Description

Technical Field

[0001] This invention belongs to the field of sealing strip punching technology, and specifically relates to an automated punching equipment for sealing strip products and its working method. Background Technology

[0002] Previously, the punching stations of the equipment were arranged in a double-sided, double-cavity configuration, with each station equidistant from the others. However, due to the gaps between each station, the equipment became very long and occupied a large area, which was not conducive to site layout and resulted in low space utilization.

[0003] Meanwhile, the previous double-sided, double-cavity punching fixtures required different punching angles for each product, each of which was equipped with a separate cylinder or hydraulic cylinder as the punching power, resulting in higher manufacturing costs. Therefore, the existing punching equipment still needs to be improved. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the above shortcomings, the purpose of this invention is to provide an automated punching equipment for sealing strip products. By improving the structure of the punching equipment, its structural design is made more reasonable. It adopts a single-sided single-cavity form for compact distribution and combines multiple punching stations into one station. Furthermore, the hydraulic cylinder is centrally configured at the punching station as the punching power. This not only reduces the size of the equipment and improves the space utilization rate, but also saves the punching power source on the subsequent punching tooling, thus reducing manufacturing costs.

[0005] Technical Solution: To achieve the above objectives, this invention provides an automated punching and cutting device for sealing strip products, comprising:

[0026] As can be seen from the above technical solution, the present invention has the following beneficial effects:

[0027] 1. The automated punching equipment for sealing strips described in this invention improves the structure of the punching equipment, making its design more rational. It adopts a single-sided, single-cavity configuration for compact arrangement and combines multiple punching stations into one. Furthermore, a centralized hydraulic cylinder is placed at this station to provide the punching power. This reduces the size of the equipment, improves space utilization, and saves on the power source for subsequent punching fixtures, thus lowering manufacturing costs. Simultaneously, a servo-driven rotary carriage is used to rotate the sealing strip to the required entry angle, overcoming the directional limitations of the punching power caused by the centralized hydraulic cylinder, thereby improving the stability and convenience of product punching.

[0028] 2. The strip loading trolley adopts a single-sided placement form. The strip loading module of the trolley is driven to rotate to any angle by the strip pressing rotation drive mechanism of the trolley. This overcomes the limitation of the punching direction caused by the centralized configuration of the hydraulic cylinder of the single-sided multi-cavity tooling, and effectively improves the stability and convenience during the punching process.

[0029] 3. The mutual cooperation between the cross-section of the lower track wall plate and the cross-section of the upper track wall plate, as well as the mutual cooperation between the cross-section of the mounting bar semi-circular gear and the cross-section of the pressure bar semi-circular gear, enables the trolley to self-position and lock, effectively ensuring the normal operation of the trolley and improving its operational stability. At the same time, it can reduce the number of trolley positioning devices on the equipment, thereby reducing the manufacturing cost of the equipment.

[0030] 4. The setting of the reference positioning component and the reference position limiting block can improve the position of the ball head positioning post in the reference positioning component on the concave surface of the reference position limiting block, thereby restricting the rotation of the lower half of the semi-circular gear rotating component. This allows the trolley pressure bar rotating drive part to smoothly descend and dock with the trolley when the trolley rotating transport part moves to the last standby position.

[0031] 5. In this invention, the integrated punching device adopts a compact arrangement of single-sided single cavities to combine multiple punching fixtures into one integrated fixture. With the integrated punching power on the equipment, the punching power source required for the fixture is reduced. In addition, by integrating them into a frame, the need for repetitive frame parts caused by multiple punching fixtures is reduced, thereby reducing the overall manufacturing cost of the punching fixture.

[0032] 6. The front positioning block and the rear clamping block can further improve the stability of the single-cavity tooling installation and prevent it from shifting during use. Attached Figure Description

[0076] The working method of the automated punching equipment for sealing strip products described in this embodiment is as follows: 1): The product is mounted on the sealing strip sheet metal 31171 under the positioning guidance of the sealing strip positioning module 5;

[0077] 2): The conveyor drive assembly 25 drives the timing belt main pulley 22 to rotate. During operation, the timing belt main pulley 22 will rotate through the timing belt 24 and the timing belt driven pulley 23.

[0078] 3): The trolley rotary conveyor 311 is driven by the synchronous belt 24 to the punching standby position. At the same time, during the movement, the trolley rotary conveyor 311 is guided by the cooperation of the annular inclined guide rail 27 and the inclined guide wheel 3116, and the offset gap in the left and right directions is eliminated, which lays a good foundation for the subsequent fitting and cooperation with the trolley pressing strip rotary drive mechanism 312.

[0079] 4): The lifting drive mechanism 32 drives the trolley pressing strip rotation drive mechanism 312 to descend. The third groove 31211 on the upper track wall plate 3121 and the second positioning protrusion 31241 on the pressing strip semicircular gear 3124 in the trolley pressing strip rotation drive mechanism 312 engage with each other. At this time, the strip loading trolley is in a locked state. The upper and lower semicircular tracks of the upper and lower parts, as well as the pressing strip semicircular gear 3124 and the strip loading semicircular gear 3114, are combined into one. The pressing strip assembly 3125 presses the sealing strip tightly onto the strip loading sheet metal 31171. At the same time, under the downward pressing engagement of the trolley pressing strip rotation drive mechanism 312, the trolley rotation conveying mechanism 311 is limited and locked in the front, back, left and right directions.

[0080] 5): The rotary drive motor 31261 of the trolley pressing strip rotary drive mechanism 312 drives the power gear 31262 to rotate. The power gear 31262 drives the gear rotating assembly of the pressing strip semicircular gear 3124 and the mounting strip semicircular gear 3114 to rotate along the track that combines the upper and lower semicircular tracks, and stops after rotating the product to the required angle.

[0081] 6): The integrated punching device 4 moves forward to punch the product. After punching, the integrated punching station 4 moves backward. That is, the punching plate 471 moves downward under the drive of the punching drive mechanism 472 and collides with the force block 434 of the single-sided multi-cavity punching fixture. The force block 434 is driven by the force to punch the punching component 433 until the upper power limit reference block 473 mounted on the punching plate 471 and the lower power limit block 412 on the single-sided multi-cavity punching fixture are pressed together. At this time, the punching plate 471 stops moving downward. At this time, the punching of the sealing strip is completed. Then the punching plate 471 moves upward under the drive of the punching drive mechanism 472.

[0082] 7): The rotary drive motor 31261 of the trolley strip pressing rotary drive mechanism 312 drives the rotating part of the rotary strip loading trolley 3 to rotate back to the initial state.
