Description

Technical Field

[0001] This utility model relates to the field of extrusion molding equipment technology, and in particular to a high-efficiency extrusion molding machine for aluminum profiles used in new energy vehicles. Background Technology

[0002] Aluminum profiles for new energy vehicles are one of the core materials for the lightweight development of new energy vehicles, and their application spans multiple key components such as body structure, battery system, chassis, and power system. Currently, aluminum profile extrusion equipment for new energy vehicles generally suffers from the following problems: traditional conveyor belts rely on friction for feeding, causing aluminum profiles to easily slip and stagnate, failing to accurately reach the processing position, and resulting in insufficient conveying power; profiles are prone to deviation when fed into the die, leading to extrusion deformation or dimensional errors; after forming, profiles easily adhere to the die, requiring manual intervention for removal, affecting continuous production; the feeding, pushing, and discharging processes are separated, resulting in poor equipment coordination and restricting production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problems in the prior art where the conveyor belt relies on friction to feed material, the aluminum profile is prone to slipping and stopping, cannot accurately reach the processing position, and has insufficient conveying power; the profile is prone to deviation when fed into the mold, resulting in extrusion deformation or dimensional error, so this utility model provides a high-efficiency extrusion molding machine for aluminum profiles for new energy vehicles.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a high-efficiency extrusion molding machine for aluminum profiles for new energy vehicles, including a worktable and a feeding unit, a pushing unit, a receiving unit, an extrusion unit and a discharging unit arranged on the worktable.

[0005] The feeding unit is used to transport the aluminum profile to be processed, the receiving unit is used to receive the aluminum profile to be processed transported by the feeding unit, the pushing unit pushes the aluminum profile to be processed on the receiving unit into the extrusion unit and pushes the aluminum profile onto the discharge unit after the extrusion unit has finished extruding and forming, and the discharge unit is used to output the formed aluminum profile.

[0006] The extrusion unit includes a frame, an extrusion drive, an upper extrusion die, and a lower extrusion die. The frame and the worktable are fixedly connected, the extrusion drive is fixedly connected to the frame, the output end of the extrusion drive is drivenly connected to the upper extrusion die, and the lower extrusion die is fixedly connected to the frame. The lower extrusion die is located below the lower extrusion die and has a forming cavity. A forming seat is elastically installed in the forming cavity. The pusher unit can move up and down. Through the linkage between the pusher unit and the elastic forming seat, it retracts to form a positioning processing area, forcibly aligning the aluminum profile and solving the problem of incomplete conveying. The guide rod's arc surface design reduces frictional resistance and assists the profile in sliding into the processing area.

[0007] When the pusher unit pushes the aluminum profile to be processed onto the extrusion die, the pusher unit contacts the forming seat, causing the forming seat to retract into the forming cavity to form the positioning and processing area of ​​the aluminum profile.

[0008] When the pushing unit pushes the formed aluminum profile out of the extrusion die, the pushing unit moves upward and pushes the formed aluminum profile.

[0009] To address the issue of high frictional resistance on the bottom surface when the profile is fed into the mold, which can easily cause scratches or jamming, the molding seat is further equipped with a guide rod. The top surface of the guide rod protrudes from the top surface of the extrusion die, and the top surface of the guide rod is an arc-shaped surface.

[0010] To address the issue of excessive retraction stroke of the forming seat leading to failure of the elastic element or misalignment of the positioning, the method further includes installing a limiting seat on the bottom surface of the forming seat, and providing a limiting groove communicating with the forming cavity inside the extrusion die. The limiting groove and the limiting seat are matched, with the limiting seat located within the limiting groove. The distance between the bottom surface of the limiting seat and the limiting groove is less than the height of the guide rod protruding from the extrusion die.

[0011] To address the issue of the molding seat needing to reset quickly but lacking reliable elastic support, the design further includes arranging an elastic element inside the molding cavity, with one end of the elastic element abutting against the extrusion die and the other end abutting against the molding seat.

