Description

Technical Field

[0001] The invention relates to the technical field of coil edge trimming, in particular to a coil edge trimming mechanism based on an edge trimming process of a tensioning and leveling machine. Background Art

[0002] In the processing flow of metal coils, from the transportation of raw materials to the preliminary processing, the conveying and lifting of coils are indispensable steps. However, in this process, due to the operating accuracy limitations of the handling equipment and the weight and shape characteristics of the coils themselves, the edges of the metal coils are easily damaged by collisions. These damages not only manifest as curling and deformation of the edges, but may also result in the loss of some materials, seriously affecting the quality of the coils and the feasibility of subsequent processing. In order to ensure that the metal coils can achieve the required dimensional accuracy and edge quality standards when entering the subsequent precision processing process, cutting and trimming the damaged edges becomes a necessary preprocessing step.

[0003] In the traditional processing technology, although the cutting equipment can be used to cut the curled or missing parts on both sides of the coil, the stress inside the metal will cause the cut coil part and the cut edge waste to be intertwined. This phenomenon is due to the uneven release of metal stress at the moment of cutting, which leads to the formation of complex interaction forces between the coil body and the waste, causing the two to be tightly entangled; However, the current processing equipment and processes lack an effective solution specifically for this problem, that is, there is a lack of a mechanism that can accurately guide the edges of the waste and wind them in an orderly manner. In the high-precision CNC cutting process, the presence of waste may interfere with the trajectory of the laser or plasma cutting head, resulting in increased roughness of the cutting surface and decreased dimensional accuracy. These problems seriously restrict the overall efficiency and product quality of metal coil processing. Summary of the invention

One end of the upper push rod 601 and the lower push rod 602 are fixedly connected with a pressure block 5 through a short rod. The upper push rod 601 and the lower push rod 602 are slidably connected with the guide rod 7 through two guide grooves opened at the end. The top of the upper push rod 601 and the bottom of the lower push rod 602 are fixedly connected with a support 4. The support 4 is fixedly connected with a cylindrical slider 3 through a through groove on the side wall. An upper track 121 and a lower track 122 are respectively arranged at the top of the upper push rod 601 and the bottom of the lower push rod 602. The upper track 121 and the lower track 122 are both composed of a track 1 and a track 2, and the upper track 121 and the lower track 122 are arranged in mirror symmetry. The inner side walls of the track 1 and the track 2 are respectively provided with a chute 1 and a chute 2, and the chute 1 and the chute 2 are connected end to end, and the cylindrical slider 3 is slidably connected in the chute 1 and the chute 2; The shape of the upper rail 121 is as follows Figure 4 As shown, the slide groove 1 and the slide groove 2 on the inner wall of the upper track 121 are opened correspondingly according to the outer shape of the upper track 121, the track 1 of the upper track 121 is located above the corresponding track 2, and the track 1 of the lower track 122 is located below the corresponding track 2, and the track 2 is a straight track; Embodiment 2: A plurality of front brackets and rear brackets are fixedly installed on the top of the machine base 1, the rear bracket is close to the position of the electric winding roller 18, and a top partition 2 is fixedly installed through the top of the front bracket and the rear bracket, and a straightening machine 20 is arranged inside the front bracket and the rear bracket.

An upper pressing roller 17 is arranged on the top of the lifting plate through a plurality of mounting frames. A lower pressing roller is arranged on the top of the machine base 1 and between the two supporting plates 10 through a plurality of mounting frames. The electric push rod 16 drives the upper pressing roller 17 to descend through the lifting plate, and cooperates with the lower pressing roller to realize pressing and conveying the top and bottom of the coil; Laser cutters 19 for cutting the edges of the coils are fixedly installed on both sides of the bottom of the top partition 2, and an electric winding roller 18 is provided on the top of the machine base 1 near the pallet 10. It should be explained here that the laser cutter 19 and the electric winding roller 18 are existing equipment. The laser cutter 19 is used to laser cut the curled parts of the edges of the coils during transportation, and the electric winding roller 18 is used to wind the cut curled coils.

[0019] Combining the first and second embodiments, it can be seen that the working principle of the present invention is as follows: One end of the metal coil is conveyed to between the upper clamping roller 17 and the lower clamping roller through the tensioning and straightening machine 20. The upper clamping roller 17 and the lower clamping roller respectively assist in clamping and conveying the top and bottom of the coil. At the same time, the chain plate 8 drives the connecting frame 13 arranged at equal intervals to continuously convey. During the synchronous movement, the connecting frame 13 drives the upper ejector rod 601 and the lower ejector rod 602 to move synchronously in the upper track 121 and the lower track 122 respectively through the guide rod 7. The upper ejector rod 601 and the lower ejector rod 602 respectively drive the cylindrical slider 3 to slide in the correspondingly arranged track 1 and track 2 through the correspondingly connected support 4; When the cylindrical slider 3 correspondingly arranged on the outer side of the upper push rod 601 and the lower push rod 602 slides from the track 1 to the track 2, the upper push rod 601 and the lower push rod 602 move along the guide rod 7 and approach each other, further driving the two correspondingly connected pressing blocks 5 to approach each other, and the two pressing blocks 5 approach each other and synchronously clamp the top and bottom of the edge of the coil processed by the straightening machine 20 for the first time, and the edge of the coil is transported in real time under the action of the track 2 and the cylindrical slider 3; When passing under the laser cutter 19, the laser cutter 19 accurately cuts the edge of the coil, and the cut finished coil enters the tensioning and straightening machine 20 in the rear bracket for further processing, while the cut coil edge waste is still held tightly by the pressing block 5 and continues to be conveyed. When the cylindrical slider 3 corresponding to the outer side of the upper push rod 601 and the lower push rod 602 slides from track two to track one and is about to pass the bend of track one, the upper push rod 601 and the lower push rod 602 drive the coil edge waste to gradually separate from the edge of the finished coil, and guide it to the electric winding roller 18 for winding.

[0020] The present invention is a chain plate 8 arranged on both sides of the metal coil, which is closely matched with the connecting frame 13, the upper rail 121 and the lower rail 122 to form a stable and efficient waste processing device. The upper push rod 601 and the lower push rod 602 are precisely directional moved in the upper rail 121 and the lower rail 122 by means of the cylindrical slider 3. This movement mode ensures that the pressure blocks 5 connected at their ends can quickly and accurately move towards or away from each other. In the critical process of cutting the edge of the coil, the pressing blocks 5 on both sides timely and effectively implement real-time clamping operations on the edge waste, avoiding the problem of the waste and the finished coil being interlaced due to metal stress or elastic force from the source. Through this stable clamping force, the waste is firmly fixed on the predetermined conveying path, ensuring that it can move forward in an orderly manner along the channel constructed by the chain plate 8 and the connecting frame 13, without causing any interference to the quality and processing accuracy of the finished coil; After the waste is cut, under the synergistic effect of the above-mentioned structure, it can be accurately guided to the electric winding roller 18 for efficient winding, which not only facilitates the subsequent centralized processing of the waste, but also further improves the cleanliness and safety of the entire processing area, fundamentally solves a series of problems caused by improper waste handling in traditional processing, greatly improves the accuracy and efficiency of metal coil processing, and reduces the defective rate of products caused by waste residue.
