Abstract
The utility model discloses a pressure disk for testing the leakage of a conical punch, which comprises a fixed plate (1), screw holes (2), an elbow (4), a pressure gauge (5), a ball valve (6), a round groove (8), an air inlet hole (9) and a positioning ring (10), wherein the sizes and positions of the four screw holes (2) is consistent with those of four screw holes on a punch upper punch handle (11), and a section of the elbow (4) is welded at the upper end of the air inlet hole (9); one end of the elbow (4) is welded on the air inlet hole (9), and the other end of the elbow (4) is connected with the pressure gauge (5); the other end of the pressure gauge (5) is connected with the ball valve (6), and the other end of the ball valve (6) is connected with a quick-change connector (7); and the round groove (8) is arranged on the lower end surface of the fixed plate (1). The pressure disk can test the leakage of the conical punch, effectively prevent the conical punch from producing water leakage failure when in use, and prevent the cooling water of the male mould from leaking before the conical punch is put on a press.
Description
(1) technical field:
The utility model relates to a kind of pressure disc, especially a kind of pressure disc that is used to check sealing.
(2) background technology:
In CRT glass bulb production run, awl punch inside all adopts water as heat eliminating medium, and punch is cooled off.But because punch constantly is subjected to thermal shock in pressing process, punch will deform inevitably, makes to combine not sternly between punch body and the punch holder faying face, causes the chilled water leakage; The aging etc. of the distortion of punch holder screw, sealing gasket equally also can cause chilled water to reveal in addition, thereby punch can't normally be used and machine down.In the prior art, the colleague does not also have the device that a kind of effective prevention chilled water is revealed both at home and abroad, does not have a kind of effective method that the punch sealing is tested in other words, the punch chilled water is revealed stopped before last press.Awl punch alleged in the utility model is existing, and the utility model has mainly provided a kind of pressure disc that is used to check awl punch sealing.
(3) utility model content:
The purpose of this utility model is to provide a kind of pressure disc that is used to check sealing, uses this pressure disc awl punch water leakage fault can be stopped before last press.
For achieving the above object, the technical solution adopted in the utility model is: comprise fixed head 1, screw hole 2, bend pipe 4, tensimeter 5, ball valve 6, round groove 8, air admission hole 9 and locating ring 10, air admission hole 9 is positioned at fixed head 1 central authorities, 4 screw holes 2 and punch are the size of 4 screw holes on 11, position consistency, one section bend pipe 4 of air admission hole 9 upper ends weldering, bend pipe 4 one ends connect air admission hole 9, bend pipe 4 other ends are connected with tensimeter 5, tensimeter 5 other ends connect ball valve 6, ball valve 6 other ends connect hydraulic quick coupler 7, be provided with round groove 8 in fixed head 1 lower surface, be equipped with round O-ring seal in the round groove 8, fixed head 1 lower surface and punch fit tightly 11 end faces, punch the inlet opening on 11 and apopore position within round groove 8 and punch are 11 composition surfaces, be provided with locating ring 10 in fixed head 1 lower surface outer rim, fixed head 1 upper surface is provided with suspension ring 3.
The disclosed pressure disc of the utility model, the punch chilled water can be revealed and stop before press on the awl punch, stablized awl punch production process, improved the quality of awl punch, reduced the rejection rate of awl punch, in awl punch process, adopt this pressure disc, can reduce the production cost of awl punch.

Fig. 1 is the utility model pressure disc front elevation.
Fig. 2 is the utility model pressure disc vertical view.
Fig. 3 is the utility model pressure disc upward view.
Fig. 4 is the utility model pressure disc work synoptic diagram.
(5) embodiment:
Below in conjunction with accompanying drawing content of the present utility model is described in further detail:
Referring to Fig. 1,2,3,4, pressure disc comprises fixed head 1, screw hole 2, bend pipe 4, tensimeter 5, ball valve 6, round groove 8, air admission hole 9 and locating ring 10,4 screw holes 2 and punch are the size of 4 screw holes on 11, position consistency, one section bend pipe 4 of air admission hole 9 upper ends weldering, bend pipe 4 one ends connect air admission hole 9, bend pipe 4 other ends are connected with tensimeter 5, tensimeter 5 other ends connect ball valve 6, ball valve 6 other ends connect hydraulic quick coupler 7, be provided with round groove 8 in fixed head 1 lower surface, be equipped with round O-ring seal in the round groove 8, fixed head 1 lower surface and punch fit tightly 11 end faces, punch within round groove 8 and punch are 11 composition surfaces, is provided with locating ring 10 to the inlet opening on 11 and apopore position in fixed head 1 lower surface outer rim, and fixed head 1 upper surface is provided with suspension ring 3.
Earlier pressure disc is carried out Leakage Test, guarantee that the connection between each parts of pressure disc is air tight, pressure disc energy operate as normal, again punch is carried out Leakage Test, the method of inspection is as follows: at first, this pressure disc is fixed on the punch that processes 4 screws on 11 end faces are corresponding with 4 screws and punch, secondly, from hydraulic quick coupler 7 to the logical pressure-air of going up of punch, pressure-air will be along hydraulic quick coupler 7, ball valve 6, bend pipe 4, air admission hole 9 enters punch by the inlet opening on the punch, stop a moment, ball valve 6 is closed, write down tensimeter 5 readings, after 2-10 minute, observe tensimeter 5 readings once more, see whether tensimeter 5 front and back readings change,, illustrate that the punch sealing is good if reading is constant, during normal use can not leak, if the front and back reading changes, the punch poor sealing is described, can leak in normal the use.If find that punch during normal use can leak, then punch should be opened, search leakage cause, and eliminating water leakage fault, continue to do leak check by above method again, till tensimeter 5 front and back readings are constant, illustrate that this punch is water-tight, sealing is good, can operate as normal.
