SU1237328A1 - Arrangement for lengthwise cutting - Google Patents

Description

The invention relates to disc shears and can be used in petroleum and chemical engineering in the manufacture of a regular packing for mass transfer columns by cutting sheet mesh material into corrugated strips.

The aim of the invention is the expansion of technological capabilities as a result of combining the operation of cutting sheet material into strips while simultaneously applying corrugations on these strips.

Figure 1 presents the device, a General view, figure 2 - section aa in figure 1.

The slitting device consists of two synchronously rotating drive shafts 1 arranged in parallel with spacer sleeves 2 and 3 and disk gear knives 4 mounted on them. Remote sleeves 2 and 3 are made with gear teeth with the required corrugation profile and form gearing. Distance

The sleeves 2 and 3 are made of two different diameters, the alternation of cix along the axis of the shafts 1 so that the gear sleeves 2 of the same diameter are mounted on shafts 1 on the key 5, the sleeves 3 of a different diameter are mounted on the shafts 1 on bearings 6, the knife pair is formed disk gear knives

4 along the ends of the spacer sleeves 3 of large diameter, with the teeth of the serrated knives forming a pair, are located between each other's teeth.

 The device operates as follows. .

The sheet material is fed into the zone of gearing formed by distance sleeves 2 and 3 and disk-shaped knives 4. This material 7 passes through a pair of knives formed by disk-shaped gear knives 4. The sleeves 2 of the same diameter are mounted on synchronously rotating shafts 1 on

key 5 and rotates the splicing gear of the sleeve 3 of a different diameter, mounted on the subsurface 6, and the material 7, the passage between the sleeves 2 and 3, is cut into

strips with simultaneous execution of the corrugations, and the finished product 8 is obtained; in this case, the role of the continuous punch is performed by the remote gear sleeves 2 and 3 and the disk gear

25 knives 4.

one

As a result of combining operations

cutting and corrugating strips in the proposed device increases labor productivity, since one driver will simultaneously perform the operations of cutting sheet material on strips and applying bumps on them.
