Description

Technical Field

[0001] The invention relates to the technical field of heat treatment equipment, in particular to a processing furnace for die quenching heat treatment. Background Art

[0002] A heat treatment furnace, also known as a heat treatment furnace, is a device used to heat treat metals. This type of furnace is mainly used to improve the hardness, wear resistance and mechanical properties of metals to adapt to high temperature, high pressure or high wear working environments. At present, a heat treatment furnace is needed to heat the die (also called a mold) before quenching. The general operating steps are to place the die on a conveyor roller and transport it to a heat treatment furnace. The furnace is heated to a certain temperature through resistance, and the die is placed in the heat treatment furnace for a certain period of time to improve the performance of the die.

[0003] For example, in the Chinese patent application number 201920546254.1, a processing furnace for die quenching heat treatment is provided, in which a plurality of pillars are installed on the bottom surface of the furnace bottom plate, and the bottom surface of the pillars is hemispherical, and the bottom surface of the pillars is inlaid with ball bearings. The furnace bottom plate is supported by the pillars to reduce the contact area between the furnace bottom plate and the inner wall of the insulation furnace, and the sliding is converted into rolling by means of the ball bearings, thereby reducing friction and facilitating the furnace bottom plate to slide back and forth on the bottom of the inner wall of the insulation furnace.

[0004] However, this type of heat treatment furnace cannot clean the surface of the die during use. During the production of the die, oxygen comes into contact with the metal surface, resulting in an oxide layer on the surface of the die. When the die covered with the oxide layer enters the heat treatment furnace for heating, the oxide layer usually has a lower thermal conductivity, resulting in uneven heat conduction, affecting the uniformity and effect of the quenching process. This will cause uneven distribution of the hardness and strength of the die, affecting the use effect.

[0005] For this purpose, we propose a processing furnace for die quenching heat treatment. Summary of the invention

[0006] The purpose of the present invention is to solve the problem in the prior art that the surface of the die cannot be cleaned.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the setting of the top processing mechanism, before the die body is conveyed to the heating zone, the top of the die body can be processed to scrape off the oxide layer on the top of the die body to avoid the die body surface being covered with an oxide layer, resulting in uneven heat conduction, affecting the uniformity and effect of the quenching process, thereby causing uneven distribution of the hardness and strength of the die body, affecting the use effect; through the setting of the impact mechanism, while the top processing mechanism scrapes off the oxide layer on the top of the die body, the die body can also be impacted simultaneously, and vibration is generated by the impact, so that the oxide layer on the surface of the die body is easier to loosen, thereby improving the cleaning effect of the top processing mechanism, and the impact of the impact mechanism is coordinated to make the die body appropriately displaced. When the die body is displaced and rubs against the frosting pad, the oxide layer at the bottom of the die body can be scraped off, further avoiding the oxide layer from affecting the heat conduction of the die body.

[0022] 2. Through the setting of the side processing mechanism 1, when the impact mechanism impacts the die body, the mounting strip and the second frosting pad can be synchronously moved close to the front and rear sides of the die body. When the die body is displaced and rubbed against the second frosting pad, the oxide layer on the front and rear sides of the die body can be scraped off by the second frosting pad, thereby further reducing the influence of the oxide layer on the heat conduction of the die body. The pressure of the second frosting pad on the die body gradually increases. Using a smaller pressure at the beginning helps to reduce the mechanical damage to the surface of the die body. As the friction increases, the oxide layer can be gradually removed, reducing the impact on the die body, thereby reducing the risk of surface damage.

[0023] 3. Through the setting of the side processing mechanism two and the scraping part, when the impact mechanism impacts the die body and the side processing mechanism scrapes off the oxide layers on the front and rear sides of the die body, the frosting pad three can also be synchronously driven to slide on the surfaces of the left and right sides of the die body. The frosting pad three can be used to scrape off the oxide layers on the left and right sides of the die body, thereby again avoiding the influence of the oxide layer on the heat conduction of the die body. Through the setting of the blowing part, when the frosting pad three scrapes off the oxide layer, the left and right sides of the die body can be blown synchronously. Through the blowing of the fluid and the vibration effect of the impact mechanism, the oxide layers on the left and right sides of the die body can be removed more cleanly.

