Description

Technical Field

[0001] This application relates to the field of automotive parts manufacturing and processing technology, and in particular to a cutting device for automotive parts processing. Background Technology

[0002] Metal pipes used in automotive piping systems need to be cut into sections of the required length according to assembly requirements, and disc cutting is a common processing method in pipe processing. Most existing pipe cutting equipment uses a single disc cutter to cut the pipe directly in one go. During the process of the disc abrasive wheel directly and completely cutting the pipe, the disc cutter usually feeds in a straight line in one direction. Because the saw disc has an impact force on the pipe, defects such as flattening and tilting of the cross-section are prone to occur at the pipe end during the cutting process, which increases the difficulty and time of subsequent pipe end grinding operations, thereby reducing the overall production efficiency of the parts. Summary of the Invention

[0003] The main purpose of this application is to provide a cutting device for processing automotive parts, which aims to solve the technical problem that pipe end quality defects are prone to occur during the operation of traditional cutting equipment.

[0004] To achieve the above objectives, this application provides a cutting device for processing automotive parts, comprising: a support frame; a support base, the support base being horizontally arranged; a first clamp, with multiple first clamps evenly distributed at intervals on the support base, the first clamps being used to clamp the pipe to be processed; a second clamp, one first clamp and one second clamp being used together to clamp the same pipe to be processed; a support limiting mechanism, the support limiting mechanism being used to support or limit the second clamp; a rotating mechanism, having two rotating mechanisms, both of which are mounted on the support frame; a cutting mechanism, each rotating mechanism being connected to a cutting mechanism, the two rotating mechanisms respectively driving the corresponding cutting mechanism to reciprocate, and the two cutting mechanisms oscillating alternately; a moving mechanism, the moving mechanism driving the support base to move horizontally; and a stop block, the stop block being mounted on the support frame; wherein... The first fixture includes a first support, which is mounted on a support base. The first support has an arc-shaped piece adapted to the pipe fitting to be processed, and a clamping piece is also movably mounted on the first support, with one end detachably mounted on the first support. In the initial state, the support base is in contact with the stop block, and the two cutting mechanisms are centrally symmetrically arranged. During the swinging motion of one cutting mechanism, it is used to cut a portion of the pipe fitting held by the first fixture furthest from the stop block. When the two cutting mechanisms are centrally symmetrical, the center of symmetry is horizontally offset from the axis of the arc-shaped piece furthest from the stop block in the initial state. A moving mechanism drives the support base to move, and when the displacement is the distance between the center of symmetry of the two cutting mechanisms and the axis of the arc-shaped piece furthest from the stop block in the initial state, the other cutting mechanism is used to cut the pipe fitting in a staggered manner during its swinging motion.

[0005] Optionally, the clamping piece includes: a connecting part, which is hinged to the first support; a clamping part, one end of which is connected to the connecting part; a first arc-shaped pad, which is disposed on the inner side of the clamping part and is used to clamp the outer wall of the pipe to be processed; and a fixing part, which is disposed at the end of the clamping part away from the connecting part.

[0006] Optionally, the first clamp also includes a locking assembly comprising a screw that passes through the fixing part and is threadedly connected to the first support.

[0007] Optionally, the second clamp includes: a second support, on which a receiving groove adapted to the pipe fitting to be processed is provided; a detachable support, which is detachably disposed on the second support; and a second arc-shaped pad, which is disposed on the detachable support and is used to clamp the outer wall of the pipe fitting to be processed.

[0008] Optionally, the second clamp also includes protrusions. The bottom of the detachable support is provided with two protrusions, and the second support is provided with two slots that are adapted to the protrusions. The two protrusions are respectively engaged in the two slots.

[0009] Optionally, the second clamp also includes a swivel ball, with a swivel ball provided at the middle position of the bottom of the second support and at the middle position of the top of the detachable support, and the swivel ball corresponding to the middle position of the receiving groove.

[0010] Optionally, the support limiting mechanism includes: a support base plate, which is horizontally mounted on the support frame; and a limiting top plate, which is horizontally mounted on the support frame. The limiting top plate is located above the support base plate, and the support base plate is used to support the universal ball at the bottom of the second support. In the initial state, the limiting top plate is offset from the axis of the arc-shaped piece furthest from the stop block. When a certain pipe to be processed is cut, the universal ball at the top of the detachable support corresponding to the pipe to be processed contacts the limiting top plate.

[0011] Optionally, the rotating mechanism includes: a mounting box, which is mounted on a support frame; a rotary motor, which is mounted on the mounting box; a main gear, which is fixedly sleeved on the outside of the output shaft of the rotary motor; a driven shaft, which is rotatably mounted on the mounting box; and a driven gear, which is fixedly sleeved on the outside of the driven shaft and meshes with the main gear.

