Description

Technical Field

[0001] The invention relates to the technical field of rolling mill component production, in particular to an automatic slag cleaning rolling mill production line. Background Art

[0002] A rolling mill is a device that realizes the metal rolling process. It generally refers to the equipment that completes the entire process of rolling production. In the production of rolling mills, some parts are formed by metal casting, while some parts are obtained by sand casting. After sand casting, it is usually necessary to demold the casting from the casting sand.

[0003] With reference to a Chinese patent with application number 201911282954.5, a demoulding device for sand mold casting is disclosed, which adopts a method of first vibrating and then separating the sand box and the casting from bottom to top for demoulding, eliminating the defect that the casting is easily damaged due to excessive demoulding force when the ejection mechanism is used for demoulding, and the demoulding mechanism can be guided during demoulding to avoid the situation where the sand box is skewed and the surface of the casting is scratched. The above-mentioned demoulding device for sand mold casting lacks demoulding means for the inner cavity of the casting. The casting sand in the inner cavity of the casting is solidified inside and still needs to be cleaned manually. The demoulding method currently adopted by foundries is generally to knock on the casting to vibrate and fall off the casting sand in the inner cavity of the casting. It is not easy to control the knocking force during the operation of this method, and excessive knocking force can easily cause damage to the casting.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 9 The technical solution provided by the present invention specifically includes the following embodiments: An automatic slag cleaning rolling mill production line includes a profile frame 100, a demolding component 200 and a shaking component 300. The demolding component 200 is rotatably arranged inside the profile frame 100 and is used for demolding the rolling mill casting.

[0020] For further details, please refer to Figure 7 , Fig. 9 As shown: The demolding component 200 includes a torsion sleeve 201, a torsion inner core 202, a prismatic hole 203, a prismatic rod 204, a crushing head 205 and a spring 206. The torsion sleeve 201 is located inside the profile frame 100, the torsion inner core 202 is rotatably installed inside the torsion sleeve 201, a connector 400 is fixedly installed on the upper part of the outer wall of the torsion inner core 202, the prismatic hole 203 is opened in the middle of the top of the torsion inner core 202, the prismatic rod 204 is slidably installed inside the prismatic hole 203, a limiting ring 2023 is fixedly installed on the upper part of the outer wall of the prismatic rod 204, the crushing head 205 is fixedly installed on the top of the prismatic rod 204, the spring 206 is located inside the prismatic hole 203, and is fixedly installed between the bottom wall of the prismatic hole 203 and the bottom of the prismatic rod 204.

[0021] Specifically, the profile frame 100 is fixedly connected to the fixed frame on the rolling mill production line. When the rolling mill casting is demoulded, the casting is placed on the top of the casting fixing table 500 so that the mouth of its inner cavity faces downward. Initially, the casting sand inside the casting is against the top of the crushing head 205, and the crushing head 205 and the prismatic rod 204 are pressed downward, causing the prismatic rod 204 to slide downward along the inner wall of the prismatic hole 203, thereby compressing the spring 206 to generate a rebound force until the casting contacts the top of the casting fixing table 500 and fixes it (the fixing method may include but is not limited to electric clamps and pneumatic clamps for clamping and fixing the casting, which are all prior art). , no further details are given), the torsion inner core 202 rotates inside the torsion sleeve 201, and the rotation of the torsion inner core 202 drives the prismatic hole 203 to rotate together, and further under the torsion limiting effect of the edges and corners of the prismatic hole 203 and the edges and corners of the prismatic rod 204, drives the prismatic rod 204 to rotate together with the crushing head 205, and the crushing head 205 rotates to drill holes in the casting sand in the inner cavity of the casting, during which part of the casting sand falls downward to the top of the torsion inner core 202, and is thrown to the top of the connecting shaker 400 under the action of centrifugal force, and is thrown out to the periphery through the connecting shaker 400. In order to prevent the thrown casting sand from splashing and injuring people, a retaining ring can be set on the periphery of the profile frame 100.

