Precise splitting machine for ultrathin steel strip

Abstract

The invention belongs to the technical field of steel belt slitting equipment, and particularly relates to an ultrathin steel belt precision slitting machine which comprises a butt joint component, a cutting component is arranged below the butt joint component, a rolling component is arranged on the back of the cutting component, and the butt joint component comprises a vertical support. The top of the inner wall of the vertical support is fixedly connected with a traction sleeve, and the bottom of an inner cavity of the traction sleeve is fixedly connected with a segmented tension column. Due to the fact that when the sharp edge of the cutting component is in butt joint with the annular cutting groove of the grooving long barrel shell, the cut side of the steel belt can be brought into the annular cutting groove of the grooving long barrel shell, the cut face of the cut steel belt is prone to being bent towards the concave position, and the cut steel belt is integrally in an arc-shaped bent strip shape instead of an irregular plane belt. Due to the fact that the guide sliding plate is arranged at the outlet of the steel belt, the steel belt can be rolled by the three sets of extrusion roller shafts after passing through the guide sliding plate, the steel belt wound by the storage winding shaft is smooth, and the problem that the wound steel belt is prone to bulging is avoided.

Description

Technical Field

[0001] The invention belongs to the technical field of steel strip slitting equipment, in particular to an ultra-thin steel strip precision slitting machine. Background Art

[0002] Steel belt refers to a conveyor belt made of carbon steel as the traction and carrying component of the belt conveyor. It is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Steel belts are divided into two categories according to the material used: ordinary strip steel and high-quality strip steel. Existing industrial steel forming machines generally shear the steel belt through the shearing mechanism on it to obtain a long steel belt of a certain width.

[0003] When existing equipment cuts wider steel strips, the steel strip will pass through the groove of the cutting wheel body, so its edge after cutting is easy to bend to one side relative to the main plane, which causes the cut steel strip to be an arc-shaped curved strip instead of a regular flat strip. The uneven steel strip is easy to bulge when laid and used, resulting in a series of problems such as uneven paving surface, so improvement is needed. Summary of the invention

The outer surface of the notched long cylindrical shell is plugged into the inner wall of the circular cutting drum through the cutting component, the bottom end of the fixed bracket is fixedly connected to the bottom of the inner wall of the vertical bracket, and the outer surface of the concentrating plate is fixedly connected to the outer surface of the fixed bracket.

[0009] Furthermore, the special plug plate includes a long connecting plate, the lower surface of the long connecting plate is evenly provided with arc plug plates, the front and rear sides of the lower surface of the long connecting plate are symmetrically provided with reset spring belts, the inner cavity of the arc plug plate is evenly provided with vertical connecting ports, and the vertical connecting ports extend to the outside of the long connecting plate, the vertical connecting ports penetrate the long connecting plate and the arc plug plate, and the high-pressure gas inside the protective partition can be discharged through the vertical connecting ports.

[0010] Furthermore, the cutting component includes a built-in sleeve, the outer surface of the built-in sleeve is fixedly connected to an adapter pulley through a connecting rod, the outer surface of the adapter pulley is fixedly connected to an annular cutting blade, the outer surface of the adapter pulley is slidably connected to the inner wall of the grooved long cylinder shell through a cutting groove, each cutting component is relatively independent, and the annular cutting blade is a sharp annular structure, which can cut the steel belt by rolling, and the annular cutting blade can be inserted into any annular cutting groove of the circular cutting drum.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. When the device is used to slit wider steel strips, the steel strip passing through can be slit into narrower thin steel strips through the cutting component. When the sharp edge of the cutting component is butted against the annular groove of the grooved long cylinder shell, the cut side of the steel strip will be brought into the annular groove of the grooved long cylinder shell, which will cause the cut surface of the steel strip to be easily bent toward the concave part after cutting, resulting in the overall shape of the cut steel strip being an arc-shaped curved strip rather than a regular flat strip. Therefore, a guide slide is set at the exit position of the steel strip. The steel strip passing through the guide slide will be rolled by three sets of extrusion rollers to make the steel strip wound by the storage reel relatively flat, avoiding the problem of the steel strip being easily bulging after winding.

