Description

Technical Field

[0001] This utility model relates to the technical field of machining, and in particular to a forging clamping device for forging processing. Background Technology

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing them to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions. Forging can eliminate defects such as casting porosity generated during the smelting process, optimize the microstructure, and because it preserves complete metal flow lines, the mechanical properties of forgings are generally superior to those of castings made of the same material.

[0003] Forging is mostly done mechanically, but for some high-precision forgings, workers need to manually forge the hot billet using clamps. In manual forging, operators typically use clamps to hold the hot billet. Existing clamps are generally simple and fixed in structure, lacking good support points and relying entirely on manual support, making them laborious to use. Furthermore, during forging, the clamps need to be manually flipped and rotated to adjust the forging position. However, existing clamps already require considerable force to hold the forging, so flipping and rotating it requires even more force. This results in high workload, time-consuming, labor-intensive operations, and inconvenient operation, potentially leading to a decline in casting quality. Utility Model Content

[0032] Example 1

[0033] Reference Figure 1 This is the first embodiment of the present invention, which provides a forging clamping device for forging processing. This forging clamping device includes a clamping unit 100, which includes a jaw 101. A threaded rod 102 is fixedly installed behind the jaw 101. The threaded rod 102 is fixedly installed inside the central shaft 103. The central shaft 103 has a thread 104 in the middle section and passes through the center of the rotating ring 105.

[0034] The support unit 200 includes a rotating seat 201 installed on the outside of the rotating ring 105, a support platform 202 provided below the rotating seat 201, a support threaded rod 203 provided at the geometric center below the support platform 202, a threaded cylinder 204 fixedly installed on the outside of the support threaded rod 203, a base 205 provided at the bottom of the threaded cylinder 204, two support rods 206 symmetrically arranged above the base 205, and a control panel 207 fixedly installed on the top of the threaded cylinder 204.

[0035] The moving unit 300 includes casters 301 fixedly installed below the base 205.

[0036] The device is movable via the base 205 and casters, making it flexible in use. Rotating the threaded rod 102 extends it outward along the central shaft 103, pushing the jaws outward to clamp the forging. The forging can be clamped by retracting the threaded rod 102, depending on its size, making the device suitable for clamping forgings of different shapes and sizes. The central shaft 103 is supported by a steering seat, allowing it to bear force using the rotating seat 201 as a fulcrum when clamping the forging, making clamping more convenient and labor-saving. The central shaft 103 rotates within the rotating ring 105 via the central thread 104. The rotating ring 105, in conjunction with the central shaft 103, allows the entire clamping unit to rotate, facilitating the flipping of forgings during forging to adjust their forging surface. The height of the support platform 202 can be adjusted by the control panel 207, making the device suitable for forging needs of different heights, thus improving the applicability of the clamping device. Furthermore, the adjustment is made by threaded transmission, which provides good stability and makes operation more convenient.

[0037] Example 2

[0038] Reference Figures 2-4This is the second embodiment of the present invention, which differs from the first embodiment in that: a first operating disk 106a is provided at the end of the central shaft 103, a second operating disk 106b is provided at the end of the threaded rod 102, grippers 101 are symmetrically mounted on the first connecting platform 107a, and a clamping block 108 is provided at the top of the grippers 101. A first through hole 109a is provided at the geometric center of the first connecting platform 107a, and two second through holes 109b are symmetrically provided outside the first through hole 109a. The threaded rod 102 passes through the first through hole 109a, and the top of the threaded rod 102 is fixedly connected to the second connecting platform 107b. A limit rod 110 is provided below the second connecting platform 107b, and the limit rod 110 passes through the second through hole 109b. The gripper 101 has a third through hole 109c at its bottom end. The first connecting platform 107a has a first fixing ring 111a corresponding to the third through hole 109c. A first pin 112a is fitted between the third through hole 109c and the first fixing ring 111a. The second connecting platform 107b is connected to the middle of the gripper 101 via a connecting rod 113. The connecting rod 113 has fourth through holes 109d at both ends. The gripper 101 has a second fixing ring 111b corresponding to the fourth through hole 109d. The second connecting platform has a third fixing ring 111c corresponding to the fourth through hole 109d. A second pin 112b is fitted between the fourth through hole 109d, the second fixing ring 111b, and the third fixing ring 111c.

[0039] The threaded rod 102 is fixed at its top end below the second connecting platform 107b. The movement of the second connecting platform 107b controls the swing of the connecting rod 113. The forward and backward movement of the threaded rod 102 is controlled by rotating the second control panel 106b. When the threaded rod 102 moves forward, the second connecting platform 107b moves forward together, causing the connecting rod 113 to open and controlling the gripper 101 to open. Conversely, when the threaded rod 102 moves backward, the gripper 101 is controlled to close. The gripping state of the gripper 101 on the forging is controlled by rotating the threaded rod 102, so that the gripping device does not need to rely on manual gripping when gripping the forging, making the operation more convenient and labor-saving. At the same time, it improves the stability of the device when gripping the forging. The threaded rod 102 is moved by the threaded transmission to control the opening and closing of the gripper 101. Meanwhile, the anti-slip texture on the clamping block 108 makes the gripper 101 more secure and stable when gripping the forging. To prevent the gripper 101 from jamming, the bottom surface of the limiting rod 110 contacts the top surface of the first limiting platform 114a, forming a maximum limit. The limiting platform restricts the movement range of the central shaft 103 as it rotates within the rotating ring 105 via the central thread 104. The central shaft 103 controls the rotation of the gripper 101 and the forward / backward movement of the clamping unit through threaded transmission. Rotation of the first control disc controls the rotation of the central shaft, making the rotation of the gripper 101 more stable and preventing issues such as the lower device being too large to fit into the machine or insufficient clamping distance of the gripper 101 on the forging.

