The prior method for removing rust on the surface of a steel wire is generally an acid pickling rust removal method. The principle is that the chemical reaction between acid in the acid washing solution and metal oxide is utilized to dissolve the metal oxide, so as to remove the rust and dirt on the surface of the steel. However, after the steel wire is washed by acid and derusted, a large amount of clear water is required for cleaning and passivation treatment, and a large amount of waste water, waste acid and acid mist formed by the steel wire cause environmental pollution. If not properly treated, the metal surface can be over-etched to form pits. Under the severe situation of haze, river pollution and land pollution on ten surfaces in various places and the environmental protection pressure of public opinion, the national strong pollution control has more and more strong decisions.

As shown in fig. 2 to 3, a discharging machine 1 is provided. The discharging machine 1 comprises a discharging rack 11, wherein a framework of the discharging rack 11 is constructed by I-shaped steel, a desktop part for installation is rectangular, at least one installation part 111 is arranged on the desktop part, and the installation parts 111 are respectively formed by matching an upper steel plate, a lower steel plate and the I-shaped steel; the upper steel plate and the lower steel plate are respectively a first steel plate 112 and a second steel plate 113; the first steel plate 112 and the second steel plate 113 are fixedly connected through an I-shaped steel 114, and two ends of the first steel plate 112 are erected on the top end of the emptying frame 11, namely a table top.

A steel wire separation assembly 12, a tensioning traction mechanism 13 and a # -shaped wheel set mechanism 14 are respectively arranged on the discharging rack 11, and the steel wire enters the rust removing device 2 after passing through the # -shaped wheel set mechanism 14, the tensioning traction mechanism 13 and the steel wire separation assembly 12 in sequence.

As shown in fig. 5 to 7, the transverse-shaped wheel assembly mechanism 14 is disposed at the front end of the small guide wheel assembly 136, the steel wire enters the transverse-shaped wheel assembly mechanism 14 and then is introduced into the small guide wheel assembly 136, and the transverse-shaped wheel assembly mechanism 14 includes a mounting plate 141 fixed on the emptying frame 11, a fixing plate 143 oppositely disposed on the mounting plate 141, and side plates 142 respectively fixed on both sides of the mounting plate 141 and the fixing plate 143. The side plates 142 are located on two sides of the steel wire outgoing direction, and the fixing plate 143 is parallel to the mounting plate 141.

A group of first rollers 144 are respectively arranged at the front end and the rear end of the # -shaped wheel set mechanism 14 along the wire routing direction, and two ends of each first roller 144 are respectively rotatably connected with the mounting plate 141 and the fixing plate 143; a group of second rollers 145 is arranged between the two side plates 142, the second rollers 145 are rotatably connected with the side plates 142, the axis of the second rollers 145 is perpendicular to the axis of the first rollers 144, namely, the first rollers 144 are vertically arranged, and the second rollers 145 are transversely arranged; the first rollers 144 of the same group are located on the same side of the second rollers 145, that is, along the wire routing direction, and a group of first rollers 144 is respectively disposed on the front and rear sides of the side plate 142. The spacing between the two first rollers 144 of the same set substantially corresponds to the diameter of the wire, and the spacing between the two second rollers 145 also substantially corresponds to the diameter of the wire. The basic consistency means that the distance can be equal to the diameter of the steel wire and can be slightly larger than the diameter of the steel wire, more steel wires can pass through the space, the steel wires are limited vertically and horizontally, and random jumping of the steel wires is avoided.

Two second rollers 145 are provided between the two sets of first rollers 144, the two second rollers 145 and the two sets of first rollers 144 cooperating to define apertures through which the steel wire passes.

All the first rollers 144 and the second rollers 145 are movable and rotate under a force, that is, the friction force generated when the steel wire passes through drives the steel wire to rotate; the # -shaped wheel set mechanism 14 is used for limiting the steel wire up and down, left and right, preventing the steel wire from coming off and scratching the subsequent tensioning traction mechanism 13. The above is the most preferred embodiment, and in addition, there are two less preferred embodiments. The difference between the sub-optimal embodiment 1 and the optimal embodiment is as follows: there are a pair of vertically disposed first rollers 144 and two pairs of horizontally disposed second rollers 145, the two pairs of second rollers 145 being located on opposite sides of the first rollers 144, respectively.

