Description

Technical Field

[0001] The invention relates to the technical field of harrow blade production, in particular to a full-automatic stamping and punching production line for harrow blades. Background Art

[0002] In modern agricultural machinery, harrow blades are key tillage components, and their quality and production efficiency have a direct impact on the overall performance and effectiveness of agricultural machinery. Currently, the stamping and punching processes in harrow blade manufacturing are mostly performed manually or using semi-automatic equipment. Manual operation not only results in low production efficiency and is difficult to meet the needs of large-scale production, but also, due to differences in operator skill levels and work habits, it is difficult to ensure the dimensional accuracy and quality stability of harrow blades, resulting in high scrap rates.

[0003] While existing semi-automatic equipment has improved production efficiency to a certain extent, it still requires manual operations such as loading and unloading, and positioning. For example, the utility model patent for a rake blade stamping and forming device, with publication number CN215697131U, addresses the issue of preventing clothing from getting caught on workers and potentially causing falls. However, the device has a low level of automation, resulting in high labor intensity and poor production process continuity. Furthermore, both manual and semi-automatic equipment pose safety risks during production, making operator injuries easily caused by misoperation.

[0004] With the rapid development of agricultural mechanization, the market demand for harrow blades continues to increase, and at the same time, higher requirements are being placed on the quality and production efficiency of harrow blades. Traditional production methods are no longer able to meet the needs of industry development. A new production line is needed that can achieve automated and continuous production of harrow blade punching, improve production efficiency and product quality, and reduce labor intensity and production costs.

DETAILED DESCRIPTION

[0038] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0039] like Figures 1-18As shown, the present invention provides a fully automatic stamping and punching production line for rake blades, including a punching machine 17, wherein the punching machine 17 is provided with a feed port and a discharge port, and a raw material plate conveying platform is provided at the feed port, and the raw material plate conveying platform includes a feed trolley 11, and the feed trolley 11 is provided with a feed track 15, and the feed trolley 11 is also provided with a pusher seat 14 that can move back and forth; a material plate trolley 1 is provided at the front end of the feed trolley 11, and a plurality of raw material plates are placed on the material plate trolley 1, and a loading mechanism is provided at the upper end of the feed trolley 11, and the loading mechanism includes a movable rack 6, and a plurality of suction cups 10 for adsorbing and fixing the raw material plates are provided at the lower end of the rack 6, and when the rack 6 moves, the raw material plates can be put onto the feed trolley 11 When the pushing seat 14 moves, the raw material plate can be pushed into the punching machine 17; a unloading device is provided at the discharge port, and the unloading device includes a unloading frame 21, and the unloading frame 21 is provided with a clamping mechanism, and the clamping mechanism includes a movable driving seat 23, and the driving seat 23 is equipped with a rotatable chuck 25, and the chuck 25 is provided with a clamp that can be opened and closed. When the clamp is closed, the residual material of the raw material plate after punching can be clamped and fixed. When the driving seat 23 moves to one side, the chuck 25, the clamp and the residual material can be driven to move to one side synchronously. When the driving seat 23 moves to one side to a specified position, the chuck 25 can rotate and the clamp can be opened to rotate the residual material and then put it into the specified position.

