Description

Technical Field

[0001] The invention relates to the technical field of copper bar processing, in particular to an extruder for recovering waste heat from continuous extrusion of copper bars. Background Art

[0002] Copper busbar, also known as copper busbar or copper busbar, is a long conductor with a rectangular cross section made of copper. The production and processing of copper busbar requires the use of an extruder. The extruder is the main equipment for metal extrusion processing. Extrusion processing is a method of forming metal by plastic pressure. The thickness of the copper busbar can be changed by the extruder, thereby obtaining a copper busbar of the required thickness.

[0003] The patent with publication number CN115318863A discloses a copper bar extruder with a preheating structure, including a base plate and a shell, the shell is fixedly connected to the top of the base plate, the bottom of the shell is set to be open, and an auxiliary mechanism is provided inside the shell; the auxiliary mechanism includes two reciprocating screws, the two reciprocating screws are distributed up and down in a straight line, the rear ends of the two reciprocating screws extend to the outside of the rear side of the shell, the front side of the shell is fixedly connected to a motor 1, the front ends of the two reciprocating screws extend to the outside of the front side of the shell and one of the reciprocating screws is fixedly connected to the output shaft of the motor 1, through grooves are provided on both sides of the shell, a copper bar body is provided on the inside of the two reciprocating screws, the two ends of the copper bar body respectively pass through two through grooves and extend to the outside of both sides of the shell, the two reciprocating screws The outside of the screw is provided with a sliding seat, and the sliding seat is connected to the reciprocating screw by a ball screw pair. The inner sides of the two sliding seats are fixedly connected with an electric heating plate. Through the design of components such as the motor 1, the reciprocating screw, the sliding seat and the electric heating plate, the device can have a preheating function, so that the copper bar body can be preheated before it is extruded, so that the ductility of the copper bar body can be increased, so that a certain extrusion efficiency can be increased during extrusion. At the same time, when the motor is working, the two reciprocating screws can be rotated at the same time, so that the two sliding seats can be continuously moved back and forth, which can drive the two electric heating plates to move continuously back and forth. In this way, there will be no heating dead angle before the copper bar body is preheated, and the copper bar body can be fully preheated.

[0004] In the above technical solution, the unprocessed copper busbar is preheated in advance by an electric heating plate, and the continuous extrusion process of the copper busbar will generate heat through friction to achieve plastic deformation of the metal. Therefore, during the extrusion process, the product outlet temperature is high, and there is also significant heat loss on the mold and cavity surface. At the same time, there is power loss in the electric heating plate. If the waste heat generated is not recovered, it will not only cause energy waste, but may also affect equipment stability and output safety. Therefore, there is an urgent need for an extruder that can recover the waste heat from continuous extrusion of the copper busbar to solve the above problems. Summary of the Invention

[0030] The connecting post is fixedly connected to the disk shaft correspondingly.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] (1) For the extruder for heat recovery and utilization of continuous extrusion forming of copper bars, the sliders loaded on the insulating mechanism are inserted into the track components and cooperate with them. The screw rod can make the slider slide along the limiting rod under the control of the second motor. Rotating the screw rod can drive the slider to translate, thereby adjusting the gap between the two extrusion rollers of each roller row mechanism and improving the adjustability of copper bar processing.

[0033] (2) For the extruder for heat recovery and utilization of continuous extrusion forming of copper bars, the communication on both sides of the wall panel is isolated, reducing the way of heat conduction from the processing heat of the roller row mechanism to the outside, avoiding the outward escape of internal copper chips through the plate slots. In addition, a flow fan is arranged on the surface of the outer wheel. When the insulating mechanism rotates, the flow fan can drive air to blow the components at this place, thereby reducing the damage of the adjusting component, the power mechanism and the cooling mechanism due to high temperature or impurity invasion and improving the protection performance.

[0034] (3) The extruder for the waste heat recovery and utilization of continuous extrusion forming of copper bars. The linkage component synchronously adjusts the wrap angle and tension of the belt through the telescopic movement of the elastic telescopic rod, so that the tension of the belt is always maintained in the optimal range, avoiding slipping caused by excessive looseness or connection overload caused by excessive tightness. With the design of the linkage component, the belt is dynamically tensioned and coordinately adjusted during the copper bar processing, improving the transmission stability during the adjustment of the extrusion roll gap.

