Description

Technical Field

[0001] The present invention relates to the technical field of harrow disc production, and in particular to a fully automatic stamping and punching production line for harrow discs. Background Art

[0002] In the field of modern agricultural machinery, as a key tillage component, the quality and production efficiency of harrow discs have a direct impact on the overall performance and operation effect of agricultural machinery. At present, in the production process of harrow discs, most of the stamping and punching processes still adopt traditional manual operation or semi-automatic equipment. The manual operation mode not only has low production efficiency and is difficult to meet the needs of large-scale production, but also due to the differences in the technical levels and working states of operators, it is difficult to ensure the dimensional accuracy and quality stability of harrow discs, resulting in a high scrap rate.

[0003] Although the existing semi-automatic equipment has improved the production efficiency to a certain extent, it still requires manual operations such as loading and unloading and positioning. For example, in the utility model patent with the publication number: CN215697131U and the name of a harrow disc stamping and forming device, although this device solves the problem of avoiding the risk of clothes being caught and personnel falling when staff pass by, its production automation degree is low, and there are problems such as high labor intensity and poor production process continuity. In addition, there are also safety hazards in the production process of manual operation and semi-automatic equipment, and operators are prone to being injured due to misoperation.

[0004] With the rapid development of agricultural mechanization, the market demand for harrow discs is increasing continuously, and at the same time, higher requirements are put forward for the quality and production efficiency of harrow discs. The traditional production method can no longer meet the needs of industry development, and there is a need for a new production line that can realize the automatic and continuous production of harrow disc stamping and punching, improve production efficiency and product quality, and reduce labor intensity and production costs.

[0016] The present invention has the following advantages compared with the prior art: When the present invention is in use, when the gantry and the suction cups move downward to contact the raw material plate, the suction cups can work to adsorb and fix the raw material plate. Then, by controlling the upward and backward movement of the gantry, the raw material plate can be transported to the feeding vehicle. By setting a push seat that can reciprocate, the raw material plate can be pushed to the punching machine. When the punching machine works, rake blades can be punched out on the raw material plate. Under the action of gravity, the rake blades are discharged from the discharge opening. The rake blades fall from the discharge opening onto the rake blade conveying platform, and then can be pushed into the punching machine by the pushing of the push seat. When the punching machine is working, punching operations can be performed on the rake blades. Driven by the push seat, the remaining material of the raw material plate after punching can be moved out from the discharge opening and moved to the unloading rack. Through the set clamping mechanism, chuck, fixture, etc., when the remaining material of the raw material plate moves into the fixture, the fixture can close to clamp and fix the remaining material of the raw material plate. At this time, the push seat moves, and the driving seat can move synchronously with the push seat. When all the raw material plates are punched, when the driving seat continues to move to one side, it can drive the remaining material of the raw material plate to separate from the punching machine and completely drive into the unloading rack. When the driving seat continues to move to a specified position on one side, it can make the chuck and the fixture rotate, that is, the corresponding remaining material of the raw material plate can rotate. When rotating, it can be inclined, and the fixture can be opened to make the remaining material fall into the specified position; This production line realizes automatic loading and unloading and punching, without the need for manual frequent intervention in material handling and stamping operations. Compared with traditional manual or semi-automatic production lines, the production cycle is greatly shortened. 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 link does not require manual operation of stamping equipment, reducing labor cost expenditure. At the same time, reducing manual operation also reduces the training cost caused by personnel flow; The automatic punching process is operated by the control system and runs strictly according to the preset program, which 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 the rejection rate and defective rate, and enhancing the competitiveness of the enterprise's products; Automatic loading and unloading and automatic punching reduce the direct contact between workers and stamping equipment, reducing the risk of mechanical injury caused by operation errors and fatigue operations of workers during loading and unloading and stamping, effectively protecting the personal safety of workers, reducing the probability of enterprise safety accidents, and reducing the economic losses and negative impacts brought by safety accidents.

