Description

Technical Field

[0001] The present invention relates to the technical field of bar processing, and particularly relates to a carbide bar end grinding device and a grinding method. Background Art

[0002] Carbide is an alloy material made by powder metallurgy process from refractory metal hard compounds and binding metals. Carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc. Carbide is widely used as a tool material, such as turning tools, milling cutters, planing cutters, drills, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be used to cut difficult-to-machine materials such as heat-resistant steel, stainless steel, high-manganese steel, tool steel, etc. The end face of a bar made of carbide is usually relatively rough. In order to ensure the flatness and smoothness of both end faces of the bar, it is usually necessary to use a grinding device to grind the end face of the bar.

[0003] Commonly, the end face grinding of bars is a key process to ensure the dimensional accuracy and surface quality of bars. Existing equipment mostly adopts a production mode of processing single bars one by one, with relatively low overall grinding efficiency.

[0015] The present invention also provides a grinding method, which includes the following steps: S1. Arrange several bars side by side and flat on the top of the base. One ends of the multiple bars are in contact with the positioning plate. The multiple bars are located between the four limiting rods. Start the two electric motors II. The two electric motors II drive the four limiting rods to rotate simultaneously. The four limiting rods rotate towards both sides simultaneously. The bottom ends of the four limiting rods are rotated above the lower pressing plate. The two electric motors II are turned off; S2. Start two hydraulic cylinders 1. The output rods of the two hydraulic cylinders 1 gradually retract inward. The frame-shaped block and the lower pressing plate move downward together until the rubber pads at the bottom of the lower pressing plate come into contact with multiple bars, firmly pressing the bars. Then, the two hydraulic cylinders 1 are closed. Next, start the electric motor 1. The output shaft of the electric motor 1 drives the threaded rod 1, and the adjusting block 1 slides on the threaded rod 1. The adjusting block 1 moves to a predetermined position. Then, the output shaft of the electric motor 1 starts to rotate in the reverse direction, driving the adjusting block 1 to slide in the reverse direction. Driven by the forward and reverse reciprocation of the electric motor 1, the adjusting block 1 slides left and right reciprocally on the threaded rod 1, driving the lower pressing plate to move back and forth. The lower pressing plate then pushes the multiple bars to roll back and forth on the base; S3. Start the electric motor 5 and the electric motor 4 located at the rear. The electric motor 5 drives the diamond grinding wheel to rotate through the synchronous rod. The electric motor 4 drives the double-headed threaded rod to rotate. The two sliding blocks move simultaneously on the double-headed threaded rod and approach each other. The two sliding blocks slide and drive the four hinge rods to rotate. The diamond grinding wheel in the rotating state is lifted through the connecting frame. After the two sliding blocks move to the predetermined position, the output shaft of the electric motor 4 rotates in the reverse direction, driving the diamond grinding wheel to move downward. Repeat this process to drive the diamond grinding wheel to slide up and down. Then, start the corresponding electric motor 3. The electric motor 3 drives the corresponding threaded rod 2, and the sliding block moves on the threaded rod 2 and moves in the direction of the electric motor 3. The diamond grinding wheel in the rotating state and moving up and down gradually approaches the rear ends of the multiple bars. The diamond grinding wheel evenly grinds the end faces to keep the end faces flat and smooth; S4. After the grinding is completed, turn off the electric motor 5, and the diamond grinding wheel stops rotating. Then, start two hydraulic cylinders 2. The output rods of the two hydraulic cylinders 2 output outward. The two hydraulic cylinders 2 drive the positioning plate to slide upward through the strip-shaped plate. The positioning plate slides away from the front ends of the multiple bars. According to the above operations, start the electric motor 5 located in the front, that is, close to the positioning plate. The diamond grinding wheel in the front rotates. Start the corresponding electric motor 4 to move the diamond grinding wheel up and down. Finally, start the corresponding electric motor 3 to adjust the direction of the diamond grinding wheel. The diamond grinding wheel approaches the front ends of the multiple bars and grinds this position. After the grinding work is completed, turn off the electric motor 5. Start the two electric motors 3 in the reverse direction to move the two diamond grinding wheels away from both ends of the bars. Then, start the two hydraulic cylinders 1. Lift the lower pressing plate to remove the ground bars from the base, facilitating the next round of grinding; During the grinding process, when it is necessary to grind a bar with a larger diameter, the double-axis motor is started. The output shaft of the double-axis motor drives two horizontal circular rods to move simultaneously. Two adjusting blocks II slide on the two horizontal circular rods and move away from each other. The two adjusting blocks II can adjust the distance between the four limiting rods, and the four limiting rods can accommodate a bar with a larger diameter. By controlling the two hydraulic cylinders I, the downward movement range of the lower pressing plate can be adjusted to ensure that the lower pressing plate can adapt to the height of the bar. The position of the diamond grinding wheel at the rear is adjusted by the electric motor III. When the bar is longer, the electric motor III drives the diamond grinding wheel away from the bar, leaving a space for the bar to be accommodated, which is convenient for grinding bars of different specifications within a certain range.

