Working principle: opening the flip cover 2 to expose the placement groove 11, then placing the bar, closing the flip cover 2, and finally pushing the bar through the feeding system 3, wherein in the pushing process of the bar, the oil supply mechanism 51 is used for ensuring that the oil delivery pipe 522 is filled with hydraulic oil, and then the control system 53 is used for enabling the hydraulic oil flowing in the oil delivery pipe 522 to drop into the placement groove 11 along each branch pipe 523 in sequence to lubricate the placement groove 11; when the feeding system 3 returns, part of the hydraulic oil is pushed out of the placement groove 11, at this time, the hydraulic oil is drained through the diversion bucket 541 arranged on the frame 1, and finally the hydraulic oil flowing down along the diversion bucket 541 is recovered by the collecting bucket 542.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. within the design concept of the present invention should be included in the scope of the present invention.
