Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rotary disc cutter cutting, in particular to an electric vehicle frame machining and cutting system. BACKGROUND

[0002] In the field of electric vehicle manufacturing, the frame as a key component is generally assembled by a series of processes such as bending, perforating and welding from a metal pipe; the cutting of the metal pipe is the core link in the frame machining, and the disc cutter cutting technology is more commonly used in the industry due to its convenient operation and controllable cost; for cutting a single metal pipe, the operation process of the existing equipment has been relatively mature: the metal pipe is moved to the cutting table by the feeding device, the clamping tool fixes the metal pipe, and then the rotating disc cutter is driven downward by the equipment to complete the cutting operation of the metal pipe; the cut metal pipe segment is removed by the discharging device, and the equipment immediately enters the next cycle of feeding and cutting.

[0003] In order to further improve the machining efficiency, the industry often uses the method of cutting multiple metal pipes at the same time, which is to gather multiple metal pipes into a bundle directly, transport them to the disc cutter cutting table by the feeding device, clamp the pipe bundle by the clamping tool, and then control the disc cutter to move downward to complete the cutting; but this existing technology has obvious limitations: on the one hand, the pipe bundle formed by gathering multiple metal pipes has a large cross-sectional size, the disc cutter needs to cut from the top to the bottom of the pipe bundle layer by layer, the cutting stroke is long and deep, which results in long cutting time and difficult improvement of overall cutting efficiency; on the other hand, the gathered metal pipes are in a concentrated distribution state, and the stress area of the disc cutter is highly concentrated at the corresponding position of the pipe bundle during cutting, which cannot disperse the pressure - both the local stress being too large and the uneven arrangement of the metal pipes inside the pipe bundle can cause local overload of the cutter, and the superposition of the two factors can accelerate the wear of the cutter and significantly shorten the service life of the disc cutter.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, purposes and effects of the application easy to understand, the application is further described below in combination with specific embodiments.

[0030] As shown in the figure, the application includes the following embodiments: Figures 1 to 9

[0031] Embodiment 1: An electric vehicle frame machining and cutting system, comprising a cutting platform 1 and a frame 2 on the cutting platform 1; the frame 2 is laterally transmissionally connected with a cutting arm 3 capable of moving up and down; the cutting arm 3 is drivingly connected with a disc cutter 34 at the lower position; the cutting arm 3 is provided with upper sliding grooves 31 on both sides; the upper sliding grooves 31 are slidingly connected with upper sliding blocks 32 inside; the upper surface of the upper sliding block 32 is connected with the upper end of the upper sliding groove 31 through an upper spring 33; the cutting arm 3 is provided with pressing seats 4 fixedly connected with the upper sliding blocks 32 on both sides; the lower surface of the pressing seat 4 is provided with an upper arc-shaped surface 41 adapted to the curvature of the disc cutter 34; the upper surface of the cutting platform 1 is embedded with a support 5 located directly below the pressing seat 4; the upper position of the support 5 is provided with a lower arc-shaped surface 61 adapted to the upper arc-shaped surface 41; the end of the upper arc-shaped surface 41 is provided with an intercepting strip 7.

[0032] In this embodiment, the part of the two upper sliding blocks 32 extending out of the upper sliding groove 31 is fixedly connected through an n-shaped strip 35.

[0033] ​The pressing seat 4 is away from the support 5 in the initial state, and the loading device (not shown in the figure, which is a prior art and will not be described in detail here) gathers a plurality of metal pipes into the space between the pressing seat 4 and the support 5, and after the plurality of metal pipes are moved to a proper distance along the length direction, the work of the loading device is stopped, and then the metal pipes are clamped by the loading device, and then the cutting arm 3 is controlled to move downward, the cutting arm 3 is connected with the rack 2 through a screw block pair or connected with the inside of the rack 2 through an electric push rod (not shown in the figure), so that the cutting arm 3 can move vertically along the rack 2, the cutting arm 3 drives the disc cutter 34 to move downward, the disc cutter 34 is driven to rotate by the first motor (not shown in the figure) in the cutting arm 3, the upper sliding block 32 in the upper sliding groove 31 is driven to move downward during the downward movement of the cutting arm 3, the pressing seat 4 is driven to move downward during the downward movement of the upper sliding block 32, the upper arc surface 41 is in contact with the plurality of metal pipes in the gathering state during the downward movement of the pressing seat 4, the pressing seat 4 drives the intercepting strip 7 to intercept on both sides of the plurality of metal pipes, so as to limit the metal pipes laterally, the upper arc surface 41 extrudes the plurality of metal pipes during the downward movement of the pressing seat 4, the plurality of gathered metal pipes are dispersed laterally along the gap between the upper arc surface 41 and the lower arc surface 61 after being pressed, and the downward movement of the pressing seat 4 is stopped after the metal pipes contact the inner side of the intercepting strip 7, so that the pressing seat 4 disperses the plurality of gathered metal pipes while pressing the metal pipes.

