JPS5825830A - Metallic wire cushion body - Google Patents

Abstract

PURPOSE:To obtain a good metallic wire cushion body by making parts in which inorganic fibers are disposed freely at every several meshes in circumferential direction and at a fixed interval in axial direction, and parts devoid of inorganic fibers when knitting a metallic wire, and covering by winding only with the metallic wire at the last of bag wrapping. CONSTITUTION:When knitting a metallic wire 1, about 0.15phimm. in diameter, inorganic fiber 2, about 0.3phimm. in diameter, is so knitted uniformly that three meshes in circumferential direction are made free and succeeding three meshes are passed through at an interval of, for instance, three meshes to form a metallic wire net cylinder 3 containing inorganic fibers. In forming the metallic wire net cylinder 3, inorganic fibers 2 are knitted in a part (a) from an end to the middle part of the metallic wire net cylinder 3, and inorganic fibers 2 are not knitted in a part (b) from the middle part to another end. The wire net cylinder 3 is bag wrapped from the part (a). After covering by winding finally in the part (b), it is formed by compression to specified form to obtain a metallic wire cushion body.

Description

[Detailed Description of the Invention] This relates to a heat-resistant metal wire cushion body for elastically supporting objects, etc., and its purpose is to use a metal wire of sufficient thickness and oxidation resistance to achieve the same effect as using thin wire. The purpose is to improve the load-deflection characteristics so that the honeycomb catalyst body etc. can be elastically supported without being easily broken.

Conventional metal wire cushion bodies have had the disadvantage that when the metal wire is made thinner to improve sealing performance, oxidation resistance decreases and the metal wire becomes oxidized by exhaust gas and falls apart. For this reason, it was considered to knit inorganic fibers such as asbestos fibers together with metal wires, but since the knitting involves hooking and pulling with needles during knitting, the weak inorganic fibers easily break and could not be put to practical use. Therefore, instead of weaving inorganic fibers, we wrap them helically around the outer circumference of a wire mesh tube, or wrap multiple pieces in a ring shape.
Next, it was rolled up into a bag and compression molded into a predetermined shape, but since it was not knitted, the inorganic fibers tended to move easily and could not be rolled up uniformly.

In the present invention, when circularly knitting metal wire, the inorganic fibers are freed for several stitches in the circumferential direction at regular intervals in the axial direction, and then knitted so as to pass through the stitches and lock them. A wire mesh tube containing inorganic fibers is wrapped in a bag from one end to prevent the fibers from being woven into it, and the surface of the bag roll is wrapped with a wire mesh tube made of only metal wire, and the inorganic fibers are exposed on the surface with a compression-molded metal wire mesh tube. Make sure not to
The inorganic fibers are uniformly distributed within the metal wire cushion body, thereby eliminating the drawbacks of the conventional cushion.

Fig. 1 is a partially enlarged view showing an embodiment of an inorganic threaded metal wire knitted wire mesh tube used in the present invention, and ■ indicates a diameter of 0.
．． It is circularly knitted with metal wire such as 15φ dark stainless steel wire. 2 is an inorganic wire made of asbestos wire, glass wire, etc. with a diameter of 0.8φ, and when knitting metal wire l in stockinette circular knitting, 3 stitches are spaced in the axial direction, 3 stitches are free in the circumferential direction, and then 8 stitches are made. It is woven into the stitches of stockinette knitting so that it locks into place. Various methods of knitting can be considered, but the detailed explanation will be omitted as the specific means is outside the scope of the present invention, but when knitting, the inorganic fibers are locked through the stitches, so the inorganic fibers 2 may be cut. It is knitted evenly without any scratches. If the wire mesh tube 3 containing inorganic fibers is wrapped in a bag and compression molded, the inorganic fibers 2 will rise to the surface and will easily break, and the inorganic fibers 2 will be free for a relatively long time at the broken places, so exhaust air will be removed. It has the disadvantage that it is blown away by gas, making the inorganic fiber non-uniform and causing poor load-deflection characteristics.

The present invention is designed to eliminate such drawbacks, and the eighth aspect of the present invention is to
As shown in the figure, inorganic fibers are woven in the 0 part from one end to the middle part of the wire mesh cylinder 4 made of knitted circular knitted metal wire, and inorganic fibers are not woven in the 6 parts from the middle part to the other part, As shown in FIG. 8, one end is wrapped in a bag to form a bag-wrapped body 5, and finally six parts are wrapped in a bag and compression-molded into predetermined shapes as shown in FIGS. 4 to 6 to form metal wire cushion bodies 6 of various shapes. , 7.8.

According to the present invention, several stitches of inorganic fibers are made free in the same direction, and then the inorganic fibers are woven through the stitches so as to be locked, so that the inorganic fibers are difficult to break, and no inorganic fibers appear on the surface of the compression-molded metal wire cushion body. Therefore, the inorganic fibers are not blown away by the exhaust gas, and the inorganic fibers are evenly mixed inside, so the load-deflection characteristics are stable as shown in Figure 7, and the load due to increased deflection is reduced compared to the conventional product. The degree of increase is small, and therefore, even if there are variations in the external dimensions of the honeycomb catalyst body, the honeycomb catalyst body is characterized in that it is difficult to break when assembled into a case.
