It is dynamic to drive the first transfer roller 2 to rotate, and then tubing is fed into the second guide groove 39, feed speed control 0.3-0.6 meters/
Second.
B, circular hole punching：After tubing enters in the second guide groove 39, the minitype cylinder 20 that circular hole rushes the top of platform 13 starts, and pushes away
Movable slider 19 moves to the contact block 18 rushed with circular hole on platform 13 and contacted, and stamping cylinder 11 starts, and drives lower platen 10 to be pressed downward,
3 tons of down force pressure, so that contact block 18 is pushed with movable slider 19, and then the upper bolster 17 that circular hole is rushed into platform 13 is pressed downward and compressed
First spring, the punching of circular hole is carried out to tubing using the circular hole punch-pin 23 of the downside of upper bolster 17, after circular hole punching is finished, punching
Air cylinder 11 rises, and minitype cylinder 20 shrinks, and motion resets upper bolster 17 upwards under the reset response of the first spring；
C, square hole punching：After circular hole punching is finished, the first transfer roller 2 drives the meter per second of tubing 0.15 to feed a segment distance again
Afterwards, similarly, stamping cylinder 11 declines, and the minitype cylinder 20 that square hole rushes the top of platform 14 starts, and the punching of square hole, punching are carried out to tubing
2-5 tons of air cylinder stamping pressure.
D, side opening punching：When carrying out the punching of side opening, when upper bolster 17 declines, the first voussoir of the downside of upper bolster 17
27 also decline, and the lower general who has surrendered of the first voussoir 27 promotes the second voussoir 29, and the second voussoir 29 is under the promotion of the first voussoir 27, in opposite directions
Motion, promotes the move toward one another of connecting rod 30, and compresses the second stage clip 31, and then utilizes the side opening punch-pin 32 being connected with connecting rod 30
The tubing being pointed between two side opening punch-pin 32 carries out side punching, and after punching is finished, upper bolster 17 rises, and drives first
Voussoir 27 rises, under the reset response power of the second stage clip 31, and two side opening punch-pin 32 are dorsad moved, and completes the side to tubing
Punching, 3-6 tons of stamping cylinder stamping pressure.
E, tubing cutting：After side opening punching is finished, cutting bed 16 is according to circular hole punching and remote, the completion pair of square hole punching
The cutting of tubing, 2-5 tons of stamping cylinder stamping pressure during cutting.
F, tubing conveying：Tubing be cut finish after, the tubing processed advances to the second transfer roller 36, passes through second
Transfer roller 36 is transported to given place, transfer rate 0.3-0.6 meter per seconds.
The sliding block 19 offers first through hole 33 close to the side of minitype cylinder 20, is in minitype cylinder 20 contraction-like
State, first through hole 33 is located at the surface of the contact block 18 close to the side of minitype cylinder 20.When minitype cylinder 20 is in contraction-like
State, when sliding block 19 drives decline by top board, contact block 18 can be through first through hole 33 without being pressed downward by sliding block 19, such as
This, avoids the need for minitype cylinder 20 and sliding block 19 is all pulled away from into contact block 18, the flexible amplitude of minitype cylinder 20 is small, reaction is more
It hurry up, it is more efficient, and structure is also compacter.
The lower section of the die shoe 9 is provided with collection box 34, and the both sides of the collection box 34 are rotatably connected to pulley, described
Slide rail is provided with frame 1, the pulley is slidably connected on slide rail.Circular hole punch-pin 23 and square hole punch-pin 24 are rushed to tubing
The waste material being rushed out on Kong Shi, tubing advances to collection box 34 and is collected, when the garbage collection in collection box 34 completely after,
Collection box 34 skidded off from slide rail by scrap discharge, it is to avoid waste material is scattered everywhere.
The first guide groove 35 of fixed tubing, first guide groove are provided between the upper bolster 17 and die shoe 9
The second through hole coordinated with side opening punch-pin 32 is provided with 35.When being punched out and cutting, tubing can be fixed on first and lead
Into groove 35, it is to avoid larger impulsive force causes tubing to shift when punching pipes and cutting, and punching quality is more preferable.
The U-type groove 28 is fixedly connected with conduit 38, the conduit 38 close to the side of the first guide groove 35 and is lined with
Sliding bearing, the connecting rod 30 is slidably connected in conduit 38.The setting of conduit 38 causes connecting rod 30 in slip, to slide
More steady, it is to avoid sliding inclined, the setting of sliding bearing make it that friction is smaller when connecting rod 30 is slided in conduit 38, and noise is also more
It is small.
The second guide groove 39, the guide groove of the second guide groove 39 and first are fixedly connected with first transfer roller 2
35 on same straight line.The setting of second guide groove 39 so that when tubing is transmitted on the first transfer roller 2, pipe can be avoided
Material shifts and causes the non-type problem of punching, more preferable to the punching quality of tubing.
The circular hole punch-pin 23 and square hole punch-pin 24 are threaded on upper bolster 17, and the screw thread of side opening punch-pin 32 connects
It is connected in connecting rod 30.When in use, if desired the size of change circular hole punch-pin 23, square hole punch-pin 24 or side opening punch-pin 32 or
During person's shape, threaded connection facilitates the replacing of punch-pin；After prolonged use, circular hole punch-pin 23, square hole punch-pin 24 or
Side opening punch-pin 32 damages or is also convenient for after wearing and tearing the replacing of punch-pin.
The above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to preferred embodiment to this hair
It is bright to be described in detail, it will be understood by those within the art that, technical scheme can be modified
Or equivalent substitution, without departing from the objective and scope of technical solution of the present invention, it all should cover the claim in the present invention
Among scope.The technology of the invention not being described in detail, shape, construction part are known technology.
