Technical Field

[0002] When mass-producing daily-use ceramics, a rolling forming device is usually used to manufacture the blank, and then it is fired at high temperature.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

[0040] As Figures 1 to 4As shown in the figure, an embodiment of the present invention provides a daily-use ceramic forming device. The forming device comprises a machine base 100, a main rotating part 200, a clamping unit 300, a commutation unit 400, a rolling unit 500, a movable mold 600 and a control part. Among them, the machine base 100, the main rotating part 200, the clamping unit 300 and the commutation unit 400 are all installed on the machine base 100. The rolling unit 500 can be installed on the machine base 100 or can be independently arranged. The main rotating part 200 is used to drive the movable mold 600 to rotate. When the rolling unit 500 and the main rotating part 200 work together, the clay blank located in the movable mold 600 is rolled into a preset shape. The clamping unit 300 comprises a clamping bracket 310, a telescopic assembly 320 and multiple groups of clamping wheels 330. The clamping bracket 310 is installed at the output end of the commutation unit 400. The telescopic assembly 320 is located on the clamping bracket 310. The clamping wheels 330 are rotatably connected to the telescopic assembly 320 and the clamping wheels 330 are distributed around the movable mold 600. The telescopic assembly 320 pushes the clamping wheels 330 located around the movable mold 600 to approach each other to clamp the movable mold 600. The commutation unit 400 controls the lifting and turning of the clamping unit 300 to realize loading and unloading. When rolling the clay blank, under the control of the control part, after the main rotating part 200 rotates at a preset speed for a preset time, the commutation unit 400 drives the clamping unit 300 to lift to drive the movable mold 600 away from the main rotating part 200. After the commutation unit 400 lifts to a preset height, the main rotating part 200 is powered off and the brake 240 located in the main rotating part 200 does not start. Before the movable mold 600 containing a new clay blank is placed on the main rotating part 200, the brake 240 in the main rotating part 200 starts and controls the main rotating part 200 to stop rotating.

[0041] Specifically, in this embodiment, when performing roll forming on daily-use ceramics, first, the clamping unit 300 clamps the movable mold 600 containing a new clay blank. The commutation unit 400 controls the clamping unit 300 to move in space so that the movable mold 600 is placed on the main rotating part 200. At this time, the rolling unit 500 and the main rotating part 200 work together. The rotating arm 501 on the rolling unit 500 rotates, driving the rolling head 502 on the rotating arm 501 to move to the position of the movable mold 600. The main rotating part 200 drives the movable mold 600 to rotate. The rolling head 502 is driven to rotate by a motor structure arranged on the rotating arm 501. Under the rotation of the rolling head 502 and the main rotating part 200, the clay blank on the movable mold 600 is roll formed. After the rolling is completed (that is, after the main rotating part 200 rotates at a preset speed for a preset time), the clamping unit 300 clamps the movable mold 600 and is driven by the commutation unit 400 to disengage from the main rotating part 200. The rotating arm 501 is lifted synchronously. At this time, the power supply to the main rotating part 200 is stopped, and the main rotating part 200 naturally decelerates under the action of internal forces (such as the friction between bearing balls and the resistance of the main rotating part 200 to rotate). The commutation unit 400 moves the movable mold 600 to the blanking position, and then the clamping unit 300 releases the movable mold 600. The clamping unit 300 clamps the movable mold 600 containing a new clay blank and moves it above the main rotating part 200 under the control of the commutation unit 400. If at this time the main rotating part 200 has stopped rotating, the clamping unit 300 places the movable mold 600 on the main rotating part 200. If the main rotating part 200 is still rotating, the brake 240 in the main rotating part 200 is activated, and the brake 240 brakes the main rotating part 200 so that the main rotating part 200 stops rotating, and the clamping unit 300 places the movable mold 600 on the main rotating part 200.

[0042] In this embodiment, when the brake 240 brakes, it only brakes the main rotating part 200, and the main rotating part 200 has undergone natural deceleration when being braked. Compared with the traditional method, the wear of the brake 240 is less, reducing the maintenance frequency. At the same time, the movable mold 600 is lifted after the rolling is completed, canceling the braking process of the movable mold 600 and improving the production efficiency.

