The lower part of the working space of the machine body 1 is provided with a lower die, the movable end of the main cylinder 2 is connected with an upper die, and in the application of the scheme, the main cylinder 2 completes die pressing and also completes die cutting.

Through this device, can realize when the master cylinder adds man-hour to the mould, combine the mould to accomplish both sides simultaneously and punch a hole, and the work piece of opposite side is beaten the mark, and whole in-process work piece need not to shift the station, and direct once only accomplishes processing, very big improvement machining efficiency. The front end of a piston rod of each cylinder body is provided with a die meeting the forming requirement of the forged piece, and the piston rod and the die move forward under the action of high-pressure oil provided by a hydraulic station, so that metal deformation is realized, and the required forged piece is obtained.

The forging piece printed by the die is a die forging piece, after the general die forging piece is heated, firstly, blank making, secondly, forming and finally, redundant burrs are cut off, namely, edges are cut, the workpiece with the holes needs to be punched, and the special forging piece needs to be printed additionally.

By combining the arrangement of the scheme, the five processes of blank making, forming, trimming, punching and typing can be completed on one device (namely multi-station). Blank making, forming and trimming are completed by the main cylinder 2, punching is completed by the side cylinder 4, and typing can be performed by the rear cylinder 3.

Because the variety of forgings is various and the requirements are different, the traditional forming equipment only has up-and-down action and can only finish simple forgings. In addition, the complex forging not only needs the hitting force of the up-and-down motion, but also needs the hitting force in the horizontal direction. This scheme is furnished with the hydro-cylinder that the level was beaten at the shaping station, and side jar 4 and back jar 3 promptly also can satisfy the fashioned multidirectional forging and pressing requirement of complicated forging more the subassembly of cylinder body tip when needs use.

Greatly improving the working efficiency and greatly reducing the labor intensity of workers. All action requirements of the whole equipment can be met by one set of power system, and energy consumption is saved.

2. The hydraulic cylinders in multiple directions are integrated, and the floor area is small. Five devices are needed in the traditional five procedures, and the floor area is reduced by 2/3. Because of adopting hydraulic transmission, the vibration and noise generated by mechanical transmission are avoided.

3. The scheme has low requirement on the installation foundation of the equipment. The forming equipment with mechanical transmission has high basic requirement (generally accounting for about 10% of the total investment of the equipment) due to impact load, and the scheme only accounts for about 1% of the total investment of the equipment.

4. The scheme has the function of multidirectional forging equipment and can meet the forming requirement of complex forgings.

5. The working space of the scheme is in an open design, and is suitable for being equipped with a mechanical arm or a robot, so that the whole automation is realized. In particular, in the blank making process, the traditional process uses free forging equipment (namely an air hammer), and unmanned operation cannot be realized, so that the scheme has no problem.
