Description

Technical Field

[0001] The utility model relates to a die for producing a metal ceramic tube, in particular to a core shaft cleaning device in the die for producing a metal ceramic tube. Background Art

[0002] The metal ceramic tube is a composite material composed of metal and ceramic, which has the advantages of low density, high hardness, wear resistance and good thermal conductivity.

[0003] The die used to produce metal ceramic tubes includes a base, a mandrel fixedly installed at the center of the top surface of the base, a rubber sleeve sleeved outside the mandrel and placed on the top surface of the base, and a pressure cap placed on the top of the rubber sleeve. The process of producing metal ceramic tubes is: first, put the metal ceramic powder between the mandrel and the rubber sleeve, then buckle the pressure cap on the top surface of the rubber sleeve, and then put the die filled with metal ceramic powder into the isostatic press. The isostatic press clamps the die up and down and applies air pressure to the rubber sleeve to shrink the rubber sleeve. The metal ceramic powder in the rubber sleeve is compressed into a metal ceramic tube under the extrusion of the rubber sleeve.

[0004] The die used to produce metal ceramic tubes is a reusable die. In order to ensure the surface quality of the metal ceramic tube, the surface of the core shaft in the die of the metal ceramic tube needs to be cleaned after each metal ceramic tube is produced. The traditional way to clean the surface of the core shaft in the die is to use a brush to manually clean it. This manual cleaning method has high labor intensity and slow cleaning speed, which cannot meet the production rhythm of metal ceramic tubes, resulting in low production efficiency of metal ceramic tubes. Summary of the invention

[0005] The utility model is to solve the above technical problems and provide a cleaning device for the core shaft in a metal ceramic tube die, which can reduce the labor intensity of workers, increase the cleaning speed, meet the production rhythm of metal ceramic tubes, and improve the production efficiency of metal ceramic tubes.

[0006] The technical solution of the utility model is:

[0007] A cleaning device for the core shaft of a metal ceramic tube die comprises a frame, and its special features are: a translation frame that slides forward and backward and a translation driving mechanism that drives the translation frame to move are installed on the frame, a lifting frame that slides up and down and a lifting driving mechanism that drives the lifting frame to move are installed on the translation frame, a horizontally rotating annular turntable and a rotation driving mechanism that drives the annular turntable to rotate are installed on the lifting frame, and circumferentially arranged brushes are installed on the annular turntable.

[0008] Furthermore, the translation frame is installed on the frame via a slide, and the translation driving mechanism is a cylinder fixedly installed on the frame, and a piston rod of the cylinder is fixedly installed on the translation frame.

[0009] Furthermore, the lifting frame is installed on the translation frame through a slide, and the lifting drive mechanism includes a lifting drive motor fixedly installed on the translation frame, and a screw-nut transmission mechanism connected between the output shaft of the lifting drive motor and the lifting frame.

[0010] Furthermore, the rotary drive mechanism includes a rotary drive motor fixedly mounted on the lifting frame, and a gear transmission mechanism connected between an output shaft of the rotary drive motor and the annular turntable.

[0011] Furthermore, a dust cover with the annular turntable and the brush cover therein is fixedly installed on the lifting frame, a dust suction pipe is installed on the side of the dust cover, the dust suction pipe is connected to a vacuum cleaner, and the dust swept away by the brush is recovered by the vacuum cleaner, thereby improving the working environment.

[0012] The beneficial effects of the utility model are:

[0013] Since a translation frame that slides forward and backward and a translation driving mechanism that drives the translation frame to move are installed on the frame, a lifting frame that slides up and down and a lifting driving mechanism that drives the lifting frame to move are installed on the translation frame, a horizontally rotating annular turntable and a rotating driving mechanism that drives the annular turntable to rotate are installed on the lifting frame, and brushes arranged circumferentially are installed on the annular turntable. During the cleaning operation, the base of the metal ceramic tube die is first vertically suspended in front of the translation frame by a manipulator, and then the annular turntable is moved to the top of the core shaft of the metal ceramic tube die by the translation driving mechanism, and then the lifting driving mechanism is started to drive the annular turntable to be sleeved outside the core shaft of the metal ceramic tube die and descend to the base of the metal ceramic tube die and then rise back to the position. During the process of the annular turntable descending and rising, the brush of the rotating driving mechanism drives the brush to rotate to clean the dust on the core shaft of the metal ceramic tube die, which greatly reduces the labor intensity of workers, improves the cleaning speed, meets the production rhythm of metal ceramic tubes, and improves the production efficiency of metal ceramic tubes.

The translation driving mechanism is a cylinder 3 fixedly installed on the frame 1, and the piston rod of the cylinder 3 is fixedly installed on the translation frame 2. A lifting frame 4 that slides up and down is installed on the translation frame 2 through a slide table, and a lifting driving mechanism that drives the lifting frame 4 to move. The lifting frame 4 is installed on the translation frame 2 through a slide table. The lifting driving mechanism comprises a lifting driving motor 5 fixedly installed on the translation frame 2, and a screw and nut transmission mechanism 6 connected between the output shaft of the lifting driving motor 5 and the lifting frame 4. A horizontally rotating annular turntable 7 and a rotary drive mechanism for driving the annular turntable 7 to rotate are installed on the lifting frame 4. The rotary drive mechanism includes a rotary drive motor 8 fixedly installed on the lifting frame 4, a gear transmission mechanism 9 connected between the output shaft of the rotary drive motor 8 and the annular turntable 7, circumferentially arranged brushes 10 are installed on the annular turntable 7, a dust cover 11 for covering the annular turntable 7 and the brush 10 is fixedly installed on the lifting frame 4, and a dust suction pipe 12 is installed on the side of the dust cover 11.

[0019] During the cleaning operation, first start the vacuum cleaner connected to the dust suction pipe 12, start the rotary drive motor 8 to drive the annular turntable 7 and the brush 10 to rotate, then use the manipulator to vertically suspend the base in the metal ceramic tube mold just in front of the translation frame 2, and then start the cylinder 3 to move the annular turntable 7 to just above the core shaft of the metal ceramic tube mold, and then start the lifting drive motor 5 to drive the annular turntable 7 to be sleeved outside the core shaft of the metal ceramic tube mold and descend to the base of the metal ceramic tube mold and then rise back to its position. During the process of the annular turntable 7 descending and rising again, the rotating brush 10 cleans the dust on the core shaft of the metal ceramic tube mold and drops it into the dust cover 11. At the same time, the vacuum cleaner sucks away and recycles the dust that falls into the dust cover 11 through the dust suction pipe 12. Repeat the above operations to continuously clean the core shaft of the metal ceramic tube mold.
