Specific embodiments

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] During the punching process of the section steel, when the stamping is used for a long time and reaches a certain number of punching times, the cutting edge of the punch head will be blunt. When punching continues, the waste material will be wrapped by the waste material that has undergone extrusion and stretching deformation, causing the punching waste material to be connected to the punch head and be carried out of the section steel punching with the movement of the punch head, affecting the normal progress of subsequent punching processing. The waste material from the section steel punching falls from the punch press main seat to the ground. As the processing operation progresses, the waste material accumulates on the ground, and it is necessary for workers to collect and clean the waste material. The cleaning process is labor-consuming and affects production efficiency.

[0030] Based on this, please refer to Figures 1 - 10, in the embodiment of the present invention, a punching device for textile machine accessories includes a support frame 10, an adjusting mechanism 20, a punching table 30, a punching mechanism 40 and a material removing mechanism 60. The punching table 30 is connected to the support frame 10 and is used to place the profiled steel 50 to be punched. A driver 34 is arranged on the punching table 30, and the driver 34 is used to control the sliding of the profiled steel 50 along the punching table 30, so that the profiled steel 50 reaches the preset punching position and the profiled steel 50 moves away from the punching position after punching is completed; the adjusting mechanism 20 includes a first adjusting screw 21, a second adjusting screw 22, a first lifting seat 24 and a second lifting seat 25. The first adjusting screw 21 and the second adjusting screw 22 are arranged on the left and right sides of the punching table 30, and the first lifting seat 24 and the second lifting seat 25 are arranged on the upper and lower sides of the punching table 30. As Figure 1 shown, the first lifting seat 24 is arranged on the upper side of the punching table 30, and the second lifting seat 25 is arranged on the lower side of the punching table 30. The first adjusting screw 21 and the second adjusting screw 22 are used to drive the first lifting seat 24 and the second lifting seat 25 to move, so that the first lifting seat 24 and the second lifting seat 25 move towards or away from the punching table 30. In the embodiment of the present application, during the punching stage, when the first lifting seat 24 and the second lifting seat 25 move towards the punching table 30, after punching is completed, the first lifting seat 24 and the second lifting seat 25 move away from the punching table 30;

[0031] In the embodiment of the present application, the punching mechanism 40 is installed on the first lifting seat 24. The punching mechanism 40 includes a puncher 41 and a punch head 42 connected to the puncher 41. After the first lifting seat 24 moves towards the punching table 30 and reaches the preset punching position, the puncher 41 drives the punch head 42 to impact the profiled steel 50 to form a hole with a preset specification on the processing surface of the profiled steel 50. The hole can be a round hole, a polygonal hole, a special-shaped hole, etc.

[0032] Please refer to Figure 8 , in the embodiment of the present application, the punch head 42 includes a punch rod 421 and a cleaning block 422 arranged on the side of the punch rod 421. The cleaning block 422 has a certain distance from the lower end of the punch rod 421. The cleaning block 422 is made of a flexible material. During punching, the lower end of the punch rod 421 impacts the profiled steel 50, and the residual material falls off to form a hole. After the punch rod 421 continues to move down, the cleaning block 422 enters the hole to clean the formed hole.

[0033] Please refer to Figure 4, the material removing mechanism 60 is installed on the second lifting seat 25. The material removing mechanism 60 is used to recover the residual materials that fall during the punching operation. The material removing mechanism 60 includes a baffle 61, a lifting column 62 and a housing 63. The lifting column 62 is slidably installed on the housing 63. One end of the lifting column 62 is connected to the bottom of the housing 63 through a connecting spring 64, and the other end of the lifting column 62 is connected to the baffle 61. A storage cavity for storing residual materials is formed inside the lifting column 62. A feeding port 611 for the residual materials to fall into the storage cavity is formed on the baffle 61. During punching, the second lifting seat 25 drives the material removing mechanism 60 to move towards the bottom of the punching table 30. When the baffle 61 of the material removing mechanism 60 is in close contact with the punching table 30, the residual materials fall into the storage cavity inside the lifting column 62 along the feeding port 611. It should be noted that in order to ensure that the residual materials can fall into the feeding port 611, an opening is provided at the punching position on the punching table 30, and the residual materials fall into the feeding port 611 along the opening;

[0034] Further, in the embodiment of the present application, a sliding groove 631 is formed on the inner wall of the housing 63. A piston slider 632 is slidably installed inside the sliding groove 631. The piston slider 632 is fixedly connected to the lifting column 62. A through hole 621 is formed on the side wall of the lifting column 62. The through hole 621 is communicated with the storage cavity, and the setting position of the through hole 621 is higher than the setting position of the piston slider 632. After the baffle 61 is in close contact with the punching table 30, the second lifting seat 25 continues to move towards the punching table 30. At this time, the lifting column 62 compresses the connecting spring 64 and moves towards the bottom of the housing 63. The space between the piston slider 632 and the top of the sliding groove 631 increases, so that a negative pressure is generated in this space and inside the storage cavity, separating the small-volume debris and sundries in the residual materials from the punch 42 and entering the storage cavity, preventing some of the residual materials from being insufficiently separated from the punch 42, and at the same time collecting the residual materials uniformly, improving the collection efficiency and completion degree of the residual materials.

[0035] Please refer to Figures 9 - 10 , in the embodiment of the present application, an installation port is provided on the second lifting seat 25. A movable seat 251 is rotatably installed in the installation port. The outer end of the movable seat 251 is connected to the second lifting seat 25 through a fixing bolt 252. The housing 63 is fixedly connected to the movable seat 251. During the punching operation, the movable seat 251 is rotated to a horizontal position parallel to the second lifting seat 25, and the movable seat 251 is fixed by the fixing bolt 252. When discharging, the fixing bolt 252 is removed and the movable seat 251 is rotated to discharge the residual materials from the storage mechanism 60.

