Description

Technical Field

[0001] The invention relates to the technical field of roller grinding, in particular to an outer surface sizing and grinding device used in a roller bracket. Background Art

[0002] Roller is an important tool for rolling metal materials and is widely used in metallurgy, machinery manufacturing, building materials and other industries. It is usually made of high-strength alloy steel or cast iron and has the characteristics of high temperature resistance and wear resistance. The function of the roller is to deform the metal billet through a series of rollers to change the shape and size of the metal billet, thereby obtaining the required product. Rollers can be designed into different shapes and sizes according to different rolling processes and product requirements. Rollers are generally made into blanks by casting or forging. After rough processing, the surface of the blank needs to be polished to ensure that the roughness of the roller surface meets the standard.

[0003] For example, a grinding device for sizing roller processing disclosed in the prior art with publication number CN211916303U can achieve the effect of rapid clamping and grinding of the sizing roller. However, in the actual grinding process, the fixed grinding plate makes it difficult to achieve comprehensive grinding of the longer rollers, requiring multiple clamping operations, resulting in low processing efficiency. In addition, it is not convenient to centrally collect the large amount of debris generated during the grinding process.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0032] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-Figure 5 and Figure 8As shown in the figure, it is difficult to achieve comprehensive grinding of longer rollers, and multiple clamping operations are required, resulting in low processing efficiency. This problem can be solved by the following solutions:

[0034] In this embodiment, an outer surface sizing and grinding device for a roller bracket includes a bracket body 1, a fixed seat 11 is fixedly connected to one side of the top of the bracket body 1, and a clamping chuck 12 and a control panel 13 are fixedly mounted on both sides of the fixed seat 11, a movable seat 14 is movably mounted on the other side of the top of the bracket body 1, and a top 15 that cooperates with the clamping chuck 12 is fixedly connected to one side of the movable seat 14, a mounting plate 16 is fixedly connected to the top of the bracket body 1, and a moving component 2 is provided on the mounting plate 16;

[0035] The roller is clamped and fixed by the tip 15 provided on the movable seat 14 and the clamping chuck 12 provided on the fixed seat 11, and the roller diameter on one side of the roller is clamped by the clamping chuck 12, thereby improving the fixing effect during the grinding process. The tip 15 provided can provide a placement area for the moving component 2 when loading and unloading the roller, so that the roller does not need to be installed with the moving component 2, thereby achieving convenience in the loading and unloading process.

[0036] The movable assembly 2 includes a movable base 21 movably mounted on the mounting plate 16, and a mounting plate 1 23 and a mounting plate 2 24 are fixedly connected to the movable base 21 via a bracket 22. The mounting plate 1 23 and the mounting plate 2 24 are rotatably connected to a rotating sleeve 25. The rotating sleeve 25 is provided with multiple groups of grinding assemblies 3 distributed in a circular array. The grinding assembly 3 includes a T-block 31 mounted on the rotating sleeve 25, and a grinding block 33 is fixedly mounted on the T-block 31 via an electric push rod 32. A debris collection assembly 4 is provided on the movable base 21;

[0037] After the roller is placed between the clamping chuck 12 and the top 15 and is clamped and fixed, the electric push rod 32 is operated through the control panel 13 to drive the grinding block 33 to fit the annular outer surface of the roller, and then the grinding block 33 is driven to rotate circumferentially through the rotating sleeve 25 to grind the annular outer surface of the roller. The electric push rod 32 is controlled through the control panel 13 to drive the moving distance of the grinding block 33 to complete the purpose of roller sizing grinding.

[0038] The bracket body 1 is fixedly connected to two sets of slide rails 17 that are slidably connected to the movable seat 14, which are used to improve the stable sliding of the movable seat 14. The movable seat 14 is bolted with a driving block 18. The bracket body 1 is rotatably connected to a clamping screw 19 that is threadedly connected to the driving block 18, and a clamping motor 110 for driving the clamping screw 19 to rotate is bolted to the bracket body 1. One end of the roller is positioned and clamped by the clamping chuck 12, and then the clamping motor 110 is operated by the control panel 13 to drive the clamping screw 19 to rotate. The clamping screw 19, in combination with the driving block 18, drives the movable seat 14 to move, so that the top 15 contacts the center of the other end of the roller, thereby completing the fixation of the roller.

[0039] During the process of clamping and fixing the rolling roller, the position of the movable seat 21 is adjusted synchronously to avoid interference of the movable seat 21 with the movement of the movable seat 14, or the top 15 is installed on the fixed seat 11 and the clamping chuck 12 is installed on the movable seat 14. This can avoid adjusting the position of the movable seat 14 while synchronously adjusting the position of the movable seat 21, thereby improving the convenience of the clamping process.

