Description

Technical Field

[0001] This utility model relates to the field of metal spring processing technology, and in particular to a precision winding device for metal springs. Background Technology

[0002] Metal springs come in many varieties, and can be classified into tension springs, compression springs, torsion springs, and bending springs according to the nature of the force applied. Metal springs play a vital role in machines and instruments. They can control the movement of machine parts, dampen shocks or vibrations, store energy, and measure the magnitude of force. They are widely used in automobiles, machinery, electronic products, electrical appliances, stationery, power switches, micro switches, construction, daily necessities, home appliances, and A / V equipment, among other fields. A winding device is required during the processing of metal springs.

[0003] Announcement No. CN221909574U discloses a spring winding device, relating to the field of spring processing technology. The device includes a base with a first mounting bracket and a second mounting bracket. The first and second mounting brackets have pre-set mounting holes. A threaded sleeve is fixed inside each mounting hole. A threaded rod is threadedly connected inside the threaded sleeve. A groove is provided at the end of the threaded rod away from the threaded sleeve. A clamping rod is provided inside the groove. A pressing rod is provided on the clamping rod. Spring material is wound around the end of the threaded rod away from the threaded sleeve. In this invention, the operator inserts the clamping rod into the groove and rotates the clamping rod, thereby driving the threaded rod to rotate within the threaded sleeve. Simultaneously, vertical spring material is placed between the pressing rod and the threaded rod. The spring material is compressed by the rotation of the pressing rod, thus being wound into a spring product.

[0004] However, similar to the metal spring precision winding device mentioned above, the diameter of the winding rod cannot be adjusted during use. When the diameter of the winding spring needs to be adjusted, the winding rod needs to be disassembled and reinstalled, which is cumbersome and inconvenient to use. Utility Model Content

[0012] The present invention is further configured such that a connecting block is fixedly connected to one end of the mounting bracket, a connecting hole is provided on one side of the connecting block, and connecting pipes are fixedly provided at both ends of the connecting hole.

[0013] The present invention is further configured such that an installation groove is provided on the inner wall of the connecting hole, and rotating wheels are rotatably connected to the inner walls of both ends of the installation groove.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. In use, the metal spring precision winding device involves threading a metal wire through a connecting hole and connecting pipe, and limiting the wire's position using a stop block and a slot. Then, the first motor is started, driving the connecting rod and winding rod to rotate. Simultaneously, an electric push rod pushes the mounting bracket to move on the slide rail, causing the metal wire to wind onto the winding rod and form a spring. Finally, an electric shears cuts the metal wire. When adjusting the diameter of the metal spring, the bidirectional threaded rod can be rotated, driving two frustum-shaped push blocks to move towards each other. Under the action of the slider and the slide groove, this drives two connecting plates to move outward, which in turn drives the arc-shaped winding plate to move outward, increasing the diameter of the winding rod and thus adjusting the diameter of the metal spring.

[0019] 2. This metal spring precision winding device allows for the rotation of a knob when the bidirectional threaded rod is rotated. The knob drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the bidirectional threaded rod to rotate. The speed reduction structure of the worm wheel and worm gear increases the accuracy of the winding rod diameter adjustment.

[0020] 3. This metal spring precision winding device uses a second motor to drive a rotating wheel to rotate, thereby driving the metal wire to move and facilitating the conveying of the metal wire. Attached Figure Description
