Improved Stretch Bending Machine

Abstract

The invention provides an improved stretch bending machine, which includes a machine base, a rotating arm and a stretching mechanism. Both sides of the machine base are rotatably provided with rotating arms, each rotating arm is provided with a stretching mechanism, and the stretching mechanism It includes a support base, a stretching drive cylinder, a collet connection seat, a collet, a lifting seat, a top cover, a lifting screw and a lifting nut. The support base is set on the rotating arm, and the stretching drive cylinder is installed on On the support seat, the piston rod end of the stretching drive cylinder is provided with a collet connection seat, and a collet for clamping the end of the profile is detachably installed on the collet connection seat. The top cover is fixed on the top of the support seat, and the top cover A through hole is opened on the top cover, and the lifting screw rod passes through the through hole of the top cover and is fixedly connected with the lifting seat. A section of the lifting screw rod above the top cover is screwed with a lifting nut. The improved stretch bending machine can realize stretch bending in different directions for profiles of different specifications.

Description

technical field [0001] The invention relates to the technical field of stretch bending of metal profiles, in particular to an improved stretch bending machine. Background technique [0002] Stretch bending machine is the main equipment used for stretch bending steel, aluminum and other profiles. Chinese invention CN 208825269U discloses a stretch bending machine, but the piston cylinder and snap joint of the stretch bending machine are fixed in the vertical direction, so it can only meet the stretch bending of profiles with specific specifications. In addition, the Chinese invention CN 205629010 U discloses an integrated stretch bending machine, the clamping device and filling device of which are fixed in the vertical direction, which also has the above-mentioned problems. It can be concluded that the function of the existing stretch bending machine is relatively single, that is, it is specially designed according to a certain steel or aluminum profile that needs to be stre...

AI Technical Summary

Problems solved by technology

It can be concluded that the function of the existing stretch bending machine is relatively single, that is, it is specially designed according to a certain steel or aluminum profile that needs to be stretched and bent in batches, and the stretch bending of steel, aluminum profiles and other profiles is also limited to Stretch bending in a certain direction, or limited to a certain specification and model, has a small scope of application, but in actual use, there are many types of profiles that need to be used. In the actual operation process, the existing stretch bending machine can no longer At the same time, it is necessary to improve the existing stretch bending machine so that it can stretch most of the profiles.
