Abstract

A method for slitting titanium and titanium alloy strip coils is characterized in that the titanium and titanium alloy strip coils which are uncoiled adopt the following steps: the process comprises the following steps of clamping and conveying, longitudinal shearing, directional material distribution, pressing plate, coil splitting, winding, coil unloading and packaging. The invention has the beneficial effects that: the method can be used for longitudinally shearing the titanium and titanium alloy strip coil with the opening length of thousands of meters, shearing off the uneven part of the edge of the titanium strip, and longitudinally shearing the wide titanium strip into a plurality of narrow titanium strips with different widths according to the requirements of users; the titanium belt can be only trimmed, and the width of the titanium belt is kept.

Description

A kind of titanium and titanium alloy coil slitting slitting method

technical field

The invention belongs to the technical field of methods for slitting and slitting titanium and titanium alloy coils.

Background technique

Existing titanium and titanium alloy plates are all produced in the form of single plate rolling. Since the length and width of the titanium plate are relatively short (the long side is no more than 6 meters and the short side is no more than 2 meters), it is easier to cut the titanium plate into narrow strips, that is, pass the whole titanium plate through several times. Shearing Trims into smaller titanium plates. In this way, first, the longitudinal shearing of the titanium strip with an open length of thousands of meters cannot be realized, and the second is that the wide-width titanium strip cannot be simultaneously cut into multiple narrow-width titanium strips of the same width or different widths. Continuous production cannot be realized.

Contents of the invention

The purpose of the invention is to solve the problems of longitudinal shearing, slitting and wrapping of titanium strips into rolls.

The purpose of the present invention is achieved through the following technical solutions:

A method for slitting and slitting titanium and titanium alloy strip coils. The invention adopts the process circuit method of pinching-slitting-slitting-directional material splitting-pressing plate-splitting-coiling-uncoiling-packing for the uncoiled titanium strip processing; where:

Pinching is to send the running titanium belt into the longitudinal shearing machine by clamping a pair of rubber rollers;

Slitting is to cut the running titanium strip into multiple narrow titanium strips of different widths along the length direction of the titanium strip through a set of disc scissors arranged on a pair of transverse shaft rollers; at the same time, pass through the outermost two pairs of The disc shear cuts off the irregular part of the edge of the titanium belt, and the cut edge wire is collected into an edge wire roll through the collection wheel arranged on the side of the disc shear;

Directional distribution is to guide the narrow titanium strips separated by slitting through the distribution disc arranged on a pair of transverse rubber rollers, and keep the same gap between adjacent narrow strips and enter the platen table neatly;

The platen guides the slitting narrow titanium strip to the winder through the pinch of the platen table;

Slitting is to cut the slitting titanium strip into rolls of different lengths according to needs through a transverse shearing machine;

Winding is to guide the narrow titanium strip through a group of directional distributing discs arranged above the winding mandrel, and to be wound into multiple narrow titanium rolls on the same winding mandrel;

Unwinding is to wrap all the narrow titanium strips into rolls, the rolling trolley supports the titanium coils from below, the winding machine shrinks the expansion block to loosen the inner ring core of the titanium coils, and manually wraps the narrow titanium strips with a strapping belt. The rolls are bundled and fastened, and then the unwinding turntable arranged next to the winder is turned to receive the narrow titanium strip from the winding mandrel shaft, and then the unloading turntable is turned to transport the narrow titanium strip to the packaging table Carry out paper wrapping, packing on.

The beneficial effect of the present invention is that, adopting the method of the present invention can longitudinally cut titanium and titanium alloy coils with a length of more than one thousand meters, cut off the irregular parts of the titanium strip, and cut the wide titanium strip according to the user's The slitting is required to be divided into several narrow titanium strips with different widths; it is also possible to only trim the titanium strips to keep the width of the titanium strips.

The content of the present invention will be further described below in conjunction with the examples.
