Description

Technical Field

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

[0002] In the steel production and processing industry, steel billets, as a key intermediate product, are prone to defects such as oxide scale, burrs, and micro-cracks on their surface. If these defects are not thoroughly cleaned, they will directly affect the product precision of subsequent rolling and forging processes, and may even cause problems such as surface cracking and dimensional deviations in finished products. In severe cases, they may lead to the scrapping of the entire batch of products. Therefore, grinding and cleaning the surface of steel billets is a core step in ensuring the quality of steel products.

[0003] Existing grinding equipment often uses a rigid connection design for its grinding mechanism, which cannot be adjusted or moved during the grinding process and cannot adapt to steel billets of different sizes. Furthermore, the position of the grinding belt is prone to shifting during the grinding process, requiring the use of tools to correct the shift, which is a cumbersome, time-consuming, and labor-intensive process. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a steel billet grinding and cleaning device, which aims to solve the problems of poor adaptability of existing steel billet grinding and cleaning devices and the inability to effectively correct the deviation of the grinding belt.

[0005] The present invention adopts the following technical solution:

[0006] The billet grinding and cleaning device includes a platform, with a machine base and a material rack at the front and rear of the platform. A pair of grinding mechanisms are located between the machine base and the material rack, and the two grinding mechanisms can move relative to each other. The machine base is equipped with a material gripping assembly. Each grinding mechanism includes a slide, on which a grinding frame is mounted. A fixed plate is located on one side of the grinding frame, and a drive wheel is rotatably mounted on the other side. A pair of upper and lower rotating wheels are located on the fixed plate. A connecting plate is rotatably mounted above the grinding frame, and a correction plate is located on the connecting plate. A correction wheel is rotatably mounted on the correction plate. A grinding belt is fitted between the correction wheel, the drive wheel, and the upper and lower rotating wheels. A spring support rod is rotatably mounted on the grinding frame, and the top of the spring support rod is rotatably connected to the corresponding position of the connecting plate. A drive motor for driving the drive wheel to rotate is mounted on the grinding frame.

[0007] Furthermore, the front of the connecting plate is provided with a connecting seat, the correction plate is rotatably disposed inside the connecting seat, and a correction screw is screwed into the back of the connecting seat, with the front end of the correction screw abutting against the bottom of the correction plate.

[0008] Furthermore, the end of the connecting plate is provided with an adjustment handle.

[0009] Furthermore, the material gripping assembly includes a movable seat slidably mounted on the machine base, a material gripping chuck rotatably mounted on the movable seat, an adjusting motor mounted on the movable seat, the drive shaft of the adjusting motor being connected to the tail of the material gripping chuck, a movable lead screw rotatably mounted on the machine base, a movable lead sleeve inside the movable seat and mounted on the movable lead screw, and a movable motor mounted on the machine base, the drive shaft of the movable motor being connected to the movable lead screw.

[0010] Furthermore, the support plate at the top of the material rack is bent outward on both sides to form side plates, and several fixing sleeves are spaced apart on the side plates, with ball bearings embedded in the fixing sleeves.

[0011] Furthermore, the slide block contains a sliding threaded sleeve, and a sliding screw is rotatably mounted on the platform. The sliding threaded sleeve is installed on the sliding screw, and a pair of opposing threaded segments are formed on the sliding screw. A sliding motor is provided on the platform, and the drive shaft of the sliding motor is connected to the sliding screw.

[0012] The beneficial effects of this utility model are:

[0013] 1. This device achieves automatic gripping and conveying of steel billets through the material gripping component, eliminating the need for manual handling of steel billets and effectively reducing the labor intensity of operators; at the same time, the grinding mechanism can automatically complete the grinding operation on the surface of the steel billets, and the whole process does not require manual intervention, which greatly improves work efficiency.

[0014] 2. The grinding mechanism is equipped with a correction wheel and a spring support rod. If the grinding belt deviates from its course, it can be corrected by the correction wheel to ensure the stability of the grinding.

[0018] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figures 1-3 As shown, the billet grinding and cleaning device includes a platform 1, a machine base 2 and a material rack 3 are provided at the front and rear of the platform 1, and a pair of grinding mechanisms are provided between the machine base 2 and the material rack 3. The two grinding mechanisms can move relative to each other. The machine base 2 is provided with a material gripping assembly. The grinding mechanism includes a slide 4 and a grinding frame 5. A fixed plate 6 is provided on one side of the grinding frame 5, and a drive wheel 7 is rotatably provided on the other side. A pair of upper and lower rotating wheels 8 are provided on the fixed plate 6. A connecting plate 9 is rotatably provided above the grinding frame 5. A correction plate 10 is provided on the connecting plate 9. A correction wheel 11 is rotatably provided on the correction plate 10. A grinding belt 12 is sleeved between the correction wheel 11, the drive wheel 7, and the upper and lower rotating wheels 8. A spring support rod 13 is rotatably provided on the grinding frame 5. The top of the spring support rod 13 is rotatably connected to the corresponding position of the connecting plate 9. A drive motor 14 for driving the drive wheel 7 to rotate is provided on the grinding frame 5.

