Description

Technical Field

[0001] This invention relates to the field of rotary disc cutter cutting technology, specifically to an electric vehicle frame processing and cutting system. Background Technology

[0002] In the field of electric vehicle manufacturing, the frame, as a key component, is generally assembled from metal tubes through a series of processes such as bending, perforation, and welding. Cutting the metal tubes is a core step in frame processing. Among these processes, disc cutter cutting technology is widely used in the industry due to its ease of operation and controllable cost. For cutting single metal tubes, the existing equipment's workflow is relatively mature: after the feeding device transfers the metal tube to the cutting table, the clamping tool fixes the metal tube, and then the rotating disc cutter moves downward under the equipment's drive to complete the cutting operation of the metal tube. The cut metal tube segment is removed by the unloading device, and the equipment then enters the next feeding-cutting cycle.

[0003] To further improve processing efficiency, the industry often adopts the method of cutting multiple metal tubes simultaneously. Specifically, multiple metal tubes are directly bundled together and transported to the disc cutter cutting table via a feeding device. After the tube bundle is clamped by a clamping tool, the disc cutter is controlled to move downward to complete the cutting. However, this existing technology has obvious limitations: On the one hand, the cross-sectional size of the tube bundle formed by the bundle of multiple metal tubes is large. The disc cutter needs to cut from the top of the tube bundle layer by layer to the bottom. The cutting stroke is long and the cutting depth is large, resulting in a long time for a single cut and difficulty in improving the overall cutting efficiency. On the other hand, the bundled metal tubes are concentrated in a concentrated state. During cutting, the force area of ​​the disc cutter is highly concentrated at the corresponding position of the tube bundle, and the pressure cannot be distributed. This can lead to the tool being subjected to a high load momentarily due to excessive local force, and the tool may also be subjected to local overload due to the uneven distribution of metal tubes inside the tube bundle. The combination of these two factors will accelerate tool wear and significantly shorten the service life of the disc cutter. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes an electric vehicle frame processing and cutting system. This invention uses a pressure seat to spread out and press multiple metal tubes before the disc cutter cuts, thereby reducing the cutting depth of the disc cutter and improving cutting efficiency. On the other hand, it allows the disc cutter to cut in a distributed manner, avoiding excessive local stress and damage caused by concentrated cutting. In addition, after the metal tubes are spread out, more metal tubes can be accommodated for cutting, increasing the cutting volume and cutting efficiency.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 9 As shown, the present invention includes the following embodiments: Example 1: An electric vehicle frame processing and cutting system includes a cutting platform 1 and a frame 2 on the cutting platform 1; the frame 2 is laterally driven to a cutting arm 3 that can move up and down; a disc cutter 34 is driven to the lower position of the cutting arm 3; upper sliding grooves 31 are provided on both sides of the cutting arm 3; an upper slider 32 is slidably connected to the upper sliding groove 31; the upper surface of the upper slider 32 is connected to the upper end of the upper sliding groove 31 by an upper spring 33; pressure seats 4 are provided on both sides of the cutting arm 3 and are fixedly connected to the upper slider 32; the lower surface of the pressure seat 4 is configured as an upper arc surface 41 adapted to the curvature of the disc cutter 34; a support 5 is embedded on the upper surface of the cutting platform 1 and located directly below the pressure seat 4; a lower arc surface 61 adapted to the upper arc surface 41 is provided on the upper position of the support 5; an intercepting strip 7 is provided at the end of the upper arc surface 41.

[0022] In this embodiment, the portions of the two upper sliders 32 extending out of the upper slide groove 31 are fixedly connected by an n-shaped strip 35.

[0023] In the initial state, the pressure seat 4 is far from the support 5. The feeding device (not shown in the figure, this is existing technology and will not be described in detail here) gathers multiple metal tubes and inserts them between the pressure seat 4 and the support 5. After the multiple metal tubes have moved a suitable distance along their length, the feeding device stops working. Then, the clamping of the metal tubes by the feeding device is released, and the cutting arm 3 is controlled to move downward. The cutting arm 3 is connected to the frame 2 through a structure such as a lead screw and slider pair, or to the inside of the frame 2 through components such as an electric push rod (not shown in the figure), so that the cutting arm 3 can move vertically along the frame 2. The cutting arm 3 will drive the disc cutter 34 to move downward. The disc cutter 34 is driven to rotate by the first motor (not shown in the figure) inside the cutting arm 3. During the downward movement of the cutting arm 3, the upper slider 32 in the upper slide groove 31 will move downward. During the downward movement of the upper slider 32, the pressure seat 4 will move downward. During the downward movement of the pressure seat 4, the upper arc surface 41 will come into contact with the multiple metal tubes in the gathered state. The pressure seat 4 will cause the intercepting strip 7 to intercept on both sides of the multiple metal tubes, thereby achieving lateral limitation of the metal tubes. During the downward movement of the pressure seat 4, the upper arc surface 41 will squeeze the multiple metal tubes. After being compressed, the multiple gathered metal tubes will spread out laterally along the gap between the upper arc surface 41 and the lower arc surface 61 until the metal tubes come into contact with the inside of the intercepting strip 7, at which point the pressure seat 4 will stop moving downward. In this way, the pressure seat 4 can both spread out the multiple gathered metal tubes and press them together.

