A device for grinding the end of a round die steel

Abstract

This invention discloses a grinding device for the end of mold steel round bars, belonging to the technical field of round bar grinding devices. It includes a conveyor table, with a second auxiliary sleeve on the top of the conveyor table. A positioning sleeve for fixing the round bar is rotatably connected to the side of the second auxiliary sleeve. The positioning sleeve has symmetrical movable grooves at both ends, and friction wheels are movably connected to the inner cavity of the movable grooves. Multiple friction wheels synchronously abut against the outer wall of the round bar, ensuring that the friction wheels always fit against the circumferential surface of the round bar according to its diameter. When the drive gear rotates, it drives the positioning sleeve to rotate continuously, thus causing the round bar clamped inside the positioning sleeve to rotate synchronously and continuously. This allows the grinding wheel to continuously and uniformly grind different areas of the round bar end, avoiding the problem of repeated manual rotation of the round bar, reducing the labor intensity of workers, and improving the smoothness of the ground round bar end.

Description

Technical Field

[0001] This invention relates to the technical field of round steel grinding equipment, and specifically to a grinding device for the ends of mold steel round steel. Background Technology

[0002] As a commonly used raw material in mold manufacturing, machining, and precision parts processing, round steel for molds often has burrs, oxide layers, cutting tilts, and uneven end faces at its ends after cutting. Therefore, the ends of the round steel need to be ground to improve the clamping stability and machining accuracy during subsequent processing.

[0003] In the existing technology, when grinding the end of the mold steel round bar, a hand-held grinder or a fixed grinding wheel machine is usually used to process the end of the round bar. Since the end of the round bar has a circular structure, in order for the grinder to grind different positions of the end of the round bar evenly, the operator often needs to continuously rotate the round bar so that different areas of the end face of the round bar come into contact with the grinding wheel in turn, thereby completing the grinding process of the entire end face.

[0004] In summary, existing technologies suffer from several drawbacks. Firstly, the weight of round steel bars, especially large-diameter mold steel bars, necessitates continuous manual rotation during grinding. This not only increases labor intensity but also increases the risk of misalignment or wobbling, leading to uneven grinding at the ends, affecting the flatness of the end face, and reducing the quality of subsequent processing. Secondly, existing grinding equipment generates a large amount of high-temperature sparks and metal shavings during operation. Most equipment lacks effective protective structures, causing sparks to easily fly outwards and onto the operator's body or clothing. This not only risks burns but also poses a safety hazard of igniting surrounding flammable materials, thus compromising the safety of equipment use. Summary of the Invention

[0005] This invention provides a grinding device for the ends of mold steel round bars, which can solve the problem in the prior art that, due to the large weight of the round bars themselves, especially large-diameter mold steel round bars, the round bars need to be continuously rotated manually during the grinding process. This not only results in high labor intensity, but also in the round bars being prone to deviation or shaking during rotation, leading to uneven grinding of the ends, affecting the flatness of the end face, and reducing the quality of subsequent processing.

[0016] The present invention provides a grinding device for the ends of mold steel round bars, which, compared with the prior art, has the following beneficial effects, but is not limited to: 1. This invention uses multiple friction wheels that synchronously abut against the outer wall of a round steel bar. Depending on the diameter of the round steel bar, the friction wheels can always be in contact with the circumferential surface of the bar. This allows the friction wheels to stably drive the round steel bar to rotate synchronously. Furthermore, the meshing transmission between the driving gear and the driven gear allows the driving gear to continuously rotate the positioning sleeve, thus causing the round steel bar clamped inside the positioning sleeve to rotate synchronously and continuously. This enables the grinding wheel to continuously and evenly grind different areas at the end of the round steel bar, avoiding the problem of repeated manual rotation of the round steel bar, reducing the labor intensity of workers, and improving the smoothness of the ground round steel bar end.

[0017] 2. This invention uses a protective sleeve placed on the outside of the grinding wheel and an arc-shaped isolation plate placed between the grinding motor and the handle. The protective sleeve can initially block the sparks and debris generated during the grinding process, while the arc-shaped isolation plate can guide and isolate the sparks, causing them to fly away from the workers, thereby reducing the risk of sparks splashing onto the workers' bodies and improving the safety of the device during use.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings showing multiple embodiments according to this application. It should be understood that the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments described in this application without creative effort will fall within the scope of protection of this application.

[0022] like Figure 1-6 As shown, a grinding device for the end of a mold steel round bar includes a grinding component 2 for grinding the end of the round bar, a hoisting component 3 for adjusting the position of the grinding component 2 is provided on the top of the grinding component 2, and a rotating component 1 for supporting the round bar and allowing it to rotate continuously is provided on one side of the grinding component 2. The rotating assembly 1 includes a conveyor table 11, which is fixedly installed on the ground or the top of the processing platform. A second auxiliary sleeve 16 is provided on the top of the conveyor table 11. The second auxiliary sleeve 16 is used to initially guide and support the round steel to prevent the round steel from shifting during the conveying process. A positioning sleeve 19 for fixing the round steel is rotatably connected to the side of the second auxiliary sleeve 16. The positioning sleeve 19 can rotate around the axis of the second auxiliary sleeve 16, so that the round steel clamped inside rotates synchronously when the positioning sleeve 19 rotates, so as to realize continuous grinding at different positions of the end of the round steel, reduce the labor intensity of manually rotating the round steel repeatedly, and improve the grinding uniformity of the end of the round steel. The two ends of the positioning sleeve 19 are symmetrically provided with movable grooves 190, and friction wheels 195 are movably connected in the inner cavity of the movable grooves 190. The grinding assembly 2 includes a grinding motor 21. One end of the grinding motor 21 is provided with a connecting shaft 22. A grinding wheel 24 for grinding the end of the round steel is rotatably connected to the side of the connecting shaft 22. The other end of the grinding motor 21 is provided with an arc-shaped isolation plate 27 for protection. The hoisting assembly 3 includes a support frame 31, a movable rod 32 is slidably connected to the top of the support frame 31, a connecting rod 33 is fixedly connected between the movable rods 32, and a suspension member 210 for hoisting the grinding assembly 2 is fixedly connected to the bottom of the connecting rod 33.

[0023] The conveyor table 11 has first slide rails 12 symmetrically arranged at both ends. A first lead screw 14 is rotatably connected to the middle of the first slide rail 12. The first lead screw 14 has limiting plates 13 symmetrically arranged at both ends for limiting the ends of the round steel. By rotating the first lead screw 14, the two sets of limiting plates 13 can be driven to move closer or further apart, thereby limiting and supporting the ends of the round steel according to different lengths of round steel, and preventing the round steel from axially moving during rotation. A groove 110 is opened at one end of the conveyor table 11 near the grinding assembly 2. A second lead screw 111 is rotatably connected inside the groove 110. A second motor 113 is provided on the side of the conveyor table 11. The output end of the second motor 113 is fixedly connected to the second lead screw 111. A first slide rail 12 is provided above the slide groove 110 and is movably connected to the top of the conveyor table 11 through the second lead screw 111. When the second motor 113 is working, it can drive the second lead screw 111 to rotate. The first slide rail 12 is movably connected to the surface of the second lead screw 111 through a threaded structure, so that the first slide rail 12 can move along the length of the conveyor table 11 to adjust the support position according to the round steel of different lengths or positions.

[0024] One end of the positioning sleeve 19 is provided with a first auxiliary sleeve 15. Symmetrical limit grooves 1900 are formed on both sides of one end of the positioning sleeve 19. Second slide rails 191 are provided at the upper and lower ends of the limit grooves 1900. A first motor 196 is slidably connected to the surface of the second slide rails 191. A slider 192 is fixedly connected to the output end of the first motor 196. One end of the slider 192 is provided with a friction wheel 195 for contacting the circumferential side of the round steel. An adjusting nut 194 is provided through the side of the movable groove 190. By rotating the adjusting nut 194, the position of the slider 192 can be finely adjusted to accommodate round steel of different diameters, improving the device's adaptability to round steel of different specifications. The first motor 196 is movably connected inside the limit groove 1900 through the adjusting nut 194. A spring 193 is provided on the side of the slider 192. One end of the spring 193 is fixedly connected to the side wall of the limiting groove 1900. The slider 192 and the second slide rail 191 form a guiding sliding fit, so that the slider 192 can only move in the radial direction, thereby improving the clamping stability. Tightening the adjusting nut 194 can drive the slider 192 to move along the direction of the second slide rail 191. The friction wheel 195 is used to fit against the circumferential side of the round steel. By having multiple friction wheels 195 simultaneously abut against the outer wall of the round steel, the friction wheels 195 can always fit against the circumferential side of the round steel according to the different diameters of the round steel, preventing the round steel from slipping. The elastic effect of the spring 193 can provide a continuous inward elastic clamping force to the slider 192, so that the friction wheels 195 always fit against the outer wall of the round steel, thereby improving the clamping stability. At the same time, it can play a buffering and shock-absorbing role when the round steel is subjected to vibration, reducing the shaking of the round steel.

