Description
Technical Field
[0001] The invention relates to the technical field of spring forming, and in particular to a high-strength plane scroll spring forming device and process. Background Art
[0002] Planar spiral spring, also known as spring spring, is a spring with one end fixed and the other end acting on torque. Under the action of torque, the spring material produces bending elastic deformation, causing the spring to twist in the plane, and the size of the deformation angle is proportional to the torque.
[0003] Hand-held winding, lathe winding or special tool winding can be used. When winding, attention should be paid to controlling the number of coils, diameter and spacing of the spring to ensure that the performance of the spring meets the requirements. In actual use, the factory will need a flat scroll spring with no spacing, and the flat scroll spring produced by traditional machinery cannot achieve zero spacing, resulting in the flat scroll spring produced not meeting the use requirements.

[0007] In actual application, when the third bevel gear rotates forward, the first bevel gear rotates accordingly. However, since a one-way bearing is arranged between the rotating shaft and the first bevel gear, the first bevel gear will not drive the rotating shaft to rotate. When the third bevel gear is reversed, the first bevel gear drives the rotating shaft to rotate, and the rotating shaft drives the limit group to move, and the limit group slides inside the slide groove, thereby driving the telescopic cylinder to reciprocate and extend, and then push the workpiece out, thereby completing the function of automatic collection.
[0008] Further, the bending mechanism includes a first spur gear, the central axis of the first spur gear is connected to the output shaft of the motor, a rotating disk is fixedly provided at one end of the first spur gear, a fixed column is fixedly provided at one end of the rotating disk, and a bending groove is provided in the middle of the fixed column;
[0009] In actual applications, the workpiece to be processed is transported to the inside of the bending groove through the guide wheel, and then the motor output shaft drives the first spur gear to rotate, and the first spur gear drives the rotating disk and the fixed column to rotate, so that the fixed column bends the workpiece, and then after continuous rotation, the flat scroll spring is formed, thus eliminating the need for too many other operations and saving time.

[0011] The pressing column comprises a fixing rod rotatably connected to the sliding seat, a tension spring is fixedly arranged on the outer surface of the fixing rod, the tension spring is evenly distributed on the outer wall of the fixing rod, and the other end of the tension spring is commonly connected to the pressing cylinder;
[0012] In actual application, the first spur gear drives the second spur gear to rotate, the second spur gear drives the second bevel gear to rotate, the second bevel gear drives the rotating rod to rotate, the rotating rod drives the threaded seat to move, the threaded seat drives the sliding seat to move, and the sliding seat drives the pressing column to move, so that the planar scroll spring fits tightly.
[0013] Further, the high-strength planar scroll spring forming process comprises the following steps:
[0014] Material preparation: Select suitable materials, such as rectangular steel strips or round steel wires, and perform annealing treatment to reduce the hardness of the material and improve its plasticity.
[0015] Winding spring: The annealed material is formed into a spiral shape through this device.
[0016] Heat treatment: The wound spring is heat treated, including quenching and tempering. Quenching can improve the hardness and strength of the spring, while tempering can reduce the brittleness of the spring and improve its toughness. The temperature and time of heat treatment should be adjusted according to the type of material and the requirements of the spring.
[0017] Surface treatment: The spring after heat treatment is subjected to surface treatment, such as oxidation treatment or other anti-corrosion treatment, to improve the corrosion resistance and aesthetics of the spring.
[0018] Inspection and packaging: The springs are inspected, including size, shape, hardness, elasticity, etc., to ensure that the quality of the springs meets the requirements. After passing the inspection, the springs are packaged for storage and transportation.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. In this device, when the third bevel gear rotates forward, the first bevel gear rotates accordingly. However, since a one-way bearing is provided between the rotating shaft and the first bevel gear, the first bevel gear will not drive the rotating shaft to rotate. When the third bevel gear rotates reversely, the first bevel gear drives the rotating shaft to rotate, and the rotating shaft drives the limit group to move, and the limit group slides inside the slide groove, thereby driving the telescopic cylinder to reciprocate and extend, and then push the workpiece out, thereby completing the function of automatic collection.
[0021] 2.