[0036] Please refer to again Figure 1, the support frame 10 includes a front beam 11 and a rear beam 12. The front beam 11 and the rear beam 12 are fixedly connected by a cross beam 13. The first adjusting screw 21 and the second adjusting screw 22 are rotatably installed on the front beam 11; one ends of the first adjusting screw 21 and the second adjusting screw 22 are both equipped with first synchronous pulleys, and the two first synchronous pulleys are driven by a first synchronous belt 23; the first adjusting screw 21 and the second adjusting screw 22 have the same structure, and external thread segments with opposite helix directions are provided on both the upper and lower sides;

[0037] A driving mechanism 70 for controlling the rotation of the second adjusting screw 22 is further provided on the front beam 11. As Figure 3 shown, the driving mechanism 70 includes a driving motor 71, a first bevel gear 73, a second bevel gear 74, a third bevel gear 75 and a driving box 72. The driving box 72 is rotatably connected to the second adjusting screw 22, and the driving box 72 is used to protect the first bevel gear 73, the second bevel gear 74 and the third bevel gear 75; the first bevel gear 73 is fixedly installed on the upper side of the second adjusting screw 22, the third bevel gear 75 is fixedly installed on the lower side of the second adjusting screw 22, and both the first bevel gear 73 and the third bevel gear 75 are semi-bevel gear structures. The second bevel gear 74 is fixedly connected to the output end of the driving motor 71, and the second bevel gear 74 meshes with the first bevel gear 73 and the third bevel gear 75 respectively. The driving motor 71 controls the rotation of the second bevel gear 74. The second bevel gear 74 intermittently meshes with the first bevel gear 73 and the third bevel gear 75. When the second bevel gear 74 meshes with the first bevel gear 73, the second adjusting screw 22 rotates in a first direction, and the first lifting seat 24 and the second lifting seat 25 move towards the punching table 30. When the second bevel gear 74 meshes with the third bevel gear 75, the second adjusting screw 22 rotates in a second direction, and the first lifting seat 24 and the second lifting seat 25 move away from the punching table 30 and return to the initial position to prepare for the punching operation in the next cycle.

[0038] Please refer to Figure 1 and Figures 5 - 7 , a frame 32 is installed on the side of the punching table 30. A rotating shaft 33 is rotatably installed on the frame 32. The driver 34 is fixedly connected to the rotating shaft 33. The driver 34 includes a housing 341 and at least one pressing block 342 rotatably installed on the housing 341. The head of the pressing block 342 (the end in contact with the profiled steel 50) is an elastic structure. When the rotating shaft 33 controls the driver 34 to rotate forward ( Figure 6 clockwise rotation in

[0039] Second synchronous belt pulleys are installed on both the first adjusting screw rod 21 and the second adjusting screw rod 22, and a second synchronous belt pulley is also fixedly installed on the rotating shaft 33. The second synchronous belt pulleys on the first adjusting screw rod 21 and the second adjusting screw rod 22 are connected by a second synchronous belt to the second synchronous belt pulley on the same-side rotating shaft 33 for controlling the rotation of the rotating shaft 33.

[0040] Further, in the embodiment of the present application, the housing 341 is provided with a limiting mechanism 344. The limiting mechanism 344 includes a limiting groove 3441 opened on the housing 341, a limiting slider 3444 arranged at one end of the limiting groove 3441, and an electromagnet 3442 arranged at the other end of the limiting groove 3441. The electromagnet 3442 is connected to the limiting slider 3444 through a limiting spring 3443. The limiting slider 3444 is connected to the pressing block 342. When the second adjusting screw rod 22 rotates in the first direction, the driver 34 rotates forward to control the movement of the profiled steel 50 until the profiled steel reaches the preset punching position. The punching mechanism 40 punches at the preset position. After punching is completed, the second adjusting screw rod 22 rotates in the second direction, and the driver 34 rotates reversely. The pressing block 342 is squeezed by the side of the profiled steel 50, and the limiting slider 3444 slides along the limiting groove 3441 towards the electromagnet 3442. The profiled steel 50 remains stationary on the punching table 30 under the action of static friction force, waiting for the next cycle of punching operation.

[0041] Still further, in the embodiment of the present application, a plurality of installation grooves 343 are opened inside the housing 341, and a pressing block 342 is arranged inside each installation groove 343. The limiting slider 3444 is made of iron material. Before punching, some of the electromagnets 3442 are energized to make some of the pressing blocks 342 retract into the installation grooves 343, thereby controlling the number of pressing blocks 342 in contact with the profiled steel 50, controlling the moving distance of the profiled steel 50, and adjusting the distance between the formed holes on the profiled steel 50.

[0042] In summary, the present invention is provided with a material removing mechanism for collecting punching residues. During punching operation, negative pressure is generated inside the material removing mechanism, so that small-volume debris and sundries in the residues are separated from the punch and enter the storage cavity, preventing some residues from being insufficiently separated from the punch. At the same time, the residues are collected uniformly, improving the collection efficiency and completion degree of the residues. The present invention also provides a driver for controlling the movement of the profiled steel on the punching table. The driver can adjust the moving distance of the profiled steel on the punching table according to the preset punching spacing, so that the profiled steel accurately reaches the preset punching position, improving the punching accuracy.
