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 rod large coil (generally referred to as a wire rod coil with the diameter of phi 15 mm-phi 50 mm) production line. The coiler drum is perpendicular to the horizontal plane. The wire is rolled out from the rolling mill, turned by the steel-dividing turnout, alternately enters a section of arc-shaped guide groove structure matched with the coiling machine, turned from horizontal to downward bent, then enters the coiling machine reel through the coiling machine spiral pipe, and finally is coiled and formed. The arc-shaped guide groove structure consists of a plurality of guide devices, and a section of arc-shaped channel is formed by arranging the guide devices according to a certain angle.
In the production process, the wire rod passes through the middle of the arc-shaped channel, and the guide pipe plays a role of guiding the head of the wire rod into the next guiding device. The guide wheels of the guide device are contacted with the wire rod in a staged manner, so that the transition from straight to downward bending of the wire rod is guided and supported.
The two reels of the coiling machine alternately receive the wires sent by the rolling mill in turn, namely, when one section of arc-shaped guide groove structure passes the wires, the other section of arc-shaped guide groove structure is in a waiting state. Namely, the arc-shaped guide groove structure is used intermittently all the time in the production process. In addition, even if the wire is passing through a segment of an arcuate guide slot, not all of the guides on the arcuate guide slot or all of the guide wheels on the guides are in a rotating state. I.e. most of the time, part of the guide wheels on the guide are stationary.
The external shower water pipes of every guider are many, and the lubricated pipe of oil gas is many, and the pipeline reservation overlength easily causes crisscross each other, and the pipeline reservation is short then further increases the installation, dismantles the degree of difficulty. The on-site space is limited, at least 1 guide wheel of each guide device is in a hidden position, the guide wheel state of the hidden position cannot be confirmed in the production process, and even if the guide wheel is stopped, the guide wheel is influenced by staggered complicated pipelines, so that the guide wheel cannot be inspected and maintained. The failed guide wheel can not be found and maintained in time, and the contact between the guide wheel and the wire rod is changed from rolling friction to sliding friction to scratch the surface of the wire rod.
When the guide wheel close to the inner side or the lower hidden position on the guide device is required to be removed or overhauled, the oil-gas lubrication pipe on the guide wheel seat is required to be removed, the cooling water pipe is pulled out, the guide wheel seat and the guide pipe are loosened, the guide wheel seat is rotated to enable the guide wheel to be replaced to rotate to the upper side, and then the guide wheel pin shaft, the bearing, the guide wheel and other relevant replacement steps can be carried out. The oil pipe is affected by space stenosis when being reloaded after completion, the operation difficulty is big, the maintenance consumes time to be long, and maintenance quality is difficult to guarantee. Often, because the oil-gas pipe joint loosens and leaks, the oil gas is insufficient in supply, and then cooling water erodes the bearing; or the external cooling water pipe is loose, and abnormal abrasion or bearing failure caused by poor cooling of the guide wheel due to inaccurate alignment.

The existing guide device 10 has no need of maintenance sealing bearings, and cooling water sprayed on the surface of the guide wheel 400 still can permeate into the guide wheel 400 bearings through gaps when the guide wheel 400 is not rotated, so that the lubrication environment is damaged or the bearings are corroded. Only if oil gas is continuously supplied into the bearing, the cooling water is purged by utilizing the overflowed compressed air, so that the cooling water can be prevented from being immersed. As such, excessive oil and gas is wasted in a large amount and increases the risk of environmental pollution.
In this embodiment, grease lubrication is used instead of oil-gas lubrication, dry oil is filled in the inner space of the bearing and the guide wheel 400, and the bearing assembly is protected from cooling water by using the viscosity of the dry oil higher than that of the thin oil. According to the equipment operation time, grease is supplemented periodically, so that the bearing lubrication environment is not damaged, and unnecessary loss caused by continuous oil gas supply is saved.
