Abstract
The utility model discloses a pressure-maintaining tumor pushing device in a steel-rail flash welding machine. The device comprises a tumor pushing knife, tow tumor pushing cylinders and a tumor pushing knife holder, wherein the two tumor pushing cylinders are respectively fixed on a left box body and a right box body; the tumor pushing knife holder is connected with the front ends of the piston rods of the two tumor pushing cylinders; when in tumor pushing, the back surface of the tumor pushing knife pushes against the front surface of the tumor pushing knife holder. In the tumor pushing process, the stress of the tumor pushing knife is uniform, and the precision of the tumor pushing knife is high, thereby eliminating the affection on the welding seam caused by the stretching stress in asteel rail and reducing the abrasion to a jaw.
Description
Technical field
The utility model relates to a kind of steel rail flash welding machine, and especially the pressurize in the steel rail flash welding machine pushes away the knurl structure.
Background technology
The seamless process of rail track has been eliminated the seam of rail, has also eliminated the impact and the vibrations of wheel and joint gap in the train driving, has prolonged the service life of wheel track parts, has reduced maintenance cost.In the domestic existing rail welding machine, the general knurl device that pushes away of routine that adopts pushes away knurl at present.The conventional knurl device that pushes away is formed by pushing away celectome, knife rest and two pairs of worm gears, worm screws, push away celectome by knife rest and two worm screws be directly installed on rail welding machine about on two casings.When pushing away knurl, two casings that the upset oil cylinder is installed unclamp rail by clamping cylinder, and upset oil cylinder withdrawal then drives and pushes away the knurl that pushes away that butt welded seam is finished in the celectome motion.The conventional knurl mode that pushes away has following shortcoming: one, need manual adjustment knife rest and worm gear to push away the quality of knurl to guarantee weld seam, push away the knurl unbalance stress, precision is low; Two, can not satisfy the needs of 500 meters of welding or longer long rail or locking weldering (, and just beginning to weld after in rail, producing certain tensile stress) with rail certain length that stretches; Three, the jaw serious wear of rail welding machine.
Summary of the invention
The purpose of this utility model is to provide that a kind of to push away celectome stressed evenly, can eliminate the pressurize that exerts an influence owing to rail in-draw stress butt welded seam and push away the knurl device.
In order to achieve the above object, the technical solution of the utility model is: a kind of pressurize pushes away the knurl device, comprise and push away celectome, also having two pushes away knurl oil cylinder and one and pushes away the celectome tool rest, two push away the knurl oil cylinder and are separately fixed on the left and right casing, push away celectome tool rest and two piston rod front end loads that push away the knurl oil cylinder, when pushing away knurl, push away the celectome back side and be resisted against the front that pushes away the celectome tool rest.
As further improvement of the utility model, the described celectome tool rest that pushes away comprises left tool rest, right tool rest and top tool rest, and wherein left tool rest is connected with the top tool rest by pin respectively with right tool rest.
Described left tool rest, right tool rest are fixed on two piston rod front ends that push away the knurl oil cylinder by attachment screw respectively, and lock by holding screw.
Described two push away the knurl oil cylinder and are fixed on the left and right casing by nut respectively.
In order to guarantee that two push away knurl oil cylinder synchronization action, described two oil circuits that push away the knurl oil cylinder are connected to flow divider-combiner jointly.
In order in pushing away the knurl process, not hurt rail itself, to reduce artificial polishing amount and increase the service life, the described celectome that pushes away comprises continuous left side cutter hub, top cutter hub, right side cutter hub and bottom cutter hub, the cutter hub that wherein is positioned at head end and tail end is provided with retaining mechanism, and described cutter hub is provided with cutting edge; In the time of in working order, described retaining mechanism makes the cutter hub that is positioned at head end and tail end interconnect locking, make the cross sectional shape of the cutting edge formation rail of described cutter hub, in left side cutter hub, top cutter hub, right side cutter hub and bottom cutter hub, be equipped with installing hole, resilient supporting unit be housed in installing hole and the keeper that part is stretched out the cutting edge of above-mentioned cutter hub is housed.
After adopting said structure, because also having two pushes away knurl oil cylinder and one and pushes away the celectome tool rest, two push away the knurl oil cylinder and are separately fixed on the left and right casing, push away celectome tool rest and two piston rod front end loads that push away the knurl oil cylinder, therefore can make that to push away celectome in pushing away the knurl process stressed evenly, the precision height also makes to push away knurl and be more prone to, and does not need manual adjustment knife rest and worm gear; Because when adopting the utility model to push away knurl, but welding machine still butt welded seam both sides rail keep clamped condition, therefore can eliminate because the influence of rail in-draw stress butt welded seam, satisfy 500 meters of welding or longer long rail or lock the needs that weld; Because clamping is firm when adopting the utility model to push away knurl, make rail and jaw be difficult for relatively moving, therefore can reduce wearing and tearing to jaw.
