Description

Technical Field

[0001] This utility model belongs to the field of heat treatment furnace production equipment, specifically a heat treatment furnace material fork support rod. Background Technology

[0002] The heat treatment furnace fork support rod is mainly used for automated loading and unloading of sheet metal parts in heat treatment furnaces. Existing heat treatment furnaces require high-temperature processes during production, and loading and unloading are carried out using heat treatment furnace forks. Most heat treatment furnace fork support rods are made of steel pipes. During high-temperature use, the steel pipes are easily deformed due to temperature. In addition, the existing support rods have a large contact area with the product during use, which can easily lead to rapid temperature changes in the product and the formation of a large oxide layer, which is not conducive to the continuous use of the support rods. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat treatment furnace charge fork support rod to solve the problem of easy deformation of existing support rods during use.

[0004] To achieve the above objectives, this utility model employs the following technical solution: a heat treatment furnace charge fork support rod, comprising a support tube, with a first reinforcing tube and a second reinforcing tube respectively disposed on both sides of one end of the support tube. The support tube has a hollow structure, with an inner reinforcing tube fitted inside. A blocking plate is disposed on one end of the support tube opposite to the first reinforcing tube, and an air pipe connector mounting plate is disposed on one end of the support tube opposite to the blocking plate. An air inlet is provided between the air pipe connector mounting plate and the support tube. By configuring the support tube with a double cavity, air is blown into the inner cavity and exhausted from the outer cavity, thereby achieving the purpose of reducing temperature.

[0005] The preferred structure of this solution includes an air intake chamber located inside the support tube at the end opposite the air inlet.

[0006] The preferred structure of this solution also includes an exhaust chamber distributed circumferentially on the inner side of the support tube. The exhaust chamber is located between the inner reinforcing tube and the support tube. Gas is discharged from the end of the exhaust chamber through the exhaust chamber, thus carrying away heat.

[0007] As another preferred structure of this solution, a groove is provided on the support tube at the bottom of the first reinforcing tube, and the groove is circumferentially distributed on the support tube.

[0008] As another preferred structure of this scheme, an exhaust chamber support block is provided inside the inner reinforcing tube.

[0009] The beneficial effect of this utility model is that by setting the support rod as a double-layer cavity, air is blown into the inner cavity and air is exhausted from the outer cavity, thereby achieving the purpose of reducing the temperature. The specific implementation method is further described in the following embodiments. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] See Figures 1 to 3 The system includes a support tube, with a first reinforcing tube and a second reinforcing tube respectively arranged on both sides of one end. The support tube has a hollow structure, with an inner reinforcing tube fitted inside. A blocking plate is provided on the support tube opposite the first reinforcing tube at one end, and an air pipe connector mounting plate is provided on the support tube opposite the blocking plate at one end. An air inlet is provided between the air pipe connector mounting plate and the support tube. By setting the support tube into a double cavity, air is blown into the inner cavity and exhaust is discharged from the outer cavity to achieve the purpose of reducing temperature. An air inlet chamber is provided inside the support tube opposite the air inlet at one end, and exhaust chambers are arranged circumferentially on the inner side of the support tube. The exhaust chambers are located between the inner reinforcing tube and the support tube, and gas is discharged from the end of the exhaust chamber through the exhaust chambers to carry away heat. A groove is provided on the support tube at the bottom of the first reinforcing tube, and the grooves are arranged circumferentially on the support tube. An exhaust chamber support block is provided inside the inner reinforcing tube.

[0016] During implementation, cooling gas continuously enters from the air inlet and exits from the end of the exhaust chamber, thereby carrying away heat, blowing air into the inner cavity, and exhausting through the outer cavity to achieve the purpose of cooling. This can effectively reduce the deformation of the heat treatment furnace fork support tube, thereby improving the efficiency of use.
