Description

Technical Field

[0001] The present invention relates to the technical field of mold surface treatment, and specifically to mold surface treatment equipment. Background Art

[0002] The mold material used for hammer forging dies has an overall hardness of the alloy material between HV380° and 420°, which is not easily broken in the best condition. During the forging process of steel hot forging products, after the raw material is heated to 1180°C to 1250°C and put into the initial blank for forging, in order to prevent the residual oxide film on the product surface, after sandblasting, there are defective depressions on the product surface. It is necessary to first use an air gun to remove the oxide film and then put it into the forming precision forging. During the process, the surface temperature of the material drops by 50°C to 80°C due to blowing, which reduces the material fluidity, increases the frictional resistance of the forming precision forging die cavity, and causes the mold to wear too fast and its life to decline. Therefore, a surface treatment equipment can be used to treat the mold surface, so that the surface hardness HV of the mold is increased to 588° - 620°, effectively improving the life. During the surface treatment work, a nitriding process will be used. In order to prevent personnel from being injured during operation, a convenient adjustment structure for the furnace body is provided to achieve the purpose of simple operation. Summary of the Invention

[0003] The purpose of the present invention is to provide mold surface treatment equipment to solve the problem of furnace body adjustment proposed in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: Mold surface treatment equipment, including a platform main body, a mold placement plate is installed at the top of the platform main body, a circulation hole is opened inside the mold placement plate, a limiting column is provided on the outer side wall of the circulation hole, a furnace body is covered outside the outer side wall of the mold placement plate, an adjustment structure is provided on the outer side wall of the furnace body, the adjustment structure includes a hoist main body, the hoist main body is arranged at both ends of the furnace body, a roller housing is fixed at the bottom end of the hoist main body, a roller main body is arranged inside the roller housing, a track main body is arranged at the bottom end of the roller main body, the track main body is installed at both ends of the platform main body, a lifting plate is connected at the lifting position inside the hoist main body, and hanging ear plates are welded at both ends of the outer wall of the furnace body.

[0005] Preferably, a rolling connection is formed between the track main body and the roller main body, and a welded integrated structure is formed between the hanging ear plate and the inside of the outer side wall of the furnace body.

[0006] Preferably, the hanging ear plates are symmetrically distributed about the vertical central axis of the furnace body, and the hoist main bodies are symmetrically distributed about their central axes at both ends of the furnace body.

[0007] Preferably, a welded integrated structure is formed between the bottom end of the hoist main body and the top end of the roller housing, and a motor is equipped at one end of one roller main body.

[0008] Preferably, a cooling system is provided inside the platform body. The limit posts are distributed in a ring about the center of the mold placement plate, and the outer diameter of the mold placement plate is smaller than the inner diameter of the bottom end of the furnace body.

[0009] Preferably, a hoisting machine body is installed on one side of the top end of the platform body. At the bottom end of the lifting arm on one side of the hoisting machine body, a housing body is installed. Inside the housing body, a winding wheel is installed, and a lifting rope is wound around the outer side wall of the winding wheel.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: This mold surface treatment equipment not only improves the furnace body adjustment ability of this mold surface treatment equipment, but also simultaneously improves the lifting ability and mold placement ability of this mold surface treatment equipment;

[0011] (1) By first installing the lifting machine body and welding the bottom end of the lifting machine body to the top end of the roller housing. Since the lifting machine body is equipped with main and auxiliary cylinders and other components for lifting, it can drive the lifting plate to move up and down during lifting. Until the lifting plate touches the bottom end of the hanging ear plate, it drives the furnace body to lift or lower. And one end of the roller body is equipped with a motor and a gearbox. When the motor is turned on, it drives the roller body to roll at the position of the track body, achieving the effect of horizontal movement of the furnace body. The overall work is relatively convenient, achieving the effect of adjusting the position of the furnace body, facilitating the placement and surface treatment of the mold;

[0012] (2) By installing the hoisting machine body on one side of the platform body, then installing a winding wheel inside the housing body, and equipping one end of the winding wheel with a motor for winding and unwinding the lifting rope after the winding wheel rotates. And the bottom end of the lifting rope can hang a hook for lifting the mold. After lifting, it is placed on the platform body, facilitating the loading and unloading of the mold, preventing problems such as accidental damage to the mold when the staff directly contacts the mold, and also providing a certain degree of convenience. And there are safety devices around the platform body, including a standing platform and a guardrail, etc., to ensure the safety of the staff;

[0013] (3) By fixing the mold placement plate on the top end of the platform body, opening a circulation hole for circulation. After the mold is lifted and placed on the mold placement plate, it is limited by the limit posts, and then the furnace body is covered outside the mold placement plate. Because there is a certain height between the mold placement plate and the platform body, it is convenient for subsequent nitriding work. After passing nitrogen, through a specially designed cooling circulation pipeline, the gas in the furnace body is pumped into the cooling system, and after cooling, the gas is injected into the furnace body through the return pipeline of the cooling system to quickly cool down, solving the traditional nitriding process, reducing the depth of the white bright layer on the surface, reducing the vein-like structure, improving wear resistance, overcoming the problems of bubbles, sand holes, and brittle cracks in the multiple welding repairs of used molds, and also facilitating multiple nitriding treatments to improve the mold life.
