Abstract
The utility model discloses a guide device of a large hydraulic seal ring. The guide device is characterized by comprising a sleeve body assembled in a hydraulic cylinder body, wherein a flange plate fixed to the hydraulic cylinder body is connected to one end part of the sleeve body; one end of the sleeve body, close to the flange plate is horn-shaped. Therefore, the guide device has the advantages of relatively simple structure, relatively low manufacturing cost and relatively high practicality. Compared with the prior art, an operator can use the guide device to easily mount a main plunger into the hydraulic cylinder without specialequipment with relatively high cost.
Description
Technical field
the utility model relates to a kind of guiding device of large hydraulic seal ring, belongs to machining manufacturing technology field.
Background technique
On conventional large hydraulic press main plunger, there are three ring seal rings (oil sealing), are introduced in oil hydraulic cylinder and are not easy very much.Although the material of seal ring is rubber, there is certain elasticity, the size of seal ring (oil sealing) is larger, and resiliently deformable is less comparatively speaking, only depends on manpower to be difficult to operation; Adopt heating slightly to make its soft method, effect is also undesirable; And the method that employing equipment pushes by force can cause seal ring working portion damaged, cause sealing effect to decline.
Summary of the invention
The technical problem that the utility model solves is: provide a kind of and can easily main plunger be fit into the guiding device in oil hydraulic cylinder, to overcome the deficiencies in the prior art.
The utility model is to form like this: it comprises the sleeve body 2 being assemblied in hydraulic cylinder 1, is connected with the flange plate 3 being fixed on hydraulic cylinder 1 end face in sleeve body 2 one ends, and described sleeve body 2 is horn mouth shape near one end of flange plate 3.
In the guiding device of above-mentioned large hydraulic seal ring, described flange plate 3 is connected with hydraulic cylinder 1 end face by 6～10 bolts 4 that are evenly arranged thereon.
Owing to having adopted technique scheme, the utility model adopts flange plate that location is installed; Sleeve body is made as to horn mouth shape near one end of flange plate, for pushing lentamente main plunger and guiding its motion.Compared with prior art, without the higher special device of user cost, operator can be fit into main plunger in oil hydraulic cylinder like a cork smoothly.As can be seen here, the utlity model has that structure is comparatively simple, fabricating cost is lower, the good advantage of practicability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure that the utility model is looked up;
Being labeled as of accompanying drawing: 1-hydraulic cylinder, 2-sleeve body, 3-flange plate, 4-bolt, 5-main plunger.
Embodiment:
Embodiment of the present utility model: as shown in Figure 1, first according to the internal diameter size of hydraulic cylinder 1, make a sleeve body 2, the flange plate 3(connecting in an end of sleeve body 2 or sleeve body 2 and flange plate 3 are made to all-in-one-piece structures), sleeve body 2 is made into horn mouth shape (be sleeve body 2 outwards become gradually large near one end internal diameter size of flange plate 3) near one end of flange plate 3, again sleeve body 2 is arranged in hydraulic cylinder 1, and flange plate 3 is fixedly connected with the end face of flange plate 3.
For better fixedly the utility model, be beneficial to main plunger 5 is installed, flange plate 3 can be connected with hydraulic cylinder 1 by 6～10 bolts 4 that are evenly arranged thereon.As shown in Figure 2, through test of many times, be preferably and use 8 bolts 4.
Mode of execution of the present utility model is not limited to above-described embodiment, and the various variations of making under the prerequisite that does not depart from invention aim all belong to the protection domain of model utility.