[0040] like Figures 1-10 As shown, a lifting platform 2 is provided on the material plate vehicle 1, and the raw material plate is placed on the lifting platform 2. Through the provided loading mechanism, that is, the movable rack 6, the suction cup 10, etc., when the rack 6 and the suction cup 10 move downward to contact with the raw material plate, the suction cup 10 can adsorb and fix the raw material plate. The suction cup 10 is a prior art and will not be described in detail. Then, by controlling the rack 6 to move upward and backward, the raw material plate can be transported to the feed vehicle 11, that is, the raw material plate is placed on the feed track 15. The feed track 15 is installed and shaped as shown in FIG. Figure 5 or Figure 6 , a plurality of rollers are provided on the feeding track 15, which can reduce the friction when the pushing seat 14 pushes the raw material plate to move. By setting the pushing seat 14 that can move back and forth, the raw material plate can be pushed to the punching machine 17; the punching machine 17 is used to punch the raw material plate, so that the raw material plate is punched out with multiple rake pieces; Figure 7As shown, the punching machine 17 is provided with a punching table, a feed port is provided on the left side of the punching table, a discharge port is provided on the right side, and a discharge port is provided in the middle of the punching table. When the raw material plate is pushed onto the punching table, when the punching machine 17 is working, rake pieces can be punched out on the raw material plate, and the rake pieces are discharged from the discharge port under the action of gravity. A rake piece conveying platform is also provided at the discharge port, and a feed track 15 and a pushing seat 14 are also provided on the rake piece conveying platform. The rake piece conveying platform has the same structure as the raw material plate conveying platform. The rake piece falls onto the rake piece conveying platform from the discharge port, and then can be pushed into the punching machine 18 by the pushing of the pushing seat 14. The punching machine 18 can perform rake cutting on the rake piece when it is working. The punching operation, the punching machine 17 and the punching machine 18 belong to the existing technology and are not described in detail. Under the drive of the pusher 14, the remaining raw material sheet after punching can be moved out from the discharge port and moved to the discharge rack 21. Through the provided clamping mechanism, chuck 25, clamp, etc., when the remaining raw material sheet moves into the clamp, the clamp can be closed to clamp and fix the remaining raw material sheet. At this time, the pusher 14 moves, and the drive seat 23 can keep moving synchronously with the pusher 14. When all the raw material sheets are punched, the drive seat 23 continues to move to one side, which can drive the remaining raw material sheet out of the punching machine 17 and completely drive into the discharge rack 21. When the drive seat 23 continues to move to one side, When the machine reaches the designated position, the chuck 25 and the clamp can be rotated, that is, the corresponding residual material of the raw material plate can be rotated and tilted during rotation, and the clamp can be opened to allow the residual material to fall into the designated position; the production line realizes automatic loading and unloading and punching, and does not require frequent manual intervention in material handling and punching operations. Compared with traditional manual or semi-automatic production lines, it greatly shortens the production cycle. The automatic loading and unloading function replaces repetitive labor such as manual handling, loading and unloading, and reduces the dependence on a large number of general workers in the production process; the automatic punching link does not require manual operation of the stamping equipment, which reduces labor cost expenditure. At the same time, reducing manual operation also reduces the training cost caused by personnel turnover; automatic punching The cutting process is operated by a control system and runs strictly according to the preset program. It can accurately control the position, size and depth of stamping and punching, avoiding errors and unstable factors that may occur in manual operation, making the quality of the produced rake blades more stable, greatly improving product consistency, reducing scrap and defective rates, and enhancing the competitiveness of the company's products; automatic loading and unloading and automatic punching and cutting reduce direct contact between workers and stamping equipment, and reduce the risk of mechanical injuries caused by operational errors, fatigue, etc. during the loading and unloading and stamping processes, effectively protecting the personal safety of workers, reducing the probability of safety accidents in the company, and reducing the economic losses and negative impacts caused by safety accidents.

[0041] The loading mechanism includes a retractable driving arm 3, on which a lifting arm 4 that can move up and down is installed. A rack 6 is installed at the lower end of the lifting arm 4. A plurality of cross bars are provided at the lower end of the rack 6, and square seats 7 are provided at both ends of the cross bars. The suction cups 10 are all installed on the corresponding square seats 7.

[0042] like Figure 2-Figure 4 As shown, the driving arm 3 can be extended and retracted forward and backward, that is, it can drive the lifting arm 4, the frame 6, the suction cup 10, etc. to move forward and backward; the lifting arm 4 slides up and down and is connected to the driving arm 3, and the driving arm 3 is also provided with a driving rod 5. When the driving rod 5 is extended and retracted, it can drive the lifting arm 4 to move up and down, that is, drive the frame 6, the suction cup 10, etc. to move up and down. The driving arm 3 and the driving rod 5 both belong to the existing technology and are not repeated here; the frame 6 is fixedly connected to the lower end of the lifting arm 4, the cross bar is fixedly connected to the frame 6, and the square seat 7 is fixedly connected to the cross bar. By setting the cross bar and the square seat 7, the suction cup 10 can be evenly installed.

