[0032] The metal profile extrusion device is a key equipment used in industrial production to form metal billets into the required profiles through extrusion dies. During the extrusion process, the metal billet that has obtained plasticity after heating is extruded through the extrusion die under high pressure to obtain a metal profile. During the extrusion process, the high-temperature metal billet will generate a lot of heat, causing the extrusion die to heat up. In traditional technology, the extrusion device usually discharges this part of heat energy directly into the environment through natural cooling or air cooling, resulting in energy waste and low equipment operation efficiency, which not only increases the energy consumption cost, but also aggravates the problem of environmental thermal pollution.

[0033] The cooling structure in a traditional extrusion device is usually directly installed on the extrusion die. When the extrusion die is replaced, the cooling system often needs to be adjusted or replaced simultaneously, which is complicated and time-consuming to operate and has low production efficiency.

[0034] The following is the attached Figure 1 To Attachment Figure 5 , describing the energy recycling metal profile extrusion device of the embodiment of the present invention, which can recycle heat energy and convert it into electrical energy, has high energy utilization rate, is energy-saving and environmentally friendly, and has little thermal pollution to the environment.

[0035] Reference Figures 1 to 5 , a metal profile extrusion device with energy circulation in this embodiment includes:

[0036] The extrusion assembly 100 includes a fixed seat 110, an extrusion die 120 and a heat exchange recovery module 130. The fixed seat 110 is provided with a positioning cavity 111 running through both sides, the extrusion die 120 is arranged in the positioning cavity 111, and the heat exchange recovery module 130 is arranged outside the fixed seat 110. The positioning cavity 111 in the fixed seat 110 is used to install the extrusion die 120, and the heat exchange recovery module 130 is installed outside the fixed seat 110. When different products need to be produced, only the extrusion die 120 needs to be replaced. Yes, there is no need to operate the heat exchange recovery module 130, which can effectively simplify the replacement operation, improve the replacement efficiency, and improve the stability of the device structure. The heat exchange recovery module 130 includes a thermoelectric conversion module 131, a heat dissipation extension 132 and a cooling fan 133. The hot end of the heat exchange recovery module 130 is connected to the fixing seat 110, and the heat dissipation extension 132 is provided with a plurality of cold ends of the heat exchange recovery module 130 that are evenly distributed. The heat exchange recovery module 130 is electrically connected to the cooling fan 133. The conductive terminal of the recovery module 130 is connected to the power connection end of the cooling fan 133, so that the heat recovery module 130 supplies power to the cooling fan 133. The electric energy generated by the thermoelectric effect directly drives the cooling fan 133 to work, which can effectively improve the energy utilization rate. The cooling fan 133 is located on one side of the heat dissipation extension 132. Preferably, the air outlet of the cooling fan 133 is directly opposite to the heat dissipation extension 132, so that the cooling fan 133 can accelerate the air flow around the heat dissipation extension 132, thereby effectively improving the heat exchange efficiency between the heat dissipation extension 132 and the ambient air, and can effectively reduce the temperature of the cold end of the thermoelectric conversion module 131, and can effectively ensure the temperature difference between the hot end and the cold end of the thermoelectric conversion module 131, and then can effectively ensure the voltage difference and the corresponding current formed, can effectively ensure the stability of the operation of the cooling fan 133, and can effectively ensure the cooling effect of the fixing seat 110 and the extrusion die 120 therein, thereby effectively improving the extrusion molding efficiency;

[0037] The sleeve assembly 200 includes a first linear drive module 210 and a sleeve pressing block 220. The sleeve pressing block 220 is connected to the first linear drive module 210. The first linear drive module 210 is located on one side of the fixed seat 110. The sleeve pressing block 220 is provided with an extrusion hole 221 running through both sides. The driving direction of the first linear drive module 210 is the same as the extension direction of the extrusion hole 221. The extension direction of the extrusion hole 221 is the same as the extension direction of the positioning cavity 111. The first linear drive module 210 is used to drive the sleeve pressing block 220 to reciprocate relative to the fixed seat 110. Specifically, the first linear drive module 210 is used to drive the sleeve pressing block 220 to move close to the fixed seat 110 so that the extrusion hole 221 is connected to the extrusion chamber of the extrusion mold 120.

