Hydraulic die forging machine

technical field

The invention relates to a die forging machine, in particular to a hydraulic die forging machine.

Background technique

At present, aluminum alloy wheels are mainly used in domestic and foreign sedans and other light vehicles. They have the characteristics of light weight, fast heat conduction, beautiful and luxurious, energy saving and safety. With the development of my country's automobile industry and the increase in demand for foreign auto parts, the market capacity very huge. At present, the methods of manufacturing aluminum alloy products at home and abroad include forging method and casting method. Although the forging method is of good quality, the yield is low, the production cost is high, and the price is expensive. Therefore, the casting method is generally used for production, but the ordinary gravity casting method is used for production. The production quality of the products is not high, and this production method is basically eliminated. At present, most of the international and foreign countries use the low-pressure casting method for production. The product quality and yield of this method have been improved to a certain extent, but the process is complicated and the equipment investment is huge. The forging method makes the aluminum alloy crystallize under high pressure, and produces a certain amount of deformation during the crystallization process, eliminating defects such as keyholes, porosity, and pores. Precision, and the investment is much lower than the low pressure casting method. Now there is an urgent need for an automatic hydraulic die forging machine that can stably fill at low speed and fast and solidify at high pressure.

Chinese utility model patent (CN 204799858 U) discloses a horizontal hot die forging machine, including a horizontal forging press and a forging die installed on the inner wall of the fuselage of the horizontal forging machine. There is a horizontal through hole, and a hot blank conveying pipe is installed and fixed in the horizontal through hole. The inner diameter of the blank conveying pipe is the same as the diameter of the cavity hole of the forging die. There is a reciprocating telescopic device. The diameter of the piston rod of the reciprocating telescopic device matches the inner diameter of the blank conveying pipe. The piston rod and the forging hammer move toward each other. After the piston rod extends, its end enters the forging die. In the inner short section, under the forging pressure of the forging hammer, the piston rod is slightly retracted, the thrust of the reciprocating telescopic device matches the forging deformation force of the blank, and the forging hammer retracts after the blank is forged into a forging, and the piston rod extends forward to push the forging. Push out, the telescopic frequency of the piston rod matches the working frequency of the horizontal forging press. It can be seen that the cold forged horseshoe bolt is prone to cracks in the head and the screw connection, and the yield is low; although the vertical hot die forging machine produces horseshoe bolts with high yield, not only the productivity is low, but also requires two people to operate, and labor costs are high. ; In order to overcome the shortcomings of the above-mentioned two existing technical equipment, this technical scheme designs a horizontal hot die forging machine that can be operated by only one person to solve the above-mentioned technical problems.

The upsetting mechanism is composed of a worm gear and a crank-slider mechanism, and the movement is reliable. The connecting rod in the crank-slider mechanism adopts a triangular truss structure, which greatly improves the force stability of the components. , reducing the vibration impact during the working process, the crank can rotate around the connecting slider to ensure that the movement direction is always consistent with the movement direction of the punch; the clamping mechanism is composed of a movable die and a fixed die, and the movement of the movable die moves through the cam It is composed of a mechanism and an auxiliary mechanism, with reliable movement, firm clamping and sustainable clamping. The auxiliary mechanism is composed of a worm gear and a crank slider mechanism, which is simple to assemble, practical and effective. It can be seen that the technical problem to be solved by this technical solution is to propose a small horizontal die forging machine, which ensures that the clamping device continuously clamps the workpiece during the processing and ensures the periodic movement of the punch.