[0043] A sleeve 8 is provided on one side of the square seat 7, and a sleeve rod 9 is slidably connected to the inner wall of the sleeve 8. The suction cup 10 is fixed to the lower end of the sleeve rod 9. The upper and lower ends of the outer surface of the sleeve rod 9 are sleeved with fault-tolerant springs 39, and the upper end surface of the sleeve rod 9 is also fixed with an anti-drop cap.

[0044] like Figure 4-Figure 6 As shown, the sleeve 8 is fixed on the square seat 7, and the sleeve rod 9 can be slid up and down and connected to the inner wall of the sleeve 8. The anti-slip cap can prevent the sleeve rod 9 from being separated from the sleeve 8, and the anti-slip cap can prevent the fault-tolerant spring 39 from falling off. The fault-tolerant spring 39 is set, and the sleeve rod 9 and the suction cup 10 can have a range of movement up and down. Since the upper end surface of the raw material plate usually has uneven areas, with the cooperation of the sleeve rod 9, the suction cup 10 and the fault-tolerant spring 39, when the rack 6 moves downward, each suction cup 10 can contact the upper end surface of the raw material plate, and the suction cup 10 can more effectively adsorb and fix the raw material plate during adsorption.

[0045] A first motor 12 is provided in the feed trolley 11, and a threaded rod 13 is fixedly connected to the output end of the first motor 12. The pusher seat 14 is threadedly connected to the outer surface of the threaded rod 13, and the pusher seat 14 is slidably connected to the inner wall of the feed trolley 11. Guide plates 16 are also provided on both sides of the feed trolley 11.

[0046] like Figure 5-Figure 6 As shown, the first motor 12 is fixed to the inner wall of the feed cart 11. When the first motor 12 is started, it can drive the threaded rod 13 to rotate. The motor is existing technology and will not be described in detail. The pushing seat 14 can slide left and right on the inner wall of the feed cart 11. The inner wall of the pushing seat 14 is provided with a threaded hole that matches the threaded rod 13, which is equivalent to the pushing seat 14 being threadedly connected to the outer surface of the threaded rod 13. When the threaded rod 13 rotates, the threaded rod 13 is engaged with the threaded hole, which can drive the pushing seat 14 to move left or right, that is, the pushing seat 14 moves back and forth left and right. When the pushing seat 14 moves, it can push the raw material plate to move, that is, push the raw material plate into the punching machine 17. The guide plate 16 is set, and the raw material plate can be accurately pushed into the punching machine 17.

[0047] The unloading device also includes a drive box 19, the inner wall of the drive box 19 is provided with a movable drive plate 20, a drive seat 23 is installed at the lower end of the drive plate 20, the inner wall of the drive seat 23 is provided with a rotatable drive shaft 24, and the chuck 25 is fixed on the drive shaft 24. The clamp includes a first clamp seat 26 and a second clamp seat 27, and the first clamp seat 26 and the second clamp seat 27 are movably installed on the chuck 25.

[0048] like Figures 8-10 As shown, the inner wall of the drive box 19 is provided with a rotatable screw, and a nut is sleeved on the outer surface of the screw. The drive plate 20 is fixed to the nut. When the screw rotates, it can drive the nut and the drive plate 20 to move; the chuck 25 is used to install the clamp. By setting a rotatable drive shaft 24, when the drive shaft 24 rotates, the chuck 25 and the clamp can be driven to rotate; under the mutual cooperation of the first clamp seat 26 and the second clamp seat 27, when the first clamp seat 26 and the second clamp seat 27 move, the clamp can be controlled to open or close.

[0049] A spring seat 28 is fixedly connected to the chuck 25, and the first clamp seat 26 is slidably connected to the chuck 25. A first spring 29 that cooperates with the first clamp seat 26 is provided on the spring seat 28. Two baffle boxes 34 are fixedly connected to the chuck 25. The inner walls of the baffle boxes 34 are slidably connected with wedge-shaped blocks 35. The inner walls of the baffle boxes 34 are also provided with second springs 36 that cooperate with the wedge-shaped blocks 35. First sliding pins 37 are fixedly connected to both sides of the first clamp seat 26.

