[0045] Specifically, the existing punching equipment can place multiple automobile pipe fittings in the designated punching position in sequence through automatic feeding to realize continuous punching of the automobile pipe fittings. However, in some cases, profiled square tubes, as a kind of automobile fittings, need to be punched on one side to be assembled with the body structure. The main body of such square tube is a cuboid, one side end face is convex and has a certain curvature, and the arc surface needs to be punched. However, multiple profiled square tubes of the same specification may be uniformly conveyed from the previous process to the punching work area, and the orientations of these profiled square tubes when conveyed are not uniform and are relatively messy. In this way, the punching head 16 is difficult to accurately punch the arc surface of each profiled square tube, thereby affecting the punching efficiency.

[0046] Therefore, in order to solve the above problems, in use, the narrowest interval of the two guide plates 6 serves as a conveying channel for the profiled square tube, and the two guide plates 6 and the baffle 26 cooperate to form a rectangular channel opening. According to the size of the profiled square tube, the guide plate 6 is moved by the cylinder 7, and the threaded rod 23 is rotated by the motor 22, so that the two guide plates 6 move closer to or away from each other, and the baffle 26 rises or falls, to adjust the width of the conveying channel and the size of the rectangular channel opening, until the width of the conveying channel is greater than the length of the cross section of one profiled square tube and less than the length of the cross section of two profiled square tubes, and the distance between the lower edge of the baffle 26 and the surface of the conveying belt 5 is the height of the profiled square tube when it is placed flat.

[0047] The profiled square tube conveyed from the previous process will move to the conveying belt 5, and then drive the conveying belt 5 to move the profiled square tube. Under the action of the guide plate 6, multiple profiled square tubes are uniformly gathered into the conveying channel. Since the rectangular channel opening can only pass one flat profiled square tube at a time, multiple profiled square tubes will be arranged in the conveying channel until the profiled square tube is in contact with the groove block 46. The groove block 46 blocks the profiled square tube. Since the height of the rectangular channel opening is equivalent to the height of the profiled square tube when it is placed flat, the profiled square tube can pass through the rectangular channel opening regardless of whether the arc surface is facing down or up. When the profiled square tube is in contact with the groove block 46, the length of the profiled square tube cross-section is adjusted by rotating the bidirectional threaded rod 39 driven by the motor 8 40, adjusting the distance between the two pressure sensors 2 42, and making the distance between the two pressure sensors 2 42 equivalent to the length of the profiled square tube cross-section. Then, the detection ends of the two pressure sensors 2 42 are aligned with the two corners of the profiled square tube. Then, the slide rail plate 27 is lowered by the cylinder 2 9, and the pressure sensors 2 42 are close to the two corners of the profiled square tube. When the arc surface of the profiled square tube is facing up, the arc surface is higher than the two corners of the profiled square tube, so compared to the flat surface of the profiled square tube facing up, the pressure sensors 2 42 will detect the pressure later. Two pressure sensors 2 42 detect simultaneously and align with the two corners of the profiled square tube. Compared to using a single pressure sensor 2 42, there is no error detection when the arc surface of the profiled square tube is facing down and the profiled square tube is leaning to one side. The timing of detecting pressure by the pressure sensors 2 42 can be used to determine which side of the profiled square tube at the end of the guide plate 6 is facing up, and this information is transmitted to the controller. Then, by rotating the threaded rod 1 2 driven by the motor 1 1 and the threaded rod 2 17 driven by the motor 1 8, the horizontal and vertical positions of the finger cylinder 2 1 are adjusted, and the clamping end of the finger cylinder 2 1 is aligned with the profiled square tube at the end of the guide plate 6. Then, the profiled square tube is clamped by the finger cylinder 2 1 and removed from the conveying channel. If the arc surface of the profiled square tube is facing up, the motor 2 0 does not work. Conversely, if the arc surface of the profiled square tube is facing down, the motor 2 0 rotates the finger cylinder 2 1 by 180 degrees so that the arc surface of the profiled square tube is facing up. At this time, the finger cylinder 2 1 can move the profiled square tube to the upper surface of the workbench 3, and the punch head 1 6 is moved downward by the hydraulic cylinder 1 4 to punch the arc surface of the profiled square tube. After punching, the profiled square tube is moved to the top of the collection box 2 by the finger cylinder 2 1, the profiled square tube is released by the finger cylinder 2 1, and the profiled square tube falls into the collection box 2. Then, repeat the above operation to place multiple profiled square tubes with fixed angles on the workbench 3 and regularly punch, thereby avoiding the situation that the profiled square tubes are disordered after being conveyed by the previous process, the punch head 1 6 cannot accurately punch the arc surface of each profiled square tube, and the punching efficiency is affected.

