Description

Technical Field

[0001] This utility model belongs to the field of heat treatment technology for parts, and in particular relates to a heat treatment device for the surface of parts. Background Technology

[0002] Heat treatment of parts refers to the process of heating, holding, and cooling parts in a solid state to obtain the desired microstructure and properties. This process mainly improves the mechanical, physical, and chemical properties of parts by changing their internal microstructure. Through surface heat treatment, parts heat treatment can obtain a high-hardness surface layer and favorable internal stress distribution, thereby improving the wear resistance and fatigue resistance of the workpiece. The main functions of parts heat treatment include improving mechanical properties, increasing wear and corrosion resistance, and improving machinability. However, existing parts heat treatment equipment cannot be set for a specific time and requires personnel to observe the process. Therefore, a surface heat treatment device for parts is proposed.

[0003] For example, Chinese patent CN215517527U discloses a surface heat treatment device for parts. It includes a base, a fixed support plate, a movable plate, a partition plate, and a motor; a heating coil is provided above the base, and a rotating shaft is located at the center of the base; a first through hole is provided below the fixed support plate, which engages with the rotating shaft; a positioning hole is provided above the fixed support plate; a positioning post is provided below the movable plate, which engages with the positioning hole; multiple protrusions are evenly distributed above the movable plate; and a detachable column is located at the center of the movable plate.

[0004] The aforementioned patent has the following problems:

[0005] Compared to existing heat treatment technologies, which cannot be timed and require manual monitoring during the process, increasing workload and hindering subsequent processing, we propose a surface heat treatment device for parts. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a heat treatment device for the surface of parts, which allows for setting the time during heat treatment and timely cooling after heat treatment.

[0007] In view of this, the present invention provides a surface heat treatment device for parts, including a processing box, and further comprising: a placement frame movably installed inside the processing box, a heating tube fixedly installed inside the placement frame, a placement plate fixedly installed at the bottom of the heating tube, a support block movably installed at the bottom of the placement frame, a cooling box fixedly installed on one side of the processing box, an end cover movably installed on the top of the cooling box, a cooler fixedly installed at the bottom of the end cover, a motor fixedly installed on the other side of the cooling box, and a wire mesh movably installed inside the cooling box.

[0008] Based on the above structure, the support block allows the placement frame to be placed inside the processing box, which in turn secures the heating tube. The placement plate then holds the parts requiring heat treatment. The heating time is set via a timer on top of the protective door. This allows for timed heat treatment without operator supervision, automatically stopping the heating process and reducing workload. The cooling box collects the parts. The end cover is opened, the heat-treated parts are placed on top of the wire mesh, and the end cover is closed. The refrigeration unit is activated to cool the air inside the cooling box, and the motor drives the fan to rotate, accelerating airflow and improving cooling efficiency. This combination ensures timely cooling after heat treatment, preventing delays in subsequent processing and increasing overall efficiency.

[0009] Preferably, a protective door is movably installed on the surface of the processing box, and a handle is fixedly installed on the surface of the protective door, which seals the processing box.

[0010] Preferably, the top of each placement frame is provided with heat dissipation holes, a filter screen is movably installed on the top of the heat dissipation holes, and a cover is movably installed on the top of the filter screen, so that the heat dissipation holes can easily dissipate heat.

[0011] Preferably, an insulation box is fixedly installed on one side of the end cap, and the inside of the insulation box is fixedly provided with a slot, and a drawer is movably installed inside the slot, so that the insulation box can conveniently keep the heat-treated parts warm.

[0012] Preferably, a ventilation pipe is provided through the other side of the cooling box, and a sealing plug is movably installed inside the ventilation pipe, so that the ventilation pipe can facilitate the replacement of air in the cooling box.

[0013] Preferably, the bottom of the insulated box is fixedly installed with a base plate, and a support plate is fixedly installed at the bottom of each base plate. A reinforcing plate is fixedly installed between the support plates, and the base plate facilitates support for operation.

[0014] Preferably, limiting plates are movably installed on both sides of the top of the base plate, and fixing bolts are installed through the inside of the limiting plates, which facilitates the positioning of the processing box and the insulation box.

[0015] The beneficial effects of this utility model are:

[0016] 1. This surface heat treatment device for parts can use support blocks to place the placement frame inside the processing box, then use the placement frame to fix the heating tube, and then use the placement plate to place the parts that need to be heat treated. The heating time of the heating tube can be set by the time controller on the top of the protective door. When used in conjunction with this device, the time can be set during heat treatment, and the heating work can be automatically stopped without the need for staff to observe, thus reducing the workload.

[0017] 2. This surface heat treatment device can collect parts using a cooling box. After opening the end cover, the heat-treated parts are placed on top of the wire mesh. Then, the end cover is closed, and the refrigeration unit is started to cool the air inside the cooling box. The motor is then started to drive the fan to rotate, which can accelerate air circulation and improve cooling efficiency. When used together, the parts can be cooled in time after heat treatment without delaying the next step of the work, thus increasing processing efficiency. Attached Figure Description
