Abstract
The utility model relates to a hydraulic machine capable of realizing tonnage conversion. One side of a sliding block is connected with a plurality of plunger type cylinders, the other end of the sliding block is connected with a plurality of return cylinders, a power oil pipe supplies oil to all the plunger type cylinders, the return cylinders are connected with a return oil pipe respectively, a first solenoid valve and a second solenoid valve which can control connection and disconnection of an oil path are connected in parallel on the power oil pipe, an outlet of the first solenoid valve is connected with oil supply pipes of the plunger type cylinders located on the two sides of the sliding block and an outlet of the second solenoid valve is connected with an oil supply pipe located in the middle of the sliding block. When the first solenoid valve is opened independently, the plunger type cylinders on the two sides of the sliding block work, and first tonnage is provided; when the second solenoid valve is opened independently, the plunger type cylinder in the middle of the sliding block works, and second tonnage is provided. When both the first solenoid valve and the second solenoid valve are opened, the plunger type cylinders on the two sides of the sliding block and the plunger type cylinder in the middle of the sliding block all work, and third tonnage is provided. The number of the power oil cylinders can be controlled through opening and closing of the solenoid valves, and therefore tonnage conversion is realized.
Description
Technical field
The utility model relates to a kind of hydraulic press, particularly a kind of hydraulic press that carries out tonnage conversion.
Background technology
Along with the development of hydraulic press, client is also more and more to the instructions for use of lathe.Some client wishes that same a machine tool can produce product with different moulds, and for different formed product requirements, lathe needs the nominal pressure that provides different in forming process, and the application of tonnage switch technology is arisen at the historic moment.
The tonnage conversion of conventional hydraulic machine is before lathe work, tonnage to be changed mostly, and load is constant when lathe work, be mainly used in some workpiece correction, press-fit and forge, and the compressing technique such as powder metallurgy.For different Workpiece shaping requirements, before lathe work, switch the main tonnage of lathe.And the conversion of carrying out tonnage in the lathe course of work need to be adjusted oil circuit.
Utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of hydraulic press that carries out tonnage conversion is provided, simple in structure, easy switching.
For solving above technical problem, a kind of hydraulic press that carries out tonnage conversion provided by the utility model, slide block one side is connected with many plunger cases, the opposite side of slide block is connected with many kicker cylinders, power oil pipe is to each described plunger case fuel feeding, each described kicker cylinder is connected with backhaul oil pipe respectively, on described power oil pipe, be connected in parallel to can oil circuit control break-make the first magnetic valve and the second magnetic valve, the outlet of described the first magnetic valve is connected with the fuel feed pump of the described plunger case that is positioned at slide block both sides, the outlet of described the second magnetic valve is connected with the fuel feed pump of the described plunger case that is positioned at slide block middle part.
With respect to prior art, the utility model has been obtained following beneficial effect: when the first magnetic valve is opened, and when the second closed electromagnetic valve, the plunger case work of slide block both sides, the plunger case at slide block middle part is not worked, and the first tonnage is provided; When the first closed electromagnetic valve, when the second magnetic valve is opened, the plunger case work at slide block middle part, the plunger case of slide block both sides is not worked, and the second tonnage is provided; When the first magnetic valve is opened, when the second magnetic valve is also opened, the plunger case at slide block both sides and middle part is all worked, and the third tonnage is provided.The quantity that can control logical power oil oil cylinder by the break-make of magnetic valve, realizes the conversion of tonnage.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, accompanying drawing only provides reference and explanation use, non-in order to limit the utility model.
Fig. 1 is the oil channel structures schematic diagram that the utility model can carry out the hydraulic press of tonnage conversion.
In figure: 1. slide block; Plunger case of 2a.; No. bis-plunger cases of 2b.; No. tri-plunger cases of 2c.; 3. power oil pipe; Kicker cylinder of 4a.; No. bis-kicker cylinders of 4b.; 5. backhaul oil pipe; 6a. the first magnetic valve; 6b. the second magnetic valve.
The specific embodiment
As shown in Figure 1, the utility model can carry out the hydraulic press of tonnage conversion, slide block 1 one sides are connected with many plunger cases, example is that plunger case 2a, No. three plunger case 2c are positioned at the slide block left and right sides as shown in FIG., tonnage is respectively 300T, No. two plunger case 2b is positioned at slide block 1 middle part, and tonnage is 400T.The opposite side of slide block is connected with many kicker cylinders, and example is that a kicker cylinder 4a and No. two kicker cylinder 4b symmetries are positioned at the slide block left and right sides as shown in FIG..
No. one kicker cylinder 4a is connected with backhaul oil pipe 5 respectively with No. two kicker cylinder 4b, on power oil pipe 3, be connected in parallel to can oil circuit control break-make the first magnetic valve 6a and the second magnetic valve 6b, the outlet of the first magnetic valve 6a is connected with the fuel feed pump of No. three plunger case 2c with a plunger case 2a who is positioned at slide block both sides, and the outlet of the second magnetic valve 6b is connected with the fuel feed pump of No. two plunger case 2b that are positioned at slide block middle part.
When the first magnetic valve 6a opens, when the second magnetic valve 6b closes, a plunger case 2a and No. three plunger case 2c work of slide block 1 both sides, No. two plunger case 2b at slide block middle part do not work, and the first tonnage 600T is provided.
When the first magnetic valve 6a closes, when the second magnetic valve 6b opens, No. two plunger case 2b work at slide block 1 middle part, a plunger case 2a and No. three plunger case 2c of slide block both sides do not work, and the second tonnage 400T is provided.
When the first magnetic valve 6a opens, when the second magnetic valve 6b also opens, No. two plunger case 2b at plunger case 2a of slide block 1 both sides and No. three plunger case 2c and middle part all work, and the third tonnage 1000T is provided.
Just because of these three main tonnages of lathe can switch, practicality is greatly improved, and user can, according to different forming parts requirements, adjust the main tonnage of lathe, has really realized a tractor serves several purposes.
The foregoing is only the better possible embodiments of the utility model, non-ly therefore limit to scope of patent protection of the present utility model.In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