[0035] (4) The extruder for the waste heat recovery and utilization of continuous extrusion forming of copper bars. The heat generated by the extrusion and friction of the copper bar by the roll row mechanism is carried away by the flow of cooling water, stabilizing the roll surface temperature of the extrusion roll during the continuous extrusion of the copper bar, improving the extrusion uniformity and the processing quality of the copper bar.

[0036] (5) The extruder for the waste heat recovery and utilization of continuous extrusion forming of copper bars. Through the centrifugal action of the rotation of the extrusion roll, the cooling water is dispersed into the upper side pipes through the roadway, cooling the upper roll surface of the extrusion roll. In this way, the cooling water can only act on the roll surface of the extrusion roll far from the copper bar side, avoiding directly acting on the copper bar when cooling the extrusion roll and preventing uneven heating during the processing, further improving the processing quality of the copper bar.

[0037] (6) The extruder for the waste heat recovery and utilization of continuous extrusion forming of copper bars. The coolant pumped into the pump-in tank enters the central pipe through the input pipe, then enters the side pipe through the roadway, and then precisely cools the roll surface of the extrusion roll. It is evenly injected into the output pipe through the through pipe, and the pumped coolant is collected by the pump-out tank and finally returned to the pump-in tank. The cooling system uniformly converges through multiple paths, thereby reducing the flow pressure of the water channel component, reducing the pressure loss, and effectively reducing the energy consumption.

[0038] (7) The extruder for the waste heat recovery and utilization of continuous extrusion forming of copper bars. Through the cooling mechanism, the pumped cooling water is transported to the preheating pipe of the input mechanism through the second conduit, and then the residual temperature transferred by the cooling water is used to gradually preheat the copper bar to be processed, effectively utilizing the heat and improving the energy utilization rate of copper bar processing.

[0039] (8) The extruder for the waste heat recovery and utilization of continuous extrusion forming of copper bars. The preheating pipes are arranged on the upper and lower sides of the area to be processed of the copper bar respectively, forming a lap channel for copper bar input. While preheating the copper bar, it can support and align the copper bar, enabling the copper bar to quickly align with the target when entering the extrusion component and improving the processing efficiency of the copper bar.

[0081] On the side of the wall plate 601 facing away from the roller row mechanism 5, three groups of track components are arranged corresponding to the roller row mechanism 5. Each group of track components includes a rail frame 603 fixedly connected to the wall plate 601. A middle block 604 is fixedly connected to the middle of the rail frame 603.

[0085] The communication component correspondingly penetrates through the heat insulation mechanism 7;

[0086] The connecting post 306 is correspondingly fixedly connected to the disk shaft 703.

[0087] The working principle of the present invention is as follows:

[0088] The power of each roller row mechanism 5 is connected to the power component in the power mechanism 3 through the heat insulation mechanism 7, so that the power of the roller row mechanism 5 is input from the outside. The heat insulation mechanism 7 realizes the adjustment operation on the roller row mechanism 5 from the outside through the track component on the wall panel mechanism 6. The loaded slider 706 on the heat insulation mechanism 7 is inserted into the track component and cooperates with it. The screw rod 607 can make the slider 706 slide along the limiting rod 605 under the control of the second motor 606. Rotating the screw rod 607 can drive the slider 706 to translate, thereby adjusting the gap between the two extrusion rollers 501 of each roller row mechanism 5 and improving the adjustability of copper bar processing;

[0089] The surface of the heat insulation mechanism 7 is coated with a high-temperature resistant coating. The receiving plate 701 of the heat insulation mechanism 7 can completely cover the plate groove 602 even during the adjustment process, thereby isolating the communication on both sides of the wall panel 601, reducing the heat conduction path of the processing heat of the roller row mechanism 5 to the outside, and preventing internal copper chips from escaping to the outside through the plate groove 602. In addition, a flow fan 705 is arranged on the surface of the outer wheel 704. When the heat insulation mechanism 7 rotates, the flow fan 705 can drive air to blow the components at this place, thereby reducing the damage of the adjustment component, the power mechanism 3 and the cooling mechanism 4 due to high temperature or impurity intrusion and improving the protection performance;

