[0038] Working principle:

[0039] The tubular mower handle is placed horizontally and moved to the left of the backrest plate 21, and then the right end of the mower handle is inserted between the left arc-shaped buckle plate 22 and the arc-shaped positioning groove 211, and continues to move to the right until the right end of the mower handle passes through the right arc-shaped buckle plate 22 and the arc-shaped positioning groove 211 and extends to the right of the backrest plate 21.

[0040] According to the processing needs, the manual sliding table 41 in the positioning mechanism 4 is controlled to drive the baffle 43 to move left or right by the rotary cylinder 42. When moving, the scale rod 44 is movably embedded in the limiting notch 431, and the distance between the left outer wall of the baffle 43 and the right outer wall of the backrest plate 21 can be adjusted by the scale rod 44. When the right end of the mower handle abuts against the left outer wall of the baffle 43, the distance of the right end of the mower handle extending to the right of the backrest plate 21 is determined, and the first stamping position located on the front side of the mower handle is determined.

[0041] If the angle of stamping needs to be changed, the knob screw 35 can be loosened first, then the extension part 342 is held by hand and swung left or right, and then the angle between the stamping cylinder 31 and the mower handle is changed by the rotatable connection relationship between the carrier plate 34 and the bottom plate 1. When the carrier plate 34 swings, the threaded end of the knob screw 35 will slide along the direction of the arc-shaped limiting slot 101. When reaching the specified angle, the knob screw 35 can be tightened. During operation, the operator's line of sight can view the value on the arc-shaped scale area 102 through the arc-shaped observation hole 341.

[0042] Then the electric sliding table 51 in the feeding mechanism 5 is controlled to drive the sliding block 52 to move left until the left outer wall of the pressing block 54 abuts against the left buffer block 58, and then the extension end of the positioning cylinder 23 is driven to extend outward to drive the pressing block 54 to move backward, and then the mower handle is pressed by the pressing block 54. At this time, the arc-shaped pressing groove 541 is tightly attached to the front outer wall of the mower handle to increase the friction force, so that the mower handle cannot move left and right. Finally, the extension end of the stamping cylinder 31 is driven to extend outward to drive the stamping column 32 to move in the direction of the mower handle at the predetermined angle, and then the first stamping on the mower handle is completed.

[0043] After the first stamping is completed, the telescopic end of the stamping cylinder 31 is first driven to retract inward to reverse reset the stamping column 32, and then the rotating end of the rotating cylinder 42 is driven to rotate away from the scale rod 44, thereby driving the baffle 43 to move away from the rear end of the lawn mower handle; then the electric sliding table 51 in the feeding mechanism 5 is controlled to drive the sliding block 52 to move to the right, and in this process, each roller 24 will roll along the rear side outer wall of the lawn mower handle, thereby ensuring the smoothness of the lawn mower handle when moving to the right, and ensuring that the lawn mower handle will not move up and down under the action of the two rows of rollers 24.

[0044] When the right side outer wall of the pressing block 54 abuts against the right side buffer block 58, the second stamping position of the front side of the lawn mower handle is determined, and then the telescopic end of the stamping cylinder 31 is driven to extend outward to drive the stamping column 32 to move in the direction of the lawn mower handle at a predetermined angle, thereby completing the second stamping on the lawn mower handle.

[0045] After the second stamping is completed, the telescopic end of the stamping cylinder 31 is first driven to retract inward to reverse reset the stamping column 32, and then the telescopic end of the positioning cylinder 23 is driven to retract inward to drive the pressing block 54 away from the lawn mower handle, and finally the stamped lawn mower handle is pulled out to the right.

[0046] The utility model can adjust the relative angle between the stamping column 32 and the lawn mower handle as required, and quickly and accurately determine the extension length of the right end of the lawn mower handle with the help of the positioning mechanism 4, thereby expanding the application range and improving the positioning accuracy to effectively reduce the processing error; in addition, the feeding mechanism 5 can also be used to realize automatic feeding of the lawn mower handle and quickly and accurately determine the second stamping position, thereby saving a lot of time to effectively improve the processing efficiency.

[0047] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
