DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0020] See also Figures 1 to 6 As shown, an embodiment of the coil bending and forming equipment provided by the present invention.

[0021] The coil bending and forming equipment includes: Total bracket 1; A first pressing system 2, the first pressing system 2 is installed on the main bracket 1, and the first pressing system 2 includes a first carrier positioning mechanism 21 and a first coil pressing mechanism 22, the first carrier positioning mechanism 21 is used for detachably connecting the carrier 10, and the first coil pressing mechanism 22 is used for applying pressure to the coil in the carrier 10 on the first carrier positioning mechanism 21 so that the coil is bent into a set shape; A heating system 3, the heating system 3 is installed on the main bracket 1, and the heating system 3 is used to heat the coil in the carrier 10 on the first carrier positioning mechanism 21 to a first set temperature; The second pressing system 4 is installed on the main bracket 1. The second pressing system 4 includes a second carrier positioning mechanism 41 and a second coil pressing mechanism 42. The second carrier positioning mechanism 41 is used for detachably connecting the carrier 10. The second coil pressing mechanism 42 is used for applying pressure to the coil in the carrier 10 on the second carrier positioning mechanism 41 so that the coil maintains the set shape until the coil is cooled to the second set temperature.

[0022] The carrier 10 is used to support the coil and position the coil, that is, the carrier 10 limits the horizontal displacement of the coil it supports. The first carrier positioning mechanism 21 is used to support the carrier 10 and keep the carrier 10 in the hot pressing station, that is, the first carrier positioning mechanism 21 limits the horizontal displacement of the carrier 10 it supports. The second carrier positioning mechanism 41 is used to support the carrier 10 and keep the carrier 10 in the cold pressing station, that is, the second carrier positioning mechanism 41 limits the horizontal displacement of the carrier 10 it supports. The first coil pressing mechanism 22 applies pressure to the coil in the carrier 10 on the first carrier positioning mechanism 21, thereby pushing the coil to bend and deform to a set shape at the bent position. The bent position is a strip area. After the coil is bent, the bending mark of the strip area is the crease. The second coil pressing mechanism 42 applies pressure to the coil in the carrier 10 on the second carrier positioning mechanism 41 so that the coil maintains a set shape during the cooling process.

[0023] Specifically in this embodiment, the carrier 10 is provided with a first groove 101, and the coil is accommodated in the first groove 101. The first carrier positioning mechanism 21 and the second carrier positioning mechanism 41 are both fixedly connected to the main bracket 1, and can be conventionally connected by welding connection or bolt connection. The first carrier positioning mechanism 21 is provided with a second groove 211, and the second groove 211 is provided with a positioning pin 212. The carrier 10 is arranged in the second groove 211, and is positioned with the carrier 10 through the positioning hole and the positioning pin 211. The second carrier positioning mechanism 41 has the same structure as the first carrier positioning mechanism 21. The first coil pressing mechanism 22 is arranged above the first carrier positioning mechanism 21, and the second coil pressing mechanism 42 is arranged above the second carrier positioning mechanism 41.

[0024] When each coil is bent and formed, the following steps need to be performed in sequence: In the hot pressing and bending process, the coil is first placed in the carrier 10, and then the carrier 10 is placed on the first carrier positioning mechanism 21. Then, the heating system 3 heats the coil on the first carrier positioning mechanism 21, and then, the first coil pressing mechanism 22 bends the coil on the first carrier positioning mechanism 21; A transfer process is to quickly transfer the carrier 10 on the first carrier positioning mechanism 21 to the second carrier positioning mechanism 41; In the cold pressing and conforming process, the second coil pressing mechanism 42 presses the coil on the second carrier positioning mechanism 41 until the coil is cooled, and then the carrier 10 on the second carrier positioning mechanism 41 is removed and the coil is removed from the carrier 10 to complete the bending forming of a coil.

[0025] When the carrier 10 on the first carrier positioning mechanism 21 is transferred to the second carrier positioning mechanism 41 for cooling, the first carrier positioning mechanism 21 and the first coil pressing mechanism 22 are both idle, and at this time, another coil can undergo a hot pressing and bending process.

