Description

Technical Field

[0001] This invention belongs to the field of shearing, specifically relating to a cutting device for the metal casing of an injection pump. Background Technology

[0002] Currently, metal casing cutting operations using injection pumps mostly rely on manual pushing and positioning. This is not only labor-intensive and inconsistent in positioning accuracy, but also prone to skewed cuts and dimensional errors due to human error. The inability of the workpiece to automatically enter the shearing zone results in low shearing efficiency, and manual proximity to the shearing station poses safety hazards, making it unsuitable for continuous batch production. By setting up automatic workpiece movement to ensure precise entry into the shearing zone, positioning consistency and shearing stability can be effectively improved, safety risks reduced, and the demands for efficient and standardized processing met.

[0003] Patent CN213052968U discloses a cutting device for PC casing production, including a base plate. A cutting device is fixedly installed on the front upper part of the base plate, and two support legs are fixedly installed on the rear upper part of the base plate. A cutting table is fixedly installed on the upper part of the two support legs. Vertical plates are fixedly installed on the left and right upper parts of the cutting table, and a top plate is fixedly installed on the upper part of the vertical plates. Fixing components are fixedly installed on the left and right upper parts of the top plate, and a dust removal device is fixedly installed on the front upper part of the top plate. The cutting device for PC casing production described in this patent uses an exhaust fan to create a vacuum inside the cutting table and uses a clamping device to press the casing tightly, further improving the fixing effect, improving the cutting accuracy, and ensuring the quality of casing production. The exhaust fan collects the waste or dust generated during the cutting process in a water tank, preventing the waste or dust from being emitted into the workshop or the external environment and protecting the health of the workers.

[0004] However, during the shearing process, when the outer shell is pressed and fixed, it is difficult to guide and move the outer shell to the cutting area simultaneously. The outer shell still needs to be initially positioned manually, which can easily lead to cutting safety hazards, affect the subsequent cutting efficiency and safety of the device, and affect the cutting accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting device for the metal casing of an injection pump, so as to solve the problem of easy deviation and vibration during the cutting process of the metal casing of the injection pump.

[0006] To achieve the above objectives, the present invention provides a cutting device for the metal casing of an injection pump, comprising: a fixed platform, an electric push rod mounted on the fixed platform, a connecting frame provided on the fixed platform, a connecting plate rotatably connected to the inner wall of the connecting frame, a motor provided on the connecting plate, a protective cover provided on the connecting plate, a cutting shearing disc provided on the connecting plate, a fixing block one fixedly connected to the telescopic end of the electric push rod, a fixing block two fixedly connected to the inner wall of the connecting plate, an electric slide rail provided on the inner wall of the fixed platform, a moving block fixedly connected to the moving end of the electric slide rail, a support plate mounted on the moving block, and an elastic telescopic rod one rotatably connected to the inner wall of the support plate.

A fixed shearing blade is fixedly connected to the top of the placement plate. This design enables automated cutting, reduces the need for manual pulling of the shearing disc, improves the cutting efficiency of the device, and enhances the cutting safety of the device.

[0007] In one possible implementation, the output end of the motor is equipped with a pulley assembly, a pull column is mounted on the connecting plate, the inner wall of the fixed platform is equipped with a protective mechanism for cutting protection, the inner wall of the protective cover is equipped with a cleaning mechanism for cleaning the surface of the shearing disc, and the first fixed block is rotatably connected to the inner wall of the second fixed block to avoid the impact of vibration during the cutting process on the cutting accuracy. At the same time, the metal shell of the injection pump is driven to the cutting area by the placement plate, and the first fixed block is used to drive the second fixed block to move. The first roller is in contact with the fixed platform and is used to drive the reciprocating screw to rotate. The shearing disc is connected to the pulley assembly, which can avoid the safety hazards caused by the operator preparing in the cutting area and improve the cutting accuracy of the device.

[0008] In one possible implementation, the movable frame is slidably connected to the circumferential surface of the guide post, and the guide post is used to provide movement guidance for the movable frame. The placement plate is in contact with the support plate. The moving end of the electric slide rail will drive the movable block to move. The movement of the movable block will drive the support plate to move. The movement of the support plate will drive the elastic telescopic rod to move. The movement of the elastic telescopic rod will drive the placement plate to move.