The shape of the groove of the first oblique guide wheel 131 for guiding the steel wire is oblique, so that the steel wire can be more smoothly guided into the steel wire separation assembly 12, and the steel wire can be twisted in the process of entering the steel wire separation assembly 12, so that rust on the surface of the steel wire can be primarily treated.

The first tension pulley 132, the second tension pulley 133 and the first oblique guide pulley 131 are mounted on the second steel plate 113 below the mounting part 111 of the emptying frame 11, and the first steel plate 112 above is mounted with two power mechanisms respectively matched with the first tension pulley 132 and the second tension pulley 133. The power mechanism comprises a motor 134 and a speed reducer 135, and the first tension pulley 132 and the second tension pulley 133 rotate under the control of the respective motor 134 and the speed reducer 135.

The first oblique guide wheel 131, the first tension wheel 132 and the second tension wheel 133 are arranged in a triangular shape.

The wire 2333 passes through the cross wheel set mechanism 14, then passes through the small guide wheel set 13, then passes through the second tension wheel 133 and the first tension wheel 132, and finally is led into the wire separating assembly 12 through the first oblique guide wheel 131. Since the first tension pulley 132 and the second tension pulley 133 are located at the middle of the tensioning traction mechanism 13, the force required by the power mechanism to drive the first tension pulley 132 and the second tension pulley 133 to advance the wire is small.

To facilitate the rotation of the adjusting screw 1369, the end of the screw 1369 exposed from the nut 1370 is connected to an adjusting knob 1367. In summary, the screw mechanism 1366 can adjust the position of the second small guide wheel 1363, so as to adjust the tension of the steel wire 2333, and the steel wire passes through the tension, so that the steel wire is deformed to provide traction for the steel wire, and the steel wire enters the steel wire separating assembly 12 and the derusting mechanism 2 to provide inlet tension.

The steel wire separation assembly 12 is installed on one side of the discharging rack 11 and comprises two separation rollers 121 which are arranged in parallel up and down, and the two separation rollers 121 are very close to each other or even attached to each other. As shown in fig. 4, the two separation rollers 121 are press-fitted by using a special bearing housing in cooperation with a standard bearing.

The steel wire is twisted by a certain angle when the first steel wire deruster is used. The first steel wire derusting machine comprises a derusting rack 21, two steel wire twisting mechanisms 22 and two steel wire derusting mechanisms 23, wherein the two steel wire twisting mechanisms 22 are respectively arranged at a steel wire inlet and a steel wire outlet of the derusting rack 21, and the steel wire derusting mechanism 23 is arranged between the two steel wire twisting mechanisms 22 on the derusting rack 21.

As shown in fig. 8 to 13, the rust removing frame 21 includes a base 211, and the base 211 is rectangular. Two support columns 212 are provided on each of the left and right sides of the base 211, for a total of four support columns 212. The support posts 212 are arranged in a rectangular shape, and a top cover 213 is attached to the top ends of the four support posts 212. A vertical shaft sleeve 214 is arranged in the middle of two sides of the top cover 213, and a lifting motor 215, a corner device 201, a rotating shaft 217 and a derusting lifting mechanism 202 are further mounted on the top cover 213. Wherein the corner device 201 is arranged at the center of the top cover 213, and the lifting motor 215 is arranged right above the corner device 201 through the mounting bracket 203. The number of the rust removing lifting mechanisms 202 is two, and the two rust removing lifting mechanisms 202 are respectively positioned on two sides of the top cover 213.

