Description

Technical Field

[0001] The utility model relates to the technical field of air hammers, in particular to an air hammer for forging parts processing with a flipping component. Background Technique

[0002] An air hammer is a type of free forging equipment. The compression cylinder compresses air, which is sent into the working cylinder through a distribution valve to push the piston and the hammer head to move up and down for hammering. It is flexible in operation and is suitable for various free forging operations, such as stretching, upsetting, punching, shearing, forging welding, twisting, bending, etc. Various open-die forging can be carried out using a pad die.

[0003] Publication No. CN216680031U discloses an air hammer for forging parts processing with a flipping structure.

[0036] The driving mechanism 2 includes a base 201. One side of the top of the base 201 is connected with an air hammer body 202. One surface of one side of the air hammer body 202 is adhesively connected with a workpiece 203. One end of the workpiece 203 is adhesively connected with the toothed plate 114. One end of the base 201 away from the air hammer body 202 is fixedly connected with a driving motor 204. The driving motor 204 drives a threaded rod 205 to rotate;

[0037] The output end of the driving motor 204 penetrates through the base 201 and is fixedly connected with a threaded rod 205. One end of the threaded rod 205 away from the driving motor 204 is rotatably connected with the base 201. The outer side of the threaded rod 205 is threadedly connected with a threaded sleeve 206.

[0039] Working principle: Before using an air hammer for forging parts processing with a flipping component, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 6 As shown, first adjust the height of the clamping block 113 according to the size of the workpiece 203 to align it with the position of the central axis of the workpiece 203. Then start the cylinder 110 to drive the slider 111 to move outside the support frame 109, thereby driving the first connecting rod 112 to rotate around the slider 111 and the clamping block 113. By using the limit of the second connecting rod 115 on the clamping block 113, the relative movement of the two clamping blocks 113 can be realized to clamp the workpiece 203.

[0040] Secondly, start the air hammer body 202 to hammer the workpiece 203. When it is necessary to flip the workpiece 203, start the electric telescopic rod 102 to drive the rack 103 to move up and down. By using the meshing effect between the rack 103 and the gear 105, the roller 106 is driven to rotate. By using the synchronous effect of the belt 107, the cylinder 108 and the roller 106 are driven to rotate together. By driving the clamping block 113 to rotate through the cylinder 108, the flipping of the workpiece 203 can be realized.

[0041] Finally, when it is necessary to change the position of the workpiece 203, start the driving motor 204 to drive the threaded rod 205 to rotate. By using the threaded effect between the threaded rod 205 and the threaded sleeve 206, the fixed sleeve 207 has a tendency to rotate. By using the limiting effect of the guide rod 208 on the fixed sleeve 206, the support rod 209 is driven to move along the horizontal direction of the guide rod 208, and thus the workpiece 203 can be driven to move.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
