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 the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0025] The belt surface pressure assisting mechanism 200 includes two load-bearing beam rails 210 and four stabilizing slide rails 240. A pressure plate 220 is arranged on the top of the two load-bearing beam rails 210. A limiting vertical plate 230 is arranged outside the stabilizing slide rails 240 and the load-bearing beam rails 210. A plug 250 is arranged at the outer end of the stabilizing slide rail 240. A limiting rod 260 is arranged inside the plug 250. The other end of the limiting rod 260 is adapted to penetrate the inside of the stabilizing slide rail 240. A spring 270 is arranged outside the limiting rod 260. A slide groove is formed inside the stabilizing slide rail 240 , and a convex plate is disposed at the bottom of the outer end of the stabilizing slide rail 240 .

[0026] The bandwidth expansion mechanism 300 includes a main push rod 360 disposed in the limiting vertical plate 230, a second traction member 370 is disposed at the outer end of the main push rod 360, a clamp 380 is disposed at the bottom end of the second traction member 370, a T-shaped slider is disposed on the top of the clamp 380, and the T-shaped slider is adapted to penetrate into the slide groove of the stabilizing slide rail 240, and column heads are disposed on both sides of the clamp 380; Two symmetrically distributed slide plates are disposed outside the main push rod 360, and the slide plates are adapted to penetrate the interior of the limiting vertical plate 230; Through holes are formed at both ends of the main push rod 360 and inside the clamp 380 , and bearings 390 are disposed in the through holes.

[0027] The driving mechanism 400 includes a chassis 410 disposed on the top of the supporting plate 310, a motor 420 disposed in the chassis 410, a rotating wheel 430 mounted on the outer end of the transmission shaft in the motor 420, a traction plate 440 movably mounted on the rotating wheel 430, and a striker 450 movably connected to the other end of the traction plate 440; The amplitude vibration mechanism 500 includes a frequency vibration plate 530, a plurality of vertical rods 510 disposed in the frequency vibration plate 530, and a compression spring 520 disposed outside the vertical rods 510; The vertical rod 510 is made of stainless steel.

[0028] The auxiliary flattening mechanism 600 includes two pressure-boosting rollers 620 movably mounted in the two main push rods 360 , two driving rollers 610 disposed in the four clamps 380 , and a chain belt plate 630 drivingly connected to the driving rollers 610 and the outside of the pressure-boosting rollers 620 ; The frequency vibration plate 530 is located on the inner side of the chain belt plate 630, and the two booster rollers 620 are arranged at both ends of the two main push rods 360; The driving roller 610 is disposed in two adjacent clamping heads 380 .

[0029] Since the steel strips 100 of different thicknesses need to be immersed in the 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, the plated steel strips 100 are cooled by an external cooling medium; After the steel belt 100 passes through the top of the pressure plate 220, the chain plate 630 attached to the top of the steel belt 100 can provide it with a stable lateral limit protection. After the external driving device transmits one of the second gears 650, the two driving rollers 610 can cooperate with the chain 660 to achieve the same speed rotation. At this time, the chain plate 630 can provide a large-area boost to the top of the steel belt 100. At the same time, after the frequency vibration plate 530 arranged on the inner side of the chain plate 630 is attached to the inner side of the chain plate 630, the frequency vibration plate 530 hit by the striker 450 at a high frequency can vibrate the part of the chain plate 630 attached to the top of the steel belt 100. At this time, the rotating chain plate 630 can cooperate with the frequency vibration plate 530 to effectively flatten the lead layer on the surface of the steel belt 100; When it is necessary to process steel strips 100 of different thicknesses, the hydraulic component 320 can be operated until the hydraulic sub-rod in the hydraulic component 320 pushes the support plate 330 to rise and fall stably, and finally the multiple first traction components 350 and the multiple second traction components 370 can provide equally spaced assisting forces to the two boosting rollers 620 and the two driving rollers 610. At this time, the thinner steel strip 100 can avoid abnormal shaking during the leveling of the lead layer, thereby avoiding abnormal friction between the shaking steel strip 100 and the boosting component.

[0030] Embodiment 2: Combination Figures 2 to 6As shown, based on the embodiment 1, the belt surface pressure assisting mechanism 200 further includes two groups of belt distance control components 280; The belt distance control assembly 280 includes a second base 282 mounted on the load-bearing beam rail 210 , a first base 281 disposed on the stabilizing slide rail 240 , and a distance control pad 283 disposed between the first base 281 and the second base 282 ; The top and bottom ends of the distance control pad 283 are both provided with inclined surfaces, and a plurality of evenly distributed vertical holes are provided inside the distance control pad 283 , and combination bolts 284 are provided in the vertical holes.

[0031] Preferably, steel belts 100 of different thicknesses are adjusted by four combination bolts 284 and four distance control pads 283. As the top and bottom inclined surfaces of the distance control pads 283 are adapted to the end surfaces of the first base 281 and the second base 282, the combination bolts 284 can finally be effectively fixed. At this time, a constant gap can be maintained between the load-bearing beam rail 210 and the chain belt plate 630, thereby preventing the steel belt 100 from being subjected to excessive pressure and abnormal deformation during the vibration and lateral movement.

