Prestressed steel wire marshalling equipment mainly includes steel wire reeling machine, steel wire rack, steel wire wave press, corrugated fixture, fixture assembly table, fixture press, steel wire stretching machine and pendulum wire friction saw. Wire grouping mainly includes the following processes:
1. The steel wire is inverted. The steel wire that has passed the inspection is transported from the warehouse to the workshop, and the steel wire is inverted on the wire reel by the wire reeling machine.
2. Install the steel wire reel. After the steel wire is installed on the wire reel, the wire reel is installed on the wire reel frame. Each assembly line has two steel wire tray racks, and 48 steel wire trays can be installed.
Three, steel wire pressure wave. In order to improve the bond strength between the steel wire and the concrete when the smooth steel wire is used, the steel wire needs to be subjected to pressure wave treatment. After the steel wire passes through the toothed sub-wave roller, a wave-shaped steel wire is formed. The wave pitch is generally 40 mm and the wave height is 1.5-2.0 mm.
Fourth, steel wire positioning. The steel wire passes through the steel wire positioner (horizontal positioning and vertical positioning) at the front end of the fixture assembly table after pressure wave, so that the steel wires are arranged in position and enter the fixture assembly table.
5. Install the corrugated fixture. The corrugated clamp can hold the group of steel wires firmly for tensioning. There are two types of corrugated clamps currently used, one is a two-wave clamp and the other is a three-wave clamp. When installing the corrugated fixture, place the corrugated clip between each layer of steel wire on the fixture assembly table, and then press it with a corrugated fixture press and tighten the nut. In this way, the whole group of steel wires are compressed, and the position of the steel wires can also meet the design requirements.
Six, drawing wire group. Pull the installed corrugated fixture with a steel wire stretching machine along the stretching machine table from one end to the other. Since each steel wire receives a certain group force when the steel wire passes through the wave press, each steel wire in the steel wire group can basically maintain the same length. The corrugated clamp at the end of the steel wire group is pulled to a certain position on the stretching machine and automatically stops stretching under the control of the stroke switch. Then install two sets of corrugated clamps continuously at the other end of the wire group.
Seven, cut the wire. When the corrugated clamps are installed at both ends of the steel wire group, the steel wire is cut with a pendulum friction saw. This completes the marshalling of a steel wire group.
8. The steel wire is inserted into the mold. The wire grouping process is continuous. The clamp hook of the stretching machine can be woven into a wire group with a vise back and forth. After the steel wire grouping is completed, move the steel wire together with the corrugated clamps at both ends into the sleeper model.
