Technical field
The utility model relates to mechanical field, particularly relates to a kind of automatically controlled turning mould thermoforming machine.
Background technology
Simultaneously conjugate cam controls a driven member by two panels cam, and the freedom of driven member both direction is all limited, so the two panels cam of conjugation must strict guarantee one enter to move back, you move back me and enter, otherwise mechanism can stuck or damage.Advantage: the characteristics of motion of driven member is unrestricted, can choose arbitrarily within the scope of 360o.Shortcoming: complicated structure.The design of tradition conjugate cam mainly adopts diagram method and analytic method, diagram method according to the general principle of reversal process, by mapping mode pointwise matching cam contour; Analytic method is by mechanism's geometrical relationship, utilizes formulae discovery cam contour coordinate.Analytic method comparatively diagram method is more accurate, but in practical set-up design process, the contour shape of conjugate cam and the characteristics of motion depend primarily on the characteristics of motion of mechanism's terminal driven member, and middle driven member is formed by Mechanism Combinations such as connecting rods often.When calculating cam profile curve, the direct driven member of the cam that needs to derive according to the motion of terminal driven member, computational process is comparatively complicated.
Current turning mould thermoforming machine switching mechanism used is the form of conjugate cam; the motion of turning mould thermoforming machine workbench is divided into upset and two actions that move up and down; rotary movement should wait after die sinking to certain distance could action; otherwise upper/lower die can collide; the backhaul function of conjugate cam will be utilized simultaneously; make workbench by fixing track backhaul, not so also can produce collision, can not by fixing orbiting motion.And the amendment of track produces impact greatly by the design of conjugate cam, realize very complicated.
Because the design and manufacture required precision of conjugate cam is higher, be difficult to after cam wear revise, be difficult to safeguard and assembling, movement locus and rule cannot be revised in work, impulse stroke and flip angle cannot be changed, greatly restrict the application prospect of turning mould thermoforming machine.
Utility model content
The purpose of this utility model is to provide a kind of automatically controlled turning mould thermoforming machine, adopts automatically controlled mode to realize the upset of workbench, solves existing conjugate cam Problems existing.
In order to realize above-mentioned object, adopt following technical scheme: a kind of automatically controlled turning mould thermoforming machine, comprise fixed form, cope match-plate pattern, guide pillar and switching mechanism, described fixed form is arranged on guide pillar lower end, cope match-plate pattern is arranged on guide pillar upper end, described switching mechanism comprises moving platen, bearing block and the servomotor be connected successively, rotating shaft, turn-over form, switching mechanism is arranged on guide pillar by moving platen, bearing block is arranged on moving platen, rotating shaft is arranged on bearing block, described turn-over form is provided with bed die, the corresponding bed die of cope match-plate pattern is provided with mold.Fixed form is used for whole table apparatus to fix on the ground, and guide pillar plays switching mechanism and guides the effect of moving direction, moves up and down by switching mechanism the folding realizing mold and bed die.Servomotor can be arranged on moving platen or on bearing block, adopt the upset of Serve Motor Control turn-over form, by the function of electric cam of having programmed, realize writing of movement locus, adopt different programs to realize the change of impulse stroke and the change of flip angle.
Described moving platen is provided with buffer unit, buffer unit plays the effect of buffering to turn-over form, because turn-over form weight is larger, operating rate is very fast, the moment of inertia produced during thermoforming is comparatively large, can reduce impact by buffer unit, when turn-over form be turned to contact with buffer unit time, cushioned by buffer unit, realize the steady upset of turn-over form.
Described buffer unit is cylinder, and the corresponding cylinder of described turn-over form is provided with cylinder cushion block.Employing cylinder coordinates with cylinder cushion block, and can also play the effect of boosting while buffering, when recovering level after turn-over form has overturn, cylinder starts simultaneously, produces thrust to turn-over form, realizes accelerating startup, reduces staring torque.Conveniently being contacting and separating and the mutual motion of contact process of cylinder and cylinder cushion block, the contact surface of cylinder and cylinder cushion block adopts sphere-contact.
Described moving platen is connected with up-down drive device, is realized the folding of mold and bed die by the active force of up-down drive device to moving platen.Described up-down drive device can adopt the oil cylinder be arranged on fixed form.
Described switching mechanism also comprises decelerator, described servomotor connection reducer, decelerator connection rotating shaft.Reduced drive shaft again after the rotating speed of servomotor by decelerator, make turn-over form can obtain the rotating speed needed.
Described rotating shaft is provided with photoelectric encoder, and photoelectric encoder is arranged on one end of rotating shaft, detects the actual rotational angle of turn-over form, by the information feed back that detects to control system, ensures that turn-over form accurately puts in place, thus realizes accurately location.
Described rotating shaft is provided with brake, and brake is arranged on one end of rotating shaft, and the carrying out during for putting in place to turn-over form upset is braked, and reduces inertia impact.
Described rotating shaft is provided with rolling bearing, and rolling bearing is arranged on bearing block.
Described rotating shaft is connected with turn-over form with double nut by key.
Compared with prior art, the utility model adopts the mode of automatically controlled upset, by the upset of Serve Motor Control turn-over form, servomotor is utilized to develop the function of electric cam, because electric cam adopts the method for programming to realize the movement locus of cam, flexibly and easily, impulse stroke and flip angle can be changed, adapt to different requirements, and easy to maintenance, manufacture simple, have wide practical use.
