[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In one embodiment, see Figures 1-8 A bending and forming machine for automobile brake parts includes a base plate 1, which is a flat plate structure. Cross-reinforcement ribs can be provided at the bottom to improve the structural strength of the entire base plate 1. Support columns 2 are vertically provided at the four corners of the upper surface of the base plate 1. The machine also includes a die mechanism 3 and a punch mechanism 4. The die mechanism 3 includes a fixed crossbeam 5 arranged at the lower position of the support column 2, the front and rear ends of the fixed crossbeam 5 are fixedly connected to the front and rear support columns 2, and the fixed crossbeam 5 is arranged on the left and right sides above the base plate 1 in a front-to-back state, and a left-to-right supporting slide 7 is arranged between the left and right fixed crossbeams 5. The two supporting slides 7 are arranged on the front and rear sides above the base plate 1, and a sliding seat 9 arranged in a front-to-back direction is slidably connected on the left and right sides of the supporting slide 7. The front and rear sides of the sliding seat 9 are slidably connected to the supporting slide 7, and a rotating shaft 11 arranged in a front-to-back direction is provided on the side of the sliding seat 9 close to the center of the base plate 1. The rotating shaft 11 is rotatably connected to the lower surface of the rotating support plate 12. A material discharge groove 13 is provided on the upper surface of the support plate 12. The cross section of the material discharge groove 13 is a semicircular structure. When the rod needs to be bent, it can be placed in the material discharge groove 13. The material discharge groove 13 can play a positioning effect, and a guide protrusion 14 is provided on the side of the sliding seat 9 away from the center of the bottom plate 1. The upper end of the guide protrusion 14 is an arc surface. In order to improve the stability of the support slide 7, an auxiliary support block 8 is fixedly connected to the middle part of the support slide 7, and two auxiliary support plates 6 separated outward are provided on the lower surface of the auxiliary support block 8. The lower end of the auxiliary support plate 6 is fixedly connected to the bottom plate 1, and the middle part of the support slide 7 is supported by the auxiliary support block 8 and the auxiliary support plate 6, so as to withstand the gravity generated when the upper pressure is pressed down and bent; The punch mechanism 4 is arranged above the die mechanism 3, and includes two left-right sliding beams 17. The left and right ends of the sliding beam 17 are slidably connected to the top of the support column 2, and the middle part of the sliding beam 17 is rotatably connected to the rotating shaft 11 arranged in the front and rear directions. The middle part of the rotating shaft 11 is fixedly connected to the middle part of the flip plate 22. The flip plate 22 can rotate forward or reverse with the rotating shaft 11, and a triangular protrusion 27 is provided in the middle of the upper and lower sides of the flip plate 22. The triangular protrusion 27 is a triangular structure with a raised middle part, and the ends of the triangular protrusion 27 are chamfered, so that when the triangular protrusion 27 drops, it will fit with the rotating support plates 12 on both sides, and a limiting slot 28 is provided on the side of the triangular protrusion 27. The cross-section of the limiting slot 28 is also a semicircular structure, and the limiting slot 28 can just buckle In the upper half of the rod, the rod will not shake at will when it is bent, and guide top blocks 26 that cooperate with the guide protrusions 14 are provided on the left and right sides of the triangular protrusion 27. The guide top blocks 26 are right-angled triangle structures with the inclined surfaces facing the center direction of the base plate 1. When the triangular protrusion 27 moves downward, the two side surfaces of the triangular protrusion 27 are respectively fitted with the rotating support plates 12 on both sides. At this time, the guide top blocks 26 are also fitted with the guide top blocks 26, thereby achieving a tightening effect. A flip motor 21 is provided in the middle of the front sliding beam 17. The output shaft of the flip motor 21 is fixedly connected to the first bevel gear 20, and the first bevel gear 20 is meshed with the second bevel gear 19. The second bevel gear 19 is fixedly connected to the front end of the flip main shaft 18. The flip motor 21 controls the flip plate 22 to flip through gear transmission.

[0025] In one aspect of this embodiment, the end of the discharge trough 13 closest to the center of the base plate 1 is open, and the end of the discharge trough 13 farther from the center of the base plate 1 is closed. That is, when the left and right sides of the rod are placed in the discharge trough 13, the rod can extend through the open ends of the discharge trough 13, so that the bottom of the discharge trough 13 is completely in contact with the outside of the rod, and the end of the rod just touches the inside of the closed end of the discharge trough 13, so that the rod is restrained from moving left or right. Therefore, when the rod is placed in the discharge trough 13, the front, back, left, and right sides of the rod are all restricted, and the rod can only be bent as the rotating support plate 12 rotates.

[0026] In one embodiment of the present invention, a return spring 10 is provided between the fixed crossbeam 5 and the sliding seat 9 to drive the sliding seat 9 to move toward the center of the base plate 1. After the two rotating support plates 12 rotate to a parallel state, the rotating support plates 12 and the sliding seat 9 are in contact with each other, and the ends of the rotating support plates 12 are flat. The return spring 10 is sleeved on the outside of the support slide 7. The return spring 10 prevents the triangular protrusion 27 from moving upward and disengaging from the rotating support plates 12 after a single bend. At this time, the rod is placed in the discharge trough 13 of the rotating support plates 12. If the return spring 10 is not provided, the two sliding seats 9 will separate to the sides under the action of the weight of the rod, and the rod will fall. Therefore, a return spring 10 with a smaller elastic force is provided to prevent the sliding seat 9 from separating. Alternatively, a damping block can be provided between the sliding seat 9 and the support slide 7 so that the sliding seat 9 does not slip when only subjected to the weight of the rod. And because the reset spring 10 is provided, when the rotating support plates 12 on both sides rotate to a horizontal state, the two sliding seats 9 approach each other, and the ends of the rotating support plates 12 are pressed against each other. At this time, the entire die mechanism 3 is in a straight state, which is convenient for clamping the rods that need to be bent.

