Description

Technical Field

[0001] This invention belongs to the field of steel sheet processing technology, and particularly relates to a steel sheet chamfering device and a steel sheet processing machine. Background Technology

[0002] To remove burrs generated during machining, facilitate assembly, and prevent cuts from the ends of parts, chamfering is generally required. Steel sheets are typically chamfered using a small bench drill, with the chamfer depth controlled by a manual lever, leading to inconsistent results. When chamfering large steel sheets, it's difficult for the operator to lift the sheet by hand. Furthermore, debris often remains on the worktable during chamfering, causing issues such as workpiece over-proportioning and excessively deep holes. All of these factors negatively impact the efficiency and quality of steel sheet chamfering.

[0003] Therefore, designing a chamfering machine that offers good chamfer consistency, controllable chamfer depth, low skill requirements for personnel, and the ability to automatically chamfer steel sheets is a problem that urgently needs to be solved at this stage. Summary of the Invention

[0004] The purpose of this invention is to provide a steel sheet chamfering device, which aims to solve the technical problem in the prior art where the chamfering depth of steel sheets is controlled by the force of a manual swing lever, resulting in poor consistency after chamfering.

[0005] To achieve the above objectives, an embodiment of the present invention provides a steel sheet chamfering device, comprising a base with a feed chute located inside the base and extending one end to the outside of the base, and a grinding mechanism disposed inside the base and located on the side of the feed chute closer to the base. The grinding mechanism includes a plurality of grinding components arranged sequentially along the direction of the feed chute.

[0006] Furthermore, the grinding mechanism includes several bevel grinding components, a straight edge grinding component disposed at the rear end of the bevel grinding components, and a drive mechanism for driving the bevel grinding components and the straight edge grinding components to rotate.

[0007] Furthermore, the bevel grinding assembly includes a bevel drive shaft connected to the drive mechanism and located on the side of the feed chute near the machine base, and grinding discs oppositely disposed on the bevel drive shaft and located on both sides of the feed chute. The straight edge grinding assembly includes a straight edge drive shaft connected to the drive mechanism and located on the side of the feed chute near the machine base, and a grinding roller sleeved on the straight edge drive shaft, with a steel sheet passing between the two grinding discs.

[0008] Furthermore, the bevel grinding assembly also includes a threaded sleeve fitted onto and threadedly connected to the bevel drive shaft, with a grinding disc located at the end of the threaded sleeve near the feed groove. A fixed sleeve extends from the end of the threaded sleeve away from the feed groove, with several fixed screw holes on the fixed sleeve. A fixed silicone sleeve is located on the inner side of the fixed sleeve, and fixed screws connect to the fixed screw holes to drive the fixed silicone sleeve to abut against the bevel drive shaft.

[0009] Furthermore, the upper end of the inclined drive shaft is provided with a scale for adjusting the position of the threaded sleeve.

[0010] Furthermore, a transport mechanism is also provided on the base, which is located on the material feed chute and is used to transport steel sheets through each grinding component in sequence.

[0011] Furthermore, the transport mechanism is a conveyor belt, which is also equipped with several limit blocks. The limit blocks are used to limit the steel plates on the conveyor belt.

[0012] Furthermore, the machine base is also provided with several water injection holes, which are located above the material trough. The bottom of the machine base is provided with a return mechanism, which includes a water collection tank located at the bottom of the machine base, a return pipe communicating with the water injection holes, and a return pump communicating with the return pipe and the water collection tank.

[0013] Furthermore, a steel sheet processing machine includes four steel sheet chamfering devices arranged end-to-end. It also includes a conveying mechanism for sequentially conveying steel sheets through each of the steel sheet chamfering devices.

