Description

Technical Field

[0001] The invention relates to the technical field of heat treatment modification of profiles, and in particular to a modification device and method for wear-resistant and corrosion-resistant profiles. Background Art

[0002] The strength of many profiles (such as metal profiles) in their original state may not be sufficient to meet the needs of specific engineering applications. Their strength can be significantly improved through heat treatment. For some profile application scenarios that require wear resistance or corrosion resistance, improving hardness is one of the important purposes of heat treatment. For example, tool steel profiles are used to manufacture various tools such as knives and molds. Through quenching and low-temperature tempering treatment, tool steel can form a high-hardness martensitic structure. Like high-speed steel W18Cr4V, after quenching and tempering, the hardness can reach 63-66HRC (Rockwell hardness). This high-hardness profile can maintain the sharpness of the cutting edge during the cutting process, and can resist the wear and deformation of the workpiece material during the mold forming process, thereby extending the service life of the tool.

[0003] In the process of using a heat treatment furnace to modify the profile, as the profile material enters and exits the furnace body and the furnace door rises and falls, some external air will enter the interior of the furnace body. When the air enters the interior of the furnace body, the oxygen in it will react with the surface of the profile to produce an oxidation reaction. In a high-temperature heat treatment environment, this oxidation reaction is more intense. For example, for metal profiles, iron will react with oxygen to produce various iron oxides, such as ferrous oxide, ferric oxide and ferroferric oxide. The structure of these oxides is relatively loose, unlike some dense oxide films formed by special treatment that have a protective effect. The loose oxides are easy to fall off during friction, affecting the wear resistance of the modified profile. The loose oxides cannot effectively prevent the contact between the corrosive medium (such as water, acidic or alkaline solution) and the profile substrate. The corrosive medium can penetrate into the profile through the pores of the oxide, causing further corrosion reactions, affecting the corrosion resistance of the modified profile. For this reason, we propose a modification processing device and method for wear-resistant and corrosion-resistant profiles. Summary of the invention

[0017] A method for modifying a wear-resistant and corrosion-resistant profile comprises the following steps:

[0018] S1: During the process of heat treatment and modification of the profile using the heat treatment furnace, the furnace door is driven to move downward by the lifting assembly and the first guide assembly, and the heat treatment furnace is blocked and closed by the downward movement of the furnace door. During the downward movement of the furnace door, the lower end of the furnace door is abutted against the transmission pressure plate at the upper end of the fixed frame, and the unloading platform is pushed to move from the upper end of the bearing platform to the lower end of the bearing platform;

[0019] S2: After the furnace door descends to close the heat treatment furnace and pushes the discharge table to move, the profile to be modified is placed on the discharge table. After placement, the furnace door is driven to rise by the lifting assembly and the first guide assembly. During the process of the furnace door rising, the bottom of the furnace door is no longer against the transmission pressure plate. At this time, the discharge table carrying the material is reset by the elastic force of each group of springs on the connecting assembly;

[0020] S3: After the unloading table is reset, a sealed space is formed with the interior of the heat treatment furnace under the action of the mounting plate, the bearing platform and the accordion cover.

[0022] S5: After the heat treatment and modification of the profile is completed, the furnace door is raised through the cooperation of the lifting component and the first guide component, and in the process of the furnace door rising, the support platform is moved to the outside of the heat treatment furnace through the driving component and the second guide component. In the process of the furnace door rising and the support platform sliding outward, a sealed space is formed with the interior of the heat treatment furnace under the action of the mounting plate, the support platform and the accordion cover, and the oxygen in the space has been consumed, so that the profile material will not bring external air into the interior of the heat treatment furnace during the process of entering and exiting the heat treatment furnace, and further, during the heat treatment and modification of the profile, the surface of the profile will not undergo oxidation reaction due to air to form loose oxides, ensuring that the profile has good wear resistance and corrosion resistance after the heat treatment and modification.

After the furnace door 102 descends to close the heat treatment furnace 101 and pushes the discharge platform 702 to move, the profile to be modified is placed on the discharge platform 702. After the placement is completed, the furnace door 102 is driven to rise by the lifting assembly and the first guide assembly.

[0048] It should be noted that: each set of first sleeves 802 and first slide bars 803 facilitates the telescopic movement of the auxiliary material discharging platform 702, and each set of springs 804 facilitates the reset movement of the auxiliary material discharging platform 702 after the movement;

[0049] It is worth noting here that the spring 804 is a high-elasticity spring 804, which can effectively reset the unloading table 702 after auxiliary movement, and the spring 804, the third L-shaped frame 801, the first sleeve 802 and the first slide rod 803 are all made of high-temperature resistant materials.

During the downward movement of the furnace door 102, the lower end of the furnace door 102 is abutted against the transmission pressure plate 902 at the upper end of the fixed frame 901, pushing the unloading table 702 to move from the supporting platform 103 to the bottom of the supporting platform 103.

During the movement of the movable plate 302, the sliding guiding effect of the guide hole 401 and the guide rod 402 is used to make the movable plate 302 move toward or away from the heat treatment furnace 101 after being subjected to force. Through the movement of the movable plate 302, the support platform 103 is driven to move synchronously.

