INSTRUCTION DESCRIPTION (i) Technical Field of the Invention The present invention relates to a method for manufacturing a handle riser, and more particularly to a process of cold forging and integral molding, in combination with extrusion, which is formed. The handle riser, in addition to having better strength and a variety of variable profiles, can also increase the contact area with the handles to make the combination between the two more stable. [Prior Art] The bicycle is the most environmentally-friendly vehicle. It has no air pollution, no noise, and no space. It is also the most convenient means of transportation. It does not require fuel, can be carried away, and has both sports and fitness effects. Bicycles have been researched and developed for more than two hundred years. They have not been eliminated, and their use has expanded from traditional means of transportation to competition, sports and leisure functions. Bicycle sports are now very popular in Europe and the United States, especially the emergence of mountain bikes, so that bicycles show a new look, so the upgraded bicycle has become a collection of many people. The bicycle mainly uses a simple frame as the connection of the various parts, the transmission of the force and the weight of the supporter. Therefore, the strength and rigidity are the main requirements of the frame. The high strength can avoid the breakage of the ride. Safety concerns, good rigidity can have better power conductivity; in addition, the frame needs to be lighter, and it can be more labor-saving and faster when riding; in general, the commonly used frame material is Shao alloy, carbon fiber, There are four types of titanium alloys and alloy steels, which are also frame materials that meet the above requirements. The handle riser is part of the bicycle frame, also known as the rider vertical

Description of the invention (2), mainly because the connection is due to the rider's center of gravity and arm support, and the requirements for the front insertion position are higher; In the case of closed forging and alloying steel, the product is improved. The general processing of this part is the shape of metal-resistant, double-forged, forged, cold forging, the handle and the front fork buckle. When riding a bicycle, its posture moves forward, its upper body and head, so the upper body All parts are transmitted to the front wheel, and then the power that is common in the official position, that is, the more mechanical manufacturing method, the better choice, the main process, can produce the characteristics of density fatigue; the current Dynamic forging, composite forging, forging, swaging, powder, constant temperature, constant temperature forging, processing, warmer, reduced deformation resistance, and can be used to control the riding direction; the potential is the sitting position of the upper body leaning forward The weight must be applied to the handle and the riser by the weight of both hands. Therefore, it is necessary to set the vegetable blue for the strong placement of these parts. To obtain better strength and rigidity is to use high pressure to extrude the material with high material, and the precision forging technology can be divided into cold/warm/heat precision forging and forging, casting and forging integration, micro and other technologies; The processing of the forging between the heat is more difficult to forge in the past. [Inventive content] Recently, there is a third manufacturing technology, which is another level of forging process, which can forge both internal and external materials. Especially in the process, the external pressure can maintain the integrity of the inside and outside of the material, and the processed products produced will be stronger than the general forging. Such a technique is disclosed in the invention patent of the domestic patent No. 9 1 1 0 4 5 6 3 1
