Description

Technical Field

[0001] This utility model relates to the field of grinding head manufacturing technology, and in particular to a vertical band saw for blanking grinding head production. Background Technology

[0002] In the industrial sector of grinding head production and blanking, efficient and precise processing equipment is crucial. A vertical band saw for grinding head blanking has emerged as a key piece of equipment for material cutting during the grinding head manufacturing process. With the increasing variety of grinding head products and the ever-increasing market demands for grinding head quality, higher standards are being placed on the performance of band saws. They must not only ensure cutting accuracy and efficiency but also flexibly handle the processing needs of grinding head blanks of different specifications. This vertical band saw aims to enhance overall processing capabilities through optimized structural design and functional configuration, providing the grinding head manufacturing industry with a more reliable and efficient blanking solution, improving production efficiency while ensuring product quality stability.

[0003] Traditional grinding head production blanking equipment is relatively simple in mechanical structure and technical principle. Most saws use a fixed clamping structure, fixing the workpiece to the worktable with simple bolt fastening. Its technical principle is mainly based on manual operation, relying on the worker's experience to adjust the workpiece position and fixing force. During the cutting process, the saw blade is mainly driven by a motor to reciprocate, thereby cutting the workpiece. Although this traditional equipment can complete basic blanking tasks, it has gradually revealed many shortcomings when facing complex and ever-changing production needs.

[0004] In actual production, a prominent problem with existing technologies is the difficulty in conveniently and stably fixing workpieces of different specifications. Because traditional band saws have fixed clamping structures and lack adaptive adjustment capabilities, when encountering grinding head blanks of varying sizes and shapes, workers often need to spend a significant amount of time and effort adjusting the clamps or using additional auxiliary tools to fix the workpieces. This not only reduces production efficiency but also makes it difficult to guarantee the stability of the fixation, easily leading to workpiece displacement during cutting, affecting cutting accuracy, and even causing workpiece scrap. At the same time, frequent clamping changes and adjustments increase the labor intensity of workers, hindering the continuity and efficiency of production. Therefore, a vertical band saw for grinding head production and blanking is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vertical band saw for blanking grinding heads, aiming to improve the problem that existing technologies cannot easily and stably process workpieces of different specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vertical band saw for blanking grinding head production includes a support frame, a cabinet fixedly connected to the top of the support frame, a saw blade inside the cabinet, a protective cover rotatably connected to the outer wall of the cabinet, a limit block at the bottom of the cabinet, a fixing plate at the top of the support frame, a fixing component at the top of the fixing plate, and a connecting component at the top of the fixing plate.

[0008] The fixing component includes a support column, which is disposed on the top of the fixing plate. A fixing ring is fixedly connected to the outer wall of the support column. A bearing is slidably connected to the outer wall of the support column. A fixing block is fixedly connected to the outer wall of the bearing.

[0029] 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.

[0030] Reference Figure 1 - Figure 3This utility model provides an embodiment of a vertical band saw for blanking grinding heads, comprising a support frame 1 made of high-quality, high-strength carbon steel. This carbon steel has particularly strong compressive strength and is not easily deformed, supporting the entire device. During sawing, it will not shift or shake regardless of vibration or uneven force, ensuring the stability of the band saw. A cabinet 4 is fixedly connected to the top of the support frame 1. The cabinet 4 is also made of sturdy and durable metal and is used to install and protect the sawing components. A saw blade 5 is installed inside the cabinet 4. The saw blade 5 is made of special alloy steel and has undergone fine processing and heat treatment. After this treatment, the saw blade 5 has a particularly high hardness and is very wear-resistant, so it can efficiently cut the grinding head material. The outer wall of the cabinet 4 is rotatably connected to a protective cover 6, which is generally made of transparent high-strength engineering plastic. In this way, it can not only prevent the chips from flying everywhere during the sawing process and ensure the safety of the operator, but also allow the operator to clearly see the sawing situation and facilitate operation. The bottom of the cabinet 4 is equipped with a limit block 3, the top of the support frame 1 is equipped with a fixing plate 2, the top of the fixing plate 2 is equipped with a fixing component, and the top of the fixing plate 2 is equipped with a connecting component.