[0027] In one aspect of this embodiment, a magnetic plate 16 is provided on the rotating support plate 12, and a magnetic block 15 is provided on the sliding seat 9 to cooperate with the magnetic plate 16. When the rotating support plate 12 rotates to a straight position, the magnetic block 15 will attract the magnetic plate 16. Since the rotating shaft 11 rotates to connect the side of the rotating support plate 12 away from the center of the base plate 1, when there is no suction force, the end of the rotating support plate 12 closer to the center of the base plate 1 will fall and deflect downward. At this time, due to the action of the magnetic force, the rotating support plate 12 can be maintained after rotating to a horizontal position, making it easier for the operator to clamp the rod.

[0028] In one case of this embodiment, a top plate 24 is provided at the end of the support column 2, and a lifting cylinder 25 is provided on the top plate 24. The piston rod of the lifting cylinder 25 is fixedly connected to an extension beam 23 fixedly connected to the sliding beam 17. The extension beam 23 is a U-shaped structure and is arranged on the left and right sides facing forward and backward. The front and rear ends of the extension beam 23 are respectively fixedly connected to the ends of the front and rear sliding beams 17, so that the sliding beam 17 is pushed up and down by the lifting cylinder 25. The air sources of the two lifting cylinders 25 can be connected together, so that the piston rods of the two lifting cylinders 25 on the left and right sides can be extended and retracted synchronously.

[0029] During the implementation of this embodiment, the base plate 1 is placed stably on the ground, the lifting cylinder 25 is started, the sliding beam 17 is moved to a high place, the sliding seat 9 is separated to the left and right sides, and the rotating support plate 12 is rotated to a horizontal state, the magnetic block 15 adsorbs the magnetic plate 16, and the sliding seat 9 is released. Under the action of the return spring 10, the two sliding seats 9 are close to each other, and the ends of the rotating support plates 12 are pressed against each other. At this time, return springs 10 are provided on both sides, so the two rotating support plates 12 are in a centered state, and the rods to be bent are placed in the discharge trough 13 with the left and right ends of the rods against the closed ends of the discharge troughs 13 on both sides. At this time, the two rotating support plates 12 are slightly pushed open by the rods, and the clamping work of the rods is completed.

[0030] After the first bending process, the turning motor 21 is started, and the turning motor 21 drives the turning plate 22 to rotate through the gear transmission, and the triangular protrusion 27 with a larger angle is rotated downward, and the lifting cylinder 25 is started. The lifting cylinder 25 drives the sliding beam 17 to move downward, and the triangular protrusion 27 moves downward. The arc chamfer at the lower end of the triangular protrusion 27 will first contact the middle part of the rod. At this time, the middle part of the rod is bent downward, and the guide top blocks 26 on both sides will contact the guide protrusion 14, and the two sliding seats 9 move close to each other. When the triangular protrusion 27 is completely lowered, the surfaces of the rotating support plates 12 on both sides are completely fitted with the inclined surfaces on both sides of the triangular protrusion 27. At this time, the sliding seats 9 can no longer move close to each other, and the guide top blocks 26 and guide protrusions 14 can no longer slide with each other. The entire die mechanism 3 and the punch mechanism 4 are completely fitted and stopped, and the rod is now subjected to the first bending process.

[0031] After the second bending process, the lifting cylinder 25 is started in the reverse direction, and the sliding crossbeam 17 drives the triangular protrusion 27 to move upward and disengage from the rotating support plate 12. At this time, since the rod has been bent into a downward concave state, the two rotating support plates 12 are also in this state and there will be no problem of resetting. Moreover, since the sliding seats 9 on both sides will not separate to the sides under the action of the return springs 10, the rotating support plate 12 and the rod are in a stable state. By turning the motor 21, the triangular protrusion 27 with a smaller angle is rotated to the downward state, and the triangular protrusion 27 falls again to perform a second bending process on the rod, and this time the bending angle is larger. After completion, the triangular protrusion 27 moves upward, and the operator will rotate the rotating support plate 12 to a horizontal state. At this time, the rod bent into an L shape will be disengaged from the discharge chute 13 of the rotating support plate 12, and a new straight rod can be put in again for subsequent bending processing.

[0032] The present invention is applicable to a bending and forming machine for automobile brake parts. By arranging two triangular protrusions 27 with different angles on both sides of a flip plate 22 and moving downward to bend the rod part with a rotating support plate 12, the rod part can be bent at two different angles after one clamping, thereby improving work efficiency. Moreover, when the rotating support plate 12 is rotated to a horizontal state for subsequent clamping, the rod part bent into an L shape will automatically fall off, thereby further improving the clamping efficiency of the rod part.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
