Description

Technical Field

[0001] This utility model relates to the technical field of shoe production equipment, and in particular to the technical field of punching machines for shoe production. Background Technology

[0002] In shoe manufacturing, punching is a common process for both shoelace holes and ventilation holes. As consumer demands become increasingly diverse, different hole shapes (such as round, square, triangular, and irregular shapes) are required to meet these needs. Traditional punching equipment faces several technical bottlenecks when dealing with multi-shape punching requirements, including low die-changing efficiency: Existing equipment often uses a fixed combination of punches and punches. Changing the punch shape requires stopping the machine to disassemble the old punch, install a new punch, and recalibrate, a time-consuming process that severely impacts production continuity, making it particularly unsuitable for flexible production scenarios with small batches and diverse product varieties. Furthermore, for materials requiring multiple sets of punches (such as continuously arranged holes), traditional equipment struggles to achieve synchronous switching and coordinated punching of multiple sets of punches, easily leading to inconsistent hole shapes and spacing deviations, thus reducing the production yield. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a punching machine for shoe production, which solves the problems of inconvenient cross-sectional shape switching and low efficiency of traditional shoe punching equipment.

[0004] To achieve the above objectives, this utility model proposes a punching machine for footwear production, including a feeding guide mechanism, a punching power mechanism, a multi-shape switchable punching actuator, and a worktable. The worktable is provided with a feeding guide mechanism for conveying materials. The side of the feeding guide mechanism is provided with a row of interconnected multi-shape switchable punching actuators for punching materials and with switchable punches. The worktable on the side of the multi-shape switchable punching actuator is provided with a punching power mechanism for driving the multi-shape switchable punching actuator to rise and fall.

[0005] Preferably, the feeding guide mechanism includes a feeding guide frame, a feeding motor, a feeding roller, and a synchronous pulley. The feeding guide frame has a feeding roller that cooperates with the worktable to transport materials on the side facing the multi-shape switchable stamping actuator. The feeding guide frame is equipped with a feeding motor. The rotating shaft of the feeding motor and the rotating shaft of the feeding roller are respectively equipped with synchronous pulleys. The synchronous pulleys are connected by a synchronous belt.

[0006] Preferably, the lower rear end of the feeding guide frame is fixed to the worktable.

The stamping hydraulic cylinder is vertically fixed on the worktable. The stamping seat is fixed on the telescopic shaft of the stamping hydraulic cylinder. The stamping push rod is fixed on the lower side of the stamping seat. The lower end of the stamping push rod is provided with a thrust bearing.

[0008] Preferably, a stamping guide shaft is vertically fixed on the worktable, and the upper end of the stamping guide shaft passes through the stamping seat.

[0009] Preferably, the multi-shape switchable stamping actuator includes a lifting stamping seat, a stamping base, a stamping guide synchronous shaft, a return spring, and a punch switching motor. The upper end of the stamping guide synchronous shaft is fixed to the lifting stamping seat, and the lower end of the stamping guide synchronous shaft passes through the stamping base. A return spring is sleeved on the stamping guide synchronous shaft between the lifting stamping seat and the stamping base.

Detailed Implementation

[0023] See Figure 1 and Figure 2 This utility model relates to a punching machine for footwear production, comprising a worktable 1, a feeding guide mechanism 2, a multi-shape switchable punching actuator 4, and a punching power mechanism 3. The worktable 1 serves as the mounting base for the entire equipment, placed horizontally on the ground, and supports the feeding guide mechanism 2, the punching power mechanism 3, and the multi-shape switchable punching actuator 4. The feeding guide mechanism 2 is mounted on the worktable 1 and is used to transport the material to be processed into and out of the equipment, ensuring the stability of the material's position during the punching process. The multi-shape switchable punching actuator 4 is located on the side of the feeding guide mechanism 2, arranged in a row and interconnected, and can achieve punching processing of different shapes by switching punches. The punching power mechanism 3 is mounted on the worktable 1 on the side of the multi-shape switchable punching actuator 4 and is used to drive the multi-shape switchable punching actuator 4 to rise and fall, providing the power required for punching.

[0024] Specifically, as shown in Figure 3, the feeding guide mechanism 2 includes a feeding guide frame 21, a feeding motor 22, a feeding roller 23, and a synchronous pulley 24. The lower rear end of the feeding guide frame 21 is fixed on the worktable 1, and a gap is formed between the front end and the worktable 1 for material to pass through. The feeding roller 23 is installed on the side of the feeding guide frame 21 facing the multi-shape switchable stamping actuator 4. The feeding motor 22 is fixed on the feeding guide frame 21, and synchronous pulleys 24 are respectively installed on its rotation shaft and the rotation shaft of the feeding roller 23. The two synchronous pulleys 24 are connected by a synchronous belt drive. After the feeding motor 22 starts, it drives the feeding roller 23 to rotate through the synchronous pulleys 24 and the synchronous belt. The feeding roller 23 presses the material onto the surface of the worktable 1. With the rotation of the feeding roller 23, the material is input (entering the stamping area) and output (leaving the stamping area). The conveying speed can be adjusted according to the processing requirements.

