Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a feeding structure of a heating furnace. Background Art

[0002] High-frequency electromagnetic induction heating furnaces are currently the most efficient and fastest induction heating equipment for heating metal materials, offering low energy consumption, energy conservation, and environmental protection. Their operating principle is as follows: a high-frequency, high-current flows through a heating coil wound into a ring or other shape, generating a strong magnetic flux with instantaneous polarity changes within the coil. When a heated object, such as a metal, is placed within the coil, the magnetic flux penetrates the entire object, generating a correspondingly large eddy current within the object in the opposite direction of the heating current. Due to the resistance within the heated object, a significant amount of Joule heat is generated, rapidly raising the object's temperature and achieving the desired effect of heating all metal materials.

[0003] In order to facilitate the workpiece to enter the heating furnace, transmission rollers are set on both sides of the heating furnace. The driving force of the transmission rollers is used to bring the workpiece into the heating furnace. However, during the workpiece transportation process, the workpiece may deviate, which will eventually cause the workpiece to collide with the heating furnace, causing the workpiece to fall. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the deficiencies in the prior art, the present invention provides a heating furnace feeding structure, which has the advantage that the workpiece will not be shifted during transmission, thus solving the above-mentioned problems.

[0006] 2) Technical solution

[0007] The cam is fixedly mounted on the top of the loading platform, and the cam is mounted on the bottom of the loading platform, the cam being arranged on a circle with a center of rotation of the rotating shaft so as to prevent the loading of the cam from being displaced during the loading of the cam.

[0008] Preferably, a baffle is fixedly mounted on the tail end of the extension rod, a circular groove corresponding to the roller assembly is formed at the bottom of the baffle, and inclined plates are fixedly mounted on both sides of the baffle.

[0009] Preferably, there are two baffles, which are symmetrically arranged on both sides of the workpiece.

[0010] Preferably, the extension rod is detachably connected to the sliding sleeve via a threaded sleeve, a screw and a hand wheel.

[0011] Preferably, a through hole corresponding to the electric push rod is opened inside the bracket, and the electric push rod is installed in the through hole.

[0012] Preferably, the extension rod is slidably connected to the sliding sleeve via a limiting bar and a limiting groove.

[0013] Preferably, the sliding sleeve is slidably connected in the vertical frame through a slider and a vertical groove.

[0014] 3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a heating furnace feeding structure with the following beneficial effects:

[0016] 1. The feeding structure of the heating furnace has two baffles straddling the outside of the roller group. There are guiding inclined plates at both ends of the baffles. When the workpiece is transmitted by the roller group, the workpiece will always be between the two baffles, thereby ensuring that the workpiece will not shift during the transmission process.

[0017] 2. The feeding structure of the heating furnace pushes the sliding sleeve up or down in the bracket through the output end of the electric push rod, and then the extension rod can be moved up or down, thereby adjusting the horizontal height of the baffle, which is convenient for adapting to the height of the workpiece; the screw can be driven to relax through the handwheel, and the screw no longer presses on the extension rod, and then the extension rod can move forward or backward in the sliding sleeve, thereby adjusting the front and rear position of the baffle, which is convenient for adapting to the width of the workpiece.

[0027] See also Figure 2-4The bottom of the sliding sleeve 25 is fixedly connected to the output end of the electric push rod 211. A through hole corresponding to the electric push rod 211 is opened inside the bracket 21. The electric push rod 211 is installed in the through hole.
