Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a flat enameled wire quick bending mechanism. Background Art

[0002] Flat enameled wire is a special type of wire, mainly used in the manufacture of electrical and electronic equipment. Unlike traditional round enameled wire, flat enameled wire has a flat cross-section. This unique geometric shape enables it to provide a larger surface area in a limited space, which is conducive to improving heat dissipation efficiency, enhancing electromagnetic coupling, or adapting to specific coil winding requirements, such as flat motor stator windings. The core of flat enameled wire is a conductive wire made of copper (usually red copper), and its surface is evenly coated with one or more layers of insulating varnish. The insulating varnish can be a high-performance synthetic material such as polyesterimide and polyamideimide. These materials have good electrical insulation properties, heat resistance, mechanical strength and chemical corrosion resistance, ensuring that they can still maintain good insulation in high-temperature working environments to prevent current leakage and short circuits between wires.

[0003] Compared with traditional round enameled wire, the flat shape allows flat enameled wire to be arranged more closely in equipment such as motors and transformers, saving space and helping to achieve miniaturization and lightweight design. Since the flat structure increases the heat dissipation area, the heat generated when the current passes through can be dissipated more effectively, which helps to improve the power density and operating stability of the equipment. In some motor designs, flat enameled wire can better fit the magnetic material, enhance the uniformity and utilization of the air gap magnetic field, and thus improve the efficiency and torque output of the motor.

[0004] Therefore, flat enameled wire is widely used in traditional fields such as motors and transformers. With the advancement of science and technology, its application scope has gradually expanded to advanced manufacturing fields such as wind power, nuclear power, and new energy vehicles. It is specially designed to meet the specific requirements of electrical equipment in terms of space utilization, heat dissipation performance, and magnetic field coupling.

[0005] In the actual use of flat enameled wires, they need to be bent according to different use environments and spaces. For example, for smaller electrical appliances, the enameled wires need to be bent before use. Generally, enameled wires need to be bent manually, but manual bending cannot guarantee the same bending angles in the same batch, resulting in a low pass rate. The use of bending equipment requires higher-precision customized equipment for smaller enameled wires, which will lead to high costs and frequent maintenance. It is not suitable for use with enameled wires of other sizes and has a small scope of application. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Compared with traditional round enameled wire, the flat shape of flat enameled wire allows it to be arranged more closely in motors, transformers and other equipment, saving space and helping to achieve miniaturization and lightweight design. Since the flat structure increases the heat dissipation area, the heat generated when the current passes through can be dissipated more effectively, which helps to improve the power density and operating stability of the equipment. In some motor designs, flat enameled wire can better fit the magnetic material, enhance the uniformity and utilization of the air gap magnetic field, and thus improve the efficiency and torque output of the motor.

[0024] Therefore, flat enameled wire is widely used in traditional fields such as motors and transformers. With the advancement of science and technology, its application scope has gradually expanded to advanced manufacturing fields such as wind power, nuclear power, and new energy vehicles. It is specially designed to meet the specific requirements of electrical equipment in terms of space utilization, heat dissipation performance, magnetic field coupling, etc. Its wide range of industry applications and customized services reflect its important value in the modern electronic manufacturing industry chain.

[0025] In the actual use of flat enameled wires, it is necessary to bend the flat enameled wires according to different use environments and spaces. For example, for smaller electrical appliances, the enameled wires need to be bent before use. Generally, the enameled wires need to be bent manually, but manual bending cannot guarantee the same bending angles in the same batch, which leads to a low pass rate. The use of bending equipment requires customized equipment with higher precision for smaller enameled wires, which will lead to high costs and the need for frequent maintenance. In addition, there is also the problem that it is not suitable for use with enameled wires of other sizes and has a small scope of application. In order to solve the above problems, the present embodiment is provided.

