Description

Technical Field

[0001] The utility model belongs to the technical field of spring wire production, and specifically relates to a winding machine for spring wire production. Background Art

[0002] A winding machine is required in the production of spring wire. The spring wire is made by a winding machine. The winding machine is a device that winds a linear object onto a specific workpiece and is usually used for copper wire winding.

[0003] The winding machine is mainly composed of motor, high-speed shaft, magnetic pole, sliding sleeve, winding machine, etc. When the motor drives the high-speed shaft to rotate, the winding machine will follow the rotation of the high-speed shaft and start winding after the transmission of magnetic pole and sliding sleeve. When the equipment is in use, the copper wire is wound on the columnar structure through the winding machine. Since the diameter of the existing columnar structure cannot be adjusted, when making spring wires of different sizes, the columnar structure needs to be disassembled and assembled many times, which is inefficient and time-consuming, greatly increasing the labor intensity of the operator. Utility Model Content

[0004] The utility model aims to provide a winding machine for spring wire production, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a winding machine for spring wire production, comprising: a rotatable turntable, a plurality of winding arc rods are distributed in a ring array along the rotation axis on one side of the turntable, two screw sleeves are arranged on the rotation axis on one side of the turntable, and the inner side of both ends of each of the winding arc rods is provided with a connecting piece connected to the screw sleeve on the same side, and a driving piece for axial movement drive is provided between the two screw sleeves, so that the two screw sleeves are moved closer to or away from each other based on the movement, and the plurality of winding arc rods are synchronously expanded outward or closed inward.

[0006] Preferably, the driving member includes a rotating rod, and a rotating groove for accommodating the rotation of the end of the rotating rod is opened at the rotating axis of the turntable. Two first thread grooves and a second thread groove with opposite threads are sequentially provided on the rotating rod, and the two screw sleeves are respectively screwed on the first thread groove and the second thread groove.

[0007] Preferably, the connecting member comprises a first rotating seat, a connecting rod and a second rotating seat which are rotatably connected in sequence, the first rotating seat is welded to the inner side of the end of the winding arc rod, and the second rotating seat is welded to the threaded sleeve.

[0008] Preferably, a slot is provided on the outer wall of each of the winding arc rods in the axial direction, and one end of the slot extends through and extends to a side of the winding arc rod away from the rotating disk.

[0009] Preferably, the turntable is provided with movable grooves outwardly in all directions, and each end of the winding arc rod away from the slot is provided with a sliding block extending to the movable groove.

[0010] Preferably, a support frame for rotational support is provided below the turntable, and a rotating motor for driving the turntable to rotate is provided on the support frame.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The utility model adds a plurality of winding arc rods, two screw sleeves, a plurality of connecting parts and a driving part, so that the plurality of winding arc rods can be synchronously expanded outward or closed inward under the above-mentioned components, so as to facilitate the adjustment of the size of the spring wire, reduce the labor intensity of the operator, and improve the applicability of the equipment.

[0013] (2) The utility model adds a rotating rod, a first thread groove and a second thread groove. Since the threads of the first thread groove and the second thread groove are opposite, when the rotating rod is rotated, it is easy to drive the two screw sleeves to move closer to or away from each other.

[0022] As mentioned above, when using the turntable 3, multiple winding arc rods 5, two screw sleeves 11, multiple connecting parts and driving parts provided by the utility model, the distance between the two screw sleeves 11 is adjusted by the driving part, so that the two ends of the multiple winding arc rods 5 are driven to be pushed outward or retracted inward synchronously through the multiple connecting parts, and then the overall diameter of the multiple winding arc rods 5 is adjusted, so that the equipment is suitable for the production of spring wires of different sizes. At this time, one end of the spring wire is clamped on the outside of one of the winding arc rods 5, and the turntable 3 is driven to rotate, thereby driving the spring wire to be wound on the multiple winding arc rods 5.

[0023] Further, in order to facilitate the winding arc rod 5 to be unfolded or retracted with the movement of the screw sleeve 11, refer to Figure 2-3 As shown, the connecting member includes a first rotating seat 8, a connecting rod 9 and a second rotating seat 10 which are rotatably connected in sequence, the first rotating seat 8 is welded to the inner side of the end of the winding arc rod 5, and the second rotating seat 10 is welded to the screw sleeve 11. When the two screw sleeves 11 move on the driving member, the connecting rod 9 rotates between the first rotating seat 8 and the second rotating seat 10, which can drive the multiple winding arc rods 5 to expand outward or close inward.

[0024] Further, in order to facilitate the clamping of the end of the spring wire on the winding arc rod 5, refer to Figure 1-4 As shown, a slot 4 is provided on the outer wall of each winding arc rod 5 in the axial direction, and one end of the slot 4 extends through and extends to the side of the winding arc rod 5 away from the rotating disk 3.
