Description

Technical Field

[0001] This utility model relates to the field of forging processing technology, and in particular to a forging bending and positioning device. Background Technology

[0002] The existing forging bending die includes a lower die and an upper die. Both the lower die and the upper die have grooves for placing the forging. The mating surfaces of the lower die and the upper die are staggered in a stepped manner. When the forging is placed between the lower die and the upper die, the forging is bent in the groove when the upper die and the lower die are mated.

[0003] A search revealed that patent CN220361846U discloses a forging bending and positioning device. This device uses a rotating rod to move clamping plates, which hold and fix the forging in place. When the forging is bent downwards by a pressure column, the friction between the forging and the clamping plates is very high, making it difficult to bend the two ends of the forging upwards, especially for thinner forgings. Furthermore, the upper and lower molds of this device cannot be quickly changed, making it unsuitable for processing different forgings. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a forging bending positioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a forging bending and positioning device, comprising a base, wherein columns are fixed at the four corners of the upper surface of the base, and a top plate is fixedly connected to the top of the four columns. A hydraulic telescopic rod is fixed in the middle of the top plate, and a detachable pressing component is fixed at the bottom telescopic end of the hydraulic telescopic rod. A recess is formed in the middle of the upper surface of the base, and a detachable bottom mold component is engaged inside the recess. Sliding grooves are formed on both sides of the recess on the upper surface of the base, and a positioning component is installed inside each sliding groove.

[0006] Furthermore, the positioning component includes a bidirectional lead screw that is rotatably connected to the sidewall of the slide groove via a bearing. Two sliders are rotatably connected to the surface of the bidirectional lead screw via threads, and the two sliders are slidably connected to the slide groove. A clamping plate is fixed on the upper surface of each of the two sliders, and several spherical grooves are opened on the adjacent sides of the two clamping plates. A ball is rotatably connected inside each spherical groove.

[0007] Furthermore, one end of the bidirectional lead screw extends to the outside of the base and is fixedly connected to a handle.

[0008] Furthermore, the bottom mold assembly includes a locking block that is inserted into the sink groove, a module is fixed on the upper surface of the locking block, and a molding groove is formed on the upper surface of the module.

[0009] Furthermore, an electromagnet is fixed to the bottom wall of the settling tank, and the clamping block is made of iron.

[0010] Furthermore, a connecting plate is fixed to the bottom telescopic end of the hydraulic telescopic rod, and multiple screws are fixed to the lower surface of the connecting plate. Each screw is rotatably connected to a nut. The pressing assembly includes a top mold, and a mounting plate is fixed to the upper surface of the top mold. Multiple connecting holes for the screws to pass through are provided on the mounting plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a forging bending and positioning device is disclosed, comprising a base 1, with columns 2 fixed at the four corners of the upper surface of the base 1, and a top plate 3 fixedly connected to the top of the four columns 2. A hydraulic telescopic rod 4 is fixed in the middle of the top plate 3, and a detachable pressing component 5 is fixed at the bottom telescopic end of the hydraulic telescopic rod 4. A groove 101 is provided in the middle of the upper surface of the base 1, and a detachable bottom mold component 6 is engaged inside the groove 101. Slide grooves 102 are provided on both sides of the groove 101 on the upper surface of the base 1, and a positioning component 8 is installed inside each slide groove 102.

[0023] The positioning assembly 8 includes a bidirectional lead screw 82 that is rotatably connected to the side wall of the slide groove 102 via a bearing. Two sliders 81 are rotatably connected to the surface of the bidirectional lead screw 82 via a thread, and the two sliders 81 are slidably connected to the slide groove 102. A clamping plate 83 is fixed on the upper surface of each of the two sliders 81. Several spherical grooves 84 are opened on the adjacent sides of the two clamping plates 83, and a ball bearing 85 is rotatably connected inside each spherical groove 84.

[0024] In this embodiment, by rotating the bidirectional lead screw 82, the bidirectional lead screw 82 can drive the two sliders 81 to move closer or further away from each other, thereby causing the two clamping plates 83 to move closer or further away from each other, and using the clamping plates 83 to clamp and limit the forging.

[0025] One end of the bidirectional lead screw 82 extends to the outside of the base 1 and is fixedly connected to a handle 86.

[0026] By providing a handle 86 on the outside of the base 1, it is easy to rotate the bidirectional lead screw 82 outside the base 1.

[0027] The bottom mold assembly 6 includes a locking block 61 that is inserted into the recess 101. A module 62 is fixed on the upper surface of the locking block 61, and a molding groove 63 is formed on the upper surface of the module 62.

[0028] When installing the bottom mold assembly 6, simply insert the locking block 61 into the sink 101.

[0029] An electromagnet 7 is fixed to the bottom wall of the settling tank 101, and the locking block 61 is made of iron.

[0030] After the locking block 61 is inserted into the sink 101, the electromagnet 7 is energized to attract and fix the locking block 61. When the bottom mold assembly 6 is disassembled for replacement, the electromagnet 7 is de-energized to remove the locking block 61 from the sink 101.

[0031] The bottom telescopic end of the hydraulic telescopic rod 4 is fixed with a connecting plate 41, and multiple screws 42 are fixed on the lower surface of the connecting plate 41. Each screw 42 is rotatably connected with a nut 43. The pressing assembly 5 includes a top mold 51. A mounting plate 52 is fixed on the upper surface of the top mold 51. Multiple connecting holes 53 for passing through the screws 42 are provided on the mounting plate 52.

[0032] The top mold 51 is fixedly connected to the connecting plate 41 by the screw 42, thus allowing the top mold 51 to be disassembled and replaced.

[0033] Working principle: The forging to be processed is placed horizontally on the surface of module 62. Then, the two-way lead screws 82 on both sides are rotated respectively. The two-way lead screws 82 drive the two corresponding clamping plates 83 to move closer to each other until the balls 85 on the clamping plates 83 are in contact with the side of the forging. The two clamping plates 83 are used to position the forging. Then, the hydraulic telescopic rod 4 is activated to drive the top die 51 to descend. The top die 51 is used to squeeze and bend the forging. The two ends of the forging can be raised upward along the surface of the clamping plates 83. By setting the balls 85, the friction between the forging and the clamping plates 83 can be reduced, and deformation at the contact position between the forging and the clamping plates 83 can be avoided.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation.