[0026] Reference Figure 1 and Figure 2 For this embodiment 1, Figure 1 This is a schematic diagram of the overall structure of Example 1. Figure 2 It is a schematic cross-sectional view of the overall structure of the present embodiment 1. The present embodiment 1 is a flat enameled wire quick bending mechanism, including a horizontal fixed seat 3, which is a block structure and is slidably installed on the table 1. A punching and bending module 4 is embedded and fixed on the surface of the horizontal fixed seat 3. The table 1 opposite to the punching and bending module 4 is also provided with a lower die seat 2, and a groove is provided in the middle of the lower die seat, and a detachable bending die 14 is provided in the groove; a vertical fixed seat 8 is slidably installed on a vertical fixed plate 13, and the vertical fixed plate is vertically installed on the table 1, and a bending module 7 is embedded on the surface of the vertical fixed seat.

[0027] A horizontal slider 3.1 is integrally fixed to the bottom of the horizontal fixing seat, and the horizontal slider 3.1 matches the horizontal guide rail 3.2 set on the table. The horizontal fixing seat is slidably installed on the horizontal guide rail, and one end of the horizontal fixing seat is provided with a bending module 4, and the other end is connected to the horizontal cylinder 6.

[0028] The bending module 4 is exquisitely designed and can effectively perform precise bending processing on various materials. It is made of high-strength alloy steel material to ensure stability and durability during the bending process. The punch of the bending module 4 can be quickly replaced as needed to adapt to materials of different sizes and shapes. In addition, the bending module is also equipped with an advanced sensing system that can monitor the force and angle during the bending process in real time to ensure that each bending meets the precise requirements.

[0029] The connection with the horizontal cylinder 6 enables the horizontal fixing seat 3 to achieve precise displacement and positioning during the punching and bending process. The horizontal cylinder adopts advanced hydraulic transmission technology, which can quickly and smoothly push the horizontal fixing seat to move along the horizontal guide rail. By accurately controlling the stroke and speed of the horizontal cylinder, the position of the punching and bending module can be accurately controlled, thereby ensuring the accuracy and efficiency of the punching and bending process.

[0030] The lower die base 2 is fixedly installed in the middle of the table, and the groove in the middle of the lower die base corresponds to the punching and bending module. The bending die 14 in the groove is threadedly connected to the lower die base 2, and the end of the bending die close to the punching and bending module is a forming opening 14.1.

[0031] A vertical slider 8.1 and a vertical guide rail 9 are provided between the vertical fixing seat 8 and the vertical fixing plate 13. The vertical slider 8.1 is integrally formed with the vertical fixing seat 8, and the vertical guide rail 9 is integrally formed with the vertical fixing plate 13. The vertical fixing seat is slidably installed on the vertical guide rail, and the vertical fixing plate is fixed on the table top vertically.

[0032] The vertical slider 8.1 slides on the vertical guide rail 9, so that the vertical fixing seat 8 can move freely in the vertical direction. In order to ensure the stability and accuracy of the vertical fixing seat 8, the vertical guide rail adopts high-precision processing technology to ensure its surface finish and straightness. At the same time, a dust cover is also provided between the vertical slider and the vertical guide rail, which can effectively prevent the entry of dust and impurities, and ensure the smooth sliding and accuracy of the vertical fixing seat.

[0033] The vertical fixing plate 13 is responsible for fixing the workpiece to be processed, and its fixing method perpendicular to the table can ensure the stability and accuracy of the workpiece. In order to facilitate user operation, an adjustment handle is also provided on the vertical fixing plate, and the user can manually adjust the position of the vertical fixing plate to meet the processing needs of workpieces of different sizes and shapes.

[0034] The vertical fixing seat 8 is located above the lower die seat, and a bending module 7 is threadedly connected to the surface of the vertical fixing seat 8 away from the vertical fixing plate. The bending module 7 and the punching and bending module 4 are located in the same plane. The vertical fixing seat 8 is connected to the bending lifting cylinder 11 on the side away from the lower die seat 2. During operation, the bending module 7 and the punching and bending module 4 as well as the processing end of the enameled wire need to be located in the same plane, thereby reducing processing deviations. When the device of the embodiment is assembled, the bending module 7 and the punching and bending module 4 need to remain in the same plane, thereby ensuring the accuracy of the device. During processing, it is only necessary to ensure that it is aligned with the punching and bending module to complete the positioning. The installation and positioning of the enameled wire during operation is simple and quick, thereby improving efficiency.

