Description

Technical Field

[0001] The present application relates to the technical field of metal forging processing, and particularly to a forging clamping device for cylindrical titanium forgings. Background Art

[0002] Forging is a processing method that uses forging machinery to apply pressure to a metal blank, causing it to undergo plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and dimensions. It is one of the important forming methods for metal parts, which can improve the structure of the metal, enhance the mechanical properties of the metal, and ensure that the metal parts have good mechanical properties to meet the usage requirements.

[0003] Forging can be classified according to different classification criteria. According to the forging temperature, it can be divided into hot forging, warm forging, and cold forging. One way of hot forging is as shown in the attached Figures 1-3 description. One side of the forging to be forged is clamped by a clamp body, and the forging is driven to move intermittently in the direction indicated by the arrow in Figures 2-3 . While the forging press performs local forging operations on the forging through the upper and lower dies during the intermittent stop of the forging movement, and then, with the gradual drive of the clamp body, the through-length forging processing of the forging is realized.

[0004] During the gradual forging process of the forging, the forging operations of the upper and lower dies of the forging press will cause the size of the forging in the horizontal width direction to increase, as shown in Figure 4 . When forging near the clamp body, the increase in the horizontal width of the forging will act on the clamp body, as shown in Figure 5 , and then this acting force will drive the clamp body to deflect outwards. Since the clamp body is usually hinged and driven by a driving cylinder inside, this deflecting acting force will act on the piston of the driving cylinder, which will cause problems such as damage to the driving cylinder or fracture of the clamp body. After the clamp body fractures, there will be a safety hazard of the forging falling. Summary of the Invention

[0005] Aiming at the above problems, the present application aims to provide a forging clamping device for cylindrical titanium forgings, which, when the forging deforms, the clamp body deforms along with the forging under the action of clamping the forging, thereby solving the hard acting force caused by the deformation of the forging on the clamp body and the damage to the driving cylinder.

[0006] To achieve the above object, the technical solution adopted in the present application is as follows: A forging clamping device for cylindrical titanium forgings, the clamping device includes a clamping sleeve, clamping bodies are symmetrically hinged left and right inside the clamping sleeve, and driving cylinders hinged to each clamping body are arranged inside the clamping sleeve. It is characterized in that each of the clamping bodies is detachably connected to the driving cylinder, and the clamping bodies are symmetrical after being disassembled from the driving cylinder, and the clamping bodies are movably clamped on the titanium forging.

[0007] Preferably, a detachable hinge rod is inserted through the hinge joint between the driving cylinder and the clamping body, and a disassembly hole for inserting the hinge rod is formed in the clamping sleeve.

[0008] Preferably, limiting protrusions are arranged on the inner sides of the symmetrical clamping bodies, and a compression spring is movably sleeved on the limiting protrusions.

[0009] Preferably, driving protrusions that contact the ends of the titanium forgings are arranged on the inner sides of the symmetrical clamping bodies.

[0010] The beneficial effects of the present application are as follows: The clamping device of the present application detachably connects each clamping body to the driving cylinder, and after the clamping body and the driving cylinder are disassembled, the symmetrical clamping bodies clamp the titanium forging movably. When the clamping body is connected to the driving cylinder, the driving cylinder can drive the clamping body to clamp the end of the forging, drive the movement of the forging and its detachment from the forging press. When the clamping body is separated from the driving cylinder, the clamping body clamps the forging movably. When the forging deforms, the clamping body deforms along with it under the action of clamping the forging, thereby solving the hard force exerted on the clamping body by the deformation of the forging and the damage to the driving cylinder.

[0022] In order to enable ordinary technicians in the field to better understand the technical solution of this application, the technical solution of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Refer to Figures 1-9 A forging clamping device for a cylindrical titanium forging as shown. This clamping device includes a jacket 1. Inside the jacket 1, clamping bodies 2 are symmetrically hinged left and right. Inside the jacket 1, a driving cylinder 3 is provided which is hingedly connected to each clamping body 2. During the forging operation, the driving cylinder 3 drives the symmetric clamping bodies 2 to hinge and rotate towards each other to clamp one end of the forging. Then, the other end of the forging is placed and supported on the lower die of the forging press. The forging press drives the upper die to move downward and act on the upper surface of the forging, thereby realizing the forging operation on the forging. After one forging is completed, the entire jacket 1 moves horizontally a certain length to drive the forging to move. After the movement stops, the upper die continues to move downward to perform the forging operation on the surface of the forging. In this way, the forging operation along the entire length of the forging can be realized.

