Technical Field
[0001] The utility model relates to the technical field of metal bar straightening, in particular to a straightening machine system and a noise reduction material guiding component thereof. Background Art
[0002] In the automobile manufacturing industry, in order to improve the utilization rate of raw materials, the surface roughness and the yield strength, long metal bars (for example, with a length of 6-7 meters) need to be drawn. The stress generated after drawing causes the bars to bend. Before blanking, in order to eliminate the bending defects, the bars need to be straightened by a straightening machine system. The straightening machine system includes a straightening machine and a material guiding component arranged on the front side of the straightening machine. The axes of the upper and lower rollers of the straightening machine are arranged at a certain angle. Before the bar is straightened, it is first placed in the material guiding component. When straightening, the operator transports the head of the bar between the upper and lower rollers of the straightening machine, and the bar will rotate into the straightening machine. Since the bar is bent and rotates in the material guiding component, the bar continuously knocks on the material guiding component, generating noise pollution and even seriously affecting the physical health of the operator.

A second notch is provided on the upper side of the outer material guiding pipe 3, and the second notch extends from one axial end of the outer material guiding pipe 3 to the other axial end. Preferably, the central angles of the first notch and the second notch are each approximately 90°. One side where the first notch and the second notch are adjacent is connected by a first connecting plate 31, and the other side where the first notch and the second notch are adjacent is connected by a second connecting plate 32 to form an inlet of the material guiding pipe assembly. The bent bar after drawing falls into the inner material guiding pipe 2 from the inlet. Preferably, the first connecting plate 31 and the second connecting plate 32 are respectively fixed in corresponding positions by welding.
[0030] The two axial ends of the inner material guiding pipe 2 are flush with the two axial ends of the outer material guiding pipe 3 respectively. The first sealing plate 4 is mounted on the two axial ends where the inner material guiding pipe 2 and the outer material guiding pipe 3 are adjacent, and the second sealing plate 5 is mounted on the other two axial ends where the inner material guiding pipe 2 and the outer material guiding pipe 3 are adjacent.
