A stamping platform is fixed on the frame, and the stamping platform is located above the double-sided die. A sliding hole is provided in the middle of the stamping platform.

[0004] For this rotary stamping die for cylindrical parts, although it solves the problem that the prior art needs to pick and place workpieces and repositioning the workpieces consumes a lot of time during the processing of parts, the above device has the problems of insufficient clamping stability of the workpiece by the traditional rotary stamping die for cylindrical parts and difficulty in ensuring the coincidence of the center of the workpiece and the axis of the rotating column. Therefore, corresponding improvements need to be made to the device. Summary of the Invention

[0005] The purpose of the present invention is to provide a rotary stamping die for cylindrical parts to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A rotary stamping die for cylindrical parts, including a processing table, a processing mechanism is arranged inside the processing table, a clamping mechanism is fixedly connected to the surface of the processing mechanism, an adjusting mechanism is fixedly connected to one end of the processing mechanism, and a stamping device is fixedly connected to the top of the processing table; The processing mechanism includes a rotating column, which is rotatably connected to the inside of the processing table. One end of the rotating column is fixedly connected to an electric disc, and the surface and the inside of the electric disc are fixedly connected. A rectangular column is arranged inside the electric disc. One end of the rectangular column is fixedly connected to a first spring, and one end of the first spring is fixedly connected to a T-shaped rod. A slider is fixedly connected to the surface of the T-shaped rod. An articulated rod is hinged to the inner side of the slider. One end of the articulated rod is hinged to a clamping strip. Circular rods are respectively fixedly connected to both sides of the clamping strip, and one end of each circular rod is slidably connected to the inside of the slider. A positioning plate is fixedly connected to the inner top of the rotating column. One end of the rectangular column is fixedly connected to a cross, and a circular ring is fixedly connected to the left end of the rotating column.

[0007] According to the above technical solution, a rectangular cavity is opened inside the rectangular column. The surface of the slider is slidably connected to the inside of the rectangular cavity. A through hole is opened at one end inside the rectangular column, and the surface of the T-shaped rod penetrates through the through hole opened at one end inside the rectangular column.

[0008] According to the above technical solution, positioning row holes are opened inside the positioning plate. The upper surface of the clamping strip matches the inside of the positioning row holes. A guide groove is opened inside the rotating column, and the four ends of the cross are respectively slidably connected to the inside of the guide groove.

[0009] According to the above technical solution, an opening is opened at the top of the rectangular column. The upper surface of the clamping strip is located inside the opening. The clamping strip is limited in the slider by the circular rod. Under this limiting mechanism, the clamping strip slides downward until the clamping strip disengages from the clamping position inside the positioning plate. This action of disengaging from the clamping position enables the rectangular column to obtain the freedom of movement.

[0010] According to the above technical solution, the clamping mechanism includes arc-shaped clamping plates. There are four arc-shaped clamping plates, and the four arc-shaped clamping plates are symmetrically arranged on the surface of the rotating column respectively. A limiting rod is slidably connected to the inside of one end of each arc-shaped clamping plate, and the bottom end of the limiting rod is fixedly connected to the surface of the rotating column. Articulated strips are respectively hinged to both ends of one side of the bottom of each arc-shaped clamping plate, and the bottom end of each articulated strip is hinged to a T-shaped block. A support block is arranged inside the rotating column. A hollow strip is rotatably connected to the inside of the bottom end of the support block. A cross bar is arranged inside the hollow strip. A second spring is fixedly connected to one end of the support block. An arc-shaped groove is opened on the surface of the circular ring. The bottom end of the hollow strip is hinged to the surface of the rectangular column, and the surface of the T-shaped block is slidably connected to the inside of the arc-shaped groove.

[0011] According to the above technical solution, a straight groove is opened inside the rotating column, the surface of the support block is slidably connected to the inside of the straight groove, one end of the second spring is fixedly connected to the inside of the straight groove, a hollow groove is opened inside the hollow strip, the surface of the cross bar is located inside the hollow groove, the hollow strip rotates, the hollow strip is connected to the support block, and then drives the support block to move inside the rotating column. During this process, the support block overcomes the elastic force of the second spring and drives the arc-shaped clamping plate to move. The arc-shaped clamping plate is supported and limited by the limiting rod and expands reversely towards the surface of the rotating column, finally realizing the firm clamping of the workpiece.

[0012] According to the above technical solution, the adjusting mechanism includes an arc seat, the arc seat is fixedly connected to the top of the back of the processing table, an arc block is slidably connected inside the arc seat, a limiting block is slidably connected inside the arc block, a T-shaped strip is fixedly connected inside the limiting block, a third spring is fixedly connected to the surface of the limiting block, an insertion strip is fixedly connected to one end inside the T-shaped strip, a rotating ring is fixedly connected to one end of the rotating column, a fourth spring is fixedly connected to one end of the rotating ring, a T-shaped rod is fixedly connected to one end of the fourth spring, a hemispherical block is fixedly connected to one end of the T-shaped rod, and an arc-shaped clamping strip is fixedly connected to the surface of the arc seat.

