Description

I

The tensioning device of the slitter of the slitting unit relates to the processing of metals by pressure and, in particular, to devices for the processing of the tape.

A separating device is known, consisting of two rollers with separating rings mounted on them, which have helical grooves on the outer surface. The pitch of the screw grooves is different: by the middle of the roller - the smaller one, to the edge of the roller - the larger one. Fingers rigidly connected to the frame are inserted into the slots. The rollers are interconnected by a gear.

The drawback of the device is the unreliable separation of the strips and their uneven tension during winding on the drum of the winder.

It is also known a tension-tensioning device for a winder of a strip slitting unit, comprising a separation roller and tensioning device.

The disadvantage of the device is that the tension device unevenly stretches the strips. Which leads to their oscillation in the transverse plane and to overlap.

The purpose of the invention is to improve the quality of winding.

This goal is achieved by the fact that in the separating-tensioning device of the winder of the unit for longitudinal cutting of the strips containing the separating roller and the tensioning device, the tensioning device is made in the form of a series of L-shaped brackets with trunnions mounted on pivotal hinges.

IS levers with rollers at the end, pneumatic brackets hinged on the L-shaped brackets and connected with pivoting levers, while the L-shaped brackets are installed with the possibility of moving perpendicular to the line of the & coil.

FIG. I shows a diagram of the installation of machines and separating devices in front of the coiler of the slitting unit; in fig. 2, section A-A in FIG. 1 (supporting and tensioning rollers); in fig. 3 is a view B in FIG. 1, in FIG. 4 shows a section B-B in FIG. 2 (view of the main elements of the tensioning device); in fig. 5 a section of YYY in FIG. 4. The proposed tension-tensioning device consists of three main mechanisms: a separation device, tensioning device, and folding wiring. The separating device consists of a pivoting lever, a roller 2 with separating discs 3. The tensioning device consists of a bed 4 on which the supporting roller 5 is inserted and fixed from above, the deflecting roles 6, the rod 7 by the clamping rollers 8. The rollers 8 are fixed on the swinging arms 9, pivotally mounted on the trunnions of the G-shaped brackets 10, the upper L-shaped brackets 10 can be moved along the rod 7, while holding the key 11 from turning the lever 10, and fixing the position is carried out with the screw 12. The key 11 also passes through hole in a hanger 13 connecting the rod to the bed 4 and excluding the rod 7 turning. The L-shaped bracket 10 with the swinging arms 9 are connected by pneumatic cylinders 14, which drive the swinging arms 9 with the tension rollers 8. The folding wiring consists of wired the sheet 15, which is fixed hingedly to the frame of the pulling rollers, and the pneumatic cylinder 16. The separation-tensioning device works in the following manner. The sheet passes through the disc shears knives and is cut into strips. Further strips are included in the t rollers. The wire sheet 15 is lifted and the strips, having passed through the tensioning device, enter the slot of the reel drum. The drum begins to rotate, winding the first few turns. The separation roller 2 is lowered down, the wire sheet 15 is lowered, the cylinders 14 of the tensioning device are turned on 4. Swivel levers 9 go down and press down on the strips. Each strip is pulled by its roller. Before the end of the cutting and coiling, the swivel arms 9, separator roller 2, wire sheet 15 are raised upwards. When retracting the tensioning device into strips of a different width, the L-shaped brackets 10, after screwing the screw 12, are moved apart to the required width and fixed again with the screws 12. The proposed tensioning tensioning device allows to produce high-quality winding of the strips onto the reel winder, cut; from a sheet that does not have an ideal plane, but is quite suitable for production, to completely eliminate the marriage of adhesion of rolls, improves the working conditions of metal carvers. Claims Separation-tensioning device of a winder of a strip slitting unit, comprising a separation roller and tensioning device, characterized in that, in order to improve the quality of winding, the tensioning device is made in the form of a series of L-shaped brackets with pins, set-. pivoting arms with rollers at the end, pneumatic cylinders pivotally mounted on L-shaped brackets and connected with pivoting levers, while the L-shaped brackets are installed with the possibility of moving perpendicularly the winding line.
