Description
Technical field
A kind of local edge-neatening craftwork and punch-forming mold of punch-forming mold, belong to and strike out involved by this invention
V-neck V domain.
Background technique
By taking high-strength steel hot stamping die as an example, the prior art is mainly characterized by molding procedure and trimming process step being divided into twice
Process, and part needs are transported through.
If to increase edge-neatening craftwork content in molding procedure needs to consider the bigger challenge of two aspects: first is that for height
For strong steel plate cold forming and super-high strength steel thermoforming, press pressure often just can satisfy the molding demand of part itself,
And if increasing edge-neatening craftwork content on this basis, also need very big deburring pressure-plate-force and blanking pressure；Second is that due to
Punching process content is to complete moment, is often completed within preceding 2~5mm on earth in press molding, thus normally at
This increased part blanking pressure is moment increase and abrupt release on the basis of type power, it means that press and mold body all need
This partial pressure is undertaken, production may result in the damage of press damage and mold for a long time.
Therefore this field needs to develop a kind of technique that can stablize progress punch forming and carry out local deburring in the process.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of local edge-neatening craftworks of punch-forming mold, i.e., will be at
Pattern tool is combined together with Trimming Die technique, can molding procedure realize punching parts part sideline pre- deburring and in advance
Punching, stable structure are reliable.
The present invention provides a kind of local edge-neatening craftwork of punch-forming mold, the technique include press-molding process,
Mold bottom hydraulic buffer cylinder is for forming force and deburring process.
In the local edge-neatening craftwork of above-mentioned punch-forming mold, upper mould core that the hydraulic buffer cylinder is connected in press
For forming force when dropping to form 2-15mm.
In the local edge-neatening craftwork of above-mentioned punch-forming mold, the mold bottom hydraulic buffer cylinder is for forming force by electricity
Brain control.
The present invention provides a kind of punch-forming mold using above-mentioned local edge-neatening craftwork, the punch-forming mold packets
Press, upper mould core, lower die mold core, hydraulic buffer cylinder and lower die knife tool are included, the lower die mold core is divided into described hydraulic slow
Cylinder is rushed, the lower die mold core is adjacent with the lower die knife tool.The punch-forming mold integrally receives computer control, according to
Relevant action is completed in sequencing.
In above-mentioned punch-forming mold, the upper mould core is equipped with knife tool, with the lower die knife tool phase
Match.
Further, water route, the upper mold mould are equipped with inside the upper mould core of the punch-forming mold and lower die mold core
Core and lower die core surface are equipped with the water hole being connected with water route and rhone.
The heat pressing and molding mold has water spraying structure in mould, can quickly reduce the temperature of mold and part, adjusts water
Temperature reduces energy waste.
The working principle of the invention
It can be applied to the cold stamping of ultra-high strength steel plate, also can be applied to high strength steel plate drop stamping.Pass through this technology
Scheme can cancel subsequent trimming process step or at least reduce subsequent Trimming Die together, if subsequent edge-neatening craftwork uses
Laser cutting parameter if laser cutting time can be greatly decreased, and advantageously reduce laser cutting parameter to product ruler
Very little influence (heat that laser cutting parameter generates may result in part deformation).
Technical solution of the present invention and the maximum difference of existing schemes all on the market are the introduction of the use of hydraulic buffer cylinder.
