Description
Technical field
The utility model belongs to forging and stamping processing equipment technical field, and in particular to a kind of conventional press pressurize finishing die
Frame.
Background technology
Because the steel plate hardness of cold punching pressing formation is relatively low, it can not increasingly meet the use demand of people, in order to increase it
Intensity, can only be by way of increasing thickness, but this considerably increases overall weight again, is unsatisfactory for many engineerings and weight is wanted
Ask.
At present, the application of hot press-formed technology is more and more, to be heat-treated immediately after hot press-formed, improves steel
Plate hardness, steel plate can be made thin but stiff, meet the needs of in light weight, hardness is high；But the process of heat treatment easily makes stamping
Steel plate deformed, and do not reach requirement, it requires that heat treatment will keep mould to the pressure of steel plate on forcing press
In the case of carry out.A large amount of traditional cold punching pressing formation machines are all slider-crank mechanisms, there is provided continuous straight reciprocating motion, and mould
Tool upper mould be arranged on forging hammer sliding block on, do continuous straight reciprocating motion with mechanism, realize matched moulds punching press and the demoulding it is lower on
Action, but pressurize can not be realized, drop stamping and heat treatment can not be carried out；If do not fixed by the upper mould of mould with forging hammer sliding block
Connect to realize pressurize, deposit the problem of going up moulding/demoulding difficulty after heat treatment again.External drop stamping pressurize is set by numerical control
It is standby come what is realized, be not simple slider-crank mechanism, cost is higher.And the substantial amounts of conventional press of this country be also impossible to it is short
All updated in time, so being badly in need of solving the problems, such as to realize by conventional press hot press-formed.
In addition, mould is divided into core rod and mould bases, mould product is accessory processing during fabrication at present, and a core rod matches somebody with somebody one
Individual mould bases, cause the processing charges accounting of mould bases very high, mould bases needs to consume substantial amounts of steel, cause die manufacturing cost compared with
Height, the cycle is longer, and mould volume is big, and floor space is big, is unfavorable for very much organization of production.How the processing charges of mould is reduced,
Save cycle and resource, and a urgent problem to be solved.
Utility model content

Power machine works, and sliding block 11 pumps.It is out of service that first time reciprocating stroke terminates rear conventional press, stamping complete
Into sliding block 11 is up to leave the upper surface of parallels 6, plays and inlay card resistance, mould are provided in the bullet decorative pearl on top of an official cap groove that the decorative pearl on top of an official cap 3 is headed on guide pillar 19
Tool 16 itself also has punching press snap-in force, the two power along with the deadweight of mould bases and upper mould be more than on guide pillar 19 return spring 18 to
On elastic force, mould bases remains closed posture, realizes the pressurize of mould 16, can implement heat treatment operation.
Referring to Fig. 3, the parallels 6 is moved to the upper surface for being stripped depression bar 10 by original position, with being stripped depression bar 10
Coordinate and transmit pressure.Conventional press works, and sliding block 11 pumps.In second of stroke, first descending, the pressure of sliding block 11
Demoulding depression bar 10 is passed to by parallels 6, lever 15 holds horizontality when initial, and demoulding depression bar 10 and demoulding push rod 8 lower end are equal
With 15 corresponding end in contact of lever, because demoulding depression bar 10 has certain stroke in heavy platform, in the trip, demoulding depression bar 10 can
One end of lever 15 is freely pushed without being contacted with installation set 9（Do not contacted with upper plate）, acted on by leverage, through thick stick
Bar 15 transmit the force to the demoulding push rod 8, jack top mold frame, rigidity die sinking, top mold frame with mould 16 upper mould to move up realize
Die sinking, at the same guide column sleeve 4 it is up overcome play the active force of decorative pearl on top of an official cap spring 1 and moved back the decorative pearl on top of an official cap 3 is played out of bullet decorative pearl on top of an official cap groove on guide pillar 19
The bullet decorative pearl on top of an official cap 3 of sening as an envoy to acts on the other positions surface of guide pillar 19, plays the decorative pearl on top of an official cap 3 and no longer coordinates offer inlay card resistance with playing decorative pearl on top of an official cap groove.
When sliding block 11 reaches range, the process terminates, and the convex edge for being now stripped the upper end of depression bar 10 at most goes downwards to the step of heavy platform
Face or also no heavy platform step surface of arrival.
Referring to Fig. 4, the return spring 18 on second of reciprocating ascent stage, the guide pillar 19 of sliding block 11 stretches back
Bullet, further promote top mold frame up, final knockout course is completed, to dismount punching parts 17.
During implementation, further, the guide pillar 19, guide column sleeve 4 can have some sets to be applied in combination, and be uniformly arranged on mould 16
Surrounding, so, the guiding of the upper and lower mould bases relative motion and spacing guide rail are more, make upper and lower mould bases relative motion more
Add stablize it is smooth.During implementation, further, the demoulding push rod 8, depression bar 10, lever 15, the lever that mounting seat 13 forms are stripped
Mould emptier can have some sets, be uniformly arranged on the surrounding of mould 16, so, increase the stability of knockout course, make top mold frame
The top lift being subject to during the demoulding is more uniform, not unilateral.It is further, different according to the wall thickness of the guide column sleeve 4 during implementation,
The bullet decorative pearl on top of an official cap spring 1 can be all compressed in the bullet decorative pearl on top of an official cap hole on guide column sleeve 4, if the wall thickness of guide column sleeve 4 is relatively thin, ginseng
See Fig. 2, recessed bullet decorative pearl on top of an official cap spring accommodating chamber can be set on the length direction of spring base 2, compressed bullet decorative pearl on top of an official cap spring 1
Between the spring accommodating chamber bottom and the bullet decorative pearl on top of an official cap 3, so, it is adapted to the different situations for being configured at the wall thickness of guide column sleeve 4, also may be used
In the case of proof strength, in order to mitigate the weight of guide column sleeve 4, and the position-limit mechanism of Fig. 2 signals is used.The above-mentioned implementation
When can be regarded as falling into scope of protection of the utility model with further improved scheme.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
