Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing, and in particular to an integrated heat treatment and cooling device for an aluminum profile extrusion die. Background Art

[0002] In the process of producing aluminum profiles, the aluminum rod first needs to go through a heating stage, and then enter a special extrusion molding die for plastic deformation to form the required profile. However, the surface temperature of the aluminum profile after hot extrusion is still very high. In order to ensure the material performance and appearance quality, quenching and cooling treatment is required.

[0003] At present, the design of many aluminum profile extrusion devices tends to decompose these processes into independent processing links. This segmented operation mode not only lengthens the length of the entire production line and increases the time and cost of material transportation, but also leads to the failure to effectively utilize the heat energy generated during the heating, extrusion and cooling processes, resulting in a huge waste of energy. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides an integrated heat treatment and cooling device for an aluminum profile extrusion die, which can effectively solve the problem that heat energy cannot be effectively utilized during the production process of the existing aluminum profile extrusion device.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The present invention provides an integrated heat treatment and cooling device for an aluminum profile extrusion die, comprising a heating mechanism, a die frame is provided on one side of the heating mechanism, a plurality of groups of heat conducting pipes are fixedly installed on the periphery of the die frame, both ends of the heat conducting pipes are fixedly connected with connecting pipes, and a detection component for monitoring the temperature in the die frame is provided on the connecting pipes;

[0007] The detection component includes a fixed sleeve fixedly mounted on the connecting tube, an air bag fixedly connected between the connecting tube and the fixed sleeve, an annular block slidably mounted on the connecting tube, and the annular block is slidably inserted in the fixed sleeve, a sliding groove is opened on one side of the fixed sleeve, a sliding plate is fixedly mounted on the annular block, and the sliding plate is slidably inserted in the sliding groove, a temperature conduction box is fixedly mounted on all four sides of the mold frame, a temperature sensing liquid is filled in the temperature conduction box, a curved conduit is fixedly mounted on the temperature conduction box, a piston rod is slidably inserted at the end of the curved conduit, and the piston rod is fixedly connected to the sliding plate.

[0008] Furthermore, the temperature sensing liquid in the temperature conduction box expands or contracts as the temperature of the aluminum profile being detected changes, and the detection component then adjusts the flow rate of the water used for temperature control.

[0009] Furthermore, a support frame is sleeved on the mold frame, a connecting rod is fixedly connected between the mold frame and the support frame, a heat dissipation bellows is fixedly connected to the outside of the support frame, and a fan is arranged on the heat dissipation bellows.

[0010] Furthermore, a support frame is fixedly installed in the heat dissipation bellows, the cross-section of the support frame is square, and a plurality of groups of air guide plates are equidistantly rotatably installed on the support frame.

[0011] Furthermore, a fixing block is fixedly connected to the outside of the fixing sleeve, and a spring is fixedly connected between the sliding plate and the fixing block.

[0012] Furthermore, a sensing element is fixedly mounted on the sliding plate, and an infrared sensor for measuring the distance change of the sensing element is arranged on the fixed block.

[0013] Furthermore, a pushing mechanism is provided inside the heating mechanism, and a heat-insulating layer is provided outside the heating mechanism, and the heat-insulating layer is water-thermal temperature-controlled.

[0014] Furthermore, a water supply pipe is provided on the detection component between the heating mechanism and the mold frame, and a water collecting pipe is provided on the detection component on the mold frame away from the heating mechanism. The water supply pipe and the water collecting pipe have the same structure and are both fixedly connected to the connecting pipe.

[0015] Furthermore, a return pipe is fixedly connected to the water collecting pipe, and the return pipe is connected to the external insulation layer of the heating mechanism.

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0017] 1. The present invention sets a detection component. As the temperature of the aluminum profile changes, the airbag changes the inner diameter of the connecting pipe through its own expansion degree, thereby controlling the water flow rate per unit time in the connecting pipe, thereby adjusting the cooling speed of the aluminum profile. When the temperature of the aluminum profile rises, the sliding plate pushes the gas away from the airbag, causing the airbag to shrink and restore the inner diameter of the connecting pipe, so that a large amount of water flows quickly to take away the heat in the mold frame; when the temperature of the aluminum profile decreases, the sliding plate pushes the gas to move toward the airbag, causing the airbag to expand and shrink the inner diameter of the connecting pipe, so that the water flow rate slows down, thereby avoiding cracks or deformation at both ends of the aluminum profile due to the large temperature difference while eliminating internal stress due to rapid heat absorption.