Detailed implementation manners

[0036] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0037] As Figures 1 - 18As shown in the figure, the present invention provides a fully automatic stamping and punching production line for rake blades, including a punching machine 17. The punching machine 17 is provided with a feeding port and a discharging port. A raw material plate conveying platform is arranged at the feeding port. The raw material plate conveying platform includes a feeding cart 11. A feeding track 15 is arranged on the feeding cart 11. A pushing seat 14 capable of reciprocating movement is also arranged on the feeding cart 11. A material plate cart 1 is arranged at the front end of the feeding cart 11. A plurality of raw material plates are placed on the material plate cart 1. A feeding mechanism is arranged at the upper end of the feeding cart 11. The feeding mechanism includes a movable row frame 6. A plurality of suction cups 10 for adsorbing and fixing the raw material plates are arranged at the lower end of the row frame 6. When the row frame 6 moves, the raw material plates can be placed on the feeding cart 11. When the pushing seat 14 moves, the raw material plates can be pushed into the punching machine 17. A discharging device is arranged at the discharging port. The discharging device includes a discharging frame 21. A clamping mechanism is arranged on the discharging frame 21. The clamping mechanism includes a movable driving seat 23. A rotatable chuck 25 is installed on the driving seat 23. A clamp capable of opening and closing is arranged on the chuck 25. When the clamp closes, the remaining 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 remaining material can be driven to move synchronously to one side. When the driving seat 23 moves to a specified position on one side, the chuck 25 can rotate and the clamp can open to rotate the remaining material and place it at a specified position.

[0038] As Figures 1 - 10 shown, a lifting platform 2 is arranged on the material plate cart 1. The raw material plates are placed on the lifting platform 2. Through the arranged feeding mechanism, that is, the movable row frame 6, suction cups 10, etc., when the row frame 6 and the suction cups 10 move downward to contact the raw material plates, the suction cups 10 can work to adsorb and fix the raw material plates. The suction cups 10 are prior art and will not be elaborated here. Then, by controlling the row frame 6 to move upward and backward, the raw material plates can be transported onto the feeding cart 11, that is, the raw material plates are placed on the feeding track 15. The installation and shape of the feeding track 15 are as Figure 5 or Figure 6 , a plurality of roller columns are arranged on the feeding track 15. When the pushing seat 14 pushes the raw material plate to move, the friction force can be reduced. By arranging the pushing seat 14 capable of reciprocating movement, the raw material plates can be pushed into the punching machine 17. The punching machine 17 is used for punching the raw material plates to punch out a plurality of rake blades. As Figure 7As shown in the figure, a punching table is provided on the punching machine 17. An inlet is provided on the left side of the punching table, an outlet is provided on the right side, and a blanking opening is provided in the middle of the punching table. When the raw material plate is pushed onto the punching table and the punching machine 17 works, rake blades can be punched out on the raw material plate. Under the action of gravity, the rake blades are discharged from the blanking opening. A rake blade conveying platform is also provided at the blanking opening. A feeding track 15 and a pusher seat 14 are also provided on the rake blade conveying platform. The rake blade conveying platform has the same structure as the raw material plate conveying platform. The rake blades fall from the blanking opening onto the rake blade conveying platform and can be pushed into the punching machine 18 by the pusher seat 14. When the punching machine 18 works, punching operations can be performed on the rake blades. The punching machine 17 and the punching machine 18 are prior arts and will not be elaborated here. Driven by the pusher seat 14, the remaining material of the raw material plate after punching can be moved out from the outlet and moved onto the unloading rack 21. Through the provided clamping mechanism, chuck 25, fixture, etc., when the remaining material of the raw material plate moves into the fixture, the fixture can close to clamp and fix the remaining material of the raw material plate. At this time, the pusher seat 14 moves, and the driving seat 23 can move synchronously with the pusher seat 14. When all punching operations on the raw material plate are completed and the driving seat 23 continues to move to one side, it can drive the remaining material of the raw material plate to break away from the punching machine 17 and completely drive into the unloading rack 21. When the driving seat 23 continues to move to a specified position on one side, it can cause the chuck 25 and the fixture to rotate, that is, the corresponding remaining material of the raw material plate can rotate. When rotating, it can tilt, and the fixture can open to make the remaining material fall into the specified position. This production line realizes automatic loading and unloading and punching, without the need for manual frequent intervention in material handling and stamping operations. Compared with traditional manual or semi-automatic production lines, the production cycle is greatly shortened. 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 link does not require manual operation of the stamping equipment, reducing the labor cost expenditure. At the same time, reducing manual operation also reduces the training cost caused by personnel flow. The automatic punching process is operated by the control system and runs strictly according to the preset program, which 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 the product consistency, reducing the rejection rate and defective rate, and enhancing the competitiveness of the enterprise's products. Automatic loading and unloading and automatic punching reduce the direct contact between workers and stamping equipment, reducing the risk of mechanical injury caused by workers' operation errors, fatigue operations, etc. during loading and unloading and stamping, effectively protecting the personal safety of workers, reducing the probability of enterprise safety accidents, and reducing the economic losses and negative impacts brought by safety accidents.

