Currently, collapse for above-mentioned inner ring of steel coil and roll up situation, what is generallyd use is that the mode of artificial spot welding carries out, human weld
Be primarily present two problems: first is that production efficiency is low, labor intensity of workers is big；Second is that the solder joint of human weld may in rear process
Can be by drawing crack, the solder joint of drawing crack falls the surface defect that will affect steel band on steel band.
Summary of the invention
The purpose of the utility model is to provide a kind of cold rolling hards to roll up core welder, it can solve current human weld
The problem of production efficiency is low and influences steel strip surface quality.
To solve the above-mentioned problems, the technical solution adopted in the utility model is:
This cold rolling hard rolls up core welder, including bottom plate, and the bottom plate is equipped with transverse-moving mechanism, the transverse-moving mechanism
It is connected with elevating mechanism, the elevating mechanism includes the driving that horizontally disposed lifting arm and the driving lifting arm move up and down
The free end of component, the lifting arm is provided with front support and rear support；Weldering is equipped between the front support and the rear support
Socket part.
In above technical scheme, further scheme may is that the transverse-moving mechanism includes the traversing branch being vertically arranged
Frame and the horizontal translational components for being located at the traversing bracket lower part, the horizontal translational components include the tooth being located on the bottom plate
Item and with the rack gear meshed gears, the gear driven by the first motor that is located on the traversing bracket；The cross
It moves bracket and is equipped with the longitudinal groove moved up and down for the lifting arm.
It is further: the driving part of the elevating mechanism include the screw rod being located on the transverse-moving mechanism and with the silk
The feed screw nut of bar cooperation, the feed screw nut are fixedly connected with the lifting arm；The screw rod is by being arranged in the traversing branch
Second motor driven of top of the trellis.
Further: the lifting arm is the cuboid cantilever beam that cross section is square, one end and the traversing branch
Frame is flexibly connected.
It is further: the front support and the rear support it is equal there are four, each side of the lifting arm is set；Institute
Front support and the rear support is stated to be driven by the cylinder being arranged in the lifting arm.
Further: the weld part includes electrode tip holder and electrode, the weld part altogether there are four, be separately positioned on described
Each side of lifting arm, the electrode tip holder are driven by the cylinder.
By adopting the above-described technical solution, the utility model has the following beneficial effects: compared with prior art
1, the use of the utility model inner ring mash welder, inner ring of steel coil are taken the lead fixed realization Automation of Welding, are replaced completely
Human weld's operation；Greatly improve the working efficiency of spot welding；
2, chill volume eliminates human weld's solder joint and is drawn in subsequent handling after the utility model carries out welding core
It splits, welding slag falls the case where influencing cold-rolled quality, improves the quality of cold-rolled products, is the next step --- smooth full whipping
Rolling creates condition；Cold rolling coil lumber recovery improves 0.2%, and by 4000 yuan/ton of cold-rolled steel coils price, the annual production of company is cold
About 2,500,000 tons of volume is rolled, can create within 1 year benefit: 250 × 0.2% × 4000=20,000,000 yuan.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the A direction view of Fig. 1.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples:
This cold rolling hard as shown in Figure 1 and 2 rolls up core welder, including bottom plate 13, and bottom plate 13 is equipped with cross sliding machine
Structure, transverse-moving mechanism are connected with elevating mechanism, and elevating mechanism includes that horizontally disposed lifting arm 2 and driving lifting arm 2 move up and down
Driving part, driving part include the screw rod 7 being located on transverse-moving mechanism and with screw rod 7 cooperate feed screw nut 8；Screw rod 7 by
Second motor driven 11 at traversing 1 top of bracket is set；Lifting arm 2 is the cuboid cantilever beam that cross section is square,
One end is flexibly connected with the screw rod 7 in traversing bracket 1 by feed screw nut 8；The free end of lifting arm 2 is provided with 6 He of front support
Rear support 3；Front support 6 and rear support 3 there are four, each side of lifting arm 2 is set；Front support 6 and rear support 3 by
Cylinder (not shown) driving in lifting arm 2 is set；Weld part is equipped between front support 6 and rear support 3, weld part includes electricity
Electrode seat 5 and electrode 4, wherein electrode tip holder 5 is driven by the cylinder being arranged in lifting arm 2；There are four weld part is total, it is separately positioned on
Each side of lifting arm 2；Transverse-moving mechanism includes the traversing bracket 1 being vertically arranged and is located at moving horizontally for traversing 1 lower part of bracket
Component, horizontal translational components include set rack gear 12 on base 13 and with 12 meshed gears 10 of rack gear, gear 10 is by setting
First motor 9 on traversing bracket 1 drives；Traversing bracket 1 is equipped with the longitudinal groove moved up and down for lifting arm 2.
The present embodiment course of work: being detected by infrared ray range sensor, and elevating mechanism is driven by the second motor 11
Screw rod 7, feed screw nut 8 rise to coil of strip center, and transverse-moving mechanism is acted traversing by lifting arm 2 by gear 10, rack gear 12
It is sent to the distance of coil of strip inner setting, front support 6, rear support 3 open stretching steel band by cylinder, and electrode tip holder 5 passes through cylinder
Stretching allows electrode 4 to touch steel band, is welded after energization, and after the completion of welding, electrode tip holder 5 is retracted, and front support 6 retracts, rear to prop up
Support 3 retracts, and transverse-moving mechanism backs to origin, and elevating mechanism drops to origin, and welding is completed, and circulation starts next time for waiting；Cause
Inner ring of steel coil is taken the lead position and is not fixed, and when the position of spot welding is from taking the lead far, takes the lead that sagging the volume that collapses can be formed, to solve to collapse, volume is asked
Topic, mash welder are fitted with one group of electrode 4 and electrode tip holder 5 in four direction up and down, are successively welded along inner ring direction,
Which after four direction welding, no matter take the lead to take the lead to be no more than the 1/4 of inner ring of steel coil with a distance from solder joint, at this time in direction
Steel coil strip head sagging will not form the volume that collapses, because of multi-point welding, core firm welding is reliable, will not loosen, and avoids internal layer coil of strip
Sliding causes the abrasive quality problems of belt steel surface.