[0009] In one possible implementation, the protective mechanism includes a support column fixedly connected to the bottom of the placement plate. A toothed ring is fixedly connected to the bottom of the support column. A rack is slidably connected to the inner wall of the support plate, and a handrail is fixedly connected to the inner wall of the rack. The placement plate synchronously drives the metal housing of the injection pump placed on top of it to rotate at an angle, which can adjust the cutting angle of the metal housing of the injection pump in a timely manner, thereby improving the cutting accuracy of the device on the metal housing of the injection pump and increasing the cutting efficiency of the device.

[0010] In one possible implementation, the protective mechanism further includes a first protective plate, which is fixedly connected to the top of the movable frame. A rotating column is rotatably connected to the inner wall of the first protective plate, and a second protective plate is fixedly connected to the circumferential surface of the rotating column. A guide rod is fixedly connected to the inner wall of the fixed platform, and a rising column is movably connected to the inner wall of the rotating column. A second roller is rotatably connected to the inner wall of the rising column. The cooperation between the first protective plate and the rotating column can isolate the cutting area from the outside world to a certain extent, thereby improving the cutting safety of the device and indirectly improving the cutting efficiency of the device.

[0011] In one possible implementation, the toothed ring is located on the movement trajectory of the rack, and the rack is used to push the toothed ring to rotate. The guide rod is located on the movement trajectory of the second roller, and the guide rod is used to push the second roller to rise in the opposite direction. The inner wall of the rotating column is provided with a non-self-locking spiral groove, and a locking block is provided in the spiral groove of the rotating column. The movement of the moving frame will drive the first protective plate to move, the movement of the first protective plate will drive the rotating column to move, and the movement of the rotating column will synchronously drive the second protective plate to move. During the movement of the rotating column, the rotating column will drive the rising column to move synchronously.

[0012] In one possible implementation, the cleaning mechanism includes an L-block, which is fixedly connected to the top of a support plate. An elastic telescopic rod is fixedly connected to the top of the L-block, and a pressure plate is fixedly connected to the telescopic end of the elastic telescopic rod. A fixing column is fixedly connected to the bottom of the pressure plate, and a groove block is fixedly connected to the top of the rack. The cooperation between the protective plate and the rotating column can isolate the cutting area from the outside world to a certain extent, thereby improving the cutting safety of the device and indirectly improving the cutting efficiency of the device.

[0013] In one possible implementation, the cleaning mechanism further includes an L-block II, which is fixedly connected to the front of the protective cover. A brush plate is fixedly installed on the inner wall of the L-block II, which can perform preliminary cleaning of impurities on the surface of the shearing disc, ensuring the cutting accuracy of the shearing disc and avoiding the impact of debris on the cutting accuracy.

[0014] In one possible implementation, the fixing post contacts the slot block and is used to restrict the movement of the slot block. The fixing post contacts block L, and the shearing disk contacts the brush plate. During the rotation of the shearing disk, the side of the shearing disk will contact the brush plate. At this time, the rotation of the shearing disk will cause the brush on the brush plate to contact the side of the shearing disk.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This metal casing cutting device for the injection pump achieves automated cutting through the coordinated movement of a fixed platform, electric push rod, connecting frame, connecting plate, motor, protective cover, shearing disc, fixed block one, fixed block two, electric slide rail, moving block, support plate, elastic telescopic rod one, placement plate, reciprocating screw, roller one, guide column, moving frame, elastic telescopic rod two, clamping plate, long slot plate, and fixed shearing blade. This reduces the need for manual shearing disc operation, improves cutting efficiency, and enhances cutting safety by preventing vibrations during cutting from affecting accuracy. Furthermore, the long slot plate guides the injection pump's metal casing to the cutting area, preventing safety hazards caused by operators preparing within the cutting area and further improving cutting precision.

[0016] 2. The metal casing cutting device for the injection pump utilizes the coordinated movement of a support column, toothed ring, rack, handrail, protective plate one, rotating column, protective plate two, guide rod, rising column, and roller two. This allows the placement plate to synchronously rotate the metal casing of the injection pump placed on top of it, enabling timely adjustment of the cutting angle. This improves the cutting accuracy and efficiency of the device. The cooperation between protective plate one and the rotating column isolates the cutting area from the outside environment, enhancing the cutting safety and indirectly increasing the cutting efficiency.

