Detailed Description

The technical solutions in the embodiments of the present invention are clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

As shown in fig. 2 to 5, an embodiment of the present invention provides an oil scraping device, which includes a squeeze roller seat 221, a squeeze roller 222 disposed on the squeeze roller seat 221, and a first lifting driving mechanism 223 for driving the squeeze roller seat 221 to lift, wherein the squeeze roller seat 221 is further provided with a plurality of squeeze acting force applying mechanisms, each of the squeeze acting force applying mechanisms is sequentially arranged along an axial direction of the squeeze roller, and output ends of the squeeze acting force applying mechanisms are abutted to inner side roller surfaces of the squeeze roller.

The wringer roller 222 is a device conventional in the art, and its arrangement on the wringer roller base 221 is also a structure conventional in the art, and will not be described in detail here. The first lifting driving mechanism 223 can be a conventional lifting driving device, and in one embodiment, is driven by an air cylinder or a hydraulic cylinder, and the output shaft thereof is axially parallel to the vertical direction, and is generally driven by a set of lifting driving devices at two ends of the wringing roller 222; the first lifting/lowering driving mechanism 223 can drive the wringing roller 222 to approach or depart from the surface of the strip steel, and can control the pressure of the wringing roller 222 on the strip steel, but as mentioned in the background art, the two ends of the wringing roller 222 are pressed down, which easily causes the wringing roller 222 to generate deflection deformation. The bending deformation generated by the wringing roller 222 can be eliminated by applying pressure to the wringing roller body through each wringing acting force applying mechanism; meanwhile, corresponding pressure is applied to different positions of the wringing rollers 222 through each wringing acting force applying mechanism, so that the wringing rollers 222 can be matched with the strip steel plate shape as much as possible, the attaching degree of the wringing rollers 222 and the strip steel surface is improved, the width full-coverage oil removal and the fixed-point accurate oil removal are realized, and the oil removal effect is obviously improved.

The squeezing acting force applying mechanism can adopt a cylinder/a hydraulic cylinder and the like to directly act on the roller body of the squeezing roller. In another preferred embodiment, as shown in fig. 2 and 3, the squeezing force applying mechanism includes a first support roller box 224, a squeezing support roller 2241 provided on the first support roller box 224 and in tangential contact with the inner roller surface of the squeezing roller, and a tightening mechanism for controlling the pressure between the squeezing support roller 2241 and the squeezing roller 222. The squeezing support roll 2241 is in contact with the squeezing roll 222 for pressing, so that on one hand, the pressure action range is large, and the power equipment is in indirect contact with the squeezing support roll 2241 and the squeezing roll 222, so that the damage to the squeezing roll 222 caused by single-point pressing and direct contact pressing of the power equipment is avoided; in addition, the wringing support roller 2241 and the wringing roller 222 are in rolling contact, and the abrasion of the wringing support roller 2241 and the wringing roller 222 is small; on the other hand, the length of the squeeze roll 2241 is designed with high flexibility, and accordingly, the flexibility of the pressure difference differentiation control of the squeeze roll 222 can be improved.

In one embodiment, the number of wringing support rollers 2241 on the first backup roller box 224 can be one, with the one wringing support roller 2241 being positioned directly above the wringing roller 222. In another embodiment, as shown in fig. 3, two wringing support rollers 2241 are arranged on each first support roller box 224, and the two wringing support rollers 2241 are respectively arranged on two sides of the vertical symmetrical plane of the wringing roller 222 and are in tangential contact with the roller surface on the inner side of the wringing roller; wherein, preferably, the tangency positions of the two wringing support rollers 2241 on each first support roller box 224 and the wringing roller 222 are symmetrical relative to the vertical symmetry plane of the wringing roller 222. The two wringing support rollers 2241 are adopted to synchronously press the wringing roller 222, so that the operation reliability is higher, and the running stability of the wringing roller 222 is also higher.

The wringing support roll 2241 is rotatably mounted on the first support roll box 224, and accordingly, a mounting roll frame for mounting the wringing support roll 2241 can be arranged on the first support roll box 224; the squeeze supporting roller 2241 is suspended from the first supporting roller box 224 by mounting a roller frame. On each side of the vertical symmetrical plane of the wringing rollers 222, the wringing support rollers 2241 are generally coaxially arranged, and two adjacent wringing support rollers 2241 on each side are two axially adjacent wringing support rollers 2241; generally, the wringing support rollers 2241 on each side are preferably as close as possible to each other so as to ensure the oil removing effect of the full-width coverage of the strip, however, due to the limitation of the installation structure of the wringing support rollers 2241, for example, when the wringing support rollers 2241 are installed on the installation roller frame, a certain gap is required between two adjacent installation roller frames to ensure the mutual independence of the first support roller boxes 224, that is, a first adjacent gap is formed between every two axially adjacent wringing support rollers 2241, and the first adjacent gap is as small as possible, and at the same time, the interference between two adjacent first support roller boxes 224 is preferably avoided.

