Description

Technical Field

[0001] The present invention relates to the technical field of chamfering processing, and particularly to a chamfering machine and a chamfering processing method. Background Art

[0002] Currently, the chamfering processing of plate-shaped parts is generally completed manually or with the aid of a chamfering machine. The chamfering machines in the prior art generally include a frame and a chamfering roller set. The chamfering roller set includes two chamfering rollers arranged at intervals. The chamfering rollers can rotate relative to the frame, and the outer peripheral wall of the chamfering roller is provided with a boss. The bosses of the two chamfering rollers in the same chamfering roller set are arranged oppositely. The side wall of the boss is a shoulder. The plate-shaped part can be conveyed between the two chamfering rollers in the same chamfering roller set, so that along the thickness direction of the plate-shaped part, the shoulders of the two chamfering rollers simultaneously squeeze both ends of the plate-shaped part to complete chamfering.

[0003] The thickness of the thin plate that the above-mentioned chamfering machine can chamfer depends on the minimum distance between the shoulders of the two chamfering rollers. The distance between the shoulder of the chamfering roller and the edge of the chamfering roller is generally not less than 5 mm. Therefore, the minimum distance between the shoulders of the two chamfering rollers is not less than 10 mm. That is, the chamfering roller set can only process plate-shaped parts with a thickness of more than 10 mm and cannot chamfer thin plate parts with a thickness of less than 10 mm (such as an 8-mm strip panel part). If the distance between the shoulder of the chamfering roller and the edge of the chamfering roller is set to less than 5 mm (such as 4 mm), the structural strength of the chamfering roller will be reduced. At this time, the chamfering roller is prone to plastic deformation, affecting the chamfering processing quality and damaging the chamfering wheel. In severe cases, it may even cause the boss to burst. Summary of the Invention

The chamfering machine further includes a driving assembly, and the driving assembly is used to drive the two chamfering wheels of the chamfering wheel set to rotate relative to the frame, so as to drive the workpiece to move along its front-rear direction, and cold-press both sides of the workpiece through the two chamfering wheels. The front-rear direction, left-right direction and thickness direction of the workpiece are perpendicular to each other in pairs.

[0018] The frame includes a support seat for supporting on the ground and a mounting frame slidably arranged on the support seat. One of the chamfering wheels of the chamfering wheel set is arranged on the support seat, and the other chamfering wheel is arranged on the mounting frame. The chamfering machine further includes a mounting frame driving member, and the mounting frame driving member is used to drive the mounting frame to move, so as to drive the two chamfering wheels to approach or separate from each other.

[0019] The chamfering method includes:

[0020] S100: Convey the workpiece so that the front end of the workpiece is located between the two chamfering wheels.

[0021] S200: Drive the two chamfering wheels to approach each other through the mounting frame driving member, so that the two chamfering wheels are respectively in close contact with both sides of the workpiece, and drive the two chamfering wheels to rotate through the driving assembly to drive the workpiece to move.

[0022] As a preferred solution of the chamfering method, in the chamfering machine, two chamfering wheel sets are provided, and the two chamfering wheel sets are arranged at intervals along the front-rear direction of the workpiece. Among them, the chamfering wheel set located upstream is the first chamfering wheel set, and the chamfering wheel set located downstream is the second chamfering wheel set.

[0023] In the chamfering method,

[0024] In step S100, convey the workpiece so that the front end of the workpiece is located between the two chamfering wheels of the first chamfering wheel set.

[0029] S600: Continue to convey the workpiece to be processed so that the front end of the workpiece to be processed is located between the two chamfering wheels of the second chamfering wheel set;

[0030] S600: Drive the two chamfering wheels of the second chamfering wheel set to approach each other through the mounting frame driving member, so that the two chamfering wheels of the second chamfering wheel set are respectively in close contact with both sides of the workpiece to be processed, and drive the two chamfering wheels of the second chamfering wheel set to rotate through the driving assembly to drive the workpiece to be processed to move.