[0035] Two pressure plate lifting cylinders 11 are also fixed on the vertical fixing plates 13 on both sides of the vertical fixing seat 8. The pressure plate lifting cylinder 11 is connected to a push rod at one end close to the table, and a pressure plate 10 is commonly connected to the other end of the push rod. The pressure plate is always located between the vertical fixing seat 8 and the bending die 14, and only moves up and down between the vertical fixing seat 8 and the bending die 14 in a direction perpendicular to the table. The pressure plate is driven by the pressure plate lifting cylinders 11 at both ends. The pressure plate is used to press and fix the enameled wire to avoid excessive local pressure on the enameled wire by the bending module and the punching module during processing, resulting in displacement or offset of the enameled wire, which in turn leads to processing failure or unqualified tolerance. When in use, the enameled wire is placed in the forming port. After placement, the pressure plate lifting cylinder drives the pressure plate to move to the lower module until the pressure plate presses the enameled wire to complete the positioning process before processing.

[0036] The end of the punching and bending module 4 close to the bending die 14 is provided with a cutter head 4.1, and the end of the bending die close to the cutter head is a forming opening 14.1, the cutter head 4.1 and the forming opening 14.1 match each other, the cutter head and the forming opening need to correspond one to one, the protruding part of the cutter head matches the concave part of the forming opening, the enameled wire is located between the cutter head 4.1 and the forming opening 14.1, and is used to punch out the required bending shape, and the shape of the forming opening 14.1 is the bending shape that the enameled wire needs to punch out. In this embodiment, the forming opening 14.1 is the bending die 14 is a part of the present invention, and the bending die is detachably mounted on the lower die base 2, and the punching and bending module is also detachably mounted on the horizontal fixing base. In the present embodiment, the punching and bending module and the horizontal fixing base are fixed with bolts. Therefore, different punching and bending modules and bending dies are customized according to different bending requirements of the enameled wire. To bend the enameled wire with different requirements, only the matching punching and bending modules and bending dies need to be replaced, and there is no need to replace the whole device. Therefore, it has good expansibility and adaptability, and has a fast and convenient adjustment method, and the staff can adjust it without technical threshold.

[0037] A discharge port is provided on one side of the vertical fixed plate close to the surface of the lower die seat, and the discharge port is used to place the enameled wire, and one end of the enameled wire to be processed must be located at the forming port.

[0038] exist Figure 1 and Figure 2 On the basis of the embodiment 1, the main technical solutions such as shape, structure, positional relationship, connection relationship, etc. in the embodiment 1 are further refined and verified according to the actual installation, and the embodiment 2 is obtained. The embodiment 2 is also a flat enameled wire rapid bending mechanism, and the flat enameled wire rapid bending mechanism also includes a power drive system for driving the punching and bending module and the press bending module to work together. The power drive system consists of a servo motor and a set of transmission mechanisms. The servo motor is installed under the table and is connected to the punching and bending module and the press bending module through the transmission mechanism. When the servo motor is started, the transmission mechanism transmits power to the punching and bending module and the press bending module, so that they can perform fast and precise bending operations according to the preset trajectory.

[0039] In addition, in order to ensure the stability and accuracy of the bending process, the mechanism is also equipped with a set of precise measurement and control systems. The measurement and control system consists of displacement sensors, pressure sensors and controllers. The displacement sensors are installed on the punching and bending modules to monitor their positions and speeds in real time; the pressure sensors are installed on the bending molds to detect the pressure changes during the bending process. The measurement and control system transmits these data to the controller, which adjusts the servo motor according to the preset process parameters to ensure the stability and accuracy of the bending process.