[0016] Compared with the related art, the carbide bar end grinding device and grinding method provided by the present invention have the following beneficial effects: The present invention provides a carbide bar end grinding device and grinding method. A push plate is arranged on one side of the gate plate. The push plate is usually suspended at a relatively high position. Once the gate plate is lowered to cut off the water flow, only the drive motor III and the drive motor II need to be started successively to adjust the height and position of the push plate, and the push plate is used to clean the sediment at the bottom of the gate plate, providing assistance for the downward movement of the gate plate and cleaning the space where the bottom of the gate plate is about to contact, so as to improve the fit between the gate plate and the inner wall of the bottom of the gate pier, thereby avoiding the influence of sediment accumulation on the water interception effect of the gate plate. After the push plate is used, by starting the drive motor III and the drive motor II in the reverse direction, the push plate can be adjusted to the initial position, thus preventing the push plate from interfering with the use of the gate plate.

[0021] In order to grind the two ends of multiple bars separately in sequence, improve the operation efficiency of grinding, and facilitate the adaptation to bars of different lengths. In this method, two adjusting mechanisms are provided at the bottom of the base 1. Both adjusting mechanisms include: two welding blocks 25, electric motor three 26, screw rod two 27, sliding block 28, bearing seat 29, two square blocks 30, electric motor four 31, double-headed screw rod 32, two sliding blocks 33, four hinge rods 34, four adapter blocks 35, connecting frame 36, synchronizing rod 37, diamond grinding wheel 38 and electric motor five 39.

In the two adjusting mechanisms, the lengths of the two screw rods two 27 are different, and the positions of the two sliding blocks 28 on the two screw rods two 27 are also different, which is convenient for adapting to the length and the positions of the two ends of the bar.

[0022] In order to ensure the stability of the installation of the two hydraulic cylinders one 2 and the two hydraulic cylinders two 22. In this method, two vertical plates are fixedly installed on the top of the base 1. Two U-shaped clamps one are fixedly installed on each of the two vertical plates. The four U-shaped clamps one are respectively fixedly connected to the two hydraulic cylinders one 2. Two U-shaped clamps two are fixedly installed on both sides of the fixing frame 20. The four U-shaped clamps two are respectively fixedly connected to the two hydraulic cylinders two 22.

[0023] In order to limit the movement tendency of the adjusting block one 7 and the adjusting block two 14 and increase their stability. In this method, two docking round rods one are fixedly installed between the inner walls on both sides of the frame-shaped block 4. Both docking round rods one are slidably connected to the adjusting block one 7. Four docking round rods two are fixedly installed among the four support blocks 12. The four docking round rods two are respectively slidably connected to the two adjusting blocks two 14.

