Detailed Description
Fig. 1-4 show a concrete structure of a steel bar hoop bending machine, which comprises a main machine 1, a supporting feed chute 2 transversely arranged on the side of the main machine 1, and a vertical backup plate 3 vertically arranged above the supporting feed chute 2, wherein a machine head assembly transversely extends out of the side of the main machine 1, the machine head assembly corresponds to the supporting feed chute 2, and the vertical backup plate 3 inclines towards the main machine 1 and forms an acute angle with the horizontal plane.
The whole host 1 is of a rectangular structure, and the power mechanism is integrated in the case of the host 1, so that the structure of the whole machine is more concentrated and compact, and the size of the machine body is small, so that the whole machine can move, and the power mechanism is suitable for being flexibly used in a construction site. As shown in attached figures 2 and 3, the main operation position is arranged on one side of the main machine 1, wherein the supporting feeding chute 2 is arranged on one side of the operation position of the main machine 1 along the length direction of the main machine 1, and the groove-shaped structure is convenient for supporting the steel bars to be processed and dragging the steel bars to move along the length direction of the supporting feeding chute 2 by an operator. Wherein the aircraft nose subassembly also stretches out on one side of the operation position of host computer 1, vertical backup plate 3 vertically sets up operation position one side at host computer 1, vertical backup plate 3 links up with bearing chute feeder 2 in the bottom, the stretching out position of aircraft nose subassembly is corresponding with the position of bearing chute feeder 2, make dead axle 42 and pendulum shaft 43 all follow the horizontal extension of bearing chute feeder 2 promptly, and the upper edge of pendulum shaft 43 is with the bearing face of bearing chute feeder 2, just so make the processing position that the reinforcing bar of treating processing can pass the aircraft nose subassembly, and move along the length direction of bearing chute feeder 2, also can move or swing on vertical backup plate 3 along vertical. For preventing the reinforcing bar from inclining to the operator in the course of working, erect backup plate 3 wholly to host computer 1 an angle of slope slightly, make and be an acute angle between the horizontal plane of erecting backup plate 3 and host computer 1, can guarantee like this along erecting backup plate 3 removal or wobbling reinforcing bar focus lean on to erecting backup plate 3, and can not be partial to the operation position one side that is located host computer 1. The vertical backup plate 3 structure of the vertical arrangement changes the existing mode of transversely bending the steel bar into the processing mode of longitudinally bending the steel bar, and greatly improves the operation safety of the hoop bending machine because the movement track of the longitudinally bent steel bar avoids the body of an operator.
Further, an included angle between the vertical backup plate 3 and the host 1 in the horizontal direction is 72-75 degrees.
Considering the bending process and the ease with which an operator can remove the finished product, after many experiments, the angle is preferably 70 degrees. Because in the actual operation, often adopt three to four reinforcing bars to buckle simultaneously, many reinforcing bars can produce the inertia of moving in the process of buckling, because of the horizontal swing of probably producing of collision between each reinforcing bar moreover, so when being greater than 75 degrees, this kind of horizontal swing can make the reinforcing bar incline to the operator, takes place wounded's accident easily. When the angle is less than 72 degrees, the center of gravity of the finished product is far from the operator, so that the operator needs to take off the finished product from the vertical backup plate 3 with more effort.
Further, the head assembly comprises a rotating disc 41, a fixed shaft 42 positioned at the center of the rotating disc 41 and a swinging shaft 43 deviated from the center of the rotating disc 41, wherein the rotating plane of the swinging shaft 43 is parallel to the vertical backup plate 3.
The hydraulic mechanism integrated in the main machine 1 drives the rotating disc 41 to rotate, the fixed shaft 42 is positioned at the rotating center of the rotating disc 41 and rotates along with the rotation, the swing shaft 43 is positioned at the position deviated from the fixed shaft 42, a gap capable of containing a steel bar to be processed is reserved between the fixed shaft 42 and the swing shaft 43, the fixed shaft 42 rotates at the center of the rotating disc 41 along with the rotation of the rotating disc 41, the swing shaft 43 rotates around the center of the rotating disc 41, the steel bar to be bent is rotatably placed in the bearing feeding groove 2, the free end of the steel bar is clamped between the fixed shaft 42 and the swing shaft 43, the free end of the steel bar is bent and formed along with the swinging of the swing shaft 43 after the equipment is started, and the rotating plane of the swing shaft 43, namely the outer surface of the rotating disc 41 is parallel to or coplanar with the vertical backup plate 3, so that the bent end of the steel bar can lean against the vertical backup plate 3. After the swing shaft 43 is reset in the bending process, an operator continues to drag the steel bars forwards along the bearing feeding groove 2, the equipment is started again after the position is determined, and the bending of the next position is continued until the whole steel bar hoop is formed, and the operator easily takes down the workpiece from the vertical backup plate 3. In whole bending process, the weight of reinforcing bar is being supported by bearing silo 2 and the perpendicular backup plate 3 that the slope set up, and the operator only needs to implement for accomplishing next process and drags the reinforcing bar, and need not bear the gravity of whole reinforcing bar, has alleviateed the burden greatly for the operator. And the direction of buckling of reinforcing bar is all vertically gone on along erecting backup plate 3, and the operator is kept away from to the process of buckling, has avoided the operator probably to be injured at the in-process of buckling, has improved the security of the operation of buckling greatly.

When bearing chute feeder 2 sets up for the horizontal direction, the reinforcing bar stops or when removing in bearing chute feeder 2 difficult emergence abnormal slip, so safe and reliable more, the effective swing time of pendulum shaft 43 is shorter when pendulum shaft 43 is located dead axle 42 below, and efficiency is higher.
Furthermore, an auxiliary table 21 with adjustable height is arranged on the bearing feeding groove 2, and the top surface of the auxiliary table 21 is flush with the upper edge of the swing shaft 43.
Because the diameters of the steel bars processed on the construction site are different according to requirements, in order to enable the equipment to be suitable for the steel bars with various specifications, the gap between the swing shaft 43 and the fixed shaft 42 can be made as large as possible, namely, the equipment can be used for processing the steel bars with the common maximum diameter when the distance between the swing shaft 43 and the fixed shaft is the maximum, and when other steel bars with smaller diameters need to be processed, the sleeve with different outer diameters is sleeved on the swing shaft 43 to adjust the gap between the sleeve and the fixed shaft 42 so as to adapt to the steel bars with corresponding diameters. The auxiliary table 21 is arranged close to the machine head assembly, can be used for supporting and arranging the steel bars to be processed, and is convenient for clamping the end parts of the steel bars between the fixed shaft 42 and the swing shaft 73, so that the top surface of the auxiliary table 21 needs to be coplanar with the upper edge of the swing shaft 43, and in order to adapt to the steel bars with different diameters, the auxiliary table 21 can be adjusted in height by arranging adjusting screws and nuts which are matched with each other at the bottom.
Further, there are two sets of head components, and the sub-table 21 is located between the two sets of head components.
Because the steel bar hoop that uses commonly has a plurality of positions of buckling, when two sets of head assembly that set up, can also choose to buckle the other end of reinforcing bar, can minimize the reinforcing bar swing range of follow-up bending segment like this, also can provide the selection of a more process of buckling for the steel bar hoop of processing different shapes.