As shown in fig. 8 to 14, the wire twisting mechanism 22 includes two conical deflecting rollers 221, and the two conical deflecting rollers 221 are installed to face each other. Among them, the steering roller 221 includes a steering roller shaft 2211, a plurality of steering bearings 2215 are installed on the steering roller shaft 2211, and sealing caps 2217 are installed at both end surfaces of the steering bearings 2215 for preventing dust from entering the inside of the steering bearings 2215. A round nut 2216 is provided at one end of the steering roller shaft 2211, and the steering bearing 2215 is pressed by tightening the round nut 2216, and the inner ring of the steering bearing 2215 is fixed. Each steering bearing 2215 is rotatably connected with a steering wheel 2212, and the diameter of each steering wheel 2212 increases progressively from one end of the steering roller 221 to the other end in an equal difference mode. Bearing support seats 2214 are provided at both ends of the steering roller shaft 2211. Each of the steering wheels 2212 can rotate independently about the steering bearing 2215. Through setting up steering bearing 2215 can make steering wheel 2212 rotate more nimble, effectively reduce frictional resistance, prevent that steering wheel 2212 from taking place wearing and tearing with steering roller axle 2211. In the steering wheel 2212, a constricted portion 2217 is formed by narrowing in the axial direction near the wheel body periphery of the steering wheel 2212, guide grooves 2213 are formed in the side wall of the constricted portion, and the depth of each guide groove 2213 is uniform.

The turning rolls 221 are fixed to the lower end of the upper beam 219 and the upper end of the lower beam 218, respectively, by bearing supports 2214. At least one of the upper beam 219 and the lower beam 218 may be vertically lifted along the pillar 212, and may be fixed after being lifted. In this embodiment, my party prefers the upper beam 218 to move. The concrete structure is as follows: the four pillars 212 are provided at the same height with slide grooves 222, and both ends of the upper beam 219 are installed in the slide grooves 222 and can move up and down along the slide grooves 222.

The second reduction motor 224 drives the synchronous rotation link 225 to rotate, so as to drive the two second worm gears 2231 to rotate synchronously, and the second lifting rod 2232 moves synchronously in the vertical direction along with the synchronous rotation link, so as to drive the upper cross beam 219 to move in the vertical direction along the sliding slot 222, and the upper cross beam 219 is fixed at a certain position after the second reduction motor 224 stops driving. In order to keep the wire in a more stable state, it is preferable that the upper beam 219 and the lower beam 218 are also installed between the two columns 212 located at the wire outlet, and a second reduction motor 224, a synchronous rotation link 225, and a beam elevating mechanism 223 are also installed.

As shown in fig. 15 to 19, the wire rust removing mechanism 23 includes an oblique beam 231, the lower end surface of the oblique beam 231 is an inclined surface, the other end surfaces are all flat surfaces, and the inclination angle of the lower end surface is consistent with the inclination angle and direction of the inclined surface formed between the wires.

First slide rails 2313 are respectively arranged on two sides of the lower end surface of the oblique beam 231, and at least one first slide block 2314 is mounted on each first slide rail 2313. The lower end of the first slider 2314 is connected with a phosphorus breaking roller seat 232, that is, two sides of the upper end surface of the phosphorus breaking roller seat 232 are respectively fixed at the lower end of the first slider 2314. A first speed reducing motor 2315 is installed on the narrower side of the oblique beam 231, and the first speed reducing motor 2315 is used for driving the phosphorus breaking roller seat 232 to move back and forth along the first slide rail 2313. The whole phosphorus breaking roller seat 232 is parallel to the lower end face of the oblique beam 231, the higher side of the phosphorus breaking roller seat 232 extends downwards to form an elbow 2321, the lower end of the elbow 2321 is provided with a first phosphorus breaking roller bearing seat 235, the outer side of the first phosphorus breaking roller bearing seat 235 is provided with a third speed reducing motor 239, and the third speed reducing motor 239 is used for driving a bearing of the first phosphorus breaking roller bearing seat 235 to rotate. A bearing seat base 237 is arranged at the lower end of the phosphorus breaking roller seat 232, and one end of the bearing seat base 237, which is positioned at the outer side, is rotatably connected with the phosphorus breaking roller seat 232. A first oil cylinder 238 is further installed inside the oblique beam 231, and the lower end of the oil rod of the first oil cylinder 238 is connected with one end of the bearing seat base 237 located at the inner side. Driven by the first oil cylinder 238, the bearing seat base 237 rotates around the rotating connection point of the bearing seat base and the phosphorus breaking roller seat 232. A second slide rail 2371 is arranged at the lower end of the bearing seat base 237, a second slide block 2372 is mounted on the second slide rail 2371, and the lower end of the second slide block 2372 is fixed with the upper end of the second phosphorus crushing roller bearing seat 236.

