Technical Field

[0001] The utility model relates to an auxiliary device for plate forming equipment, in particular to an improvement on the plate positioning finger structure of a bending machine. Background Art

[0002] Press brakes are commonly used in sheet metal processing. With the increasing demand for production efficiency, efficient and quick bending of workpieces has become a key concern for companies. In "CN 213409953 U, Press Brake Finger," filed on October 27, 2020, the applicant proposed achieving two-stage bending positioning of sheet metal using stoppers provided on extension blocks and sliders. However, in actual applications, multiple stop fingers of different lengths are required. This necessitates replacing the stop fingers, which is cumbersome, time-consuming, and labor-intensive.

[0003] Therefore, how to design a bending machine finger with multi-gear adjustment to adapt to different needs has become a technical problem that needs to be solved urgently. Summary of the Invention

[0004] In response to the above technical problems, the utility model provides a multi-level adjustable finger stop device for a bending machine which has a simple structure, is easy to operate, does not require frequent replacement, and can be adjusted in multiple levels in the transverse direction.

[0005] The technical solution of the utility model is as follows: comprising a base (1) and a slider (2), and also comprising a finger-blocking arm (3) and a telescopic arm (4);

Both sides of the telescopic arm (4) are provided with a limit block placement hole (42). The telescopic adjustment of the telescopic arm (4) is achieved through a limit mechanism in the positioning hole (32).

[0010] Furthermore, no less than two pairs of positioning holes (32) are provided in the T-shaped finger-blocking arm sliding groove (31).

[0011] Furthermore, the limiting mechanism comprises a bolt, which is adjustably fixedly connected to the positioning hole (32) via a thread, and the tail end of the bolt extends into the positioning block placement hole.

[0013] A spring (71) is provided in the positioning hole (32), and an adjusting button (7) is provided on the spring (71);

[0014] The limit block (43) is installed in the limit block placement hole (42). The limit block (43) is a double-layer sleeve structure. A built-in spring is provided in the limit block (43). When the limit block (43) is pressed, the vertex of the inner tube is parallel to the top surface of the limit block placement hole (42).

[0015] Compared with the existing technology, the bending machine stop finger of the utility model can complete multi-level adjustment of the stop finger in the lateral direction through the stop finger arm, telescopic arm and positioning mechanism. When the bending machine stop finger of different lengths is required, there is no need to remove the original bending machine stop finger. The adjustment can be completed by pressing the adjustment button and pulling the telescopic arm. The operation is simple, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS
