Description

Technical Field

[0001] This utility model relates to the field of quenching furnace technology, specifically a feeding structure for a quenching furnace. Background Technology

[0002] A quenching furnace is a furnace used to heat workpieces before quenching. Quenching involves placing the workpiece in the furnace and heating it to a quenching temperature above the critical point and holding it for a period of time. Then, the workpiece is quickly removed from the furnace and placed into a quenching liquid for quenching. The heat source for the furnace can be electricity or fuel, and the temperature can be measured using thermocouples. Steel plates need to be quenched during the production process to improve their hardness and wear resistance.

[0003] Chinese patent CN221166626U discloses a feeding structure for a quenching furnace. This patent discloses a technical solution to improve feeding efficiency and solves the problem that when quenching steel plates, workers generally need to manually feed the steel plates into the quenching furnace, which requires a bottom-up process, which is very inconvenient and affects work efficiency. In addition, the temperature around the quenching furnace is also high, which can easily burn workers and is very unsafe.

[0004] When in use, the device transports the processed material to the quenching furnace in batches through the feeding mechanism, which improves the feeding efficiency. However, the processed material falls directly onto the displacement plate, which is prone to collision with the displacement plate, thereby damaging itself and the displacement plate and reducing the effect of use. Therefore, a feeding structure for the quenching furnace is proposed to solve the above problems. Utility Model Content

[0009] Furthermore, the two sliding plates are slidably connected to the two sliding grooves respectively, and the two sliding plates are located on the left and right sides of the spring respectively.

[0010] Furthermore, the buffer plate and the feed box are slidably connected, and the telescopic rod consists of a sleeve and a moving rod. One end of the moving rod passes through and extends into the interior of the sleeve. A limiting block located inside the sleeve is fixedly connected to the outside of the moving rod.

[0011] Furthermore, the pushing assembly includes an electric push rod, which is fixedly installed on the right side of the mounting plate. The output end of the electric push rod passes through the mounting plate and extends to its left side. A connecting groove is provided on the right side of the feed box, and a push plate is placed inside the connecting groove.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 The feeding structure for a quenching furnace in this embodiment includes a quenching furnace feeding structure body 1, a feeding box 2 disposed on the quenching furnace feeding structure body 1, and a feeding mechanism 3. The feeding box 2 is fixedly connected to the right side of the feeding mechanism 3.

[0022] A telescopic rod 12 is fixedly connected inside the feed box 2. A buffer plate 9 is fixedly connected to the top surface of the telescopic rod 12. A spring 13 is fitted on the outer peripheral wall of the telescopic rod 12 and is fixedly connected to the feed box 2 and the buffer plate 9 respectively. A discharge chute 8 is opened on the left side of the feed box 2. An installation plate 5 is fixedly connected to the right side of the feed box 2. Two sliding grooves 11 are opened on the inner wall of the back of the feed box 2. Two sliding plates 10 are fixedly connected to the bottom surface of the buffer plate 9, with one end extending into the sliding groove 11.

[0023] Among them, two sliding plates 10 are slidably connected to two sliding grooves 11 respectively, and the two sliding plates 10 are located on the left and right sides of the spring 13 respectively. The buffer plate 9 and the feed box 2 are slidably connected. The telescopic rod 12 consists of a sleeve and a moving rod. One end of the moving rod passes through and extends into the inside of the sleeve. A limiting block located inside the sleeve is fixedly connected to the outside of the moving rod. A through hole adapted to the moving rod is opened on one side of the sleeve.

[0024] It should be noted that the quenching furnace feeding structure body 1 and the feeding mechanism 3 are both conventional devices known to the public in the prior art, and their specific structures and working principles will not be described in detail in this article.

[0025] Specifically, the material plate enters the feed box 2 and falls downwards, then comes into contact with the buffer plate 9. Under the impact force, the buffer plate 9 moves downwards, squeezing the telescopic rod 12 and the spring 13, causing the telescopic rod 12 and the spring 13 to contract. The impact force is reduced by the action of the spring 13, and the telescopic rod 13 supports the spring 13, improving the stability of the spring 13. The sliding connection between the sliding plate 10 and the sliding groove 11 supports the buffer plate 9, improving the stability of the buffer plate 9. After the spring 13 returns to its original position, the material plate and the discharge chute 8 are located on the same center line.

[0026] In this embodiment, the mounting plate 5 is equipped with a pushing assembly, which includes an electric push rod 6. The electric push rod 6 is fixedly installed on the right side of the mounting plate 5. The output end of the electric push rod 6 passes through the mounting plate 5 and extends to its left side. The right side of the feed box 2 is provided with a connecting groove 14. A push plate 4 is placed inside the connecting groove 14. The output end of the electric push rod 6 is fixedly connected to the push plate 4. The right side of the mounting plate 5 is provided with two support holes 15. A rubber ring 16 is fixedly connected inside each of the two support holes 15. The right side of the push plate 4 is fixedly connected with two support rods 7, one end of which passes through the rubber ring 16 and extends to the right side of the mounting plate 5.

[0027] The mounting plate 5 is an L-shaped plate. A through hole is provided on the right side of the mounting plate 5. The output end of the electric push rod 6 passes through the through hole and is fitted with it with a clearance. The support rod 7 and the rubber ring 16 are attached to each other. The two support holes 15 are located at the top and bottom of the through hole, respectively.

[0028] It should be noted that the electric actuator 6 is a conventional device known to the public in the existing technology, and its specific structure and working principle will not be described in detail in this article.

[0029] Specifically, the material plate and the discharge trough 8 are located on the same center line. When the electric push rod 6 is activated, the output end of the electric push rod 6 drives the push plate 4 to move. The push plate 4 and the material plate are in contact, so that the material plate passes through the discharge trough 8 and enters the interior of the feeding mechanism 3. The push plate 4 is supported by the contact between the support rod 7 and the rubber ring 16, which improves the stability of the push plate 4.

[0030] The working principle of the above embodiments is as follows:

[0031] The material plate enters the feed box 2 and falls downwards, then comes into contact with the buffer plate 9. Under the impact force, the buffer plate 9 moves downwards, squeezing the telescopic rod 12 and the spring 13, causing them to contract. The spring 13 reduces the impact force and supports the spring 13, improving its stability. The sliding connection between the sliding plate 10 and the sliding groove 11 supports the buffer plate 9, further improving its stability. After the spring 13 returns to its original position, the material plate and the discharge chute 8 are on the same center line. The electric push rod 6 is activated, and its output end drives the push plate 4 to move. The push plate 4 comes into contact with the material plate, allowing it to pass through the discharge chute 8 and enter the feed mechanism 3. The support rod 7 and the rubber ring 16 support the push plate 4, improving its stability.

[0032] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