[0017] 3. The cutting device for the metal casing of the injection pump, through the coordinated movement of L-block one, elastic telescopic rod three, pressure plate, fixed column, groove block, L-block two, and brush circular plate, causes the groove block to move and limit, which in turn causes the rack to reciprocate and push. This indirectly ensures the stability of the angle adjustment of the metal casing of the injection pump, avoids deviation of the cutting angle, improves the cutting accuracy of the device, and enables the brush circular plate to perform preliminary cleaning of impurities on the surface of the shearing disc, ensuring the cutting accuracy of the shearing disc and preventing the presence of debris on the surface of the shearing disc from affecting the cutting accuracy.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-9As shown, one embodiment of the present invention is: a cutting device for the metal casing of an injection pump, comprising: a fixed platform 1, an electric push rod 2 mounted on the fixed platform 1, a connecting frame 3 provided on the fixed platform 1, a connecting plate 4 rotatably connected to the inner wall of the connecting frame 3, a motor 5 provided on the connecting plate 4, a protective cover 6 provided on the connecting plate 4, a shearing disc 7 provided on the connecting plate 4, a fixing block 10 fixedly connected to the telescopic end of the electric push rod 2, a fixing block 2 11 fixedly connected to the inner wall of the connecting plate 4, an electric slide rail 12 provided on the inner wall of the fixed platform 1, a moving block 13 fixedly connected to the moving end of the electric slide rail 12, and a support plate 14 mounted on the moving block 13. The inner wall of the support plate 14 is rotatably connected to an elastic telescopic rod 15. The telescopic end of the elastic telescopic rod 15 is fixedly connected to a placement plate 16. The inner wall of the support plate 14 is rotatably connected to a reciprocating screw 17. The circumferential surface of the reciprocating screw 17 is fixedly connected to a roller 18. The inner wall of the support plate 14 is fixedly connected to a guide post 19. The circumferential surface of the reciprocating screw 17 is movably connected to a moving frame 20. The right side of the moving frame 20 is fixedly connected to an elastic telescopic rod 21. The telescopic end of the elastic telescopic rod 21 is fixedly connected to a clamping plate 22. The top of the placement plate 16 is fixedly connected to a long groove plate 23. The top of the placement plate 16 is fixedly connected to a fixed shearing blade 24. Before the device is ready for use, the operator must first place the metal casing of the injection pump to be used for cutting in the cutting area on the long slot plate 23. After the preparation is completed, the electric push rod 2 will start, and the telescopic end of the electric push rod 2 will drive the fixed block 10 to rise. During the rising process, the fixed block 10 will simultaneously drive the fixed block 2 11 to rise. However, at this time, the fixed block 10 is fixedly connected to the connecting plate 4, and the connecting plate 4 rotates on the connecting frame 3. At this time, during the rising process, the fixed block 2 11 will simultaneously rotate, and the fixed block 2 11 will drive the connecting plate 4 to rotate. When the connecting plate 4 rotates, it will drive the protective cover 6 to rotate. At the same time, the connecting plate 4 will also drive the shearing disc 7 to rotate and descend. During the rotation, the connecting plate 4 will drive the motor 5 to rotate. The motor 5 will drive the pulley assembly at its output end to move synchronously. At the same time, the motor 5 will start and drive the shearing disc 7 to rotate through the pulley assembly. After the shearing disc 7 moves, it will cooperate with the fixed shearing blade 24 to cut the workpiece. This can realize automated shearing, reduce the manual pulling of the shearing disc 7 for shearing, improve the shearing efficiency of the device, and improve the shearing safety of the device. The output end of the motor 5 is equipped with a pulley assembly, the