Abstract
The utility model provides a titanium alloy handlebar, which comprises a central part, a first end part positioned at the central part and extended to one side, and a second end part positioned at the central part and extended to another side, wherein the central part, the first and the second end parts form an integral tubular element, and are not positioned on a same central axis. The titanium alloy handlebar firstly selects titanium alloy pipe blank to prepare the blanking, and simultaneously debugs a machine installed with a mould; secondly, the selected titanium alloy pipe blank is placed into the cavity of the mould, and the mould is closed; then oil pressure is exerted on the inside of a titanium alloy pipe, so the titanium alloy pipe can deform according to the cavity of the mould; and finally, the pressure is removed, then the mould is opened, and a formed product can be taken out. The utility model solves the technical problems that the produced product is difficult to satisfy the requirements and the product quality is unstable due to the bad plasticity of the existing titanium alloy. The utility model has the advantages of stable product quality and the like.
Description
Technical field
The present invention relates to bicycle assembly parts, be specifically related to a kind of titanium alloy handlebar.
Background technology
Because the plasticity of titanium alloy is a lot of with respect to other material difference, be difficult to the picture aluminum alloy, chrome manganese steel is made the handlebar of a lot of patterns like that; Though utilize traditional processing technology can process needed shape, the product that processes is difficult to satisfy processing request, product design is also unstable, thus make the product made without any value of service and market outlook.
Summary of the invention
Poor in order to solve existing titanium alloy because of plasticity, make the product that processes be difficult to meet the demands and the also unsettled technical matters of product design, the invention provides a kind of titanium alloy handlebar.
Technical scheme of the present invention is as follows:
A kind of titanium alloy handlebar comprises core, is positioned at the first end that core extends to a side; And the second end that is positioned at core to the opposite side extension; Described core forms a single-piece tubular member with first end and the second end; Above-mentioned core and first end and the second end be not on same center shaft.
Above-mentioned first end is identical with the caliber of the second end; The caliber of described core is greater than the caliber of first end and the second end.
Form the angle of 2.5-3.5 degree between above-mentioned first end and the second end and the core.
The caliber of above-mentioned core is first end and the second end caliber 1.4-1.5 a times.
Above-mentioned core by base pipe and with base pipe be that the Taper Pipe of one is formed; The bore of the awl mouth of described Taper Pipe is identical with the caliber of first end and the second end; The length of described core is 2-3 times of base pipe length.
The length of above-mentioned handlebar is the 2.5-3 multiple of core.
Above-mentioned core, first end, and the second end is to adopt titanium alloy to make.
Implement titanium alloy handlebar of the present invention and have following beneficial effect:
Method by the machining titanium alloy handlebar makes the titanium alloy handlebar as the carbon fibre aluminum alloy, and chrome manganese steel has equally been realized the diversification of product.Titanium alloy blank pipe is put into the mold cavity that performs, utilize oil pressure that titanium alloy tube is expanded, thereby carried out the reducing variation of outer reducing handlebar, make the titanium alloy reducing handlebar of making reach whole requirements, and constant product quality.
Description of drawings
Fig. 1 is the preceding structural representation of handlebar processing of the present invention;
The structural representation of Fig. 2 after for handlebar of the present invention processing.
Description of reference numerals:
Core 1, base pipe 101, Taper Pipe 102, awl mouth 112; First end 2; The second end 3.
The specific embodiment:
Referring to Fig. 1 and shown in Figure 2, titanium alloy handlebar provided by the invention comprises core 1, is positioned at the first end 2 that core extends to a side; And the second end 3 that is positioned at core 1 to the opposite side extension; Core 1 forms a single-piece tubular member with first end 2 and the second end 3.Core 1 and first end 2 and the second end 3 be not on same center shaft.First end 2 is identical with the caliber of the second end 3; The caliber of core 1 is greater than the caliber of first end and the second end; The caliber of core 1 is first end 2 or the second end 3 calibers 1.4-1.5 a times.Can form the angle of 2.5-3.5 degree between first end 2 and the second end 3 and the core 1.Core 1 is formed for the Taper Pipe 102 of one by base pipe 101 with base pipe 101; The length of core 1 is 2-3 times of base pipe 101 length, and the bore of the awl mouth 112 of Taper Pipe 102 is identical with the caliber of first end 2 and the second end 3; The length of handlebar is the 2.5-3 multiple of core 1.Whole handle bar all is to adopt titanium alloy to make.
The present invention at first by selecting the titanium alloy tube blank to prepare blanking, debugs the board of installation mold simultaneously; Secondly the titanium alloy tube blank of choosing is put into the die cavity of mould, and close up mould; Once more oil pressure is put on the inside of titanium alloy tube, make the die cavity generation alteration of form of titanium alloy tube by mould; Remove behind the pressure product that moulding is taken out in die sinking more at last.