[0040] Two groups of slide rails 111 slidably connected to the moving seat 21 are fixedly connected to the mounting plate 16, which are used to improve the stable sliding of the moving seat 21. The moving seat 21 is bolted with a driving block 26. A moving screw rod 112 threadedly connected to the driving block 26 is rotatably connected to the mounting plate 16, and a moving motor 113 for driving the moving screw rod 112 to rotate is bolted on the mounting plate 16. The moving motor 113 is operated by the control panel 13 to drive the moving screw rod 112 to rotate. The moving screw rod 112 is combined with the driving block 26 to drive the moving seat 21 to move, so that the rotating sleeve 25 moves from the outside of the top 15 to the outside of the roller, and performs reciprocating linear motion, and cooperates with the grinding component 3 to realize comprehensive grinding of the roller surface.

[0041] An outer gear ring 27 is fixedly connected to the annular outer wall of the rotating sleeve 25, a grinding motor 28 is bolted to the mounting plate 1 23, and a gear 29 meshing with the outer gear ring 27 is fixedly connected to the output shaft of the grinding motor 28. The grinding motor 28 is operated by the control panel 13 to drive the gear 29 to rotate. The gear 29 drives the rotating sleeve 25 to rotate through the meshing outer gear ring 27, thereby driving the multiple grinding blocks 33 to rotate circumferentially, and combined with the electric push rod 32 to perform sizing grinding on the annular outer surface of the roller. A telescopic sleeve rod 34 is symmetrically fixedly connected between the T-block 31 and the grinding block 33. The provided telescopic sleeve rod 34 is used to increase the connection stability between the grinding block 33 and the T-block 31, thereby achieving a stable grinding effect.

[0042] The rotating sleeve 25 is provided with a movable groove 210 that is slidably connected to the corresponding T-block 31, providing space for the sliding of the T-block 31. An arc-shaped limit baffle 35 is fixedly connected to one side of the T-block 31 on the grinding block 33. The arc-shaped limit baffle 35 is used for the sliding installation of the T-block 31 on the rotating sleeve 25 on the one hand, and for blocking the movable groove 210 on the other hand to prevent the generated debris from flying around, which makes it difficult to collect and clean;

[0043] The two sides of the T-block 31 are symmetrically fixedly connected with guide rods 36, and the opposite sides of the mounting plate 1 23 and the mounting plate 2 24 are provided with an annular wave groove 211 that is in sliding contact with the end of the corresponding guide rod 36. When the grinding block 33 rotates circumferentially, the annular wave groove 211 on the mounting plate 1 23 and the mounting plate 2 24 contacts the corresponding guide rod 36, forcing the T-block 31 to carry the grinding block 33 to perform synchronous reciprocating linear motion, thereby increasing the number of contacts between the grinding block 33 and each area of ​​the roller, thereby greatly improving the sizing grinding efficiency of the roller.

[0044] Example 2: Please refer to Figure 2-Figure 7 As shown, the problem of inconvenience in collecting a large amount of debris generated during the grinding process and causing inconvenience in cleaning the debris can be solved by the following solution:

[0045] In this embodiment, the debris collection assembly 4 includes a collection box 41 fixedly connected to the movable seat 21, and a debris suction pipe 42 is fixedly connected between the collection box 41 and the mounting plate 1 23. The air in the rotating sleeve 25 is extracted through the provided debris suction pipe 42, and the flowing air will carry fine particles of debris and move synchronously, so that the debris is collected in the collection box 41. An annular diverter pipe 43 is fixedly connected to the mounting plate 24 and located inside the rotating sleeve 25, and the annular diverter pipe 43 is densely covered with air outlet holes 44. An air outlet pipe 45 is fixedly connected between the annular diverter pipe 43 and the collection box 41, and an air suction fan 46 is installed on the air outlet pipe 45;

[0046] During the process of grinding the roller by the grinding block 33, the suction fan 46 draws the air in the collection box 41 to form a negative pressure environment in the collection box 41, and then draws the air containing debris in the rotating sleeve 25 through the chip suction pipe 42, and the filter 47 placed in the collection box 41 is used to absorb and intercept the generated debris in the collection box 41 for collection. The absorbed and filtered gas is injected into the annular diversion pipe 43 through the outlet pipe 45, and then blown to the surface of the roller through multiple air outlet holes 44, cooling the grinding area of ​​the roller, thereby extending the service life of the grinding block 33 and avoiding the problem of large amounts of heat generated by the roller during the grinding process, which may easily cause damage to the roller.

