Abstract
The invention relates to metal forming processes, in particular to a welding pin forming process for a waste heat recovery boiler. The process comprises the following steps that firstly, a curve extension and take-up machine is used for carrying out curve extension diameter reducing and take-up on a phi6.5 rolled wire produced in a steel mill, the outer diameter of the wire is gradually reduced to be within the range of 5.0-6.4 mm, scale can be removed while extension diameter reducing is carried out, and the wire leaves a curve extension machine after being taken up; secondly, the wire obtained after curve extension and take-up is fed into a pin cutting machine through a conveying device, the pin cutting machine continuously carries out pin cutting on the wire, and batched semi-finished welding pins the same in length are obtained; and thirdly, the semi-finished welding pins obtained in the second step are fed into a dedicated shot blasting machine through the conveying device for shot blasting rust removal. Due to the above technical scheme, the welding pin forming process has the beneficial effects that the curve extension and take-up machine is used for carrying out scale removing, extension diameter reducing and straightening machining at the same time, and a traditional process of carrying out cold drawing and heat treatment annealing after acid pickling is replaced.
Description
Technical field
The present invention relates to metal forming technology, more particularly to a kind of heat recovery boiler capillary forming technology.
Background technology
Needle-tube capillary is a kind of hardware commonly used on the devices such as heat recovery boiler hot channel peculiar to vessel,
In the heat recovery and radiation processes of boiler, using capillary thermal cycle can be accelerated, improve heat energy utilization and the efficiency that sheds.It is actual
Using when capillary one end need to be welded on boiler tubing surface, as a kind of a large amount of structural members for using, its production technology
Stability and high efficiency becomes particularly important.The production technology of generally this capillary is complex, and original production process is by steel mill's productionExternal diameter, through pickling scale removal, is then reduced to required external diameter, cold-drawn by wire rod as masterbatch through cold-drawn twice
Afterwards, carry out cutting pin processing, cut and carry out after the completion of pin heat-treatment of annealing, followed by the rust cleaning of drum-type bur removing device for card clothing optical crosstalk, finally obtain
To product.Conventional hot candied acc power is 18.5kw, and Cold Drawing Process needs two drawing machines, adds annealing process, and power consumption is big.
The process is usedWire rod is used as masterbatch, and process procedure is various, and artificial running cost is high, the time-consuming consumption of heat-treatment of annealing process
Can, acid cleaning process can be polluted, and also easily produce noise and dust pollution, and the production time is long, and efficiency is low.It is badly in need of one now
Plant the simple efficient capillary shaping production technology of economic and environment-friendly and technical process.
The content of the invention
The technical problem to be solved in the present invention is how to overcome the deficiencies in the prior art, there is provided a kind of heat recovery boiler is used
Capillary forming technology.
The technical scheme that adopts for achieving the above object of the present invention is：A kind of heat recovery boiler capillary forming technology,
The technique is comprised the following steps, the first step, extends what admission machine produced steel mill using curveWeb-like wire rod carries out curve
Extend tube reducing and take-up, the external diameter of wire rod is gradually decreased in the range of 6.4-5.0mm, while extending tube reducing oxidation is can remove
Skin, wire rod leaves curve Jing after take-up and extends admission machine；
Second step, conveyer curve is extended the wire rod feeding after take-up and is cut in pin machine, cuts pin machine and continuously wire rod is entered
Row cuts pin, obtains in batch and length identical capillary semi-finished product；
3rd step, conveyer will carry out ball blast and removes in the capillary semi-finished product obtained by step 2 feeding Shot-blasting Machine
Rust, rust cleaning completes that high-quality needle-tube capillary can be directly obtained.
Used as preferential technical scheme, it is including multiple continuous arrangements and upper and lower that the curve used in the first step extends admission machine
Cylinder roller staggeredly, each roller can have damping rotary, extend process continuously and wire rod elongation is uniform.
Used as preferential technical scheme, the curve extends the roller spacing of admission machine and becomes larger from the front to the back, makes song
The extensional amount that line extends process is less and less, obtains required diameter.
Used as preferential technical scheme, the Shot-blasting Machine is the closed capillary shot-blasting machine of automation.
Used as preferential technical scheme, the Shot-blasting Machine can automatically pass in and out capillary, and the Shot-blasting Machine is provided with and subtracts
Make an uproar and dust exhaust apparatus.
Used as preferential technical scheme, whole forming technology conveyer streamline is that semi-circular distribution is alternatively linear
Distribution.
As a result of above-mentioned technical proposal, the advantage of capillary forming technology of the present invention is to be extended using curve
Admission machine carries out oxide skin removal, extends tube reducing and alignment working process simultaneously, instead of after traditional pickling cold-drawn and Re Chu again
Reason annealing process, greatly shortens technological process, and effectively save electric energy reduces production cost；Mitigated using Shot-blasting Machine
Noise and dust pollution, improve the working environment of operating personnel, and labour intensity is reduced, technical process compact in design, effectively
Place is saved on ground, and new technology significantly improves production efficiency, and automaticity is strengthened, and is saved manually, with significant beneficial
Effect.
