Description

Technical Field

[0001] This utility model relates to the field of rotating platform technology, and in particular to a rotating material tray self-locking structure for a punch press. Background Technology

[0002] The rotary tray of a punch press is an important component of the punch press equipment. It is usually composed of a tray body, a drive unit, a positioning device, etc. It is usually a platform for placing workpieces, and is usually round or square. Depending on the different punch press models and processing requirements, its size and material will vary. For example, the rotary tray of some small punch presses may be about tens of centimeters in diameter and made of aluminum alloy, which is lightweight and easy to rotate; while the tray of large punch presses may be several meters in diameter and made of high-strength steel to withstand the greater weight of the workpiece and the punching force.

[0003] A search revealed that Chinese patent CN221493829U discloses a "rotary stamping device". This device adopts a structural design with a central replaceable pad and a work plate. By installing work plates of different specifications, the specifications of nuts can be quickly changed. Each work plate slot is distributed on the outer edge of the work plate and can accommodate multiple nuts at the same time without the need for individual placement, which improves stamping efficiency to a certain extent.

[0004] However, based on the analysis of existing technologies, this patent has certain defects. In actual use, the rotating disk of the device lacks a structure that can lock the angle of the rotating disk. During the punching operation, the upper die and the lower die on the rotating disk will generate a large impact force and vibration. Due to the lack of an effective self-locking structure, this impact force and vibration can easily cause the rotating disk to deviate, thereby affecting the positioning accuracy of the rotating disk and making it inconvenient to use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a self-locking structure for a rotating material tray of a punch press, which solves the technical problem of inconvenient use of existing rotating trays.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A rotating tray self-locking structure for a punch press includes a base, wherein rectangular slots are symmetrically formed inside the base;

[0010] Both rectangular slots are equipped with self-locking structures inside;

[0011] The self-locking structure includes electric push rods, with U-shaped frames fixedly installed on the side walls of the output shafts of the two electric push rods, and symmetrically fixedly installed locking blocks on the side walls of the two U-shaped frames. A servo motor is embedded and fixedly installed inside the base, and the servo motor is located between the electric push rods. A material tray body is fixedly installed on the output shaft of the servo motor. Multiple locking slots are symmetrically opened inside the material tray body, and each locking slot is located below the locking block and engages with the locking block.

[0012] Preferably, the output shafts of both electric push rods can be driven by a U-shaped frame to engage the locking blocks into the slots. The upper end of the material tray body is symmetrically fixed with lower molds, and both lower molds are located between the slots.

[0013] Preferably, each of the card blocks has a storage slot inside, a fixed shaft is fixedly installed inside each storage slot, a damping bearing is provided on the circumferential surface of each fixed shaft, the inner ring of each damping bearing is fixedly installed with the fixed shaft, a rotating rod is fixedly installed on the outer ring of each damping bearing, and an air nozzle is provided at the lower end of each rotating rod, with each air nozzle partially exposed above the rotating rod.

[0014] Preferably, a plurality of support pulleys are symmetrically fixedly installed on the upper end of the base, and each support pulley is in contact with the bottom of the material tray body.

[0015] (III) Beneficial Effects

[0016] Firstly, by setting a self-locking structure, the operator can open the electric push rod, which causes the output shaft of the electric push rod to drive the U-shaped frame and the clamping block to move down and into the clamping slot. This allows the upper and lower dies of the punch press to counteract the radial displacement trend during processing, ensuring the rotation accuracy of the material tray body and avoiding affecting the rotation angle of its servo motor.

[0017] Secondly, by setting up air nozzles, the operator can rotate a rotating rod, which generates a radial force to rotate around the center of a fixed axis, thereby driving the air nozzles to rotate until they move above the rotation path of the lower mold. This allows for air cleaning of the processed workpiece surface. During the punching process, impurities such as iron filings, metal powder, and oil stains may remain on the workpiece surface. The high-pressure airflow from the air nozzles can directly act on the workpiece surface, blowing away these impurities and keeping the workpiece surface clean. This helps improve the appearance quality of the workpiece and avoids the impact of impurity residue on subsequent surface treatment processes. Attached Figure Description

[0024] This application provides a self-locking structure for a rotating material tray of a punch press, effectively solving the technical problem of inconvenient use of existing rotating trays. By setting a self-locking structure, the operator can open the electric push rod, causing its output shaft to drive the U-shaped frame and the clamping block to descend and move into the clamping slot. This counteracts the radial displacement trend during subsequent punching, ensuring the rotational accuracy of the material tray body and preventing interference with the rotation angle of its servo motor. Furthermore, by setting an air nozzle, the operator can rotate a rotating rod, causing it to generate a radial force and rotate around the center of a fixed shaft, thereby rotating the air nozzle until it moves above the rotation path of the lower die. This allows for air cleaning of the processed workpiece surface. Since iron filings, metal powder, oil, and other impurities remain on the workpiece surface during punching, the high-pressure airflow from the air nozzle directly acts on the workpiece surface, blowing away these impurities and keeping the workpiece surface clean. This helps improve the appearance quality of the workpiece and prevents impurities from affecting subsequent surface treatment processes.

