[0018] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0019] Reference Figure 1 , which is a workpiece free forging precision forging platform disclosed in the present invention, includes a base 1, which is a supporting member and installation reference of the entire platform. The base 1 is in a rectangular shape, and a protective cover 11 is provided on the base 1. The protective cover 11 is hollow inside to form a forging cavity 12. The protective cover 11 and the base 1 are detachably connected or hinged to facilitate opening.

[0020] Reference Figure 2 The middle position of the upper end surface of the base 1 is the positioning part 13, which is used to fix the workpiece. The positioning part 13 is composed of a groove 131 formed by the depression of the upper end surface of the base 1 and a plurality of fixing parts 132. The fixing parts 132 can be cylinders, electric cylinders or screws, etc. The fixing parts 132 are used to fix the workpiece in the position of the groove 131. After the workpiece is fixed, the forging part 2 forges the workpiece. The forging part 2 has a plurality of forging heads 21, each of which can slide relative to the positioning part 13 and the forging head 212 of each forging head 21 is positioned toward the positioning part 13.

[0021] When forging the workpiece, forging is performed at different positions by using the forging heads 212, so that the workpiece does not need to be rotated multiple times, thereby reducing errors and tolerances caused by repositioning the workpiece.

[0022] Reference Figure 2Specifically but not limiting, the forging part 2 further includes a rotating rail 22, and the forging head 21 is slidably mounted on the rotating rail 22, wherein the rotating rail 22 is arc-shaped and the center of the circle is located at the position of the positioning part 13. A sliding groove 221 is opened on one side of the rotating rail 22 facing the positioning part 13, and the sliding groove 221 is used to mount the forging head 21.

[0023] Reference Figure 2 , Figure 3 as well as Figure 4 The forging head 21 includes a sliding portion, a telescopic portion 211 and a forging head 212. The sliding portion cooperates with the slide groove 221 and can slide in the slide groove 221. A locking plate 213 extends from the telescopic portion 211, and a locking member 214 is installed on the locking plate 213. Figure 3 In the illustrated embodiment, the locking member 214 is a bolt that penetrates the locking plate 213 . When the forging head 21 slides to the corresponding position, the forging head 21 is fixed by the locking member 214 .

[0024] At this time, the coverage of the forging position of the workpiece by the forging head 21 is the projection of the slide groove 221 of the rotating rail 22 on the workpiece. In order to further improve the coverage rate, the rotating rail 22 can be rotatably mounted on the base 1. Figure 2 as well as Figure 4 Specifically but not limited to, the base 1 is equipped with a rotating mechanism 3, and the rotating mechanism 3 includes a rotating link 31 and a telescopic link 32, wherein the rotating link 31 is rotatably installed on the base 1, the telescopic link 32 is relatively slidably connected to the rotating link 31, and one end of the telescopic link 32 away from the rotating link 31 is rotatably connected to the rotating rail 22. Specifically but not limited to, the rotating link 31 is rotatably connected to a rotating sleeve 33, and the rotating sleeve 33 is threadedly connected to the telescopic link 32.

[0025] During the forging process, by rotating the rotating rail 22, the forging head 21 can be slid to the forging position without adjusting the workpiece, thereby achieving forging of different angles of the workpiece. When the rotating rail 22 is rotated, by rotating the rotating sleeve 33, the rotating sleeve 33 drives the telescopic connecting rod 32 away from or close to the rotating connecting rod 31, thereby driving the rotating rail 22 to rotate.

[0026] The platform of the present invention also includes an auxiliary support mechanism 4, referring to Figure 2 as well as Figure 4 The auxiliary support mechanism 4 includes a support link 41 and a support slide bar 42 , wherein the support link 41 is slidably connected to the support slide bar 42 , the support link 41 is rotatably connected to the base 1 , and the support slide bar 42 is rotatably connected to the rotating rail 22 .

[0027] Reference Figure 4 as well as Figure 5The connection between the supporting link 41 and the supporting slide bar 42 has a damping part 43. Specifically but not limiting, the supporting link 41 is extended with an outer convex ring 431, and the outer convex ring 431 of the supporting slide bar 42 is extended with an inner protrusion 432, the outer convex ring 431 and the inner protrusion 432 are sealed, and the outer convex ring 431, the inner protrusion 432 and the air between the two form the damping part 43.

[0028] The auxiliary support mechanism 4 is used to auxiliary support the rotating part, and the torque of the auxiliary support mechanism 4 on the rotating mechanism 3 in the tilted state is shared, so as to extend the service life of the entire platform.

[0029] The present invention also provides a method for improving the accuracy of free forging of a workpiece, comprising: Step 1: Measure and calculate the workpiece to determine the forging position and forging sequence; Step 2: Place the workpiece on the positioning portion 13 and fix it; Step 3: According to the forging position and forging sequence determined in step 1, the position of the rotating rail 22 is adjusted, a corresponding number of forging heads 21 are installed on the rotating rail 22 and the forging heads 21 are adjusted to corresponding positions, and the workpiece is forged by the forging heads 21; Step 4: adjusting the position of the rotating rail 22, and then adjusting the position of the forging head 21, and forging the workpiece by the forging head 21; Step 5, repeating step 4 until all forgeable positions of the workpiece in this fixed state are forged; Step 6: Repeat steps 2 to 5 until the workpiece is completely forged.

[0030] The implementation principle of this embodiment is: By means of the rotatable rotating rail 22 and the forging heads 21 whose quantity and position can be adjusted on the rotating rail 22, it is possible to fix the workpiece once and then perform forging multiple times, thereby reducing the errors and tolerances caused by repositioning the workpiece.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