[0012] Optionally, the cutting mechanism includes: a support rod, which is fixedly sleeved on the outside of the driven shaft; and a disc cutter, which is mounted on the support rod.

[0013] Optionally, the moving mechanism includes: a threaded strip, which is mounted on a support; a lead screw, which is rotatably mounted on a support frame and threadedly connected to the threaded strip; a drive motor, which is mounted on the support frame and whose output shaft is fixedly connected to the lead screw; a linear guide, which is horizontally mounted on the support frame; and a slider, which is fixedly connected to the support and fitted onto the linear guide.

[0014] The beneficial effects achieved by this application are as follows: This application arranges multiple sets of first and second clamps at intervals on the support base, which can clamp multiple pipe fittings to be processed at the same time, facilitating batch cutting of pipe fittings; two rotating mechanisms drive the corresponding cutting mechanisms to swing alternately, completing the pre-cutting and misaligned complete cutting of pipe fittings in separate processes; the two cuts enter from both sides of the pipe fitting axis, which helps to improve the cutting shape of the pipe end and reduce defects such as pipe end flattening and twisting deformation; at the same time, the two sets of cutting mechanisms work alternately to achieve intermittent heat dissipation and avoid the problem of overheating caused by continuous cutting by a single cutting mechanism.

[0037] Example 1 Reference Figures 1 to 12 This embodiment provides a cutting device for processing automotive parts, including a support frame 1, a support seat 2 on the support frame 1, the support seat 2 being horizontally arranged; a plurality of first clamps 3 are evenly distributed on the support seat 2, each first clamp 3 cooperating with a second clamp 4, the same pipe to be processed (straight pipe) is clamped and positioned by one first clamp 3 and one second clamp 4; a support limiting mechanism 5 is provided on the support frame 1, the support limiting mechanism 5 providing support or limiting constraint for the second clamp 4.

[0038] The support frame 1 is equipped with two sets of rotating mechanisms 6, each set of rotating mechanisms 6 is connected to a cutting mechanism 7, the two sets of rotating mechanisms drive the corresponding cutting mechanisms to swing back and forth, and the two sets of cutting mechanisms perform alternating swing cutting actions; the support frame 1 is also equipped with a moving mechanism 8, which drives the support base 2 to move horizontally as a whole, and a stop block 9 is fixedly installed on the support frame 1.

[0039] The first clamp 3 includes a first support 31, which is fixedly mounted on the support base 2. The first support 31 has an arc-shaped piece 32 inside that adapts to the outer wall of the pipe fitting to be processed (hereinafter referred to as the pipe fitting). A clamping piece 33 is also movably mounted on the first support 31. The clamping piece 33 includes a connecting part 331, a clamping part 332, a first arc-shaped pad 333, and a fixing part 334. The connecting part 331 is hinged to the first support 31, and one end of the clamping part 332 is connected to the connecting part. The connecting part 331 is connected to the clamping part 332. The first arc-shaped pad 333 is provided on the inner side of the clamping part 332. The first arc-shaped pad 333 is used to fit and press the outer wall of the pipe fitting. The clamping part 332 is provided with a fixing part 334 at the end away from the connecting part 331. The connecting part 331, the clamping part 332 and the fixing part 334 are integrally formed structures and are made of elastic materials such as polyethylene or spring steel. The clamping part 332 and the fixing part 334 are thin sheet structures. The first arc-shaped pad 333 is made of elastic materials such as rubber or silicone.

[0040] The first clamp 3 also includes a locking assembly 34, which uses a screw 341. The screw 341 passes through the fixing part 334 and is threadedly connected to the first support 31, thereby completing the locking and fixing of the clamping piece 33. Specifically, the fixing part 334 is provided with a through hole for accommodating the screw 341, and the first support 31 is provided with a threaded hole adapted to the screw 341. The screw 341 passes through the through hole and is threadedly connected to the threaded hole on the first support 31.

[0041] In the initial state, the support base 2 is in contact with the stop block 9, and the two cutting mechanisms 7 are at different angles. During the swinging process, one of the cutting mechanisms 7 is used to cut a part of the pipe held by the first clamp 3, which is furthest from the stop block 9, i.e., a partial cutting operation. In the initial state, the two cutting mechanisms 7 are centrally symmetrical. The center of symmetry of the two cutting mechanisms 7 when they are centrally symmetrical is horizontally deviated from the axis of the arc-shaped piece 32, which is furthest from the stop block 9 in the initial state. The support base 2 can be moved horizontally by the moving mechanism 8. When the moving displacement is the distance between the center of symmetry of the two cutting mechanisms 7 and the axis of the arc-shaped piece 32, which is furthest from the stop block 9 in the initial state, the other cutting mechanism is used to cut off the partially cut pipe during the swinging process, i.e., a secondary cutting operation.

