Description

Technical Field

[0001] This utility model relates to the field of metal processing and cutting technology, specifically a high-precision CNC manual fixed-length cutting device. Background Technology

[0002] In the processing of metal strip, it is often necessary to cut coiled metal strip into finished products of specific lengths according to actual production needs, which requires the use of fixed-length cutting equipment. Currently, there are many types of fixed-length cutting equipment on the market, among which CNC manual fixed-length cutting equipment is widely used in small and medium batch metal strip processing scenarios due to its relatively flexible operation and moderate cost.

[0003] However, existing high-precision CNC manual length-fixed cutting equipment still has some drawbacks in actual use: On the one hand, the length-fixed adjustment of traditional equipment mostly relies on operators manually adjusting the limit structure based on their experience. This adjustment method lacks a precise positioning reference and is prone to inaccurate limit positions after adjustment due to differences in operator experience or operational errors. This results in inconsistent lengths of the cut metal strips, causing length deviations, which seriously affect product quality, increase the defect rate, and raise production costs. On the other hand, although some equipment is equipped with length-fixed adjustment components, the adjustment process is complex and requires repeated measurement and adjustment with the help of additional measuring tools. This is cumbersome, time-consuming, and reduces production efficiency.

[0004] To address these issues, we designed a high-precision CNC manual fixed-length cutting device. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision CNC manual fixed-length cutting device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-precision CNC manual fixed-length cutting device, including a worktable, an unwinding assembly for unwinding a metal coil on one side of the worktable, a cutting assembly for cutting the metal coil on one side of the top of the worktable, fixing assemblies for moving the metal coil symmetrically arranged on both sides of the worktable, and a fixed-length assembly on the worktable, the fixed-length assembly including an adjusting plate that moves horizontally on the top surface of the worktable and a rotating component for abutting the adjusting plate.

[0007] Furthermore, the fixed-length component also includes two symmetrically formed sliding grooves on the top surface of the worktable. A sliding seat is horizontally slidably arranged in the sliding groove. The sliding seat is elastically connected to the inner sidewall of the sliding groove by a clamping spring. The top surfaces of the two sliding seats are fixedly connected to the bottom surface of the adjusting plate.

[0008] Furthermore, a guide rod is fixedly installed inside the groove, the sliding seat is slidably installed on the outer arc wall of the guide rod, and the clamping spring is sleeved on the guide rod.

[0009] Furthermore, a transmission rod is fixedly installed at the center of the rotating component, and mounting plates are fixedly installed on both sides of the worktable. The two ends of the transmission rod are respectively rotatably installed on the side walls of the two mounting plates.

[0010] Furthermore, the rotating component includes a rotating disk, and the rotating disk has a plurality of abutment rods arranged in a ring along its edge for abutting the adjusting plate, the lengths of the plurality of abutment rods increasing sequentially.

[0011] Furthermore, each of the abutting rods has an abutting part fixedly connected to its end away from the rotating disk, and the adjusting plate has a slot on its side wall near the rotating part that is adapted to the size of the abutting part. The abutting part is shaped like a frustum.

[0012] Furthermore, the rotating disk and the abutment rod are detachably connected by bolts.

[0013] Furthermore, a limiting frame is fixedly connected to the workbench, and an opening for storing finished products is provided on the workbench.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a length-fixing assembly consisting of an adjusting plate, a rotating component, a sliding seat, and a clamping spring is provided. By utilizing the abutment rods of different lengths on the rotating component to engage with the adjusting plate, the position of the adjusting plate can be precisely adjusted. The abutment rods of different lengths correspond to different preset lengths of finished strip materials. This eliminates the need for operators to adjust based on experience, effectively avoiding the problem of inaccurate length-fixing caused by human error. It significantly improves the accuracy of fixed-length cutting of metal strip materials, ensures the uniformity of finished product length, and reduces the defect rate.