[0012] To address the issue of low efficiency in traditional split mechanisms due to the need for combined lifting and translating motions in the pushing action, a further pushing unit is included, comprising a lifting drive, a pushing drive, and a pushing plate. The lifting drive is fixedly connected to the worktable, and the output end of the lifting drive is connected to the pushing drive via a transmission. The lifting drive provides power for the vertical movement of the pushing plate, and the pushing drive provides power for the horizontal movement of the pushing plate.

[0013] To address the issue of profile transfer angle deviation caused by a fixed receiving height, the receiving unit further includes a connecting seat, a receiving seat, and a receiving drive component. The connecting seat is fixedly connected to the worktable, and the receiving drive component is also fixedly connected to the worktable. The output end of the receiving drive component is connected to the receiving seat via a transmission connection. The receiving drive component provides power for the movement of the receiving seat. The connecting seat has a cavity for the movement of the receiving seat, and the receiving seat is located within the cavity.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a high-efficiency extrusion molding machine for aluminum profiles used in new energy vehicles. Through the linkage between the pushing unit and the elastic forming seat, the machine retracts to form a positioning processing area, forcibly aligning the aluminum profile and solving the problem of incomplete conveying. The arc surface design of the guide rod reduces frictional resistance and assists the profile to slide into the processing area. The pushing unit has both lifting and translation functions, and a single mechanism completes the entire process of feeding, extrusion positioning, demolding, and unloading, reducing equipment complexity. The pushing unit moves upward to eject the finished product, avoiding manual removal. The elastic element automatically resets the forming seat, ensuring continuous operation. The limit seat and limit groove control the retraction stroke of the forming seat, preventing damage to the elastic element due to overpressure. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] like Figure 1 This is a schematic diagram of the structure of the present invention. A high-efficiency extrusion molding machine for aluminum profiles for new energy vehicles includes a worktable 1 and a feeding unit 2, a pushing unit 3, a receiving unit 4, an extrusion unit 5 and a discharging unit 6 arranged on the worktable 1.

[0022] The feeding unit 2 is used to transport the aluminum profile to be processed. The feeding unit 2 is a conveyor belt. The conveying surface of the feeding unit 2 is higher than the top surface of the extrusion die 54. The receiving unit 4 is used to receive the aluminum profile to be processed transported by the feeding unit 2. The pushing unit 3 pushes the aluminum profile to be processed on the receiving unit 4 into the extrusion unit 5 and pushes the aluminum profile onto the discharge unit 6 after the extrusion unit 5 has been extruded and formed. The discharge unit 6 is used to output the formed aluminum profile. The discharge unit 6 is a conveyor belt. The conveying plane of the discharge unit 6 is flush with the top surface of the extrusion die 54.

[0023] like Figure 2 , 3 As shown, the extrusion unit 5 includes a frame 51, an extrusion drive 52, an upper extrusion die 53, and a lower extrusion die 54. The extrusion drive 52 can be a hydraulic cylinder. The frame 51 and the worktable 1 are fixedly connected. The output end of the extrusion drive 52 is connected to the upper extrusion die 53. The lower extrusion die 54 is fixedly connected to the frame 51. The lower extrusion die 54 is located below the upper extrusion die 55. The lower extrusion die 54 has a forming cavity 541. A forming seat 55 is elastically installed in the forming cavity 541. The pusher unit 3 can move up and down. The pusher unit 3 interacts with the elastic... The forming seat 55 is linked and retracts to form a positioning processing area, forcibly aligning the aluminum profile and solving the problem of incomplete feeding; the guide rod 551 has an arc surface design to reduce frictional resistance and assist the profile in sliding into the positioning processing area; the pushing unit 3 has both lifting and translation functions, and a single mechanism completes the entire process of feeding, extrusion positioning, demolding, and discharge, reducing equipment complexity; the pushing unit 3 moves upward to eject the finished product, avoiding manual removal; the elastic element 543 automatically resets the forming seat to ensure continuous operation; the limit seat 552 and the limit groove 542 control the retraction stroke of the forming seat 55 to prevent the elastic element 543 from being damaged by overpressure;

[0024] When the pusher unit 3 pushes the aluminum profile to be processed onto the extrusion die 54, the pusher unit 3 contacts the forming seat 55, causing the forming seat 55 to retract into the forming cavity 541 to form the positioning and processing area of ​​the aluminum profile.