[0014] The steel sheet chamfering equipment provided in this invention provides at least one of the following technical effects: The steel sheet is placed in the feed trough and positioned at the end abutting the feed trough near the grinding mechanism. The steel sheet is pushed, causing it to pass sequentially through the grinding components, which grind the ends of the steel sheet sequentially, thus completing the chamfering of the steel sheet ends. Placing the steel sheet in the feed trough and pushing it saves the operator's effort, eliminating the need to lift the steel sheet to align it with the bench drill for chamfering. Passing through multiple grinding components sequentially allows for the steel sheet to be ground sequentially, avoiding the unevenness caused by grinding the steel sheet in one go.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0025] In one embodiment of the present invention, reference is made to... Figures 1-4 As shown, a steel sheet chamfering device is provided, including a base 10 with a feed groove 11, the feed groove 11 being located inside the base 10 and extending to the outside of the base 10 at one end, and a grinding mechanism 20 disposed inside the base 10 and located on the side of the feed groove 11 near the base 10. The grinding mechanism 20 includes a plurality of grinding components 21 arranged sequentially along the direction of the feed groove 11. In this embodiment, a steel sheet is placed in the feed groove 11 and located at the end of the feed groove 11 near the grinding mechanism 20. The steel sheet is pushed so that it passes through the grinding components 21 sequentially, and the grinding components 21 grind the ends of the steel sheet sequentially to complete the chamfering of the steel sheet ends. Placing the steel sheet in the feed groove 11 and pushing the steel sheet to move it saves the operator's effort, as it does not require lifting the steel sheet to align with a bench drill for chamfering. Passing through multiple grinding components 21 sequentially allows the steel sheet to be ground sequentially, avoiding the unevenness of the ground ends caused by grinding the steel sheet all at once.

[0026] Specifically, refer to Figures 1-4 As shown, the grinding mechanism 20 includes several bevel grinding components 30, a straight-edge grinding component 40 disposed at the rear end of the bevel grinding components 30, and a drive mechanism for driving the bevel grinding components 30 and the straight-edge grinding components 40 to rotate. In this embodiment, the bevel grinding components 30 perform preliminary grinding on the end of the steel sheet, making the end of the steel sheet triangular. Subsequently, the straight-edge grinding components 40 grind the end of the steel sheet after the bevel grinding components 30 have ground it again, smoothing the sharp corners of the triangle and completing the chamfer. The steel sheet is ground sequentially by the bevel grinding components 30 and the straight-edge grinding components 40 to avoid the steel sheet being ground in one go, which would result in an uneven ground end.

[0027] More specifically, see reference Figures 1-4 As shown, there are two bevel grinding components 30, which grind the ends of the steel sheet at 30 degrees and 45 degrees at a time.

[0028] Specifically, refer to Figures 1-4As shown, the bevel grinding assembly 30 includes a bevel drive shaft 31 connected to the drive mechanism and located on the side of the feed groove 11 near the machine base 10, and grinding discs 32 oppositely disposed on the bevel drive shaft 31 and located on both sides of the feed groove 11. The straight edge grinding assembly 40 includes a straight edge drive shaft 41 connected to the drive mechanism and located on the side of the feed groove 11 near the machine base 10, and a grinding roller sleeved on the straight edge drive shaft 41. The steel sheet passes between the two grinding discs. In this embodiment, the steel sheet is placed in the feed groove 11, passes through several bevel grinding assemblies 30 in sequence, and finally passes through the straight edge grinding assembly 40. The steel sheet passes between the two grinding discs 32, and the two grinding discs 32 grind the upper and lower surfaces of the steel sheet end. Then it passes through the grinding roller, and the tip of the steel sheet is smoothed by the grinding roller to complete the chamfer. Passing through multiple grinding assemblies 21 in sequence can grind the steel sheet sequentially, avoiding the problem of the grinding end being rough due to grinding the steel sheet in one go.

[0029] More specifically, see reference Figures 1-4 As shown, the included angles between the abrasive disc wheel 32 and the feed groove 11 are 30 degrees and 45 degrees, respectively.

