Description
Technical Field
[0001] This invention belongs to the technical field of heat treatment equipment, and particularly relates to a heat treatment process and heat treatment system. Background Technology
[0002] Heat treatment is a metal heat processing technology that uses heating, holding, and cooling to obtain the desired microstructure and properties of materials in a solid state. From the Stone Age to the Bronze Age and Iron Age, the role of heat treatment was gradually recognized. Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing technologies, heat treatment generally does not change the shape or overall chemical composition of the workpiece, but rather imparts or improves its performance by altering the internal microstructure or the surface chemical composition. In the heat treatment of cylindrical workpieces, whether the workpiece is heated uniformly directly affects the processing effect. However, due to the high ambient temperature during heat treatment, which significantly impacts electronic control devices, it is technically challenging to use electronic control elements to make the workpiece roll back and forth during heat treatment to ensure uniform heating. Therefore, existing technologies generally do not employ other auxiliary measures and directly perform heat treatment on cylindrical workpieces. This, to some extent, affects the heat treatment effect of cylindrical workpieces. Therefore, there is a need for equipment that can uniformly heat cylindrical workpieces without the need for electronic control devices, thereby improving the heat treatment effect. Summary of the Invention
[0003] In view of this, the technical problem to be solved by the present invention is to provide a device that can uniformly heat a cylindrical workpiece without the participation of electronic control devices, thereby improving the heat treatment effect.
[0004] A heat treatment system includes two fixed rods and a rack. A sliding sleeve is slidably connected between the two fixed rods. An arc-shaped plate is slidably connected to the sliding sleeve, and a sliding ring is slidably connected to the arc-shaped plate. A rotating ring is rotatably connected to the sliding ring, and a rack is fixedly connected to the rotating ring. The rotating ring has two grooves. A workpiece to be treated is placed on the arc-shaped plate. Two bosses are welded onto the workpiece, and the two bosses can be inserted into the two grooves respectively. The rack can mesh with the rack, and the sliding ring can be fixed by screwing bolts into the arc-shaped plate.
[0005] It also includes a push rod fixed to the sliding sleeve.
[0006] It also includes a contact rod that is slidably connected to the arc plate, which can be fixed by screwing bolts into the arc plate.
[0007] It also includes an auxiliary part, on which multiple arc-shaped bosses are fixedly connected, and a transmission rod is fixedly connected to the contact rod. The arc-shaped plate is slidably connected to the sliding sleeve, and a first compression spring is fixedly connected between the arc-shaped plate and the sliding sleeve.
[0008] The height of the multiple arc-shaped bosses gradually increases from right to left.
[0009] The heat treatment process of the aforementioned heat treatment system includes the following steps:
[0010] Step 1: Weld the two bosses to both sides of the workpiece to be processed by welding.
[0011] Step 2: Fix the two fixing rods into a furnace with its own heat source for heat treatment of the workpiece by screwing bolts into the rack and the two fixing rods. Then slide the sliding sleeve between the two fixing rods.
[0012] Step 3: Place the cylindrical workpiece to be heat-treated on the arc plate, and rotate the workpiece on the arc plate at a certain angle until the two protrusions on the workpiece are aligned with the two grooves.
[0013] Step 4: Slide the sliding ring on the arc plate, so that the rotating ring gradually moves closer to the workpiece to be processed, until the two grooves on the rotating ring are respectively inserted into the positions of the two bosses;
[0014] Step 5: Gradually push the sliding sleeve into the furnace, then start the heat source inside the furnace and use the gradually increasing temperature inside the furnace to heat treat the workpiece.
[0015] Step Six: Periodically push the push rod to make the sliding sleeve slide, which in turn makes the rotating ring rotate on the toothed ring. Through the cooperation of the two grooves and two bosses, the workpiece to be treated is rotated at a certain angle, so that the workpiece to be treated can move in the furnace in a rolling posture during the heat treatment process.