[0040] The remaining structure is the same as that in Example 1.

[0041] Example 3

[0042] Reference Figure 5 , Figure 6This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: a limiting block 208 is provided on the rotating seat 201 at a position corresponding to the groove 115; an installation groove 209 is provided on the rotating seat 201 to mate with the outer side of the rotating ring 105; a rotating disk 210 is provided below the rotating seat 201; first threaded holes 211a are provided on the front and rear outer sides of the rotating seat 201; a second threaded hole 211b is provided on the rotating ring 105 at a position corresponding to the first threaded hole 211a; and screws 212 are provided in the first threaded hole 211a and the second threaded hole. A rotating groove 213 is provided at the geometric center above the support platform 202; a rotating shaft 214 is provided on the rotating disk 210 at a position corresponding to the rotating groove 213; and a first bearing 215a is fixedly installed within the space formed by the rotating groove 213 and the rotating shaft 214. The support platform 202 has Z-shaped fixing blocks 216 on both sides. A third threaded hole 211c is opened on both sides of the support platform 202. A fourth threaded hole 211d is opened on the Z-shaped fixing block 216 at a position corresponding to the third threaded hole 211c. Screws 212 are installed in the third threaded hole 211c and the fourth threaded hole 211d. The rotating disk 210 is fixedly connected to the support platform 202 via the Z-shaped fixing blocks 216. A support sleeve 217 is slidably connected to the outer wall of the support rod 206. A first limiting ring 218a is provided at the upper end of the control disk 207, and a second limiting ring 218b is provided at the lower end of the control disk 207. The first limiting ring 218a is fixedly connected to the support sleeve 217 via connecting posts 219 on both sides. The second limiting ring 218b is fixedly connected to the top of the threaded cylinder 204. A second bearing 215b is fixedly installed inside the limiting ring 218a. A third operating disk 106c is fixedly installed in the middle of the control disk 207.

[0043] The groove 115 cooperates with the limiting block 208 to fix the rotating ring 105 inside the mounting groove 209. The screw 212 makes the limiting of the rotating ring 105 more stable and prevents shaking during use. The clamping unit can be disassembled and used separately, making it suitable for different forging environments and more functional. The support platform 202 and the rotating disk 210 are connected by the first bearing 215a, allowing the rotating disk 210 to rotate around the geometric center of the support platform 202, which facilitates the worker to turn during the movement of the forging. The "Z"-shaped fixing block 216 fixes the rotating disk 210 without affecting the rotation. When the third control panel 106c is rotated, the control panel 207, which is fixedly connected to the third control panel 106c, rotates together. The first limit ring 218a is fixedly connected to the threaded cylinder 204 as one unit. The first limit ring 218a and the second limit ring 218b fix the control panel 207 in a fixed position and prevent it from moving up and down. The first limit ring 218a and the second limit ring 218b are connected to the control panel through the second bearing 215b. Therefore, when the control panel is rotated, the threaded transmission controls the support threaded rod 203 to move up and down, thereby controlling the support platform 202 to move up and down. This allows for clamping of forgings placed at different heights, and at the same time, it enables the device to be suitable for forging needs at different heights.

[0044] The remaining structure is the same as that in Example 2.

[0045] Example 4

[0046] Reference Figure 1 , Figure 2 and Figure 7This is the fourth embodiment of the present invention. This embodiment differs from the third embodiment in that: when using the device, the clamping device is moved to the working position, and the third operating disk 106c is rotated to drive the control disk 207 to rotate, which in turn drives the support threaded rod 203 to rotate. When the control disk 207 rotates, it engages in threaded transmission with the support threaded rod 203. Then, with the assistance of the support rod 206, the support platform 202 is raised. After the support platform 202 rises to a suitable position, the rotation of the third operating disk 106c is stopped. Then, the device is used to clamp the forging. When clamping the forging, the second operating disk 106b is rotated, and the control threaded rod 102 rotates... The second connecting plates are connected by a threaded drive, so that with the assistance of the sliding rod, the threaded rod 102 drives the second connecting platform 107b to move towards the first connecting platform 107a. When the second connecting platform 107b moves, it pulls the two connecting rods 113 to drive the jaws 101 to rotate towards the center. The forging is clamped by the clamping blocks 108 on the jaws 101. Rotating the second control disk 106b drives the threaded rod 102 to rotate. The rotation stops after the forging is stably clamped. During the processing, the clamping unit can be rotated by rotating the first control disk 106a, thereby driving the forging to rotate. The forging can be forged at multiple angles, which is convenient and labor-saving. When the support platform 202 is not needed, first rotate the rotating ring 105 to be close to the first limiting platform 114a, then remove the screws 212 on the limiting block 208 of the rotating seat 201. After that, the clamping unit can be pushed out of the rotating seat 201 and used independently. When the support platform 202 is needed, directly align the limiting block 208 on the rotating seat 201 with the groove 115 on the rotating ring 105. The rotating ring 105 is pushed into the rotating seat 201 through the mounting groove 209 and then fixed with screws 212 to form a stable limit. This completes the installation between the clamping unit and the rotating seat 201, enabling the device to meet more forging needs and has good applicability.

[0047] The remaining structure is the same as that in Example 3.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
