[0041] Since the cross-section of the channel steel 35 is a rectangular structure, the processed raised rib 33 and the processed support frame 6 can effectively support the bottom and one side of the channel steel 35.

The chamfering device on the second processing table 46 is set in a mirror image of the one on the first processing table 45; the chamfering machine 50 on the first processing table 45 is controlled to move longitudinally, transversely and up and down to meet the movement of different positions, and the position is continuously adjusted to chamfer different ends of channel steels 35 to adapt to different sizes of channel steels 35. It has good flexibility and improves the use effect. The chamfering machine 50 is an existing structure available on the market, so it is not described in detail in the text.

[0045] The working principle of this embodiment is as follows: first, the channel steel 35 is transported to the loading support frame 4, and the channel steel 35 is against the loading raised rib 31, then the guide rod of the lifting drive cylinder 16 is contracted, the hinged connecting rod 12 descends, and the conveying frame 7 descends, so that the conveying support frame 8 follows the decline, and the guide rod of the transverse telescopic cylinder 20 extends to drive the conveying frame 7 to move laterally to the loading support frame 4, and the conveying support frame 8 is located below the loading support frame 4, and then the conveying support frame 8 rises, and the channel steel 35 on the loading support frame 4 is supported by the upper conveying trough 9, and at the same time, the clamping claw 23 clamps the channel steel 35, and the conveying support frame 8 is transported to the processing support frame 6, and then it descends again, and the channel steel 35 on the upper conveying trough 9 falls on the processing support frame 6, and the channel steel 35 is against the processing raised rib 33, and the conveying support frame 8 continues to descend. , and then slide back to the loading support frame 4 to re-convey the new channel steel 35, and then the pressing telescopic cylinder 44 drives the pressing block 38 to move toward the processing support frame 6. When the positioning portion 39 contacts one side of the channel steel 35, it will push the channel steel 35 to move until it rests against the processing raised rib 33, and the pressing portion 40 will also press the upper surface of the channel steel 35. Then the end of the channel steel 35 is chamfered by the chamfering machine 50. After the processing of the channel steel 35 on the processing support frame 6 is completed, the lower conveying trough 10 of the conveying support frame 8 will lift up and support the channel steel 35, and the channel steel 35 relies on the conveying raised rib 34 on the lower conveying trough 10. Then when the upper conveying trough 9 slides onto the processing support frame 6, the lower conveying trough 10 slides onto the unloading support frame 5, and finally descends to make the channel steel 35 fall on the unloading support frame 5 to complete the conveying.

[0046] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Various modifications and alterations to the technical solution of the present invention, without departing from the design spirit of the present invention, should fall within the scope of protection defined in the claims of the present invention.
