Description

Technical Field

[0001] This utility model relates to the field of twist drill bit production technology, specifically to a rough grinding machine for twist drill bit production. Background Technology

[0002] In the manufacturing process of twist drill bits, rough grinding is a crucial preliminary step to ensure the quality of subsequent fine grinding and the final forming accuracy. Its core function is to perform preliminary shaping of the drill bit stock, removing excess material to form a blank structure close to the finished product size. During this processing stage, to avoid the high temperatures generated by high-speed grinding leading to deterioration of the stock material properties (such as annealing and decreased hardness) and increased wear on the grinding wheel, it is usually necessary to continuously spray coolant to cool and lubricate the grinding area. Simultaneously, the grinding process generates a large amount of metal shavings. If the mixture formed by these shavings and coolant is not treated promptly and effectively, it will directly affect the continuity and stability of the rough grinding process.

[0003] In terms of chip and coolant handling, most traditional rough grinding machines used for twist drill bit production simply guide the mixture into a single collection container through a simple feeding channel, lacking an effective solid-liquid separation structure. This results in long-term mixing and accumulation of chips and coolant. This design not only requires subsequent chip cleaning to be carried out by stopping the machine, but also prevents the coolant from being directly recycled and reused, leading to resource waste and increased environmental treatment costs. Although some grinding machines have added filter plates for separation, the filter plates and collection containers are mostly fixedly connected or use complex bolt fastening methods. When a large amount of chips accumulates on the filter plate surface and needs to be cleaned or replaced, multiple parts need to be disassembled with tools, which is cumbersome and time-consuming, seriously reducing the overall processing efficiency of the equipment. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide a rough grinding machine for producing twist drill bits, which solves the technical problem of inconvenience in cleaning in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a rough grinding machine for producing twist drill bits, comprising: a rough grinding machine body, a feeding groove formed at the bottom of the rough grinding machine body, a feeding pipe fixedly connected to the bottom of the rough grinding machine body, a fixing box fixedly connected to the outer wall of the feeding pipe, the fixing box being fixedly connected to the rough grinding machine body, a collection box snapped into the bottom of the fixing box, a filter plate slidably connected to the inner wall of the collection box, mounting grooves formed around the perimeter of the collection box, a fixing column fixedly connected to the bottom inner wall of the mounting groove, a fixing block slidably connected to the outer wall of the fixing column, the fixing block abutting against the bottom inner wall of the mounting groove, the fixing block being fixedly connected to the filter plate, and a pressure rod slidably connected to the mounting groove abutting against the top of the fixing block.

[0006] For example, in at least one embodiment of the present invention, a rough grinding machine for producing twist drill bits is provided, which further includes: a positioning groove is provided on the bottom inner wall of the fixed box, the inner wall of the positioning groove is adapted to the collection box, and the top inner wall of the positioning groove is fixedly connected to the pressure rod.

[0007] For example, in at least one embodiment of the present invention, a rough grinding machine for producing twist drill bits is provided, which further includes: a through groove is provided on the fixed block, and the through groove is adapted to the fixed column.

[0008] For example, in a rough grinding machine for producing twist drill bits provided in at least one embodiment of the present invention, a limiting groove is provided at the bottom of the pressure rod, and the limiting groove is adapted to the fixed column.

[0009] For example, in at least one embodiment of the present invention, a rough grinding machine for producing twist drill bits is provided, which further includes: symmetrically distributed buckles are slidably connected to the bottom of the fixed box, and the buckles are engaged with the collection box.

[0010] For example, in at least one embodiment of the present invention, a rough grinding machine for producing twist drill bits is provided, which further includes: symmetrically distributed slots on both sides of the collection box, the slots being adapted to buckles, and a drain pipe being fixedly connected to the bottom of the collection box.

[0011] For example, in at least one embodiment of the present invention, a rough grinding machine for producing twist drill bits is provided, which further includes: symmetrically distributed guide rods fixedly connected to both sides of the bottom of the fixed box, and the outer wall of the guide rods being slidably connected to the buckle.

[0012] For example, in at least one embodiment of the present invention, a rough grinding machine for producing twist drill bits is provided, which further includes: a spring sleeved on the outside of the guide rod, one end of the spring being fixedly connected to a buckle, and the other end of the spring being fixedly connected to a fixed box, and the spring being located on the side where the two buckles are close to each other.

