Description

Technical Field

[0001] The invention relates to the field of corrugated shearing technology, in particular to an edged alloy corrugated shearing tool, a shearing mechanism and a shearing method. Background Art

[0002] The wave shearing machine mold is a key component in the wave shearing production line, which is formed by pressing the upper mold frame and the lower mold frame. Since the upper and lower cutters of the existing wave shears are split assembly structures and made of cemented carbide. The split assembly structure increases the cumulative error and reduces the shearing accuracy. In the shearing process, burrs or burrs are easily generated due to the split setting on the edge, resulting in the need for rework of the workpiece; and the use of cemented carbide materials is prone to higher production costs.

[0003] Reference document CN2009201925146 Wave shearing mold in wave shearing production line discloses a wave shearing mold in a wave shearing production line, including an upper die base and a lower die base, the upper die base and the lower die base are connected by four guide columns respectively arranged at the four corners, the upper die base and the lower die base are respectively provided with fixed plates, the two fixed plates are respectively provided with stepped table tops, and the table tops are respectively provided with wave shearing upper die and lower die used in conjunction with each other; and a discharge plate is provided on the lower die base, and a plurality of guide shafts are provided on the discharge plate, one end of the guide shaft is fixed on the discharge plate, and the other end is movably arranged in the guide shaft hole of the die base, and a reset device is provided between the discharge plate and the lower die base. The mold and the die base of this application are manufactured and processed separately, and the processing accuracy is more reasonable. However, the top heights of the fixed plates and the discharge plates on both sides of the lower die are lower than its height, which leads to easy blockage in the feeding direction. Secondly, the material used on the mold does not involve lifting, so it has poor wear resistance.

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] Example 1

[0059] See also Figure 1-4 The present invention provides a technical solution, a rimmed alloy corrugated shearing tool, comprising a substrate 1, on which a horizontal positioning hole 11 and a vertical positioning hole 12 are opened; symmetrical connecting ports 13 are arranged at the corners of the substrate 1, and a rimmed alloy 2 is installed in the connecting port 13; at least two groups of rimmed alloys 2 are arranged and are horizontally parallel; the axis of the horizontal positioning hole 11 is arranged horizontally and perpendicular to the vertical positioning hole 12.

[0060] In a further technical solution, the length of the edging alloy 2 matches the length of the substrate 1, the width of the edging alloy 2 is 1 / 6 of the substrate, and the height of the edging alloy 2 is 1 / 5 of the substrate 1; the edging alloy 2 is rectangular. The edging process can be welded, fused, bonded or manually inlaid to firmly fix the edging alloy on the substrate.

[0061] Differentiating the sectional wave shears in the prior art, it is necessary to solve the problem that the existing wave shears are made of hard alloy as a whole, which leads to excessive cost. The present invention adopts an integral long strip wave shear, so that the length of the wave shear is consistent with the length of the upper mold frame or the lower mold frame, which can also solve the burr problem caused by the sectional wave shears. And the edge alloy is used to achieve wear-resistant treatment, which reduces the cost of a single set of wave shears. The detachable integral wave shear can also be disassembled and polished twice to make its working surface sharp and easy to cut.

[0062] Example 2

[0063] like Figure 5-6 , which is another embodiment of the present invention, based on Example 1, the substrate 1 and the edging alloy 2 are provided with a notch 3 opposite to each other, and the pair forms a cavity, and the cavity is suitable for welding buried seams;

[0064] The edging alloy 2 includes a working area 21, a transition area 22 and a base load area 23, and a dividing line is set between the working area 21 and the transition area 22, and the dividing line is curved and protrudes outward;

[0065] The working area material components include: C: 0.05-1.20 parts, Ni: 10.2-15.2 parts, Co: 3.8-5.7 parts, Mo: 0.4-1.2 parts, Cr: 9.0-12.5 parts, Al: 1-3 parts, B: 2.0-3.2 parts, Si: 4.2-5.6 parts, P: 0.01-0.04, and the balance is Fe and residue; among which, 0.069≤(B+Co) / (Fe+Ni+Cr)≤0.106, 0.079≤(Si+Al+C) / Fe≤0.170;

[0066] The working area material is nickel-chromium alloy, and Co is added to ensure the high-temperature creep strength of the heat-resistant alloy; an appropriate amount of Si and Al are added to help increase the fluidity of the heat-resistant alloy and serve as a deoxidizer. Since Ni easily forms nickel oxide with oxygen at high temperatures, it is easy to produce pores during crystallization. In order to avoid a large number of residual pores, which leads to shedding of the connection parts, especially the relative boundary position, Si and Al are added; secondly, Si and Ti produce an oxide layer during the alloy preparation process to form an oxide film with high wear resistance. The B element can significantly refine the grains of the aluminum alloy, making the grain boundaries smaller and cleaner. Ti can combine with impurity elements at the grain boundaries to form stable compounds, thereby inhibiting the growth of grains and stabilizing the grain boundary structure. This embodiment uses elements that enhance the formation of oxide film materials on nickel-chromium alloys, so that the working area material is the actual cutting and extrusion workpiece material, which requires high wear resistance to achieve a long service life.

[0067] The transition zone components include: Ni: 50-55 parts, Cr: 15-19 parts, Nb: 4.20-5.35 parts, Mo: 2.8-3.3 parts, Ti: 0.75-1.45 parts, Al: 0.3-0.8 parts, C: 0.02-0.08 parts, B: 0-0.06 parts, and the balance is Fe and residue; wherein, 0.016≤(Al+Ti) / (Ni+Cr)≤0.034, 0.066≤(Nb+Ti) / (Ni+Cr)≤0.104;

[0068] The transition zone material is nickel-chromium alloy. The high content of Ni improves the stability of the matrix face-centered cubic γ phase and improves the tendency of the heat-resistant alloy to precipitate various harmful phases, so that it can improve the strength of the steel while maintaining good plasticity and toughness. The heat-resistant alloy is added with the solid solution element Cr, so that the heat-resistant alloy has a multi-solution strengthening effect, which increases the use temperature of the slider; the outstanding load-bearing temperature plays a role in high-temperature connection between the load-bearing working area and the base load area in the transition zone.

[0069] The components of the base carrier zone include: C: 0.4-1.2 parts, Mn: 32.7-55.2 parts, Co: 4.2-6.5 parts, Nb: 4.80-6.35 parts, Ti: 1.2-1.8 parts, Al: 2.0-3.6 parts, Si: 3.5-5.6 parts, P: 0.01-0.04, and the balance is Fe and residue; 0.040≤(Al+Ti) / (Mn+Fe)≤0.059, 0.074≤(Nb+Ti) / (Mn+Fe)≤0.090.

[0070] The Nb element can refine the crystal particle size, enhance its strength and wear resistance, control the P content, and avoid affecting the high temperature durability of the heat-resistant alloy; the Nb element can form a stable γ' strengthening phase to achieve strength optimization. The Nb element forms a nano-scale carbide second phase inside, which significantly reduces the overheating sensitivity of the coating, refines the grains, forms a variety of metal compound phases, promotes the nucleation and growth of the grains, thereby obtaining fine grains, and refines the grains by hindering the growth of the grains and inhibiting the movement of the grain boundaries, so that the metal compounds have high strength and hardness. As a base load area, it can achieve the effect of effectively supporting the transition zone, thereby strengthening the strength and hardness of the base load area.
