Description

TECHNICAL FIELD

[0001] The utility model relates to the field of ceramic powder blank, especially the adjustable pressure control device for ceramic powder blank. BACKGROUND

[0002] The ceramic body is the main body of the ceramic product, and its performance determines the performance and application of the ceramic product. The preparation of the blank is of great importance in the ceramic production process. Currently, when the blank is made, the ceramic powder is pressed. The pressure makes the powder particles close to each other and combine to form a blank with certain shape and strength.

[0003] In the dry pressing forming mode in the prior art, a hydraulic rod is often used in combination with a pressing disc to press and form the powder. However, in actual use, the following defects exist. The pressure point is the end region of the hydraulic rod. When blanks of different specifications are prepared, the corresponding pressing disc is used. When the required specification of the blank is greater than the end of the hydraulic rod, single-point pressure is applied during the pressing process. The pressure of the pressing disc and the end region of the hydraulic rod is greater than the pressure on the outside of the pressing disc, thereby causing uneven stress on the ceramic powder, which easily affects the blank-making effect. Moreover, the existing hydraulic rod pressing mode is not easy to adjust the pressing region according to the requirements of the blank, and the use mode is single.

[0004] Therefore, the adjustable pressure control device for ceramic powder blank is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0005] The purpose of the utility model is to provide the adjustable pressure control device for ceramic powder blank to solve the above problems and improve the problems of uneven stress on the ceramic powder and difficulty in adjusting the pressing region according to the requirements of the blank.

[0006] The adjustable pressure control device for ceramic powder blank comprises a hydraulic rod, a pressing disc mounted to the bottom end of the hydraulic rod, and an adjusting mechanism. The number of the adjusting mechanisms is six. The adjusting mechanisms are arranged on the outside of the hydraulic rod and are used to adjust the pressure point and the pressure region of the pressing disc. The adjusting mechanism comprises an adjustable inclined rod and an inclined pipe. One end of the inclined rod is embedded with a ball in contact with the pressing disc. One end of the inclined rod is provided with a piston plate slidingly connected to the inside of the inclined pipe.

[0007] Preferably, an annular box is arranged on the outside of the hydraulic rod. One end of the inclined pipe is hinged to the outside of the annular box. A conduit is arranged between the annular box and the inclined pipe.

[0008] Preferably, two first electric push rods are arranged on the outside of the hydraulic rod in symmetry along the axis. One end of the first electric push rod is fixedly mounted to the outside of the annular box.

[0009] Preferably, a second electric push rod extending into the interior of the annular box is mounted on the annular box, and one end of the second electric push rod is slidably connected to an annular piston disc inside the annular box.

[0010] Preferably, a spring is installed on the outside of the inclined tube, and one end of the spring is installed on the outside of the hydraulic rod.

[0011] Preferably, a solenoid valve is installed on the outside of the conduit, and the conduit is a flexible tube.

[0012] Preferably, the top of the annular box has a through hole.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting six inclined rods and matching them with hydraulic rod ends, multiple pressure points are formed. During use, the pressure position of the inclined rod ends can be adjusted according to the required blank size to make them move synchronously, improving adaptability while ensuring the uniformity of ceramic powder pressure, thus ensuring the blank making effect.

[0015] 2. By setting up solenoid valves, when different areas of the blank have pressure requirements, the solenoid valve of the area that does not need pressure can be closed during the adjustment of the position of the inclined rod, so that the end of the inclined rod does not contact the area on the pressure plate. Then, the solenoid valve of the remaining area that needs pressure can be opened, so that during the movement of the annular piston disc, the gas will push the corresponding inclined rod to contact the corresponding area on the pressure plate. Subsequently, during the operation of the hydraulic rod, the pressure on the area where the inclined rod is in contact with the pressure plate is greater, and the pressure on the area where the inclined rod is not in contact with the pressure plate is relatively smaller. The pressure area is adjusted according to the needs of the blank, and the usage is diversified. Attached Figure Description

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] In the specific implementation, as shown in the figure, Figures 1-4 The adjustable pressure control device for ceramic powder blanking comprises a hydraulic rod 100, a pressure plate 200 and an adjusting mechanism 300 installed at the bottom end of the hydraulic rod 100. The adjusting mechanism 300 is six in number and is arranged outside the hydraulic rod 100 and used for adjusting the pressure point and pressure area of the hydraulic rod 100 on the pressure plate 200. The adjusting mechanism 300 comprises an adjustable inclined rod 310 and an inclined pipe 320. One end of the inclined rod 310 is embedded with a ball 311 in contact with the pressure plate 200. One end of the inclined rod 310 is installed with a piston plate 312 slidingly connected to the inside of the inclined pipe 320.

[0023] As shown in the figure, Figure 1 , Figure 2 , Figure 3 and Figure 4 The outer side of the hydraulic rod 100 is sleeved with a ring box 110. One end of the inclined pipe 320 is hinged to the outer side of the ring box 110. The ring box 110 and the inclined pipe 320 are installed with a conduit 111 therebetween.

