Second embodiment

As shown in fig. 8, based on the thread rolling machine convenient for cleaning waste provided by the first embodiment, in actual use, thread rolling is performed on both sides of the thread rolling plate 10, so that the device cannot be adaptively changed when tapping screws with different diameters, the feeding distance of the feeding block 23 is relatively different when feeding the screws with different diameters, and if the waste cannot be timely cleaned after the thread rolling on both sides of the thread rolling plate 10, the thread rolling plate 10 is damaged and the following screw thread rolling process is affected, in order to solve the problem, the thread rolling machine convenient for cleaning waste further includes: electromagnets are arranged on two sides of the inner surface of the sliding chute 9, the electromagnets control the size and the direction of magnetic force generated by the electromagnets by controlling the size and the direction of internal electrified current, a plurality of groups of compression springs 32 are uniformly arranged on the other ends of the electromagnets in an array manner, the elastic coefficients of the compression springs 32 are different, magnetic clamping plates 31 are arranged on the other ends of the compression springs 32, the magnetism of the two opposite magnetic clamping plates 31 is the same as that of the two magnetic clamping plates 31, and the magnetic force generated by the electromagnets is the same as that of the magnetic clamping plates 31, so that the magnetic clamping plates 31 which can generate magnetic repulsion force by the electromagnets can ensure the gap between the electromagnets and the screw plate 10, when the screw plate 10 returns in the idle stroke after the thread rolling is completed, the electromagnets are powered off, the magnetic repulsion force of the electromagnets disappears, and the two opposite magnetic clamping plates 31 move towards the electromagnet ends by virtue of the magnetic repulsion force of the electromagnets and the elastic contraction force of the compression springs 32 in the continuous return stroke process of the screw plate 10, simultaneously because compression spring 32's coefficient of elasticity is different, consequently it can constantly take place to rock at magnetism splint 31 return stroke in-process, can be shaken down along with this the waste material of gluing at magnetism splint 31 terminal surface of rocking, falls to the base 1 top again, and the magnetic repulsion that the electro-magnet produced will be much bigger for the elastic tension that compression spring 32 deformation produced, consequently compression spring 32's elastic force can be ignored when the electro-magnet is worked.

The magnetic clamping plate 31 is provided with a plurality of pressure sensors in uniform array on one side close to the screw plate 10 for detecting the pressure value of the compression screw, the top of the two magnetic clamping plates 31 is provided with an elastic arch plate 33, the elastic arch plate 33 is arched, the bottom of the elastic arch plate 33 is symmetrically provided with two groups of elastic brushes 34, the elastic arch plate 33 can deform along with the reciprocating movement of the magnetic clamping plate 31, when the magnetic clamping plate 31 moves towards the end of the screw plate 10 for extrusion tapping, the elastic arch plate 33 is arched and upwards moves, the elastic brushes 34 are synchronously driven to upwards move to be separated from the gap between the magnetic clamping plate 31 and the screw plate 10, a channel is given for the thread rolling, when the thread rolling plate 10 returns after the tapping is completed, the magnetic repulsion force borne by the magnetic clamping plate 31 disappears, the magnetic clamping plate 31 moves towards the electromagnet end relatively, the radian of the elastic arch plate 33 is increased, so that the top of the elastic arch plate moves downwards to drive the elastic brushes 34 to synchronously move downwards, the two sides and the gaps of the screw plate 10 are cleaned by means of the cleaning performance of the elastic brushes 34, at the moment, the screw plate 10 is in a return stroke stage, the bristles of the elastic brushes 34 are driven by the screw plate 10 to tilt upwards, when the screw plate 10 is completely separated from the elastic brushes 34, the two ends of the screw plate 10 are cleaned, the upwards-tilted brushes are released to swing downwards continuously, fine impurities in air can be adsorbed by means of the vibration, waste materials falling on the top of the base 1 can fall into the recycling box quickly, the situation that the waste materials are adhered to the top of the base 1 and are inconvenient to clean is avoided, and meanwhile, the vibration can be matched with the vibration of the magnetic clamping plate 31 to vibrate and clean the waste materials adhered to the end face of the magnetic clamping plate.

