Abstract
The invention relates to a progressive die. By the progressive die, the multistation processing can be performed on a steel plate material by one stroke. The progressive die comprises an upper die and a lower die, wherein a pressure balancer is arranged at one end, with a smaller punching force, of the lower die; and the resistance of the pressure balancer to the upper die in the downwards pressurized process of the pressure balancer is gradually reduced. The invention provides a progressive die for a liquid crystal internal member. The progressive die for the liquid crystal internal member can maintain the pressure balance of various parts of the progressive die in the production process of the liquid crystal internal member so as to guarantee the processing precision of the internal member and prolong the service life of the progressive die.
Description
Technical field
What the present invention relates to is a kind of device of Metal Forming technical field, specifically is a kind of steel plate material just can realize multistation processing through one stroke progressive die.
Background technology
Along with development and 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; Also have higher requirement for the requirement of noting the parts backboard, not only to further alleviate the design weight and the thickness of liquid crystal inner member, improve the economy of liquid crystal backboard, and to guarantee that inner member has enough intensity and precision, this just requires inner member will guarantee 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 that relates to comprises cuts shape, stretching etc., how to guarantee that each station can both meet processing request, has very high difficulty.
In the production process of inner member, owing to relate to the operation of multistation, but uneven during the distributing position of each station on inner member, this just causes in the inner member manufacture process, each pressure of inner member is inconsistent, and the pressure that is subjected to of each of progressive die is also inconsistent thus; This just causes progressive die to have pressure differential between each one, thereby be easy to generate vibration, make each die head not on same horizontal plane, cause the inner member precision of producing 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, can further reduce the machining accuracy of inner member like this.
From the above, there is following defective 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) influence service life of mould, improve the processing cost of inner member, unfavorable economic benefit.
Summary of the invention
The present invention is directed to above-mentioned defective, it is a kind of in liquid crystal inner member production process that purpose is to provide, and can make the progressive die various piece balance that keep-ups pressure, thereby guarantee the inner member machining accuracy and improve the progressive die liquid crystal inner member progressive die in service life.
Technical scheme of the present invention is: the present invention includes mold, bed die, the less end of bed die stamping press is established pressurizer, and its resistance to mold successively decreases gradually in the downward pressurized process of pressurizer.
Described pressurizer is 4, divides the edge all around that is located at the less end of bed die stamping press.
It is 0-20KN that described pressurizer is adjusted pressure limit.
Described pressurizer comprises that one is arranged on the piston cylinder on the bed die, and piston cylinder extends upward a piston rod, piston cylinder the side on establish the valve that cylinder gas under the piston cylinder is flowed out.
Be provided with gas flowmeter on the described piston cylinder, in order to detect down the speed that cylinder gas flows out and to adjust the speed that cylinder gas down flows out.
Advantage of the present invention is: 1) the present invention is provided with pressurizer on bed die, and the pressure that this pressurizer can compensated stage progressive die pressure smaller part is consistent each pressure of progressive die; 2) because of progressive die in the course of the work, the pressure differential that exists between each one of progressive die can change thereupon, the equalizing pressure of pressurizer of the present invention can change thereupon, can be the pressure balance that progressive die keeps each one at any one time to greatest extent; 3) because the balance of pressurizer, make the inner member machining accuracy that produces by the present invention obtain comparatively stable assurance, finished product rate height, and because progressive die can be worked under normal state all the time, make significantly scheme to improve the service life of progressive die, become to produce cost and descended greatly; 4) the present invention's plus-pressure balancer on the basis of original progressive die only, simple in structure, improvement cost is low, for existing progressive die can both be very fast be transformed into structure of the present invention, have fabulous practical function, avoided the waste of existing progressive die.

The specific embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing:
The present invention includes mold 1, bed die 3, the less end of bed die 3 stamping presses is established pressurizer 4; The present invention is in order to make counterbalance effect better, comprehensive actively benefit, and edge is respectively established a pressurizer 4 around the less end of bed die 3 stamping presses, amounts to four, because a pressure differential that is difficult to each one of stabilizing effective adjustment progressive die only is set; If but pressurizer 4 is provided with too much, cause the net synchronization capability between each pressurizer 4 to be difficult to be guaranteed for a moment, influence the pressure balance effect; Two because the progressive die station is too much, and the influence that too much causes easily each station of progressive die is set; So take all factors into consideration, the present invention is provided with four pressurizers 4.
Further, progressive die because the stamping press of die head will diminish gradually, will cause the pressure differential between each one to diminish in the course of the work, and the pressure differential maximum of each one then reduced gradually when this explanation progressive die had just been worked; It should provide maximum balancing force when this just required the firm pressurized of pressurizer 4, successively decrease gradually then, pressurizer 4 of the present invention for this reason can adopt following structure: pressurizer 4 comprises that one is arranged on the piston cylinder 5 on the bed die 3, piston cylinder 5 extends upward a piston rod 6, piston cylinder 5 the side on establish the valve 7 that 5 times cylinder gases of piston cylinder are flowed out; Be provided with gas flowmeter on the piston cylinder 5, in order to detect down the speed that cylinder gas flows out and to adjust the speed that cylinder gas down flows out, structure in view of the above, pressurizer 4 of the present invention can be according to the progress of the progressive die course of work, adjust the pressure compensation value, make progressive die 4 can keep whole pressure balance in the course of the work all the time, be guaranteed to guarantee inner member 2 flatnesses after the punching press, precision is effectively guaranteed.
According to the time experience, it is 0-20KN that pressurizer of the present invention is adjusted pressure limit.