[0013] For example, in at least one embodiment of the present invention, a rough grinding machine for producing twist drill bits is further comprising: a push rod fixedly connected to each of the two buckles on opposite sides, and the push rod being slidably connected to the fixed box.

[0014] For example, in at least one embodiment of the present invention, a coarse grinding machine for producing twist drill bits is provided, which further includes: a three-jaw chuck rotatably connected to the main body of the coarse grinding machine, a coarse grinding mechanism slidably connected to the main body of the coarse grinding machine on one side of the three-jaw chuck, and a transparent protective door slidably connected to the front side of the main body of the coarse grinding machine.

[0015] The beneficial effects of this utility model are as follows: 1. In this utility model, during cleaning, the coolant is discharged through the drain pipe for recycling. Pushing the push rod causes the push rod to move the buckle, thereby causing the buckle to lose its engagement with the collection box. The collection box can then be removed to clean the debris on the filter plate. When the collection box is removed, the pressure rod loses its limiting effect on the fixing block, making the fixing block and the filter plate detachable, which facilitates the cleaning of the filter plate. 2. In this utility model, during installation, the filter plate is pushed into the collection box, and the fixing block enters the installation groove. When the fixing block reaches the bottom of the installation groove, the fixing post extends out of the top of the fixing block through the through groove. Then, the collection box is pushed so that it enters the fixing box along the positioning groove. As the collection box rises, the pressure rod gradually approaches the fixing block along the installation groove. When the bottom of the collection box contacts the buckle, the collection box pushes the buckle to move, the spring contracts, and then the buckle extends out through the buckle groove. The spring resets the buckle, thereby making the buckle engage with the collection box. At this time, the pressure rod abuts against the fixing block, and the fixing post enters the limiting groove, thereby limiting the filter plate and facilitating installation.

[0024] like Figures 1 to 5As shown, this utility model provides a rough grinding machine for producing twist drill bits, including a rough grinding machine body 1. A feeding groove 9 is provided at the bottom of the rough grinding machine body 1. A feeding pipe 6 is fixedly connected to the bottom of the rough grinding machine body 1. A fixing box 5 is fixedly connected to the outer wall of the feeding pipe 6, and the fixing box 5 is fixedly connected to the rough grinding machine body 1. A collection box 7 is snapped into the bottom of the fixing box 5. A filter plate 17 is slidably connected to the inner wall of the collection box 7. Mounting grooves 21 are provided around the collection box 7. A fixing column 20 is fixedly connected to the bottom inner wall of the filter plate 17. A fixing block 18 is slidably connected to the outer wall of the fixing column 20. The fixing block 18 abuts against the bottom inner wall of the mounting groove 21. The fixing block 18 is fixedly connected to the filter plate 17. The top of the fixing block 18 abuts against a pressure rod 16 that is slidably connected to the mounting groove 21. The filter plate 17 is fixed after the collection box 7 is installed and fixed by the pressure rod 16 pressing against the fixing block 18.

[0025] The filter plate 17 is a 304 stainless steel mesh with a pore size of 0.2-0.5mm (resistant to coolant corrosion and high strength). The gap between the filter plate 17 and the inner wall of the collection box 7 is 0.05-0.1mm. A rubber sealing strip is provided on the edge of the filter plate 17 (to prevent side leakage).

[0026] In some examples, the bottom inner wall of the fixed box 5 is provided with a positioning groove 15, the inner wall of the positioning groove 15 is adapted to the collection box 7, and the top inner wall of the positioning groove 15 is fixedly connected to the pressure rod 16. The positioning groove 15 facilitates the installation of the collection box 7, so that after the collection box 7 rises along the positioning groove 15, the pressure rod 16 can enter the installation groove 21.

[0027] In some examples, the fixing block 18 has a through groove 19, and the through groove 19 is adapted to the fixing post 20. After the filter plate 17 is pushed into the collection box 7 through the through groove 19, the fixing post 20 can extend out of the top of the fixing block 18 through the through groove 19 when the fixing block 18 reaches the bottom of the mounting groove 21 along the mounting groove 21.

[0028] In some examples, a limiting groove 22 is provided at the bottom of the pressure rod 16, and the limiting groove 22 is adapted to the fixing post 20. When the pressure rod 16 abuts against the fixing block 18 after the collection box 7 is raised by the fixing post 20, the fixing post 20 can enter the limiting groove 22, so that the pressure rod 16 limits the fixing block 18.

