As research background is introduced, exist in the prior art that cutting mode efficiency is low, and mismachining tolerance is big, cutting it is steady
Qualitative difference, and mass ratio is relatively low；And a kind of composite board carborundum line cutting machines of Application No. CN201610804880.7,
Its Wire-conveying mechanism of quick walk is more complicated, and processing and debugging is difficult, uneconomical, and during work, heap silk and sand line tension are easily formed in incision
It is excessive, cause frequent fracture of wire, in order to solve technical problem as above, present applicant proposes a kind of manual carborundum line cutting machine.
1 present patent application is described further to Figure 15 and embodiment below in conjunction with the accompanying drawings：
Fig. 1 is composite board carborundum line cutting machine General Arrangement, mainly there is following sections：By loading drive gear
Put, crank block guide-bar mechanism, take-up and pay-off device, fixed retainer and floating material pressing device, Wire-conveying mechanism of quick walk, stationary work-table and bed
Body forms；
One motor is installed on lathe bed, the motor driving driving gear rotation, the driving gear and two
The equal working gear of structure size engages, and phase difference 180 degree and eccentricity phase are provided with described two working gears
Deng two crank axles, two crank axles are connected respectively to a top shoe guide rod and sliding block guide rod by rolling bearing respectively
On；Have take-up and pay-off device on the top shoe guide rod and sliding block guide rod, for fix carborundum line, replace carborundum line and
Change the active section of carborundum line；The fixation material-supporting device is installed on stationary work-table, the floating material pressing device
On fuselage；Fixed material-supporting device and floating material pressing device are used to push down nonmetal plate, non-in cutting process to reduce
The vibration of sheet metal；Being cut feeding, blanking and the feed motion of plate can be completed by manual operation.
The composite board carborundum line cutting machine course of work：Motor drive driving gear, allow respectively with the gear,
Two of lower engagement turn to the working gear rotating Vortex of identical geometric identity, and phase is separately installed with working gear
Position difference 180 degree and the equal crank axle of eccentricity, are connected by rolling bearing with the work nest on slider waveguide rod, by work tooth
The convert rotational motion of wheel is the straight reciprocating motion of upper and lower slider waveguide rod, and two crank axles cause the instantaneous of top shoe guide rod
Forward travel distance and speed are equal with instantaneous the setback distance and speed of sliding block guide rod, make to be fixed on sliding block and lead
For carborundum line on bar when moving in circles cutting workpiece, active length remains constant, mounted in upper and lower slider waveguide rod end
Carborundum line be achieved that reciprocating cutting to non-metal workpiece, and heap silk and diamond dust will not be formed in the incision of workpiece
Line tension is excessive, or even fracture of wire phenomenon.There is take-up and pay-off device on slider waveguide rod at the same time, for fixing carborundum line, replacing Buddha's warrior attendant
Sand line and the active section for changing carborundum line, floating material pressing device and fixed material-supporting device push down nonmetal plate, are cut with reducing
The vibration of nonmetal plate during cutting, being cut feeding, blanking and the feed motion of plate can be completed by manual operation.Below
Form according to complete machine, be illustrated one by one.
1st, gear drive is described in Fig. 1, Fig. 2 and Fig. 3, and motor 2 is driven by shaft coupling 3 and bearing block 4
Driving gear 11, working gear 12 and lower working gear 13 rotate in same direction in drive, driving gear 11 and working gear 12 and 13
All it is fixed on lathe bed 1, two working gears 12 and 13 on the basis of crossing the horizontal plane of driving gear axle center line to be arranged symmetrically peace
Dress.
2nd, crank block guide-bar mechanism is described in Fig. 1, Fig. 3 and Fig. 4, is located at working gear 12 and lower work tooth
Crank axle 15 on wheel 13 is by the work nest on rolling bearing 21 and slider waveguide rod 14, by the convert rotational motion of working gear
For the straight reciprocating motion of slider waveguide rod；Due to respectively having on the identical working gear 12 and 13 of two consistent physical dimensions of steering
The identical position phase difference of a piece eccentricity is the crank axle of 180 degree, and the work nest of upper and lower slider waveguide rod passes through rolling bearing 21
It is separately mounted on two crank axles so that instantaneous the forward travel distance and speed of top shoe guide rod are instantaneous with sliding block guide rod
Setback distance and speed are equal, and when carborundum line moves in circles cutting workpiece, active length remains constant.Sliding block
One end of guide rod 14 is connected by dovetail guide groove with lathe bed 1, and the other end of slider waveguide rod by work nest and is installed on crank axle
On rolling bearing 21 connect, the joint gap between the work nest and rolling bearing is eliminated in use, to eliminate the sliding block
Joint gap (can be realized by reconditioning gap adjusting pad 35) between guide rod and dovetail guide groove so that slider waveguide rod changes
During the direction of motion, carborundum line does not produce vibration or counter motion gap.
When crank axle is rotated with working gear, its angular speed rotated is ω, bias of the crank axle on working gear
Distance is r, then in t moment, the distance that sliding block guide rod advances is s1=r+rcos ω t；Within the t times, top shoe guide rod
The distance of advance is s2=r+rcos (180+ ω t), then the distance and be constant 2r that slider waveguide rod advances at any time up and down,
The distance and speed that i.e. top shoe guide rod advances are exactly equal to the distance and speed of sliding block guide rod retrogressing, ensure that cutting process
The length of middle carborundum line is constant, that is to say, that carborundum line will not be elongated or shorten when working, and will not be formed in incision
Heap silk, sand line tension be excessive and fracture of wire, and impulse stroke during whole carborundum line cutting is 2r, when motor speed and gearratio
After determining, the eccentric distance of the cutting speed of manual carborundum line cutting machine to crank axle on working gear is directly proportional.
