Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blade sharpening machines, in particular to a knife profiled blade sharpening machine. BACKGROUND

[0002] Knife sharpening is to make the blade sharp through grinding and other ways, and its core value is to improve cutting performance, safety and durability.

[0003] The current way of double-sided sharpening of the knife is that the worker directly holds the knife to polish the two sides, and the quality of the knife edge is directly related to the operation method of the worker, so the quality of the traditional operation is very unstable. Moreover, the manual polishing of the magnesium oxide or aluminum oxide belt is affected by the bad effects of man, machine, material, method and environment. For example, the long working time, the decline of energy, the poor hand profile, the large deviation of the edge angle, the inconsistent width of the edge, the large change of the speed, the short contact time of the edge on the abrasive, and the rough edge will lead to the unsharpened edge. For another example, the coarse and not fine ceramic grinding wheel and abrasive belt will lead to the unsharpened edge. If the contact surface is narrow (less than or equal to 5 cm) and the contact time is short, the edge will be easily deformed. If the contact surface is wide (more than 10 cm), it will not be profiled because the human strength is limited and it is not easy to hold and stabilize the knife for profiling. The pass rate of the sharp edge is less than 60%. Therefore, the high-speed motor driven grinding wheel and abrasive belt must be used to cut the edge, and the cutting is large, the self-sharpening edge roughness is 50 μm, the cutting food resistance is large, and the edge is not sharp.

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0047] Please refer to Figures 1-10 ​The application provides a technical scheme:

[0048] The knife copying blade opening machine comprises a copying mold 101 for adjusting the shape of a copying resin grinding wheel 102 and a clamp 105 for clamping a knife blank 200, wherein the copying mold 101 is adjusted in position by a first adjusting component, the first adjusting component comprises a transverse adjuster 103 and a first longitudinal adjuster 104; the clamp 105 is adjusted in position by a second adjusting component, the second adjusting component comprises a second longitudinal adjuster 106 and an up-down adjuster 107; the transverse adjuster 103, the first longitudinal adjuster 104, the second longitudinal adjuster 106 and the up-down adjuster 107 can be adjusted in screw rod mode, specifically, the positions of the copying mold 101 and the copying resin grinding wheel 102 are adjusted by rotating a bolt, for example, the copying mold 101 is driven to move along the axial direction thereof by rotating the screw rod of the transverse adjuster 103, the copying mold 101 is driven to approach or move away from the copying resin grinding wheel 102 by rotating the screw rod of the first longitudinal adjuster 104, the transverse adjuster 103 and the first longitudinal adjuster 104 are arranged to facilitate the adjustment of the relative positions of the copying mold 101 and the copying resin grinding wheel 102 by workers; the second longitudinal adjuster 106 and the up-down adjuster 107 are used for adjusting the relative positions of the clamp 105 and the copying resin grinding wheel 102.

[0049] In the application, the peripheral surface of the copying resin grinding wheel 102 needs to be adjusted according to the blade edge line shape of the knife blank 200, as shown in the figure, Figure 2 the peripheral surface shape of the copying resin grinding wheel 102 can be adapted to the blade edge line of the knife blank 200 in the embodiment, when the knife blank 200 is at a first predetermined angle or a second predetermined angle, the second longitudinal adjuster 106 is used to drive the knife blank 200 to approach and contact the copying resin grinding wheel 102, so that the copying resin grinding wheel 102 is used to polish and open the blade of the knife blank 200, and because the peripheral surface shape of the copying resin grinding wheel 102 is adapted to the blade edge line of the knife blank 200, the opening operation of the blade of the knife blank 200 can be completed at one time by the copying resin grinding wheel 102, in other words, the length of the copying resin grinding wheel 102 can be customized, the copying resin grinding wheel 102 can completely satisfy the blade length, and the copying resin grinding wheel 102 is formed on the lathe according to the blade edge line curvature of the knife blank 200, so that the peripheral surface of the copying resin grinding wheel 102 can completely satisfy the arc line of the blade edge, and the blade edge line of the knife blank 200 can be in full contact with the peripheral surface of the copying resin grinding wheel 102, and the single-sided blade edge of the knife blank 200 is polished at one time.

