Abstract
The utility model discloses a kind of small-sized means for correcting for valve foundry goods, belong to casting deformation shaping tool field, mainly solving in prior art adopts jack to correct, the valve cracking technical problem of the wayward initiation of calibrated force, its technical scheme is: structure comprises chopping block, frame beam, rotating disk is provided with between chopping block and frame beam, the frame beam dish that can rotate carries out the rotation of certain angle, described frame beam upper end is fixed with drive unit, drive unit is also connected with dynamometer, and dynamometer is for measuring the driving force of drive unit; The utility model is provided with drive unit, after drive unit starts, band dynamic pressure plate can correct workpiece automatically, its dynamics corrected is fed back by dynamometer, and when after the force value that dynamometer reaches specified, drive unit stops afterburning, jack is more manually used to correct, time saving and energy saving, decrease workman's correction intensity, correct dynamics can accurate assurance simultaneously, there will not be because manual synchronizing dynamics is too large, the workpiece cracking phenomena caused.
Description
Technical field
The utility model relates to casting deformation shaping tool, particularly a kind of small-sized means for correcting for valve foundry goods.
Background technology
The as-cast structure of steel-casting easily produces more serious brilliant skill segregation, tissue odds, as casting section often surface be thin equiax crystal, two layers is column crystal, centre is equiax crystal, and Widmannstatten structure and network cementite, need eliminate by heat treatment (solid-state recrystallization) or alleviate its adverse effect, steel-casting controls its microscopic structure by heat treatment, reach the performance of needs, in addition, due to the wall thickness variation of steel-casting and the impact of structure, the each position of same foundry goods has different structural states, and produce sizable residual stress need eliminate, therefore, general Valve Steel Castings all requires to supply with condition of heat treatment, but, heat treatment also easily causes valve, particularly some deformation at flange position, for this reason, need to correct these deformation before dispatching from the factory, correct under in prior art, the valve after distortion is fixed on built-in beam by general employing jack, correct afterburning slow with jack, labor strength is large, and the dynamics of correction is wayward, the excessive valve that often makes of calibrated force produces cracking, cause and scrap.
Utility model content
The utility model, for above-mentioned technical problem, proposes a kind of midget plant for valve foundry goods, and this device can be out of shape by Fast Correction, and be easy to control correction dynamics, timing, labor strength is little.
In order to realize final purpose of the present utility model, intend adopting following technology:
A kind of small-sized means for correcting for valve foundry goods, comprise chopping block (1), the frame beam (2) be linked together with chopping block (1), rotating disk (3) is provided with between described chopping block (1) and frame beam (2), described frame beam (2) dish (3) that can rotate carries out the rotation of certain angle, rotational angle is less than or equal to 10 °, described frame beam (2) upper end is fixed with drive unit (4), drive unit (4) can be hydraulic jack or drive one in cylinder or other power set, correspondingly, if drive unit (4) is hydraulic jack, then drive unit (4) is also connected with Hydraulic Station, if drive unit (4) is for driving cylinder, then directly can connect the pneumatic tube system in factory, in addition, drive unit (4) is connected with dynamometer, dynamometer is for measuring the driving force of drive unit, and drive unit (4) lower end is also connected with the pressing plate (40) of movable dismounting.
Further, for alleviating the weight of described chopping block (1) and being convenient to process the flatness of chopping block (1), chopping block (1) is provided with bar-shaped trough (10) side by side.
The beneficial effects of the utility model are:
1. the utility model is provided with drive unit on frame beam, after starting drive unit, drive unit band dynamic pressure plate can correct workpiece automatically, and its dynamics corrected is fed back by dynamometer, when after the force value that dynamometer reaches specified, drive unit stops afterburning, for use jack artificial in prior art corrects, time saving and energy saving, decrease workman's correction intensity, correct dynamics can accurate assurance simultaneously, there will not be because manual synchronizing dynamics is too large, the workpiece cracking phenomena caused;
2. the utility model is provided with rotating rotating disk between chopping block and frame beam, when there is certain angle in workpiece above and below to be corrected, can according to the actual angle adjustment rotating disk of workpiece above and below, this device not only can correct the parallel workpiece in above and below like this, also can correct the workpiece that above and below exists certain angle.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of small-sized means for correcting for valve foundry goods, comprise chopping block 1, the frame beam 2 be linked together with chopping block 1, rotating disk 3 is provided with between described chopping block 1 and frame beam 2, described frame beam 2 dish 3 that can rotate carries out the rotation of certain angle, rotational angle is less than or equal to 10 °, described frame beam 2 upper end is fixed with drive unit 4, drive unit 4 can be hydraulic jack or drive one in cylinder or other power set, drive unit 4 is also connected with dynamometer, dynamometer is for measuring the driving force of drive unit, drive unit 4 lower end is also connected with the pressing plate 40 of movable dismounting.
When the utility model uses, workpiece after thermal deformation and valve foundry goods are placed on chopping block 1, start drive unit 4, drive unit 4 is with dynamic pressure plate 40 to be against workpiece surface, along with the Constant load of drive unit 4, after the force value of testing force device reaches specified measured value, drive unit 4 stops reinforcing, and after keeping the regular hour, drive unit 4 is with dynamic pressure plate 40 to return, correction completes, and takes off the workpiece corrected.
The utility model can automatically correct workpiece after workpiece is put well, its dynamics corrected is fed back by dynamometer, when after the force value that dynamometer reaches specified, drive unit stops afterburning, for use jack artificial in prior art corrects, time saving and energy saving, decrease workman's correction intensity, correct dynamics can accurate assurance simultaneously, there will not be because manual synchronizing dynamics is too large, the workpiece cracking phenomena caused.
