Description

TECHNICAL FIELD

[0002] A thread rolling machine is a mechanical device used for processing threads, which rolls threads on the surface of metal wires or rods through a pair of rotating thread rolling plates or rollers, and is widely used in the mechanical manufacturing, construction, automobile and other industries for producing fasteners such as screws and bolts, and has the advantages of high production efficiency, high thread precision and good processing surface quality.

[0003] Among them, the thread rolling machine with circular motion is a device that uses rotational motion to process threads, and the thread rolling plate or thread rolling wheel performs circular motion around the center axis, and the surface of the blank is formed into threads through continuous rotation and extrusion, which has the advantages of high processing efficiency, good thread quality and compact device structure, and is widely used in large-scale production of threaded fasteners.

[0004] One of the feeding methods of the thread rolling machine is to use a vibrating disc to arrange and feed the bolt blanks in a certain order into the feeding chute, and then the blanks smoothly enter the thread rolling area along the chute. This feeding method can realize automatic feeding, effectively improve production efficiency, ensure continuous supply of blanks, reduce manual intervention, and ensure the stability and accuracy of feeding.

[0005] In the working process of the thread rolling machine with circular motion, the workpiece is conveyed to the thread rolling area by a linear feeding mechanism. If the feeding speed of the linear feeding mechanism is set too high, the workpiece may collide violently with the thread rolling tool that is rotating at high speed when it reaches the thread rolling area. This collision not only causes scratches, deformation and even breakage of the workpiece surface, but also causes the thread rolling tool to bear additional impact force, thereby increasing the degree of wear and tear of the tool, shortening the service life of the tool, and affecting the quality of the entire thread rolling process.

[0017] A method for using a thread rolling machine with a bidirectional feeding mechanism;

[0018] Step 1: When realizing bidirectional loading, the two vibrating plates transport the workpiece to the inside of the conveying track respectively, and the workpiece falls into the inside of the hollow cylinder shell through the semi-through slot. The bottom end of the workpiece contacts multiple spring plates, and the upper part of the workpiece blocks the semi-through slot. The servo electric cylinder is started, and the servo electric cylinder drives the movable plate and the pressure barrel to move downward. The pressure barrel moves downward to squeeze the workpiece inside the hollow cylinder shell. The lower part of the workpiece squeezes the spring plate, and the lower end of the workpiece slides smoothly between the frame plate, the arc baffle and the arc push plate. The workpiece is pushed out from between the multiple spring plates, and the spring plate moves inside the fixed port. The servo motor is started to drive the cross plate to rotate, and the cross plate drives the arc connecting rod and the pusher assembly to rotate, pushing the workpiece to between the thread rolling disk and the fixed thread rolling plate;

[0019] Step 2: When improving the integrity of the workpiece during loading, the arc-shaped connecting rod pushes the arc-shaped push plate to move, and the arc-shaped push plate pushes the workpiece to move. The workpiece will contact the adjustment component, and one end of the torsion spring will slide inside the movable groove. The workpiece will contact the rubber strip, and the rubber strip will deform. At this time, the workpiece will rotate, and the rotating drum will rotate with the workpiece. When the workpiece rotates along the rubber strip, the rubber strip will deform in the direction of the inclined groove, exerting a downward force on the workpiece. When the workpiece moves to the thread rolling area of ​​the thread rolling disk and the fixed thread rolling plate, the workpiece is squeezed between the thread rolling disk and the fixed thread rolling plate;

[0020] Step 3: When the workpiece is efficiently rolled, the drive motor is started to drive the worm to rotate, and the worm drives the two meshing turbines to rotate in the same clockwise direction at the same time. The turbine drives the roller to rotate, and the roller is connected to the inside of the machine, and the roller drives the thread rolling disk to rotate;

[0021] Step 4: When replacing wearing parts, remove the fixing screws, separate the arc baffle from the machine, fix the arc baffle to the machine with the fixing screws, remove the short threaded rod, disengage the short threaded rod from the inside of the solid column hole, move the correction plate in the opposite direction of the torsion spring, disengage the torsion spring from the inside of the movable groove, align the movable groove with the torsion spring and insert it, align the shaft hole with the solid column hole, insert the short threaded rod into the solid column hole and the shaft hole, extend the short threaded rod out of the lower end of the accommodating groove, and the thread of the short threaded rod is spirally installed with the solid column hole, and the short threaded rod is embedded in the inside of the solid column hole.

[0059] Working process: When bidirectional loading is realized, the two vibrating plates 4 convey the workpieces to the inside of the conveying track 29 respectively. The conveying track 29 is used to guide the workpieces from the vibrating plate 4 to the semi-through slot 28, and then drop into the inside of the hollow cylinder shell 25 through the semi-through slot 28. Initially, the pressing cylinder 24 is at the upper part of the hollow cylinder shell 25. At this time, the bottom end of the workpiece contacts multiple spring plates 27, and the upper part of the workpiece blocks the semi-through slot 28 to prevent the next workpiece from falling. At this time, the servo electric cylinder 21 is started, and the servo electric cylinder 21 drives the moving plate 22 and the pressing cylinder 2 4 moves downward, and the spacing between the pressing cylinder 24 and the hollow cylindrical shell 25 can prevent the workpiece to be processed from protruding from the interior of the hollow cylindrical shell 25, which makes the pressing cylinder 24 unable to move. The pressing cylinder 24 moves downward to squeeze the workpiece inside the hollow cylindrical shell 25. Under the action of squeezing, the lower part of the workpiece opens the spring plate 27. Under the elastic force of the multiple spring plates 27, the downward movement direction of the lower end of the workpiece can be controlled, so that the lower end of the workpiece can slide smoothly between the frame plate 351, the arc-shaped baffle 34 and the arc-shaped push plate 331 until the workpiece is pushed out from the multiple spring plates 27. The top of the frame plate 351, the top of the arc baffle 34 and the top of the arc push plate 331 are all flush structures, which can horizontally support the large end of the workpiece. When the servo motor 19 is started to drive the horizontal plate 31 to rotate, the horizontal plate 31 drives the arc connecting rod 32 and the push assembly 33 to rotate, and the axis of the servo motor 19 is aligned with the arc baffle. The center of the plate 34 is aligned with the vertical line, so that when the pusher assembly 33 rotates, the gap between the pusher assembly 33 and the arc-shaped baffle 34 remains unchanged, and finally the workpiece is pushed between the thread rolling disk 16 and the fixed thread rolling plate 17 to realize the work of loading the workpiece. According to the above working principle, the device is provided with a two-way feeding structure to supply two thread rolling processing mechanisms, which meets the requirements of efficient processing. During the loading process, the stability of the workpiece loading can be improved, the failure during loading can be reduced, and at the same time, a basis for improving the processing efficiency of the workpiece is provided;