[0050] Further, in order to improve the precision of the blade opening and the quality of the tool, the application also designs a special clamp 105, and the specific structure and working principle are as follows:

[0051] The clamp 105 comprises a fixed shaft 2, a rotating arm 3 rotatably connected to the fixed shaft 2, and a chuck 6 arranged at one end of the rotating arm 3 and used for clamping the blade blank 200. The axis of the fixed shaft 2 is parallel to the axis of the profiled resin grinding wheel 102, and the axis of the fixed shaft 2, the axis of the profiled resin grinding wheel 102, and the bisector 300 of the blade blank 200 clamped by the clamp 105 and in a horizontal state are all located in a horizontal plane 400, as shown in Figure 10 The rotating arm 3 is provided with at least two adjacent rotating arms 3 which are fixedly connected with an intermediate rod 33. The rotating arm 3 is rotatably connected to the fixed shaft 2 through a first bearing seat 34.

[0052] The rotating arm 3 drives the blade blank 200 to rotate between a first predetermined angle and a second predetermined angle, and the first predetermined angle and the second predetermined angle are symmetrically arranged on the upper and lower sides of the horizontal plane 400. When the blade blank 200 is located at the first predetermined angle, the first edge of the blade blank 200 can be polished by the profiled resin grinding wheel 102. When the blade blank 200 is located at the second predetermined angle, the second edge of the blade blank 200 can be polished by the profiled resin grinding wheel 102. Specifically, since the blade blank 200 needs to be double-edged, the first edge and the second edge mentioned above are the two edges of the blade blank 200.

[0053] The working principle of the above aspect is as follows: Figure 10 As shown in Figure 1 , the blade blank 200 is at the second predetermined angle and is being polished at the second edge. After the second edge is polished, the blade blank 200 is first adjusted away from the profiled resin grinding wheel 102 by using the second longitudinal adjuster 106, and then the blade blank 200 is rotated from the second predetermined angle to the first predetermined angle and is fixed, and then the blade blank 200 is adjusted to be close to the profiled resin grinding wheel 102 by using the second longitudinal adjuster 106, so that the first edge polishing operation can be performed.

[0054] In the technical scheme, the cutter blank 200 only needs to be clamped once in the whole process of double-face sharpening, and then the double-face sharpening of the cutter is completed by rotating the whole clamp to the first and second predetermined inclination angles, so that the clamping error generated in the process of clamping the cutter blank 200 from two sides is effectively avoided, the consistency of the two blade edges of the cutter blank 200 is significantly improved, and the sharpening quality of the cutter blank 200 is guaranteed. Moreover, in the rotating mode, no matter to which predetermined angle the clamp 105 drives the cutter blank 200 to rotate, the transverse direction of the cutter blank 200 does not change, for example, the first end and the second end of the cutter blank 200 at the first predetermined angle position are consistent with the first end and the second end of the cutter blank 200 at the second predetermined angle position, that is, no matter to which predetermined angle the clamp 105 drives the cutter blank 200 to rotate, the sharpening position of the cutter can be kept in contact with the peripheral surface of the profiled resin grinding wheel 102. In this way, the cutter blank 200 can be adapted to the profiled peripheral surface of the profiled resin grinding wheel 102 at the two predetermined angle positions, so as to ensure the polishing quality, and since the double-face sharpening is completed only by rotating the cutter blank 200, the polishing efficiency is improved.

[0055] The chuck 6 comprises a rotating shaft 63 rotatably connected to one end of the rotating arm 3 through a second bearing seat 61, a centering clamping part 66 arranged at one end of the rotating shaft 63, and a driving part 67 for driving the rotating shaft 63 to rotate. In the embodiment, the rotating arm 3 is cylindrical, and the rotating shaft 63 is coaxially arranged with the rotating arm 3. The centering clamping part 66 functions in the following manner: after the cutter blank 200 is clamped by the centering clamping part 66, the plane where the bisector 300 of the cutter blank 200 is located coincides with the plane where the axis of the rotating shaft 63 is located, that is, the axis of the fixing shaft 2, the axis of the profiled resin grinding wheel 102, and the bisector 300 of the cutter blank 200 clamped by the clamp 105 and in a horizontal state are all located in the horizontal plane 400. The advantage of this arrangement is that when the cutter blank 200 is rotated by the first predetermined angle or the second predetermined angle for polishing and sharpening, the opening depth and the blade angle of the first and second blade edges of the cutter blank 200 remain consistent, so that the sharpness and the qualification rate of the blade edges are improved.

