Description

Technical Field

[0001] The utility model relates to the technical field of forging normalizing furnaces, in particular to a forging normalizing furnace with uniform heating. Background Art

[0002] Normalizing furnace is an important process to improve the toughness of steel parts. Its characteristic is to heat the steel plate to a temperature above the upper critical point of the ferrite-austenite phase transformation to make the steel austenitized, and after heat preservation and homogenization, it is cooled in the free atmosphere to make it disperse and precipitate at low temperature, thereby improving the strength of the steel and maintaining the toughness of the steel. From the perspective of composition design, under the condition of ensuring the same mechanical properties, the carbon or alloy element content in the steel can be reduced, thereby improving the weldability of the steel.

[0003] For example, the utility model with application number CN202321765276.X relates to the technical field of normalizing furnaces. The utility model has the advantage of being able to balance the pressure inside the furnace body, thus avoiding the trouble of opening the furnace door when the staff takes out the steel parts that have been heated inside the furnace body due to the difference in pressure inside and outside the furnace body; however, the existing normalizing furnaces usually heat on one side, which can easily lead to uneven heating of the forgings, which can easily cause the forgings to crack and be damaged, and the uneven heating can also lead to a long heating time, thereby affecting the quality of the forgings and the forging efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a uniformly heated forging normalizing furnace is provided. Utility Model Content

[0007] Furthermore, the mounting plates and the heat spreader components are distributed in an equidistant annular pattern about the center point of the furnace body, and there are four groups of heat spreader components.

[0008] Furthermore, a furnace door is provided on the left side of the front end of the furnace body, a base is provided at the lower end of the outside of the furnace body, and an exhaust box is provided on the rear side of the furnace body.

[0009] Furthermore, a mounting rod is provided inside the mounting hole, and an end portion of the mounting rod is connected to a connecting plate.

[0010] Furthermore, the end of the connecting plate is connected to a normalizing rack, and a supporting plate is installed on the inner side of the normalizing rack.

[0011] Furthermore, the sides of the normalizing rack are provided with reinforcement components for increasing the installation firmness, and the number of the reinforcement components is set to four.

[0012] Furthermore, the reinforcement assembly includes a vertical plate and a rotation adjustment rod, and the rotation adjustment rod is installed on the inner side of the vertical plate.

[0013] Furthermore, the reinforcement assembly further includes a connecting rod and a reinforcement frame. The connecting rod is installed on the surface of the rotation adjustment rod, and the end of the connecting rod is connected to the reinforcement frame.

[0014] The utility model provides a uniformly heated forging normalizing furnace, which has the following beneficial effects:

[0015] 1. The utility model uses four groups of heat-averaging components distributed in a ring on the inner wall of the furnace body to heat the workpiece on the outside of the workpiece at the same time through four sides to perform normalizing treatment on the workpiece, so that the workpiece is heated on all sides at the same time, increasing the heating uniformity and the normalizing efficiency of the workpiece. The mounting frame is used for installing the heating plate, and the blast port outputs gas through the blower in the blast box, so that the heat generated by the heating plate is more evenly distributed in the furnace body.

A mounting plate 2 is installed on the inner wall of the furnace body 1. The mounting plate 2 and the mounting hole 4 are used for inserting the mounting rod 7, and the mounting hole 4 is opened on the surface of the mounting plate 2. A furnace door 5 is provided on the left side of the front end of the furnace body 1, and a base 6 is provided at the lower end of the outside of the furnace body 1. A mounting rod 7 is provided inside the mounting hole 4. The four mounting rods 7 enable the normalizing rack 9 and the workpiece to be installed in the center of the furnace body 1. While the installation is stable, the workpiece is better heated all around. The end of the mounting rod 7 is connected to the connecting plate 8, the end of the connecting plate 8 is connected to the normalizing rack 9, and a support plate 10 is installed on the inner side of the normalizing rack 9.

[0023] like Figure 2 As shown, a heat-saturating assembly 3 for heating multiple surfaces simultaneously is arranged inside the mounting hole 4. Four groups of heat-saturating assemblies 3 are distributed in an annular manner on the inner wall of the furnace body 1. At the outside of the workpiece, heat is transported to the workpiece from all four sides for normalizing, so that the workpiece is heated all around at the same time to increase the heating uniformity and the normalizing efficiency of the workpiece. The heat-saturating assembly 3 includes a mounting frame 301, a heating plate 302, an air blast port 303 and an air blast box 304. A heating plate 302 is installed on the inner side of the mounting frame 301. The frame 301 is used for installing the heating plate 302, and a blast port 303 is provided on the side of the heating plate 302. The outer side of the blast port 303 is connected to a blast box 304. The blast port 303 outputs gas through the blower in the blast box 304, so that the heat generated by the heating plate 302 is more evenly distributed in the furnace body 1. The mounting plate 2 and the heat-saturating component 3 are distributed in equidistant annular spaces about the center point of the furnace body 1, and the number of heat-saturating components 3 is set to four. An exhaust box 12 is provided on the rear side of the furnace body 1.

[0024] like Figure 3As shown, the side of the normalizing rack 9 is provided with a reinforcement component 11 for increasing the installation firmness, and the number of the reinforcement components 11 is provided in four groups, the reinforcement component 11 includes a vertical plate 1101 and a rotation adjustment rod 1102, and the inner side of the vertical plate 1101 is installed with a rotation adjustment rod 1102, and the rotation adjustment rod 1102 drives the rotation of the connecting rod 1103 and the reinforcement frame 1104 after the rotation of the rotation adjustment rod 1102, so that after the installation rod 7 is inserted into the installation plate 2, the reinforcement component 11 also includes a connecting rod 1103 and a reinforcement frame 1104, the surface of the rotation adjustment rod 1102 is installed with a connecting rod 1103, and the end of the connecting rod 1103 is connected to the reinforcement frame 1104, and the reinforcement frame 1104 is rotatably buckled on the outside of the installation rod 7 to increase the stability of the normalizing rack 9.

[0025] In summary, the uniformly heated forging normalizing furnace is first based on Figure 1-Figure 3 7, and the workpiece is placed on the support plate 10 on the normalizing rack 9. The normalizing rack 9 is then inserted into the mounting hole 4 in the mounting plate 2 through the mounting rod 7. The four mounting rods 7 enable the normalizing rack 9 and the workpiece to be installed in the center of the furnace body 1. The installation is stable and the workpiece is better heated all around. Then, the adjusting rod 1102 is rotated to drive the rotation of the connecting rod 1103 and the reinforcement rack 1104, so that the reinforcement rack 1104 is rotated and buckled on the outside of the mounting rod 7, thereby increasing the stability of the normalizing rack 9. After installation, the furnace door 5 is closed, the heating plate 302 is energized to heat up, and the blast port 303 outputs gas through the blower in the blast box 304, so that the heat generated by the heating plate 302 is more evenly distributed in the furnace body 1. At this time, the four groups of heat-saturating components 3 are distributed in an annular manner on the inner wall of the furnace body 1. At the same time, heat is transported to the workpiece on all sides for normalizing, so that the workpiece is heated all around at the same time, increasing the heating uniformity and also increasing the normalizing efficiency of the workpiece.
