Description

Technical Field

[0001] The present application relates to the field of forging processing technology, and in particular to a punching device suitable for different forgings. Background Art

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. Punching operations are usually required during the subsequent processing of the workpieces. Commonly used hole processing equipment includes various types of drilling machines such as bench drilling machines, vertical drilling machines and CNC drilling machines. Among them, the vertical drilling machine is mainly composed of a spindle box, a column, a workbench and a base. The drill bit is installed under the spindle of the spindle box. The spindle box is equipped with a cooling system and a feed system. The cooling system is used to cool the drill bit, and the feed system is used to control the punching depth of the drill bit.

[0003] In the related art, the Chinese utility model patent with the authorization publication number CN217964886U discloses a punching device for forging, which includes a processing table, an equipment plate is fixedly connected to the top of the processing table through a support frame, two fixed hydraulic cylinders are arranged below the equipment plate, and the bottom ends of the output shafts of the two fixed hydraulic cylinders are provided with drive motors, and the driving motor rotating shaft is provided with a drill bit for drilling holes. Two sets of clamps are arranged on the top surface of the processing table, and the two sets of clamps are arranged oppositely. Each set includes two hydraulic cylinders and a clamping plate. The hydraulic cylinders are extended and retracted to drive the clamping plate to clamp the forging.

[0004] With respect to the above-mentioned related technologies, the inventors found that different forgings have different shapes, and the two sets of clamps in the above-mentioned technologies are only suitable for fixing some forgings with relatively regular shapes, such as plates, etc., while it is inconvenient to clamp some forgings with irregular shapes or to drill holes after clamping. Therefore, the types of forgings that can be clamped by the clamp are relatively limited, resulting in a relatively small scope of application of the punching device. Summary of the invention

[0005] In order to facilitate the clamping of different forgings and improve the application scope of the punching equipment, the present application provides a punching device suitable for different forgings.

[0006] The present application provides a punching device suitable for different forgings, which adopts the following technical solution:

[0007] A punching device suitable for different forgings includes a vertical drilling machine body, the vertical drilling machine body includes a base, a column is vertically arranged on the base, a spindle box is arranged on the top of the column, a drill bit is arranged below the spindle box, and also includes a flexible limit platform and a chain, the flexible limit platform is arranged on the column, the flexible limit platform includes a limit box, the top of the limit box is opened, a plurality of groups of elastic support members are fixedly connected in the limit box, the plurality of groups of elastic support members are closely arranged in a matrix in the limit box, and the chain passes through the top of the elastic support member and can be fixed at both ends.

[0008] By adopting the above technical scheme, before punching the forging, the forging is first fixed. When fixing, the forging is placed on the elastic support. At this time, the elastic support in contact with the forging is compressed by force, and the elastic support not in contact with the forging remains in its original state. Moreover, since the elastic support is closely arranged in a matrix, a depression matching the shape of the forging can be formed on the flexible limit table to stably limit the forging. At this time, the forging is restrained from above by a chain, thereby completing the fixation of the forging. Since the chain is a flexible part, different forgings can be conveniently fixed. By cooperating with the chain of the flexible limit table, the forging is first limited and then fixed, and forgings of different shapes can be fixed, thereby facilitating the clamping of different forgings and improving the application range of the punching equipment.

[0010] By adopting the above technical solution, after the forging is placed, the limiting columns in contact with the forging are compressed, and the limiting columns not in contact with the forging are not compressed, so that a shape compatible with the shape of the forging can be formed, thereby limiting the forging. After the forging is limited, the locking screw is rotated, and the locking screw drives the locking plate to press against the limiting columns. At this time, due to the fixation of the locking plate and the friction between the multiple limiting columns, the limiting columns are locked, thereby completing the limitation of the forging and improving the stability of the limitation of the forging.

