Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of flattening and shearing line, especially to a shearing device with positioning for flattening and shearing line. BACKGROUND

[0002] The shearing device for flattening and shearing line is a device for accurately shearing the flattened plate in the metal processing production line. It is an important part of the flattening and shearing line, and its main function is to accurately and efficiently shear the flattened plate. The working principle of the shearing device for flattening and shearing line is relatively simple but efficient. During the shearing process, the plate is first flattened by the flattening machine to ensure its flatness and accuracy. Then, the plate is transported to the shearing area, and the positioning system accurately positions the plate. Next, the driving system starts, driving the blade to reciprocate and shear the plate.

[0003] The existing shearing device can only position the two sides of the plate. When the plate is sheared, the plate near the shearing area is prone to shaking, which may affect the accuracy of the cut material.

[0004] The existing patent (publication number: CN222268798U) discloses a plate shearing positioning device, which includes a base, a first motor fixedly connected to the middle of the back of the base, a double screw rod fixedly connected to the output end of the first motor, and a first sliding block threadedly connected to the outer surface of the double screw rod on both sides. This plate shearing positioning device ensures the movement of the plate while limiting and guiding the two sides of the plate through two sets of guide wheels. Under the elastic action of the spring, the plug rod drives the bottom support plate to move downward, making the compression wheel contact the surface of the plate, thereby avoiding the phenomenon of upward and downward shaking and deviation during shearing.

[0005] To solve the above problems, the existing patent provides a solution that, under the elastic action of the spring, the plug rod drives the bottom support plate to move downward, making the compression wheel tightly contact the surface of the plate, thereby avoiding the phenomenon of upward and downward shaking and deviation during shearing. However, it is inconvenient to lubricate the shearing knife. After long-term use, the shearing knife cannot be effectively lubricated, which affects the smooth operation of the shearing knife during shearing, causing the shearing knife to wear out and reducing the service life of the device. SUMMARY

DETAILED DESCRIPTION

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0027] The present application provides a technical scheme:

[0028] Please refer to Figures 1 to 4The utility model provides a kind of shearing device with positioning flattening shearing line, including device pedestal 1, the upper surface of device pedestal 1 is fixed with mounting bracket 2, the upper surface of mounting bracket 2 is fixed with two hydraulic cylinders 3 by bolt, the telescopic end of two hydraulic cylinders 3 is fixed with connecting piece 4, the two sides of connecting piece 4 are equipped with the pressure mechanism for workpiece pressure, the lower of pressure mechanism is equipped with the lubricating mechanism for blade lubrication, the two ends of connecting piece 4 are equipped with the guide mechanism for blade guide;

[0029] Pressure mechanism includes connecting rod 5, connecting rod 5 is equipped with two groups, two groups of connecting rod 5 are fixed in the two sides of connecting piece 4, the lower end of two groups of connecting rod 5 is fixed with mounting tube 51, the lower end of mounting tube 51 is telescopically connected with movable rod 53;

[0030] Lubricating mechanism includes pressure plate 6, pressure plate 6 is fixed in the lower end of movable rod 53, mounting tube 51 is internally installed with the pressure spring 52 of movable rod 53 abutment connection, the inside of pressure plate 6 is installed with two liquid storage cotton 61, one side of two liquid storage cotton 61 is fixed with hollow plate 62, the side wall of two liquid storage cotton 61 is all abutment connection with limit spring 63, the upper surface of hollow plate 62 is opened with the through hole 64 of liquid storage cotton 61 intercommunication, the upper end of pressure plate 6 is fixed with the liquid storage tank 65 of through hole 64 intercommunication, connecting piece 4 is inserted with shearing knife 7 in the inside, the side wall of connecting piece 4 is installed with fixed bolt 8 of shearing knife 7 abutment connection.

[0031] By adopting the above technical solution, before using the shearing device for the leveling and shearing line with positioning, the device base 1 is first installed in a suitable position. During use, the workpiece to be processed is placed on the device base 1. The hydraulic cylinder 3 on the mounting frame 2 drives the connecting piece 4 to move, causing the shearing blade 7 to move downwards and shear the workpiece. Simultaneously, the movement of the connecting piece 4 drives the connecting rod 5 to move synchronously, causing the pressure plate 6 on the movable rod 53 to first contact the upper surface of the workpiece, clamping and positioning it, effectively reducing workpiece displacement. As the connecting piece 4 continues to move, the movable rod 53 extends and retracts into the mounting tube 51, compressing the pressure spring 52. After the pressure plate 6 contacts the upper surface of the workpiece, the connecting piece 4... The moving shearing blade 7 passes through the interior of the clamping plate 6. Simultaneously, the vertical movement of the shearing blade 7 pushes the liquid storage cotton 61 on both sides to move horizontally. At this time, the liquid storage cotton 61 drives the limit spring 63 to compress and drives the hollow plate 62 to move, so that the through hole 64 on the hollow plate 62 connects with the liquid storage tank 65. At this time, the lubricating oil stored in the liquid storage tank 65 can enter the hollow plate 62 through the through hole 64 and then enter the liquid storage cotton 61. When the shearing blade 7 finishes shearing the workpiece, the hydraulic cylinder 3 drives the shearing blade 7 to reset. When the shearing blade 7 rises, because there is lubricating oil on the surface of the liquid storage cotton 61, under the action of the elasticity of the limit spring 63, it will press the liquid storage cotton 61 and the side wall of the shearing blade 7 tightly together, thereby lubricating the surface of the shearing blade 7 and achieving the effect of automatic lubrication.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the guide mechanism includes two limit blocks 9. Both limit blocks 9 are fixed to both ends of the connector 4. One side of each limit block 9 is connected to an installation part 91. The installation part 91 has a limit groove 92 that slides and connects with the limit block 9 inside.

[0033] By adopting the above technical solution, the limiting block 9, under the action of the mounting part 91 and the limiting groove 92, plays a guiding role. By unscrewing the fixing bolt 8 on the connecting part 4, the shearing blade 7 can be disassembled and replaced.

[0034] Working principle: The workpiece to be processed is placed on the device base 1. The hydraulic cylinder 3 drives the connecting piece 4 to move, and the shearing blade 7 moves downward to shear the workpiece. At the same time, the movement of the connecting piece 4 drives the connecting rod 5 to move synchronously, so that the clamping plate 6 on the movable rod 53 first contacts the upper surface of the workpiece to clamp and position it. As the connecting piece 4 continues to move, the movable rod 53 extends and retracts into the mounting tube 51 to compress the clamping spring 52. After the clamping plate 6 contacts the upper surface of the workpiece, the connecting piece 4 drives the shearing blade 7 to move downward. The cutter 7 passes through the interior of the pressure plate 6. The vertical movement of the shearing blade 7 will push the liquid storage cotton 61 on both sides to move horizontally. At this time, the liquid storage cotton 61 drives the limiting spring 63 to compress and drive the hollow plate 62 to move, so that the through hole 64 on the hollow plate 62 and the liquid storage tank 65 are connected, and the lubricating oil enters the liquid storage cotton 61. When the shearing blade 7 rises, because there is lubricating oil on the surface of the liquid storage cotton 61, under the action of the elasticity of the limiting spring 63, the liquid storage cotton 61 and the side wall of the shearing blade 7 will be pressed tightly together, thereby lubricating the surface of the shearing blade 7.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
