Technical Field

[0001] The utility model relates to a plate shearing machine, in particular to an efficient plate shearing machine for steel shovel production applied to the field of steel shovel production and processing. Background Technique

[0002] A shovel belongs to a commonly used tool for work such as shoveling soil and digging pits. Its front end is provided with an iron shovel head, and the rear end is provided with a wooden long handle. Moreover, the front end of the shovel head is mostly flat or semi-circular. Shovels are indispensable important tools in engineering construction and agricultural labor. During the production process of steel shovels, steel plates need to be cut into sheet materials according to the sizes of the steel shovels to be produced.

[0003] The specification of Chinese Patent CN218799444U discloses a large-panel steel plate shearing machine. The purpose of this utility model is to provide a large-panel steel plate shearing machine that can automatically push materials into the shearing machine, which is not only safe and reliable but also can save manpower.

[0004] However, in the actual application process, there is no limit component in the existing plate shearing machine, which makes the steel plate prone to shift due to the thrust and cutting force during the shearing process, resulting in errors in the shearing size of the steel plate, cutting the steel plate waste, and thus increasing the production cost of steel shovels. Content of the Utility Model

[0005] Aiming at the above-mentioned existing technology, the technical problem to be solved by this utility model is that there is no limit component in the existing plate shearing machine, which makes the steel plate prone to shift due to the thrust and cutting force during the shearing process, resulting in errors in the shearing size of the steel plate, cutting the steel plate waste, and thus increasing the production cost of steel shovels.

[0006] To solve the above problems, this utility model provides an efficient plate shearing machine for steel shovel production, including a workbench. A plurality of cutting grooves are dug at the upper end of the workbench. A plurality of mounting rods are fixedly connected to the lower end of the workbench. A double-shaft motor is fixedly connected to the lower end of the mounting rod. Both output ends of the double-shaft motor are fixedly connected with shearing knives. One end of the shearing knife close to the workbench penetrates through the cutting groove. Support bars are fixedly connected to both the front and rear ends of the workbench. An electric track is fixedly connected to the upper end of the support bar. A fixing plate is placed on the upper end of the workbench. The fixing plate is located on the right side of the shearing knife. A slider is slidably connected in the electric track. A positioning rod is fixedly connected to the upper end of the slider. One end of the positioning rod away from the slider is fixedly connected to one end of the fixing plate close to the shearing knife. A plurality of accommodating grooves corresponding to the plurality of cutting grooves respectively are dug at the upper end of the fixing plate. A baffle and a plurality of L-shaped plates located on the right side of the baffle are fixedly connected to the upper end of the fixing plate. The baffle is located on the right side of the accommodating groove. A pressing plate is arranged at the lower end of the L-shaped plate. A screw rod and two limiting rods are arranged at the upper end of the L-shaped plate. The lower end of the screw rod threadedly penetrates through the L-shaped plate and is rotatably connected to the upper end of the pressing plate. The lower end of the limiting rod movably penetrates through the L-shaped plate and is fixedly connected to the upper end of the pressing plate.

[0007] In the above-mentioned high-efficiency plate shearing machine for steel shovel production, the steel plate can be automatically pushed forward and sheared into multiple plate materials of the same width. During the shearing process, the upper end of the steel plate can be pressed and fixed at multiple places, effectively reducing the situation of the steel plate shifting and shaking during shearing, thereby reducing the shearing error of the steel plate and improving the cutting efficiency and accuracy.

[0008] As a further improvement of the present application, a protective cover is fixedly connected to the upper ends of the two support bars, and the protective cover is located directly above the multiple shearing knives.

[0009] As a further improvement of the present application, the distance between two adjacent cutting grooves is the same as the distance between the outermost cutting groove and the front and rear ends of the workbench. The number of both the dual-axis motor and the cutting grooves is an even number, and the number of the dual-axis motor is half of the number of the cutting grooves.

[0010] As a further improvement of the present application, the number of L-shaped plates is one more than the number of accommodating grooves, and the distance between two adjacent L-shaped plates is the same.

[0011] As another improvement of the present application, a plurality of jacking grooves corresponding to the multiple L-shaped plates are jointly dug on the upper end of the fixed plate and the workbench. A jacking assembly is arranged in the jacking grooves. The jacking assembly includes two cylinders fixedly installed at the lower end of the workbench. A fixed rod is fixedly connected to the lower end of the cylinder, and a positioning plate is fixedly connected to the ends of the two fixed rods away from the cylinders.

[0012] As a supplement to another improvement of the present application, a plurality of ejector rods corresponding to the multiple jacking grooves are fixedly connected to the upper end of the positioning plate. The upper end of the ejector rod is fixedly connected to a top plate, and the top plate is located in the jacking grooves on the workbench.

[0013] In summary, during the actual application process, place the steel plate on the fixed plate so that one end of the steel plate is in contact with the baffle. Rotate the screw rod to drive the pressing plate to move downward to limit and fix the steel plate. Then start the electric track to drive the fixed plate to move towards the shearing knife, so that the multiple shearing knives shear the steel plate, thereby evenly shearing the steel plate into multiple plates, and effectively avoiding the situation of the steel plate shifting and shaking during the shearing process, thereby reducing the shearing error of the steel plate and improving the cutting efficiency and accuracy.

Specific embodiments

[0023] The following will make a detailed description of the two embodiments of the present application with reference to the accompanying drawings.