[0016] By adopting the above technical solution, after the chain slides to adjust its position, the position of the first fixed block can be slid along the guide rod, so that the position of the hook is consistent with that of the chain, so as to facilitate locking the chain; at the same time, by setting a limit rod, the first fixed block is limited along the limit rod, and at the same time, the hook can be ensured to rotate along the guide rod, which is convenient for rotating the hook to hook the chain and for locking the hook, thereby facilitating locking the chain.

A longitudinal positioning mechanism 2 and a transverse positioning mechanism 3 are arranged below the spindle box 13, a drill bit 14 is arranged on the transverse positioning mechanism 3, and the transverse positioning mechanism 3 is arranged at the bottom of the longitudinal positioning mechanism 2. The longitudinal positioning mechanism 2 and the transverse positioning mechanism 3 are respectively used to drive the drill bit 14 to move longitudinally and transversely in the horizontal plane to locate the punching position. A flipping mechanism 4 is arranged on the column 12, and a flexible limit platform 5 is arranged on the flipping mechanism 4 to limit the forgings of different shapes. Two sets of chain locking mechanisms 6 are arranged on the flexible limit platform 5 to fix the forgings on the flexible limit platform 5. After the forging is fixed, the drill bit 14 is used to perform the punching operation on it, and the flipping mechanism 4 is used to flip the flexible limit platform 5 at various angles to facilitate the punching operation at different positions of the forging.

[0041] Reference Figure 2 The longitudinal positioning mechanism 2 includes a longitudinal positioning screw 21, a longitudinal slider 22 and a longitudinal drive motor 23. A longitudinal slide 24 is provided on the bottom surface of the spindle box 13. The longitudinal positioning screw 21 is rotatably connected in the longitudinal slide 24, and the axial direction of the longitudinal positioning screw 21 is parallel to the length direction of the longitudinal slide 24. The longitudinal slider 22 is threadedly connected to the longitudinal positioning screw 21 and slides in the longitudinal slide 24. The longitudinal drive motor 23 is fixedly connected to the front of the spindle box 13 and the rotating shaft passes through the spindle box 13 and is coaxially fixedly connected to the longitudinal positioning screw 21. The longitudinal slider 22 is set in a T shape, and the shape of the longitudinal slide 24 is set correspondingly to limit the longitudinal slider 22.

[0042] Reference Figure 2The transverse positioning mechanism 3 includes a transverse sliding box 31, a transverse positioning lead screw 32, a transverse slider 33 and a transverse driving motor 34. The transverse sliding box 31 is fixedly connected to the bottom surface of the longitudinal slider 22. The length direction of the transverse sliding box 31 is perpendicular to the axial direction of the longitudinal positioning lead screw 21. A transverse sliding groove 35 is provided on the bottom surface of the transverse sliding box 31 along its length direction. The transverse positioning lead screw 32 is rotatably connected in the transverse sliding groove 35 and its axial direction is parallel to the length direction of the transverse sliding groove 35. The transverse slider 33 is threadedly connected to the transverse positioning lead screw 32 and slides in the transverse sliding groove 35. The transverse driving motor 34 is fixedly connected to one end of the transverse sliding box 31 and its rotating shaft passes through the transverse sliding box 31 and is coaxially fixedly connected to the transverse positioning lead screw 32. The bottom surface of the transverse slide block 33 is fixedly connected with a feed cylinder 15, the feed cylinder 15 is axially arranged vertically, and the bottom end of the telescopic shaft of the feed cylinder 15 is fixedly connected with a drill drive motor 16, the rotating shaft of the drill drive motor 16 is arranged coaxially with the cylinder, and the drill 14 is fixedly connected to the bottom end of the rotating shaft of the drill drive motor 16. The feed cylinder 15 is extended and retracted to drive the drill 14 to rise and fall, so as to adjust the height of the drill 14, thereby adjusting the punching depth of the drill 14. The drill 14 drive cylinder is used to drive the drill 14 to rotate to complete the punching operation.

