Abstract
The utility model discloses a die cushion structure with die cushion cylinders separated from a top cap. The die cushion structure with the die cushion cylinders separated from the top cap comprises the top cap (1), an upper cylinder (2), a lower cylinder (3), a piston rod (4) and a fixing seat (5), wherein an upper piston (6) is arranged inside the upper cylinder (2) in a sliding fit mode, a lower piston (7) is arranged inside the lower cylinder (3) in a sliding fit mode, the lower portion of the lower cylinder (3) is fixed on the fixing seat (5), the upper portion of the lower cylinder (3) is connected with the upper cylinder (2), the piston rod (4) is connected with the upper piston (6), the lower piston (7) and the top cap (1), and a gap exists between the upper cylinder (2) and the top cap (1). The die cushion structure with the die cushion cylinders separated from the top cap has the advantages of being low in manufacturing cost and low in maintenance cost.
Description
Technical field
The utility model relates to the punch press technical field, specifically is a kind of die-cushion cylinder and apical cap separate type die-cushion structure.
Background technology
Die-cushion cylinder in the prior art die-cushion structure and apical cap are an integral body, this die-cushion structure comprises apical cap, upper cylinder, lower cylinder, piston rod and holder, be sliding combined with upper piston in the described upper cylinder, be sliding combined with lower piston in the described lower cylinder; Described piston rod all is connected with upper piston, lower piston, apical cap; Described upper cylinder and apical cap are an integral body, and the bottom of described lower cylinder is fixed on the holder, and the top of described lower cylinder is connected with upper cylinder.There is following defective in the die-cushion structure of said structure in the use procedure of reality: because upper cylinder and apical cap are an integral body, so its machining accuracy is high, thereby causes its production cost high.Simultaneously, because both are an integral body, therefore when cylinder is changed, also need to change simultaneously apical cap, thereby cause its maintenance cost high.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, and a kind of production cost is low and maintenance cost is low die-cushion cylinder and apical cap separate type die-cushion structure are provided.
The technical solution of the utility model is, a kind of die-cushion cylinder and apical cap separate type die-cushion structure are provided, comprise apical cap, upper cylinder, lower cylinder, piston rod and holder, be sliding combined with upper piston in the described upper cylinder, be sliding combined with lower piston in the described lower cylinder; The bottom of described lower cylinder is fixed on the holder, and the top of described lower cylinder is connected with upper cylinder; Described piston rod all is connected with upper piston, lower piston, apical cap; Between described upper cylinder and the apical cap space is arranged.
Described piston rod is that bolt is connected with apical cap.
Described upper cylinder, lower cylinder are an integral body.
After adopting above structure, the utility model compared with prior art has the following advantages:
Between the upper cylinder of the utility model die-cushion cylinder and apical cap separate type die-cushion structure and the apical cap space is arranged, be upper cylinder with apical cap be from, therefore when the processing apical cap, need not too to pay attention to machining accuracy, thereby reduced to a certain extent production cost.Because both are not an integral body, therefore when cylinder is changed, need not to change simultaneously apical cap, thereby so that the maintenance cost of the utility model die-cushion structure is lower simultaneously.
Description of drawings
Fig. 1 be the utility model die-cushion cylinder and apical cap separate type die-cushion structure partly cut open figure.
Shown in the figure 1, apical cap, 2, upper cylinder, 3, lower cylinder, 4, piston rod, 5, holder, 6, upper piston, 7, lower piston.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of die-cushion cylinder of the utility model and apical cap separate type die-cushion structure, comprise apical cap 1, upper cylinder 2, lower cylinder 3, piston rod 4 and holder 5,2 are sliding combined with upper piston 6 in the described upper cylinder, are sliding combined with lower piston 7 in the described lower cylinder 3; The bottom of described lower cylinder 3 is fixed on the holder 5, and the top of described lower cylinder 3 is connected with upper cylinder 2; Described piston rod 4 all is connected with upper piston 6, lower piston 7, apical cap 1; Between described upper cylinder 2 and the apical cap 1 space is arranged, namely between upper cylinder 2 and the apical cap 1 be from, do not have annexation.
Described piston rod 4 is connected for bolt with apical cap 1.
Described upper cylinder 2, lower cylinder 3 are an integral body, and in the present embodiment, upper cylinder 2, lower cylinder 3 connect by a stay bolt, are conducive to like this improve the die-cushion reliability of structure.
Below only be described with regard to most preferred embodiment of the present utility model, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.In every case the various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
