[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 2 As shown, it includes a workbench 1, on which a hydraulic forging machine 2 is installed, in which a mold 3 for forging is movably installed, and parallel linear motors 4 and slide rails 5 are respectively provided on both sides of the workbench 1, and sliders on the linear motor 4 and the slide rails 5 are connected with connecting plates 6, on which a pushing head 7 is installed, and the pushing head 7 is arranged opposite to the hydraulic forging machine 2, and an injection structure connected to the pushing head 7 is provided on the workbench 1.

[0022] See also Figure 1-Figure 5 As shown, the jet structure includes an air pump 8 arranged on the workbench 1, a gas tank 11 is arranged on one side of the air pump 8, the air outlet of the air pump 8 is connected to the gas tank 11 through an air inlet pipe 9, and the gas tank 11 is connected to a solenoid valve 12; a main gas pipeline 7-1 is opened in the horizontal front-to-back direction in the pushing head 7, and a plurality of exhaust pipelines 7-3 are connected to the two sides of the main gas pipeline 7-1 through a plurality of connecting pipelines 7-2, the exhaust pipeline 7-3 is vertically opened in the pushing head 7, and the exhaust pipelines 7-3 are all through holes, the outlet of the solenoid valve 12 is connected to the main gas pipeline 7-1 through an air outlet pipe 14, a one-way valve 10 is arranged on the air inlet pipe 9, and the flow direction of the one-way valve 10 is toward the gas tank 11.

[0023] As an optimization scheme of the utility model, gas is output through the air pump 8, and the pressure of the gas is higher than the air pressure in the gas tank 11, so that the one-way valve 10 can be automatically opened, and the gas enters the gas tank 11 for storage. When the solenoid valve 12 is opened, the gas can flow out from the outlet pipe 14 and enter the main gas pipeline 7-1, and then be diverted through a number of connecting pipes 7-2 and ejected from the upper and lower ends of the exhaust pipe 7-3 respectively.

[0024] See also Figure 1-Figure 4 As shown, a plurality of flexible wear-resistant strips 15 are provided on the front side of the pushing head 7 .

[0025] As an optimization solution of the present invention, a flexible wear-resistant strip 15 is provided to reduce the wear caused by repeated use. At the same time, the flexible contact can reduce the damage to the surface of the accessory during the pushing process.

[0026] See also Figure 1-Figure 2 As shown, the gas tank 11 is provided with a barometer 13 .

[0027] As an optimization solution of the present utility model, the provision of a barometer 13 can facilitate the staff to monitor the air pressure status in real time and prevent the air pressure from being unbalanced.

[0028] The principle and use process of this utility model:

[0029] When in use, first install the mold 3 into the hydraulic forging machine 2, start the air pump 8, fill the gas tank 11 with enough gas, and then put the raw material to be forged on the mold 3 to start the hydraulic forging machine 2 to start working, press the accessories into shape, and then start the linear motor 4 to drive the connecting plate 6 and the push head 7 to move forward along the slide rail 5, and use the push head 7 to push out the formed accessories. At the same time, when the push head 7 reaches between the upper and lower molds 3, the solenoid valve 12 is opened, and high-pressure gas is ejected from the exhaust pipe 7-3 to clean the inside of the mold 3. At the same time, since the push head 7 is blocked between the upper and lower molds 3, the airflow will automatically flow to both sides after passing through the inside of the mold 3, and at the same time, it will bring out impurities without staying in the air. After closing the solenoid valve 12, the linear motor 4 is controlled to retract the push head 7, and a single processing operation is completed.
