Semicircular in shape offers semicircular arc groove 31 on the curved wall of briquetting 3, makes the contact area bigger of briquetting 3 and steel pipe,
Make being more uniformly stressed for steel pipe.
As shown in figure 3, briquetting 3 is fixedly connected with conflict block 33 on the side wall of engine base 1, opened up on the side wall of engine base 1
There is the vertical opening 12 being adapted to conflict block 33（Referring to Fig. 1）, conflict block 33 enters through opening inside engine base 1.Inside engine base 1
Be rotatably connected to two screw rods being vertically arranged 41, the thread rotary orientations of two screw rods 41 on the contrary, two screw rods 41 be equipped with it is same
A limited block 4 is simultaneously threadedly coupled with limited block 4, and the bottoms of two screw rods 41 is respectively fixedly connected with there are one connection gear 43, and two
A connection gear 43 engages.Driving motor 44 is fixed on engine base 1, motor gear is fixedly connected on the main shaft of driving motor 44
441, motor gear 441 is engaged with one of connection gear 43；When driving motor 44 starts, a connection gear 43 is driven
It rotates, because two connection gears 43 engage, two screw rods 41 are rotated synchronously with opposite rotation direction, and because two
The thread rotary orientation of screw rod 41 is on the contrary, so rise or fall limited block 4.
As shown in figure 3, limited block 4, at vertical opening 12, conflict block 33 enters the one of engine base 1 through vertical opening 12
End is located at directly over limited block 4 and between two screw rods 41.Hydraulic cylinder 32 drives briquetting 3 to push conflict block when steel pipe is bent
33 contact on limited block 4, so that the stopping of briquetting 3 continues to move down；The height of limited block 4 is adjusted using screw rod 41, from
And the stroke that briquetting 3 is controlled to push, and then the degree that steel pipe is controlled to bend, the radian of steel pipe after control is bent.
As shown in figure 3, when hydraulic cylinder 32 drives the pushing of briquetting 3, larger pressure can be generated between conflict block 33 and limited block 4
Power, the damage of conflict block 33 and limited block 4, conflict block are stained with rubber sheet gasket 331 on 33 lower surface during in order to reduce pushing；It is limiting
Infrared ray limit switch 42 is fixedly connected on the block 4 of position, infrared ray limit switch 42 is electrically connected with hydraulic cylinder 32, when conflict block 33
When being contradicted with limited block 4, when infrared ray limit switch 42 triggers, hydraulic cylinder 32 is stopped, during so as to be further reduced pushing
The damage of conflict block 33 and limited block 4.
As shown in Figure 1, engine base 1 offers mounting groove 11, support shaft 2 is located in mounting groove 11,11 both sides side wall of mounting groove
On open up there are two sliding slot 13, in horizontally disposed and in same level, sliding slot is set two sliding slots 13 on 13 lower face
There are several card slots 131（Referring to Fig. 2）, the both ends of support shaft 2 are placed in respectively in the card slot 131 of two side chutes 13；By that will prop up
Support axis 2 is placed in different card slots 131, so as to change the distance between two support shafts 2, is made with the cooperation of limited block 4
With so as to steel pipe to be curved to the arc of more different radians.
As shown in figure 4, being arranged with support roller 21 in support shaft 2, support roller 21 is with support shaft 2 in rotation connection, support roller
The annular groove 211 identical with outer diameter of steel pipes is offered on 21 annular sidewall；When bending steel pipe, steel pipe can be placed in annular
In slot 211, make the contact area bigger of support roller 21 and steel pipe, make being more uniformly stressed for steel pipe, when reducing steel pipe press-bending
Situation about being crushed at stress occurs.
Specific work process：The height of the spacing and limited block 4 between two support shafts 2 is adjusted, then places steel pipe
In in support roller 21 and being placed in annular groove 211, then starting hydraulic cylinder 32 makes it that briquetting 3 be promoted to push, right using briquetting 3
Steel pipe applies downward pressure, and the support roller 21 positioned at both sides applies steel pipe upward support force, so that tube bending；
Conflict block 33 is contradicted with limited block 4 after briquetting 3 is depressed into certain stroke, and triggering infrared ray limit switch 42, hydraulic cylinder 32 stops
Only push.
