SETAP series octagonal crushing fine screen is the latest crushing and sieving technology developed by the author. A new type of crushing fine fine screen developed according to European standards has been ordered by customers and put into production by our company. The equipment integrates crushing, coarse screening and fine screening into one, and integrates the functions of hexagonal fine screen and drum crushing screen. The old sand can be fully screened after entering the equipment, and the real waste is removed, which is beneficial to the foundry. The purification and recycling of sand greatly improves the utilization rate of old sand and reduces the production cost.
SETAP series octagonal crushing fine screen is mainly composed of sieve cylinder, frame and transmission system. The screen cylinder has an octagonal shape, and the screen mesh is tightly fixed on the octagonal screen cylinder. When the screen cylinder rotates, it has better projectile and rebound effects, which is beneficial to the crushing and sifting of the old sand; the sieve cylinder is divided into three levels. The first stage is crushed, the second stage is coarse screen, the third stage is fine screen; the screen mesh is made of special steel wire, which is not only easy to stick sand, but also has better crushing and screening effect; the transmission system does not use the common cycloidal pin gear reducer and The sprocket transmits power, and the parallel shaft helical gear reducer directly drives the main shaft. Therefore, the machine has the characteristics of simple structure, large screen area, high production efficiency, fine screening, stable and reliable operation, and is suitable for the foundry old sand. Purification and recycling.
Mainly engaged in mechanical design and mechanical manufacturing work. Similarly, the tool magazine is arranged around the main shaft. However, with each robot using one robot, there is almost no time loss for the tool change, and any knife selection method can be adopted. For example, the machining center of FZ08S and FZ08W produced by CHIRON of Germany has its tool magazine arranged around the machining spindle and can move with the spindle, and each knife has one set of robots. Its knife-to-knife tool change time is only required. 5s, and the chip-to-chip change time is 1.5s. (5) When the tool changer driven by the cam linkage realizes the movement and position required by the design, the cam mechanism can not only accurately control, but also have good dynamic characteristics. Therefore, the tool changer driven by the cam linkage can operate reliably under high speed conditions. Therefore, the automatic tool changer with a short tool change time is generally a tool changer driven by cam linkage.
The rapid automatic tool changer adopts the HSK hollow short taper shank shank, which is a development trend. Because the HSK shank is light in weight and the pull-out knives have a short stroke, it can naturally speed up the tool change speed of the automatic tool changer.