[0024] In order to make the two ends of the positioning plate 23 bear force, increase its solidity when placed, and at the same time increase the friction of the lower pressure plate 9, so that the lower pressure plate 9 can drive multiple rods to roll, in this method, a brake block is fixedly installed at the bottom of the base 1, and the brake block is L-shaped. The brake block is slidably connected to the bottom of the positioning plate 23, and a rubber pad is fixedly installed at the bottom of the lower pressure plate 9.

[0025] Similarly, in order to ensure the stability of the two sliding blocks 28 and the two sliding blocks 33 and limit their movement trends, in this method, in the two adjustment mechanisms, four butt-jointed circular rods three are fixedly installed between the four welding blocks 25, and the four butt-jointed circular rods three are respectively slidably connected to the two sliding blocks 28, and four butt-jointed circular rods four are fixedly installed between the four square blocks 30, and the four butt-jointed circular rods four are respectively slidably connected to the two sliding blocks 33, and the two double-headed threaded rods 32 are fixedly sleeved with sleeve blocks, and the two connecting frames 36 are provided with side grooves on the sides close to each other, and the bottoms of the two bearing seats 29 are fixedly installed with four universal wheels one, and the two sleeve blocks are sleeved on the center positions of the two double-headed threaded rods 32 to facilitate limiting the moving range of the four sliding blocks 33, and the eight universal wheels one can support the two bearing seats 29 and facilitate the position movement of the two bearing seats 29.

[0026] In this embodiment, a grinding method is also provided, which is as follows: In the present invention, in the initial state, the four limit rods 19 are distributed vertically downward, the output rods of the two hydraulic cylinders 22 are in a retracted state, the positioning plate 23 is at the lowest point on one side of the base 1, and the output rods of the two hydraulic cylinders 1 2 are in an output-outward state, the lower pressure plate 9 is lifted, and sufficient space is reserved between the lower pressure plate 9 and the base 1.

[0027] When it is necessary to grind the end faces of multiple bars, lay several bars side by side on the top of the base 1 so that one end of the multiple bars is in contact with the positioning plate 23, and the multiple bars are located between the four limit rods 19, which is convenient for determining the stacking position between the multiple bars so that the bars fit together to prevent the bars from rolling to both sides at will. Then start the two electric motors 17, and the two electric motors 17 drive the four limit rods 19 to rotate at the same time. The four limit rods 19 rotate to both sides at the same time until the bottom ends of the four limit rods 19 are rotated to the top of the lower pressure plate 9, and the two electric motors 17 are turned off to prevent the four limit rods 19 from affecting the subsequent movement of the bars.

[0028] After that, start two hydraulic cylinders-2. The output rods of the two hydraulic cylinders-2 will gradually retract inward, driving the frame-shaped block 4 and the lower pressing plate 9 to move downward together until the rubber pad at the bottom of the lower pressing plate 9 comes into contact with multiple bars, firmly pressing the bars. Then, the two hydraulic cylinders-2 are closed. After that, start the electric motor-5. The output shaft of the electric motor-5 will drive the threaded rod-6 fixedly connected thereto, and the adjustment block-7 will slide on the threaded rod-6. After the adjustment block-7 moves to a predetermined position, the output shaft of the electric motor-5 will start to rotate in the reverse direction, driving the adjustment block-7 to slide in the reverse direction. Driven by the forward and reverse reciprocation of the electric motor-5, the adjustment block-7 slides back and forth left and right on the threaded rod-6, thereby driving the lower pressing plate 9 to move back and forth. The lower pressing plate 9 then pushes the multiple bars to roll back and forth on the base 1.