[0024] Before the ceramic powder blanking operation, the user can adjust the angle of the inclined rod 310 according to the required specification of the blank body. The gas in the ring box 110 is introduced into the inclined pipe 320 along the corresponding conduit 111, so that the inclined rod 310 slides in the inclined pipe 320, until the end of the inclined rod 310 is in contact with the pressure plate 200. The contact point is the pressure point. After the gas is introduced, the six pressure points of the inclined rod 310 will expand outward along the axis of the pressure plate 200, so that the appropriate pressure area can be adjusted according to the required specification of the blank body. Then the hydraulic rod 100 is started to operate, so that it drives the inclined rod 310 and the pressure plate 200 to press the ceramic powder. The end of the hydraulic rod 100 and the inclined rod 310 at multiple points are in contact with the upper part of the pressure plate 200, so that the pressure is more uniform, ensuring the blanking effect.

[0025] When the special green body is prepared, if the pressure area needs to be adjusted, the gas in the annular box 110 can be introduced into the inclined pipe 320 of the required pressurized area, so that the inclined rod 310 in the part area is in contact with the pressure plate 200, and the inclined rod 310 on the remaining area is not in contact with the pressure plate 200. During the subsequent pressure process of the hydraulic rod 100, the pressure plate 200 can form different pressures on different areas of the ceramic powder to meet the preparation of special green bodies.

[0026] As shown in Figure 1 and Figure 2 , two first electric push rods 120 are symmetrically arranged along the axis of the hydraulic rod 100, and one end of the first electric push rod 120 is fixedly installed to the outside of the annular box 110.

[0027] When the required green body size is too large, the gas-driven inclined rod 310 cannot easily meet the requirement of changing the pressure point position. At this time, the user can use the first electric push rod 120 to drive the annular box 110 to move downward, which can drive the inclined pipe 320 to move, so that the six inclined inclined rods 310 move outward on the pressure plate 200, increasing the adjustment range of the inclined rod 310 to adjust the pressure area.

[0028] As shown in Figure 2 and Figure 3 , a second electric push rod 112 extending into the inside of the annular box 110 is installed on the annular box 110, and one end of the second electric push rod 112 is installed with a ring-shaped piston disc 113 slidingly connected to the inside of the annular box 110.

[0029] Starting the second electric push rod 112 can drive the ring-shaped piston disc 113 to move, so that the gas in the annular box 110 is discharged into the inside of the inclined pipe 320.

[0030] As shown in Figure 2 and Figure 4 , a spring 321 is installed on the outside of the inclined pipe 320, and one end of the spring 321 is installed to the outside of the hydraulic rod 100.

[0031] The spring 321 is used to flexibly support the inclined pipe 320, and after each green body preparation is completed, the inclined pipe 320 can be pulled back to position, facilitating the adjustment and use of the next time.

[0032] As shown in Figure 4 , an electromagnetic valve 114 is installed on the outside of the catheter 111, and the catheter 111 is a hose, which ensures the gas guiding effect while not affecting the movement of the inclined pipe 320.

[0033] The use of the electromagnetic valve 114 can open and close the corresponding catheter 111, so as to achieve the effect of pressure partition control.

[0034] As shown in Figure 3As shown, the top of the annular box 110 is provided with a through hole.

[0035] This can make the annular piston disc 113 move, and the gas between the top of the annular piston disc 113 and the annular box 110 can normally flow with the outside, ensuring the normal movement of the annular piston disc 113.

[0036] Working principle: Before the ceramic powder is prepared, the user can adjust the angle of the inclined rod 310 according to the required specification of the embryo body, and guide the gas in the annular box 110 into the inclined pipe 320 along the corresponding conduit 111, so that the inclined rod 310 slides in the inclined pipe 320, until the end of the inclined rod 310 contacts the pressure plate 200, and the contact point is the pressure point, after the gas is introduced, the six inclined rods 310 pressure points will expand outward along the axis of the pressure plate 200, so as to adjust the appropriate pressure area according to the required specification of the embryo body, and then start the hydraulic rod 100 to operate, so as to drive the inclined rod 310 and the pressure plate 200 to press the ceramic powder, and the end of the hydraulic rod 100 and the inclined rod 310 on multiple points are in contact with the pressure plate 200 above, so that the pressure is more uniform, ensuring the embryo preparation effect; and when special embryo body is prepared, if the pressure area needs to be adjusted, the gas in the annular box 110 can be introduced into the inclined pipe 320 of the required pressure area, so that the inclined rod 310 in this part of the area is in contact with the pressure plate 200, and the inclined rod 310 in the remaining area is not in contact with the pressure plate 200, in the subsequent hydraulic rod 100 pressure process, the pressure plate 200 can form different strength pressure on different areas of the ceramic powder, meet the preparation of special embryo body, the whole device adopts multi-point pressure mode, and the pressure position can be adjusted according to the specification of the prepared embryo body, so that the ceramic powder is more uniform in stress, ensuring the embryo preparation effect, and the pressure area can be adjusted according to the embryo preparation requirement, and the use mode is diversified.

[0037] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
