Description
Technical Field
The invention relates to the field of wire coiling equipment, in particular to a guide device and an arc-shaped guide groove structure.
Background
The coiling machine is a key device on a wire large coil (generally, a wire coil with the diameter of phi 15 mm-phi 50 mm) production line. The coiler drum is perpendicular to the horizontal plane. The wire rod is rolled out from the rolling mill, turned by the steel branch way, and alternately enters a section of arc guide groove structure matched with the coiling machine, the arc guide groove structure is turned from horizontal to downward bending, and then enters a coiling machine winding drum through a coiling machine spiral pipe, and finally is coiled and formed. The arc-shaped guide groove structure is composed of a plurality of guide devices, and the guide devices are arranged according to a certain angle to form a section of arc-shaped channel.
During production, the wire passes through the middle of the arc-shaped channel, and the guide pipe plays a role in guiding the head of the wire to enter the next guide device. The guide wheel of the guide device is contacted with the wire in stages, and the guide device is used for guiding and supporting the transition of the wire from straight to downward bending.
The two winding drums of the coiling machine sequentially and alternately bear the wire rods sent by the rolling mill, namely when one section of the arc-shaped guide groove structure passes through the wire rods, the other section of the arc-shaped guide groove structure is in a waiting state. Namely, the arc-shaped guide groove structure is used discontinuously all the time in the production process. In addition, even if the wire is passing through a segment of the arc-shaped guide groove, all the guides or all the guide rollers on the guides are not in a rotating state. That is, most of the time, part of the guide wheels on the guide device are in a static state.
The external spray header of every guider is many, and the lubricated pipe of oil gas is many, and the pipeline is reserved the overlength and is made crisscross each other easily, and the pipeline is reserved partially the short then further increase the installation, is dismantled the degree of difficulty. The field space is limited, at least 1 guide wheel of each guide device is in a hidden position, the state of the guide wheel in the hidden position cannot be confirmed in the production process, and the guide wheel cannot be inspected and maintained even if the machine is stopped and the machine is influenced by the staggered and complicated pipelines. The failed guide wheel cannot be found and maintained in time, and the contact between the guide wheel and the wire is converted from rolling friction to sliding friction to scratch the surface of the wire.
For the guide wheel close to the inner side or the hidden position below the guide device, when the guide device needs to be dismounted or repaired, the oil-gas lubrication pipe on the guide wheel seat needs to be dismounted, the cooling water pipe is pulled out, the guide wheel seat and the guide pipe are loosened, and the guide wheel seat is rotated to enable the guide wheel to be replaced to rotate to the upper side, so that the relevant replacement steps of dismounting the guide wheel pin shaft, the bearing, the guide wheel and the like can be implemented. The oil pipe is subjected to narrow space influence after the completion, the operation difficulty is high, the overhaul time consumption is long, and the overhaul quality is difficult to ensure. The problem that the oil gas supply is insufficient and then cooling water erodes a bearing due to loosening and leakage of an oil gas pipe joint often exists; or the external cooling water pipe is loosened, and the contraposition is inaccurate, so that the guide wheel is badly cooled, and abnormal abrasion or bearing failure is caused.