In a working state, two ends of the phosphorus crushing roller 233 are respectively arranged in the first phosphorus crushing roller bearing seat 235 and the second phosphorus crushing roller bearing seat 236.

Since the axial movement of the bearing seat base 237 and the first phosphorus crushing roller bearing seat 235 is mainly relied on during the roller loading action, the teeth of the outer gear 2331 are difficult to directly align with the teeth gap of the inner gear 2351, and in order to solve the problem, the present embodiment provides the following solution:

as shown in fig. 20, an elastic auxiliary mechanism is arranged on one opposite side of the first phosphorus breaking roller bearing seat 235 and the second phosphorus breaking roller bearing seat 236, the elastic auxiliary mechanism comprises a circular mounting base 2352, the mounting base 2352 is rotatably arranged on the first phosphorus breaking roller bearing seat 235 and the second phosphorus breaking roller bearing seat 236, four screw rods 2353 are uniformly arranged on the end surface of the mounting base 2352, each screw rod is sleeved with a disc spring 2354, an internal gear 2351 penetrates through the four screw rods 2353, and the mounting base 2352 and the internal gear 2351 can synchronously rotate; one end of the disc spring 2354 contacts the mounting base 2352, and the other end of the disc spring 2354 contacts the wheel surface of the internal gear 2351; an adjusting nut 2355 and a washer 2357 are mounted on the other end of the screw 2353. An external gear 2331 is fixedly sleeved on each shaft head 2336 at two ends of the phosphorus breaking roller 233, and the internal gear 2351 and the external gear 2331 are meshed with each other to complete the installation of the phosphorus breaking roller 233. The internal gear 2351 is inserted into the four screws 2353, and has a rear end surface 23514 abutting against the disc spring 2354 and a front end surface 23515 abutting against the washer 2357. A gear shaft 2356 is internally meshed and sleeved in the internal gear 2351, the exposed end 23562 of the gear shaft 2356 is provided with a cavity 23561 for the spindle head 2336 to be inserted into, and the gear shaft 2356 is always meshed with the internal gear 2351; as shown in fig. 20, the exposed end 23562 of the gear shaft 2356 is retracted inwardly relative to the front end surface 23515 of the inner gear 2351 to leave a void 23563 to facilitate entry of the outer gear 2331.

As shown in fig. 20, gear teeth are circumferentially distributed on the inner ring of internal gear 2351, the gear teeth of internal gear 2351 include two types, long teeth 23511 and short teeth 23512, the long teeth 23511 and the short teeth 23512 are circumferentially staggered, the short teeth 23512 are axially retracted into the inner ring from the front end face 23515 of internal gear 2351 to leave a pre-installation gap 23513, that is, a larger pre-installation gap 23513 is left between two adjacent long teeth 23511, and a smaller gap is formed between two adjacent long teeth 23511 and short teeth 23512.

As shown in fig. 21, the diameter of the outer gear 2331 is equal to the diameter of the gear shaft 2356; the outer gear 2331 is a comb-tooth gear, and sparse teeth 23311 are circumferentially distributed on the periphery of the outer gear, namely the number of the teeth 23311 is one half or one quarter of the sum of the number of the long teeth and the short teeth of the inner gear 2351; preferably: the sum of the number of long teeth 23511 and short teeth 23512 on the inner gear is equal to twice the number of teeth 23311 of the outer gear 2331, e.g., the number of long and short teeth of the inner gear totals 44, while the number of teeth 23311 of the outer gear is 22.

