Description

Technical Field

[0001] This utility model relates to the field of casting tool technology, specifically a split-type forging fixture. Background Technology

[0002] To shape forgings, they need to be heated and processed at high temperatures. To facilitate the movement of these high-temperature forgings, they need to be clamped using fixtures. Conventional fixtures are usually scissor clamps. Workers need to hold the handle of the fixture to clamp the forging, lift it, and move it. In this way, both hands need to maintain the clamping force and lift the forging, and it is very strenuous due to the lack of support points. However, if an electric clamping tool is used, it will increase the weight of the fixture, making it inconvenient to operate by hand. Utility Model Content

[0003] To address the problem of the excessive effort required to use scissor clamps in certain scenarios, this invention provides a split-type forging clamp.

[0004] The technical solution of this utility model is as follows: A split-type forging fixture, comprising: The clamping member includes a reference plate and a clamping claw disposed thereon, and the reference plate also has a guide ring disposed in the middle of the end of the clamping claw away from the clamping position; A gripping component, comprising a main rod detachably connected to a reference plate, wherein a handle and a grip are provided at the end of the main rod away from the reference plate; A tensioning component includes a pull rope, the end of which passes through a guide ring, splits, and connects to both ends of the gripper. A pull ring is provided at the end of the pull rope away from the gripper and is located near the handle. The pull ring can drive the pull rope to move and can pull the pull rope to close the gripper when it moves towards the end near the handle.

[0005] Based on the original scissor clamp, by adding a gripping part and a tensioning part, its usage can be changed. By using the tensioning part in conjunction with the gripping part to clamp the jaws with gripping force, the other hand can hold the handle to move the forging. In some scenarios, this usage method is more labor-saving than the direct scissor clamp.

[0006] To ensure a constant pull ring position, the main body rod is made of magnetic material, and a fixing seat is provided between the pull rope and the pull ring, with the fixing seat being a magnet.

[0007] As a preferred embodiment, the pull cord is detachably connected to the end of the gripper.

[0008] To be applicable to more scenarios, the clamping component is available in multiple models, and the specifications of the grippers of the multiple models are different.

[0009] In order to adjust the tensioning element, the fixing seat can be fixed at multiple positions along the length of the rope.

[0010] As a preferred embodiment, the handle is positioned above the clamping member.

[0011] To change the operating method, the main rod can rotate relative to the reference plate, and the plane of rotation is parallel to the plane of rotation of the gripper.

[0012] To facilitate the unfolding of the grippers, the ends of the grippers away from the guide ring are provided with beveled surfaces.

[0013] To facilitate automatic unfolding of the grippers, a torsion spring is provided at the rotation axis of the grippers.

[0014] For ease of placement, the lower surface of the reference plate is flat.

[0015] The beneficial effects of this utility model are as follows: This utility model is a split forging clamp. Based on the structure of the existing scissor clamp, by changing the length of its gripping part, and then by setting up a gripping component and a tensioning component, it is possible to clamp the forging by holding it with one hand. Then, the other hand can use the handle to hold and lift the forging. This method is more convenient to use in some scenarios than the method of clamping directly with a scissor clamp. In addition, this method can be adapted to more specifications and models by changing the clamping component. Attached Figure Description

Figure 1 (Different states); Figure 3 This is a side view of the structure of this utility model; Figure 4 This is a schematic diagram of the clamping component structure of this utility model; The components represented by the various reference numerals in the diagram are: 1. Clamping component; 11. Base plate; 12. Gripper; 13. Guide ring; 2. Holding component; 21. Main rod; 22. Handle; 23. Handle; 3. Tensioning component; 31. Pull rope; 32. Fixing base; 33. Pull ring. Detailed Implementation

[0018] Example 1 like Figure 1-3 The split-type forging fixture shown includes: Clamping member 1, the clamping member 1 includes a base plate 11 and a clamping jaw 12 disposed thereon, wherein, as Figure 3 As shown, for ease of placement, the lower surface of the reference plate 11 is flat and can be placed directly on the supporting surface. Then, the aforementioned gripper 12 is set to complete the clamping action. The structure of the gripper 12 will not be described in detail; it is sufficient to clamp the forging. It should be noted that, in order to facilitate the driving of the gripper 12, the reference plate 11 also has a guide ring 13 in the middle of the end of the gripper 12 away from the clamping position. The guide ring 13 needs to be used in conjunction with the tensioning member 3 to achieve the tightening action.

