Description

TECHNICAL FIELD

[0001] The utility model relates to aluminum profile stretching straightening technical field, specifically a kind of stretching straightening machine for aluminum profile production. BACKGROUND

[0002] Stretching straightening machine is fixed the both ends of aluminum profile by clamp, and aluminum profile is stretched using mechanical force. When stretching force exceeds the yield strength of material, plastic deformation occurs in aluminum profile, and the internal stress originally existing in aluminum profile is released and redistributed, so that the purpose of stretching straightening is achieved. In the production process of aluminum profile, due to the influence of factors such as raw material quality and processing technology, bending deformation and other problems often occur in aluminum profile. Traditional straightening machine has certain limitations in straightening effect, efficiency and adaptation to aluminum profiles of different specifications. For example, some straightening machines cannot accurately control the stretching degree, which leads to overstretching or insufficient stretching of aluminum profile, affecting product quality. Moreover, the general applicability of the straightening machine is poor for aluminum profiles of different cross-sectional shapes and sizes.

[0003] Now the traditional straightening machine cannot accurately control the tension. Therefore, when stretching, the aluminum profile may break, and the stretching straightening machine may cause the stretched aluminum profile to bend when one of the straightening machines moves a long distance, because the distance between the two straightening machines is too large and there is no support for the aluminum profile. Therefore, it is difficult to effectively ensure the quality of stretching and straightening. With the advancement of technology, a support beam that can rotate is provided at the edge of the frame in the traditional equipment. When the support beam rotates, the radius of rotation is large, and people passing by may be injured when the support beam rotates.

[0004] After searching, Chinese patent publication No. CN201620775293.5 discloses a fast-forward type aluminum profile straightening machine. The machine includes a support, a movable front jaw and a rear jaw arranged opposite to each other on the support for clamping aluminum profile, an upper feeding device arranged at the front jaw for feeding aluminum profile, an upper pressing plate pressing cylinder mounted on the front jaw for driving the front jaw to clamp aluminum profile, a fast-forward type main oil cylinder for driving the movable front jaw to move linearly and reciprocally, and a movable front jaw rotating oil motor for providing hydraulic oil to the fast-forward type main oil cylinder.

[0005] When the equipment in the above patent works, the movement of the rear jaw and the movable front jaw realizes the processing of the profile. When the rear jaw moves away from the movable front jaw, there is no support structure between the rear jaw and the movable front jaw for the profile. Therefore, when the stretched profile is long, the middle position of the profile may sag, the stretched profile is bent, and the working quality of the rear jaw and the movable front jaw cannot be effectively guaranteed.
