Technical Field

[0001] The utility model relates to the technical field of forging processing, in particular to a clamping tool for forgings. Background Art

[0002] Forgings are workpieces or blanks obtained by forging and deforming metal billets. Forging is a processing method that uses forging machinery to apply pressure to metal billets to produce plastic deformation in order to obtain certain mechanical properties and obtain forgings of a certain shape and size. When forgings are processed, clamping tools are required to clamp them.

[0003] After searching, the patent number is CN204052764U, and the name is a utility model of a forging clamping device, including: through research and analysis, it is found that although it prevents workers from being burned by clamping forgings and improves the advantages of human health, it still has the following disadvantages to a certain extent.

[0004] For example, because it does not have the function of measuring the clamping force during use, when the clamping force of the forging is too large, it is easy to cause the forging to deform and damage the forging. In addition, it does not have a good clamping effect. Therefore, when clamping the forging, it cannot clamp the forging in the appropriate position, which easily causes the forging to slide during processing and affects the processing effect. In order to solve the above technical problems, we have designed a clamping tool for forgings. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model has the advantage of measuring the clamping force by cooperating with the clamping plate, the lower pressure plate, the long plate, the connecting plate, the pressure sensor, the first stabilizer bar and the second stabilizer bar. The hydraulic cylinder pushes the long plate to move so that the clamping plate can contact the forging, thereby clamping the forging. At the same time, the clamping force of the clamping plate on the forging is monitored by the pressure sensor thereon. When the appropriate pressure is reached, the hydraulic cylinder stops extending, and at the same time, the electric telescopic rod extends to push the connecting plate to move, so that the lower pressure plate descends to press the forging. The pressure applied by the lower pressure plate on the forging is monitored by the pressure sensor thereon, thereby controlling the clamping force on the forging and preventing the forging from deforming. When measuring force, the first stabilizer bar and the second stabilizer bar are used to ensure the stability of the clamping plate and the lower pressure plate, and also improve the clamping stability of the forging.

[0014] 2. The utility model has the advantage of good clamping effect through the cooperation of U-shaped frame, pull ring, moving rod, connecting spring, L-shaped positioning rod, circular plate, limit plate and electric telescopic rod. When clamping the forging, pull the pull ring to allow the moving rod to drive the circular plate to move upward, so that the connecting spring contracts and the L-shaped positioning rod moves out of the positioning groove, so that the limit plate can move, thereby adjusting the position of the electric telescopic rod, so that the electric telescopic rod is adjusted to a suitable position, so that the lower pressure plate can better press the surface of the forging, thereby improving the pressing effect on the forging. After the adjustment is completed, release the pull ring to reset the connecting spring, so that the L-shaped positioning rod can position the limit plate to prevent the limit plate from moving.
