Abstract
A follow-up cutting trolley for spiral steel pipes is simple in structure and allows automatic cutting. Each spiral steel pipe comprises a pipe body; the pipe body is connected to a base through a support roller. The follow-up cutting trolley is disposed below the pipe body and comprises a travelling trolley, a follow-up roller, a cutting head, a pneumatic control device and a cutting device; the pneumatic control device is connected with the follow-up roller; the cutting device is connected with the cutting head; the pneumatic control device and the cutting device are disposed on the travelling trolley on two sides of the pipe body, respectively. The follow-up cutting trolley is disposed below the spiral steel pipe and automatically cuts the spiral steel pipe; during cutting, the spiral steel pipe rotates around a fixed axis, the travelling trolley and the pipe body are synchronous and moves linearly, the follow-up roller attaches to the outer edge of the pipe body and rolls under the action of the pneumatic control device, and guiding is made reliable; the cutting device cuts the pipe body by the aid of the cutting device. The follow-up cutting trolley has the advantages that automation level is higher and cutting quality is guaranteed.
Description
Technical field
The present invention relates to the cut-out dolly for cutting off spiral steel pipe.
Background technology
Spiral steel pipe is made through mechanical progressive forming welding processing by steel band, in the process of shaping welding processing, needs steel pipe cutting according to the length requirement specified.In existing production and processing, needing shutdown to carry out rupturing operation, under steel pipe is moved to cutting knife, through measuring, cutting off; This processing mode both wasted labour, have impact on again production and processing efficiency.
Summary of the invention
The present invention is directed to above problem, provide a kind of structure simple, realize the servo-actuated cut-out dolly of the spiral steel pipe automatically cut off.
Technical scheme of the present invention is: described spiral steel pipe comprises body, and described body is connected on pedestal by support roller; Described servo-actuated cut-out dolly is located at the below of described body, described servo-actuated cut-out dolly comprises walking dolly, follower rollers, cutting head, air-control device and cutter sweep, described air-control device connects described follower rollers, described cutter sweep connects described cutting head, and described air-control device and cutter sweep to be located on described walking dolly and to lay respectively at the both sides of described body.
Described follower rollers contacts the outer rim of described body by described air-control device.
The present invention, by arranging servo-actuated cut-out dolly in the below of spiral steel pipe, achieves the surface trimming of steel pipe; In cutting process, steel pipe fixed-axis rotation, walking dolly is synchronous with body, rectilinear movement, and follower rollers is under the effect of air-control device simultaneously, and laminating body outer rim is rolled, and makes guiding reliable; Cutting head realizes the cutting of body by cutter sweep.Invention increases automatization level, ensure that cut quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1 is body, and 2 is pedestals, and 3 is support rollers, and 4 is walking dollies, and 5 is follower rollers, and 6 is air-control devices, and 7 is cutting heads, and 8 is cutter sweeps.
Detailed description of the invention
As shown in Figure 1, described spiral steel pipe comprises body 1 in the present invention, and described body 1 connects on the base 2 by support roller 3; Described servo-actuated cut-out dolly is located at the below of described body 1, described servo-actuated cut-out dolly comprises walking dolly 4, follower rollers 5, cutting head 7, air-control device 6 and cutter sweep 8, described air-control device 6 connects described follower rollers 5(and namely realizes controlling follower rollers 5 by cylinder-driven mechanism), described cutter sweep 8 connects described cutting head 7, and described air-control device 6 and cutter sweep 8 to be located on described walking dolly 4 and to lay respectively at the both sides of described body 1.
In cutting process, body 1 rotates with the speed of setting, and servo-actuated cut-out dolly is simultaneously with the speed displacement of setting, and complete cutting, surface trimming improves production efficiency.
Described follower rollers 5 contacts the outer rim of described body 1 by described air-control device 6, realizes the control to follower rollers by air-control device, and make action more reliable, guiding accurately.
