Description

Technical Field

[0001] The invention relates to the technical field of precision forging machine push head repair equipment, in particular to a hammering device for removing weld layer stress. Background Art

[0002] The working hammerhead of a precision forging machine is subject to high-frequency, high-intensity impact loads. Consequently, the contact area between the hammerhead and the forging (the top of the hammerhead) often suffers from severe impact, resulting in localized dents, cracks, or uneven surfaces. These dents can severely impact the efficiency of the precision forging machine and the quality of the forged parts. Furthermore, the hammerhead's use of specialized steel contributes to its high production cost. Discarding a hammerhead with localized dents or cracks would be a significant waste of resources.

[0003] For these reasons, and in line with the principles of cost-saving and waste recycling, the damaged parts of the "precision forging hammer" are repaired with welding and reused. During the welding repair process, the entire damaged surface of the "precision forging hammer" is first removed by lathe turning (for multiple purposes: 1. To avoid deep cracks; 2. To ensure balanced strength and flexibility at the "precision forging hammer"'s striking area through this integrated repair process) to form a "weld matrix." Then, argon arc surfacing is applied layer by layer to each surface of this "weld matrix" (the striking surface) until it is welded to the desired height, width, and thickness of the "precision forging hammer"'s striking area.

[0004] During the cladding modification process for the "precision forging machine hammer head," a "layer-by-layer stress relief method" was employed to maximize the removal of stress caused by welding. After workers welded the hammering area of ​​the "precision forging machine hammer head" to the specified number of layers (one or more) as per design requirements, they then used hand or electric hammering to stress-relieve the multiple layers. The disadvantages of this method include: lack of professionalism, high labor intensity, uneven striking, inability to effectively guarantee stress relief, and certain safety risks.

The pin has a thin column structure 242 with different diameters. 3 and the thick column structure 2424, pulling the handle 2421 can adjust the thin column structure 2423 and the thick column structure 2424 to respectively penetrate into the through hole 243; an anti-slip groove is provided on the hammer head 226, and when the thick column structure 2424 enters the through hole 243, the thick column structure 2424 is snapped into the anti-slip groove, and the thick column structure 2424 can be snapped into the anti-slip groove and the hammer head positioning seat 241, thereby limiting the movement of the hammer head 226, and when the thin column structure 2423 enters the through hole 243, the thin column structure 2423 cannot be snapped into the anti-slip groove, thereby failing to limit the movement of the hammer head 226, and the hammer head 226 can be plugged in and out for replacement.

[0094] Specifically, the clamping device 24 also includes an anti-slip expansion pin 244, which is sleeved on the pin column and arranged in the hammer head anti-slip bracket 242 to fill the gap between the hammer head anti-slip bracket 242 and the pin column, and can prevent the hammer head anti-slip bracket 242 from sliding out of the hammer head positioning seat 241.

[0095] Specifically, the clamping device 24 also includes: an elastic reset member 245 and an elastic reset member anti-slip nut 246. The elastic reset member 245 is sleeved on the pin and arranged outside the hammer head anti-slip bracket 242. One end of the elastic reset member 245 abuts against the hammer head anti-slip bracket 242; the end of the pin is provided with a thread, and the elastic reset member anti-slip nut 246 cooperates with the thread, and the other end of the elastic reset member 245 abuts against the elastic reset member anti-slip nut 246.

[0096] Reference Figure 16 and Figure 17 As shown, the process of locking and quickly replacing the hammer head 226 is as follows: the elastic reset member 245 is set to always pull the hammer head anti-detachment bracket 242, so that the thick column structure 2424 in the hammer head anti-detachment bracket 242 is always located in the through hole 243, thereby achieving locking of the hammer head 226; only when the hammer head 226 needs to be replaced, the hammer head anti-detachment bracket 242 is pulled to make the thin column structure 2423 in the hammer head anti-detachment bracket 242 enter the through hole 243, and the hammer head 226 can be pulled to be taken out and replaced. At this time, the elastic reset member 245 is compressed under the drive of external pulling. After the hammer head 226 is replaced, when no external force is applied, the elastic reset member 245 elastically resets, and the thick column structure 2424 in the hammer head anti-detachment bracket 242 is located in the through hole 243, thereby achieving locking of the hammer head 226.

[0097] Reference Figure 18 As shown, the protective cover assembly 25 includes: a transmission member protective cover body 251 and a flywheel protective cover body 252. The transmission member protective cover body 251 and the flywheel protective cover body 252 are arranged on both sides of the shell assembly 21, and are respectively covered outside the transmission member 222 and the flywheel 227; the protective cover assembly 25 also includes an adapter bracket 253 for connecting the transmission member protective cover body 251 and the shell assembly 21, and the flywheel protective cover body 252 and the shell assembly 21.
