Description

Technical Field

[0001] The invention relates to the technical field of fasteners, in particular to the technical field of fastener wire grinding devices. Background Art

[0002] Fasteners are mechanical parts used for fastening connections. They are widely used in industries such as energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds and hydraulics. They are characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization and generalization.

[0003] Fasteners are usually made of fastener wire as raw material and processed through a series of processes such as pickling, stretching, heading and tailing. The purpose of the pickling process is to use an acid solution to remove the oxide scale and rust on the surface of steel (after welding and annealing, the surface of the fastener wire will inevitably produce oxidation and affect the product quality). However, the existing pickling processes and pickling devices, such as a fastener raw material pickling process with publication number CN107557798A, a fastener forming process with announcement number CN112108837B, and a bolt wire pickling device with announcement number CN215560699U, often require a large amount of hydrochloric acid, which has a serious pollution problem (which restricts the development of the standard parts industry).

[0004] At present, there are devices on the market that use horizontal grinding wheels and longitudinal grinding wheels to grind wires respectively, such as a descaling device for metal wire surface treatment with announcement number CN211053390U. However, due to the small grinding coverage of such devices (there are grinding dead corners), the fastener wire cannot be fully descaled by only one round of grinding. In addition, during the grinding period, since the various grinding parts of the device are directly exposed to the outside, on the one hand, the dust concentration in the processing workshop is increased, affecting the health of the workers, and on the other hand, the generated metal dust cannot be collected and uniformly processed, resulting in a certain amount of waste.

[0030] Working process of the present invention: When in use, firstly, the fastener wire is passed through and continuously conveyed along the slit (the fastener wire can be manually pulled by a worker or electrically pulled by a pulling device), and then the belt driving mechanism 2 is used to circulate the belt surface, and the slit is rotated around the fastener wire by the seam driving mechanism 3, so that the grinding belt group 1 performs a rotary oxide grinding treatment on the fastener wire. For the belt driving mechanism 2, the belt driving motor 23 can drive the belt driving driven gear 25 to rotate through the belt driving active gear 24, so that the roller 21 is used to drive the grinding belt sleeved outside it to move cyclically. For the seam driving mechanism 3, the seam driving motor 32 can drive the seam driving driven gear 34 to rotate through the seam driving active gear 33, so that the slit rotates together with the rotating drum 31.

[0031] During the grinding process, the exhaust fan 91 is started and the air mixed with metal dust inside the isolation cover 94 is successively sent into the casing 7 along the branch air duct 93 and the air collecting duct 92 and blown toward the mesh bag 5. At this time, the metal dust will be trapped by the mesh bag 5, and the filtered air will penetrate the mesh bag 5 and leave the casing 7 through the air outlet 74. During this period, the bag shaking assembly 8 will continue to shake the mesh bag 5, so that the metal dust adhering to the inner wall of the upper section of the mesh bag 5 passes through the convergence part and falls into the bottom of the bag. Specifically, the shaking The bag motor 81 can drive the bag shaking rod 82 to rotate, and the bending portion 821 will pull the net bag 5 up and down through the wires 83 during the rotation of the bag shaking rod 82 to complete the shaking operation. After a period of use, the shell cover 72 can be opened, and each hook 84 can be disengaged from the corresponding pull ring 85 respectively, and each set of bolts and nuts can be removed, and then the movable ring 4 and the net bag 5 can be taken out from the casing 7 to clean out the collected metal dust. In addition, the operating door 7 can be opened to squeeze the net bag 5 upward, thereby assisting the net bag 5 to pass through the annular retracted portion 711.

[0032] Before use, the width of the slit can also be adjusted according to the wire diameter of the fastener wire. Specifically, first remove the isolation cover 94, insert the end of the column 27 with the positioning screw hole into the base 26 along the socket and control the insertion depth, then pass the screw of the bolt through the long slot 261 and screw it into the positioning screw hole until the base 26 and the column 27 are fixed together.