[0031] The beneficial effects of the present invention are:

[0032] The present invention provides a chamfering machine for chamfering a workpiece to be processed in the shape of a plate, and includes a frame and a chamfering wheel set. The frame is used to support on the ground; the chamfering wheel set includes two chamfering wheels rotatably arranged on the frame. Along the left-right direction of the workpiece to be processed, the two chamfering wheels are respectively located on both sides of the workpiece to be processed; the chamfering wheel has a groove. Along the thickness direction of the workpiece to be processed, the two side walls of the groove can respectively contact the two side edges of the workpiece to be processed to perform cold pressing on both sides of the workpiece to be processed. The left-right direction of the workpiece to be processed is perpendicular to the thickness direction. In this chamfering machine, the two side walls of the groove respectively contact the two side edges of the workpiece to be processed to perform cold pressing on both sides of the workpiece to be processed, so that the chamfering processing of the workpiece to be processed can be carried out. The chamfering wheel set includes two chamfering wheels rotatably arranged on the frame, and the chamfering processing can be simultaneously carried out on both sides of the workpiece to be processed along its left-right direction. In addition, the above chamfering processing is completed by cold pressing through the two side walls of the groove. Therefore, the maximum thickness of the workpiece to be processed that can be processed depends on the distance between the two side walls of the groove, and the minimum distance between the two side walls of the groove can be set to be relatively small, for example, it can be set to 8 mm, and it does not affect the overall structural strength of the chamfering wheel, so that the chamfering machine is suitable for workpieces to be processed of thin plate type.

[0033] The present invention also provides a chamfering method, which is implemented by the above-mentioned chamfering machine. In the chamfering method, the workpiece to be processed is conveyed so that the front end of the workpiece to be processed is located between two chamfering wheels; the two chamfering wheels are driven to approach each other by the mounting frame driving member, so that the two chamfering wheels are respectively in close contact with both sides of the workpiece to be processed, and the two chamfering wheels are driven to rotate by the driving assembly to drive the workpiece to be processed to move. Thus, while chamfering both the left and right sides of the workpiece to be processed by the two chamfering wheels at the same time, the workpiece to be processed can also be driven to move to achieve automatic chamfering processing.

[0052] Embodiment 1

[0053] At present, the thickness of the thin plate that the chamfering machine can chamfer depends on the minimum distance between the shoulders of the two chamfering rollers. The distance between the shoulder of the chamfering roller and the edge of the chamfering roller is generally not less than 5 mm. Therefore, the minimum distance between the shoulders of the two chamfering rollers is not less than 10 mm. That is, the chamfering roller group can only process plate-shaped parts with a thickness of more than 10 mm and cannot chamfer thin plate parts with a thickness of less than 10 mm (such as 8 mm strip panel parts). If the distance between the shoulder of the chamfering roller and the edge of the chamfering roller is set to less than 5 mm (such as 4 mm), the structural strength of the chamfering roller will be reduced. At this time, the chamfering roller is prone to plastic deformation, affecting the chamfering quality, damaging the chamfering wheel, and even causing the boss to burst seriously in severe cases.

[0054] In view of the above problems, this embodiment provides a chamfering machine to solve the problem that the existing chamfering machine cannot chamfer thin plate parts with a thickness of less than 10 mm, and it can be used in the field of chamfering processing technology.

[0055] Referring to Figures 1-5 , the chamfering machine is used to chamfer a plate-shaped workpiece to be processed, and includes a frame 1 and a chamfering wheel group 2. The frame 1 is used to support on the ground; the chamfering wheel group 2 includes two chamfering wheels 21 rotatably arranged on the frame 1. Along the left-right direction of the workpiece to be processed (i.e., the CD direction in Figure 4 ), the two chamfering wheels 21 are respectively located on both sides of the workpiece to be processed; the chamfering wheel 21 has a groove 211. Along the thickness direction of the workpiece to be processed (i.e., the EF direction in Figure 1 and Figure 3 ), the two side walls of the groove 211 can respectively contact the two side edges of the workpiece to be processed to cold-press the two sides of the workpiece to be processed. The left-right direction of the workpiece to be processed is perpendicular to the thickness direction. In this chamfering machine, the two side walls of the groove 211 respectively contact the two side edges of the workpiece to be processed to cold-press the two sides of the workpiece to be processed, so as to chamfer the workpiece to be processed. The chamfering wheel group 2 includes two chamfering wheels 21 rotatably arranged on the frame 1, and can chamfer the two sides of the workpiece to be processed along its left-right direction at the same time. In addition, the above chamfering process is completed by cold-pressing the workpiece to be processed by the two side walls of the groove 211. Therefore, the maximum thickness of the workpiece to be processed that it can process depends on the distance between the two side walls of the groove 211, and the minimum distance between the two side walls of the groove 211 can be set smaller, for example, it can be set to less than 10 mm, and it does not affect the overall structural strength of the chamfering wheel 21, so that the chamfering machine is suitable for workpieces to be processed of thin plate type with a thickness of less than 10 mm. In this embodiment, specifically, the minimum distance between the two side walls of the groove 211 can be set to 8 mm or 6 mm to achieve chamfering of workpieces to be processed with corresponding thicknesses.