[0038] The heat recovery module 130 is arranged on the fixed seat 110, and the hot end of the thermoelectric conversion module 131 is closely attached to the surface of the fixed seat 110, so that the heat energy on the surface of the fixed seat 110 during extrusion production can be collected, ensuring that the heat energy generated during the extrusion process can be efficiently transferred to the thermoelectric conversion module 131, which can effectively improve the heat recovery efficiency. The thermoelectric conversion module 131 uses the waste heat of the fixed seat 110 to convert and circulate into electrical energy and power the cooling fan 133, which reduces the consumption of external energy, and the recovered heat energy is effectively utilized, with high energy utilization rate, energy saving and environmental protection, and can reduce thermal pollution to the environment, that is, reduce the environmental heat load, and meet the requirements of green manufacturing and sustainable development; by setting a uniformly distributed heat dissipation extension 132 for the cold end of the thermoelectric conversion module 131, and cooperating with the cooling fan 133 to work with the heat dissipation extension 132, the cooling efficiency of the cold end facing the thermoelectric conversion module 131 can be effectively improved, ensuring that the temperature of the cold end of the thermoelectric conversion module 131 is always at a low level, and can maintain the temperature between the hot end and the cold end. The degree difference is reduced, thereby ensuring the stable output of electric energy of the thermoelectric conversion module 131. By ensuring the working performance of the cooling fan 133, the energy conversion cycle effect of the thermoelectric conversion module 131 can be further ensured, and a benign energy circulation effect can be formed. The cooling fan 133 does not directly act on the thermoelectric conversion module 131, but acts on the cold end of the thermoelectric conversion module 131 through the heat dissipation extension 132, which can avoid the hot end of the thermoelectric conversion module 131 from being affected by the cooling fan 133, thereby further improving the energy conversion efficiency of the thermoelectric conversion module 131; in addition, the extrusion die 120 is installed in the fixing seat 110 through the positioning cavity 111, and the heat exchange recovery module 130 is fixed outside the fixing seat 110. When replacing the extrusion die 120, there is no need to operate the heat exchange recovery module 130. The replacement operation is simple, the downtime is reduced, and the production efficiency is high. The design of the extrusion component 100 and the socket component 200 is compact and stable, which reduces the vibration and deformation of the equipment during operation, and further improves the stability and service life of the equipment.

[0039] Thermoelectric conversion module 131, also known as thermoelectric module, is usually composed of multiple thermocouples connected in series or in parallel. Based on the Seebeck effect, when two different conductors or semiconductor materials are connected to form a closed loop, when there is a temperature difference between the two connection points, an electromotive force will be generated in the loop, thereby forming a current. The hot end of the thermoelectric conversion module 131 is used to connect to the high-temperature end to absorb heat, and the cold end of the thermoelectric conversion module 131 is used to connect to the low-temperature end.

[0040] It can be understood that the heat exchange recovery module 130 also includes a cooling component 134. In each heat exchange recovery module 130, one end of each heat dissipation extension component 132 away from the thermoelectric conversion module 131 is connected to the cooling component 134, so that the cooling component 134 dissipates heat for the heat dissipation extension component 132, thereby cooling the cold end of the thermoelectric conversion module 131.

[0041] It can be understood that the cooling component 134 is a water tank that stores coolant, and one end of each heat dissipation extension component 132 away from the thermoelectric conversion module 131 is located in the coolant in the water tank. The coolant in the water tank can improve the cooling effect of the heat dissipation extension component 132, thereby improving the cooling and energy recovery effect of the thermoelectric conversion module 131, wherein the coolant can be cooling water.

[0042] Since the energy conversion rate collected by the thermoelectric conversion module 131 through the thermoelectric effect is low, the electric energy that can be supplied to the cooling fan 133 is limited. By adding a water tank storing coolant to cool the heat dissipation extension 132, the cooling effect of the heat dissipation extension 132 can be effectively improved, which can not only improve the cooling efficiency of the fixing seat 110, but also improve the energy recovery efficiency of the thermoelectric conversion module 131, thereby forming a virtuous circle, thereby effectively improving the efficiency of energy recycling.

[0043] It should be noted that in addition to being configured as a water tank for storing coolant, the cooling component 134 can also be configured as cooling cotton connected to a cold water supply device through a pipeline. Using cooling cotton with a small footprint to cool the heat dissipation extension 132 can effectively reduce the layout difficulty of the heat exchange recovery module 130 and reduce the design cost of the device.

[0044] It can be understood that multiple heat exchange recovery modules 130 are provided and evenly distributed outside the fixed base 110. By evenly distributing multiple heat exchange recovery modules 130 around the fixed base 110, the uniformity of the heat dissipation and cooling effect of the fixed base 110 can be effectively improved, thereby effectively improving the uniformity of cooling the extrusion die 120, and ultimately effectively improving the curing and molding effect of the metal profile product.