[0016] Step 7: Remove the workpiece from the furnace and allow it to cool, thus completing the heat treatment operation. Attached Figure Description

[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 9 The diagram shows a schematic representation of an embodiment of the present invention that enables uniform heating of a cylindrical workpiece and improves the heat treatment effect.
[0028] A heat treatment system includes two fixed rods 101 and a rack 801. The two fixed rods 101 are slidably connected to the same sliding sleeve 102, allowing the sliding sleeve 102 to slide left-right on the two fixed rods 101. An arc-shaped plate 201 is slidably connected to the sliding sleeve 102, allowing the arc-shaped plate 201 to slide up-down on the sliding sleeve 102. A sliding ring 301 is slidably connected to the arc-shaped plate 201, allowing the sliding ring 301 to slide back-and-forth on the arc-shaped plate 201. A rotating ring 302 is rotatably connected to the sliding ring 301, and a toothed ring 303 is fixedly connected to the rotating ring 302. The rotating ring 302 has two grooves 304. The workpiece 501 to be processed is placed on the arc plate 201. Two bosses 502 are welded on the workpiece 501. The two bosses 502 can be inserted into the two grooves 304 respectively. The rack 801 can mesh with the rack ring 303. The sliding ring 301 can be fixed by screwing bolts into the arc plate 201. The two fixing rods 101 can be fixed in a furnace with its own heat source for heat treatment of the workpiece by screwing bolts into the rack 801 and the two fixing rods 101. Then, the sliding sleeve 102 is slid between the two fixing rods 101 to complete the installation of the equipment.
[0029] Before heat treatment of the workpiece 501, two bosses 502 are welded to both sides of the workpiece 501. Then, when using the equipment, the sliding sleeve 102 is slid between the two fixed rods 101, causing the sliding sleeve 102 to move out of the furnace. The cylindrical workpiece 501 to be heat treated is then placed on the arc-shaped plate 201. Since the arc-shaped plate 201 is an arc surface, the cylindrical workpiece 501 naturally sits at its lowest point. The workpiece 501 is then rotated a certain angle on the arc-shaped plate 201 until the two bosses 502 on the workpiece 501 align with the two grooves 304. The sliding ring 301 is then slid on the arc-shaped plate 201, causing the rotating ring 302 to gradually move closer to the workpiece 501 until the two grooves 304 on the rotating ring 302 are inserted into the positions of the two bosses 502. Finally, the sliding ring 301 can be rotated... The sleeve 102 is gradually pushed into the furnace body, and then the heat source inside the furnace is activated to heat treat the workpiece 501 by gradually increasing the temperature inside the furnace. During the heat treatment process, the sleeve 102 can be pushed periodically to slide between the two fixed rods 101, and the arc plate 201 moves synchronously with the sleeve 102. During the movement of the arc plate 201, the toothed ring 303 is gradually pushed by the rack 801 meshing with the toothed ring 303, which causes the rotating ring 302 to rotate on the toothed ring 303. Thus, through the cooperation of the two grooves 304 and the two bosses 502, the workpiece 501 to be treated is rotated at a certain angle, so that the workpiece 501 to be treated can move in a rolling posture inside the furnace body during the heat treatment process. This allows different positions of the workpiece 501 to receive heat from the heat source evenly, so that the workpiece 501 to be treated can be heated evenly, thus performing a more uniform and comprehensive heat treatment on the workpiece 501 and improving the heat treatment effect.
[0030] See Figure 1 The diagram shows a schematic representation of an embodiment of the invention that facilitates periodic movement of the arc-shaped plate 201.
[0031] It also includes a push rod 103 fixed to the sliding sleeve 102.
[0032] A slot can be left on the opening and closing door of the furnace body for the push rod 103 to pass through. Then, during the process of sending the arc plate 201 into the furnace body for heat treatment, the operator can manually push or pull the push rod 103 with heat insulation tools, so that the two fixed rods 101 of the sliding sleeve 102 slide together, thereby completing the subsequent operation of periodically rolling the workpiece 501 to be treated during the heat treatment process, improving the heat treatment effect.
