Description
Technical field
The invention belongs to forming high pressure in pipe technical field, particularly a kind of intellectuality adapts to the inside high-pressure forming method of different length pipe.
Background technology
Forming high pressure in pipe technology, that one utilizes high-pressure liquid medium pressurization bulging and axial feed feed supplement, make the advanced manufacturing process of one that pipe laminating mold cavity is shaped, be one of the key technology that a kind of manufacturing realizes pressure forming high efficiency, product lightweight, product precise treatment, be applied widely in the field such as automobile, Aeronautics and Astronautics.But because tubing error in length when blanking cannot be avoided, when pipe length changes to some extent, often cause technological parameter inaccurate, or sealing is cut somebody's hair do not enter seal area, affect sealing effectiveness, then affect the quality of formed product.Therefore the manufacturing process that can adapt to different length pipe when finding a kind of internal high pressure forming is extremely urgent.
The present invention, just in order to solve an above-mentioned difficult problem, provides a kind of manufacturing process of the intelligentized adaptation different length pipe for internal high pressure forming hydraulic press.
Summary of the invention
The object of the invention is to provide the inside high-pressure forming method that a kind of intellectuality adapts to different length pipe, avoid due to drafting error bring pipe length to change time, cause sealing effectiveness poor, the problem that technological parameter cannot accurately be implemented.
The present invention first, cut somebody's hair 5 on a left side, the right side cuts somebody's hair on 9 and left dislocation sensor 1 is housed, right displacement transducer 12, the oil-feed oil circuit of left side oil cylinder 3, right side cylinder 10 is equipped with left pressure sensor 2, right pressure sensor 11, be respectively used to detect left cut somebody's hair 5, the right side cut somebody's hair 9 position and left side oil cylinder 3, right side cylinder 10 pressure; Work as device start, after patrix 6, counterdie 8 matched moulds, a left side cuts somebody's hair 5, cut somebody's hair in the right side 9 advances simultaneously, when a left side cut somebody's hair (5), the right side cuts somebody's hair and 9 touches the mouth of pipe respectively, when the pressure of left side oil cylinder 3, right side cylinder 10 arrives setting (1T-10T) pressure, a left side is cut somebody's hair 5 by computer control system automatically, cutting somebody's hair 9 liang and cut somebody's hair now respective absolute displacement as zero displacement point in the right side, then carries out forming high pressure in pipe subsequently.
During machine startup, left, cut somebody's hair and advance simultaneously in the right side, cut somebody's hair for a left side and arrive first, when a left side cut somebody's hair arrive first nozzle position time left pressure raise, when being elevated to pressure sensor SP1 setting pressure, computerized control system automatically using absolute displacement place of this place's displacement transducer as left side zero point, nozzle position has been by right side oil cylinder subsequently, when pressure is elevated to pressure sensor SP2 setting pressure, computer system automatically using absolute displacement place of this Bit Shift sensor as right side zero point, as both sides cylinder pressure SP1, after SP2 reaches setting pressure respectively, computer system changes according to the load path set during internal high pressure forming, complete corresponding actions.
The present invention has the following advantages:
1. the present invention can adapt to the internal high pressure forming technique of different length pipe.
2. the present invention introduces the Stress control of left and right side cylinder on the basis of the pure Bit andits control of tradition, pure Bit andits control is changed into displacement and pressure jointly controls, guarantee load path be cut somebody's hair touch the left and right end of pipe after implement, enhance the accuracy of technique.
3. the present invention introduces the Stress control of left and right side cylinder on the basis of the pure Bit andits control of tradition, pure Bit andits control is changed into displacement and pressure jointly controls, and ensures stability and the reliability of sealing, thus decreases percent defective.
In a word, the Bit andits control that tradition is cut somebody's hair by the present invention, changes displacement into and pressure controls simultaneously, ensure the enforcement of load path be cut somebody's hair touch pipe end after implement, intelligently can adapt to different pipe length, improve shaping initial stage sealing effectiveness, ensure that load path accurately and reliably.
