The telescopic end of the traction cylinder 42 is fixed on the adapter block 49.

[0041] Working principle:

[0042] Loosen the knob screw 63 and adjust the inclination angle of the swing plate 65 in the feed assembly 6, and tighten the knob screw 63 after ensuring that the inclination angles of the swing plates 65 in the two feed assemblies 6 are the same; place multiple steering brackets 8 in sequence along the length direction of the loading strip 61 on the top of each loading strip 61 and between the baffles 64 in the two feed assemblies 6, and make the raised portion 81 on each steering bracket 8 face upward. After that, each steering bracket 8 will automatically slide to the lower right along the top of the loading strip 61 with the help of the inclination of each loading strip 61.

[0043] The telescopic end of the traction cylinder 42 in the driving partition assembly 4 contracts inward to drive the guide plate 45 to move to the right, and then the traction groove 451 and the guide column 46 are cooperated to drive the guide column 46 to move to the left along the traction groove 451, so as to drive the block 44 to move vertically downward with the help of the slope of the traction groove 451, until the top right edge of the block 44 is lower than the bottom of the rightmost steering bracket 8, so that the rightmost steering bracket 8 can automatically slide to the right under the push of each subsequent steering bracket 8, until the bottom right edge of the rightmost steering bracket 8 abuts against the left edge of the fixed block 43 to stop sliding, at this time, the rightmost steering bracket 8 is located above the block 44.

[0044] The telescopic end of the driving traction cylinder 42 is extended outward to drive the stopper 44 to move upward in the same way, thereby pushing the rightmost steering bracket 8 to move upward. When the right edge of the second guide slope 441 is flush with the left edge of the first guide slope 431, the steering bracket 8 located on the top of the stopper 44 will automatically slide onto the first guide slope 431 with the help of the second guide slope 441, and continue to automatically slide to the top of the seat plate 210 and the support seat 211 with the help of the slope of the first guide slope 431; before this, it is also necessary to drive the telescopic end of the positioning cylinder 32 in the positioning assembly 3 to extend outward to push the V-shaped The other end of the positioning strip 33 swings to the right until the other end of the V-shaped positioning strip 33 is located between the seat plate 210 and the support seat 211. When the bottom right edge of the steering bracket 8 that slides to the top of the seat plate 210 and the support seat 211 contacts the other end of the V-shaped positioning strip 33, the steering bracket 8 stops moving and reaches the specified position, and the rear side of the steering bracket 8 is attached to the front outer wall of the limit strip 212; when the steering bracket 8 leaves the top of the stop block 44, the telescopic end of the traction cylinder 42 can be driven to retract inward to drive the stop block 44 to move downward in the same way, so that the next steering bracket 8 is blocked by the fixed block 43 again and cannot continue to feed.

[0045] Afterwards, the telescopic end of the stamping cylinder 23 in the stamping unit 2 is driven to extend outward to drive the tool holder 25 and the two punching tools to move downward with the help of the pressure plate 24, so that the pressure strips 26 in the two punching tools are both attached to the top of the steering bracket 8 and are respectively located on the left and right sides of the raised part 81. When the pressure plate 24 continues to move downward, the buffer bolt 28 in each buffer unit will move upward and compress the buffer spring 29, and finally the two pressure strips 26 will be flexibly pressed on the top of the steering bracket 8; during this process, the tool holder 25 will drive each punching column 27 to continue to move downward, and then two rows of through holes 82 will be punched out at the top of the steering bracket 8 at the same time.

[0046] After the stamping is completed, the telescopic end of the stamping cylinder 23 is driven to retract inward to drive the two punching tools to move upward until the bottom of each pressure strip 26 is higher than the raised part 81, and then the telescopic end of the positioning cylinder 32 in the positioning assembly 3 is driven to retract inward to drive the other end of the V-shaped positioning strip 33 to swing to the left in the same way until the other end of the V-shaped positioning strip 33 moves to its original position; then the telescopic end of the traction cylinder 42 in the partition assembly 4 is driven to extend outward to drive the stopper 44 to move vertically downward in the same way, so that the next steering bracket 8 slides to the top of the seat plate 210 and the support seat 211 and pushes the previous steering bracket 8 that has completed stamping to the top of the receiving plate 7. The steering bracket 8 located on the receiving plate 7 will slide to the supporting plate 71 with the help of the inclination of the receiving plate 7. Finally, the steering bracket 8 can be manually removed, and the blocking edge 72 can prevent the steering bracket 8 from slipping.

[0047] The utility model realizes the automatic feeding and discharging of the steering bracket 8 to ensure the continuity of processing, without manual operation, thereby simplifying the operating steps to improve the processing efficiency, thereby achieving the effect of saving time and labor, and avoiding the operator's close contact with the stamping equipment to eliminate safety hazards; in addition, it also has automatic limiting and flexible positioning functions to ensure processing accuracy.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein with equivalents.