[0090] A linkage assembly is provided on one end side of the roller row mechanism 5 in the same group, which can realize the adaptive adjustment of the belt 307 drive system when the distance between the two extrusion rollers 501 of the roller row mechanism 5 changes dynamically. By respectively providing belt sleeves 308 on both sides of the middle of the belt 307, the belt sleeves 308 are elastically tensioned in a floating manner through the elastic telescopic rods 309. When the gap between the two extrusion rollers 501 is adjusted to cause a change in their center distance, the linkage assembly synchronously adjusts the wrap angle and tension of the belt 307 through the telescopic movement of the elastic telescopic rods 309, so that the tension of the belt 307 is always maintained within the optimal range, avoiding slipping caused by being too loose or connection overload caused by being too tight. With the design of the linkage assembly, the belt 307 is dynamically tensioned and coordinately adjusted during the copper bar processing, improving the transmission stability when the gap of the extrusion roller 501 is adjusted;

[0091] A water channel assembly is provided inside the extrusion roller 501. The water channel assembly is in a divergent channel shape. The central pipe 502 pumps circulating cooling water from the pumping tank 402 through the input pipe 506, and the side pipe 503 pumps out circulating cooling water from the pumping-out tank 404 through the output pipe 508. The heat generated by the extrusion and friction of the roller row mechanism 5 on the copper bar is carried away by the flow of the cooling water, stabilizing the roller surface temperature of the extrusion roller 501 during the continuous extrusion of the copper bar, improving the extrusion uniformity, and improving the copper bar processing quality;

[0092] By providing a divergent water channel assembly inside the extrusion roller 501, the central pipe 502 and the side pipe 503 are connected through the roadway 504. The cooling water in the extrusion roller 501 at the lower layer of the copper bar is mostly in the lower side pipe 503 under the action of gravity, cooling the lower roller surface of the extrusion roller 501. In the extrusion roller 501 at the upper layer of the copper bar, a gravity plate 505 for covering the roadway 504 is movably hinged through a rotating shaft at the port where the roadway 504 connects to the central pipe 502. Therefore, the cooling water near the copper bar surface is blocked by the gravity plate 505 and cannot fall into the lower side pipe 503, but is mostly in the central pipe 502. Through the centrifugal action of the rotation of the extrusion roller 501, the cooling water is dispersed to the upper side pipe 503 through the roadway 504 to cool the upper roller surface of the extrusion roller 501. In this way, the cooling water can only act on the roller surface of the extrusion roller 501 far from the copper bar side, avoiding directly acting on the copper bar when cooling the extrusion roller 501 and avoiding uneven heating during the processing, further improving the copper bar processing quality.

[0093] A connection component is provided at one end of the extrusion roller 501. The connection component includes an input pipe 506 and an output pipe 508, which realizes the dynamic distribution of the cooling medium during the operation of the extrusion roller 501, reduces the probability of coincidence of the coolant return path, and the coolant pumped into the pumping tank 402 enters the central pipe 502 through the input pipe 506, and then enters the side pipe 503 through the roadway 504, thereby accurately cooling the roller surface of the extrusion roller 501, and is uniformly injected into the output pipe 508 through the through pipe 509. The pumped coolant is collected by the pumping-out tank 404 and finally returns to the pumping-in tank 402. The cooling system reduces the flow pressure of the water channel component through multi-path uniform confluence, thereby reducing the pressure loss and effectively reducing the energy consumption.

[0094] Through the temperature reduction mechanism 4, the pumped cooling water is transported to the preheating pipe 202 of the input mechanism 2 through the second conduit 204, and then the residual temperature transferred by the cooling water is used to gradually preheat the copper bar to be processed, effectively utilizing the heat and improving the energy utilization rate of copper bar processing.

[0095] The preheating pipes 202 are arranged on the upper and lower sides of the area to be processed of the copper bar respectively to form a lap channel for copper bar input, which can support and align the copper bar while preheating the copper bar, so that the copper bar can quickly align with the target when entering the extrusion component, and improve the processing efficiency of the copper bar.

[0096] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
