Description

Technical Field

[0001] The invention relates to the technical field of lead scraping on the surface of a steel strip, in particular to a lead scraping mechanism for a steel strip after heat treatment and lead dipping. Background Art

[0002] The main purpose of lead dipping after heat treatment of steel strip is to improve its own toughness, elasticity, hardness and wear resistance. After being dipped in lead liquid, the surface of the steel strip has abnormal protrusions or burrs, so a specific lead scraping mechanism is needed to level the lead layer on the surface of the steel strip.

[0003] After the steel strip is heat treated and put into the lead liquid to extract the coating, when the semi-solid lead layer is directly scraped flat by a scraper or other equipment, the compressed lead layer is prone to wrinkles due to excessive pressure. In severe cases, the lead layer on the surface of the steel strip may break. Therefore, it is extremely important to scrape flat the solidified lead layer. However, the existing method of scraping off the solidified lead still has certain disadvantages. Since the steel strip is long and the thickness of steel strips of different specifications is different, when the thinner steel strip is processed by a scraper or other equipment, resonance will occur in the exposed part. In severe cases, it will cause wear on the compressed part of the steel strip, and if the compressed area of ​​the lead layer is too small, it will also be damaged due to the continuous increase in pressure.

It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0053] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0054] The following describes a lead scraping mechanism after lead dipping in the heat treatment of a steel strip provided by some embodiments of the present invention with reference to the accompanying drawings.

[0055] Embodiment 1:

[0056] Combined with Figures 1 to 9 As shown in the figure, a lead scraping mechanism after lead dipping in the heat treatment of a steel strip provided by the present invention includes a strip surface assisting pressure mechanism 200 arranged outside the steel strip 100, a strip width expansion mechanism 300 arranged on the strip surface assisting pressure mechanism 200, a driving mechanism 400 arranged on the strip width expansion mechanism 300, an amplitude vibration mechanism 500 arranged inside the strip surface assisting pressure mechanism 200, and an auxiliary flattening mechanism 600 arranged inside the strip width expansion mechanism 300. The auxiliary flattening mechanism 600 is located directly above the steel strip 100. The strip surface assisting pressure mechanism 200 is used to provide non-destructive bearing for steel strips 100 with different thicknesses, and at the same time cooperate with the amplitude vibration mechanism 500 and the auxiliary flattening mechanism 600 to flatten the passing steel strip 100. The strip width expansion mechanism 300 is used to provide an extended support platform for the auxiliary flattening mechanism 600, and the driving mechanism 400 is used to provide kinetic energy for the vibration of the amplitude vibration mechanism 500.

[0057] The strip surface assisting pressure mechanism 200 includes two load-bearing beam rails 210 and four stability-enhancing slide rails 240. A bearing plate 220 is arranged on the top of the two load-bearing beam rails 210. A limiting vertical plate 230 is arranged outside the stability-enhancing slide rails 240 and the load-bearing beam rails 210. A plug 250 is arranged at the outer end of the stability-enhancing slide rail 240. A limiting rod 260 is arranged inside the plug 250, and the other end of the limiting rod 260 is adaptively penetrated into the inside of the stability-enhancing slide rail 240. A spring 270 is arranged outside the limiting rod 260;

[0058] The inside of the stability - enhancing slide rail 240 is provided with a chute, and a convex plate is arranged at the bottom of the outer end of the stability - enhancing slide rail 240.

[0059] The bandwidth expansion mechanism 300 includes a main push rod 360 arranged inside the limit vertical plate 230. A second traction member 370 is arranged at the outer end of the main push rod 360. A chuck 380 is arranged at the bottom end of the second traction member 370. A T - shaped slider is arranged at the top of the chuck 380, and the T - shaped slider is adapted to penetrate through the chute of the stability - enhancing slide rail 240. Column heads are arranged on both sides of the chuck 380;

[0060] Two symmetrically distributed slide plates are arranged outside the main push rod 360, and the slide plates are adapted to penetrate through the inside of the limit vertical plate 230;

[0061] Through holes are arranged at both ends of the main push rod 360 and inside the chuck 380, and bearings 390 are arranged inside the through holes.

[0062] The driving mechanism 400 includes a chassis 410 arranged on the top of the top - support plate 310, a motor 420 arranged inside the chassis 410, a runner 430 installed at the outer end of the transmission shaft inside the motor 420, a traction plate 440 movably installed on the runner 430, and a striker 450 movably connected to the other end of the traction plate 440;

[0063] The amplitude - vibration mechanism 500 includes a frequency - vibration plate 530, a plurality of vertical rods 510 arranged inside the frequency - vibration plate 530, and compression springs 520 arranged outside the vertical rods 510;

[0064] The vertical rods 510 are made of stainless steel material.

