavity 2 to rise. The lubricating liquid inside the cavity 2 is then squeezed into the connection between the top column 16 and the ball 17 through the inlet groove 23 and the through pipe 21, lubricating the connection between the top column 16 and the ball 17. This allows the ball 17 to roll flexibly on the top of the top column 16. Through the above structure, the occurrence of jamming between the ball 17 and the top column 16 can be reduced, thereby reducing the occurrence of friction damage to the bottom of the steel plate caused by the ball 17 being unable to rotate normally due to jamming between the ball 17 and the top column 16.

[0024] like Figures 1 to 4 As shown, a groove 3 is provided on the top of the lifting plate 110; the groove 3 is located at the end of the lifting plate 110 away from the connecting column 14; a first extension plate 31 and a second extension plate 32 are slidably connected in sequence in the middle of the groove 3; during operation, when the steel plate above the support platform 12 has a large mass, the first extension plate 31 and the second extension plate 32 can slide out from the inside of the groove 3 in sequence, thereby extending the length of the lifting plate 110, and thus, under the action of the lever, the heavier steel plate can be lifted with less effort. Through the above structure, by extending the length of the lifting plate 110, which is the lever's force-generating end, some heavier steel plates can be lifted, reducing the force required.

[0025] like Figures 1 to 4 As shown, a pair of springs 4 are fixedly connected to the bottom inner side of the processing table housing 1; a top plate 41 is fixedly connected to the top of the pair of springs 4; the top plate 41 is located below the connecting column 14; during operation, when the connecting column 14 falls, the bottom of the connecting column 14 will land on the top of the top plate 41, and then the kinetic energy of the falling connecting column 14 will be absorbed by the springs 4, thereby reducing the collision between the bottom of the connecting column 14 and the bottom of the processing table housing 1, thereby reducing the occurrence of loosening of the components of the device due to vibration during impact.

[0026] like Figures 1 to 2As shown, a pair of slide rails 5 are fixedly connected to the side wall of the processing table housing 1; a slide rod 51 is slidably connected to the middle of the pair of slide rails 5; during operation, after the lifting plate 110 is stepped down, the slide rod 51 can be slid in the middle of the slide rail 5 to the top of the lifting plate 110, and then the foot is released. The lifting plate 110 will be blocked by the bottom end of the slide rod 51, so it cannot be reset, and the steel plate can always be kept in the lifted state, which makes it convenient for the operator to adjust the position of the steel plate.

[0027] like Figures 1 to 4 As shown, a first magnet 6 is fixedly connected to one end of the second extension plate 32 near the lifting plate 110; a second magnet 61 is fixedly connected to the side of the slide groove 3 away from the second extension plate 32; the first magnet 6 and the second magnet 61 are attracted to each other; during operation, after the first extension plate 31 and the second extension plate 32 are retracted, the first magnet 6 will attract the second magnet 61, so that the second extension plate 32 and the first extension plate 31 will not slide apart due to the vibration of the equipment, thereby hindering the operator's movement.

[0028] like Figure 4 As shown, the top of the second extension plate 32 is provided with a plurality of anti-slip protrusions 7; the plurality of anti-slip protrusions 7 are evenly arranged on the top of the second extension plate 32; during operation, the operator places his foot on the top of the second extension plate 32 and then exerts force in a direction away from the processing table housing 1. Through the friction between the foot and the second extension plate 32, the second extension plate 32 and the first extension plate 31 can be slid out from the inside of the slide groove 3. The anti-slip protrusions 7 can increase the friction between the bottom of the foot and the second extension plate 32 and reduce the occurrence of slippage.

[0029] During operation, the steel plate is placed on top of the support platform 12. When the position of the steel plate needs to be adjusted, the end of the lifting plate 110 located outside the processing table housing 1 is pressed down. Under the action of the lever, the other end of the lifting plate 110 will be lifted upward, thereby driving the connecting column 14 and the support frame 15 to rise. This causes multiple top columns 16 to slide upward along the through hole 13. At this time, multiple balls 17 will contact the bottom of the steel plate and lift the steel plate. Then, the position of the steel plate is adjusted. When the steel plate moves, the balls 17 will be driven by the steel plate to roll on the top of the top columns 16, thereby making the steel plate and the support frame 15 move upward. The balls 17 are in a rolling fit, so that the steel plate experiences very little resistance when moving. After adjustment, the foot is lifted, and multiple top columns 16 will descend along the through hole 13, causing the steel plate to fall back onto the top of the support platform 12. At this point, the steel plate can be cut. During cutting, the support platform 12 will support the steel plate to prevent it from bending downwards in the middle during cutting. Lubricating liquid is injected into the cavity 2 through the injection pipe 25, and then the end of the injection pipe 25 is blocked. When the support frame 15 rises, the elastic hollow bladder 24 is squeezed by the support frame 15 and the through hole 13, thereby compressing the elastic hollow bladder 24. 4. Internal gas is forced into the cavity 2, increasing the internal air pressure. This forces the lubricating liquid inside the cavity 2 through the inlet groove 23 and the through pipe 21 into the connection between the top column 16 and the ball bearing 17, lubricating the connection and allowing the ball bearing 17 to roll flexibly on top of the top column 16. When the steel plate above the support platform 12 is heavy, the first extension plate 31 and the second extension plate 32 can slide out sequentially from the inside of the slide groove 3, extending the length of the lifting plate 110. This allows for easier lifting of the heavier steel plate under the leverage effect. (The last sentence appears to be incomplete and possibly refers to a different topic.) When the connecting column 14 falls, the bottom of the connecting column 14 will land on the top of the top plate 41. Then the kinetic energy of the falling connecting column 14 will be absorbed by the spring 4. After the lifting plate 110 is stepped down, the slide bar 51 can be slid in the middle of the slide rail 5 to the top of the lifting plate 110. Then release the foot, and the lifting plate 110 will be blocked by the bottom end of the slide bar 51, so that it cannot be reset, and the steel plate can always be kept in the lifted state. After the first extension plate 31 and the second extension plate 32 are retracted, the first magnet 6 will attract the second magnet 61, so that the second extension plate 32 and the first extension plate 31 will not slide apart due to the vibration of the equipment.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