[0039] The feeding mechanism includes a telescopic driving arm 3. A lifting arm 4 that can move up and down is installed on the driving arm 3. A gantry 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 gantry 6. 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.

[0040] As shown Figures 2 - 4 in the figure, the driving arm 3 can telescopically move back and forth, that is, it can drive the lifting arm 4, the gantry 6, the suction cups 10, etc. to move back and forth; the lifting arm 4 is slidably connected to the driving arm 3 up and down, and a driving rod 5 is also provided on the driving arm 3. When the driving rod 5 expands and contracts, it can drive the lifting arm 4 to move up and down, that is, drive the gantry 6, the suction cups 10, etc. to move up and down. The driving arm 3 and the driving rod 5 both belong to the prior art and will not be elaborated here; the gantry 6 is fixedly connected to the lower end of the lifting arm 4, the cross bar is fixedly connected to the gantry 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 cups 10 can be evenly installed.

[0041] A sleeve 8 is provided on one side of each of the square seats 7. A sleeve rod 9 is slidably connected to the inner wall of the sleeve 8. The suction cups 10 are fixedly connected to the lower ends of the sleeve rods 9. Error tolerance springs 39 are sleeved on the upper and lower ends of the outer surface of the sleeve rod 9, and an anti - detachment cap is also fixedly connected to the upper surface of the sleeve rod 9.

[0042] As shown Figures 4 - 6 in the figure, the sleeve 8 is fixed on the square seat 7, the sleeve rod 9 can be slidably connected to the inner wall of the sleeve 8 up and down, the anti - detachment cap can prevent the sleeve rod 9 from detaching from the sleeve 8, and the anti - detachment cap can also prevent the error tolerance spring 39 from falling off. By setting the error tolerance spring 39, the sleeve rod 9 and the suction cup 10 can have an up - and - down movement range. Since the upper end surface of the raw material plate is usually uneven, with the mutual cooperation of the sleeve rod 9, the suction cup 10 and the error tolerance spring 39, when the gantry 6 moves downward, each suction cup 10 can contact the upper end surface of the raw material plate, and the suction cup 10 can adsorb and fix the raw material plate more powerfully when adsorbing.

[0043] A first motor 12 is provided inside the material conveying vehicle 11. The output end of the first motor 12 is fixedly connected to a threaded rod 13. The pushing seat 14 is threadedly connected to the outer surface of the threaded rod 13, and the pushing seat 14 is also slidably connected to the inner wall of the material conveying vehicle 11. Flow - guiding plates 16 are also provided on both sides of the material conveying vehicle 11.

[0044] As shown Figures 5 - 6 in the figure, the first motor 12 is fixedly connected to the inner wall of the material conveying vehicle 11. When the first motor 12 is started, it can drive the threaded rod 13 to rotate. The motor is a prior art and will not be elaborated here; the pushing seat 14 can slide left and right inside the material conveying vehicle 11. A threaded hole matching the threaded rod 13 is provided inside the pushing seat 14, 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, under the meshing of the threaded rod 13 and the threaded hole, it can drive the pushing seat 14 to move left or right, that is, the pushing seat 14 reciprocates 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; by setting the flow - guiding plates 16, the raw material plate can be accurately pushed into the punching machine 17.

[0045] The discharging device further includes a drive box 19. A movable drive plate 20 is provided on the inner wall of the drive box 19. A drive seat 23 is installed at the lower end of the drive plate 20. A rotatable drive shaft 24 is provided on the inner wall of the drive seat 23. A chuck 25 is fixedly connected to the drive shaft 24. The fixture includes a first clamp seat 26 and a second clamp seat 27. The first clamp seat 26 and the second clamp seat 27 are movably installed on the chuck 25.

[0046] As Figures 8 - 10 shown, a rotatable lead screw is provided on the inner wall of the drive box 19. A nut is sleeved on the outer surface of the lead screw. The drive plate 20 is fixedly connected to the nut. When the lead screw rotates, it can drive the nut and the drive plate 20 to move; the chuck 25 is used to install the fixture. By providing a rotatable drive shaft 24, when the drive shaft 24 rotates, it can drive the chuck 25 and the fixture 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, it can control the fixture to open or close.

