[0002] At present, in the forging industry, long shaft fork type forgings are various, but in many cases, other dimensions of forgings are basically consistent, and only the length of the rod part is different; if all are forged separately, regardless of the difficulty in process, only the mold cost and material waste are a huge consumption. Through communication with customers, it is known that customers only have requirements for the head strength of long shaft fork type forgings, and the rod part can meet the basic performance requirements of the material quality; based on this, the local heating forging process is currently used to complete the shaping of the head, but the lengths of long shaft forks are different.
[0003] For such fork type special-shaped forgings, the current process route is: blanking - local heating - upsetting - pre-forging - final forging - edge cutting - heat treatment - shot blasting - sawing - inspection - warehousing; among them, the sawing process, due to the local heating forging process of forgings, leads to different product lengths, which cannot be accurately controlled, and the sawing length must be determined after measuring; the subsequent inspection also needs to be fully inspected to ensure the product quality, which is a huge workload and greatly wastes manpower and material resources. And the positioning of the blank in the cavity is by the small step at the front end of the cavity (the blank is positioned by the front end of the step), which cannot accurately grasp the distance for workers, and requires certain operation experience for workers, and inaccurate positioning has a great influence on the fork head forming, and even causes the blank to be scrapped, and also affects the total length of the long shaft fork.

DETAILED DESCRIPTION
[0019] The embodiment of the utility model will be described in detail below with the drawings and examples, by which the realization process that the utility model applies technical means to solve technical problems and achieves technical effects can be fully understood and implemented.
[0020] As shown in the figure, the long shaft fork type forging saw-free total length control device provided by the embodiment includes a lower die seat 1 and a lower die cavity 2 arranged above the lower die seat 1, and the lower die cavity 2 is provided with a pre-forging die cavity 3 and a finish forging die cavity 4. A positioning device is arranged on one side of the finish forging die cavity 4, and the positioning device includes a bracket 5 and a limiting mechanism. The lower die seat 1 is provided with a fixed seat 6, and the bracket 5 is arranged on the fixed seat 6. Two first buffer springs 7 are arranged between the bracket 5 and the fixed seat 6. When the upper die is closed during forging, the first buffer spring 7 plays a buffering role on the blank 0, preventing the rod part of the blank from being deformed due to pressure.
[0021] The top of the bracket 5 is provided with a circular arc surface matching the shape of the blank. The limiting mechanism includes a sliding slot 8 and a positioning block 9 arranged in the sliding slot 8. The finish forging die cavity 4, the bracket 5 and the sliding slot 8 are arranged on the same horizontal line, so that the head of the blank 0 abuts against the end face of the finish forging die cavity 4, and the tail abuts against the positioning block 9. The outer side of the positioning block 9 is provided with a limiting plate 10. The limiting plate 10 and the positioning block 9 are connected by an adjusting bolt 11. A second buffer spring 12 is arranged between the limiting plate 10 and the positioning block 9. The second buffer spring 12 is sleeved on the adjusting bolt 11. The arrangement of the second spring 12 can reduce the rigidity of the connection between the positioning block 9 and the limiting plate 10, avoiding the breakage of the blank. One side of the lower die seat 1 is provided with a mounting seat 13, and the sliding slot 8 and the limiting plate 10 are arranged on the mounting seat 13.
[0022] The working principle of the long-shaft fork type forging free sawing total length control device provided by the embodiment is as follows: according to the length of the long-shaft fork blank after heading, a positioning block 9 with a corresponding thickness is selected and installed, and after being positioned at a suitable position, the positioning block 9 is locked and fixed by adjusting the bolt 11. The blank after heading is placed on the surface of the final forging die cavity 4, and the blank needs to be leveled by the bracket 5. The end of the blank 0 abuts against the end of the final forging die cavity, and the tail of the blank abuts against the positioning block 9, so that the stability of the blank 0 in the length direction of the die cavity position is ensured, and then the blank is forged and formed. The positioning of the blank in the pre-forging cavity is solved, and the positioning is not accurate. The positioning block 9 is positioned by the small step at the front end of the pre-forging cavity (the front end of the blank abuts against the step to complete the positioning). After the free sawing total length control device of the embodiment is used, the front end is no longer positioned, but the rear end is positioned. Workers are easier to observe, the operation is simple, the positioning is more reliable, the position of the blank in the cavity can be controlled in a stable range, the total length of the long-shaft fork is ensured to be within the tolerance of ±3mm, and after the device is used, a sawing process can be reduced. The stability of the process is improved due to the change of the positioning mode, and the qualified rate is further improved.