[0024] The uniform spacing between the upper arc-shaped surface 41 and the lower arc-shaped surface 61 ensures that the multiple metal tubes are pressed more evenly. Due to the large elastic force of the upper spring 33, the downward movement of the cutting arm 3 transmits force to the upper slider 32 via the upper spring 33, and then to the pressure seat 4 via the upper slider 32. Thus, the disc cutter 34 does not cut before the metal tubes are pressed. Furthermore, since the portions of the two upper sliders 32 extending out of the upper groove 31 are fixedly connected by the n-shaped strip 35, the two pressure seats 4 can move downwards synchronously, ensuring the metal tubes are pressed evenly. The tubes are pressed together synchronously. After the multiple metal tubes are spread out and pressed, the cutting arm 3 will drive the disc cutter 34 to move down. The curvature of the disc cutter 34 is adapted to the upper arc surface 41. Therefore, the disc cutter 34 can evenly contact the multiple metal tubes spread out in an arc shape. During the cutting process of the multiple metal tubes spread out in an arc shape, compared with the original method of cutting multiple metal tubes together, on the one hand, the feed of the disc cutter 34 is reduced, and the cutting efficiency is higher. On the other hand, the force of the disc cutter 34 is dispersed during the cutting process, reducing the probability of damage to the disc cutter 34.

[0025] After the metal tube is cut, the cutting arm 3 moves the disc cutter 34 upward. The upper slider 32 moves relative to the upper slide groove 31 to the lower end of the upper slide groove 31. Then, the upper slider 32 moves upward along with the cutting arm 3. The upper slider 32 moves the pressure seat 4 and the intercepting bar 7 upward. The pressure seat 4 releases its contact with the metal tube, thus releasing the pressure on the metal tube. Then, the unloading device (not shown in the figure) unloads the cut metal tube. Both the unloading and loading devices are existing technologies and will not be described in detail here. The loading and unloading of the metal tube can be done manually. The feeding process does not affect the metal tube spreading and pressing part of the present invention, so that the cutting system can be fully automatic or semi-automatic, depending on the usage requirements. However, it is worth noting that the metal tube is easy to feed and unload after it is gathered together. However, in order to improve cutting efficiency and ensure the service life of the disc cutter 34, it is necessary to spread and press the metal tube after feeding. In addition, since the upper limit of the cutting depth of the disc cutter 34 itself is limited, the cutting feed is reduced after the metal tube is spread out, so that more metal tubes can be accommodated for simultaneous cutting, thereby increasing the cutting volume and cutting efficiency of the metal tube. The present invention uses a pressure seat 4 to spread out and press multiple metal tubes before the disc cutter 34 cuts, thereby reducing the cutting depth of the disc cutter 34 and improving the cutting efficiency. On the other hand, it allows the disc cutter 34 to cut in a dispersed manner, avoiding damage caused by excessive local stress due to concentrated cutting. In addition, after the metal tubes are spread out, more metal tubes can be accommodated for cutting, increasing the cutting volume and cutting efficiency.

[0026] Example 2: The support 5 is provided with an upward through groove 51 on its side; multiple support blocks 52 are slidably connected in the groove 51; two adjacent support blocks 52 are in contact with each other; the lower end of the support block 52 is connected to the lower inner wall of the groove 51 by a lower spring 53; a deformable lower arc-shaped piece 6 is fixedly connected to the middle position of the upper surface of the support 5; the upper surface of the lower arc-shaped piece 6 is a lower arc-shaped surface 61.

[0027] In this embodiment, the two supports 5 are provided with a locking groove 54 communicating with the support groove 51 on the side away from each other; a locking bar 55 is slidably connected in the locking groove 54; the locking bar 55 is rotatably connected to a bolt 56; the bolt 56 is threadedly connected to the support 5; and the locking bar 55 and the support block 52 are provided with interlocking teeth at their contact positions.

