Description

Technical Field

[0001] The invention belongs to the technical field of steel plate shearing, and specifically relates to a steel plate shearing machine. Background Art

[0002] With the development of the economy, the application of steel plates is becoming more and more extensive. Steel plates are widely used in construction, automobiles, bridges and other fields. Steel plates are initially in the form of large flat plates for easy transportation. In the actual application process, steel plates need to be cut into specific sizes and shapes to facilitate subsequent practical applications and meet the requirements of various engineering and manufacturing projects.

[0003] The prior art also proposes some solutions: for example, a patent application with publication number CN111136327A discloses a shearing machine for shearing steel plates with a large thickness-to-width ratio and a shearing method using the same. An upper knife gasket and an upper rubber ring are sequentially sleeved on the outer side of the intermediate shaft of the upper knife group of the shearing machine. Similarly, a lower knife gasket and a lower rubber ring are sequentially sleeved on the outer side of the fixed shaft of the lower knife group. The upper knife gasket and the lower knife gasket are used to control and fix the distance between the two upper knives and the distance between the two lower knives to prevent the knives from offsetting when rolling and shearing the steel plate, thereby affecting the shearing size and straightness of the steel plate. The steel plate is first trimmed by the shearing machine, and then the steel plate is conventionally stripped. This can ensure that the side edges of the steel plate after trimming are straight and free of burrs, and no secondary processing is required after shearing and stripping.

[0004] After the existing steel plate shearing machine determines the cutting size, it is necessary to use a clamp to fix the steel plate to be cut on the shearing machine when shearing the steel plate to ensure that the steel plate is in a stable position during the shearing process to avoid movement or distortion. However, since the clamping of the clamp needs to be cancelled when taking out the sheared steel plate, it takes extra time to fix the steel plate with the clamp. In the case of large-scale shearing, production efficiency is affected and the risk of operational errors is increased.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figures 1 to 3 As shown, the present invention provides a technical solution: a steel plate shearing machine, comprising a base plate 1, a support frame 2 is fixedly connected to the top of the base plate 1, a telescopic cylinder 3 is fixedly connected to the bottom of the support frame 2, a shearing blade 4 is fixedly connected to the bottom of the telescopic cylinder 3, a steel plate 17 to be cut is arranged below the shearing blade 4, a conveying assembly is arranged on one side of the steel plate 17 to be cut, the conveying assembly is used to convey the steel plate 17 to be cut to a shearing position, an adjusting assembly is arranged on the other side of the steel plate 17 to be cut, the adjusting assembly is used to adjust the size required for shearing the steel plate 17 to be cut, a pushing assembly is arranged at the adjusting assembly, the pushing assembly is used to collect the sheared steel plate 17 to be cut, and a positioning assembly is arranged on one side of the shearing blade 4, the positioning assembly is used to fix the position of the steel plate 17 to be cut during shearing.

[0034] During operation: After the existing steel plate shearing machine determines the shearing size, when shearing the steel plate, it is necessary to use a clamp to fix the steel plate to be sheared on the shearing machine to ensure that the position of the steel plate is stable during the shearing process to avoid movement or distortion. However, since the clamping of the clamp needs to be cancelled when taking out the steel plate after shearing, it will take extra time to fix the steel plate by the clamp. In the case of large-scale shearing, it affects production efficiency and increases the risk of operational errors. Through the embodiment of the present scheme, during specific use, the required size of the steel plate 17 to be cut is first adjusted through the adjustment component. After the adjustment is completed, the steel plate 17 to be cut is placed in the conveying component, and the conveying component is started to align the shearing position of the steel plate 17 to be cut to the bottom of the shear blade 4, and then the telescopic cylinder 3 is started, and its output end will drive the shear blade 4 to move downward to perform the shearing operation on the steel plate 17 to be cut, and when the shear blade 4 is in the process of moving downward, the two sides of the steel plate 17 to be cut will be positioned by the positioning component. The side position is fixed, and fixing the two sides of the steel plate can ensure that the steel plate remains stable during the shearing process to prevent it from moving or shaking, thereby ensuring the accuracy and precision of the cutting. When the shearing is completed, the shear blade 4 starts to rise through the telescopic cylinder 3, and then the next part of the steel plate 17 to be cut is sheared again through the conveying component, thereby achieving the effect of continuous shearing, and when the shear blade 4 is in the process of rising, the pushing component will push the sheared steel plate out, so that the next sheared part of the steel plate 17 to be cut can be conveyed to the bottom of the shear blade 4 for shearing, and the sheared steel plate can also be collected. Through the above embodiment, the size of the steel plate shearing can be adjusted, and steel plates of different lengths can be sheared according to the specific size required. At the same time, before starting to cut, there is no need to spend extra time to fix the steel plate, so that the steel plate can be prevented from moving or shaking during the shearing process, and the steel plate can also be collected after the shearing is completed.

