Located in the same vertical direction, starting the hydraulic cylinder 6 can drive the pressing block 7 to move in the vertical direction, so as to forge the raw material placed on the surface of the support frame 3. The workbench 1 is installed with an air intake assembly 4 at a surface position close to the support frame 3. The air intake assembly 4 includes an air intake hood 401 placed on the surface of the workbench 1. The bottom end of the air intake hood 401 is plugged with a connecting pipe 402. The workbench 1 is provided with a hole groove 11 at a surface position close to the support frame 3 for the connecting pipe 402 to be plugged, which improves the stability of the installation of the air intake hood 401. The air inlet at the top of the limit seat 2 is connected through a pipe. The air intake cover 401 is made of stainless steel and is funnel-shaped, which expands the air intake area at the top of the limit seat 2, thereby improving the absorption efficiency of metal dust. A hole groove 12 is provided on the side wall of the workbench 1 for the air outlet of the side wall of the limit seat 2 to be plugged in. A purification component 10 is fixed on the side wall of the workbench 1. The purification component 10 includes a shell 1001 fixed on the side wall of the workbench 1. The interior of the shell 1001 is clamped with activated carbon filter cotton 1004. By starting the limit seat 2, the air containing metal dust can be discharged into the shell 100 1, the surface of the activated carbon filter cotton 1004 is loose and porous, which can filter the metal dust in the air and then discharge the clean air, thereby reducing the dust content in the air and reducing the damage to human health. The side wall of the shell 1001 away from the workbench 1 is threadedly connected with an end cover 1002, and the side wall of the end cover 1002 is fixedly provided with a filter screen 1003. The filter screen 1003 is in a grid shape to facilitate air circulation.

The top positions of the limiting blocks 901 are symmetrically threaded with two groups of limiting bolts 903. The limiting bolts 903 penetrate the limiting blocks 901 and are threadedly connected to the surface of the support frame 3, thereby improving the forging stability.

[0024] A card slot 403 is provided on the side wall of the air intake hood 401, and a filter screen 404 is connected inside the card slot 403.

The external size of the filter screen 404 is compatible with the internal size of the card slot 403, thereby improving the convenience of installing and cleaning the filter screen 404.

[0025] Working principle: When using this type of hydraulic forging device, the operator first connects an external power supply, then places the raw material to be forged on the surface of the support frame 3, clamps it to the bottom of the raw material through the pressure groove 8, and then sequentially sleeves the two clamping grooves 902 on the ends of the raw material, and connects the limit block 901 and the support frame 3 together by tightening the limit bolt 903 to limit the displacement of the raw material. The forging is achieved by starting the hydraulic cylinder 6 to drive the pressure block 7 to move downward. When metal dust is generated, the operator can discharge the air containing metal dust into the outer shell 1001 by starting the limit seat 2. The surface of the activated carbon filter cotton 1004 is loose and porous, which can filter the metal dust in the air, and then discharge the clean air, thereby reducing the dust content in the air and reducing the damage to human health.

[0026] Secondly, the filter 404 is made of metal and is in a grid shape to isolate large particles of impurities to avoid clogging the connecting pipe 402. The outer size of the filter 404 is compatible with the inner size of the slot 403, thereby improving the convenience of installing and cleaning the filter 404.
