RU209818U1 - Device for winding two corrugated tapes on the steel core of the cowper heater nozzle - Google Patents

Abstract

The utility model relates to mechanical engineering and can be used in the manufacture of nozzles for cowper heaters. The device contains a steel cylinder placed on the base, in which the steel core of the nozzle is installed to ensure its rotation by means of a torque wrench. The diameter of the cylinder corresponds to the diameter of the finished cap of the cowper heater. The cylinder has a slot for supplying corrugated tapes to the core. The feed is carried out between two rollers with a torque set by torque wrenches. Sliding side racks are provided, between which the cylinder is located to ensure its rigid clamping by the racks and removal together with the wound tapes. As a result, the quality of the obtained nozzle is improved. 2 ill.

Description

The utility model relates to rolling production, in particular to the design of a device for winding corrugated tape into a roll.

A device for winding a tape into a roll is known (patent RU 13792 U1, B65N 18/00, publ. clamping the tape to the mandrel.

The device allows winding steel corrugated tape into a roll with high productivity.

The disadvantage of the known device is the inability to control the amount of tension of the tape; the inability to control the size of the gaps in the center of the winding (at the core) and at the exit of the tape (near the steel cylindrical billet of the heat exchanger nozzle), as well as the complexity of the design.

The objective of the claimed utility model is to reduce the size of the gaps at the core, between the turns of the tape and at the exit of the tape (near the steel cylindrical billet of the heat exchanger nozzle) and simplify the design. The technical result of the application of the utility model is to improve the quality of manufacturing nozzles of the cowper heater.

Figure 1 shows a general view of the installation for winding corrugated tapes on a steel core.

In Fig 2. - view of the installation from the side.

The device for winding two corrugated tapes on the steel core of the cowper heater nozzle is characterized in that it contains a steel cylinder placed on the base, made with the possibility of installing a steel core in it to ensure its rotation by means of a torque wrench and having a diameter corresponding to the diameter of the finished cowper heater nozzle, and a slot for supplying corrugated tapes to the core, carried out between two rollers with a moment set by torque wrenches, ensuring rigid fastening of the ends of the tapes on the core, and sliding side racks, between which the said cylinder is located, ensuring its rigid clamping by racks and removal together with wound ribbons.

The installation works as follows.

The edges of the two corrugated tapes stacked on top of each other are welded to the core 1, for example, by spot welding. The core is installed in a fixed steel cylinder with slots for feeding the tape 2, clamped by sliding side posts 4 with the help of a pin 5. A feature of the cylinder is the presence of a slot through which the tape enters the core. The diameter of the cylinder must match the diameter of the finished nozzle. The torque wrench 3 attached to the core 1 rotates the core. Thus, the tape is wound on the core. After 3-7 turns, the torque on key 4 must be increased to create a tight winding.

Before winding the tapes on the core, the edges of the tapes are cut off and ground to form a wedge-shaped section. The torque wrench 4 makes the final turn to create the most dense winding with minimal gaps near the inner shell of the cylinder 2. After winding is completed, the slotted cylinder will be removed along with the wound tape.

The entire process of winding tapes is carried out manually, under constant visual control to prevent the tape from shifting and to carry out winding with a given density.

As a result of using the scheme with adjustable torque, the tape winding is carried out evenly without gaps between the turns of the tape.

The proposed utility model provides winding of corrugated tapes on a steel core without the formation of gaps at the core, between the turns of the tape and at the exit of the tape.