[0033] See Figure 5 The diagram illustrates an embodiment of the present invention, further.
[0034] It also includes a contact rod 701 that is slidably connected to the arc plate 201, and the contact rod 701 can be fixed by screwing bolts into the arc plate 201.
[0035] After inserting the two grooves 304 on the rotating ring 302 into the positions of the two bosses 502, the operable contact rod 701 slides downward on the arc plate 201, thereby gradually contacting the cylindrical workpiece 501 to be processed and providing a certain pressure to the cylindrical workpiece 501. Then, the contact rod 701 is fixed by screwing bolts into the arc plate 201. The slight pressure provided by the contact rod 701 can ensure that the workpiece 501 to be processed can roll normally while preventing the workpiece 501 to be processed from moving between the rotating ring 302, which would cause the bosses 502 to detach from the two grooves 304. As a result, the bosses 502 will no longer be able to rotate synchronously with the rotating ring 302, ensuring that the rolling and heating operation of the workpiece 501 to be processed is stable.
[0036] See Figure 5 , Figure 6 and Figure 9 The diagram shows a further embodiment of the present invention that facilitates uniform contact between the workpiece 501 to be processed and the heat emitted by the heat source, thereby improving the heat treatment effect.
[0037] It also includes an auxiliary part 601, on which multiple arc-shaped bosses 602 are fixedly connected, and a transmission rod 702 is fixedly connected to the contact rod 701. The arc-shaped plate 201 is slidably connected to the sliding sleeve 102, and a first compression spring is fixedly connected between the arc-shaped plate 201 and the sliding sleeve 102.
[0038] After the contact rod 701 is fixed to the arc plate 201 by tightening bolts, during the subsequent movement of the sliding sleeve 102, the arc plate 201 will drive the contact rod 701 to move synchronously, thereby causing the transmission rod 702 to move synchronously with the contact rod 701. This causes the transmission rod 702 to gradually contact multiple arc-shaped protrusions 602. During the contact between the transmission rod 702 and an arc-shaped protrusion 602, the arc-shaped protrusion 602 will gradually push the transmission rod 702, causing the arc plate 201 to gradually slide on the sliding sleeve 102 against the elastic force of the first compression spring. This allows the workpiece 501 to undergo reciprocating up-and-down sliding motion during the rolling process, further facilitating the uniform contact between the workpiece 501 and the heat emitted by the heat source inside the furnace, thus improving the heat treatment effect.
[0039] See Figure 5 The diagram illustrates a further improved heat treatment effect according to an embodiment of the present invention.
[0040] The height of the plurality of arc-shaped bosses 602 gradually increases from right to left.
[0041] The arrangement of multiple arc-shaped bosses 602 with their heights gradually increasing from right to left allows the multiple arc-shaped bosses 602 to push the transmission rod 702 to slide to different heights as the sliding sleeve 102 moves and the transmission rod 702 gradually comes into contact with the multiple arc-shaped bosses 602. This further expands the movable trajectory of the workpiece 501 in the furnace without the need for an electric power source or electric components, thus facilitating more uniform contact between the workpiece 501 and the heat emitted by the heat source in the furnace and improving the heat treatment effect.
[0042] See Figure 5 , Figure 7 and Figure 8 The diagram shows an embodiment of the present invention that ensures stable transmission of the gear ring 303 and the rack 801.
[0043] The rack 801 is slidably connected to the arc plate 201, and the furnace body is provided with a slide rail that can slide up and down, in which the rack 801 is slidably connected.
[0044] As the sliding sleeve 102 slides between the two fixed rods 101, it drives the arc plate 201 to slide synchronously. As the gear ring 303 is gradually pushed and moved by the rack 801 meshing with the gear ring 303, the arc plate 201 will gradually slide on the rack 801. When the transmission rod 702 contacts an arc-shaped boss 602 and pushes the arc plate 201 to slide on the sliding sleeve 102, the arc plate 201 will drive the rack 801 to slide up and down synchronously. This ensures that the rack 801 is always at the same distance from the arc plate 201, guaranteeing the stable transmission effect of the gear ring 303 and the rack 801.
