There are six processes for the worktable of the winding of the feeding rack (i.e. hexagonal runner). In addition to the mechanical indexing and positioning of the main products, a set of detailed positioning mechanism is also set to determine the accurate positioning of the worktable mold in each stamping process. The sliding table for installing the upper mold is a box structure. The sliding table guide rail has a large contact length with the upper guide rail of the machine body. Each stamping of the upper mold, In the process, there is a secondary stamping on the mud blank, that is, after the upper mold presses the tile blank in place, the upper mold rises by 10 mm, so that the mud blank is deeply and fully vented, and then the upper mold presses the tile blank down in place before returning to the high position. Therefore, the service life of the mold is long and the quality of the pressed products is good. Color steel tile machine will be equipped with a set of lubrication system. When the machine is running, it will automatically add oil to all bearing bearings, transmission gear mechanism, moving guide rail and other parts

the winding structure of the feeding rack is customized on demand to save energy. The products are widely used in the production of various colored steel tiles required for the construction of various industrial plants, warehouses, high-rise buildings and the decoration of large gas stations

cold hardened coil is made of hot-rolled coil after pickling and cold rolling. It can be said to be a kind of cold rolled coil

hot rolled coil is deeply affected by pickling, cold rolling, bell annealing, flattening and finishing

there are three main differences between the two:

1. In appearance, generally, the cold and hard coiled plate is a little dark

2. The surface quality, structure and dimensional accuracy of cold-rolled sheet are better than those of cold-rolled sheet

3. In terms of performance, because the cold-rolled coil, which is directly affected by the hot-rolled coil after the cold-rolled process, has work hardening during cold rolling, resulting in an increase in yield strength and residual part of internal stress, and the external performance is relatively "hard", it is called cold-rolled coil

and cold rolled coil (annealed): the cold-rolled coil is deeply annealed before rolling. After annealing, the work hardening phenomenon and internal stress are eliminated (excellent reduction), that is, the yield strength is reduced close to that before cold rolling

therefore, the yield strength: the cold-rolled coil is larger than the cold-rolled coil (annealed state), which makes the cold-rolled coil (annealed state) conducive to stamping

generally, the default delivery state of cold rolled coils is annealing state
