Abstract

The invention discloses a mechanical pipe fitting bulging device which comprises a stand main body, a main pressure oil cylinder, an upper die block, a lower die block, closed hydraulic plungers, a hydraulic system, a clamping control switch and an electric control system. The closed hydraulic plungers are arranged on both sides of the upper die block and the lower die block. The mechanical pipe fitting bulging device is characterized by also comprising a crank arm link mechanism and a guide mechanism, the crank arm link mechanism is hinged with the main pressure oil cylinder, the stand main body and the upper die block respectively. One end of the guide mechanism is fixedly connected with the stand main body, and the other end is fixedly connected with the upper die block. The mechanical device can increase the forming force of equipment and has the same effect on high pressure bulging in pipe fittings as big tonnage hydraulic equipment, so that the purchase cost of the equipment is reduced; and the production efficiency is improved due to the mechanical device. Compared with similar equipment, the mechanical pipe fitting bulging device has the advantages of small size and low energy consumption; and the performance conforms to production requirements, and the cost is reduced to 10-20% that of the similar equipment.

Description

technical field [0001] The invention relates to a high-pressure bulging device for hollow pipe fittings, in particular to a mechanical bulging device for pipe fittings. Background technique [0002] In the 1990s, due to the cost of fuel and raw materials and the strict restrictions on exhaust emissions by environmental protection regulations, the lightweight of automobile structures has become increasingly important. In addition to the use of light-weight materials, another important way to reduce weight is to use hollow structures and variable-section strong components in the structure, that is, for components that mainly bear bending or torsional loads, the use of hollow structures can reduce weight. , save material, and can make full use of the strength and rigidity of the material. Under this background, the internal high pressure forming of pipe fittings is an advanced manufacturing technology for manufacturing hollow light-body components. This technology has been wi...
