Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and specifically to a stamping part fixing fixture. Background Technology

[0002] Stamping is a process in which external force is applied to sheet metal, strip, tube, and profile by a punch press and a die to cause plastic deformation or separation, thereby obtaining a workpiece of the required shape and size.

[0003] Chinese Patent Publication No. CN221848445U discloses a stamping part fixing structure, including a stamping frame, which is a rectangular frame structure. A stamping cylinder is installed on the stamping frame, and a mounting base is located in the middle of the stamping frame. A mold fixing plate is connected to the telescopic end of the stamping cylinder; an upper stamping mold is connected to the mold fixing plate. This utility model relates to the field of stamping processing technology. The stamping part fixing structure uses a roller structure for switching between workstations. Multiple pressure seats for workstations are fixed to the outside of the rollers for fixing the workpieces during the stamping process. At the same time, a separation unloading groove is arranged on one side of the pressure seats to separate the stamped workpieces and the frame. This structure is suitable for fixing a single workpiece and improves the adaptability of the stamping device.

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] Example 1:

[0054] like Figures 1 to 5 As shown, this utility model provides a stamping part fixing fixture, including: a bracket 1 and an upper stamping die 2 slidably mounted on the bracket 1 for stamping workpieces, a stamping cylinder 3 arranged on the bracket 1 for controlling the lifting and lowering of the upper stamping die 2, the output end of the stamping cylinder 3 being arranged above the upper stamping die 2, a pressure seat 4 rotatably mounted inside the bracket 1 for placing the stamping workpieces, and a drive structure arranged on the pressure seat 4 for controlling the rotation of the pressure seat 4.

[0055] The pressure bearing seat 4 includes several positioning grooves 401 and several mold grooves 405 formed inside the pressure bearing seat 4. The positioning grooves 401 and mold grooves 405 located on the same side are interconnected. The positioning grooves 401 can be used to place the stamping plate. During stamping, part of the workpiece will be pressed into the mold groove 405 to form a specific shape.

[0056] The driving structure includes a motor 402 arranged on the bracket 1, the output end of the motor 402 passing through the bracket 1 and arranged on one side of the pressure seat 4, a limiting ring 403 arranged on one side of the pressure seat 4, and an annular limiting groove 404 opened inside the bracket 1. The limiting ring 403 is rotatably installed in the annular limiting groove 404. When the motor 402 is turned on, its output end can drive the pressure seat 4 to rotate. When the pressure seat 4 rotates, it can drive the limiting ring 403 to rotate in the annular limiting groove 404, thereby preventing the position of the pressure seat 4 from shifting. The continuously rotating pressure seat 4 can drive the positioning groove 401 and the workpiece inside to move in a circular motion.

[0057] Example 2:

[0058] Based on Example 1, in order to facilitate the placement of the stamped workpiece into the positioning groove 401, and to eliminate the need for workers to reach between the upper stamping die 2 and the pressure seat 4, a material pushing structure for pushing materials is arranged on the bracket 1.

[0059] The pushing structure includes a material box 5 arranged inside the bracket 1 and corresponding to the positioning groove 401, a pushing plate 501 slidably installed inside the material box 5, a pushing cylinder 502 arranged on one side of the material box 5, the output end of the pushing cylinder 502 passing through the material box 5 and arranged on one side of the pushing plate 501, a feeding hole 503 opened on the material box 5 for inserting the stamping plate, and a limiting component arranged on the pressure seat 4 and the material box 5 for limiting the position of the workpiece. In use, the stamping plate is inserted into the material box 5 through the feeding hole 503, and then the pushing cylinder 502 is turned on, so that its output end drives the pushing plate 501 to move, so that the pushing plate 501 pushes the stamping workpiece into the positioning groove 401.

[0060] Specifically, the limiting component includes an arc-shaped baffle plate 504 arranged on the material box 5 and several suction magnets 505 arranged inside the corresponding positioning groove 401 to hold the metal stamping plate. The suction magnets 505 can hold the metal stamping workpiece. During the movement of the metal stamping workpiece, the outer side of the pressure seat 4 is blocked by the arc-shaped baffle plate 504. With the attraction of the suction magnets 505, the workpiece can be prevented from falling out of the positioning groove 401 when the pressure seat 4 rotates.

[0061] Example 3:

[0062] Based on Example 1, in order to prevent the stamped workpiece from getting stuck inside the mold groove 405, a stripping structure for assisting workpiece unloading is arranged inside the pressure seat 4. The stripping structure is used in conjunction with the driving structure.