[0050] like Figures 9-13 As shown, the first clamping seat 26 can be slidably connected to the clamping plate 25 up and down, and the spring seat 28 supports and fixes the first spring 29. The upper end of the first spring 29 is fixed to the spring seat 28, and the lower end is fixed to the first clamping seat 26. The first spring 29 always has a downward thrust on the first clamping seat 26, so that the first clamping seat 26 has a downward clamping force under normal conditions. One or more first springs 29 can be provided; the block box 34, the second spring 36, the wedge-shaped block 35, and the first sliding pin 37 are installed and shaped as shown in FIG. Figure 12 and Figure 13When the first slide pin 37 is at the upper end of the wedge stopper 35, the wedge stopper 35 can block the first slide pin 37 under the obstruction of the straight surface of the wedge stopper 35, that is, the first slide pin 37 and the first clamping seat 26 are at the uppermost position, and the clamp is in the open state. When the wedge stopper 35 moves to the right and enters the interior of the block box 34, the wedge stopper 35 can be disengaged from the first slide pin 37. At this time, the first slide pin 37 and the first clamping seat 26 can be extended to the left under the elastic force of the first spring 29. The first clamping seat 26 and the first sliding pin 37 are moved upward to reset, and the first sliding pin 37 can meet the inclined surface of the wedge-shaped stopper 35. Under the meshing of the first sliding pin 37 and the inclined surface, the wedge-shaped stopper 35 can be moved to the right into the inner wall of the stop box 34 and compress the second spring 36. When the first sliding pin 37 moves upward and disengages from the wedge-shaped stopper 35, the wedge-shaped stopper 35 can be ejected to the left outside the stop box 34 under the elastic force of the second spring 36. At this time, the wedge-shaped stopper 35 can block the first sliding pin 37 again. Under the cooperation of the inclined surface and the first sliding pin 37, the first clamping seat 26 and the first sliding pin 37 can be moved upward from the bottom to the upper end position to reset. At this time, the clamp is in the open state.

[0051] The chuck 25 is provided with a movable trigger plate 30, and a U-shaped seat 33 is slidably connected to the baffle box 34. A first connecting rod 32 that cooperates with the U-shaped seat 33 is provided on both sides of the trigger plate 30, and a short pin 63 is provided on both sides of the wedge-shaped block 35. An oblique key groove 38 that cooperates with the short pin 63 is opened on both sides of the U-shaped seat 33.

[0052] like Figure 12-13As shown, the middle part of the chuck 25 is fixedly connected to the limited telescopic rod 31, and the trigger plate 30 is fixedly connected to the telescopic end of the limited telescopic rod 31. Under the limit of the limited telescopic rod 31, the trigger plate 30 can only move left and right on the chuck 25; one end of the first connecting rod 32 is hinged on the trigger plate 30, and the other end of the first connecting rod 32 is hinged on the U-shaped seat 33. The U-shaped seat 33 can be slidably connected to the end surfaces of both sides of the block box 34. Under the engagement of the oblique key groove 38 and the short pin 63, when the U-shaped seat 33 moves upward, the short pin 63 and the wedge-shaped stopper 35 can be driven to move to the right, that is, the wedge-shaped stopper 35 enters the inner wall of the block box 34; similarly, when the U-shaped seat 33 moves downward, the first sliding pin 37 and the wedge-shaped stopper 35 can move left and right. When the raw material plate moves to the right after punching, it can contact the trigger plate 30. When the raw material plate continues to move to the right, it can squeeze the trigger plate 30 to move to the right. When the trigger plate 30 moves to the right, under the hinge of the first connecting rod 32 and the U-shaped seat 33, it can drive the U-shaped seat 33 to move upward, that is, the corresponding first sliding pin 37 and wedge-shaped stopper 35 move to the right. When the wedge-shaped stopper 35 moves to the right and disengages from the first sliding pin 37, the first clamping seat 26 moves downward under the elastic force of the first spring 29. The first clamping seat 26 can squeeze and fix the remaining raw material plate. At this time, the drive plate 20, the drive seat 23 and the pushing seat 14 are controlled to keep moving synchronously, which can control the precise movement of the raw material plate and improve the punching accuracy.

