Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to the continuous heating furnace for the bar shown in the attached drawings 1-5, the heating furnace 1 is provided with a support 11 and a heating furnace body 12 arranged on the support 11, a feeding port 12a and a discharging port 12b are sequentially arranged on two sides of the heating furnace body 12, and a heating cavity 12c used for placing and continuously heating a plurality of bars (shown as 100 in the drawing) is communicated between the feeding port 12a and the discharging port 12 b. A plurality of bars are continuously placed into a heating cavity 12c of the heating furnace body 12 through the feeding hole 12a, the bars placed in the heating cavity 12c are continuously heated through the heating cavity 12c, the bars to be heated can be continuously placed at the feeding hole 12a, and the continuous heating operation of the heating furnace is realized.

In order to facilitate the continuous feeding of the rods to be heated at the feeding port 12a, a plurality of rods in the heating cavity 12c need to be continuously fed out through the discharging port 12 b. Therefore, a conveying device connected with the discharge port 12b is arranged outside the side of the heating furnace body 12 positioned at the discharge port 12 b. Preferably, the conveying device is a conveying roller 4 arranged at intervals along the length direction of the bar, and continuously outputs the bar in the heating cavity 12 c. And preferably, a baffle 5 is arranged outside the conveying roller 4 to prevent the bar from falling.

In order to realize the continuous heating of the heating cavity 12c, the support 11 has a top inclined plane 11a, the heating furnace body 12 is arranged on the top inclined plane 11a, the feeding hole 12a is positioned at the higher side of the heating furnace body 12, the discharging hole 12b is positioned at the lower side, and the inner bottom surface of the heating cavity 12c is parallel to the top inclined plane 11 a. The heating furnace body 12 is in an inclined state as a whole through the top inclined plane 11a at the top of the bracket 11, and the inner bottom surface of the heating cavity 12c is ensured to be in an inclined state under the limitation that the inner bottom surface of the heating cavity 12c is parallel to the top inclined plane 11 a. Consequently, in the heating chamber 12c is put into with the rod in succession through the feed inlet 12a of higher position, the gravity through rod self along heating chamber 12c in the bottom surface towards discharge gate 12b direction slow roll heating to continue roll and carry on conveying on the delivery roller, so that the rod can be put into in succession in heating chamber 12c and heat, the efficiency problem of adopting the unified heating of heating furnace has been solved, and delivery roller 4 has reduced the follow-up processing cycle of taking out the rod after will heating and carrying out next process processing simultaneously.

When the rod material is placed through the feed port 12a, there is an inclined state in which both ends of the rod material are not in the same horizontal plane, so that one end is high and the other end is low. When the bar is placed in the heating cavity 12c in this state, after the bar rolls along the inclined plane of the heating cavity 12c, one end of the bar contacts with the side wall of the heating furnace body 12, and the other end of the bar contacts with the surface of the bar at the bottom (as shown in fig. 2), the bar rolls and impacts the side wall of the heating furnace body 12 and the surface of the bar at the bottom under the action of the rolling inertia of the bar, thereby causing damage. Therefore, in order to solve this problem, a deviation correcting mechanism for the rod is provided on the side wall of the heating cavity 12c on the side of the feeding hole 12 a.

Specifically, the mechanism of rectifying includes that the board 2 of rectifying that sets up along this side wall face direction correspondence on the heating chamber 12c both sides lateral wall, the board 2 of rectifying is located feed inlet 12a one end articulates on the heating chamber 12c lateral wall, be equipped with elastomeric element (preferably spring 3) between the board 2 middle part position of rectifying and this lateral wall. When the bar is placed in the heating cavity 12c to be in an inclined state, the lower end of the bar contacts the deviation correcting plate 2 on the side and extrudes the deviation correcting plate 2 under the action of gravity, and the deviation correcting plate 2 is tightly attached to the end of the bar side under the action of the elastic force of the spring 3 to block the state that the bar side slides downwards along the inner bottom surface of the heating cavity 12c and limit the bar to continuously slide or reduce the sliding speed. Under the action, the higher other end of the bar is in contact with the deviation-correcting plate 2 on the same side (as shown in fig. 4), and the deviation-correcting plate 2 does not block the end, so that the end can roll downwards at a higher rolling speed until the end is flush with the lower end of the bar after contacting the deviation-correcting plate 2, the inclined bar is corrected to a horizontal position (as shown in fig. 5), and the bar slides downwards under the action of the inclined inner bottom surface of the heating cavity 12c and the gravity of the bar to separate from the blocking action of the deviation-correcting plates on the two sides, so that the problem of surface contact between the bar and the side wall of the heating cavity 12c and the bar on the bottom is solved, and the problem of damage caused by the two impacts is avoided.

In order to facilitate the bar to break away from the blocking effect of the deviation rectifying plate after the deviation rectification is carried out through the deviation rectifying plate 2, the whole deviation rectifying plate 2 is of an arc-shaped structure. This arc structure remains throughout to have less contact point with the rod tip for can break away from the board 2 of rectifying smoothly after the rod rectifies, prevent the rod through the problem of rectifying board 2 jamming.

The principle of the utility model is that: the inclined heating cavity of the heating furnace can continuously heat a plurality of bars, so that the problem that the heating furnace is not enough or too long to heat the whole body is avoided, and the problem of the whole process efficiency caused by the fact that the heating furnace needs to discharge materials and unload materials in a unified manner is solved. And the deviation correcting mechanism arranged in the heating cavity ensures that the bars have a stable rolling state when being continuously heated, and avoids the problem that the bars are damaged in the heating cavity and adjacent bars due to the inclination of the bars.
