Description

Technical Field

[0001] This invention relates to the field of machining, and more specifically to an operating method for a viscous damper component processing device. Background Technology

[0002] Viscous dampers are widely used in high-rise buildings, bridges, and seismic retrofitting of building structures. The main components of a viscous damper include a cylinder, piston rod, and piston. The cylinder is cut from seamless steel pipe and requires subsequent heat treatment to improve its mechanical properties.

[0003] Oxidation occurs during heat treatment, resulting in oxide scale forming on both the inner and outer walls. The oxide scale on the outer wall is relatively easy to remove, while the oxide scale on the inner wall is more difficult to remove completely, affecting subsequent treatment of the cylinder. Furthermore, when the ambient temperature is low, the cylinder temperature is also low. If the heating rate is too fast during heat treatment, it will affect the mechanical properties of the cylinder. Summary of the Invention

[0004] The purpose of this invention is to provide an operating method for a viscous damper component processing device to solve the problems mentioned in the background art.

The transfer and arrangement device has a feeding roller conveyor at its rear end and a discharging roller conveyor at its front end. The transfer and arrangement device includes a support frame and a lifting frame. Two support frames are symmetrically arranged on the base. Several positioning blocks are equidistantly arranged on each support frame. A cylinder is placed between two adjacent positioning blocks. A lifting frame, slidably connected to the base, is located between the two support frames. Several symmetrical lifting blocks are arranged on both sides of the lifting frame. The lifting blocks are located... Between two adjacent positioning blocks, when the lifting block rises, it lifts the cylinder above it and guides the cylinder into the gap between the next positioning block through its own inclined surface and the inclined surface on the positioning block; the positioning rotation device is mounted on the frame and is used to lift the cylinder between the positioning blocks away from the positioning blocks and seal both ends of the cylinder to isolate the inside of the cylinder from the outside atmosphere, and to center and rotate the cylinder; the heating device heats the cylinder on the positioning rotation device through a moving induction coil; the preheating and deoxygenation device is used to remove oxygen from the inside of the cylinder and preheat the cylinder.

[0006] Preferably, the transfer and arrangement device further includes a hydraulic cylinder and a slide block. The bottom of the lifting frame is provided with two rollers, the slide block is located below the rollers, and the slide block is provided with two triangular blocks that are tangentially in contact with the rollers. The slide block is slidably connected to the base and fixedly connected to the output shaft of the hydraulic cylinder. The four corners of the bottom of the lifting frame are provided with slide rods that are slidably connected to the base. The lifting block and the positioning block are both triangular structures.

[0007] Preferably, the positioning and rotating device includes a first slide and a second slide. Both the first slide and the second slide are slidably connected to the guide rail on the frame. A rack is fixedly connected to the top of both the first slide and the second slide, and a gear meshes between the two racks. The rack is slidably connected to the frame, and the gear is rotatably connected to the frame. Several rotating tubes are rotatably connected to both the first slide and the second slide. A conical turntable is fixedly connected to each rotating tube. The turntable is obliquely upward relative to the corresponding cylinder and close to the feeding roller. A sealing gasket is provided on the turntable to seal the two ends of the cylinder. A first motor is also fixedly connected to the first slide. A sprocket is fixedly connected to the output shaft of the first motor and to the rotating tube on the first slide. The sprockets are connected by a chain. A second hydraulic cylinder is fixedly connected to the frame, and the output shaft of the second hydraulic cylinder is fixedly connected to the second slide.

[0008] Preferably, the heating device includes a sliding plate and a second motor. A plurality of induction coils are fixedly connected to the sliding plate. The induction coils are coaxially arranged with the turntable. The second motor is fixedly connected to the frame, and a lead screw is fixedly connected to its output shaft. The lead screw is threadedly connected to the sliding plate. An optical axis is provided on each side of the lead screw. The optical axis is fixedly connected to the frame, and the sliding plate is slidably connected to the optical axis.

