Description

Technical Field

[0001] The utility model relates to the technical field of punching machine tools, in particular to a punching machine tool protection device. Background Art

[0002] Stamping is a forming process that uses a press and a die to apply external force to plates, strips, pipes, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging belong to the same category of plastic processing (or pressure processing), collectively known as forging. The blanks used for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60-70% of the world's steel is sheet material, most of which is stamped into finished products. Automobile bodies, chassis, fuel tanks, radiators, boiler drums, container shells, and silicon steel sheets for the iron cores of motors and electrical appliances are all stamped. A large number of stamped parts are also found in products such as instruments and meters, household appliances, bicycles, office machinery, and daily utensils.

[0003] However, in the traditional stamping process, the operator generally needs to stand in front of the stamping equipment to operate the control buttons to control the stamping. Due to the high stamping force during the stamping process, metal debris may sometimes fly, which may cause the operator to be injured by the debris. Utility Model Content

[0004] In order to solve the above technical problems, a stamping machine tool protection device is provided. This technical solution solves the problem proposed in the above background technology that in the traditional stamping process, the operator generally needs to stand in front of the stamping equipment to operate the control button to control the stamping. Due to the high stamping force during the stamping process, metal debris may sometimes be splashed, which may cause the operator to be injured by the debris.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A punching machine tool protection device comprises a workbench, a connecting plate fixedly mounted on the top left side of the workbench, a top plate fixedly mounted on the top of the connecting plate, a punching device fixedly mounted on the bottom end of the top plate, a protective mechanism provided on the top of the top plate, a control platform provided on the right side of the workbench, and a control button provided on the top of the control platform;

[0007] The protection mechanism includes a motor, which is arranged at the top of the top plate, and the output end of the motor passes through the top plate and is fixedly installed with a screw rod, and the bottom end of the top plate is provided with a first guide rod, and the outer surface of the screw rod is respectively threadedly connected with a first slider and a second slider, and the first slider and the second slider are both slidably connected to the outer surface of the first guide rod.

[0008] Preferably, the two sets of threads provided on the surface of the screw rod have opposite rotation directions.

[0009] Preferably, the first connecting rod is fixedly installed on the front and rear sides of the first slider through a connecting piece, a front protection plate is fixedly installed on the right side of the first connecting rod, a mounting plate is fixedly installed on the top of the first connecting rod, a fixing plate is fixedly installed on the top of the mounting plate, two groups of second guide rods are fixedly installed on the inner side of the fixing plate, and the outer surfaces of the two groups of second guide rods are slidably installed with a third slider.

[0010] Preferably, two sets of movable connecting rods are rotatably installed on the left side of the second slider, and the other ends of the two sets of movable connecting rods are rotatably installed with fixed blocks, and the two sets of fixed blocks are fixedly installed on the top ends of the two sets of third sliders through second connecting rods.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0024] Reference Figure 1-4 As shown, a punching machine tool protection device includes a workbench 1, characterized in that a connecting plate 2 is fixedly installed on the top left side of the workbench 1, a top plate 3 is fixedly installed on the top of the connecting plate 2, a punching device 4 is fixedly installed on the bottom end of the top plate 3, a protection mechanism 5 is provided on the top of the top plate 3, a control platform 6 is provided on the right side of the workbench 1, a control button 7 is provided on the top of the control platform 6, the protection mechanism 5 includes a motor 501, the motor 501 is fixedly installed at the bottom end of the motor base, and the motor base is fixedly installed on the top end 3, the motor 501 is arranged at the top end of the top plate 3, the output end of the motor 501 passes through the top plate 3 and is fixedly installed with a screw rod 502, the two sets of threads on the surface of the screw rod 502 are rotated in opposite directions, and the top plate 3 is provided with a first guide rod 503 at the bottom end, and the outer surface of the screw rod 502 is respectively threadedly connected with the first slider 504 and the second slider 505, and the first slider 504 and the second slider 505 are both slidably connected to the outer surface of the first guide rod 503, and the first connecting rod 506 is fixedly installed on the front and rear sides of the first slider 504 through connecting members. A front protection plate 507 is fixedly installed on the right side of the first connecting rod 506, and a mounting plate 509 is fixedly installed on the top of the first connecting rod 506. A fixing plate 510 is fixedly installed on the top of the mounting plate 509, and two groups of second guide rods 511 are fixedly installed on the inner side of the fixing plate 510. The outer surfaces of the two groups of second guide rods 511 are both slidably installed with third sliders 512.