[0022] For further details, please refer to Figure 3 to Figure 8 As shown: The demoulding component 200 further includes a receiving hole 207, an elastic crushing scraper 208, a prismatic sliding sleeve 209, a mounting notch 2010, a bearing seat 2011, a torsion shaft 2012, a feed wheel 2013, an annular groove 2014, a helical tooth 2015, a positioning sleeve 2016, a spiral tooth 2017, a motor compartment 2018, a power motor 2019, a driving gear 2020 and a driven gear ring 2021. The receiving holes 207 are arranged in a circular array on the top of the torsion inner core 202, and the elastic crushing scraper 208 slides. The prismatic sleeve 209 is installed inside the plurality of receiving holes 207, the prismatic sleeve 209 is slidably installed on the top of the plurality of elastic crushing scraping strips 208, and is slidably installed on the outer wall of the prismatic rod 204, the installation slots 2010 are arranged on the outer wall of the torsion inner core 202 in a circular array, and correspond to the positions of the receiving holes 207 one by one, the installation slots 2010 are connected to the inside of the receiving holes 207 at the corresponding positions, the bearing seat 2011 is fixedly installed on the outer wall of the torsion inner core 202 with the midline of the installation slots 2010 symmetrically distributed on the left and right sides, and the torsion inner core 202 is fixedly installed on the outer wall of the torsion inner core 202. The rotating shaft 2012 is rotatably mounted inside the two bearing seats 2011, the feed wheel 2013 is fixedly mounted in the middle of the outer wall of the torsion shaft 2012, the annular groove 2014 is provided on the outer wall of the feed wheel 2013, the inner wall of the annular groove 2014 abuts against the outer wall of the elastic crushing scraper 208 at the corresponding position, the helical teeth 2015 are provided on the outer wall of the feed wheel 2013, the positioning sleeve 2016 is fixedly mounted on the top of the torsion sleeve 201 and is located on the periphery of the torsion inner core 202, and the spiral teeth 2017 are provided on the positioning sleeve 2016. On the inner wall, the spiral teeth 2017 are meshed with the helical teeth 2015, the motor compartment 2018 is opened at the lower part of the outer wall of the torsion sleeve 201, the power motor 2019 is fixedly installed inside the motor compartment 2018, and the output shaft of the power motor 2019 is movably extended to the bottom periphery of the torsion sleeve 201, the driving gear 2020 is fixedly installed at the bottom of the output shaft of the power motor 2019, and the driven gear ring 2021 is fixedly installed at the lower part of the outer wall of the torsion inner core 202, and the driven gear ring 2021 is meshed with the driving gear 2020.

[0023] Specifically, the output shaft of the power motor 2019 drives the driving gear 2020 to rotate, which further drives the driven gear ring 2021 meshing therewith to rotate. The rotation of the driven gear ring 2021 drives the torsion inner core 202 to rotate inside the torsion sleeve 201. The rotation of the torsion inner core 202 drives the prismatic hole 203 to rotate together. At the same time, the rotation of the torsion inner core 202 also drives the multiple storage holes 207 together with the multiple elastic crushing scrapers 208 to rotate together, and the torsion inner core 202 also drives the torsion shaft 2012 and the feed wheel 2013 to rotate together through the bearing seat 2011, and the rotation of the feed wheel 2013 will drive the helical teeth 2015 to rotate together. Due to the meshing action of the helical teeth 2015 and the spiral teeth 217, the helical teeth 2015 rotate with the feed wheel 2013 and push the feed wheel 2013 to rotate along the connection between the bearing seat 2011 and the torsion shaft 2012. , and drives the annular groove 2014 to rotate together, and under the friction force between the inner wall of the annular groove 2014 and the outer wall of the elastic crushing scraper 208, the elastic crushing scraper 208 and the prismatic sliding sleeve 209 are pushed upward along the inner wall of the receiving hole 207, so that the elastic crushing scraper 208 enters the hole drilled by the crushing head 205, until the top of the prismatic sliding sleeve 209 abuts against the bottom of the limit ring 2023, as the elastic crushing scraper 208 continues to move upward, multiple elastic crushing scrapers 208 all expand toward the periphery under the action of their own toughness, thereby abutting against the inner wall of the hole drilled by the crushing head 205, and as the torsion inner core 202 continues to rotate, it drives multiple elastic crushing scrapers 208 to rotate, causing the elastic crushing scraper 208 to continuously rub the remaining casting sand in the inner cavity of the casting, loosening the remaining casting sand in the inner cavity of the casting, causing it to fall off from the inner cavity of the casting, completing the demoulding of the casting.

