[0002] At present, the pedal tube of an electric bicycle is usually a U-shaped tube formed by two side tubes and a top tube. During the processing of the pedal tube of an electric bicycle, the two side tubes need to be pressed by an electric bicycle pedal tube pressing mold. The existing electric bicycle pedal tube pressing mold mainly consists of an upper mold plate 109, a punch 110, a concave mold 107, a punching upper mold 108, a punching lower mold 106, a lower mold plate 105, a guard plate 104, a lower mold block 103, an upper mold block 102, a positioning component 101, etc. Figure 1 As shown; Traditional lower die structure: a countersunk hole is drilled at the bottom of the lower die plate, which is fixed to the die with bolts; the front and rear positioning components are fixed to the lower die plate with bolts; a countersunk hole is drilled at the bottom of the lower die plate, which is fixed to the punching lower die with bolts; the lower die block (made of hard nylon) has a round hole, which is fixed to the die with bolts; Traditional upper die structure: a countersunk hole is drilled at the top of the upper die plate, which is fixed to the punch with bolts; a countersunk hole is drilled at the top of the upper die plate, which is fixed to the punching upper die with bolts, the upper die block (made of hard nylon) has a round hole, which is fixed to the punch with bolts; there are holes on the left and right sides of the die, and the die is fixed to the protective plate with bolts. The function of the protective plate is to prevent employees from reaching into the mold cavity during operation to avoid safety accidents.

[0004] The existing electric bicycle pedal tube profiling mold structure is a single-tube processing form, and the left and right side tubes of the pedal tube need to be profiled twice, which has high processing costs and low processing efficiency. In addition, due to mold limitations, the vehicle frame can only be designed as a split pedal tube form; the front and rear positioning components are movable structures, which need to be adjusted and fixed after the tube is bent, and the profiling position can be adjusted flexibly, which poses a risk of poor quality; the upper and lower molds need to be adjusted when the mold is changed, and the mold changing time is long; the profiling depth of the pedal tube is the height of the punch rib, and the height cannot be adjusted. When the depth design is changed, the punch needs to be remade or modified, and the processing is relatively complicated. Utility Model Content