The gear shaft is sleeved in the inner gear in an engaged manner, the gear shaft and the inner gear 2351 are fixed in the circumferential direction, the inner gear 2351 can move in the axial direction, and in the process of installing the phosphorus breaking roller, shaft heads 2336 at two ends of the phosphorus breaking roller firstly enter a cavity 23561 of the gear shaft 2356; next, as shown in fig. 20, the outer gear 2331 at both ends of the phosphorus breaking roller is close to the front end surface 23515 of the inner gear 2351, since the phosphorus breaking roller is axially limited or is not moved in the axial direction, the outer gear 2331 is not moved, the gear shaft 2356 and the inner gear 2351 are continuously moved, and the inner gear 2351 is reversely pressed by the outer gear 2331, the disc spring 2354 is compressed to generate elastic force, and at the same time, the output end of the third speed reducing motor 239 drives the gear shaft on the first phosphorus breaking roller bearing seat 235 to rotate, when the preassembly gap 23513 is aligned with the tooth 23311, the inner gear 2351 moves back under the action of the elastic force, the outer gear 2331 firstly enters into the space 23563, and at the same time, the tooth 23311 of the outer gear enters into the large preassembly gap 23513 formed between the long tooth 23511 and the short tooth 23512, for example, the tooth 23311 abuts against the short tooth 23512 of the inner gear 2351, and the disc spring 2351 presses against the inner gear 235, at the moment, the gear shaft 2356 continues to rotate, when the teeth 23311 are aligned with the small gap between the long teeth 23511 and the short teeth 23512, the disc spring 2354 releases the elastic force again to push the inner gear 2351 back towards the phosphorus breaking roller, finally, the teeth 23311 enter the small gap between the long teeth 23511 and the short teeth 23512, the inner gear 2351 and the outer gear 2331 complete sleeving and meshing, power connection between the two is realized, and the phosphorus breaking roller 233 rotates along with the inner gear 2351 and the outer gear 2331. The design of the comb teeth of the outer gear is convenient for being meshed with the inner gear.

As shown in fig. 22 to 23, the phosphorus breaking roller 233 includes a roller core 2337, a winding band 2332 is wound around the surface of the roller core 2337 from one end to the other end, and both ends of the winding band 2332 are fixed after the winding band 2332 completely covers the surface of the roller core 2337. The coiled band 2332 has a structure with a wide bottom and a narrow opening, and includes a bottom plate 23321 and side panels 23322 at both sides of the bottom plate 23321. The side panels 23322 are tapered inward from bottom to top, with the distance between the two side panels being about one-half the distance between the bottom of the two side panels at the top. A wire 2335 is wound on the bottom plate 23321 of the winding band 2332, and a grinding roll 2334 is uniformly wound on the wire 2335, the grinding roll 2334 being made of nylon wire. The center of the grinding roller 2334 is folded back around the wire 2335 to be adjacent to each other and then extended from both ends of the upper end opening of the coiled band 2332. The sum of the wire diameter and the double grind bar 2334 diameter is less than the width of the bottom plate 23321 but greater than the spacing of the upper ends of the side gussets 23322, and the double grind bar 2334 diameter is substantially the same as the spacing of the upper ends of the side gussets 23322. (by substantially uniform herein is meant that twice the diameter of the grinding rods 2334 are spaced the same distance from the upper end of the side gusset 23322 or that twice the diameter of the grinding rods 2334 are spaced slightly less than the upper end of the side gusset 23322). The grinding bar 2334 is planted in the coiled band 2332 by a wire 2335.

By adopting the grinding roller 2334 to be planted on the coiling belt 2332, only the grinding roller needs to be coiled on the surface of the phosphorus breaking roller, and the two ends of the grinding roller are fixed, so that the grinding roller is very convenient to disassemble and assemble, and the defect of difficult assembly and disassembly caused by the traditional spot welding connection is avoided.

The first steel wire derusting machines are of two types, the structures are completely the same, and the difference is that one type of derusting machine frame 21 is higher, the steel wire is positioned below the phosphorus breaking roller in an inclined manner and is parallel to the roller surface of the phosphorus breaking roller, and the phosphorus breaking roller derusts the surface above the steel wire in the inclined manner; the other derusting machine frame 21 is lower, the steel wire is positioned above the phosphorus breaking roller in an inclined mode and is parallel to the surface of the phosphorus breaking roller, and the phosphorus breaking roller derusts the surface below the steel wire in the inclined mode.

The second steel wire deruster is conventional in structure, and the phosphorus breaking roller is horizontally arranged to derust the steel wires. The second steel wire derusters are also of two types, and the structures of the second steel wire derusters are identical. The difference also lies in the size of the derusting stand. One of the two methods is to remove rust by contacting the phosphorus breaking roller with the lower surface of the steel wire, and the other method is to remove rust by contacting the phosphorus breaking roller with the upper surface of the steel wire.

