[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Referring to Figures 1 - 4 As shown, the present invention provides an automobile exhaust pipe cutting device, which includes an operation base 1, and further includes a support assembly 2, a shearing assembly 3, a rotating and placing assembly 4 and a storage assembly 5. The support assembly 2 is used for supporting and placing pipe fittings to facilitate the advancement of the pipe fittings towards the shearing assembly 3. The shearing assembly 3 is arranged at one end of the support assembly 2. The rotating and placing assembly 4 includes a fixed disc 41. A mounting circular groove 411 is centrally formed on the surface of the fixed disc 41. A driven member 43 is arranged in the mounting circular groove 411. The driven member 43 can rotate on the fixed disc 41. A retracting member 44 is mounted on the driven member 43. The retracting member 44 can drive the clamping member 45 and the cut small section of the pipe fitting in contact with it to retract, leaving space for the rotation and storage of the small section of the pipe fitting. A clamping member 45 for fixing the end of the pipe fitting is mounted on the retracting member 44. And a pair of second driving members 42 matching the driven member 43 are symmetrically mounted on the fixed disc 41. The storage assembly 5 is arranged behind the rotating and placing assembly 4 and is used to cooperate with the rotating and placing assembly 4 to store the small sections of the pipe fittings obtained after being cut by the shearing assembly 3, avoiding the damage and deformation of the small sections of the pipe fittings. The support assembly 2 includes a first support frame 21. The first support frame 21 is fixedly installed on the operation base 1. A support platform plate 22 is fixedly installed on the first support frame 21. A plurality of first pin shafts 23 are installed at intervals in the support platform plate 22. And a conveying roller column 24 for assisting the advancement of the pipe fitting is sleeved outside each first pin shaft 23. In this way, when the pipe fitting is placed on the sequentially arranged plurality of conveying roller columns 24, it will be more smooth to push.

[0022] Among them, the shearing assembly 3 includes a second support frame 31 fixed on the operation base 1. A fixed plate 32 is fixed on the second support frame 31. Side plates are fixedly installed on the surface of the fixed plate 32. An installation inclined plate 36 is rotatably installed on the side plates through a second pin shaft 361. A machine cover 33 is installed at the front end of the installation inclined plate 36. A first rotating shaft 34 is rotatably installed in the machine cover 33. A cutting blade 35 is sleeved outside the first rotating shaft 34 and is located in the machine cover 33. A telescopic cylinder 37 is hingedly installed on the fixed plate 32. The output end of the telescopic cylinder 37 is hingedly connected to the back of the installation inclined plate 36. The telescopic output of the telescopic cylinder 37 can control the installation inclined plate 36 to rotate around the axis of the second pin shaft 361, so as to lower or lift the cutting blade 35. Lower the cutting blade 35 for cutting operations and lift the cutting blade 35 to end the cutting operation. A first driving member 38 matching the first rotating shaft 34 is installed on the installation inclined plate 36. The first driving member 38 includes a first driving motor 381. The first driving motor 381 is fixedly installed on the installation inclined plate 36. A first pulley 382 is fixedly sleeved on the output shaft of the first driving motor 381. A second pulley 384 is fixedly sleeved at the end of the first rotating shaft 34. A transmission belt 383 is connected between the second pulley 384 and the first pulley 382. The transmission belt 383 serves to transmit and connect the first pulley 382 and the second pulley 384. When the cutting blade 35 needs to rotate to cut the pipe fitting, the first driving motor 381 is started to drive the first pulley 382 to rotate. The rotation of the first pulley 382 drives the transmission belt 383 to rotate. The rotation of the transmission belt 383 can drive the second pulley 384 to rotate. The rotation of the second pulley 384 can drive the first rotating shaft 34 to rotate, so as to drive the cutting blade 35 outside the first rotating shaft 34 to rotate and achieve the purpose of rotary cutting.

