Through the deep hole of the center, the deep hole provides a mandrel through the planting, and the shaft can be locked to the crank, so that it can provide bicycle pedaling. However, the die casting method has the following disadvantages: (1) Die-casting alloys are limited; currently there are only six types of aluminum. ^ Tin, Wrong, Copper, Magnesium, (2) Equipment is expensive: pressure clocks, swaying, and ships such as house castings can be used for mass production. Casting and other costs are quite expensive, and it is only internal (31 castings have poor air tightness: due to the high-temperature filling of the liquid to the die-casting mold: the part: = flow phenomenon 'local shape': (4) the pedal tube of the pedal is extremely easy (4) When the gas enters and there is an injection, the shaft tube and the step frame of the pedal are changed to plastic-body, which is wrong to reduce the cost. However, the resistance of the plastic molded foot wall plate 3 201041778 is not strong, and is easily damaged by the impact. Degrading the service life, the weight will be plagued by insufficient safety, so the plastic pedal is not common in the market. The inventors have in view of the fact that the current pedals have great problems regardless of the use of metal die-casting or plastic injection molding. Through careful testing and research, and an insatiable spirit of invention, the invention has been developed with practical effects. [Invention] The main content of the present invention is to provide a method for pedaling, which is mainly processed by cold-bending forming technology. a hollow step frame, and the tube seat is fixed to the step frame by welding so as to have a sufficient contact area to provide a mandrel frame, thereby manufacturing the step frame and the socket In a manner, the present invention can remove the disadvantages of metal die-casting or plastic injection molding pedals, and has the advantage of economical manufacturing in today's small and diverse market demand. The main content of the present invention is to provide a pedal The plate making method mainly uses a metal rolled pipe or an aluminum extruded pipe as a blank material, and is cut to form a hollow step frame, and the step frame is processed through a common drilling operation to penetrate the joint hole, and then on both sides of the joint hole The tube holder is respectively welded to have sufficient contact area to provide a mandrel pivoting therein, thereby manufacturing the step frame and the tube seat, so that the defects of the metal die-casting or plastic injection molding pedal of the present invention are eliminated. [Embodiment] 201041778 In order to enable the reviewing committee to further understand the structure, features and other objects of the present invention, the drawings of the preferred embodiments are described in detail as follows: Please refer to Figures 1 to 4, the pedal of the present invention. The following processes are completed: A. Cutting process: a long strip of metal substrate is punched out by a punching machine, and the sides of the substrate have jagged claws on both sides, and the central portion is continuous. There is a coupling hole (11), and another half of the substrate is punched with another coupling hole (110); 5 B. Bending molding: the metal substrate is bent and shaped to be butt-joined to form a four The hollow step frame (10) is closed, and the two coupling holes (11) (110) are arranged in a relatively concentric manner; C. Welding processing: the step frame (10) is in the opposite two coupling holes (10 (110) The outer position is concentrically welded with a tube seat (12); * D. Assembly: the inner holes (120) of the two tube seats (12) are each provided with a 'plastic bushing (31), and combined in two An outer q-tube (32) is bridged between the holes (11) and (110), and two ends of the outer tube (32) are bounded by two bushings (31), and the outer tube (32) and the bushing (31) are centered. A shaft hole (320) (310) is disposed, and a bearing (33) and a leakage preventing washer (34) are arranged in the shaft hole (310) of the bushing (31), so that the two bearings (33) can provide a spindle (20) penetrating, and the mandrel (20) can be locked to the crank, and the other end is provided with an externally threaded section (21). In addition, the threaded section (21) provides a nut (35) locking knot. And the bushing (31) at the other end of the mandrel (20) is one The cap (36) is closed, and the bushing (31), the outer tube (32), the bearing (33), and the mandrel (20) are fixed by the locking stress of the nut (35) to 5 201041778 enables the step frame (10) to freely rotate around the mandrel (20), providing bicycle pedaling. From the above structural description, the present invention has at least the following advantages: (1) The material of the present invention can be made of any metal, and the material thereof is not limited. (2) The cost of the apparatus of the present invention is much lower than that of the die-casting molding, so that it is used in a small amount of diversified production and does not require deep hole processing, so that it is economical. (3) The present invention is formed by cold forming, so that the airtightness of the finished product is excellent, which minimizes the corrosion of the mandrel. (4) Since the step frame (1 inch) of the present invention is made of metal, its overall structural strength is much better than that of plastic injection molding. In addition, the foot pedal of the present invention can also be completed as follows: A. Cutting processing: a metal rolling pipe or an aluminum extruded pipe is selected as a blank material to be cut into a hollow step frame (1〇); B·Drilling processing··This step frame (1〇) is joined by the general drilling operation (11) (110); C.
