[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1 to 11 The low-smoke halogen-free wire groove punching processing equipment shown includes a frame 1, on which a conveying device 2, a side stamping die 3, and a bottom stamping die 4 are provided. The conveying device 2 is used to convey the processed products, the side stamping die 3 is used to stamp the products horizontally, and the bottom stamping die 4 is used to stamp the products vertically.

[0032] In this embodiment, the frame 1 includes a mounting platform 11 on which a conveying device 2, a side stamping die 3, and a bottom stamping die 4 are mounted. The conveying device 2 includes a front traction conveying mechanism 21 and a rear traction conveying mechanism 22, which are located at opposite ends of the mounting platform 11 of the frame 1, forming a parallel conveying path for the processed product. The side stamping die 3 can be one or more. Specifically, when there are two or more side stamping dies 3, they are staggered and distributed on one or both sides of the conveying path between the front traction conveying mechanism 21 and the rear traction conveying mechanism 22, and are used to process through holes on one or both sides of the product (low-smoke halogen-free cable tray), that is, the side stamping die 3 distributed on one side of the conveying path stamps the through hole corresponding to the side of the processed product. The side stamping die 3 includes a hydraulic cylinder 31, a die base 32, a punch 33, and a die 34. An elastic side pressing mechanism 35 is provided between the punch 33 and the die 34, and a lower pressing mechanism 5 is provided above the die 34. The elastic side pressing mechanism 35 is elastically telescopically installed on one side of the punch 33. When the hydraulic cylinder 31 pushes the punch 33 and the die 34 to cooperate in stamping the product, the elastic side pressing mechanism 35 first presses the product, and at the same time, the lower pressing mechanism 5 presses the product and fixes it on the die 34.

[0033] In this embodiment, the mold base 32 includes a base 321, a first fixed plate 322, a movable plate 323, and a second fixed plate 324. The first fixed plate 322, the movable plate 323, and the second fixed plate 324 are sequentially installed on the base 321 and are mutually positioned and connected by multiple guide posts 325. The hydraulic cylinder 31 is fixedly installed on the first fixed plate 322, and its telescopic rod passes through a through hole provided in the first fixed plate 322 and connects with the movable plate 323. The punch 33 is installed on the movable plate 323, and the die 34 is fixedly installed on the front side of the lower position of the second fixed plate 324. The second fixed plate 324 is provided with a clearance hole 3241, which is a square hole. The hydraulic cylinder 31 pushes the movable plate 323 to drive the punch 33 and the elastic side pressure mechanism 35 to pass through the clearance hole 3241 and cooperate with the die 34 to process (punch through hole) the product.

[0034] The punch 33 includes a base plate 331 and one or more punch pins 332 on the base plate 331. The punch pins 332 are fixed to the movable plate 323 by the base plate 331. The die 34 is a fixed block with punching holes 341, the shape, size and number of which correspond to the shape of the punch pins 332. The base plate 331 of the punch 33 has two or more upper guide posts 333 at its high position and two or more lower guide posts 334 at its low position.

[0035] The elastic side-pressing mechanism 35 is slidably mounted on the upper guide post 333 and lower guide post 334 of the base plate 331, and correspondingly limits its engagement with the punch 33, as shown in the figure. The elastic side-pressing mechanism 35 is mounted on the upper guide post 333 and lower guide post 334, allowing it to move back and forth between them. When the die 34 is fixedly mounted on the base 321, it maintains a certain distance from one side of the fixed plate 324 and is positioned corresponding to the punch stroke of the punch 33 in conjunction with the lower guide post 334 of the base plate 331, as shown in the figure. The bottom of the die 34 is fixed to the base 321. The die 34 has a through hole that mates with the lower guide post 334, restricting the relative movement of the punch 33, the elastic side-pressing mechanism 35, and the die 34 to the same straight line position. This better ensures the precision of product processing. Specifically, the punch 334, the elastic side-pressing mechanism 35, and the die 34 cooperate with each other through multiple lower guide posts 334, ensuring that their working movements are restricted to a straight line. The elastic side-pressing mechanism 35 also cooperates with the upper guide post 333, ensuring that the elastic side-pressing mechanism 35 receives uniform force and moves more smoothly when pushed by the hydraulic cylinder 31. The length of the upper guide post 333 is less than that of the lower guide post 334, ensuring that after the punch 33, the elastic side-pressing mechanism 35, and the die 34 are installed, a low-smoke halogen-free feed channel is maintained between the punch 33 and the die 34.

