Description
Technical field
The present invention relates to a kind of manufacture method that is used for the compact flat vertical chain ring of drag conveyor more.
Background technology
Chain also is a consumable accessory as the main parts size of drag conveyor, and consumption is very big.Because China's girdle is distributed more widely, reserves are abundant, the geological conditions variation is various, coal seam thickness is generally 0.5～2.3m, and wherein the thinner seam of 1.2～2.3m occupies bigger proportion in the coalfield of China.Be subjected to the restriction in space to need project organization to satisfy the working face drag conveyor equipment of the high-yield and high-efficiency high reliability that 1.2～2.3m mining height thinner seam coal winning technology requires.
For adapting to the variation of drag conveyor, strengthen thereby need to design the mechanical performance of using the compact flat chain to make chain, and then increased the coal amount.
Traditional compact flat vertical chain ring is to forge ring, its manufacturing process following (is example with Φ 34 * 126 compact chains):
1, blanking rough forging; With heating furnace blank is heated to 1250 ℃; Behind forging molding on the die hammer, cut away burr with forcing press; The cooling back becomes the size of technological requirement with the abrasive machine reconditioning; Do normalized treatment with electric furnace then; So just finished the manufacturing of forging flat vertical chain ring;
2, the raw material with 9 meters of hot-finished material 23MnNiMoCr54 circular chain steel Φ 34mm length become the long charge bar of 395mm with Ya Li Ji G; Charge bar is sent into resistance heated machine clamping energising be heated to 680 ℃; The ready-made forging flat vertical chain ring of system is put into the heart tire of chain braider; The charge bar that heats is passed the forging flat vertical chain ring with the heart tire that manipulator inserts chain braider; Crooked chaining ring forming; Send into butt welding machine with manipulator then and finish welding sequence; Remove the welding burr; Be made into one and forge compact type chain of compiling weld-ring formation of flat ring.Compact type chain is heat-treated quenching, tempering, on stretching-machine, every five rings is applied certain pulling force by standard-required; Sampling is done various performance tests according to standard on reel chain then.After reaching standard-required, packing is put on market.The standard that this compact type chain is carried out is German DIN22255-2001, DIN22252-2001.
Compact vertical chain ring adopts to forge to encircle and has the following disadvantages:
When 1, forging the ring manufacturing, the high surface oxidation of raw material heating-up temperature, oxide is pressed into the chain ring surface and easily causes chain ring surface forging defect during die forging, influences mechanical performance;
2, the blank heating-up temperature is inconsistent before the forging, and the beginning forges final forging temperature and is difficult to control, causes the pitch size of chain link inconsistent, influences the comprehensive mechanical performance of chain;
3, forging the power consumption that encircles is more than three times of compacting ring;
4, the compacting ring adopts the hot rolling material straight forming, and the metallic fiber streamline circularizes, and mechanical performance and the result of use of comparing chain link with the forging ring are good;
5, forging ring is 1.5 times that compacting encircles with raw material, and be 4 times of compacting ring man-hour, the manufacturing cost height.
Summary of the invention
The purpose of this invention is to provide a kind of dependable performance, make the manufacture method of compact flat vertical chain ring easy, energy-conservation, with low cost.
The technical solution used in the present invention is:
A kind of manufacture method of compact flat vertical chain ring, its special feature is, comprise the following steps: Lian Tiao Gang G is become charge bar, charge bar is heated to 630-730 ℃ then, charge bar is sent into chaining movement tire, crooked chaining ring forming is sent charge bar into butt welding machine afterwards and is finished welding sequence again, put into immediately after the deburring on the mold of press bench, exert pressure and to finish in the chain link with heart tire insertion brake forming.
Further, circular chain steel is become charge bar with Ya Li Ji G, then charge bar is sent into resistance heated machine clamping energising and be heated to 630-730 ℃, again charge bar is sent into chaining movement tire with manipulator, crooked chaining ring forming, afterwards charge bar is sent into butt welding machine with manipulator and finish welding sequence, put into immediately after the deburring on the mold of press bench, exert pressure and to finish in the chain link with heart tire insertion brake forming.
Further, charge bar is heated to 680 ℃.
Adopt technical scheme of the present invention to have following technique effect:
1, the heavy compact flat vertical chain ring that is applicable to thinner seam of external exploitation at present is mainly to forge ring, and the upright ring that the applicant produces is with being pressed into flat chain link again behind the circular chain steel establishment welding fabrication, guaranteed that upright ring and flat ring are using stressed uniformity, help improving its mechanical performance, reach advanced world standards;
2, energy-saving effect is remarkable, and the power consumption of compacting ring is not enough forges 1/3 of ring, has reduced the waste of chain link material in forging process, utilizes the direct compression moulding of postwelding waste heat, has saved and has heated the electric energy that will consume behind the chain link once more;
3, forging ring is 1.5 times that compacting encircles with raw material, and be 4 times of compacting ring man-hour, and obviously compacting encircles and both reduced manufacturing cost, has also improved production efficiency simultaneously;
4, the compacting ring adopts the hot rolling material straight forming, and the metallic fiber streamline circularizes, and mechanical performance and the result of use of comparing chain link with the forging ring are good.
The specific embodiment
Embodiment 1:
The raw material of 9 meters of hot-finished material 23MnNiMoCr54 circular chain steel Φ 34mm length are become the long charge bar of 395mm with Ya Li Ji G, then charge bar is sent into resistance heated machine clamping energising and be heated to 680 ℃, directly send into chaining movement tire afterwards with manipulator, crooked chaining ring forming, send into butt welding machine with manipulator again and finish welding sequence, put into immediately after the deburring on the mold of press bench, heart tire is inserted in the chain link of brake forming, exert pressure, can finish the manufacturing of compacting flat ring.
The compact flat vertical chain ring technical parameter such as the following table that make:
| Chain link specification mm | Pitch P (mm) | Width (mm) | e max | ||