[0031] The fixing assembly includes a support column 10, which is made of high-strength stainless steel. This stainless steel has excellent corrosion resistance and rigidity, and is not easy to rust or deform. The support column 10 is set on the top of the fixing plate 2. A fixing ring 9, also made of stainless steel, is fixedly connected to the outer wall of the support column 10. It provides a stable support point for the spring 11. A bearing 12 is slidably connected to the outer wall of the support column 10. A fixing block 8 is fixedly connected to the outer wall of the bearing 12. The fixing block 8 is made of sturdy aluminum alloy, which reduces the overall weight while ensuring strength. A soft pad 7 is fixedly connected to the bottom of the fixing block 8. The soft pad 7 is generally made of soft and elastic rubber material. Its function is to prevent damage to the surface of the workpiece when fixing it. The spring 11 is sleeved on the outer wall of the support column 10. The top of the spring 11 is fixedly connected to the bottom of the fixing ring 9, and the bottom of the spring 11 is fixedly connected to the top of the bearing 12.

[0032] Specifically, during the workpiece processing operation, we first use a specialized fixing device. When preparing to process the workpiece, the operator can directly pull the fixing block 8. The fixing block 8 is connected to the support column 10 via a bearing 12. When the fixing block 8 is pulled, the bearing 12 slides smoothly on the outer wall of the support column 10, and this action compresses the spring 11. Then, the operator needs to flexibly rotate the fixing block 8 according to the actual position of the workpiece, so that the fixing block 8 can be accurately aligned with the workpiece, thus achieving initial positioning of the workpiece. After positioning, the fixing block 8 is released. At this time, the spring 11 will rebound due to its elasticity, causing the fixing block 8 to move downwards, firmly fixing the workpiece. It is worth mentioning that the part of the fixing block 8 that contacts the workpiece is equipped with a soft pad 7, which can prevent unnecessary scratching of the workpiece surface during the fixing process. After fixing is completed, the saw blade 5 can be started to precisely process the workpiece.

[0033] Reference Figure 2 - Figure 3 The connecting component includes a connecting block 13, which is made of high-strength cast steel. This material has excellent pressure and impact resistance and can withstand various stresses generated by workpiece fixing and adjustment during the operation of the sawing machine. The bottom of the connecting block 13 is set on the top of the fixed plate 2. The fixed plate 2 has a slot 20 inside, and the connecting block 13 has a lifting groove 16 inside. A knob 14 is slidably connected inside the connecting block 13. The design of the knob 14 fully considers the convenience of the operator. Its surface has anti-slip texture, which makes it easy for the operator to turn and press by hand. The knob 14 is made of sturdy engineering plastic, which has both strength and light weight, making it easy to operate. A connecting post 18 is fixedly connected to the bottom of the knob 14. A limiting ring 15 is rotatably connected to the outer wall of the connecting post 18. A locking post 19 is fixedly connected to the bottom of the connecting post 18. The outer wall of the locking post 19 is slidably connected to the inside of the locking groove 20. The outer wall of the limiting ring 15 is slidably connected to the inside of the lifting groove 16. A second spring 17 is sleeved on the outer wall of the connecting post 18. The bottom of the second spring 17 is fixedly connected to the inner wall of the lifting groove 16, and the top of the second spring 17 is fixedly connected to the bottom of the limiting ring 15.

[0034] Specifically, in actual processing, situations often arise where workpieces of different sizes need to be handled. In these cases, the special adjustment device on our equipment plays a crucial role. When faced with workpieces of varying sizes, the operator simply presses knob 14. Knob 14 is tightly connected to connecting post 18; pressing knob 14 causes connecting post 18 to move smoothly downwards. Connecting post 18 is connected to limiting ring 15, so limiting ring 15 also moves downwards, compressing spring 17. Next, rotating knob 14 causes locking post 19 to rotate 90 degrees. After rotation, releasing knob 14 allows spring 17 to quickly rebound, returning locking post 19 to its original position. Connecting block 13 can then be easily removed. The operator can adjust connecting block 13 to the appropriate position according to the actual size of the workpiece, thus achieving accurate fixing of workpieces of different sizes and greatly improving processing efficiency and precision.

[0035] Working principle: When processing the workpiece, the fixed block 8 can be pulled, which drives the bearing 12 to slide on the outer wall of the support column 10 and compresses the spring 11. Then, according to the position of the workpiece, the fixed block 8 is rotated to accurately fix the workpiece. Then, the fixed block 8 is released, and the spring 11 rebounds and drives the fixed block 8 to move downward to fix the workpiece. At the same time, the soft pad 7 contacts the surface of the workpiece to prevent scratching. Then, the saw blade 5 is started for processing.

[0036] In addition, when dealing with workpieces of different sizes, the knob 14 can be pressed to move the connecting post 18 downwards, which in turn moves the limiting ring 15 downwards to compress the second spring 17. Then, the knob 14 can be rotated to rotate the locking post 19 to ninety degrees. After releasing the knob 14, the second spring 17 will rebound and move the locking post 19 back to its original position, allowing the connecting block 13 to be removed and its position changed. This makes it convenient to accurately fix workpieces of different sizes.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