[0014] 2. The steel strips after cutting tend to scatter and are difficult to collect, so a guide slide is used to gather the loose steel strips together. When the steel strips slide out from the bottom of the guide slide, they will be scanned by scanners on both sides. Then, the spacing between the extrusion rollers on both sides will be adjusted according to the flatness of the steel strips, thereby changing the rolling force of the extrusion rollers on the steel strips. Under the premise of ensuring that the extrusion rollers can flatten the steel strips, the problem of the extrusion rollers rolling the steel strips too thin, which may cause the steel strips to break easily, can be avoided.

[0015] 3. After the slitting process, the annular groove of the grooved long cylindrical shell may have metal debris generated by the cutting of the metal steel strip, which needs to be cleaned in time. Otherwise, the metal debris will be trapped in the deep annular groove and difficult to remove, which will cause the annular groove of the grooved long cylindrical shell to be unable to dock with the cutting component normally. Therefore, the protective partition is improved. During the up and down movement of the circular cutting drum, the annular groove of the circular cutting drum can be cleaned by inserting an arc-shaped plug plate, thereby solving the problem of internal metal debris retention.

[0016] 4. During normal operation, the spacing between each cutting component is the same, ensuring that the size of the steel strip after cutting is the same. The device can adjust the position of the cutting point of the cutting component, thereby changing the width of the evenly divided steel strip and obtaining steel strips of different sizes. Since the compression tubes controlled by the pressure pump are interconnected, when the overall pressure is fixed, the spacing between the adjusted cutting components will also be the same, thereby ensuring that the size of the steel strip after cutting is the same and achieving a precise cutting effect.

[0028] The docking component 1 includes a vertical bracket 11, a traction sleeve 12 is fixedly connected to the top of the inner wall of the vertical bracket 11, a segmented tension column 13 is fixedly connected to the bottom of the inner cavity of the traction sleeve 12, a protective baffle 15 is fixedly connected to the bottom of the outer surface of the segmented tension column 13, and force-bearing push plates 16 are symmetrically arranged on the front and rear sides of the inner cavity of the protective baffle 15, and pressure belts 17 are symmetrically arranged on the front and rear sides of the inner wall of the protective baffle 15. A special plug plate 4 is arranged in the middle of the inner wall of the protective baffle 15. The force-bearing push plate 16 can be pressurized by pressing the pressure belt 17 inward to push the special plug plate 4 downward. The bottom end of the segmented tension column 13 is fixedly connected to a ring cutting drum 18 through a lateral motor. The ring cutting drum 18 keeps a certain distance from the upper protective baffle 15 to prevent the ring cutting drum 18 from rubbing against the protective baffle 15 when rotating. The upper part of the outer surface of the vertical bracket 11 is fixedly connected to a baffle rod side plate 14;

[0029] The cutting component 2 includes a fixed bracket 21, the top end of which is fixedly connected to a groove cutting long cylindrical shell 22 through a lateral motor, and the inner wall of the groove cutting long cylindrical shell 22 is evenly provided with cutting components 23, which can dock with each groove of the circular cutting drum 18 to cut the passing steel strip, and a control push rod 24 is provided at the axis center of the inner wall of the groove cutting long cylindrical shell 22.

[0030] The rolling component 3 includes a concentrating plate 31 and a guide slide 32. The main body of the guide slide 32 is a hollow semicircular arc structure, with a horizontal structure on the top for guiding the steel strip to enter, and a vertical structure on the bottom for guiding the steel strip to slide out. The inner wall of the guide slide 32 is evenly provided with extrusion rollers 34 through rotating grooves, and both ends of the extrusion rollers 34 are fixedly connected with bunching motors 33. Each bunching motor 33 can limit the two extrusion rollers 34 and connect them together, and control the extrusion rollers 34 to rotate. A scanner 35 is symmetrically arranged at the bottom of the inner cavity of the guide slide 32. The scanner 35 can scan and detect the steel strip passing through this position. The bottom of the inner cavity of the concentrating plate 31 is rotatably connected with a storage reel 36.