[0019] Subsequently, to facilitate gripping from a distance, a gripping component 2 is also required. The gripping component 2 includes a main body rod 21 detachably connected to the reference plate 11. The end of the main body rod 21 away from the reference plate 11 is provided with a handle 22 and a handle 23. The handle 22 can be directly gripped by one hand of the operator, and the handle 23 can also be gripped. Therefore, the gripping action at the above two positions can achieve the clamping and moving effect of the forging. However, unlike scissor clamps, the two hands do not need to provide clamping force to maintain the clamping of the forging, but only need to provide lifting force. Furthermore, the position of the handle 23 of the handle 22 can be set according to the actual needs of the operator. With the above structure alone, there is a lack of clamping force for the forging. Therefore, based on this, further...

[0020] A tensioning component 3 is also required, which includes a pull rope 31. The end of the pull rope 31 passes through the guide ring 13, splits, and connects to both ends of the gripper 12. Therefore, during the movement of the pull rope 31, it is guided and tightened by the guide ring 13, allowing it to move as expected. Figure 1 As shown in Figure 2, the state of the gripper 12 changes, and a pull ring 33 is provided at the end of the pull rope 31 away from the gripper 12 and near the handle 23. Therefore, during use, the pull rope 31 needs to be moved towards the handle 23. In order to facilitate pulling the pull rope 31, the operator can hold the pull ring 33 and move the pull rope 31. When moving towards the end near the handle 23, the pull rope 31 can be pulled to close the gripper 12. Therefore, in the initial state, the pull ring 33 does not contact the handle 23 and is spaced apart to ensure that there is enough space for the pull ring 33 to reach the preset position and be held in conjunction with the handle 23. The space for movement, i.e. the spacing, can drive the gripper 12 to complete the clamping action. In this way, the gripper 12 can be driven by a single hand grip. Therefore, based on this, the above structure can be used as long as the grip strength is sufficient to tighten the pull rope 31.

[0021] Based on this, by adding a gripper 2 and a tensioner 3 to the original scissor clamp, its usage can be changed. By using the tensioner 3 in conjunction with the gripper 2 to clamp the jaws 12 with gripping force, the other hand can hold the handle 23 to move the forging. In some scenarios, this usage is more labor-saving than the direct scissor clamp. Since the scissor clamp provides clamping force while also lifting the forging based on the end of the clamp, it requires a lot of arm strength. However, by using gripping force to achieve clamping and lifting with both hands, and with the handle as a support, the lifting action is improved compared to before, and it is more in line with the usage requirements.

[0022] Furthermore, in the above structure, to ensure the pull ring 33 remains in a constant position, the main body rod 21 is made of magnetic material, and a fixing seat 32, which is a magnet, is provided between the pull rope 31 and the pull ring 33. Without human intervention, the pull ring 33 can maintain a constant position, making it more convenient to use. Moreover, the magnetic attraction method does not cause significant resistance during the opening and closing of the gripper 12, thus not affecting its use.

[0023] Furthermore, to accommodate the usage habits of more workers and to allow for adjustment of the tensioning component 3, the fixing base 32 can be fixed at multiple positions along the length of the pull rope 31. During use, the position of the pull ring can be determined by adjusting the position of the fixing base 32 relative to the pull rope 31, allowing workers to simultaneously hold both components when clamping the forging. Additionally, the handle 23 is positioned higher than the clamping component 1.

[0024] Example 2 like Figure 4 As shown, to accommodate forgings of more specifications, the pull rope 31 is detachably connected to the end of the gripper 12. Therefore, to suit more applications, the clamping member 1 is available in multiple models, each with different specifications for its gripper 12. During use, it can be disassembled and replaced as needed, and the position of the fixing seat 32 on the tensioning member 3 relative to the pull rope 31 can be adjusted to meet specific usage requirements.

[0025] Furthermore, to change the operating method, the main rod 21 can rotate relative to the reference plate 11, and the plane of rotation is parallel to the plane of rotation of the gripper 12. During use, the aforementioned angle can be adjusted according to the operator's working position.

[0026] Example 3 To facilitate the unfolding of the gripper 12, the end of the gripper 12 away from the guide ring 13 is provided with a chamfered surface. In use, as... Figure 4As shown, the inclined surface is used for guidance, which facilitates the separation of the clamping jaws 12 through the forging, so that they are spread out and the clamping action can be easily completed.

[0027] Example 4 In addition to the method disclosed in Embodiment 3, a torsion spring is provided at the rotation axis of the gripper 12 to facilitate automatic unfolding of the gripper 12.
