Chen Yuhui, manager of Kaimde Machinery Co., Ltd.
Guangdong Foshan Kemde Machinery Co., Ltd. is a Hong Kong-owned enterprise, mainly producing and selling cam indexing institutions. It is the first foreign-invested enterprise in China that uses imported processing centers to produce high-speed precision intermittent splitters.
The introduction of Hong Kong's advanced management model, with strong technical force, advanced process requirements, professional processing equipment, and sophisticated testing methods, has become the leading enterprise of domestic cam indexing institutions, and challenges the market leading position of imported brands with pure domestic products.
Chen Yuhui, general manager of Kemde Machinery, is young and promising. He is a computer professional. He has simulated the actual movement and efficiency of all the parts produced by Kemd. He pointed out that the technology for manufacturing cams in China is still quite different from the international advanced level. Therefore, he has hired several experts from Canada and Taiwan to assist in the development of a cam indexing mechanism production system suitable for customers. Mr. Chen believes that the cam indexing mechanism is actually an automatic equipment. Compared with the previous pneumatic indexing mechanism, the precision is high and the noise is small. Now, the products of Kaimde can precisely guarantee the position of the stop, and the error is controlled at 0.01. Within mm, this is closely related to the precision parts manufactured by Haas machine tools.
Simple design and precision
General Manager Chen said that the cam indexing mechanism produced by Chemde Machinery is mainly a simple mechanism consisting of cam and output shaft grouping. It can provide a wide variety of intermittent movements without any unnecessary parts. When the motion is stopped, the roller is precisely fixed at the set position without any locking components.
The principle of the splitter structure is that the indexing cam mounted in the input shaft is connected with the output turret, and the cam rollers are radially embedded in the circumferential surface of the output turret, and the taper support ribs of the cam are in linear contact with their corresponding inclined faces. When the input shaft is rotated, the cam roller rotates the output turret according to the displacement curve on the cam, and at the same time rolls along the inclined surface of the rib, in the region where the rib and the end face of the cam are balanced, that is, in the static range, the roller Kay Mund:
The shaft is turned on, but the output tower itself does not rotate. The taper support ribs are simultaneously in contact with two or more rollers so that the rotation of the input shaft can be uniformly transmitted to the output shaft, thereby producing smooth and smooth intermittent motion.
Haas machine tools are highly praised
Kemde has more than 20 professional equipments for drilling, milling and grinding, including the 50-taper vertical machining center VF-3YT-50 with Haas plus 4th axis and extended Y-axis table, and horizontal machining center. The EC-300 provides an excellent guarantee for machining accuracy. According to Mr. Chen, Chemde is currently processing 24 hours a day, every Saturday, and on the seventh day, necessary maintenance is required to keep the Haas machine at its best. In addition to the problems that have arisen since the beginning of the gas source instability, there are almost no problems in the future. Mr. Chen pointed out from the expert's point of view that Haas machine tools are quite realistic from design to manufacture, with high speed, high precision and stability. Good sex, coupled with the price is particularly affordable in imported machine tools, as well as timely service, adequate spare parts, and controllers are designed and manufactured by Haas, which is difficult for other machine tools. Mr. Chen said that if a machine tool is not stable enough, it may take three to forty hours for them to process a part. In the event of a machine tool failure during the process, the loss is enormous. Therefore, Mr. Chen decided to choose Haas machine tools.
At present, Chemde has produced more than 10,000 sets of cam indexing institutions a year, with an annual growth rate of 20% to 30%, and the demand is still increasing. Mr. Chen pointed out that the high-level application of the cam indexing mechanism is actually the most basic automated production. In the future, the company will move toward the more effective application of the cam indexing mechanism, from the production of the cam indexing mechanism, to the planning and design for customers. Automated production system.