[0034] The distance between the upper arc surface 41 and the lower arc surface 61 is uniform, so that the plurality of metal pipes are pressed more uniformly, the downward movement of the cutting arm 3 can transmit the force to the upper sliding block 32 through the upper spring 33, so as to transmit the force to the pressing seat 4 through the upper sliding block 32, so that the disc cutter 34 does not cut before the metal pipes are pressed, and the two pressing seats 4 can move downward synchronously because the parts of the two upper sliding blocks 32 extending out of the upper sliding groove 31 are fixedly connected through the n-shaped strip 35, so as to ensure that the metal pipes are pressed synchronously, the cutting arm 3 drives the disc cutter 34 to move downward after the plurality of metal pipes are spread and pressed, the curvature of the disc cutter 34 is adapted to the upper arc surface 41, so that the disc cutter 34 can uniformly contact the plurality of metal pipes spread into an arc, compared with the original cutting mode of gathering the plurality of metal pipes, on the one hand, the feeding of the disc cutter 34 is reduced, and the cutting efficiency is higher, on the other hand, the stress of the disc cutter 34 is dispersed during the cutting process, so as to reduce the damage probability of the disc cutter 34.

[0035] After the cutting of the metal pipe is completed, the cutting arm 3 drives the disc cutter 34 to move upwards, the upper sliding block 32 moves to the lower end of the upper sliding groove 31, and then the upper sliding block 32 moves upwards along with the upward movement of the cutting arm 3, the upper sliding block 32 drives the pressing seat 4 and the intercepting strip 7 to move upwards, the pressing seat 4 is separated from the metal pipe, and the pressing of the metal pipe is released, and then the unloading device (not shown in the figure) unloads the cut metal pipe, the unloading device and the feeding device are prior art, and will not be described here, and the feeding and unloading of the metal pipe can be manual feeding, which does not affect the metal pipe spreading and pressing part of the present application, so that the cutting system can be fully automatic or semi-automatic, and the specific use requirement is matched, but it is worth noting that the metal pipe is gathered for easy feeding and unloading, but in order to improve the cutting efficiency and ensure the service life of the disc cutter 34, it is necessary to spread and press the metal pipe, and in addition, due to the limited upper limit of the cutting depth of the disc cutter 34, the spreaded metal pipe reduces the cutting feed, so that more metal pipes can be accommodated for simultaneous cutting, thereby improving the cutting amount and cutting efficiency of the metal pipe.

[0036] The present application spreads and presses multiple metal pipes by the pressing seat 4 before the disc cutter 34 cuts, thereby reducing the cutting depth of the disc cutter 34 and improving the cutting efficiency, and on the other hand, the disc cutter 34 can be dispersedly cut to avoid local damage caused by excessive force caused by concentrated cutting; in addition, the spreaded metal pipe can accommodate more metal pipes for cutting, thereby improving the cutting amount and cutting efficiency.

[0037] In embodiment 2, the support 5 is laterally provided with an upwardly penetrating support groove 51; a plurality of support blocks 52 are connected in the support groove 51 and can slide up and down; two adjacent support blocks 52 are movably connected; the lower end of the support block 52 is connected to the lower inner wall of the support groove 51 through a lower spring 53; the upper surface of the support 5 is fixedly connected to a lower arc-shaped piece 6 which can be deformed; and the upper surface of the lower arc-shaped piece 6 is a lower arc-shaped surface 61.

