Description

Technical Field:

[0001] The utility model relates to the technical field of heating furnaces, and more specifically to a quantitative pushing mechanism for an intermediate frequency furnace. Background Art:

[0002] At present, bearing rings are generally processed into blanks by forging, and then finished products are obtained through machining. During the forging process of the rings, it is necessary to strictly measure the temperature of the heated rings. Otherwise, if the temperature is unqualified, ring products with the required performance cannot be obtained. Among them, unqualified rings are generally reheated and reused through an intermediate frequency furnace. Currently, rings are mainly manually placed on the feeding chute of the intermediate frequency furnace, and then manually pushed into the intermediate frequency furnace. By using the interaction force between the rings, while pushing rings into the intermediate frequency furnace, the rings inside the furnace will also be pushed out; however, due to manual operation, the number of rings pushed into the intermediate frequency furnace is often not accurately controlled, resulting in the problems of over-pushing or under-pushing, which leads to inconsistent heating times of the rings in the intermediate frequency furnace, and there are problems where some rings do not reach the required heating level, resulting in a large temperature difference between the rings; therefore, a structure that can achieve consistent heating time of the rings in the intermediate frequency furnace and maintain uniform temperature is designed. Summary of the Utility Model:

[0003] The purpose of the utility model is to address the deficiencies of the existing technology, and provide a quantitative pushing mechanism for an intermediate frequency furnace. The pushing mechanism can push a quantitative number of rings into the intermediate frequency furnace for heating, and accordingly, the same number of rings will be pushed out of the intermediate frequency furnace, thereby achieving consistent heating time of the rings in the intermediate frequency furnace, ensuring that the rings reach the required heating level, and thus realizing uniform temperature and uniform discharging speed of the rings.

Specific implementation manner:

[0021] Example: See Figures 1 to 4 As shown, a quantitative pushing mechanism of an intermediate frequency furnace includes a bottom plate 1. A longitudinal intermediate frequency furnace 2 is fixedly connected to the middle of the bottom plate 1. A furnace chamber 21 penetrating the front and rear end faces of the intermediate frequency furnace 2 is formed inside the intermediate frequency furnace 2. Two supporting rollers 3 are inserted into the lower part of the furnace chamber 21. The front and rear ends of the supporting rollers 3 respectively extend out of the intermediate frequency furnace 2 and are fixedly connected with a V-shaped feeding chute 4 and a discharging chute 5. Supporting legs 6 are fixedly connected to the rear end of the discharging chute 5 and the front end of the feeding chute 4 respectively. The supporting legs 6 are fixedly connected to the bottom plate 1. A quantitative feeding assembly 7 is arranged on the feeding chute 4;

[0022] The quantitative feeding assembly 7 includes a pushing plate 71 inserted into the front end of the feeding chute 4. A vertical connecting rod 72 is arranged on the front side of the pushing plate 71. A longitudinal guiding groove 41 is formed on the front side of the feeding chute 4. The connecting rod 72 is inserted into the guiding groove 41 of the feeding chute 4; A fastening bolt 73 is inserted into the upper end of the connecting rod 72, and the end of the fastening bolt 73 is screwed on the pushing plate 71; The lower end of the connecting rod 72 is located below the feeding chute 4 and is connected with the piston rod of a longitudinal pushing cylinder 74. The pushing cylinder 74 drives the pushing plate 71 to longitudinally move in the feeding chute 4; The pushing cylinder 74 is fixedly connected to an end seat 75, and the end seat 75 is fixedly connected to the bottom plate 1.

[0023] The supporting rollers 3 are round rollers. The two supporting rollers 3 are distributed on both sides of the middle of the feeding chute 4. The outer walls of the supporting rollers 3 are respectively tangent to the inner bottom surface of the feeding chute 4. The inner bottom surface of the feeding chute 4 and the inner bottom surface of the discharging chute 5 are flush. Thus, after the ferrule in the feeding chute 4 enters the furnace chamber 21, it can smoothly move on the supporting rollers 3, and at the same time, the ferrule on the supporting rollers 3 can smoothly move into the discharging chute 5.

[0024] An avoiding slot 61 opposite to the connecting rod 72 is formed on the supporting leg 6 on the front side of the feeding chute 4. The avoiding slot 61 facilitates the assembly and connection of each component of the quantitative feeding assembly 7.

[0025] A longitudinal guide rod 76 is fixedly connected to the lower end of the connecting rod 72. The guide rod 76 is inserted into the end seat 75. The piston rod of the pushing cylinder 74 is located below the guide rod 76. A vertical linkage plate 77 is fixedly connected to the front part of the guide rod 76 by insertion. The piston rod of the pushing cylinder 74 is connected to the linkage plate 77. This is the connection structure between the pushing cylinder 74 and the connecting rod 72. The guide rod 76 cooperating with the piston rod of the pushing cylinder 74 can limit the rotation of the connecting rod 72. At the same time, based on the guide rod 76 being arranged on the end seat 75, it can share the force generated by the self-weight of the pushing plate 71 and the connecting rod 72 for the piston rod of the pushing cylinder 74.

[0026] An adjusting bolt 78 facing the linkage plate 77 is screwed on the front end face of the end seat 75. By adjusting the position of the adjusting bolt 78, the distance between the linkage plate 77 and the adjusting bolt 78 can be controlled, and thus the displacement of the pushing plate 71 can be controlled.

[0027] A guide hole penetrating the front and rear end faces of the end seat 75 is formed on the end seat 75. The guide rod 76 is inserted into the guide hole of the end seat 75. The pushing cylinder 74 is fixedly connected to the rear end face of the end seat 75.

[0028] A jack is formed in the lower part of the linkage plate 77. There is a T-shaped connecting pin 79 in the jack. The rear end of the connecting pin 79 extends out of the linkage plate 77 and is screwed and fixed with a swivel joint 711. The piston rod of the pushing cylinder 74 is screwed and fixed on the swivel joint 711.

[0029] A spring 710 is inserted on the connecting pin 79 on the front side of the linkage plate 77. The rear end of the spring 710 abuts against the linkage plate 77, and the front end abuts against the head of the connecting pin 79. During specific operation, if the piston rod of the pushing cylinder 74 is fixedly connected to the linkage plate 77, there is a situation where the pushing cylinder 74 does not operate at full stroke. When the air pressure driving the pushing cylinder 74 is too large, the pulling force of the pushing cylinder 74 is too large, and the problem of deformation of the linkage plate 77 will occur. By setting the spring 710, an elastic connection between the piston rod of the pushing cylinder 74 and the linkage plate 77 is realized, which can not only meet the full-stroke operation of the pushing cylinder 74, but also not easily cause the problem of deformation of the linkage plate 77.

[0030] An avoidance hole opposite to the swivel joint 711 is formed on the end seat 75.

[0031] Working principle: This solution is a quantitative pushing mechanism for an intermediate frequency furnace. The quantitative pushing mechanism is mainly composed of a pushing plate 71, a connecting rod 72, and a pushing cylinder 74. The stroke of the pushing cylinder 74 can control the longitudinal movement of the pushing plate 71 in the feeding channel 4, and the longitudinal movement displacement is consistent. Thus, it can ensure that the number of rings pushed into the intermediate frequency furnace is quantitative, and indirectly control the heating time of the rings in the intermediate frequency furnace to be consistent.

[0032] The embodiments are used to illustrate the present utility model by way of example and are not intended to limit the present utility model. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present utility model. Therefore, the scope of the protection of the rights of the present utility model shall be as set forth in the claims of the present utility model.
