Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of polishing treatment, and particularly relates to a steel formwork demolding slope polishing treatment device and method. BACKGROUND

[0002] As a core component of industrialized construction in bridge engineering, the geometric precision and apparent quality of the prefabricated pier directly relate to the service performance of the structure. When the prefabricated pier is produced and processed, the staff needs to limit the shape contour and geometric size of the pier component through the steel formwork, so that the pier component poured into shape matches the actual use requirements.

[0003] When a groove needs to be formed on the outer wall of the prefabricated pier, the person skilled in the art usually sets a protruding part similar to the groove on the steel formwork, and a demolding slope is also set on the side of the protruding part, so as to facilitate the separation of the steel formwork with the protruding part from the pier component after pouring and shaping.

[0004] However, the existence of the demolding slope directly increases the polishing difficulty of the steel formwork in the recycling process. Especially when the root of the demolding slope (i.e. the part of the demolding slope close to the steel formwork body) is polished, since there is an included angle between the root of the demolding slope and the steel formwork body, the attachments (such as rust, residual concrete and demolding agent, etc.) are easy to gather at the root of the demolding slope. The gathered attachments generally have a large thickness, which not only easily damages the polishing disc during polishing, thereby causing unnecessary economic losses, but also easily causes polishing residues, thereby affecting the subsequent use effect of the steel formwork.

[0022] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0023] A steel formwork demolding slope polishing treatment device is used for polishing treatment of the demolding slope on the convex peripheral side of the steel formwork, thereby reducing the polishing treatment difficulty of the demolding slope. When there is thick adherent on the root of the demolding slope, the device not only can protect the polishing disc, but also can polish the thick adherent twice in succession, thereby improving the polishing quality of the root of the demolding slope and avoiding the residual adherent.

[0024] Specifically, the steel formwork demolding slope polishing treatment device in the embodiment includes a bearing plate 2, a polishing unit and an adjusting unit. As shown in the drawing, Figure 1 The bearing plate 2 is connected with the walking unit 1 through the adjusting unit, and the polishing unit is arranged on the bearing plate 2. When in use, the adjusting unit can adjust the posture of the bearing plate 2, so that the device forms a working posture as shown in the drawing, Figure 2 Figure 2 ​When the walking unit 1 is hidden in the polishing unit 2, the bearing plate 2 will be parallel to the demolding slope 92, and the polishing unit on the bearing plate 2 will be in contact with the demolding slope 92. When the polishing unit is started, the walking unit 1 will travel along the intersection line between the demolding slope 92 and the steel formwork body 91, thereby polishing the demolding slope 92.

[0025] It should be noted that the walking unit 1 in the embodiment can be a wall-climbing robot or other mature automatic mobile operation equipment in the prior art. The specific working principle, component structure and control method of the walking unit 1 are well known to the public and do not belong to the invention content of the present application, so they will not be described in detail herein.

[0026] In actual application, the demolding slope 92 and the steel formwork body 91 usually have a certain inclination angle, the inclination angles of different demolding slopes 92 are different, and the overall size specifications of the demolding slopes 92 also differ. Therefore, in order to ensure that the device can adapt to different demolding slopes 92 and ensure that the bearing plate 2 can be flexibly adjusted according to the actual situation of the demolding slope 92, as shown in FIG. 8, the adjusting unit can include a first adjusting plate 81, a second adjusting plate 82 and a third adjusting plate 83. Figure 3

[0027] The first adjusting plate 81 is detachably arranged on the walking unit 1 by bolt connection, the second adjusting plate 82 is arranged on one side of the first adjusting plate 81, and the second adjusting plate 82 is perpendicular to the first adjusting plate 81. The third adjusting plate 83 is arranged on the second adjusting plate 82 in a lifting manner, and the third adjusting plate 83 is parallel to the first adjusting plate 81, so as to adjust the height of the bearing plate 2 by the lifting action of the third adjusting plate 83 during use. In addition, the third adjusting plate 83 can be provided with two pushing assemblies arranged in a direction perpendicular to the third adjusting plate 83, each pushing assembly includes two electric telescopic rods 84 arranged in a direction parallel to the third adjusting plate 83, the extension direction of each electric telescopic rod 84 is perpendicular to the second adjusting plate 82, and the end of each electric telescopic rod 84 away from the second adjusting plate 82 is hinged to the bearing plate 2. After the walking unit 1 moves to the vicinity of the demolding slope 92, the height position of the bearing plate 2 can be matched with the demolding slope 92 by lifting the third adjusting plate 83, and then all the electric telescopic rods 84 are driven to extend, so that the bearing plate 2 moves towards the demolding slope 92. When the bearing plate 2 is in contact with the demolding slope 92, since each electric telescopic rod 84 is hinged to the bearing plate 2, the extension and retraction of each electric telescopic rod 84 can be adjusted individually, so that the bearing plate 2 is gradually adjusted to be parallel to the demolding slope 92, facilitating subsequent polishing work.