[0042] The second clamp 4 includes a second support 41, which has a receiving groove 42 for the fitting, and the receiving groove 42 is a semi-circular groove. A detachable support 43 is detachably mounted on the second support 41, and the detachable support 43 can be completely removed from the second support 41. A second arc-shaped pad 44 is mounted on the inner side of the detachable support 43. The second arc-shaped pad 44 is made of elastic material such as rubber or silicone and is used to press against the outer wall of the fitting. Two protrusions 45 are provided at the bottom of the detachable support 43, and two slots 46 are provided on the second support 41. The protrusions 45 are adapted to the slots 46, and the two protrusions 45 are respectively inserted into the two slots 46 to realize the quick positioning and installation of the detachable support 43.

[0043] The second support 41 is equipped with a universal ball 47 at the bottom center and the detachable support 43 is equipped with a universal ball 47 at the top center. The universal ball 47 also corresponds to the center of the receiving groove 42.

[0044] The support and limiting mechanism 5 includes a support base plate 51 and a limiting top plate 52. Both the support base plate 51 and the limiting top plate 52 are horizontally mounted on the support frame 1. The limiting top plate 52 is positioned above the support base plate 51. The end of the limiting top plate 52 facing the stop block 9 is machined with a rounded corner to facilitate the introduction of the universal ball 47 under the limiting top plate 52. The support base plate 51 is used to support the universal ball 47 at the bottom of the second support 41. When the equipment is in the initial state, the position of the limiting top plate 52 is offset from the axis of the arc-shaped piece 32 furthest from the stop block 9. When a secondary cutting operation is performed on a certain pipe fitting, the universal ball 47 at the top of the detachable support 43 corresponding to the pipe fitting contacts the limiting top plate 52 to achieve vertical limiting of the second clamp 4, which is used to suppress the jumping caused by the cutting impact.

[0045] The rotating mechanism 6 includes a mounting box 61, which is fixedly mounted on the support frame 1. A rotary motor 62 is mounted on the mounting box 61, and a main gear 63 is fixedly sleeved on the output shaft of the rotary motor 62. A driven shaft 64 is rotatably mounted on the mounting box 61 and is rotatably mounted on the mounting box 61 via bearings. A driven gear 65 is fixedly sleeved on the outside of the driven shaft 64, and the driven gear 65 and the main gear 63 mesh with each other for transmission. The rotary motor 62 drives the main gear 63 to rotate, and the main gear 63 drives the driven gear 65 to rotate, which in turn drives the driven shaft 64 to reciprocate. Specifically, the rotary motor 62 is a stepper motor, which can rotate in both directions and can precisely control the rotation angle. The transmission ratio between the main gear 63 and the driven gear 65 is greater than one, which enables the driven shaft 64 to reciprocate, thereby realizing the reciprocating oscillation of the cutting mechanism 7.

[0046] The cutting mechanism 7 includes a support rod 71 and a disc cutter 72. The support rod 71 is fixedly sleeved on the outside of the driven shaft 64, and the disc cutter 72 is fixedly mounted on the support rod 71. The driven shaft 64 of the rotating mechanism 6 reciprocates, driving the support rod 71 and the disc cutter 72 to reciprocate synchronously. The high-speed rotating saw disc of the disc cutter 72 is used to cut the pipe. The two rotating mechanisms 6 drive the two disc cutters 72 to swing alternately. One disc cutter 72 completes the partial cutting operation of the pipe, and the other disc cutter 72 performs a secondary cutting operation after the pipe is offset.

[0047] like Figure 2 As shown, in the initial state of the equipment, the support base 2 and the stop block 9 are in contact with each other and are limited. At this time, the support rod 71 of the cutting mechanism 7 connected to the upper rotating mechanism 6 forms a 60-degree angle with the vertical direction. The support rod 71 can reach the vertical state by rotating 60 degrees clockwise. The support rod 71 of the other cutting mechanism 7 also forms a 60-degree angle with the vertical direction. It can also reach the vertical state by rotating 60 degrees clockwise. At this time, the two cutting mechanisms 7 are arranged in a centrally symmetrical manner.

