The function of the first motor 12 is to provide a rotational force for the first threaded rod 13. The motor is a prior art and will not be described in detail. When the first motor 12 is started, it can drive the corresponding first threaded rod 13 to rotate, and when the first threaded rod 13 rotates, it can drive the corresponding first threaded seat 14 and the semicircular pressure rod 15 to move forward or backward. , the positions of the two semicircular pressure rods 15 can be adjusted, and adaptive adjustments can be made according to the thickness of the steel plate, and the first threaded seat 14 and the first threaded rod 13 are threadedly connected and have a self-locking function, that is, when the first motor 12 and the first threaded rod 13 do not rotate, the corresponding first threaded seat 14 and the semicircular pressure rod 15 are in a fixed position and will not move on the first driving plate 9 or the second driving plate 10; the two semicircular pressure rods 15 are in close contact at the initial position, which can make the semicircular pressure rods 15 contact more closely and accurately when squeezing the steel plate to bend.

[0040] A circular seat 16 is fixedly connected to the upper end of the outer surface of the support shaft 11, and three evenly distributed square sliders 25 are slidably connected to the inner wall of the circular seat 16.

The inner sides of the lower ends of the scissor-type telescopic frame 20 are respectively hinged on the upper end surfaces of the circular ring seat 16, and the outer sides of the upper ends of the scissor-type telescopic frame 20 are respectively hinged on the corresponding expansion plates 24. The outer sides of the lower ends of the scissor-type telescopic frame 20 are respectively provided with first sliding pins 23, and the inner end surfaces of the expansion plates 24 are respectively fixed with limited seats 21. The inner walls of the limited seats 21 are respectively provided with first key grooves 22, and the first sliding pins 23 are respectively slidably connected to the inner walls of the first key grooves 22. When the scissor-type telescopic frame 20 is expanded outward or closed inward, the corresponding first sliding pins 23 can slide on the inner walls of the first key grooves 22, and the square slider 25 can slide inward or outward on the inner wall of the circular ring seat 16. When the second threaded rod 17 rotates, it can drive the threaded cylinder 18 moves downward or upward, and when the threaded barrel 18 moves downward or upward, the scissor-type telescopic frame 20 expands and moves outward or closes inward. When the scissor-type telescopic frame 20 expands and moves outward or closes inward, it can drive the corresponding expansion plate 24 to move outward or inward. When the expansion plate 24 moves outward, it will squeeze the inner wall of the mold barrel 26, thereby fixing the mold barrel 26. When the expansion plate 24 closes inward, the corresponding expansion plate 24 can be disengaged from the mold barrel 26.

[0042] The inner walls of the left and right ends of the mold cylinder 26 are respectively slidably connected with long slides 29, and long key grooves 30 are respectively opened on the long slides 29. Long pins 31 are respectively provided on the inner walls of the long key grooves 30. Side seats 32 slidably connected to the long slides 29 are respectively provided on the outer surfaces of the long pins 31. Arc-shaped inclined grooves 65 matching the long pins 31 are respectively opened on the inner walls of the mold cylinder 26. Anti-slip seats 41 are respectively slidably connected to the inner walls of the long pins 31. The first wedge blocks 40 are respectively fixed to the corresponding anti-slip seats 41. The inner walls of the long pins 31 are also respectively provided with first support seats 38, and the first support seats 38 are respectively provided with first springs 39 matching the corresponding anti-slip seats 41.

[0043] like Figure 7-Figure 12 As shown, the long slide plate 29 can slide on the inner wall of the mold cylinder 26. The long key groove 30 is provided to enable the long pin 31 to move up and down on the inner wall of the long key groove 30. The side seat 32 is provided to be slidably connected to the long slide plate 29 up and down. The side seat 32 can limit the long pin 31 to move up and down on the inner wall of the long slide plate 29. The long pin 31 and the arc-shaped inclined groove 65 are provided as shown in FIG.

The anti-slip seat 41 can prevent the first wedge block 40 from being separated from the long pin 31, and can limit the first wedge block 40 to slide only to the left and right on the inner wall of the long pin 31. One end of the first spring 39 is respectively fixed to the first support seat 38, and the other end of the first spring 39 is respectively fixed to the anti-slip seat 41.