[0028] ​Optionally, to realize the lifting action of the third adjusting plate 83, a connecting seat 85 can be arranged on the first adjusting plate 81, and a lifting electric cylinder 851 is arranged on the connecting seat 85, and the telescopic rod end of the lifting electric cylinder 851 is connected with the third adjusting plate 83. When the lifting electric cylinder 851 drives the telescopic rod to perform the telescopic action, the third adjusting plate 83 will follow the telescopic action of the telescopic rod of the lifting electric cylinder 851 to perform the lifting action. In addition, to facilitate the guidance and constraint of the lifting action of the third adjusting plate 83, a guide column 831 can be arranged on the side wall of the third adjusting plate 83 close to the second adjusting plate 82, a guide cutout 821 for accommodating the guide column 831 can be arranged on the second adjusting plate 82, and a detachable limiting plate 832 is further arranged at the end of the guide column 831 away from the third adjusting plate 83. When assembling, the staff should first insert the guide column 831 into the guide cutout 821, and then install the limiting plate 832 on the guide column 831, so that the limiting plate 832 and the third adjusting plate 83 are respectively located on both sides of the second adjusting plate 82. When the third adjusting plate 83 performs the lifting action, the cooperation of the limiting plate 832 and the third adjusting plate 83 can prevent the guide column 831 from separating from the guide cutout 821, and the cooperation of the guide cutout 821 and the guide column 831 can guide and constrain the lifting action of the third adjusting plate 83, thereby improving the action reliability of the third adjusting plate 83.

[0029] Figure 4 A structure schematic diagram of the polishing unit is shown in the figure. In the embodiment, the polishing unit comprises a pre-polishing assembly, a reinforcing polishing assembly, a supplementary polishing disc 31 and a linkage assembly. The supplementary polishing disc 31 is rotatably arranged on the bearing plate 2. The pre-polishing assembly and the reinforcing polishing assembly are both located on the side of the supplementary polishing disc 31 close to the root of the demolding slope 92. The connecting line of the pre-polishing assembly and the reinforcing polishing assembly is parallel to the advancing direction of the walking unit 1, and the pre-polishing assembly and the reinforcing polishing assembly are respectively located on both sides of the supplementary polishing disc 31. To drive the supplementary polishing disc 31, a supplementary polishing motor 32 should be arranged on the bearing plate 2. The supplementary polishing motor 32 and the supplementary polishing disc 31 should be respectively located on both sides of the bearing plate 2, and the output shaft of the supplementary polishing motor 32 is connected with the supplementary polishing disc 31. When polishing, the pre-polishing assembly and the reinforcing polishing assembly are used to polish the root of the demolding slope 92, and the supplementary polishing disc 31 is used to polish other parts of the demolding slope 92, so that the device has a good polishing range. When there is a large amount of adhesion with a large thickness at the root of the demolding slope 92, the linkage assembly can realize the cooperative action of the pre-polishing assembly and the reinforcing polishing assembly, so that the pre-polishing assembly and the reinforcing polishing assembly can perform two times of layered polishing on the adhesion, and the pre-polishing assembly can be protected to prevent damage.

