Technical Field

[0001] This utility model relates to the field of billet heating technology, and more specifically, to a furnace door sealing frame for a billet heating furnace. Background Technology

[0002] After heating steel billets, steel mills can forge them into thin plates. The commonly used heating equipment is a heating furnace. Existing furnace doors include traditional swing doors and doors that are opened and closed by pulling up and down with steel cables. Although swing doors have strong sealing, they have a large opening range and are cumbersome to operate. Doors that are opened by pulling up and down with steel cables are convenient to open, but their sealing is poor. Furthermore, the closing angle of the former two types cannot be adjusted, so when the sealing components are damaged, the sealing angle cannot be compensated in time. Utility Model Content

The furnace door is used to seal the outlet of the mold. Anchor points and connecting rods are used to connect the heating furnace and the furnace door. The furnace door moves along the swing direction of the connecting rod and presses the furnace door against the outlet under its own weight. The adjustment mechanism is used to adjust the vertical position of the anchor point, thereby indirectly adjusting the closing angle of the furnace door.

[0005] Furthermore, it includes a C-shaped frame installed on the upper part of the heating furnace, with hinge blocks 1 installed at the four corners of the side wall of the C-shaped frame, and a hinge block 2 corresponding to the hinge block 1 at the upper end of the furnace door. The two ends of the connecting rod connect the hinge block 1 and the hinge block 2. The hinge block 1, the hinge block 2 and the connecting rod on the same side form a parallelogram, and the furnace door remains vertical when it moves.

[0006] Furthermore, the frame is a split type, consisting of uprights and crossbeams. The adjustment mechanism includes a rectangular groove on the upper end of the uprights, a rectangular column installed on the crossbeam, the rectangular column being inserted into the rectangular groove, a threaded groove at the center of the rectangular column, a threaded column inside the threaded groove, the lower end of the threaded column pressing against the rectangular groove, and an electric drive mechanism installed at the upper end of the threaded column, which drives the threaded column to rotate.

[0007] Furthermore, the lifting mechanism is a winch, with guide wheels installed at the upper end of the U-shaped frame, and a connecting rope is installed between the pulling end of the winch and the furnace door, with the connecting rope passing around the guide wheels.

[0008] Furthermore, the side wall of the furnace door is provided with an incision groove, and the incision groove is provided with insulation cotton protrusions.

[0009] The beneficial effects of this utility model are: through the action of the upper and lower anchor points and connecting rods, the furnace door has good sealing performance while also being easy to open; through the action of the adjustment mechanism, the closing angle of the furnace door can be adjusted, and when the sealing component is damaged, the sealing angle can be compensated to achieve sealing.

[0011] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0012] This application provides a furnace door sealing frame for a billet heating furnace. Please refer to [reference needed]. Figures 1-4 It includes a heating furnace 1, a workpiece body 2, a lifting mechanism 3, and a billet outlet 4, and also includes... Furnace door 5 is used to seal the outlet 4; Anchor point 6 and connecting rod 7 are used to connect heating furnace 1 and furnace door 5. Furnace door 5 moves along the swing direction of connecting rod 7 and presses the blank outlet 4 under its own weight. The adjustment mechanism 8 is used to adjust the position of the anchor point 6 in the vertical direction, and indirectly adjust the closing angle of the furnace door 5.

[0013] In practical applications, the retraction of the hoisting mechanism 3 can drive the furnace door 5 to move obliquely upward. With two layers of anchor points 6 and connecting rods 7, the line connecting the anchor points 6 and connecting rods 7 forms a parallelogram, which allows the furnace door 5 to close and open the outlet 4. Under the action of the furnace door 5's own weight, the furnace door 5 can tightly press the outlet 4 to achieve a sealing effect. like Figure 1As shown, at this time, a regular quadrilateral can be formed between the upper and lower anchor points 6 and the connecting rod 7. Through the action of the adjustment mechanism 8, the upper anchor point 6 can be moved upward by a certain distance, and an approximately regular quadrilateral shape is formed between the upper and lower anchor points 6 and the connecting rod 7. The angle of the furnace door 5 is tilted to the left, so as to achieve the purpose of adjusting the angle of the furnace door 5.

[0014] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The furnace includes a U-shaped frame 11 installed on the upper part of the heating furnace 1. Hinges 12 are installed at the four corners of the side wall of the U-shaped frame 11. Hinges 2 13 corresponding to Hinges 12 are provided on the upper part of the furnace door 5. The two ends of the connecting rod 7 are connected to Hinges 12 and Hinges 2 13. Hinges 12, Hinges 2 13 and connecting rod 7 on the same side form a parallelogram. The furnace door 5 remains vertical when it moves.

[0015] In practical applications, the C-shaped frame 11 supports the hinge block 12. The furnace door 5 can rotate stably by connecting the hinge block 12 and the two sets of hinge blocks 13.

[0016] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The frame 11 is a split type, consisting of a column 111 and a crossbeam 112. The adjustment mechanism 8 includes a rectangular groove 1111 on the upper end of the column 111. A rectangular column 1121 is installed on the crossbeam 112. The rectangular column 1121 is inserted into the rectangular groove 1111. A threaded groove 1122 is opened at the center of the rectangular column 1121. A threaded column 1123 is provided in the threaded groove 1122. The lower end of the threaded column 1123 abuts against the rectangular groove 1111. An electric drive mechanism 1124 is installed on the upper end of the threaded column 1123. The electric drive mechanism 1124 drives the threaded column 1123 to rotate.

[0017] In practical applications, the rectangular frame 11 is designed as a split type. The rotation of the electric drive mechanism 1124 drives the threaded column 1123 to rotate. Through the meshing action of the threaded groove 1122, the threaded column 1123 gradually protrudes downward from the threaded groove 1122. Under the reaction action, the rectangular column 1121 and the crossbeam 112 rise upward, eventually driving the hinge block 12 to move upward, thereby achieving the purpose of adjusting the height of the hinge point.

[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The lifting mechanism 3 is a winch 31. A guide wheel 32 is installed on the upper end of the frame 11. A connecting rope 33 is installed between the pulling end of the winch 31 and the furnace door 5. The connecting rope 33 passes around the guide wheel 32.

[0019] In practical applications, the guide wheel 32 facilitates the transmission of tension from the connecting rope 33 to the furnace door 5.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The side wall of the furnace door 5 is provided with an incision groove 51, and the incision groove 51 is provided with insulation cotton protrusions 52.

[0021] In practical applications, the protrusions of the insulation cotton 52 can increase the sealing between the furnace door 5 and the outlet 4.
