One kind is novel to take the lead positioning rubber sleeve
Technical field
The utility model relates to a kind of coiling machine rubber bush, are used for cold-rolled sheet recoiling machine system, eliminate flat cold-rolled sheet
Caused belt end seal is taken the lead by cold rolled sheet in coiling process.
Background technique
Currently, the mandrel outer layer of cold rolled sheet coiling machine is all to have one layer of thicker rubber to carry out buffer board band in coiling process
Formed in pressure, reduce strip coiling process in be formed by scratch, improve the surface quality and lumber recovery of strip.But
It is that cannot still eliminate the belt end seal as brought by strip head in this way, so-called belt end seal is from illustrating that attached drawing 1 can find out.
Flat cold-rolled sheet is first wound into head on the mandrel of coiling machine during batching, and the rotation of mandrel drives strip
It is a-circle-by-a-circle to be wound on mandrel, diameter is reduced to rear mandrel to a certain extent and unloads cold rolled strip coil, and here it is flat cold-rolled sheets
Coiling process.Strip begins to be pressed on wrench since the second circle during this, the problem of due to plate thickness, in plate
Head position second layer strip with mandrel will there are a small amount of gaps, pressure when lamina rara externa band is gradually increased between internal layer
Power starts to increase, will be there are the impression of a transverse direction in the position plurality of layers steel plate of wrench, and here it is belt end seals.When serious
It waits, belt end seal has tens layers and is longitudinally up to nearly hundred meters, these steel plates can only do sub-quality products, seriously affect the benefit of enterprise.
Summary of the invention
The purpose of this utility model seeks to solve the problems, such as the belt end seal of cold rolled sheet volume, provide it is a kind of it is novel take the lead it is fixed
Position rubber bush, one block of very soft foamed material is embedded in below coiling machine rubber bush surface layer, reduces this part rubber in this way
The hardness on glue surface layer, strip head falls into rubber bush surface layer after being extruded when strip head is positioned herein, the
Two laminate materials reduce hard contact area when being pressed onto wrench, alleviate the pressure between each layer, reduce belt end seal, pass through experiment
This problem of very good solution, improves lumber recovery.
The technical solution of the utility model is achieved in this way, and one kind is novel to take the lead positioning rubber sleeve, including volume
The rubber bush of machine is taken, its main feature is that:It is provided with long bar-shape groove as outer surface below rubber bush surface layer, sends out
Bubble is filled soft band and is filled in groove, and the corresponding rubber bush outer surface of soft band appearance posts luminescent paper label.
The utility model is filled with foam filled soft band below coiling machine rubber bush surface layer, can make cold-strip steel
Head fall into this soft band, reduce by taking the lead caused so-called strip belt end seal, improve the lumber recovery of cold rolled sheet, structure
Simply, benefit is improved.
Detailed description of the invention
Fig. 1 is the principles of the present invention schematic diagram.
Fig. 2 is that schematic diagram is realized at the scene of the utility model.
Fig. 3, Fig. 4 are soft band rubber bush band head positioning system scene realization principles.
In figure:1, strip;2, rubber bush;3, foam filled soft band.
Specific embodiment
As seen from Figure 1,1 is cold rolling strip to be reeled, and 2 be the cylindric rubber bush of coiling machine, and 3 be in rubber bush
Foam filled soft band.Soft band is strip as seen from Figure 3, and the length as outer surface is provided with below 2 surface layer of rubber bush
The foam filled soft band 3 of bar-shape groove, dead-soft is filled out in groove, and soft 3 appearance of band is the outer surface of rubber bush, in soft band
Rubber bush outer surface corresponding position post luminescent paper label.Strip steel head can be pressed into the roller of rubber bush on the outside of soft band
Face can mitigate the pressure between two layers of strip, mitigate the belt end seal of subsequent strip when second layer strip is pushed down with steel toe.
Strip head is first precisely positioned to the soft band upper surface of coiling machine rubber bush, right later layer one when starting to batch
Layer is rolled into coil of strip.Fig. 2 can see the situation that strip is rolled into after coil of strip, it can be seen that strip batch after belt end seal occur
Region, if position of the belt end seal where go coil of strip when not being equipped with soft band on rubber bush.
Wrench is accurately located in the soft band surface area of rubber bush after pinch roller threading by Fig. 4 tabularium,
Reflective sheeting is posted at the soft band of sleeve and in strip guide table, positioning system transmitting light signal positioning is taken the lead and the soft band position of sleeve
It sets, system Auto-matching electric motor of coiling machine revolving speed is accurately positioned to realize.
Rubber bush internal recessing fills the production technology of foam filled soft band, is guaranteeing rubber using special foam filler
The hardness that rubber is reduced under the premise of sleeve surface is wear-resisting is achieved in and takes the lead to realize sagging, reduction at the soft band of sleeve
Subsequent steel band is in the pressure at the place of taking the lead to reduce belt end seal.
It with rubber bush is for we is the more practical components developed in cold rolled sheet coiling system, warp that this is soft
Scene is crossed using the belt end seal phenomenon that can significantly improve cold rolled sheet, reduction causes waste product because batching, being capable of larger journey
Degree is improved benefit.