[0030] Figure 5As shown in the exploded view of the pre-polishing assembly, the pre-polishing assembly comprises a guide base and a pre-polishing disc 44, wherein the guide base is provided with a first assembly hole 42, the pre-polishing disc 44 is provided with a first transmission sleeve 441 on the top surface, and the first transmission sleeve is rotatably arranged inside the first assembly hole 42. In order to realize the assembly of the pre-polishing assembly, the carrier plate 2 should be provided with a first accommodating hole 21, the guide base is arranged inside the first accommodating hole 21 in a liftable manner, and the guide base is provided with a distance sensor 43 for detecting the lifting stroke of the guide base. When the polishing process is performed, the rotation of the pre-polishing disc 44 can grind the root area of the demolding slope 92, so as to make the adhering object fall off. When the thickness of the adhering object is large, since the grinding of the thick adhering object generates a large abutting force on the pre-polishing disc 44, and the guide base has the lifting capability, the pre-polishing disc 44 will move away from the demolding slope 92 through the lifting action of the guide base. In this way, not only can the pre-polishing disc 44 be prevented from being damaged due to continuously bearing excessive grinding stress, but also the top of the adhering object can be polished after the pre-polishing disc 44 is lifted, so as to reduce the overall thickness of the adhering object, and facilitate the subsequent reinforced polishing assembly to completely remove the adhering object.

[0031] Optionally, in order to guide the lifting movement of the guide base, the pre-polishing assembly can further include a first mounting plate 45. During assembly, the first mounting plate 45 should be located above the guide base, and the first mounting plate 45 is detachably connected to the carrier plate 2 through a first guide rod 46, and a first guide hole 461 for accommodating the first guide rod 46 is arranged on the guide base. When the guide base performs the lifting action, the cooperation of the first guide rod 46 and the first guide hole 461 can guide and constrain the lifting action, so as to avoid abnormal tilting of the guide base during lifting. Secondly, in order to ensure that the pre-polishing disc 44 can continuously and reliably obtain a rotating torque when following the guide base to perform the lifting action, a pre-polishing motor 451 should be arranged on the first mounting plate 45, a first transmission key 452 is arranged on the output shaft of the pre-polishing motor 451, and a first sliding groove for accommodating the first transmission key 452 is arranged on the inner side wall of the first transmission sleeve 441. During assembly, the output shaft of the pre-polishing motor 451 is inserted into the inside of the first transmission sleeve 441, and the first transmission key 452 is slidably arranged in the first sliding groove. When the pre-polishing disc 44 follows the guide base to perform the lifting action, the first transmission key 452 will slide in the first sliding groove, and when the pre-polishing motor 451 is started, the rotating torque on the output shaft thereof will be transmitted to the first transmission sleeve 441 through the first transmission key 452 and the first sliding groove, thereby driving the pre-polishing disc 44 to rotate. In addition, in order to facilitate the guide base and the pre-polishing disc 44 to reset after leaving the thicker adherend, a reset spring 47 can also be arranged below the first mounting plate 45, one end of the reset spring 47 should be connected to the first mounting plate 45, and the other end should be connected to the guide base. When the guide base performs the lifting action, the reset spring 47 will be deformed, and after the pre-polishing disc 44 leaves the thicker adherend, the elastic force generated by the deformation of the reset spring 47 will make the guide base return to the position before contacting the thicker adherend, so as to facilitate the polishing of the subsequent adherend.

[0032] As an optional embodiment of the present embodiment, the guide base can include an upper limiting ring 411, a connecting segment 412 and a lower limiting ring 413 connected in sequence from top to bottom, wherein the outer diameter of the connecting segment 412 is equal to the inner diameter of the first accommodating hole 21, and the outer diameters of the upper limiting ring 411 and the lower limiting ring 413 are both greater than the inner diameter of the first accommodating hole 21, so as to limit the lifting stroke of the guide base by means of the upper limiting ring 411 and the lower limiting ring 413, thereby avoiding damage to the pre-polishing motor 451 or the pre-polishing disc 44 caused by the lifting of the guide base. Correspondingly, in order to facilitate the assembly between the guide base and the carrier plate 2, the connecting segment 412 and the lower limiting ring 413 can be detachably connected by means of bolt connection, so as to facilitate the assembly of the connecting segment 412 into the first accommodating hole 21 after the lower limiting ring 413 is removed.

