DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-3 The four-claw nut processing and forming device comprises a processing table 1, a support plate 2 is fixedly installed at the bottom of the processing table 1, a placement groove 3 is arranged on the right side of the processing table 1, the placement groove 3 is a semi-finished round bottom nut placement dish, a finished product slide groove 4 is installed on the left side of the processing table 1, four pillars 5 are fixedly installed on the upper side of the processing table 1, a transverse groove 6 is fixedly installed on the upper end of the pillar 5, a slider 7 is slidably installed on the inner side of the transverse groove 6, a threaded rod 10 is rotatably installed on the inner side of the transverse groove 6 and the threaded rod 10 is screwed through the slider 7, a motor 11 is fixedly installed on the outer side of the transverse groove 6, the output end of the motor 11 rotates through the inner side of the transverse groove 6 and the output end of the motor 11 is connected to the threaded rod 10 by a shaft coupling, a cylinder 12 is fixedly installed at the bottom of the slider 7, a mounting seat 13 is installed on the output end of the cylinder 12, a punching knife 16 is fixedly installed at the bottom of the mounting seat 13, an electromagnetic block 17 is embedded in the mounting seat 13, and a punching seat 18 is installed at the position corresponding to the mounting seat 13 on the processing table 1.

[0024] Through the above structure, by energizing the electromagnetic block 17, the electromagnetic block 17 can generate a magnetic attraction. Since the electromagnetic block 17 is embedded in the mounting seat 13, the bottom of the mounting seat 13 can generate a magnetic attraction when the electromagnetic block 17 is energized. At the same time, the nut is a steel product and can be adsorbed on the bottom of the mounting seat 13 under the action of magnetic force. This setting is used for the mounting seat 13 to take and place the nut. When the electromagnetic block 17 is energized, it is absorbed. When the electromagnetic block 17 is de-energized, the magnetic attraction is lost, and the nut slides off by itself under the action of its own weight.

[0025] In this embodiment, the finished product chute 4 is arranged in an inclined shape.

[0026] Through the above structure, the finished product chute 4 is set in an inclined shape. Under the action of its inclined surface, when the four-claw nut after production slides onto the finished product chute 4, it can slide along the inclined surface of the finished product chute 4 into the corresponding collection device.

[0027] In this embodiment, a clamping block 9 is fixedly installed on the side of the sliding block 7 , a clamping groove 8 is opened inside the transverse groove 6 , and the clamping block 9 is slidably clamped inside the clamping groove 8 .

[0028] Through the above structure, when the slider 7 slides along the inner side of the transverse groove 6 driven by the threaded rod 10, the blocks 9 on both sides of the slider 7 slide synchronously on the inner side of the groove 8, thereby improving the stability of the slider 7 during movement, that is, strengthening the stability of the bottom support structure of the cylinder 12, thereby improving the stability of the device during operation.

[0029] In this embodiment, three first ear seats 14 are fixedly installed on the side of the mounting seat 13, and the first ear seats 14 are provided with first bolts 15. The mounting seat 13 is screwed on the output end of the cylinder 12 through the first ear seats 14. Three second ear seats 21 are fixedly installed on the side of the punching seat 18, and the second ear seats 21 are provided with second bolts 22. The punching seat 18 is screwed on the processing table 1 through the second ear seats 21.

[0030] Through the above structure, the mounting seat 13 and the punching seat 18 are both arranged to be screwed and installed, and the punching knife 16 is fixedly installed at the bottom of the mounting seat 13, so it is convenient to replace the matching punching knife 16 and the punching seat 18. This setting is used to meet the production requirements of four-claw nuts of different sizes, thereby improving the applicability of the utility model.

[0031] In this embodiment, four punching knives 16 are evenly distributed along the mounting seat 13 and are made of high-strength alloy steel. A circular hole 19 is opened in the middle position of the punching seat 18. The inner diameter of the circular hole 19 is larger than the outer diameter of the bearing seat in the semi-finished round bottom nut. The punching seat 18 is opened with a punching opening 20 corresponding to the position of the punching knife 16.

[0032] Through the above structure, the punching blade 16 is set to a high-light alloy steel, which improves the strength and toughness of the punching blade 16, avoids the punching blade 16 from breaking during punching, and increases the service life of the punching blade 16.

[0033] In the utility model, when in use, the motor 11 is started to drive the threaded rod 10 to rotate, and the screw connection transmission effect of the threaded rod 10 is used to drive the slider 7 to drive the mounting seat 13 on the output end of the cylinder 12 to move to the upper side of the placement groove 3, and the cylinder 12 is started to lower the mounting seat 13 to the inside of the placement groove 3, and then the electromagnetic block 17 is started to make the mounting seat 13 produce a magnetic attraction, so that the semi-finished round bottom nut inside the placement groove 3 is absorbed on the mounting seat 13, and then the cylinder 12 is retracted, and then the motor 11 is started to drive the mounting seat 13 to move to the top of the punching seat 18, and the cylinder 12 starts the downward punching effect, and the semi-finished round bottom nut is placed on the punching seat 18 while continuing to move downward, and the outer side of the semi-finished round bottom nut is punched. The punching action is performed, and four corner seats are formed on the outside of the semi-finished round bottom nut while the punching knife 16 enters the inside of the punching opening 20, that is, the punching and forming of the four-claw nut is completed. Subsequently, the cylinder 12 is started to contract. Since the electromagnetic block 17 inside the mounting seat 13 is still in a working state, the four-claw nut after punching and forming is driven and adsorbed on the mounting seat 13 under the action of magnetic attraction. Subsequently, the motor 11 is started to drive the mounting seat 13 to move above the finished product chute 4, and then the electromagnetic block 17 is powered off, the mounting seat 13 loses its magnetic attraction, and the four-claw nut slides onto the finished product chute 4 under the action of its own weight, and slides along the finished product chute 4 to the corresponding collection device, thus completing the fully automatic production and processing process of the four-claw nut.