[0038] In this embodiment, the two support 5 are provided with a lock groove 54 which is in communication with the support groove 51 on the side away from each other; a lock strip 55 is slidably connected in the lock groove 54; the lock strip 55 is rotatably connected to a bolt 56; the bolt 56 is threadedly connected to the support 5; and the contact positions of the lock strip 55 and the support block 52 are provided with teeth which can be engaged with each other.

[0039] Before the cutting system cuts the metal pipes, the curvature of the lower arc surface 61 is adjusted according to the outer diameter of the metal pipes, so as to ensure that the multiple metal pipes are evenly spread and pressed after being pressed, and the standard for adjustment is that the distance between each position of the upper arc surface 41 and the lower arc surface 61 after the metal pipes are pressed is equal. Specifically, first, the multiple metal pipes are placed on the two supports 5, and the upper surface of the lower arc piece 6 is the lower arc surface 61, so the multiple metal pipes will fall on the lower arc surface 61 of the lower arc piece 6, and then the cutting arm 3 is controlled to move downward, and the upper sliding block 32 and the pressing seat 4 are driven to move downward during the downward movement of the cutting arm 3, and the pressing seat 4 drives the intercepting strip 7 to intercept and limit the metal pipes laterally, and then the bolt 56 is twisted in the reverse direction to drive the lock strip 55 away from the supporting block 52, and the teeth on the lock strip 55 are out of contact with the teeth on the supporting block 52, so as to be unlocked.

[0040] After the supporting block 52 is unlocked, it can slide up and down in the supporting groove 51, and the supporting block 52 moves upward under the elastic force of the corresponding lower spring 53, and the supporting block 52 contacts the metal pipes through the lower arc piece 6, and then the pressing seat 4 continues to move downward, and the upper arc surface 41 of the pressing seat 4 extrudes the metal pipes, so that the metal pipes between the upper arc surface 41 and the lower arc surface 61 are extruded and spread out, and until the multiple metal pipes between the upper arc surface 41 and the lower arc surface 61 are evenly spread out and clamped, that is, the distance between each position of the upper arc surface 41 and the lower arc surface 61 is equal, the bolt 56 is twisted in the forward direction to drive the lock strip 55 close to the supporting block 52, and the teeth on the lock strip 55 are engaged with the teeth on the supporting block 52 to be locked, so as to lock the supporting block 52, so that the contact position of the support 5 and the lower arc piece 6 is fixed. Since the fixed support 5 can provide an upward supporting force to the metal pipes, the metal pipes can be pressed after the pressing seat 4 moves downward, thereby improving the stability of the metal pipes pressed, and then multiple metal pipes can be evenly spread out and pressed during the next cutting of metal pipes of the same diameter and number. The present embodiment adjusts the upper end of the support 5, so that the cutting system can meet the cutting requirements of metal pipes of different diameters.

[0041] Embodiment 3: The upper surface of the single support 5 is fixedly connected to the middle positions of the two lower arc pieces 6; the two lower arc pieces 6 are elastic and are arranged staggered with the pressing seat 4.

[0042] The end of the lower arc piece 6 in the initial state is curved inward and upward relative to the middle position, so that after the multiple metal pipes fall on the upper end of the support 5, the multiple metal pipes will be received by the lower arc piece 6, and then the pressing seat 4 will move downward to extrude the multiple metal pipes, thereby spreading out the metal pipes. The multiple metal pipes spread out during the process of extruding the lower arc piece 6, and after the cutting of the metal pipes is completed, the pressing seat 4 moves upward, and the lower arc piece 6 is upward at the end, thereby gathering and gathering the spread-out and cut metal pipes toward the middle position, thereby facilitating unloading and moving.

[0043] In the embodiment, the upper arc surface 41 is provided with an intercepting groove 42 penetrating through the upper arc surface 41 near the end position; the intercepting strip 7 is slidingly connected in the intercepting groove 42; the upper end of the intercepting strip 7 is fixedly connected with an upper block 71; the lower surface of the upper block 71 is connected with the pressing seat 4 through a tension spring 72.

[0044] In the embodiment, the top of the supporting block 52 of the outermost supporting groove 51 is provided with a reinforcing groove 57; 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 clamped into the reinforcing groove 57.

