Description

Technical Field

[0001] The utility model relates to the technical field of linear ingot casting machines, in particular to an automatic vibration demoulding device for a zinc alloy linear ingot casting machine. Background Art

[0002] The zinc alloy linear ingot casting machine is a device used to produce zinc alloy ingots. The zinc alloy material is heated to a liquid state through a smelting furnace and then discharged from a pipeline position. The linear ingot casting machine transports multiple molds so that the multiple molds on the linear ingot casting machine continuously pass through the pipeline outlet position in turn. The liquid zinc alloy discharged from the pipeline enters the mold and then forms a solid zinc alloy ingot through a cooling and solidification process. After cooling and solidification, the zinc alloy ingot needs to be taken out of the mold.

[0003] To this end, the patent with announcement number CN213317562U discloses a novel zinc alloy continuous casting line demoulding device, including a base, a first support plate, a fixed block, a rotating shaft, a vibrating hammer, a vibrating arm, a spring module, a motor, a transmission wheel, a first fixed ring, a connecting rod, a hinge and a module; the first support plate is arranged on the base, the top of the first support plate is horizontally provided with a second support plate, the fixed block is arranged on the second support plate, one end of the vibrating arm is connected to the bottom of the fixed block by a rotating shaft, the other end of the vibrating arm is connected to the vibrating hammer, the two ends of the spring module are respectively connected to the vibrating arm and the fixed block, the motor is arranged on the second support plate, the output end of the motor is connected to the transmission wheel, and one end of the transmission wheel protrudes outward, the first fixed ring is arranged at one end of the transmission wheel protruding outward, and the second first fixed ring is arranged on the vibrating arm. The utility model can effectively demould by hammering and vibrating, which reduces labor and improves production efficiency. In addition, it can also quickly cool down and shape the demoulding alloy, which is convenient for operators to collect.

[0004] The above patent sets up structures such as a vibrating hammer, a vibrating arm, a spring module and a motor, and uses a motor to drive the vibrating arm to move, and the vibrating arm drives the vibrating hammer to strike the zinc alloy ingot in the mold to achieve separation of the zinc alloy ingot from the mold. Then, after the mold is operated to an opening-facing state, the zinc alloy ingot falls out of the mold. However, the zinc alloy ingot is usually in a brittle state after cooling and solidification, and is particularly susceptible to external forces. If the ingot is struck during the demolding process, the surface of the ingot may be damaged or the shape may be deformed. When the zinc alloy ingot is demolded by striking the zinc alloy ingot in the mold with a vibrating hammer, the zinc alloy ingot is easily stuck in the mold after being deformed by the strike. When the mold opening faces downward, it is still difficult to fall out of the mold. The success rate of demolding needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The utility model discloses an automatic vibration demoulding device for a zinc alloy linear ingot casting machine, comprising a machine body 1 and a mold 2. The machine body 1 is a linear ingot casting machine. A vibration mechanism 3 is arranged inside the machine body 1. The vibration mechanism 3 is used for vibration demoulding of the zinc alloy ingot in the mold 2. During the process of the machine body 1 conveying the mold 2, when the mold 2 is in a downward opening state, the vibration mechanism 3 is started to vibrate and demould the zinc alloy ingot in the downward opening mold 2. The vibration mechanism 3 comprises a motor 301. The motor 301 can be used in conjunction with the machine body 1. During the process of the machine body 1 conveying the mold 2, when the mold 2 is in a downward opening state, the vibration mechanism 3 is started to vibrate and demould the zinc alloy ingot in the downward opening mold 2. In the intermittent motion state, because the liquid zinc alloy needs to be injected into the mold 2, when the mold 2 receives the liquid zinc alloy, the other molds 2 are in a stopped motion state. After the mold 2 receives the liquid zinc alloy, the machine body 1 continues to transport the mold 2, so that the other molds 2 pass through the liquid zinc alloy discharge position in turn. The vibration mechanism 3 is used for automatic vibration when the mold 2 with the opening facing downward is in a stopped state. The zinc alloy ingot in the mold 2 with the opening facing downward is in a state after cooling and solidification. The internal rotation of the machine body 1 is connected with a winding shaft 302, and the winding shaft 302 can be rotatably connected with the machine body 1 through a shaft seat. The shaft seat makes the rotation of the winding shaft 302 more stable and smooth. The surface of the body 1 is fixedly connected with the motor 301. The power supply mode of the motor 301 is an external power supply. At the same time, the motor 301 can adopt a double closed-loop control mode of PLC plus frequency converter plus motor encoder. The frequency converter adopts closed-loop vector control with encoder. The frequency converter is installed with a PG card to collect the speed of the motor 301. At the same time, the pulse output end on the PG sends the pulse number of the encoder to the analog input end of the PLC. The pulse number of the encoder is calculated by the PLC program to confirm the number of revolutions of the motor 301. When the motor 301 When the number of turns is about to reach the required number of turns, the frequency converter controls the motor 301 to decelerate. After the motor 301 reaches the required number of turns at an extremely low speed, the motor 301 is controlled to stop. By controlling the number of turns of the winding shaft 302 driven by the motor 301, the steel wire rope 303 drives the square bar 307 to move upward to the set height and then stops moving. The end of the output shaft of the motor 301 is fixedly connected to the end of the winding shaft 302, and the surface of the winding shaft 302 is fixedly connected to one end of the steel wire rope 303. When the motor 301 is running, it provides a rotational driving force for the winding shaft 302 to reel in the steel wire rope 303.

