Abstract
The utility model discloses a thin wall cylinder used for supporting members or isolating sleeves for shaft and sleeve types of mechanical parts. The thin wall cylinder made of a thin sheet or sheet leftover material is punched, bent and rolled, wherein, butt edges are made into convex and concave rabbets or gaps and the heads of the rabbets are greater than tails while the bottoms of the gaps are greater than mouths; the rabbet at one side corresponds to the gap at the other side and both sides are engaged through the rabbets and the gaps. The utility model has the advantages of easy process, high productive efficiency, sheet leftover material availability, high material utilization rate, and low processing cost.
Description
The utility model relates to a kind of thin walled cylinder.The supporting member or the separation sleeve that can be used as axle sleeve class mechanical part.
At present, as the thin walled cylinder of axle sleeve class supporting member or separation sleeve, its processing method mainly contains two kinds: a kind of is to form through cutting with pipe; Another kind is after sheet material is rolled into cylinder, forms through welding, cutting again.These two kinds of methods all need could guarantee through cutting repeatedly the required precision of its inside and outside footpath and length, the processing comparison difficulty of getting up, and manufacturing efficiency is not high.Therefore, be only applicable to bigger single products, and be not suitable for production in enormous quantities.Especially the higher thin-walled axle sleeve of required precision, just more difficult realization.In addition, in above-mentioned two kinds of processing methods, the former needs steel pipe, and the latter then needs bulk sheet material, and leftover pieces can not utilize, and the utilization ratio of material is low, and processing cost is higher.
The purpose of this utility model is to provide a kind of thin walled cylinder, and this cylinder need not cut, and interface need not weld, and not only the manufacturing efficiency height can be produced in enormous quantities; And the utilization ratio height of material, can cut down finished cost greatly.
Above-mentioned purpose of the present utility model is realized by following technological scheme:
Thin walled cylinder of the present utility model is formed by the thin plate butt joint that twists, and it is protruding, recessed alternate tenon or gap to edge fit, and the head of tenon greater than the bottom of afterbody, gap greater than oral area; Wherein the gap of Yi Bian tenon and another side is corresponding, and both sides are interlocked by means of tenon and gap.
Because thin walled cylinder of the present utility model is twisted by cold stamping by thin plate and forms, and it is interlocked by tenon and gap to edge fit, therefore:
1. need not cut, weld, just can guarantee the required precision of inside and outside footpath and length, easily processing, the manufacturing efficiency height can be produced in enormous quantities;
2. can utilize leftover pieces to process, the utilization ratio height of material, processing cost is low.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is a thin walled cylinder schematic representation of the present utility model;
Fig. 2 is the deployed condition schematic representation of Fig. 1.
As depicted in figs. 1 and 2, earlier with the sheet material or the sheet material leftover pieces of desired thickness, adopt process for stamping and forming to twist into cylinder, it strikes out protruding, recessed alternate tenon and gap to edge fit, and make the tenon head greater than its afterbody, gap bottom greater than its oral area.Wherein the gap of Yi Bian tenon and another side is corresponding, and both sides are interlocked by tenon and gap.
Claims (1)
- Thin walled cylinder is characterized in that this thin walled cylinder is formed by the thin plate butt joint that twists, and it is protruding, recessed alternate tenon or gap to edge fit, and the head of tenon greater than the bottom of afterbody, gap greater than oral area; Wherein the gap of Yi Bian tenon and another side is corresponding, and both sides are interlocked by means of tenon and gap.