[0065] The auxiliary flattening mechanism 600 includes two pressurizing rollers 620 movably installed inside two main push rods 360, two driving rollers 610 arranged inside four chucks 380, and a chain - belt plate 630 drivingly connected to the outside of the driving rollers 610 and the pressurizing rollers 620;

[0066] The frequency - vibration plate 530 is located inside the chain - belt plate 630. The two pressurizing rollers 620 are arranged at both ends of the two main push rods 360;

[0067] The driving rollers 610 are arranged inside two adjacent chucks 380.

[0068] Since steel strips 100 with different thicknesses need to be immersed in lead solution after heat treatment until the steel strips 100 are plated in the lead solution. After the steel strips 100 are removed from the lead solution, an external cooling medium is used to cool the plated steel strips 100;

[0069] After the steel strip 100 passes over the top of the bearing plate 220, the chain belt plate 630 attached to the top of the steel strip 100 can provide limit protection for its stable lateral movement. When an external driving device drives one of the second gears 650, the two driving rollers 610 can rotate at the same speed in cooperation with the chain 660. At this time, the chain belt plate 630 can boost a large area of the top of the steel strip 100. At the same time, after the frequency vibration plate 530 arranged inside the chain belt plate 630 fits against the inside of the chain belt plate 630, the frequency vibration plate 530 that is highly impacted by the striker 450 can vibrate the part of the chain belt plate 630 that fits against the top of the steel strip 100. At this time, the rotating chain belt plate 630 can cooperate with the frequency vibration plate 530 to effectively flatten the lead layer on the surface of the steel strip 100;

[0070] When it is necessary to process steel strips 100 with different thicknesses, the hydraulic component 320 can be operated until the hydraulic sub-rod inside the hydraulic component 320 pushes the support plate 330 to rise and fall stably. Finally, multiple first traction components 350 and multiple second traction components 370 can provide equidistant boosting forces to the two pressurizing rollers 620 and the two driving rollers 610. At this time, the thinner steel strip 100 can avoid abnormal jitter during the flattening of the lead layer, thereby avoiding abnormal friction between the jittering steel strip 100 and the pressurizing assembly.

[0071] Embodiment 2:

[0072] Combined with Figures 2 to 6 As shown, on the basis of Embodiment 1, the belt surface boosting mechanism 200 further includes two sets of belt distance control components 280;

[0073] The belt distance control component 280 includes a second base 282 installed on the load-bearing beam rail 210, a first base 281 arranged on the stability-enhancing slide rail 240, and a distance control pad 283 arranged between the first base 281 and the second base 282;

[0074] Both the top and bottom ends of the distance control pad 283 are provided with inclined surfaces, and a plurality of vertically distributed vertical holes are opened inside the distance control pad 283, and combined bolts 284 are arranged in the vertical holes.

[0075] Preferably, steel strips 100 with different thicknesses are adjusted by four combined bolts 284 and four distance control pads 283. As the inclined surfaces at the top and bottom of the distance control pad 283 fit the end faces of the first base 281 and the second base 282, the combined bolts 284 can be effectively fixed finally. At this time, a constant gap can be maintained between the load-bearing beam rail 210 and the chain belt plate 630, thereby avoiding abnormal deformation of the steel strip 100 due to excessive compression during the flattening and lateral movement.

[0076] Two symmetrically distributed holes are opened at the inner end of the stability-enhancing slide rail 240, and the vertical rod 510 is adaptively penetrated into the holes;

[0077] The bottom end of the compression spring 520 is adaptively pressed against the top of the stability - enhancing slide rail 240.

[0078] Preferably, the stability - enhancing slide rail 240 is fixedly installed on the limiting vertical plate 230. The frequency - vibrating plate 530 supported by multiple compression springs 520 can be adaptively attached to the inner side of the chain - belt plate 630 in the initial state. As the striker 450 impacts the frequency - vibrating plate 530, the whole frequency - vibrating plate 530 can perform micro - vibrations in the middle of the four stability - enhancing slide rails 240, so as to ensure that the rotating chain - belt plate 630 can resonate with the steel belt 100 over a large area.