[0035] like Figures 4 to 5 As shown, the positioning assembly includes two receiving seats 5, the inner walls of the two receiving seats 5 are inserted with inner slide rods 6, the bottoms of the two inner slide rods 6 are fixedly connected with positioning weights 8, the bottoms of the two positioning weights 8 are flush with the bottom positions of the shear blades 4, the outsides of the two inner slide rods 6 are provided with extrusion springs 7, the two ends of the extrusion springs 7 are respectively fixedly connected to the bottom of the receiving seats 5 and the top of the positioning weights 8, and the tops of the two inner slide rods 6 are fixedly connected to limiting platforms 9.

[0036] During operation: when the telescopic cylinder 3 is started to drive the shear blade 4 to descend and is about to be sheared, when the shear blade 4 just contacts the upper surface of the steel plate 17 to be cut, the two positioning weights 8 will also contact the upper surface of the steel plate 17 to be cut, and when the shear blade 4 descends to shear, the positioning weights 8 will apply a downward squeezing force to the upper surface of the steel plate 17 to be cut. Due to the high quality of the positioning weights 8, the steel plate 17 to be cut cannot shake or deflect during shearing, and through the inner slide bar 6 and the limit table 9, when the shear blade 4 descends to shear, the positioning weights 8 The positioning weight 8 will fit tightly with the upper surface of the steel plate 17 to be cut and will not descend with the descent of the shear blade 4. When the shearing is completed and the shear blade 4 rises, the position of the positioning weight 8 is reset by squeezing the spring 7, so that the bottom of the positioning weight 8 is always kept flush with the bottom of the shear blade 4, and the positioning component can continue to be used for the next shearing. Through the above embodiment, through the positioning component, it is achieved that when the steel plate 17 to be cut is sheared, no other additional clamps are required to fix its position, thereby improving the shearing efficiency.

[0037] like Figure 6 to Figure 7 As shown, the adjustment component includes a shearing table 28, a blocking plate 18 is slidably connected to the top of the shearing table 28, sliding grooves 27 are symmetrically opened on the inner wall of the top surface of the shearing table 28, and a connecting rod 19 is symmetrically fixedly connected to the bottom of the blocking plate 18. The connecting rod 19 and the sliding groove 27 are slidably connected and adapted to each other, and a slider 20 is fixedly connected to the bottom of the two connecting rods 19. A driving component is provided on one side of the slider 20, and the driving component is used to drive the slider 20 to slide.

[0038] When working: starting the driving component will drive the two sliders 20 to slide. When the sliders 20 slide, the blocking plate 18 will be driven to slide through the connecting rod 19. Therefore, the blocking plate 18 can slide on the upper surface of the shearing table 28. When the conveying component conveys the steel plate 17 to be cut, one side of the steel plate 17 to be cut will be attached to one side of the blocking plate 18. Since the shearing blade 4 is located on one side of the shearing table 28, its horizontal position is fixed. By changing the horizontal position of the blocking plate 18 on the shearing table 28, the length of the sheared steel plate can be adjusted. Through the above embodiment, the length of the sheared steel plate can be adjusted to meet the changes in the requirements of different steel plate sizes and improve the adaptability and flexibility of production.

[0039] like Figure 6 to Figure 7 As shown, the driving assembly includes two fixed seats 21, and the two fixed seats 21 are fixedly installed on the lower inner side of the shearing table 28. The inner walls of the two fixed seats 21 are rotatably connected with threaded rods 22. The outer walls of the two threaded rods 22 are respectively threadedly connected to the inner walls of the two connecting rods 19, and the two sliders 20 are respectively slidably connected to the inner walls of the two fixed seats 21.

