An internal high pressure forming device with a clamping mechanism

Abstract

The invention discloses a high-internal-pressure forming device with clamping mechanisms. The high-internal-pressure forming device comprises an upper die assembly, a lower die assembly and a clampingassembly. The clamping assembly comprises a first assembly and a second assembly, the first assembly is mounted on the upper die assembly, the second assembly is mounted on the lower die assembly, and the first assembly can move in the up-down directions; the first assembly comprises at least one threaded hole, the second assembly comprises fastening assemblies and through holes, the fastening assemblies and the through holes are in one-to-one correspondence to the threaded holes, and the fastening assemblies penetrate the through holes and the threaded holes, so that the second assembly andthe first assembly can be fixed. The high-internal-pressure forming device has the advantages that the fastening assemblies are connected with the threaded holes by the through holes in a threaded manner, so that the upper die assembly can be fixed onto the lower die assembly, and the high-internal-pressure forming device is in simple and convenient fixing modes; large-tonnage hydraulic machines for providing die clamping force can be omitted with the assistance of the mechanical clamping assembly, the high-internal-pressure forming device is favorable for saving the cost, and the adaptabilityof equipment can be improved.

Description

technical field [0001] The invention relates to an internal high-pressure forming device, and more particularly, to an internal high-pressure forming device with a clamping mechanism. Background technique [0002] Pressure forming, such as internal high-pressure forming nickel-based bimetallic composite pipe fittings, has unique advantages of high efficiency and low cost compared with surfacing technology, and is easy to mass-produce at low cost. Therefore, internal high-pressure forming technology is the development trend of single straight seam large-diameter nickel-based bimetallic composite pipe fittings. At present, internal high-pressure forming is mainly realized on ordinary hydraulic presses, so the control of internal high pressure and axial feed force of pipe fittings is not strict enough, and the forming rate is relatively low. Compared with forming processes such as forging and stamping welding, internal high pressure forming is still a relatively late technolog...

Problems solved by technology

In order to produce high-strength, integrated and large-sized parts, large-tonnage hydraulic presses are required to provide sufficient clamping force. However, this type of forming equipment has high costs and poor adaptability