[0029] After that, start the electric motor-five 39 and the electric motor-four 31 located at the rear. The electric motor-five 39 drives the diamond grinding wheel 38 to rotate through the synchronizing rod 37 fixedly connected thereto, while the electric motor-four 31 drives the double-headed threaded rod 32 to rotate. The two sliding blocks 33 move on the double-headed threaded rod 32 and approach each other. While the two sliding blocks 33 slide, they drive the four hinge rods 34 to rotate, and then lift the rotating diamond grinding wheel 38 through the connecting frame 36. When the two sliding blocks 33 move to a predetermined position, the output shaft of the electric motor-four 31 will start to rotate in the reverse direction, driving the diamond grinding wheel 38 to move downward. Repeat this process to drive the diamond grinding wheel 38 to slide up and down. After that, start the corresponding electric motor-three 26. The electric motor-three 26 drives the corresponding threaded rod-two 27. The sliding block 28 moves on the threaded rod-two 27 and moves in the direction of the electric motor-three 26. The rotating and moving up and down diamond grinding wheel 38 will gradually approach the rear ends of the multiple bars and evenly grind their end faces through the diamond grinding wheel 38 to keep the end faces flat and smooth.

[0030] After the rear ends of multiple bars are polished, the electric motor five 39 can be turned off to stop the rotating diamond grinding wheel 38. Then, start the two hydraulic cylinders two 22. The output rods of the two hydraulic cylinders two 22 will gradually extend outwards. The two hydraulic cylinders two 22 drive the positioning plate 23 to slide upwards through the strip plate 21, so that the positioning plate 23 slides away from the front ends of the multiple bars. Then, according to the above operations, start the electric motor five 39 located in the front, that is, close to the positioning plate 23, to make the diamond grinding wheel 38 in the front rotate. Then, start the corresponding electric motor four 31 to move the diamond grinding wheel 38 up and down. Finally, start the corresponding electric motor three 26 to adjust the direction of the diamond grinding wheel 38, so that the diamond grinding wheel 38 approaches the front ends of the multiple bars and grinds this position. After the grinding work is completed, turn off the electric motor five 39, and start the two electric motors three 26 in the reverse direction to make the two diamond grinding wheels 38 move away from both ends of the bar. Then, start the two hydraulic cylinders one 2, and raise the lower pressing plate 9 to remove the ground bar from the base 1, so as to facilitate the next round of grinding.

[0031] During the grinding process, when grinding bars with a larger diameter are needed, first start the double-shaft motor 11. The output shafts of the double-shaft motor 11 drive the two transverse circular rods 13 to move simultaneously. The two adjusting blocks two 14 will slide on the two transverse circular rods 13 and move away from each other. The two adjusting blocks two 14 can adjust the distance between the four limiting rods 19, so that the four limiting rods 19 can accommodate bars with a larger diameter. By controlling the two hydraulic cylinders one 2, the range of the downward movement of the lower pressing plate 9 can be adjusted to ensure that the lower pressing plate 9 can adapt to the height of the bar. The position of the diamond grinding wheel 38 at the rear is adjusted by the electric motor three 26. When the bar is longer, the electric motor three 26 drives the diamond grinding wheel 38 away from the bar, leaving a space for the bar to be accommodated, which is convenient for applying bars of different specifications within a certain range.

[0032] Compared with the related art, the carbide bar end grinding device and grinding method provided by the present invention have the following beneficial effects: Through the synergistic effect of the four limiting rods 19 and the lower pressing plate 9, multiple bars can be fixed side by side, so as to complete the grinding of multiple bars at one time, thereby improving the efficiency. The reciprocating rolling of the lower pressing plate 9 is realized by driving the threaded rod 6 by the electric motor 1, so that the bars rotate evenly, ensuring that the end faces of multiple bars are ground flat, shortening the single processing time. Both diamond grinding wheels 38 at the front and rear ends can be independently controlled. After the rear-end grinding is completed, the front diamond grinding wheel 38 is immediately started, without manual turning, reducing the time loss during the switching process. The biaxial motor 11 drives the transverse circular rod 13 to adjust the distance between the four limiting rods 19, facilitating the adaptation to bars of different diameters. The hydraulic cylinder 1 controls the downward pressing stroke of the lower pressing plate 9 to ensure that the rubber pad can effectively press the bars with different diameters. In addition, the two electric motors 3 26 adjust the horizontal position of the diamond grinding wheels 38. The electric motor 3 26 located at the rear can simultaneously control the moving range of the diamond grinding wheels 38 within a larger range, facilitating the adaptation to bars of different lengths between the two diamond grinding wheels 38 and improving the applicability of the equipment.

