Technical field
This utility model relates to mould applications, and relates more specifically to a kind of cutter head of trimming mold for aluminum alloy die casting.
Background technology
Fig. 1 shows the edger of prior art.The cutter head of trimming mold of prior art is the traditional vertical cut formula edge of a knife using stamping die, and cutting edge is sharp, and pressure is concentrated, and all flush shear forces are all gathered on a line of cutting edge.Fig. 2 shows the schematic diagram of the cutter head of trimming mold of prior art.It can be seen that the cutter head of trimming mold of prior art is chamfer trapezoidal shape, it is perpendicular to the straight plane of horizontal plane, a tapered plane including one and connects the horizontal plane of straight plane and tapered plane.For aluminum alloy die casting, there is following defect in the tradition vertical cut formula edge of a knife: owing to aluminum alloy die casting is in press casting procedure, at the cast gate of cinder ladle or running channel, a part of filtering residue can be remained (mainly due to aluminum liquid exists aluminum slag, through cast gate, have the highest probability to be stopped by narrow cast gate), aluminum slag ground is hard, when removing running channel and cinder ladle, not only cannot excise, and owing to cutting edge departs from product for the extruding of aluminum slag, the aluminum slag inserting interiors of products, cause large area to collapse material and cause product rejection.Fig. 3 shows the schematic diagram during cutter head of trimming mold removing running channel of prior art, as shown in Figure 3, for removing the running channel 3 of product 2, there is aluminum slag 4 in product 2, when cutter head of trimming mold 1 acts on running channel 3 in cutter head of trimming mold 1, to 3 one flush shear forces along the direction indicated by arrow A of running channel, failing to cut off by running channel 3, the power of reversely sticking up along the direction indicated by arrow B can be produced in product 2 with cast gate 5 as fulcrum, thus destroy product, cause product rejection.
The purpose of this utility model, it is simply that for the sled material problem caused by aluminum slag when solving aluminum alloy die casting trimming, to reduce scrappage.
Utility model content
This utility model is a kind of cutter head of trimming mold for aluminum alloy die casting provided for above-mentioned the deficiencies in the prior art.
For achieving the above object, the technical scheme that this utility model is taked is as follows:
A kind of cutter head of trimming mold for aluminum alloy die casting, it includes that the convex R shape edge of a knife, the described convex R shape edge of a knife include that a plane and a convex surface, described plane and described convex surface are crossed to form cutting edge.
Further, the tangent plane of described plane and described convex surface forms the angle being less than 180 degree more than zero degree.
Further, the tangent plane of described plane and described convex surface forms the angle being less than 90 degree more than zero degree.
A kind of trimming equipment, it includes frame, rotary apparatus, edger, wherein
Described rotary apparatus is arranged in described frame, treats the aluminum alloy die casting of trimming for placing and drives described aluminum alloy die casting to rotate;Described edger is arranged in described frame, is used for cutting described aluminum alloy die casting, and described edger is installed above-mentioned cutter head of trimming mold, and described edger connects hydraulic means, for driving described edger to move up and down by hydraulic pressure.
Owing to using above technical scheme, the beneficial effects of the utility model include: the cutter head of trimming mold for aluminum alloy die casting that this utility model provides has the convex R shape edge of a knife, can give one extruding force of cast gate, effectively alleviate the die-cut arm of force during use.When using cutter head of trimming mold trimming of the present utility model, cutting mode is for tapping, it is to avoid cutting edge collapses material, simultaneously because the synchronization action of " tapping+extruding ", changing stress point, the pressure that will hit against focuses on fulcrum, and when reducing removing running channel, aluminum slag is for the destruction of product.

Detailed description of the invention
For reaching the disclosedest purpose, below with reference to drawings and Examples, this utility model is described in further details.Should be appreciated that specific embodiments described below is only used for explaining this utility model, be not intended to limit protection domain of the present utility model.
This utility model provides a kind of cutter head of trimming mold for aluminum alloy die casting.As shown in Figure 4, this cutter head of trimming mold includes the convex R shape edge of a knife 6.The convex R shape edge of a knife 6 includes plane 7 and outside convex surface 8.Plane 7 and convex surface 8 are crossed to form cutting edge 9.
In technique scheme, the tangent plane of plane 7 and convex surface 8 forms the angle being less than 180 degree more than zero degree.Preferably, the tangent plane of plane 7 and convex surface 8 forms the angle being less than 90 degree more than zero degree.
Fig. 5 shows and uses the schematic diagram when the cutter head of trimming mold removing running channel of aluminum alloy die casting of the present utility model.When cutter head of trimming mold taps running channel downwards along the direction indicated by arrow C, cutting edge acts at cast gate, convex surface is pressed against cast gate, pressure is concentrated at cast gate, due to the particular design of the edge of a knife, to one, cast gate along while the percussion power in the direction indicated by arrow E, can give cast gate (fulcrum) extruding force along the direction indicated by arrow D, eliminate arm lever, effectively alleviate the die-cut arm of force.This utility model, by " die-cut " action of prior art is changed into the simultaneously operating of " tapping+extruding ", changes impetus, effectively alleviates the die-cut arm of force, reduces the destruction to product when removing running channel.
This utility model additionally provides a kind of trimming equipment.As shown in Figure 6, this trimming equipment includes frame 10, rotary apparatus 11, edger 12.Rotary apparatus 11 is arranged in frame 10, treats the aluminum alloy die casting of trimming for placing and drives described aluminum alloy die casting to rotate.Edger 12 is arranged in frame 10, for running channel and the cinder ladle of the die casting that cuts aluminum alloy.The cutter head of trimming mold that above-mentioned this utility model provides is installed on edger 12.Edger 12 connects hydraulic means, for driving edger to move up and down trimming action by hydraulic pressure.
The method using above-mentioned trimming equipment trimming comprises the following steps: be installed on edger by cutter head of trimming mold;Edger is installed on trimming equipment;The aluminum alloy die casting treating trimming is fixed on the rotary apparatus of trimming equipment;Drive cutter head of trimming mold to move downward by hydraulic pressure, make the cutting edge of the convex R shape edge of a knife be depressed at cast gate and the convex surface of the described convex R shape edge of a knife is pressed against cast gate, treat to complete at trimming trimming by percussion.
The cutter head of trimming mold for aluminum alloy die casting that this utility model provides has the convex R shape edge of a knife, can give one extruding force of cast gate, effectively alleviate the die-cut arm of force during use.When using cutter head of trimming mold trimming of the present utility model, cutting mode is for tapping, it is to avoid cutting edge collapses material, simultaneously because the synchronization action of " tapping+extruding ", changing stress point, the pressure that will hit against focuses on fulcrum, and when reducing removing running channel, aluminum slag is for the destruction of product.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
