[0023] For the stamping processing of micro metal parts, the raw materials generally used are coils of narrow metal strips. In order to improve the processing efficiency, a reel conveyor rack is generally provided to allow the narrow metal strips to automatically enter the punch press to be punched to form workpieces. However, in the related art, it is necessary to manually guide the narrow metal strips to move into the processing position of the punch press for stamping and forming, which is inefficient and does not meet the use requirements.
[0024] For this purpose, refer to Figure 1 and Figure 2, which is a micro metal part stamping and forming device proposed by the utility model, includes a frame 100 and a feeding mechanism. The frame 100 is provided with a stamping assembly 110 and a collecting trough 120. The stamping assembly 110 is used for pressing and forming micro metal parts. The side wall of the frame 100 is slidably provided with a pushing rod 130 for pushing the micro metal parts into the collecting trough 120. The feeding mechanism is connected to the frame 100 and is located above the collecting trough 120. The feeding mechanism includes a bracket 200 and a rotating wheel 300 connected to the bracket 200. The rotating wheel 300 can rotate on the bracket 200. A limiting assembly 400 is provided on the side wall of the rotating wheel 300. The limiting assembly 400 includes two adjacent long rods 410. A limiting groove 420 is formed between the long rods 410 to limit the falling of the metal narrow strip. The rotating wheel 300 is provided with a slot along the circumferential side wall. The end of the long rod 410 is inserted into the slot. The side wall of the long rod 410 is provided with an elastic tension sleeve. The tension sleeve is connected to the slot by interference fit to fix the long rod 410 and the rotating wheel 300. It can be understood that after the worker starts the device, the end of the metal strip coil on the feeding mechanism is inserted into the stamping assembly 110, the stamping device is pressed down to form micro metal parts, and then the stamping assembly 110 is lifted, and the push rod 130 pushes the formed micro metal parts into the collecting trough 120 to complete the unloading. The feeding mechanism is driven by the motor to rotate and drive the metal strip coil to rotate. The rotating wheel 300 drives the coil to continuously release the metal strip, and the two side edges of the metal strip can abut the side wall of the long rod 410. The entire metal strip coil is limited by the limit groove 420. The limit assembly 400 limits the moving direction of the metal strip to prevent deviation from smoothly entering the punch press. No manual monitoring and adjustment are required, thereby improving production efficiency.
[0025] Reference Figure 1 and Figure 2 The collecting trough 120 is an arc-shaped trough to guide the micro metal parts into the bottom of the collecting trough 120. Furthermore, a visual inspection device 140 is provided directly above the collecting trough 120 to inspect the outer surface of the micro metal parts, thereby quickly inspecting the processed micro metal parts, further improving the processing efficiency.
[0026] Reference Figure 1 It should be noted that the frame 100 is also provided with a limit bayonet 150 for the metal strip to pass through, so as to prevent the metal strip from being transported too fast and causing local deformation, and then being driven by its own elastic force to separate from the stamping assembly 110. The limit bayonet 150 can limit and guide the moving direction of the metal strip.
[0027] Reference Figure 1 and Figure 2There are four limit assemblies 400, which are equidistant and evenly arranged along the circumference of the rotating wheel 300 to enhance the limiting effect on the metal narrow strip coil, further prevent the metal narrow strip from being deviated in the conveying direction and unable to smoothly enter the stamping assembly 110, thereby improving processing efficiency and product quality.
[0028] Furthermore, in some embodiments, two rotating wheels 300 are provided, and the two rotating wheels 300 are respectively arranged on opposite sides of the same position of the bracket 200, so that before the coil of material on one side is used up, the worker can complete the loading of the coil of material and the installation of the limiting component 400 on the rotating wheel 300 on the other side in advance, thereby preventing the need to temporarily shut down the entire device due to filling the coil of material, thereby further improving the processing efficiency.
[0029] According to some embodiments of the utility model, a guide inclined plate 411 is provided at the end of the long rod 410 away from the rotating wheel 300, and the guide inclined plate 411 is inclined toward the outer side away from the bracket 200, so as to increase the contact area between the metal narrow strip and the entire limiting assembly 400 to ensure the guiding effect. Optionally, the inclination angle of the guide inclined plate 411 is 10° to 15°.
[0030] Reference Figure 2 It can be understood that the long rods 410 on both sides of the limiting groove 420 are arranged in a staggered manner. This increases the contact area between the metal narrow strip and the long rod 410 when the metal narrow strip is in the limiting groove 420, thereby enhancing the limiting and guiding effect of the limiting assembly 400 on the metal narrow strip.
[0031] Reference Figure 1 The bracket 200 includes a crossbar 210 and a vertical bar 220. The vertical bar 220 and the crossbar 210 are vertically connected to each other. The rotating wheel 300 is arranged at the end of the vertical bar 220 away from the crossbar 210. The crossbar 210 is used to connect an external mechanism. The bracket 200 is used to fix the frame 100. The rotating wheel 300200 is arranged at the end of the bracket 200100, and there is a certain clearance between the bracket 200100 and the frame 100 to ensure that the metal strip can be unrolled and transported smoothly.
[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