[0016] 2. In this utility model, the adjustment operation of the fixed length component is simple and quick. The operator only needs to rotate the rotating disk to switch the abutment rods of different lengths to abut against the adjusting plate, and fix it through the cooperation of the abutment part and the slot to complete the fixed length adjustment. There is no need to use additional measuring tools to repeatedly measure and adjust, which greatly shortens the adjustment time and improves production efficiency. At the same time, the setting of the clamping spring makes the adjusting plate always tend to abut against the rotating part, and the snap-fit ​​cooperation of the abutment part and the slot further ensures the stability of the position of the adjusting plate, effectively preventing the position of the adjusting plate from shifting during the operation of the equipment, and ensuring the stability of the fixed length accuracy.

[0017] 3.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a high-precision CNC manual fixed-length cutting device, including a worktable 1, an unwinding component 2 for unwinding a metal coil is provided on one side of the worktable 1, a cutting component 3 for cutting the metal coil is provided on one side of the top of the worktable 1, fixing components 4 for moving the metal coil are symmetrically arranged on both sides of the worktable 1, and a fixed-length component 5 is provided on the worktable 1. The fixed-length component 5 includes an adjusting plate 6 that moves horizontally on the top surface of the worktable 1 and a rotating component 7 for abutting the adjusting plate 6.

[0025] The fixed-length component 5 also includes two symmetrically opened slide grooves 8 on the top surface of the workbench 1. A sliding seat 9 is horizontally slidably arranged in the slide groove 8. The sliding seat 9 is elastically connected to the inner side wall of the slide groove 8 by a retaining spring 10. The top surfaces of the two sliding seats 9 are fixedly connected to the bottom surface of the adjusting plate 6. A guide rod 11 is fixedly arranged in the slide groove 8. The sliding seat 9 is slidably installed on the outer arc wall of the guide rod 11. The retaining spring 10 is sleeved on the guide rod 11. A transmission rod 13 is fixedly arranged at the center position of the rotating component 7. Mounting plates 12 are fixedly arranged on both sides of the workbench 1. The two ends of the transmission rod 13 are respectively rotatably installed on the side walls of the two mounting plates 12. The rotating component 7 includes a rotating disk 14. Multiple abutting rods 15 for abutting the adjusting plate 6 are arranged in a ring along the edge of the rotating disk 14. The length of the multiple abutting rods 15 increases sequentially. A limit frame 18 is fixedly connected to the workbench 1. An opening 19 for storing finished products is opened on the workbench 1.

[0026] In practice, the metal coil is first placed on the unwinding assembly 2. The unwinding drum of the unwinding assembly 2 rotates, driving the metal coil to unwind stably. Then, the metal strip corresponding to the limiting frame 18 is threaded through the limiting frame 18. The limiting frame 18 plays a limiting and guiding role for the metal strip, preventing the strip from shifting during movement. Next, the metal strip is pulled to the fixing components 4 symmetrically arranged on both sides of the worktable 1. The fixing components 4 firmly clamp both ends of the strip to ensure the stability of the strip's position during subsequent movement and cutting. Then, according to the actual required finished product length, the operator rotates the rotating component 7 installed on the transmission rod 13. The two ends of the transmission rod 13 are rotatably installed on the mounting plate 12 to ensure smooth rotation of the rotating component 7. By rotating the rotating disk 14, different lengths of the abutment rod 15 are switched, so that the frustum-shaped abutment part 16 at the end of the abutment rod 15 of the required length is inserted into the slot 17 of the adjusting plate 6, thereby temporarily fixing the rotating component 7 to the adjusting plate 6.

[0027] During this process, the bottom surface of the adjusting plate 6 is fixedly connected to two sliding seats 9. The sliding seats 9 slide on the guide rod 11 in the slide groove 8. The clamping spring 10 is sleeved on the guide rod 11 and elastically connected to the sliding seat 9. Under the action of the clamping rod 15, the sliding seat 9 moves along the guide rod 11 and stretches the clamping spring 10, driving the adjusting plate 6 to move horizontally to the preset position on the top surface of the workbench 1, thus completing the setting of the fixed length. Then, the fixing component 4 drives the metal strip to move towards the adjusting plate 6. When the end of the metal strip abuts against the side wall of the adjusting plate 6, the fixing component 4 stops moving. At this time, the cutting component 3 is started to precisely cut the metal strip. The cut finished product falls from the opening 19 on the workbench 1 into the storage structure inside the workbench 1, thus completing the collection of finished products. Repeating the above steps can realize continuous high-precision fixed-length cutting of metal strip.

