Description

TECHNICAL FIELD

[0002] The machining process of existing automobile pipe accessories (such as short pipes, short pipe joints, and elbow pipe joints) is in a scattered manner and needs to be completed in stages: first, long pipe materials are transported to independent cutting equipment through a feeding device to be cut into short pipes of a preset length; then, the short pipes need to be manually transported or transferred to a flaring device by an additional conveying mechanism for end flaring treatment; if an elbow pipe joint needs to be made, the short pipes need to be transferred again to an elbow pipe device to complete the bending forming.

[0034] The drawings are combined Figure 2 and the drawings Figure 5 As shown, the cutting mechanism 4 includes a lifting table 41, a cylinder 42, a motor 43 and a saw blade 44, the lifting table 41 is slidably arranged on the top table 26 at the top of the frame body 2, the cylinder 42 is fixed to the top table 26, the output end of the cylinder 42 is connected with the lifting table 41, the motor 43 is arranged in the lifting table 41, the output end of the motor 43 is provided with a gear 431, and the saw blade 44 is rotatably arranged at the bottom of the lifting table 41 and provided with a gear 441 engaged with the gear 431 at the rear side.

[0035] The drawings are combined Figure 3 , the drawings Figure 5 , the drawings Figure 6 and the drawings Figure 7As shown, the bottom of the lifting platform 41 is provided with an extension rod 411, the extension rod 411 is provided with a top block 45 and a movable plate 46, the top block 45 is transversely slidably arranged in the groove of the extension rod 411, the top block 45 is matched with the transmission pipe 344, the movable plate 46 is longitudinally slidably arranged in the groove on the inner side of the extension rod 411, the rear side of the top block 45 is provided with a top rod 451, the rear side of the top block 45 is provided with a spring I 452 connected with the extension rod 411, the rear side of the extension rod 411 and the movable plate 46 are both provided with through holes allowing the top rod 451 to extend out, the movable plate 46 is provided with an adjusting platform 461, the front side of the top platform 26 and the outer side of the clamping plate 341 are respectively provided with a positioning platform I 27 and a positioning platform II 346 matched with the adjusting platform 461.

[0036] The accompanying drawings are incorporated in and constitute a part of this specification. Figure 7 As shown, the bottom of the lifting platform 41 is provided with an extension rod 411, the extension rod 411 is provided with a top block 45 and a movable plate 46, the top block 45 is transversely slidably arranged in the groove of the extension rod 411, the top block 45 is matched with the transmission pipe 344, the movable plate 46 is longitudinally slidably arranged in the groove on the inner side of the extension rod 411, the rear side of the top block 45 is provided with a top rod 451, the rear side of the top block 45 is provided with a spring I 452 connected with the extension rod 411, the rear side of the extension rod 411 and the movable plate 46 are both provided with through holes allowing the top rod 451 to extend out, the movable plate 46 is provided with an adjusting platform 461, the front side of the top platform 26 and the outer side of the clamping plate 341 are respectively provided with a positioning platform I 27 and a positioning platform II 346 matched with the adjusting platform 461.

[0037] The core of the cutting mechanism 4 is to solve the key problems of "accurate positioning" and "stable cutting" in the pipe cutting process. Through the linkage cooperation between structures, the secondary confirmation and locking of the pipe clamping state are realized first, so as to avoid the pipe deviation caused by loose clamping during cutting, then the saw blade is driven to complete efficient cutting, and the coordination between cutting action and clamping mechanism is ensured to prevent the saw blade from being miscontacted with the workpiece in the non-cutting state.

[0038] In the specific working process, when the pipe is sent to the clamping mechanism 34 below the cutting mechanism 4 by the feeding device 1, the cylinder I 42 drives the lifting platform 41 to descend, so that the extension rod 411 is inserted into the gap between the transmission pipe 344 and the clamping plate 341. When the extension rod 411 moves downward, the top block 45 contacts the transmission pipe 344. Since the movable plate 46 is at the bottom position of the rear groove of the extension rod 411 at this time, the through hole on the movable plate 46 is misaligned with the top rod 451, that is, the movable plate 46 prevents the rear movement of the top block 45, so that the top block 45 drives the transmission pipe 344 to move outward, so that the two clamping plates 341 are opened, and the pipe groove is conveniently put into the clamping groove 342. Then the lifting platform 41 continues to move downward, and after the top block 45 leaves the transmission pipe 344, the clamping plate 341 is reset by the tension spring 345 to clamp the pipe end.