[0053] The driving seat 23 is slidably connected to the lower end of the driving plate 20, and a first movable pin 51 is provided on the driving seat 23. A first track frame 52 is fixedly connected to the end surface of one side of the driving box 19, and the first track frame 52 is provided with a first long transverse groove 53, a first short oblique groove 54 and a short transverse groove 55 that cooperate with the first movable pin 51; a spur gear 57 is fixedly connected to the outer surface of the driving shaft 24, and a spur rack 56 that is slidably connected to the driving seat 23 is meshed on the outer surface of the spur gear 57, and a second movable pin 58 is fixedly connected to the spur rack 56. A second track frame 59 is also fixedly connected to the end surface of one side of the driving box 19, and a second long transverse groove 60 and a second short oblique groove 61 that cooperate with the second movable pin 58 are provided on the second track frame 59.

[0054] like Figure 16-Figure 18As shown, the driving seat 23 is connected to the lower end of the driving plate 20 in a sliding manner forward and backward. When the driving plate 20 moves left and right, it can drive the driving seat 23 to move left and right, and the driving seat 23 can slide back and forth at the lower end of the driving plate 20; an L-shaped connecting rod 50 is fixed to the upper end of the driving seat 23, and the first movable pin 51 is fixed to the L-shaped connecting rod 50, which is equivalent to the first movable pin 51 being fixed to the driving seat 23, that is, when the driving seat 23 moves left and right, it can drive the first movable pin 51 to move left and right, and when the first movable pin 51 moves back and forth, it can The drive seat 23 can be moved back and forth; the drive shaft 24 is rotatably connected to the inner wall of the drive seat 23, and the spur rack 56 can slide back and forth on the inner wall of the drive seat 23. The second movable pin 58 is fixed to the spur rack 56 through the connecting rod. When the second movable pin 58 and the spur rack 56 move back and forth, the spur rack 56 is engaged with the spur gear 57, which can drive the spur gear 57, the drive shaft 24, and the chuck 25 to rotate, that is, the clamp rotates; the installation and shape of the first track frame 52, the first movable pin 51, the second track frame 59, and the second movable pin 58 are as shown in the figure. Figure 18As shown, the first long transverse groove 53 and the second transverse oblique groove 60 are both arranged parallel to the unloading rack 21. When the first movable pin 51 is engaged with the first long transverse groove 53, the driving seat 23 can always be in the middle position of the unloading rack 21 and move left and right when following the driving plate 20 to move back and forth. When the second movable pin 58 is engaged with the second transverse oblique groove 60, the straight rack 56 is in a specified position, that is, at this time the straight rack 56 can only move left and right with the driving seat 23 and will not move forward and backward. Since the driving seat 23 will not move forward and backward under the engagement of the first movable pin 51 and the first long transverse groove 53, the straight rack 56 and the straight rack The gear 57 will maintain a relatively stationary state and move left and right without causing the drive shaft 24 to rotate, that is, the corresponding clamp will maintain a vertical state; the first short oblique groove 54 is arranged in parallel with the second short oblique groove 61, and the second short oblique groove 61 is longer than the first short oblique groove 54. When the drive seat 23 moves to the right to the specified position, even if the first movable pin 51 enters the inner wall of the first short oblique groove 54 and the second movable pin 58 enters the inner wall of the second short oblique groove 61, when the drive seat 23 continues to move to the right, the engagement of the first movable pin 51 and the first short oblique groove 54 can make the drive seat 23, the clamp, etc. move backward synchronously. Under the meshing of the second live pin 58 and the second short oblique groove 61, the spur rack 56 can keep moving backward synchronously with the drive seat 23 and the spur gear 57, that is, the clamp and the chuck 25 move synchronously to the left and move backward at the same time. When the drive seat 23 moves to the right so that the first live pin 51 enters the inner wall of the short transverse groove 55, the second live pin 58 continues to move on the inner wall of the second short oblique groove 61. When the drive seat 23 continues to move to the right, under the meshing of the first live pin 51 and the short transverse groove 55, the corresponding drive seat 23 no longer moves backward, but only moves horizontally to the right. When the drive seat 23 is engaged with the groove 55, the spur rack 56 can follow the drive seat 23 and move rightward and backward. When the spur rack 56 moves backward, it can rotate with the spur gear 57, the drive shaft 24, the chuck 25, the clamp, etc.; that is, the clamp can rotate when the drive seat 23 moves to the specified position. When the drive seat 23 moves to the left and resets, the clamp can be flipped over and reset in the opposite direction under the mutual cooperation of the first movable pin 51 and the first track frame 52, and the second movable pin 58 and the second track frame 59, that is, it rotates to a vertical state and then moves to the left to reset.