[0048] Multiple pipe fittings are sequentially fixed inside each of the first clamps 3. Specifically, the pipe fittings are placed inside the arc-shaped piece 32, and the position of the pipe fittings is adjusted so that they can be cut to the required length. At the same time, the pipe fittings are made to cooperate with the receiving groove 42 of the second support 41, the clamping piece 33 is closed, the screw 341 is tightened, and the first arc-shaped pad 333 is used to press one side of the pipe fitting. Then, the protrusion 45 of the detachable support 43 is aligned with the slot 46 and inserted, and the second arc-shaped pad 44 is used to press against the outer wall of the pipe fitting to complete the clamping and fixing of a single pipe fitting. During this clamping process, the second clamp 4 only needs to clamp the pipe fitting in the appropriate position, without the need for extremely high-precision alignment. Of course, the universal ball 47 at the bottom of the second support 41 needs to be supported by the support base plate 51.

[0049] In the initial state, the pipe fitting is clamped and fixed on the first clamp 3, which is farthest from the stop block 9; the upper rotating mechanism 6 drives the corresponding support rod 71 to rotate 60 degrees clockwise and swing to a vertical state. During this swing, the cutting mechanism 7 completes the first local cutting operation on the pipe fitting. During the first local cutting, the universal ball 47 on the detachable support 43 corresponding to the pipe fitting does not contact the limiting top plate 52. Only the universal ball 47 at the bottom of the second support 41 is supported by the support bottom plate 51.

[0050] During partial cutting, the upper cutting mechanism 7 swings downward at an angle. The cutting mechanism 7 applies a downward squeezing force to the pipe, which directly presses the pipe against the lower support plate 51. The resulting downward pressure is sufficient to ensure the pipe is positioned. Therefore, the first pre-cutting process does not require the top plate 52 to constrain the detachable support 43, reducing the vertical positioning requirements of the second clamp 4. When the operator clamps the pipe, they only need to ensure that the pipe is effectively clamped, thus improving the feeding efficiency.

[0051] After the partial cutting of the pipe fitting is completed, the moving mechanism 8 drives the support base 2 to move horizontally. The displacement is equal to the offset distance between the symmetrical centers of the two cutting mechanisms 7 and the axis of the farthest arc-shaped piece 32 of the stop block 9 in the initial state. During the horizontal movement of the support base 2, the universal ball 47 at the top of the detachable support 43 transitions along the rounded corner of the end of the limiting top plate 52 and is guided into the lower surface of the limiting top plate 52, i.e. Figure 10 As shown in the diagram; the rounded corner transition helps to prevent the omnidirectional ball 47 from getting stuck or bumping during the movement process.

[0052] After being moved into position, the top omnidirectional ball 47 of the detachable support 43 abuts against the limiting top plate 52, while the bottom omnidirectional ball 47 remains supported by the supporting bottom plate 51, with the omnidirectional ball 47 clamped between the limiting top plate 52 and the supporting bottom plate 51; subsequently, another rotating mechanism 6 (the lower rotating mechanism 6) drives the corresponding cutting mechanism 7 to rotate 60 degrees clockwise, which is... Figure 11 As shown, the secondary cutting operation of the pipe is completed. During the secondary cutting operation, the swing trajectory of the disc cutter 72 deflects obliquely upward, and the cutting will generate an upward cutting force on the pipe. If there is no upper constraint, the pipe and the second clamp may jump or move upward. At this time, the limiting top plate 52 and the supporting bottom plate 51 form a limit on the second clamp 4 through the upper and lower universal balls 47, which counteracts the upward impact load brought by the secondary cutting, suppresses the clamp jumping, and ensures the stability of the pipe during the secondary cutting process. During this cutting process, the pipe adjacent to the pipe (not yet processed) will not come into contact with the cutting mechanism 7 connected to the upper rotating mechanism 6.

[0053] This equipment employs a two-stage cutting process, with each cut entering from both sides of the pipe's axis. The first partial cut involves a downward-angled entry, applying downward pressure to the pipe. The second cut involves an upward-angled entry, applying upward pressure to the pipe. The two cuts apply pressure in opposite directions, with staggered cutting positions, resulting in a misaligned cut. Unidirectional cutting forces can easily cause pipe twisting and warping deformation. However, the pressure generated by the second cut helps correct the deformation caused by the first cut, effectively suppressing twisting and warping deformation caused by unidirectional cutting forces. This ensures the overall roundness and pipe end shape after cutting, reducing defects such as flattening and deformation at the pipe end.

[0054] After the pipe is completely cut, the cut finished pipe section, together with the corresponding second clamp 4, can be moved out from between the limiting top plate 52 and the supporting bottom plate 51 to obtain an automotive pipe that meets the fixed length requirements. The automotive pipe that meets the fixed length requirements can be removed by disassembling the detachable support 43. At the same time, the other section of the cut pipe can also be removed by unscrewing the corresponding screw 341.

