Description

Technical Field

[0001] The invention relates to the technical field of ceramic sintering furnaces, in particular to a sintering furnace for ceramic production. Background Art

[0002] The brake system is an important component in a car, which can reduce the speed of the vehicle. The brake system includes a brake pedal, a brake cylinder, annular brake pads and a brake disc. When the driver steps on the brake pedal, the pedal pressurizes the brake cylinder, and the brake cylinder drives the end face of the brake pad to contact the brake disc. Due to the friction between the two, the kinetic energy of the vehicle is converted into heat energy, thereby reducing the speed of the vehicle and achieving a braking effect. Therefore, the brake pads have to withstand extremely high temperatures when working. In order to improve the performance of the brake pads, ceramic brake pads made of ceramic composite materials have appeared in the prior art. Compared with traditional metal brake pads, the wear resistance, heat resistance and lightweight of ceramic brake pads are significantly improved. When producing ceramic brake pads, high-quality ceramic powder is first mixed evenly with a binder, and then pressed into shape and then sintered in a sintering furnace.

[0003] In the prior art, when the annular brake pad after compression molding is sintered in a sintering furnace, the brake pad blank is generally placed on a support plate or fixed by a fixing rod passing through the inner side of the brake pad. During the heating and sintering process, the inner side or one end face of the brake pad is in contact with the support body for a long time, resulting in different temperatures on the surface of the brake pad during the sintering process, which is prone to large cracks and reduces the performance of the brake pad. In the prior art, when the brake pad is sintering, the annular side of the brake pad is prone to cracking under the action of bubbles. The existing device cannot repair the cracks while heating, and cannot be sintered again after repair after sintering, resulting in a high defective rate of the brake pad during sintering, resulting in a high cost of the ceramic brake pad.

When the inspection is completed, several third electric telescopic rods are extended, and the third electric telescopic rods drive the fixed tube to move upward.

[0034] The rotating rod 23 is provided with a rotating groove 210 at the end away from the second electric telescopic rod 28, and a connecting rod 211 is slidably fitted in the rotating groove 210. The end of the connecting rod 211 is arranged to rotate with the partition 24 through a thread.

[0035] Specifically, the limiting block 26 at the telescopic end of the second electric telescopic rod 28 cooperates with the limiting groove 27, and when the second electric telescopic rod 28 rotates, the rotating rod 23 can be driven to rotate.

[0036] In this embodiment, a plurality of equally spaced limiting mechanisms 6 are fixedly connected to the side surface of the rotating rod 23 .

[0037] The limiting mechanism 6 includes a plurality of fourth fixed bodies 61 fixedly connected to the side of the rotating rod 23, the plurality of fourth fixed bodies 61 are arranged equidistantly, a fourth guide groove 63 is respectively provided on both sides of the plurality of fourth fixed bodies 61, a plurality of matching rings 64 are respectively slidably fitted in the fourth guide grooves 63, a plurality of matching rings 64 are respectively provided on the side of the matching rings 64, a plurality of bolts 66 are fitted in the threaded holes 65, and a friction sleeve 62 with a large friction coefficient is fixedly connected to the side of the fourth fixed body 61.

[0038] Specifically, the matching ring 64 is moved while several bolts 66 are screwed, so that the side surfaces of two adjacent bolts 66 contact the end surface of the brake pad, thereby limiting the brake pad and preventing the brake pad from shifting during the sintering process.

[0039] In this embodiment, a detection mechanism 4 capable of detecting the side gap of the brake pad is provided between the two partitions 24 .

[0040] The detection mechanism 4 includes a fixing plate 41 fixedly arranged between two partitions 24, a second guide groove 42 is opened at the lower end of the fixing plate 41, a second motor 411 is fixedly connected in the second guide groove 42, a threaded rod 43 is fixedly connected to the transmission shaft end of the second motor 411, a third fixing body 44 which is slidably matched with the second guide groove 42 is provided on the side of the threaded rod 43, an empty groove 48 is opened at the lower end of the third fixing body 44, and a high temperature resistant pressure sensor 46 is arranged in the empty groove 48.

[0041] The lower end of the third fixed body 44 is fixedly connected with a second fixed ring 45, the lower end of the second fixed ring 45 is provided with a third guide groove 47, a third fixed ring 49 is tightly arranged in the third guide groove 47, the lower end of the third fixed ring 49 is fixedly connected with a top ring 410, and the lower end of the top ring 410 is tightly arranged with the side of the brake pad.

[0042] Specifically, the second motor 411 drives the threaded rod 43 to rotate, and the threaded rod 43 cooperates to drive the third fixed body 44 to move. The third fixed ring 49 moves to the position where the lower end of the top ring 410 contacts the side of the brake pad by rotation. When the third fixed ring 49 moves to the position overlapping with the brake pad, as the temperature rises, the value of the pressure sensor 46 gradually increases. When cracks appear on the side of the brake pad, the value of the pressure sensor 46 drops rapidly.

[0043] In this embodiment, a repair injection mechanism 3 for filling the cracks in the brake pad is disposed at the lower end of the main body shell 1 , and two symmetrically disposed support seats 5 are fixedly connected to the lower end of the main body shell 1 .

[0044] The repair injection mechanism 3 includes a plurality of second through holes 311 equidistantly opened on the end surface of the main shell 1, and the positions of the plurality of second through holes 311 correspond to the positions of the limiting mechanism 6. A first placement groove 314 communicating with the second through hole 311 is opened inside the lower end of the main shell 1, and a plurality of fourth electric telescopic rods 313 are fixedly connected in the plurality of first placement grooves 314, and the telescopic ends of the plurality of fourth electric telescopic rods 313 are fixedly connected with cut-off blocks 312 slidably matched with the first placement grooves 314, and the cross-section of the cut-off blocks 312 is larger than the cross-section of the second through hole 311.