[0009] Preferably, the preheating and deoxygenation device includes a combustion chamber, which is a tube structure with openings at the top and bottom.

A fan is also provided below the ignition gun.

[0010] The advantages of this invention are:

[0011] The transfer and arrangement device can automatically transfer the cylinders on the feeding channel and arrange them in an equidistant state for positioning and rotation device to use for positioning.

[0012] When the two turntables are aligned and clamp the cylinder, the conical structure of the turntables can be used to automatically lift the cylinder towards the upward direction of the feeding roller, so that the cylinder automatically moves away from the positioning block, ensuring that the induction coil can move in a straight line while the cylinder is in place.

[0013] The preheating and deoxygenation device, used in conjunction with a turntable with a rotating tube, can remove oxygen from the cylinder after sealing by taking advantage of the oxygen-consuming characteristics of combustion. This reduces the oxide scale that appears inside the cylinder during heat treatment. Furthermore, by heating the heat-conducting plate, the circulating hot air can preheat the inside of the cylinder, avoiding the effects of excessively rapid temperature rise during induction heating.

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

The transfer and arrangement device 3 includes a support frame 31 and a lifting frame 32. Two support frames 31 are symmetrically arranged on the base 2. Several positioning blocks 311 are equidistantly arranged on each support frame 31. The cylinder is placed between two adjacent positioning blocks 311. A lifting frame 32, slidably connected to the base 2, is located between the two support frames 31. Several symmetrical lifting blocks 321 are arranged on both sides of the lifting frame 32. Block 321 is located between two adjacent positioning blocks 311. When the lifting block 321 rises, it lifts the cylinder above it and guides the cylinder into the gap between the next positioning block 311 through its own inclined surface and the inclined surface on the positioning block 311. The positioning rotation device 4 is mounted on the frame 1 and is used to lift the cylinder between the positioning blocks 311 away from the positioning blocks 311, and seal both ends of the cylinder to isolate the inside of the cylinder from the outside atmosphere, and to center and rotate the cylinder. The heating device 5 heats the cylinder on the positioning rotation device 4 through a moving induction coil 53. The preheating deoxygenation device 6 is used to remove oxygen from the inside of the cylinder and preheat the cylinder.

[0027] In this embodiment, the transfer and arrangement device 3 further includes a hydraulic cylinder 33 and a slide block 34. The bottom of the lifting frame 32 is provided with two rollers 35. The slide block 34 is located below the rollers 35. The slide block 34 is provided with two triangular blocks that are tangentially in contact with the rollers 35. The slide block 34 is slidably connected to the base 2 and fixedly connected to the output shaft of the hydraulic cylinder 33. The four corners of the bottom of the lifting frame 32 are provided with slide rods 36 that are slidably connected to the base 2. The lifting block 321 and the positioning block 311 are both triangular structures.

[0028] In this embodiment, the positioning and rotating device 4 includes a first slide 41 and a second slide 42. Both the first slide 41 and the second slide 42 are slidably connected to the guide rail 11 on the frame 1. A rack 43 is fixedly connected to the top of each of the first slide 41 and the second slide 42, and a gear 44 meshes between the two racks 43. The racks 43 are slidably connected to the frame 1, and the gears 44 are rotatably connected to the frame 1. A plurality of rotating tubes 45 are rotatably connected to each of the first slide 41 and the second slide 42, and fixed on each of the rotating tubes 45... A conical turntable 46 is connected to the machine frame 1. The turntable 46 is obliquely upward relative to the corresponding cylinder body and close to the feeding roller 7. The turntable 46 is provided with sealing gaskets that seal the two ends of the cylinder body. A motor 47 is also fixedly connected to the slide 41. A sprocket 48 is fixedly connected to the output shaft of the motor 47 and the rotating tube 45 on the slide 41. The sprocket 48 is connected by a chain. A hydraulic cylinder 49 is fixedly connected to the frame 1. The output shaft of the hydraulic cylinder 49 is fixedly connected to the slide 42.