[0045] Specifically, the shape of the fixed seat 110 is an inverted quadrangular prism, and each side of the fixed seat 110 is provided with at least two evenly distributed heat exchange recovery modules 130, which can effectively ensure the cooling effect of the heat exchange recovery module 130 on the fixed seat 110, and the extension direction of the fixed seat 110 is the same as the extension direction of the positioning cavity 111, and the positioning cavity 111 runs through the two top surfaces of the fixed seat 110.

[0046] It can be understood that the heat dissipation extension 132 is a heat dissipation ceramic component, which can effectively increase the contact area with the ambient air, and the ceramic has good thermal conductivity and good heat exchange performance. The heat dissipation ceramic component can effectively improve the cooling performance of the cold end of the thermoelectric conversion module 131, thereby effectively improving the working performance of the thermoelectric conversion module 131, and then can effectively improve the indirect cooling effect on the extrusion die 120. In addition, ceramics have good insulation properties. By connecting the heat dissipation ceramic component to the cold end of the thermoelectric conversion module 131, the electrical performance of the thermoelectric conversion module 131 can be effectively ensured while improving the heat dissipation performance.

[0047] It can be understood that the heat exchange recovery module 130 also includes a voltage regulation module 135, and the thermoelectric conversion module 131 is electrically connected to the cooling fan 133 through the voltage regulation module 135, wherein the voltage regulation module 135 can be a boost module, and the low voltage generated by the thermoelectric conversion module 131 is converted into a voltage that can drive the cooling fan 133 to work through the boost module.

[0048] Specifically, the voltage regulating module 135 may be a voltage regulating module 135 such as an XL6009 boost module or an MT3608 boost module.

[0049] It can be understood that the extrusion assembly 100 also includes a rotating drive module 140 and a mold changing clamp 150. The end of the mold changing clamp 150 is provided with a clamping portion 151. The mold changing clamp 150 is connected to the rotating drive module 140. The rotating drive module 140 is used to connect and drive the mold changing clamp 150 to rotate. The mold changing clamp 150 is located on the side of the fixed seat 110 close to the sleeve pressure block 220. The movement path of the clamping portion 151 intersects with the connecting line between the fixed seat 110 and the sleeve pressure block 220, so that the mold changing clamp 150 can rotate the mold and send it between the fixed seat 110 and the sleeve pressure block 220.

[0050] When the extrusion die 120 needs to be installed, the clamping portion 151 of the die-changing clamping jaw 150 reaches the outside of the connection line between the fixed seat 110 and the sleeve pressing block 220, and the first linear drive module 210 drives the sleeve pressing block 220 to move away from the fixed seat 110, so that a gap is formed between the fixed seat 110 and the sleeve pressing block 220. At this time, the clamping portion 151 of the die-changing clamping jaw 150 is located outside the fixed seat 110 and the sleeve pressing block 220, and the extrusion die to be installed is moved by mechanical structure or manual means. 120 is placed into the clamping part 151 of the mold changing clamp 150, with high safety performance; the rotating drive module 140 drives the mold changing clamp 150 to rotate, so that the mold changing clamp 150 sends the extrusion mold 120 to between the fixed seat 110 and the sleeve pressing block 220, and the extrusion mold 120 is aligned with the positioning cavity 111; the first linear drive module 210 drives the sleeve pressing block 220 to move close to the fixed seat 110, and the sleeve pressing block 220 pushes the extrusion mold 120 into the positioning cavity 111 for installation.

[0051] It can be understood that a positioning flange 112 is provided in the positioning cavity 111, and the positioning flange 112 is located on the side of the extrusion die 120 away from the sleeve block 220. Along the extension direction of the positioning cavity 111, the projection of the positioning flange 112 is located outside the projection of the extrusion chamber of the extrusion die 120, which can avoid the positioning flange 112 from hindering the extrusion of the metal profile. A circular top pressure ring sleeve 222 is provided on the side of the sleeve block 220 close to the fixed seat 110, and the ring hole of the top pressure ring sleeve 222 is connected to the extrusion hole 221. The outer ring diameter of the top pressure ring sleeve 222 is less than or equal to the diameter of the positioning cavity 111, and the ring hole diameter of the top pressure ring sleeve 222 is greater than or equal to the input diameter of the extrusion chamber in the extrusion die 120, that is, the top pressure ring sleeve 222 can be plugged into the positioning cavity 111, and the ring hole of the top pressure ring sleeve 222 can make way for the injection of the heated molten metal billet into the extrusion chamber. Among them, the input diameter of the extrusion chamber refers to the diameter of one end used to input the molten metal billet, and the other end of the extrusion chamber is used to output the molten metal billet. The total cross-sectional area inside the extrusion chamber gradually decreases from the input to the output direction.

