Abstract
Description
Technical Field
[0001] This utility model relates to a simple bending tool for plastic wire, belonging to the technical field of bending equipment. Background Technology
[0002] Currently, bending tools are indispensable equipment in the existing plastic wire processing field. To meet the bending requirements of different angles and shapes, complex mechanical devices are usually required. These devices are often expensive, complicated to operate, have high maintenance costs, and are not easy to carry and move. For some small-scale processing applications or temporary work environments, the limitations of these traditional bending tools are particularly obvious.
[0003] A search revealed a Chinese patent, CN212577364U, which discloses a wire harness bending fixture. In this patent, the wire harness to be bent is placed flat along the area enclosed by a limiting component, with the starting end pressed against a fifth stop to prevent slippage. The main body of the wire harness is located between the first and second stops. When the wire harness extends to the inclined section of the third stop, the worker bends it along the inclined direction of the third stop, using the physical limiting effect of the stops to ensure consistency in the bending angle and position. The wire harness is then further aligned along the direction of the fourth stop, ultimately forming a bent wire harness that conforms to a preset angle. However, the bending angle of this patent is relatively fixed, resulting in low applicability, and manual bending is required when encountering wire harnesses with a certain degree of rigidity. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a simple bending tool for plastic wires. It can achieve multi-angle bending, is easy to operate and improves the adaptability to wires of different hardness.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a simple bending tool for plastic wire, comprising:
[0006] Fixed base;
[0007] A placement platform is mounted on the fixed base, and a first baffle is installed on the placement platform;
[0008] A first bending assembly includes a fixed base, a first bending seat, an operating handle, and a first bending head. The fixed base is mounted on the fixed base, and a connecting shaft is mounted on the fixed base. The first bending seat is rotatably mounted on the fixed base via the connecting shaft. The operating handle is connected to the first bending seat. The first bending head is mounted on the first bending seat, and a first through groove is provided between the first bending head and the connecting shaft. The first bending seat is adapted to rotate to drive the first bending head to bend the shaped wire passing through the first through groove.
[0009] Furthermore, in order to effectively support the wire harness, the first baffle is higher than the plane of the placement platform;
[0010] Multiple second bending heads are provided next to the first baffle, and the top of the first baffle and the top of the second bending head are on the same plane.
[0011] Furthermore, a second passage groove is provided between the first baffle and the second bending head;
[0012] The distance between any two adjacent second bends is equal.
[0013] Furthermore, in order to provide different bending methods, a simple bending tool for plastic wire also includes a second bending assembly, which includes a bending push rod and a third bending head. The bending push rod is mounted on the placement platform, and the direction of movement of the bending push rod is consistent with the length direction of the placement platform.
[0014] The placement platform is provided with a sliding groove, and the third bending head is slidably installed in the sliding groove. The third bending head is connected to the bending push rod.
[0015] Furthermore, in order to reduce damage to the wire during bending, the top of the third bending head is provided with an inclined surface, and the third bending head faces the shaped wire in the first through groove.
[0016] Furthermore, for ease of operation, the first baffle is provided with a limiting head facing the first bending seat, and the first bending seat is provided with a limiting groove. The limiting groove corresponds to the position of the limiting head. When the first bending seat rotates around the connecting shaft to a preset angle, the limiting head is embedded in the limiting groove to limit the rotation range of the first bending seat.
[0017] Furthermore, to reduce wear, a buffer pad layer is provided on the inner wall of the limiting groove.
[0018] By adopting the above technical solution, this utility model has the following beneficial effects:
[0019] In this invention, the wire to be processed is horizontally passed through the first through groove (main bending area) or the second through groove (auxiliary bending area). The second bending head of the corresponding height is selected as the fulcrum according to the target bending angle. The initial angle is determined by the pre-positioning of the limiting head and the limiting groove.
[0020] The first bending method: Hold the operating handle to drive the first bending seat to rotate around the connecting shaft, and the first bending head advances along the arc trajectory to perform bending with the connecting shaft as the fulcrum;
[0021] The second bending method: put the wire harness into the second through groove, and wrap the wire around one or more second bending heads to achieve multi-end bending as needed;
[0022] The third bending method: the bending push rod is pushed to move linearly along the sliding groove, and the third bending head gradually applies pressure through the inclined plane to achieve controllable local plastic deformation;
[0023] This bending tool achieves multi-angle plastic deformation through a three-mode bending system. It reduces the force required by utilizing the torque amplification effect of the operating handle and linear pressing mechanism, thus achieving progressive bending and effectively controlling the deformation trajectory of the wire.