[0025] A driven gear 17 is provided at the connection between the positioning sleeve 19 and the second auxiliary sleeve 16. A driving gear 18 meshes with the surface of the driven gear 17. The driving gear 18 is rotatably connected to the surface of the second auxiliary sleeve 16. When the driving gear 18 is driven to rotate by an external drive source, it can drive the driven gear 17 to rotate synchronously, thereby stabilizing the rotation of the positioning sleeve 19 and achieving continuous rotation of the round steel. This allows the grinding wheel 24 to uniformly grind different circumferential areas at the end of the round steel. The second auxiliary sleeve 16 is not connected to the positioning sleeve. A plurality of auxiliary grippers 112 for clamping and positioning the outer wall of the round steel are arranged around one side of the sleeve 19. The multiple auxiliary grippers 112 are distributed at intervals along the circumference of the second auxiliary sleeve 16, and the clamping ends of the auxiliary grippers 112 all extend toward the center of the second auxiliary sleeve 16. When the round steel is inserted into the second auxiliary sleeve 16, the multiple auxiliary grippers 112 can simultaneously abut against the outer wall of the round steel, thereby limiting and clamping the round steel, keeping the round steel coaxial during rotation, reducing the shaking of the round steel, and improving the grinding stability.

[0026] The bottom of the suspension component 210 is equipped with a steel wire rope 29 for hoisting. A connecting block 26 is fixedly connected to the bottom of the steel wire rope 29. A handle 28 is provided at one end of the grinding motor 21. An arc-shaped isolation plate 27 is located at the connection between the grinding motor 21 and the handle 28. When the grinding motor 21 is working, it can drive the connecting shaft 22 to rotate at high speed, thereby driving the grinding wheel 24 to grind the end of the round steel. The arc-shaped isolation plate 27 adopts an arc-shaped covering structure, and its arc surface is set towards the side of the grinding wheel 24, so as to block and guide the sparks generated during the grinding process of the grinding wheel 24, so that the sparks fly downward along the arc surface or away from the operator, avoiding the sparks from directly splashing onto the operator's body, improving the safety of equipment use. The operator can use the handle 28 to make auxiliary adjustments to the grinding component 2, improving the convenience of operation.

[0027] The grinding wheel 24 is provided with a protective sleeve 23 for initial protection. The top of the connecting shaft 22 is provided with a third lead screw 25. The top of the third lead screw 25 is rotatably connected to the inside of the connecting block 26. The protective sleeve 23 can initially block some of the sparks and debris generated when the grinding wheel 24 is working, reducing the problem of sparks flying everywhere. Through the cooperation between the third lead screw 25 and the connecting block 26, the height and angle of the grinding assembly 2 can be adjusted, so that the grinding wheel 24 can fit more precisely on the end of the round steel, improving the grinding accuracy.

[0028] Rollers 35 are provided at both ends of the movable rod 32, and a third motor 34 is provided on the side of the rollers 35. The movable rod 32 moves at both ends of the support frame 31 via the rollers 35. The third motor 34 can drive the rollers 35 to rotate, thereby driving the movable rod 32 to move along the support frame 31, so that the grinding assembly 2 can be adjusted in position along the length of the round steel, so as to grind different positions and improve the flexibility of the device.

[0029] The working principle of this invention is as follows: The round steel is placed on the top of the conveyor table 11, and the two ends of the round steel are limited by the limiting plate 13. Tightening the adjusting nut 194 can drive the slider 192 to move along the direction of the second slide rail 191. The friction wheel 195 is used to fit against the circumferential side of the round steel. By having multiple friction wheels 195 simultaneously abut against the outer wall of the round steel, the friction wheels 195 can always fit against the circumferential side of the round steel according to the different diameters of the round steel, thereby improving the clamping stability. At the same time, it can play a buffering and shock-absorbing role when the round steel is subjected to vibration, reducing the shaking of the round steel. Simultaneously, the grinding motor 21 is started, driving the grinding wheel 24 to rotate at high speed. Under the movement and adjustment of the hoisting component 3, the grinding wheel 24 is brought into contact with the end of the round steel for grinding. During the grinding process, the round steel can rotate automatically and continuously, so that the grinding wheel 24 can continuously and evenly grind different areas of the end of the round steel, avoiding frequent manual rotation of the round steel. At the same time, the protective sleeve 23 and the arc-shaped isolation plate 27 can block and guide the grinding sparks, reduce the risk of burns to the workers caused by the sparks, and improve the safety of the equipment.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
