Abstract
The utility model relates to a rotation assisting device for a rolling steel tube. The rotation assisting device for the rolling steel tube is characterized comprising a triangular chuck, a feed-in trolley, a rotating device and an adapting piece. The rotating device is arranged on the feed-in trolley and connected with the triangular chuck through the adapting piece. Compared with the prior art, the rotation assisting device for the rolling steel tube has the advantages of being fine in rotating effect and free from twisting off a mandril. Due to the steel tube capable of penetrating through the triangular chuck, the length of the tube is infinitized.
Description
Technical field
The utility model relates to a kind of rolled steel tube and helps rotary device, is used for the cold-rolled process of steel pipe, rotates while steel pipe is travelled forward, and it is parts of cold rolling machine tool that this rolled steel tube helps rotary device.
Background technology
In the present steel pipe manufacture process, owing to limit by cold rolling machine tool lathe bed length, the rolling pipe of institute's energy is the longest for lathe bed length deducts the length of feeding trolley and bracing frame, has greatly limited the length of production pipe.In addition, when rolling super thick pipe, thereby the rotation of pipe is to connect plug by core bar to make plug drive pipe, because the pipe own wt is excessive, so that moment of torsion is excessive, thereby makes plug can not drive the pipe rotation or twists off plug.
The utility model content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and is simple in structure, and simple installation is easy to maintenance, makes simply, can prevent that the rolled steel tube that twists off plug from helping rotary device.
The technical scheme in the invention for solving the above technical problem is: this rolled steel tube helps rotary device, it is characterized in that: comprise triangle chuck, feeding trolley, whirligig and connector, described whirligig is installed on the feeding trolley, and described whirligig is connected connector with the triangle chuck and connects.
Connector described in the utility model is fixed by screws on the whirligig.
The utility model compared with prior art has the following advantages and effect: rotate effect is good, can effectively avoid twisting off plug.Because steel pipe can pass the triangle chuck, so that the length of pipe is unrestricted.
Description of drawings
Fig. 1 is the structural representation that the rolled steel tube of the utility model embodiment helps rotary device.
Fig. 2 is the use state diagram that the rolled steel tube of the utility model embodiment helps rotary device.
Label declaration: triangle chuck 1, feeding trolley 2, whirligig 3, connector 4, cold rolling machine tool 5, steel pipe 6.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
As depicted in figs. 1 and 2, originally be that the rolled steel tube of embodiment helps rotary device to comprise triangle chuck 1, feeding trolley 2, whirligig 3 and connector 4, whirligig 3 is installed on the feeding trolley 2, and whirligig 3 is connected with the triangle chuck by connector 4 connections.
The connector 4 of present embodiment is fixed by screws on the whirligig 3.The parts that whirligig 3 of the present utility model all carries for general cold rolling machine tool 5, steel pipe 6 can pass whirligig 3, and whirligig 3 can rotate.The whirligig 3 of present embodiment is comprised of rotary sleeve and motor, and motor is connected with rotary sleeve, and rotary sleeve is connected connection with connector, and motor can drive the rotary sleeve rotation, and steel pipe 6 can pass rotary sleeve.
When the utility model used, feeding trolley 2 was installed on the cold rolling machine tool 5, and feeding trolley 2 can be set with core bar in the steel pipe 6 in cold rolling machine tool 5 operations, and core bar is connected with plug.
Above content described in this specification only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
Claims (2)
