The positioning accurate control method of traditional hydraulic press mainly contains two kinds: (1), hydraulic control, often adopt electrohydraulic servo valve or proportioning valve highly sensitive, that response is fast, precision is high, its shortcoming is that the positioning precision of in fact equipment is subject to the impact of mechanical transmission mechanism very large, not that only servomotor performance just can meet control, the cost of hydraulic control is simultaneously high and control procedure is complicated, controls difficulty large.(2), machinery is controlled, as adopt the methods such as dead position block, although the method cost that adopts machinery to control is relatively low, its shortcoming is the destruction that pure mechanical collision can be accelerated positioner, have a strong impact on precision, persistence and the stability of location, and then affect the high accuracy of product.
On January 16th, 2013, Chinese utility model patent CN202668818U discloses a kind of mould matched moulds positioner, this positioner adopts, at the upper and lower mould of mould, a locating piece is all respectively set, and the groove of the projection of upper locating piece and the lower locating piece incompatible matched moulds of realizing that matches is located.This positioner adopts mechanical location, in long-term use procedure, along with its positioning precision of the aggravation of wearing and tearing between locating piece will significantly reduce, causes Product Precision to decline.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned defect, and the localization method of a kind of hydraulic test matched moulds that weares and teares little, positioning precision is high by positioner and convenient and flexible operation is provided.
In order to solve the problems of the technologies described above, the invention provides a kind of hydraulic test matched moulds positioner, it comprises the patrix and the upper collision block that are arranged on can up and down crossbeam, is arranged on counterdie and lower collision block on workbench; Described upper collision block is positioned at patrix side contour with patrix, and described lower collision block is positioned at counterdie side contour with counterdie, and described upper collision block is corresponding with lower collision block position, connects respectively the both positive and negative polarity of electric control gear, and insulate with moved cross beam, workbench.
Beneficial effect of the present invention be its both overcome hydraulic control system complicated, control that difficulty is large, the high deficiency of controlling cost, overcome again pure machinery and control that positioning precision is low, the shortcoming of poor stability, when upper and lower collision block contact, system is cut off pressurization oil circuit, now the upper and lower mutual impact force of collision block is very little, has reduced wearing and tearing between upper and lower collision block, has extended its service life, has improved positioning precision.
In order to promote positioning precision, described upper collision block is two, is separately positioned on the both sides of patrix; Described lower collision block is two, is separately positioned on the both sides of counterdie.
In order to adapt to the location requirement of differing heights and reliable and stable, the height-adjustable of described upper and lower collision block is also locked by locking nut.
The present invention also provides the localization method of a kind of hydraulic test matched moulds with positioner, comprises the following steps:
1), regulate the height of upper and lower collision block and upper and lower mould contour;
2) both positive and negative polarity that, upper collision block, lower collision block is connected respectively to electric control gear;
3), switch on power, start hydraulic test pressurization oil circuit, Hydraulic Cylinder crossbeam moves downward along guide rail;
4), crossbeam drives patrix and upper collision block to move downward simultaneously, after upper collision block contacts with lower collision block, pressurization oil circuit is connected and cut off to electric control gear, matched moulds process finishes.
This method operating process is simple and easy to do, with low cost, control accuracy is high, shows that after tested its positioning precision is in 10-20 μ m, compares servo-controlled 30 μ m, and the 60 μ m that machinery is controlled have greatly improved.
