Description

Technical Field

[0001] The utility model relates to the technical field of hardware bending, in particular to a hardware product bending device. Background Art

[0002] Hardware products are auxiliary and accessory products used in daily life and industrial production. In the early days, they were mostly made of metal materials such as gold, silver, copper, iron, and tin, hence the name. In addition to various metal materials, they are now widely made of non-metallic materials such as plastics and glass fibers.

[0003] Most existing hardware products are bent by bending devices during the production process, but the bending angles of most bending devices are fixed. If they are bent to different angles, they need to be replaced with new devices or disassembled and replaced with bending blocks of corresponding angles. This process is not only time-consuming and labor-intensive, affecting work efficiency, but also increases production costs. Utility Model Content

[0004] The utility model aims to provide a hardware bending device to solve the problem that the bending angles of existing hardware bending devices are mostly fixed values. If bending to different angles is required, a new device needs to be replaced or the bending blocks need to be disassembled and replaced with corresponding angles. This process is not only time-consuming and labor-intensive, affecting work efficiency, but also increasing production costs.

[0005] To achieve the above-mentioned purpose, a hardware product bending device is provided, including a workbench, a rotating cylinder is rotatably connected to the middle of the workbench, the rotating cylinder is located on the outer side of the bottom end of the workbench and is fixedly connected to a driven gear, the bottom end of the workbench is rotatably connected to a transmission shaft, a pair of first brackets symmetrically arranged with the transmission shaft as the axis are fixedly connected to the bottom end of the workbench, a first servo motor coaxial with the transmission shaft is fixedly connected to the bottom end of the first bracket, a transmission gear meshing with the driven gear is fixedly connected to the outer side of the transmission shaft, a bending block is fixedly connected to the top end of the rotating cylinder, and a limit block with an adjustable bending angle is arranged in the middle of the top end of the rotating cylinder.

[0006] As a further improvement of the technical solution, a rotating column is rotatably connected inside the rotating cylinder, a pair of second brackets symmetrically arranged with the rotating column as the axis are fixedly connected to the bottom end of the workbench, a second servo motor coaxial with the rotating column is fixedly connected to the bottom end of the second bracket, and a limit block is fixedly connected to the middle part of the top end of the rotating shaft.

[0007] As a further improvement of the technical solution, a pair of fixed plates are fixedly connected to the top of the workbench, and fixed cylinders are fixedly connected to opposite sides of the pair of fixed plates. An extrusion block is provided on one side of the fixed cylinder close to the center of the rotating column.

[0008] As a further improvement of the technical solution, an elastic component applicable to hardware of different thicknesses is provided between the fixing cylinder and the extrusion block.

[0009] As a further improvement of the technical solution, a return spring is fixedly connected between the sliding column and the fixed cylinder, and the extrusion block is fixedly connected to one side of the sliding column.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The hardware bending device drives the rotating cylinder to rotate by the first servo motor, so that the bending block can bend the hardware supported by the limit block, and drives the rotating column to rotate by the second servo motor, so that the limit block can be adjusted to different angles along with the rotating column, so as to realize bending of the hardware at different angles. The setting of the extrusion block can clamp and fix the workpiece when it is bent, reducing the risk of manual hand-held injury. The elastic component between the fixed cylinder and the extrusion block can realize bending of tubular, plate-shaped or other long hardware. BRIEF DESCRIPTION OF THE DRAWINGS
