Description

Technical Field

[0001] This application relates to the field of punching die technology, and more specifically, to a high-efficiency sheet metal punching die and method. Background Technology

[0002] A punching die is a stamping die used to punch holes in a workpiece.

[0003] The prior art publication number CN212216766U provides a stamping die for the hand plate of a juicer. The device has a simple structure, is easy to operate, and can quickly and stably fix the hand plate. It can effectively avoid the hand plate from shaking out or jumping due to vibration during punching, reduce production scrap costs, meet usage requirements, and is beneficial to use.

[0004] However, existing stamping dies can only complete one punching action at a time. For workpieces requiring a large number of punches, it takes a long time to complete the punching process, resulting in low work efficiency.

[0005] However, when this device punches holes using a telescopic rod fixed to a fixed frame, it can only punch one sheet at a time. It needs to be moved to a different position before it can punch again. For workpieces requiring a large number of holes, it takes a long time to complete the punching process, resulting in low work efficiency.

[0006] In related technologies, the inventors believe that during punching, while punching one plate, the position of another plate can be adjusted, and the work on the other plate can be carried out directly after the previous plate is completed. At the same time, the previous plate can be repositioned again, which can improve the continuity of work, reduce the gap time, and effectively improve the efficiency of punching operations.

[0007] In view of this, we propose a high-efficiency sheet metal punching die and method. Summary of the Invention

[0032] Both the guide post 404 and the guide block 403 are fixedly provided with baffles 405 at their outer ends. One of the baffles 405 is slidably connected to the rear side wall of the upright plate 2, and the other baffle 405 is slidably connected to the front side wall of the movable plate 46.

[0033] In the above technical solution, the guide block 403, which is a rounded square structure, ensures that the machine head 3 is perpendicular to the fixed plate 1 during the movement.

[0034] As an optional solution to the technical solution of this application, the machine head 3 has a cavity 61 inside, and the adjustment component 6 includes an adjustment rod 62 rotatably disposed inside the cavity 61. One end of the adjustment rod 62 is fixedly provided with a hinge seat 63. The adjustment rod 62 and the hinge seat 63 are integrally formed and are V-shaped.

[0035] The inner end of the adjusting rod 62 is rotatably connected to two connecting rods 64 in a symmetrical structure via a pin. The connecting rods 64 are arranged in a V-shape, and one end of the two connecting rods 64 is rotatably connected to one end of the punching head 5 via a pin.

[0039] A connecting block B603 is rotatably provided at the lower end of the rotating column 601. The connecting block B603 is disposed between the two connecting rods 64 and is rotatably connected by a pin.

[0040] The upper outer wall of the rotating column 601 is provided with a drive groove 604 with an inclined structure. The drive groove 604 surrounds the outer wall of the rotating column 601 in a circumferential structure. A drive wheel 605 is slidably disposed inside the drive groove 604. The drive wheel 605 is fixedly disposed on the inner wall of the connecting block A602.

[0041] The machine head 3 also has a cavity 606 inside, and a second motor 607 is fixedly installed inside the cavity 606. The output axis of the second motor 607 extends downward and is coaxially connected and fixed to the rotating column 601.

[0042] In the above technical solution, the force on the punching head 5 can be effectively buffered during the punching process, thereby extending its service life.

[0043] Another objective of this invention is to provide a method for punching holes in a prototype, comprising the following steps:

[0044] The length of the punch head 5 extending out of the machine head 3 is adjusted according to the thickness of the plate to be punched. The second motor 607 is started to drive the rotating column 601 to rotate. Under the cooperation of the drive groove 604 and the drive wheel 605, the connecting block A602 moves axially along the rotating column 601, thereby realizing the adjustment of the length of the punch head 5 extending out of the machine head 3.

[0046] As the moving plate 46 moves, under the simultaneous limiting action of guide groove A401 and guide groove B402, the machine head 3 descends until the punching head 5 completes punching;

[0047] The first motor reverses at 45 degrees, and then operates on the plate to be punched on the other side. At the same time, the plate that has been punched is taken out and a new plate to be punched is placed, and so on.

[0080] The preferred embodiments of the present invention are described below with reference to the accompanying drawings, and the present invention will be further described in detail.

[0081] Reference Figure 1 and Figure 4 A high-efficiency sheet metal punching die, comprising:

[0082] Fixing plate 1;

[0083] Vertical plate 2, which is vertically fixed to the rear side of the upper end face of fixed plate 1;

[0084] The machine head 3 is slidably limited to the outside of the vertical plate 2 by the moving drive 4, and moves and changes position to punch holes;

[0085] The punching head 5 is slidably located in the head 3. The length of the punching head 5 extending out of the head 3 is adjusted by the adjusting component 6 to perform punching operations on plates of different thicknesses.