[0039] As the lifting platform 41 continues to move downward, the arc-shaped groove at the bottom of the arc-shaped buckle 47 engages with the top of the two clamping plates 341, causing the clamping plates 341 to rigidly clamp the pipe, preventing the pipe from changing its position in the clamping hole or even falling out of the clamping hole due to vibration during the subsequent cutting process. As the lifting platform 41 continues to move downward, the saw blade 44 driven by the second motor 43 cuts the pipe, and the cut short pipe remains in the clamping hole. During this process, the positioning rod 471 extends into the inside of the lifting platform 41, compressing the second spring 472.

[0040] As the lifting platform 41 descends to the bottom, the saw blade 44 has already cut the pipe. As the extension rod 411 descends with the lifting platform 41, the adjusting platform 461 on the movable plate 46 moves down to the positioning platform 346 on the outer side of the clamping plate 341. Blocked and limited by the positioning platform 346, the movable plate 46 stops descending, causing it to move upward relative to the top block 45. Finally, the through hole on the movable plate 46 coincides with the top rod 451. When the lifting platform 41 rises and resets, the friction between the movable plate 46 and the groove on the rear side of the extension rod 411 keeps the movable plate 46 in a certain position relative to the extension rod 411. Since the elastic force of the first spring 452 is much smaller than that of the tension spring 345, the top... When block 45 passes through transmission tube 344, top block 45 is blocked by transmission tube 344 and moves backward, hidden in the through hole of extension rod 411, compressing spring 452. Top rod 451 passes through the through hole on movable plate 46, preventing top block 45 from pushing transmission tube 344 to open clamping plate 341 holding short tube. When lifting platform 41 rises to the highest position, it is blocked by positioning platform 27. Adjusting platform 461 stops moving upward, and movable plate 46 moves downward relative to top block 45, so that movable plate 46 is reset. The through hole on movable plate 46 and top rod 451 return to the misaligned state. At this time, extension rod 411 leaves the range of motion of clamping mechanism 34.

[0041] Combined with appendix Figure 3 As shown, the flaring mechanism 5 includes a hydraulic cylinder 51. Two hydraulic cylinders 51 are symmetrically arranged on the support frame 22. The output end of the hydraulic cylinder 51 is provided with a flaring platform 52. The flaring platform 52 is provided with a limiting rod 53 that restricts the rotation of the clamping plate 341.

[0042] After the clamping mechanism 34 rotates to the position of the flaring mechanism 5 via the displacement plate 32, the hydraulic cylinder 51 drives the flaring platform 52 to move toward the short pipe. Since the cutting mechanism 4 puts the clamping mechanism 34 in a hard clamping state before the cutting operation, the short pipe is kept in a preset position in the clamping hole. The flaring platforms 52, which move symmetrically in opposite directions, simultaneously contact both ends of the short pipe and are inserted into the through hole of the short pipe. The end of the short pipe is subjected to the pressure of the flaring platform 52, thereby flaring the end. The limiting rod 53 set on the flaring platform 52 moves to both sides of the clamping plate 341 when the flaring platform 52 moves forward, preventing the clamping plate 341 from opening, thereby preventing the flaring platform 52 from moving the short pipe when it is reset, thus causing the short pipe to disengage from the clamping hole.

