A kind of feeding pressure mechanism and plank high-speed cutting machine
Technical field
The present invention relates to a kind of feeding pressure mechanism of plank and plank high-speed cutting machines.
Background technology
The equipment for being used for the steel plate that cutting thickness is thicker, specification is larger on the market has very much, such as gantry sawing machine, plank are cut
Cutting mill etc..Either which kind of plate cutting equipment is required for going to compress plank then again by material pressing device when cutting plank
Cutting.If Publication No. CN203541727U discloses a kind of plank high speed sawing multigraph press, especially in attached drawing and specification
As can be seen that its material pressing device includes three oil cylinders and binder crossbeam in appearance, binder crossbeam is connected with the mandril of three oil cylinders,
Binder crossbeam is driven to carry out binder jointly by three oil cylinders when binder.Its binder principle is made using the lower surface of binder crossbeam
With on the upper surface of plank, can only compressing the more smooth plank in upper surface, but plank in the actual production process
Upper surface may there is a situation where uneven, however existing this material pressing device can only push down upper table during binder
The peak in face;In such cases if carrying out cutting plank, it can make plank shakes to play obstruction to cutting, plot is light
It can make the cut surface of product after cutting is not smooth enough to scrap when micro-, plank shakes in cutting when of a serious nature hits saw blade
So that saw blade is scrapped.
So design it is a kind of so that the feeding pressure mechanism of more consolidation pressed of plank this just become those skilled in the art
Urgent problem.
Invention content
The invention mainly solves the technical problem of providing a kind of more stable feeding pressure mechanisms for keeping plank clamped
And plank high-speed cutting machine.
The purpose of the present invention is realized by following scheme:A kind of feeding pressure mechanism comprising be equipped with the rack of workbench, work
Make platform for placing plank;Wherein, further include crossbeam, hydraulic system and the oil cylinder I being located above workbench;Crossbeam with
Rack is connected, and the quantity of oil cylinder I is several, is fixed on crossbeam and is set in distance between each oil cylinder I, each oil cylinder I
Mandril driven by hydraulic system after be against plank upper surface regional area on;Further include driving source, crossbeam is in rack
Sliding setting, source driven are driven towards workbench sliding.
Due in the prior art, being to carry out binder using hydraulic oil cylinder driving binder crossbeam, acting surface is the whole of binder crossbeam
A face, if uneven situation occurs in the upper surface of plank, binder crossbeam can only push down the peak of plank upper surface, institute
Stress point with plank upper surface is only peak, therefore the situation of binder shakiness can be caused to occur.And use the present invention such
Structure, due to being pressed to the upper surface of plank using multiple compressing units, when pressing, each compressing unit was against and plank
The local location of upper surface, to play multipoint mode pressing, even and if the pressing structure plank upper surface of this multipoint mode is recessed
The structure of convex injustice, what can also be pressed is very tight, is conducive to the cutting of plank, to improve yield rate.
Using oil cylinder as compressing unit, the pressure actuation for being primarily due to oil cylinder is relatively stable, when its mandril is against plate
It is relatively stable to the pressure of plank upper surface when the upper surface of material, be conducive to compress plank.
It adopts the structure, the process of binder is, the mandril of each oil cylinder I first stretches under the action of hydraulic system
To maximum value, then driving source drive crossbeam sliding makes the mandril of each oil cylinder I gradually close to plank, when each oil cylinder I
When mandril acts on plank upper surface, under the reaction force of plank, it is most suitable flexible that the mandril of each oil cylinder I bounces back to its
Amount compresses plank, if plank upper surface is uneven structure, the most suitable stroke of each oil cylinder I is different, plays
The significantly more efficient plank for compressing uneven structure.By crossbeam towards the sliding of workbench, I mandril of oil cylinder can be reduced
The requirement of required overhang so that the pressure when acting on plank upper surface of oil cylinder I is more stablized.
Wherein, further include spring identical with I quantity of oil cylinder, the cylinder body of oil cylinder I is fixed on crossbeam, and mandril is by cylinder body
Lower face is stretched out, and spring pocket is set to one end on cylinder body and is fixed with cylinder body, and the other end is fixed with mandril.
Wherein, cylinder body includes fixed part and narrow portion, and the one side of fixed part and crossbeam towards workbench is fixed, mandril by
The lower face of narrow portion is stretched out, and spring pocket is set to one end in narrow portion and is welded with fixed part, and the other end is welded with mandril.
It adopts the structure, when mandril stretches out pressing plank, in reaction force and spring from plank upper surface
Reply force effect under, mandril can be made to snap back to the upper surface that most suitable stroke compresses plank.
Wherein, the driving source is oil cylinder II, and the crossbeam is pulled or pushed realization to move by oil cylinder II.
Driving source uses the design of oil cylinder II, the transmission performance for being mainly in view of oil cylinder relatively stable.
Wherein, the both ends of crossbeam are fixed with slider I, and rack is equipped with sliding rail, and slider I is arranged with sliding rail in sliding.
The design of slider I and sliding rail can improve stability when crossbeam sliding.
A kind of plank high-speed cutting machine comprising cutter device and driving device, the cutter device is by driving device
Driving is cut, wherein further includes above-mentioned feeding pressure mechanism.
It adopts the structure, the upper surface of plank is pressed using multiple compressing units, when pressing each compresses list
Member is against the local location with plank upper surface, to play multipoint mode pressing, even and if the pressing structure plate of this multipoint mode
Material upper surface is rough structure, and what can also be pressed is very tight, and cutter device is driven using driving device control after compression
Cutting plank is carried out, the cut surface for the product being cut into can be made more smooth, improves yield rate.
Wherein, driving device includes that the sliding block II in sliding setting, cutter device are fixed with sliding block II by sliding block with rack
II drives sliding;Cutter device includes saw blade box and the saw blade by motor-driven rotation, and saw blade is set in saw blade box and portion
Divide and is pierced by by saw blade box lower part;Further include clamping device, clamping device includes fixing bracket, power source and at least two fixture blocks;
Initial position when fixing bracket is fixed in rack and is moved positioned at saw blade, two fixture blocks are set on fixing bracket in erecting
It sets, two fixture blocks and fixing bracket are arranged in sliding, and two fixture blocks are mutually drawn close by driving source driving and are pierced by portion for be clamped saw blade
Two surfaces being divided to, when under the clamp position, there are minimum clearance d between two fixture blocks and saw blade surface, 0.5mm >=d >=
0.01mm。
Due to being easy to happen axial shaking when saw blade rotates, using the setting of clamping device, pass through power source drive two
A fixture block clamping saw blade close to each other is pierced by part, and (clamping is not pressed from both sides extremely herein, and refers between two fixture blocks and saw blade surface
There are minimum clearance d), and to reduce the shaking of saw blade under maximum degree, saw blade goes cutting plank to make plank again at this time
The face cut is more smooth, improves yield rate, strengthens the stability that lathe uses, extend the service life of saw blade.
Wherein, the power source is oil cylinder III, and III quantity of oil cylinder is identical as the quantity of fixture block, and fixture block is by corresponding oil cylinder III
Driving.