[0025] When the pushing unit 3 pushes the formed aluminum profile out of the extrusion die 54, the pushing unit 3 moves upward and pushes the formed aluminum profile.

[0026] like Figure 2 , 3 As shown, the forming base 55 has a guide rod 551. The top surface of the guide rod 551 protrudes from the top surface of the extrusion die 54. The top surface of the guide rod 551 is an arc-shaped surface. The arc-shaped surface of the guide rod 551 reduces contact resistance, guides the profile to slide smoothly into the positioning processing area, and protects the surface of the profile.

[0027] like Figure 2 , 3As shown, a limiting seat 552 is installed on the bottom surface of the forming base 55. A limiting groove 542 communicating with the forming cavity 541 is opened in the extrusion die 54. The limiting groove 542 and the limiting seat 552 are matched. The limiting seat 552 is located in the limiting groove 542. The distance between the bottom surface of the limiting seat 552 and the limiting groove 542 is less than the height of the guide rod 551 protruding from the extrusion die 54. The limiting seat 552 and the limiting groove 542 cooperate to limit the retraction displacement, prevent overload and ensure reset accuracy.

[0028] An elastic element 543 is arranged inside the molding cavity 541. The elastic element 543 is a spring. One end of the elastic element 543 abuts against the extrusion die 54, and the other end abuts against the molding seat 55. The elastic element 543 provides a stable rebound force to ensure that the molding seat 55 automatically resets and operates continuously.

[0029] like Figure 2 , 3 As shown, the pushing unit 3 includes a lifting drive 31, a pushing drive 32, and a pushing plate 33. The lifting drive 31 is fixedly connected to the worktable 1. The output end of the lifting drive 31 is connected to the pushing drive 32. The lifting drive 31 provides power for the up-and-down movement of the pushing plate 33, and the pushing drive 32 provides power for the lateral movement of the pushing plate 33. By integrating the lifting and pushing drive 32, a single mechanism can complete multi-directional actions, simplifying the structure and improving the response speed. The lifting drive 31 can be a hydraulic cylinder, an electric actuator, etc., and the pushing drive 32 can be a hydraulic cylinder, an electric actuator, etc.

[0030] like Figure 2 , 3 As shown, the receiving unit 4 includes a connecting seat 41, a receiving seat 42, and a receiving drive component 43. The receiving drive component 43 can be a hydraulic cylinder, an electric actuator, etc. The connecting seat 41 is fixedly connected to the worktable 1, and the receiving drive component 43 is fixedly connected to the worktable 1. The output end of the receiving drive component 43 is connected to the receiving seat 42 for transmission. The receiving drive component 43 is used to provide power for the movement of the receiving seat 42. The connecting seat 41 has a cavity for the movement of the receiving seat 42. The receiving seat 42 is located in the cavity. The height of the receiving seat 41 is adjustable to adapt to different cross-sectional profiles, ensuring that it is fed horizontally into the processing position and avoiding large positional deviations when the aluminum profile falls.

[0031] Working process: The feeding unit 2 conveys the profile, and the receiving drive component 43 starts, causing the receiving seat 42 to rise, conveying the aluminum profile onto the receiving seat 42; the receiving drive component 43 adjusts the height of the receiving seat 42 so that the receiving seat 42 and the connecting seat 41 are flush; the pusher plate 33 moves laterally, pushing the aluminum profile into the extrusion die 54; at the same time, the pusher plate 33 presses down on the guide rod 551 of the forming seat 55, causing it to retract into the forming cavity 541, forming a closed positioning processing area, and then the pusher plate 3... 3. Retract and disengage from extrusion unit 5; extrusion drive component 52 drives extrusion upper die 53 to press down, cooperating with extrusion lower die 54 to complete the plastic deformation of the profile. During the extrusion process, limit seat 552 and limit groove 542 restrict the position of forming seat 55 to ensure the forming effect; after extrusion, push plate 33 moves up (it cannot contact guide rod 551 during the lateral process), and elastic element 543 lifts the formed aluminum profile to disengage from extrusion lower die 54; push plate pushes laterally to push the finished product to discharge unit 6 to be transported away from the equipment.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
