The invention discloses a small hydraulic press machine. The press machine comprises a base, side plates fixed on the base and an oil cylinder holder arranged on the side plates, wherein an inner side of each side plate is provided with a guide groove, and the oil cylinder holder is provided with a hydraulic cylinder and an upper mould return spring. An upper die base is connected with a piston of a hydraulic cylinder. Two sides of the upper die base are provided with guide wheels or sliding blocks which are positioned in guide grooves of the side plates and can move up and down. A lower die base is fixed on the base and side plates. A working platform is arranged on the side plates and comprises a platform top and an object positioning device. The press machine can mount different moulds on the upper and lower die bases to meet requirements of different operations. In addition, the press machine has the advantages of simple structure, small volume, light weight, low cost, large tonnage pressing operation, etc.
Description
technical field [0001] The invention relates to a press machine, in particular to a small hydraulic press. Background technique [0002] There are large and small presses in the prior art, and the large presses are complex in structure, large in volume and high in cost, and are difficult to be used by small-scale machining enterprises. Small presses have disadvantages such as unreasonable structure, uneven bearing capacity, low pressure, low work efficiency, and unsatisfactory use effects.
