Abstract
The present invention relates to steel plate material just can realize multistation processing progressive die through one stroke.Comprise mold, bed die, pressurizer is established in one end that bed die stamping press is less, and in the downward pressurized process of pressurizer, it successively decreases gradually to the resistance of mold.The invention provides a kind of in liquid crystal inner member production process, progressive die various piece can be made to keep pressure balance, thus ensure inner member machining accuracy and improve the progressive die for liquid crystal inner components in progressive die service life.
Description
Technical field
What the present invention relates to is a kind of device of Metal Forming technical field, and specifically a kind of steel plate material just can realize the progressive die of multistation processing through one stroke.
Background technology
Along with the development of national economy, the progress of product technology, LCD TV more and more spreads to huge numbers of families, and the thing followed is the market competition of excitation; For noticing that the requirement of parts backboard it is also proposed higher requirement, not only to alleviate design weight and the thickness of liquid crystal inner member further, improve the economy of liquid crystal backboard, and to ensure that inner member has enough intensity and precision, this just requires that inner member will ensure the depth of parallelism of each station in process of production and can not produce twisted phenomena, but inner member in process of production, relate to multiple different station, the feature related to comprises cuts shape, stretching etc., how to ensure that each station can meet processing request, there is very high difficulty.
In the production process of inner member, owing to relating to the operation of multistation, but the distributing position of each station on inner member is uneven, and this just causes in inner member manufacture process, inner member each portion pressure is inconsistent, and the pressure that is subject to of each portion of progressive die is also inconsistent thus; This just causes progressive die to there is pressure differential between each portion, thus easily produce vibration, make each die head not in same level, the inner member precision produced is caused not reach designing requirement, and the dystopy of this die head can make die head receive an oblique extruding force, cause the damage of die head, further can reduce the machining accuracy of inner member like this.
From the above, there is following defect in progressive die mould structure now: 1) machining accuracy of inner member is difficult to be guaranteed, and the percent defective of inner member is higher; 2) affect the mold use life-span, improve the processing cost of inner member, unfavorable economic benefit.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of in liquid crystal inner member production process, and progressive die various piece can be made to keep pressure balance, thus ensures inner member machining accuracy and improve the progressive die for liquid crystal inner components in progressive die service life.
Technical scheme of the present invention is: the present invention includes mold, bed die, and pressurizer is established in one end that bed die stamping press is less, and in the downward pressurized process of pressurizer, it successively decreases gradually to the resistance of mold.
Described pressurizer is 4, divides the surrounding edge being located at the less one end of bed die stamping press.
Described pressurizer adjustment pressure limit is 0-20KN.
Described pressurizer comprises one and is arranged on piston cylinder on bed die, and piston cylinder extends upward a piston rod, piston cylinder side on establish the valve that cylinder gas under piston cylinder can be made to flow out.
Described piston cylinder is provided with gas flowmeter, in order to detect the speed that lower cylinder gas flows out and the speed adjusting lower cylinder gas outflow.
Advantage of the present invention is: 1) the present invention arranges pressurizer on bed die, and this pressurizer can the pressure of compensated stage progressive die pressure smaller part, and progressive die each portion pressure is consistent; 2) because of progressive die in the course of the work, the pressure differential existed between each portion of progressive die can change thereupon, and the equalizing pressure of pressurizer of the present invention can change thereupon, can be the pressure balance that progressive die keeps each portion at any one time to greatest extent; 3) due to the balance of pressurizer, the inner member machining accuracy produced by the present invention is made to obtain comparatively stable guarantee, finished product rate is high, and can work under normal state all the time due to progressive die, make significantly to scheme the service life of progressive die to improve, become to produce cost and declined greatly; 4) the present invention's only plus-pressure balancer on the basis of original progressive die, structure is simple, improvement cost is low, for existing progressive die can be very fast be transformed into structure of the present invention, there is fabulous practical function, avoid the waste of existing progressive die.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described in detail:
The present invention includes mold 1, bed die 3, pressurizer 4 is established in one end that bed die 3 stamping press is less; The present invention is in order to make counterbalance effect better, and comprehensive actively benefit, respectively establishes a pressurizer 4 at the surrounding edge of the less one end of bed die 3 stamping press, amount to four, because only arrange the pressure differential that is difficult to the stable effective adjustment each portion of progressive die; If but pressurizer 4 is arranged too much, cause the net synchronization capability between each pressurizer 4 to be difficult to be guaranteed for a moment, affect pressure balance effect; Two due to progressive die station too much, the impact too much easily caused each station of progressive die is set; Therefore consider, the present invention arranges four pressurizers 4.
Further, progressive die in the course of the work, because the stamping press of die head will diminish gradually, will cause the pressure differential between each portion to diminish, and when this illustrates that progressive die just works, the pressure differential in each portion is maximum, then reduces gradually; This just require pressurizer 4 just pressurized time it should provide maximum balancing force, then successively decrease gradually, pressurizer 4 of the present invention can adopt following structure for this reason: pressurizer 4 comprises one and is arranged on piston cylinder 5 on bed die 3, piston cylinder 5 extends upward a piston rod 6, piston cylinder 5 side on establish the valve 7 that piston cylinder 5 times cylinder gases can be made to flow out; Piston cylinder 5 is provided with gas flowmeter, in order to detect the speed that lower cylinder gas flows out and the speed adjusting lower cylinder gas outflow, structure accordingly, pressurizer 4 of the present invention can according to the progress of the progressive die course of work, adjustment pressure supplement, make the pressure balance that progressive die can keep overall in the course of the work all the time, to ensure that the inner member after punching press 2 flatness is guaranteed, precision is effectively ensured.
According to time experience, pressurizer adjustment pressure limit of the present invention is 0-20KN.
