[0013] Example

[0014] refer to Figures 1 to 4 This embodiment describes a stamping device for producing table and chair legs, comprising a base 1. A frame 2 is fixedly connected to the top of the base 1, and a cylinder 3 is fixedly connected to the top of the frame 2. An upper die 4 is fixedly connected to the output end of the cylinder 3. An adjustment component 7 is provided on one side of the base 1, and a rotary table 5 is rotatably connected to the base 1 via the adjustment component 7. One side of the frame 2 passes through the rotary table 5, and lower dies 6 are fixedly connected to both sides of the top of the rotary table 5. It should be noted that the lower die 6 is equipped with a pushing device, which can be an electric push rod, push plate, or other structure, to achieve the purpose of unloading the stamped material. This is a common structure in the prior art and is not an innovation of this solution, so it will not be elaborated further here. The upper mold 4 and the lower mold 6 are adapted to each other. Sliding legs 8 are fixedly connected to both sides of the bottom end of the rotary table 5. A marking block 11 is fixedly connected to one side of the sliding leg 8. An infrared sensor 12 is provided on the side of the frame 2 away from the adjustment component 7. A positioning mechanism 13 is provided on one side of the infrared sensor 12. During operation, the adjustment component 7 drives the rotary table 5 to rotate, so that the lower mold 6 is moved directly below the upper mold 4. The positioning mechanism 13 fixes the rotary table 5. The cylinder 3 drives the upper mold 4 to press down to complete the stamping. After that, the positioning mechanism 13 is released, and the adjustment component 7 drives the rotary table 5 to rotate, so that the other lower mold 6 is moved below the upper mold 4. At the same time, the operator can pick up and put down the material in the support leg of the upper lower mold 6.

[0015] refer to Figure 1 The adjustment component 7 includes a fixed plate 71, which is fixedly connected to one side of the machine base 1. A first motor 72 is fixedly connected to the top of the fixed plate 71, and a transmission gear 73 is fixedly connected to the output end of the first motor 72. A transmission gear ring 74 is fixedly connected to the periphery of the rotary table 5, and the transmission gear 73 meshes with the transmission gear ring 74. By setting the adjustment component 7, when it is necessary to rotate the rotary table 5 to adjust the position of the lower mold 6, the first motor 72 is started, the transmission gear 73 rotates, thereby driving the transmission gear ring 74 and the rotary table 5 to rotate together, so as to adjust the position of the lower mold 6. The position switching is convenient and quick, and more accurate and labor-saving than manual adjustment.

[0016] refer to Figure 4 The bottom end of the sliding leg 8 is equipped with a pulley 9, and the top end of the base 1 is provided with an annular groove 10. The pulley 9 is slidably connected inside the annular groove 10. When the rotating table 5 rotates, the pulley 9 slides in the annular groove 10, which makes the rotating table 5 rotate smoothly, reduces the friction when the rotating table 5 rotates, and makes the rotation smoother and less strenuous.

[0017] refer to Figure 2-3 The positioning mechanism 13 includes a positioning frame 131, which is fixedly connected to both sides of the sliding leg 8. A positioning rod 132 is inserted into the interior of the positioning frame 131. A sliding plate 133 is fixedly connected to one side of the positioning rod 132. A second motor 134 is fixedly connected to one side of the base 1. A screw 135 is fixedly connected to the output end of the second motor 134. The sliding plate 133 is threaded onto the outer surface of the screw 135. A mounting bracket 137 is fixedly connected to one side of the frame 2. One side of the screw 135 is rotatably connected to the mounting bracket 137. The mounting bracket 137 is located on both sides of the screw 135. All are fixedly connected to slide rods 136, and the slide plate 133 is slidably connected to the slide rods 136. By setting a positioning mechanism 13, when the rotary table 5 rotates to the designated position, the infrared sensor 12 senses the marker block 11, and the second motor 134 drives the screw 135 to rotate. When the screw 135 rotates, the slide plate 133 will move along the screw 135 and the slide rods 136 on both sides, driving the positioning rod 132 to move, so that the positioning rod 132 is inserted into the positioning frame 131 to fix the rotary table 5. After the stamping is completed, the motor reverses, the positioning rod 132 is pulled out, and the rotary table 5 can continue to rotate, fixing the rotary table 5 so that it will not shake during stamping and ensuring stamping accuracy.

[0018] refer to Figure 1 The rotating table 5 has a through hole 14 in the middle, and one side of the frame 2 passes through the through hole 14. By setting the through hole 14, since the frame 2 passes through the through hole 14, the rotation of the rotating table 5 is not affected when the rotating table 5 rotates.

[0019] Operating principle and advantages: The first motor 72 drives the transmission gear 73 to rotate. The transmission gear 73 meshes with the transmission gear ring 74 on the periphery of the rotary table 5, thereby driving the rotary table 5 to rotate. During the rotation of the rotary table 5, the pulley 9 on the bottom sliding leg 8 slides in the annular groove 10 at the top of the machine base 1, ensuring the smooth movement of the rotary table 5. When the rotary table 5 moves the lower mold 6 directly below the upper mold 4, the marker block 11 on one side of the sliding leg 8 is detected by the infrared sensor 12 on the frame 2. The infrared sensor 12 then transmits a signal to the central control system, and the positioning mechanism 13 starts to operate. The second motor 134 drives the screw 135 to rotate. Since the sliding plate 133 is threadedly connected to the screw 135 and slidably connected to the sliding rods 136 on both sides, the sliding plate 133 drives the positioning rod 132 to move towards the positioning frame 131. Finally, the positioning rod 132 inserts into the positioning grooves on both sides of the sliding leg 8. Within the positioning frame 131, the rotary table 5 is firmly fixed. Then, the cylinder 3 at the top of the frame 2 drives the upper mold 4 to move downward, cooperating with the lower mold 6 to complete the stamping and forming of the plastic blank. After stamping, the cylinder 3 drives the upper mold 4 to reset, the second motor 134 in the positioning mechanism 13 reverses, the screw 135 drives the slide plate 133 and the positioning rod 132 to retract, the positioning rod 132 is pulled out from the positioning frame 131, the rotary table 5 is released from fixation, and then the adjusting component 7 drives the rotary table 5 to rotate again, rotating the lower mold 6, which has a new blank already placed, to directly below the upper mold 4, repeating the above positioning and stamping process. At the same time, the operator can operate the lower mold 6 that has completed the stamping, push out the formed support leg, and then put in a new plastic blank to prepare for the next stamping, avoiding the waiting time of traditional single mold stamping and greatly improving production efficiency.
