Embodiment Construction
[0029] 1. Print the mark, lay flat steel strips with a cross-sectional size of 3 to 6 times the size of the spokes on the work site, and then use a steel ruler of double the fixed length to mark the line, and finally print the mark; theory The longer the double-size material, the better, so that the head and tail of the material can be distributed more, and the utilization rate of the material can be improved. However, due to transportation reasons, it can only be 3 to 6 times.
[0030] 2. Coil, put the stamped flat steel into the rounding machine for rolling, and get the spiral coiled material. The elongation difference between the first piece and the last piece of the same coiled material is 2~ 5. Therefore, it is necessary to mark the line first and then roll it round to ensure that the deformation of each piece is consistent, and ultimately to ensure the stability of the product; figure 2 shown.
[0031] 3. Cut the material, cut the coiled material according to the impri...

The invention provides wheel spoke cold press molding machining technology, relates to mechanical part punching technology and in particular to the spoke cold press molding machining technology for various wheels. The wheel spoke cold press molding machining technology comprises the following steps of 1 imprinting, 2 coiling, 3 cutting materials, 4 forming a groove, 5 point-welding, 6 welding, 7 polishing, 8 molding and 9 lathing. The wheel spoke cold press molding machining technology comprises the key molding processes: 1, roundness is guaranteed through expansion; and 2, flatness is guaranteed through flat pressing. According to an abstract picture, an expanding flat mold is composed of three main parts, namely, a tension cone, a tension block and a pressing flat mold. Accuracy size of a spoke can be adjusted through addition and reduction of spacers between the tension cone and a tension cone fixed seat and addition and reduction of spacers between the pressing flat mold and a pressing flat mold seat. The wheel spoke cold press molding machining technology has the advantages that the problems that existing wheel spoke technology is large in energy waste and low in production efficiency and flow line production is not prone to be formed are solved and the flatness and surface roughness of the spoke are improved.
Description
technical field [0001] The invention relates to a stamping process for mechanical parts, in particular to a cold-press forming process for spokes on various wheels. Background technique [0002] At present, in order to save materials, strips are generally used to make spokes, and the squares are first made into strips; 1. Either made into a cylinder, then heated and flared, and then formed and flattened, such as patent number CN200510079704.3 2. Either heating to form a spiral blank, and finally heating and forming to flatten, such as CN200910118386.5 Wheel spoke plate manufacturing process of wheel construction machinery and its special Vertical coiling machine; although it saves a certain amount of material, it consumes a lot of energy, and the flatness is poor, indicating that the roughness is poor, and the heating time is long, the production efficiency is low, and it is not easy to form an assembly line production. Contents of the invention [0003] The technical pro...
