Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and in particular to an automatic stamping device. Background Art

[0002] In the field of metal processing, stamping is a commonly used processing method, in which metal sheets such as steel strips are stamped and formed by a stamping die to obtain a workpiece of the desired shape.

[0003] At present, for the stamping processing of steel strips, manual feeding is still used in many cases. That is, the worker manually feeds the steel strip into the stamping die a certain distance, starts the stamping equipment for stamping, and then manually feeds it a distance for the next stamping after the stamping is completed. However, this manual operation method has many disadvantages: on the one hand, the accuracy of manual feeding is difficult to guarantee, which can easily lead to deviations in the size of the stamped parts and affect product quality; on the other hand, the width of the steel strip does not necessarily match the size of the stamped parts. In order to save materials, it is usually necessary to use a staggered method for stamping. However, it is difficult to accurately control the position and distance of the staggered operation by manual operation, which easily generates a lot of waste and increases production costs. In addition, manual operation next to the stamping equipment poses a great safety hazard. Workers may suffer work-related accidents if they are not careful. In addition, the efficiency of manual operation is low and cannot meet the needs of large-scale production.

[0004] In order to solve the above problems, the present invention proposes an automatic stamping device that can realize automatic feeding, accurately control staggered stamping, improve production efficiency and ensure production safety. Summary of the Invention

[0005] In order to solve the technical problems existing in the background technology, the present invention proposes an automatic punching device.

[0006] An automatic stamping device proposed by the present invention includes a stamping machine body, platforms are symmetrically provided on both sides of the stamping machine body, two groups of the platforms are slidably connected to a sliding table, and the two groups of the sliding tables are fixedly connected to vertical plates. Each group of the vertical plates is provided with a pair of conveyor belts distributed in parallel up and down. The two pairs of conveyor belts can clamp the material belt and convey it between the upper die and the lower die of the stamping machine body. The vertical plates are equipped with a spacing adjustment mechanism, and the spacing adjustment mechanism is used to adjust the clamping gap between the two groups of conveyor belts. The conveying direction of the conveyor belt is perpendicular to the sliding direction of the sliding table.

[0007] A feeding mechanism is installed on the punching machine body, and a connecting frame is connected between the two groups of vertical plates. The feeding mechanism drives the two groups of sliding tables to slide synchronously along the platform through the connecting frame;

[0008] A discharge conveyor is provided on the front side of the stamping machine body, and the conveying direction of the discharge conveyor is parallel to the conveying direction of the material belt. A slide is installed on the stamping machine body, and the discharge end of the slide guides the discharge conveyor. A telescopic rod is installed on the stamping machine body, and a push plate is installed on the output end of the telescopic rod. The push plate is used to push the stamped workpiece onto the slide and slide it to the discharge conveyor via the slide.

[0009] Preferably, a plurality of groups of conveying rollers are rotatably mounted on the slide, and the plurality of groups of conveying rollers are spaced apart along the length direction of the slide.

[0010] Preferably, an L-shaped baffle is fixed to the side wall of the slide, and the horizontal section of the L-shaped baffle extends to above the discharge conveyor belt.

[0011] Preferably, a buffer layer is provided on the inner wall of the L-shaped baffle, and the buffer layer is made of elastic material.

[0012] Preferably, the spacing adjustment mechanism includes a guide column vertically fixed on the vertical plate, and a lifting seat is slidably sleeved on the guide column; the upper conveyor belt is installed on the lifting seat, and the lower conveyor belt is fixedly installed on the vertical plate and is located directly below the lifting seat; an adjusting bolt is also rotatably installed on the vertical plate, the axis of the adjusting bolt is parallel to the guide column, and the lower end of the adjusting bolt is threadedly connected to the lifting seat, and a driving member is also installed on the vertical plate, and the upper end of the adjusting bolt is connected to the transmission shaft of the driving member.

[0013] Preferably, the feeding mechanism includes a servo motor mounted on the punching machine body, a lead screw connected to the output end of the servo motor, and a nut seat threadedly connected to the lead screw, and the nut seat is fixedly connected to the connecting frame.

[0014] Preferably, a linear guide rail is installed on the platform, and a slider adapted to the linear guide rail is provided at the bottom of the sliding platform, and the slider is slidably connected to the linear guide rail.

[0015] Preferably, the conveyor belt is provided with an anti-slip rubber sleeve, and the outer surface of the anti-slip rubber sleeve is provided with anti-slip lines.

[0016] In the present invention, an automatic stamping device is proposed, which transports the steel belt by clamping the upper and lower conveyor belts on the vertical plates on both sides, and cooperates with the feeding mechanism to drive the sliding table to move horizontally, replacing the traditional manual feeding operation. There is no need for workers to be on duty at the discharge conveyor belt position, fundamentally eliminating the risk of work-related injuries that may be caused by manual operation, and significantly improving production safety.

[0017] The feeding mechanism can drive the sliding table to move horizontally, thereby adjusting the lateral position of the material strip. Combined with the longitudinal conveying of the conveyor belt, it can accurately control the stamping position of the steel strip, realize the staggered stamping mode, effectively reduce waste generation, improve the utilization rate of the steel strip, and reduce production costs.

[0018] The upper and lower conveyor belts clamp the steel belt from both sides, which can form a stable positioning of the steel belt during transportation, avoiding position deviation during manual feeding, ensuring the dimensional accuracy and consistency of the stamping parts, and improving product quality.

[0019] The automated feeding, stamping and discharging processes form a continuous assembly line operation, avoiding the efficiency fluctuations caused by the discontinuity and fatigue of manual operation, and greatly improving the overall production efficiency.

[0020] The stamped workpiece is pushed onto the slide by the push plate and guided to the discharge conveyor belt by the L-shaped baffle to prevent the workpiece from falling, ensuring a stable and orderly discharge process. Further combined with the conveyor rollers on the slide, the workpiece conveying resistance can be reduced to avoid workpiece jamming.

[0021] The spacing adjustment mechanism can adjust the clamping gap between the two sets of conveyor belts to adapt to material belts of different thicknesses; the feeding mechanism can adjust the feed amount according to stamping parts manufactured by different molds and material belts of different widths, thereby improving the versatility of the device.

[0022] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