[0052] When you need to load the mold, refer to Figures 1 to 3 As shown, the rotary drive module 140 drives the die-changing clamp 150 to align the extrusion die 120 with the positioning cavity 111, the first linear drive module 210 drives the sleeve pressing block 220 and the top pressure ring sleeve 222 to push the extrusion die 120 into the positioning cavity 111, and the first linear drive module 210 drives the top pressure ring sleeve 222 to retreat to make way for the activity of the die-changing clamp 150; refer to Figure 4As shown, the rotary drive module 140 drives the mold changing clamp 150 to rotate so that the mold changing clamp 150 is disengaged from the position between the fixed seat 110 and the sleeve pressing block 220, and the first linear drive module 210 drives the sleeve pressing block 220 to move close to the fixed seat 110, and the top pressure ring sleeve 222 is inserted into the positioning cavity 111, further pushing the extrusion mold 120 to completely enter the positioning cavity 111, and the top pressure ring sleeve 222 and the positioning flange 112 abut against the opposite sides of the extrusion mold 120 to achieve positioning.

[0053] It can be understood that the clamping portion 151 is a U-shaped slot, the mold changing clamp 150 is an elastic structure, and the U-shaped slot passes through the opposite sides of the mold changing clamp 150 along the extension direction of the extrusion hole 221, which can ensure that the extrusion mold 120 can enter the positioning cavity 111 along the extension direction of the extrusion hole 221, and the U-shaped slot can make way for the movement of the extrusion ring sleeve, which can effectively improve the reliability of the overall movement of the device; the opening of the U-shaped slot is located at the end of the mold changing clamp 150, which can facilitate the removal and placement of the extrusion mold 120 from the U-shaped slot, and the removal, placement and replacement of the extrusion mold 120 are convenient.

[0054] It can be understood that the extrusion assembly 100 also includes a second linear drive module 160 and a die-changing push rod 170. The die-changing push rod 170 is connected to the second linear drive module 160. The die-changing push rod 170 is located on the side of the extrusion die 120 away from the sleeve block 220. The second linear drive module 160 is used to drive the die-changing push rod 170 to move along the extension direction of the extrusion hole 221 so that the die-changing push rod 170 can enter the positioning cavity 111. The movement path of the die-changing push rod 170 is located on one side of the extrusion chamber in the extrusion die 120, which can ensure that the die-changing push rod 170 can act on the body of the extrusion die 120, thereby pushing the extrusion die 120 out of the extrusion chamber, and can ensure that the die-changing push rod 170 can make way for the extrusion output of the metal profile.

[0055] When the extrusion die 120 needs to be replaced, the first linear drive module 210 drives the sleeve pressing block 220 to move away from the fixed seat 110, and the rotary drive module 140 drives the mold changing clamp 150 to rotate so that the clamping part 151 is aligned with the positioning cavity 111. The second linear drive module 160 drives the mold changing push rod 170 to move close to the sleeve pressing block 220, thereby pushing the extrusion die 120 from the positioning cavity 111 to the clamping part 151 of the mold changing clamp 150. After the rotary drive module 140 drives the mold changing clamp 150 to rotate, the extrusion die 120 can be sent to the outside of the fixed seat 110 and the sleeve pressing block 220, and the extrusion die 120 can be removed from the clamping part 151 by manual means, etc., with reliable operation and high safety performance.

[0056] The first linear drive module 210 and the second linear drive module 160 can be configured as a screw positioning module, a hydraulic cylinder or an electric cylinder, etc., which can realize linear drive positioning. The rotary drive module 140 can be configured as a rotary motor or a motor with a reduction structure, etc., which can realize rotary drive.

[0057] Specifically, the fixing base 110, the cooling fan 133, the cooling member 134, the rotary drive module 140 and the second linear drive module 160 are all connected to the frame, wherein, in order to more clearly show the internal structure of the extrusion assembly 100, Figures 1 to 4 This is a schematic diagram of the back of the rack. Figure 5 The figure shows the application of the rack.

[0058] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