[0086] Reference Figure 4 The machine head 3 has an internal cavity 61. The adjustment assembly 6 includes an adjustment rod 62 rotatably disposed inside the cavity 61. A hinge seat 63 is fixedly disposed at one end of the adjustment rod 62. The adjustment rod 62 and the hinge seat 63 are integrally formed and have a V-shaped structure. Two connecting rods 64 are symmetrically rotatably disposed at the inner end of the adjustment rod 62 through a pin. The connecting rods 64 have a V-shaped structure. One end of the two connecting rods 64 is rotatably connected to one end of the punch head 5 through a pin. The hinge seat 63 and the two connecting rods 64 are connected by an adjustment component, which can adjust the extension length of the punch head 5 to adapt to plates of different thicknesses, thereby improving the practicality and application range of the equipment.

[0087] Reference Figure 5 The adjusting component includes a rotating column 601, with a connecting block A602 rotatably mounted on the upper end of the rotating column 601. The connecting block A602 is rotatably connected to the outer end of the hinge seat 63 via a pin. The lower end of the rotating column 601 is rotatably mounted with a connecting block B603, which is located between two connecting rods 64 and rotatably connected via a pin. During movement, the hinge seat 63 can be adjusted by simultaneously moving away from or closer to one side of the connecting rod 64.

[0088] The upper outer wall of the rotating column 601 is provided with a drive groove 604 with an inclined structure. The drive groove 604 surrounds the outer wall of the rotating column 601. A drive wheel 605 is slidably arranged inside the drive groove 604. The drive wheel 605 is fixedly arranged on the inner wall of the connecting block A602. The machine head 3 is also provided with a cavity 606. A second motor 607 is fixedly arranged inside the cavity 606. The output shaft of the second motor 607 is coaxially connected and fixed to one end of the rotating column 601. During the punching process, it can effectively buffer the force on the punching head 5, thereby extending its service life.

[0089] Reference Figure 1 Two symmetrical positioning grooves 7 are provided on the front side of the upper end of the fixing plate 1 to position the plate and facilitate the determination of the punching position.

[0090] Reference Figure 3The moving drive 4 includes a moving groove 41 formed on the outer wall of the upright plate 2. The moving groove 41 is T-shaped. A rack 42 is fixedly installed on the inner wall of the moving groove 41. A gear 43 is meshed with the outer wall of the rack 42. One end of the shaft of the gear 43 passes through the moving groove 41 and extends to the front side of the upright plate 2, where a moving plate 46 is rotatably installed. A housing 44 is slidably installed inside the moving groove 41. A first motor 45 is fixedly installed inside the housing 44. The output shaft of the first motor 45 extends out through the inner wall of the housing 44 and is coaxially fixedly connected to the gear 43. The moving drive 4 can drive the machine head 3 to switch positions, thereby continuously punching different plates. While punching another plate, another plate can be replaced or moved, thus achieving continuous punching and effectively improving work efficiency.

[0091] Reference Figure 2 The front outer wall of the upright plate 2 is fixedly equipped with two parallel limiting blocks 47 in an upper and lower structure. The limiting blocks 47 are slidably connected to the outer wall of the movable plate 46. Both sides of the movable plate 46 are inclined. The inner sides of the two limiting blocks 47 are also inclined, and the inclination angle is opposite to that of the movable plate 46. This allows the movable plate 46 to be restricted to the inner side of the two parallel limiting blocks 47. The two parallel limiting blocks 47 can restrict the movement direction of the movable plate 46, so that it can only perform linear movement in the left and right directions.

[0092] Reference Figure 1 and Figure 2 The moving drive 4 also includes a guide groove A401 opened on the outer wall of the front side of the upright plate 2. The guide groove A401 is set in an inverted U-shape. A guide block 403 is slidably arranged inside the guide groove A401. A guide groove B402 is opened on the outer wall of the moving plate 46. The guide groove B402 is set in a triangular structure. A guide post 404 is slidably arranged inside the guide groove B402. One end of the guide post 404 is connected and fixed to the machine head 3. The guide groove B402 and the guide groove A401 always overlap at one point, so that the machine head 3 can move along the structure of the guide groove B402 and also move along the guide groove A401 at the same time, satisfying both simultaneously.

[0093] The other end of the guide column 404 is connected and fixed to the guide block 403. Through the cooperation of the guide groove A401 on the upright plate 2 and the guide groove B402 on the moving plate, the machine head 3 can automatically descend when moving to both sides to punch the plate material positioned in the positioning groove 7. When it is necessary to punch the plate material, firstly, place the two plates to be punched into the positioning groove 7 on the fixed plate 1. Adjust the length of the punching head 5 according to the punching depth. Drive the second motor 607 to rotate through the controller, which drives the rotating column 601 to rotate. The drive groove 604 on the rotating column 601 restricts the drive wheel 605, so that the drive wheel 605 moves the connecting block A602. When the hinge seat 63 and the connecting rod 64 are close to each other, the punching head 5 extends out of the machine head 3.

[0094] At this time, the first motor 45 is driven to rotate, which drives the gear 43 to rotate. The gear 43 meshes with the rack 42, so that the gear 43 moves on the rack 42. This drives the moving plate 46 to move, which in turn drives the machine head 3 to move to different positions of the positioning slots 7.

[0095] While moving, the head 3 is simultaneously limited by both guide groove A401 and guide groove B402, causing it to descend until the punching head 5 completes punching, and then moves in the opposite direction to work on another plate.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention 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 of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
