Abstract

This design is an improved PRESS to make CHAIN GUIDE BAR for ship engines easier, faster and safer.It is equipped with three different molds fixed in one PRESS to prevent human loss of lifting the upper mold by hand for product extraction. Reduced, three different products can be produced in one press operation.
Furthermore, by inserting various molds into each mold, it is possible to produce products of different sizes in a single mold, and it is possible to take out products more easily by equipping the lower mold with SPRING for product extraction. At the same time, the number of defective products due to the occurrence of GAS was significantly reduced.
Increasing productivity and manual risk, which is the ultimate goal, can be prevented in advance, resulting in "maximization of the speed of work under safety first".

Description

    Hydraulic press for chain guide bar production {MANUFACTURING HYDRAULIC PRESS FOR CHAIN GUIDE BAR}

This invention is designed for manufacturing chain guide bar. One press is installed in one press machine, and then one finished product is manufactured. Compared to the existing production method, man hour (M / H, Man Hour, karate, number of water: 1 hour It is a press machine that has been improved / manufactured to prevent the risk of time loss and safety accidents due to the increase in the amount of work performed by a single worker) and the ILO margin ratio due to the manual mold replacement method. One matter is described below.

  Conventional CHAIN GUIDE BAR manufacturing did not contribute to the company's sales profit due to excessive monetary and time loss by full operation of equipment to meet the sluggish productivity and delivery volume and delivery due to manual mold replacement and 1 CAVITY production.

In other words, preliminary work that needs to be done due to frequent mold changes due to the production of small quantity batches-eliminates the risks of unreasonable factors in production and mold replacement, such as time loss due to preheating and product productivity degradation due to the disassembly of mold during product take-out. I tried to

  The present invention is designed / modified to produce multiple sizes of products in one operation by manufacturing / installing multiple molds in one press unit without replacing the mold in one press machine. Other sizes of products are produced even during mold inspection / repair. This is possible so the purpose is to reduce the LOSS due to the equipment.

Therefore, in the present invention, by fixing the GUIDE BAR mold of a new configuration that can eliminate the problems occurring when replacing the mold in the existing press as described above (integrating the upper / lower plate and the upper / lower plate of the press) This design has been completed with the technical task of designing to integrate all kinds of GUIDE BAR produced by our company in the fixed mold so that it can work without mold replacement.

The present invention can produce several products in one operation, which can generate time and financial benefits, and can also prevent accidents caused by mold replacement.

5 is a finished product GUIDE BAR for ship engine manufactured by our company.

  The present invention will now be described in detail with reference to the accompanying drawings. To list, push 8,9 (upper and lower mold) into our standard work method 6,7 (upper and lower heater plate), produce one product, and then manually lift 8 (upper mold) and take out the product. Although the upper mold) was manually lifted and closed, the current working method is 6,7 (upper and lower heater plate), and three molds having the same length but different widths are placed on 6,7 (upper and lower heater plate). 3 types of different lengths and widths in one operation

Products can be manufactured, and further, by using different types of frameworks, more products can be produced. In addition, it is no longer necessary to lift 8 (upper mold) by hand when taking out, and the process of disassembling some parts of 9 (lower mold) to remove the finished product is omitted boldly. High rigidity and high elasticity SPRING were inserted and manufactured to reduce the time loss for removal. This manufacturing method helps the easy removal of the product, but it has a structure that can easily discharge the GAS generated when the rubber is melted due to the characteristics of our product GUIDE BAR, which has resulted in a significant defect reduction.

  In addition, various types of molds were inserted into three types of 9 (lower molds), so that products having the same width but different lengths could be manufactured in one mold. For example, if you work with a mold of 185 * 50.8mm (length * width) in a mold that produces a product of 1,000 * 50.8mm (length * width), it will be 815 * 50.8mm (length * width). It is possible to produce various products with different sizes from 3 types of 8,9 (upper and lower molds) of the same length but different widths as if the product is completed. The risk of replacement is greatly reduced.

Claims (4)

    The upper mold is bolted to the upper heater plate and fixed so that the upper mold also rises when the press is raised, making it easy to take out the product.        The method of claim 1, wherein a high rigidity, high elastic spring is inserted into the lower mold for easier product extraction.       By inserting the mold in the lower mold, it is possible to produce various products of different sizes in one mold. Three molds are installed in one press to improve productivity three times compared to the previous one and use 1/3 of the electricity to reduce the cost and install three separate molds. In the case of one mold repair, the two molds can still work, reducing the productivity loss due to the mold repair.