[0018] 2. The present invention is provided with a return pipe for recycling waste heat. The water collecting pipe collects the water discharged from all the heat conducting pipes. The return pipe is connected with the water collecting pipe and the external insulation layer of the heating mechanism. The return pipe guides the heat exchange water back to the insulation layer, which is convenient for recycling waste heat, is beneficial to energy saving and environmental protection, and reduces production energy consumption.

[0019] 3. The present invention is also provided with a fan that utilizes wind power to assist in cooling. The detection component adjusts the blowing intensity of the fan according to the water temperature, and then the air guide plate rotates according to the different blowing intensities of the fan, and then the rotation speed is adjusted accordingly, thereby assisting the fan to enhance the wind power to cool the mold frame.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] The present invention will be further described below in conjunction with the embodiments.

[0031] Example: Refer to the attached Figure 1 —Attachment Figure 7 As shown, an integrated heat treatment and cooling device for an aluminum profile extrusion die comprises a heating mechanism 1, wherein an aluminum material is placed in the heating mechanism 1, and a heating furnace in the heating mechanism 1 heats the aluminum material. A pushing mechanism is arranged in the heating mechanism 1, and after the aluminum material is completely heated, the pushing mechanism pushes the aluminum material into a die frame 2.

[0032] A mold frame 2 is provided on one side of the heating mechanism 1. The aluminum material squeezed into the mold frame 2 is deformed into the shape set by the mold frame 2. A plurality of heat pipes 203 are fixedly installed on the periphery of the mold frame 2. By providing the heat pipes 203, the heat pipes 203 absorb the heat conducted to the mold frame 2 by the aluminum material, thereby reducing the temperature of the mold frame 2 and the aluminum profile. Figure 2 As shown, the dense S-shaped layout is conducive to the liquid having enough time to fully absorb heat; if the heat pipe 203 is set to be threadedly wound around the outside of the mold frame 2, this will cause the water flow path to be too long, the water flow extraction speed will be greatly limited, and the heat pipe 203 will bend at the corner of the square profile, which is not conducive to the flow of water; and this device is aimed at aluminum profiles with square cross-sections, so the present invention is provided with heat pipes 203 on the sides of the four sides of the mold frame 2, which is conducive to uniform and rapid heat absorption of the mold frame 2 and the aluminum profile.

[0033] Both ends of the heat-conducting pipe 203 are fixedly connected with connecting pipes 204. The connecting pipe 204 at one end close to the heating mechanism 1 is used to supply water into the heat-conducting pipe 203, and the connecting pipe 204 at the other end is used to extract the hot water in the heat-conducting pipe 203. A detection component for monitoring the temperature in the mold frame 2 is provided on the connecting pipe 204. The detection component controls the flow rate of water in the heat-conducting pipe 203 by detecting the temperature change in the mold frame 2, thereby gradually cooling the aluminum profile and eliminating the internal stress of the aluminum profile, thereby avoiding cracks or deformation of the mold due to overheating or overcooling.