[0056] Continue to refer to Figures 1-5, there are two chamfering wheel sets 2, which are arranged at intervals in the front-back direction of the workpiece to be processed. Thus, the workpiece to be processed can be chamfered successively by the two chamfering wheel sets 2 to improve the chamfering effect.

[0057] Continue to refer to Figures 1-5 , the chamfering machine further includes a driving assembly 3. The driving assembly 3 is used to drive the two chamfering wheels 21 of the chamfering wheel set 2 to rotate relative to the frame 1, so as to drive the workpiece to be processed to move in its front-back direction (i.e., Figure 1 , Figures 3-5 the AB direction in Figure 1 , Figures 3-5 ), specifically, in the direction from back to front (i.e.,

[0058] the direction from B to A in

[0059] ), and cold-press both sides of the workpiece to be processed through the two chamfering wheels 21. The front-back direction, left-right direction and thickness direction of the workpiece to be processed are perpendicular to each other in pairs. Thus, while chamfering both left and right sides of the workpiece to be processed through the two chamfering wheels 21, the workpiece to be processed can also be driven to move to achieve automatic chamfering. Figures 1-5 , the driving assembly 3 includes a driving motor 31 and a transmission member 32 connected to the output end of the driving motor 31. A rotating shaft 22 is fixedly arranged on the chamfering wheel 21, and the rotating shaft 22 is rotatably arranged on the frame 1. Specifically, a bearing 221 can be arranged between the rotating shaft 22 and the frame 1. The outer ring of the bearing 221 is connected to the frame 1, and the inner ring is connected to the rotating shaft 22. The transmission member 32 is in transmission connection with the rotating shaft 22 of one of the chamfering wheels 21, so as to drive one of the chamfering wheels 21 to rotate. When cold-pressing both sides of the workpiece to be processed through the two side walls of the groove 211, the two side walls of the groove 211 need to press the workpiece to be processed, and there is no relative sliding between the chamfering wheel 21 and the workpiece to be processed. Therefore, when only one of the chamfering wheels 21 is driven to rotate at this time, the other chamfering wheel 21 can be driven to rotate simultaneously through the workpiece to be processed. In other embodiments, the transmission member 32 can also be in transmission connection with the rotating shafts 22 of the two chamfering wheels 21 at the same time, so as to drive the two chamfering wheels 21 to rotate simultaneously.

[0060] Continue to refer to Figures 1-5 , the transmission member 32 includes a transmission rod 321 rotatably arranged on the frame 1. Among them, the extending direction of the transmission rod 321 is perpendicular to the extending direction of the rotating shaft 22. The transmission rod 321 is connected to the output end of the driving motor 31 through a gear set 322, and is connected to the rotating shafts 22 of the two chamfering wheel sets 2 respectively through two bevel gear sets 323.

[0061] Continue to refer to Figures 1-5, the frame 1 includes a support base 11 for supporting on the ground and a mounting frame 12 slidably arranged on the support base 11. Optionally, the support base 11 is provided with a guide rod 13 extending in the left-right direction of the workpiece to be processed, and the mounting frame 12 is slidably arranged on the guide rod 13. One chamfering wheel 21 of the chamfering wheel group 2 is arranged on the support base 11, and the other chamfering wheel 21 is arranged on the mounting frame 12. The chamfering machine further includes a mounting frame driving member 4, and the mounting frame driving member 4 is used to drive the mounting frame 12 to move, so as to drive the two chamfering wheels 21 to approach or move away from each other, so that the two chamfering wheels 21 clamp the workpiece to be processed, or release the clamping of the chamfering wheels 21. In this embodiment, the mounting frame driving member 4 is a mounting frame driving oil cylinder, and the mounting frame driving oil cylinder has a fixed end 41 and a telescopic end 42 that can reciprocally extend relative to the fixed end 41 in the left-right direction of the workpiece to be processed. One of the fixed end 41 and the telescopic end 42 is fixedly arranged on the support base 11, and the other is fixedly arranged on the mounting frame 12. Specifically in this embodiment, the fixed end 41 is fixedly arranged on the support base 11, and the telescopic end 42 is fixedly arranged on the mounting frame 12. Optionally, there are two mounting frame driving members 4, and the two mounting frame driving members 4 are respectively located at the front and rear ends of the frame 1, so that the mounting frame 12 can slide smoothly relative to the support base 11.

