Description

Technical Field

[0001] This utility model belongs to the field of cold rolling process technology, and specifically relates to a quick-release scraper assembly for cold rolling rolls. Background Technology

[0002] Rolls are key components that directly contact the workpiece during the rolling process and cause it to undergo plastic deformation. They are widely used in metal rolling (including hot rolling in addition to cold rolling) and non-metal rolling. Cold rolling rolls operate at lower temperatures and mainly bear high rolling forces and friction, requiring higher surface hardness, wear resistance, and precision. The working part of the roll directly contacts and deforms the workpiece, so its surface must have high hardness and wear resistance. The roll neck is located at both ends of the roll body and is used to support the roll and mount it on the bearing housing of the rolling mill. It must have sufficient strength and toughness. The part outside the roll head and roll neck is used to connect with the transmission device of the rolling mill (such as gears and couplings) to transmit rolling torque and must have good transmission performance.

[0003] Specifically, during the cold rolling process, various impurities such as iron filings, oil stains, and oxide scale inevitably adhere to the surface of the rolls. If these impurities are not removed in time, they will not only scratch the surface of the rolled product and affect its precision, but may also accelerate roll wear and shorten its service life. In traditional processes, scraper assemblies are usually used to clean impurities from the roll surface. However, traditional scrapers are mostly fixed to the mounting frame by bolts, nuts, and other fasteners through a "locking and tightening" method. This fixing method has obvious drawbacks: when it is necessary to replace worn scrapers or maintain the assembly, operators need to use tools such as wrenches to disassemble the fasteners one by one. This is not only cumbersome and time-consuming, but may also cause the fasteners to rust and strip due to long-term use, further increasing the difficulty of disassembly and assembly. More importantly, if the fasteners are subjected to uneven force during frequent disassembly and assembly, it may cause the scraper installation position to deviate, affecting its contact accuracy with the roll surface, thereby reducing the impurity cleaning effect and indirectly adversely affecting the surface quality and production efficiency of cold-rolled products.

[0004] The purpose of this invention is to provide a quick-release scraper assembly for cold rolling rolls, aiming to solve the problem that traditional scrapers rely on bolts, nuts, and other fasteners to be fixed to the mounting frame through a "locking and tightening" method. This fixing method has obvious drawbacks: when it is necessary to replace worn scrapers or maintain the assembly, operators need to use tools such as wrenches to disassemble the fasteners one by one. This is not only cumbersome and time-consuming, but also may cause the fasteners to rust and strip due to long-term use, further increasing the difficulty of disassembly and assembly; more importantly, if the fasteners are subjected to uneven force during frequent disassembly and assembly, it may cause the scraper installation position to deviate, affecting its contact accuracy with the roll surface, thereby reducing the impurity cleaning effect and indirectly adversely affecting the surface quality and production efficiency of cold-rolled products.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-release scraper assembly for a cold rolling roll, comprising a support side plate and a cold rolling roll installed inside the support side plate, wherein a support plate is connected to the top surface of the support side plate, and a crossbeam plate is connected to the top of the support plate.

This allows for the cleaning of iron filings, oil stains, oxide scale, and other impurities adhering to the blade plate and cold rolling roll. When the scraper needs to be disassembled for maintenance, pulling the disassembly rod at one end of the docking seat causes the positioning plate to compress the positioning spring. This causes the locking plate to be removed from the docking groove at one end of the docking plate. Simultaneously, the positioning groove on the surface of the locking plate slides along the positioning block, allowing the docking plates at both ends of the scraper to quickly disengage from the docking seat. This facilitates the rapid removal of the scraper and improves the effectiveness of subsequent scraper maintenance. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4The present invention provides the following technical solution: a quick-release scraper assembly for a cold rolling roll, comprising a support side plate 1 and a cold rolling roll 2 installed inside the support side plate 1. The cold rolling roll 2 is used to connect with the transmission device of the rolling mill (such as gears or couplings) to transmit rolling torque and must have good transmission performance. A support plate 3 is connected to the top surface of the support side plate 1, and a crossbeam plate 4 is connected to the top of the support plate 3.

[0023] A blade 5 is connected to the inner side of the support plate 3. A scraper 6 is connected to the bottom surface of the blade 5. Both ends of the scraper 6 are connected to a mating plate 7. A mating seat 8 is connected to the bottom surface of the blade 5 near the mating plate 7. A disassembly rod 9 is connected to the opening at one end of the mating seat 8. A positioning plate 10 is connected to the other end of the disassembly rod 9. A positioning spring 11 is connected to one side of the positioning plate 10. A locking insert 12 is connected to the other side of the positioning plate 10. A positioning block 13 is connected to the top of the inner wall of the mating seat 8.