[0040] During operation: when the threaded rod 22 rotates, since the slider 20 is threadedly connected to the threaded rod 22, and the slider 20 is slidably connected in the inner wall of the fixed seat 21, the rotation of the threaded rod 22 will cause the slider 20 to move, and the blocking plate 18 is driven to move through the connecting rod 19. Through the above embodiment, the blocking plate 18 is moved back and forth, so that the length of the shear steel plate can be adjusted.

[0041] like Figure 6 to Figure 7 As shown, one end of the two threaded rods 22 is fixedly connected to a transmission ring 23, and a transmission belt 26 is transmission-connected between the outer walls of the two transmission rings 23. A motor 24 is fixedly installed on the inner side below the shearing table 28, and the output shaft of the motor 24 is fixedly connected to a transmission disk 25. The outer wall of the transmission disk 25 is transmission-connected to the inner side of the transmission belt 26.

[0042] During operation: start the motor 24, and its output shaft will drive the transmission disc 25 to rotate. When the transmission disc 25 rotates, it will drive the two transmission rings 23 to rotate through the transmission belt 26. When the transmission ring 23 rotates, it will drive the threaded rod 22 to rotate. Through the above embodiment, the two threaded rods 22 are driven to rotate, thereby adjusting the position of the blocking plate 18.

[0043] like Figures 2 to 3 As shown, the conveying assembly includes a conveying platform 10, a plurality of clamping seats 11 are fixedly connected to the top of the conveying platform 10, the inner walls of the plurality of clamping seats 11 are rotatably connected to conveying cylinders 12, the outer walls of the plurality of conveying cylinders 12 are fixedly connected to transmission rings 13, and a transmission belt 14 is transmission-connected between the outer walls of the plurality of transmission rings 13, and a motor 15 is fixedly installed on one side of the conveying platform 10, and the output shaft of the motor 15 is fixedly connected to one end of one of the conveying cylinders 12.

[0044] During operation: the steel plate 17 to be cut is placed directly above the conveying cylinder 12, and by starting the motor 15, its output shaft will drive one of the conveying cylinders 12 to rotate, and through the transmission ring 13 and the transmission belt 14, multiple conveying cylinders 12 are rotated at the same time. When multiple conveying cylinders 12 rotate, the steel plate 17 to be cut above can be conveyed. Through the above embodiment, the effect of conveying the steel plate 17 to be cut to the bottom of the shear blade 4 and the blocking plate 18 is achieved.

[0045] like Figures 2 to 3 As shown, the limiting plates 16 are symmetrically slidably connected between the two ends of the top of the plurality of clamping seats 11, and one side of the two limiting plates 16 is always in contact with the two sides of the steel plate 17 to be cut.

[0046] During operation: when the steel plate 17 to be cut is being transported, the limiting plate 16 can limit the two sides of the steel plate 17 to prevent the position of the steel plate 17 to be cut from being offset due to other factors during the transportation process, resulting in inconsistent shapes of the sheared steel plates.

[0047] like Figures 8 to 9 As shown, the pushing assembly includes a movable plate 34, which is slidably connected to the top of the shearing table 28, and a telescopic cylinder 2 38 is provided on one side of the movable plate 34. The output end of the telescopic cylinder 2 38 is fixedly connected to a push plate 35, and the output end of the telescopic cylinder 2 38 is plugged into the interior of the movable plate 34. A control button 39 is fixedly installed on the bottom side of the support frame 2, and the control button 39 is used to control the start of the telescopic cylinder 2 38.

[0048] During operation: when the shear blade 4 completes shearing and rises to the highest position, the limit platform 9 will touch the control button 39, and the control button 39 will start the telescopic cylinder 2 38. The output end of the telescopic cylinder 2 38 will drive the push plate 35 to move, and push out the steel plate that has been sheared above the blocking plate 18. Through the above embodiment, the effect of collecting the sheared steel plate is achieved, and it is also convenient for the remaining steel plates 17 to be cut to continue to be transported to one side of the blocking plate 18 for further shearing.

[0049] like Figures 8 to 9 As shown, tension springs 33 are fixedly connected to both sides of the movable plate 34, a fixed block 32 is fixedly installed above one of the clamping seats 11, and the other two ends of the two tension springs 33 are fixedly connected to one side of the blocking plate 18 and one side of the fixed block 32 respectively, and a slider 2 37 is fixedly connected to the bottom of the movable plate 34, and a slide groove 36 is provided on the inner wall of the top surface of the shearing table 28, and the slider 2 37 is slidably connected to the slide groove 36 and is adapted to each other.