[0033] In addition, the distance sensor 43 can be arranged on the upper limit ring 411 to facilitate detection of the lifting stroke of the guide seat. During operation, the distance sensor 43 continuously detects the distance between the upper limit ring 411 and the bearing plate 2. When the distance between the upper limit ring 411 and the bearing plate 2 increases, the distance increase is the lifting stroke of the guide seat. When the distance between the upper limit ring 411 and the bearing plate 2 decreases, the distance decrease is the lowering stroke of the guide seat.

[0034] It should be noted that the distance sensor 43 in the present embodiment is a mature ranging device in the prior art. The specific working principle, component structure, and control method of the distance sensor 43 are well known to the public and do not belong to the invention content of the present application, so they will not be described in detail herein.

[0035] Figure 6 To strengthen the exploded view of the polishing assembly, as shown, the strengthening polishing assembly includes a guide disc 51 and a strengthening polishing disc 52. The guide disc 51 is arranged on the bearing plate 2 in a lifting manner, and a second assembly hole 511 is arranged on the guide disc 51. The top surface of the strengthening polishing disc 52 is provided with a second transmission sleeve 521, and the bearing plate 2 is provided with a second accommodating hole 22 for accommodating the second transmission sleeve 521. The second transmission sleeve 521 is rotatably arranged in the second assembly hole 511. Since the connecting lines of the pre-polishing assembly and the strengthening polishing assembly are parallel to the advancing direction of the walking unit 1, when polishing, the strengthening polishing disc 52 will polish the root of the demolding slope 92 along the advancing track of the pre-polishing disc 44 for the second time to improve the polishing quality of the root of the demolding slope 92. In addition, when the pre-polishing disc 44 moves upward due to the large thickness of the attached objects, the guide disc 51 will also move downward under the action of the linkage assembly, and the strengthening polishing disc 52 will move towards the demolding slope 92, thereby improving the contact force between the strengthening polishing disc 52 and the root of the demolding slope 92, and improving the polishing effect of the strengthening polishing disc 52 on the attached objects, so as to completely remove the attached objects on the root of the demolding slope 92.

[0036] Similar to the pre-polishing assembly, in order to guide the lifting movement of the guide disc 51, the reinforcing polishing assembly can also include a second mounting plate 53. During assembly, the second mounting plate 53 is located above the guide disc 51, and the second mounting plate 53 is detachably connected to the bearing plate 2 through a second guide rod 54, and a second guide hole 541 for accommodating the second guide rod 54 is arranged on the guide disc 51. When the guide disc 51 performs the lifting action, the cooperation of the second guide rod 54 and the second guide hole 541 can guide and constrain the lifting action, so as to avoid abnormal tilting of the guide disc 51 during lifting. Correspondingly, in order to ensure that the reinforcing polishing disc 52 can continuously and reliably obtain the rotating torque when following the guide disc 51 to perform the lifting action, the second mounting plate 53 is provided with a reinforcing polishing motor 531, a second transmission key 532 is arranged on the output shaft of the reinforcing polishing motor 531, and a second sliding groove for accommodating the second transmission key 532 is arranged on the inner side wall of the second transmission sleeve 521. During assembly, the output shaft of the reinforcing polishing motor 531 should be inserted into the inside of the second transmission sleeve 521, and the second transmission key 532 should be slidably arranged in the second sliding groove. When the reinforcing polishing disc 52 follows the guide disc 51 to perform the lifting action, the second transmission key 532 will slide in the second sliding groove, and when the reinforcing polishing motor 531 is started, the rotating torque on the output shaft will be transmitted to the second transmission sleeve 521 through the second transmission key 532 and the second sliding groove, thereby driving the reinforcing polishing disc 52 to rotate.

[0037] It should be additionally pointed out that, in order to prevent the first transmission sleeve 441 and the second transmission sleeve 521 from axially moving during use, a retaining ring should be arranged on the first transmission sleeve 441 and the second transmission sleeve 521. The retaining ring should be detachably connected to the first transmission sleeve 441 and the second transmission sleeve 521, so as to facilitate the subsequent assembly of the first transmission sleeve 441 and the second transmission sleeve 521 with other components.

[0038] In actual application, due to the inevitable gap between the reinforcing polishing disc 52 and the pre-polishing disc 44, and the size difference of the adhering objects on the demolding slope 92, in order to ensure that the reinforcing polishing disc 52 still retains the contact force enhancement effect generated by the lifting action of the pre-polishing disc 44 when passing through the adhering objects, the reinforcing polishing assembly can also include a damping elastic component.