[0063] The material removal structure comprises several components. Each component includes a fixed seat 6 mounted on the inner wall of the pressure seat 4, a push rod 601 slidably mounted inside the pressure seat 4 and the fixed seat 6, a fixed shaft 602 rotatably mounted inside the pressure seat 4, and a linkage cam 603 fixedly sleeved on the fixed shaft 602. The push rod 601 contacts the outer surface of the linkage cam 603. The fixed shaft 602 is mounted on the bracket 1. The linkage cam 603 is rotatably mounted inside the pressure seat 4 and rotates around the fixed shaft 602 during the rotation of the pressure seat 4. The fixed shaft 602 rotates, which in turn drives the corresponding fixed seat 6 to rotate, thereby driving the push rod 601 to rotate around the linkage cam 603. When the pressure seat 4 drives the stamped workpiece to rotate downward, the linkage cam 603 is more convex in the downward position, so the push rod 601 will slide under the pressure of the linkage cam 603 during the rotation. The sliding push rod 601 will squeeze the stamped workpiece in the mold groove 405, causing the workpiece to separate from the mold groove 405 and the suction magnet 505.

[0064] The stripping structure also includes a reset assembly arranged on the push rod 601 for moving the push rod 601 to reset it.

[0065] Specifically, the reset assembly includes a pressing plate 604 fixedly sleeved on the push rod 601, and a spring 605 arranged between the fixed base 6 and the pressing plate 604 to push the pressing plate 604 toward the linkage cam 603. When the push rod 601 is pressed by the linkage cam 603, it will drive the pressing plate 604 to move, and the pressing plate 604 will press the spring 605, causing the spring 605 to compress and store energy. When the push rod 601 disengages from the protruding position of the linkage cam 603, the compressed spring 605 will push the pressing plate 604 to move and reset.

[0066] Working principle:

[0067] In use, the stamped sheet is inserted into the material box 5 through the feeding hole 503. Then, the pusher cylinder 502 is turned on, causing its output end to drive the pusher plate 501 to move. The pusher plate 501 pushes the stamped workpiece into the positioning groove 401. The metal stamped workpiece can be attracted by the suction magnet 505. After the feeding is completed, the motor 402 can be turned on, causing its output end to drive the pressure seat 4 to rotate. When the pressure seat 4 rotates, it can drive the limiting ring 403 to rotate in the annular limiting groove 404, thereby preventing the position of the pressure seat 4 from shifting. The continuously rotating pressure seat 4 can drive the positioning groove 401 and the workpiece inside to move in a circular motion. During the movement of the metal stamped workpiece, the outer side of the pressure seat 4... The workpiece is prevented from detaching from the positioning groove 401 when the pressure seat 4 rotates due to the shielding of the arc-shaped baffle plate 504 and the attraction of the suction magnet 505. The continuously rotating pressure seat 4 will drive the metal stamping workpiece to rotate to the bottom of the upper stamping die 2. At this time, the upper stamping die 2 can be lowered and pressed on the pressure seat 4 by the stamping cylinder 3 to perform stamping operation on the workpiece. During the stamping process, part of the workpiece will be pressed into the die groove 405 to form a specific shape. During the process, a new workpiece can be added into the feeding hole 503 and the pressure seat 4 can be controlled to rotate for continuous stamping operation. After the stamping is completed, the workpiece moves to the bottom under the continuous rotation of the pressure seat 4 and detaches from the bottom.

[0068] During the rotation of the pressure seat 4, it rotates around the fixed shaft 602, simultaneously driving the corresponding fixed seat 6 to rotate circumferentially. This, in turn, causes the push rod 601 to rotate circumferentially around the linkage cam 603. When the pressure seat 4 rotates the stamped workpiece downwards, the linkage cam 603, being more convex downwards, causes the push rod 601 to slide inside the fixed seat 6 and the pressure seat 4 during its circumferential motion due to the compression of the linkage cam 603. The sliding push rod 601 then drives the pressing plate 604 to move, which in turn compresses the spring 605. The spring 605 is compressed and stores energy, while the continuously moving push rod 601 squeezes the stamped workpiece in the mold groove 405, causing the workpiece to separate from the mold groove 405 and the suction magnet 505, assisting in the workpiece unloading and preventing it from getting stuck in the mold groove 405. Then, the circularly moving push rod 601 will disengage from the protruding position of the linkage cam 603. At this time, the compressed spring 605 will push the extrusion plate 604 to move and reset, causing the extrusion plate 604 to drive the push rod 601 to press against the surface of the linkage cam 603, and at the same time, the push rod 601 will move and reset so that the workpiece can be placed into the mold groove 405 again.

[0069] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
