Description

Technical Field

[0001] This utility model belongs to the field of tool steel processing technology, and in particular relates to a tool steel strip surface grinding device. Background Technology

[0002] Tool steel, as a fundamental material in machinery manufacturing and mold processing, directly affects the precision and service life of workpieces due to its surface quality. Steel strips are prone to defects such as oxide scale and microcracks during rolling and heat treatment, requiring surface grinding processes to achieve high-precision surface finish.

[0003] However, existing grinding equipment generally suffers from two major drawbacks: First, the grinding depth adjustment mechanism mostly relies on manual operation, resulting in low adjustment accuracy and difficulty in maintaining processing consistency. Furthermore, many employ a screw-driven structure to directly push the grinding wheel, leading to large mechanical clearances and low displacement resolution, making it difficult to achieve high-precision thickness adjustment. Second, the grinding dust collection system has poor sealing; traditional fixed dust covers cannot accommodate steel strips of varying thicknesses, causing a large amount of metal dust to escape, severely polluting the workshop environment and endangering the health of operators. For example, some equipment uses fixed-gap dust baffles, which easily create gaps when the steel strip thickness changes, resulting in significant dust escape problems.

[0004] To address these issues, we provide a tool steel strip surface grinding device. Utility Model Content

[0005] The purpose of this invention is to provide a tool steel strip surface grinding device. By coordinating the adjustment components and the grinding motor, it solves the problems of high adjustment precision and lack of dustproof function in existing tool steel strip surface grinding devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a tool steel strip surface grinding device, comprising a support base, a protective box fixedly connected to the front of the support base, and a hinged flip door on the front of the protective box; an adjustment assembly is provided in the inner cavity of the protective box, the adjustment assembly including a grinding motor disposed in the inner cavity of the protective box, a grinding roller fixedly connected to the output shaft surface of the grinding motor, a fixed cylinder movably connected to the surface of the grinding roller through a bearing seat, and a drive frame slidably connected to the surface of the fixed cylinder; the inner cavity of the protective box is also provided with a dustproof assembly, the dustproof assembly including a telescopic rod fixedly connected to the inner cavity of the protective box, a baffle plate fixedly connected to the extension end of the telescopic rod, a fan fixedly connected to one side of the protective box, a filter box connected to the air inlet of the fan through a pipe, and a dust suction chamber connected to one side of the filter box through a pipe.

[0008] The present invention is further configured such that a servo motor is fixedly connected to the inner cavity of the protective box, a threaded rod is fixedly connected to the output shaft of the servo motor, a threaded sleeve is threadedly connected to the surface of the threaded rod, and a mounting plate is movably connected to the other end of the threaded rod through a bearing seat. The mounting plate is fixedly connected to the inner cavity of the protective box. When the servo motor drives the threaded rod to rotate, the threaded sleeve moves axially, driving the drive frame to move up and down.

[0009] The present invention is further configured such that a guide block is fixedly connected to the back of the grinding motor, and a sliding frame is slidably connected to the surface of both the fixed cylinder and the guide block.

[0010] The present invention is further configured such that the sliding frame is designed in an inclined shape, one side of the sliding frame is fixedly connected to the inner cavity of the protective box through the mounting block, the guide block is vertically welded to the back of the grinding motor housing, and together with the top of the fixed cylinder, two sets of V-shaped sliding frames pass through. The sliding frame is fixed to the side wall of the box with a set inclination angle. When the drive frame moves up and down, it pushes the fixed cylinder to move along the inclined track of the sliding frame, converting the vertical displacement into the horizontal displacement, thereby realizing high-precision adjustment of the grinding roller.

[0011] The present invention is further configured such that a spring is sleeved on the surface of the telescopic rod, one end of the spring is fixedly connected to one side of the shield, and the other end of the spring is fixedly connected to the inner cavity of the protective box.

[0012] The present invention is further configured such that a groove is provided on one side of the baffle plate, and a fixed roller is movably connected to the inner cavity of the groove through a rotating shaft. A telescopic rod is vertically installed on one side of the inlet and outlet. Under normal conditions, the spring pushes the baffle plate to move inward. The surface of the fixed roller embedded in the groove is covered with a silicone layer, forming a rolling seal with the steel strip. When steel strips of different thicknesses pass through, the spring compresses adaptively to maintain the airtightness of the protective box.

[0013] The present invention is further configured such that a material roller is provided on the right side of the front of the support base, and a guide roller is provided on the left side of the front of the support base. There are two material rollers, one is an unwinding roller and the other is a winding roller, so as to realize the function of rapid processing of steel strip.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a servo motor to drive the threaded rod and threaded sleeve transmission mechanism, combined with the displacement conversion characteristics of the inclined sliding frame, to convert the vertical motion of the drive frame into the horizontal micro-displacement of the grinding roller, thereby achieving precise control of the grinding depth. The constraint system formed by the guide block and the double sliding frame effectively eliminates mechanical gaps and ensures uniform and stable grinding pressure, making it suitable for precision machining of tool steel strips.