[0055] When entering the next cutting cycle, the upper rotating mechanism 6 drives the corresponding cutting mechanism 7 to rotate 60 degrees counterclockwise to complete its reset. Simultaneously, the lower rotating mechanism 6 drives the corresponding cutting mechanism 7 to rotate 60 degrees counterclockwise to complete its reset. Afterwards, the moving mechanism drives the support base 2 to continue moving horizontally, the distance of which is equal to the distance between the axes of two adjacent arc-shaped pieces 32, thus sending the next pipe fitting into the cutting station. Figure 12 As shown in the diagram; during the reset swing process, the cutting mechanism 7 will not interfere with the pipe to be cut; repeat the above-mentioned partial cutting and secondary cutting actions to achieve continuous cutting of multiple pipes; after a batch of pipes has been cut and all of them have been removed from the first clamp 3 and the second clamp 4, the two cutting mechanisms 7 are reset, and the moving mechanism 8 drives the support seat 2 to move horizontally and reset, so that the support seat 2 contacts the stop block 9; at this time, repeat the above-mentioned operation to fix a batch of pipes again.

[0056] In this embodiment, after a pipe fitting is cut, the detachable support 43 can be removed to take off the cut pipe fitting. The detachable support 43 is positioned by the protrusion 45 and the slot 46, making it easy to disassemble and assemble, and convenient to pick up and put away the pipe fitting. Two disc cutters 72 are used to cut alternately. When one disc cutter 72 is performing the cutting operation, the other disc cutter 72 is in a standby intermittent state. The saw disc is separated from the workpiece and dissipates heat naturally, avoiding the continuous accumulation of heat caused by the disc cutter 72 cutting continuously. This alleviates the problem of saw disc overheating and burning wear, extends the service life of the saw disc, and reduces the defects of heat burn on the pipe fitting cut surface caused by high temperature, which helps to improve the quality of the cut surface.

[0057] Example 2 Reference Figures 1 to 5 as well as Figure 13 , Figure 14 Based on Embodiment 1, the moving mechanism 8 includes a threaded bar 81, a lead screw 82, and a drive motor 83. The threaded bar 81 is fixedly connected to the support base 2. The lead screw 82 is rotatably mounted on the support frame 1 via a bearing. The lead screw 82 passes through the threaded bar 81 and is threadedly connected to the threaded bar 81. The drive motor 83 is fixedly mounted on the support frame 1, and the output shaft of the drive motor 83 is fixedly connected to the lead screw 82. A linear guide rail 84 is horizontally arranged on the support frame 1, and a slider 85 is fitted on the linear guide rail 84. The slider 85 is fixedly connected to the side wall of the support base 2.

[0058] The drive motor 83 drives the lead screw 82 to rotate forward or reverse. With the cooperation of the slider 85 and the linear guide rail 84, the lead screw 82 drives the threaded bar 81 to generate horizontal displacement, thereby moving the support seat 2 horizontally. In the initial state, the support seat 2 is against the stop block 9 for mechanical positioning. When a staggered cutting process is required, the drive motor 83 precisely drives the support seat 2, making the movement distance of the support seat 2 equal to the horizontal offset of the axis of the farthest arc piece 32 relative to the center of symmetry of the two cutting mechanisms 7 from the stop block 9, thus achieving precise alignment of the cutting position. Subsequently, the support seat 2 can also be driven to move the distance between the axes of adjacent arc pieces 32 to switch to the next pipe fitting to reach the cutting position. After processing is completed, the drive motor 83 drives the lead screw 82 in reverse, causing the support seat 2 to retract and re-abut against the stop block 9, returning to the initial position. The drive motor 83 is a stepper motor, and the lead screw 82 uses appropriate parameters such as pitch and number of turns. By precisely controlling the number of rotations of the drive motor 83, the movement position of the support seat 2 can be precisely controlled.

[0059] Example 3 Reference Figures 1 to 5 as well as Figure 15 Based on Embodiment 2, this embodiment provides a baffle structure between each pair of adjacent first supports 31. The side of the first support 31 furthest from the second block 9 is also provided with a baffle structure. The baffle structure helps to block the cutting debris. Of course, the baffle structure will not interfere with other components during the movement of the support 2.

[0060] Meanwhile, the lead screw 82 and the linear guide rail 84 are both located inside the partial structure of the support frame 1, which helps to prevent cutting debris from entering the surface of the lead screw 82 or the linear guide rail 84.

[0061] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