[0036] The elastic side-pressing mechanism 35 is a movable pressure plate mounted on the base plate 331. This movable pressure plate is square and smaller than the clearance hole 3241. It has a through hole 3111 through which the punch needle 332 of the punch 33 passes. The thickness of the movable pressure plate is less than the length of the punch needle 332 on the punch 33, allowing the punch needle 332 to pass through the movable pressure plate into the die 34. A compression spring 3112 is provided between the movable pressure plate and the base plate 331 of the punch 33, allowing the movable pressure plate to elastically extend and retract on the base plate 331 of the punch 33. The base plate 331 is provided with multiple positioning blind holes 335. The compression spring 3112 is installed between the base plate 331 and the movable pressure plate (elastic side pressing mechanism 35) through the positioning blind holes 335. When in use, the elastic side pressing mechanism 35 passes through the clearance hole 3241 under the push of the hydraulic cylinder 31, and presses the processed product onto the die 34 through the compression spring 3112. Then the hydraulic cylinder 31 continues to push the punch 33 to the die 34 to process the product, so as to avoid the processed product from shifting when stamping on the die 34, thereby improving the quality of the stamped product.

[0037] The through hole 3111 on the elastic side pressure mechanism 35 corresponds to the shape, size and number of the punching pins 332 on the punch 33.

[0038] The pressing mechanism 5 consists of an adjusting plate 51 and two or more pressure rollers 52 on the adjusting plate 51. The pressing mechanism 5 is mounted on the fixed plate 324 via the adjusting plate 51. Specifically, the adjusting plate 51 is formed by bending and pressing two sides of a flat plate at 90° in opposite directions, as shown in the figure. One side (upper part) of the adjusting plate 51 is bent upward at 90°, and the other side (lower part) is bent downward at 90°, so that the adjusting plate 51 forms an adjusting and fixing part 511, a connecting part 512, and a pressing part 513. The adjusting and fixing part 51 is provided with an adjusting slot 514. The adjusting plate 51 is mounted on the fixed plate 324 via screws through the adjusting slot 514 of the adjusting and fixing part 511, so that the adjusting plate 51 forms an up-and-down adjusting structure. The pressure rollers 52 are installed at the position of the pressing part 513 to form a downward pressing state. The pressure rollers are rubber rollers.

[0039] To facilitate adjustment of the working position of the side stamping die 3, two parallel transverse sliding rails 3211 are provided above the base 321, and two parallel longitudinal sliding grooves 3212 are provided below the base 321. A scale 12 is provided on the mounting platform 11 of the frame 1 at the corresponding positions of the transverse sliding rails 3211 and the longitudinal sliding grooves 3212. The lower parts of the first fixing plate 322, the second fixing plate 324, and the die 34 are respectively provided with transverse interfaces 6 that correspond to and cooperate with the transverse sliding rails 3211. The mounting platform 11 of the bracket 1 is provided with... The longitudinal guide rail 7 corresponding to the sliding groove 3212 allows the fixing plate 322, fixing plate 324 and die 34 to be adjusted (movably) mounted on the transverse sliding rail 3211 on the base 321 through the transverse interface 6, forming a transverse movement adjustment function. The required transverse position can be adjusted by the scale 12. At the same time, the longitudinal guide rail 7 on the bracket 1 is adjusted by the longitudinal sliding groove 3212 of the base 321, forming a longitudinal movement adjustment function. The required longitudinal position can be adjusted by the scale 12.

[0040] The outer side of the stamping hole 341 is provided with a sliding guide groove 342, which is used to smoothly discharge the stamped waste material.

[0041] The upper part of the die 34 is provided with a detachable lifting guide protrusion 343. When punching through holes, the lifting guide protrusion 343 increases the force-bearing area between the low smoke halogen-free wire groove and the die, or at the same time increases the contact area of ​​the pressing mechanism, thereby better avoiding large vibrations in the product during processing and improving the processing quality of the product.
