step S1: feeding the steel pipe or wire into the feed port 12, and cutting the steel pipe or wire into a processing section material by the cutting assembly 20;
step S2: the processing section material falls under gravity and along the first inclined plate 411, and adheres to the rust-removing oil dropped from the plurality of oil dropping needle tubes 32 during the falling, and then falls into the transverse plate 412;
step S3: the machining section material entering the transverse plate 412 is magnetically attracted by the electromagnet 522, moves upwards obliquely along the inclined surface 534 and enters the guide groove 533, the restoring spring 524 and the guide spring 520 are compressed until the conductive sheet abuts against the end wall of the conductive table 526, the control oil cylinder 511 is started by sending an electric signal, the grinding shell 512 is driven to fall, meanwhile, the two mechanical clamps 514 are started, the two mechanical clamps 514 clamp the machining section material, and then the steel brush 513 is started, so that the steel brush 513 performs reciprocating linear motion along the length direction of the grinding shell 512 to grind the machining section material;
step S4: the post-grinding control cylinder 511 drives the grinding housing 512 to move upwards in a reverse direction, then the electromagnet 522 is turned off, the restoring spring 524 and the guiding spring 520 are restored, the machining section material obliquely falls down to the second inclined part 42, overturned down to the third inclined part 43 through the overturning gap 420, and then enters the cold heading assembly 60 through the blanking gap 430 to be forged and formed.
For example, in one embodiment: the steel tube or steel wire is fed into the feed port 12 and cut by the cutting assembly 20, so that the steel tube or steel wire is cut into a processing section material, and the steel tube or steel wire is inclined downwards around a cutting stress point until the steel tube or steel wire breaks to form the processing section material, falls into the first guide cambered surface 414 of the first inclined part 41, moves downwards along the first inclined plate 411, adheres rust removing oil when moving to the lower part of the lubricating assembly 30, and moves downwards along with the rust removing oil until moving to one end of the transverse plate 412.
When moving to one end of the transverse plate 412, the relay controller 521 will start the electromagnet 522, the processing section material continues to accelerate under the action of inertia and magnetism of the electromagnet 522, impact the filtering guide plate 525, so that the filtering guide plate 525 moves to one side of the relay controller 521, the restoring spring 524 and the guiding spring 520 compress until the conductive sheet abuts against the end wall of the conductive table 526, meanwhile, as the electromagnet 522 is positioned at the top of the light plate 523, the processing section material moves obliquely to the guiding groove 533 along the inclined surface 534 under the action of inertia and magnetism, so that the filtering guide plate 525 moves obliquely to one side of the relay controller 521, an acute angle is formed between the filtering guide plate 525 and the light plate 523, so that the compression amount of the upper parts of the restoring spring 524 and the guiding spring 520 is larger, and the inclination of the processing section material is also larger.
Meanwhile, since the conductive sheet abuts against the end wall of the conductive table 526, an electrical signal is sent to the control oil cylinder 511, so that the control oil cylinder 511 drives the polishing shell 512 to move downwards until the bottom surface of the polishing shell 512 abuts against the top surface of the transverse plate 412, the polishing shell 512 is sleeved on the filtering guide plate 525, and the two mechanical clamps 514 are started and clamped on two sides of the processing section material, so that the processing section material is fixed, and then the steel brush 513 is started, so that the steel brush 513 performs reciprocating linear motion along the length direction of the polishing shell 512 to polish the processing section material.
Because the magnetism that the electro-magnet 522 produced will make the just brush in the steel brush ware 513 will polish towards filtration guide board 525 one side slope for most rust cleaning oil that produces of polishing splashes and will strike and get into filtration guide board 525, the rust cleaning oil that splashes will mix a large amount of metal fragments owing to polishing in, wherein metal fragments will be filtered owing to second filter screen 531, and accumulate in filtration guide board 525 outside, and rust cleaning oil will get into the cavity of liquid collection frame 529, and get into out liquid hole 537 along drainage face 536, then get into back into oil storage tank 31 along the pipeline and carry out cyclic utilization, the purification and the rust cleaning treatment to the processing section material surface have been realized, waste liquid that will produce simultaneously is filtered and recycle, environmental protection and energy saving's purpose has been reached, and metal fragments and rust cleaning oil that produce during polishing can be separated and filtered by high-efficient, make purifying effect better.
For example, in one embodiment: because the steel brush 513 reciprocates in a straight line, a small portion of the splashed rust-removing oil will impact the first filter screen 515 backward, and because the first filter screen 515 filters, metal chips will be blocked outside the first filter screen 515, and the rust-removing oil will enter the first oil collecting cavity 518 and flow into the second through hole 510 along the first oil guiding surface 519, and then enter the cold heading assembly 60 along the pipeline, thereby providing lubrication for forging of the cold heading assembly 60, reducing friction and heat of the material, reducing deformation and damage of the material in the cold heading process, forming a rust-preventing oil film on the produced product in the cold heading process, and guaranteeing the service life of the produced product.
Meanwhile, the rust-proof oil splashed out from other parts in the rust removal process of the steel brush 513 flows to the inner wall of the polishing shell 512 and flows to the top surface of the transverse plate 412 along the inner wall of the polishing shell 512, then enters the first guide cambered surface 414, and is gathered with the rust-proof oil dropped by the plurality of oil dropping needle tubes 32 in the first inclined plate 411.
Because the end of the hanging brush 527 away from the torsion spring is made of magnetic materials, when the electromagnet 522 is attracted to one side of the electromagnet 522 in a rotating way around the torsion spring, when the magnetism of the electromagnet 522 disappears, the hanging brush 527 is restored to be parallel to the length direction of the filtering guide plate 525 under the action of the torsion spring, and splashed metal scraps are scraped away.
For example, in one embodiment: after finishing polishing of steel brush 513, relay controller 521 will de-energize electromagnet 522 for magnetism disappears, restoring spring 524 and guiding spring 520 resume, make the conducting strip no longer support in conducting bench 526, make two mechanical clamps 514 will open, control cylinder 511 will control polishing casing 512 to move up, simultaneously because restoring spring 524 and guiding spring 520 upper portion's compression volume is bigger, and guiding spring 520 sets up in the bight department of lightweight board 523 adjacent first through hole 413, make filtering guide plate 525 will move obliquely to the bight department adjacent first through groove 415, and present the upset trend, make the processing section material fall into second tilting portion 42 through first through groove 415, because filtering guide plate 525 will produce the upset trend to the processing section material adjacent first through groove 415 bight department oblique movement, and because processing section material one end is derusted through steel brush 513, and processing section material other end is because two mechanical clamps 514 centre gripping are not derusted, make processing section material derusted one end lighter, when falling into upset clearance 420, will take place the upset, make the blanking not derusted one end down to go into the cold-formed end and make the forging component 60 to get into the cold-formed by the forging component 60 and make the cold-formed end rust removal component, the cold-formed part is damaged. Meanwhile, one end of the processing section material subjected to rust removal and polishing is upwards subjected to pressurized forging, so that the consistency and stability of the surface quality of the processing section material in the cold heading process can be ensured.