[0056] Preferably, a transparent observation window 204 for observing the processing status is provided on the mounting plate 202;

[0057] It should be noted here that the transparent observation window 204 facilitates observation and confirmation of the processing status of the profile material inside the carrier 103 .

[0058] A method for modifying a wear-resistant and corrosion-resistant profile comprises the following steps:

[0059] S1: During the heat treatment process of the profiles using the heat treatment furnace 101, the furnace door 102 is driven to move downward by the lifting assembly and the first guide assembly. The heat treatment furnace 101 is blocked and closed by the downward movement of the furnace door 102. During the downward movement of the furnace door 102, the lower end of the furnace door 102 is abutted against the driving pressure plate 902 at the upper end of the fixing frame 901, pushing the unloading platform 702 from the upper end of the carrier platform 103 to the lower end of the carrier platform 103 (see Figure 8 status);

[0060] S2: After the furnace door 102 descends to close the heat treatment furnace 101 and pushes the discharge table 702 to move, the profile to be modified is placed on the discharge table 702. After the placement is completed, the furnace door 102 is driven to rise by the lifting assembly and the first guide assembly. During the process of the furnace door 102 rising, the bottom of the furnace door 102 is no longer against the transmission pressure plate 902. At this time, the discharge table 702 carrying the material is reset by the elastic force of each group of springs 804 on the connecting assembly;

[0061] S3: After the unloading table 702 is reset, a sealed space is formed with the interior of the heat treatment furnace 101 under the action of the mounting plate 202, the carrying platform 103 and the accordion cover 203. At this time, the combustion type deaerator is started to burn and consume the air in the space;

[0063] S5: After the heat treatment and modification of the profile is completed, the furnace door 102 is raised through the cooperation of the lifting component and the first guide component, and in the process of the furnace door 102 rising, the support platform 103 is moved to the outside of the heat treatment furnace 101 through the driving component and the second guide component. In the process of the furnace door 102 rising and the support platform 103 sliding outward, under the action of the mounting plate 202, the support platform 103 and the accordion cover 203, a sealed space is formed with the interior of the heat treatment furnace 101, and the oxygen in the space has been consumed, so that when the profile material enters and exits the heat treatment furnace 101, the external air will not be brought into the interior of the heat treatment furnace 101, and further, during the heat treatment and modification of the profile, the surface of the profile will not undergo oxidation reaction due to air to form loose oxides, thereby ensuring that the profile has good wear resistance and corrosion resistance after the heat treatment and modification.

10. A method for modifying a wear-resistant and corrosion-resistant profile, which is based on the modification processing device for a wear-resistant and corrosion-resistant profile as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1: During the process of heat treatment modification processing of the profile using the heat treatment furnace (101), the furnace door (102) is driven to move downward by the lifting assembly and the first guide assembly, and the heat treatment furnace (101) is blocked and closed by the downward movement of the furnace door (102). During the downward movement of the furnace door (102), the lower end of the furnace door (102) is abutted against the transmission pressure plate (902) at the upper end of the fixed frame (901), so as to push the unloading platform (702) to move from the upper part of the bearing platform (103) to the lower part of the bearing platform (103); S2: After the furnace door (102) descends to close the heat treatment furnace (101) and pushes the discharge platform (702) to move, the profile to be modified is placed on the discharge platform (702). After the placement is completed, the furnace door (102) is driven to rise by the lifting component and the first guide component. During the process of the furnace door (102) rising, the bottom of the furnace door (102) no longer abuts against the transmission pressure plate (902). At this time, the discharge platform (702) carrying the material is reset by the elastic force of each group of springs (804) on the connecting component; S3: After the unloading table (702) is reset, a sealed space is formed with the interior of the heat treatment furnace (101) under the action of the mounting plate (202), the bearing platform (103) and the accordion cover (203). At this time, the combustion type deaerator is started to burn and consume the air in the space; S4: After the air treatment is completed, the driving assembly and the second guide assembly interact with each other to drive the support platform (103) to move toward the inside of the heat treatment furnace (101), so that the profile placed on the discharge platform (702) is located inside the heat treatment furnace (101). After the movement of the support platform (103) is completed, the lifting assembly and the first guide assembly cooperate with each other to drive the furnace door (102) to descend and block the heat treatment furnace (101), thereby assisting the heat treatment furnace (101) to perform stable heat treatment modification processing on the profile; S5: After the heat treatment and modification of the profile is completed, the furnace door (102) is raised by the cooperation between the lifting component and the first guide component, and during the process of the furnace door (102) rising, the support platform (103) is moved to the outside of the heat treatment furnace (101) through the driving component and the second guide component. During the process of the furnace door (102) rising and the support platform (103) sliding outward, a sealed space is formed with the interior of the heat treatment furnace (101) under the action of the mounting plate (202), the support platform (103) and the accordion cover (203), and the oxygen in the space has been consumed, so that when the profile material enters and exits the heat treatment furnace (101), the external air will not be brought into the interior of the heat treatment furnace (101), and further, during the heat treatment and modification of the profile, the surface of the profile will not undergo oxidation reaction due to air to form loose oxides, thereby ensuring that the profile has good wear resistance and corrosion resistance after the heat treatment and modification.
