Problems solved by technology

[0004] 1. Existing internal high pressure forming equipment for pipes is used to control the forced displacement of the left and right thrust cylinders to carry out axial feeding when making parts. This active and compulsory mechanical feeding method is difficult to match the deformation of the blank. In the process of mold forming, it is easy to cause insufficient or excessive feeding, and it is difficult to reasonably control the amount of feeding, and it is difficult to control;
[0005] 2. By artificially setting the feed amount, that is, controlling the displacement of the left and right thrust cylinders to feed the feed, it is easy to cause insufficient feed amount, which leads to the phenomenon of cracking due to insufficient feed and untimely filling during the expansion process, resulting in high pressure expansion. type failure;
[0006] 3. The sensitivity of feeding control is not high, and it is also easy to cause the rapid deformation of the tube blank due to the internal pressure of the tube blank reaching the material yield point during the forming process, causing the material at the two ends of the tube to quickly flow into the mold cavity, which is easy to produce tube The two ends of the mouth are separated from the left and right push heads, resulting in the leakage of the high-pressure liquid that has been established inside the tube blank, and the most fundamental internal high-pressure forming conditions cannot be guaranteed;
[0007] 4. Excessive feeding will easily lead to forming defects such as wrinkling, wrinkles, and thickening of the parts in the forming area, resulting in the failure of the parts to bulge

Abstract

The invention discloses a left-right symmetrical three-way pipe internal high-pressure forming equipment. The internal high-pressure forming equipment includes a clamping press, a booster system, an electrical control system, an upper mold, a lower mold, an oil pump, and is installed on a workbench. The left thrust head, right push head, left thrust cylinder, right thrust cylinder, and material support cylinder; this equipment ensures that the high pressure inside the pipe will not cause pressure relief failure during the forming process, avoiding the formation of wrinkles in the forming area of ​​the pipe, and at the same time It also avoids the phenomenon that the pipe material is not filled in time to cause bursting when rapid deformation occurs, and finally ensures that the pipe parts are stable and gradually formed and shaped.

Description

technical field [0001] The invention belongs to the technical field of internal high-pressure forming of pipes, in particular to a left-right symmetrical three-way internal high-pressure forming equipment for pipes. Background technique [0002] The principle of internal high-pressure forming of pipes is: after the upper and lower molds are closed, the pipe is sealed by the left and right push heads and the pressure forming medium is injected into the pipe, and the internal pressure of the pipe is realized under the joint action of the left and right push heads and the internal pressure. take shape. Compared with the traditional processing technology, the parts obtained by this forming method have a series of advantages such as low cost, light weight, material saving, less processing steps, high forming quality, good mechanical properties, and high rigidity and strength. [0003] The problems existing in the existing pipe internal high pressure forming equipment are: [00...
