The invention will be further described with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 to 2, a feeding mechanism of a nut forming machine according to this embodiment includes a feeding main body 1, the feeding main body 1 is rotatably connected to a lower main shaft 2 having two ends respectively extending out of front and rear end surfaces of the feeding main body 1, one end of the lower main shaft 2 is provided with a lower pressing wheel 3, the feeding main body 1 is provided with a slider hole 4 located above the lower main shaft 2, the slider hole 4 laterally penetrates through the feeding main body 1, a slider 5 sliding up and down is embedded in the slider hole 4, the slider 5 is rotatably connected to an upper main shaft 6 having two ends respectively extending out of an orifice of the slider hole 4, one end of the upper main shaft 6 is provided with an upper pressing wheel 7 located above the lower pressing wheel 3, the slider hole 4 is further provided with a pressing block 8 pressed on the slider 5, the feeding main body 1 is threadedly connected to an adjusting screw 9 having a portion extending into the slider hole 4 and abutting against the pressing block 8, the feeding main body 1 is inserted with a damping screw 10, the part of the damping screw 10 extends into the sliding block hole 4 and penetrates through the pressing block 8, the end part of the damping screw 10 is in threaded connection with the sliding block 5, and the damping screw 10 is sleeved with a damping spring 11, one end of the damping spring is abutted to the tail part of the damping screw 10, and the other end of the damping spring is abutted to the upper end face of the feeding main body 1. Wherein, the damping screw 10 can move up and down relative to the feeding main body 1, and the damping screw 10 can move up and down relative to the pressing block 8.
Further, the other end of the lower spindle 2 is provided with a lower gear 12, the other end of the upper spindle 6 is provided with an upper gear 13 meshed with the lower gear 12, the outer side of the lower gear 12 is also provided with a first transmission wheel 14 coaxially arranged with the lower gear, the first transmission wheel 14 is meshed with a second transmission wheel 15, and the second transmission wheel 15 is connected with a motor 16 for controlling the rotation of the second transmission wheel. By operating the motor 16, the second driving wheel 15 is driven to rotate, the first driving wheel 14 which is meshed with the second driving wheel is driven to synchronously rotate, the upper gear 13 and the lower gear 12 are driven to reversely rotate, the rotation of the upper spindle 6 and the lower spindle 2 is realized, and finally, the reverse rotation of the upper pinch roller 7 and the lower pinch roller 3 is realized for conveying wires.
In this embodiment, firstly, the damping spring 11 is in a deformed state, in order to recover the deformation, the sliding block 5 screwed to the lower end of the damping screw 10 is pulled upwards, so that the sliding block 5 slides upwards relative to the sliding block hole 4, and the pressing block 8 is locked by the adjusting screw 9 because the pressing block 8 is pressed on the sliding block 5, and when the adjusting screw 9 is not rotated, the pressing block 8 is tightly attached to the sliding block 5 and cannot move up and down; when uneven linear materials are conveyed between the upper pressing wheel 7 and the lower pressing wheel 3 and are conveyed too tightly, if the conveying is affected, the adjusting screw 9 can be manually rotated to partially rotate out of the feeding main body 1, and under the common acting force of the linear materials and the damping spring 11, the sliding block 5 and the pressing block 8 move upwards relative to the sliding hole 4; if the transmission is too loose, the gap between the upper pressing wheel 7 and the lower pressing wheel 3 is too large, so that the traction force for grabbing the wire rod is insufficient, the adjusting screw 9 is manually rotated to partially screw the adjusting screw into the feeding main body 1, the adjusting screw 9 moves the abutted pressing block 8 and the sliding block 5 downwards relative to the sliding hole 4, the adjustment of the gap between the upper pressing wheel 7 and the lower pressing wheel 3 is completed, and the feeding and conveying are smooth.
Wherein, the adjusting distance between the upper pinch roller 7 and the lower pinch roller 3 is within a small adjusting range that the upper gear 13 and the lower gear 12 can still keep normal transmission.
Further, the number of pinch rollers 3 is two at least and all is in on the same vertical height, go up pinch roller 7 and pinch rollers 3's quantity the same, adopt multiunit wheelset to carry for carry steadily, the feed is smooth and easy.
Furthermore, set up respectively on the wheel face of pinch roller 3 and last pinch roller 7 down and be annular breach groove 17 for the wire rod that the embedding needs to pull avoids it in transmission process, drops between pinch roller 3 and last pinch roller 7 from pushing down, influences the wire rod and carries, has played the effect to the location of wire rod and supplementary transport.
Preferably, the bottom of the notch groove 17 is arc-surface shaped, and is matched with an arc-surface shaped wire rod, so that the wire rod is tightly attached, better grabbed, larger in traction force and not easy to derail.
Furthermore, the upper end and the lower end of the damping spring 11 are respectively abutted with a gasket 18 sleeved on the damping screw 10, so that the functions of supporting and pressure dispersing are achieved.
Preferably, the washer 18 is a flat washer.
The utility model relates to a feeding mechanism of nut forming machine, through the relative lower vertical height adjustable between the pinch rollers of upper pinch roller, realize the fine setting of distance between the two to this adaptation unreels out uneven straight line material, and suitably extrudees through flexible pneumatic cylinder, compensates the deformation, and offsets the drunkenness that produces the mechanism, makes the feed carry smoothly; the vertical height of the sliding block relative to the sliding block hole is changed by rotating the adjusting screw, so that the structure is simple and the adjustment is convenient; the sliding block and the butted pressing block are tightly attached to each other by matching the damping screw with the damping spring, so that collision and vibration are reduced in use, and transmission is stable; the whole transmission structure is not complicated, the use is flexible and convenient, the failure rate is low, the installation and the maintenance are convenient, the whole function is perfect, and the practicability is strong.
