Description
Technical field
The present invention provides a kind of functional steel panel automatic gas cutting machine, belongs to field of mechanical technique.
Background technology
Steel grating is the plate for being arranged in grid by certain spacing longitude and latitude by band steel and cross bar, is radially steel grating for band steel
Length, broadwise is cross bar, i.e. the width of steel grating.
At present, domestic steel grating is cut with two ways, machine cuts and gas flame cuttiug, and the height of machine cuts is big
In 30 millimeters of steel grating, the height of gas flame cuttiug cutting is less than 30 millimeters of thin-walled parts, and steel grating radical length is 6 meters, height
Do not waited from 25~75 millimeters, 3 millimeters of thickness, the steel grating of communications centre tooth is put in and machine cuts, the clamping device of use and cutting
Put on punch press, rule, gradually push ahead by hand, pin steps on the mode of control, brings problem to be：1st, efficiency is low, and 2, positioning accurate
Degree is low, 3, accumulated error it is big, 4, punching uniformity it is poor, 5, easily cause personal injury, because radical length is longer, on platform is rushed to
During preceding propulsion, swing is big, linearity is poor, and positioning precision is low.
The content of the invention
It is an object of the invention to provide a kind of functional steel panel automatic gas cutting machine, the feed mechanism controlled by PLC is used
Gear, rack engaged transmission, steel grating is adsorbed using magnetic field to be fixed, fixing device and cutter device not on the same face, just
Continuously produced in mechanization automatic assembly line, using PLC programming Controls, the precision of conveying is high, does not produce accumulated error, efficiency
It is high.
Realize that the technical scheme that foregoing invention effect is taken is:
A kind of functional steel panel automatic gas cutting machine, including frame, feed mechanism, cutting mechanism, switch board, its feature exist
In：Cutting mechanism is vertically moved up or down oil cylinder, dual force horizontal telescoping oil cylinder and cutting head by dual force and constituted, dual force
Be vertically moved up or down oil cylinder adjust cutting head the cutting-height from steel grating cut surface, for same specification steel grating cutting before can
One-time positioning, can both be manuallyd locate, can also on the basis of Cutting platform the cutting of input parameter adjust automatically cutting head it is high
The cutting to steel grating is realized in degree, the reciprocating motion of dual force horizontal telescoping oil cylinder, and dual force horizontal telescoping oil cylinder drives
Cutting head is moved, and each motion of cutting head is all cut accordingly, and cutting head is arranged on dual force and is vertically moved up or down oil cylinder
On, cutting head includes flame cutting head and disc rotary cutting knife, and the thickness of steel grating is from the mm of 25mm~75, gas flame cuttiug
Head is adapted to the steel grating that thickness is less than 30 mm, and the steel grating that thickness is more than 30 mm is cut with disc rotary cutting knife, steel grating
It is the plate for being arranged in grid by certain spacing longitude and latitude by band steel and cross bar, cross bar is placed on the semicircle set on band steel and rushes tooth
Inside it is welded, welding temperature is high, welds facial disfigurement, cause whole cutting surfaces out-of-flatness, the multifunctional numerical control used at present
Most of cutting machine uses gas flame cuttiug, and gas flame cuttiug can only steel grating of the cutting thickness less than 30 mm, steel grating split requirement
Precision is high, cut lengths ± deviation（Error is less than 5mm）, the deviation for the length cut every time is equidirectional, that is, is cut
Either length is overgauge entirely, or be minus deviation entirely, it has been disclosed that Multi-functional numerical control cutting machine, using gas flame cuttiug, steel lattice
Plate be placed on cutting stand on it is motionless, numerical control cutting machine carries out three seats incessantly by the flame cutting head of three coordinate controls
Position motion is demarcated, locating speed is slow, and efficiency is low, steel grating, which is placed on cutting stand, does not have clamping device, higher flame temperature
Degree, cutting end face can be deformed upon afterwards to the cold, cause steel grating to be subjected to displacement, and cutting accuracy be influenceed, secondly, for cutting thickness
More than 30 mm steel grating, cut using numerical control disc rotary cutting knife, numerical controlled machinery cutting machine by three coordinate controls disk rotary
Turn cutting knife, steel grating is placed on cutting stand using mechanical and hydraulic clamp, is in disc rotary cutting knife same
One cut surface, disc rotary cutting knife is interfered with clamping device, and the solder side of steel grating is uneven, and clamping device is located at welding
On face, 6 meters of steel grating length, according to actual requirement in engineering, it is necessary to cut different length, clamping device is needed on cut surface
There is many places setting, clamping device is located at sustained height face, simultaneously clamped on, and clamps face discontinuity, causes steel grating in the ceding of Taiwan
Position is offset on frame, influences cutting accuracy, and the steel grating after cutting does not reach technical requirements, and multiple clamping is time-consuming, production
Efficiency is low, it is impossible to realize worked continuously by automation, and this technology uses and guide rail is provided with frame, and feed mechanism is by feeding
Frame, gear, rack and servomotor, are provided with sliding sleeve, guide rail is through in sliding sleeve, on a face of cradle on cradle
Place and electromagnet is installed on steel grating, another face, cradle the selection of material is stainless steel or potassium steel, and electromagnet is not adsorbed
Cradle, electromagnet energization absorption steel grating is securely seated between on cradle, the tangential force and disk of disc rotary cutting knife
The bounce of rotary cutter will not cause position to offset steel grating, and cutting accuracy is high, and the size of electromagnet magnetic field force can pass through
Knob regulation on switch board, gear is fixed in frame, and servomotor output end couples with gear, wheel and rack engagement,
Pinion rotation drives to slide in guide rail and moved, and then drives cradle motion, and switch board is provided with PLC and electrical equipment control member
Part, feed mechanism and cutting mechanism are controlled by PLC, and feed mechanism controls its total movement process by PLC, each
The job order of station is harmonious, is not disturbed by human factor, and by formula L=θ π R/180, arc length is equal to pinion rotation angle
Degree be multiplied by π be multiplied by gear radius divided by 180 °, error depends on π values, and error corrects in a program, and θ value is gear
Rotational angle, circles i.e. 360 °, n/360 ° of circle of decile, and n is the number of degrees of gear actual rotation, and proximity switch is installed in frame,
Before cutting, the hand push button on switch board carries out just positioning to steel grating, is just off working state after the completion of positioning, first cuts
Delivery end part, is named flush, after the completion of one-time positioning, the cutting that disc rotary cutting knife only moves back and forth, it is not necessary to fixed again
Position, the precision of cutting is determined by PLC control feed mechanisms, then inputs the numerical value of Cutting Length, is cut automatically by PLC controls
Cut, continuous mechanized operation can be realized, feed mechanism precision is high, and electromagnet clamping device can realize Quick-clamped.
The present invention compared with prior art, has the following advantages that.
1st, transmit steady using pinion and rack, clamped one time positioning can continuous several times punching, positioning precision height, punching
Hole precision is high, no accumulated error.
2nd, its total movement process is controlled by PLC, the job order of each station is harmonious, work effect
Rate is high.
