Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of grinding machine, more particularly, relates to a shearing blade edge bevel processing auxiliary device, a grinding machine system and a processing method thereof. BACKGROUND

[0002] Most of the metallurgical shearing blades have bevels at the edge positions, and the edge bevels are acute angles, and the angles are mostly 0-45°. The existence of the acute angle bevels has the advantages of reducing shearing resistance, improving plate strip cutting surface quality, and improving shearing efficiency. The shearing blade edge bevel processing quality is related to the shearing quality and service life of the shearing blade, and therefore the processing of the shearing blade edge bevel is particularly important. In order to meet the size and surface finish requirements of the edge bevel, a grinding machine is mostly used in the shearing blade machining process to perform fine grinding processing on the edge bevel.

[0003] Most of the existing grinding machines process bevels by using the sand wheel repairing method, that is, the sand wheel is repaired to a fixed angle, so that the required bevel angle is formed in the grinding process. However, at present, only numerical control forming grinding machines can repair the sand wheel by programming the inclined path, and the surface grinder cannot repair the sand wheel. The numerical control forming grinding machine is mostly used for arc surface fine grinding, and is not suitable for some small-scale places due to its high cost. In addition, the sand wheel repairing method is generally only suitable for fine grinding of bevels of 20° and below. When the bevel angle is greater than 20°, the sand wheel angle is too large, which shortens the service life of the sand wheel and may cause the sand wheel to collapse. The surface of the repaired sand wheel is rough, which leads to a decrease in grinding quality. Therefore, it is of important production practical significance to design a more economical shearing blade edge bevel fine grinding device that can ensure the grinding quality.

[0004] After searching, the patent CN202716123U discloses a special polishing machine for shearing blade surface. The application includes a grinding wheel and a workbench below the grinding wheel. A clamp block for fixing the shearing blade is arranged on the workbench, the lower end surface of the clamp block is parallel to the workbench, the upper end surface of the clamp block towards the grinding surface of the grinding wheel is an inclined surface, the included angle between the inclined surface and the grinding surface of the grinding wheel is equal to the included angle of the shearing blade edge section, a convex column matched with the center hinge hole of the shearing blade is arranged on the inclined surface, and a stop block matched with the back blade end of the shearing blade is also arranged on the inclined surface. By using the above structure, the shearing blade can be placed on the inclined surface of the clamp block, the center hinge hole of the shearing blade is sleeved with the convex column on the inclined surface of the clamp block, the back blade end of the shearing blade is in contact with the stop block on the inclined surface of the clamp block, and finally the shearing blade is in contact with the grinding wheel to polish the blade surface.

[0005] For example, in the patent CN207900932U, a flying shear shear knife repair grinding clamp is disclosed. The application includes a shear body, the included angle between the inclined edge of the shear body and the horizontal plane is β, and the clamp further includes a bottom plate, an inclined support plate, a bottom support plate and two shear body fixing plates; the bottom plate is a rectangular parallelepiped and is placed horizontally; the inclined support plate is welded with the bottom plate at an angle α, a gap is reserved at the connection, the connection is connected by a weld, and the bottom support plate is vertically welded with the inclined surface of the inclined support plate above the bottom plate; the shear body fixing plates are respectively arranged at both ends of the bottom plate and are connected and fixed with the bottom plate and the inclined support plate; bolt through holes are arranged on the shear body fixing plates, and fixing bolts are installed. The application can be used with a surface grinding machine to repair and grind the inclined edge of the shear, has high machining precision, greatly improves the service life of the shear, and improves the working efficiency and product quality of the flying shear.

[0006] The above-mentioned application adopts a positioning clamp form, so that the shear blade to be machined is adjusted to be parallel to the grinding machine workbench and the grinding wheel to realize the grinding machine machining of the inclined surface. This mode can be used with a surface grinding machine, and the positioning clamp structure is simple, and is more economical and applicable than the grinding wheel repair method. However, there is still some optimization space, for example, the clamp in the above-mentioned application can only be applied to machining of an inclined surface of one angle, and different clamps are required to be re-made for machining of inclined surfaces of different angles, so that the cost control is not facilitated. In addition, frequent replacement and use of multiple clamps are also not conducive to improving the working efficiency. SUMMARY

[0041] In order to further understand the content of the present application, the present application will be described in detail in combination with the drawings.