[0043] Before punching, the position of the drill bit 14 needs to be adjusted according to the position of the hole to be drilled on the forging. First, the longitudinal drive motor 23 is started, and the longitudinal drive motor 23 drives the longitudinal positioning screw 21 to rotate, thereby driving the longitudinal slider 22 to slide along the longitudinal slide 24, and the longitudinal slider 22 drives the transverse positioning mechanism 3 to slide, thereby driving the drill bit 14 to move in the longitudinal direction. After the longitudinal position is adjusted, the transverse drive motor 34 is started again, and the transverse drive motor 34 drives the transverse positioning screw 32 to rotate, thereby driving the transverse slider 33 to slide along the transverse slide 35, and the transverse slider 33 drives the drill bit 14 to move in the transverse direction, thereby moving to the position above the forging where the hole needs to be punched, and completing the positioning of the drill bit 14.

[0044] Reference Figure 1The flip mechanism 4 includes a first flip motor 41, which is fixedly connected to the column 12 through a mounting seat 42. The rotation axis of the first flip motor 41 passes through the column 12 and is coaxially fixedly connected to a first rotating rod 43. The rotation axis of the first flip motor 41 is parallel to the axial direction of the longitudinal positioning screw 21. A first fixed ring 44 is coaxially fixedly connected to the first rotating rod 43, and a connecting rod 45 is fixedly connected to the side wall of the first fixed ring 44. The connecting rod 45 is set in an L shape. The connecting rod 45 includes a cross bar 451 and a longitudinal bar 452. The cross bar 451 is fixedly connected to the side wall of the first fixed ring 44 and its length direction is perpendicular to the axial direction of the first fixed ring 44. The longitudinal bar 452 is fixedly connected to the other end of the cross bar 451 and its length direction is parallel to the axial direction of the first fixed ring 44. The other end of the longitudinal bar 452 is fixedly connected to a second fixed ring 46, and the axial direction of the second fixed ring 46 is perpendicular to the axial direction of the first fixed ring 44. A second flip motor 47 is fixedly connected to one end of the second fixed ring 46 away from the first fixed ring 44. The rotating shaft of the second flip motor 47 is coaxially arranged in the second fixed ring 46. A second rotating rod 48 is coaxially fixedly connected to the rotating shaft of the second flip motor 47. The other end of the second rotating rod 48 is fixedly connected to a support seat 49. The flexible limit platform 5 is fixedly connected to the top of the support seat 49.

[0045] Reference Figure 1 and Figure 3 The flexible limit table 5 includes a limit box 51, multiple groups of elastic support members 52 and a locking member 53. The limit box 51 is fixedly connected to the top of the support seat 49. The length direction of the limit box 51 is parallel to the axial direction of the longitudinal positioning screw 21. The top of the limit box 51 is open. Multiple groups of elastic support members 52 are closely arranged in a matrix in the limit box 51. The elastic support members 52 can be extended and retracted up and down. The locking member 53 is used to lock and fix the multiple groups of elastic support members 52. When the forging is placed on the surface of the multiple groups of elastic support members 52, the elastic support members 52 that contact the forging are compressed by force, while the remaining elastic support members 52 remain in an extended state because they do not contact the forging, thereby forming the shape of the forging in the multiple groups of elastic support members 52. At this time, the forging is locked by the locking member 53 to complete the limit of the forging.

[0046] Reference Figure 3 and Figure 4The elastic support member 52 includes a spring 521 and a limiting column 522. When the flexible limiting platform 5 is set horizontally, the spring 521 is set axially vertically. The bottom end of the spring 521 is fixedly connected to the bottom wall inside the limiting box 51. The limiting column 522 is coaxially fixedly connected to the top of the spring 521, and the limiting column 522 extends out of the limiting box 51. Since a plurality of limiting columns 522 are closely arranged in a matrix in the limiting box 51, when the forging is placed, some limiting columns 522 are compressed and some are not compressed, so that a shape that matches the shape of the forging can be formed, thereby limiting the forging. In order to avoid damage to the forging, the top of the limiting column 522 is set as an arc surface and is covered with a silicone cap 523, so as to protect the forging.