[0032] The inner end of the stabilizing slide rail 240 is provided with two symmetrically distributed holes, and the vertical rod 510 is adapted to penetrate through the holes; The bottom end of the compression spring 520 is adapted to bear pressure on the top of the stabilizing slide rail 240 .

[0033] Preferably, the stabilizing slide rail 240 is fixedly mounted on the limiting vertical plate 230, and the frequency vibration plate 530 supported by multiple compression springs 520 can be adapted to fit the inner side of the chain plate 630 in the initial state. As the striker 450 hits the frequency vibration plate 530, the frequency vibration plate 530 as a whole can vibrate slightly in the middle of the four stabilizing slide rails 240, thereby ensuring that the rotating chain plate 630 can resonate the steel belt 100 over a large area.

[0034] Embodiment 3: Combination Figure 4 and Figure 7 As shown, on the basis of Example 1, the bandwidth expansion mechanism 300 further includes a top support plate 310 installed on the top of the limiting vertical plate 230, a hydraulic component 320 is arranged in the middle of the top support plate 310, and a supporting plate 330 is arranged on the hydraulic sub-rod in the hydraulic component 320; The first traction members 350 are movably connected to the ends of both ends of the support plate 330 .

[0035] Preferably, four feet are installed on the four ends of the bottom of the top support plate 310, and the four feet are fixed to the top of the limiting vertical plate 230 by bolts. At this time, the top support plate 310 can provide an effective suspension support platform for the auxiliary flattening mechanism 600.

[0036] The other end of the first traction member 350 is movably mounted on the end of the outer end of the slide plate; A sheath 340 is provided at one end of the hydraulic component 320; The striker 450 is adapted to penetrate into the interior of the sheath 340, and the bottom end of the striker 450 is adapted to bear pressure on the top of the frequency vibration plate 530; A groove is formed on one side of the supporting plate 310 , and the top end of the striker 450 is located in the groove.

[0037] Preferably, the chuck 380 is movably installed in the stabilizing rail 240 , and the limiting rod 260 is adapted to penetrate into the transverse hole inside the chuck 380 , and one end of the spring 270 is connected to the inner wall of the stabilizing rail 240 , and the other end of the spring 270 is connected to the chuck 380 .

[0038] Embodiment 4: Combination Figures 7 to 9 As shown, in the above embodiment, the auxiliary flattening mechanism 600 further includes a first gear 640 and a second gear 650 disposed on a shaft at one end of the driving roller 610; The two first gears 640 are transmission-connected with a chain 660 .

[0039] Preferably, the driving roller 610 and the boosting roller 620 are both composed of a horizontal shaft and an I-shaped sleeve roller, and two bearings 390 are installed at both ends of the horizontal shaft; The chain belt plate 630 is composed of a plurality of blades and a plurality of insert rods to form a transmission belt structure.

[0040] The working principle and use process of the present invention are as follows: after the steel strip 100 is heated to the austenitizing temperature, it is in a state between liquid and semi-solid, and then the steel strip 100 in this state is delivered to the molten lead liquid, and the heated steel strip 100 is immersed in the lead solution and left to stand for a period of time until a layer of lead is evenly provided on the surface of the steel strip, and then the lead-immersed steel strip is quickly cooled by a cooling medium until the isothermal structure of the steel strip is transformed, and then the steel strip can be delivered to the top of the two load-bearing beam rails 210 and the pressure plate 220, and at this time, the sunken chain belt plate 630 is adapted to fit the top surface of the steel strip; By using an external driving device to drive one of the second gears 650, the first gear 640 can obtain effective transmission of the chain 660, and with the two booster rollers 620 tightening and supporting the chain belt plate 630, the driven chain belt plate 630 can help the steel belt 100 to move horizontally at a uniform speed; When the motor 420 is started and running, its internal transmission shaft will start the rotating wheel 430 to rotate at high speed. At this time, the traction plate 440 movably installed on the column deviating from the center of the rotating wheel 430 will drive the striker 450 to reciprocate and rise and fall. The striker 450 can apply an impact force to the frequency vibration plate 530 under the limit and stabilization of the sheath 340. The frequency vibration plate 530 can vibrate the part of the chain plate 630 that is attached to the top surface of the steel belt 100 when it is impacted with high frequency. Under the impact and vibration, the frequency vibration plate 530 and the pressure plate 220 can vibrate and grind the lead protrusions or burrs on the top and bottom surfaces of the steel belt 100. When it is necessary to process steel strips 100 of different thicknesses, operate the hydraulic component 320 until the hydraulic sub-rod in the hydraulic component 320 pushes the support plate 330 to descend as a whole, and finally the support plate 330 will push the four first traction members 350 at the same time, and the two pushed main push rods 360 will push the four second traction members 370 at the same time, and finally the two driving rollers 610 and the two boosting rollers 620 will be pressed and sink until the chain belt plate 630 increases the contact area with the steel strip. At this time, the thinner steel strip 100 can avoid abnormal shaking of the exposed part during the flattening of the lead layer, thereby reducing the problem of wear of the lead layer caused by the shaking of the steel strip, and then the lead layer on the surface of the steel strip can be flattened by strong pressure.