[0042] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for description purposes and cannot be understood as indicating or implying relative importance.

[0043] The present application will be further described below in combination with specific embodiments.

[0044] As shown in Figure 1 , Figure 2 The shear blade edge bevel processing auxiliary device of the embodiment includes a mounting seat 1, a rotating seat 2, and a driving assembly 3. The rotating seat 2 is arranged on the mounting seat 1 and is used to support and limit the to-be-processed shear blade 4. The driving assembly 3 is used to drive the rotating seat 2 to rotate and in turn drive the to-be-processed shear blade 4 to rotate, so as to adjust the edge bevel of the to-be-processed shear blade 4 to a horizontal state, facilitating the processing operation of the bevel later.

[0045] Specifically, as shown in Figure 4 , Figure 5 The mounting seat 1 is a rectangular block as a whole, and an arc-shaped mounting groove 11 is arranged on the mounting seat 1, and the rotating seat 2 is arranged in the mounting groove 11. In order to facilitate processing, the mounting groove 11 is a through groove along the width direction (i.e., the Y direction in Figure 4 .

[0046] The rotating seat 2 as a whole can be regarded as a part of a cylinder, and the outer peripheral wall of the rotating seat 2 is consistent with the inner arc surface of the mounting groove 11, so as to facilitate the rotating seat 2 to rotate along the inner arc surface of the mounting groove 11, and further drive the to-be-processed shear blade 4 to rotate, so as to adjust the blade edge bevel of the to-be-processed shear blade 4 to a horizontal state. The two end faces of the cylinder are the two ends of the rotating seat 2, and the circumferential surface of the cylinder is the outer peripheral wall of the rotating seat 2.

[0047] The cylinder is cut along the axial direction to form a notch penetrating at least one end, and the notch forms a placing groove 21 for placing the to-be-processed shear blade 4. Actually, the placing groove 21 is composed of two planes, and the cross section is L-shaped, and a through groove is further arranged at the intersection of the two planes, so as to facilitate the stable placement of the to-be-processed shear blade 4, and at the same time, the to-be-processed shear blade 4 is protected at the corner. The two mutually perpendicular planes of the to-be-processed shear blade 4 are respectively matched with the two planes of the placing groove 21. Similarly, for the convenience of processing, the placing groove 21 is a through groove penetrating the two ends of the cylinder.

[0048] In order to ensure the stability of the rotating seat 2 during rotation, in the embodiment, an arc-shaped protrusion 22 is arranged on the outer peripheral wall of the rotating seat 2, and an arc-shaped groove 12 for clamping the arc-shaped protrusion 22 is arranged in the inner wall of the mounting groove 11. Of course, the arc-shaped groove 12 can also be arranged on the outer peripheral wall of the rotating seat 2, and the arc-shaped protrusion 22 is arranged on the inner wall of the mounting groove 11. Through the cooperation of the arc-shaped protrusion 22 and the arc-shaped groove 12, on the one hand, the rotation of the rotating seat 2 can be well guided to prevent axial deviation; on the other hand, the contact area between the mounting seat 1 and the rotating seat 2 can be reduced to reduce the frictional resistance.

[0049] Preferably, the arc-shaped protrusions 22 are two and are respectively located near the two ends of the rotating seat 2. At the same time, the arc-shaped protrusions 22 can be made of some materials with low friction coefficient.

[0050] Reference Figure 3 As shown, the driving assembly 3 includes a push rod 31, a rotating arm 32 and a driving source 33. The rotating arm 32 is provided with two, and is respectively located at the two ends of the rotating seat 2; the push rod 31 is also provided with two, and is respectively located at the two sides of the mounting seat 1 in the length direction (i.e. the X direction in the figure). Figure 4 One end of the push rod 31 is connected with the rotating seat 2, and the other end is connected with the driving source 33 at the end of the mounting seat 1, for transmitting power to the rotating seat 2 through the rotating arm 32.