[0039] As Figure 8As shown, the damping elastic component can include a base 61, a rubber piston head 62, a contact rod 63 and a feedback spring 64. The bottom end of the base 61 is detachably connected with the bearing plate 2 by a bolt, and a containing cavity 611 is arranged inside the base 61. The rubber piston head 62 is arranged inside the containing cavity 611 in a lifting manner, and the side wall of the rubber piston head 62 is in contact with the inner wall of the containing cavity 611. The top end of the contact rod 63 is detachably connected with the guide disc 51 by a bolt, and the bottom end of the contact rod 63 is inserted into the containing cavity 611 and connected with the piston head. The feedback spring 64 is arranged inside the containing cavity 611, and one end of the feedback spring 64 is connected with the bottom surface of the rubber piston head 62, and the other end is connected with the bottom inner wall of the containing cavity 611.

[0040] When the guide disc 51 descends due to the rising of the guide seat, the rubber piston head 62 will descend synchronously inside the containing cavity 611, and the feedback spring 64 will be compressed. Since the side wall of the rubber piston head 62 is in contact with the inner wall of the containing cavity 611, the lifting and descending of the rubber piston head 62 will be delayed due to the frictional resistance, so as to form a time difference between the lifting and descending of the guide disc 51 and the lifting and descending of the guide seat, so as to ensure that the reinforced polishing disc 52 can retain the contact force enhancement effect generated by the lifting and descending of the pre-polishing disc 44 when passing through the adhering object. Correspondingly, the elastic force generated by the deformation of the feedback spring 64 can also reset the guide disc 51, so as to timely remove the contact force enhancement effect of the reinforced polishing disc 52 after completing the polishing treatment of the current adhering object, and prevent the reinforced polishing disc 52 from causing improper damage to the demolding slope 92.

[0041] In addition, in order to balance the pressure difference of the containing cavity 611 during the lifting and descending of the rubber piston head 62, the side wall and the top surface of the base 61 can be provided with a gas guide hole 612 connected with the containing cavity 611, so as to facilitate the smooth movement of the rubber piston head 62.

[0042] As Figure 7As shown, in order to realize the cooperative action of the guide disc 51 and the guide seat, the linkage assembly in the embodiment includes a support seat 23 and a linkage lever. The support seat 23 is arranged on the bearing plate 2, and the support seat 23 is located between the pre-polishing assembly and the reinforced polishing assembly. The middle part of the linkage lever is rotationally connected with the support seat 23, one end of the linkage lever is hingedly connected with the guide seat, and the other end is hingedly connected with the guide disc 51. When the guide seat performs the ascending or descending action, the rotation of the linkage lever will drive the guide disc 51 to correspondingly perform the descending or ascending movement, so that the actions of the pre-polishing disc 44 and the reinforced polishing disc 52 are associated. Correspondingly, the staff can also adjust the lengths of the linkage levers on both sides of the support seat 23 according to the actual type of the adhering objects (for example, when the adhering objects on the steel formwork have high hardness and density, the length of the linkage lever close to the pre-polishing assembly side is less than the length of the linkage lever close to the reinforced polishing assembly side through the position adjustment of the support seat 23, so that the reinforced polishing disc 52 generates a greater contact force to improve the effect when the pre-polishing disc 44 ascends a smaller amplitude), so that the action association degree of the pre-polishing disc 44 and the reinforced polishing disc 52 matches the actual demand.

[0043] In actual application process, since the pre-polishing disc 44 may vibrate during polishing the adhering objects, in order to avoid the ascending and descending actions of the pre-polishing disc 44 due to slight vibration from affecting the normal work of the reinforced polishing assembly, the linkage lever in the embodiment can include a bearing shaft 71, a response rod 72 and a trigger rod 73.

