Embodiment 1

[0038] 11. The rotating power source 11 is supported on the frame 1; at least two of the pressing wheels 2 are arranged on a depressing mechanism for adjusting their positions, and the depressing mechanism is arranged on the frame 1; the depressing mechanism is The eccentric shaft-type depressing mechanism is hinged to a pressure roller adjusting plate 3 , and the at least two pressure rollers 2 are hinged to the pressure roller adjusting plate 3 .

[0039] Working principle: When there is a deviation in the diameter of the same steel bar 12, the pressure wheel adjustment plate 3 swings at a slight angle to maintain the adjustment and follow-up of the size change of the steel bar 12, so that at least two of the pressure wheels 2 are always pressed. On bar 12.

Embodiment 2

[0041] On the basis of Embodiment 1, the number of the eccentric shaft pressing mechanism can be selected according to actual needs. Of course, the present invention is not limited to the cases enumerated in this embodiment.

[0042]If only one steel bar 12 is conveyed, the eccentric shaft type depressing mechanism can be formed into one group. At this time, a caulking groove 10 is arranged on the outer edge of the main driving wheel 8, and the at least two pressing wheels 2 They are arranged side by side along the feeding direction of the reinforcing bars 12 and pressed against the reinforcing bars 12 in the said one embedding groove 10 . When conveying a steel bar 12 of uneven thickness, the pressure roller adjustment plate 3 will rotate a certain angle to the pressure roller that cannot be pressed under the pressure of the eccentric shaft type pressing mechanism, and automatically adjust the balance state so that the two pressure rollers 2 can be compressed, and the reinfo...

Embodiment 3

[0045] On the basis of Example 1, such as figure 1 , 3 , 5, and 8, the eccentric shaft type depressing mechanism includes a depressing reciprocating drive mechanism 4 fixed on the frame 1, and the connecting rod 5 of the depressing reciprocating drive mechanism 4 is connected to one end of the eccentric shaft 6, and the eccentric shaft 6 The other end of the slide plate 7 is movably connected; the slide plate 7 is hinged with the pressure roller adjustment plate 3, and the pressure roller adjustment plate 3 is hinged with at least two pressure rollers 2, and at least two pressure rollers 2 are along the feed of the steel bar 12 Directions are set front to back and side by side.

[0046] The depressing reciprocating drive mechanism 4 is an air cylinder, an oil cylinder, a lead screw, a screw rod or an electric pressing device driven by a motor. In this implementation, the preferred cylinder is simple in structure and convenient in maintenance.

[0047] Such as image 3 , ...

Abstract

The invention relates to a hoop bending machine, in particular to a hoop bending machine provided with an eccentric shaft type pressing-down mechanism. The hoop bending machine comprises the eccentric shaft type pressing-down mechanism which comprises a pressing-down reciprocating drive mechanism. A connecting rod of the pressing-down reciprocating drive mechanism is connected with one end of an eccentric shaft, and the other end of the eccentric shaft is connected with a sliding plate. The sliding plate is hinged to a pressing wheel adjusting plate. The eccentric shaft comprises a connecting shaft part, a key connecting part arranged at one end of the connecting shaft part, and an eccentric part arranged at the other end of the connecting shaft part. The key connecting part is in key connection with an eccentric shaft sleeve. The eccentric shaft sleeve is welded to one end of the connecting rod. The eccentric part is movably connected to a sliding plate. Each sliding plate is provided with an eccentric fixing hole. The eccentric part is located in the eccentric fixing holes. The outer surface of each sliding plate is sunken inwards to form a sunken part. The pressing wheel adjusting plate is hinged to the sunken parts. The pressing wheel adjusting plate and the upper edges of the sunken parts are in clearance fit. At least two pressing wheels are hinged to the pressing wheel adjusting plate. The hoop bending machine is simple in structure and reduces friction frequency.

Description

technical field [0001] The invention relates to a hoop bending machine, in particular to a hoop bending machine with an eccentric shaft pressing mechanism. Background technique [0002] The hoop bending machine is generally composed of a feeding mechanism, a straightening mechanism, a traction mechanism, a bending mechanism and a cutting mechanism. The feeding mechanism stops working after feeding the steel bar into the steel bar hoop bending machine. Under the traction of the traction mechanism, the steel bar is first straightened by the straightening mechanism, then bent into a preset shape by the bending mechanism, and finally the steel bar bent into a certain shape passes through After the cutting mechanism is cut, it can be used to assemble the steel skeleton. [0003] Chinese patent application No. 21313448.9 discloses a torsion-resistant steel bar feeding mechanism, which includes a frame and a traction mechanism arranged on the frame. The traction mechanism includes...
