Description

Roll bending bonding machine

Technical field

The invention belongs to linearly crooked metal sheet, particularly relate to a kind of roll bending bonding machine.

Background technology

Veneer reeling machine carries out the bending moulding lathe of continuity point to sheet material, has the function of the difformity sheet materials such as the O type that rolls, U-shaped, multistage R.The field difference of veneer reeling machine owing to using, kind is also different.Three rolls plate bending machine and four-roll plate bending machine is divided into from roller number.The most conventional is three rolls plate bending machine, and it mainly comprises top roll, lower roll and limit roller, and top roll is main drive roller, is connected with power source, and lower roll vertical displacement movement to clamp sheet material, and is engaged with upper roll gear by lower roll gear; Limit roller does to incline elevating movement, has pre-bending and volume circle dual-use function.Compact conformation, operating maintenance is convenient.

Existing most of pipeline is all first adopt veneer reeling machine to be rolled into roll bending, then by roll bending from after veneer reeling machine takes off, then be fixed on weld jig and carry out clamping welding.Whole process need take off roll bending, troublesome poeration back and forth.

Therefore, be badly in need of a kind of device that can weld roll bending on veneer reeling machine, to reduce, roll bending taken off and then fixing operation.

Summary of the invention

Object of the present invention is providing a kind of roll bending bonding machine, is taken off and then fixing operation by roll bending to reduce.

In order to achieve the above object, base case of the present invention is: roll bending bonding machine, comprise frame, top roll, lower roll, limit roller and the power source for driving top roll to rotate, described top roll, lower roll and limit roller are all rotatably connected in frame, also comprise grip unit, welding gun, described welding gun is slidably arranged in frame, the clamping plate that described grip unit comprises electromagnet, attracts with electromagnet, described electromagnet and clamping plate are all curved, described electromagnet is fixed in frame, and described clamping plate are slidably arranged in frame.

The principle of this base case is: be first placed between top roll and lower roll by steel plate, starts power source, then veneer reeling machine work.Steel plate is spooled after becoming roll bending, stop power source, meanwhile, connect the power supply of electromagnet.Now, electromagnet produces magnetic force, attracting with clamping plate, thus is clamped by roll bending.In addition, another part of roll bending between top roll and lower roll, is then clamped by top roll, lower roll.Afterwards, start welding gun, and promote welding gun and move, then can carry out welding operation to roll bending.

The beneficial effect of this base case is: this programme produces magnetic force by electromagnet and clamping plate attract each other, thus is fixed by roll bending, its fast response time.And after welding completes, by electromagnet power-off, can easily roll bending be taken off, easy to operate.Electromagnet and clamping plate are all curved, and large with the contact surface of roll bending, then frictional force is large, and fixed effect is better.Compared with traditional veneer reeling machine, this programme is without the need to taking off roll bending, and roll bending can be fixed after connecting the power supply of electromagnet, simple to operate, operating efficiency is high.

Scheme two: based on this, scheme is preferred, and described frame is provided with dovetail groove, and welding gun is provided with the slide block matched with dovetail groove, and described slide block is fixed on welding gun.Welding gun is slidably connected in frame by the mode of dovetail groove, and its advantage is: one is that precision is higher and gap is adjustable, and two is that bearing capacity is large.

Scheme three: this is the preferred of scheme two, clamping plate and electromagnet all surface are provided with rubber layer.Rubber layer has good cushioning effect, can effectively avoid clamping plate or electromagnet to be crushed by roll bending.Meanwhile, rubber layer also has good insulating effect, avoids electromagnet to leak electricity.

Scheme four: this is the preferred of scheme three, described clamping plate are iron plate.Relative to the material that other can react with electromagnet, such as nickel, cobalt etc., the cost of iron plate is low, can effectively reduce the production cost of enterprise.

Scheme five: this is the preferred of scheme four, described clamping plate all surface is provided with antirust coat.Antirust coat can effectively by iron plate and air exclusion, avoid oxidized the getting rusty of iron plate and cannot with the problem of attraction.

Scheme six: based on this, scheme any one of scheme to scheme five is preferred, and described power source is servomotor.Relative to common motor, the controllability of servomotor is stronger, long service life.

Detailed description of the invention

Below by detailed description of the invention, the present invention is further detailed explanation:

Reference numeral in Figure of description comprises: top roll 10, lower roll 20, limit roller 30, electromagnet 41, clamping plate 42, welding gun 50, frame 60, roll bending 70.

As shown in Figure 1 and Figure 2, roll bending bonding machine, comprises frame 60, top roll 10, lower roll 20, limit roller 30 and the power source for driving top roll 10 to rotate.This power source is servomotor, and for common motor, the controllability of servomotor is stronger, long service life.Top roll 10, lower roll 20 and limit roller 30 are all rotatably connected in frame 60.In addition, grip unit, welding gun 50 is also comprised.Frame 60 is provided with dovetail groove, and welding gun 50 is provided with the slide block matched with dovetail groove, and slide block is welded on welding gun 50.The clamping plate 42 that grip unit comprises electromagnet 41, attracts with electromagnet 41.Electromagnet 41 and clamping plate 42 all curved, electromagnet 41 is arranged in frame 60, and clamping plate 42 are slidably arranged in frame 60.These clamping plate 42 are iron plate, and the outer surface of iron plate is coated with one deck antirust paint.Antirust paint can effectively by iron plate and air exclusion, avoid oxidized the getting rusty of iron plate and cannot with the problem of attraction.Clamping plate 42 and electromagnet 41 all surface are provided with rubber layer.Rubber layer has good cushioning effect, can effectively avoid clamping plate 42 or electromagnet 41 to be crushed by roll bending 70.Meanwhile, rubber layer also has good insulating effect, avoids electromagnet 41 to leak electricity.

In addition, in this programme, it is excessive that the distance between electromagnet 41 and roll bending 70 should not be arranged, and after avoiding electromagnet 41 to be energized, clamping plate 42 are subject to larger power and roll bending 70 is pushed up distortion.Under normal circumstances, the distance between electromagnet 41 and roll bending 70 is less than 0.5cm, and electromagnet 41 now also has certain position-limiting action to roll bending 70, avoids roll bending 70 excessive deformation.

During concrete operations, first steel plate is placed between top roll 10 and lower roll 20, starts power source, the then work of roll bending 70 machine.Steel plate is spooled after becoming roll bending 70, stop power source, meanwhile, connect the power supply of electromagnet 41.Now, electromagnet 41 produces magnetic force, attracting with clamping plate 42, thus is clamped by roll bending 70.In addition, another part of roll bending 70 between top roll 10 and lower roll 20, is then clamped by top roll 10, lower roll 20.Afterwards, start welding gun 50, and promote welding gun 50 and move, then can carry out welding operation to roll bending 70.

Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
