example 1

[0079] A rod with a core and a woven fabric made of synthetic fibers are placed in the mould. The mold was filled with unvulcanized NBR and subsequently vulcanized. As a result, get as figure 1 Shown is a wiper 1 comprising a cored rod 3 and a wiper body 10 . The lip 11 of the wiper body 10 is covered with the organic fabric 5 .

[0080] Use wiper 1 and measure pressure, sliding resistance, and amount of spilled debris. The results are shown in Table 1.

[0087] The cored rod and the woven fabric made of synthetic fibers (nylon 6,6) are placed in a mold filled with unvulcanized NBR and subsequently vulcanized. As a result, get as Figure 10 Shown is a wiper 1 comprising a cored rod 3 and a wiper body 10 . The sliding surface of the lip 11 of the wiper body 10 is covered with the organic fabric 5 .

[0088] The woven fabric used has a thickness of 0.5 mm (measured on the original fabric). The weft yarn of the woven fabric has a fineness of 100 denier and the warp yarn of the woven fabric has a fineness of 50 denier. The woven fabric is arranged on the lower surface of the lip so that the weft yarns are arranged perpendicular to the sliding direction.

[0089] This wiper was used, and its frictional resistance was measured under the following conditions.

[0101] The thickness of the fabric material (the original fabric to be used for the fabric layer) was 1.0 mm, and the weft yarn of the fabric material had a fineness of 420 denier, and the warp yarn of the fabric material had a fineness of 210 denier. In other respects, the wiper of Example 3 is the same as that of Example 2. The frictional resistance of the wiper of Example 3 was measured.

[0102] As a result, the distance over which the wiper was operated until abnormal noise was generated was 2000 km.

Abstract

A wiper for machine tool small in abrasion resistance and abrasion loss at a lip part, comprising a mounting part (3) installed on a machine tool moving relative to a sliding surface (14) and a wiper main body (10) which is formed integrally with the mounting part (3) and made of an elastic material, wherein a lip part (11) of the wiper main body (10) can be slid on the sliding surface (14), and at least the lip part (11) of the wiper main body (10) is covered with fabric material (5), whereby the wiper for machine tool is prevented from being damaged by the collision or impact of chips and the sliding surfaces thereof is prevented from being damaged.

Description

technical field [0001] The present invention relates to a wiper for machine tools that works on the sliding surfaces of machine tools and industrial equipment to wipe off chips, cutting lubricants, etc. Cutting lubricant enters sliding surfaces. Background technique [0002] Traditionally, wipers for removing debris and cutting lubricants from machine tools include a lip with a sliding portion, typically of rubber material. The reason for adopting the rubber material is to utilize its elasticity to improve the tracking and scraping ability of the wiper in all directions. [0003] Recently, equipment systems, high-speed type machine tools, etc. that do not use cutting lubricants (dry cutting) to avoid environmental problems have been developed. With these devices in particular, the adherence of the sliding part of the wiper to the sliding surface cannot be maintained for a long time due to the high coefficient of friction of the rubber and the slidi...