[0025] Example

[0026] like Figure 1 - Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem of the inconvenience of using existing rotating disks. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a rotating material tray self-locking structure for a punch press, including a base 11, with rectangular slots 12 symmetrically opened inside the base 11;

[0028] Both rectangular slots 12 are equipped with self-locking structures inside;

[0029] The self-locking structure includes electric push rods 13, U-shaped frames 14 are fixedly installed on the side walls of the output shafts of the two electric push rods 13, and locking blocks 15 are symmetrically fixedly installed on the side walls of the two U-shaped frames 14. A servo motor 16 is embedded and fixedly installed inside the base 11. The servo motor 16 is located between the electric push rods 13. A material tray body 17 is fixedly installed on the output shaft of the servo motor 16. Multiple locking slots 18 are symmetrically opened inside the material tray body 17. Each locking slot 18 is located below the locking block 15, and each locking slot 18 engages with the locking block 15.

[0030] By setting a self-locking structure, the operator can open the electric push rod 13, which causes the output shaft of the electric push rod 13 to drive the U-shaped frame 14 and the clamping block 15 to descend and move into the clamping slot 18. This allows the upper and lower dies of the punch press to counteract the radial displacement trend during subsequent processing, ensuring the rotation accuracy of the material tray body 17 and avoiding affecting the rotation angle of its servo motor 16.

[0031] The output shafts of the two electric push rods 13 can be driven by the U-shaped frame 14 to drive the locking block 15 into the slot 18. The upper end of the material tray body 17 is symmetrically fixed with the lower mold 19. The two lower molds 19 are located between the slots 18. Each locking block 15 has a storage slot 26 inside. Each storage slot 26 has a fixed shaft 21 fixedly installed inside. Each fixed shaft 21 has a damping bearing 22 on its circumferential surface. The inner ring of each damping bearing 22 is fixedly installed with the fixed shaft 21. The outer ring of each damping bearing 22 is fixedly installed with a rotating rod 23. Each rotating rod 23 has an air nozzle 24 at its lower end. Each air nozzle 24 is partially exposed above the rotating rod 23.

[0032] By setting the air nozzle 24, the operator can rotate the rotating rod 23, causing the rotating rod 23 to generate a radial force and rotate around the center of the fixed shaft 21, thereby driving the air nozzle 24 to rotate until the air nozzle 24 moves above the rotation path of the lower mold 19. This allows for air cleaning of the surface of the processed workpiece. Since iron filings, metal powder, oil stains and other impurities remain on the surface of the workpiece during the punching process, the high-pressure airflow from the air nozzle 24 can directly act on the surface of the workpiece, blowing away these impurities and keeping the surface of the workpiece clean. This helps to improve the appearance quality of the workpiece and avoids the impact of impurity residue on subsequent surface treatment processes.

[0033] Multiple support pulleys 25 are symmetrically fixedly installed on the upper part of the base 11, and each support pulley 25 is in contact with the bottom of the tray body 17;

[0034] By setting up the support pulley 25, the material tray body 17 can rotate on the support pulley 25 when it rotates, and at the same time, the support pulley 25 will roll, which can greatly improve the stability of the material tray body 17.

[0035] Working principle:

[0036] In the first step, when using it, the operator can first put the blank workpiece into one of the lower molds 19, and then rotate the rotating rod 23 so that the rotating rod 23 generates a radial force to rotate around the center of the fixed shaft 21, thereby driving the air nozzle 24 (the air pipe of the air nozzle 24 is connected to an external air pump) to rotate until the air nozzle 24 moves above the rotation path of the lower mold 19.

[0037] The second step involves the operator activating the servo motor 16, causing its output shaft to rotate the tray body 17 half a turn, moving the lower mold 19 containing the blank workpiece to below the external punch press. The operator then activates the electric push rod 13, causing its output shaft to lower the U-shaped frame 14 and the clamping block 15 into the slot 18. Simultaneously, a workpiece is placed inside another lower mold 19. The operator then activates the punch press, causing the upper mold and lower mold 19 to fit together, extruding the blank workpiece for forming. Once the processing is complete...

[0038] Third, the operator can turn on the servo motor 16 again, so that the output shaft of the servo motor 16 drives the material tray body 17 to rotate half a turn. Then the operator can take out the workpiece. At the same time, when the material tray body 17 moves the lower mold 19, the air nozzle 24 will blow air onto the lower mold 19. Then the operator can repeat the above steps to process.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
