Steel strand combing and bundling production line

Abstract

The invention discloses a steel strand combing and bundling production line. The steel strand combing and bundling production line comprises multiple pay-off reels on which steel stands are arranged in parallel, wherein the single steel strand in each pay-off reel sequentially passes through a strand arrangement structure, a clamping and feeding mechanism, a counting mechanism, a cut-off mechanism and a strand guiding mechanism which are arranged in parallel according to an axial direction and have the same structure, then the multiple steel strands jointly penetrate into a strand pulling mechanism and a bundling mechanism arranged behind the strand pulling mechanism, and the steel strands bundled by the bundling mechanism are weaved and combed to be wound on a winding drum of the winding mechanism. The steel strand combing and bundling production line has the beneficial effects that the automatic production line is used for replacing a manual production manner to complete combing, sizing, cutting-off and coiling of the steel strands, the multiple steel strands are weaved and combed into coils to be cut, steel stand bundles with various lengths required by construction are efficiently produced in factories, the customized steel strand bundles are distributed to construction sites, the factory distribution of the sizing steel strand woven and combed products is realized, a construction method in the prior art is changed, and the efficiency and quality of prestress construction are improved.

Description

technical field [0001] The invention relates to a steel strand wire combing and braiding production line for combing and braiding a plurality of steel strand wires into bundles. Background technique [0002] With the rapid development of China's economy, in the construction of highway and railway bridges, the tensioning process of prestressed steel strands has been widely used. The prior art prestressed steel strand tensioning process is: after the standard steel strands pass through the bridge reserved holes one by one, the steel strands exposed at both ends of the bridge reserved holes are pulled from both ends, thereby The steel strand produces a prestress in the bridge, which meets the needs of engineering design. In the prior art, in the process of passing multiple steel strands through the reserved holes of the bridge one by one, the steel strands are often intertwined, making it difficult to pass through; at the same time, due to the intersection of the steel strands...

Problems solved by technology

In the prior art, in the process of passing multiple steel strands through the reserved holes of the bridge one by one, the steel strands are often intertwined, making it difficult to pass through; at the same time, due to the intersection of the steel strands in the reserved holes, subsequent The uneven tension force of the steel strand leads to poor prestressed tension effect of the steel strand. It often happens that one of the strands will be stretched and broken due to winding, which will affect the construction quality and life of the bridge, and restrict the prestressed construction of the bridge. construction progress affected

[0003] In order to overcome the above-mentioned defects of steel strand tension construction in the bridge reserved hole, manually comb multiple steel strands outside the bridge reserved hole, mark the two ends of the same steel strand, and then A plurality of steel strands pass through the reserved holes of the bridge as a whole, and then install corresponding anchor plates on both ends of the steel strands according to the marks for tensioning. In this way, the steel strands can obtain a good tension effect, but manual straightening is harmful to multiple steel strands. Stranded wire still has the defects of high labor intensity, low efficiency and poor quality
