[0028] The above-mentioned setting of the chip inlet 6 allows the chips generated by the steel back during precision hydraulic pressure to enter the chip storage hole 11 through the chip inlet 6 for storage, and the chip guard plate 7 arranged around the chip inlet 6 can prevent the chips from flying out. When the chips enter the chip storage hole 11, the chip pusher 14 can push the chips toward the chip outlet 8. When the chips enter the chip outlet 8, they will be driven and discharged by the chip conveyor 12 installed in the chip outlet 8, thereby preventing the chips from accumulating in the chip outlet 8 and causing the chip outlet 8 to be blocked.

[0029] In this embodiment, the chip conveyor 12 includes a motor 21 , a connecting shaft 22 , and a chip conveying fan 23 . The motor 21 is fixed in the base 1 . The motor 21 is connected to the connecting shaft 22 . The chip conveying fan 23 is fixed to the connecting shaft 22 .

[0030] The motor 21 is started to drive the connecting shaft 22 to rotate, and the chip removal fan 23 fixed on the connecting shaft 22 can push the chips in the chip outlet 8 and bring them out of the chip outlet 8.

[0031] In this embodiment, the chip ejector 14 includes a movable rod 41, a tooth block 42, a linkage rod 43, a tooth groove 44, a spring 45, and a push plate 46. The other end of the conveyor belt 13 is matched with a movable rod 41 movable in the base 1, and a tooth block 42 is fixed to one end of the movable rod 41. A linkage rod 43 movable in the base 1 is provided under the tooth block 42, and a tooth groove 44 matched with the tooth block 42 is provided on the linkage rod 43. A push plate 46 is fixed to one end of the linkage rod 43, and a spring 45 is fixed between the push plate 46 and the chip storage hole 11.

[0032] The tooth block 42 mentioned above surrounds half of the circumference of the movable rod 41, and the tooth block 42 cooperates with the tooth groove 44. When the motor 21 is started, the connecting shaft 22 drives the conveyor belt 13, and the other end of the conveyor belt 13 is matched with the movable rod 41. At this time, the movable rod 41 starts to rotate, and the tooth block 42 is fixed on the movable rod 41. The tooth block 42 rotates with the rotation of the movable rod 41, and the matching linkage rod 43 starts to translate toward the direction of the chip storage hole 11, driving the push plate 46 to translate. When the movable rod 41 rotates to a place where there is no tooth block 42, due to the spring 45 fixed on the push plate 46, the push plate 46 is pulled back, driving the linkage rod 43 to be pulled back together, and when the movable rod 41 rotates to the time when the tooth block 42 cooperates with the linkage rod 43, the push plate 46 is pushed out again, and this is repeated.

[0033] In this embodiment, the chip guard plate 7 includes an air pump 71, an air pipe 72, a baffle 74, a slot 73, and an air outlet 75.

The connection blocks 62 are fixed on the base 1 , the placement modules 61 are fixed between the connection blocks 62 , and the chip inlet block 63 is fixed on the connection blocks 62 .

[0036] As described above, by configuring the chip entry block 63 , when chips fall onto the chip entry block 63 , the chips will enter the chip storage hole 11 along the inclined surface of the chip entry block 63 .

[0037] Working principle:

[0038] By starting the motor 21, the connecting shaft 22 is driven to rotate, and the chip removal fan 23 fixed on the connecting shaft 22 can push the chips in the chip outlet 8 and bring them out of the chip outlet 8. When the motor 21 is started, the connecting shaft 22 drives the conveyor belt 13, and the other end of the conveyor belt 13 is equipped with a moving rod 41. At this time, the moving rod 41 begins to rotate, and a tooth block 42 is fixed on the moving rod 41. The tooth block 42 rotates with the rotation of the moving rod 41, and the coordinated linkage rod 43 begins to translate toward the direction of the chip storage hole 11, driving the push plate 46 to translate. When the moving rod 41 rotates to a place where there is no tooth block 42, due to the spring 45 fixed on the push plate 46, the push plate 46 is pulled back, driving the linkage rod 43 to be pulled back together, and when the moving rod 41 rotates to the time when the tooth block 42 cooperates with the linkage rod 43, the push plate 46 is pushed out again, and this is repeated.