[0055] The second clamping seat 27 is slidably connected to the clamping plate 25. A third sliding pin 47 is fixed to one side of the second clamping seat 27. A fixed plate 46 is fixed to one end surface of the driving seat 23. The fixed plate 46 is provided with an arc groove 48 and a reducing groove 49 that cooperate with the third sliding pin 47.

[0056] like Figure 11 and Figure 16 As shown, the second clamping seat 27 can be slidably connected to the clamping plate 25 up and down, and the installation and shape of the third sliding pin 47 and the fixed plate 46 are as shown. Figure 16As shown, the drive shaft 24 passes through the fixed plate 46 and is rotatably connected to the inner wall of the fixed plate 46. The fixed plate 46 is fixedly connected to the drive seat 23, so that the fixed plate 46 cannot rotate. Under the cooperation of the third sliding pin 47, the arc groove 48 and the reducing groove 49, when the drive shaft 24 and the chuck 25 rotate, the second clamping seat 27 and the third sliding pin 47 can be driven to move synchronously in a circular motion. When the third sliding pin 47 moves in a circular motion on the inner wall of the arc groove 48, the third sliding pin 47 and the second clamping seat 27 will not move downward. When the third sliding pin 47 enters the inner wall of the reducing groove 49, the drive shaft 24 and the chuck 25 are in a state of rotation. 5 continues to rotate, and the engagement of the third sliding pin 47 with the reducing groove 49 enables the second clamping seat 27 to move downward while moving in a circular motion. When the second clamping seat 27 moves downward, it can move away from the first clamping seat 26, and the clamp is now in an open state. When the driving shaft 24 and the clamping plate 25 are reversed and reset, the engagement of the third sliding pin 47 with the reducing groove 49 and the arc groove 48 enables the corresponding second clamping seat 27 to move upward while moving in a circular motion and reset to the initial position. That is, after the driving seat 23 and the clamp move to the rightmost end, the clamp can rotate again and can be opened again after rotating to a specified angle.

[0057] A long box 40 is provided at the upper end of the first clamping seat 26, and the inner walls at both ends of the long box 40 are slidably connected to the second sliding pin 41. The inner walls at both ends of the long box 40 are also provided with a third spring 42 that cooperates with the second sliding pin 41. A support frame 62 is fixed to the drive box 19, and the lower end of the support frame 62 is provided with two double-sided wedge blocks 43 that cooperate with the second sliding pin 41. One end of the double-sided wedge blocks 43 is provided with a first inclined surface 44, and the other end of the double-sided wedge blocks 43 is provided with a second inclined surface 45.

