Chinese patent application 200910222533.3 discloses a fully automatic valve heating disc rod straightening machine. The straightening of the valve rod is realized by two rollers against rollers, which is similar to the way thread rolling machines process threads. The alignment is controlled by adjusting the distance between the two rollers. Straight force, the straightening effect is poor; the disc correction is realized by the tapered ball, because the straightening reaction force is carried by the tapered ball, its strength is insufficient, and it is easy to get stuck, and most of the applications need to be manually corrected again

Embodiment Construction
[0025] Such as Figure 1 to Figure 13 As shown, an embodiment of the present invention includes a machine base 1, on which a first shaft 31, a second shaft 32 and a balance correction mechanism 2 are arranged, and the first shaft 31 and the second shaft 32 are horizontal Shaft, the first shaft 31 is located on the upper side of the second shaft 32, the axis of the first shaft 31 and the plane where the axis of the second shaft 32 are located are perpendicular to the horizontal plane, and a pair of upper rollers 3 are fixed on the first shaft 31. A pair of lower rollers 4 are fixed on the second shaft 32 (for the convenience of clear positional relationship, image 3Among them, the distance between the upper roller 3 and the lower roller 4 has been enlarged), the power drives the first shaft 31 and the second shaft 32 to rotate in the same direction and at the same speed through the worm gear mechanism 5; the balance wheel correction mechanism 2 includes a Fork arm 6, a third ...

The invention discloses a straightening machine for valve plates and rods. The straightening machine comprises a base. A first shaft, a second shaft and a balance wheel rectifying mechanism are arranged on the base, a pair of upper rollers is fixed onto the first shaft, a pair of lower rollers is fixed onto the second shaft, the balance wheel rectifying mechanism comprises swing arms, a swing rod, a fourth shaft, a rectifying roller, a rectifying bevel wheel, a limiting pressing wheel and a constant-force cylinder, and power drives the first shaft, the second shaft and the fourth shaft via a worm and gear mechanism to rotate in identical directions at identical speeds; the swing arms capable of swinging left and right can drive the rectifying roller and the rectifying bevel wheel to swing left and right, so that rod ends of valve workpieces can be straightened, and plate ends of the valve workpieces can be rectified. The straightening machine has the advantages that a lever mechanism, a connecting rod mechanism and an eccentric wheel mechanism are smartly combined with one another, accordingly series plate and rod straightening actions can be implemented on the valve workpieces, and the straightening machine is exquisite in structural design, high in efficacy and reliable in performance.
Description
technical field [0001] The invention relates to a processing device for an engine valve, in particular to a straightening processing device for a valve blank after heat treatment. Background technique [0002] The valve blank is usually made of electric upsetting forging or precision casting and heat treatment. During the production process, there will be bending deformation. If it is not straightened, it will directly affect the processing of subsequent parts, and even a considerable amount of waste products will appear. . The traditional process mostly adopts manual alignment, the amount of alignment is difficult to control accurately, the alignment accuracy and efficiency are low, the labor intensity is high, and it is difficult to meet the requirements of industrial mass production. In the world, only a few developed countries such as MAE in Germany, GALDABINI in Italy, and Towa Seiki in Japan produce valve processing equipment, but they are mainly used for supporting e...
