Abstract
The invention discloses a hydraulic press molding machine of a high-pressure asbestos pad, consisting of an upper press molding mechanism and a lower mold cutting mechanism. The press molding mechanism comprises a locating sleeve and a hydraulic jack, wherein the hydraulic jack is arranged above the locating sleeve and axially moves along the center of the locating sleeve. The mold cutting mechanism comprises a base, an outer mold and a core mold, wherein the outer mold is fixed on the base, and the core mold is fixed on the base and at the center of the outer mold. A return spring is sleeved on the lower part of the core mold, a lower moving mold is sleeved on the upper part of the core mold, and a lower moving mold is supported on the return spring. The lower end of the jack is connected with a hollow upper moving mold capable of being sleeved outside the core mold. In the invention, the quality of the produced high-pressure asbestos pad is improved; the processed high-pressure asbestos pad completely matches the size of joints of a gate valve and a grouting tube flange, has good seal effect and very standard appearance, and is good-looking and wearable; the hydraulic press molding machine is convenient to operate, saves time and labor during manufacturing process, has more than 60-times of work efficiency compared with the manual manufacture method, and saves a great number of labor and time.
Description
Technical field: the present invention relates to a kind of process equipment, relate in particular to a kind of fluid pressure type high pressure asbestos pad molding press that is used to process the sealing gasket that between the pressure piping flange, uses.
Background technology:
Visit in the normal work on anti-Young Pioneer's Day at mine, contact a large amount of pressure pipings, 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, and the past leans on always and manually copies asbestos pad the size of original asbestos pad to shear off with scissors, and then with iron hammer the inner core of asbestos pad is pounded, method is very original, it is suitable coarse to do manual work, and the most important is exactly consuming time too big, wastes a large amount of time.
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 invention is to provide 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.
Technical scheme of the present invention 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 and equates with down moving.
The positioning sleeve internal diameter equates with the external mold internal diameter.
Core is cylindric or cylindric.
Good effect of the present invention is:
1, improved the quality of making the high pressure asbestos pad; High pressure asbestos pad after the processing is fully according to the interface size of gate valve and Grouting Pipe ring flange, good sealing effect, and profile is standard very, and is attractive and durable.
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 invention.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing:
As seen from Figure 1: the present invention 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.
