The guide post is a guide element used in the mold and the assembly to ensure that the mold guides the stroke of the mold with a precise positioning. The material of the guide pillar is generally selected from bearing steel, hot die steel, and easy-car iron. The use of bearing steel SUJ2 is relatively large, so that the durability and interchangeability of the guide pillar in guiding performance are greatly enhanced. The guide pillars and components form an outer guide pillar assembly and an inner guide pillar assembly with a beautiful metallic luster. Guide column heat treatment: HRC58-62; guide column surface roughness: Ra0.8, Ra1.6 The guide posts are generally cylindrical with shoulders, and generally have oil grooves. The number of oil grooves increases as the length of the guide columns increases, and the maximum number of oil grooves is generally eight. Calculation of the Length of C Segment of Inclined Column The length of the C section of the inclined guide column is very important. Its length controls the distance S that the slider runs. The calculation of the length of the oblique guide column is actually using the "trigonometric function". We can simplify it into a triangle to facilitate the use of "trigonometric" calculations. The setting S is the slider sliding distance S in the figure, and the angle X is the angle D in the figure. (These two numbers have been set to fixed values ​​according to the needs of the product and mold design and are known numbers.) The length L is relative to C in the above figure. Height H is the distance that the mold opens when the slider slides to the specified position. The values ​​thus calculated are only in an idealized state, and actually the gap between the slider and the inclined column, and the roundness above them, must be taken into consideration. However, computer-aided design software such as AutoCAD is now so advanced that it completely liberates people from the complicated calculation formulas. As long as some simple commands are used or some faster ones are used, the required obliqueness can be drawn. The pillars, which can also be used to derive their length, can also simulate their state after the mold has been opened. No manual calculation of these data. Determining the Angle of Inclined Column in Mold The angle of the inclined guide column of the mold is usually 20 degrees or 25 degrees. Generally, the angle is 20 degrees. If the distance moved by the slider is a bit long, 25 degrees can be used. If the distance is longer, use hydraulic or pneumatic methods. The function of the center hole of the guide column The roundness of the guide post is very demanding, and the center hole is mainly used to grind the outer diameter by using a cylindrical grinding machine, because when using the cylindrical grinding machine to grind the outer diameter, the guide column must be rotated by the top against the center hole. Can be ground.
India, Asia and the Middle East
Tokyo, August 21, 2017 --- Hitachi, Ltd. (TSE: 6501, [Hitachi") and Hitachi Building Systems Co., Ltd. today announced the launch of the new TX Series escalator for India, Asia and the Middle East. The escalator has already been released in China*1, and will be released in stages across the remainder regions, commencing August 21, 2017.
In July 2016, Hitachi integrated its escalator businesses of Japan and China, consolidating its resources and enhancing its business operations in both countries, centered around its key business location in Guangzhou, China. The new TX Series escalator launched by Hitachi is a model that meets multiple standards in China, India, Asia and the Middle East. The model follows the same concept for the machine room-less elevator for Asia and the Middle East which was launched in September 2016. In addition to conforming to Chinese safety and quality standards for escalator equipment, the TX Series will be manufactured in accordance with Hitachi's own strict standards of safety and quality, adhering to safety standards in all other regions. It also adopts a functional design based on the concept of an escalator that fits closely with the unconscious actions of users, in the pursuit of their ease and comfort.
The TX Series offers flexibility with a selection of various product specifications, as well as its excellent design and safety features, designed to cater to a diverse range of customer needs. It also saves space required for the installation, covering a smaller area in comparison with existing products*2.
Hitachi will begin sales of the TX Series in Thailand, followed by launches in the Philippines, Malaysia and various other regions, and aims to receive orders of 10,000 units in 2018 in China, India, Asia and the Middle East.

Hitachi Launches New TX Series Escalator for
Features of the TX Series
The TX Series offers various new safety features designed with optimal user safety in mind. The side portions of the steps are 8 mm higher than the central portion to prevent accidents in which a users' shoe can become caught between the step and the skirt (side wall) of the escalator. The new TX series has also been fitted with brushes located at foot level on the left and right skirts to let users know if their foot comes into contact with the side walls. A special finish has also been adopted for the landing plates at the entry and exit points of the escalator to prevent users from slipping when getting on and off the escalator.
The TX Series adopts a simple and functional design that offers the smoothness, safety and comfort that users unconsciously expect to experience when riding an escalator. For example, by minimizing the size of the metal frame supporting the escalator's balustrades, the TX Series' design maximizes the size of the glass surfaces, and achieves greater simplicity at the entrance and exit points (landings) by reducing the number of recesses and protrusions around the hand rail. Additionally, by expanding the installation space of the light fixture, the TX Series also enables enhanced lighting options for illuminating the entire surroundings of the balustrades.
By shortening the span dimensions*3 by 150 mm, the TX Series has made it possible to install escalators in more confined spaces where installation presents difficulties with conventional product designs.
