Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a bending machine with an adjustment function. Background Art

[0002] Auto parts are the various units that constitute the overall processing of auto parts, as well as the products that serve the processing of auto parts. There are many kinds of auto parts. With the improvement of people's living standards, people's consumption of cars is increasing, and the market for auto parts is becoming larger and larger. In the processing of auto parts, steel plates need to be bent, so a bending machine is needed for bending processing.

[0003] For example, a steel plate bending machine for automobile parts processing disclosed in publication number CN218873361U can drive a screw rod to rotate by setting a driving motor, and the screw rod drives the bending mold thereon to move, so that the position of the bending mold with different opening angles can be adjusted according to actual needs. Therefore, when there is a need for different bending angles, it can meet the needs well.

[0004] However, the above-mentioned adjustment structure is less practical when used. When the above-mentioned bending machine processes different bending angles, it drives multiple groups of bending molds thereon to move for selection through a screw rod. This is not only less practical, but can only install individual molds, and it is impossible to finely adjust the bending angle, thus affecting the use effect. In view of this, we propose a bending machine with an adjustment function. Utility Model Content

[0012] Compared with the prior art, the utility model provides a bending machine with an adjustment function, which has the following beneficial effects:

[0013] 1. The bending machine with adjustment function is convenient for adjusting the bending angles of the two sets of bending plates by setting an adjustment structure. The user can drive the sleeve to move up and down by rotating the screw, and drive the two sets of L-shaped rods to move left and right inside the slide groove by the movement of the sleeve. The upper ends of the two sets of bending plates are moved relatively and adjusted by the movement of the L-shaped rod, thereby improving the practicality of the device without installing many sets of different bending frames.

[0014] 2. The bending machine with adjustment function is provided with a protective structure to protect the bent automobile parts and two sets of bending plates. As the automobile parts are bent by the bending structure, the two sides of the automobile parts will gradually contact the surface of the bending plate. At this time, the side wall of the automobile part will contact the protective plate and drive it to move. The movement of the protective plate causes the contact plate on the side wall of the moving rod to move. The contact plate moves and contacts with the contact switch so that the bending structure no longer moves downward, thereby facilitating the use of the device. BRIEF DESCRIPTION OF THE DRAWINGS
