Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat treatment technology, specifically, a heat treatment system for workpiece processing. Background Technology
[0002] The application of heat treatment systems in workpiece processing stems from the need to optimize the properties of metallic materials. Through heating, holding, and cooling processes, heat treatment can significantly improve the mechanical properties of metals, such as hardness, strength, toughness, and wear resistance, to meet different process requirements. With the development of industrial technology, especially in high-end manufacturing fields such as automobiles, aerospace, and tool manufacturing, the performance requirements for workpieces are increasingly demanding. Traditional manual or simple heating and cooling methods can no longer meet the needs of precise control. Modern heat treatment systems combine automation technology, precise temperature control technology, and atmosphere control technology to ensure the consistency and high quality of workpieces throughout the entire heat treatment process while controlling key parameters such as temperature, time, and cooling rate. However, existing heat treatment equipment is relatively large, and some companies face space conflicts when introducing it later, leading to the need to rebuild the factory, resulting in high costs. Furthermore, the unreasonable spatial planning between various components leads to low overall processing efficiency. Utility Model Content

[0023] Example 1:
[0024] This embodiment provides a heat treatment system for workpiece machining, specifically as follows: Figures 1-3 As shown, the system includes an embedded foundation 11, a hoisting assembly 12, an air circulation furnace 13, a quenching assembly 14, a lifting assembly 15, a smoke exhaust assembly 16, and a furnace door assembly 17. The embedded foundation 11 is a base embedded in the ground. The material of the embedded foundation 11 is reinforced concrete with a concrete strength grade of C25, using HRB400 steel bars with a diameter of 15mm. It has a foundation pit, and support piles 112 and an installation platform 114 are installed in the foundation pit. A guardrail 113 is installed at the edge of the foundation pit. The hoisting assembly 12 is used for... The tooling 18 is used for hoisting and loading / unloading; the tooling 18 is used to load the workpiece, and the air circulation furnace 13 is used to heat the tooling 18; the quenching assembly 14 is used for the quenching operation of the tooling 18; the quenching assembly 14 is equipped with a fire extinguishing device to prevent the tooling 18 from catching fire during quenching; the lifting assembly 15 is used to lift the tooling 18 between the quenching assembly 14 and the air circulation furnace 13; the smoke exhaust assembly 16 is used to treat the smoke generated during the quenching of the tooling 18; and the furnace door assembly 17 is used to seal the air circulation furnace 13.
[0025] The hoisting assembly 12 is installed on the lower embedded foundation 11, the air circulation furnace 13 and the lifting assembly 15 are installed on the installation platform 114, the quenching assembly 14 is slidably disposed in the foundation pit, the smoke exhaust assembly 16 is installed in the foundation pit and located at the furnace door assembly 17, and the furnace door assembly 17 is installed on the support pile 112; the air circulation furnace 13 is located above the foundation pit, and the hoisting assembly 12 is partially located above the foundation pit and partially located outside the foundation pit.
[0026] When tooling 18 needs to be processed, the worker moves tooling 18 to below the hoisting assembly 12. The hoisting assembly 12 lifts tooling 18 from outside the pit and places it on the quenching assembly 14. The quenching assembly 14 moves to below the furnace door assembly 17, at which point the furnace door assembly 17 opens the furnace door. Then, the lifting assembly 15 lifts tooling 18 from the quenching assembly 14, placing tooling 18 in a preset position within the air circulation furnace 13. Afterward, the furnace door assembly 17 closes the furnace door; the air circulation furnace 13 then begins processing the tooling. 18 is heated evenly; after heating is completed, the furnace door assembly 17 opens the furnace door again, and the lifting assembly 15 lowers the tooling 18 so that the heated tooling 18 can begin quenching. At this time, the smoke exhaust assembly 16 and the fire extinguishing device are activated to prevent the high-temperature tooling 18 from generating flames and the smoke from leaking into the workshop during quenching; after quenching is completed, the quenching assembly 14 moves in the reverse direction to reset, and then the hoisting assembly 12 lifts the quenched tooling 18 and places it in the loading area, where it can be moved away by the staff. The overall processing efficiency is high.
[0027] With the above settings, the system can be installed in an embedded manner in existing factory buildings, reducing the height of the system protruding from the ground and avoiding the limitations imposed by the inherent height of the existing factory buildings. For companies that install the system after the factory buildings have been built, there is no need to rebuild the factory buildings, which greatly reduces the cost of use.