[0013] According to the above technical solution, a clamping hole is opened inside the arc-shaped clamping strip, the surface of the insertion strip is matched with the inside of the clamping hole, a limiting groove is opened inside the arc block, and the surface of the limiting block is slidably connected to the inside of the limiting groove.

[0014] According to the above technical solution, an arc-shaped slot is opened inside the arc seat, the surface of the arc block is slidably connected to the inside of the arc-shaped slot, a through hole is opened inside one end of the rotating ring, the T-shaped rod passes through the through hole opened inside one end of the rotating ring, and the insertion strip is reinserted into the arc-shaped clamping strip. In this way, the position of the hemispherical block inserted into the semi-circular groove on the arc block is successfully changed. Through this series of operations, the processing position on the surface of the workpiece is adjusted and the processing position is adjusted according to the radius size of the workpiece, so as to meet diverse processing requirements.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. For this rotary stamping die for cylindrical parts, through the provided processing mechanism, the cross is used to play a role of limiting and supporting inside the rotating column. It drives the hollow strip to rotate, the hollow strip is connected to the support block, and then drives the support block to move inside the rotating column. During this process, the support block overcomes the elastic force of the second spring and drives the arc-shaped clamping plate to move. The arc-shaped clamping plate is supported and limited by the limiting rod and expands reversely towards the surface of the rotating column, finally realizing the firm clamping of the workpiece, thereby ensuring that the center of the workpiece is approximately coincident with the axis of the rotating column, providing a prerequisite for subsequent precise processing.

[0016] 2. The rotary stamping die for cylindrical parts, through the set processing mechanism, pulls the T-shaped rod. This pulling action has an important conduction effect. The T-shaped rod is connected to the slider. When the T-shaped rod is pulled, the slider will move inside the rectangular column. The movement of the slider drives the movement of another slider connected to it. At the same time, the clamping bar will also move accordingly. The clamping bar is limited in the slider through a round rod. Under this limiting mechanism, the clamping bar slides downward until it disengages from the clamping position inside the positioning plate. This action of disengaging from the clamping position enables the rectangular column to obtain the freedom of movement, thereby realizing the corresponding clamping control.

[0017] 3. The rotary stamping die for cylindrical parts, through the set clamping mechanism, during clamping, the structural design of the arc-shaped clamping plate further ensures the stability of clamping. The arc-shaped clamping plate is connected to the T-shaped block through a hinge bar. Under the limiting action of the circular ring on the T-shaped block, when the arc-shaped clamping plate clamps the workpiece, it can provide more stable support, effectively preventing the workpiece from shaking or displacing during the processing, and ensuring the accuracy and quality of the processing.

[0018] 4. The rotary stamping die for cylindrical parts, through the set adjusting mechanism, after the insertion bar completely disengages from the inside of the arc-shaped clamping bar, the arc-shaped block can be slid to move to the corresponding position inside the arc seat. After determining the position, let the insertion bar re-engage into the inside of the arc-shaped clamping bar. In this way, the position of the hemispherical block inserted into the semi-circular groove on the arc-shaped block is successfully changed. Through this series of operations, the processing position on the surface of the workpiece is adjusted and the corresponding processing position is adjusted according to the radius size of the workpiece, so as to meet diverse processing requirements.

[0024] Further, an opening is opened at the top of the rectangular column 23, and the upper surface of the clamping strip 25 is located inside the opening. The hollow strip 37 is connected to the support block 35, thereby driving the support block 35 to move inside the rotating column 21. During this process, the support block 35 overcomes the elastic force of the second spring 36 and drives the arc-shaped clamping plate 31 to act. The arc-shaped clamping plate 31 is supported and limited by the limiting rod 32 and expands reversely towards the surface of the rotating column 21, finally realizing the firm clamping of the workpiece, thereby ensuring that the center of the workpiece is roughly coincident with the axis of the rotating column 21, providing a prerequisite for subsequent precise processing. Embodiment 2

[0025] Refer to Figures 1-9 and on the basis of Embodiment 1, it is further obtained that the clamping mechanism 3 includes arc-shaped clamping plates 31.

The arc-shaped clamping plate 31 is supported and limited by the limiting rod 32 and expands reversely towards the surface of the rotating column 21, finally realizing the firm clamping of the workpiece. Embodiment III

[0027] Refer to Figures 1-9 On the basis of Embodiment I, the adjusting mechanism 4 further includes an arc seat 41. The arc seat 41 is fixedly connected to the top of the back surface of the processing table 1. An arc block 42 is slidably connected inside the arc seat 41. A limiting block 43 is slidably connected inside the arc block 42. A T-shaped bar 44 is fixedly connected inside the limiting block 43. A third spring 441 is fixedly connected to the surface of the limiting block 43. An inserting bar 45 is fixedly connected to one end inside the T-shaped bar 44. One end of the rotating column 21 is fixedly connected to a rotating ring 46. One end of the rotating ring 46 is fixedly connected to a fourth spring 461. One end of the fourth spring 461 is fixedly connected to a T-shaped rod 47. One end of the T-shaped rod 47 is fixedly connected to a hemispherical block 48. An arc-shaped clamping strip 49 is fixedly connected to the surface of the arc seat 41. A clamping hole is formed inside the arc-shaped clamping strip 49. The surface of the inserting bar 45 is matched with the inside of the clamping hole. A limiting groove is formed inside the arc block 42. The surface of the limiting block 43 is slidably connected to the inside of the limiting groove.