[0047] A spring seat 28 is fixedly connected to the chuck 25. 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 retaining boxes 34 are fixedly connected to the chuck 25. A wedge-shaped retaining block 35 is slidably connected to the inner wall of each retaining box 34. A second spring 36 that cooperates with the wedge-shaped retaining block 35 is also provided on the inner wall of each retaining box 34. First sliding pins 37 are fixedly connected to both sides of the first clamp seat 26.

[0048] As Figures 9 - 13 shown, the first clamp seat 26 can be slidably connected to the chuck 25 up and down. The spring seat 28 serves to support and fix the first spring 29. The upper ends of the first springs 29 are fixedly connected to the spring seat 28, and the lower ends are fixedly connected to the first clamp seat 26. The first springs 29 always have a downward thrust on the first clamp seat 26, so that the first clamp seat 26 has a downward clamping force under normal conditions. One or more first springs 29 can be provided; the installation and shape of the retaining boxes 34, the second springs 36, the wedge-shaped retaining blocks 35, and the first sliding pins 37 are as Figure 12 and Figure 13As shown, the wedge-shaped stopper 35 can slide left and right on the inner wall of the stopper box 34. The second spring 36 always has a driving force to the left on the wedge-shaped stopper 35, so that the wedge-shaped stopper 35 is in the outermost left state under normal conditions. The upper end surface of the wedge-shaped stopper 35 is a straight surface, and the lower end surface is an inclined surface. When the first sliding pin 37 is at the upper end of the wedge-shaped stopper 35, the wedge-shaped stopper 35 can block the first sliding pin 37 under the block of the straight surface of the wedge-shaped stopper 35. That is, at this time, the first sliding pin 37 and the first clamping seat 26 are in the uppermost position, and the fixture is in the open state. When the wedge-shaped stopper 35 moves to the inside of the stopper box 34 to the right, the wedge-shaped stopper 35 can be separated from the first sliding pin 37. At this time, the first sliding pin 37 and the first clamping seat 26 can move downward under the elastic force of the first spring 29. That is, the fixture can be closed to clamp and fix the remaining material of the raw material plate. When the first clamping seat 26 and the first sliding pin 37 move upward and reset from the bottom, the first sliding pin 37 can meet the inclined surface of the wedge-shaped stopper 35. Under the engagement 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 stopper box 34 and compress the second spring 36. When the first sliding pin 37 moves upward to be separated from the wedge-shaped stopper 35, the wedge-shaped stopper 35 can pop out to the outside of the stopper box 34 to the left 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 mutual cooperation of the inclined surface and the first sliding pin 37, the first clamping seat 26 and the first sliding pin 37 can move upward from the bottom to the upper position to reset, and the fixture is in the open state at this time.

[0049] A movable trigger plate 30 is provided on the chuck 25. U-shaped seats 33 are slidably connected to the stopper box 34. First connecting rods 32 that cooperate with the U-shaped seats 33 are provided on both sides of the trigger plate 30. Short pins 63 are provided on both sides of the wedge-shaped stopper 35. Oblique key grooves 38 that cooperate with the short pins 63 are provided on both sides of the U-shaped seats 33.

[0050] As Figures 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 baffle box 34 up and down. 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 block 35 can be driven to move right, that is, the wedge-shaped block 35 enters the inner wall of the baffle box 34; similarly, when the U-shaped seat 33 moves downward, the first sliding pin 37 and the wedge-shaped block 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, the U-shaped seat 33 can be driven 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 driving plate 20, the driving 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.

[0051] 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 a first long transverse groove 53, a first short oblique groove 54 and a short transverse groove 55 that match the first movable pin 51 are provided on the first track frame 52; a spur gear 57 is fixedly connected to the outer surface of the driving shaft 24, and a spur rack 56 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, and 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 match the second movable pin 58 are provided on the second track frame 59.

