Description

Technical Field

[0001] The present invention relates to the technical field of fastener processing equipment, and in particular to a forming device for producing fasteners for high-speed railways. Background Art

[0002] Cold heading of fasteners is a processing technology that applies external force to metal at room temperature to cause it to plastically deform in a predetermined mold to form fasteners (such as bolts, screws, nuts, etc.). This process has the advantages of high material utilization, high productivity, good mechanical properties, and suitability for automated production. It is a processing method widely used in fastener manufacturing.

[0003] In the cold forging of fasteners, mechanical power drives the stamping structure to stamp the metal material in the mold. This process requires cooling oil to cool down. The cooling oil will contain iron chips, which will affect the reuse and need to be filtered. However, the iron chips will accumulate in the filter holes during the filtration process, blocking the filter holes and affecting the filtration efficiency of the cooling oil.

[0004] For example: The Chinese utility model patent (application number: 202322031869.X) discloses a "multi-station cold heading forming device for producing high-strength and corrosion-resistant fasteners". Its specification discloses: Fasteners are a type of mechanical parts used for fastening and connection and are extremely widely used, including bolts, nuts, etc. After the bolts and nuts are cold headed, they are heat treated and galvanized to obtain high-strength and corrosion-resistant fasteners. When the fasteners are cold headed, a cold heading machine is generally used, and cooling oil is also required to cool the processing part of the cold heading machine. The cooling oil contains impurities, and the impurities need to be separated from the cooling oil. In the prior art, for example, the patent application number is CN202222721210.2, and the patent name is a patent for a recovery and separation device for cooling oil of a nut cold heading machine. The patent mainly filters the cooling oil through the filter screens on the first filter cover and the second filter cover. The rust slag and iron debris can be gradually filtered out through the filter mesh of the filter screen, and the electromagnetic coil in the electromagnetic rod is energized to generate magnetism, which can magnetically adsorb the rust slag and iron debris in the first separation chamber to achieve the collection of rust slag and iron debris. However, there are some problems in its use. After the filtration is completed, the cooling oil of this device will return to the base of the nut cold heading machine. When the cooling oil is extracted from the base of the nut cold heading machine, a small amount of impurities will still enter the pipeline and spray to the upper end of the cold heading machine, which will affect the processing quality of the fastener; the above patent can prove the defects of the prior art.

[0005] Therefore, we have made improvements to this and proposed a forming device for producing fasteners for high-speed railways. Summary of the invention

[0061] The use process of the forming device for producing fasteners for high-speed railways provided by the present invention is as follows:

[0062] Working principle: The staff connects the driving wheel 2 with the driving device, and the driving wheel 2 rotates to drive the extension shaft 16 to rotate, so that the convex plate 10 rotates with the axis of the extension shaft 16, and the rotating convex plate 10 drives the middle shaft 12 to rotate.

[0064] Oil filtration: During stamping, the cooling oil is sprayed on the pressing plate 19 to cool and press the fasteners, and the metal debris generated during the pressing process is cleaned. The cooling oil passing through the pressing plate 19 falls on the auxiliary plate 506 and the support plate 507, passes through the filter hole 501 therein, and is filtered, and falls into the collection box 510 for collection. At this time, the magnet rod 606 is directly below the support plate 507.

The auxiliary plate 506 is driven by the connecting rod 13, and the toothed plate 508 below the auxiliary plate 506 continuously hits the protruding rod 509, which generates vibration, and cleans the iron debris attached to the filter hole 501. When the auxiliary plate 506 moves, its magnet rod 606 first contacts the filter membrane plate 603, and absorbs the iron debris attached to the filter membrane plate 603. With the movement of the auxiliary plate 506, it slowly moves upward on the surface of the filter membrane plate 603, so as to clean the filter membrane plate 603. After passing the arc plate 604, the auxiliary plate 506 flips and drives the magnet rod 606 to separate from the arc plate 604, and driven by the torsion spring frame 605, it continues to reset and continues to be perpendicular to the bottom of the auxiliary plate 506;

[0065] Debris collection: During the stamping process, the auxiliary plate 506 is pulled by the support rod 504, so that the auxiliary plate 506 flips over and contacts the support plate 507, and drives the magnet rod 606 to contact the bevel plate 601 on the surface of the auxiliary bevel plate 602. Driven by the auxiliary plate 506, the magnet rod 606 contacts and scrapes the bevel plate 601 to clean the iron debris adsorbed on the surface of the magnet rod 606. After the auxiliary plate 506 overlaps with the support plate 507, The torsion spring frame 605 drives the magnet rod 606 back to the original position, which is located below the support plate 507. The slide plate 15 drives the positioning plate 801 to move toward one end of the moving wheel 2, pulling the corrugated airbag 802. The gas enters the corrugated airbag 802 along the open pipe 805 and the curved pipe 807. The gas carries the iron debris in the slot mold 7 into the corrugated airbag 802, passes through the narrow open pipe 803, and enters the corrugated airbag 802 for collection.

[0066] Material discharge and export: During the return process, the slide plate 15 moves forward, the corrugated airbag 802 is compressed, the gas is discharged by the check valve 808, and the fixed plate 806 contacts the narrow open tube 803 to prevent the gas from being discharged from the narrow open tube 803 and carrying iron debris into the slot die 7, while the positioning plate 801 continues to move, driving the curved tube 807 connected to the fixed plate 806 to push the stamped workpiece out of the slot die 7. After the workpiece falls on the auxiliary plate 506, it is driven by the support rod 504, and the auxiliary plate 506 slides on the surface of the support plate 507. After the tail end of the toothed plate 508 below the auxiliary plate 506 contacts the protruding rod 509, the auxiliary plate 506 flips over to tilt the completed workpiece and export it.