[0048] In the present embodiment, as shown in Figures 7-13As shown, the baffle 26 is further provided with a sensing type anti-blocking and overturning integrated assembly;

[0049] The sensing type anti-blocking and overturning integrated assembly comprises a fixed plate 48 fixedly connected to one side of the upper end of the baffle 26, two ends of one side of the fixed plate 48 are fixedly connected with a sliding rod four 50, the sliding rod four 50 is slidingly connected with a cylinder three 29, a fixed block 30 is fixedly connected to the piston end of the cylinder three 29, a overturning frame 32 is rotatably arranged on one side of the fixed block 30, a positioning plate 34 is rotatably arranged on one side of the overturning frame 32, a pressure sensor one 36 is arranged on one side of the positioning plate 34, and a pressing plate 35 is slidingly connected to one side of the positioning plate 34.

[0050] A threaded rod six 49 is threadedly connected to one side of the upper end of the cylinder three 29, both ends of the threaded rod six 49 are rotatably arranged on the fixed plate 48, a motor four 28 is fixedly connected to one side of the fixed plate 48, and an output end of the motor four 28 is fixedly connected to one end of the threaded rod six 49.

[0051] A motor five 31 is fixedly connected to one side of the fixed block 30, an output end of the motor five 31 is fixedly connected to one end of the overturning frame 32, a motor six 33 is fixedly connected to one side of the overturning frame 32, an output end of the motor six 33 is fixedly connected to one side of the positioning plate 34, a threaded rod four 38 is threadedly connected to one end of the pressing plate 35, both ends of the threaded rod four 38 are rotatably arranged on the positioning plate 34, a motor seven 37 is fixedly connected to one side of the upper end of the positioning plate 34, and an output end of the motor seven 37 is fixedly connected to one end of the threaded rod four 38.

[0052] The guide plate 6 is further provided with a pushing away assembly;

[0053] The pushing away assembly comprises a push rod 43 which is inserted and slidingly connected to one side of the guide plate 6, one side of the upper end of the push rod 43 is slidingly connected with a sliding rod three 45, and one end of the sliding rod three 45 is fixedly connected to the guide plate 6.

[0054] One end of a threaded rod five 44 is rotatably arranged on the guide plate 6, and an output end of the motor nine 51 is fixedly connected to one end of the threaded rod five 44.

[0055] Specifically, in the above embodiment, although the irregular square tube can be arranged in the conveying channel under the cooperation of the guide plate 6 and the baffle 26, when the irregular square tube stands at the rectangular channel opening or is transversely arranged at the rectangular channel opening, the irregular square tube will be blocked at the rectangular channel opening, thereby affecting the smooth punching of the subsequent irregular square tube;

[0056] So, in order to solve the above problems, in use, when the special square tube converges to the conveying channel, the motor four 28 drives the threaded rod six 49 to rotate, so that the positioning plate 34 passes through the strip-shaped hole at the bottom of the baffle 26, and the initial position of the positioning plate 34 is at the bottom of the strip-shaped hole. Because the distance between the lower end edge of the baffle 26 and the conveying belt 5 is equal to the height of the special square tube when it is placed horizontally, if the special square tube at the rectangular channel opening is in a horizontal state, when the positioning plate 34 passes through the strip-shaped hole at the bottom of the baffle 26, the positioning plate 34 will not contact the special square tube. On the contrary, if the special square tube is upright, the positioning plate 34 will push the special square tube to make it fall and be in a horizontal state. Moreover, when the special square tube is upright, it can be in two states: one is that the cross section of the special square tube faces down, and the other is that the side of the special square tube faces down. Both states are higher than the bottom of the baffle 26. If the cross section of the special square tube faces down, the positioning plate 34 can push it down. If the side of the special square tube faces down, it is difficult for the end of the positioning plate 34 to push it to a horizontal state, so in order to avoid this situation, the positioning plate 34 will rise after passing through the strip-shaped hole each time. When the side of the special square tube faces down, the positioning plate 34 will be inserted into the inner cavity of the special square tube, and the edge of the special square tube will be between the positioning plate 34 and the pressing plate 35. At this time, the pressure sensor one 36 will detect the pressure value because it contacts the inner wall of the special square tube. At this time, the motor seven 37 will drive the threaded rod four 38 to rotate because the pressure sensor one 36 detects the pressure value. Then the pressing plate 35 and the positioning plate 34 cooperate to clamp the special square tube. Subsequently, the motor six 33 drives the positioning plate 34 to rotate by ninety degrees, and the clamped special square tube is turned by ninety degrees. At this time, the arc surface of the special square tube faces down or up. Then the pressing plate 35 releases the special square tube, and the motor five 31 drives the turnover frame 32 to rotate downward, so that the special square tube can slide down along the pressing plate 35 and the positioning plate 34. Then the special square tube is changed to a horizontal state, and the above operation is repeated to make the special square tube that is not horizontal and stuck at the rectangular channel opening into a horizontal state. In addition, because the pressing plate 35 needs to slide in the sliding groove on the positioning plate 34 when the pressing plate 35 and the positioning plate 34 clamp the special square tube, the sliding groove needs to have a certain length. When the pressing plate 35 and the positioning plate 34 clamp the special square tube, the sliding groove is parallel to the strip-shaped hole on the baffle 26. When the special square tube is turned by ninety degrees, the sliding groove is perpendicular to the strip-shaped hole. Therefore, if the special square tube is dropped by moving the positioning plate 34 horizontally to reset after turning, the strip-shaped hole also needs to have a certain width, which is greater than the length of the sliding groove to reset the positioning plate 34. When the strip-shaped hole is wider, the edge of the special square tube is easy to be stuck in the strip-shaped hole, causing jamming, thereby affecting normal conveying, and the width adjustment operation of the conveying channel will also be interfered to a certain extent. Therefore, it is necessary to set the strip-shaped hole to be narrower.In order to make the special-shaped square tube along the positioning plate 34 and the pressing plate 35 fall smoothly, the motor five 31 drives the turnover frame 32 to rotate downward, so that the special-shaped square tube slides off.

