Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and more specifically, it relates to a shifting device for die forging. Background Technology

[0002] In the die forging process, the workpiece needs to be processed into the target shape through multiple forming processes. Different processes usually correspond to different forming grooves on the die. Therefore, it is necessary to accurately transfer the intermediate billet after completing the previous process to the forming groove of the next process. This transfer process directly affects production efficiency and product accuracy. At present, the mainstream transfer methods in the industry have two main problems: First, some small and medium-sized die forging equipment still rely on manual operation. Workers need to use pliers and other tools to reach into the equipment to pick up the intermediate billet and then transfer it to the next station. This not only requires frequent adjustment of the billet position to ensure alignment with the forming groove, but also makes the operation cumbersome and time-consuming, significantly reducing the production cycle. At the same time, the high temperature of the billet also poses a safety hazard of burning workers. Second, although some highly automated equipment uses robotic arms for transfer, the robotic arms have complex structures and high costs. When dealing with billets with protruding bar structures, special fixtures need to be designed to prevent the billet from slipping or shifting position, resulting in poor adaptability. In addition, the long movement path of the robotic arm further increases the transfer time, making it difficult to meet the needs of efficient die forging production. Therefore, there is an urgent need for a die forging positioning device that is simple in structure, easy to operate, and adaptable to bar-shaped billets, in order to solve the problems of low efficiency, poor safety, and insufficient adaptability of existing positioning methods, resulting in unsatisfactory overall performance. Accordingly, this invention proposes a positioning device for die forging. Utility Model Content

[0013] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0014] Example 1 See Figures 1 to 4As shown, the forging positioning device involved in this embodiment includes a lower die 1. The lower die 1 is provided with a front forming groove 2 arranged on the left and a rear forming groove 3 arranged on the right.

One end of the rear lifting groove 5 is connected to the rear forming groove and the other end is connected to the outside. The front and rear sides of the lower die 1 are respectively... The device includes a front lifting plate 6 and a rear lifting plate 7 that slide up and down relative to each other. The tops of both the rear lifting plate 7 and the front lifting plate 6 have movable slopes that are higher on the left and lower on the right. The front lifting plate 6 is located below the front lifting groove 4, and the rear lifting plate 7 is located below the rear lifting groove 5. A transition plate 8, which is fixed to the lower pressing mold, is provided between the front lifting plate 6 and the rear lifting plate 7. The top of the transition plate 8 has a fixed slope that is higher on the left and lower on the right. The fixed slope is higher than the front lifting groove and the rear lifting groove. The device also includes a linear reciprocating motion mechanism for controlling the up and down movement of the front lifting plate and the rear lifting plate.

[0015] Furthermore, the linear reciprocating motion mechanism includes a front drive hole 9 and a rear drive hole 10 formed on the lower die 1.

A rear drive rod 12 with both ends extending out of the hole is provided in the rear drive hole 10, and the rear drive rod 12 is slidably connected in the rear drive hole 10. The front drive hole 9 is located below the front forming groove, and the rear drive hole 10 is located in the rear forming groove. Below, the lower pressing mold 1 is also provided with push-pull holes 13 that extend to the left and right and are respectively connected to the front transmission hole and the rear transmission hole. A push-pull rod 14 is slidably connected in the push-pull hole 13. One end of the push-pull rod 14 is connected to a push rod cylinder 15 that controls its movement. The push rod cylinder 15 is fixed on the lower pressing mold 1. The front lifting plate 6 is provided with a front guide hole 16 that extends to the left and right at an angle.

[0017] In this implementation scheme, the hot-pressed blank with protruding rods is first placed into the front forming groove of the lower die, with the rod-shaped portion of the blank extending into the front and rear pushing grooves on both sides. The linear reciprocating motion mechanism is activated to control the front pushing plate to slide upward, and its movable slope, which is higher on the left and lower on the right, lifts the blank. The blank rolls upward along the slope and transitions to the fixed slope of the transition plate. The blank continues to roll to the right along the fixed slope, while the linear reciprocating motion mechanism controls the rear pushing plate to slide upward. The movable slope of the rear pushing plate receives the blank and assists it in rolling to the rear forming groove. Finally, the worker uses pliers to slightly correct the position of the blank, completing one repositioning operation. Then, the front and rear pushing plates are reset under the action of the linear reciprocating motion mechanism, waiting for the next repositioning operation.

[0021] In this embodiment, a baffle 19 with its top higher than the front push groove 4 is provided to block the raised intermediate product on the right side.

[0022] The forging transfer device involved in this utility model utilizes the inherent rod-like structure and sloping surface of the billet to achieve automatic rolling transfer of the billet, eliminating the need for complex operations, shortening transfer time, and reducing equipment costs and maintenance difficulty. Furthermore, workers do not need to come into close contact with the high-temperature billet, reducing the risk of burns. The continuous sloping surface guide prevents the billet from shifting and slipping, reducing product scrap rate, ensuring production quality, and has complete overall functions and strong practicality.
