Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of grain machine rotating shaft metal die.
Background technology
The rotating shaft of grain machine is one of important spare part of Cereals Processing Machines, and it originally adopted the direct processing aluminum materials of mechanical processing tools to be formed or adopted mould to make.Because the efficiency of machining is lower, and percent defective is higher, is easy to the waste causing aluminium, adds processing cost and human cost, therefore, usually adopts Mold Making now.
Grain machine rotating shaft through Making mold usually can with running channel, cinder ladle, the foreign material that vacuum runner etc. are unnecessary, and in order to improving product quality, must knock off and remove the above foreign material with hammer, this processing mode easily strikes bad product, causes product to collapse scarce, distortion.And remove unclean, often jagged and runner remains.
Therefore, be necessary to provide a kind of new processing mode to solve the problems referred to above.
Utility model content
The purpose of this utility model is to provide a kind of grain machine rotating shaft metal die effectively can removing the qualification rate of the foreign material such as product burr and cinder ladle and guarantee product.
To achieve these goals, the technical scheme that adopts of the utility model is as follows:
A kind of grain machine rotating shaft metal die, comprise dynamic model and cover half, described cover half comprises some templates be parallel to each other, described cover half is provided with some guide pillars, described dynamic model is provided with and matches and the guide pin bushing that can slide along described guide pillar with described guide pillar, described guide pillar is equal with described guide pin bushing quantity, described dynamic model is also provided with pusher, described pusher comprises hydraulic jack, pull bar and spring, described spring housing is on described pull bar, the first end of described pull bar is connected with described hydraulic jack, second end of described pull bar is fixed with the baffle plate for blocking described spring, described dynamic model is also provided with cutting knife, the blade of described cutting knife comprises the one side directly contacted with product, be designated as the first contact surface, described first contact surface comprises the first plane and the second plane, angle between described first plane and the template of described cover half is 10-35 °, described second plane orthogonal is in the template of described cover half.
Preferably, described first plane is shiny surface, and described second plane is frosting.
Preferably, the area of the circle corresponding to turn external diameter of described spring is less than the cross-sectional area of described baffle plate.
Preferably, the turn internal diameter of described spring is greater than the cross-sectional diameter of described pull bar.
Preferably, described baffle plate is circular or square.
Preferably, the length of described pull bar is less than the length under described spring free state.
Compared with prior art, the beneficial effect of the utility model grain machine rotating shaft metal die is: described cutting knife can excise the foreign material such as the burr of product edge, second plane of described cutting knife can be polished the product edge after cut burr, decrease the polishing work in rear road, the burr removal efficiency of product and quality stability improve greatly; The elastic force of described spring can make described baffle plate ejecting product.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model one preferred embodiment;
Fig. 2 is perspective view of the present utility model;
Fig. 3 is the structural representation of pusher described in the utility model;
Fig. 4 is the structural representation of cutting knife described in the utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described further.
Refer to shown in Fig. 1 to Fig. 4, the utility model grain machine rotating shaft metal die comprises dynamic model 1 and cover half 2, described cover half 2 comprises some templates be parallel to each other, described cover half 2 is provided with some guide pillars 4, described dynamic model 1 is provided with and matches and the guide pin bushing (not shown) can slided along described guide pillar 4 with described guide pillar 4, described guide pillar 4 is equal with described guide pin bushing quantity, described dynamic model 1 is also provided with pusher, described pusher comprises hydraulic jack 5, pull bar 6 and spring 7, described spring 7 is enclosed within described pull bar 6, the length of described pull bar 6 is less than the length under described spring 7 free state, the first end of described pull bar 6 is connected with described hydraulic jack 5, second end of described pull bar 6 is fixed with the baffle plate 8 for blocking described spring 7.
Wherein said baffle plate 8 is circular or square, and the area of the circle corresponding to turn external diameter of described spring 7 is less than the cross-sectional area of described baffle plate 8, and the turn internal diameter of described spring 7 is greater than the cross-sectional diameter of described pull bar 6.
In the present embodiment, described dynamic model 1 is also provided with cutting knife 9, the blade of described cutting knife 9 comprises the one side directly contacted with product 3, be designated as the first contact surface 901, described first contact surface 901 comprises the first plane 901a and the second plane 901b, described first plane 901a is shiny surface, angle between described first plane 901a and the template of described cover half 2 is 10-35 °, be convenient to cutting products 3, described second plane 901b is frosting, described second plane 901b is perpendicular to the template of described cover half 2, second plane 901b of described cutting knife 9 can polish product 3 edge after cut burr, decrease the polishing work in rear road, the burr removal efficiency of product 3 and quality stability improve greatly.
Operation principle of the present utility model is: product 3 placed by described cover half 2, described dynamic model 1 is descending along described guide pillar 4, part beyond excision product 3, the elastic force of described spring 7 makes described baffle plate 8 ejecting product 3, the up return of dynamic model 1, described hydraulic jack 5 drives described pull bar 6 to regain, and takes out product 3, and circulation terminates.