A wedge-shaped block 40 has an outward thrust, so that the first wedge-shaped block 40 is in an extended state under normal conditions; the rear end of the first wedge-shaped block 40 is an inclined surface, and the front end is a straight surface. When the first driving plate 9, the second driving plate 10, and the semicircular pressure rod 15 swing from the back to the front, that is, when the steel plate is squeezed and bent, the semicircular pressure rod 15 will encounter the inclined surface of the first wedge-shaped block 40 when moving forward in a circular motion. When the semicircular pressure rod 15 contacts the inclined surface of the first wedge-shaped block 40, it continues to When the semicircular pressure rod 15 moves forward in a circular motion, the first wedge-shaped block 40 can be driven to move inwardly into the inner wall of the long pin 31. After entering the inner wall of the long pin 31, the first wedge-shaped block 40 will compress the first spring 39. When the semicircular pressure rod 15 moves forward to disengage from the first wedge-shaped block 40, the first wedge-shaped block 40 can move outwardly and reset under the elastic force of the first spring 39. When the semicircular pressure rod 15 moves in a circular motion from front to back and resets, the semicircular pressure rod 15 will When it contacts the straight surface of the first wedge block 40 and is blocked by the straight surface of the first wedge block 40, the semicircular pressure rod 15 continues to move backward and can drive the first wedge block 40, the long pin 31, etc. to move synchronously in a backward circular direction. When the long pin 31 moves in a backward circular direction, it will move upward while moving in a backward circular direction under the engagement with the arc-shaped inclined groove 65. When the first wedge block 40 moves upward, it will drive the bent steel plate to move upward, thereby causing the steel plate to detach from the outer surface of the mold cylinder 26.

Fig.11 As shown, when the semicircular pressure rod 15 moves from front to back in a circular motion, even if the first wedge block 40 and the long pin 31 move backward and upward at the same time, when the long pin 31 moves upward, it can drive the connecting rod 37, the movable pin 34, etc. to move upward. When the movable pin 34 moves upward, through the engagement of the movable pin 34 with the first transverse groove 35, the movable pin 34 can move upward stably without moving left or right, that is, the two movable pins 34 will not move inward or outward. When the long pin 31, the movable pin 34, etc. move upward When the movable pin 34 enters the inner wall of the first inclined groove 36, the long pin 31 and the movable pin 34 continue to move upward. Under the meshing of the movable pin 34 and the first inclined groove 36, the movable pin 34 can move upward and inward at the same time. When the movable pin 34 moves inward, it can drive the corresponding connecting rod 37, the first supporting seat 38, the first spring 39, the first wedge block 40 and the like to move inward synchronously, even if the first wedge block 40 moves inward to the inner wall of the long pin 31, until the first wedge block 40 and the semicircular pressure The rod 15 is out of contact; the left and right inner walls of the mold cylinder 26 are respectively fixed with first stop seats 27, the front ends of the first tension springs 28 are respectively fixed to the corresponding first stop seats 27, and the rear ends of the first tension springs 28 are respectively fixed to the corresponding long slides 29. The first tension springs 28 always have a forward pulling force on the long slide 29, even if the long slide 29 is at the frontmost position under normal conditions, the long pin 31 and the first wedge block 40 are at the frontmost and lowermost positions under normal conditions. When the long pin 31, the first wedge block 40, and the long slide When the first wedge block 40 moves backward, the first wedge block 40 can be stretched to the upper end position, and the first wedge block 40 will be moved inward under the engagement of the movable pin 34 and the first inclined groove 36, that is, it will enter the inner wall of the long pin 31 and disengage from the semicircular pressure rod 15. At this time, the long slide 29, the long pin 31, the first wedge block 40, etc. will move forward and reset under the pulling force of the first tension spring 28, even if the first wedge block 40, the long pin 31, etc. move downward to the lower position of the front end.

[0046] A side plate 42 is fixedly connected to the rear side of the upper end surface of the base 1, and a supporting seat 53 that can move up and down is slidably connected to the front end surface of the side plate 42. A plurality of steel plates are placed on the supporting seat 53. An extended supporting plate 66 is slidably connected to the inner wall at the rear end of the mold cylinder 26. Two small springs 67 that cooperate with the extended supporting plate 66 are also fixedly connected to the inner wall at the rear end of the mold cylinder 26. When the supporting seat 53 moves downward, the steel plate can be placed on the upper end surface of the extended supporting plate 66.