[0043] Specifically, in this embodiment, the machine base 100 is a prior art. For example, the machine base 100 is a box structure made of profiles and plates. The main rotating part 200 and the commutation unit 400 are both installed on the machine base 100, and the rolling unit 500 is a prior art.

[0044] In this embodiment, as Figure 4 and Figure 7 shown, the main rotating part 200 includes a mold base 210, a main motor 220, a transmission shaft 230, and a brake 240. The mold base 210 is a prior art. For example, the mold base 210 is a cylindrical structure with a groove structure provided on its upper end face. The mold base 210 is rotationally connected to the machine base 100 through the transmission shaft 230. The transmission shaft 230 is rotationally connected to the machine base 100 through a bearing structure. The main motor 220 is fixedly connected to the inside of the machine base 100. The output shaft of the main motor 220 is fixedly connected to the input end of the brake 240. The brake 240 is fixedly connected to the inside of the machine base 100. The output end of the brake 240 is fixedly connected to one end of the transmission shaft 230. The end of the transmission shaft 230 away from the brake 240 is fixedly connected to the mold base 210 through bolts. The movable mold 600 is placed in the groove structure on the upper end face of the mold base 210. When the main motor 220 rotates, it drives the mold base 210 to rotate, and the mold base 210 drives the movable mold 600 to rotate. The mold base 210, the main motor 220, and the transmission shaft 230 are all prior arts. The brake 240 is an electromagnetic brake in the prior art.

[0045] During braking, the brake 240 is activated. The brake 240 brakes the transmission shaft 230, causing the die holder 210 to stop rotating. When rolling the green body, the main motor 220 is powered on and starts. The main motor 220 goes through the processes of acceleration and uniform speed. After the main motor 220 rotates a preset number of turns, the clay blank is rolled into shape. At this time, the main motor 220 stops being powered on, and the movable die 600 is lifted by the commutation unit 400. The movable die 600 disengages from the die holder 210. The die holder 210 naturally decelerates under the frictional forces of the bearing structure, the brake 240, and the respective mating structures within the main motor 220. When the brake 240 brakes, the brake 240 is activated, and the braking objects of the brake 240 are the die holder 210, the transmission shaft 230, and the rotor of the main motor 220. In the case of traditional forming devices during braking, the braking objects are the die holder 210, the transmission shaft 230, the rotor of the main motor 220, and the movable die 600. Since the traditional rolling forming device needs to brake the movable die 600, the required braking force is large. At the same time, it brakes immediately after rolling is completed, and the initial braking speed is also greater than the initial speed when the brake 240 of the present application is activated. Therefore, when the brake 240 of the present application is activated, there is no need to brake the movable die 600. At the same time, after the die holder 210 naturally decelerates, the brake 240 is activated. Its braking force is small and the initial speed is small, which can greatly reduce the wear of the brake 240 and lower the maintenance frequency.

[0046] The main motor 220 is fixedly connected to the interior of the machine base 100 through the motor base 101.

[0047] Such as Figure 1 、 Figure 4 and Figure 8As shown, the clamping bracket 310 is formed by welding square pipes. The clamping bracket 310 is U-shaped. A limiting groove 311 is provided inside the clamping bracket 310. The telescopic assembly 320 is connected to the clamping bracket 310. The telescopic assembly 320 includes a wheel bracket 321 and a telescopic member 322. The telescopic member 322 is fixedly connected to the outside of the clamping bracket 310. The output shaft of the telescopic member 322 passes through the clamping bracket 310 and is fixedly connected to the wheel bracket 321. The telescopic member 322 is a pneumatic telescopic cylinder. The wheel bracket 321 is slidably connected inside the limiting groove 311. A wheel seat 323 is provided on the wheel bracket 321. The clamping wheel 330 is rotatably connected to the wheel seat 323. In this embodiment, two wheel seats 323 are provided on each wheel bracket 321, that is, two clamping wheels 330 are connected to each wheel bracket 321. The wheel seats 323 are located on both sides of the wheel bracket 321. The wheel bracket 321 is a groove-shaped structure formed by fixing an angle steel and a plate through bolts. Both ends of the clamping wheel 330 are rotatably connected to the wheel seat 323 through bearings. There are two wheel brackets 321. When clamping the movable mold 600, the output shaft of the telescopic member 322 extends out, causing the two wheel brackets 321 to approach each other, so that the clamping wheels 330 clamp the movable mold 600.