[0036] A top processing mechanism 6 is arranged in the processing area 3, and the top processing mechanism 6 is used to remove the oxide layer on the top of the die body 5;

[0037] An impact mechanism 7 mounted on the top processing mechanism 6, the impact mechanism 7 is used to remove the oxide layer on the front and rear sides of the die body 5;

[0038] The second side processing mechanism 8 is arranged on the impact mechanism 7, and the second side processing mechanism 8 is used to remove the oxide layer on the left and right sides of the die body 5.

[0039] Furthermore, the top processing mechanism 6 includes a cylinder 61 fixed in the processing area 3, a mounting shell 62 is fixed to the bottom end of the extension rod of the cylinder 61, a motor 63 is fixed to the top of the mounting shell 62, a rotating shaft 64 is fixed to the output shaft end of the motor 63, a turntable 65 is fixed to the bottom end of the rotating shaft 64, and a brush 66 is fixed to the bottom of the turntable 65.

[0040] Furthermore, the impact mechanism 7 includes a sector gear 71 fixed to the outer surface of the rotating shaft 64, the outer surface of the sector gear 71 is meshed with an arc-shaped rack housing 72, a U-shaped rod 73 is fixed on the arc-shaped rack housing 72, the U-shaped rod 73 is slidably connected to the mounting shell 62, a push shell 74 is fixed to one end of the U-shaped rod 73 away from the arc-shaped rack housing 72, and a fixing rod 75 is fixed to a side of the mounting shell 62 away from the U-shaped rod 73.

[0041] Furthermore, the impact mechanism 7 also includes a fixing bar 76 fixed to the end of the fixing rod 75 away from the mounting shell 62, a sliding bar 77 slides inside the fixing bar 76, an extrusion shell 78 is fixed to the end of the sliding bar 77 close to the pushing shell 74, a spring 79 is sleeved on the outer surface of the sliding bar 77, and the two ends of the spring 79 are respectively fixedly connected to the extrusion shell 78 and the fixing bar 76, and a side processing mechanism 70 is provided on the mounting shell 62.

[0042] When in use, the transport shell 41 is placed on the transport roller 4, and then the die body 5 is placed in the transport shell 41. The length of the transport shell 41 corresponds to that of the transport roller 4, which can ensure the stability of the transport shell 41 during transportation. By starting the transport roller 4 and driving the sealing door 21 to rise through the electric push rod, the transport shell 41 and the die body 5 are transported to the heating zone 2. The resistance element installed in the heating zone 2 increases the temperature in the heating zone 2, and the die body 5 is heated to improve the performance of the die body 5. This is the prior art, so it will not be described in detail here.

[0043] Considering that in the prior art, when the die body 5 is produced, oxygen contacts the metal surface, resulting in an oxide layer on the surface of the die body 5. When the die body 5 covered with the oxide layer enters the heat treatment furnace for heating, the oxide layer usually has a low thermal conductivity, resulting in uneven heat conduction, affecting the uniformity and effect of the quenching process. This will cause uneven distribution of the hardness and strength of the die body 5, affecting the use effect. The following improvements are now made:

[0044] Before the die body 5 is transported to the heating zone 2 for heating, it needs to pass through the processing zone 3. When the transport shell 41 and the die body 5 are transported to the bottom of the mounting shell 62, the transport roller 4 can be stopped, and the mounting shell 62 can be driven downward by the cylinder 61 to move the mounting shell 62 to the top of the die body 5, so that the brush 66 contacts the top of the die body 5, and the die body 5 is located between the pushing shell 74 and the extrusion shell 78. At this time, the motor 63 can be used to drive the rotating shaft 64 to rotate, and the rotating shaft 64 drives the turntable 65 and the brush 66 to rotate, so as to scrape off the oxide layer on the top of the die body 5. After scraping it clean, it is transported to the heating zone 2 for heating by the transport roller 4.