[0031] There are two baffle side plates 14, and the outer surface of the baffle side plates 14 and the outer surface of the force-bearing push plate 16 are pressed against each other. The end of the force-bearing push plate 16 away from the pressure belt 17 extends to the outside of the protective partition 15 through the notch. The front and rear sides of the outer surface of the protective partition 15 are slidably connected to the inner wall of the vertical bracket 11. The outer surface of the notched long cylindrical shell 22 is plugged into the inner wall of the circular cutting drum 18 through the cutting component 23, the bottom end of the fixed bracket 21 is fixedly connected to the bottom of the inner wall of the vertical bracket 11, and the outer surface of the concentrating plate 31 is fixedly connected to the outer surface of the fixed bracket 21. There are six extrusion rollers 34, the outer surface of which is fixedly connected to the outer surface of the concentrating plate 31, the front and rear sides of the outer surface of the guide slide 32 are fixedly connected to the outer surface of the concentrating plate 31, and the outer surface of the scanner 35 is fixedly connected to the bottom of the inner cavity of the guide slide 32 through the card slot.

[0032] This device is used to cut wider steel strips. First, the steel strip is inserted between the circular cutting drum 18 and the groove cutting long cylindrical shell 22. Since the circular cutting drum 18 and the groove cutting long cylindrical shell 22 perform cutting work through the middle area, the smooth roller structure on both sides is used to push the steel strip to move, so the steel strip is cut when it passes through the cutting component 23, thereby forming a smaller strip of steel strip.

[0033] The cut steel strip will enter the guide slide 32 and slide from top to bottom along the inner wall of the guide slide 32. When passing through the area where the three groups of squeezing rollers 34 are located, the bunching motor 33 will control the squeezing rollers 34 to rotate, thereby rolling the passing steel strip and flattening the bent parts of the side edges of the steel strip. The steel strip that has been repeatedly rolled by the three groups of squeezing rollers 34 will be scanned when passing through the scanner 35. If the steel strip is still bent, the rolling force of the squeezing rollers 34 will be increased. Finally, the cut strip will be rolled up on the outer surface of the storage reel 36.

[0034] Example 2, please refer to Figure 1-Figure 8The present invention provides a technical solution: on the basis of the first embodiment, the special plug plate 4 includes a long connecting plate 41, the lower surface of the long connecting plate 41 is evenly provided with arc plug plates 42, the front and rear sides of the lower surface of the long connecting plate 41 are symmetrically provided with reset spring belts 43, the inner cavity of the arc plug plate 42 is evenly provided with vertical connecting ports, and the vertical connecting ports extend to the outside of the long connecting plate 41, the vertical connecting ports penetrate the long connecting plate 41 and the arc plug plate 42, and the high-pressure gas inside the protective partition 15 can be discharged through the vertical connecting ports. The bottom end of the arc plug plate 42 extends to the outside of the protective partition 15, and the bottom end of the arc plug plate 42 is plugged into the inner wall of the ring cutting drum 18, the bottom end of the reset spring belt 43 is fixedly connected to the bottom of the inner wall of the protective partition 15, and the outer surface of the long connecting plate 41 is slidably connected to the inner wall of the protective partition 15.

[0035] The cutting component 23 includes a built-in sleeve 231, the outer surface of the built-in sleeve 231 is fixedly connected to an adapter pulley 232 through a connecting rod, the outer surface of the adapter pulley 232 is fixedly connected to an annular cutting blade 233, and the outer surface of the adapter pulley 232 is slidingly connected to the inner wall of the grooved long cylindrical shell 22 through a cutting groove. Each cutting component 23 is relatively independent, and the annular cutting blade 233 is a sharp annular structure, which can cut the steel belt by rolling, and the annular cutting blade 233 can be inserted into any annular cutting groove of the circular cutting drum 18.

