Description
Technical field
The invention belongs to materials processing technology fields, and in particular to a kind of Recombined bamboo non-uniform member manufacture mold.
Background technology
Bamboo wood relies on the excellent mechanical properties such as longitudinal strength is big, hardness is high, resourceful renewable is strong, is nature
One of highest material of efficiency in boundary, the Recombined bamboo formed by recombination cold pressing or hot pressing are widely used in building and structure
With material, tensile strength and compression strength are considerably beyond common wood.And now the technique of the prismatic Recombined bamboo of production more at
Ripe, in order to meet the needs of multi-section form beam, column etc. in building structure, how to suppress the Recombined bamboo component of different cross section becomes
One technological difficulties.
Existing Recombined bamboo cold stamping die type is single, and a kind of mold can only suppress a kind of Recombined bamboo of sectional dimension, and
Circle etc. is difficult to realize with cambered component manufacture mold, and does not have versatility, it is difficult to the need for adapting to variable cross-section, becoming size
It asks.Such as Chinese patent CN203636942U, disclose a kind of cylindrical recombining bamboo cold stamping die, including bottom, two symmetrically set
The baffle and cover board set, two baffles are fixed together with pedestal respectively, and cover board is arranged between baffle, passes through pin fixing lock
Tightly；For another example, Chinese patent CN105835206A discloses a kind of cylinder recombining bamboo production method and its molding machine, mould
Tool is made of cope plate, lower template and end cap, and square window is provided on cope plate, by drive roller sets thus bamboo wood is sent into chamber
Body is pressurizeed by one piece of arc pressuring plate, and raw material is necessary for the consistent long thin bamboo strips used for weaving item of equilateral or isosceles triangle of specification.Above-mentioned mold
Do not have the changeability of press members section and size, and the baffle in the former mold and pedestal separation, in pressing process
The loosening of two side shields may result in the deformation of test specimen, and cross section is not regular circular, and requirement of the latter to raw material has
Limitation, process is complex, does not have versatility.
Invention content
The object of the present invention is to provide a kind of Recombined bamboo non-uniform members to manufacture mold, has different cross section chamber by replacement
The core model of body, realizes the compacting of different cross section Recombined bamboo component, one module multiple usages, flexibly convenient, and can batch production make, bamboo wood
Disposal pressed moulding, easy to operate, structure is uniform, and anchoring is reliable and secure, is effectively improved production efficiency.
The technical scheme is that：A kind of Recombined bamboo non-uniform member manufacture mold, including external mold, core model and locking pin
Bolt, external mold U-shaped profile, two side surface upper parts of external mold symmetrically open up two pairs or more keyholes, core model by a pair of of top board and
The upper and lower pairing of lower plate is constituted, and core model can be freely detached from and replace with external mold, core model be filled in inside external mold and its outer wall with outside
The inner wall of mould is bonded, and there are one section cavity sealed around, the inside of cavity for formation between the top board and lower plate of core model
Hollow, hollow section has transformable shape and transformable size, the vertical axis of cavity and the vertical axis direction of core model
Unanimously, external mold, core model are fixed locking by locking pin by the keyhole of external mold both sides, and Recombined bamboo variable cross-section bamboo component to be processed fills
Completely it is compacted at the cavity of core model.
In structure of the invention, external mold immobilizes, and core model can flexibly replace adjustment, and the hollow section of core model, which has, can change
Shape and transformable size, simple in structure, flexible, convenient, external mold one module multiple usages, only need to replace different core models, you can pressure
The Recombined bamboo component of different cross section shape and size processed, and external mold, core model closed are good, do not have specific limitation for raw material,
Strong applicability does not change existing Recombined bamboo drawing method in the market.
The top board bottom is equipped with groove, the corresponding groove that same shape, size are equipped on lower plate top, groove
It is the one kind for half polygonal grooves that semi-circular recesses, half rectangular recess, half elliptic groove or number of edges are more than, top board is under
The upper and lower pairing of bottom plate forms the cavity that a section surrounding is closed completely after closing.
The hollow section of the cavity is one kind of the polygon of circle, rectangle, ellipse or number of edges more than 4.
The cavity of the core model has transformable shape and transformable size, by changing top board and lower plate
Groove shape, size, you can compacting different shape and size Recombined bamboo non-uniform member.
The top board is one kind of solid top board or ribbed stiffener top board, and lower plate is solid lower plate or puts more energy into
One kind of rib lower plate, to reduce the dead weight of core model, the preferential form for selecting ribbed stiffener top board and ribbed stiffener lower plate.
Both sides length direction interval dispersed placement of the keyhole along external mold.
The ribbed stiffener top board and ribbed stiffener lower plate is vertical with vertical axis along longitudinally spaced setting two or more
Ribbed stiffener.
When Recombined bamboo non-uniform member suppresses implementation, lower plate is first placed in external mold, then by loose impregnation thin bamboo strips used for weaving
Item or bamboo fibre assemblies are disposably put into the semi-circular recesses of lower plate, are pressed into top board, are made loose impregnation thin bamboo strips used for weaving item
Or the cavity that bamboo fibre assemblies are formed full of top board with lower plate tight closure, it is inserted into locking along row's keyhole of external mold
Pin fixes top board so that test specimen and mold etc. are finally integrally moved to fog room, heated by core model integral locking in external mold
Solidification, demoulding, forms a kind of circular cross-section Recombined bamboo component.
Advantage of the present invention is notable, has the advantages that：
(1) present invention realize different cross section Recombined bamboo component production, can be directly used in building structure it is prismatic,
Cylindrical, ellipse and polygon beam, column etc., instead of traditional log.
(2) it by the core model of cavity of the replacement with different cross section shape and size, places it in external mold, you can compacting
The Recombined bamboo component of different cross section, simple in structure, easy to operate, external mold one module multiple usages greatly improve production efficiency.
(3) external mold immobilizes, and core model freely can be detached from and replace, and die change is efficient, greatly improve compacting
The versatility of mold.
(4) raw material are not particularly limited, can are thin bamboo strips used for weaving item or bamboo fibre assemblies, are not necessarily to special processing,
Compression moulding, even density, integral strength are high.