One side of the fixed plate 2 is provided with a controller, the controller is electrically connected with each electrical element, and the controller is mainly used in the control process, in order to feed and compress screws with different diameters for tapping, the rotation time of the electromagnet and the driving motor 16 is controlled by means of the pressure value of the pressure sensor on the end surface of the magnetic clamping plate 31, when the detected pressure value reaches the set pressure threshold value, the electromagnet does not further increase the current amount, the gap between the magnetic clamping plate 31 and the screw plate 10 can be ensured to meet the tapping requirement on the screws by keeping the current amount, and meanwhile, the rotation time of the driving motor 16 is controlled by means of the pressure value, so that the moving distance of the material supply block 23 is ensured, and the screw on one side of the material supply block 23 can be ensured to be tightly attached to the side surface of the screw plate 10 to enter a tapping area for working.

When the tapping machine is used, in order to adapt to the screws with different diameters to perform tapping work, because the base 1 is obliquely placed, the screw to be tapped is placed into the feeding chute 11, the screw falls into the material guide chute 12 by virtue of self gravity, at the moment, the diameter of the screw is not determined, the rotating speed of the driving motor 16 is not changed, the driving motor 16 drives the connecting shaft 17 to rotate, the connecting shaft 17 drives the first gear 18 to rotate, the first gear 18 is meshed with the second gear 19 to rotate so as to drive the threaded sleeve rod 20 to rotate, the threaded sleeve rod 20 rotates the threaded rod 21 in threaded connection in the limiting sleeve 30 to synchronously move inwards, so that the connecting plate 22 at the end part drives the material supply block 23 to move in the material guide chute 12 and drives the screw to move to two ends of the thread rolling plate 10, at the moment, the power motor 4 is started to drive the rotating shaft 5 to rotate, the rotating shaft 5 drives the disc 6 to rotate, the disc 6 drives the short shaft 7 to move around the disc 6, the short shaft 7 drives the hinged connecting rod 8 to move, so that the screw plate 10 is driven to move downwards in the sliding groove 9, and the two side faces of the screw plate 10 can tap the screw rod.

When the screw plate 10 moves downwards, the electromagnet on one side of the chute 9 is electrified, magnetic force is generated in the electromagnet, the direction of the magnetic force is the same as that of the magnetic clamping plate 31, therefore, the electromagnet acts on the magnetic clamping plate 31 by means of magnetic repulsion force to move the magnetic clamping plate to the tapping surface of the screw plate 10, when the magnetic clamping plate 31 moves to the tapping surface of the screw plate 10 by means of magnetic repulsion force, the compression spring 32 in the electromagnet is stretched to generate elastic tension, but the elastic tension is much weaker than the magnetic repulsion force, which is not considered temporarily, the compression force is further exerted on a screw rod between the magnetic clamping plate 31 and the tapping surface of the screw plate 10 by means of magnetic repulsion force, the compression force can be detected by a pressure sensor on the end surface of the magnetic clamping plate 31, when the pressure value is larger than a set pressure threshold value, the electromagnet stops increasing the electrified current, the magnitude of the magnetic repulsion force is kept unchanged at the moment, so that the gap between the magnetic clamping plate 31 and the screw plate 10 is kept unchanged, the tapping effect of the screw plate 10 can be effectively guaranteed by means of pressing force applied to the screw by the magnetic clamping plate 31, the tapping efficiency is improved, meanwhile, the size of the gap between the magnetic clamping plate 31 and the screw plate 10 can be synchronously changed by the size of different electrifying currents of the electromagnet, so that the tapping of the screw rods with different diameters can be well realized, the adaptability of the device is improved, and the device can be guaranteed to perform tapping work more efficiently and orderly.

Through setting for different pressure sensor's pressure threshold, correspond and just can realize tapping the screw rod of different diameters, specifically as follows: the gap between the magnetic clamping plate 31 and the screw plate 10 required by the screws with different diameters is different when the screws with different diameters are threaded, so that the magnetic repulsion of the electromagnet on the magnetic clamping plate 31 and the common acting force of the elastic force generated by the compression spring 32 are different, therefore, when the screws with different diameters are threaded, the positions of the magnetic clamping plate 31 are different, the pressure threshold values set by the corresponding pressure sensors are different, and the magnitude of the electrified current of the electromagnet is different.

When the magnetic clamping plate 31 moves towards the screw plate 10, the elastic arch plate 33 at the top of the magnetic clamping plate 31 can arch towards the middle due to the arch design, and the elastic brush 34 at the bottom can be driven to move upwards synchronously during the arch, so that the elastic brush 34 can be separated from the gap between the magnetic clamping plate 31 and the screw plate 10, and the tapping cannot be influenced.