[0024] To solve the problem that the forging deformation of the forging affects the clamping body 2 and the driving cylinder 3 when approaching the clamping body 2, as Figures 7-8 shown, each of the clamping bodies 2 is detachably connected to the driving cylinder 3, and the clamping bodies 2 are symmetrical after being detached from the driving cylinder 3. The clamping bodies 2 are movably clamped on the titanium forging. When the clamping body 2 is connected to the driving cylinder 3, the driving cylinder 3 can drive the clamping body 2 to clamp the end of the forging, drive the movement of the forging and its detachment from the forging press. When the clamping body 2 is detached from the driving cylinder 3, the clamping body 2 movably clamps the forging. When the forging deforms, the clamping body 2 deforms along with it under the action of clamping the forging, thereby solving the hard force exerted on the clamping body 2 by the forging deformation and the damage caused to the driving cylinder 3.

[0025] Specifically, as Figure 7As shown, a detachable hinge rod 4 is inserted through the hinge joint between the driving cylinder 3 and the clamping body 2, and a disassembly hole (not marked in the figure) for inserting the hinge rod 4 is formed in the clamping sleeve 1. Before forging, first insert the hinge rod 4 into the inner cavity of the clamping sleeve 1 through the disassembly hole of the clamping sleeve 1, and realize the hinge connection between the clamping body 2 and the driving cylinder 3 (the end of the clamping body 2 and the piston end of the driving cylinder 2 also have perforations for inserting the hinge rod, not marked in the figure). Then, the driving cylinder 3 can directly drive the clamping body 2 to rotate, clamp the forging, and shift one end of the forging onto the lower die of the forging press. Next, pull out the hinge rod 4 to realize the disassembly of the clamping body 2 and the driving cylinder 3. Preferably, to prevent the forging on this side from falling, a supporting plate 23 is preferably arranged inside the clamping body 2 to support this side of the forging.

[0026] After the disassembly of the clamping body 2 and the driving cylinder 3 is realized as described above, to realize the movable clamping of the forging, as Figures 7-8 shown, a limiting protrusion 21 is arranged inside the symmetric clamping body 2, and a compression spring 5 is movably sleeved on the limiting protrusion 21. After the hinge rod 4 is pulled out as described above, the compression spring 5 drives the two clamping bodies 2 to movably clamp the end of the forging. When the forging deforms near the clamping body 2 subsequently, the deformation force further squeezes the compression spring 5 through the clamping body 2, causing the clamping body 2 to deflect along with the deformation of the forging, while still maintaining the clamping effect on the forging, that is, overcoming the hard force transmitted by the deformation of the forging to the clamping body 2. When the forging is completed, drive the driving cylinder 3 to hinge and rotate so that it corresponds to the perforation of the hinge rod 4 of the clamping body 2, and then insert the hinge rod 4. By the action of the driving cylinder 3, the forged forging can be rigidly clamped and separated from the forging press.

[0027] Since the forging is forged step by step along the whole length, there will be relative sliding during the process of pushing the forging by the clamping body 2. Therefore, to solve this problem, as Figure 9 shown, driving protrusions 22 in contact with the end of the titanium forging are arranged inside the symmetric clamping body 2. The driving protrusions 22 abut against the side end face of the forging, and thus the relative sliding problem between the forging and the clamping body 2 can be solved during the movement process.

[0028] The principle of this application is as follows: During forging operations, the driving cylinder 3 drives the symmetrical clamping bodies 2 to rotate in a hinged manner and towards each other, clamping one end of the forging. Then, the other end of the forging is placed and supported on the lower die of the forging press. Subsequently, the articulated rod 4 is pulled out to disassemble the clamping body 2 from the driving cylinder 3. The forging on this side is supported by the supporting plate. At the same time, the acting force of the compression spring 5 drives the clamping bodies 2 on both sides to clamp the end of the forging movably. Then, the forging is moved by the overall horizontal movement trend of the clamping sleeve 1 to perform intermittent forging operations with the upper and lower dies of the forging press. When the forging deforms near the clamping body 2 in the subsequent process, the deformation acting force further squeezes the compression spring 5 through the clamping body 2, causing the clamping body 2 to deflect along with the deformation of the forging while still maintaining the clamping effect on the forging, that is, overcoming the rigid acting force transmitted by the deformation of the forging to the clamping body 2. When forging is completed, the driving cylinder 3 is driven to rotate in a hinged manner so that it corresponds to the perforation of the articulated rod 4 of the clamping body 2. Subsequently, the articulated rod 4 is inserted. By the action of the driving cylinder 3, the forged forging can be rigidly clamped and separated from the forging press.

[0029] The above shows and describes the basic principle, main features, and advantages of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed.