[0047] Reference Figure 3 and Figure 5 The locking member 53 includes a locking screw 531 and a locking plate 532. A sliding groove 533 is provided on an inner wall of the limit box 51 in the length direction. The sliding groove 533 is provided along the width direction of the limit box 51. The locking plate 532 is slidably connected in the sliding groove 533 along the direction in which the sliding groove 533 is provided. The thickness of the locking plate 532 is smaller than the width of the sliding groove 533. The locking screw 531 is rotatably connected to the side wall of the limit box 51 in which the sliding groove 533 is provided and passes through the side wall of the limit box 51 to be threadedly connected to the locking plate 532. The axial direction of the locking screw 531 is parallel to the width direction of the limit box 51. A limiting ring 534 is coaxially fixedly connected to the locking screw 531. A limiting groove 535 is correspondingly provided in the side wall of the limit box 51. The limiting groove 535 is located on the side of the sliding groove 533 away from the inner wall of the limit box 51. The limiting ring 534 is rotatably connected in the limiting groove 535. To facilitate the rotation of the locking screw 531 , one end of the locking screw 531 away from the locking plate 532 is fixedly connected to the rotating handle 536 .

[0048] After the forging is placed on the limiting column 522, the locking screw 531 is rotated, and the locking plate 532 moves toward the limiting column 522 until it is tightly pressed against the limiting columns 522. At this time, due to the fixation of the locking plate 532 and the friction between the limiting columns 522, the limiting columns 522 are locked, thereby completing the limitation of the forging.

[0049] Reference Figure 3 and Figure 5The two sets of chain locking mechanisms 6 are installed on the limit box 51, and the two ends of one set of chain locking mechanisms 6 are respectively arranged on the two side walls of the limit box 51 in the length direction, and the two ends of the other set of chain locking mechanisms 6 are respectively arranged on the two side walls of the limit box 51 in the width direction, and are used to restrain and fix the forging from above the flexible limit platform 5. The chain locking mechanism 6 includes two chains 61 and two sets of chain locking members 62. The two chains 61 and the two sets of chain locking members 62 are arranged one by one. The two chains 61 are used to restrain and fix the two ends of the forging, and the chain locking members 62 are used to lock the chains 61. Here, the chain locking mechanism 6 in which both ends of the chain 61 are respectively fixed on the two side walls of the limit box 51 in the length direction is described as an example. A guide groove 631 is provided on the side wall where the locking screw 531 is located on the limit box 51. The length direction of the guide groove 631 is parallel to the length direction of the limit box 51. Two guide blocks 632 are slidably connected in the guide groove 631. The two guide blocks 632 are respectively arranged corresponding to the two chains 61. The guide blocks 632 are fixedly connected to the limit blocks 633. The guide groove 631 is grooved corresponding to the limit blocks 633 so that the guide blocks 632 can slide in the guide groove 631. One end of the chain 61 is rotatably connected to the guide block 632. When the forging needs to be fixed, the chain 61 is restrained from above the forging, and the free end of the chain 61 is locked using the chain locking member 62. When the chain 61 is locked, the forging can be fixed. In order to prevent the chain 61 from damaging the surface of the forging, a silicone layer 612 is bonded to the side of the chain 61 that contacts the forging to protect the forging.