[0028] Example 2:
[0029] This embodiment further expands upon the quenching component 14 based on the above embodiment, specifically as follows: Figure 6 As shown, the quenching assembly 14 includes a trolley frame 142, on which rollers 145 and a drive source for driving the rollers 145 are mounted. The drive source can be a motor. It also includes a tooling rack 143 and a quenching tank 141. Multiple guide plates 144 are mounted on the tooling rack 143.
[0030] The tooling placement rack 143 is used to receive the tooling 18 lowered from the hoisting component 12. The guide plate 144 can guide and limit the tooling 18 to prevent it from shaking when the tooling placement rack 143 moves. The quenching tank 141 is used to hold quenching liquid. After the tooling 18 is heated, the lifting component 15 lowers it into the quenching tank 141. When the trolley frame 142 needs to move, the drive source drives the roller 145 to rotate, and the trolley frame 142 starts to move.
[0031] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0032] Example 3:
[0033] This embodiment further expands upon the quenching component 14 based on the above embodiment, specifically as follows: Figure 6 As shown, the fire extinguishing device includes a gas storage tank, a gas delivery pipe 146, and nozzles. The gas storage tank is mounted on the trolley frame 142. The gas delivery pipe 146 is connected to the gas storage tank. Multiple nozzles are mounted on the gas delivery pipe 146. The gas delivery pipe 146 forms a closed loop around the top of the quenching tank 141.
[0034] The gas stored in the gas storage tank can be either nitrogen or carbon dioxide, both of which are readily available and inexpensive. When the tooling 18 is quenched, due to the high temperature of the tooling 18, the quenching liquid may burn or even splash upon contact with the tooling 18. Therefore, during quenching, the gas in the gas storage tank is sprayed out from the nozzle through the gas delivery pipe 146. On the one hand, nitrogen or carbon dioxide is used to fill the vicinity of the tooling 18, isolating oxygen as much as possible to prevent combustion. On the other hand, the gas is sprayed from the nozzle from top to bottom, which can push the splashed droplets downwards and prevent the quenching liquid from splashing everywhere.
[0035] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0036] Example 4:
[0037] This embodiment further expands the hoisting component 12 based on the above embodiment, specifically as follows: Figure 5 As shown, the hoisting assembly 12 includes a hoisting frame 121, on which a platform 126 is slidably connected. A moving motor 123 and a winding motor 124 are mounted on the platform 126. A tooling hanger 122 is connected to the winding motor 124. A gear is mounted on the output shaft of the moving motor 123. A rack 125 is mounted on the hoisting frame 121, and the rack 125 meshes with the gear on the moving motor 123.
[0038] Start the winding motor 124, which lowers the tooling hanger 122. Then, the worker attaches the tooling hanger 122 to the tooling 18. The tooling hanger 122 then lifts the tooling 18. Next, start the moving motor 123. Through the meshing of the gear and rack 125, the platform 126 begins to move towards the air circulation furnace 13. When the platform 126 moves above the quenching assembly 14, the tooling hanger 122 lowers the tooling 18 into the pit, placing it on the tooling placement rack 143. Then, the tooling hanger 122 is detached from the tooling 18. After the tooling 18 is quenched, the tooling hanger 122 is attached to the tooling 18 again. Then, the tooling hanger 122 lifts the tooling 18 out of the pit and places it in the loading position. At this time, the tooling hanger 122 is detached from the tooling 18 once more. The worker can then remove the quenched tooling 18.
[0039] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0040] Example 5:
[0041] This embodiment further expands upon the smoke exhaust assembly 16 based on the above embodiment, specifically as follows: Figure 4 As shown, the smoke exhaust assembly 16 includes a housing 162, on which a smoke exhaust motor 164 is mounted. A fan blade is provided on the output shaft of the smoke exhaust motor 164 and placed in the housing 162. A smoke exhaust pipe 161 and a smoke extraction pipe 163 are connected to the housing 162, and a smoke extraction port 165 is installed on the smoke extraction pipe 163.
[0042] When tooling 18 is being quenched, the exhaust motor 164 is started. The fan blades rotate in the outer casing 162. At this time, the fan blades will draw in the smoke from the smoke inlet 165 and then discharge it through the exhaust pipe 161. The exhaust pipe 161 discharges the smoke outside the factory.
[0043] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0044] Example 6:
[0045] This embodiment further extends the embedded base 11 based on the above embodiment, specifically as follows: Figure 2 As shown, the lower embedded base 11 is provided with multiple reserved slots 111. The reserved slots 111 can be used for laying pipelines of equipment such as water pipes, gas pipes, and electrical control cabinets, hiding the lines within them and preventing the lines from becoming messy.
[0046] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.
[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
