A kind of oil cylinder connecting rod drive system for Composite Transmission hydraulic press
Technical field
The present invention relates to Composite Transmission hydraulic press, a kind of oil cylinder connecting rod for Composite Transmission hydraulic press drives System.
Background technology
In recent years, along with the fast development of Domestic Automotive Industry, the demand of automobile stamping covering rises year by year.At vapour In the production of car covering, forcing press occupies critical role.Today that and environment nervous in global energy increasingly deteriorates, fall Low energy consumption, Proper Match hydraulic energy-saving control system, to realize energy conservation most important to forging equipment.Due to punching machine Being limited by self structure, stroke is fixed, and pressure is wayward, the bad adaptability to technique.Although hydraulic press stroke, pressure can Control, Technological adaptability is good, but speed is slow, and production efficiency is low.A kind of Composite Transmission hydraulic press uses joining of symmetrical connecting rod and oil cylinder Close drive technology, reach punching production technology efficient, safe, high-quality, solve an above-mentioned difficult problem.This Composite Transmission hydraulic press Not only having the high speed of punching machine, high efficiency feature, it is excellent to be provided simultaneously with that hydraulic press shapes, Technological adaptability is good etc. Point.It is mainly used in the multistation block pressing forming process such as the drawing of automobile panel, punching, deburring, bending, shaping, possesses the highest Position and pressure controling precision, the multi-motion modes adapting to complicated moulding process demand can be developed.These hydraulic tools are standby The high of hydraulic press shapes quality, is provided simultaneously with the high efficiency of punching machine.The functional characteristic of its excellence is widely used in various Automobile panel sheet material stamping.Owing to introducing symmetrical link transmission technology, hydraulic press circulation time can be contracted significantly Short, and save installed power.
Summary of the invention
It is an object of the invention to for above-mentioned existing problems, it is provided that a kind of oil cylinder connecting rod for Composite Transmission hydraulic press Drive system, this system uses symmetrical connecting-rod force increasing device, defines bar-link drive system with oil cylinder, make hydraulic press have simultaneously Punching machine and the characteristic of hydraulic press, enhance the work efficiency of hydraulic press significantly.
Technical scheme:
A kind of oil cylinder connecting rod drive system for Composite Transmission hydraulic press, including symmetrical connecting-rod force increasing device and hydraulic pressure Oil cylinder, wherein symmetrical connecting-rod force increasing device is made up of symmetrical two groups of four linkages, each group of linkage by Toggle link, knuckle-pin, bar of exerting oneself, pin of exerting oneself, drive rod, drive pin, joint pin are constituted, and toggle link connects the upper horizontal stroke of hydraulic press by knuckle-pin Beam, drive rod connects the little slide of hydraulic press by drive pin, and bar of exerting oneself is connected with the slide block of hydraulic press by pin of exerting oneself, elbow Bar, drive rod and bar of exerting oneself connect further through joint pin, are driven the slide block of hydraulic press by the motion of the oil cylinder of hydraulic press, it is achieved The reciprocating motion of hydraulic press.
The technical Analysis of the present invention:
The power that in conventional hydraulic machine, oil cylinder applies acts directly on the slide block of hydraulic press, and the oil cylinder applying of hydraulic press The power that power is subject to equal to the slide block of hydraulic press.Being different from conventional hydraulic machine, this Composite Transmission hydraulic press has a kind of special height Efficiency symmetry connecting-rod force increasing device.The power that the oil cylinder of this hydraulic press applies is not to act directly on the slide block of hydraulic press, but By symmetrical connecting-rod force increasing device indirect action on the slide block of hydraulic press.Symmetrical connecting-rod force increasing device is close to lower dead point position Time there is the reinforcement coefficient of 6-8 times, relatively can reduce exerting oneself of master cylinder with tonnage with speed traditional oils press, make installation hold Amount reduces.
Advantages of the present invention and beneficial effect:
1) bar-link drive system of hydraulic press is to be driven little slide to move by oil cylinder, drives symmetrical connecting-rod force increasing device, tool There is the feature that compact conformation, efficiency are high;
2) symmetrical connecting-rod force increasing device has the reinforcement coefficient of 6-8 times when close to lower dead point position, relatively same with tonnage Speed traditional oils press can reduce exerting oneself of master cylinder, and installed capacity reduces;
3) have employed symmetrical linkage and connecting rod little slide guide pillar, balance radial component, can effectively overcome forcing press Eccentric load in work, thus keep the high accuracy of slide block.
Accompanying drawing explanation
Fig. 1 is the linkage arrangement schematic diagram of this system.
Fig. 2 is the main TV structure schematic diagram in hydraulic press local that this system relates to.
In figure: 1. bar of exerting oneself, 2. exert oneself pin, 3. drive rod, 4. drive pin, 5. knuckle-pin, 6. toggle link, 7. joint pin, 8. liquid The little slide of press, the 9. entablature of hydraulic press, the 10. slide block of hydraulic press, the oil cylinder of 11. hydraulic presses.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings, and embodiment described below will assist in and understands the present invention, but Protection scope of the present invention can not be limited with this.