[0016] 2. This utility model enables the baffle plate to have an adaptive pressing function through the linkage mechanism of spring and telescopic rod. The silicone-coated fixing roller in the groove forms a rolling seal with the steel belt. Combined with the negative pressure dust collection duct and filtration system, it improves the dust collection efficiency.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] Please see Figures 1-5This utility model is a tool steel strip surface grinding device, including a support base 1, a protective box 2 fixedly connected to the front of the support base 1, and a flip door 3 hinged to the front of the protective box 2; the inner cavity of the protective box 2 is provided with an adjustment component, which includes a grinding motor 4 disposed in the inner cavity of the protective box 2, a grinding roller 5 fixedly connected to the output shaft surface of the grinding motor 4, a fixed cylinder 6 movably connected to the surface of the grinding roller 5 through a bearing seat, and a drive frame 7 slidably connected to the surface of the fixed cylinder 6; the inner cavity of the protective box 2 is also provided with a dustproof component, which includes a telescopic rod 8 fixedly connected to the inner cavity of the protective box 2, a baffle plate 9 fixedly connected to the extension end of the telescopic rod 8, a fan 10 fixedly connected to one side of the protective box 2, a filter box 11 connected to the air inlet of the fan 10 through a pipe, and a dust suction chamber 12 connected to one side of the filter box 11 through a pipe.

[0028] Further details: The protective box 2 has a hinged flip door 3 on the front, forming a sealed cavity that protects the grinding mechanism and prevents dust from splashing. The protective box 2 has an inlet and an outlet at the top and bottom. The steel strip is guided into the box by the material roller 21 on the right side and the guide roller 22. The fixed cylinder 6, which is movably connected to the surface of the grinding roller 5, ensures that the drive frame 7 drives the fixed cylinder 6 to slide in the inner cavity of the sliding frame 17 without affecting the rotation of the grinding roller 5, thus ensuring the continuity of the grinding process. The filter box 11 is equipped with a filter box 11 in the inner cavity to facilitate the collection and interception of dust and debris. The grinding motor 4 is slidably connected to the sliding frame 17, and the output shaft of the grinding motor 4 is constrained by the guide block 16 during rotation to prevent the grinding motor 4 from rotating on its own. The dust suction chamber 12 is located below the grinding roller 5.

[0029] Example 2

[0030] Please see Figures 1-5 Based on embodiment 1, a servo motor 13 is fixedly connected to the inner cavity of the protective box 2. A threaded rod 14 is fixedly connected to the output shaft of the servo motor 13. A threaded sleeve 15 is threadedly connected to the surface of the threaded rod 14. A guide block 16 is fixedly connected to the back of the grinding motor 4. A sliding frame 17 is slidably connected to the surface of both the fixed cylinder 6 and the guide block 16. The sliding frame 17 is designed in an inclined shape. One side of the sliding frame 17 is fixedly connected to the inner cavity of the protective box 2 through an installation block. A spring 18 is sleeved on the surface of the telescopic rod 8. One end of the spring 18 is fixedly connected to one side of the baffle plate 9. The other end of the spring 18 is fixedly connected to the inner cavity of the protective box 2. A groove 19 is opened on one side of the baffle plate 9. A fixed roller 20 is movably connected to the inner cavity of the groove 19 through a rotating shaft. A material roller 21 is provided on the right side of the front of the support base 1. A guide roller 22 is provided on the left side of the front of the support base 1.

[0031] Further details: The drive frame 7 is fixedly connected to the surface of the threaded sleeve 15. The other end of the threaded rod 14 is movably connected to a mounting plate via a bearing seat. The mounting plate is fixedly connected to the inner cavity of the protective box 2. When the servo motor 13 drives the threaded rod 14 to rotate, the threaded sleeve 15 moves axially, causing the drive frame 7 to move up and down. The guide block 16 is vertically welded to the back of the grinding motor 4 housing and, together with the top of the fixed cylinder 6, passes through two sets of V-shaped sliding frames 17. The sliding frames 17 are fixed to the side wall of the box at a set tilt angle. When the drive frame 7 moves up and down, it pushes... The fixed cylinder 6 moves along the inclined track of the sliding frame 17, converting the vertical displacement into the horizontal displacement, thereby achieving high-precision adjustment of the grinding roller 5. The telescopic rod 8 is vertically installed on one side of the inlet and outlet. The spring 18 normally pushes the baffle plate 9 to move inward. The surface of the fixed roller 20 embedded in the groove 19 is covered with a silicone layer, forming a rolling seal with the steel strip. When steel strips of different thicknesses pass through, the spring 18 adaptively compresses to maintain the airtightness of the protective box. There are two material rollers 21, one is an unwinding roller and the other is a winding roller, which realizes the function of rapid processing of steel strip.

[0032] The working principle of this utility model is as follows: the steel strip is drawn out from the material roller 21, enters the protective box 2 through the guide roller 22, and is then pressed by the fixed roller 20 on the baffle plate 9 to ensure that the steel strip is flat. The servo motor 13 is started by the external controller (existing technology) to drive the threaded rod 14 to rotate, which drives the threaded sleeve 15 to move along the threaded rod 14, thereby adjusting the height of the drive frame 7 and changing the position of the grinding motor 4 and the grinding roller 5 to achieve the adjustment of the grinding thickness.

[0033] Then, the external controller starts the grinding motor 4, which drives the grinding roller 5 to rotate and grind the surface of the steel strip. During the grinding process, the external controller starts the fan 10 to generate negative pressure, which draws the dust generated by grinding into the dust collection chamber 12 and transports it to the filter box 11 through the pipeline. After multiple layers of filtration, the clean air is discharged. The buffer mechanism composed of the telescopic rod 8 and the spring 18 allows the baffle plate 9 to automatically adjust its height according to the thickness of the steel strip, ensuring stable contact pressure between the steel strip and the grinding roller 5 and improving the dust removal effect.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