[0047] like Fig. 9 , Fig.13 As shown, the support seat 53 can be slidably connected to the inner wall of the side plate 42 up and down, and the side plate 42 plays a supporting and limiting role for the support seat 53 and other parts. The support seat 53 is used to store the steel plate to be bent. The extension support plate 66 can slide back and forth on the inner wall of the mold cylinder 26. The front end of the small spring 67 is fixedly connected to the inner wall of the mold cylinder 26, and the rear end of the small spring 67 is fixedly connected to the front end surface of the rear end of the extension support plate 66. The small spring 67 can have a backward thrust on the extension support plate 66, so that the extension support plate 66 is in an extended state under normal conditions; when the extension support plate 66 is in the extended state, it can support the steel plate, and when the support seat 53 moves downward, it can project the steel plate Place it on the upper end surface of the extension support plate 66, and then adjust the semicircular pressure rod 15. When the semicircular pressure rod 15 moves forward and contacts the extension support plate 66, the extension support plate 66 can slide and retract back and forth under the setting of the small spring 67. When the semicircular pressure rod 15 contacts and squeezes the steel plate, it no longer moves forward. At this time, when the semicircular pressure rod 15 moves forward in a circular motion, it can squeeze and bend the steel plate, thereby squeezing it into the shape of the mold cylinder 26. When the semicircular pressure rod 15 moves from front to back to reset, inclined surfaces are respectively provided on both sides of the extension support plate 66. Under the setting of the inclined surfaces, the extension support plate 66 will not prevent the semicircular pressure rod 15 from moving backward cylindrically to reset.

[0048] The inner wall of the bottom end of the material supporting seat 53 is slidably connected with a push plate 56 that matches the steel plate, and the inner wall of the rear end of the material supporting seat 53 is fixedly connected with two second springs 57 that match the push plate 56. The front ends of the material supporting seat 53 are respectively provided with baffle plates 54, and the baffle plates 54 are respectively slidably connected with long sliders 61, and the inner walls of the long sliders 61 are respectively slidably connected with second wedge blocks 62, and the inner walls of the bottom ends of the long sliders 61 are respectively fixedly connected with third springs 63 that match the second wedge blocks 62; the left and right end surfaces of the material supporting seat 53 are respectively rotatably connected with idler wheels 58, and the left and right sides of the front end surface of the side plate 42 are respectively fixedly connected with fixed racks 59 that mesh with the idler wheels 58, and the long sliders 61 are respectively fixedly connected with movable racks 60 that mesh with the idler wheels 58, and a discharge port 55 is opened on the front side of the lower end of the material supporting seat 53.

[0049] like Fig.13 , Figure 16-Figure 17As shown, the push plate 56 can be slidably connected to the inner wall of the support seat 53, the rear ends of the second springs 57 are respectively fixed to the support seat 53, and the front ends of the second springs 57 are respectively fixed to the push plate 56. The second spring 57 always has a forward thrust on the push plate 56, so that the push plate 56 can have a forward thrust, that is, a forward thrust on the steel plate; the material blocking plate 54 is set, the steel plate can be blocked so that the steel plate is in the support seat 53; the long slider 61 can be slidably connected to the material blocking plate 54 up and down, that is, the limit long slider 61 and the movable rack 60 can only go up The second wedge-shaped block 62 is provided with a square plate 64 at the front end, and the square plate 64 can be slidably connected to the long slider 61. The function of the square plate 64 is to prevent the second wedge-shaped block 62 from being separated from the long slider 61, and to limit the second wedge-shaped block 62 to slide only forward and backward on the inner wall of the long slide 29. The function of the third spring 63 is to push the square plate 64 and the second wedge-shaped block 62 to have a backward driving force, so that the second wedge-shaped block 62 is in the rearmost position under normal conditions, that is, the extended state. The upper end of the second wedge-shaped block 62 is an inclined surface, and the lower end is a right-angled surface. When the second wedge-shaped block 62 moves downward When the second wedge block 62 moves downward, the right-angled surface will contact the frontmost steel plate, and through the set discharge port 55, the steel plate will be pushed downward when the second wedge block 62 moves downward, that is, the steel plate is moved out from the discharge port 55, and only one steel plate can be moved out at a time. When the second wedge block 62 moves downward to the bottom, the steel plate can be completely pushed out to the inner wall of the support seat 53. At this time, the next steel plate will move forward to the front end and close to the inner wall of the baffle plate 54 under the thrust of the push plate 56. When the second wedge block 62 moves upward from the bottom to reset, the inclined surface of the second wedge block 62 will contact the next steel plate. When the second wedge block 62 is in the state of being moved downward, the straight surface of the second wedge block 62 can push the steel plate downward again, thereby feeding the material repeatedly. The installation and shape of the fixed rack 59, the idler wheel 58 and the movable rack 60 are as shown in FIG. Fig.16As shown, the inner wall at the center of the idler wheel 58 is fixed with a rotating shaft, and the rotating shaft is rotatably connected to the inner wall of the support seat 53. The idler wheel 58 is rotatably connected to the support seat 53 through the rotating shaft. When the support seat 53 moves downward, it can drive the idler wheel 58, the long slider 61, the second wedge block 62, the movable rack 60, etc. to move downward synchronously. When the idler wheel 58 moves downward, the idler wheel 58 can be driven to rotate through the meshing of the idler wheel 58 and the fixed gear. When the idler wheel 58 rotates, it can drive the movable rack 60 to move downward. When the movable rack 60 moves downward, it can drive the long slider 61 , the second wedge block 62, etc. move downward on the support seat 53, so the second wedge block 62 can push the steel plate downward to the specified position; when the support seat 53 moves upward, it can drive the idler wheel 58, the movable rack 60, the long slider 61, the second wedge block 62, etc. to move upward synchronously. When the idler wheel 58 moves upward, it will drive the movable rack 60, the long slider 61, the second wedge block 62, etc. to move upward on the support seat 53 through engagement with the fixed rack 59, thereby resetting the support seat 53, the long slider 61, and the second wedge block 62 to their initial state.