[0024] For further details, please refer to Figure 7 As shown: The demolding component 200 also includes storage tubes 2022 , which are fixedly installed at the bottom of the twisted inner core 202 in a circular array distribution, and their positions correspond one-to-one to the positions of the prismatic holes 203 . The interior of the storage tubes 2022 is connected to the interior of the prismatic holes 203 .

[0025] Specifically, a storage tube 2022 is provided to limit the bottom of the elastic crushing scraper 208, thereby increasing the storage space at the bottom of the elastic crushing scraper 208, ensuring that when the inner core 202 is twisted to drive the elastic crushing scraper 208 to rotate, the bottom of the elastic crushing scraper 208 will not be thrown out to the periphery due to the centrifugal force.

[0026] For further details, please refer to Figure 2 to Figure 6 as well as Fig.10 As shown: The shaking component 300 includes a through slot 301, a ring channel 3001, a fixed plate 302, an interlaced abutment 303, a swivel 304, a protrusion 305, a first hinge seat 306, a second hinge seat 307 and an elastic telescopic rod 308. The through slots 301 are arranged on the outer wall of the torsion sleeve 201 in a circular array, and the number is three. The ring channel 3001 is arranged on the inner wall of the torsion sleeve 201 and is connected to the inside of the through slot 301. The fixed plates 302 are fixedly installed on the inner wall of the profile frame 100 in a circular array distribution, the number is three, and the positions correspond to the through slots 301 one by one. The interlaced abutment 303 is fixedly installed on the lower part of the inner side surface of the fixed plate 302. The interlaced abutment 303 is fixedly installed on the inner side surface of the fixed plate 302. 03 is inserted into the through slot 301 at the corresponding position and extends to the inside of the annular channel 3001. The outer wall of the inserted abutment strip 303 and the inner wall of the through slot 301 are clearance-matched. The swivel 304 is fixedly mounted on the outer wall of the torsion inner core 202 and is located inside the annular channel 3001. The protrusion 305 is fixedly mounted on the outer wall of the swivel 304. The No. 1 hinge seat 306 is fixedly mounted on the inner wall of the profile frame 100 in a circular array distribution, and there are three of them. The No. 2 hinge seat 307 is fixedly mounted on the lower part of the outer wall of the torsion sleeve 201 in a circular array distribution, and there are three of them. The elastic telescopic rod 308 is hinged between the No. 1 hinge seat 306 and the No. 2 hinge seat 307 through a ball head.

[0027] Specifically, the torsion inner core 202 rotates, driving the swivel 304 and the protrusion 305 to rotate. During the rotation of the protrusion 305, it contacts the ends of the three interlaced abutments 303 in a cyclic and alternating manner, generating a thrust along the radial direction of the torsion inner core 202 on the interlaced abutments 303. Under the reaction force of the interlaced abutments 303 on the protrusion 305 and the elastic support of the three elastic telescopic rods 308, the torsion sleeve 201 vibrates horizontally inside the profile frame 100, further causing the demolding component 200 to vibrate as a whole, causing the elastic crushing scraper 208 to continuously strike the casting sand in the inner cavity of the casting, thereby improving the demolding efficiency.

