Inconvenient to operate, easy to injure the operator.

2. Although the horizontal automatic steel bar bending machine in the prior art can bend in both directions, the minimum size of the bending is limited due to its excessive size. The minimum bending length of the horizontal automatic steel bar bending machine in the prior art is 1.5m; the positive and negative bending angle displacement is small, only ±90°; the operation process of the horizontal automatic steel bar bending machine in the prior art is complicated.

3. The prior art horizontal steel bar automatic bending machine includes a fixed bending machine and a mobile bending machine, the bending process takes a long time and the production efficiency is low.

Another object of the present invention is to provide a two-way mobile vertical steel bar automatic bending machine with a vertical working surface, convenient and safe loading and unloading operations, and easy measurement of the workpiece size.

The technical solution to solve the above technical problems is: a two-way mobile vertical automatic bending machine for steel bars, the two-way mobile vertical automatic steel bar bending machine includes: a track, an automatic steel bar bending machine moving on the track, and a steel bar pressing device. The steel bar pressing device is arranged on one side of the track; the steel bar automatic bending machine includes the first steel bar automatic bending machine and the second steel bar automatic bending machine corresponding to the same position of the structure; the first steel bar automatic bending machine and the second steel bar automatic bending machine The bottom of the bending machine is respectively provided with a two-way traction mechanism with the same structure to drive it to move on the track and a locking mechanism to lock it on the track.

The beneficial effects of the present invention are: the present invention overcomes the defects of the prior art, the bending mode is changed from horizontal to vertical, the operation is easier, the safety of the operator is guaranteed to the greatest extent, and the humanized operation mode is realized. The minimum bending length of the present invention is only 460mm, which increases the displacement range of positive and negative bending angles. The bending process is controlled by a numerical control system, which has a high degree of automation and is easy to operate. The invention adopts two bending machines to move quickly left and right to bend the steel bar at the same time, which obviously shortens the bending and forming time of the steel bar and improves the production efficiency. The invention also has the advantages of simple structure, convenient maintenance, stable operation, energy saving and low processing cost.