Fig. 24 is a schematic diagram showing a conventional method for removing rust from the surface of a steel wire. The general rust removing mechanism's phosphorus-breaking roller 233 only brushes the upper and lower surfaces of the steel wire 2333, but because of the circular structure of the steel wire cross-section, the closer to the left and right sides of the steel wire 2333, the smaller the pressure of the grinding roller 2334 on the phosphorus-breaking roller 233 to the steel wire 2333, and the smaller the friction force, the more the steel wire 2333 has, the cause that there are a rust removing blind area a and a rust removing blind area b in the area of about 5 ° each on both sides of the diameter parallel to the central axis of the phosphorus-breaking roller 233.

In order to solve the above problem, after a plurality of steel wires 2333 exit through the wire separating assembly 12 of the discharging machine, the plurality of steel wires 2333 are arranged side by side on a horizontal plane, and then the steel wires enter the wire twisting mechanism 22, so that the steel wires 2333 are arranged side by side on an inclined plane, as can also be seen in fig. 11 and 12; fig. 25 is a schematic view showing the twisting of the wire after passing through the wire twisting mechanism 22 of the first wire deruster. After the steel wires pass through the steel wire twisting mechanism 22, a plane formed by a plurality of steel wires side by side is integrally twisted for a certain angle, and the steel wire 2333 is also twisted for a certain angle in the circumferential direction under the action of the integral torsion force of the plane changed from a horizontal plane to an inclined plane, wherein the angle is about 4-6 degrees; the rust removing blind area a and the rust removing blind area b which cannot be brushed by the original flat brush are respectively twisted to the positions of a1 and b 1. As shown in the upper drawing of fig. 26, in the first wire derusting machine, in order to adapt to the inclined surface formed by a plurality of steel wires, the phosphorus-breaking roller 233 is also arranged obliquely, the phosphorus-breaking roller 233 removes the rust on the surface obliquely above the steel wires, and the original rust-removing dead zone a, namely the twisted a1, can be brushed clean by the phosphorus-breaking roller 233. As shown in the lower drawing of fig. 26, in the second first wire derusting machine, the phosphorus-breaking roller 233 removes rust on the surface of the wire obliquely below, and the original rust-removing blind area b, i.e., the twisted b1, can be brushed clean by the phosphorus-breaking roller 233. However, for the same reason, in fig. 26, the circle center connecting line 23330 of the plurality of steel wires 2333 is parallel to the central axis of the phosphorus crushing roller 233, and the positions of the two ends of the diameter of the steel wire 2333 through which the circle center connecting line 23330 passes form the rust removing dead zone c and the rust removing dead zone d.

The steel wire 2333 enters a second steel wire derusting machine after being derusted by the first steel wire derusting machine, the second steel wire derusting machine is provided with two guide rollers (not shown) which are arranged in parallel up and down, and the structure of the guide rollers is similar to that of the separation roller 121 of the steel wire separation assembly 12 in the feeding machine 1; the guide rollers are horizontally arranged, grooves are formed in the guide rollers along the circumferential direction and are arranged at intervals along the axial direction of the guide rollers, and after the two guide rollers are arranged in parallel, an upper adjacent groove and a lower adjacent groove form a guide roller way for a steel wire to pass through; the inclined plane formed by a plurality of steel wires becomes a horizontal plane after passing through the guide roller, similarly, as shown in fig. 27, the steel wires are twisted along the arrow direction, and the areas corresponding to the positions a1 and b1 where the steel wires are brushed return to the positions of the rust removing blind areas a and b at the left side and the right side of the steel wires where the circle center connecting line 23330 passes through; while the rust removing blind areas c and d which are not brushed in the first steel wire rust remover rotate to the positions c1 and d1 which can be brushed; through the complementary fit of the first and second wire derusters and the self-torsion of the steel wire, the steel wire 2333 is completely derusted without dead angles in the circumferential direction.