[0033] Second Embodiment: Based on the cemented carbide bar end face grinding device and grinding method provided in the first embodiment of the present application, the second embodiment of the present application proposes another cemented carbide bar end face grinding device and grinding method. The second embodiment is merely a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0034] The following further describes the second embodiment of the present invention in conjunction with the drawings and embodiments.

[0035] Please refer to Figures 11 - 14, in the carbide bar end grinding device: Among the two adjusting mechanisms, air supply pipes 40 are arranged at the tops of the two connecting frames 36. Five shunt pipes 41 are fixedly installed on one side of the two air supply pipes 40 close to each other. The five shunt pipes 41 are linearly distributed at equal intervals. Long strip plates 42 are fixedly installed on the tops of the two connecting frames 36. The two long strip plates 42 are respectively in contact with the multiple shunt pipes 41, playing a role in supporting the multiple shunt pipes 41. Air inlet hoods 43 are fixedly installed at one ends of the multiple shunt pipes 41 away from the two air supply pipes 40. Docking pipes 44 are fixedly installed at one ends of the two air supply pipes 40. The two docking pipes 44 are both L-shaped. One ends of the two air supply pipes 40 away from the two docking pipes 44 are sealed. Bellows 45 are fixedly installed at one ends of the two docking pipes 44 away from the two air supply pipes 40. A water storage tank 46 is arranged on one side of the base 1. The top of the water storage tank 46 is open. Two placement platforms 47 are fixedly installed on one side of the water storage tank 46. Air extraction pumps 48 are fixedly installed on the tops of the two placement platforms 47. The air inlets of the two air extraction pumps 48 are respectively fixedly connected to one ends of the two bellows 45 away from the two docking pipes 44. Delivery pipes 49 are fixedly installed on the air outlets of the two air extraction pumps 48. The bottom ends of the two delivery pipes 49 both extend into the water storage tank 46.

[0036] In order to ensure the firm installation of the air supply pipes 40 and prevent excessive impurities from entering the multiple shunt pipes 41, in this method, among the two adjusting mechanisms, two U-shaped clamps III are fixedly installed on the tops of the two connecting frames 36. The four U-shaped clamps III are respectively fixedly connected to the two air supply pipes 40. Connecting sleeves are threadedly sleeved on the multiple air inlet hoods 43. Filters are fixedly installed on the multiple connecting sleeves. Four universal wheels II are fixedly installed at the bottom of the water storage tank 46. A handle is fixedly installed on one side of the water storage tank 46. A sewage discharge pipe is fixedly installed on one side of the water storage tank 46. A valve is fixedly installed on the sewage discharge pipe. The sewage discharge pipe facilitates the discharge of the sewage in the water storage tank 46.

[0037] In this embodiment Before the equipment is used, an appropriate amount of clean water is placed in the water storage tank 46 to ensure that the clean water submerges the bottom ends of the two delivery pipes 49. During the grinding process, the two air extraction pumps 48 are started. The two air extraction pumps 48 extract the air containing debris through the corresponding air supply pipes 40 and shunt pipes 41, and discharge the air containing debris into the water storage tank 46 through the delivery pipes 49. The water in the water storage tank 46 is used to filter the debris to achieve the dust removal effect. The purified air is discharged from the top of the water storage tank 46, while the debris is mixed with the water and left in the water storage tank 46. The sewage mixed with debris is subsequently discharged through the sewage discharge pipe. The filters and the connecting sleeves prevent large particle debris from entering the shunt pipes 41, avoiding blockage of the pipelines. Through the collection of debris, it is helpful to improve the working environment and protect the equipment from the influence of dust.

[0038] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