[0048] Preferably, as Figure 9 and Figure 10 shown, the movable mold 600 is a conical structure. The movable mold 600 is provided with a forming groove 601, a connecting surface 602 and a clamping edge 603. The forming groove 601 is used to hold the clay blank. At the same time, the inner wall of the forming groove 601 and the rolling head 502 act together to form the ceramic clay blank. The connecting surface 602 cooperates with the groove structure in the mold base 210. The connecting surface 602 is a conical surface. The clamping edge 603 is located at the edge position of the mouth of the forming groove 601. The clamping edge 603 is an annular protrusion. A clamping groove 331 is provided on the clamping wheel 330. The clamping groove 331 cooperates with the clamping edge 603, so that the clamping wheel 330 can limit the movable mold 600 to prevent the movable mold 600 from falling.

[0049] As a preferred implementation manner in this embodiment, during the process of rolling and forming the clay blank, the clamping wheel 330 always clamps the movable mold 600, thereby eliminating the time for re-clamping and improving work efficiency.

[0050] As a preferred implementation manner in this embodiment, as Figure 8As shown, a motor sleeve 324 is further provided on the wheel carrier 321. A generator 340 is fixedly connected inside the motor sleeve 324. The output shaft of the generator 340 is fixedly connected to the clamping wheel 330. When the clamping wheel 330 rotates, it drives the rotor of the generator 340 to rotate. The generator 340 is also electrically connected to a control switch and an energy storage device. When the movable mold 600 disengages from the mold base 210, the control switch connected to the generator 340 closes the circuit of the generator 340 and the energy storage device. The generator 340 recovers the rotational energy of the movable mold 600 and at the same time decelerates the movable mold 600, so that the movable mold 600 containing the ceramic blank stops rotating before being placed in the next process. The generator 340 is fixedly connected to the inside of the motor sleeve 324 by adhesion or screws. The energy storage device is a prior art, and the energy storage device includes circuits such as rectification, inversion, and voltage stabilization, which are used to process the current generated by the generator 340 to form a circuit with stable voltage and current, and then store it in the energy storage device.

[0051] It should be noted that during the process of rolling and forming the mud blank, the control switch connected to the generator 340 is turned off, so as to reduce the resistance of the generator 340 to the clamping wheel 330.

[0052] As a preferred implementation mode in this embodiment, as Figures 4 to 8As shown, the commutation unit 400 includes a lead screw 410, a slider 420, a commutation motor 430, a fixed limit block 440, a movable limit block 450, and a lifting member 460. The lead screw 410 is rotatably connected to the machine base 100. One end of the lead screw 410 is rotatably connected to the machine base 100, and a retaining piece 411 is fixedly connected to the end of the lead screw 410 away from the machine base 100. The slider 420 is a long strip-shaped block structure and is connected to the lead screw 410 by threads. The commutation motor 430 is fixedly connected to the inside of the machine base 100 and is fixedly connected to the end of the lead screw 410. The commutation motor 430 is used to drive the lead screw 410 to rotate. The fixed limit block 440 is fixedly connected to the machine base 100 and is located on both sides of the slider 420 for limiting the slider 420. One end of the fixed limit block 440 is fixedly connected to the machine base 100. Both the lead screw 410 and the fixed limit block 440 are vertically arranged. The movable limit block 450 is located at the end of the fixed limit block 440 away from the lead screw 410. The cross-section of the movable limit block 450 is the same as that of the fixed limit block 440, so that when the movable limit block 450 contacts the end of the fixed limit block 440, the surface of the fixed limit block 440 in contact with the slider 420 and the surface of the movable limit block 450 in contact with the slider 420 are coplanar. A limit shaft 441 is provided at the end of the fixed limit block 440, and the movable limit block 450 is sleeved on the limit shaft 441, enabling the movable limit block 450 to slide up and down. The lifting member 460 is fixedly connected to the fixed limit block 440, and the output end of the lifting member 460 is fixedly connected to the movable limit block 450. When the output end of the lifting member 460 extends, the movable limit block 450 slides upward; when the output shaft of the lifting member 460 retracts, the movable limit block 450 slides downward. When the lifting member 460 retracts, the distance between the upper end surface of the movable limit block 450 and the retaining piece 411 is the same as the thickness of the slider 420.