[0051] In addition, a through rotation groove 13 is formed in the mounting base 1 below the placement groove 21. The rotation groove 13 is an arc-shaped groove extending along the axis of the mounting groove 11 and concentric with the placement groove 21. Meanwhile, a rotation column 34 is arranged in the placement groove 21, and the end of the rotation column 34 extends out of the rotation groove 13 and is connected with the push rod 31 and the rotation arm 32. In this embodiment, the rotation groove 13 controls the moving direction of the rotation column 34, which is also conducive to ensuring the stability of the rotation base 2.

[0052] Further, the mounting base 1 is also provided with a scale mark 14 matched with the arc-shaped groove 12. Meanwhile, the rotation column 34 is provided with a pointer 37 pointing to the scale mark 14. The scale mark 14 and the pointer 37 can more intuitively determine the rotation angle of the rotation base 2.

[0053] In this embodiment, the driving source 33 is a regulating bolt. Meanwhile, a threaded hole 15 matched with the threaded section of the regulating bolt is formed in the mounting base 1. The threaded hole 15 is arranged at the end of the mounting base 1 and extends along the length direction of the mounting base 1. The threaded cooperation between the regulating bolt and the threaded hole 15 provides the push rod 31 with a pushing force.

[0054] In order to prevent the regulating bolt from interfering with other connecting components during rotation, a bushing 35 is arranged on the non-threaded section of the regulating bolt. The two opposite sides of the bushing 35 are connected with the end of the push rod 31 through a connecting rod 36, so as to ensure the smoothness of the adjusting operation.

[0055] The blade edge bevel processing auxiliary device of this embodiment drives the rotation base 2 to rotate along the inner arc surface of the mounting groove 11 through the driving assembly 3, and then drives the to-be-processed blade 4 to rotate, so as to adjust the blade edge bevel of the to-be-processed blade 4 to a horizontal state. The angle of the grinding wheel does not need to be adjusted, so that the grinding machine can be used in cooperation with the surface grinder. Compared with the numerical control forming grinder, the cost of equipment investment can be greatly reduced. In addition, the rotation base 2 can realize continuous multi-angle rotation in the mounting groove 11, so as to be applicable to the processing requirements of blades with different angle bevels without the need to process multiple angle clamps. This is not only conducive to further controlling the cost, but also avoids the drawbacks of switching between different toolings, which can greatly improve the work efficiency and the scope of application.

[0056] Reference Figure 6 As shown in the drawings, the embodiment also provides a grinding machine system, which comprises a surface grinder and the blade edge bevel processing auxiliary device. The surface grinder comprises a magnetic workbench 51 and a grinding wheel 52. The magnetic workbench 51 is provided with at least two blade edge bevel processing auxiliary devices distributed along the length direction thereof. The grinding wheel 52 is installed on a guide rail 54 through a grinding wheel frame 53.

[0057] The working flow of the grinding machine system of the embodiment is as follows:

[0058] The shear blade 4 to be processed is placed in the placing groove 21 of the rotating seat 2, so that the two mutually perpendicular surfaces of the shear blade 4 are respectively attached to the two planes of the placing groove 21, and the bevel edge of the shear blade 4 is ensured to be entirely upward;

[0059] The adjusting bolt is screwed to drive the upper bushing 35 to move; in the moving process of the bushing 35, the rotating column 34 is driven to move in the rotating groove 13 through the connecting rod 36 and the push rod 31; the rotating column 34 drives the rotating seat 2 to rotate through the rotating arm 32; at the same time, the specific scale of the pointer 37 points to the specific scale of the scale mark 14, so that the specific rotating angle of the rotating seat 2 can be determined, until the bevel edge of the shear blade 4 to be processed is completely horizontal, the adjusting operation is completed;

[0060] Finally, the position of the grinding wheel 52 is adjusted and started, so that the bevel edge of the shear blade 4 to be processed can be processed.

[0061] The above description of the present application and its embodiments is illustrative and not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the present application, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above description, without departing from the spirit of the present application, similar structural modes and embodiments can be designed without creativity, which should also belong to the protection scope of the present application.