[0052] like Figures 16 - 18As shown, the driving seat 23 is slidably connected to the lower end of the driving plate 20 in the front-back direction. 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 also slide in the front-back direction at the lower end of the driving plate 20; an L-shaped connecting rod 50 is fixedly connected to the upper end of the driving seat 23, and the first live pin 51 is fixedly connected to the L-shaped connecting rod 50, which is equivalent to the first live pin 51 being fixedly connected to the driving seat 23. That is, when the driving seat 23 moves left and right, it can drive the first live pin 51 to move left and right, and when the first live pin 51 moves back and forth, it can make the driving seat 23 move back and forth; the drive shaft 24 is rotatably connected to the inner wall of the driving seat 23, the straight rack 56 can slide in the front-back direction on the inner wall of the driving seat 23, and the second live pin 58 is fixedly connected to the straight rack 56 through a connecting rod. When the second live pin 58 and the straight rack 56 move back and forth, under the meshing of the straight rack 56 and the spur gear 57, it can drive the spur gear 57, the drive shaft 24, and the chuck 25 to rotate, that is, the fixture rotates; the installation and shape of the first track frame 52, the first live pin 51, the second track frame 59, and the second live pin 58 are as Figure 18As shown, the first long horizontal groove 53 and the second horizontal inclined groove 60 are both arranged in parallel with the unloading rack 21. When the first live pin 51 meshes with the first long horizontal groove 53, when the driving seat 23 moves back and forth following the driving plate 20, it can always move left and right at the middle position of the unloading rack 21. When the second live pin 58 meshes with the second horizontal inclined groove 60, the straight rack 56 will be in a specified position, that is, at this time the straight rack 56 can only move left and right following the driving seat 23 and will not move back and forth. Since the driving seat 23 will not move back and forth under the meshing of the first live pin 51 and the first long horizontal groove 53, the straight rack 56 and the spur gear 57 will maintain a relatively static state and move left and right, and will not cause the driving shaft 24 to rotate, that is, the corresponding fixture will maintain a vertical state; the first short inclined groove 54 and the second short inclined groove 61 are arranged in parallel, and the second short inclined groove 61 is longer than the first short inclined groove 54. When the driving seat 23 moves to the right to a specified position, even when the first live pin 51 enters the inner wall of the first short inclined groove 54 and the second live pin 58 enters the inner wall of the second short inclined groove 61, when the driving seat 23 continues to move to the right, under the meshing of the first live pin 51 and the first short inclined groove 54, it can cause the driving seat 23, the fixture, etc. to move backward synchronously. Under the meshing of the second live pin 58 and the second short inclined groove 61, it can cause the straight rack 56 to move backward synchronously with the driving seat 23 and the spur gear 57, that is, at this time the fixture and the chuck 25 move backward while moving left synchronously. When the driving seat 23 moves to the right to make the first live pin 51 enter the inner wall of the short horizontal groove 55, at this time the second live pin 58 continues to move on the inner wall of the second short inclined groove 61. When the driving seat 23 continues to move to the right, under the meshing of the first live pin 51 and the short horizontal groove 55, the corresponding driving seat 23 will no longer move backward and will only move horizontally to the right. Under the meshing of the second live pin 58 and the second short horizontal groove 55, when the driving seat 23 moves to the right, the straight rack 56 can move backward while moving to the right following the driving seat 23. When the straight rack 56 moves backward, under the meshing with the spur gear 57, it can cause the spur gear 57, the driving shaft 24, the chuck 25, the fixture, etc. to rotate; that is, the fixture can rotate when the driving seat 23 moves to a specified position. When the driving seat 23 moves to the left to reset, under the mutual cooperation of the first live pin 51 and the first track rack 52, and the second live pin 58 and the second track rack 59, the fixture can be reversely flipped and reset, that is, it rotates to the vertical state and then moves to the left to reset.

[0053] The second chuck 27 is slidably connected to the chuck 25. A third sliding pin 47 is fixedly connected to one side of the second chuck 27. A fixed disk 46 is fixedly connected to one side end face of the driving seat 23. An arc groove 48 and a variable diameter groove 49 that cooperate with the third sliding pin 47 are provided on the fixed disk 46.

