Description

Technical Field

[0001] This invention relates to forging technology, specifically to a multi-directional forging equipment and forging method. Background Technology

[0002] The forging of a product requires several processes, generally including pre-forging and final forging. Pre-forging is completed by a pre-forging die in conjunction with a multi-directional forging machine, and final forging is completed by a final forging die in conjunction with a multi-directional forging machine. If there are two multi-directional forging machines, each can complete one tooling operation. If there is only one multi-directional forging machine (we will not consider the case where a multi-directional forging machine is equipped with two sets of forging structures, as it is essentially still two multi-directional forging machines), it is necessary to switch between the pre-forging die and the final forging die. Currently, the switching is generally done manually (especially for large products, where the pre-forging die and the final forging die are relatively heavy, and lifting machinery is required during the switching process), which is time-consuming, labor-intensive, and inefficient. However, there are also cases where it is not necessary to switch forging dies, mainly for small products. In these cases, the upper die of the pre-forging die and the final forging die share an upper template, the lower die shares a lower die base, and the left die shares a left template and a right template. Summary of the Invention

[0003] In view of the above problems, the present invention proposes a multi-directional forging equipment and a forging method.

[0004] The technical solution of this invention: A multi-directional forging apparatus includes forging dies and a multi-directional forging machine. Each forging die consists of an upper die, a lower die, a left die, and a right die. The multi-directional forging machine has an upper template, a lower die base, a left template, and a right template. There are n sets of forging dies in total, with each set sharing an upper die. There is one upper template, one lower die base, n left templates, and n right templates. Each left template is installed to the left of each lower die, and each right template is installed to the right of each lower die. The upper die is installed on the upper template and located above the forging position. Each lower die is installed on the lower die base and transferred from the lower die base to the forging position. Each left die is installed... Each left mold is mounted on a left mold plate, and each left mold plate shares a left cylinder, and each right mold plate shares a right cylinder. The left cylinder is mounted on the left side of the forging position, and the right cylinder is mounted on the right side of the forging position. When the lower mold (i.e., the lower mold X) is transferred to the forging position, the left mold plate (i.e., the left mold plate X) mounted on the left side of the lower mold X moves to the left side of the forging position and connects with the left cylinder. The right mold plate (i.e., the right mold plate X) mounted on the right side of the lower mold X moves to the right side of the forging position and connects with the right cylinder. The upper mold is driven by the upper cylinder. The upper cylinder, in conjunction with the left cylinder and the right cylinder, drives the upper mold, the left mold plate X mounted on the left mold plate X, and the right mold plate X mounted on the right mold plate X to close with the lower mold X.

[0005] Further refining the above technical solution, the lower mold base is a slide table.

[0006] Further refining the above technical solution, each left template is supported by several left guide rails and slidably connected to several left guide rails, wherein the left guide rails are cantilever arms installed on the left end face of each lower mold; each right template is supported by several right guide rails and slidably connected to several right guide rails, wherein the right guide rails are cantilever arms installed on the right end face of each lower mold.

[0007] Further refining the above technical solution, each left template is connected to the left cylinder via a T-shaped head / T-shaped groove structure; each right template is connected to the right cylinder via a T-shaped head / T-shaped groove structure; at least one end of the T-shaped groove is open, and the opening is the inlet / outlet of the T-shaped head.

[0008] The above technical solution is further refined, with each left guide rail arranged side by side and lower down; each right guide rail is arranged side by side and lower down.

[0009] To further refine the above technical solution, the right end of the left guide rail is inserted into the left end face of each lower mold base, serving as a telescopic end; the left end of the right guide rail is inserted into the right end face of each lower mold base, also serving as a telescopic end; interference is avoided by telescopically avoiding interference through the right end of the left guide rail and the left end of the right guide rail.

[0010] Further refining the above technical solution, both the left and right guide rails are square rails.

[0011] A multi-directional forging method using the aforementioned multi-directional forging equipment; each forging die includes at least a pre-forging die and a final forging die, the billet is placed in the pre-forging die and forged to form a blank, the blank is placed in the final forging die and forged to form a product.

[0012] The advantages of this invention are that it is reasonably designed and ingeniously conceived. One multi-directional forging machine can complete several processes without the need for manual switching of forging dies, saving time and effort and increasing efficiency.