[0022] The steel billet to be ground is placed on the grinding platform. The gripping assembly grips the end of the billet and moves it forward, conveying it between the two grinding mechanisms. Then, the two grinding mechanisms move towards the billet until the grinding belt contacts the surface of the billet and maintains appropriate pressure. The drive motor is started, driving the drive wheel to rotate. The drive wheel drives the grinding belt to rotate, and the grinding belt, supported and guided by the rotating wheel and the straightening wheel, grinds both sides of the billet. During the grinding process, the gripping assembly slowly moves the billet forward.

[0023] As a specific structure, such as Figure 3 The front of the connecting plate 9 is provided with a connecting seat 15, and the correction plate 10 is rotatably disposed inside the connecting seat 15. A correction screw 16 is screwed into the back of the connecting seat 15, and the front end of the correction screw 16 abuts against the bottom of the correction plate 10.

[0024] If the grinding belt is found to be off-center during the grinding process, the correction screw can be rotated. The correction screw pushes the correction plate to rotate in the connecting seat, which in turn drives the correction wheel to move. Adjusting the angle of the correction wheel can correct the grinding belt.

[0025] The end of the connecting plate 9 is provided with an adjustment handle 18. In this structure, a spring support rod is rotatably mounted on the grinding frame, and the top of the spring support rod is rotatably connected to the corresponding position of the connecting plate. The spring support rod can provide a certain elasticity to the connecting plate, so that the grinding belt maintains a certain tension during the grinding process, thereby improving the grinding effect. Of course, if you want to remove the grinding belt, you can turn the adjustment handle downwards, and the connecting plate will move downwards accordingly. The support shaft of the spring support rod will retract, and the grinding belt will be in a relaxed state, at which point the grinding belt can be removed.

[0026] In this structure, combined Figures 1-2 The material gripping assembly includes a movable seat 19 slidably mounted on the machine base 2, a material gripping chuck 20 rotatably mounted on the movable seat 19, an adjusting motor 21 mounted on the movable seat 19, the drive shaft of the adjusting motor 21 being connected to the tail of the material gripping chuck 20, a movable lead screw 22 rotatably mounted on the machine base 2, a movable lead sleeve inside the movable seat 19 and mounted on the movable lead screw, and a movable motor 23 mounted on the machine base 2, the drive shaft of the movable motor being connected to the movable lead screw.

[0027] When the steel billet is gripped by the gripping assembly, the moving motor drives the moving screw to rotate, and the moving seat moves along the length of the moving screw towards the material rack under the action of the moving screw sleeve. When the gripping chuck moves to the end of the steel billet, it clamps the billet. Then, the moving motor reverses, conveying the steel billet between two grinding mechanisms, which grind the billet.

[0028] While grinding, the motor drives the material gripper chuck to rotate, which in turn rotates the billet, allowing the circumferential surface of the billet to be ground. Alternatively, the motor can be moved back and forth to grind different positions along the length of the billet.

[0029] In addition, such as Figure 1 The slide block 4 contains a sliding threaded sleeve, and the platform 1 is rotatably provided with a sliding threaded rod 24. The sliding threaded sleeve is installed on the sliding threaded rod 24, and a pair of opposing threaded sections are formed on the sliding threaded rod 24. The platform 1 is provided with a sliding motor 25, and the drive shaft of the sliding motor 25 is connected to the sliding threaded rod.

[0030] When the position of the left and right grinding mechanisms needs to be adjusted, the sliding motor drives the sliding screw to rotate. Since the sliding screw has a pair of reverse threaded sections, and the slides of the left and right grinding mechanisms are respectively connected to the two reverse threaded sections of the sliding screw through sliding sleeves, when the sliding screw rotates, the two slides will drive the corresponding grinding mechanisms to move simultaneously in opposite or relative directions, thereby achieving synchronous adjustment of the distance between the two grinding mechanisms.

[0031] Figure 2In this structure, the support plate at the top of the material rack 3 is bent outward on both sides to form side plates 31. Several fixing sleeves 32 are spaced apart on the side plates 31, and ball bearings 33 are embedded within each fixing sleeve 32. In this structure, the side plates can limit the movement of the steel billet, preventing it from slipping off the sides when placed on the material rack. The ball bearings convert the sliding friction between the steel billet and the material rack into rolling friction, reducing the frictional force when the steel billet moves on the material rack.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