[0045] A first fixed body 31 is correspondingly provided at the lower end of the main body shell 1 at a position close to the second through hole 311, a second placement groove 315 is opened at the upper end of the first fixed body 31, two symmetrically arranged third electric telescopic rods 33 are fixedly connected in the second placement groove 315, the telescopic ends of the two third electric telescopic rods 33 are fixedly connected with a first fixed ring 34, a fixed tube 36 is fixedly connected to the inner side of the first fixed ring 34, a second fixed body 37 is fixedly provided on the upper end of the fixed tube 36, and a discharge hole 38 is penetrated in the second fixed body 37.

[0046] The upper end of the second fixed body 37 is an arc-shaped structure that fits the brake pad. The upper end of the second fixed body 37 is provided with a first guide groove 39, and a scraper 310 is slidably arranged in the first guide groove 39. The lower end of the first fixed body 31 is fixedly connected to a feed pump 32, and the lower end of the first fixed body 31 is fixedly connected to a telescopic tube 35, the lower end of the telescopic tube 35 is connected to the feed pump 32, and the upper end of the feed pump 32 is fixedly connected to the fixed tube 36.

[0047] Specifically, several third electric telescopic rods 33 are extended, and the third electric telescopic rods 33 drive the fixed tube 36 to move upward, and the second fixed body 37 at the upper end of the fixed tube 36 contacts the side of the brake pad, and then the second electric telescopic rod 28 is extended and retracted. Since the limit block 26 is in close contact with the limit groove 27, the extension and retraction of the second electric telescopic rod 28 can drive the rotating rod 23 to move left and right. When the crack on the side of the brake pad moves to a position overlapping with the discharge hole 38, the feed pump 32 is started to move the ceramic powder to the crack, and the powder can be scraped flat by the scraper 310.

[0048] When in use, several first electric telescopic rods 25 are extended at the same time, and several first electric telescopic rods 25 drive the fixing plate 41 to move upward through the connecting block 22, and the fixing plate 41 drives the rotating rod 23 to move upward through the two partitions 24, and then the connecting rod 211 is rotated to disengage the connecting rod 211 from the partition 24, and then the formed brake pads are placed on the side of the fourth fixed body 61 in turn, and then the matching ring 64 is moved and several bolts 66 are screwed at the same time, so that the sides of two adjacent bolts 66 are in contact with the end face of the brake pad, and the brake pad is limited to prevent the brake pad from shifting during the sintering process, and then the first electric telescopic rod 25 is retracted to make the upper end of the fixing plate 41 parallel to the upper end of the main body shell 1, and then the main body shell 1 is heated by the electric heating wire, and the first motor 21 is started, and the second electric telescopic rod 25 is extended at the same time. The electric telescopic rod 28, the limit block 26 at the telescopic end of the second electric telescopic rod 28 cooperates with the limit groove 27. When the second electric telescopic rod 28 rotates, it can drive the rotating rod 23 to rotate, and the rotating rod 23 drives a number of fourth fixed bodies 61 to rotate. The side of the fourth fixed body 61 is provided with a friction sleeve 62 with a high friction coefficient. When the friction sleeve 62 rotates, since the upper end point of the friction sleeve 62 contacts the inner side of the brake pad, and the diameter of the friction sleeve 62 is smaller than the inner diameter of the brake pad, it can ensure that a number of brake pads rotate at the same time. When rotating, the inner diameters of a number of brake pads contact the fourth fixed body 61 in turn, which can ensure that the inner diameters of a number of brake pads are in contact with the hot air in the main body shell 1 during sintering for the same time, which greatly reduces the cracking of the brake pads caused by different heating times of the inner diameters, and reduces the defective rate.

[0049] During sintering, the second motor 411 is started, the second motor 411 drives the threaded rod 43 to rotate, the threaded rod 43 cooperates to drive the third fixed body 44 to move, and the third fixed ring 49 moves to the position where the lower end of the top ring 410 contacts the side of the brake pad by rotation. When the third fixed ring 49 moves to the position overlapping with the brake pad, as the temperature rises, the value of the pressure sensor 46 gradually increases. When cracks appear on the side of the brake pad, the value of the pressure sensor 46 drops rapidly. The pressure sensor 46 is connected to the computer through wires. The entire side of the brake pad can be inspected through the movement of the third fixed body 44 and the rotation of the brake pad, so that the shape of the crack on the side of the brake pad can be drawn by the computer, which is convenient for subsequent repair of the brake pad surface. When the inspection is completed, several third electric telescopic rods 33 are extended, and the third electric telescopic rods 33 drive the fixed tube 36 to move upward, and the second fixed body 37 at the upper end of the fixed tube 36 is in contact with the brake pad. After the side contact, the second electric telescopic rod 28 is extended and retracted. Since the limit block 26 is in close contact with the limit groove 27, the extension and retraction of the second electric telescopic rod 28 can drive the rotating rod 23 to move left and right. When the crack on the side of the brake pad moves to the position overlapping with the discharge hole 38, the feed pump 32 is started to move the ceramic powder to the crack. The powder can be scraped flat by the scraper 310, so that the crack on the side of the brake pad can be repaired during the sintering process to ensure the performance of the side of the brake pad after sintering, prevent the ceramic powder from being smeared on the area without cracks, and ensure that the size of the side of the brake pad is consistent after sintering.
