Description

Technical Field

[0001] The present invention belongs to the technical field of stamping devices, and particularly relates to a device for forming different types of handles and a method for using the same. Background Art

[0002] Handle parts need to be assembled on electronic chassis equipment to facilitate its handling. In electronic chassis equipment, each functional module is often installed in a pluggable form. To facilitate the disassembly and assembly of each functional module, handle parts are also installed on it. Considering factors such as ergonomics and forming difficulty, the handle profile is generally made into an oval or circular cross-sectional shape. Due to the different sizes of the electronic chassis equipment and each inserted functional module, the sizes of the handle parts are not uniform.

[0003] Currently, the handle can be formed by a fitter's manual bending method. However, although the handle structure is simple, the manual manufacturing process is numerous, and it is difficult to meet the requirements of flatness, symmetry, and perpendicularity after bending. At this time, most of them still need to be shaped and milled to make both sides symmetrical, which makes it difficult to ensure the consistent forming quality of the handle by manual bending. The handle can also be formed by a bending machine. However, due to the limitations of the bending machine itself, it can only process handles with larger width dimensions. When the handle width is small and the depth-width ratio is large, the bending machine is difficult to form. The handles formed by the bending machine also have inconsistent flatness on both sides and distortion, and still need to be shaped.

[0004] As a low-value small part, when the handle is mass-produced, it is also necessary to consider controlling the production cost. Therefore, it is considered to use a set of adjustable tooling molds to make handles with different cross-sectional shapes and width dimensions, which can not only improve the production quality and production efficiency but also save the production cost. Summary of the Invention

[0005] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide a device for forming different types of handles and a method for using the same, which can realize the forming of different types of handles by adapting stamping parts and adjusting the position of the forming device.

A retractable unloading device is installed on the support device. The unloading device is located below the punch upper die. Forming devices are arranged on both sides of the unloading device. An adjusting device is installed on the support device. Two output ends of the adjusting device are respectively connected to the two forming devices. The handle blank to be stamped is placed between the punch upper die, the unloading device, and the two forming devices.

[0007] The handle forming device of the present invention can realize one-time forming of the handle, avoiding the cumbersome process of the original manual bending forming and solving the problem of inconsistent manual forming quality; at the same time, it replaces the bending forming by the bending machine, solves the problem that the bending machine is difficult to bend the handle with a small width and a large depth-to-width ratio and needs to be calibrated after bending, thereby improving the forming efficiency and forming quality of the handle.

[0008] The present invention designs a matching punch upper die, a forming device and a discharge device, and adopts a method of continuously adjusting the distance of the forming device, so that a set of tooling can form handles of different types and sizes, thereby reducing the cost and difficulty of mass production of handles.

[0009] As a preferred solution of the present invention, the punch upper die comprises a punch handle mounted on a punching machine, the punch handle is connected to a punch through a cylindrical pin, a groove matching the shape of the handle is provided on the punch, and the handle is formed mainly by the force applied by the punch.