[0060] When improving the integrity of the workpiece during loading, the same principle as above is used. When the arc-shaped push plate 331 is pushed to move by the arc-shaped connecting rod 32, the arc-shaped push plate 331 will push the workpiece to move, and the workpiece will contact the adjustment component 357. Under the elastic torsion force of the torsion spring 356, the tightness of the fit between the workpiece and the adjustment component 357 can be improved. During this period, one end of the torsion spring 356 will slide inside the movable groove 3577, and the correction plate 3571 will be rotated and connected between the shaft hole 3575 and the short threaded rod 354, and the positioning column 353 and the correction component 357 will be rotated and connected. There is a movable spacing between the plates 3571, which does not affect the rotation of the correction plate 3571 into the receiving groove 352. When the workpiece contacts the rubber strip 3573, the rubber strip 3573 is deformed. At this time, the friction between the workpiece and the rubber strip 3573 is greater than the friction between the workpiece and the arc baffle 34. At this time, the workpiece will rotate, and the rotating drum 336 will rotate with the workpiece to reduce the friction when the workpiece rotates. By controlling the rotation speed of the main shaft of the servo motor 19, the rotation speed of the workpiece is controlled so that the rotation speed of the workpiece is consistent with the thread rolling disk. 16, when the workpiece rotates along the rubber strip 3573, due to the special shape of the rubber strip 3573, the rubber strip 3573 will be deformed in the direction of the inclined groove 3574. When the inclined groove 3574 is deformed, a downward force is applied to the workpiece. At the same time, the inclined groove 3574 gradually tilts downward in the direction close to the thread rolling disk 16. This can prevent the workpiece from moving upward during rotation, thereby improving the accuracy of the thread rolling position of the workpiece. When the workpiece moves to the thread rolling area of ​​the thread rolling disk 16 and the fixed thread rolling plate 17, the second The opening of the arc groove 333 does not affect the contact between the thread rolling disk 16 and the workpiece, so that the workpiece is squeezed between the thread rolling disk 16 and the fixed thread rolling plate 17, thereby achieving the purpose of thread rolling the workpiece. According to the above setting principle, the device can make the workpiece itself rotate in the same direction before entering the processing area between the thread rolling disk 16 and the fixed thread rolling plate 17, and at the same time match the rotation speed, significantly reducing the impact on the service life of the thread rolling disk 16 due to collision between the workpiece and the high-speed rotating thread rolling disk 16 during loading, and at the same time improving the qualified rate of the finished workpiece;

[0061] When the workpiece is efficiently rolled, after the workpiece is loaded, the drive motor 12 is started to drive the worm 13 to rotate, and the worm 13 drives the two meshing turbines 14 to rotate in the same clockwise direction at the same time, and the turbine 14 drives the roller 15 to rotate, and the roller 15 is connected to the inside of the machine 11, and the roller 15 drives the rolling disc 16 to rotate. At this time, the rotation direction of the two rolling discs 16 is the same. Due to the different loading positions, the finished products rolled out by the rear end rolling disc 16 and the fixed rolling plate 17 are discharged to the right, and the finished products at the front end are discharged to the left, so as to prevent the finished products from interfering with each other. This rolling method improves the rolling efficiency and is suitable for large-scale rolling work.

[0062] When replacing wearing parts, since the workpiece will contact the arc baffle 34, the contact surface of the arc baffle 34 will be subjected to friction, so it needs to be replaced regularly. By disassembling the fixing screws 36, the arc baffle 34 can be separated from the machine table 11, and the intact arc baffle 34 can be fixed to the machine table 11 by the fixing screws 36, ensuring that the fixing screws 36 are embedded in the inside of the embedded screw holes 37 to prevent the large head of the workpiece from contacting the fixing screws 36. When replacing the adjustment component 357, the short threaded rod 354 is disassembled, and the short threaded rod 354 is detached from the inside of the fixed column hole 355, and the correction plate 3571 is moved to the 35. The torsion spring 356 moves in the opposite direction. At this time, the torsion spring 356 is disengaged from the movable groove 3577. The intact adjustment assembly 357 is replaced. The movable groove 3577 is aligned with the torsion spring 356 and inserted. The shaft hole 3575 is aligned with the solid column hole 355. The short threaded rod 354 is inserted into the solid column hole 355 and the shaft hole 3575. The short threaded rod 354 extends out of the lower end of the accommodating groove 352. Then the thread of the short threaded rod 354 is spirally installed with the solid column hole 355 until the short threaded rod 354 is embedded in the solid column hole 355 without hindering the movement of the workpiece. The replacement of the wearing parts can be completed.