[0030] Specifically, refer to Figures 1-4 As shown, the bevel grinding assembly 30 also includes a threaded sleeve 33 sleeved on and threadedly connected to the bevel drive shaft 31. The grinding disc 32 is located at the end of the threaded sleeve 33 near the feed groove 11. A fixed sleeve 34 extends from the end of the threaded sleeve 33 away from the feed groove 11. The fixed sleeve 34 is provided with several fixed screw holes 35. A fixed silicone sleeve 36 is provided on the inner side of the fixed sleeve 34. The fixing screw is connected to the fixed screw hole 35 to drive the fixed silicone sleeve 36 to abut against the bevel drive shaft 31. In this embodiment, the position of the threaded sleeve 33 on the inclined drive shaft 31 is adjusted by rotating the threaded sleeve 33. The fixing screw is screwed into the fixing screw hole 35. The fixing screw applies pressure to the fixing silicone sleeve 36, so that the fixing silicone sleeve 36 is pressed tightly on the inclined drive shaft 31, and the grinding disc 32 rotates with the inclined drive shaft 31. The position of the grinding disc 32 can be adjusted, and wear of the grinding disc 32 after repeated use can be avoided, which would lead to inaccurate grinding by the grinding disc 32.

[0031] Specifically, refer to Figures 1-4 As shown, the upper end of the inclined drive shaft 31 is provided with a scale for adjusting the position of the threaded sleeve 33. In this embodiment, the upper end of the inclined drive shaft 31 is provided with a scale for adjusting the position of the threaded sleeve 33. The relative position of the threaded sleeve 33 and the inclined drive shaft 31 can be adjusted according to the deviation of the processed steel sheet. Adjustment is more convenient and precise by adjusting according to the scale on the inclined drive shaft 31.

[0032] Specifically, refer to Figures 1-4As shown, the base 10 is also equipped with a transport mechanism 15, which is located on the feed chute 11. The transport mechanism 15 is used to transport the steel sheet through each grinding assembly 21 in sequence. In this embodiment, the transport mechanism 15 is used to transport the steel sheet through each grinding assembly 21 in sequence without manual movement. At the same time, the transport mechanism 15 can drive the steel sheet through the grinding assembly 21 at a uniform speed, avoiding excessive speed from affecting the grinding accuracy.

[0033] Specifically, refer to Figures 1-4 As shown, the transport mechanism 15 is a conveyor belt 12, and the conveyor belt 12 is also provided with several limiting blocks 13. The limiting blocks 13 are used to limit the steel sheets on the conveyor belt 12. In this embodiment, the conveyor belt 12 is also provided with several limiting blocks 13. The limiting blocks 13 are used to limit the steel sheets on the conveyor belt 12 to prevent the steel sheets from slipping on the conveyor belt 12 during the grinding process, which would affect the subsequent processing of the steel sheets.

[0034] Specifically, refer to Figures 1-4 As shown, the transport mechanism 15 can also be a roller.

[0035] Specifically, refer to Figures 1-4 As shown, the machine base 10 is also provided with several water injection holes 14, which are located above the material feed trough 11. A return mechanism 50 is provided at the bottom of the machine base 10. The return mechanism 50 includes a water collection tank 51 located at the bottom of the machine base 10, a return pipe 52 communicating with the water injection holes 14, and a return pump 53 connecting the return pipe 52 and the water collection tank 51. In this embodiment, the water injection holes 14 continuously inject water into the material feed trough 11. The water flows along the machine base 10 into the water collection tank 51, and the water in the water collection tank 51 is transferred back to the water injection holes 14 through the return pump 53 and the return pipe 52, forming a water circulation. This cools the polished steel sheet and effectively cleans the debris remaining in the material feed trough 11.

[0036] Specifically, refer to Figures 1-4 As shown, a steel sheet processing machine includes four steel sheet chamfering devices arranged end-to-end. It also includes a conveying mechanism for sequentially transporting steel sheets through each chamfering device. In this embodiment, the conveying mechanism transports the steel sheets sequentially through the chamfering devices, which then sequentially grind all four sides of the steel sheet without rotating it, achieving full automation.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
