[0019] And when the worker puts the workpiece clamped by the clamp into the lower die seat 2, through the lower die seat 2 that can slide, the lower die seat 2 can be away from the upper die head 3, so as to avoid the worker from approaching the upper die head 3 when feeding, thereby preventing being pressed by the upper die head 3, so as to improve the safety of feeding.

[0020] The sliding structure of the lower die seat 2 is that two sliding rails 14 are arranged in parallel in the displacement slot 101, a second lead screw 13 is arranged between the two sliding rails 14, the second lead screw 13 is rotatably connected to the bases on both sides through bearing seats, a corresponding motor is connected to one side of the second lead screw 13 through a shaft coupling, a connecting seat is sleeved on the outer periphery of the second lead screw 13, and a sliding block matched with the sliding rail 14 is fixed to the bottom of the connecting seat. The lower die seat 2 is fixed on the connecting seat, so that the connecting seat sleeved on the outer periphery of the second lead screw 13 and matched with the second lead screw 13 is moved along the direction of the second lead screw 13 under the guiding action of the sliding block and the sliding rail 14, so that the lower die seat 2 moves away from or approaches the upper die head 3. The machine table 1 is provided with an infrared sensor in the direction in which the lower die seat 2 approaches the upper die head 3, so that the corresponding motor is stopped through the PLC controller when the lower die seat 2 moves to the detection range of the infrared sensor, and the second lead screw 13 is stopped. By adjusting the detection accuracy of the infrared sensor, it can be ensured that the lower die seat 2 can be relative to the upper die head 3 after the lower die seat 2 moves towards the upper die seat.

[0021] In the embodiment, one side of the machine table 1 is provided with a mounting plate 5, the mounting plate 5 is provided with a lifting mechanism, the lifting mechanism includes two vertical guide rods 12 and a first lead screw 10 located between the two guide rods 12, the first lead screw 10 is rotatably connected with the mounting plate 5 through a bearing seat and is driven to rotate by a corresponding motor.