connecting plate 4 is equipped with a pull column, the inner wall of the fixed platform 1 is equipped with a protective mechanism 8 for cutting protection, the inner wall of the protective cover 6 is equipped with a cleaning mechanism 9 for cleaning the surface of the shearing disc 7, the first fixed block 10 is rotatably connected to the inner wall of the second fixed block 11, and the first fixed block 10 is used to drive the second fixed block 11 to move, the first roller 18 is in contact with the fixed platform 1, and the first roller 18 is used to drive the reciprocating screw 17 to rotate, the shearing disc 7 is connected to the pulley assembly, the moving frame 20 is slidably connected to the circumferential surface of the guide column 19, and the guide column 19 is used to provide moving guidance for the moving frame 20, and the placement plate 16 is in contact with the support plate 14. When the device is in use, after the operator places the metal casing of the injection pump to be cut into the cutting area of ​​the placement plate 16, the electric slide rail 12 will start simultaneously. The moving end of the electric slide rail 12 will drive the moving block 13 to move. The movement of the moving block 13 will drive the support plate 14 to move. The movement of the support plate 14 will drive the elastic telescopic rod 15 to move. The movement of the elastic telescopic rod 15 will drive the placement plate 16 to move. During the movement of the placement plate 16, the placement plate 16 will drive the long slot plate 23 to move. At the same time, the placement plate 16 will also drive the fixed shearing blade 24. At this time, the long slot plate 23 can drive the metal casing of the injection pump on itself to move, so that the metal casing of the injection pump gradually approaches and reaches the cutting area. At the same time, during the movement of the support plate 14, the support plate 14 will drive the reciprocating screw 17 to move. The movement of the reciprocating screw 17 will drive the roller 18 to move. During the movement of the roller 18, the roller 18 will generate motion friction due to contact with the fixed table 1. At this time, the roller 18 moves... During the process, roller 18 rotates around itself and drives reciprocating screw 17 to rotate. The rotation of reciprocating screw 17 drives moving frame 20 to rotate. However, moving frame 20 is limited by the movement of guide post 19. Guide post 19 causes moving frame 20 to move laterally only through the reciprocating groove on the surface of reciprocating screw 17 during the rotation of reciprocating screw 17. The movement of moving frame 20 drives elastic telescopic rod 21 to move. During the movement of elastic telescopic rod 21, elastic telescopic rod 21 drives clamping plate 22 to move. After moving a certain distance, clamping plate 22 will contact the metal shell of injection pump and fix the metal shell of injection pump through the telescopic characteristics of elastic telescopic rod 21. This can avoid the impact of vibration during the cutting process on cutting accuracy. At the same time, the long groove plate 23 drives the metal shell of injection pump to the cutting area, which can avoid the safety hazards caused by the operator preparing in the cutting area and improve the cutting accuracy of the device. Overall working principle: After the shearing disc 7 moves, it cooperates with the fixed shearing blade 24 to shear the workpiece, realizing automated shearing and reducing the manual pulling of the shearing disc 7 for shearing, thus improving the shearing efficiency of the device. It also improves the shearing safety of the device. The clamping plate 22 contacts the metal housing of the injection pump and fixes the metal housing of the injection pump through the telescopic characteristics of the elastic telescopic rod 21, which can avoid the impact of vibration during the cutting process on the cutting accuracy. At the same time, the long slot plate 23 drives the metal housing of the injection pump to the cutting area, which can avoid the safety hazards caused by the operator preparing in the cutting area, thus improving the cutting accuracy of the device.