[0057] If the special-shaped square tube is across the rectangular channel opening, at this time, the special-shaped square tube is flat, but its two ends are in contact with the edge of the guide plate 6, and also cannot pass through the rectangular channel opening, so the two motors nine 51 are started alternately, the threaded rod five 44 is driven to rotate by the motor nine 51, and the push rod 43 on both sides moves intermittently and reciprocally, the push rod 43 pushes one side of the special-shaped square tube, so that it is deflected until the special-shaped square tube can pass through the rectangular channel opening. Thus, under the cooperation of the positioning plate 34, the pressing plate 35 and the push rod 43, the special-shaped square tube stuck in the rectangular channel opening is deflected by two ways, so that it can smoothly pass through the rectangular channel opening, ensuring the smooth progress of the subsequent punching work.

[0058] Working principle: the narrowest distance of the two guide plates 6 serves as the conveying channel of the special-shaped square tube, and the two guide plates 6 and the baffle 26 cooperate to form a rectangular channel. According to the size of the special-shaped square tube, the two guide plates 6 are moved by the cylinder 7, and the threaded rod 23 is rotated by the motor 22, so that the two guide plates 6 are close to or away from each other, the baffle 26 is raised or lowered, the width of the conveying channel and the size of the rectangular channel are adjusted, until the width of the conveying channel is greater than the length of the cross section of a special-shaped square tube and less than the length of the cross section of two special-shaped square tubes, and the distance between the lower edge of the baffle 26 and the surface of the conveying belt 5 is the height of the special-shaped square tube when it is placed flat. The special-shaped square tube conveyed from the previous process will move to the conveying belt 5, then drive the conveying belt 5 to move the special-shaped square tube, and under the action of the guide plate 6, multiple special-shaped square tubes will converge into the conveying channel. Since the rectangular channel can only pass one flat special-shaped square tube at a time, multiple special-shaped square tubes will be arranged in the conveying channel until the special-shaped square tube is in contact with the groove block 46, which will block the special-shaped square tube. Since the height of the rectangular channel is equal to the height of the special-shaped square tube when it is placed flat, the special-shaped square tube can pass through the rectangular channel regardless of whether the arc surface is facing down or up. When the special-shaped square tube is in contact with the groove block 46, the two-way threaded rod 39 is rotated by the motor 40 to adjust the distance between the two pressure sensors 42, so that the distance between the two pressure sensors 42 is equal to the length of the cross section of the special-shaped square tube. Then the detection ends of the two pressure sensors 42 are aligned with the two corners of the special-shaped square tube, and then the slide rail plate 27 is lowered by the cylinder 9 to make the pressure sensors 42 close to the two corners of the special-shaped square tube. When the arc surface of the special-shaped square tube is facing up, the arc surface is higher than the two corners of the special-shaped square tube, so compared with the flat surface of the special-shaped square tube facing up, the pressure sensor 42 will detect the pressure later, and the two pressure sensors 42 will detect the pressure at the same time and align with the two corners of the special-shaped square tube. Compared with using a single pressure sensor 42, the special-shaped square tube will not tilt to one side when the arc surface is facing down, and the detection will not be wrong. Then the timing of detecting the pressure by the pressure sensor 42 can be used to judge which side of the special-shaped square tube at the end of the guide plate 6 is facing up, and this information is transmitted to the controller. Then the horizontal and vertical positions of the finger cylinder 21 are adjusted by rotating the threaded rod 12 by the motor 11 and rotating the threaded rod 17 by the motor 18, so that the clamping end of the finger cylinder 21 is aligned with the special-shaped square tube at the end of the guide plate 6. Then the special-shaped square tube is taken out from the conveying channel by the finger cylinder 21.If the arc surface of the special-shaped square tube faces upward, the second motor 20 does not work, and vice versa, if the arc surface of the special-shaped square tube faces downward, the second motor 20 drives the finger air cylinder 21 to rotate 180 degrees, so that the arc surface of the special-shaped square tube faces upward, at this time, the