For convenience of description, the end that the scissors roller is installed of shear arm is head, and an end of the installation gear of rotating shaft is rear portion,

Refer to Fig. 1,

A kind of flux-cored wire segment cutter, comprise base and be positioned at two framed side wallboards on base---the first framed side wallboard 1 and the second framed side wallboard 4, two described framed side wallboards are parallel to each other, middle part by two bearing pins 6 and two groups of shear arms 2 between two framed side wallboards is articulated and connected, during the operation of flux-cored wire segment cutter, the afterbody of two groups of shear arms is fixedly connected with by connecting rod 24, the head of every group of shear arm all is connected with rotating shaft 16 by rolling bearing 13, the middle part of rotating shaft is fixedly connected with scissors roller 12, on each scissors roller, scissors base 10 is installed removably, a scissors bit 11 is installed on each scissors base removably, after installing, each scissors bit is pressed on scissors base by pressing plate 9, the end of each scissors bit is provided with the blade 1101 of intersection,

The rear end of two rotating shafts also key is connected with the 3rd gear and the 4th gear, also in the mode that can rotate in a circumferential direction, be connected with the first gear 7 and the second gear 14 on bearing pin, be exactly that the first gear and the second gear pass through the rolling bearing empty set on bearing pin 6 particularly, the first gear and the second gear rotate and bearing pin does not rotate, the first gear and the engagement of the 3rd gear, the second gear and the 4th gear 17 engagements, the first gear and the engagement of the second gear, the first gear or the second gear are connected with drive unit, the end face that in the present embodiment, is wherein the second gear is provided with the tooth meshed with clutch 19, by clutch, with motor 20, be connected.

Between blade, folded acute angle is 60 °, and the angular bisector of this acute angle is positioned on the opposite direction of the direction of welding wire operation or welding wire traffic direction.Be provided with welding wire mouth-sealed portion 1102 and welding wire introducing portion 1103 in 60 ° of angular range that scissors bit forms at two blades, welding wire mouth-sealed portion and welding wire introducing portion have distribution in two 60 ° of angles of vertical angles each other, wherein comparatively close is the welding wire mouth-sealed portion, and slightly far point is the welding wire introducing portion.

The rear end of every group of described shear arm all is installed with eccentric shaft 25, the eccentric shaft of every group of shear arm is also through connecting rod, it is concentric that eccentric shaft is through the Nei position, hole of two shear arms of every group, eccentric shaft is through the position and the position bias of passing shear arm of connecting rod, and the rear portion of shear arm or connecting rod is provided with for fixed eccentric shaft, prevents the holding screw 15 that eccentric shaft rotates.

Also be provided with guide support beam 26 between left side plate, the middle part of guide support beam is provided with guide pipe 27, and guide pipe is in order to be directed to clipped position by welding wire.

The operating principle of this patent is:

When adjusting scissors base on the scissors roller and the relative position between scissors bit, after the cross one another blade of two scissors bits can be alignd, clutch 19 is closed.When welding wire moves, motor 20 drives the second gear 14 motions, second gear driven the first gear 7 rotations, the 3rd gear rotation of the first gear driven, the 4th gear 17 rotations of the second gear driven, because the gearratio between these three pairs of gear drives is 1, and the 4th gear, the 3rd gear can drive the scissors rollers by rotating shaft 16 respectively and rotate with rotating speed.Every through one section distance that needs cutting, upper and lower blade 1101 all revolves and turns around, by welding wire introducing portion 1103 by operating welding wire correcting, make it to enter accurately the position that will cut off, and the end that the welding wire mouth-sealed portion 1102 of the top trip by scissors bit will not yet be cut off welding wire clamps, presss from both sides flat, sealing.And at upper scissors bit just down, the lower scissors head meets just upward the time, and the blade of two pairs of intersections is cut off welding wire, makes it to become welding rod.And the welding wire mouth-sealed portion by downstream clamps, presss from both sides flat, sealing by the afterbody of the welding wire cut off, guarantees that medicinal powder no longer spills.

When needs are sheared the welding rod of different length or diameter, can change scissors base and the scissors bit of different length, form the different radii of blade and the different size of blade.During replacing, the holding screw 15 on connecting rod or shear arm can be unclamped, make eccentric shaft 25 to rotate.Because the middle part of shear arm is hinged by bearing pin 16, by rotating upper and lower two eccentric shafts 25, can be so that the head of two shear arms, at a distance of different distance, arranges scissors base 10 and the scissors bit 11 of different length, in order to adapt to the different length of flux-cored electrode and the needs of diameter.

Although the above is described the preferred embodiment of this patent by reference to the accompanying drawings, but this patent is not limited to the above-mentioned specific embodiment, the above-mentioned specific embodiment is only schematic, be not restrictive, those of ordinary skill in the art, under the enlightenment of this patent, not breaking away from the scope situation that this patent aim and claim protect, can also make a lot of forms, for example: what 1. motor drove by clutch is not the second gear, but the first gear; 2. not necessarily the gearratio between each gear is 1, as long as the rotating speed of the 3rd gear of assurance driving-chain least significant end and the 4th gear is identical just passable.Within these all belong to the protection domain of this patent.
