Description

Technical Field

[0001] This application relates to the technical field of plate shears, and particularly to a plate shear. Background Art

[0002] A plate shear is a machine that uses a blade to make a reciprocating linear motion to shear plates. It applies a shearing force to metal plates of various thicknesses with the help of the moving blade, causing the plates to break and separate according to the required dimensions.

[0003] Currently, the prior art discloses a plate shear, including a workbench, a hydraulic cylinder, and a blade. The hydraulic cylinder is installed on the top of the workbench. An installation plate is fixed to the end of the piston rod of the hydraulic cylinder, and the blade is fixed to the bottom of the installation plate. An avoidance groove for the blade to enter is formed on the workbench. When shearing the plate, the plate is placed on the top, and then the plate is slid towards the blade until the plate is directly below the blade. Then, the hydraulic cylinder is started to drive the blade to move downward to shear the plate.

[0004] When shearing the plate, the feeding side of the workbench supports the plate. At this time, if the plate is relatively soft, the plate is likely to bend under the action of gravity when being transmitted towards the blade, increasing the difficulty of feeding the plate. Summary of the Utility Model

[0005] In order to reduce the difficulty of feeding the plate, this application provides a plate shear.

[0006] This application provides a plate shear, adopting the following technical solutions:

[0007] A plate shear, including

[0008] a machine body;

[0009] mounting columns, arranged on the feeding side of the machine body, there are multiple groups of mounting columns arranged at intervals, each group of mounting columns has multiple and is evenly spaced, and sliding balls are arranged on the tops of the mounting columns;

[0010] a support plate, arranged on the feeding side of the machine body, a through hole is formed on the support plate, and the mounting columns pass through the through hole.

[0011] By adopting the above technical solutions, multiple groups of mounting columns are arranged at intervals on the feeding side of the machine body, each group of mounting columns is evenly spaced, and sliding balls are arranged on the tops. This design enables the plate shear to stably support and guide the plate to be sheared through the arrangement of the mounting columns and sliding balls during feeding, reducing the friction generated by the plate during feeding. At the same time, the setting of the support plate increases the stability of supporting the plate, ensuring the smooth progress of the shearing process.

[0012] Optionally, the sliding balls are rotatably connected to the mounting columns.

[0013] By adopting the above technical solution, this improvement enables the sliding ball to rotate freely when the sheet passes through, reducing the friction between the sheet and the sliding ball and the resistance during the shearing process, thereby further improving the feeding speed and shearing efficiency of the sheet. At the same time, the rotation of the sliding ball also reduces the impact of the sheet on the mounting column and extends the service life of the equipment.

[0014] Optionally, a mounting frame is provided on the feeding side of the machine body. The support plate can deform. The support plates are connected end to end and rotatably connected to the mounting frame.

[0015] The mounting column is slidably connected to the mounting frame. The mounting column has a telescopic columnar structure. The number of holes formed in the support plate is a multiple of the number of mounting columns.

[0016] By adopting the above technical solution, the support plates can be connected end to end and rotatably connected to the mounting frame, and the mounting column is slidably connected to the mounting frame. This design enables the position of the mounting column to be adjusted, which is beneficial to adapting to sheets of different widths.

[0017] Optionally, the mounting frame is symmetrically provided with support bars having an elliptical annular structure. The support plate slides on the support bars, and the mounting column is located between the opposite support bars.

[0018] By adopting the above technical solution, the support plate slides on the support bars, and this design further enhances the stability and supporting force of the support plate.

[0019] Optionally, a plurality of connecting rings are evenly spaced on the inner wall of the circumferential side of the support plate. The support bars pass through the connecting rings and are slidably connected.

[0020] By adopting the above technical solution, a plurality of connecting rings are evenly spaced on the inner wall of the circumferential side of the support plate. The support bars pass through the connecting rings and are slidably connected. This connection method not only increases the connection strength between the support plate and the support bars but also makes the support plate more stable during the sliding process.

[0021] Optionally, the mounting frame is provided with a plurality of rotating rollers for the support plate to sleeved. The end of the rotating roller is provided with a rotating shaft rotatably connected to the mounting frame, and the support bar corresponds to the rotating shaft.

[0022] The mounting frame is threadedly connected with a tightening bolt that can abut against the end of the rotating shaft.

[0023] By adopting the above technical solution, the setting of the rotating rollers makes the rotation of the support plate smoother, reducing friction and resistance. The tightening bolt can abut against the rotating shaft, making the support plate enter a fixed state and reducing the possibility of the support plate sliding when the sheet is input.

