Description

The shaft road that is used for heald frame

Technical field

The present invention relates to a kind of shaft road that is applicable to the heald frame structure.

Background technology

Owing to the loom speed that improves day by day and the loom fabric width of increase, the stress that heald frame is increased.Therefore, on the one hand, morning, existing people's trial to reduce the stress that heald frame bears, on the other hand, increased the rigidity of heald frame by the quality of minimizing motion thing.Yet, consider growing cost pressure, must recognize but the complicated technology scheme no longer suitable.

DE2933442C2 discloses a kind of shaft road, has the profile of hollow box shape, is made by synthetic material or light metal.If this profile is made of aluminum, then can be heavier.On the contrary, if produce with fibre-reinforced synthetic material, then production technology is understood more complicated, and cost is also higher.

Except the box-like profile, also there is file to mention the use of I word profile.For example AT180240C discloses a kind of shaft road of sheet metal profile, and wherein the edge of strip metal sheet profile is turned up to produce fillet.And the band between the fillet disposes for example wrinkle of longitudinal extension.Similarly, CH286827C discloses the shaft road of pleating sheet metal profile.FR1009932C and CH276383C disclose the shaft road with I tee section.Japanese Utility Model 60-36616U discloses the shaft road with I ellbeam, and wherein the I shape at center comprises thicker fillet and than the center band of thin-walled.This band must dispose packing material and hardened material in both sides.Fillet is connected with each other by outer cover.In fact, these carry cover has together increased rigidity, but has also increased overall weight greatly.

In view of this problem, the purpose of this invention is to provide a kind of shaft road, can satisfy the requirement of the high rigidity of low weight of increase, and allow simultaneously that complexity is low to form making of this saving.