[0040] In general, this flat enameled wire rapid bending mechanism realizes rapid and precise bending of flat enameled wire through the coordinated work of the power drive system and the measurement and control system. This mechanism not only improves production efficiency but also ensures product quality.

[0041] The working process of the present embodiment 1 and the embodiment 2 is as follows: during operation, the staff places the enameled wire to be bent flatly in the discharge port and close to the surface of the lower module, and then the staff operates the device of the present embodiment to move the pressing plate downward so that the pressing plate is close to the surface of the lower module and then fixes the enameled wire to avoid uneven force on the enameled wire during bending and causing deviation. After the enameled wire is fixed, one end of the enameled wire to be bent is located at the forming port. At this time, the staff needs to operate the driving bending module to press the end of the enameled wire to be bent downward to the lower part of the punching and bending module. After completion, the staff can operate the punching and bending module to punch the end of the enameled wire to be bent onto the inner wall of the forming port, thus completing the enameled wire bending operation. Finally, the staff operates the driving pressing plate to move in a direction farther than the lower module and thus break away from the fixation with the enameled wire, so as to take out the finished product and complete one processing. For the same product, an electronic control program can be introduced to drive the pressing plate lifting cylinder, the bending lifting cylinder, and the horizontal cylinder, so as to achieve the effect of automated processing.

[0042] Therefore, the device of this embodiment can not only understand and execute these operation steps, but also further optimize the workflow and improve production efficiency. For example, the speed and force of the pressing plate can be intelligently adjusted according to historical data and real-time feedback to ensure that the enameled wire is evenly stressed during the bending process and avoid offset. In addition, the device of this embodiment can also automatically adjust the parameters of the punching and bending module according to product specifications and requirements to achieve precise bending angles and lengths.

[0043] In terms of automated processing, the device of this embodiment can be seamlessly connected with the electronic control program to achieve fully automated operation. Through the preset processing parameters and process flow, the device of this embodiment can automatically drive the actuators such as the lifting cylinder and the horizontal cylinder to complete a series of complex bending and punching operations. This not only greatly improves production efficiency, but also reduces labor costs and improves the competitiveness of enterprises.

[0044] In addition, the device of this embodiment also has powerful data analysis and learning capabilities. By analyzing and learning the data in the production process in real time, the device of this embodiment can continuously optimize the process parameters and operation process, and improve product quality and production efficiency.

[0045] The beneficial effects of Example 1 and Example 2 are as follows:

[0046] The main structure of this embodiment is composed of four parts, namely, a punching and bending module, a press bending module, a pressing plate, and a bending die, and a corresponding driving cylinder. The overall structure is simple and easy to maintain. The modular design facilitates assembly and disassembly and movement. The device of this embodiment is composed of a processing mechanism consisting of a punching and bending module, a press bending module, and a pressing plate. The operation is simple, and the operator does not need technical thresholds, which saves labor costs. In addition, this embodiment can introduce an electronic control program to realize automated batch processing, and then divide the device of this embodiment into manual and automatic modes, which can be flexibly adjusted according to the use environment. This embodiment has strong adaptability and a wide range of applications, and can be flexibly adjusted according to different environments.

[0047] In the device of this embodiment, both the punching and bending module and the press bending module are provided with a slide rail mechanism, which can flexibly adjust the relative position, so as to reserve more different types of enameled wires, thereby making the device of this embodiment more adaptable and applicable. The blade head of the punching and bending module and the forming mouth of the bending die match each other and are both detachably installed, and can be replaced and adjusted accordingly according to different bending requirements. Compared with precise fully automated devices, the detachable adjustment has lower cost, wider application range and more convenient maintenance.

[0048] In addition, a pressing plate mechanism is introduced in the device of this embodiment, which can position and fix the enameled wire to be bent before the bending process, thereby avoiding the problem of relative movement of the enameled wire and subsequent processing deviation during the punching and bending process. This mechanism has a simple structure, consisting only of a pressing plate and two cylinders, and has good positioning and fixing effects, thereby improving the processing accuracy and reliability of the device of this embodiment.