[0024] Preferably, the docking seat 8 has a docking groove on the side near the docking plate 7, and the scraper 6 is fitted and connected to the docking groove on one side of the docking seat 8 through the docking plate 7. In actual use, by connecting the docking plates 7 at both ends of the scraper 6 to the docking seat 8, it is convenient to drive the scraper 6 to be assembled and docked.

[0025] Preferably, one end of the positioning spring 11 relative to the positioning plate 10 is connected to the inner wall of the docking seat 8, and the positioning spring 11 and the positioning plate 10 form an elastic telescopic structure. In actual use, by pulling the disassembly and assembly lever 9 on the surface of the docking seat 8, the positioning plate 10 is driven to squeeze the positioning spring 11. At this time, the elastic force of the positioning spring 11 itself facilitates the automatic insertion of the locking plate 12.

[0026] Preferably, the mating plate 7 has a slot at one end near the locking plate 12, and the locking plate 12 and the slot at one end of the mating plate 7 form a fitting structure. In actual use, by fitting the locking plate 12 into the mating groove at one end of the mating plate 7, a stable locking effect on the scraper 6 is ensured, thereby ensuring the scraper 6 can effectively remove impurities from the surface of the cold rolling roll 2.

[0027] Preferably, the locking insert 12 has a positioning groove on its surface near the positioning block 13, and the positioning block 13 and the positioning groove on the surface of the locking insert 12 form a limiting and guiding structure. In actual use, when the locking insert 12 is removed from the docking groove at one end of the docking plate 7, the positioning block 13 always slides along the positioning groove on the surface of the locking insert 12, ensuring the stability of the movement of the locking insert 12 inside the docking seat 8 and avoiding the effect of the locking insert 12 shifting.

[0028] Preferably, a push cylinder 14 is connected to the surface of the crossbeam plate 4. The output end of the push cylinder 14 passes through the crossbeam plate 4 and connects to the surface of the blade plate 5. The push cylinder 14 is electrically connected to the power supply of the equipment. In actual use, the push cylinder 14 controls the up and down movement of the blade plate 5, thereby improving the specific spacing accuracy between the scraper 6 on the bottom surface of the blade plate 5 and the cold rolling roll 2, ensuring a complete cleaning effect on the surface of the cold rolling roll 2, and improving the degree of automation of the removal process.

[0029] Preferably, both ends of the blade 5 are connected to sliding blocks 15, and guide rods 16 are connected through the surface of the sliding blocks 15. Both ends of the guide rods 16 are installed on the inner wall of the support plate 3. The sliding blocks 15 form a sliding connection structure along the opening on one side of the support plate 3 through the guide rods 16. In actual use, by sliding the sliding blocks 15 along the guide rods 16, the sliding blocks 15 are ensured to move stably up and down along the opening on the inner side of the support plate 3, while ensuring the movement stability of the scraper 6 on the bottom surface of the blade 5.

[0030] The working principle of this utility model is as follows: By installing the scraper 6 on the bottom surface of the blade plate 5, the attached iron filings, oil stains, oxide scale, and other impurities on the blade plate 5 and the cold rolling roll 2 are cleaned. If the scraper 6 needs to be disassembled for maintenance, the disassembly and assembly lever 9 at one end of the docking seat 8 is pulled, which causes the positioning plate 10 to compress the positioning spring 11. At this time, the locking insert plate 12 is removed from the docking groove at one end of the docking plate 7, and the positioning groove on the surface of the locking insert plate 12 slides along the positioning block 13, so that the docking plates 7 at both ends of the scraper 6 are inside the docking seat 8. The quick release from the fixed position facilitates the rapid removal of the scraper 6, improving the efficiency of subsequent maintenance. Additionally, activating the push cylinder 14 causes the blade 5 to slide inside the support plate 3, simultaneously causing the sliding blocks 15 at both ends of the blade 5 to slide along the openings inside the support plate 3. This facilitates the sliding of the openings on the surface of the sliding blocks 15 along the guide rod 16, allowing the scraper 6 on the bottom surface of the blade 5 to be adjusted along the cold rolling roller 2. This facilitates adjusting the distance between the cold rolling roller 2 and the scraper 6, improving the scraper 6's effectiveness in cleaning different impurities.
