The first motor 111 is fixed in the base 104, and the output end of the first motor 111 is fixed to the screw 109; the lower mold 110 is arranged on the base 104, and the shaping component 103 includes a stamping cylinder 112, a stamping head 113, an upper mold 114 and a fixing bolt 115. The stamping cylinder 112 is fixed on the support frame 105, and the stamping head 113 is arranged on the output end of the stamping cylinder 112. The upper mold 114 is connected to the stamping head 113 through the fixing bolt 115.

[0021] In this embodiment, the support assembly 101 is composed of a sturdy and durable base 104 and a support frame 105. The base 104 provides a stable installation platform to ensure the stability of the entire device during operation. The support frame 105 is vertically fixed to the top of the base 104, which not only enhances the overall rigidity of the device, but also provides the necessary height support for the subsequent shaping assembly 103. The positioning assembly 102 includes a positioning rod 106, three sliding blocks 107, an extrusion ring 108, an adjustment screw 109, a lower mold 110 and a first motor 111. The positioning rod 106 is firmly connected to the base 104, and three precision-cut slide grooves are provided on one side thereof, which provide a basis for the precise guidance of the sliding block 107. The three sliding blocks 107 are flexibly embedded in these slides and can move smoothly along the inclined groove on the positioning rod 106. The extrusion ring 108 cooperates with the positioning rod 106 through a sliding connection, and its position can be adjusted as needed, and is connected to the first motor 111 through a screw 109. The rotation of the motor drives the screw 109 to rotate, and then the extrusion ring 108 can be controlled to move up and down to control the position of the three sliding blocks 107, so as to adapt to commutators of different sizes. The lower mold 110 is installed on the base 104, and cooperates with the sliding block 107 to provide initial positioning and clamping for the commutator. The shaping component 103 is directly responsible for the bending hook shaping of the copper bar. The component consists of a stamping cylinder 112, a stamping head 113, an upper mold 114 and a fixing bolt 115. The stamping cylinder 112 is firmly mounted on the support frame 105, and the stamping head 113 is driven by compressed air or hydraulic power to perform high-speed and accurate downward impact. The punch head 113 is installed at the output end of the cylinder to ensure efficient transmission of force. The upper mold 114 is tightly connected to the punch head 113 through a high-strength fixing bolt 115, and together they form a closed molding space, applying precise punching force to the copper bar placed therein to complete the shaping of the hook. The upper mold 114 and the lower mold 110 can be replaced according to the size of the commutator, so that the device can be applied to commutators of different sizes, making the work more convenient.

[0022] The support assembly 101 further includes a reinforcing rod 116, which is fixedly connected to the support frame 105 and the base 104 and is located between the support frame 105 and the base 104. The reinforcing rod 116 is not only tightly fixed to the support frame 105, but also has a stable connection with the base 104, and is cleverly inserted between the support frame 105 and the base 104. This design significantly improves the stability and pressure resistance of the overall structure, and ensures the durability and shape of the device even in the face of high-intensity operations.

[0023] The support assembly 101 further includes a vibration-damping pad 117, which is fixedly connected to the base 104 and is located at the bottom of the base 104. In order to improve the working stability of the equipment and reduce the vibration transmission during the operation, the vibration-damping pad 117 is added to the support assembly 101. These vibration-damping pads 117 are firmly fixed to the bottom of the base 104, effectively absorbing and dispersing the vibration generated during the operation of the equipment, thereby protecting the precision parts of the device, reducing noise, and improving the comfort of the working environment of the operator.

[0024] The positioning assembly 102 further includes a support spring 118, which is disposed between the three sliding blocks 107 and the base 104. The support spring 118 is disposed between each sliding block 107 and the base 104, which not only provides the necessary resilience for the smooth sliding of the sliding block 107, but also ensures the response speed and accuracy of the positioning system under various working conditions.

[0025] The positioning assembly 102 also includes a push block 119 and a lifting plate 120. The push block 119 is slidably disposed in the base 104 and is threadedly connected to the screw 109. The lifting plate 120 is disposed above the push block 119 and is used to push out the commutator after shaping. The positioning assembly 102 also introduces a combination mechanism of a push block 119 and a lifting plate 120. The push block 119 is designed as a slidable structure and is connected to the screw 109 through a thread. When the shaping process is completed, the push block 119 is driven to move upward by the rotation of the screw 109, and then the lifting plate 120 pushes out the finished commutator gently and accurately, which greatly simplifies the operation process and improves production efficiency.

[0026] The shaping assembly 103 further includes a return spring 121, which is disposed between the stamping cylinder 112 and the stamping head 113. The spring is carefully arranged between the stamping cylinder 112 and the stamping head 113, and immediately takes effect after each stamping action is completed, quickly restoring the stamping head 113 to its initial position, ensuring the efficiency and rhythm of continuous operation, avoiding unnecessary waiting time, and improving the continuity and production efficiency of the overall operation.

[0027] The usage process of this device is as follows:

[0028] During operation, the commutator to be processed is placed on the positioning rod 106 on the base 104, and then the first motor 111 is started to drive the screw 109 to rotate to drive the extrusion ring 108 to move downward so that the extrusion ring 108 gradually slides out of the groove to contact and fix with the inner wall of the commutator, and then the stamping cylinder 112 is started to drive the punching head 113 to move downward, so that the upper mold 114 and the lower mold 110 are combined to shape the commutator. After the shaping is completed, the punching head 113 returns to its original position under the action of the reset spring 121, and then the first motor 111 is started to drive the extrusion ring 108 and the push block 119 to move upward, so that the lifting plate 120 can lift the commutator.

[0029] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope covered by the utility model.