By using hydraulic buffer cylinder solve molding procedure increase deburring action caused by press pressure acute variation and can
The problem of press caused by energy damages.For common molding die, the briquetting pressure of press is moving with press downlink
What work was gradually increased, the technology of the present invention perfectly solves above this problem: firstly, using hydraulic slow during forming parts
Cylinder is rushed as pressure source, since hydraulic buffer cylinder has the characteristics that pressure is big, is able to bear impact force, increase can be passed through
The quantity of hydraulic buffer cylinder, it is ensured that the pressure that hydraulic cushion steel provides can satisfy the demand of forming parts power；Part at
After the completion of type, since hydraulic buffer cylinder has the characteristic of buffering, with continuing traveling downwardly (even without press pressure for press
Power is greater than the starting force that cushion cylinder provides), complete edge-neatening craftwork content at this time.The pressure conduct that cushion cylinder provides at this time
Pressure-plate-force required for deburring, and the pressure of press downlink is as blanking pressure required for deburring.Since press downstream pressure is remote
Much larger than blanking pressure required for deburring, and most punching fluctuation can be offset by cushion cylinder, therefore press
Big ups and downs will not occur for pressure, so also damage would not be generated to the oil piping system of press, will not lead to mould inside
Balance cushion block be deformed or damaged by severe impact.After press molding on earth, hydraulic buffer cylinder loses pressure, so as to
It is relatively small for high-strength steel cold forming effect to act on all press pressures in moulding process content, but for super
Meaning is more great for high-strength steel thermoforming, because biggish pressure maintaining quenching pressure is necessary to super-high strength steel thermoforming.
In conclusion the introducing and Special use mode of hydraulic buffer cylinder, have been solved perfectly larger needed for edge-neatening craftwork
The problem of pressure-plate-force and blanking pressure, and pressure-plate-force and blanking pressure will not damage press and mold, in edge-neatening craftwork
Deburring part all loses pressure after the completion of appearance, will not influence the molding procedure of itself.
Technical solution of the present invention is quoted compared with scheme similar on the market by using hydraulic buffer cylinder, instead of normal
Advise the required nitrogen gas spring used, Normal hydraulic oil cylinder in edge-neatening craftwork.
The shortcomings that ordinary nitrogen spring, is all smaller for pressure-plate-force provided by single branch nitrogen gas spring, blanking pressure, needs more
Branch is used in series, occupied space it is larger and using when to will lead to mould structure more complicated, while will lead to required press ton
The phenomenon that position increases and recoils when will lead to press backhaul, and hydraulic buffer cylinder has deburring punching process in contrast
The characteristics of pressure can be greatly decreased after end of text neither will increase the demand of press pressure, also hardly cause press anti-
Punching.
Normal hydraulic oil cylinder is such as used as blanking pressure or pressure-plate-force source, it is smaller to equally exist single branch oil cylinder working-pressure, needs
It connects and more oil cylinders while using, on the other hand, the oil circuit of Normal hydraulic oil cylinder needs to connect press pipeline, although having
Make controllable advantage, but existing when punching process content efforts needs instantaneous pressure, pressure abrupt release problem also can be to oil
The circuit of cylinder oil circuit causes to challenge, meanwhile, the oil circuit pipeline that mold is connected with press or equipment will also result in potential oil leak wind
Danger.
Due to the introducing of hydraulic buffer cylinder and certain moduli lamps structure design method in technical solution of the present invention, so that mould
The pressure control for having different die cavitys becomes possibility.Hydraulic buffer cylinder itself can form an entirety by way of pipe going here and there,
And different initial pressures can be realized by adjusting the valve of hydraulic buffer cylinder, and then it is different that different die cavitys may be implemented
Forming force is adjustable, therefore is conducive to the subtle adjustment of the different cavity forming power, forming gap of a mould with multi-cavities.
In terms of cost: technical solution of the present invention is by introducing the use of hydraulic buffer cylinder and corresponding special
Mould structure design, part deburring sideline may be implemented and develop in advance, part is had to repair and rushes the production of garbage collection equipment
Also the pre- exploitation that part punching may be implemented for line effectively reduces the development difficulty or laser of subsequent trimming-punching die
The workload of cutting action greatly reduces the production cost of part.And for similar on the market molding die and deburring work
For the mode that skill combines, improve the stability and reliability of production, eliminate damage to press and it is excessively high at
Type pressure demand.
Technical solution of the present invention equally can partially be suitable for special flange, shaping, also cooperate inclined wedge while use.