[0045] In the process of moving the pressing seat 4 downward, the pressing seat 4 drives the intercepting strip 7 to move downward, the lower end of the intercepting strip 7 is aligned with the reinforcing groove 57, so that the lower end of the intercepting strip 7 can be clamped into the reinforcing groove 57, and with the continuous downward movement of the pressing seat 4, the intercepting groove 42 on the pressing seat 4 will produce an action with the intercepting strip 7, so that the tension spring 72 is pulled, and due to the sliding of the intercepting strip 7 and the intercepting groove 42, any gap between the pressing seat 4 and the supporting seat 5 can be intercepted and limited by the intercepting strip 7, that is, the intercepting strip 7 can intercept and limit metal pipes of different diameters, thereby improving the application range of the intercepting strip 7, and after the lower end of the intercepting strip 7 is inserted into the reinforcing groove 57, the intercepting strength of the intercepting strip 7 on the metal pipe is improved, and the probability of deformation of the intercepting strip 7 under pressure is reduced; in the case of upward movement of the pressing seat 4, the upper block 71 is pulled again by the tension spring 72 to approach the pressing seat 4, and the intercepting strip 7 will be pulled out of the reinforcing groove 57 with the upward movement of the pressing seat 4.

[0046] In the embodiment, the inner wall of the intercepting groove 42 is provided with an avoiding groove 43; a plurality of driving blocks 73 fixedly connected with the intercepting strip 7 are movably connected in the avoiding groove 43; the pressing seat 4 is provided with a I-shaped groove 44; the lower end of the I-shaped groove 44 penetrates through the middle position of the upper arc surface 41; the I-shaped groove 44 is horizontally slidingly connected with an I-shaped block 45; 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 communicated with the avoiding groove 43; the left and right ends of the I-shaped block 45 extend to the avoiding groove 43; the contact positions of the driving blocks 73 and the I-shaped block 45 are arc-shaped; the driving blocks 73 on two corresponding intercepting strips 7 are staggered in the vertical direction.

[0047] After the metal pipe is placed on the lower arc surface 61 of the lower arc piece 6, the pressing seat 4 is controlled to drive the intercepting strips 7 to abut against the supporting blocks 52 at the lower ends, so that the intercepting strips 7 can laterally intercept and limit the metal pipe between the upper arc surface 41 and the lower arc surface 61. With the continuous downward movement of the pressing seat 4, the intercepting grooves 42 on the pressing seat 4 will slide relative to the intercepting strips 7. The driving blocks 73 on the left and right intercepting strips 7 will alternately press the work-shaped blocks 45. After the driving block 73 on the left intercepting strip 7 presses the left end of the work-shaped block 45, the work-shaped block 45 will slide rightwards in the work-shaped groove 44. After the driving block 73 on the right intercepting strip 7 presses the right end of the work-shaped block 45, the work-shaped block 45 will slide leftwards in the work-shaped groove 44. Under the alternate pressing of the driving blocks 73 on the left and right intercepting strips 7, the work-shaped block 45 will slide left and right in the work-shaped groove 44, and the lower end of the work-shaped block 45 will slide left and right. The lower end of the work-shaped block 45 can slide left and right during the downward movement of the pressing seat 4, so as to push the gathered metal pipe left and right, thereby spreading the gathered metal pipe faster. The lower end of the work-shaped block 45 can be provided with some elastic protrusions to increase friction and improve the pushing effect of the lower end of the work-shaped block 45 on the metal pipe.

[0048] Further, the top and lower part of the work-shaped block 45 are horizontally and elastically connected. Specifically, a second horizontal groove (not labeled in the figure) is arranged at the middle position of the top of the work-shaped block 45. The lower part of the work-shaped block 45 is slidably connected in the second horizontal groove, and the lower part of the work-shaped block 45 is connected with 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 work-shaped block 45 can meet the pushing demand of the metal pipe, and on the other hand, the lower end of the work-shaped block 45 can be reset under pressure and adapt to the upper arc surface 41 during the pressing process, thereby ensuring the pressing effect of the metal pipe.

[0049] In embodiment 6, the upper end of the supporting block 52 is provided with a groove 58, and the width of the groove 58 is adapted to the width of the pressing seat 4.

[0050] 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.