[0043] Fig. 2 shows the bending mechanism 6 in the working position Figure 8 Fig. 3 shows the bending mechanism 6 in the working position Figure 9 As shown in Fig. 1, the bending mechanism 6 comprises a guide frame 61, a hydraulic cylinder 62, a transmission platform 63, a receiving groove platform 64 and a stamping part 65. The guide frame 61 is fixed on the base 21. The hydraulic cylinder 62 is arranged at the bottom of the guide frame 61. The transmission platform 63 and the receiving groove platform 64 are slidably arranged in the sliding groove 611 on the inner side of the guide frame 61. The output end of the hydraulic cylinder 62 is connected with the transmission platform 63 through the through hole at the bottom of the guide frame 61. The top of the transmission platform 63 is matched with the bottom of the receiving groove platform 64. The transmission platform 63 is provided with transmission rods 631 on both sides. The stamping part 65 comprises a stamping platform 651. The stamping platform 651 is provided with connecting rods 652 on both sides. The connecting rods 652 are hingedly connected with the transmission rods 631. The transmission rods 631 pass through the longitudinal grooves 612 on both sides of the guide frame 61. The transmission rods 631 are provided with vertical rods 632. The vertical rods 632 are provided with inclined pushing platforms 633 on the top. The inclined pushing platforms 633 are matched with the transmission pipe 344.

[0044] The stamping working principle of the bending mechanism 6 is as follows: the hydraulic cylinder 62 pushes the transmission platform 63 to rise. During the rising process of the transmission platform 63, the receiving groove platform 64 is driven to move up after being contacted. The inclined pushing platform 633 rises with the transmission platform 63. After the inclined pushing platform 633 is contacted with the transmission pipe 344, the transmission pipe 344 is pushed to open the clamping plate 341, so that the short pipe falls on the receiving groove platform 64. Then, the hydraulic cylinder 62 drives the transmission platform 63 to fall. The receiving groove platform 64 falls in the sliding groove 611. After the receiving groove platform 64 is contacted with the inner protrusion of the sliding groove 611, the falling is stopped. The transmission platform 63 continues to fall. The stamping part 65 falls under the driving of the transmission rod 631, so that the stamping platform 651 is pressed to the short pipe, so that the short pipe is bent to become a bent pipe joint.

[0045] Fig. 2 shows the bending mechanism 6 in the working position Figure 2 Fig. 3 shows the bending mechanism 6 in the working position Figure 8 Fig. 4 shows the bending mechanism 6 in the working position Figure 9 As shown in Fig. 1, the guide frame 61 is provided with a guide groove 613 on the outer side.

The fixing part 614 is provided with an ejection mechanism 66. The ejection mechanism 66 comprises an obliquely arranged hydraulic cylinder 661. The base 21 is provided with a receiving platform 25 of the hydraulic cylinder 661. The output end of the hydraulic cylinder 661 is provided with an ejection pushing platform 662. The rear side of the guide frame 61 is provided with an ejection groove 615.

[0046] The discharging working principle of the pipe bending mechanism 6 is as follows: during the lifting of the transmission table 63, the stamping part 65 is lifted with the transmission table 63, the guide table 653 slides along the guide groove 613, during the transition of the guide table 653 from the vertical section to the horizontal section of the guide groove 613, the connecting rod 652 rotates, so that the stamping table 651 is away from above the receiving groove table 64, preventing the falling of the short pipe, after the receiving groove table 64 is lifted to a certain position, the cylinder two 661 pushes the discharging push table 662 to move obliquely upward, so that the discharging push table 662 pushes the pipe joint to fall into the discharging groove 615, realizing the discharging of the pipe joint.

[0047] In the specific implementation of the present application, the pipe end is extended into the clamping hole of the displacement mechanism 3 through the feeding device 1, then the copper pipe is cut into a short pipe through the cutting mechanism 4, the short pipe is moved to the flaring mechanism 5 through the rotating displacement disc 32, the short pipe end is flared to become a short pipe joint, the short pipe joint is transferred to the pipe bending mechanism 6, the short pipe joint is pressed into a pipe joint through the pipe bending mechanism 6, realizing the synchronous processing of the pipe in multiple processes, according to the need, the flaring mechanism 5 or the pipe bending mechanism 6 can be omitted, the discharging structure of the pipe bending mechanism 6 is retained, and the automobile pipe fittings such as the short pipe, the short pipe joint, the short pipe joint and the pipe joint can be produced.
