Description

Technical Field

[0001] This application relates to the field of broaching machine scrap removal, and more specifically, to a scrap removal device based on a broaching machine. Background Technology

[0002] A horizontal broaching machine is a device that uses broaches to cut keyways in annular materials such as gears and worm gears.

[0003] The existing horizontal broaching machine includes a frame 1, a broach 3, a broach die 2, and a hydraulic cylinder 4. The frame 1 has a receiving cavity 11. The broach die 2 and the hydraulic cylinder 4 are mounted on the frame 1. The broach die 2 has a guide groove for the broach 3 to pass through. A push plate 41 is fixedly connected to the output end of the hydraulic cylinder 4. The push plate 41 has a clamping fixture 411 for holding the broach 3. The output end of the hydraulic cylinder 4, the push plate 41, and the clamping fixture 411 are all located within the receiving cavity 11. During machining, the output end of the hydraulic cylinder 4 drives the push plate 41, the clamping fixture 411, and the broach 3 to move away from the broach die 2 within the receiving cavity 11 to machine the workpiece.

[0004] However, during the machining process, when the broach comes into contact with the workpiece, the broach will push some of the iron filings generated during machining into the receiving cavity along the guide direction of the guide groove. When the iron filings fall to the bottom of the receiving cavity, it is not convenient for the worker to clean the iron filings in the receiving cavity. Utility Model Content

[0030] Reference Figure 1-4 ,

[0031] A scrap metal cleaning device based on a broaching machine includes: a frame 1 and a broaching die 2; the frame 1 forms a receiving cavity 11, and the broaching die 2 is disposed on the frame 1; the scrap metal cleaning device includes: a drive component 5 and a scraper 6; the drive component 5 is a hydraulic cylinder or a pneumatic cylinder, preferably a hydraulic cylinder in this embodiment. The drive component 5 and the scraper 6 are disposed in the receiving cavity 11; the frame 1 forms a discharge port 12 for scrap metal to be discharged from the receiving cavity 11; the discharge port 12 is located below the broaching die 2; the scraper 6 contacts the bottom surface of the receiving cavity 11; the drive component 5 is used to drive the scraper 6 to move towards or away from the discharge port 12 on the bottom surface of the receiving cavity 11. After the workpiece is processed, the drive unit 5 can push the scraper 6 to move towards the discharge port 12 from the bottom of the receiving cavity 11. The scraper 6 pushes the iron filings that have fallen to the bottom of the receiving cavity 11 to move, so that the iron filings are discharged from the discharge port 12, thereby realizing automatic cleaning of iron filings without manual intervention.

[0032] Specifically, the bottom surface of the receiving cavity 11 forms an inclined surface 111; one end of the inclined surface 111 extends to the discharge port 12; the scraper 6 includes a moving block 61 and a scraper 62; the scraper 62 is made of rubber. The moving block 61 is fixedly mounted on the output end of the driving member 5, and a gap is formed between the moving block 61 and the bottom surface of the receiving cavity 11 to prevent the moving block 61 from contacting the bottom surface of the receiving cavity 11. If the moving block 61 contacts the bottom surface of the receiving cavity 11, the moving block 61 will be affected by friction when the driving member 5 pushes the moving block 61 to move, which will cause damage to the moving block 61. The moving block 61 forms a receiving cavity 11 chamber to accommodate the scraper 62; the scraper 62 is used to contact the bottom surface of the receiving cavity 11 and the inclined surface 111 to ensure that the scraper 62 can clean the iron filings on the bottom surface of the receiving cavity 11 and the inclined surface 111. The receiving cavity 11 is designed to both accommodate the scraper 62 and guide it. When the drive unit 5 pushes the moving block 61 and the scraper 62 toward the discharge port 12, the scraper 62 will first contact the bottom surface of the receiving cavity 11. Once the moving block 61 is above the inclined surface 111, the scraper 62 will move within the receiving cavity 11 due to gravity, and will then contact the inclined surface 111. When the output end of the drive unit 5 pushes the moving block 61 to its furthest point, part of the scraper 62 will still remain within the receiving cavity 11. As the drive unit 5 moves the moving block 61 and the scraper 62 away from the discharge port 12, the scraper 62 will slowly retract back into the receiving cavity 11 along the inclined direction of the inclined surface 111.

[0033] Specifically, the iron filings cleaning device further includes an iron filings collection box; the iron filings collection box is located below the discharge port 12. The scraper 62 pushes the iron filings that fall onto the bottom surface and inclined surface 111 of the receiving cavity 11, so that the iron filings enter the iron filings collection box through the discharge port 12.

