A kind of strip scraping machine
Technical field
The invention belongs to metallic conduit production equipment field, particularly a kind of strip scraping machine.
Background technology
According to demand of technical standard, before welding, will shear neatly, and strip edges also will be cut into domatic by some metallic conduit, to ensure the welding quality of weld seam by dual-side for metallic conduit.In the past to the cutting of strip edges domatic, large multiplex cutter is sheared, and cutter is in shear history, strip edges portion will have certain ship clearance (10mm) to shear, and like this, just will inevitably cause raw-material waste, increase production cost, and cutter also must have special actuating unit, increase energy consumption.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of without the need to special actuating unit, save the energy, waste of raw materials can be avoided, reduce production cost, equipment is easy to assembly, cutter is fixed strip scraping machine.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of strip scraping machine, comprise base, positioner, press-roller device forms, it is characterized in that: also comprise a rotary head, positioner is slidably mounted on base, rotary head is installed in positioner leading flank, press-roller device is installed in inside positioner, described rotary head, by the first base, second base, first swaging clamp block, second swaging clamp block, cutter forms, first base is installed in positioner side, second base is installed on the first base, first swaging clamp block is installed on the second base, second swaging clamp block is installed on the first swaging clamp block, cutter is installed on the first swaging clamp block, between second swaging clamp block.
And described second base, on it, symmetry is shaped with arc angle modulation screw.
And it is all shaped with cutter draw-in groove for described first swaging clamp block, the second swaging clamp block, and two cutter draw-in grooves form square cutter hole clipping relatively.
And the described square cutter hole clipping cross section length of side is slightly less than the cutter cross section length of side.
And described cutter is a cross section is foursquare cuboid product, and its end is shaped with the edge of a knife.
And the described edge of a knife, its tapering is 56 to 63 degree.
Advantage of the present invention and beneficial effect are:
1. this strip scraping machine utilizes strip transmitting power, without the need to special power set, can save the energy;
2. this strip scraping machine directly scrapes ramp shaped at strip edges, can avoid waste of raw materials, reduce costs;
3. leave gap between this strip scraping machine swaging clamp block, cutter fixation can be made;
4. this strip scraping machine base is shaped with arc screw, convenient for assembly;
5. this strip scraping machine scientific structure design is reasonable, and having the saving energy, save raw material, reduce costs the advantages such as easy to assembly, cutter is firm, is a kind of strip scraping machine with higher innovation.

Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of strip scraping machine, comprise base 8, positioner, press-roller device 3 form, its innovation is: also comprise a rotary head 1; Positioner is slidably mounted on base, and rotary head is installed in positioner leading flank, and press-roller device is installed in inside positioner.
Rotary head, is made up of the first base 15, second base 14, first swaging clamp block 12, second swaging clamp block 11, cutter; Second base, on it, symmetry is shaped with arc angle modulation screw 16, for adjusting the relative position of the second base and the first base, thus the position of adjustment cutter and strip edges, to scrape desired angle; It is shaped with cutter draw-in groove 18 and 19 respectively for first swaging clamp block, the second swaging clamp block; Cutter is a cross section is the white steelwork of foursquare cuboid, and its end is shaped with the edge of a knife 20, and edge of a knife tapering is 56 to 63 degree, and empirical evidence, edge of a knife tapering is best about 60 degree scraping effects, and cutter is the longest for service time.First base is installed in positioner leading flank by welding, second base is installed on the first base by bolt 13, first swaging clamp block is installed on the second base by welding, second swaging clamp block is installed on the first swaging clamp block by hexagon socket head cap screw 17, cutter draw-in groove on first swaging clamp block, the second swaging clamp block forms square cutter hole clipping 10 relatively, the square cutter hole clipping cross section length of side is slightly less than the cutter cross section length of side, and cutter is installed in the square cutter hole clipping that formed between the first swaging clamp block, the second swaging clamp block; After cutter inserts square cutter hole clipping, because the square cutter hole clipping cross section length of side is slightly less than the cutter cross section length of side, between the first swaging clamp block, the second swaging clamp block, form a swaging clamp block gap 9, swaging clamp block gap is conducive to being securely fixed in by cutter in square cutter hole clipping.Two arc angle modulation screws on second base are convenient to eliminate rigging error, are conducive to the second base and the first base assembles.
Positioner is made up of coulisse 7, location leading screw 5, location leading screw watt seat 6, location screw 21, registration roller 2, location roller seat 4, a location leading screw watt seat is installed in base top surface outward flange, coulisse is installed in base top surface both ends and also and between base top surface forms chute, location roller seat is sliding to be loaded in chute, location screw is installed in the roller seat of location, and registration roller rotates vertical being loaded in the roller seat of location.
Coulisse is 2, is installed in edge before and after base top surface respectively.
Hold down gag is made up of roller devices 26, base plate 27, roller seat 25, pressure roller leading screw 23, pressure roller screw 24, leading screw seat 22, base plate is shaped with pressure roller slideway 28, and roller devices is 2 groups, for pushing down strip, makes strip keep smooth conveying.Base plate is installed in inside the roller seat of location, and leading screw seat is installed in plate top surface, and roller seat is slidably mounted on base plate medial surface, pressure roller leading screw upper end is rotated and is installed on leading screw seat, pressure roller leading screw lower end spinning pressure roller screw, pressure roller screw is fixedly mounted with mutually with roller seat, and roller devices rotates and is installed in roller seat.
Operation principle of the present invention is:
Two, this strip scraping machine (two platen band scraping machine structures are identical, and rotary head position is different) is installed in strip both sides on the slab band conveying device of format roll rear respectively relatively.First position when carrying out Welded tube production, make registration roller near strip edges, concrete grammar is: with spanner rotational positioning leading screw, namely location screw turns drives location screw to move on the leading screw of location, location screw moves and registration roller can be driven to move, and can reach the object of registration roller location like this; Then the relative position of the second base and the first base is adjusted by arc angle modulation screw, thus the relative position of adjustment cutter and strip edges, make cutter and strip edges be in optimum contacting state, to ensure the angle scraping requirement, obtain best scraping effect; Then adjust press-roller device, make roller devices close adhesion plate belt surface, smooth to keep strip to carry, ensure scraping effect; Like this, strip is in course of conveying, and namely its edge can be scraped desirable ramped shaped, to meet welding requirements.As required, also only monolateral scraping can be carried out.
