Abstract
The utility model discloses a hydraulic high-pressure asbestos pad press molding machine, which consists of an upper press molding mechanism and a lower die cutting mechanism. The press molding mechanism comprises a locating sleeve and a hydraulic jack which is above the locating sleeve and moves axially along the central axle of the locating sleeve; the die cutting mechanism comprises a base, an external die which is fixed on the base, and a core die which is fixed on the base and at the centre of the external die. The lower part of the core die is sleeved with a resetting spring, and the upper part of the core die is sleeved with a lower moving die; the lower moving die is supported on the resetting spring; and the lower end of the hydraulic jack is connected with an upper hollow moving die which is capable of being sleeved outside the core die. Therefore, the quality of a high-pressure asbestos pad is improved; the high-pressure asbestos pad processed is in accordance with the size of the interfaces of a sluice valve and a grouting tube flange plate; the sealing effect is good, the appearance is standard, and the edge is neat, attractive and durable, and the skew during the butt joint of flange tubes is effectively prevented; in addition, time and labor are saved in manufacturing, and the working efficiency is more than 60 times than the working efficiency by handwork, so as to save a great amount of labor and time.
Description
Technical field: the utility model relates to a kind of process equipment, relates in particular to a kind of fluid pressure type high pressure asbestos pad molding press that is used to process the sealing gasket that uses between the pressure piping flange.
Background technology:
Visit in the normal work on anti-Young Pioneer's Day at mine, contact a large amount of pressure pipings, the gate valve parts, need to use a large amount of high pressure asbestos pads, and a big headache thing of preventing team's pincers worker is visited in having manufactured of these high pressure asbestos pads, past is always by manually copying asbestos pad the size of original asbestos pad to shear off with scissors, and then the inner core of asbestos pad is pounded with iron hammer, method is very original, it is suitable coarse to do manual work, the most important is exactly consuming time too big, waste not of uniform size the causing of asbestos pad that a large amount of time produces, the standard disunity, the pressure that is easy to generate two parts in the use is inhomogeneous.
Summary of the invention:
For solve between the pressure piping flange or the making of the asbestos seal pad that high pressure sluice valve uses exist take a lot of work, time-consuming, problem that product quality is not high, the purpose of this utility model provides a kind of production efficiency height, target level of product quality, standard, fluid pressure type high pressure asbestos pad molding press that result of use is good.
The technical solution of the utility model realizes in the following manner:
A kind of fluid pressure type high pressure asbestos pad molding press, it is made up of the press moulding mechanism of top, the molding machine structure of below, and wherein, press moulding mechanism comprises positioning sleeve, is positioned at the positioning sleeve top along the axially movable hydraulic jack in positioning sleeve center; The molding machine structure comprises base, be fixed on external mold on the base, be fixed on the base, the core at external mold center; The core bottom is with a back-moving spring, dynamic model is overlapped on top, and following dynamic model is supported on the back-moving spring; The jack lower end connects one can be enclosed within the outer hollow dynamic model of going up of core.
Last dynamic model is cylindric and interior external diameter with following dynamic model and equates.
The positioning sleeve internal diameter equates with the external mold internal diameter.
Core is cylindric or cylindric.
Good effect of the present utility model is:
1, improved the quality of making the high pressure asbestos pad; According to the interface size of gate valve and Grouting Pipe ring flange, sealing and pad are effective fully for high pressure asbestos pad after the processing, the profile standard, and neat in edge is attractive and durable, and what produce when effectively preventing the flanged pipe butt joint is crooked.
2, easy to operate, it is time saving and energy saving to make, and work efficiency has improved more than 60 times than manual, saves great amount of manpower and time.
Description of drawings:
Fig. 1 is a cross-sectional view of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As seen from Figure 1: the utility model is made up of the press moulding mechanism of top, the molding machine structure of below, wherein, press moulding mechanism comprises positioning sleeve 2, be positioned at the positioning sleeve top along the positioning sleeve center axially movable hydraulic jack 1; The molding machine structure comprises base 8, be fixed on external mold 4 on the base 8, be fixed on the base, the core 6 at external mold center; Core 6 bottoms are with a back-moving spring 7, dynamic model 5 under the cylindrical shape is overlapped on top, and following dynamic model is supported on the back-moving spring 7; Jack 1 lower end connect dynamic model 5 under the roof pressure, with following dynamic model 5 synchronizing sleeves dynamic model 5 on core 6 cylindricals are axially movable; Be it can also be seen that by Fig. 1: last dynamic model 3 is cylindric and interior external diameter with following dynamic model 5 and equates; Be it can also be seen that by Fig. 1: positioning sleeve 2 internal diameters equate with the external mold internal diameter; Be it can also be seen that by Fig. 1: core 6 is for cylindric or cylindric.
This fluid pressure type high pressure asbestos pad molding press operation principle: utilize hydraulic power unit as power source; after jack drives upward dynamic model rise; the asbestos raw material are delivered between dynamic model and the following dynamic model; reversing valve operated then; dynamic model is come downwards on the asbestos raw material face; because following dynamic model has the support of spring, and asbestos material is clamped, and continues descending again; external mold cuts away the asbestos material outer rim; internal mold cuts away core, and is reversing valve operated then, and last dynamic model is mentioned; because the effect of back-moving spring; following dynamic model rises, and the finished parts that presses is released, and finishes an impulse stroke.
