[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 As shown, a cutting device for automobile parts production includes a base plate 1, a cutting portion is provided at one end of the top thereof, a material guide plate 4 is also provided, a first material storage box 13 is provided at the bottom of the material guide plate 4, a through hole 101 is provided through the base plate 1, a material feeding assembly 5 is provided in the through hole 101, a baffle 7 fixed on the base plate 1 is provided on one side of the material feeding assembly 5, and a material storage table 8 for stacking pipe fittings is provided on the other side; the material feeding assembly 5 includes an annular plate 501 and a limiting slideway 502 fixed on its outer periphery, at least three groups of mounting blocks 503 are slidably connected on the limiting slideway 502, and adjacent mounting blocks 503 are connected by connecting ropes 506; along the conveying direction of the annular plate 501, the head end mounting block 503 is provided with a lap ring The push plate 504 of the annular plate 501 is provided with a driving component 12 on the baffle plate 7 for driving the push plate 504 to move horizontally along the annular plate 501 to push the workpiece to the cutting part. The end mounting block 503 is provided with a tail plate 505 overlapping the annular plate 501, and the middle mounting block 503 is provided with a blocking component 6; a sliding plate 901 is slidably provided at the bottom of the base plate 1 located at the lower side of the cutting part, which is connected to the tail plate 505 by a bolt rope 904, and an energy storage component 9 is also provided at the bottom of the base plate 1. The energy storage component 9 is elastically connected to the sliding plate 901. The movement of the sliding plate 901 causes the energy storage component 9 to elastically store energy, keeping the connecting rope 506 and the bolt rope 904 taut. The connecting rope 506 is a non-elastic rope to ensure the synchronous movement of the push plate 504 and the tail plate 505; When the push plate 504 is driven to move out of the storage table 8, the pipe fittings roll down to the annular plate 501 by their own weight, and the push plate 504 pushes the pipe fittings to the cutting part to complete equidistant cutting, and the cut pieces are discharged into the first storage box 13 through the guide plate 4; during this period, the blocking component 6 abuts against the subsequent pipe fittings of the storage table 8 to prevent discharge; after the push plate 504 reaches the cutting end, the tail plate 505 is linked to the sliding plate 901 to move out, and the remaining pipe sections of the cutting part are automatically discharged into the second storage box 14 through the through hole 101.

[0022] In this embodiment, the pipe fittings in the material storage platform 8 roll down to the annular plate 501 of the feeding component 5 under the action of their own weight, and the driving component 12 pushes the push plate 504 to move horizontally along the limiting slide 502, pushing the pipe fittings to the cutting part for equidistant cutting; in this process, the blocking component 6 of the middle mounting block 503 abuts against the subsequent pipe fittings in the material storage platform 8 to prevent them from rolling down and interfering with the current process; the qualified workpieces after cutting slide out through the guide plate 4 for unloading; when the push plate 504 moves to the extreme position of the cutting end, the tail plate 505 of the end mounting block 503 slides through the bolt rope 904 to link the bottom sliding plate 901 to slide, so that the energy storage component 9 stretches and stores energy, and when the push plate 504 moves to the extreme position of the cutting end, the through hole 101 at the bottom of the cutting part is exposed, and the remaining cut pipe section automatically falls through the through hole 101 to complete the material separation; then, the driving component 12 drives the push plate 504 and the tail plate 505 to return to the initial position, and the next pipe fitting automatically rolls down to the annular plate 501, entering a new round of cutting cycle; The device realizes the full process automation of automatic loading, equidistant pushing, cutting and sorting of pipes through the linkage design of the feeding component 5 and the driving component 12. The linkage of the push plate 504, the tail plate 505 and the sliding plate 901 and the division of labor between the guide plate 4 and the through hole 101 can separate qualified parts from residual tailings, thereby avoiding manual sorting errors.