Meanwhile, when any diameter of screw rod needs to be tapped, the moving distance of the feeding block 23 in the guide chute 12 is different in the feeding process, but it is finally required to achieve that the screw rod is in close contact with the two side surfaces of the screw plate 10, at this time, after the first tapping of the screw rod, according to the magnitude of the electrified current of the electromagnet when the pressure value of the magnetic clamping plate 31 to the screw rod detected by the pressure sensor reaches the set pressure threshold, the forward rotation rate of the driving motor 16 can be directly and correspondingly changed, that is, when the diameter of the screw rod becomes small, in order to ensure that the screw rod can be tapped efficiently, the gap between the magnetic clamping plate 31 and the screw plate 10 becomes large, the electrified current required by the electromagnet becomes large, therefore, the rotation rate of the corresponding driving motor 16 becomes large synchronously, so that the moving stroke of the feeding block 23 in the guide chute 12 becomes large by the increase of the rotation rate of the driving motor 16 in the one-time feeding process, therefore, the screw can be always in close contact with two side faces of the screw plate 10 in the feeding process, which is summarized as that the electromagnet is driven by the change value of the electrified current to change the change value of the gap between the magnetic clamping plate 31 and the screw plate 10, the driving motor 16 is driven by the change of the rotation rate to drive the change value of the stroke movement of the feeding block 23 in the material guide chute 12 to be equal, so that the optimal movement process is the optimal movement process, namely the rotation speed of the driving motor 16 is increased along with the increase of the electrified current of the electromagnet, the change quantization formula can be obtained from a plurality of experiments, and is not repeated, so that the size of the electrified current of the electromagnet can be correspondingly controlled through the detection of the pressure sensor, the rotation speed of the driving motor 16 can also be synchronously controlled, the perfect matching of feeding and tapping is realized, and the tapping work can be efficiently and orderly completed together.

After the downward tapping process of the screw plate 10 is completed, the connecting rod 8 drives the screw plate 10 to move upwards to continue the reverse return stroke, at the moment when the return stroke starts, the electromagnet stops being electrified, the electromagnet loses the magnetic repulsion force to the magnetic clamping plate 31 at the moment, the magnetic clamping plate 31 is completely released, at the moment, because the magnetic forces of the oppositely arranged magnetic clamping plates 31 are the same, the opposite magnetic repulsion force can be generated, and the magnetic repulsion force applied to the magnetic clamping plate 31 along with the continuous rising of the screw plate 10 can be continuously increased from the bottom to the top, so that the two magnetic clamping plates 31 move to the side far away from the screw plate 10, the compression springs 32 inside the magnetic clamping plates 31 can contract because of being in a stretching state, the contraction can generate elastic tension to the magnetic clamping plates 31 in the direction of the side far away from the screw plate 10, but because the elastic coefficients of the plurality of the compression springs 32 are different, the elastic tension to the magnetic clamping plates 31 is different in magnitude when the same stretching amount, at the magnetic repulsion that magnetic splint 31 is relative that the cooperation was constantly released, then magnetic splint 31 can take place inhomogeneous and irregular rocking when continuing to retract to keeping away from thread rolling board 10 one side, can clear away the waste material of adhering at magnetic splint 31 terminal surface with the help of this process of rocking, guarantees that it is in a smooth level and smooth face that compresses tightly, guarantees the cleanliness factor of device, avoids causing the influence to subsequent processing.

Meanwhile, when the magnetic clamping plate 31 moves away from one side of the screw plate 10, the elastic arch plate 33 at the top of the magnetic clamping plate 31 moves downwards along with the magnetic clamping plate 31 in the process of moving towards two sides due to the arch design of the elastic arch plate 33, the elastic brush 34 is driven to be inserted into the gap between the magnetic clamping plate 31 and the screw plate 10 by virtue of the downward movement process of the elastic arch plate 33, and the elastic brush 34 can continuously clean the magnetic clamping plate 31, the screw plate 10 and waste materials in the gap between the magnetic clamping plate 31 and the screw plate 10; meanwhile, in the return stroke process of the screw plate 10, the screw plate 10 extrudes and deforms the elastic brush 34, the elastic brush 34 close to one side of the screw plate 10 is extruded upwards to incline, and when the screw plate 10 moves upwards continuously, the elastic brush 34 at the position is released to return to the vertical state again, so that the vibration generated in the process of rising upwards to returning again is utilized by the elastic brush 34, not only can the tiny impurities in the gap be adsorbed and cleaned, but also the waste at the top of the base 1 can be rapidly moved downwards to finally fall into a recycling box through downward swinging, so that the device can be reasonably and effectively cleaned by matching with the movement of the magnetic clamping plate 31, the cleanliness of the device is ensured, the working effect of the device is improved, and the tapping efficiency is ensured.
