Description
Technical field
The utility model relates to sheet fabrication field, particularly relates to a kind of process equipment of many curved surfaces sheet material.
Background technology
Usual metal skin adopts stretching-machine to carry out stretching to sheet metal to obtain, stretching-machine mainly comprises the equally distributed lift be fixed on pedestal, the steel collet being fixed on lift piston rod part and the curve mold be placed on steel collet, by control signal notice magnetic valve break-make, take hydraulic oil as pressure conduction medium, the lifting of control piston bar, to drive curve mold extrusion metal sheet material, sheet metal edge is subject to draw-off mechanism and fixes tractive, forms the curve form matched with mold profile after being squeezed.
Utilizing hyperboloid die drawn hyperbolic covering, for overcoming the structural stress of sheet metal, needing significantly to improve lift power output, in order to adapt to processing variety, just needing upgrading stretching-machine power.And there is crumple effect in metal, once exceed sheet metal bear the limit can rapid deformation, this proposes to be strict with to lift output power again, makes covering impaired, curve mold of even wearing and tearing once process bad meeting.Both of these case all can increase production cost, and yields can be affected.
Utility model content
The purpose of this utility model is to provide a kind of continuous heating skin drawing machine, solves the technical problem that existing skin drawing lift power controls not easily to realize.
Continuous heating skin drawing machine of the present utility model, comprise pedestal, on the top of pedestal sidewall, the stay rod that vertical fixed position is relative, arranges fixed frame on base central stay rod sidewall, is fixed with towards the elastic force pulley of opposing sidewalls in fixed frame, opposing elastic force pulley in opposing sidewalls is circumferentially wound around insulation cable, insulation cable is formed and intersects, and crosspoint adopts fastener to fix, and forms fixing grid;
Fix firing equipment in the fastener lower end in crosspoint, the heat output of fixing firing equipment or induction end are towards base bottom.
Described firing equipment is one or both in acetylene flame shower nozzle, gas burner shower nozzle and electromagnetic heating coil.
The power cable of described firing equipment, gas conduct pipe, holding wire are wrapped in the stay rod of insulation cable being guided wall into.
Described fastener comprises the fixing ambroin of two-layer squeezed tight.
Continuous heating skin drawing machine of the present utility model is started with from the rigidity of softening metal skin and is utilized heater to heat the region that metal sheeting design stress process is concentrated, softening sheet metal, reduce structural stress, after processing puts in place, stress recovery is steady.The metal skin internal stress utilizing this continuous heating skin drawing machine to be formed is even, through long-time not yielding.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model continuous heating skin drawing machine;
Fig. 2 is the structural representation of the utility model continuous heating skin drawing machine heating arrangements.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As depicted in figs. 1 and 2, in the present embodiment, the pedestal 01 of continuous heating skin drawing machine is the cube that rectangle blind hole is offered at a center, upper surface, lift 02 is fixed in the bottom of blind hole, the piston rod part of lift 02 is fixed on the bottom of steel collet 03, mould 04 is arranged on the top of steel collet 03, and the edge of sheet metal 06 is fixed on the top of pedestal 01 wall by hold assembly 05;
On the top of pedestal 01 wall, vertically fixing stay rod 11, the quantity of the stay rod 11 on left and right sidewall top is corresponding with position, and the quantity of the stay rod 11 on forward and backward sidewall top is corresponding with position; Stay rod 11 arranges fixed frame on the sidewall of blind hole (base central), elastic force pulley 12 is fixed with in fixed frame, running through the elastomeric material two ends that elastic force pulley 12 axis is fixed is fixed on framework, make elastic force pulley 12 periphery towards opposing sidewalls, elastic force pulley 12 circumference is stressed, circumferentially produce rotation, stressed elimination elastomeric material reinstatement produces and rotates backward;
The elastic force pulley 12 relative at left and right sidewall is circumferentially wound around insulation cable 13, the elastic force pulley 12 relative at front-rear side walls is circumferentially wound around insulation cable, formation longitude and latitude intersects, crosspoint adopt fastener 14 (after upper and lower two-layer insulated plastic flitch dissolves cooling, or upper and lower two-layer ambroin block coordinates adhesive bond) fixing, make crosspoint form fixing grid;
A firing equipment 15 is fixed in fastener 14 lower end on each crosspoint, and the power cable of firing equipment 15, holding wire or gas conduct pipe are wrapped in the stay rod 11 of insulation cable 13 being guided wall into; Firing equipment 15 can select acetylene flame shower nozzle or gas burner shower nozzle, and can also select electromagnetic heating coil, electromagnetic heating coil utilizes high frequency electric, and reliability is high, concentration of energy, and handling safety is first-selected, and heat output or induction end are bottom pedestal 01.Firing equipment can combine setting.
In actual applications, steel collet 03 is by lift 02 ejection, driven mold 04 is sheet metal (normally steel plate) upwardly, sheet metal is stretch bending thereupon, contact the firing equipment 15 of grid surrounding further, the position that in BENDING PROCESS, structural stress is strong can be obtained according to precalculating, the firing equipment 15 started in stretch bending process near relevant position carries out local heat and softens, in stretch bending process, grid surface, longitude and latitude cable is by elastic force pulley 12 folding and unfolding.When stretching puts in place, the internal stress of the position reservation that original structure stress is strong can significantly reduce.
Heating in stretch bending process is relevant to the profile shapes of final molding for opportunity, utilizes this continuous heating skin drawing machine to coordinate with upper-level control system, can realize optimum processing form and lowest energy consumption.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