[0023] Preferably, the blocking assembly 6 includes an elastic member arranged on the mounting block 503, a shaft 604 is fixed to the free end of the elastic member, and a roller 605 is rotatably sleeved on the shaft 604; when the driving assembly 12 drives the push plate 504, the roller 605 maintains contact with the workpiece through the elastic member; The elastic member includes a square rod 601 that slides through the mounting block 503. An end plate 602 is provided at one end of the square rod 601 close to the baffle 7. A first spring 603 sleeved on the square rod 601 is connected between the end plate 602 and the mounting block 503. The other end of the square rod 601 is connected to the shaft rod 604. A distance meter 606 for measuring the distance between the shaft 604 and the baffle 7 in real time is arranged on the top of the shaft 604 , and the distance meter 606 is connected to an external control system.

[0024] In this embodiment, when the driving component 12 pushes the push plate 504 to move, the roller 605 of the blocking component 6 contacts the surface of the subsequent pipe on the storage platform 8 through the elastic member; specifically, the subsequent pipe presses down the roller 605 to drive the shaft 604 to move toward the baffle 7, and the square rod 601 slides accordingly and compresses the first spring 603 sleeved thereon; the elastic force of the first spring 603 makes the roller 605 always close to the surface of the pipe, preventing the subsequent pipe from rolling down and interfering with the current feeding, and avoiding damage to the workpiece caused by rigid contact; at the same time, the rangefinder 606 on the top of the shaft 604 detects the distance change between the shaft 604 and the baffle 7 in real time, and feeds back the data to the external control system. The rangefinder 606 monitors the displacement of the shaft 604 and feeds back the straightness data of the pipe in real time. If the pipe is bent or deformed, the distance measurement value will fluctuate abnormally, and the control system can issue an early warning or adjust the cutting parameters accordingly to ensure processing accuracy.

At this time, the energy storage component 9 releases the elastic potential energy, and the linkage sliding plate 901 and the tail plate 505 are synchronously reset to complete a cutting cycle.

At this time, the second spring 903 between the sliding plate 901 and the fixed plate 902 is stretched to store energy, and the remaining pipe section after cutting is automatically unloaded through the through hole 101 of the base plate 1; then, when the driving component 12 drives the push plate 504 to reset, the second spring 903 releases the elastic potential energy, driving the tail plate 505 and the sliding plate 901 to return to the initial position.

The cutting disc 205 corresponds to the cutting groove 303, and the servo motor 204 can drive the cutting disc 205 to rotate to cut the workpiece; In this embodiment, when the pipe is first conveyed to the annular plate 501, a positioning calibration process is performed to ensure the accuracy of the first section of cutting. Specifically, the hydraulic rod 304 is first started to drive the abutment block 302 to move toward the inclined base 201 and abut, and the synchronous drive component 12 drives the push plate 504 to push the pipe, so that the end of the pipe is completely fitted with the abutment block 302, and the precise calibration of the initial position of the pipe is completed. After the calibration is completed, the hydraulic rod 304 retracts to drive the abutment block 302 to reset; the first movement of the push plate 504 after the calibration is completed will push the pipe to the designated cutting position according to the preset cutting length and the sum of the distances between the abutment block 302 and the cutting groove 303, and the subsequent movements will be based on The cutting length standard moves; when the pipe is pushed to the cutting part by the push plate 504, the hydraulic rod 304 of the fixing assembly 3 drives the abutment block 302 to slide in the fixing base 301 to clamp and fix the pipe; then the electric push rod 202 of the cutting device 2 is started to push the sliding seat 203 to slide along the top surface of the inclined base 201 toward the pipe, and at the same time, the servo motor 204 drives the cutting disc 205 to rotate at high speed to complete the cutting of the workpiece, and the cut pipe is automatically unloaded through the guide plate 4; after the cutting is completed, the electric push rod 202 retracts to drive the sliding seat 203 to reset, and the hydraulic rod 304 simultaneously releases the abutment block 302 to release the fixation of the workpiece, waiting for the push plate 504 to push the pipe to move again.
