Description

Technical Field

[0001] The utility model relates to a wire feeding frame for a spring machine, belonging to the technical field of spring production devices. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. It is usually made of spring steel wire by a spring machine. When making springs, a spring machine needs to use a wire feeder to assist in feeding the spring steel wire coil to cooperate with the automated production of the spring machine.

[0003] The Chinese utility model patent with announcement number CN218503231U proposes a "synchronous wire feeding frame for a spring machine", which includes a bracket, a box, a turntable and multiple pay-off frames. The box is fixedly arranged on the top of the bracket, and a first motor is fixedly provided inside the box. The output end of the first motor is fixedly provided with a first rotating shaft. The upper end of the first rotating shaft extends to the outside of the box and is fixedly connected to the turntable. Multiple pay-off frames are evenly distributed around and arranged on the top of the turntable. The bottoms of the multiple pay-off frames are fixedly provided with a second rotating shaft connected to the turntable for rotation. The tops of the multiple pay-off frames are provided with a downward pressure mechanism; the side walls of the box are fixedly provided with a support plate, the top of the support plate is fixedly provided with a cylinder, the end of the piston rod of the cylinder is fixed with a second motor, and the end of the output shaft of the second motor is fixed with an insert. The utility model can quickly switch and install the wire reels, shorten the time for the spring machine to stop feeding, and thus improve the working efficiency of the spring machine.

[0004] Research has revealed that the aforementioned patent places multiple pay-offs on the turntable, requiring the placement of wire reels on each of these pay-offs to achieve rapid reel switching. However, placing wire reels on multiple pay-offs increases the weight of the turntable, which acts directly on the first motor via the first rotating shaft. This accelerates the wear and tear of the first motor, directly impacting its service life. Therefore, the present invention proposes a spring machine wire feeder to address this issue.

[0024] In the above technical solution, a spring machine wire feeding frame of the utility model is provided with grooved plates 7 at the four corners of the top of the box body 2, a U-shaped wheel frame 8 is fixedly connected to the top of the grooved plate 7, and an auxiliary wheel 9 rotatably connected to the U-shaped wheel frame 8 is abutted against the bottom of the protruding ring 6 provided at the bottom of the turntable 5, so that when multiple discharge trays 21 are placed with wire rings in the utility model, a multi-point balanced support effect is played, which protects the motor 3 and will not accelerate the service life loss of the motor 3, thereby further ensuring the service life of the utility model.

[0025] Through holes 10 are formed on both sides of the U-shaped wheel frame 8 on the plurality of grooved plates 7. A set of threaded holes 11 are formed at the four corners of the top of the box body 2. Each through hole 10 corresponds to the threaded hole 11. Bolts 12 are passed through the through holes 10 and threadedly engaged with the threaded holes 11. The grooved plates 7 are fixedly connected to the top of the box body 2 through the threaded connection between the bolts 12 and the threaded holes 11. The threaded connection between the bolts 12 and the threaded holes 11 allows the grooved plates 7 to be detachably connected to the top of the box body 2, making it easier to replace the auxiliary wheels 9 if they are damaged.

[0026] The top of the turntable 5 is provided with a plurality of bearing grooves 13 in a circumferential shape. The bottom of the bearing grooves 13 is provided with a through-hole 14. Bearings are installed in the bearing grooves 13. A rotating shaft 15 is installed in the inner ring of the bearing. The top of the rotating shaft 15 is higher than the top of the turntable 5, and a first pulley 16 is installed on the portion of the rotating shaft 15 that is higher than the top of the turntable 5.