[0054] As Figure 11 and Figure 16 shown, the second chuck 27 can be slidably connected to the chuck 25 up and down. The installation and shape of the third sliding pin 47 and the fixed disk 46 are as Figure 16As shown in the figure, the drive shaft 24 penetrates through the fixed disk 46 and is rotatably connected to the inner wall of the fixed disk 46. The fixed disk 46 is fixedly connected to the drive seat 23, making the fixed disk 46 unable to rotate. Under the cooperation of the third sliding pin 47 with the arc groove 48 and the variable diameter groove 49, when the drive shaft 24 and the chuck 25 rotate, the second chuck 27 and the third sliding pin 47 can be driven to move synchronously in a circular motion. When the third sliding pin 47 moves circularly along the inner wall of the arc groove 48, at this time, the third sliding pin 47 and the second chuck 27 will not move downward. When the third sliding pin 47 enters the inner wall of the variable diameter groove 49, the drive shaft 24 and the chuck 25 continue to rotate. Under the engagement of the third sliding pin 47 with the variable diameter groove 49, the second chuck 27 can move downward while moving circularly. When the second chuck 27 moves downward, it can move away from the first chuck 26, and at this time, the fixture is in an open state. When the drive shaft 24 and the chuck 25 reverse and reset, under the engagement of the third sliding pin 47 with the variable diameter groove 49 and the arc groove 48, the corresponding second chuck 27 can move upward while moving circularly and reset to the initial position. That is, after the drive seat 23, the fixture, etc. move to the rightmost end, the fixture can rotate again, and can open after rotating to a specified angle.

[0055] A long box 40 is provided at the upper end of the first chuck 26. Second sliding pins 41 are slidably connected to the inner walls at both ends of the long box 40. Third springs 42 that cooperate with the second sliding pins 41 are also provided on the inner walls at both ends of the long box 40. A support frame 62 is fixedly connected to the drive box 19. Two double-sided wedges 43 that cooperate with the second sliding pins 41 are provided at the lower end of the support frame 62. First inclined surfaces 44 are provided at one ends of the double-sided wedges 43, and second inclined surfaces 45 are provided at the other ends of the double-sided wedges 43.

[0056] As Figure 14 and Figure 15 shown, a support column is fixedly connected to the upper end of the first chuck 26, and the long box 40 is fixedly connected to the support column. It is equivalent to the long box 40 being fixedly connected to the first chuck 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, making the second sliding pin 41 in an extended state under normal conditions. The support frame 62 plays a role in supporting and fixing the double-sided wedges 43. The shape of the double-sided wedges 43 is as 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 are disengaged 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. Under the contact and engagement of the second sliding pin 41 and 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 at this time 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 fixture is in the open state; under the mutual cooperation of the unloading device and the clamping mechanism, when the raw material plate residue moves to the specified position to the right, that is, when the raw material plate contacts and presses the trigger plate 30 to move to the right, it will cause the wedge-shaped stopper 35 to move to the right. After the wedge-shaped stopper 35 moves to the right and is disengaged from the first sliding pin 37, at this time the first clamping seat 26 moves downward under the elastic force of the first spring 29, and the first clamping seat 26 can squeeze and clamp the raw material plate. At this time, the fixture is in the closed state to clamp and fix the raw material plate. By controlling the driving seat 23 and the pushing seat 14 to move to the right synchronously, the raw material plate can be stably driven to move to the right, so that the raw material plate can be accurately moved to the specified position, improving the punching accuracy; when the driving seat 23 moves to the right, under the engagement of the first live pin 51 and the first long horizontal groove 53, the driving seat 23 can be kept moving to the right parallel to the unloading rack 21, that is, the driving seat 23, the fixture, etc. will not move forward or backward. Under the engagement of the second live pin 58 and the second horizontal inclined groove 60, the straight rack 56 will move to the right synchronously and statically with the spur gear 57, that is, the corresponding chuck 25, the fixture, etc. will not rotate. When the driving seat 23, the fixture, the long box 40, the second sliding pin 41, etc. move to meet the first inclined surface 44, at this time the second sliding pin 41 will only move inward and will not drive the first clamping seat 26 to move, without affecting the clamping effect of the fixture. When the driving seat 23, the fixture, etc. move to the right so that the first live pin 51 enters the inner wall of the first short inclined groove 54 and the second live pin 58 enters the inner wall of the second short inclined groove 61, at this time the raw material plate residue is separated from the punching machine 17 and completely enters the unloading rack 21. When the driving seat 23 continues to move to the right, under the engagement of the first live pin 51 and the first short inclined groove 54 and the second live pin 58 and the second short inclined groove 61, the driving seat 23, the straight rack 56, the spur gear 57, the fixture, etc. can move to the right and backward synchronously. When the fixture 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 disengage from the contact with the unloading rack 21. When the driving seat 23 continues to move to the right until the first live pin 51 enters the inner wall of the short horizontal groove 55 and the second live pin 58 continues to move to the right along the inner wall of the second inclined groove, at this time, when the driving seat 23 continues to move to the right, it will no longer move backward. The straight rack 56 can continue to move backward under the meshing of the second live pin 58 and the second inclined groove. When the straight rack 56 moves backward, it can drive the spur gear 57, the drive shaft 24, and the chuck 25 to rotate. The fixture rotates, and when the fixture rotates, it can drive the raw material plate to flip, that is, the front end of the raw material plate tilts downward. When the chuck 25, the fixture, the second chuck 27, and the third sliding pin 47 rotate to the designated position, that is, when the third sliding pin 47 enters the inner wall of the variable diameter groove 49, at this time, when the chuck 25 and the second chuck 27 continue to rotate, the second chuck 27 will move downward while moving in a circular motion. When the second chuck 27 moves downward, it can open the fixture. At this time, the fixture no longer clamps and fixes the raw material plate, and the raw material plate in the inclined state can slide downward. The unloading rack 21 is provided with an unloading guide plate 22, and the raw material plate can fall onto the unloading guide plate 22 and flow to the designated position. After the raw material plate is unloaded, the driving seat 23 is controlled to move leftward to reset, and the corresponding fixture will rotate and move to the initial state, that is, the second chuck 27 will rotate and move upward to the initial position, that is, the fixture closes again. When the driving seat 23, the fixture, the long box 40, etc. move to the right until the second sliding pin 41 meets the second inclined surface 45, under the contact and meshing of the second sliding pin 41 and the second inclined surface 45, the second sliding pin 41, the first chuck 26, the first sliding pin 37, etc. can move upward. When the first sliding pin 37 moves upward to the upper end position of the wedge-shaped stop block 35, at this time, the first chuck 26 is at the uppermost position, that is, the fixture is in a stable open state, and the trigger plate 30 resets to the initial position under the elastic force of the second spring 36. When the next raw material plate moves to the designated position, the fixture can close and clamp again, realizing a cycle of repeated operations.