[0025] In this solution, firstly, driven by the motor 501, its output end drives the screw rod 502 to rotate, and the two sets of reverse threads designed on its surface enable the first slider 504 and the second slider 505 to move synchronously in opposite directions under the rotation of the screw rod 502. Secondly, the first guide rod 503 ensures the stability of the first slider 504 and the second slider 505 during the movement, and effectively prevents the deviation or shaking that may be caused by the rotation of the screw rod 502, thereby ensuring the movement accuracy and reliability of the entire protection mechanism 5. Furthermore, the front protection plate 507 is connected to the first slider 504 through the first connecting rod 506, and moves up and down with the movement of the first slider 504, thereby realizing front protection for the operator.

[0026] Reference Figure 1-4 As shown, two sets of movable connecting rods 508 are rotatably installed on the left side of the second slider 505, and the other ends of the two sets of movable connecting rods 508 are rotatably installed with fixed blocks 514. The inner sides of the two sets of fixed blocks 514 are fixedly installed with side baffles 515, and the two sets of fixed blocks 514 are fixedly installed on the top ends of the two sets of third sliders 512 through the second connecting rod 513.

[0027] In this solution, the design of the mounting plate 509 and the fixing plate 510 provides a stable installation foundation for the side protection structure, so that the side protection can be linked with the front protection to enhance the adaptability and flexibility of the protection mechanism 5, and the movement of the side baffle 515 utilizes the connection relationship between the movable link 508 and the second slider 505 and the fixed block 514. When the second slider 505 moves, the side baffle 515 can be moved through the cooperation of the second connecting rod 513, the second guide rod 511 and the third slider 512 through the transmission of the movable link 508, thereby realizing the protection of the sides of the surrounding personnel or equipment, meeting the needs of the staff.

[0028] The working principle of the present invention is as follows: when the stamping operation is about to begin, the operator starts the motor 501 through the control button 7 on the control platform 6. After the motor 501 is started, the screw rod 502 with two sets of reverse threads on the driving surface of its output end starts to rotate, so that the first slider 504 and the second slider 505 installed on the screw rod 502 can move synchronously along the axial direction of the screw rod 502 but in opposite directions. In order to ensure the smoothness and accuracy of the movement of the first slider 504 and the second slider 505, the first guide rod 503 provided at the bottom end of the top plate 3 provides a guiding effect for the first slider 504 and the second slider 505, effectively limiting their deviation or shaking during the movement, ensuring the stability and movement accuracy of the entire protection mechanism 5. As the first slider 504 moves up and down, the first connecting rod 506 is fixed to the The front protection plate 507 also moves up and down accordingly. When the stamping device 4 is working, it quickly and accurately blocks the front of the stamping area, providing front safety protection for the operator. At the same time, the mounting plate 509 and the fixed plate 510 serve as the basis for side protection, providing a basis for the linkage of the side baffle 515. When the second slider 505 moves with the rotation of the screw rod 502, the motion is transmitted to the two sets of fixed blocks 514 through the rotation connection of the movable connecting rod 508, thereby driving the side baffle 515 to move. In this process, the mutual cooperation of the second connecting rod 513, the second guide rod 511 and the third slider 512 ensures that the side baffle 515 can fit smoothly and accurately with the two sides of the front protection plate 507, thereby achieving effective protection of the side area of ​​the stamping machine and meeting the needs of the staff.