[0034] Refer to the attached Figure 3 —Attachment Figure 6As shown, the detection component includes a fixed sleeve 401 fixedly mounted on the connecting pipe 204, the fixed sleeve 401 and the connecting pipe 204 form a closed space, an airbag 402 is fixedly connected between the connecting pipe 204 and the fixed sleeve 401, the airbag 402 is elastic, and the airbag 402 changes the inner diameter of the connecting pipe 204 by its own expansion degree, thereby controlling the water flow rate per unit time in the connecting pipe 204, thereby adjusting the cooling speed of the aluminum profile, and a ring block 403 is slidably mounted on the connecting pipe 204, and the ring block 403 is slidably inserted in the fixed sleeve 401, and the ring block 403 and The airbags 402 are filled with gas, and the annular block 403 controls the expansion degree of the airbag 402 by controlling the distribution of the gas. A sliding groove is provided on one side of the fixed sleeve 401, and a sliding plate 404 is fixedly installed on the annular block 403, and the sliding plate 404 is slidably inserted in the sliding groove. By setting the sliding plate 404, it is convenient to control the sliding of the annular block 403, that is, the sliding plate 404 controls the sliding of the annular block 403, so that the annular block 403 changes the expansion degree of the airbag 402, and then changes the inner diameter of the connecting pipe 204, thereby increasing the water flow rate in the connecting pipe 204.

[0035] Specifically, a temperature conducting box 405 is fixedly installed on all four sides of the mold frame 2, and a temperature sensing liquid is filled in the temperature conducting box 405. The temperature sensing liquid is a liquid that can expand as the surface temperature of the aluminum profile increases and contract as the surface temperature of the aluminum profile decreases. A curved conduit 406 is fixedly installed on the temperature conducting box 405. By setting a 90-degree turn shape of the curved conduit 406, it is beneficial to control the horizontal reciprocating movement of the piston rod after the temperature sensing liquid expands and rises due to heat. A piston rod is slidably inserted at the end of the curved conduit 406, and the piston rod is fixedly connected to the sliding plate 404. The expanded temperature sensing liquid pushes the piston rod to move toward the fixed block 407, thereby causing the sliding plate 404 to move horizontally; the temperature sensing liquid in the temperature conducting box 405 expands or shrinks as the temperature of the detected aluminum profile changes, and then the detection component adjusts the water flow rate for temperature control.

[0036] Furthermore, a fixed block 407 is fixedly connected to the outside of the fixed sleeve 401. The fixed block 407 is used to support a horizontally placed spring. A spring is fixedly connected between the sliding plate 404 and the fixed block 407. When the temperature-sensitive liquid expands as the surface temperature of the aluminum profile increases, the piston rod pushes the sliding plate 404 to move toward the fixed block 407, and the spring is compressed. When the temperature-sensitive liquid contracts as the surface temperature of the aluminum profile decreases, the spring releases its elasticity and pushes the sliding plate 404 to move in the opposite direction and reset.

[0037] Furthermore, the detection component monitors the temperature change of the surface of the aluminum profile in real time. The temperature-sensitive liquid expands as the surface temperature of the aluminum profile increases, and contracts as the surface temperature of the aluminum profile decreases. After the temperature-sensitive liquid expands and rises, it controls the horizontal movement of the piston rod. The horizontal movement of the piston rod pushes the sliding plate 404 to move toward the fixed block 407 and compresses the spring. Then, the sliding plate 404 drives the annular block 403 to slide in the fixed sleeve 401, and the annular block 403 draws gas toward the side away from the airbag 402, and the airbag 402 shrinks accordingly, so that the inner diameter of the connecting tube 204 is restored, thereby achieving the purpose of accelerating the water flow rate per unit time in the connecting tube 204, facilitating a large amount of flowing water to quickly enter the heat pipe 203, and perform heat exchange and cooling on the inside of the mold frame 2.

[0038] It should be noted that the monitoring objects of the detection components at the water inlet end and the water outlet end are different. The detection component at the water inlet end monitors the surface temperature of the aluminum profile, and its purpose is to monitor how much water is needed for heat exchange when extruding the aluminum profile. The monitoring object at the water outlet end is the water flow temperature. Its purpose is to open the pipe diameter to quickly guide the superheated water flow when the water temperature is overheated. After the water temperature drops, the pipe diameter is reduced to reduce the outflow of water in the heat pipe 203 by slowing down the water flow rate. Therefore, the two sets of detection components are placed opposite to each other, and the temperature conduction box 405 at the water outlet end is fixed on the fixed sleeve 401 at the water outlet end.