The arrangement of the drying support rollers 2241 on the two sides can be symmetrical relative to the vertical symmetry plane of the drying roller 222, for example, two drying support rollers 2241 on each first support roller box 224 have the same length and aligned ends, so that in the axial direction of the drying roller, there are multiple rows of adjacent seam groups, and each row of adjacent seam group includes two first adjacent seams symmetrical relative to the vertical symmetry plane of the drying roller 222; in this scheme, there is a case where the wringing roller 222 between adjacent two first support roller cassettes 224 is in a pressure adjustment blind zone.

In the preferred scheme provided by this embodiment, as shown in fig. 4 and 5, each of the first adjacent seams is sequentially distributed at intervals in the axial direction of the wringing roller, that is, each first adjacent seam can intersect with the wringing support roller 2241 on the other side when extending along the running direction of the strip steel; the pressure action length ranges of the wringing rollers 222 in the two adjacent first supporting roller boxes 224 are partially overlapped, and the wringing roller pressure adjustment blind zone corresponding to each first adjacent seam can be covered and compensated by the wringing supporting roller 2241 on the other side, so that the full-length pressure control of the wringing rollers 222 is realized, and the oil removing effect of the full-width covering of the strip steel is ensured. When the two wringing support rollers 2241 on each first support roller box 224 are the same length, the two wringing support rollers 2241 can be offset in the direction of the wringing roller axis, i.e., the ends are not aligned. In a further embodiment, as shown in fig. 4 and 5, the two wringing support rollers 2241 on the first support roller box 224 are different in length, one of them is a first support roller with a longer length, and the other is a second support roller with a shorter length, and on each side of the vertical symmetry plane of the wringing roller 222, the first support roller and the second support roller are arranged crosswise in sequence; wherein, preferably, in the shaft direction of the drying roll, two ends of the second supporting roll are positioned between two ends of the corresponding first supporting roll. Based on the above scheme, because the lengths of the two wringing support rollers 2241 on the first support roller box 224 are different, the pressure of the first support roller box 224 on the wringing rollers 222 is more uniformly distributed on the wringing roller body, and meanwhile, because the first adjacent seams are sequentially distributed in the axial direction of the wringing rollers, the concentration of the pressure stress on the wringing rollers 222 between the two adjacent first support roller boxes 224 is avoided, and therefore, the scheme can effectively avoid leaving roller marks on the surface of strip steel.

In one embodiment, the first supporting roller box 224 comprises a movable roller car 2243 and a roller box body 2242 arranged on the movable roller car 2243 in a lifting way, the wringing supporting roller 2241 is arranged on the roller box body 2242, and the jacking mechanism is connected with the roller box body 2242; the wringing roller seat 221 is correspondingly provided with a translation track for the movable roller car 2243 to move in a translation manner, and the guide direction of the translation track is parallel to the axial direction of the wringing roller. Based on this structure, the installation and maintenance of the squeeze roll 2241 can be facilitated. Preferably, a locking structure may be provided on the wringing roller seat 221, and after the movable roller 2243 is in place, the position stability of the movable roller 2243 is ensured through the locking structure, and the locking structure may adopt a conventional locking manner, which will not be described herein. During maintenance, the corresponding movable roller car 2243 is pulled out to replace the corresponding wringing support roller 2241. In another embodiment, the squeeze roller seat 221 is further provided with a translation roller carriage, the squeeze rollers 222 and the first support roller boxes 224 are all arranged on the translation roller carriage, and during maintenance, the squeeze rollers 222 and the squeeze support rollers 2241 are pulled out together by the translation roller carriage, so that during offline disassembly maintenance.

Wherein, the walking part can be a roller and can also adopt a slide block form.

The jacking driving unit 225 may adopt conventional linear driving devices such as an air cylinder/a hydraulic cylinder, and the specific structure is not described herein; the jacking driving unit 225 can be fixedly connected with the top rod 2244, and the top rod 2244 is driven to lift by the jacking driving unit 225; this tight drive unit 225 in top also can with the butt of ejector pin 2244, and this tight drive unit 225 in top can order about ejector pin 2244 to push down, and members such as accessible reset spring 2245 make ejector pin 2244 can rise, specifically, be equipped with the confession on the activity roller car 2243 correspondingly the hole of wearing to establish that ejector pin 2244 wears to be equipped with reset spring 2245 on the ejector pin 2244, the both ends of this reset spring 2245 respectively with the spacing portion of the spring on the ejector pin 2244 and the pore wall butt in hole of wearing to establish. The arrangement of the return spring 2245 can not only make the carrier rod 2244 return to adjust the pressure of the wringing roller 222, but also play a role in buffering when the jacking driving unit 225 presses, so as to better protect the wringing support roller 2241 and the wringing roller 222.