[0045] Considering that the oxide layer cannot be scraped off well by the brush 66 alone, a sector gear 71 is provided on the outer surface of the rotating shaft 64. When the rotating shaft 64 rotates, the sector gear 71 is also driven to rotate. When the healthy teeth on the sector gear 71 rotate to mesh with the healthy teeth on the rear side of the arc-shaped rack housing 72, the arc-shaped rack housing 72 is driven to move to the left. When the healthy teeth on the sector gear 71 rotate to mesh with the healthy teeth on the front side of the arc-shaped rack housing 72, the arc-shaped rack housing 72 is driven to move to the right. Therefore, when the sector gear 71 rotates, the arc-shaped rack housing 72 and the U-shaped rod 73 are driven to move left and right. The U-shaped rod 73 is slidably connected to the mounting shell 62 for limiting, so as to prevent the arc-shaped rack housing 72 from deviating when moving. The arc-shaped rack shell 72 is connected to the pushing shell 74 through the U-shaped rod 73. When the U-shaped rod 73 is driven to move left and right, the pushing shell 74 is also driven to move left and right. Since the die body 5 is located between the pushing shell 74 and the extrusion shell 78, when the pushing shell 74 moves and collides with the die body 5, it will hit the die body 5, causing the die body 5 to move toward the extrusion shell 78. The die body 5 is slidably connected to the fixed bar 76 through the slide bar 77. When the die body 5 moves to contact the extrusion shell 78, it will drive the extrusion shell 78 and the slide bar 77 to slide in the direction of the fixed bar 76, squeezing the spring 79. When the pushing shell 74 is reset, the elastic force of the spring 79 will also drive the extrusion shell 78 to reset, thereby pushing the die body 5 to move in the direction of the pushing shell 74.

[0046] A further advantage of adopting the above method is that when the die body 5 is squeezed by the push shell 74 and moves toward the extrusion shell 78, it will pass through the brush 66, so that the entire top of the die body 5 can be in contact with the brush 66, so that the oxide layer on the top of the die body 5 can be removed cleanly, and the impact of the push shell 74 on the die body 5 causes the die body 5 to produce appropriate vibrations, so that the oxide layer on the surface of the die body 5 is more easily loosened, thereby improving the cleaning effect of the brush 66. In addition, by installing a frosting pad 42 in the transport shell 41, when the die body 5 is displaced by the impact of the push shell 74, the bottom of the die body 5 will rub against the frosting pad 42, so that the oxide layer at the bottom of the die body 5 can be scraped off to prevent the oxide layer from affecting the heating of the bottom of the die body 5.

[0047] Example 2, refer to Figure 1-Figure 9 A processing furnace for die quenching heat treatment, comprising a furnace body 1, a heating zone 2 and a processing zone 3 are arranged in the furnace body 1, a sealing door 21 is arranged on the heating zone 2, an electric push rod for driving the sealing door 21 to open is installed in the furnace body 1, a transport roller 4 is arranged in the furnace body 1, a transport shell 41 is placed on the transport roller 4, a frosting pad 42 is fixed in the transport shell 41, a die body 5 is placed in the transport shell 41, and also includes:

[0048] A top processing mechanism 6 is arranged in the processing area 3, and the top processing mechanism 6 is used to remove the oxide layer on the top of the die body 5;

[0049] An impact mechanism 7 mounted on the top processing mechanism 6, the impact mechanism 7 is used to remove the oxide layer on the front and rear sides of the die body 5;

[0050] The second side processing mechanism 8 is arranged on the impact mechanism 7, and the second side processing mechanism 8 is used to remove the oxide layer on the left and right sides of the die body 5.

[0051] Furthermore, the side processing mechanism 70 includes a connecting rod 701 fixed to the front and rear sides of the mounting shell 62, a horizontal bar 702 is fixed to the end of the connecting rod 701 away from the mounting shell 62, a liquid storage cylinder 703 is fixed on the horizontal bar 702, an extrusion rod 704 slides inside the liquid storage cylinder 703, an oblique bar 705 is fixed to the end of the extrusion rod 704 away from the liquid storage cylinder 703, a spring 2 706 is sleeved on the outer surface of the extrusion rod 704, and the two ends of the spring 2 706 are respectively fixedly connected to the liquid storage cylinder 703 and the oblique bar 705.

[0052] Furthermore, the side processing mechanism 70 also includes a moving rod 707 fixed on the side of the oblique bar 705 close to the liquid storage cylinder 703, the moving rod 707 is slidably connected to the horizontal bar 702, a mounting bar 708 is fixed to the end of the moving rod 707 away from the oblique bar 705, a sanding pad 709 is fixed to the side of the mounting bar 708 away from the moving rod 707, an L-shaped rod 7010 is fixed to the outer surface of the U-shaped rod 73, an extrusion block 7011 is fixed to the end of the L-shaped rod 7010 away from the U-shaped rod 73, and the extrusion block 7011 corresponds to the position of the oblique bar 705.

