Description

Technical Field

[0001] This utility model relates to the field of tooling technology, specifically to a bending tool with graduations. Background Technology

[0002] Chinese utility model patent application CN20242093297.4 discloses a bending fixture, which includes a base, a clamping and positioning mechanism, and a pressing component. When a bending operation is required on a component, the present application first drives a moving component to approach a fixed base, clamping the first part of the component to be bent between the fixed base and the moving component. A pusher block then presses the second part to bend both the first and second parts to a preset angle, thus achieving the bending of the first and second parts of the component. This application replaces manual bending of the component by using a clamping and positioning mechanism and a pressing component, reducing the labor intensity of workers. Furthermore, the bending fixture is easy to operate and ensures consistency in the bending of each component. Although the bending fixture disclosed in this patent can effectively bend objects including metal sheets, the lack of graduations on the fixture makes it difficult to clearly and quickly determine whether the bent object has reached the required bending dimensions, thus reducing the progress of the bending process to some extent. Summary of the Invention

The first clamping plate is connected to the active clamping component on one side and to the passive clamping component on the other side. By driving the active clamping component to work, the active clamping component causes the first clamping plate to move towards or away from the second clamping plate. When the first clamping plate moves towards the second clamping plate, the workpiece to be bent, placed between the first clamping plate and the second clamping plate, is bent. The first graduated plate and the second graduated plate are respectively disposed on both sides of the workpiece to be bent, and the first graduated plate and the second graduated plate remain stationary during the bending process.

[0009] Preferably, the passive clamping assembly includes a sliding guide post, a linear bearing, and a second connecting plate. The linear bearing is sleeved on the sliding guide post and is slidable on the sliding guide post. The second connecting plate is connected to the linear bearing. The first clamping plate and the second connecting plate are fixedly connected together, so that when the first clamping plate moves, it drives the second connecting plate to move, and the second connecting plate drives the linear bearing to slide on the sliding guide post.

[0012] The beneficial effects of this application are: the graduated bending fixture provided by this application has a simple structure. The active clamping component of the bending mechanism drives the first clamping plate to move toward or away from the second clamping plate. When the first clamping plate moves toward the second clamping plate, it bends the metal sheet placed between the first clamping plate and the second clamping plate. Since a first scale plate and a second scale plate are also provided, the degree of bending of the metal sheet can be observed intuitively and conveniently after the metal sheet is bent, so that the degree of bending can be quickly corrected, thereby improving the bending efficiency to a certain extent.