[0028] Before the cutting system cuts the metal tubes, the curvature of the lower arc surface 61 is adjusted according to the outer diameter of the metal tubes to ensure that the multiple metal tubes are evenly spread out and pressed after being compressed. The adjustment standard is that the distance between the upper arc surface 41 and the lower arc surface 61 is equal at all positions after the metal tubes are compressed. Specifically, the multiple metal tubes are first placed on two supports 5. The upper surface of the lower arc plate 6 is the lower arc surface 61, so the multiple metal tubes will fall on the lower arc surface 61 of the lower arc plate 6. Then, the cutting arm 3 is controlled to move down. During the downward movement of the cutting arm 3, the upper slider 32 and the pressure seat 4 will move down. The pressure seat 4 will drive the intercepting bar 7 to first intercept and limit the metal tubes laterally. Then, the bolt 56 is turned in the opposite direction to move the locking bar 55 away from the support block 52. The teeth on the locking bar 55 disengage from the teeth on the support block 52, thereby unlocking.

[0029] After the support block 52 is unlocked, it can slide up and down within the support groove 51. The support block 52 moves upward under the force of the corresponding lower spring 53, and then contacts the metal tube through the lower arc-shaped piece 6. Subsequently, the pressure seat 4 continues to move downward, and the upper arc-shaped surface 41 of the pressure seat 4 squeezes the metal tube, causing the metal tube between the upper arc-shaped surface 41 and the lower arc-shaped surface 61 to be squeezed apart. This continues until multiple metal tubes between the upper arc-shaped surface 41 and the lower arc-shaped surface 61 are observed to be evenly spread out and clamped, i.e., the distance between the upper arc-shaped surface 41 and the lower arc-shaped surface 61 is equal at all positions. Then, turning the bolt 56 in the forward direction will activate the lock. The locking bar 55 is close to the support block 52, and the teeth on the locking bar 55 engage with the teeth on the support block 52 to lock the support block 52. This fixes the contact position between the support 5 and the lower arc-shaped piece 6. Since the fixed support 5 can provide an upward support force to the metal tube, the metal tube is pressed after being moved down by the pressure seat 4, which improves the stability of the metal tube pressing. Subsequently, in the next cutting of metal tubes of the same diameter and number, multiple metal tubes can be evenly spread out and pressed. In this embodiment, by adjusting the upper end of the support 5, the cutting system can meet the cutting requirements of metal tubes of different diameters.

[0030] Example 3: Two lower arc-shaped pieces 6 are fixedly connected to the middle position of the upper surface of a single support 5; the two lower arc-shaped pieces 6 are elastic and are staggered from the pressure seat 4.

[0031] In the initial state, the lower arc-shaped plate 6 is bent inward and raised at the end relative to the middle position. Thus, after multiple metal tubes fall on the upper end of the support 5, the multiple metal tubes will be supported by the lower arc-shaped plate 6. Subsequently, the pressure seat 4 will move down and squeeze the multiple metal tubes to spread them out. During the spreading process, the lower arc-shaped plate 6 will be squeezed open. After the metal tubes are cut, the pressure seat 4 will move up and the lower arc-shaped plate 6 will be raised at the end, thereby bringing the spread and cut metal tubes back together towards the middle position and facilitating unloading and movement.

[0032] Example 4: An intercepting groove 42 is provided through the upper arc-shaped surface 41 near the end; the intercepting strip 7 is slidably connected to the intercepting groove 42; the upper end of the intercepting strip 7 is fixedly connected to the upper block 71; the lower surface of the upper block 71 is connected to the pressure seat 4 by a tension spring 72.

[0033] In this embodiment, a reinforcing groove 57 is provided on the top of the outermost support block 52 of the support groove 51; the cross section of the reinforcing groove 57 is adapted to the cross section of the intercepting strip 7, and the lower end of the intercepting strip 7 can be inserted into the reinforcing groove 57.

[0034] During the downward movement of the pressure seat 4, the pressure seat 4 will drive the intercepting strip 7 downward. The lower end of the intercepting strip 7 will align with the reinforcing groove 57, so that the lower end of the intercepting strip 7 can be inserted into the reinforcing groove 57. As the pressure seat 4 continues to move downward, the intercepting groove 42 on the pressure seat 4 will move with the intercepting strip 7, causing the tension spring 72 to be pulled. Due to the sliding between the intercepting strip 7 and the intercepting groove 42, the intercepting strip 7 can achieve the purpose of intercepting and limiting the metal tube in any gap between the pressure seat 4 and the support 5. That is, the intercepting strip 7 can intercept and limit metal tubes of different diameters, thus improving the applicability of the intercepting strip 7. After the lower end of the intercepting strip 7 is inserted into the reinforcing groove 57, the intercepting strength of the intercepting strip 7 against the metal tube is increased, and the probability of the intercepting strip 7 deforming under pressure is reduced. When the pressure seat 4 moves upward again, the tension spring 72 will pull the upper block 71 closer to the pressure seat 4 again, and the intercepting strip 7 will be pulled out from the reinforcing groove 57 as the pressure seat 4 moves upward.

