Here, if internal high pressure forming is performed on multiple complex pipe fittings at the same time, it may appear as follows image 3 In the situation shown, that is, the extension lines of the pipe ends of multiple pipe fittings 6' intersect and interfere with each other. If the scheme of moving the feeding hydraulic cylinder is adopted, it will be like image 3 That would cause interference in the installation positions of the two feeding hydraulic cylinders 1'
Moreover, the ports of some pipe fittings are facing upwards, downwards, left or right, and if the feeding hydraulic cylinder is fixed in this way, it may interfere with the clamping master cylinder for mold clamping

Embodiment Construction
[0062] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.
[0063] Such as Figure 4-Figure 6 Shown is Embodiment 1 of the internal high pressure forming equipment of the present invention. This embodiment is a kind of equipment for internal high-pressure forming of complex pipe fittings, including a frame 1, the frame 1 is a frame made of several stainless steel plates welded to each other, has high strength, is fixed firmly, and will not be subjected to internal high pressure Vibration occurs during forming.
[0064] In the frame, a mold clamping master cylinder 2, a booster pump 3 connected to a water tank 12, and an internal high-pressure mold 4 are fixed. Specifically, a cavity 1.1 is provided in the middle of the frame 1, and the lower bottom of the cavity It is provided with a horizontal worktable surface 1.1.1, slide rails 1.1.2 are installed on the left and right side walls of the cavity, a...

The invention discloses hydro forming equipment for a complex pipe fitting, and an application method of the equipment. The equipment can be used for machining a simple pipe fitting, can simultaneously machine multiple pipe fittings at one time as multiple die cavities are arranged, and is high in work efficiency. In addition, the hydro forming equipment can also be used for machining the complex pipe fitting; as a converting mechanism is arranged in a hydro forming die, the horizontal thrust of a horizontal push head of each supplementing hydraulic cylinder can be converted into axial thrust consistent to the axial line of the pipe fitting, and as the supplementing hydraulic cylinders are still arranged on two sides of the hydro forming die, moving is not needed; thus, the worktable area of the whole hydro forming equipment is reduced, and the procedure of moving the supplementing hydraulic cylinders is avoided, so that the machining accuracy is improved; the equipment and the application method are suitable for numerical control machining.
Description
technical field [0001] The invention relates to the technical field of internal high pressure forming, in particular to a device for internal high pressure forming of complicated pipes and a method for using the same. Background technique [0002] Hydroforming, also known as hydroforming or hydraulic forming, is a material forming process that uses liquid as a forming medium to achieve the purpose of forming hollow parts by controlling internal pressure and material flow. [0003] In the prior art, an internal high pressure forming machine is disclosed in the Chinese Invention Patent Publication No. 201010522779.5, which includes an upper seat, a slider and a hydraulic cylinder arranged on the upper seat. The extension rod of the hydraulic cylinder is connected to the The sliders are connected, and the hydraulic cylinder at least includes a piston cylinder and a plunger cylinder. The internal high pressure forming machine provided by the embodiment of the invention is desig...