finger air cylinder 21 can drive the special-shaped square tube to move to the upper surface of the workbench 3, and the punching head 16 is driven downward by the hydraulic cylinder 14 to punch the arc surface of the special-shaped square tube, after the punching is completed, the finger air cylinder 21 drives the special-shaped square tube to move above the collection box 2, the finger air cylinder 21 releases the special-shaped square tube, so that it falls into the collection box 2, and then the above operation is repeated, so that the originally disordered multiple special-shaped square tubes can be placed on the workbench 3 at a fixed angle and regularly punched, thereby avoiding the situation that the special-shaped square tubes are disordered due to the non-uniform orientation after being conveyed by the previous process, and the punching head 16 is difficult to accurately punch the arc surface of each special-shaped square tube, thereby affecting the punching efficiency. When the special-shaped square tubes converge in the conveying channel, the fourth motor 28 drives the threaded rod six 49 to rotate, so that the positioning plate 34 passes through the strip-shaped hole at the bottom of the baffle 26, and the initial position of the positioning plate 34 is at the bottom of the strip-shaped hole. Because the distance between the lower end edge of the baffle 26 and the conveying belt 5 is equal to the height of the special-shaped square tube when it is placed horizontally, if the special-shaped square tube at the rectangular channel opening is in a horizontal state, when the positioning plate 34 passes through the strip-shaped hole at the bottom of the baffle 26, the positioning plate 34 will not contact the special-shaped square tube, and vice versa, if the special-shaped square tube is upright, the positioning plate 34 will push the special-shaped square tube to make it fall and be in a horizontal state. Moreover, when the special-shaped square tube is upright, it can be in two states, one is that the cross section of the special-shaped square tube faces downward, and the other is that the side surface of the special-shaped square tube faces downward, both of which are higher than the bottom of the baffle 26, if the cross section of the special-shaped square tube faces downward, the positioning plate 34 can push it down, if the side surface of the special-shaped square tube faces downward, the end of the positioning plate 34 is difficult to push it to a horizontal state, therefore, in order to avoid this situation, the positioning plate 34 will rise after passing through the strip-shaped hole each time. When the side surface of the special-shaped square tube faces downward, the positioning plate 34 will be inserted into the inner cavity of the special-shaped square tube, and the edge of the special-shaped square tube is between the positioning plate 34 and the pressing plate 35, at this time, the pressure sensor one 36 will detect the pressure value due to the contact with the inner wall of the special-shaped square tube, at this time, the seventh motor 37 will drive the threaded rod four 38 to rotate due to the detection of the pressure value by the pressure sensor one 36, and the special-shaped square tube is clamped by the cooperation of the pressing plate 35 and the positioning plate 34, then the sixth motor 33 drives the positioning plate 34 to rotate 90 degrees, and the clamped special-shaped square tube is turned over 90 degrees, at this time, the arc surface of the special-shaped square tube faces downward or upward, then the pressing plate 35 releases the special-shaped square tube, the fifth motor 31 drives the turnover frame 32 to rotate, so that the special-shaped square tube slides off the positioning plate 34, and the special-shaped square tube is changed to a horizontal state, and the above operation is repeated, so that the special-shaped square tubes that are not placed horizontally and are stuck at the rectangular channel opening are all changed to a horizontal state.If the special square tube is horizontally placed at the rectangular passage opening, the special square tube cannot pass through the rectangular passage opening, although it is horizontally placed, because its two ends are in contact with the edges of the guide plate 6. Therefore, the motors 51 on both sides are started in turn, the threaded rods 44 are rotated by the motors 51, and the push rods 43 on both sides are intermittently reciprocated. The push rods 43 push one side of the special square tube to deflect it until the special square tube can pass through the rectangular passage opening. Thus, the special square tube stuck in the rectangular passage opening can be deflected by the two ways to pass through the rectangular passage opening under the cooperation of the positioning plate 34, the pressing plate 35 and the push rod 43, so that the subsequent punching work can be smoothly carried out.
