The left end of the valve plate 4 is fixedly connected with a rubber layer 20, and the left end of the rubber layer 20 can be contacted with a pipeline to be processed as shown in figure 3. The arc-shaped clamping block is also provided with a feed inlet for adding lubricating oil.

As shown in fig. 1 and 4, the bending mechanism includes a column 15 and a bending portion 18, the column 15 is located at one side of the arc-shaped clamping block 2 and is fixedly disposed on the frame 1, and an arc-shaped curved surface for making the pipe and the side surface of the column 15 more fit is integrally formed in the middle of the column 15. One side of the bending part 18 close to the upright post 15 is integrally formed with an arc-shaped curved surface for coating the pipeline, and the right side of the bending part 18 is fixedly connected with a handle 7. A rotating shaft 16 is coaxially and rotatably connected in the upright post 15, and a connecting portion 17 is fixedly arranged between the rotating shaft 16 and the bending portion 18, in this embodiment, the connecting portion 17 is a connecting rod.

The specific implementation process is as follows: as shown in fig. 1, when in use, the bending part 18 is rotated 90 ° counterclockwise to make the gap between the bending part 18 and the upright post 15 and the gap between the two arc-shaped clamping blocks 2 in the same straight line, the pipe is placed between the two arc-shaped clamping blocks 2 from the left end of the arc-shaped clamping block 2, and then the pipe is pushed to the right to make the part of the pipe to be bent slide between the upright post 15 and the bending part 18.

When the device for bending the pipeline is not used, the valve plate 4 can be fixed at the position of the discharge port 8 by hard objects such as wood blocks, and the discharge port 8 is in a closed state. During the use, add a certain amount of lubricating oil to arc grip block 2 in through the feed inlet, will, take out hard thing and let valve plate 4 slide under the effect of pressure spring 20 thereby make discharge gate 8 be in the open mode, lubricating oil flows to on the fat liquoring layer 19 through discharge gate 8. When the pipeline slides, the lubricating oil coating layer 19 on the two arc-shaped clamping blocks 2 is rubbed with each other, so that the purpose of coating the lubricating oil on the lubricating oil coating layer 19 on the outer surface of the pipeline is achieved.

And the pipeline can push down because self gravity, and rubber layer 20 is located arc grip block 2 lower half part, so can press on rubber layer 20 and thereby move right together with rubber layer 20 mutual friction drive rubber layer 20 when the pipeline slides, thereby rubber layer 20 drives valve plate 4 and moves right so that valve plate 4 slides the position of discharge gate 8 and blocks up discharge gate 8 to the lubricating oil that a large amount of lubricating oil flow out from discharge gate 8 has been avoided extravagant. Therefore, the scheme can automatically paint lubricating oil for the pipeline and save the lubricating oil; meanwhile, when lubricating oil is sufficient at the beginning, the smearing position is just the part of the right end of the pipeline needing to be bent, and the smearing position after the lubricating oil on the later-stage oil coating layer 19 is gradually reduced is the part needing no bending processing, so that the scheme can save the lubricating oil and meanwhile guarantee that the lubricating oil is smeared at the most needed position. The left end of pipeline is located between two arc grip blocks 2, and the right-hand member propelling movement of pipeline is to the stand 15 and the kink between 18 after, clockwise rotation kink 18 drives the right-hand member rotation of pipeline, and then has realized buckling to the pipeline.

At the initial stage of the rotation of the bent portion 18, the left end of the pipe is located in the arc-shaped curved surfaces of the two arc-shaped clamping blocks 2, so that the left end of the pipe cannot swing even if the bent portion 18 is rotated. And rotate kink 18 and can drive axis of rotation 16 and rotate together, and axis of rotation 16 drives incomplete gear 9 and rotates, and incomplete gear 9 drives the rack and removes, and the rack drives driven gear 12 and rotates, and driven gear 12 drives two-way lead screw 11 and rotates, and two-way lead screw 11 rotates and drives two bases 10 and do the opposite motion, thereby base 10 drives two arc grip blocks 2 and does the opposite motion thereby realized the purpose that presss from both sides the pipeline tightly. The present solution is such that the pipe can be clamped by starting the turning of the bent part 18.

When the bending part 18 is rotated continuously, the bending part 18 drives the incomplete gear 9 to rotate, but the incomplete gear 9 and the second rack 14 are disengaged, so that the incomplete gear 9 cannot drive the racks to move continuously, and the two arc-shaped clamping blocks 2 can keep a state of clamping the pipeline until the pipeline is bent.

After the pipeline is bent, the bending part 18 at the visual angle of figure 1 is rotated anticlockwise to restore the original position of the bending part 18, the bending part 18 drives the incomplete gear 9 to rotate, the incomplete gear 9 drives the rack to move, the rack drives the driven gear 12 and then drives the bidirectional screw rod 11 to rotate, the bidirectional screw rod 11 rotates to drive the base 10 to restore the original position, the base 10 drives the arc-shaped clamping block 2 to reset, and the pipeline continues to slide rightwards to take out the pipeline which is finished in processing.