[0047] A filter 47 is fixedly installed inside the collection box 41. A serpentine cooling pipe 48 is fixedly installed inside the collection box 41 and located between the filter 47 and the air outlet pipe 45. A plurality of fins 49 are fixedly connected to the serpentine cooling pipe 48. A plurality of oblique chip removal grooves 37 are formed on the side of the grinding block 33 away from the T-block 31.

[0048] During the rapid reciprocating linear motion of the T-shaped block 31 carrying the grinding block 33, the oblique chip removal groove 37 provided on the grinding block 33 can effectively guide the chips to be quickly discharged from the contact surface between the grinding block 33 and the roller, thereby avoiding the problem of reduced grinding efficiency and damage to the roller surface caused by the accumulation of chips, thereby improving the grinding and polishing effect. In addition, part of the filtered air will be blown into the oblique chip removal groove 37 on the grinding block 33, thereby further accelerating the discharge and collection of chips, and at the same time increasing the cooling effect on the grinding block 33 and the roller;

[0049] Before being discharged from the collecting box 41, the filtered air is connected to the serpentine cooling pipe 48 through an external cooling device, and the filtered hot air is cooled in combination with the fins 49, thereby enhancing the cooling effect on the rollers.

[0050] A fixing plate 212 is bolted to the opposite sides of the mounting plate 1 23 and the mounting plate 2 24, and a cleaning brush ring 213 is fixedly connected to the middle of the fixing plate 212. By installing the fixing plate 212 with the cleaning brush ring 213 on the mounting plate 1 23 and the mounting plate 2 24, not only can the debris be effectively blocked from being blown out from the inside of the rotating sleeve 25, but the surface of the roller after grinding can also be cleaned, thereby improving the cleaning and collection effect of the debris, and the cleaning brush ring 213 can also be replaced with a blocking ring adapted to the diameter of the roller to further increase the effect of preventing the debris from being blown out, and by detachably connecting the fixing plate 212, the cleaning brush ring 213 of the adapted diameter can be replaced according to the diameter of the roller, thereby further improving the effect of preventing the debris from flying around for rollers of different sizes.

[0051] Example 3: Please refer to Figures 1-8 As shown, the present invention also provides a method for using the outer surface sizing and grinding device for a roller bracket, comprising the following steps:

[0052] Step 1: Place the roll between the clamping chuck 12 and the top 15, and operate the clamping motor 110 through the control panel 13 to drive the clamping screw 19 to rotate. The clamping screw 19, in conjunction with the driving block 18, drives the movable seat 14 to move, so that the top 15 contacts the center of one end of the roll, and in conjunction with the clamping chuck 12, positions and clamps the other end of the roll;

[0053] Step 2: Operate the moving motor 113 through the control panel 13 to drive the moving screw 112 to rotate. The moving screw 112, in conjunction with the second driving block 26, drives the moving seat 21 to move, so that the rotating sleeve 25 moves from the outside of the top 15 to the outside of the roller, and performs reciprocating linear motion;

[0054] Step 3: Operate the electric push rod 32 through the control panel 13 to drive the grinding block 33 to fit the annular outer surface of the roller, then operate the grinding motor 28 to drive the rotating sleeve 25 to rotate through the meshing gear 29 and the outer gear ring 27, and the rotating sleeve 25 drives the grinding block 33 to rotate circumferentially to grind the annular outer surface of the roller, and control the electric push rod 32 through the control panel 13 to drive the moving distance of the grinding block 33 to complete the purpose of roller sizing grinding;

[0055] Step 4: As the grinding block 33 rotates circumferentially, the annular wave grooves 211 on the mounting plates 1 23 and 24 contact the corresponding guide rods 36, forcing the T-shaped block 31 to carry the grinding block 33 in synchronous reciprocating linear motion, thereby increasing the number of contacts between the grinding block 33 and various areas of the roller, thereby improving the grinding efficiency;

[0056] Step 5: When the grinding block 33 is grinding the roller, the generated debris is quickly discharged from between the grinding block 33 and the roller through the multiple oblique chip removal grooves 37. At the same time, the suction fan 46 extracts air from the rotating sleeve 25 through the collection box 41 and the chip suction pipe 42, and combines with the filter 47 to absorb the generated debris and intercept it in the collection box 41 for collection. The absorbed and filtered air is injected into the annular diverter pipe 43 through the air outlet pipe 45, and then blown to the roller surface through the multiple air outlet holes 44, cooling the grinding area of ​​the roller. Part of the filtered air will be blown into the oblique chip removal grooves 37 on the grinding block 33, thereby further accelerating the discharge and collection of debris.

[0057] Step 6: During the process of collecting the debris, the serpentine cooling pipe 48 is connected through an external cooling device, and the filtered air is cooled in combination with the fins 49, thereby accelerating the cooling effect of the roller.

[0058] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