[0028] Furthermore, an arc-shaped slot is formed inside the arc seat 41. The surface of the arc block 42 is slidably connected to the inside of the arc-shaped slot. A through hole is formed inside one end of the rotating ring 46. The T-shaped rod 47 penetrates through the through hole formed inside one end of the rotating ring 46. The stamping device 5 starts to process the surface of the workpiece. It should be noted that each time the processing is completed, the workpiece needs to be rotated by a certain angle to realize the processing of different parts of the workpiece. Here, the rotating action is driven by the electric disc 22. The electric disc 22 is connected to the workpiece. Through precise control, each time the workpiece is driven to rotate to a specific position. When the hemispherical block 48 is clamped into the semi-circular groove formed on one side of the arc block 42, the workpiece stops rotating. At this time, the stamping device 5 starts to process.

[0029] In actual operation, when this device is used, when processing a cylindrical workpiece, the first step is to clamp and fix the workpiece, and carefully put the cylindrical workpiece to be processed on the surface of the rotating column 21. This is the basic starting action of the entire processing flow, ensuring that the center of the workpiece roughly coincides with the axis of the rotating column 21, providing a prerequisite for subsequent precise processing. Then, the workpiece needs to be further firmly clamped. At this time, the T-bar 26 is pulled. This pulling action has an important conduction effect. The T-bar 26 is connected to the slider 24. When the T-bar 26 is pulled, the slider 24 will move inside the rectangular column 23. The movement of the slider 24 drives the movement of another slider 24 connected to it. At the same time, the clamping strip 25 will also move accordingly. The clamping strip 25 is limited in the slider 24 by the round rod 251. In this limit mechanism The clamping bar 25 slides downward until the clamping bar 25 is out of the clamping position inside the positioning plate 27. This action of disengaging from the clamping position allows the rectangular column 23 to be free to move. At this time, the rectangular column 23 can be moved to move inside the rotating column 21. The movement of the rectangular column 23 will produce a chain reaction. The rectangular column 23 is connected to the cross 28. During the movement, the cross 28 plays the role of limiting support inside the rotating column 21, which drives the hollow bar 37 to rotate. The hollow bar 37 is connected to the support block 35, and then drives the support block 35 to move inside the rotating column 21. In this process, the support block 35 overcomes the elastic force of the second spring 36 and drives the arc clamping plate 31 to move. The arc clamping plate 31 is supported and limited by the limiting rod 32, and expands in the opposite direction to the surface of the rotating column 21, and finally achieves a firm clamping of the workpiece. When clamping, the structural design of the arc clamping plate 31 further ensures the stability of clamping. The arc clamping plate 31 is connected to the T-shaped block 34 through the hinge strip 33. Under the limiting action of the circular ring 29, the T-shaped block 34 enables the arc clamping plate 31 to provide more stable support when clamping the workpiece, effectively preventing the workpiece from shaking or displacing during the processing, and ensuring the accuracy and quality of the processing. When the workpiece is clamped, it enters the processing link, and the stamping equipment 5 starts to process the surface of the workpiece. It is worth noting that each time the processing is completed, the workpiece needs to be rotated by a certain angle to realize the processing of different parts of the workpiece. The rotation action here is driven by the electric disc 22, which is connected to the workpiece. Through precise control, the workpiece is driven to rotate to a specific position each time. When the hemispherical block 48 is stuck in the semicircular groove opened on one side of the arc block 42, the workpiece stops rotating, and the stamping equipment 5 starts processing at this time; During the actual processing, according to different processing requirements, sometimes it is necessary to adjust the processing position on the surface of the workpiece, or adjust the corresponding processing position according to the radius size of the workpiece. At this time, the operation steps are as follows: First, pull the T-shaped bar 44 upward. The T-shaped bar 44 is connected to the insertion bar 45. During the pulling process, the insertion bar 45 disengages from the position inside the arc-shaped clamping bar 49. During this process, the T-shaped bar 44 also drives the limit block 43 to move inside the arc block 42. The limit block 43 plays a role in restricting the movement trajectory of the T-shaped bar 44 to ensure the accuracy of the operation. When the insertion bar 45 completely disengages from the inside of the arc-shaped clamping bar 49, the arc block 42 can be slid to move to the corresponding position inside the arc seat 41. After determining the position, let the insertion bar 45 re-engage inside the arc-shaped clamping bar 49. In this way, the position of the hemispherical block 48 inserted into the semi-circular groove on the arc block 42 is successfully changed. Through this series of operations, the adjustment of the processing position on the surface of the workpiece and the corresponding adjustment of the processing position according to the radius size of the workpiece are realized, so as to meet the diverse processing requirements.