[0034] Specifically, the scraper 6 further includes: a guide rod 63 and a fixing plate 64; both the guide rod 63 and the fixing plate 64 are provided in two sets. A first straight hole 611 is formed at one end of the moving block 61 facing away from the bottom surface of the receiving cavity 11; the fixing plate 64 is disposed above the moving block 61; the fixing plate 64 forms a second straight hole 641 that coincides with the center line of the first straight hole 611; the guide rod 63 is disposed within the first straight hole 611 and the second straight hole 641, and one end of the guide rod 63 is fixedly connected to the scraper 62. The guide rod 63 and the fixing plate 64 further guide the scraper 62, preventing the scraper 62 from failing to return to the receiving cavity 11 when the driving member 5 moves the moving block 61 and the scraper 62 away from the discharge port 12.

[0035] Specifically, a spring 65 is provided between the fixing plate 64 and the scraper 62; the spring 65 is sleeved on the guide rod 63. The spring 65 is provided to provide elastic compensation. When the scraper 62 is located in the receiving cavity 11, the spring 65 will apply pressure in the direction of the scraper 62, so that the scraper 62 can fully contact the bottom surface of the receiving cavity 11. This prevents the scraper 62 from getting stuck between the scraper 62 and the bottom surface of the receiving cavity 11 during the process of pushing the scraper 62 to move, thus preventing the scraper 62 from failing to contact the bottom surface of the receiving cavity 11.

[0036] Specifically, during the processing of the workpiece, to prevent the temperature between the workpiece and the broach 3 from becoming too high, the worker usually uses coolant to cool the broach 3 and the workpiece. When the broach 3 processes the workpiece, some coolant is also carried into the receiving cavity 11. The moving block 61 forms multiple drainage holes 612 at the end opposite to the driving member 5. The drainage direction of the drainage holes 612 is inclined or perpendicular to the inclined surface 111, so that before the scraper 6 comes into contact with the iron filings, the water flow can first wash away the small iron filings and coolant on the bottom surface of the receiving cavity 11 and the inclined surface 111, and then the scraper 62 cleans the larger iron filings on the bottom surface of the receiving cavity 11 and the inclined surface 111. In this embodiment, the drainage direction of the drainage holes 612 is inclined to the inclined surface 111. The iron filings cleaning device also includes: a centrifugal pump 7 and a first connecting pipe 8; one end of the first connecting pipe 8 is connected to the output end of the centrifugal pump 7, and the other end of the first connecting pipe 8 is connected to the drainage hole 612. Workflow: After the workpiece is processed, the drive unit 5 pushes the moving block 61 and the scraper 62 to move on the bottom surface and inclined surface 111 of the receiving cavity 11. At the same time, the centrifugal pump 7 injects water into the first connecting pipe 8. The water in the first connecting pipe 8 is discharged through the drain hole 612 onto the bottom surface and inclined surface 111 of the receiving cavity 11. Then the scraper 62 can perform secondary cleaning on these areas washed by the water flow.

[0037] Specifically, the output end of the drive unit 5 pushes the moving block 61 and the scraper 62 to move towards the discharge port 12. When the moving block 61 and the scraper 62 move to the farthest distance, a gap is formed between the moving block 61 and the discharge port 12. The gap is located in the receiving cavity 11 so that the scraper 62 located in the receiving cavity 11 can always be in contact with the inclined surface 111, preventing the scraper 62 from falling out of the receiving cavity 11 and also preventing the moving block 61 from hitting the frame 1.

[0038] Specifically, the movable block 61 has multiple vent holes 613 formed at the end opposite to the driving member 5; the venting direction of the vent holes 613 is inclined or perpendicular to the inclined surface 111; in this embodiment, the venting direction of the vent holes 613 is inclined relative to the inclined surface 111. The iron filings cleaning device also includes: an air pump 9 and a second connecting pipe 10; one end of the second connecting pipe 10 is connected to the output end of the air pump 9, and the other end of the second connecting pipe 10 is connected to the vent holes 613. The gap formed between the movable block 61 and the discharge port 12 may prevent iron filings on the inclined surface 111 from falling into the iron filings collection box, therefore, vent holes 613 are provided in this embodiment. The venting direction of the vent holes 613 is inclined relative to the inclined surface 111. When the driving member 5 pushes the movable block 61 and the scraper 62 to move to the farthest distance towards the discharge port 12, the gas discharged from the vent holes can allow the iron filings to enter the iron filings collection box through the discharge port 12.