[0050] A partial gear ring 43 is fixedly connected to the first driving plate 9 and the second driving plate 10 respectively, and a wide gear 44 is meshed inside the two partial gear rings 43. A one-way transmission structure is provided on the inner wall of the wide gear 44. A cylindrical cam 49 is provided at the output end of the one-way transmission structure. Two fixing pins 50 matching with the cylindrical cam 49 are provided at the lower end of the support seat 53. Second gear seats 51 are fixedly connected to the lower sides of the left and right ends of the front end surface of the side plate 42 respectively, and long springs 52 matching with the support seat 53 are fixedly connected to the upper end surfaces of the second gear seats 51.

[0051] like Figure 13-14 As shown, the long spring 52 always has an upward thrust on the support seat 53, which can make the support seat 53 be at the top position under normal conditions. The installation and shape of the local gear ring 43 and the wide gear 44 are as shown in FIG. Fig.13 As shown, by meshing the partial gear ring 43 with the wide gear 44, when the first drive plate 9 and the second drive plate 10 swing forward or backward in a circular motion, the partial gear ring 43 can be driven to move forward or backward. When the partial gear ring 43 moves forward or backward in a circular motion, the corresponding wide gear 44 can be driven to rotate forward or reversely. The two partial gear rings 43 are installed in an up-and-down staggered manner to avoid motion interference. The installation and shape of the cylindrical cam 49 and the fixing pin 50 are as shown in FIG. Fig.14As shown, fixing plates are respectively fixedly connected to the outer surfaces of the fixing pins 50, and the fixing plates are respectively fixedly connected to the lower end surfaces of the supporting seats 53. The fixing plates support and fix the fixing pins 50, which is equivalent to the fixing pins 50 being fixedly connected to the lower ends of the supporting seats 53. When the cylindrical cam 49 rotates, it can drive the corresponding two fixing pins 50 to move downward, that is, the supporting seats 53 move downward, and the long spring 52 is compressed. When the cylindrical cam 49 rotates 180 degrees, the fixing pin 50 will disengage from the cylindrical cam 49. At this time, the supporting seats 53 and the fixing pin 50 will move upward and reset under the spring of the long spring 52, even if the supporting seats 53 and the fixing pin 50 move upward and reset to the top initial state; through the one-way transmission structure set, when the wide gear 44 is reversed, When the first driving plate 9 and the second driving plate 10 are swung from back to front, the wide gear 44 can be driven to rotate forwardly through the meshing of the local gear ring 43 and the wide gear 44. At this time, the cylindrical cam 49 will not rotate. When the first driving plate 9 and the second driving plate 10 are swung from front to back to reset, the local gear ring 43 can drive the wide gear 44 to rotate in the opposite direction after meeting the wide gear 44. The reverse rotation of the wide gear 44 can drive the cylindrical cam 49 to rotate. The rotation of the cylindrical cam 49 will drive the support seat 53 to move downward, thereby feeding, and then through the local gear ring 43 and the arc-shaped inclined groove 65 and the long pin 31, when the first driving plate 9 and the second driving plate 10 swing from back to front, the semicircular pressure rod 15 will squeeze and bend the steel plate, and will not drive the long pin 31, the cylindrical cam 49, etc. to work. When the first driving plate 9 and the second driving plate 10 swing from front to back to reset, they can first drive the two first wedge blocks 40 and the long pin 31 to move upward and backward. When the long pin 31 and the first wedge block 40 move upward, they can drive the bent steel plate to move upward, even if the steel plate is separated from the outer surface of the mold cylinder 26. When the long pin 31 and the first wedge block 40 move upward to the top, the bent steel plate will move upward to the top position, and then the bent steel plate will be removed. When the first driving plate 9 and the second driving plate 10 swing from front to back to reset, they can first drive the two first wedge blocks 40 and the long pin 31 to move upward and backward. When the long pin 31 and the first wedge block 40 move upward, they can drive the bent steel plate to move upward, even if the steel plate is separated from the outer surface of the mold cylinder 26. When the long pin 31 and the first wedge block 40 move upward to the top When the second drive plate 10 and the like continue to swing backward in a circle, the corresponding semicircular pressure rod 15 will disengage from the first wedge block 40, and the first wedge block 40, the long pin 31 and the like will reset under the tension of the first tension spring 28. When the first drive plate 9 and the second drive plate 10 continue to swing backward, the local gear ring 43 can meet the wide gear 44. After the local gear meets the wide gear 44, the local gear ring 43 can drive the wide gear 44 to reverse. When the wide gear 44 reverses, it can drive the cylindrical cam 49 to rotate. When the cylindrical cam 49 rotates, it can drive the support seat 53 to move downward. When the support seat 53 moves downward, it can put the steel plate onto the extended support plate 66, thereby realizing loading again. The operation can be repeated in a cycle and will not be repeated.