[0057] When the present invention is in use, when the gantry 6 and the suction cup 10 move downward to contact the raw material plate, the suction cup 10 can work to adsorb and fix the raw material plate. Then, by controlling the upward and backward movement of the gantry 6, the raw material plate can be transported onto the feeding vehicle 11. By providing a push seat 14 that can reciprocate, the raw material plate can be pushed into the punching machine 17. When the punching machine 17 works, rake blades can be punched out on the raw material plate. Under the action of gravity, the rake blades are discharged from the blanking opening, fall onto the rake blade conveying platform from the blanking opening, and then can be pushed into the punching machine 18 by the pushing of the push seat 14. When the punching machine 18 is working, punching operations can be performed on the rake blades. Driven by the push seat 14, the remaining material of the raw material plate after punching can be moved out from the discharge opening and moved onto the unloading rack 21. By providing a clamping mechanism, a chuck 25, a fixture, etc., when the remaining material of the raw material plate moves into the fixture, the fixture can close to clamp and fix the remaining material of the raw material plate. At this time, the push seat 14 moves, and the driving seat 23 can move synchronously with the push seat 14. When all the raw material plates are punched, when the driving seat 23 continues to move to one side, it can drive the remaining material of the raw material plate to break away from the punching machine 17 and completely drive into the unloading rack 21. When the driving seat 23 continues to move to a specified position on one side, it can cause the chuck 25 and the fixture to rotate, that is, the corresponding remaining material of the raw material plate can rotate. During rotation, it can be tilted, and the fixture can open to make the remaining material fall into the specified position; This production line realizes automatic loading and unloading and punching, without frequent manual intervention in material handling and stamping 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 link does not require manual operation of the stamping equipment, reducing the labor cost expenditure. At the same time, reducing manual operation also reduces the training cost caused by personnel flow; The automatic punching process is operated by the control system and runs strictly according to the preset program, which 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 the product consistency, reducing the rejection rate and defective rate, and enhancing the competitiveness of the enterprise's products; Automatic loading and unloading and automatic punching reduce the direct contact between workers and stamping equipment, reducing the risk of mechanical injuries caused by workers' operational errors and fatigue operations during loading and unloading and stamping, effectively protecting the personal safety of workers, reducing the probability of enterprise safety accidents, and reducing the economic losses and negative impacts caused by safety accidents.
