Description

Uncoiler installation paper sleeve clamp

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of auxiliary tools for calendering non-ferrous metal plate strips and foils, in particular to a fixture for installing a paper sleeve on an uncoiler.

[ background of the utility model ]

As is known, sleeve devices on uncoilers of calendaring processing equipment in the non-ferrous industry are divided into an expanding shaft type and a conical head type, and the two modes only can meet the installation requirement of a steel sleeve. The expanding shaft type uncoiler has a complex structure and is expensive, so the expanding shaft type upper sleeve device is mainly used for a cold rolling and cogging process. The clamping cone head type working principle utilizes an uncoiler to uncoil a steel sleeve with a fixed size on the conical surface of a cone head, and two symmetrical cone head keys are installed on the excircle of the conical surface to prevent the sleeve from slipping during high-speed rotation. The conical heads in the two forms can only meet the installation requirement of a steel sleeve, an enterprise can send out aluminum coil products generally, a coil core generally adopts a paper sleeve, and if the outgoing products need to be reformed and produced or scrapped due to quality problems or business returns and the like, the outgoing products need to be recoiled onto the steel sleeve through a professional recoiler, and then the outgoing products begin to be reformed and produced or scrapped again.

If the tool is not increased through technical improvement, the rewinding machine needs to be independently purchased to solve the contradiction, the investment cost of enterprises is increased by newly adding equipment, and the labor intensity of material turnover between working procedures is increased.

[ summary of the utility model ]

In order to overcome the defects in the background art, the utility model discloses a paper sleeve mounting clamp for an uncoiler. The clamp can meet the condition that the paper sleeve is installed on the main equipment of the rolling mill, simultaneously solves the problems that the paper sleeve is easy to deform, slip, string layers and the like under the clamping of the hydraulic conical head, and solves the contradiction between the direct rolling mill remanufacturing or scrapping of the finished product paper sleeve aluminum coil and the original equipment.

In order to achieve the purpose, the utility model provides the following technical scheme:

a paper sleeve mounting clamp for an uncoiler comprises a movable clamping device and a clamping conical head, wherein two symmetrical conical head keys are mounted on the excircle of the clamping conical head; the inner conical sleeve is internally embedded with a supporting sleeve, a space ring is arranged on the supporting sleeve, and three symmetrical small steel keys are welded at the end part of the excircle of the space ring.

Preferably, the support sleeve is fixed in the inner cone sleeve by welding.

Preferably, the inner diameter of the inner taper sleeve is 665 mm.

Preferably, the outer diameter of the support sleeve is phi 505 mm.

Due to the adoption of the technical scheme, the utility model has the following beneficial effects:

the application has solved the unable direct mount of paper sleeve and has been pressed from both sides tight awl head at former decoiler, and the finished product of enterprise's outward shipment returned goods can directly go up the decoiler and reform transform the production or directly draw useless, has avoided the unable problem of returning goods and reform transform of finished product quality objection coiled material. Before the transformation is not carried out, the outgoing finished products with quality objections can be solved only by product degradation and price reduction, or the outgoing finished products are manually scraped one by one after being pulled back to the furnace. The yield of company products is improved to the maximum extent after transformation, and the profitability of enterprises is improved.

[ detailed description ] embodiments

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the paper sleeve mounting clamp for the uncoiler comprises a movable clamping device 1 and a clamping cone head 4, wherein two symmetrical cone head keys 9 are mounted on the outer circle of the clamping cone head 4, the paper sleeve mounting clamp further comprises an inner taper sleeve 5 matched with a cone head seat on the clamping cone head 4, and the inner diameter of the inner taper sleeve 5 is phi 665mm and is formed by combining two circular sleeves with different diameters; the key groove on the outer circle of the inner taper sleeve is matched with the taper head key 9 and used for preventing the composite sleeve device from slipping at high speed. Support cover 6 is inlayed to interior taper sleeve 5 inside, supports 6 accessible welded fastening of cover in interior taper sleeve 5, supports the cover and is used for installing paper sleeve 2, increases paper sleeve 2's intensity. The outer diameter phi of the support sleeve 6 is 505mm, a space ring 8 is arranged on the support sleeve, and three symmetrical small steel keys 7 are welded at the end part of the excircle of the space ring. When clamping tightly, 2 excircle terminal surfaces of paper sleeve are extruded to little steel key 7, prevent that paper sleeve and conical head 4 from skidding appearing, can adjust according to the strip of different width during production, install different spacer rings, avoid paper sleeve lateral displacement to appear in normal production process.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the utility model can be made, and equivalents and modifications of some features of the utility model can be made without departing from the spirit and scope of the utility model.