The oil scraping device is further optimized, as shown in fig. 2 and 3, and a first water baffle 226 and/or a first purging beam 227 are arranged on the strip outlet side of the wringing roller seat 221.

Furthermore, a strip steel plate shape detection device is arranged on the strip steel inlet side of the oil scraping device, and each squeezing acting force applying mechanism is in interlocking control with the strip steel plate shape detection device. The interlock control is a conventional automatic control method, and is easily realized by a person skilled in the art according to the prior art.

EXAMPLE III

The embodiment of the utility model provides a strip steel plate shape detection device which can be used as the strip steel plate shape detection device in the second embodiment.

Obviously, the second embodiment is not limited to the strip steel plate shape detection device provided in this embodiment, and other plate shape detection methods are also applicable, for example, a laser plate shape detector is used.

The strip steel plate shape detection device preferably adopts a roller type plate shape detection device, and the strip steel is subjected to primary oil removal through the detection roller 232 while the plate shape is detected; two oil removal processes are realized through the detection roller 232 and the wringing roller 222, so that the oil removal effect and efficiency can be further improved.

As shown in fig. 2 and 6, the strip shape detecting device includes a detecting roller seat 231, a detecting roller 232 disposed on the detecting roller seat 231, and a second lifting driving mechanism 235 for driving the detecting roller seat 231 to lift up and down; the detection roller seat 231 is provided with a receiving cavity and receives a plurality of second support roller boxes 2332, the second support roller boxes 2332 are sequentially arranged along the axial direction of the detection roller, each second support roller box 2332 is provided with a detection support roller 2331 which is in tangential contact with the roller surface at the inner side of the detection roller, and a pressure detection device 2334 is arranged between one end of each second support roller box 2332 far away from the detection roller 232 and the inner wall of the receiving cavity.

Preferably, the detection roller 232 and the wringing roller 222 are made of the same material, so that the detection accuracy is improved, and the oil pre-removing effect can be improved.

The second lifting driving mechanism 235 may be a conventional lifting driving device, and in one embodiment, is driven by an air cylinder or a hydraulic cylinder, and an output shaft thereof is axially parallel to the vertical direction, and is generally driven by a set of lifting driving devices at two ends of the detection roller 232; the second lifting driving mechanism 235 can drive the detection roller 232 to be close to or far away from the surface of the strip steel, and can control the pressure of the detection roller 232 on the strip steel; the detection rollers 232 are supported by the detection support rollers 2331, so that the adhesion degree of the detection rollers 232 and the strip steel surface can be improved, the oil pre-removing effect can be improved, the strip steel plate shape can be more accurately reflected, strip steel reaction force received by different positions of the detection rollers 232 can be transmitted to the detection support rollers 2331 at corresponding positions above, and strip steel plate shape detection is better realized. In addition, since the detection support roller 2331 is in tangential contact with the detection roller 232, the friction force between the detection support roller and the detection roller is small, so that not only can the abrasion of the detection roller 232 be reduced, but also the influence of factors such as the friction between the pressure detection device 2334 and the detection roller 232 on the pressure detection accuracy can be avoided.

The arrangement of each detection support roller 2331 may adopt the same arrangement as the above-described extrusion bar support rollers, specifically:

in one embodiment, the number of the test support rollers 2331 on the second support roller box 2332 may be one, and the one test support roller 2331 is positioned directly above the test roller 232. In another embodiment, as shown in fig. 6, two detection support rollers 2331 are disposed on each of the second support roller boxes 2332, and the two detection support rollers 2331 are respectively arranged on two sides of the vertical symmetry plane of the detection roller 232 and are in tangential contact with the inner side roller surface of the detection roller; wherein, preferably, the tangency of the two detection support rollers 2331 on each second support roller box 2332 to the detection roller 232 is symmetrical with respect to the vertical symmetry plane of the detection roller 232. The two detection supporting rollers 2331 are adopted to support and detect the detection roller 232, so that the operation stability of the detection roller 232 is higher, and the plate shape detection accuracy is higher.

