Description
Technical field
The invention belongs to mechanical equipment technical field, relate in particular to a kind of wire rod cold-heading equipmentMaterial cutting mechanism.
Background technology
Wire rod can be carried out before the upsetting pressure process of cold headers die-cut, and die-cut process tenPoint be particular about, die-cut precision, die-cut speed, die-cut dynamics etc., many factors are allCan the die-cut quality of impact. For example, carrying out when die-cut, the feed mechanism of equipment can be by lineMaterial is at the uniform velocity sent into die-cut position, die-cut cutter head at the uniform velocity carry out reciprocal blankerDo, if wire rod speed change is sent into or die-cut all can the causing of carrying out of die-cut cutter head speed change rushesMaterial after cutting is different in size, and material different in size will be served as waste material, thereby greatlyIncrease production cost. Then, even if wire rod can at the uniform velocity be sent into die-cut position, die-cutWhen cutter head carries out cutting action downwards, although die-cut action fast accurate, wire rod is still even, there is most probably the phenomenon that die-cut dipped ring is whole, although be extremely trickle in the movement of speedSmooth, but cannot ensure that the irregularity degree of otch of each material is identical, therefore may processAfter product can aspect quality and shape, cannot better unify, if for Product PrecisionHave relatively high expectations, such has the product of out-of-flatness tangent plane will be used as waste material.
The problem existing in order to solve prior art, people have carried out long-term exploration, proposeSolution miscellaneous. For example, Chinese patent literature discloses a kind of die-cutMachine, [application number: 200810238535.7], comprises lathe, on lathe, install clamping device,Tool rest and frame, install vertical die-cut hydraulic cylinder in frame, vertical die-cut hydraulic cylinder lower end peaceFill the first punching cutter, the first tilting die-cut hydraulic cylinder is installed respectively in vertical die-cut hydraulic cylinder both sidesWith the second tilting die-cut hydraulic cylinder, the first tilting die-cut hydraulic cylinder and the second tilting die-cut hydraulic pressureThe second punching cutter and the 3rd punching cutter are installed respectively in cylinder lower end, and tool rest is positioned under the first punching cutterSide, offers cutter groove on tool rest.
Above-mentioned scheme has been improved the subproblem of prior art to a certain extent, still,Also at least there is following defect in this scheme: complex structure, cannot compress preferably material,Cannot solve preferably the irregular problem of tangent plane.