[0079] Embodiment 3:

[0080] Combined with Figure 4 and Figure 7 As shown, on the basis of Embodiment 1, the bandwidth expansion mechanism 300 further includes a top - supporting plate 310 installed on the top of the limiting vertical plate 230. A hydraulic component 320 is arranged in the middle of the top - supporting plate 310, and a supporting plate 330 is arranged on the hydraulic sub - rod in the hydraulic component 320;

[0081] The two ends of the supporting plate 330 are movably connected with a first traction member 350.

[0082] Preferably, four feet are installed at the four ends of the bottom of the top - supporting plate 310, and the four feet are fixedly installed at the top end of the limiting vertical plate 230 by bolts. At this time, the top - supporting plate 310 can provide an effective suspension support platform for the auxiliary flattening mechanism 600.

[0083] The other end of the first traction member 350 is movably installed at the outer end of the sliding plate;

[0084] One end of the hydraulic component 320 is provided with a sheath 340;

[0085] The striker 450 is adaptively penetrated into the inside of the sheath 340, and the bottom end of the striker 450 is adaptively pressed against the top of the frequency - vibrating plate 530;

[0086] A groove is formed on one side of the top - supporting plate 310, and the top end of the striker 450 is located in the groove.

[0087] Preferably, the chuck 380 is movably installed in the stability - enhancing slide rail 240, and the limiting rod 260 is adaptively penetrated into the horizontal hole inside the chuck 380. One end of the spring 270 is connected to the inner wall of the stability - enhancing slide rail 240, and the other end of the spring 270 is connected to the chuck 380.

[0088] Embodiment 4:

[0089] Combined with Figures 7 to 9 As shown, in the above - mentioned embodiment, the auxiliary flattening mechanism 600 further includes a first gear 640 and a second gear 650 arranged on the shaft rod at one end of the driving roller 610;

[0090] Two first gears 640 are drivingly connected to a chain 660.

[0091] Preferably, both the driving roller 610 and the boosting roller 620 are composed of a horizontal shaft and an I-shaped sleeve roller, and two bearings 390 are installed at both ends of the horizontal shaft;

[0092] The chain belt plate 630 is composed of a plurality of leaf plates and a plurality of inserting rods to form a transmission belt structure.

[0093] The working principle and usage process of the present invention: After the steel strip 100 is heated to the austenitizing temperature and is in a state between liquid and semi-solid, then the steel strip 100 in this state is delivered into the molten lead liquid. After the heated steel strip 100 is immersed in the lead solution, it is left standing for a period of time until a layer of lead is evenly provided on the surface of the steel strip. Then, a cooling medium is used to quickly cool down the lead-dipped steel strip. After the isothermal transformation of the steel strip, the steel strip can be delivered towards the tops of the two load-bearing beam rails 210 and the bearing plates 220. At this time, the sunken chain belt plate 630 is adapted to fit the top surface of the steel strip;

[0094] By using an external driving device to drive one of the second gears 650, the first gear 640 can obtain the effective transmission of the chain 660. With the two boosting rollers 620 tightly supporting the chain belt plate 630, the driven chain belt plate 630 can boost the steel strip 100 to move horizontally at a constant speed;

[0095] When the motor 420 starts and operates, the internal transmission shaft will start the runner 430 to rotate at a high speed. At this time, the traction plate 440 movably installed on the column deviating from the center of the runner 430 will drive the impact pin 450 to reciprocate up and down. Under the limiting and stabilizing action of the sheath 340, the impact pin 450 can exert an impact force on the frequency vibration plate 530. The frequency vibration plate 530 can exert vibration on the part of the chain belt plate 630 that fits the top surface of the steel strip 100 under the high-frequency impact. Under the action of the impact vibration, the frequency vibration plate 530 and the bearing plate 220 can vibrate and smooth the lead protrusions or burrs on the top and bottom surfaces of the steel strip 100;

[0096] When it is necessary to process steel strips 100 with different thicknesses, the hydraulic component 320 is operated until the hydraulic sub-rod in the hydraulic component 320 pushes the whole pallet 330 to descend. Finally, the pallet 330 will simultaneously push the four first traction members 350. The two main push rods 360 being pushed will simultaneously push the four second traction members 370. Finally, the two driving rollers 610 and the two boosting rollers 620 will be pressed down until the chain belt plate 630 increases the contact area with the steel strip. At this time, when the thinner steel strip 100 flattens the lead layer, abnormal shaking of the exposed part can be avoided, thereby reducing the problem of wear of the lead layer caused by the shaking of the steel strip. Furthermore, the lead layer on the surface of the steel strip can be flattened by a strong pressing method.

[0097] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