[0024] Optionally, a connecting rack is provided on the outer peripheral side of the rotating roller, and a connecting tooth groove is formed on the inner peripheral side wall of the support plate. The connecting rack meshes with the connecting tooth groove;

[0025] A toggle shaft is rotatably connected to the mounting bracket. The toggle shaft is coaxially arranged and connected to the rotating shaft.

[0026] By adopting the above technical solution, when the rotating roller rotates, the support plate is driven to move through the interaction between the connecting tooth groove and the connecting rack.

[0027] Optionally, the mounting post includes an inner post, an outer post and a connecting spring. The outer post slides on the mounting bracket, and the inner post slides up and down in the outer post. A linkage bar is connected between adjacent inner posts of the same group of mounting posts;

[0028] The connecting spring is arranged on the outer post, and the connecting spring drives the inner post to protrude out of the outer post.

[0029] By adopting the above technical solution, when the position of the mounting post needs to be adjusted, first press and toggle the inner post to disengage from the through hole, and then the mounting post can be slid to adjust the position of adjacent groups of mounting posts, so that the mounting post can adapt to plates of different widths.

[0030] In summary, the present application includes at least one of the following beneficial effects:

[0031] 1. Multiple groups of mounting posts are arranged at intervals on the feeding side of the machine body. Each group of mounting posts is evenly spaced, and a sliding ball is provided at the top. This design enables the shearing machine to stably support and guide the plate to be sheared through the arrangement of the mounting posts and the sliding balls during feeding, reducing the friction generated by the plate during feeding. At the same time, the setting of the support plate increases the stability of supporting the plate, ensuring the smooth progress of the shearing process;

[0032] 2. The support plates can be connected end to end and rotatably connected to the mounting bracket, and the mounting posts are slidably connected to the mounting bracket. This design enables the position of the mounting posts to be adjusted, which is beneficial for adapting to plates of different widths. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is combined with Figures 1-5 This application is described in further detail.

[0040] The embodiment of the present application discloses a shearing machine.

[0041] Example 1

[0042] See also Figure 1 The shearing machine includes a body 1, mounting columns 2, and a support plate 3. The mounting columns 2 are fixedly connected to the feed side of the body 1. The mounting columns 2 are arranged in multiple groups and spaced apart, with each group containing multiple mounting columns 2 evenly spaced apart. A rotation groove is formed at the top of each mounting column 2. The mounting column 2 is provided with a sliding ball 21, which slides into the rotation groove. The mounting column 2 is provided with a retaining ring. The inner diameter of the retaining ring is smaller than the diameter of the sliding ball 21. The retaining ring is engaged with the notch of the rotation groove, and a portion of the sliding ball 21 passes through the retaining ring and protrudes out of the rotation groove.

[0043] The support plate 3 is fixedly connected to the feed side of the machine body 1, and a plurality of through holes 31 are formed on the support plate 3. The through holes 31 correspond one-to-one to the mounting columns 2. The mounting columns 2 pass through the corresponding through holes 31, and the top end faces of the mounting columns 2 and the top end faces of the support plate 3 are in the same plane.

[0044] The implementation principle of a shearing machine in the first embodiment of the present application is as follows:

[0045] When the plate is sheared, the plate slides on the sliding ball 21, and at the same time, the edge parts of the plate on both sides away from the sliding ball 21 slide on the support plate 3. While reducing the friction between the plate and the support plate 3, the plate is supported by the support plate 3, reducing the difficulty of feeding the plate into the machine body 1.

[0046] Example 2

[0047] The difference between the second embodiment of the present application and the first embodiment is that:

[0048] See also Figure 2 and Figure 3 The feed side of the machine body 1 is fixedly connected with a mounting frame 4, which is used to support the support plate 3 and the mounting column 2 (the mounting column 2 isFigure 4 (marked out).

[0049] See Figure 3 and Figure 4 In addition, a plurality of rotating rollers 5 are further provided on the mounting frame 4. In the embodiment of the present application, the number of the rotating rollers 5 is four. The rotating rollers 5 are arranged at intervals horizontally and vertically, and the connecting lines between the central axes of the rotating rollers 5 form a rectangular structure. A rotating shaft 51 is provided at each end of each rotating roller 5, and the rotating shaft 51 is rotatably connected to the mounting frame 4 through a bearing.