[0024] The interior of the machine body 1 is fixedly connected with a square plate 304, the top of the square plate 304 is rotatably connected with a roller 305, the wire rope 303 passes through the square plate 304 and is movably connected with the inner wall of the roller 305, the roller 305 provides rolling support for the turning of the wire rope 303, and the same wire rope 303 is provided with rolling support for the turning of the wire rope 303 by two rollers 305, and the other end of the wire rope 303 is fixedly connected with a square bar 307, the square bar 307 is located below the square plate 304, and the bottom of the square bar 307 is fixedly connected with a square bar 307. A rapping block 308 for rapping the mold 2 is fixedly connected to the square bar 307, a spring 306 is fixedly connected between the square bar 307 and the square plate 304, the wire rope 303 is located inside the spring 306, and the spring 306 is compressed to provide power for the rapping block 308 to rap the mold 2. After the square bar 307 moves upward to a set height, the motor 301 stops running, and the spring 306 is in a compressed state. At this time, the square bar 307 drives the rapping block 308 to move downward quickly under the elastic force of the spring 306, as shown in FIG. Figure 3 As shown, the rapping block 308 raps and knocks the top of the mold 2 with the opening facing downward, thereby rapping the mold 2. After rapping, the adhesion between the mold 2 and the zinc alloy ingot is reduced, and the mode of reducing the adhesion by rapping is combined with the effect of the weight of the zinc alloy ingot itself to realize the demoulding of the zinc alloy ingot. After the rapping is completed, the motor 301 can also be operated in the above-mentioned control mode to reel the steel wire rope 303, so that the square bar 307 and the rapping block 308 move upward and separate from the mold 2 to prevent them from affecting the normal operation of the mold 2;

[0025] A guide assembly 4 is provided on the top of the square bar 307, and the guide assembly 4 is used for guiding the square bar 307 when it moves vertically.

[0026] Specifically, the top of the square plate 304 is fixedly connected with a connecting seat 310 , and the roller 305 is movably sleeved on the surface of a rotating shaft fixedly connected to the inner wall of the connecting seat 310 .

[0027] In this implementation plan, please refer to Figure 2 When the roller 305 rotates, it rotates around the rotating shaft on the inner wall of the connecting seat 310 , and the roller 305 provides rolling support for the turning of the wire rope 303 .