[0023] In a further embodiment, referring to Figure 5 As shown, the driven member 43 includes a second rotating shaft 431 rotatably installed at the inner bottom of the installation circular groove 411. A support disc 432 is fixedly sleeved at the upper end of the second rotating shaft 431. A gear ring 433 is fixed outside the support disc 432. A third support frame 434 connected to the retracting member 44 is installed on the surface of the gear ring 433. The second driving member 42 includes a second driving motor 421 installed at the edge of the end face of the fixed disc 41. A driving spur gear 422 is fixedly installed on the output shaft of the second driving motor 421. The driving spur gear 422 is meshed and connected with the gear ring 433. When it is necessary to rotate the retracting member 44 and the clamping member 45, the second driving motor 421 is started to drive the driving spur gear 422 to rotate. The rotation of the driving spur gear 422 meshes and drives the gear ring 433 to rotate. The rotation of the gear ring 433 can drive the support disc 432 to rotate, so as to drive the support disc 432 that supports the retracting member 44 to rotate.

[0024] Since the small section of the pipe fitting after cutting is still in contact with the original pipe fitting, directly rotating the small section of the pipe fitting obtained by cutting clockwise will cause resistance or movement interference. Therefore, the following specific settings are made for the retracting member 44: The retracting member 44 includes a rectangular table plate 441 fixed on the third support frame 434. Two sliding rails 447 are symmetrically installed inside the rectangular table plate 441. An active block 442 is slidably arranged on the two sliding rails 447. The clamping member 45 is installed on the active block 442. A third driving motor 443 is installed at the bottom of the rectangular table plate 441. The output end of the third driving motor 443 is connected with a third rotating shaft 444 penetrating through the thickness of the rectangular table plate 441. The upper end of the third rotating shaft 444 is fixedly sleeved with a rotating disc 445. An inclined pull rod 446 is rotatably connected outside the rotating disc 445. One end of the inclined pull rod 446 away from the rotating disc 445 is rotatably connected with the end of the active block 442. In this way, when the third driving motor 443 is started, it drives the third rotating shaft 444 and the rotating disc 445 to rotate, so as to drive the inclined pull rod 446 to pull the active block 442, realizing the limited retraction of the active block 442 in the rectangular table plate 441, creating conditions for the rotation and storage of the small section of the pipe fitting obtained by cutting. Conversely, after the clamping member 45 is put into the abutting and limiting position of the end of the original pipe fitting again, the active block 442 only needs to be pushed to the initial position.

[0025] In this embodiment, the small section of the pipe fitting obtained after cutting is carried by the clamping member 45, first retracts to the side away from the support assembly 2, then rotates clockwise by ninety degrees. After reaching the position, the clamping member 45 releases the small section of the pipe fitting, so that the small section of the pipe fitting falls into the storage groove 571 on the transmission belt 57 along the trend. The transmission belt 57 gradually delivers, which can realize the effective storage of the sections of the pipe fitting obtained by cutting, can avoid the accidental dropping and damage of the small section of the pipe fitting obtained by cutting, and ensure the yield rate of the subsequent finished products.