[0029] In this embodiment, the heating device 5 includes a slide plate 51 and a second motor 52. A plurality of induction coils 53 are fixedly connected to the slide plate 51. The induction coils 53 are coaxially arranged with the turntable 46. The second motor 52 is fixedly connected to the frame 1, and its output shaft is fixedly connected to a lead screw 54.

The slide plate 51 is slidably connected to the optical axis 55. The first slide 41 and the second slide 42 are provided with round holes for the optical axis 55 and the lead screw 54 to pass through.

[0030] In this embodiment, the preheating and deoxygenation device 6 includes a combustion chamber 61, which is a tubular structure with openings at the top and bottom. An ignition gun 62 and a heat-conducting plate 63 are installed inside the combustion chamber 61. The gas supply end of the ignition gun 62 is connected to a gas cylinder via a flexible hose. The gas cylinder contains combustible gas. The ignition gun 62 is located below the heat-conducting plate 63. The top of the combustion chamber 61 has an upper cover 64, and the bottom has a lower cover 65. The upper cover 64 has an outlet pipe 641, and the lower cover 65 has an inlet pipe 651. The outlet pipe 641 is connected to a rotating pipe 45 on a slide 1 41 via a rotary joint, and the inlet pipe 651 is also connected to a rotating pipe 45 on a slide 2 42 via a rotary joint. A fan 66 is also installed below the ignition gun 62, with the fan blowing air from bottom to top. This allows air from the cylinder to be drawn into the combustion chamber 61 for combustion and oxygen consumption, and the heated airflow after oxygen consumption is then sent back into the cylinder.

[0031] Working process and its principle:

[0032] The cylinder is placed on the feeding roller 7. During feeding, the output shaft of the hydraulic cylinder 33 extends, causing the slide 34 to move to the right. At this time, the roller 35 moves upward along the inclined surface of the triangular block on the slide 34, thereby causing the lifting frame 32 to move upward as a whole. The upward movement of the lifting frame 32 causes the lifting block 321 to move upward. The lifting block 321 lifts the cylinder in the feeding roller 7 until the lowest end of the lifting block 321 is higher than the end of the feeding roller 7. Then the cylinder will roll down from the lifting block 321 and fall between the first positioning block 311 and the second positioning block 311 for positioning and support. The cylinders behind are blocked by the lifting block 321 and cannot continue to roll down from the feeding roller 7.

[0033] Then the output shaft of hydraulic cylinder 33 shortens, slide 34 resets, lifting block 321 descends, and another cylinder rolls to the end of the feeding track 7. The above process is repeated. The cylinder that was originally between the first positioning block 311 and the second positioning block 311 moves to between the second positioning block 311 and the third positioning block 311, and so on. Eventually, there will be a cylinder between all the positioning blocks 311.

[0034] Subsequently, hydraulic cylinder 49 drives slide 42 to move towards the center. The rack 43, which is fixedly connected to slide 42, drives gear 44 to rotate, thereby causing slide 41 to move towards the center synchronously. The turntable 46 is not coaxial with the cylinder body, but is instead set obliquely upward close to the feeding roller 7. This allows the cylinder body to be forced to be coaxial with the turntable 46 when it is inserted into both ends of the cylinder body, and to be raised obliquely upward, causing the cylinder body to move away from the positioning block 311, thus reserving a position for the induction coil 53 to move.