[0022] like Figures 1-9 As shown, in another embodiment of the present invention based on the above embodiments, the protective mechanism 8 includes a support column 801, the support column 801 is fixedly connected to the bottom of the placement plate 16, the bottom of the support column 801 is fixedly connected to a toothed ring 802, the inner wall of the support plate 14 is slidably connected to a rack 803, and the inner wall of the rack 803 is fixedly connected to a handrail 804. After the injection pump's metal casing is placed on top of the placement plate 16, its own weight will transfer the compressive force to the elastic telescopic rod 15 through the placement plate 16, causing the placement plate 16 to move downwards. This movement of the placement plate 16 will cause the support column 801 to move, which in turn will cause the toothed ring 802 to move synchronously. After moving a certain distance, the toothed ring 802 will be positioned on the trajectory of the rack 803. If the cutting angle needs to be changed at this point, the operator can push the handle 804 to move it. The movement of the handle 804 will then... The rack 803 moves, and during this movement, it drives the gear ring 802 to rotate. The rotation of the gear ring 802 drives the support column 801 to rotate synchronously. The support column 801 drives the placement plate 16 to rotate. During this rotation, the placement plate 16 drives the long slot plate 23 to rotate. The long slot plate 23 synchronously drives the metal housing of the injection pump placed on top of it to rotate at an angle. This allows for timely adjustment of the cutting angle of the metal housing of the injection pump, improving the cutting accuracy and efficiency of the device. The protective mechanism 8 also includes a protective plate 805, which is fixedly connected to the top of the movable frame 20. A rotating column 806 is rotatably connected to the inner wall of the protective plate 805. A protective plate 807 is fixedly connected to the circumferential surface of the rotating column 806. A guide rod 808 is fixedly connected to the inner wall of the fixed platform 1. A rising column 809 is movably connected to the inner wall of the rotating column 806. A roller 810 is rotatably connected to the inner wall of the rising column 809. A gear ring 802 is located on the movement trajectory of the rack 803, and the rack 803 is used to push the gear ring 802 to rotate. The guide rod 808 is located on the movement trajectory of the roller 810, and the guide rod 808 is used to push the roller 810 to rise in the opposite direction. A non-self-locking spiral groove is opened on the inner wall of the rotating column 806, and a locking block is set in the spiral groove of the rotating column 806. When the device is preparing to cut, the movement of the moving frame 20 will cause the protective plate 805 to move. The movement of the protective plate 805 will cause the rotating column 806 to move. The movement of the rotating column 806 will simultaneously cause the protective plate 807 to move. During the movement of the rotating column 806, the rotating column 806 will cause the rising column 809 to move synchronously. The movement of the rising column 809 will cause the roller 810 to move. After the roller 810 has moved a certain distance, it will contact the guide rod 808. At this time, the guide rod 808 can guide the roller 810, causing the roller 810 to rise during the movement. The rise of the roller 810 will drive the rotating column 806 to rotate through the locking block and the spiral groove opened in the rotating column 806. The rotation of the rotating column 806 will drive the protective plate 807 to rotate. At this time, the cooperation of the protective plate 805 and the rotating column 806 can isolate the cutting area from the outside world to a certain extent, improve the cutting safety of the device, and indirectly improve the cutting efficiency of the device. The cleaning mechanism 9 includes an L-block 901, which is fixedly connected to the top of the support plate 14. An elastic telescopic rod 902 is fixedly connected to the top of the L-block 901. A pressure plate 903 is fixedly connected to the telescopic end of the elastic telescopic rod 902. A fixing column 904 is fixedly connected to the bottom of the pressure plate 903. A groove block 905 is fixedly connected to the top of the rack 803. When the operator needs to push the rack 803, the operator simultaneously pulls the pressure plate 903. The rise of the pressure plate 903 will drive the fixed column 904 to rise. At the same time, during the movement of the rack 803, the rack 803 will drive the slot block 905 to move. When the rack 803 has been pushed to the appropriate distance, the pressure plate 903 is released. The pressure plate 903 will be reset through the elastic telescopic rod 902. The pressure plate 903 will drive the fixed column 904 to reset. At this time, the fixed column 904 will contact the slot block 905 and limit the movement of the slot block 905. The movement limit of the slot block 905 will cause the rack 803 to push back and forth, which can indirectly ensure the stability of the angle adjustment of the metal shell of the injection pump, avoid the deviation of the cutting angle, and improve the cutting accuracy of the device. The cleaning mechanism 9 also includes L-block 2 906, which is fixedly connected to the front of the protective cover 6. A brush plate 907 is fixedly installed on the inner wall of L-block 2 906. A fixing post 904 contacts the groove block 905 and is used to limit the movement of the groove block 905. The fixing post 904 contacts L-block 1 901, and the shearing disc 7 contacts the brush plate 907. When the device is in use, during the rotation of the shearing disc 7, the side of the shearing disc 7 will come into contact with the brush plate 907. At this time, the rotation of the shearing disc 7 will cause the brush on the brush plate 907 to come into contact with the side of the shearing disc 7, which can achieve the initial cleaning of impurities on the surface of the shearing disc 7 by the brush plate 907, thus ensuring the cutting accuracy of the shearing disc 7 and avoiding the impact of impurities on the cutting accuracy due to the presence of impurities on the surface of the shearing disc 7.

[0023] Overall working principle: The placement plate 16 synchronously drives the metal casing of the injection pump placed on top of it to rotate at an angle, which can adjust the cutting angle of the injection pump metal casing in a timely manner, thereby improving the cutting accuracy and efficiency of the device. The cooperation between the protective plate 805 and the rotating column 806 can isolate the cutting area from the outside world to a certain extent, improving the cutting safety of the device and indirectly improving its cutting efficiency. The movement limit of the slot block 905 causes the rack 803 to reciprocate, which can indirectly ensure the stability of the angle adjustment of the injection pump metal casing, avoid deviation of the cutting angle, and improve the cutting accuracy of the device. It can also enable the brush plate 907 to perform preliminary cleaning of impurities on the surface of the shearing disk 7, ensuring the cutting accuracy of the shearing disk 7 and preventing the presence of impurities on the surface of the shearing disk 7 from affecting the cutting accuracy.