The derusting device 2 designed by the applicant has the function of automatically changing the roll, and the roll changing process is as follows:

step one, the roller changing trolley is pushed into the position right below the steel wire derusting mechanism 23 from the gap between the two support columns 212 on the side surface of the first steel wire derusting machine.

Step two, the lifting motor 215 is started to drive the corner device 201 to operate, so that the two rotating shafts 217 on the two sides rotate synchronously, the rotating shafts 217 drive the first worm gears 204 on the two sides to rotate synchronously, finally, the two first lifting rods 216 are driven to descend synchronously, and the oblique beam 231 descends to a specified position along with the two first lifting rods; in this process, the guide shaft 2311 moves downward within the sleeve 214, serving to stabilize the operation.

And step three, the second oil cylinder 2373 is started, the second sliding block 2372 is pulled to move outwards along the second sliding rail 2371, so that the phosphorus crushing roller 233 is separated from the first phosphorus crushing roller bearing seat 235, and at the moment, the first oil cylinder 238 is started to push the second phosphorus crushing roller bearing seat 236 to rotate to the horizontal position along the rotating connection point.

Step four: the clamp on the trolley clamps the phosphorus crushing roller 233, the trolley is withdrawn, and the phosphorus crushing roller 233 is separated from the second phosphorus crushing roller bearing seat 236.

And step five, taking down the replaced phosphorus crushing roller 233, replacing with a new phosphorus crushing roller 233, and clamping by using a clamp.

Step six: the trolley is pushed into the position right below the wire derusting mechanism 23 from the gap between the two support columns 212 on the lateral surface of the first wire derusting machine, one end of the phosphorus breaking roller 233 is arranged in the second phosphorus breaking roller bearing seat 236, and the clamp on the trolley is loosened.

Step seven: the first oil cylinder 238 is started to pull the second phosphorus breaking roller bearing seat 236 upwards to rotate along the rotating connection point to be parallel to the lower end face of the oblique beam 231, at the moment, the second oil cylinder 2373 is started to push the second sliding block 2372 to move inwards along the second sliding rail 2371, so that the other end of the phosphorus breaking roller 233 is mounted on the first phosphorus breaking roller bearing seat 235.

Step eight: the lifting motor 215 is started to drive the corner device 201 to operate, so that the two rotating shafts 217 on the two sides rotate synchronously, the rotating shafts 217 drive the first worm gears 204 on the two sides to rotate synchronously, finally, the two first lifting rods 216 are driven to ascend synchronously, and the oblique beam 231 ascends to a specified position along with the two first lifting rods.

In the steps, the step two and the step three can be interchanged, and the step seven and the step eight can be interchanged.

The first steel wire derusting machine comprises the following derusting processes:

the steel wire gets into the first steel wire deruster on the assembly line traffic direction, the steel wire passes through turn roll 211 earlier, under the drive of second gear motor 224, crossbeam elevating system 223 promotes entablature 219 and descends downwards, thereby the drive is installed and is gone down to turn roll 221 on it, restrict the steel wire in the guide slot 2213 of two upper and lower turn rolls 221, play the effect that prevents the steel wire and jump, because the structural feature of turn roll 221, the steel wire receives stress effect and has twisted about 5 angles at this in-process. The vertical position of the phosphorus breaking roller 233 is adjusted by the lifting motor 215, and the vertical position and the horizontal position of the phosphorus breaking roller 233 are adjusted by the first speed reducing motor 2315, so that the rust removal is performed on the inclined upper surface of the steel wire in the advancing process of the steel wire. And then the steel wire is subjected to further rust removal treatment on the inclined upper surface of the steel wire through a plurality of first steel wire rust removal machines, so that the rust removal effect is ensured. And then the steel wire enters a second first steel wire derusting machine, and the second first steel wire derusting machine derusts the oblique lower part of the steel wire. The second steel wire deruster adopts a flat brush mode to derust the surface of the steel wire, and because the original derusting dead zone a and the original derusting dead zone b are derusted completely in the first steel wire deruster, the surface of the steel wire is completely cleaned.

After the steel wire subjected to the rust removal treatment by the rust removal device 2 is treated by the shot blasting machine 7, the internal stress can be well eliminated, and the surface rust can be further cleaned.