[0044] Specifically, the bearing shaft 71 is rotationally arranged on the support seat 23, the axis of the bearing shaft 71 is parallel to the bearing plate 2, and the axis of the bearing shaft 71 is perpendicular to the connecting line between the pre-polishing assembly and the reinforced polishing assembly. A transmission rod 711 is arranged on the side wall of the bearing shaft 71, and the end of the transmission rod 711 away from the bearing shaft 71 is hingedly connected with the guide disc 51. One end of the response rod 72 is hingedly connected with the guide seat, and the other end is rotationally arranged on the bearing shaft 71. The trigger rod 73 is located above the response rod 72, and the trigger rod 73 is parallel to the bearing shaft 71. The side wall of the trigger rod 73 is connected with the bearing shaft 71 through a connecting rod 731, and a trigger gap is formed between the trigger rod 73 and the response rod 72.

[0045] Since there is a trigger gap between the trigger lever 73 and the response lever 72, when the guide seat rises due to slight vibration of the pre-polishing disc 44, the response lever 72 will not contact the trigger lever 73, so that the bearing shaft 71 will not rotate, and the guide disc 51 will not descend due to the rising of the guide seat. When the rising of the guide seat is sufficient to make the response lever 72 contact the trigger lever 73 and drive the bearing shaft 71 to rotate, it proves that the pre-polishing disc 44 has contacted the thick adherent, and the rotation of the bearing shaft 71 will be transmitted to the inside of the guide disc 51 through the transmission lever 711, so as to make the guide disc 51 descend and increase the contact force between the reinforced polishing disc 52 and the demolding slope 92.

[0046] In addition, in order to realize the articulation between the linkage lever, the guide disc 51 and the guide seat, and avoid the action dead point of the linkage lever in use, the side wall of the guide disc 51 and the side wall of the guide seat can be provided with an articulation shaft, and the response lever 72 and the transmission lever 711 are respectively provided with an oblong hole for accommodating the articulation shaft.

[0047] As another optional embodiment of the present embodiment, in order to ensure that the polishing unit has a good polishing processing range, the diameter of the pre-polishing disc 44 should be equal to the diameter of the reinforced polishing disc 52, the diameter of the supplementary polishing disc 31 should be greater than the diameter of the reinforced polishing disc 52, and the shortest distance between the center of the supplementary polishing disc 31 to the center of the pre-polishing disc 44 and the center of the reinforced polishing disc 52 should be less than the radius of the supplementary polishing disc 31. In this way, the polishing ranges of the pre-polishing disc 44, the supplementary polishing disc 31 and the reinforced polishing disc 52 will form an intersection, so as to avoid the dead angle of polishing processing on the demolding slope 92 passed by the polishing unit. In addition, the bottom edge of the pre-polishing disc 44 can be provided with a guide arc surface 442, so as to reduce the difficulty of the rising action of the pre-polishing disc 44 through the guide arc surface 442, and further improve the protection effect of the pre-polishing disc 44.

[0048] On the basis of the above, the present embodiment further provides a steel formwork demolding slope polishing processing method, which is realized by using the steel formwork demolding slope polishing processing device.

[0049] Figure 9 The flow chart of the steel formwork demolding slope polishing processing method is shown in the figure, and the steel formwork demolding slope polishing processing method specifically includes the following steps: Step S1, after the walking unit 1 moves to the vicinity of the demolding slope 92, the advancing direction of the walking unit 1 is adjusted according to the intersection line between the demolding slope 92 and the steel formwork body 91, so that the advancing direction of the walking unit 1 is parallel to the intersection line between the demolding slope 92 and the steel formwork body 91.

[0050] Generally, the staff will set the trajectory of the walking unit 1 according to the actual situation of the steel template to be processed, so that the walking unit 1 can pass through each demolding slope 92 to be processed in turn. However, due to the difference in direction and position of different demolding slopes 92, when the walking unit 1 moves to a certain demolding slope 92, the direction of the walking unit 1 needs to be adjusted according to the intersection line between the demolding slope 92 and the steel template body 91, so that the direction of the walking unit 1 is parallel to the intersection line between the demolding slope 92 and the steel template body 91, ensuring that the adjustment unit and the polishing unit carried on the walking unit 1 can pass through the entire demolding slope 92 during polishing.