The test support roller 2331 is rotatably mounted on a second support roller box 2332, and similarly, a mounting roller frame for mounting the test support roller 2331 may be provided on the second support roller box 2332. On each side of the vertical symmetry plane of the detection roller 232, the detection support rollers 2331 are generally coaxially arranged, and two adjacent detection support rollers 2331 on each side are two axially adjacent detection support rollers 2331; generally, the inspection support rollers 2331 on each side are preferably as close to each other as possible in order to ensure the accuracy of the transverse strip shape inspection, however, due to the limitation of the installation structure of the inspection support rollers, there is a second adjacent gap between two inspection support rollers 2331 adjacent to each axial direction, which is as small as possible while preferably avoiding interference between two adjacent second support roller boxes 2332.

The arrangement of the two detection supporting rollers 2331 on two sides can be symmetrical relative to the vertical symmetry plane of the detection roller 232, for example, two detection supporting rollers 2331 on each second supporting roller box 2332 have the same length and are aligned at the ends, so that in the axial direction of the detection roller, there are a plurality of rows of adjacent seam groups, and each row of adjacent seam group comprises two second adjacent seams which are symmetrical relative to the vertical symmetry plane of the detection roller 232; in this case, there is a case where a pressure detection dead zone exists corresponding to a position between the two second supporting roller boxes 2332.

In the preferred scheme provided by this embodiment, each of the second adjacent seams is sequentially distributed at intervals in the axial direction of the detection roll, that is, each second adjacent seam can intersect with the detection support roll 2331 on the other side when extending along the running direction of the strip steel; in two adjacent second supporting roller boxes 2332, the supporting action length ranges of the detecting rollers 232 are partially overlapped, and the pressure detection blind zone corresponding to each second adjacent seam can be covered and compensated by the detecting supporting roller 2331 on the other side, so that the detection accuracy of the transverse plate shape of the strip steel is ensured. When the two test support rollers 2331 on each second support roller cassette 2332 are the same length, the two test support rollers 2331 may be misaligned in the axial direction of the test rollers, i.e., the ends thereof are not aligned. In another embodiment, the two detection support rollers 2331 on the second support roller box 2332 have different lengths, one of which is a third support roller with a longer length, and the other is a fourth support roller with a shorter length, and the third support roller and the fourth support roller are sequentially arranged in a crossed manner on each side of the vertical symmetry plane of the detection roller 232; wherein, preferably, in the detecting roller axial direction, both ends of the fourth supporting roller are located between both ends of the corresponding third supporting roller. Based on the above scheme, since the two detection support rollers 2331 on the second support roller box 2332 have different lengths and the second adjacent gaps are sequentially distributed in the axial direction of the detection roller, the pressure detection sensitivity at the second support roller box 2332 can be made higher.

Preferably, the distribution of the detection support rollers 2331 in the strip steel plate shape detection device is the same as that of the wringing support rollers 2241 in the oil scraping device, and the detection support rollers correspond to the wringing support rollers 2241 in the oil scraping device one by one, so that the pressure adjustment of the wringing rollers is matched with the strip steel plate shape detection result, and the accuracy of the strip steel oil removal effect is ensured.

Similarly, the second support roller box 2332 is also movable (i.e. can be moved by the movable roller car 2333) to facilitate the installation and maintenance of the test support rollers 2331; reference may be made to the related structure of the first supporting roller box 224, which is not described herein.

The conventional pressure detecting device 2334 is suitable for this embodiment, and in one embodiment, the pressure detecting device 2334 is an elastic pressure detecting device.

Further, as shown in fig. 2 and fig. 6, a second water baffle 234 and/or a second purging beam 236 are disposed on the strip outlet side of the detection roller seat 231; the second water baffle 234 is arranged to effectively inhibit the emulsion from splashing; the second purging beam 236 can blow off the emulsion remaining on the surface of the strip steel, so as to further improve the oil removing effect, and meanwhile, when the strip steel plate shape detection device is arranged at the inlet of the rolling mill, the second purging beam 236 can clear away the impurities remaining on the surface of the strip steel and adhered, so as to ensure the surface cleanness of the strip steel.

Further, as shown in fig. 1 and 2, a working fluid spraying beam 237 is disposed on the inlet side of the strip steel of the detection roller seat 231, and can spray emulsion to cool the strip steel during operation, and can also block the emulsion inside the rolling mill from flowing to the outlet side of the unit along with the strip steel.

Preferably, the strip shape detecting device and the oil scraping device may be disposed on the same frame 21.

In general, the transverse plate shape of the upper surface of the strip steel can be mirrored to obtain the transverse plate shape of the lower surface of the strip steel, but preferably, the strip steel oil removing module 2 provided by the second embodiment is adopted for both the upper oil scraping module and the lower oil scraping module, and the strip steel plate shape detection accuracy and the strip steel oil removing effect can be further improved by combining the two modules.