[0028] Specifically, there are two steel wire ropes 303 , and the two steel wire ropes 303 are respectively located near two ends of the square bar 307 .

[0029] In this implementation plan, please refer to Figure 3 During the winding process of the two steel wire ropes 303 , the two ends of the square bar 307 are driven to move upward at the same time. The cooperation of the two steel wire ropes 303 makes the movement of the square bar 307 more stable.

[0030] Specifically, a baffle 309 is fixedly sleeved on the surface of the reel 302 , and the wire rope 303 is located between two adjacent baffles 309 .

[0031] In this implementation plan, please refer to Figure 4 The baffle 309 limits the winding of the steel wire rope 303 and prevents the steel wire rope 303 from winding in a disorderly manner.

[0032] Specifically, there are three rapping blocks 308 , and the bottom of the rapping block 308 is hemispherical.

[0033] In this implementation plan, please refer to Figure 3 The three rapping blocks 308 are evenly spaced and distributed at the top of the mold 2 with the opening facing downward. The mold 2 is rapped together by the three rapping blocks 308. Combined with the hemispherical shape of the bottom of the rapping blocks 308, the hemispherical shape can concentrate the impact force on a small surface area, increasing the pressure, thereby increasing the impact force of the rapping blocks 308 on the mold 2, thereby ensuring the effective removal of the adhesion between the mold 2 and the zinc alloy ingot.

[0034] Specifically, the guide assembly 4 includes a guide sleeve 402, and two guide columns 401 are fixedly connected to the top of the square bar 307. The two guide columns 401 are respectively located near the two ends of the square bar 307. The guide sleeve 402 is fixedly connected to the bottom of the square plate 304, and the surface of the guide column 401 is slidably connected to the inner wall of the guide sleeve 402.

[0035] In this implementation plan, please refer to Figure 3 When the square bar 307 moves, it drives the guide column 401 to move along the inner wall of the guide sleeve 402. The guide sleeve 402 guides the movement of the guide column 401 and the square bar 307, so that the vertical movement of the square bar 307 and the rapping block 308 is more stable and smooth.

[0036] The working principle and use process of the utility model are as follows: when in use, the output shaft of the motor 301 rotates to drive the winding shaft 302 to rotate, and the winding shaft 302 is used to reel the wire rope 303, so that the wire rope 303 drives the roller 305 to rotate and the wire rope 303 drives the square bar 307 to move upward, and the square bar 307 moves upward and squeezes the spring 306, and the spring 306 is in a compressed state. The wire rope 303 reels the wire rope 303 through the winding shaft 302 to make the square bar 307 move upward to a set height, and then the motor 301 stops running. At this time, the square bar 307 drives the rapping block 308 to move downward quickly under the elastic force of the spring 306, and the rapping block 308 knocks the top of the mold 2 with the opening downward, and the rapping of the mold 2 by the rapping block 308 generates vibration, and the vibration is transmitted to between the mold 2 and the zinc alloy ingot, reducing the distance between the mold 2 and the zinc alloy ingot. The adhesion between them is reduced by rapping and combined with the weight of the zinc alloy ingot itself to achieve separation of the mold 2 and the zinc alloy ingot. At the same time, the zinc alloy ingot will not be directly hit during rapping to prevent deformation of the zinc alloy ingot. When the square bar 307 moves downward, the winding shaft 302 will be driven to rotate in the opposite direction through the wire rope 303, and the winding shaft 302 will drive the output shaft of the motor 301 to rotate in the opposite direction. When the square bar 307 moves, it drives the guide column 401 to move along the inner wall of the guide sleeve 402, and the guide sleeve 402 guides the movement of the guide column 401 and the square bar 307, so that the vertical movement of the square bar 307 and the rapping block 308 is smoother and smoother. The roller 305 is installed on the square plate 304 through the connecting seat 310, and the rolling support of the wire rope 303 is realized by the roller 305, and the steering of the wire rope 303 is realized by the rolling support.