[0035] Example 5: The inner wall of the interception groove 42 is provided with an avoidance groove 43; multiple driving blocks 73, which are fixedly connected to the interception strip 7, are movably connected in the avoidance groove 43; the pressure base 4 is provided with an I-shaped groove 44; the lower end of the I-shaped groove 44 passes through the middle position of the upper arc surface 41; an I-shaped block 45 is horizontally slidably connected in the I-shaped groove 44; the lower end of the I-shaped block 45 extends to the position of the upper arc surface 41; the left and right ends of the I-shaped groove 44 are connected to the avoidance groove 43; the left and right ends of the I-shaped block 45 extend into the avoidance groove 43; the contact positions of the driving block 73 and the I-shaped block 45 are both arc-shaped; the driving blocks 73 on the two corresponding interception strips 7 are staggered in the vertical direction.

[0036] After the metal tube is placed on the lower arc surface 61 of the lower arc plate 6, the pressure seat 4 will be controlled to drive the lower end of the intercepting bar 7 to abut against the support block 52. The intercepting bar 7 can laterally intercept and limit the metal tube between the upper arc surface 41 and the lower arc surface 61. As the pressure seat 4 continues to move downward, the intercepting groove 42 on the pressure seat 4 will slide relative to the intercepting bar 7. The driving blocks 73 on the left and right intercepting bars 7 will alternately squeeze the I-shaped block 45. After the driving block 73 on the left-hand intercepting bar 7 squeezes the left end of the I-shaped block 45, the I-shaped block 45 will slide to the right in the I-shaped groove 44. The right-hand intercepting bar After the driving block 73 on the 7 presses the right end of the I-shaped block 45, the I-shaped block 45 will slide to the left in the I-shaped groove 44. Under the alternating pressing of the driving blocks 73 on the left and right intercepting bars 7, the I-shaped block 45 will slide left and right in the I-shaped groove 44. The lower end of the I-shaped block 45 will slide left and right. During the downward movement of the pressure seat 4, the lower end of the I-shaped block 45 will be triggered to slide left and right, so as to push the gathered metal tube in the left and right direction, thereby spreading the gathered metal tube more quickly. Some elastic protrusions can be set on the lower end of the I-shaped block 45 to increase friction and improve the pushing effect of the lower end of the I-shaped block 45 on the metal tube.

[0037] Furthermore, the top and bottom of the I-shaped block 45 are horizontally elastically slidably connected. Specifically, a second horizontal groove (not labeled in the figure) is provided at the middle position of the top of the I-shaped block 45; the bottom of the I-shaped block 45 is slidably connected in the second horizontal groove, and the bottom of the I-shaped block 45 is connected to the second horizontal groove through a second spring (not labeled in the figure). In this way, on the one hand, the lower end of the I-shaped block 45 is satisfied with the need to move the metal tube, and on the other hand, during the pressing process, the lower end of the I-shaped block 45 can be pressed back and adapt to the upper arc surface 41, ensuring the pressing effect of the metal tube.

[0038] Example 6: A groove 58 is provided at the upper end of the support block 52; the width of the groove 58 is adapted to the width of the pressure seat 4.

[0039] For cutting a small number of single metal tubes or tubes that cannot fill the gap between the upper arc surface 41 and the lower arc surface 61, the control bolt 56 drives the locking bar 55 to unlock the support block 52. The outermost support block 52 does not have a groove 58, while the other support blocks 52 have grooves 58 at their upper ends. The lower arc plate 6 will gather the single or small number of metal tubes towards the middle position. As the pressure seat 4 moves down, the single metal tube is pressed and the small number of metal tubes are spread out. The end of the lower arc plate 6 will be pushed upward by the corresponding support block 52 and cross the upper arc surface 41 of the pressure seat 4 to limit the single or small number of metal tubes. Finally, tighten the bolt 56 to lock the support block 52. In this embodiment, the curvature of the lower arc surface 61 is smaller than that of the upper arc surface 41, so the pressure seat 4 can cross the end of the lower arc plate 6 to spread and press the metal tubes. Thus, this cutting system can be used for cutting single or small numbers of metal tubes and has stronger functionality.