[0024] The first embodiment:

[0025] Figure 1 and Figure 2 Show: A high-efficiency plate shear for steel shovel production, including a workbench 1, multiple cutting grooves 9 are dug at the upper end of the workbench 1, support bars 4 are fixedly connected to both the front and rear ends of the workbench 1, an electric track 5 is fixedly connected to the upper end of the support bar 4. Those skilled in the art can select an appropriate model of the electric track 5 according to actual needs. For example: LRM, a fixing plate 6 is placed at the upper end of the workbench 1, the fixing plate 6 is located on the right side of the cutting knife 3, a slider 7 is slidably connected in the electric track 5, a positioning rod 8 is fixedly connected to the upper end of the slider 7, the electric track 5 can drive the slider 7 to move, so that the fixing plate 6 and the positioning rod 8 move with the movement of the slider 7, thereby pushing the steel plate towards the direction of the cutting knife 3, eliminating the need for manual pushing by workers, improving the cutting efficiency while effectively avoiding the occurrence of safety accidents. The distance between two adjacent cutting grooves 9 is the same as the distance between the outermost cutting groove 9 and the front and rear ends of the workbench 1, making the width of the cut plates the same and improving the cutting accuracy. A protective cover 15 is fixedly connected to the upper ends of the two support bars 4, the protective cover 15 is located directly above the multiple cutting knives 3, and the protective cover 15 can block the debris generated during the cutting process, effectively preventing the debris from splashing everywhere.

[0026] Figure 3It shows that multiple mounting rods are fixedly connected to the lower end of the workbench 1, and a dual-axis motor 2 is fixedly connected to the lower end of the mounting rods. Those skilled in the art can select a suitable model of the dual-axis motor 2 according to actual needs. For example: 42BYG47-1.7A-23D. Both output ends of the dual-axis motor 2 are fixedly connected with shearing knives 3. The dual-axis motor 2 can drive the shearing knives 3 to rotate, thereby shearing the steel plate. One end of the shearing knife 3 close to the workbench 1 penetrates through the cutting groove 9. The numbers of the dual-axis motor 2 and the cutting groove 9 are both even numbers, and the number of the dual-axis motor 2 is half of the number of the cutting groove 9.

[0027] Figure 4 and Figure 5 It shows that one end of the positioning rod 8 away from the slider 7 is fixedly connected to one end of the fixed plate 6 close to the shearing knife 3. A plurality of accommodating grooves corresponding to the plurality of cutting grooves 9 are drilled in the upper end of the fixed plate 6. The accommodating grooves can effectively prevent the shearing knife 3 from shearing the fixed plate 6. A baffle 10 and a plurality of L-shaped plates 11 located on the right side of the baffle 10 are fixedly connected to the upper end of the fixed plate 6. The baffle 10 is located on the right side of the accommodating groove. A pressing plate 12 is arranged at the lower end of the L-shaped plate 11. A screw rod 13 and two limiting rods 14 are arranged at the upper end of the L-shaped plate 11. The lower end of the screw rod 13 threadedly penetrates through the L-shaped plate 11 and is rotatably connected to the upper end of the pressing plate 12. The lower end of the limiting rod 14 movably penetrates through the L-shaped plate 11 and is fixedly connected to the upper end of the pressing plate 12. The limiting rod 14 can limit the pressing plate 12, forcing the pressing plate 12 to move only in the vertical direction. The number of the L-shaped plates 11 is one more than the number of the accommodating grooves. The distance between two adjacent L-shaped plates 11 is the same. The number of the sheared plates is one more than the number of the shearing knives 3, so that the pressing plate 12 can limit and fix each plate.

[0028] During use, place the steel plate on the fixed plate 6 so that one end of the steel plate is in contact with the baffle 10. Rotate the screw rod 13 to drive the pressing plate 12 to move downward to limit and fix the steel plate. Then start the electric track 5 to drive the fixed plate 6 to move towards the shearing knife 3, so that the plurality of shearing knives 3 shear the steel plate, thereby evenly shearing the steel plate into a plurality of plates, and effectively preventing the steel plate from shifting and shaking during the shearing process, thereby reducing the error of steel plate shearing and improving the cutting efficiency and accuracy.

[0029] The second embodiment:

[0030] On the basis of the first embodiment, this embodiment adds a jacking groove and a jacking component, and the rest is the same as the first embodiment.

[0031] Figure 6 and Figure 7It is shown that: A plurality of jacking grooves corresponding to a plurality of L-shaped plates 11 are jointly drilled in the fixing plate 6 and the upper end of the workbench 1. A jacking assembly is arranged in the jacking grooves. The jacking assembly includes two cylinders 16 fixedly installed at the lower end of the workbench 1. Those skilled in the art can select a suitable model of the cylinder 16 according to actual needs. For example: SCD50x100-100-LB. A fixing rod 17 is fixedly connected to the lower end of the cylinder 16. The two fixing rods 17 are fixedly connected together at the ends away from the cylinder 16. A positioning plate 18 is fixedly connected to the upper end of the positioning plate 18. A plurality of ejector rods 19 corresponding to a plurality of jacking grooves are fixedly connected to the upper end of the ejector rod 19. The upper end of the ejector rod 19 is fixedly connected to a top plate 20. The top plate 20 is located in the jacking groove on the workbench 1.

[0032] During use, the electric track 5 drives the sheared plate to reset. Rotating the screw 13 in the reverse direction drives the pressing plate 12 to separate from the plate. Then start the cylinder 16 to contract, driving the positioning plate 18 to move upward, so that the ejector rod 19 pushes the top plate 20 upward, jacking up the sheared plate, creating a gap between the plate and the fixing plate 6, thus facilitating the staff to take out the sheared plate.

[0033] Combined with the current actual requirements, the above-mentioned implementation manner adopted in this application, the scope of protection is not limited thereto. Within the knowledge range of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
