Abstract
The invention relates to a filament cutting-off device which is used for reducing residues of filaments during cutting off. In the device, a sliding table base is connected with a knife rest in a set work angle. A first sliding table is connected with the sliding table base in a linear movement mode and is provided with a first blade, and a second sliding table is connected with the sliding table base in a linear movement mode and is provided with a second blade. A first driving mechanism is connected with the first sliding table, and a second driving mechanism is connected with the second sliding table. When the first driving mechanism and the second driving mechanism are extended out, the first driving mechanism and the second driving mechanism respectively drive the first sliding table and the second sliding table to go forward to a filament cutting position, and the filaments are cut off by the first blade and the second blade, wherein the angles of the first blade and the second blade for cutting off the filaments are relative to the work angle of the sliding table base. When the first driving mechanism and the second driving mechanism are shrunk, the first driving mechanism and the second driving mechanism respectively drive the first sliding table and the second sliding table to go back to a starting position.

Carriage saddle 201 followed in knife rest 401 first line of a couplet, carriage saddle 201 is connected with knife rest 401, and can rotate an angle to set up suitable operating angle, then with respect to knife rest 401 around an axial line, for example fixed, to be fixed on this operating angle by two bolts 206.
Be fixed with two guideways on the carriage saddle 201, i.e. first guide rail 202 and first slide unit 203 thereof and second guide rail 207 and second slide unit 210 thereof.First guide rail 202 and second guide rail 207 are fixed on the carriage saddle 201 by the screw (not shown).First slide unit 203 is located on first guide rail 202 and can be moved along first guide rail, and second slide unit 210 is located on second guide rail 207 and can be moved along second guide rail.Fixing first blade 205 and second blade 208 respectively by screw 204 and 209 on first slide unit 203 and second slide unit 210.
Shown in Fig. 4-6, second driving mechanism comprises second cylinder 109, hinge 107 and two connecting rods 103,105.The tailpiece of the piston rod of second cylinder 109 is provided with hinge 107, and is hinged with an end of connecting rod 103,105 respectively by bearing pin 106, and the cylinder ear seat of second cylinder 109 is hinged with the second cylinder supports frame 108 on the carriage saddle by bearing pin 110.The other end of connecting rod 105 is hinged by the bearing pin 104 and second slide unit 210, and the other end of connecting rod 103 is hinged with second fixed pivot 101 on the carriage saddle 201 by bearing pin 102.
Similarly, first driving mechanism comprises first cylinder 309, hinge 307 and two connecting rods 303,305.The tailpiece of the piston rod of first cylinder 309 is provided with hinge 307, and is hinged with connecting rod 303,305 1 ends respectively by bearing pin 306, and the cylinder ear seat of first cylinder 309 is hinged with the first cylinder supports frame 308 on the carriage saddle by bearing pin 310; The other end of connecting rod 305 is hinged by the bearing pin 304 and first slide unit 203, and the other end of connecting rod 303 is then hinged with first fixed pivot 301 on the carriage saddle 201 by bearing pin 302.
In one embodiment, all be inlaid with joint axle bush 130 at each connecting rod 103,105,303,305 two ends and bearing pin hinged place, referring to shown in Figure 7.
The course of work of above-mentioned filament disconnecting device is described below.
During work, on knife rest 401, rotate carriage saddle 201, can adjust its operating angle by unclamping bolt 206 backs, and then adjust blade 205 on it and 208 chopping action movement direction, to obtain suitable cut-out angle beta, as shown in Figure 8, then that bolt 206 is fastening.It is relevant with the angle of carriage saddle 201 to cut off angle beta, is equal for example.
In service, the piston of second cylinder 109 stretches out or indentation, and the bearing pin 106 on the hinge 107 is followed piston rod and moved together, and the end that connecting rod 103,105 is connected with bearing pin 106 is followed bearing pin 106 motions, and rotates around bearing pin 106 separately.Because bearing pin 102 is fixed on the carriage saddle 201, thereby the other end of connecting rod 103 can only rotate and can not move around bearing pin 102; Bearing pin 104 is fixed on second slide unit 210, and can follow second slide unit 210 and move on carriage saddle 201, thereby the other end of connecting rod 105 can and can be followed second slide unit 210 and move together around bearing pin 104 rotations.When second cylinder, 109 pistons stretch out motion, hinge 107 drivening rods 103 counterclockwise (pressing Fig. 4 picture differentiates) rotate, drivening rod 105 clockwise directions rotate again, and the result of motion makes bearing pin 104 promote second slide unit 210 and moves (in the figure upward to) along second guide rail, 207 straight lines.
According to identical principle, the piston of first cylinder 309 stretches out when motion, and first slide unit 203 moves (downward direction in the figure) along first guide rail 202 to the second slide unit straight line.
When two cylinders stretch out simultaneously, the blade of fixing on two slide units 205 and 208 will run to the chopping position, and filament 20 (as tungsten filament) is cut off in its chopping action; Owing to two blades 205 and 208 move with all disconnected angle beta directions, blade 208, cutter position will more be pressed close to the root that filament extends under it, and this will make the filament residual quantity after cutting off greatly reduce, and reference is shown in Figure 9.
After chopping was finished, the retraction piston of two cylinders drove two slide units 203 and 210 and leaves and get back to initial position, waits for the next chopping cycle.As can be seen, do not use in the whole cutting-off process, therefore avoided bump vibration and noise such as the so traditional position-limit mechanism of positive stop.
In sum, the described filament disconnecting device of the above embodiment of the present invention, owing to used new filament cutting mechanism, have the following advantages when realizing the chopping function: (1) can reduce remaining filament length largely; Do not have the mechanical position limitation structure when (2) chopping finishes, avoided consequent bump vibration and noise; (3) cylinder has increased the strength of chopping by linkage, can adapt to the tungsten filament that cuts off larger diameter.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
