Embodiment 1
[0039] A flat punching die for a leisure chair support in this embodiment includes an upper die 1, a lower die 2, a base 3, a punching needle 5 and a positioning block 10, and also includes a flattening guide mechanism 4 and an extrusion flattening block 7 , return spring 8 and rotating shaft 9; wherein: the upper die 1 is a block structure, the punching pin 5 is fixed at the center of the bottom surface of the upper die 1, and there are two punching flat guiding mechanisms 4, which are symmetrically fixed on the punching pins 5 respectively The left and right sides of the lower mold 2 are also block structures, which are vertically fixed on the upper surface of the base 3; The center, the position directly below the punching needle 5, the vertical circular hole corresponds to the punching needle 5; the extrusion punching flat block 7 is two, obtuse triangle structure, symmetrical on both sides of the positioning block 10 and showing the largest side facing Set outside, pass t...
Embodiment 2
[0049] Such as figure 1 As shown, a flat punching die for a leisure chair support of this embodiment has the same basic structure as that of Embodiment 1, the difference is that the positioning block 10 is detachably fixed directly above the positioning block 10 and has a through vertical The guide block 6 of the circular hole, the vertical circular hole of the guide block 6 and the vertical circular hole of the positioning block 10 have the same diameter and remain on the same vertical center line as the punching needle 5; the left outer side of the positioning block 10 is extruded and flattened The front side of the block 7 is provided with a positioning rod 11 fixed on the base 3; the two opposite inner lower end slopes of the two extruded and flattened blocks 7 are detachably and fixedly connected with a shaping block 12 near the bottom corner. ; The flattening guide mechanism 4 is a flattening adjusting screw; the flattening extrusion block 7 is in the shape of a right tr...
Embodiment 3
[0059] Such as figure 2 As shown, a flat punching die for a leisure chair support in this embodiment has the same basic structure as that in Embodiment 2, the difference is that the bottom end surface of the flattening adjustment screw is an inclined plane, and the slope is the same as that of the extruded flattening block 7 The slope at the upper end is the same; the punching needle 5 is detachably fixed; a foot controller is added to control the movement of the upper die 1 .
[0060] A method for using the flattening punching die for the leisure chair support of the present embodiment, the steps are:
[0061] A: Connect the upper mold 1 with the hydraulic mechanism;
[0062] B: Put the front end of the leisure chair bracket on the positioning block 10, and use the positioning rod 11 to position and straighten it;
[0063] C: Press the pedal controller with your foot to start the hydraulic mechanism, and the upper mold 1 moves downward;
[0064] D: When the punching needl...