[0062] Continue to refer to Figures 1-5 , the chamfering machine further includes a guide wheel group 5. The guide wheel group 5 includes two guide wheels 51 that can rotate relative to the frame 1. The two guide wheels 51 are respectively located on the left and right sides of the workpiece to be processed, and can respectively contact the two sides of the workpiece to be processed, so as to guide the movement direction of the workpiece to be processed and prevent the movement direction of the workpiece to be processed from deviating. Optionally, there are multiple guide wheel groups 5, and along the front-rear direction of the workpiece to be processed, the multiple guide wheel groups 5 are arranged at intervals in sequence.

[0063] Continue to refer to Figures 1-5 , the guide wheel 51 is provided with a guide wheel adjusting mechanism 52. The guide wheel adjusting mechanism 52 is used to adjust the position of the guide wheel 51 relative to the frame 1, so that the two guide wheels 51 of the guide wheel group 5 approach or move away from each other, so that the distance between the two guide wheels 51 of the guide wheel group 5 matches the length of the workpiece to be processed in its left-right direction. Specifically, the guide wheel 51 is rotatably connected to the guide wheel mounting member 53, and the guide wheel mounting member 53 is slidably arranged on the frame 1 in the left-right direction of the workpiece to be processed. The guide wheel adjusting mechanism 52 includes an adjusting bolt, and the adjusting bolt is rotatably arranged on the frame 1 and is threadedly connected to the guide wheel mounting member 53. Thus, by rotating the adjusting bolt, the guide wheel mounting member 53 can be driven to slide relative to the frame 1, so as to drive the guide wheel 51 arranged on the guide wheel mounting member 53 to move, so that the two guide wheels 51 of the guide wheel group 5 approach or move away from each other. Optionally, an adjusting handle 521 is fixedly arranged on the adjusting bolt, and the user can drive the adjusting bolt to rotate by rotating the adjusting handle 521, so as to control the position of the corresponding guide wheel 51.

[0064] Example Two

[0065] This embodiment provides a chamfering method, which is implemented by the chamfering machine in the above embodiment.

[0066] Refer to Figure 6 , and the chamfering method includes the following steps.

[0067] S100: Convey the workpiece to be processed so that the front end of the workpiece to be processed is located between the two chamfering wheels 21.

[0068] Since the workpiece to be processed has not contacted the chamfering wheels 21 at this time and cannot be driven by the chamfering wheels 21, the workpiece to be processed can be conveyed through structures such as conveying rollers.

[0069] S200: Drive the two chamfering wheels 21 to approach each other through the mounting frame driving member 4 so that the two chamfering wheels 21 are respectively in close contact with both sides of the workpiece to be processed, and drive the two chamfering wheels 21 to rotate through the driving assembly 3 to drive the workpiece to be processed to move.

[0070] In this chamfering method, the workpiece to be processed is conveyed so that the front end of the workpiece to be processed is located between the two chamfering wheels 21; the two chamfering wheels 21 are driven to approach each other through the mounting frame driving member 4 so that the two chamfering wheels 21 are respectively in close contact with both sides of the workpiece to be processed, and the two chamfering wheels 21 are driven to rotate through the driving assembly 3 to drive the workpiece to be processed to move, so that while chamfering the left and right sides of the workpiece to be processed simultaneously by the two chamfering wheels 21, the workpiece to be processed can also be driven to move to realize automatic chamfering processing.

[0071] Optionally, the chamfering machine is provided with two chamfering wheel sets 2, wherein the chamfering wheel set 2 located upstream is the first chamfering wheel set, and the chamfering wheel set 2 located downstream is the second chamfering wheel set. In addition, the chamfering machine is also provided with a first detection structure 61, a second detection structure 62 and a third detection structure 63. Along the movement direction of the workpiece to be processed (i.e., the direction from B to A in the figure), the first detection structure 61, the first chamfering wheel set, the second detection structure 62, the second chamfering wheel set and the third detection structure 63 are arranged in sequence. Among them, the first detection structure 61, the second detection structure 62 and the third detection structure 63 are used to detect whether the workpiece to be processed moves in place. Specifically, they can be infrared detection structures or laser detection structures, and one end is a transmitter and the other end is a receiver. The receiver is used to receive the infrared rays or laser emitted by the transmitter. When the workpiece to be detected moves between the transmitter and the receiver, it blocks the infrared rays or laser from entering the receiver, thereby determining that the workpiece to be processed has moved in place. The specific detection principle and related control methods are already relatively conventional technologies in this field and will not be elaborated here.