[0039] The regulating component at the water outlet monitors the water flow temperature in real time. When the water temperature drops to within the standard threshold, the temperature-sensitive liquid shrinks as the surface temperature of the detected aluminum profile decreases, and the spring releases its elasticity to push the sliding plate 404 to move in the opposite direction and reset. The sliding plate 404 pushes the gas toward the airbag 402, and the airbag 402 expands into the connecting tube 204. The airbag 402 shrinks the diameter of the connecting tube 204, thereby slowing down the water flow rate and preventing the aluminum profile from cracking due to excessive temperature difference at both ends.

[0040] A heat preservation layer is arranged outside the heating mechanism 1, and the heat preservation layer is water-heated temperature controlled. The warm water isolates the outside and the heating part of the heating mechanism 1, which is conducive to concentrating heat energy and reducing the loss of hot air.

[0041] Furthermore, a water supply pipe 3 is provided on the detection component between the heating mechanism 1 and the mold frame 2, and the water supply pipe 3 is connected to the water delivery pipe. The water supply pipe 3 evenly delivers the water in the water delivery pipe to each heat transfer pipe 203. A water collecting pipe 4 is provided on the detection component on the side of the mold frame 2 away from the heating mechanism 1. The water supply pipe 3 and the water collecting pipe 4 have the same structure, and the water supply pipe 3 and the water collecting pipe 4 are fixedly connected to the connecting pipe 204. The water collecting pipe 4 collects the water discharged from all the heat transfer pipes 203. A return pipe 5 is fixedly connected to the water collecting pipe 4, and the return pipe 5 is connected to the external insulation layer of the heating mechanism 1. The return pipe 5 re-directs the heat exchange water back to the insulation layer to facilitate the reuse of waste heat.

[0042] In the process of heat conduction pipe 203 absorbing heat, due to the long distance of heat conduction pipe 203, when cooling the mold frame 2, there will still be a certain problem of untimely heat dissipation. Figure 7 As shown, a support frame 201 is sleeved on the mold frame 2, and a connecting rod 202 is fixedly connected between the mold frame 2 and the support frame 201. The connecting rod 202 supports the mold frame 2 and connects with the support frame 201, and is beneficial to protect the heat pipe 203 from being squeezed. A heat dissipation bellows 205 is fixedly connected to the outside of the support frame 201, and a fan 206 is arranged on the heat dissipation bellows 205. A plurality of vents are arranged on the heat pipe 203. The heat dissipation bellows 205 guides the wind generated by the fan 206 to the entire mold frame 2 wrapped by the heat pipe 203 to cool down the temperature.

[0043] A support frame 207 is fixedly installed in the heat dissipation bellows 205. The cross-section of the support frame 207 is a square that fits the support frame 201. The support frame 207 is sleeved on the outside of the support frame 201. A plurality of sets of wind guide plates 208 are equidistantly installed on the support frame 207. When the wind blows, the wind guide plates 208 can rotate with the wind on the support frame 207, and then adjust the rotation speed according to the wind intensity, thereby assisting the fan 206 to enhance the wind force and facilitating the rapid flow of wind in the heat dissipation bellows 205.

[0044] Furthermore, a sensing member 408 is fixedly mounted on the sliding plate 404, and an infrared sensor for measuring the distance change of the sensing member 408 is provided on the fixed block 407. The infrared sensor detects the change in the distance between the sensing member 408 and the fixed block 407 in real time. The sensor transmits the detection result to the processing system in the form of an electrical signal and displays it on a display for manual observation. It is also convenient for adjusting the intensity of the air supplied by the fan 206 to the mold frame 2.

[0045] When the sliding plate 404 slides toward the fixed block 407, the distance between the sensing element 408 and the fixed block 407 is shortened, that is, the water temperature in the heat pipe 203 is too high. At this time, it is necessary to increase the intensity of the air supply from the fan 206 to the mold frame 2; conversely, when the sliding plate 404 slides away from the fixed block 407, the distance between the sensing element 408 and the fixed block 407 is increased, that is, the water temperature in the heat pipe 203 is reduced. At this time, the intensity of the air supply from the fan 206 to the mold frame 2 can be reduced, and the air supply from the fan 206 to the mold frame 2 can even be suspended.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
