Description

Technical Field

[0001] This utility model belongs to the technical field of punching equipment, specifically a high-precision positioning punching device for flexible metal tubes. Background Technology

[0002] Flexible metal tubes have advantages such as adjustable direction and shape retention, and have a very wide range of applications. They are specifically made of spiral-shaped metal wire, such as... Figure 1 As shown, there are of course different structures depending on different needs, but they are basically inseparable from the spiral form;

[0003] Flexible metal tubes are typically manufactured to a long length and then cut at equal intervals to different lengths. In current technology, there are no requirements for the cut, so the metal tube is usually manually held to select a certain length and then cut by a stamping machine. However, now there are requirements for the cut, and the cut position must be at the spiral groove. However, the spiral groove is extremely small. Currently, the most common method is equal-distance feeding, which involves setting the system to feed the same length of material each time. Although this method is simple, it has a large error. It can be aligned at first, but due to the cutting error, the difference in the pushing will become larger and larger, making it impossible to accurately align the cutting position. Utility Model Content

[0004] The purpose of this invention is to provide a high-precision positioning and punching device for flexible metal tubes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The base is provided with a placement groove, and the placement groove is provided with a punch corresponding to the cutter;

[0008] The laser positioning component emits at least two laser beams to simultaneously locate different positions of the metal tube cutting section in multiple directions.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please refer to Figure 1-6 ;

[0029] The punching device described in this utility model aims to achieve high-precision positioning, aligning with the cutting position before each punching to achieve accurate cutting. The flexible metal tube 41 described in this utility model is specifically made of two spiral metal wires of different diameters intertwined. The cutting position is located at the gap of the outer spiral metal wire. The cutter enters the gap and cuts off the lower spiral connection part, so only the position of the outer spiral metal wire needs to be positioned, but the cutting position is very small. Of course, there should be other similar or identical flexible metal wires, and the positioning method of this device is also applicable. Therefore, this utility model provides a new positioning method. Specifically, it includes a base 1, a laser positioning component 2, and a cutting component 3. Preferably, the laser positioning component 2 consists of two laser displacement sensors. The base 1 is provided with a placement groove 11, and the placement groove 11 is provided with a punching groove 12 corresponding to the cutter 31. In this embodiment, only the positioning for punching is described. In actual production, a feeding mechanism should be included to feed the long flexible metal tube 41 into the placement groove 11, and then fix it by an external device. This will not be described in detail here.

[0030] During operation, the metal tube 41 is placed into the placement groove 11 by a feeding mechanism. The side wall of the placement groove 11 is provided with an inclined surface to limit the metal tube 41 and prevent it from shifting left or right. Then, the laser positioning component 2 emits at least two lasers to position the cutting part 42 of the metal tube 41. It should be noted that... Figure 1 As shown, since the metal tube 41 is composed of spiral metal wire, the resulting cutting section 42 is angled, and the punched groove 12 is also staggered; multiple laser beams are emitted in different directions and irradiate the metal tube 41, as shown in the figure. Figure 3For a successful positioning, multiple lasers must simultaneously illuminate the cutting area 42. If only some lasers illuminate the cutting area 42 while another laser illuminates the metal wire, the feedback data will differ, indicating a difference in laser detection height. This suggests that the cutting area 42 has not been successfully positioned. In this case, the metal tube 41 needs to be finely adjusted by the feeding mechanism or other mechanisms until all lasers are illuminating the cutting area 42 and the feedback data is completely consistent, indicating successful positioning. Finally, the cutting component 3 extends a cutter, which first enters the cutting area (gap) and then cuts the metal tube.

[0031] After one punching is completed, the metal tube 41 is pushed forward again by the feeding mechanism, and then the cutting part 42 is positioned again using the above-described method. This ensures that the cutting part 42 can be positioned before each punching, making the cutting more accurate.

