Abstract
The utility model belongs to a strip threading and leading device for making a steel coil strip head smoothly pass through a centering device and reach a pinch roller when a rolled steel plate strip cold-rolling mill carries out single coil rolling and strip threading, and in particular relates to a cold-rolling strip threading and leading head device. A connecting rod is fixedly connected to one end of a rotating shaft installed through a bearing seat, the other end of the connecting rod is hinged with the end of a cylinder piston rod, two pinch roller arms are uniformly and fixed connected to the middle part of the rotating shaft along the axis, and pinch rollers are arranged at the ends of the pinch roller arms, wherein the included angles between the connecting rod and the pinch roller arms are 43 to 47 degrees; and guiding pressure levers vertical to the axis of the rotating shaft are uniformly and fixed connected to the rotating shaft on one side opposite to the pinch roller arms, wherein the included angles between the pinch roller arms and the guiding pressure levers are 156 to 164 degrees. The device has a simple and compact structure; when the cold-rolling mill carries out single coil rolling and strip threading, the device has a good control effect and high treatment efficiency; and the device is low in manufacturing and maintenance costs, and convenient to install and convenient and fast to operate.
Description
Technical field
the utility model belongs to that steel rolling strip cold-rolling mill monovolume is rolling to be worn when band, and coil of strip is taken the lead smoothly through centralising device, and what arrive pinch roll wears band leader tape device, particularly a kind of cold rolling band leader tape head unit of wearing.
Background technology
1, present domestic cold rolling unit adopt sour continuous rolling technology, only when accident or maintenance occurring, just wear band.
2, domestic newly-built single chassis reversable mill have improved the Equipment Foundations of uncoiler when design, can guarantee when uncoiling, to take the lead from up to down, get into pinch roll smoothly; Cold rolling uncoiler is being worn when band below slewing rollers, centralising device and pinch roll, take the lead to have external force to make it to produce 90 ° turning to, and will have after turning to that the pressure zone steel guarantees centering (the band steel can not exceed the centring roll of centralising device) under the external force.The existing carrying device complex structure of wearing is made, maintenance cost is higher, and it is poor to wear band control effect.
Summary of the invention
The purpose of
the utility model is to provide a kind of cold rolling band leader tape head unit of wearing, and it is simple and compact for structure, in that the cold-rolling mill monovolume is rolling when wearing band, control effectively, and treatment effeciency is high, and manufacturing and maintenance cost are low, easy for installation, simple operation.
The purpose of
the utility model is achieved in that a kind of cold rolling band leader tape head unit of wearing; The rotating shaft one of which end of installing through bearing block affixed connecting rod; The other end of connecting rod and the end of cylinder piston rod are hinged; Be uniformly distributed with affixed two pinch roller arms at the middle part of rotating shaft along axis, in the end of pinch roller arm pinch roller be installed, wherein the angle of connecting rod and pinch roller arm is 43 °-47 °; In a side rotating shaft opposite with the pinch roller arm, be uniformly distributed with affixed the guiding depression bar vertical with shaft axis vertically, wherein the pinch roller arm is 156 °-164 ° with the angle of guiding depression bar.
the utility model is installed in the milling train porch.The utility model has adopted the air cylinder driven linkage; The air cylinder driven connecting rod makes the pinch roller installed on affixed guiding depression bar in rotating shaft both sides and the pinch roller arm realize the technology position of leader tape and pressure zone; Realized that band steel toe portion guiding and following pressure zone steel guarantee centering, made the band steel be lower than the centring roll of centralising device.The utility model has realized that band steel toe portion turns to smoothly, carries out getting into roll after the centering.The utility model is simple in structure, compact, has realized wearing when band in that the cold-rolling mill monovolume is rolling, control effectively, and treatment effeciency is high, and manufacturing and maintenance cost are low, easy for installation, simple operation.

To combine accompanying drawing that the utility model is done further to describe below,
Fig. 1 is the main TV structure sketch map of the utility model;
Fig. 2 removes the left TV structure sketch map of cylinder for Fig. 1.
The specific embodiment
a kind of cold rolling band leader tape head unit of wearing; Like Fig. 1, shown in Figure 2; The rotating shaft 5 one of which ends of installing through bearing block 6 affixed connecting rod 2, the end of the other end of connecting rod 2 and cylinder 1 piston rod is hinged, is uniformly distributed with affixed two pinch roller arms 4 at the middle part of rotating shaft 5 along axis; In the end of pinch roller arm 4 pinch roller 3 is installed; Wherein connecting rod 2 is 43 °-47 ° with the angle of pinch roller arm 4, in a side rotating shaft 5 opposite with pinch roller arm 4, is uniformly distributed with guiding depression bars 7 affixed and rotating shaft 5 axis normal vertically, and wherein pinch roller arm 4 is 156 °-164 ° with the angle of guiding depression bar 7.Pinch roller 3 is made up of rubber wheel.The quantity of guiding depression bar 7 is 4.The utility model can be used for the pickling unit of cold-strip steel, leader tape when cold rolling unit, smooth unit, rewinding unit and crosscut unit are worn band.
