Description

Technical Field

[0001] The utility model relates to a feeding device for punching a cable bridge, belonging to the technical field of punching. Background Art

[0002] Cable trays come in trough, tray, ladder, and grid configurations, and are composed of brackets, supports, and mounting accessories. Trough cable trays are fully enclosed cable trays. They are ideal for laying computer cables, communication cables, thermocouple cables, and other control cables for highly sensitive systems. They effectively shield control cables from interference and protect cables from severe corrosive environments.

[0003] Existing cable trays are generally produced by stamping. Traditional punching machines require manual loading during processing, which increases the labor intensity of workers. At the same time, when manually loading, the workers' hands will be close to the punch, posing a threat to the workers' personal safety and resulting in a low safety factor.

[0004] In response to the above problems, corresponding solutions have emerged in the industry, such as the Chinese authorized utility model patent with the authorization announcement number: CN 221184401U, and the patent name: A punching machine automatic feeding device for the production of cable tray connectors. In the above patent, a turntable can be rotated and the parts to be punched are placed on the discharge block in the turntable. Each time the turntable rotates, the parts to be punched can be vertically aligned with the punch, cylinder, and storage barrel respectively, to achieve punching, unloading, and loading of the parts to be punched, reducing the labor intensity of the staff and ensuring the personal safety of the staff.

[0005] However, the above patent has the following problems during use: 1. In the above patent, the materials to be punched are placed in the storage barrel in order, and the discharge block is driven to rotate by the turntable to send the materials in the storage barrel to the bottom of the punching head for punching. In actual operation, the materials to be punched are generally cut before punching. After cutting, the materials to be punched are placed in the material frame in order, and then the materials in the material frame are placed in the storage barrel, which makes the loading process more cumbersome and reduces the loading efficiency.

[0006] 2. After the material is stamped, the cylinder is started to knock the stamped parts away. The parts to be stamped can be received by the receiving hopper to complete the unloading. In the above process, the cylinder violently impacts the stamped parts, and the cylinder will deform the bottom of the stamped parts, resulting in scrapped stamped parts. At the same time, when the stamped parts are knocked away and fall into the receiving hopper, the stamped parts in the receiving hopper are placed in a disorderly manner. In order to facilitate the subsequent assembly line production, workers have to manually place them neatly, which is not only time-consuming and labor-intensive, but also increases the labor intensity of workers.

[0028] In order to achieve the purpose of stamping, the upper mold support structure 3 further includes an upper mold support frame 301 with a door-shaped structure, and a lifting cylinder 302 is provided on the inner side of the upper surface of the upper mold support frame 301, and an upper stamping mold 303 is provided at the end of the cylinder shaft of the lifting cylinder 302.

[0029] like Figure 4 As shown, in order to realize flipping and blanking, the lower mold flipping structure 5 further includes a plurality of first flipping motors 501 and second flipping motors 502, and the first flipping motors 501 and the second flipping motors 502 are respectively installed on the ends of the first support plate 1 and the second support plate 2, and a lower mold mounting frame 503 is arranged between the first flipping motor 501 and the second flipping motor 502, and the lower mold mounting frame 503 is respectively connected to the motor shafts of the first flipping motor 501 and the second flipping motor 502, and a lower stamping die 504 is arranged in the lower mold mounting frame 503.

[0030] like Figure 5 and Figure 6 As shown, in order to facilitate the removal of materials, the material placement frame structure 6 further includes an internally hollow material placement frame 601, a bottom insertion hole 602 is provided at the bottom of the material placement frame 601, a bottom support plate 603 is provided in the material placement frame 601, and multiple materials to be stamped 604 are stacked in the material placement frame 601.

[0031] like Figure 7As shown, in order to be able to push the material to be punched out from the material placement frame 601, the material pushing structure 8 further includes a material pushing bracket 801, and an upward pushing cylinder 802 is arranged inside the material pushing bracket 801. The cylinder shaft of the upward pushing cylinder 802 passes through the material pushing bracket 801 and extends to the outside of the material pushing bracket 801.

[0032] In order to push the material into the mold, the feeding structure 9 further includes a feeding cylinder 901 , and a feeding push plate 902 is provided on the cylinder shaft of the feeding cylinder 901 .

[0033] In order to be able to collect materials, a material placement frame 601 is further placed on the bottom support frame 7.

[0034] In order to improve the supporting strength, support rods 701 are further provided between the first support plate 1 and the second support plate 2 and the bottom support frame 7 .

[0035] During use, the cut material to be stamped 604 is placed in the material placement frame 601. In this patent, a bottom support plate 603 is provided at the inner bottom of the material placement frame 601, so that the cut material to be stamped 604 will be stacked on the bottom support plate 603. The material placement frame 601 stacked with the material to be stamped 604 is placed in the material frame placement slot 101 and falls onto the material pushing bracket 801. At this time, the cylinder shaft of the push cylinder 802 will be inserted into the bottom insertion hole 602 and support the bottom support plate 603 in the material placement frame 601.
