[0013] Preferably, the outer wall of the lower mold is fixedly connected to a limiting rod, and two groups of limiting rods are provided, and the two groups of limiting rods are symmetrically distributed on both sides of the lower mold.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0031] See also Figures 1-9 The utility model proposes a metal part bending device, including a support base 1, a blanking plate 11 is fixed to the inner wall of the support base 1, the outer wall of the top of the support base 1 is fixedly connected to a hydraulic cylinder 2, the output end of the hydraulic cylinder 2 is fixedly connected to an upper mold 3, and a lower mold 4 is provided directly below the upper mold 3. The outer wall of the lower mold 4 is fixedly connected to a limit rod, and there are two groups of limit rods, and the two groups of limit rods are symmetrically distributed on both sides of the lower mold 4. The lower mold 4 is provided with a slot, and the slot is slidably connected to a sliding seat 41. The sliding seat 41 is elastically connected to the inner wall of the lower mold 4 through an elastic spring. Through the sliding seat 41 and the elastic spring structure, during the bending process of the metal part, the sliding seat 41 can slide downward under pressure, so that the metal part can better adapt to the pressure changes in the bending process, reducing the influence of stress concentration on the quality of the metal part. The outer wall of the sliding seat 41 is embedded with a magnet, and a lifting mechanism is provided in the lower mold 4.

[0032] In the embodiment of the present utility model, in order to be able to eject the formed workpiece, specifically, the ejection mechanism includes a pusher block 42, the pusher block 42 is slidably connected to the inner wall of the lower mold 4, the outer wall of the pusher block 42 is provided with a card slot 40, the pusher block 42 is elastically connected to the inner wall of the lower mold 4 by a return spring 43, a guide rod 44 is fixedly connected to the outer wall of the pusher block 42, the guide rod 44 passes through the lower mold 4 and is slidably connected to the lower mold 4, the outer wall of the guide rod 44 is fixedly connected to a cross bar 45, and the extrusion rod 31 is fixedly connected to the outer wall of the upper mold 3;

[0033] Furthermore, the lower mold 4 is slidably connected to a limit block 46, which is elastically connected to the inner wall of the lower mold 4 via an elastic spring. The limit block 46 is provided with a through slot 47, and an inclined block 48 is slidably connected to the through slot 47. The outer wall of the inclined block 48 is fixedly connected to a rod 49, which passes through the lower mold 4 and is slidably connected to the lower mold 4. The rod 49 is elastically connected to the inner wall of the lower mold 4 via an elastic spring.

[0034] When the pusher 42 is fully engaged in the lower mold 4, the locking groove 40 on the pusher 42 will coincide with the locking groove 46, and the pressure on the locking groove 46 disappears. At this time, the locking groove 40 on the pusher 42 will rebound into the inner part of the locking groove 40 under the action of the elastic spring, thereby completing the limitation of the pusher 42. Then the metal part is placed on the outer wall of the sliding seat 41, and then the hydraulic cylinder is started again. 2, then the upper mold 3 will extrude the metal part. At this time, under the action of pressure, the sliding seat 41 moves downward, and the metal part is deformed. When the metal part processing is completed, the hydraulic cylinder 2 is started to drive the upper mold 3 to move upward. At the same time, in the process, the pressure on the sliding seat 41 disappears. At this time, the sliding seat 41 will drive the metal part back to its original position. When the hydraulic cylinder 2 drives the upper mold 3 to return to the highest point, the bottom of the extrusion rod 31 will squeeze the rod body 49, causing the rod body 49 to move inside the lower mold 4. When the rod body 49 moves, the inclined block 48 will squeeze the limit block 46, causing the limit block 46 to move downward, thereby releasing the limit of the push block 42, and then the push block 42 will be pushed out by the elastic force of the return spring 43, thereby pushing the metal part to the blanking plate 11, thereby completing the purpose of blanking, and no manual removal is required.
