Abstract
A welding technology for the mixing-stirring blade of mixing-kneading machine includes such steps as lofting, making fixture, gas cutting, beveling both edges at root position, build-up welding of stirring blade on mainshaft, and build-up welding of a hard alloy (667) layer with 5-6 mm in thickness.
Description
Technical field
The present invention relates to the capital equipment-kneading machine in the carbon product production, especially relate to the welding procedure of motor driven rimer for kneading machine.
Background technology
Kneading machine is the capital equipment that carbon product is produced, and the height of its normal operation rate directly influences the output of anode mix.Motor driven rimer for kneading machine wearing and tearing at present are the subject matter that occurs during kneading machine uses.Thereby motor driven rimer for kneading machine wearing and tearing make that the kneading machine running rate is low has reduced moving life cycle of stirring cutter, thereby has increased maintenance cost, prolonged maintenance time, has increased cost.The major influence factors of motor driven rimer for kneading machine wearing and tearing is that the built-up welding mode is improper, secondly is accurately to locate.Also there is not a kind of method to address the above problem at present.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the welding procedure of the motor driven rimer for kneading machine that provides a kind of and can make the kneading machine running rate improve, prolong moving life cycle of stirring cutter, reduce maintenance cost, shorten maintenance time, reduce cost.
The present invention realizes in the following way:
A kind of welding procedure of motor driven rimer for kneading machine, it is characterized in that: it comprises following technical process successively: setting-out, make jig, draw with the side expanded view on steel plate and move the shape of stirring cutter, under the gas welding, root both sides bevel, with the dc reverse connection method will move at normal temperatures stir the cutter built-up welding on the main shaft of kneading machine, wait to weld after, get final product with heap 667 welding rod built-up welding 5-6mm thick hard alloy layer more above;
The welding rod of described built-up welding is heap 667, earlier the welding rod preheating more than 2 hours, will be moved at normal temperatures with the dc reverse connection method then and is stirred the cutter built-up welding on the main shaft on the kneading machine before the built-up welding, and does not weld at the groove place.
The present invention has following effect:
1) method provided by the invention broken motor driven rimer for kneading machine can not this routine of cold welding, initiated motor driven rimer for kneading machine built-up welding new technology at home.
2) adopt the moving cutter technology of stirring of method making provided by the invention simple, convenient, the moving cutter standard of producing of stirring adheres to specification, and uses reliably, and the life-span is long, has improved the production capacity of kneading machine greatly, enables to guarantee the needs of ordinary production.
3) method provided by the invention has been avoided high-temperature operation in the past, thereby has been improved working environment in built-up welding at normal temperatures, has reduced labour intensity greatly.
4) reduced cost: adopt more than 30,000 yuan of the annual fuel savings expense of method provided by the invention, about 50,000 yuan of maintenance cost.
5) improved the running rate of kneading machine: as can be seen: movingly stir the cutter welding procedure by improving, improved the running rate (before improving, having improved 14.2%) of kneading machine, reached the set goal from following table.
9-12 month kneading machine running rate statistical form
| Month | Scheduled production (T) | Plan the duration of runs (h) | The real-world operation time (h) | Running rate (%) |

The specific embodiment
A kind of welding procedure of motor driven rimer for kneading machine, it is characterized in that: it comprises following technical process successively: setting-out, make jig, on steel plate with the side expanded view moving shape of stirring cutter of drawing, under the gas welding, root both sides bevel, to move at normal temperatures with the dc reverse connection method and to stir the cutter built-up welding on the main shaft of kneading machine, after waiting to weld, get final product with the thick hard alloy layer of heap 667 welding rod built-up welding 5-6mm more above, setting-out is the moving side expanded view of stirring cutter of drawing Φ 380 to Φ 220 in 1: 1 ratio with paper, make jig and move the expanded views of stirring cutter Φ 380 continuously on the thick steel plate of 1.5mm, drawing three by 1: 1 ratio, expanded view is cut, spool by Φ 380 faces, top electrode holder hand, the groove that open on the root both sides is 8*45 °, the welding rod of built-up welding is heap 667, before the built-up welding earlier with the welding rod preheating more than 2 hours, use built-up welding under the dc reverse connection method normal temperature then, does not weld at the groove place.
Claims (2)
1. the welding procedure of a motor driven rimer for kneading machine, it is characterized in that: it comprises following technical process successively: setting-out, make jig, draw with the side expanded view on steel plate and move the shape of stirring cutter, under the gas welding, root both sides bevel, with the dc reverse connection method will move at normal temperatures stir the cutter built-up welding on the main shaft of kneading machine, wait to weld after, get final product with heap 667 welding rod built-up welding 5-6mm thick hard alloy layer more above.
2. the welding procedure of motor driven rimer for kneading machine as claimed in claim 1, it is characterized in that: the welding rod of described built-up welding is heap 667, earlier the welding rod preheating more than 2 hours, will be moved at normal temperatures with the dc reverse connection method then and stirred the cutter built-up welding on the main shaft on the kneading machine before the built-up welding, does not weld at the groove place.