[0052] The one-way transmission structure includes a transmission shaft 45, a circular ring gasket 46 is fixedly connected to the outer surface of the transmission shaft 45, two pawls 47 are hinged at the non-center of the upper end surface of the circular ring gasket 46, the inner wall of the wide gear 44 is provided with ratchet teeth matching with the pawls 47, two spring sheets 48 matching with the corresponding pawls 47 are fixedly connected to the circular ring gasket 46, and the cylindrical cam 49 is fixedly connected to the upper end of the outer surface of the transmission shaft 45.

[0053] like Figure 14-15 As shown, the transmission shaft 45 is rotatably connected to the inner wall of the base 1, and the wide gear 44 is rotatably connected to the outer surface of the transmission shaft 45, which is equivalent to the wide gear 44 being rotatably connected to the base 1, and the limited wide gear 44 can only rotate; the installation and shape of the ratchet, pawl 47, and spring sheet 48 are as shown Fig.15 As shown, the spring sheet 48 can always have an outward elastic force on the pawl 47, so that the pawl 47 is in the outermost end position under normal conditions, that is, the pawl 47 is in meshing with the ratchet teeth under normal conditions, that is, when the ratchet teeth are meshing with the pawl 47, when the wide gear 44 rotates forward, the ratchet teeth will be relatively displaced with the pawl 47, that is, the ratchet teeth will not drive the pawl 47, the transmission shaft 45, and the cylindrical cam 49 to rotate. When the wide gear 44 rotates reversely, the ratchet teeth can drive the pawl 47, the transmission shaft 45, and the cylindrical cam 49 to rotate, thereby realizing that the wide gear 44 and the cylindrical cam 49 can only transmit rotational force in one direction through the one-way transmission structure.

[0054] When the present invention is in use, by setting a rectangular frame that can move left and right, the first driving plate 9 and the second driving plate 10 can be driven to swing forward synchronously, that is, the corresponding semicircular pressure rods 15 can move circumferentially along the outer periphery of the mold cylinder 26, and the mold cylinder 26 is used to support and block the steel plate, so that the steel plate is deformed along the outer surface of the mold cylinder 26 when the steel plate is squeezed. After the steel plate is placed in a specified position, when the first driving plate 9 and the second driving plate 10 swing, the semicircular pressure rods 15 can be driven to move forward circumferentially, and the semicircular pressure rods 15 can squeeze the steel plate and make the steel plate deformed along the outer surface of the mold cylinder 26, so that the steel plate is bent into a desired shape. When the first driving plate 9 and the second driving plate 10 swing backward and reset, the two first wedge blocks 40 can be driven to move upward. The upward movement of the first wedge blocks 40 can push the steel plate that is bent and attached to the outer surface of the mold cylinder 26 upward, so that the bent steel plate is pushed to the upper end position of the mold cylinder 26, thereby facilitating taking and improving work efficiency.