[0025] It should be noted that, as shown in Figure 4, the stamping power mechanism 3 includes a stamping hydraulic cylinder 31, a stamping seat 32, a stamping guide shaft 33, a stamping push rod 34, and a thrust bearing 35. The stamping hydraulic cylinder 31 is vertically fixed on the worktable 1, and its telescopic shaft is fixedly connected to the stamping seat 32 at its top end; the worktable 1 is also vertically fixed with the stamping guide shaft 33, the upper end of which passes through the stamping seat 32 and is slidably connected to it; the stamping push rod 34 is fixed on the lower side of the stamping seat 32, and the lower end of the stamping push rod 34 is equipped with a thrust bearing 35. When the telescopic shaft of the stamping hydraulic cylinder 31 extends, it drives the stamping seat 32 to move downward along the stamping guide shaft 33. The stamping push rod 34 presses against the multi-shape switchable stamping actuator 4 through the thrust bearing 35, providing the pressure required for punching. After stamping is completed, the telescopic shaft of the stamping hydraulic cylinder 31 retracts, driving the stamping seat 32 and the stamping push rod 34 to reset. The thrust bearing 35 ensures that the stamping push rod 34 does not affect the rotation of the multi-shape switchable stamping actuator 4 during the driving process.

[0026] It is understandable that, such as Figure 5As shown in Figure 7, the multi-shape switchable stamping actuator 4 includes a lifting stamping seat 41, a stamping base 42, a stamping guide synchronous shaft 43, a return spring 44, and a punch switching motor 45. The stamping base 42 is fixed on the worktable 1, and multiple punch holes 421 are opened around it (corresponding to punches of different shapes, such as round, square, and triangular). The lifting stamping seat 41 is located above the stamping base 42, and punches 411 corresponding to the number and position of punch holes 421 are arranged around it. The upper end of the stamping guide synchronous shaft 43 is fixed to the lifting stamping seat 41, and the lower end passes through the stamping base 42 and is slidably connected to it. The return spring 44 is sleeved on the stamping guide synchronous shaft 43 between the lifting stamping seat 41 and the stamping base 42. The rotating shaft of the punch switching motor 45 is connected to the rotating shaft of the stamping base 42, and adjacent stamping bases 42 mesh with each other through the surrounding synchronous teeth. When it is necessary to change the punch shape, the punch switching motor 45 starts, driving all the stamping bases 42 to rotate synchronously through the synchronous gear. At the same time, the lifting stamping base 41 rotates synchronously with the stamping base 42 (the thrust bearing 35 can adapt to the rotation requirements), so that the punch 411 of the target shape is aligned with the punch 421 of the material. When the stamping power mechanism 3 drives the lifting stamping base 41 to descend, the punch 411 passes through the material and inserts into the corresponding punch 421, completing the punching. After the stamping power mechanism 3 resets, the return spring 44 pushes the lifting stamping base 41 to rise to the initial position, waiting for the next stamping.

[0027] The working process of this utility model:

[0028] During operation, the punching machine for shoe production of this utility model is as follows: the material to be processed is fed through the gap between the feeding guide frame 21 and the worktable 1. The feeding motor 22 drives the feeding roller 23 to rotate, conveying the material to the punching position below the multi-shape switchable punching actuator 4. After the material arrives, the feeding motor 22 stops. According to the required hole shape, the punch switching motor 45 is started, which drives all the punching bases 42 and the lifting punching base 41 to rotate synchronously through the synchronous gear, so that the punches 411 and punch holes 421 of the corresponding shapes are aligned with the punching position of the material. The telescopic shaft of the punching hydraulic cylinder 31 extends, driving the punching base 32 and the punching top rod 34 to descend. The thrust bearing 35 presses the lifting punching base 41, causing the punch 411 to descend and pass through the material, completing the punching; at this time, the return spring 44 is compressed. The telescopic shaft of the stamping hydraulic cylinder 31 retracts, the stamping seat 32 and the stamping top rod 34 rise and reset, the reset spring 44 pushes the lifting stamping seat 41 to rise, and the punch 411 disengages from the material; the feeding motor 22 starts again and conveys the material to the next punching position (or sends it out of the equipment), and repeats the above steps to complete the subsequent punching.

[0029] This invention enables rapid switching between multiple punch shapes without stopping the machine to change molds. Furthermore, through the coordinated operation of the feeding guide mechanism 2 and the stamping mechanism, it ensures processing accuracy and efficiency, making it suitable for flexible production scenarios with small batches and multiple varieties.

[0030] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