[0053] Specifically, at least two thrust bearings 413 are sleeved on the part of the lead screw 410 located inside the machine base 100. The thrust bearings 413 are fixedly connected to the inside of the machine base 100 through bearing seats 102. The reversing motor 430 is fixedly connected to the inside of the machine base 100 by bolts. The output shaft of the reversing motor 430 is fixedly connected with a speed reducer 431. The output shaft of the speed reducer 431 is fixedly connected to the lead screw 410. The reversing motor 430 drives the lead screw 410 to rotate through the speed reducer 431. The slider 420 has a square structure. A lead screw nut structure is arranged inside the slider 420. The slider 420 is threadedly connected to the lead screw 410. The fixed limit block 440 has an L-shaped structure. The short end of the slider 420 is fixedly connected to the machine base 100 by bolts. The long end of the fixed limit block 440 is vertically arranged. The fixed limit block 440 is located on both sides of the slider 420 and is in contact with the slider 420. When the fixed limit block 440 and the slider 420 are in contact, the slider 420 can only move up and down. The limit shaft 441 has a round rod structure. The limit shaft 441 is fixedly connected to one end of the fixed limit block 440 away from the machine base 100 by threads. At least two mutually parallel limit shafts 441 are arranged on each fixed limit block 440. The movable limit block 450 is provided with a through hole structure matching the limit shaft 441, so that the movable limit block 450 is slidably connected to the limit shaft 441. The lifting member 460 is a pneumatic telescopic rod. The cylinder body of the lifting member 460 is fixedly connected to the fixed limit block 440 by bolts. The output shaft of the lifting member 460 is fixedly connected to the movable limit block 450 by a nut structure. The retaining piece 411 is located at the end of the lead screw 410. The end of the lead screw 410 is threadedly connected with a fastening nut 412. When the fastening nut 412 is tightened at the end of the retaining piece 411, the fastening nut 412 presses the retaining piece 411 against the end of the lead screw 410.

[0054] Such as Figure 5 and Figure 6As shown, when the clamping unit 300 moves vertically up and down, such as when controlling the movable mold 600 to disengage from the mold base 210 or placing the movable mold 600 onto the mold base 210, the slider 420 slides between the fixed limit blocks 440. At this time, the movable limit block 450 contacts the end of the fixed limit block 440, and the output shaft of the lifting member 460 retracts. When the slider 420 slides to the top of the lead screw 410, the slider 420 cannot continue to slide upward. At this time, the slider 420 rotates following the lead screw 410. When the slider 420 rotates to a preset angle, such as 180 degrees, the output shaft of the lifting member 460 extends, the movable limit block 450 slides to both sides of the slider 420, the lead screw 410 rotates in the reverse direction, the slider 420 cannot rotate following the lead screw 410, and the slider 420 slides downward along the movable limit block 450, thereby completing the commutation work of the clamping unit 300.

[0055] It should be noted that, as another implementation manner in this embodiment, when there are multiple rotation angles of the slider 420, such as three, at least three groups of the fixed limit blocks 440 and the movable limit blocks 450 are provided to realize the rotation of the slider 420 at multiple angles.

[0056] Embodiment 2

[0057] As Figure 11 As shown, as another embodiment of the present invention, the difference between this embodiment and Embodiment 1 is that two clamping units 300 are provided, and the two clamping units 300 are located at both ends of the slider 420, so that the clamping units 300 can clamp the two movable molds 600 simultaneously during the up and down movement;

[0058] At this time, the loading position and the unloading position of the movable mold 600 are at the same place. After the staff takes away the rolled and formed ceramic assembly, a new green body is placed onto the movable mold 600.

[0059] It should be noted that, in one implementation manner of this embodiment, the clamping unit 300 may not include the telescopic assembly 320. The clamping wheel 330 is directly rotatably connected to the clamping bracket 310, and the movable mold 600 is rotatably connected between the clamping wheels 330. In this embodiment, the movable mold 600 is not easy to replace, but the telescopic assembly 320 can be cancelled, and there is no need for a clamping process during the loading and unloading, improving the production efficiency.
