JPS6213819A - Fluororesin plate for sliding surface with oil sump - Google Patents

Abstract

PURPOSE:To form a fluororesin plate for a sliding surface with a crucible with good accuracy by forming a cavity left behind as an oil sump on the surface of a plate carbon fluoride polymer and the smoothing the surface. CONSTITUTION:A cavity which is left behind as an oil sump after smoothing is formed on the surface of a plate carbon fluoride polymer, and after that, the whole periphery of the inner wall surface of the cavity is chamfered like a circular arc so that at the time of smoothing, burr is not caused at the surface of the plate. Lastly the surface of the plate is smoothed, whereby a fluororesin plate for a sliding surface with an oil sump can be manufactured without a lowering of smoothness.

Description

[Detailed Description of the Invention] This invention is based on Teflon [
On one plate, a Teflon material is molded and becomes an oil pool at the right time.
Creating a recess or 114 to enhance the lubrication function will eliminate or significantly reduce the time required for scraping in Jt2 during machine manufacturing.

In recent years, with the development of two-way machining machines, the sliding surface has been coated with Teff [! Nowadays, the use of digital boards has become popular. The reason is that conventional metal 1. The combination of metal and metal rollers gives Z-4 its very excellent characteristics. In other words, combinations of metals and I-lars had problems such as too high or too low coefficient of friction, stake slip, and vibration. In particular, in N/C machine tools, inertia control by +Rtrt of workpieces immersed in the table leads to accurate positioning, stopping +h, and vibration absorption. Teflon is slippery and has a low coefficient of friction due to its property of not bonding with the pond F, for example, about 1/10 of that of metal to metal, and about 10 times that of roller bearings to metal.

For this reason, it has an ideal friction coefficient for positioning and stopping machines, and since the dynamic friction coefficient and static friction coefficient are basically the same value, it has the characteristic of not causing stake-slip.

Now, if we follow the order of joining the Teflon plates, we can see that the Teflon plates, which have been pressed and dried using epoxy resin on each sliding surface, are machined into 7 rice cutters in one line or at right angles to the reference plane. Alternatively, it may be polished for accuracy, and then scraped during assembly.

Disadvantages of the conventional technology In scraping pressurization, the low parts scraped by the souffle bar become oil pools, and the high parts become smudges, but if you are not careful, the precision required to create the oil pools will increase. Because the scratched surface is scraped off using only the human senses using a scraper, the accuracy may be compromised, and the degree of this decrease increases as the area to be scraped increases.

Recently, due to advances in design and processing methods, there has been an increase in the number of machines that can be used as is without any precision correction after machining, as long as there is an oil reservoir. Also, even if there is some accuracy correction, it is often only a part of the surface. However, because up until now, materials with rough surfaces such as Teflon did not have uradamari, it took a long time to apply scraping. Therefore, the present invention solves this problem by creating grooves or depressions that become oil pools at the appropriate time during the manufacture of Teflon plates.

Example Now, taking a 1.2 mm back plate as an example, in the conventional method, it is cut by a machine (1: l tJ' 411 pools were created in the range of 1/100th to 2/100th of a millimeter.

The oil pool and Naro l/4, or Kuhomi, in this case have the following characteristics.

1. Even if the Oll is machined by about 0.2 mm, an I (shaped hole) is attached around the entire circumference so that no burrs will appear on the top surface of the Teflon plate.

2. The grooves and depressions can be half-shaped, oval-shaped, diamond-shaped, U-shaped, single-shaped, S? Various shapes, such as shapes, , are independent so that 411 does not flow out.

3. The depth of the grooves and depressions is set to a depth that does not interfere with the adhesion of the Teflon plate.

Function As described above, the Teflon plate with the oil pool of this invention is machined as it is, but at the initial wear stage, when the Teflon plate transfers to the side, it gradually becomes smooth, which is incomparable to the conventional plate. It has many deep oil pools, which prevents the oil from breaking and allows the machine to maintain its accuracy over a long period of time.

As a result, the time required for scraping can be reduced to zero, or significantly reduced, resulting in cost reductions, and as a synergistic effect, the Teflon temporary can be removed by polishing, and unlike conventional methods, a large number of oil pools can be created when the Teflon is removed. Because of this, it is also possible to prevent the adhesion phenomenon that occurs when the polished surfaces slide.