[0058] like Figure 14 and Figure 15 As shown, the upper end of the first clamping seat 26 is fixed with a support column, and the long box 40 is fixed on the support column, which is equivalent to the long box 40 being fixed on the first clamping seat 26. The second sliding pin 41 can slide back and forth on the inner wall of the long box 40. The third spring 42 always has an outward driving force on the second sliding pin 41, so that the second sliding pin 41 is in an extended state under normal conditions; the support frame 62 supports and fixes the double-sided wedge block 43. The shape of the double-sided wedge block 43 is as shown in FIG. Figure 15As shown, the left end of the double-sided wedge block 43 is provided with a first inclined surface 44 and the right end is provided with a second inclined surface 45. When the driving seat 23, the first clamping seat 26, the long box 40, the second sliding pin 41, etc. move from left to right, the second sliding pin 41 can meet the first inclined surface 44. When the second sliding pin 41 meets and engages with the first inclined surface 44, the two second sliding pins 41 can move inward under the contact and engagement of the first inclined surface 44 to compress the third spring 42. When the driving seat 23, the second sliding pin 41, etc. move to the right and disengage from the double-sided wedge block 43, the second sliding pin 41 will extend and reset again under the elastic force of the third spring 42; when the driving seat 23, the second sliding pin 41, etc. move from right to left, the second sliding pin 41 will meet the second inclined surface 45 of the double-sided wedge block 43. When the sliding pin 41 is in contact with the second inclined surface 45, the second sliding pin 41, the long box 40, the first clamping seat 26, the first sliding pin 37, etc. can move upward. When the first clamping seat 26 moves upward to the top position, the first sliding pin 37 can move to the upper end position of the wedge-shaped stopper 35, that is, the wedge-shaped stopper 35 can block the first clamping seat 26, so that the wedge-shaped stopper 35 and the first clamping seat 26 are in the uppermost position, and the clamp is in an open state. Under the mutual cooperation of the unloading device and the clamping mechanism, when the remaining raw material plate moves to the specified position to the right, that is, when the raw material plate contacts and squeezes the trigger plate 30 to move to the right, the wedge-shaped stopper 35 will move to the right. After the wedge-shaped stopper 35 moves to the right and disengages from the first sliding pin 37, the first clamping seat 26 is in the first spring state. 29, moves downward under the elastic force of the first clamping seat 26, and the first clamping seat 26 can squeeze and clamp the raw material plate. At this time, the clamp is in a closed state to clamp and fix the raw material plate. By controlling the driving seat 23 and the pushing seat 14 to move synchronously to the right, the raw material plate can be stably driven to move to the right, so that the raw material plate is accurately moved to the specified position, thereby improving the punching accuracy; when the driving seat 23 moves to the right, under the engagement of the first movable pin 51 and the first long horizontal groove 53, the driving seat 23 can keep moving to the right parallel to the unloading rack 21, that is, the driving seat 23, the clamp, etc. will not move forward or backward, and under the engagement of the second movable pin 58 and the second horizontal oblique groove 60, the spur rack 56 will keep moving to the right synchronously with the spur gear 57, that is, the corresponding chuck 25, clamp, etc. will not rotate. When the driving seat 23 and the clamps move to the right and make the first movable pin 51 enter the inner wall of the first short inclined groove 54 and the second movable pin 58 enter the inner wall of the second short inclined groove 61, the remaining raw material sheet is separated from the punching machine 17 and completely driven into the unloading rack 21. When the driving seat 23 continues to move to the right, the first movable pin 51 is engaged with the first short inclined groove 54 and the second movable pin 58 is engaged with the second short inclined groove 61, which can make the driving seat 23, the spur rack 56, the spur gear 57, the clamps, etc. keep moving to the right and move backward synchronously. When the clamp moves backward,It can also drive the raw material plate to move backward. When the raw material plate moves backward, the front end of the raw material plate will be out of contact with the discharge rack 21. When the driving seat 23 continues to move to the right until the first movable pin 51 enters the inner wall of the short transverse groove 55 and the second movable pin 58 continues to move to the right on the inner wall of the second inclined groove, the driving seat 23 continues to move to the right and no longer moves backward. The straight rack 56 can continue to move backward under the engagement of the second movable pin 58 and the second inclined groove. When the straight rack 56 moves backward, it can drive the spur gear 57 , the driving shaft 24, the chuck 25 rotates, the clamp rotates, and when the clamp rotates, it can drive the raw material plate to flip over, even if the front end of the raw material plate tilts downward, when the chuck 25, the clamp, the second clamp seat 27, and the third slide pin 47 rotate to the specified position, that is, when the third slide pin 47 enters the inner wall of the diameter-changing groove 49, the chuck 25 and the second clamp seat 27 continue to rotate, and the second clamp seat 27 will move downward while moving in a circular motion. When the second clamp seat 27 moves downward, the clamp can be opened again, and the clamp no longer clamps The raw material plate is fixed, and the raw material plate in an inclined state can slide downward. A discharge guide plate 22 is provided on the discharge rack 21, and the raw material plate can fall onto the discharge guide plate 22 and flow to the designated position. After the raw material plate is unloaded, the driving seat 23 is controlled to move to the left and reset, and the corresponding clamp will rotate and move to the initial state, that is, the second clamp seat 27 will rotate and move upward to the initial position, that is, the clamp will close again. When the driving seat 23, the clamp, the long box 40, etc. move to the right to align the second sliding pin 41 with the second inclined surface 45 When this happens, the second sliding pin 41 engages with the second inclined surface 45, allowing the second sliding pin 41, the first clamping seat 26, and the first sliding pin 37 to move upward. When the first sliding pin 37 moves upward to the upper end position of the wedge-shaped stopper 35, the first clamping seat 26 is at its uppermost position, indicating that the clamp is in a stable open state. The trigger plate 30 returns to its initial position under the elastic force of the second spring 36. When the next raw material plate moves to the specified position, the clamp can close and clamp again, completing a cycle that repeats itself.