[0026] In a further embodiment, referring to Figures 5 - 7As shown, the clamping member 45 includes two mounting frames 451 symmetrically mounted on the movable block 442, and the two mounting frames 451 are fixedly mounted with vertical plates 452. Two vertical moving members 457 are symmetrically mounted in the vertical plates 452. The two vertical moving members 457 are connected with supporting rods 456, and the opposite sides of the two supporting rods 456 are connected with adhesive strips 4561 through adhesive. The adhesive strips 4561 can improve the stability of the support when the two supporting rods 456 are against the inner edge of the pipe. The two supporting rods 456 and the two insert blocks 4574 are connected. The surfaces together form a good limiting effect on the end of the pipe fitting; the vertical moving member 457 includes a roller bearing 4571 installed on the inner wall of the vertical plate 452, a screw rod 4572 is rotatably installed in the roller bearing 4571, and a driven bevel gear 4576 is fixedly sleeved on the end of the screw rod 4572 facing away from the roller bearing 4571, and a vertical moving block 4573 is arranged on the outer surface of the screw rod 4572 and threadedly connected, and an embedded block 4574 is fixedly connected to the exposed end of the roller bearing 4571, and the supporting rod 456 is fixedly connected to the end of the embedded block 4574 away from the vertical moving block 4573; The clamping member 45 further includes a fourth driving motor 453 fixed to the side of the vertical plate 452. The output end of the fourth driving motor 453 is connected to a fourth rotating shaft 454 that penetrates the vertical plate 452. An active bevel gear 455 is fixedly sleeved on the outside of the fourth rotating shaft 454. The active bevel gear 455 is respectively meshed and connected with two driven bevel gears 4576. In this way, the fourth rotating shaft 454 can be driven to rotate by starting the fourth driving motor 453, and the active bevel gear 455 can be driven to rotate, so that the two driven bevel gears 4576 can be driven to rotate synchronously. The synchronous rotation of the two screw rods 4572 can drive the two vertical movement blocks 4573 to approach or move away from each other in the vertical direction, so as to achieve the purpose of limiting and releasing the ends of the pipe fittings by the two support rods 456; two groups of limit grooves 4521 are symmetrically opened on the inner side wall of the vertical plate 452, and the limit blocks 4575 are inserted and slidably connected in the two groups of limit grooves 4521. The two groups of limit blocks 4575 are respectively fixed to the upper and lower vertical movement blocks 4573, so that the two vertical movement blocks 4573 can be ensured to approach or move away from each other in the vertical direction in the vertical plate 452.

[0027] In this embodiment, during cutting, a person manually pushes one end of the pipe away from the transfer assembly 4, and the cut end of the pipe is fixedly restrained against one end of the clamping member 45. Specifically, the fourth driving motor 453 is started to drive the fourth rotating shaft 454 to rotate, and then the active bevel gear 455 is driven to rotate, so that the two driven bevel gears 4576 can be driven synchronously. In this way, the two screw rods 4572 rotate synchronously, and the two vertical movement blocks 4573 can be driven to move away from each other in the vertical direction, so as to achieve the purpose of restraining the end of the pipe by the two support rods 456. This can effectively avoid the accidental lifting of the cut end of the pipe when the shearing assembly 3 is operating, thereby ensuring the smooth progress of the cutting operation and the neatness of the cross section.

[0028] In a further embodiment, with reference to Figure 8 As shown, the storage component 5 includes a connecting bottom plate 51 fixed on the surface of the support component 2. Two fourth support frames 52 are symmetrically installed on the connecting bottom plate 51. An installation frame 53 is fixedly installed on the two fourth support frames 52. Fifth rotating shafts 54 are rotatably installed at both ends of the installation frame 53. Transmission roller columns 56 are fixedly sleeved outside the two fifth rotating shafts 54. A transmission belt 57 for transmitting between the two is connected outside the two transmission roller columns 56. Storage grooves 571 for holding small pipe fittings are arranged at intervals outside the transmission belt 57. Two fifth driving motors 55 connected to the rear ends of the two fifth rotating shafts 54 are respectively installed on the back of the installation frame 53. When the two fifth driving motors 55 are started, they can drive the two fifth rotating shafts 54 to rotate synchronously. When the two fifth rotating shafts 54 rotate, they can drive the two transmission roller columns 56 to rotate synchronously, so as to realize the sequential and intermittent rotation of the transmission belt 57.

[0029] In this embodiment, the small pipe fittings obtained after cutting are carried by the clamping member 45, first withdrawn to the side away from the support component 2, then rotated clockwise by ninety degrees. After reaching the position, the clamping member 45 releases the small pipe fittings, so that the small pipe fittings fall into the storage grooves 571 on the transmission belt 57. The transmission belt 57 gradually delivers to realize the sequential storage of the cut pipe fittings one by one, achieving the storage purpose. After one side of the transmission belt 57 is filled with small pipe fittings, continuing to rotate the transmission belt 57 can realize the unloading purpose of the small pipe fittings stored on the transmission belt 57, facilitating the centralized unloading of small pipe fittings and facilitating workers to centrally collect the cut small pipe fittings every once in a while.