[0050] Reference Figure 3 and Figure 6, two fixing plates 641 are fixedly connected to the side of the limit box 51 away from the guide block 632, and a guide rod 642 and a limit rod 643 are fixedly connected between the two fixing plates 641. The guide rod 642 is located above the limit rod 643, and the length directions of the guide rod 642 and the limit rod 643 are parallel to the length direction of the limit box 51. The guide rod 642 is set as a round rod, and the limit rod 643 is set as a square rod. The chain locking member 62 includes a first fixing block 621 slidably connected to the guide rod 642 and a second fixing block 622 slidably connected to the limit rod 643. The first fixing block 621 and the second fixing block 622 are connected by a connecting plate 623. A rotating groove 624 is provided on the bottom surface of the first fixing block 621, and a hook 625 is provided in the rotating groove 624. The hook 625 rotates on the guide rod 642 and is slidably connected to the guide rod 642 with the first fixing block 621. The hook 625 is used to clamp the chain pin 611 at the free end of the chain 61. The top surface of the first fixed block 621 is threadedly connected with a first tightening screw 626. After the hook 625 clamps the chain pin 611, the first tightening screw 626 is tightened. The first tightening screw 626 pushes the hook 625 to rotate downward. When the hook 625 stops rotating, the chain 61 is locked, thereby locking the forging. In order to position the first fixed block 621 and the second fixed block 622, a second tightening screw 627 is threadedly connected to the connecting plate 623. The second tightening screw 627 is threadedly connected to the second fixed block 622, and the threaded hole on the second fixed block 622 is opened to the limit rod 643. When the second tightening screw 627 locks the second fixed block 622 on the limit rod 643, the first fixed block 621 and the second fixed block 622 are fixed, so as to maintain the stability of the chain 61 when the flexible limit platform 5 is flipped. In addition, the redundant chain 61 can be wound around the limiting rod 643 to facilitate the subsequent flipping operation of the forging.

[0051] Since the two groups of chain locking mechanisms 6 have the same structure and the only difference is the position, the other group of chain locking mechanisms 6 will not be described in detail here.

[0052] The implementation principle of a punching device suitable for different forgings in the embodiment of the present application is as follows: before punching the forging, the forging is first fixed. When fixing, the forging is placed on the limiting column 522. At this time, the limiting column 522 in contact with the forging is subjected to force reduction, and the limiting column 522 not in contact with the forging remains in its original state, thereby forming a depression matching the shape of the forging on the flexible limiting platform 5 to limit the forging. At this time, the guide block 632 is slid again to move the chain 61 to a position that is convenient for fixing the forging and does not affect drilling, and then the forging is restrained by the chain 61. The chain 61 in the appropriate direction and the number of chains 61 can be selected according to the shape and size of the forging. Through the cooperation of the flexible limiting platform 5 and the chain locking mechanism 6, it is convenient to clamp forgings of different shapes, and the scope of application of the punching device is improved.

[0053] Slide the connecting plate 623 until the hook 625 reaches the position of the chain 61, use the hook 625 to clamp the closest chain pin 611, and then rotate the first tightening screw 626 to make the hook 625 lock the chain 61, thus completing the locking of the forging. Then, lock the second tightening screw 627 to lock the first fixing block 621 and the second fixing block 622 on the limit box 51, further locking the forging.

[0054] Then the longitudinal drive motor 23 and the transverse drive motor 34 are started to adjust the longitudinal position and transverse position of the drill 14 respectively to complete the positioning of the punching position. The feed cylinder 15 is started to make the drill 14 drop to a suitable position, and the drill drive motor 16 is started to start the drill 14. The feed cylinder 15 drives the drill 14 to continuously drop and drill holes, thereby completing the punching operation on the upper side of the forging.

[0055] When it is necessary to drill holes around the forging, start the first flip motor 41 or the second flip motor 47 to flip the forging around to face upward, then adjust the drill bit 14 to a suitable position, and then perform the punching operation, so that the punching operation of multiple angles of the forging can be completed without disassembling the forging, which is convenient and quick.

[0056] In addition, after punching is completed, the flexible limit platform 5 can be flipped to a downward setting, and the limit column 522 is pushed. The limit column 522 will move due to the elastic effect, so that the debris mixed in the limit column 522 can fall off, which facilitates the cleaning of the equipment.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