[0072] Refer to Figure 7, in this chamfering method, in step S100, the workpiece to be machined is conveyed so that the front end of the workpiece to be machined is located between the two chamfering wheels 21 of the first chamfering wheel set.

[0073] Specifically, before the workpiece to be machined contacts the chamfering wheel 21, its conveying speed is consistent. Therefore, when the first detection structure 61 detects that the workpiece to be machined has been conveyed between the transmitter and the receiver of the first detection structure 61, it can be determined that the front end of the workpiece to be machined is located between the two chamfering wheels 21 of the first chamfering wheel set after a first set time.

[0074] In step S200, the mounting bracket driving member 4 drives the two chamfering wheels 21 of the first chamfering wheel set to approach each other, so that the two chamfering wheels 21 of the first chamfering wheel set are respectively in close contact with both sides of the workpiece to be machined, and the driving assembly 3 drives the two chamfering wheels 21 of the first chamfering wheel set to rotate to drive the workpiece to be machined to move.

[0075] Through the above steps, chamfering processing of the workpiece to be machined can be performed by the first chamfering wheel set.

[0076] Optionally, continue to refer to Figure 7 , the chamfering method further includes steps S300 - S600 after step S200.

[0077] S300: Continue to convey the workpiece to be machined so that the front end of the workpiece to be machined is located between the first chamfering wheel set and the second chamfering wheel set.

[0078] Among them, when the second detection structure 62 detects that the workpiece to be machined has been conveyed between the transmitter and the receiver of the second detection structure 62, it can be determined that the front end of the workpiece to be machined is located between the first chamfering wheel set and the second chamfering wheel set.

[0079] S400: The mounting bracket driving member 4 drives the two chamfering wheels 21 of the first chamfering wheel set to move away from each other, and drives the two chamfering wheels 21 of the second chamfering wheel set to move away from each other, and the two chamfering wheels 21 of the first chamfering wheel set always contact both sides of the workpiece to be machined and can continue to drive the workpiece to be machined to move.

[0080] It can be understood that in step S200, the two chamfering wheels 21 of the first chamfering wheel set are in close contact with the workpiece to be machined, forcing the workpiece to be machined to undergo plastic deformation, thereby performing chamfering. And in step S400, although the two chamfering wheels 21 of the first chamfering wheel set move away from each other, they still contact the workpiece to be machined. At this time, the degree of plastic deformation of the workpiece to be machined is relatively low, and the chamfering wheel 21 can still drive the workpiece to be machined to continue to move. With such a setting, before the workpiece to be machined contacts the two chamfering wheels 21 of the second chamfering wheel set, the two chamfering wheels 21 of the second chamfering wheel set can be made to move away from each other first, facilitating the entry of the workpiece to be machined and avoiding the workpiece to be machined directly hitting the two chamfering wheels 21 of the second chamfering wheel set.

[0081] Optionally, the second detection structure 62 is arranged close to the second chamfering wheel set, so that in step S300, when the workpiece to be processed has been conveyed to a position closer to the second chamfering wheel set, step S400 is then executed.

[0082] S500: Continue to convey the workpiece to be processed so that the front end of the workpiece to be processed is located between the two chamfering wheels 21 of the second chamfering wheel set.

[0083] Specifically, when the second detection structure 62 detects that the workpiece to be processed has been conveyed between the transmitter and the receiver of the second detection structure 62, it can be determined that the front end of the workpiece to be processed is located between the two chamfering wheels 21 of the second chamfering wheel set after a second set time.

[0084] In addition, when the third detection structure 63 detects that the workpiece to be processed has been conveyed between the transmitter and the receiver of the third detection structure 63, it indicates that the front end of the workpiece to be processed has passed over the second chamfering wheel set at this time.

[0085] S600: Drive the two chamfering wheels 21 of the second chamfering wheel set to approach each other through the mounting bracket driving member 4, so that the two chamfering wheels 21 of the second chamfering wheel set are respectively in close contact with both sides of the workpiece to be processed, and drive the two chamfering wheels 21 of the second chamfering wheel set to rotate through the driving assembly 3 to drive the workpiece to be processed to move.

[0086] Through step S600, the two chamfering wheels 21 of the second chamfering wheel set chamfer the workpiece to be processed again to improve the chamfering effect.

For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention.
