It is fixed below transverse baffle and longitudinal baffle, transverse baffle and longitudinal baffle surface are equipped with graduation mark, transverse baffle and longitudinal direction
Height of baffle plate is higher than busbar thickness so that for loaded cylinder energy storage, pillar upper end is equipped with tooth row, is equipped with force application board in tooth row side, applies
Guiding mechanism of the power plate through moving up and down is connected with pillar, and force application board is equipped with transmission gear, and transmission gear is mutually nibbled with tooth row
Crossed belt moves force application board and moves up and down, and transmission gear is equipped with the pull rod for being able to drive transmission gear rotation, is equipped with below force application board
Loaded cylinder, guiding mechanism of the loaded cylinder through moving up and down are connected with pillar, and connecting rod insert port, loaded cylinder are equipped with above loaded cylinder
Lower section is equipped with opening, is equipped with piston inside loaded cylinder, piston is connected through energy-stored spring, connecting rod with force application board, piston lower surface
Equipped with mounting groove, piston side is equipped with mold fixation hole and piston energy storage pin hole, and the spiral shell of fixing mould is equipped in mold fixation hole
Bolt, mold upper end are equipped with the installing handle matched with mounting groove, and installing handle is equipped with fixed card slot, and mold installing handle is inserted into peace
Cooperation through bolt and fixed card slot in tankage makes mold be connected with piston, and mold is equipped with adjustable guiding mounting hole,
Being oriented to mounting hole is in Phillips-type, and guiding mounting hole is inverted T font in the section of mould inside, and punch-holder shank passes through guiding mounting hole
It is connected through gasket, nut with mold, energy storage cylinder surfaces are equipped with loaded cylinder pin hole and removal hole, and energy storage retaining pin one end is through energy storage
Cylinder pin hole, which is inserted into piston energy storage pin hole, makes piston be connected with loaded cylinder, and the energy storage retaining pin other end is connected with guide rod,
Lower end of the guide rod portion is connected through pin shaft with the lug that energy storage cylinder surfaces are arranged in, and spring is also connected between guide rod and loaded cylinder,
Guide rod upper end is matched with down-pressed pole lower end, and down-pressed pole upper end is connected with connecting rod, and connecting rod, which moves down, drives down-pressed pole to move down, and is pushed
Bar, which moves down, makes guide rod that energy storage retaining pin be driven to open outward.
Spring protection cover is equipped on the outside of the energy-stored spring, spring protection cover is connected to guarantee energy-stored spring with connecting rod
It does not shift in thermal energy storage process, energy storage more energy.
The guiding mechanism that force application board can be made to move up and down is a kind of semi-enclosed sleeve, and sleeve is mounted on pillar
On, sleeve openings size is identical as tooth row size, and force application board is connected with the sleeve of tooth row two sides.
The guiding mechanism that force application board can be made to move up and down is equipped with sliding slot, force positioned at the two sides of tooth row on pillar

Connecting rod, which drives loaded cylinder to move downward, contradicts loaded cylinder bottom on transverse baffle and longitudinal baffle, at this time mold and punching head and mother
There is certain distance between row, then the high-voltage energy storage spring inside loaded cylinder is compressed under connecting rod effect, while down-pressed pole
Conflict is moved downward in energy storage retaining pin, and the energy storage retaining pin on loaded cylinder will limit the movement of down-pressed pole, work as loaded cylinder
When internal energy-stored spring stored energy reaches the limit values, down-pressed pole can flick outward guide rod, and piston loses at this time
The constraint of energy storage retaining pin, thus abrupt release spring energy, it is quick downwards that this energy will drive the mold inside loaded cylinder
Movement, to complete the work of the punching perforating on busbar, mold passes through waste material caused by busbar punching useless on pedestal
Material through hole is fallen, after punching, pull pull rod make transmission gear drive force application board move upwards, make force application board drive connecting rod to
Upper movement, connecting rod, which moves upwards, drives loaded cylinder to move upwards, and piston moves upwards under the pulling force effect of spring at this time, works as work
When plug energy storage pin hole is reached with loaded cylinder pin hole sustained height, energy storage retaining pin passes through loaded cylinder pin hole again under the action of the spring
It is inserted into piston energy storage pin hole, piston is made to be fixed to initial position, punching next time is waited, when needing to replace to mold
When cleaning, removal hole and mold fixation hole are passed through using screwdriver, mould release is got off by rotation fixed screw.
The usefulness of the invention is, this quick hole punched device structure of busbar is simple and stable structure, device volume
Small easy to carry, mold controllability is high and easy for installation, can more mold exchange or adjustment forcer position at any time, reduce at
This, busbar positioning accuracy is high, can be widely applied in the processing of power supply unit scene and production process.
