Structure enters mistake, meets the demand of small-power output large-tonnage pressure.
The object of the present invention is achieved like this:
A kind of cut assembly for plastic thermal molding equipment, including connecting assembly and the identical group of cranking arm of two groups of structures,
Group of cranking arm includes that cranking arm in top and cranks arm in bottom, and cranking arm in top and cranks arm and be articulated and connected in bottom, connects assembly and is positioned at two suite arms
Group in the middle of, connect assembly both sides respectively crank arm with both sides group the junction that cranking arm in top and cranks arm in bottom be articulated and connected.
Cranking arm and include upper bed-plate and some upper side torque arm in described top, lower bent lever includes lower bottom base and some bottoms layback
Arm, the upper end of upper side torque arm is articulated and connected with upper bed-plate, the lower end of upper side torque arm and the upper end thereof of lower side torque arm, under
The lower end of portion's layback arm is hinged with lower bottom base.
Described upper bed-plate and lower bottom base are provided with some slots, and the upper end of upper side torque arm and the lower end of lower side torque arm are divided
Other intercalation is in slot.
Described connection assembly includes big contiguous block and two little contiguous blocks, and little contiguous block is respectively hinged at the two of big contiguous block
Side, the junction that cranking arm in top and cranks arm in bottom of the group of cranking arm with both sides respectively of little contiguous block is articulated and connected.
The assembly that cuts of described plastic thermal molding equipment includes power set, and the outfan of power set connects big contiguous block
And drive big contiguous block to move up and down.
Described power set are hydraulic cylinder.
Described power set include motor and accurate lead screw, and the outfan of motor connects big contiguous block by accurate lead screw.
Described plastic thermal molding equipment cut assembly include guidance set, guidance set include the axis of guides in the middle of two,
Axis of guide location-plate and axis of guide fagging, the lower end of the middle axis of guide is fixed even with axis of guide location-plate after big contiguous block
Connect, both sides crank arm group top and axis of guide location-plate by axis of guide fagging set up connect.
The present invention compared with prior art, has the advantages that the present invention's is simple and compact for structure, the present invention without
Use large-tonnage oil cylinder, can conveniently connect the standard small oil cylinder on market or motor-driven screw mandrel or electric cylinder, significantly drop
Low dynamical system cost and control system cost, such that it is able to more easily carry out integrated with automation equipment, meet variable
The power-assisted demand being incremented by, i.e. more to end of travel, strength is the biggest, thus well solves small-power power and cannot export big ton
The problem of position pressure, installs easy maintenance, is suitable to promote and batch production.
Accompanying drawing explanation
Fig. 1 is structural representation when cutting assembly strength maximum of the present invention；
Fig. 2 is structural representation when cutting assembly strength minimum of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the specific embodiment of the invention is described in further detail.
The present embodiment is a kind of cuts assembly for plastic thermal molding equipment, including connecting assembly and two groups of structures are identical
Cranking arm group, group of cranking arm includes that cranking arm in top and cranks arm in bottom, and cranking arm in top and cranks arm and be articulated and connected in bottom, connects assembly and is positioned at two
In the middle of suite arm group, connect assembly both sides respectively crank arm with both sides group the hinged company in the junction that cranking arm in top and cranks arm in bottom
Connect, described in crank arm group lower end cut-out plate is installed, the lower surface of cut-out plate is provided with cutting knife.
Cranking arm and include upper bed-plate 1 and two upper side torque arm 2 in described top, lower bent lever includes lower bottom base 5 and two bottoms
Layback arm 3, the upper end of upper side torque arm 2 is articulated and connected with upper bed-plate 1, and the lower end of upper side torque arm 2 is upper with lower side torque arm 3
