Description
Technical field
The utility model relates to plant equipment automatic control technology field, specifically a kind of improvement invention of guiding mechanism of closed dead point of fine-edge blanking hydraulic press.Dead-centre position precise adjusting device is closed in particular to a kind of fully automatic hydraulic essence impact machine.
Background technology
Fine-edge blanking hydraulic press (hereinafter referred to as smart impact machine) grows up on common stamping machine basis, fine-edge blanking is powerful flanging stamping-out, technological principle is on triple action press, utilize the fine blanking die of special construction, under forceful action, make material produce plasticity, detrusion, thus obtain the fine blanking part of high-quality.Essence impact machine must provide blanking pressure, pressure-pad-force and counter-pressure simultaneously; main frame should have high strength and high rigidity; slide block can ensure accurate guiding; and can the height at closed dead point and repetitive positioning accuracy on accurate adjustment mould; reliable mould defencive function to be possessed simultaneously, be a kind of high investment, the equipment that technology-intensive and added value of product is high.Because the blade clearance of smart impact machine mould is very little, in order to improve punching quality and die life, the upper closed dead point of slide block must be adjustable, and have the repetitive positioning accuracy of height.Smart impact machine in the past adopts merely the mode of hydraulic pressure or electic protection to adjust upper closed dead point, and the safety coefficient of mould and equipment is low.So upper closed dead point adjust of employing mechanical system to smart impact machine is the important content during smart impact machine manufactures and designs.Along with the difference of fine blanking part thickness and technical requirement, the shut height of mould is also different, the monolateral gap of mould punch-die is that 0.5% material is thick, due to the characteristic of fine blanking technology, have higher requirement to the die shut height Adjustment precision of lathe and repetitive positioning accuracy, resetting error will be less than and equal 0.03MM.Therefore, this just has higher requirement to the performance of smart impact machine and die cutting accuracy.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of rational in infrastructure, accurate a kind of full-automatic essence of closed height adjustment to rush hydraulic press closed height adjusting device.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to realize: this kind of full-automatic essence rushes hydraulic press closed height adjusting device, comprise body and be arranged on the work top on body, the bottom of described work top is provided with table surface height adjusting device, described table surface height adjusting device comprises cylinder body, be arranged on the main piston in cylinder body, also comprise described in it is characterized in that and eliminate screw thread pair inter space device, this device described comprises the adjustment screw rod be sleeved on main piston, described adjustment screw rod is screwed onto on the internal thread of cylinder body, described adjustment screw rod is bolted with hoisting nut, described adjustment screw rod is connected with gear wheel, described gear wheel and driving motor are in transmission connection, described hoisting nut is fixed on cylinder body shoulder by alignment pin, described cylinder body shoulder is also provided with annular piston, this annular piston withstands hoisting nut when operating mode, eliminate adjustment screw rod and the screw thread pair of cylinder body internal thread and the screw thread pair gap between hoisting nut and hoisting nut.
As preferably, described gear wheel is also provided with the follower of tracking adjustment screw rod straight-line displacement, described follower includes position sensor, and this position sensor and the position sensor be arranged on body match.
The beneficial effects of the utility model are main piston main motion parts as lathe, the screw thread pair that cylinder body and adjustment screw rod form is as the mechanical position limitation of lathe, thread pitch is eliminated by brute force, thus ensures the repetitive positioning accuracy of lathe, meets the requirement of fine blanking technology completely.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is the structural representation of the main haulage gear of the utility model.
Detailed description of the invention
Drawings illustrate structure of the present utility model, further illustrate its details by reference to the accompanying drawings more below.This kind of fully automatic hydraulic essence impact machine closed height adjusting device, comprise body and be arranged on the work top on body, the bottom of described work top is provided with table surface height adjusting device, described table surface height adjusting device comprises cylinder body 1, be arranged on the main piston 6 in cylinder body 1, also comprise and eliminate screw thread pair inter space device, this device described comprises the adjustment screw rod 7 be sleeved on main piston, described adjustment screw rod 7 is screwed onto on the internal thread of cylinder body 1, on described adjustment screw rod, 7 are bolted with hoisting nut 4, described adjustment screw rod 7 is connected with gear wheel 8, described gear wheel 8 is in transmission connection by gear reduction unit 9 and driving motor 10, described hoisting nut is fixed on cylinder body shoulder by alignment pin 5, described cylinder body shoulder is also provided with annular piston 2, this annular piston withstands hoisting nut when operating mode, eliminate adjustment screw rod and the internal thread of cylinder body and the screw thread pair gap of hoisting nut and hoisting nut.
This device can also be provided with the follower 3 of tracking adjustment screw rod straight-line displacement on described gear wheel, and described follower includes position sensor, and this position sensor and the position sensor be arranged on body match.
The utility model forms powerful elimination screw thread pair gap oil cylinder by the built-in annular cylinder of oil cylinder shoulder and annular piston, the output shaft of motor is connected with gear reduction unit, the output gear shaft of gear reduction unit and gear wheel engagement, motor controls the rotary motion of gear wheel through reductor, gear wheel is connected by screw and alignment pin with adjustment screw rod, convert the rotary motion of gear wheel to straight line rotary composite movement, the built-in sensors instant tracking adjustment screw rod straight-line displacement stroke of described follower, and form full closed loop control with servomotor, ensure die shut height Adjustment precision.
During the precise adjusting device work of closed dead-centre position, first eliminate in-oil cylinder pressure oil, make its cylinder interior pressure be zero, piston declines, now, hoisting nut, because deadweight can move down, now, has gap between each screw thread pair, at this moment adjust screw rod to be rotated freely by Electric Machine Control, because hoisting nut is fixed on cylinder body by alignment pin, this alignment pin ensures that in adjustment screw rod rotary movement, hoisting nut can not produce circumferential displacement.After closed dead-centre position has adjusted, screw thread pair gap is eliminated in oil cylinder and is fed pressure oil by machine tool hydraulic system, hoisting nut is up withstood by annular piston, because annular piston area is larger, the powerful gap of eliminating each screw thread pair of meeting, ensure lathe in the course of the work, adjustment screw rod can not produce small swing offset, this ensures that theres the uniformity of punching precision simultaneously.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
