DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] Reference Figures 1-5 For an embodiment of the utility model, it discloses a plate bending device, specifically the device comprises a machine table 1, a die holder 2 mounted on the machine table 1 and a die head 3 slidingly connected on the machine table 1, the die head 3 comprises a connecting seat and a stamping head, during processing, the plate is placed between the die head 3 and the die holder 2, the up-down movement of the die head 3 is used to complete the bending work of the plate, of course, the bending angle is defined by the forming angle of the stamping head of the die holder 2, the mode is a conventional means for the person skilled in the art, and no more description is made here;

[0026] The upper portion of the machine table 1 is provided with a driving assembly 4 for driving the up-down movement of the die head 3, and the upper portion of the machine table 1 is provided with a positioning assembly 5.

[0027] The positioning assembly 5 comprises a fixed seat 51 embedded on the machine table 1, the fixed seat 51 is provided with a moving-in assembly 52 and a rotating assembly 53, and the rotating assembly 53 is provided with a positioning rod 54.

[0028] In some embodiments, the moving-in assembly 52 comprises two guide rods 521 mounted in the fixed seat 51, and a carrier 522 is slidingly connected between the two guide rods 521, specifically, the fixed seat 51 in the embodiment is a U-shaped structure, and the fixed seat 51 is mounted in a slot at the upper end of the machine table 1.

[0029] The fixed seat 51 is further rotatably connected with a screw rod 523, and the screw rod 523 is threadedly connected with the carrier 522, that is, when the length of the bending position needs to be changed in the embodiment, the screw rod 523 is rotated, and the screw rod 523 drives the carrier 522 to move forward or backward by the thread driving force, so that the forward or backward position of the carrier 522 is adjusted, and the forward or backward position of the positioning rod 54 is changed, for example, when the positioning rod 54 moves backward, the length of the plate entering the machine table 1 is increased, and the bending position is close to the rear end of the plate, and vice versa.

[0030] Further, the rotating assembly 53 in the embodiment comprises a rotating shaft 531 rotatably connected with the carrier 522.

[0031] The top end of the rotating shaft 531 is fixedly connected with the positioning rod 54, and the bottom end is fixedly connected with a worm gear 532, the inside of the fixed seat 51 is rotatably connected with a rectangular rod 533, and the outside of the rectangular rod 533 is slidably connected with a worm rod 534 engaged with the worm gear 532.

[0032] It should be noted that in the embodiment, the worm rod 534 is designed to slide, which is used to adapt to the forward or backward movement of the carrier 522, and the worm gear 532 cannot drive the worm rod 534 due to the structural characteristics of the worm gear 532 and the worm rod 534, so when the carrier 522 moves forward or backward, the worm gear 532 drives the worm rod 534 to move linearly by the engagement force of the worm gear 532 and the worm rod 534, and when the carrier 522 needs to be adjusted to the angle, the rectangular rod 533 is rotated, the rectangular rod 533 is adapted to the rectangular hole in the worm rod 534 to drive the worm rod 534 to rotate, so that the positioning rod 54 is rotated by the rotating shaft 531, and the angle of the positioning rod 54 is adjusted, and when the plate is inserted against the positioning rod 54, the plate is inclined, so that the processing requirement of the workpiece with a bevel is met.

[0033] On the basis of the above embodiment, one end of the screw rod 523 and the rectangular rod 533 in the embodiment is fixedly connected with a rod portion 55 penetrating the outside of the fixed seat 51, the outside of the rod portion 55 is sleeved and slidably connected with a handle portion 57 by a spring 56, the handle portion 57 and the opposite surface of the fixed seat 51 are provided with a clamping piece 58, and as a preferred, the clamping piece 58 in the embodiment can be a friction plate, that is, the end of the handle portion 57 and the outside of the fixed seat 51 are fixedly connected with friction plates, and in the initial state, the two friction plates are tightly fitted to avoid the free rotation of the rod portion 55, and of course, in other embodiments, the clamping piece 58 can be provided with a clamping tooth disc, and the same technical effect can be achieved.

[0034] In addition, when the screw rod 523 and the rectangular rod 533 need to be rotated, the handle part 57 can be pulled outward to separate the clamping part 58 between the handle part 57 and the fixed seat 51, and then the screw rod 523 and the rectangular rod 533 can be freely rotated. It should be noted that a T-shaped slot is formed on the outer side of the handle part 57 in the embodiment, and a guide bolt is threadedly connected to the outer side of the rod part 55, and the guide bolt and the T-shaped slot are slidably matched to guide and limit the handle part 57.

[0035] Of course, in order to realize intuitive viewing of the adjusted position, the inner side of the fixed seat 51 is provided with a first scale mark 511 in the moving direction of the carrier 522, and the carrier 522 is provided with a second scale mark 524 in the rotating direction of the positioning rod 54. In the embodiment, the first scale mark 511 is provided as a length value scale, and the second scale mark 524 is provided as an angle value scale. Indicating needles can also be installed on the carrier 522 and the positioning rod 54 to avoid intuitive viewing of the current adjusted value.

[0036] It should be noted that the driving assembly 4 in the embodiment includes a hydraulic cylinder 41 pinned to the machine table 1. The bottom of the hydraulic cylinder 41 is pinned to the machine table 1 through a connecting seat. A circular shaft 42 is fixed to the middle part of the machine table 1. A swing arm 43 is rotatably connected to the outer side of the circular shaft 42. One end of the hydraulic cylinder 41 is pinned to the swing arm 43. The other end of the swing arm 43 is pinned to a connecting rod 44. The other end of the connecting rod 44 is pinned to the die head 3. Specifically, when the die head 3 needs to be controlled to move up and down, the swing arm 43 is driven to rotate by the hydraulic cylinder 41. When the swing arm 43 rotates, the die head 3 is driven to move up and down by the connecting rod 44. In this way, the height of the die head 3 can be controlled to complete the stamping of the plate.

[0037] In summary, through the design of the moving assembly 52 and the rotating assembly 53, the front and back displacement and the inclined position of the positioning rod 54 can be changed to meet the processing requirements of different positions and angle inclination of the plate during bending. In this way, the applicability of the entire device is improved.

[0038] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto.