[0026] The first coil pressing mechanism 22 and the second coil pressing mechanism 42 are equivalent to a double workstation. After the first coil pressing mechanism 22 hot presses the previous coil, the previous coil is transferred to the second coil pressing mechanism 42 for pressure-maintaining and cooling. The first coil pressing mechanism 22 can hot press the next coil, thereby improving the coil bending efficiency. The coil is pressure-maintained and cooled in the second coil pressing mechanism 42 to ensure that the shape of the coil will not rebound after cooling, thereby improving the coil bending accuracy.

[0027] In this embodiment, the heating system 3 is a hot air heating system, and the first coil pressing mechanism 22 is further provided with a blowing port 221 , which faces the coil and is connected to the air outlet of the hot air heating system 3 .

[0028] The heating system 3 is a hot air heating system, which heats the coil through the blowing port 221 on the first coil pressing mechanism 22. On the one hand, the blowing port 221 can be close to the coil to improve the heating efficiency of the coil. On the other hand, the heating system 3 and the first coil pressing mechanism 22 will not interfere with each other in space.

[0029] In this embodiment, the air outlet 221 is directed toward the bent position of the coil.

[0030] Since the bent position of the coil needs to be bent and deformed, and other positions do not need to be deformed, the blowing port 221 is set to face the bent position of the coil to heat the coil in a targeted manner, thereby further improving the heating efficiency of the coil. Specifically, the blowing port is located on the side of the coil facing the first coil pressing mechanism and the second coil pressing mechanism.

[0031] In this embodiment, the hot air heating system includes a hot air blowing mechanism 31 and a temperature controller 32. The air outlet of the hot air blowing mechanism 31 is connected to the air outlet 221. The temperature controller 32 is used to adjust the temperature parameters of the hot air blowing mechanism 31, set the temperature range of the hot air blowing mechanism 31, and display the temperature of the hot air blowing mechanism 31 in real time.

[0032] The hot air blowing mechanism 31 is a hot air gun tool that completes various applications by generating high-temperature airflow. The hot air blowing mechanism includes an electric heating element, which is usually a resistance wire or a heating element. When current passes through the electric heating element, it generates heat, causing the temperature of the element to rise. The hot air blowing mechanism also includes a fan or a blower for sucking a large amount of air and sending it to the vicinity of the electric heating element. When the electric heating element is heated, the heat it generates is transferred to the air sent in by the fan. This causes the air to heat up in the process of passing through the electric heating element, forming high-temperature hot air. The front end of the hot air blowing mechanism is usually equipped with a nozzle, and the hot air ejected through the nozzle is directed for specific applications. The working principle of the hot air blowing mechanism is to generate high temperature through the electric heating element, then send air to the heating area through the fan to form high-temperature hot air, and finally use the hot air for specific applications through the nozzle. The hot air heating system includes a hot air blowing mechanism and a thermostat, which can accurately control the heating temperature. The thermostat 32 can set the hot air blowing mechanism 31 to maintain the required operating temperature. This is usually achieved by adjusting the current of the electric heating element.

[0033] In this embodiment, the first coil pressing mechanism 22 includes: Sub-bracket 222; A first pressure head module, which is connected to the sub-bracket 222 and is used to apply pressure to a portion of one side of the coil; The second pressure head module is connected to the sub-bracket 222 and is used to apply pressure to the other side of the coil.

[0034] The first coil pressing mechanism 22 and the second coil pressing mechanism 42 both include a first pressing head module and a second pressing head module. The first pressing head module and the second pressing head module are controlled separately. The first pressing head module first presses and positions the first part of the coil on one side of the bending position, and then the second pressing head module bends the second part of the coil on the other side of the bending position. When the second pressing head module applies pressure to the second part of the coil, the first part of the coil will not rise, ensuring that the coil is bent smoothly. In this embodiment, the first pressure head module includes a first pressure head 223 and a cylinder 224. The first pressure head 223 is used to contact the part on one side of the bent position of the coil. The cylinder 224 is connected to the sub-bracket 222 and is used to drive the first pressure head 223 to approach and move away from the coil.