[0053] Although the oxide layers at the bottom and top of the die body 5 can be scraped off by the top processing mechanism 6 and the impact mechanism 7, the oxide layers at the front and rear sides of the die body 5 are still not removed. The following improvements are now proposed:

[0054] The L-shaped rod 7010 is connected to the U-shaped rod 73. When the U-shaped rod 73 moves left and right, the L-shaped rod 7010 and the extrusion block 7011 are also driven to move left and right. Since the extrusion block 7011 corresponds to the position of the oblique bar 705, when the L-shaped rod 7010 moves to contact the oblique bar 705, it will exert a backward pressure on the oblique bar 705, thereby driving the extrusion rod 704 to slide backward in the liquid storage cylinder 703, squeezing the second spring 706, and connecting with the moving rod 707 through the oblique bar 705. The oblique bar 705 also drives the moving rod 707 to move backward, and is connected to the moving rod 707 through the installation bar 708. The moving rod 707 drives the installation bar 708 and the second frosting pad 709 to move toward the front and rear sides of the die body 5 until the second frosting pad 709 is aligned with the die body 5. The front and rear sides of the die body 5 are in contact with each other, and the push shell 74 can push the die body 5 to move in the direction of the extrusion shell 78. During the movement of the die body 5, the frosting pad 2 709 contacts the front and rear sides of the die body 5, and the front and rear sides of the die body 5 will generate friction with the frosting pad 2 709. The frosting pad 2 709 can scrape off the oxide layer on the front and rear sides of the die body 5, and the influence of the oxide layer on the heat conduction of the die body 5 is reduced again. The inclined setting of the oblique strip 705 gradually increases the pressure of the frosting pad 2 709 on the die body 5. Using a smaller pressure at the beginning helps to reduce the mechanical damage to the surface of the die body 5. As the friction increases, the oxide layer can be gradually removed, reducing the impact on the die body 5, thereby reducing the risk of surface damage.

[0055] It should be noted that when the mounting shell 62 moves downward, the die body 5 also needs to be located between the two second sanding pads 709 , so that when the die body 5 moves, friction can be generated between the second sanding pad 709 .

[0063] Through the arrangement of the top processing mechanism 6, the impact mechanism 7 and the side processing mechanism 70, although the oxide layers on the top, bottom and front and rear sides of the die body 5 can be removed, the oxide layers on the left and right sides are still not removed.

The piston plate 2 833 is impacted by the fluid and slides backward in the fixed cylinder 832. The piston plate 2 833 drives the propulsion rod 834 and the connecting block 836 to slide backward together, and squeezes the spring 3 835. The connecting block 836 is connected to the circular rod 837, and the circular rod 837 is connected to the rectangular bar 838. The connecting block 836 drives the circular rod 837 to move in the fixed cylinder 832. The circular rod 837 slides in the slide groove 8310, and the rectangular bar 838 and the frosting pad three 839 are driven to move together. When the pushing shell 74 pushes the die body 5, the pushing shell 74 and the extrusion shell 78 are in contact with the left and right sides of the die body 5. Therefore, the frosting pad three 839 will also be in contact with the left and right sides of the die body 5, and the frosting pad three 839 is moved by the squeezing of the fluid, thereby driving the frosting pad three 839 to move on the left and right sides of the die body 5. The friction between the frosting pad three 839 and the left and right sides of the die body 5 can scrape off the oxide layer on the left and right sides of the die body 5, thereby preventing the oxide layer from affecting the heat conduction of the die body 5.

[0065] It should be noted that the fluid can be either water or oil.

[0066] The hollow shell 842 and the fixed cylinder 832 are connected through the second hose 841. When the second piston plate 833 moves backward in the fixed cylinder 832, the gas in the fixed cylinder 832 will be squeezed, so that the gas can enter the hollow shell 842 through the second hose 841 and be ejected from the air outlet 843, and the left and right sides of the die body 5 can be blown synchronously. Through the blowing of the fluid and the vibration effect of the impact mechanism 7, the oxide layers on the left and right sides of the die body 5 can be removed more cleanly.