[0045] See Figure 3 , Figure 4 and Figure 7 The diagram shows an embodiment of the present invention that facilitates workers to accurately monitor the rotation of the rotating ring 302 inside the furnace.
[0046] It also includes a pusher 305 fixed to the rotating ring 302, a mating sleeve 403 fixed to the toothed ring 303, a sliding column 401 slidably connected to the mating sleeve 403, a contact ring 402 fixed to the sliding column 401, and a second compression spring fixed between the sliding column 401 and the mating sleeve 403.
[0047] When the operator pushes the push rod 103 from outside the furnace body, thereby pushing the sliding sleeve 102 to slide, the rotating ring 302 gradually slides on the sliding ring 301. During this process, the pushing part 305 gradually contacts the sliding column 401, causing the sliding column 401 to gradually overcome the elastic force of the second compression spring and slide on the mating sleeve 403. As the rotating ring 302 continues to rotate, the contact ring 402 and the mating sleeve 403 will collide once, giving the operator a different feeling compared to when the push rod 103 is pushed normally. This allows the operator to accurately grasp the meshing of the toothed ring 303 and the rack 801 from outside the furnace body, thus facilitating the operator to accurately grasp the rotation of the rotating ring 302 inside the furnace body.
[0048] See Figure 4 The diagram shows a schematic representation of an embodiment of the present invention that further facilitates workers to accurately monitor the rotation of the rotating ring 302 inside the furnace.
[0049] The propulsion unit 305 is provided with multiple parts.
[0050] The multiple pushers 305 increase the frequency of providing different sensations to the operator's hands, thereby making it easier for the operator to accurately grasp the rotation of the rotating ring 302 inside the furnace.
[0051] See Figure 5 A schematic diagram of an embodiment that facilitates subsequent cooling operations is shown, further.
[0052] The arc-shaped plate 201 has multiple air holes 202.
[0053] The multiple vents 202 allow the arc plate 201 to be removed from the furnace when the workpiece 501 needs to be cooled after the heat treatment is completed. Subsequently, when the workpiece 501 is cooled by a blower or other equipment, the multiple vents 202 can increase the air permeability of the arc plate 201, thereby reducing the impact of the arc plate 201 on the cooling process and improving the cooling effect.
[0054] The heat treatment process of the aforementioned heat treatment system includes the following steps:
[0055] Step 1: Weld the two bosses 502 to both sides of the workpiece 501 to be processed by welding.
[0056] Step 2: Fix the two fixing rods 101 into a furnace with its own heat source for heat treatment of the workpiece by screwing bolts into the rack 801 and the two fixing rods 101. Then slide the sliding sleeve 102 between the two fixing rods 101.
[0057] Step 3: Place the cylindrical workpiece 501 to be heat-treated on the arc plate 201, and rotate the workpiece 501 on the arc plate 201 at a certain angle until the two protrusions 502 on the workpiece 501 are aligned with the two grooves 304.
[0058] Step 4: Slide the sliding ring 301 on the arc plate 201, thereby causing the rotating ring 302 to gradually move closer to the workpiece 501 to be processed, until the two grooves 304 on the rotating ring 302 are respectively inserted into the positions of the two bosses 502.
[0059] Step 5: Gradually push the sliding sleeve 102 into the furnace body, then start the heat source inside the furnace body and use the gradually increasing temperature inside the furnace body to perform heat treatment on the workpiece 501 to be processed.
[0060] Step 6: Periodically push the push rod 103 to make the sliding sleeve 102 slide, which in turn makes the rotating ring 302 rotate on the toothed ring 303. The two grooves 304 and the two bosses 502 drive the workpiece 501 to be processed to rotate a certain angle, so that the workpiece 501 to be processed can move in the furnace in a rolling posture during the heat treatment process.
[0061] Step 7: Remove the workpiece (501) from the furnace and cool it to complete the heat treatment operation.