[0050] The support plate 3 is made of a flexible material such as an elastic metal sheet or a polymer material and has a certain deformation ability. The head and tail ends of the support plate 3 are fixedly connected by welding, so that the support plate 3 forms an annular structure. The support plate 3 is sleeved on the outer peripheral side of the rotating roller 5, so that the support plate 3 is rotatably connected to the mounting frame 4, and the support plate 3 can rotate within a certain range. At the same time, the mounting column 2 is slidably connected to the mounting frame 4 through a slider and a slide rail structure, allowing the mounting column 2 to slide on the mounting frame 4 along the extending direction of the support plate 3. By sliding the support plate 3, the position of the mounting column 2 can be directly moved, so that the position of the plate fed into the machine body 1 changes, making full use of different positions of the blades in the machine body 1 to cut the plate and maintaining the sharpness of the blades in the machine body 1 when cutting the plate.

[0051] The mounting column 2 includes an inner column 22, an outer column 23 and a connecting spring 24. The outer column 23 slides on the mounting frame 4, and the outer column 23 is formed with a connecting groove. The inner column 22 slides up and down in the connecting groove, and a linkage bar is fixedly connected between adjacent inner columns 22 of the same group of mounting columns 2. The connecting spring 24 is installed in the connecting groove. The top of the connecting spring 24 abuts against the bottom of the inner column 22, and the bottom of the connecting spring 24 abuts against the bottom wall of the connecting groove. When the connecting spring 24 elastically releases, it drives the inner column 22 to protrude out of the outer column 23, and at the same time enables the inner column 22 to pass through the through hole 31, so that the top end surface of the inner column 22 is in the same plane as the top end surface of the support plate 3. When the position of the mounting column 2 needs to be adjusted, first press and move the inner column 22 downward to disengage from the through hole 31, and then the mounting column 2 can be slid to adjust the positions of adjacent groups of mounting columns 2, so that the mounting column 2 can adapt to plates of different widths.

[0052] In addition, a pair of elliptical annular support bars 11 are symmetrically fixed on the mounting frame 4, and the rotating shafts 51 pass through the support bars 11 in a one-to-one correspondence. The inner peripheral side wall of the support plate 3 slides on the outer peripheral side wall of the support bars 11, and the support plate 3 is supported by the support bars 11 to improve the support ability of the support plate 3 for the plate.

[0053] At the same time, multiple connecting rings 32 are evenly spaced and fixed to the inner sidewall of the support plate 3. The support bar 11 passes through the connecting rings 32, and these connecting rings 32 can slide on the support bar 11. This design ensures that the support plate 3 can deform and rotate stably while limiting its deformation range, reducing the risk of excessive deformation of the support plate 3 affecting its support effect on the plate.

[0054] See also Figure 4 and Figure 5 In order to facilitate the sliding of the support plate 3, the mounting frame 4 is rotatably connected to a toggle shaft 42, which is coaxially arranged and fixedly connected to one of the rotating shafts 51. When the toggle shaft 42 is rotated, the rotating shaft 51 rotates along with the toggle shaft 42, causing the support plate 3 to enter a sliding state.

[0055] The inner sidewall of the support plate 3 is further formed with a plurality of connecting teeth and grooves 33. An annular connecting rack 52 is fixedly connected to the outer side of the rotating roller 5. The connecting rack 52 meshes with the connecting teeth and grooves 33. When the rotating roller 5 rotates, the connecting teeth and grooves 33 interact with the connecting rack 52, thereby driving the support plate 3 to move.

[0056] A retaining bolt 41 is rotatably connected to the mounting bracket 4. In the present embodiment, there is only one retaining bolt 41; in other embodiments, there may be multiple retaining bolts 41. Retaining bolt 41 engages the rotating shaft 51. When the retaining bolt 41 is rotated until it abuts against the end of the rotating shaft 51, the rotating roller 5 enters a fixed position. This design stabilizes the support plate 3 and reduces the possibility of the support plate 3 slipping when the plate is fed into the machine body 1.

[0057] The implementation principle of a shearing machine in the second embodiment of the present application is as follows:

[0058] By providing a deformable support plate 3, a slidable mounting post 2, and corresponding connection structures such as a sliding connection structure, a rotating connection structure, and a rack-tooth-groove meshing structure, the shearing machine can flexibly adjust the position of the mounting post 2 according to the shape and size of different plates, providing stable and effective support. At the same time, by optimizing the connection method and position relationship between various components, the stability and performance of the overall structure are further improved.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