[0028] The unwinding assembly 2 can adopt the existing motor-driven unwinding structure to ensure stable unwinding speed of the metal coil, match the subsequent cutting rhythm, avoid slack or stretching of the strip, ensure the stability of strip feeding, and thus improve cutting accuracy. The unwinding speed of the unwinding assembly 2 can be adjusted by the CNC system to match the moving speed of the fixed assembly 4 and the cutting frequency of the cutting assembly 3, forming a collaborative working mechanism to further improve the automation level and production efficiency of the equipment. At the same time, it prevents the strip from accumulating or breaking due to excessively fast or slow unwinding speed, reducing production failures.

[0029] The cutting component 3 can adopt a CNC hydraulic cutting structure or a CNC pneumatic cutting structure. The CNC system controls the lifting speed and cutting force of the cutting blade to ensure that the cut surface is flat and free of burrs, deformation and other problems, thus meeting the cutting quality requirements of high-precision processing. The clamping surface of the fixing component 4 can be equipped with a rubber anti-slip pad to increase the friction between the fixed component and the metal strip, further preventing the strip from slipping or shifting during movement and cutting. At the same time, the rubber anti-slip pad can prevent excessive clamping force from damaging the surface of the strip and ensure the appearance quality of the finished product.

[0030] See Figure 3 and Figure 4 Each of the multiple abutting rods 15 has an abutting part 16 fixedly connected to one end away from the rotating disk 14. The adjusting plate 6 has a slot 17 on one side wall near the rotating part 7 that is adapted to the size of the abutting part 16. The abutting part 16 is shaped like a frustum. The rotating disk 14 and the abutting rods 15 are detachably connected by bolts.

[0031] In practice, the abutment part 16 adopts a frustum-shaped structure, with its small diameter end facing the adjustment plate 6 and its large diameter end fixedly connected to the abutment rod 15. This structural design facilitates the quick and smooth insertion of the abutment part 16 into the slot 17. At the same time, the large diameter end can prevent the abutment part 16 from being over-inserted into the slot 17, thus playing a limiting role and ensuring the stability of the abutment rod 15 and the adjustment plate 6.

[0032] The surface of the rotating disk 14 can be marked with fixed length scales corresponding to each abutment rod 15. Operators can quickly identify the fixed length of the abutment rod 15 currently in use through the scales without additional measurement, further simplifying the operation steps, improving adjustment efficiency, and reducing adjustment errors. The edge of the rotating disk 14 can be provided with anti-slip texture to increase the friction when the operator rotates the rotating disk 14, making it easier for the operator to apply force, while preventing hand slippage and operation errors, thus improving the safety and convenience of operation.

[0033] Working principle:

[0034] The metal coil is placed on the unwinding assembly 2. The unwinding drum rotates, thereby driving the metal coil on the unwinding drum to unwind. The strip corresponding to the limiting frame 18 is threaded into the limiting frame 18. Then the metal strip is pulled to the fixing assembly 4 and the two ends of the strip are clamped. When the fixing assembly 4 moves to the position of abutting the side wall of the adjusting plate 6, the ends of the strip abut against the adjusting plate 6. Then the cutting assembly 3 is started to cut the metal strip. The cut finished product falls into the worktable 1 from the opening 19 of the worktable 1, completing the collection of the finished product.

[0035] In use, the operator first adjusts the position of the adjusting plate 6 according to actual needs. By adjusting the position of the adjusting plate 6, the metal strip can be cut to a fixed length, so that the cut finished product is of uniform length. Rotating the rotating part 7, the operator switches the abutting rods 15 of different lengths to abut the adjusting plate 6. With the help of the clamping spring 10 set at one end of the sliding seat 9, the adjusting plate 6 slides along the upper surface of the worktable 1, changing the horizontal position of the adjusting plate 6 on the top surface of the worktable 1. When the adjusting plate 6 moves to the appropriate position, the abutting part 16 of the end of the abutting rod 15 of the required length is inserted into the slot 17 to temporarily fix the rotating part 7. Different lengths of abutting rods 15 correspond to different preset lengths of finished strip, avoiding misjudgment caused by the operator's experience in adjustment, which may lead to product quality problems.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