[0036] The control push rod 24 includes an axial inner tube 241, the inner wall of which is evenly provided with wall-attached slides 242, and both sides of the outer surface of the wall-attached slide 242 are fixedly connected with compression links 244, and the outer surface of the wall-attached slide 242 is fixedly connected with an inner nested ring 243, and the outer surface of the inner nested ring 243 is fixedly connected to the inner wall of the built-in sleeve 231, and the inner wall of the built-in sleeve 231 is slidingly connected to the outer surface of the axial inner tube 241, and both ends of the inner wall of the axial inner tube 241 are fixedly connected with a pressure pump 245, and the air outlet of the pressure pump 245 is fixedly connected to the inner cavity of the compression link 244, and the wall-attached slide 242 slides on the inner wall of the axial inner tube 241, thereby driving the corresponding position of the cutting component 23 to slide along the inner wall of the grooved long cylindrical shell 22.

[0037] After the steel strip is cut, the traction sleeve 12 at the top lifts the protective partition 15 and the ring cutting drum 18 upwards through the segmented tension column 13, increasing the distance between the ring cutting drum 18 and the slotted long cylinder shell 22, so that the lower part of the steel strip is laid on the upper part of the slotted long cylinder shell 22. During the upward sliding process of the protective partition 15, the force-bearing push plates 16 on both sides thereof will continuously contact the baffle rod side plates 14, and then shrink toward the inside of the protective partition 15 under the squeezing effect of the baffle rod side plates 14. At this time, the pressure belt 17 pushes toward the inside of the protective partition 15 to pressurize the area where the special plug plate 4 is located, and then Under the action of pressure, the rear long connecting plate 41 slides down along the inner wall of the protective partition 15, pushing the arc-shaped plug plate 42 to be inserted into each annular groove of the grooved long cylindrical shell 22. During the insertion process, the arc-shaped plug plate 42 will reduce the pressure inside the protective partition 15 through the through-hole, and the ejected gas can be directly blown into each annular groove of the grooved long cylindrical shell 22. At this time, the grooved long cylindrical shell 22 rotates on itself. Without interfering with the rotation of the grooved long cylindrical shell 22, the arc-shaped plug plate 42 can blow away the impurity metal chips embedded in the grooved long cylindrical shell 22, thereby achieving a more comprehensive cleaning work.

[0038] After the force-bearing push plate 16 is separated from the rod body of the baffle side plate 14, the squeezed return spring belt 43 pushes the long connecting plate 41 upward to return the arc-shaped plug plate 42 to its original position. At this time, the arc-shaped plug plate 42 will perform air suction work, but the arc-shaped plug plate 42 has been pulled out from the inside of the grooved long cylindrical shell 22, so the metal impurities inside the grooved long cylindrical shell 22 will not be sucked into the protective partition 15. After the gas inside the protective partition 15 is replenished, the pressurized jet work is performed again until the protective partition 15 stops sliding.

[0039] During normal operation, the spacing between each cutting component 23 is the same, ensuring that the size of the steel strip after cutting is the same. When the size of the cut steel strip needs to be adjusted, the upper grooved long cylindrical shell 22 can be pulled open first, and then the connected compression connecting tube 244 can be pressurized through the internal pressure pump 245 to expand the compression connecting tube 244 and pull the connected wall-attached slide 242 apart. The compression connecting tube 244 can also be contracted by reducing pressure to shorten the spacing between the wall-attached slide 242, thereby pulling each cutting component 23 through the wall-attached slide 242 to achieve the effect of changing the landing point of the annular cutting blade 233 and thereby changing the size of the steel strip after cutting.

[0040] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
