Abstract
The utility model relates to a compound type hydraulic material returning device, which belongs to the forcing press technology field. A small oil cylinder is arranged in a large oil cylinder, and a piston cylinder is not only taken as the piston of the large oil cylinder, but also taken as the cylinder body of the small oil cylinder simultaneously, therefore a compound type hydraulic material returning device which is provided with two working cylinders and two kinds of material returning force, and functions in stages, the cylinder diameter of one working cylinder is larger, therefore larger acting force can be provided in the early stage of the material returning, the cylinder diameter of the other working cylinder is smaller, therefore the speed is quicker when the cylinder works, and simultaneously the acting force can meet the requirement, and when being used, the working cylinders are installed below the platen of the forcing press or installed inside the sliding block, and can be matched with the die to make vertical reciprocating motion, and thus the compound type hydraulic material returning device is the special parts for expanding the process range of the forcing press. The hydraulic material returning device has the advantages that the structure is compact and reasonable, the working efficiency and the material returning quality of the forcing press can be improved, and the cotton dust recovery machine has strong practicability and remarkable economic efficiency.
Description
Technical field
The utility model relates to a kind of composite hydraulic discharging device, it is forcing press carries out head part when the compacting workpiece hydraulic pressure discharging device, be installed in forcing press platen below or slide block inside, can cooperate with mould and pump, be the special-purpose member that enlarges the forcing press processing range, belong to the press technologies field.
Background technology
Existing forcing press discharging device is simple in structure, and the working method of passive type, material returned power in the course of the work can not be along with workpiece suffered change in resistance and changing in die cavity, when causing the material returned consuming time many, efficient is low.
Summary of the invention
The purpose of this utility model is because of the existing passive working method of structural factor, the material returned many, situation such as efficient is low consuming time at existing forcing press discharging device, speed was very fast when work was provided, a kind of composite hydraulic discharging device that the while active force can be satisfied the demand.
The purpose of this utility model is achieved through the following technical solutions, and a kind of composite hydraulic discharging device is characterized in that described device is made of cylinder cap, cylinder body, piston cylinder, piston and clamp nut part; The clamp nut that the piston of piston cylinder, piston cylinder inner chamber and piston upper end spin is combined into small oil tank; The piston cylinder of cylinder body, inner chamber of cylinder block and the cylinder cap that is connected with cylinder body by screw are combined into large tank, and the oil-in that leads to the piston cylinder bottom is set on the cylinder cap, and the oil-in that leads to piston cylinder is set on the cylinder body, and the oil-in of piston is led in the piston cylinder setting.
Two seals separately is set between the inwall of nearly bottom of piston and piston cylinder, between the inwall of nearly upper end of piston and piston cylinder sealing is set.
Between the inwall of nearly bottom of piston cylinder and cylinder body, seal through sealing ring respectively between the inwall of cylinder cap and cylinder body.
The utility model is by being provided with small oil tank in large tank, and piston cylinder both as the piston of large tank, simultaneously also as the cylinder body of small oil tank, a kind of two working cylinders that have have been constituted, two kinds of material returned power, Zuo Yong composite hydraulic discharging device stage by stage, a working cylinder cylinder diameter is big, can provide bigger active force in the material returned incipient stage, another working cylinder cylinder diameter is less, and speed is very fast during work, active force can be satisfied the demand simultaneously, during use, be installed in forcing press platen below or slide block inside, can cooperate with mould to pump, it is the special-purpose member that enlarges the forcing press processing range, the utility model compact conformation is reasonable, can improve the operating efficiency and the material returned quality of forcing press, has very strong practicality and remarkable economic efficiency.
Description of drawings
Fig. 1 is the utility model sectional structure schematic diagram;
Among the figure, 1 cylinder cap, 2 cylinder bodies, 3 piston cylinders, 4 pistons, 5 clamp nuts, 6 oil-ins, 7 oil-ins, 8 oil-ins.
The specific embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, as shown in Figure 1, the utility model is by cylinder cap 1, cylinder body 2, and piston cylinder 3, piston 4 constitutes; The clamp nut 5 that the piston 4 of piston cylinder 3, piston cylinder 3 inner chambers and piston 4 upper ends spin is combined into small oil tank; The piston cylinder 3 of cylinder body 2, cylinder body 2 inner chambers and the cylinder cap 1 that is connected with cylinder body 2 by screw are combined into large tank, the oil-in 6 that leads to piston cylinder 3 bottoms is set on the cylinder cap 1, the oil-in 7 that leads to piston cylinder 3 is set on the cylinder body 2, and piston cylinder 3 is provided with the oil-in 8 that leads to piston 4; The import of the import of oil-in 6 hydraulic oil during as work, oil-in 7,8 hydraulic oil during as backhaul.Two seals separately is set between the inwall of piston 4 nearly bottoms and piston cylinder 3, between the inwall of piston 4 nearly upper ends and piston cylinder 3 sealing is set; Between the inwall of nearly bottom of piston cylinder 3 and cylinder body 2, seal through sealing ring respectively between the inwall of cylinder cap 1 and cylinder body 2.
Under general cold and hot die forging situation, workpiece is sticked together with die cavity under the high pressure effect of upper and lower mould, so the frictional resistance in a flash that workpiece is thrown off from die cavity is bigger, and back frictional resistance can descend greatly in case workpiece and die cavity get loose.For making workpiece break away from die cavity, after obtaining corresponding signal, by piston cylinder 3 liftout after clamp nut 5 and piston 4 rise in the lump.When to stroke 20mm and when ejecting force is greatly reduced, piston 4 quick liftouts are implemented next jig frequency thereby finish a jig frequency.Characteristics of the present utility model are to utilize the quick jacking mechanism of piston, reduce to about 1/10, improve the lathe operating efficiency simultaneously more than 10 times and the fluid power that moves back modular system is flowed.