[0035] The first pressure head 223 is provided with a blowing port 221, and the working principle of the cylinder 224 is to increase the air pressure through the piston, and then the pneumatic transmission converts the pressure of the compressed air into mechanical energy, driving the mechanism to perform linear reciprocating motion, swinging or rotational motion. The cylinder does not require external support facilities such as power supply, and generally only needs to be connected to the air pipeline, so the cost is relatively low. Specifically, the cylinder 224 drives the first pressure head 223 to approach and move away from the coil along the first direction, and the first direction is the vertical direction and perpendicular to the fold of the coil.

[0036] In this embodiment, the first pressure head 223 is elastically connected to the transition bracket 225, the transition bracket 225 is connected to the cylinder 224, and the sub-bracket 222 is also connected to a stroke limiter 226. The height of the stroke limiter 226 along the vertical direction is adjustable, and the upper end of the stroke limiter 226 abuts against the transition bracket 225.

[0037] The first pressure head 223 is connected to the transition bracket 225 through a spring connection device. The first pressure head 223 presses the coil under the action of elastic force, which can compensate for the error caused by the movement of the cylinder without causing damage to the coil. The travel limiter 226 can adjust the pressure of the first pressure head 223 on the coil. For example, when the height of the travel limiter 226 is reduced, the pressure of the first pressure head 223 on the coil increases. When the height of the travel limiter 226 is increased, the pressure of the first pressure head 223 on the coil decreases. Specifically in this embodiment, the above-mentioned travel limiter 226 is a cylinder, and the height of the travel limiter 226 is adjusted by adjusting the extension length of the cylinder piston rod.

[0038] In this embodiment, the second press head module includes a second press head 227, an electric cylinder 228 and an electric rotating table 229. The second press head 227 is used to contact the part on the other side of the bent position of the coil. The electric cylinder 228 is used to drive the second press head 227 to approach and move away from the coil. The electric rotating table 229 is connected to the sub-bracket 222 and is used to adjust the angle between the second press head module and the coil.

[0039] The working principle of the electric cylinder 228 is to convert the rotary motion of the servo motor into linear motion, and to achieve high-precision speed, position and thrust control through closed-loop servo control. The electric cylinder 228 is a modular product that integrates the servo motor and the lead screw, and has the characteristics of precise speed control, precise position control and precise thrust control. The working principle of the electric rotary table 229 mainly relies on the servo motor, which drives the ball screw nut pair through the servo motor, and the nut drives the workbench to move. Specifically, the electric rotary table 229 realizes the rotation of the object through electric drive, integrates core components such as the motor, the reducer, and the controller, and can accurately control the angle, speed and acceleration of the rotation. The motion accuracy of the second press head module is very high, so the coil can be accurately bent. Specifically, the electric cylinder 228 drives the second press head 227 to approach and move away from the coil along the second direction, and the second direction is perpendicular to the fold of the coil. The electric rotary table 229 drives the electric cylinder 228 and the second press head 227 to rotate in a direction parallel to the fold of the coil.

[0040] In this embodiment, the first pressing system 2 also includes a first code scanning mechanism 23, which is used to scan the coils and carriers undergoing hot pressing and upload them to the control system; the second pressing system 4 also includes a second code scanning mechanism 43, which is used to scan the coils and carriers undergoing cold pressing and upload them to the control system.

[0041] Each coil has a unique corresponding QR code, and each carrier 10 also has a unique corresponding QR code. The first scanning mechanism 23 includes a first coil scanning gun 231 and a first carrier scanning gun 232. The first coil scanning gun 231 and the first carrier scanning gun 232 are used to read the QR codes of the hot-pressed coils and the carrier 10. The second scanning mechanism has the same structure as the first scanning mechanism. The second scanning mechanism 43 includes a second coil scanning gun and a second carrier scanning gun. The second coil scanning gun and the second carrier scanning gun are used to read the QR codes of the cold-pressed coils and the carrier 10, thereby recording the hot pressing and cold pressing conditions of each coil, and the hot pressing and cold pressing conditions of the coils can be queried from the control system later, so that the hot pressing and cold pressing data of each coil can be traced.

[0042] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
