Inner high pressure forming quick die assembling method and equipment

Abstract

The invention provides a die assembling and adjusting method and die assembling and adjusting equipment which is based on visual identity control, quick and accurate, convenient to assemble and disassemble and small in occupied space. The inner high pressure equipment is composed of a die assembling press machine, a horizontal cylinder, a high pressure source, a computer control system, a hydraulic pump station, a water pressure system and the like. The inner high pressure equipment further comprises flexible video cameras and an absorbable fixable mechanical micro-adjusting mechanism. Clearance computing is conduced based on vision, and therefore clearance computing is visual and convenient. A mobile computer is used for connecting the video cameras to observe needed spatial clearances in real time. During mechanical adjusting, an operator can move the mobile computer to the side of the person, and can operate the absorbable fixable mechanical micro-adjusting mechanism to conduct micro-adjusting through the method of observing the space inside video. The equipment only needs one mobile computer and a plurality of video cameras, no special equipment is needed and the equipment is simple and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of internal high-pressure forming of pipe materials, and in particular relates to a method and a device for rapid die-loading of internal high-pressure forming. Background technique [0002] Internal high pressure forming technology, the essential difference between it and water expansion is that it needs to be filled while expanding to compensate for the thinning of the wall thickness. Among them, the relationship between the feeding amount and the pressure versus time is called the loading path, and the reasonable design of the loading path is the key to determine the quality of the internal high pressure forming product. As a crucial external control parameter in the loading path, feeding is mainly driven by the feeding cylinder to drive the feeding rod to push the pipe along the axial space in the mold to realize the plastic flow of the material. Therefore, the feeding rod and the pipe in the mold The f...

AI Technical Summary

Problems solved by technology

The feeding cylinder generally weighs more than one or two hundred kilograms due to its large bearing capacity, and high-strength bolts are required to fasten; the internal high pressure forming mold generally weighs more than several hundred kilograms, and both the feeding cylinder and the mold need to be adjusted with auxiliary tools , but it is often difficult to fine-tune precisely, that is, the adjustment size is either large or small

Secondly, the movement and adjustment of the gap is mainly based on the observation of human eyes, but the mold installation space of the internal high-voltage equipment is compact and narrow, and it is difficult for people to enter for observation and debugging, resulting in large human errors and inconvenient operation

For internal high pressure forming with high matching requirements, it takes 2 to 3 hours to install and adjust a pair of molds, which is time-consuming and laborious, and the precision of mold installation is not high. When the error is large, it will directly affect the forming quality of the product, and the scrap rate is high.