[0035] When the two turntables 46 clamp the cylinder block, the inside of the cylinder block is isolated from the outside atmosphere, and outside air cannot enter the cylinder block. Then, the ignition gun 62 ignites and burns in the combustion chamber 61. During the combustion process, the oxygen in the combustion chamber 61 is consumed. The fan 66 creates an upward airflow in the combustion chamber 61, thereby guiding the air in the cylinder block into the combustion chamber 61. The heat conduction plate 63 is heated. The hot airflow that has consumed oxygen blows from one end of the cylinder block to the other end, and then enters the combustion chamber 61 through the air intake pipe, realizing circulation. This preheats the cylinder block while continuously consuming oxygen. After the oxygen is exhausted, the ignition gun 62 will automatically shut off due to the lack of oxygen. The thermocouple built into the ignition gun 62 detects the flame extinguishing and automatically shuts off the gas supply line for combustible gas, stopping the release of combustible gas.

[0036] Then, motor 47 starts, and drives all the rotating tubes 45 on slide 41 to rotate through sprocket 48 and chain. Turntable 46 rotates accordingly, and cylinder body also rotates. At the same time, motor 52 starts, and drives slide plate 51 to move along the axis of cylinder body through lead screw 54. The corresponding induction coil 53 can perform induction heating on cylinder body to complete subsequent heat treatment.

[0037] After heat treatment, the transfer and arrangement device 3 is restarted. Similarly, the treated cylinder body on the positioning block 311 is transferred to the unloading roller 8, making it convenient to transfer the treated cylinder body to other processes.

[0038] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative and not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.

The inlet pipe (651) is also connected to the rotating pipe (45) on the second slide (42) through a rotary joint. A fan (66) is also provided below the ignition gun (62). The specific operation method of the processing device is as follows: Step 1: The cylinder body is placed on the feeding roller (7). During feeding, the output shaft of hydraulic cylinder 1 (33) extends, and the slide (34) moves to the right. At this time, the roller (35) will move upward along the inclined surface of the triangular block on the slide (34), and the lifting frame (32) moves upward as a whole. The upward movement of the lifting frame (32) causes the lifting block (321) to move upward. The lifting block (321) lifts the cylinder body in the feeding roller until the lowest end of the lifting block (321) is higher than the end of the feeding roller. Then, the cylinder body will roll off the lifting block (321) and fall to the first positioning block (311) and the second positioning block (321). Between blocks (311), the cylinder behind is blocked by the lifting block (321) and cannot continue to roll down from the loading roller (7). Then the output shaft of hydraulic cylinder one (33) shortens, the slide (34) resets, the lifting block (321) descends, and another cylinder rolls to the end of the loading roller (7). The above process is repeated. The cylinder that was originally between the first positioning block (311) and the second positioning block (311) moves to between the second positioning block (311) and the third positioning block (311).

The rack (43) fixedly connected to slide 2 (42) drives gear (44) to rotate. Slide 1 (41) moves towards the middle in sync. When turntable (46) is inserted into both ends of cylinder, cylinder is forced to be coaxial with turntable (46) and is lifted obliquely upward, causing cylinder to move away from positioning block (311) and leaving a reserved position for induction coil (53) to move. Step 3: The two turntables (46) clamp the cylinder body, isolating the inside of the cylinder body from the outside atmosphere. Then the ignition gun (62) ignites the cylinder body and burns in the combustion chamber (61). During the combustion process, the oxygen in the combustion chamber (61) is consumed. The fan (66) causes an airflow from bottom to top in the combustion chamber (61), thereby guiding the air in the cylinder body to the combustion chamber (61). The heat conduction plate (63) is heated. The hot airflow that has consumed oxygen blows from one end of the cylinder body to the other end, and then enters the combustion chamber (61) through the air inlet pipe to achieve circulation. Thus, the cylinder body is preheated while oxygen is continuously consumed. After the oxygen is exhausted, the ignition gun (62) will automatically shut off due to lack of oxygen. The ignition gun (62) automatically closes the gas supply line of the combustible gas and stops releasing the combustible gas. Step 4: Motor 1 (47) starts, and drives the rotating tube (45) on slide 1 (41) to rotate through the sprocket (48) and chain. The turntable (46) rotates accordingly, and the cylinder also rotates.