[0056] The centering clamping part 66 includes a rotating piece 661 fixed at one end of the rotating shaft 63, two shaft rods 662 rotationally connected with the rotating piece 661 through a third bearing seat 663, the rotating piece 661 and the two shaft rods 662 cooperatively forming a U-shaped structure, and the distance between the axes of the two shaft rods 662 and the axis of the rotating shaft 63 being equal; when the rotating shaft 63 rotates, the two shaft rods 662 can be driven to rotate synchronously by the rotating piece 661, thereby ensuring that the two shaft rods 662 can make the plane where the bisector 300 of the blade blank 200 is located coincide with the plane where the axis of the rotating shaft 63 is located after clamping the blade blank 200; and the space occupied by the centering clamping part 66 is small after clamping the blade blank 200, and the centering clamping part 66 will not adversely affect the blade opening operation of the blade blank 200, for example, the centering clamping part 66 will not be in contact with the profile resin grinding wheel 102 during the blade opening process of the blade blank 200 by the profile resin grinding wheel 102, thereby avoiding the wear of the profile resin grinding wheel 102.

[0057] To improve the clamping tightness, in the embodiment, the shaft rod 662 is fixedly connected with a clamping plate 664, which can increase the contact area between the shaft rod 662 and the blade blank 200, improve the clamping stability, and further, as shown in Figure 9 after clamping the blade blank 200, the two clamping plates 664 have an overlapping portion 666 in the direction perpendicular to the side surface of the blade blank 200, and the overlapping portion 666 is the contact portion of the clamping plate 664 and the blade blank 200; the overlapping portion 666 can prevent the blade blank 200 from being deformed after being clamped by the two shaft rods 662, thereby ensuring the blade opening quality of the blade blank 200. The clamping surface of the clamping plate 664 is provided with a gasket 665, which is used to increase the friction between the clamping plate 664 and the blade blank 200, and the hardness of the gasket 665 should be less than that of the blade blank 200, so as to avoid scratching the blade blank 200.

[0058] The chuck 6 further includes a gear 62, a rack 65 engaged with the gear 62, and a synchronization rod 64 fixedly connected with the rack 65; the gear 62 is coaxially fixedly sleeved on the outside of the rotating shaft 63; the synchronization rod 64 is driven to move linearly by a driving member 67. In the embodiment, the movement of the synchronization rod 64 and the rack 65 can drive the rotating shaft 63 to rotate by cooperating with the gear 62, and the overall structure is simple and occupies a small space.

[0059] The driving member 67 includes a driving cylinder 671, which can be an electric cylinder in the embodiment, and the free end of the driving cylinder 671 is fixedly connected with the synchronization rod 64 through a synchronization block 672. An intermediate rod 33 is fixedly provided with a sliding rail 674, and a sliding block 673 is slidingly arranged on the sliding rail 674 and fixedly connected with the synchronization rod 64.

[0060] The chuck 6 further comprises the fixed frame 1, the upper limiting frame 4 and the lower limiting frame 5; the fixed shaft 2, the upper limiting frame 4 and the lower limiting frame 5 are fixedly arranged on the fixed frame 1, and the upper limiting frame 4 and the lower limiting frame 5 are symmetrically distributed on the two sides of the fixed shaft 2; when the rotating arm 3 is in contact with the upper limiting frame 4, the blade blank 200 is at a first predetermined angle; when the rotating arm 3 is in contact with the lower limiting frame 5, the blade blank 200 is at a second predetermined angle; the positions of the rotating arm 3 are limited by the upper limiting frame 4 and the lower limiting frame 5, so that the rotating arm 3 is conveniently rotated to the first predetermined angle or the second predetermined angle.

[0061] Further, the upper limiting frame 4 and the lower limiting frame 5 each comprise a fixedly connected connecting block 41 and an inclined block 42; the connecting block 41 is fixedly mounted on the fixed frame 1; the inclined block 42 is provided with a positioning groove 43 on the side facing the rotating arm 3, the positioning groove 43 is arranged in matching with the rotating arm 3, and the inclined block 42 is provided with a through groove 44 on the side away from the rotating arm 3; the rotating arm 3 is fixedly provided with a stud 31 on the upper and lower sides, and the stud 31 is threadedly connected with a nut 32. Specifically, when the rotating arm 3 is rotated to the inside of the positioning groove 43, the stud 31 penetrates through the through groove 44, at this time, the nut 32 is tightened, so that the rotating arm 3 is locked in the upper limiting frame 4 or the lower limiting frame 5, and the stability of the blade blank 200 in the blade sharpening process is ensured.
