Description
The utility model relates to a kind of screw thread steel processing machine, particularly a kind of reinforcing bar die head threading machine of being made up of flat chasing tool cutting mechanism, cooling system.
At present, the cooling system that existing reinforcing bar die head threading machine is, complex structure, sealing is poor, can not rinse the iron filings of processing reinforcing bar well, has influenced accuracy of thread.In addition, existing reinforcing bar die head threading machine, the flat chasing tool that the has lock function that do not rise automatically, in the process, the adjusting of flat chasing tool need manually be finished; Therefore the complex structure that has, has influenced working (machining) efficiency.
The purpose of this utility model provides a kind of flat chasing tool cutting mechanism and adopts inner cooling system simple in structure, good airproof performance, and has the reinforcing bar die head threading machine of the latch mechanism that rises automatically simple in structure.
The technical solution of the utility model is: a kind of reinforcing bar die head threading machine, by radially flat chasing tool cutting head, radially flat chasing tool, flat chasing tool seat, reductor, electric control box, vice frame and frame are formed, radially flat chasing tool cutting head is installed on the output shaft of reductor, radially flat chasing tool is installed on the flat chasing tool seat, reductor, the vice frame is installed on the frame, electric control box is installed in the frame, the internal cooling system that it is characterized in that radially flat chasing tool cutting head is by positioning sleeve, cutting body, block, receiver, sedimentation basin and water tank are formed, positioning sleeve is the bearing gland of reductor, cutting body seals in positioning sleeve, blocked by block, the cutting body external diameter has sealing ring, cannelure and axial osculum, the axial osculum of cannelure communicates with the cannelure of block and axial delivery port, receiver is positioned at the top of water tank, communicates with water tank through the frame downpipe.The cooling fluid of the internal cooling system of radially flat chasing tool cutting head is carefully filtered through receiver, downpipe coarse filtration and tank lid, enters sedimentation basin, filters through diaphragm plate is smart again, utilizes again.Radially flat chasing tool and flat chasing tool seat are installed in the gathering sill of cutting body, flat chasing tool seat be positioned the ring and spring fix.Radially flat chasing tool has the latch mechanism that rises automatically, and the latch mechanism that rises automatically is made up of gag lever post, limited block, position-limited wheel, and gag lever post is contained on the vice frame, and limited block is contained on the gag lever post, and position-limited wheel is contained on the limited block.Electric control box is sealed in the frame.
Operation principle of the present utility model is: inner cooling system is made up of water pump, positioning sleeve, pipe joint, cutting body and block.Positioning sleeve is the bearing gland of reductor, and cutting body seals in positioning sleeve, is fixed on the speed reducer output shaft, is blocked by block, uses bolted.The cutting body external diameter has cannelure and axial osculum, and there is sealing ring on the cannelure both sides, and the axial osculum of cannelure is identical with the cannelure of block and axial osculum.When pump working, cooling fluid flows into cutting head, cool off flat chasing tool and go out iron filings, fall in the receiver,, arrive the water tank receiver again through the coarse filtration of receiver and frame downpipe, the sedimentation basin that enters water tank through meticulous filtration precipitates, post precipitation, becomes clean cooling fluid and enters water tank after the processing from the smart filtering holes on the diaphragm plate top of water tank.
The flat chasing tool latch mechanism that rises is made up of gag lever post, limited block and position-limited wheel, and position-limited wheel is positioned on the limited block, and gag lever post is fixed on the vice frame, and limited block is fixed on the gag lever post.When reinforcing bar was worked into predetermined length, the locating ring that position-limited wheel blocks on the slip cap advanced, and cutting body continues to the cutter position that rises of flat chasing tool seat, and spring is with flat chasing tool seat peace chasing tool spreading.By rotating handles, when the gland on the slip cap bumped against position-limited wheel, locating ring forced flat chasing tool seat to shrink to axis direction again, with the reduction of flat chasing tool seat peace chasing tool.
The utility model has the advantages that: owing to adopted inner cooling system simple in structure, good airproof performance, improved the precision of machining screw, flat chasing tool has the lock function that rises automatically, has alleviated the work degree, has improved production efficiency.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the local amplification view of cutting head 5 among Fig. 1;
Fig. 3 is that the A of Fig. 2 is to view.
The cutting mechanism of reinforcing bar die head threading machine is made up of motor 11, reductor 9, cutting head 5, and motor 11 is contained in the input of reductor 9, and cutting head 5 is contained on the output shaft of reductor 9, and they are contained on the frame 16 by the leading truck bearing 7 of reductor 9.
Cutting head 5 is made up of cutting body 24, chasing tool seat 31, radially flat chasing tool 29, spring 30, locating ring 20, slip cap 21, gland 23.Radially flat chasing tool 29 usefulness bolted are to chasing tool seat 31, the chasing tool seat is inlaid in the cross gathering sill of cutting body 24, and 8 springs 30 are supporting 4 chasing tool seats 31 in the spring base of cutting body 24, position, top ring 20 is binding round chasing tool seat 31, is fixed by bolts on the slip cap 21.
Feed mechanism is made up of gear, tooth bar, spanner 8.Gear is installed on 8 of the spanners, and with the tooth bar engagement, red is fixed on reductor 9 bottoms, pulls spanner 8 and can make cutting head 5 feedings.
