The specific embodiment
The embodiment of column mould of the present utility model, as depicted in figs. 1 and 2, this mould comprises plate edge folding machine structure and location structure, and the plate edge folding machine structure comprises moulding dynamic model 1 and carcass pedestal 2, and location structure is on the moulding dynamic model.Convex with the moulding carcass 3 that along the vertical direction extend adaptive with the inner chamber of column on the carcass pedestal 2, moulding carcass 3 be shaped as cube, the upper side of moulding carcass 3 be origin reference location face, left and right side be moulding locating surface, edge, the left and right sides the right angle transition face for the bending locating surface, the inside of moulding carcass 3 is equiped with the calandria 4 that is in moulding locating surface position.Be equiped with a pair of L shaped paw 5 that is in moulding carcass 3 left and right sides on moulding dynamic model 1 body, one end brachium of paw 5 is shorter, other end brachium is longer, the galianconism end is the origin reference location end that is in origin reference location face top, long arm end is the moulding positioning end that is in outside the left and right sides of moulding carcass 3, and paw 5 also has between the origin reference location of being in end and the moulding positioning end, the bending location division at the corner location place of paw 5, offer on the bending location division for paw 5 is rotated the installing hole that is assemblied on the moulding dynamic model 1 around the axis vertical with perpendicular, installing hole on two paws 5 is in respectively outside the left and right sides of moulding carcass 3, and the radius of gyration sum of two origin reference location ends is less than the spacing between two installing holes.
Location structure comprises on the moulding dynamic model 1 sheathed holddown spring 7, the fixing location briquetting 8 in guide post 6 lower ends on the upper end periphery that is in two guide post 6, guide posts 6 between the paw 5 of along the vertical direction guiding assembling, the lower end of holddown spring 7 is fixed on guide post 6, and the upper end is fixed on the moulding dynamic model 1; Stretch out from the below of installing hole the lower end of guide post 6, and extension is provided with the location briquetting 8 of the origin reference location end below that is in paw 5, and the lower surface of location briquetting 8 is and the identical adaptive plane of the origin reference location face of moulding carcass 3.
The utility model in use, first with the plastic plate 9(that cuts out ABS sheet material for example) be placed on the origin reference location face of moulding carcass 3, and moulding dynamic model 1 is pressed down, the lower surface of location briquetting 8 is pressed on the plate face of plastic plate 9; Then start calandria 4 energising heating, plastic plate 9 parts that are heated to calandria 4 are subjected to thermal softening; Then continue moulding dynamic model 1 is pressed down, location briquetting 8 overcomes the elastic force of holddown spring 7, moulding dynamic model 1 moves up relatively, simultaneously plastic plate 9 is applied larger thrust, the origin reference location end of paw 5 can be subject to locating the block power that makes progress that briquetting 8 applies simultaneously, the moulding positioning end of paw 5 is rotated to the direction of the moulding locating surface of close moulding carcass 3, make plastic plate 9 under the acting in conjunction of location briquetting 8 and paw 5, to the direction bending of parcel moulding carcass 3, finish the processing and forming of column.
Present embodiment is by relative motion upper, carcass pedestal 2, and processing and forming just can be processed into plastic plate 9 column that needs successively, has shortened technological process and the production cycle of processing and forming, has improved the production efficiency of column processing.Paw 5 is installed on the moulding dynamic model 1, moulding carcass 3 is installed on the carcass pedestal 2, upper, carcass pedestal 2 can be installed on forcing press or the stamping machine and use, thereby so that the utility model compact conformation solves the discrete problem of plastic plate 9 forming die structures in the prior art.
In the above-described embodiments, the location briquetting is to the thrust of plastic plate, rely on the downward active force of holddown spring to guarantee, in other embodiments, also can remove this holddown spring, because in the process that the moulding dynamic model presses down, when the moulding positioning end of paw is pressed the overhanging portion of plastic plate downwards before, the origin reference location end of paw has begun the location briquetting is applied downward thrust, therefore need not holddown spring and compress the location briquetting by guide post, the origin reference location end of paw also can be pressed on the location briquetting on the plate face of plastic plate.
In the above-described embodiments, being shaped as of paw is L shaped, in other embodiments, the shape of paw also can be C shape, an end edge that only needs to guarantee paw is on the origin reference location face of moulding carcass and gets final product, because in use, plastic plate treat that bending part is under the heat effect of calandria, other positions than plastic plate are soft, therefore only need to apply at the hanging part of plastic plate the bending that downward active force just can be realized plastic plate, and in the bending process, the moulding locating surface of moulding carcass can play the spacing effect of block, restriction plastic plate bending degree guarantees the shape after plastic plate bends.
In the above-described embodiments, the moulding carcass be shaped as cube, in other embodiments, the shape of cross section of moulding carcass also can be circular, trapezoidal or other regular polygons, and the transition face at the corner location place of corresponding moulding carcass is the bending locating surface of moulding carcass.
In the above-described embodiments, be equiped with calandria in the moulding carcass, plastic plate is treated the bending part heating, thereby make plastic plate produce bending on the basis of plastic deformation, avoid directly bending the brittle fracture that plastic plate brings, in other embodiments, when the material of sheet material is that rigidity is preferably during material, such as steel plate or aluminium sheet, then can in the moulding carcass, not install calandria, by paw and direct bending sheets of cooperating of moulding carcass.
The embodiment of plate edge folding machine structure of the present utility model: as depicted in figs. 1 and 2, in the above-described embodiments, describe in detail about the concrete structure of plate edge folding machine structure, therefore repeat no more in an embodiment.But in the above-described embodiments, be provided with two paws in order to process column at patrix, therefore in the present embodiment, this edge-folding mechanism is in order to finish the purpose with the sheet material bending, so only needs to guarantee to have a paw in the present embodiment and just can finish purpose with the sheet material bending.