[0032] To further explain the emitted laser, the cutting part 42 of the metal tube 41 is set at an angle. The laser positioning component 2 emits two lasers, which are emitted from both sides at an angle downward toward the cutting part 42, corresponding to the two sides of the cutting part 42 of the metal tube 41 respectively. The two lasers also correspond to the groove 12. From the top view, the irradiation surface of the two lasers is in the groove 12. This allows the cutting part 42 to be aligned with the groove 12, ensuring accurate cutting.

[0033] Preferably, the cutter 31 in the cutting assembly 3 is adapted to the cutting portion 42 of the metal tube 41, for example, in an "S" shape or a "Z" shape, etc.

[0034] One embodiment of the feeding mechanism of this utility model specifically includes a fixed base 51, on which a clamping component 1 52 and a clamping component 2 53 are slidably connected. The clamping component 1 52 and the clamping component 2 53 extend to both sides of the base, and a driving component is installed on the fixed base 51. In this embodiment, the clamping component 1 52 and the clamping component 2 53 are operated independently by the driving component. First, the metal tube 41 to be cut is obtained by the clamping component and pushed in and passed through the placement position under the drive of the driving component. Then, the metal is clamped by the clamping component 2 53 on the other side. At this time, both ends of the metal tube 41 are clamped and fixed. Then, the cutting is performed by the laser positioning mentioned above. The cut part is still clamped by the clamping component 2 53. Finally, the clamping component 2 53 is released after the cut metal tube 41 is obtained by other transfer components.

[0035] In another embodiment, the clamping parts of clamping component 1 52 and clamping component 2 53 have telescopic functions. Since the metal tube 41 to be punched is relatively long, after being fixed by a clamping component, both ends are easily bent downward by gravity and cannot enter the placement position. Therefore, at the beginning, clamping component 2 53 uses the telescopic function to bypass the base 1 and reach the material acquisition end. The driving component separates clamping component 1 52 and clamping component 2 53 by a distance so that the two can clamp and fix the two ends of the metal tube 41 so that the metal tube 41 will not bend. Then, the driving component pushes the two clamping components forward synchronously so that the metal tube 41 enters the placement position. Then, clamping component 2 53 again bypasses the base 1 through the telescopic action to reach the other end and clamp the metal tube 41.

[0036] One embodiment of the drive assembly of this utility model specifically includes a mounting bracket 541, on which two drive motors 542 are mounted opposite each other. The two drive motors 542 are respectively connected to two synchronous pulley sets 543 located opposite each other on the fixed base 51. The two synchronous pulley sets 543 are respectively connected to clamping assembly one 52 and clamping assembly two 53. The drive motors 542 are arranged opposite each other, so they can be installed using only one mounting bracket 541, saving installation components.

[0037] In this utility model, clamping component 1 52 and clamping component 2 53 have the same structure, as shown in the reference. Figure 6 Taking clamping assembly 52 as an example, it specifically includes a slide 521, on which a bracket 522 is mounted. A first cylinder 523 and a fixing cover 524 are mounted on the extended end of the bracket 522. Two clamping arms 525 are rotatably connected to the fixing cover 524. In this embodiment, the two clamping arms 525 can be rotatably connected to the fixing cover 524 respectively, or they can be rotatably connected to each other and then connected to the fixing cover 524 at their central axis, both achieving the same function. A spring 526 is provided between the two clamping arms 525. A top contact block 527 is provided at the output end of the first cylinder 523 and extends into the fixing cover 524. The top contact block 527 abuts against the two clamping arms 525 and pushes the two clamping arms 525 to rotate. In this embodiment, the inner side of one end of the two clamping arms 525 is provided with an inclined surface, and the corresponding top contact block 527 is also provided with an inclined surface. When the first cylinder 523 pushes the ejector block to move forward, the top contact block 527 squeezes into the space between the two clamping arms 525, causing the two clamping arms 525 to rotate and the clamping ends of the two clamping arms 525 to come close to each other to form a clamping state. When the first cylinder 523 drives the top contact block 527 to retract, the clamping ends of the two clamping arms 525 separate from each other under the action of the spring 526, and then the clamping state is changed to the released state.