[0029] In some examples, the bottom of the fixed box 5 is slidably connected with symmetrically distributed buckles 13, which engage with the collection box 7. The movement of the buckles 13 allows the collection box 7 to be limited when the buckles 13 return to their original position.

[0030] The buckle 13 has a protrusion width of 8-10mm and a height of 5-6mm. The corresponding size of the slot 14 is 0.1-0.2mm larger than the buckle (clearance fit) to ensure smooth engagement without looseness.

[0031] In some examples, the collection box 7 has symmetrically distributed slots 14 on both sides, which are adapted to the buckles 13. The bottom of the collection box 7 is fixedly connected to the drain pipe 10. The buckles 13 can easily enter through the slots 14, which facilitates the subsequent reset of the buckles 13 and their engagement with the collection box 7. The drain pipe 10 facilitates the recovery of coolant.

[0032] In some examples, symmetrically distributed guide rods 11 are fixedly connected to both sides of the bottom of the fixed box 5. The outer wall of the guide rod 11 is slidably connected to the buckle 13, and the movement of the buckle 13 is guided by the guide rod 11.

[0033] In some examples, a spring 12 is sleeved on the outside of the guide rod 11. One end of the spring 12 is fixedly connected to the buckle 13, and the other end of the spring 12 is fixedly connected to the fixed box 5. The spring 12 is located on the side where the two buckles 13 are close to each other. The spring 12 enables the buckles 13 to reset after movement, thereby realizing the buckle 13 and the collection box 7 engaging.

[0034] Spring 12 is made of carbon spring steel with an elastic modulus of 5-8 N / mm, a free length of 30-40 mm, and a working stroke of 10-15 mm (adapted to the movement distance of the buckle).

[0035] In some examples, push rods 8 are fixedly connected to the sides of the two clips 13 that are far apart from each other, and push rods 8 are slidably connected to the fixed box 5. When disassembling, the clips 13 can be moved by push rods 8.

[0036] In some examples, a three-jaw chuck 2 is rotatably connected to the main body 1 of the rough grinding machine. A rough grinding mechanism 3 is provided on one side of the three-jaw chuck 2 and is slidably connected to the main body 1 of the rough grinding machine. A transparent protective door 4 is slidably connected to the front side of the main body 1 of the rough grinding machine. The twist drill bit is clamped by the three-jaw chuck 2, the bit is rough ground by the rough grinding mechanism 3, and protected by the transparent protective door 4.

[0037] Working principle and usage process of this utility model: In this application, during use, the bar stock is clamped and fixed by the three-jaw chuck 2, and the bar stock is coarsely ground by the coarse grinding mechanism 3. During the processing, coolant is sprayed to cool it down. The coolant and debris are guided into the fixed box 5 through the feeding trough 9 and the feeding pipe 6, and then fall onto the filter plate 17 for collection. After being filtered by the filter plate 17, the coolant falls to the bottom of the collection box 7, which facilitates the collection of debris. In this application, during cleaning, the coolant is discharged through the drain pipe 10 for recycling. Pushing the push rod 8 causes the push rod 8 to move the buckle 13, thereby causing the buckle 13 to lose its engagement with the collection box 7. The collection box 7 can then be removed to clean the debris on the filter plate 17. When the collection box 7 is removed, the pressure rod 16 loses its limiting effect on the fixing block 18, making the fixing block 18 and the filter plate 17 detachable, which facilitates the cleaning of the filter plate 17. In actual use, the drain pipe 10 is equipped with a valve, which can be opened to drain the coolant. In this application, during installation, the filter plate 17 is pushed into the collection box 7, and the fixing block 18 enters the mounting groove 21. When the fixing block 18 reaches the bottom of the mounting groove 21, the fixing post 20 extends out of the top of the fixing block 18 through the through groove 19. Then, the collection box 7 is pushed so that it enters the fixing box 5 along the positioning groove 15. As the collection box 7 rises, the pressure rod 16 gradually approaches the fixing block 18 along the mounting groove 21. When the bottom of the collection box 7 contacts the buckle 13, the collection box 7 pushes the buckle 13 to move, the spring 12 contracts, and then the buckle 13 extends out through the slot 14. The spring 12 resets, causing the buckle 13 to reset, thereby making the buckle 13 engage with the collection box 7. At this time, the pressure rod 16 abuts against the fixing block 18, and the fixing post 20 enters the limiting groove 22, thereby limiting the filter plate 17 and facilitating installation.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