[0050] During operation: when the blocking plate 18 is adjusted, the movable plate 34 is caused to slide by the tension spring 33, and the sliding position of the movable plate 34 is limited by the slider 2 37 and the slide groove 36. Through the sliding of the movable plate 34, the telescopic cylinder 2 38 and the movable plate 34 can always be aligned with the center of one side of the sheared steel plate, so that for any size of steel plate sheared out, the movable plate 34 can be aligned with the center of the steel plate and pushed out. Aligning with the center of the steel plate and pushing it ensures that the steel plate will not deviate when being pushed out, preventing it from sliding and being collected according to the set route.

[0051] like Figure 1 to Figure 2 As shown, an inclined slide 29 is opened on one side of the shearing table 28, a slide plate 30 is fixedly connected to one side of the inclined slide 29, a material receiving box 31 is arranged below the slide plate 30, and the material receiving box 31 is fixedly installed just above the bottom plate 1.

[0052] During operation: when the sheared steel plate is pushed out, it will slide out along the inclined slide 29, and then slide into the material receiving box 31 through the sliding plate 30, so as to collect the steel plate after shearing.

[0053] Working process: first start the motor 24, and its output shaft will drive the transmission disk 25 to rotate. When the transmission disk 25 rotates, it will drive the two transmission rings 23 to rotate through the transmission belt 26. When the transmission ring 23 rotates, it will drive the threaded rod 22 to rotate. When the threaded rod 22 rotates, since the slider 20 is threadedly connected to the threaded rod 22, and the slider 20 is slidably connected in the inner wall of the fixed seat 21, the rotation of the threaded rod 22 will cause the slider 20 to move, and drive the blocking plate 18 to move through the connecting rod 19. The blocking plate 18 can slide on the upper surface of the shearing table 28. When the conveying assembly conveys the steel plate 17 to be cut, one side of the steel plate 17 to be cut will fit onto one side of the blocking plate 18, and since the shear blade 4 is located on one side of the shearing table 28, its horizontal position is fixed. The length of the sheared steel plate can be adjusted by changing the horizontal position of the blocking plate 18 on the shearing table 28.

[0054] Secondly, the steel plate 17 to be cut is placed directly above the conveying cylinder 12, and by starting the motor 15, its output shaft will drive one of the conveying cylinders 12 to rotate, and through the transmission ring 13 and the transmission belt 14, multiple conveying cylinders 12 are rotated at the same time. When multiple conveying cylinders 12 rotate, the steel plate 17 to be cut on the top can be conveyed. Through the limiting plate 16, when the steel plate 17 to be cut is conveyed, the two sides of the steel plate 17 to be cut can be limited to prevent the position of the steel plate 17 to be cut from being offset due to other factors during the conveying process.

[0055] When the shear blade 4 is lifted up, the position of the positioning weight 8 is reset by the extrusion spring 7, so that the bottom of the positioning weight 8 is always kept flush with the bottom of the shear blade 4, and the positioning component can continue to be used for the next shearing.

[0056] Finally, after the shearing is completed, the shear blade 4 starts to rise through the telescopic cylinder 1 3. When the shear blade 4 completes the shearing and rises to the highest position, the limit table 9 touches the control button 39, and the control button 39 starts the telescopic cylinder 2 38. The output end of the telescopic cylinder 2 38 drives the push plate 35 to move, and pushes out the steel plate that has been sheared above the blocking plate 18. When the blocking plate 18 is adjusted, the movable plate 34 slides through the tension spring 33, and the movable plate 34 slides through the slider 2 37 and the slide groove 36. The position is limited, and through the sliding of the movable plate 34, the telescopic cylinder 2 38 and the movable plate 34 can always be aligned with the center of one side of the sheared steel plate, so that for any size of the sheared steel plate, the movable plate 34 can be aligned with the center of the steel plate and push it out. The push is aligned with the center of the steel plate so that the steel plate will not deviate when it is pushed out. When the sheared steel plate is pushed out, it will slide out along the inclined slide 29, and will slide into the material collection box 31 through the landslide plate 30, thereby realizing the collection of the steel plate after shearing.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention.