[0059] When the present invention is in use, when the row frame 6 and the suction cup 10 move downward to contact the raw material plate, the suction cup 10 can adsorb and fix the raw material plate, and then by controlling the row frame 6 to move upward and backward, the raw material plate can be transported to the feeding vehicle 11. By setting a pushing seat 14 that can move back and forth, the raw material plate can be pushed to the punching machine 17. When the punching machine 17 is working, rake pieces can be punched out on the raw material plate. The rake pieces are discharged from the discharge port under the action of gravity, and the rake pieces fall from the discharge port onto the rake piece conveying platform. Then, the rake pieces can be pushed into the punching machine 18 by the pushing of the pushing seat 14. The punching machine 18 can punch the rake pieces when it is working. The sheet is punched, and the remaining raw material sheet after punching can be moved out from the discharge port and moved to the unloading rack 21 under the drive of the pushing seat 14. Through the provided clamping mechanism, chuck 25, clamp, etc., when the remaining raw material sheet moves into the clamp, the clamp can be closed to clamp and fix the remaining raw material sheet. At this time, the pushing seat 14 moves, and the driving seat 23 can keep moving synchronously with the pushing seat 14. After all the raw material sheets are punched, when the driving seat 23 continues to move to one side, it can drive the remaining raw material sheet to separate from the punching machine 17 and completely drive into the unloading rack 21. When the driving seat 23 continues to move to one side to the specified position, it can make the chuck 25 5. The fixture rotates, that is, the corresponding raw material sheet can rotate, can be tilted during rotation, and the fixture can be opened to allow the residual material to fall into the designated position; the production line realizes automatic loading and unloading and punching, without the need for frequent manual intervention in material handling and punching operations. Compared with traditional manual or semi-automatic production lines, it greatly shortens the production cycle. The automatic loading and unloading function replaces repetitive labor such as manual handling and loading and unloading, reducing the dependence on a large number of general workers in the production process; the automatic punching process does not require manual operation of the punching equipment, reducing labor cost expenditure. At the same time, reducing manual operation also reduces the training cost caused by personnel turnover; the automatic punching process is controlled by The system operates strictly according to the preset program and can accurately control the position, size and depth of stamping and punching, avoiding the errors and unstable factors that may occur in manual operation, making the quality of the produced rake blades more stable, greatly improving product consistency, reducing the scrap rate and defective rate, and enhancing the competitiveness of the company's products; automatic loading and unloading and automatic punching reduce the direct contact between workers and stamping equipment, and reduce the risk of mechanical injuries caused by operational errors, fatigue, etc. during the loading and unloading and stamping process, effectively protecting the personal safety of workers, reducing the probability of safety accidents in the company, and reducing the economic losses and negative impacts caused by safety accidents.