[0051] It should be noted that when identifying the intersection line between the demolding slope 92 and the steel template body 91, existing technologies such as binocular recognition can be used for identification and judgment, and the current direction of the walking unit 1 can be determined by combining the gyroscope and various sensors in the common walking unit 1, so that the direction of the walking unit 1 is parallel to the intersection line between the demolding slope 92 and the steel template body 91.

[0052] Step S2, adjust the attitude of the bearing plate 2 by the adjustment unit, so that the bearing plate 2 is parallel to the demolding slope 92, and the bottom surface of the supplementary polishing disc 31, the bottom surface of the pre-polishing disc 44 and the bottom surface of the reinforced polishing disc 52 in the polishing unit are all in contact with the demolding slope 92, and the edge of the bottom surface of the reinforced polishing disc 52 is in contact with the intersection line between the demolding slope 92 and the steel template body 91.

[0053] When adjusting the attitude, the bearing plate 2 should be brought into a parallel attitude with the demolding slope 92 by the adjustment unit first, and the bottom surface of the supplementary polishing disc 31, the bottom surface of the pre-polishing disc 44 and the bottom surface of the reinforced polishing disc 52 in the polishing unit should all be in contact with the demolding slope 92, and then the edge of the bottom surface of the reinforced polishing disc 52 should be in contact with the intersection line between the demolding slope 92 and the steel template body 91, so as to avoid collision and damage between the polishing discs in the polishing unit and the demolding slope 92.

[0054] Step S3, start the polishing unit to make the supplementary polishing disc 31, the pre-polishing disc 44 and the reinforced polishing disc 52 start rotating, so as to polish the demolding slope 92; wherein the pre-polishing disc 44 and the reinforced polishing disc 52 are used to polish the root of the demolding slope 92, and the supplementary polishing disc 31 is used to polish other parts of the demolding slope 92.

[0055] Step S4, the lifting stroke of the guide seat is determined by the distance sensor 43, when the lifting stroke of the guide seat is greater than the preset stroke threshold, the rotation speed of the reinforced polishing disc 52 is increased and the advancing speed of the walking unit 1 is reduced, and the increase amplitude of the rotation speed of the reinforced polishing disc 52 and the reduction amplitude of the advancing speed of the walking unit 1 are both proportional to the size of the lifting stroke of the guide seat.

[0056] When the lifting stroke of the guide seat is greater than the preset stroke threshold, it proves that the thickness of the current attachment is too large, so as to ensure that the current attachment obtains good polishing processing effect, the embodiment will increase the grinding capacity of the reinforced polishing disc 52 by increasing the rotation speed of the reinforced polishing disc 52, and prolong the grinding time of the reinforced polishing disc 52 by reducing the advancing speed of the walking unit 1, so as to completely remove the attachment.

[0057] Step S5, the stroke length of the walking unit 1 in the polishing process is obtained, when the stroke length is greater than the intersection length between the demolding slope 92 and the steel mold plate body 91, the polishing unit is closed and the carrying plate 2 is reset by the adjusting unit.

[0058] When the stroke length of the walking unit 1 in the polishing process is greater than the intersection length between the demolding slope 92 and the steel mold plate body 91, it proves that the current demolding slope 92 has completed polishing, at this time the polishing unit can be closed and the carrying plate 2 is reset by the adjusting unit, so as to avoid the influence of the running vibration of the motor in the polishing unit on the subsequent advancing stability of the walking unit 1, and prevent the carrying plate 2 and the polishing unit from colliding with other obstacles in the subsequent advancing process of the walking unit 1.

[0059] The effects of the above scheme are described as follows: The embodiment provides a steel mold plate demolding slope polishing processing device and method, wherein the device can continuously polish the root of the demolding slope twice, thereby improving polishing quality. When the root of the demolding slope has relatively thick attachments, the pre-polishing disc can perform lifting action, thereby protecting the pre-polishing disc and reducing the thickness of the attachments through the pre-polishing disc, and the reinforced polishing disc can be lowered under the action of the linkage assembly, thereby improving the contact force between the reinforced polishing disc and the demolding slope, and further improving the attachment polishing effect. In addition, in the method provided by the embodiment, the rotation speed of the reinforced polishing disc and the advancing speed of the walking unit can be correspondingly adjusted according to the lifting stroke of the guide seat, thereby further improving the polishing processing effect on the demolding slope.

[0060] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
