Technical Field

[0001] The invention relates to the technical field of bending equipment, in particular to a universal cylinder type continuous bending die. Background Art

[0002] A mold is a tool that, under the action of external force, makes a blank into a product of a specific shape and size. It is widely used in forming processes such as punching, extrusion, casting and bending.

[0003] Under the pressure of the bending dynamic die, the metal sheet is first deformed, and then at the beginning of the bending, the sheet is bent freely. As the dynamic die applies pressure to the sheet, the sheet and the surface of the fixed die gradually come close to each other, and at the same time, the radius of curvature and the bending force arm gradually become smaller. The pressure is continued until the stroke ends, so that the dynamic and fixed dies and the sheet are in full contact at three points. At this time, a bend is completed, and it becomes a bending.

[0004] Parts with bending shapes are generally first punched into a size suitable for bending by punching, and then the part is processed into the final shape by a bending die.

[0005] At present, the traditional bending of metal sheets will be affected by the punching pressure during mold closing, which will cause the metal sheet blank to be affected and offset, resulting in inaccurate bending and easy product scrapping. Summary of the invention

[0034] The third embodiment, as Figure 1-Figure 9 As shown, based on the first and second embodiments: A feeding mechanism 5 is installed at the top of the base 1 and near the lower template 41. The feeding mechanism 5 includes a connecting base 51 and a storage assembly 52. ​​The connecting base 51 is fixedly installed at the top of the base 1 and near the lower template 41. The storage assembly 52 is installed in the middle of the top of the strip pad 43. A hydraulic cylinder 53 is fixedly installed in the middle of the top of the connecting base 51 through a bracket. A guide rail 54 is fixedly installed at the top of the connecting base 51 and near the extended end of the hydraulic cylinder 53.

A feeding tongue 56 is installed, and a pushing block 57 is fixedly installed at one end of the feeding tongue 56 away from the connecting beam 55, and a supporting plate 58 is fixedly installed on the top of the pushing block 57 and close to the feeding tongue 56. The blank enclosed in the baffle 524 falls from the discharge port 522 to the top of the lower template 41, and the staff starts the hydraulic cylinder 53 to work, and uses the telescopic end of the hydraulic cylinder 53 to shrink, so that the connecting beam 55 is subjected to a pulling force, and under the guidance of the guide rail 54, the connecting beam 55 smoothly drives the feeding tongue 56 to move, and the pushing block 57 is pushed by the feeding tongue 56 to move in the direction close to the V-shaped groove 42, so that the blank at the bottom can be pushed, thereby loading.

[0035] The connecting base 51 and the lower template 41 are installed at the same height, and the inner side surface of the bottom of the connecting beam 55 is in contact with the outer side surface of the guide rail 54 .

[0036] The top of the push block 57 is flush with the top of the support plate 58 . There are two support plates 58 , and the two support plates 58 are symmetrically installed along the feeding tongue 56 .

[0037] The material storage assembly 52 includes a rectangular flat plate 521, the bottom of which is fixedly mounted in the middle of the top of the strip pad 43, a material discharge port 522 being opened in the middle of the rectangular flat plate 521, a material leakage seat 523 being fixedly mounted on the top of the rectangular flat plate 521 and close to the material discharge port 522 by screws, a baffle 524 being fixedly mounted on the side of the top of the material leakage seat 523, the material leakage seat 523 being evenly mounted on the top of the rectangular flat plate 521, so that four vertically mounted baffles 524 form a circular enclosure, the staff places the blanks to be bent in the center of the space enclosed by the baffle 524, so that the blanks are arranged in order, which is convenient for subsequent continuous loading, thereby facilitating continuous bending of the blanks.

[0038] There are four leakage seats 523, and the four leakage seats 523 are evenly installed on the top of the rectangular flat plate 521 and close to the discharge port 522.

[0039] When the telescopic end of the hydraulic cylinder 53 is extended, the connecting beam 55 is pushed outward by the telescopic end of the hydraulic cylinder 53, so that the feeding tongue 56 is driven to move outward, thereby causing the pushing block 57 and the baffle 524 to be driven to move outward together for reset. The pushing block 57 is used to move out of the bottom of the blank, and the lifting force on the pushing block 57 disappears, so that the blank is dropped again, which is convenient for loading one by one.

[0040] When in use, firstly, the guide plate 452 is connected to the lower template 41 by bolts, and under the limiting effect of the square limiting pin 451, the position of the guide plate 452 can be finely adjusted, thereby adjusting the distance between the two symmetrical guide plates 452 to adapt to blanks of different sizes; Then, the blanks to be bent are placed in the center of the space enclosed by the baffle 524 so that the blanks are arranged in order. At this time, the blanks enclosed in the baffle 524 fall from the discharge port 522 to the top of the lower template 41; At this time, the staff starts the hydraulic cylinder 53 to work, and uses the telescopic end of the hydraulic cylinder 53 to shrink, so that the connecting beam 55 is pulled, and under the guidance of the guide rail 54, the connecting beam 55 steadily drives the feeding tongue 56 to move, and the pushing block 57 is pushed by the feeding tongue 56 to move toward the direction close to the V-shaped groove 42, so that the blank at the bottom can be pushed, so as to load the material; After the blank to be bent is pushed over, the end of the blank contacts the guide slope 454 on the guide plate 452. Under the guiding action of the guide slope 454, the blank is placed directly above the V-shaped groove 42. Two symmetrical guide plates 452 are placed on both sides of the blank to limit the position of the blank and prevent it from being skewed. The staff starts the driving cylinder 32 to work. Under the support of the upper template 31, the punch head 34 can be driven to move downward and upward by extending and contracting the telescopic end of the driving cylinder 32, and the height of the punch head 34 can be adjusted, so that the punch head 34 can be used to apply a punching force to the blank, which is convenient for punching and bending the blank and helps to shape the blank after being punched. At the same time, when the punch head 34 moves downward, the bending plate 35 can be driven to move downward together, and the opening of the U-shaped notch 36 is downward, so that the U-shaped notch 36 is stuck on the square block 44, and the bending plate 35 continues to move downward, so that the punch head 34 can be supported and guided, so that the overall structure interacts with each other, and stable and accurate stamping is performed; Moreover, when the feed tongue 56 moves to drive the push block 57 to move linearly to feed the material, the support plate 58 moves together with the feed tongue 56 toward the direction close to the V-shaped groove 42, so that the support plate 58 is directly below the baffle 524, and a lifting force can be applied to the blank surrounded by the baffle 524, so that the blank can fall freely.

[0041] When the telescopic end of the hydraulic cylinder 53 is extended, the connecting beam 55 is pushed outward by the telescopic end of the hydraulic cylinder 53, so that the feeding tongue 56 is driven to move outward, thereby causing the pushing block 57 and the baffle 524 to be driven to move outward together for reset. The pushing block 57 is used to move out the bottom of the blank, and the lifting force on the pushing block 57 disappears, so that the blank is dropped again, which is convenient for loading one by one. This reciprocating process can be carried out for continuous stamping and bending processing.