[0028] In the present scheme, an automatic slag cleaning rolling mill production line is fixedly connected to a fixed frame on the rolling mill production line through a profile frame 100 when working. When the rolling mill casting is demoulded, the casting is placed on the top of the casting fixed platform 500 with the mouth of its inner cavity facing downward. Initially, the casting sand inside the casting abuts against the top of the crushing head 205, squeezing the crushing head 205 together with the prismatic rod 204 downward, causing the prismatic rod 204 to slide downward along the inner wall of the prismatic hole 203, thereby compressing the spring 206 to generate a rebound force until the casting contacts the top of the casting fixed platform 500 and fixes it. The power motor 219 is started, and the output shaft of the power motor 219 drives the driving gear 2020 to rotate, which further drives the driven gear ring 2021 meshing therewith to rotate. The rotation of the driven gear ring 2021 drives the torsion inner core 202 to rotate inside the torsion sleeve 201. The rotation of the torsion inner core 202 drives the prismatic hole 203 to rotate together. Further, under the torsion limiting effect of the edges and corners of the prismatic hole 203 and the edges and corners of the prismatic rod 204, the prismatic rod 204 is driven to rotate together with the crushing head 205, and the crushing head 205 rotates toward the inner cavity of the casting. During the drilling of the casting sand inside, a part of the casting sand falls down to the top of the torsion inner core 202, and is thrown to the top of the connecting shaker 400 under the action of centrifugal force, and is thrown out to the periphery through the connecting shaker 400. At the same time, the rotation of the torsion inner core 202 also drives the multiple storage holes 207 together with the multiple elastic crushing scrapers 208 to rotate, and the torsion inner core 202 also drives the torsion shaft 2012 and the feed wheel 2013 to rotate together through the bearing seat 2011, and the rotation of the feed wheel 2013 drives the bevel gear 2015 to rotate together. Under the meshing action of the helical teeth 2015 and the helical teeth 2017, the helical teeth 2015 cause the feed wheel 2013 to rotate along the connection between the bearing seat 2011 and the torsion shaft 2012, and drive the annular groove 2014 to rotate together, and under the friction between the inner wall of the annular groove 2014 and the outer wall of the elastic crushing scraper 208, the elastic crushing scraper 208 and the prismatic sliding sleeve 209 are pushed upward along the inner wall of the receiving hole 207, so that the elastic crushing scraper 208 enters the hole drilled by the crushing head 205. The elastic crushing scraper 208 is moved upward until the top of the prismatic sliding sleeve 209 contacts the bottom of the limiting ring 2023. As the elastic crushing scraper 208 continues to move upward, the multiple elastic crushing scraper 208 expands toward the periphery due to their own toughness, thereby contacting the inner wall of the hole drilled by the crushing head 205. As the twisting inner core 202 continues to rotate, the multiple elastic crushing scraper 208 are driven to rotate, causing the elastic crushing scraper 208 to continuously rub the remaining casting sand in the inner cavity of the casting, loosening the remaining casting sand in the inner cavity of the casting, so that the inner cavity of the casting is demolded from the casting sand mold; During this period, the rotation of the torsion inner core 202 also drives the rotation of the swivel 304 and the protrusion 305. During the rotation of the protrusion 305, it cyclically and alternately contacts the ends of the three interlaced abutments 303, generating a thrust along the radial direction of the torsion inner core 202 on the interlaced abutments 303. Under the reaction force of the interlaced abutments 303 on the protrusion 305 and the elastic support of the three elastic telescopic rods 308, the torsion sleeve 201 vibrates horizontally inside the profile frame 100, further causing the demolding component 200 to vibrate as a whole, causing the elastic crushing scraper 208 to continuously strike the casting sand in the inner cavity of the casting, thereby improving the demolding efficiency.

[0029] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
