Description

Technical Field

[0001] The invention relates to the technical field of hardware production, and in particular to a nut gasket production device and a production method thereof. Background Art

[0002] In the metal processing industry, the manufacture of nut washers is a key production link. Nut washers are usually used between connecting parts to ensure the stability and safety of the fastening connection. The production of traditional nut washers usually starts with rolled blanks. During the curling and storage process, these blanks will deform to a certain extent due to external forces such as winding tension, storage pressure and temperature fluctuations. This deformation causes stress to accumulate inside the blank, so there are certain defects in the handling and stamping of the blank.

[0003] First, the accumulated stress will cause uneven deformation of the blank during the stamping process. Due to the uneven distribution of stress, the reaction speed and deformation degree of each part of the blank will be different when it is subjected to the stamping force. Uneven deformation not only affects the shape accuracy of the gasket, but may also cause dimensional deviation and reduce product quality.

[0004] Secondly, the presence of stress increases the risk of blank rupture during stamping. When the blank is subjected to excessive stamping pressure, the area where stress is concentrated is more likely to rupture, resulting in an increase in the scrap rate. This not only increases production costs, but also reduces production efficiency.

[0039] It should be noted that the side of the pressure plate 34 is fixed to the inner side of the leveling frame 31, and the top is in contact with the inner side of the top of the conveyor belt 32; the heating layer 35 is heated by heat conduction or heat radiation; the control system is electrically connected to the feeder 2, the punching machine 4, the winder 5 and the heating layer 35 respectively; the control method of the control system and the control circuit for realizing full-automatic nut gasket production are realized by a programmable controller, which belongs to the prior art and can be realized by programming by technicians in this field. It belongs to the common knowledge in this field, so this application will not explain the control method and module in detail, and will not be described in detail here; through the control system, the feeder 2, the leveling mechanism 3, the punching machine 4 and the winder Machine 5 realizes fully automatic gasket processing, ensuring the continuity and automation of the production process. The conveyor belt 32 in the leveling mechanism 3 is used to transport the blank. Through the cooperation of the lifting and holding components, the pressure block 33 is driven to apply and maintain uniform downward pressure on the blank on the leveling frame 31. The pressure plate 34 supports the conveyor belt 32 and the blank, which can effectively eliminate the internal stress accumulated in the blank during curling and storage, making the material more uniform and stable. The heating layer 35 is used to heat the blank to further eliminate the stress and relax the blank, ensuring the uniformity and stability of the blank before stamping, thereby reducing deformation or cracking caused by stress concentration during the stamping process and improving the shape and dimensional accuracy of the stamped product.

[0040] In some embodiments, the rear-stage leveling assembly includes: an ultrasonic generator 311 installed on the top of the base 1, an amplitude plate 312 fixed on the inner side of the leveling frame 31, and a plurality of piezoelectric transducers 313 installed on the bottom of the amplitude plate 312; the top of the amplitude plate 312 contacts the inner side of the top of the conveyor belt 32 and is located on one side of the pressure plate 34; the control system is electrically connected to the ultrasonic generator 311, and the ultrasonic generator 311 is electrically connected to the plurality of piezoelectric transducers 313.

[0041] It should be noted that the model of the ultrasonic generator 311 is preferably a Sonikks generator; after the front stage leveling of the blank is completed, the ultrasonic generator 311 is controlled by the control system to transmit the sound waves to a number of piezoelectric transducers 313. After the piezoelectric transducers 313 receive the sound waves, they can convert electrical energy into mechanical energy using the piezoelectric effect. The amplitude plate 312 transmits the vibration to the blank, which can penetrate the high-frequency vibration into the interior of the blank, so that the internal stress gradually releases the residual stress during the vibration process, further eliminating subtle stress points and uneven areas, and improving the flatness of the blank.

[0042] In some embodiments, the rear-stage leveling assembly also includes: a mounting plate 314 disposed on the top of the conveyor belt 32 on one side of the pressure block 33, a plurality of atomizing nozzles 315 mounted on the top of the mounting plate 314, and a fixing plate 316 fixed on one side of the mounting plate 314; one side of the fixing plate 316 is fixed to one side of the leveling frame 31, and the plurality of atomizing nozzles 315 are located on the top of the amplitude plate 312.

[0043] It should be noted that the input end of the atomizing nozzle 315 is connected to the water pipe of the external water delivery equipment; when ultrasonic high-frequency vibration is applied to the blank, the water pipe of the water delivery equipment is used to evenly spray water mist on the surface of the blank through the atomizing nozzle 315. The water mist is combined with the ultrasonic vibration to generate high-frequency excitation, so that jets and tiny bubbles are generated between the liquid on the surface of the blank, and the liquid and bubbles are sheared at high speed to generate instantaneous energy release, which can more effectively transmit vibration energy. At the same time, water molecules can reduce the heat and deformation generated by friction, further improving the leveling effect.

[0044] In some embodiments, the lifting and holding assembly includes: a support frame 6 installed on the top of the base 1, an upper cylinder 61 fixed on the top of the support frame 6, and a lower cylinder 62 fixed on the bottom of the support frame 6; the output ends of the upper cylinder 61 and the lower cylinder 62 are both equipped with a pushing block 63, and one side of the pushing block 63 is slidably connected to the side of the pressure block 33; the control system is electrically connected to the upper cylinder 61 and the lower cylinder 62 respectively.

[0045] It should be noted that, by respectively arranging an upper cylinder 61 and a lower cylinder 62 at the top and bottom of the support frame 6, when driving the bottom of the pressure block 33 to apply pressure to the surface of the blank, the control system is used to control the upper cylinder 61 to push the pushing block 63 downward, and control the lower cylinder 62 to drive the pushing block 63 to move downward synchronously, thereby ensuring that the pressure block 33 maintains a stable lifting process.

[0046] In some embodiments, the lifting and holding assembly also includes: a middle cylinder 64 and a holding plate 65 fixed on the side of the support frame 6 facing the leveling frame 31, a resistance block 66 installed at the output end of the middle cylinder 64, and a linear guide rail 67 fixed on the top of the holding plate 65; one side of the resistance block 66 resists against one side of the pressure block 33, a support block 68 is fixed to the bottom of the resistance block 66, and the bottom of the support block 68 is slidably connected to the top of the linear guide rail 67; the control system is electrically connected to the middle cylinder 64.

[0047] It should be noted that after controlling the pressure block 33 to rise and fall to the pressure posture at the top of the blank, the control system is used to control the middle cylinder 64 to push the resistance block 66 at the output end to move to the side of the pressure block 33, so that the linear guide 67 at the top of the holding plate 65 can achieve smooth limited sliding, and then the resistance block 66 is used to resist one side of the pressure block 33 to maintain the pressure state of the pressure block 33, thereby further enhancing the pressure uniformity and stability of the pressure block 33 and improving the leveling effect.

[0048] In some embodiments, the power assembly includes: a plurality of power rollers 7 arranged on the inner side of the leveling frame 31, a motor 71 installed at the bottom of the leveling frame 31, and a driving synchronous pulley 72 fixed to the output end of the motor 71; a driven synchronous pulley 73 is fixed to the side of the power roller 7, and a plurality of toothed belts 74 are meshed between the driving synchronous pulley 72 and the driven synchronous pulley 73.
