Abstract
The invention discloses a three-hole bicycle frame and a manufacturing method thereof. The three-hole bicycle frame is composed of an upper pipe, a lower pipe and a front pipe. The upper pipe and the lower pipe are connected with the front pipe. The three-hole bicycle frame is made of chrome-molybdenum steel pipes. A first hole horizontally and transversely penetrating through the center of the upper pipe is formed in the position, 60 mm away from the center of the front pipe, of the upper pipe, and the diameter of the first hole is 22 mm. A second hole horizontally and transversely penetrating through the center of the upper pipe is formed in the position, 100 mm away from the center of the front pipe, of the upper pipe, and the diameter of the second hole is 19 mm. A third hole horizontally and transversely penetrating through the center of the upper pipe is formed in the position, 135 mm away from the center of the front pipe, of the upper pipe, and the diameter of the third hole is 16 mm. The manufacturing method comprises the steps that the pipes with the diameters and the wall thicknesses being equal to the diameters and the wall thicknesses of the corresponding holes are used to be welded to the corresponding holes, and welding is conducted through the purely manual copper brazing process. According to the three-hole bicycle frame and the manufacturing method thereof, the three holes of the bicycle frame are connected in an intersected mode, so that the strength of the steel pipes is greatly improved.
Description
Technical field
The present invention relates to bicycle art, more specifically, relate to a kind of three hole cycle frames.
Background technology
Along with popularizing of electric bicycle, traditional bicycle is the most no longer people's walking-replacing tools first,
The life of people but traditional bicycle does not fade out, traditional bicycle as a kind of exercise,
The instrument of athletic competition and occur in the life of people.Either exercise or athletic competition use
Bicycle, all weight and intensity to vehicle body has higher requirement, i.e. requires lightweight desired strength again
High.
Summary of the invention
The technical problem to be solved is, overcomes the deficiencies in the prior art, it is provided that Yi Zhongsan
Hole cycle frame.
The present invention three hole cycle frame, is achieved by following technical proposals, and vehicle frame is by upper pipe, down tube
Forming with front pipe, top tube and down tube are connected with front pipe respectively, it is characterized in that, described vehicle frame uses chrome molybdenum steel pipe
Tubing, described upper pipe arranges level at front tube hub 60mm and passes across a diameter of 22mm of upper tube hub
The first hole, described upper pipe arranges level at front tube hub 100mm and passes across a diameter of of upper tube hub
Second hole of 19mm, described upper pipe arranges level at front tube hub 135mm and passes across the straight of upper tube hub
Footpath is the 3rd hole of 16mm.
The manufacture method of the present invention three hole cycle frame, first make a call on top tube the first hole,
Two holes and the 3rd hole, described upper pipe arranges level at front tube hub 60mm and passes across the straight of upper tube hub
Footpath is first hole of 22mm, and described upper pipe arranges level at front tube hub 100mm and passes across upper tube hub
Second hole of a diameter of 19mm, described upper pipe arranges level at front tube hub 135mm and passes across upper pipe
3rd hole of a diameter of 16mm at center, then uses the tubing that waits wall thickness isometrical with above-mentioned respective aperture to divide
Do not weld with described respective aperture, use pure manual brazing technique to weld.
Compared with prior art, the invention has the beneficial effects as follows:
The production technology of vehicle frame of the present invention has rewritten the most traditional vehicle frame production technology and theory.The present invention
The intersection in vehicle frame three hole is connected, and substantially increases the intensity of steel pipe.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that herein
Described specific embodiment, only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, the present invention three hole cycle frame, it is achieved by following technical proposals, vehicle frame
Being made up of upper pipe 1, down tube 2 and front pipe 3, top tube and down tube are connected with front pipe respectively, and described vehicle frame uses
Chrome molybdenum steel pipe tubing, described upper pipe arranges level at front tube hub 60mm and passes across the straight of upper tube hub
Footpath is first hole of 22mm, and described upper pipe arranges level at front tube hub 100mm and passes across upper tube hub
Second hole of a diameter of 19mm, described upper pipe arranges level at front tube hub 135mm and passes across upper pipe
3rd hole of a diameter of 16mm at center.
The manufacture method of the present invention three hole cycle frame, first make a call on top tube the first hole,
Two holes and the 3rd hole, described upper pipe arranges level at front tube hub 60mm and passes across the straight of upper tube hub
Footpath is first hole of 22mm, and described upper pipe arranges level at front tube hub 100mm and passes across upper tube hub
Second hole of a diameter of 19mm, described upper pipe arranges level at front tube hub 135mm and passes across upper pipe
3rd hole of a diameter of 16mm at center, then uses the tubing that waits wall thickness isometrical with above-mentioned respective aperture to divide
Do not weld with described respective aperture, use pure manual brazing technique to weld.
Because the wall thickness of chrome-molybdenum steel steel pipe used is at about 0.7mm, tube wall ratio is relatively thin, so this vehicle frame
The lightest.Plus the technique of pure manual brazing, the most elegant in appearance.
The above is only the preferred embodiment of the present invention, it is noted that for the art
For those of ordinary skill, under the premise without departing from the principles of the invention, it is also possible to make some improvement and profit
Decorations, these improvements and modifications also should be regarded as protection scope of the present invention.
