Abstract
The invention discloses a correcting mechanism of an automatic hoop bending machine for reinforcing bars, which comprises a collecting frame on one side of a main unit of the hoop bending machine. A retaining plate used for supporting a bending end of a reinforcing bar is mounted on the collecting frame, a pressure plate is arranged on the bending end of the reinforcing bar and connected with a reciprocating drive mechanism, and the reciprocating drive mechanism drives the pressure plate to press or release the bending end of the reinforcing bar and is disposed on the collecting frame. The correcting mechanism has the advantages that the correcting mechanism overcomes defects of the prior art, and is capable of effectively correcting and fixing the reinforcing bar with the bending end, keeping the bending end and the other end of the reinforcing bar to be bent on the same plane, effectively preventing twist of the two ends of the reinforcing bar during bending and improving bending quality of the reinforcing bar.
Description
Technical field
What the present invention relates to is steel-bar automatic hoop bender, particularly be the straightening mechanism of steel-bar automatic hoop bender.
Background technology
Steel-bar automatic hoop bender is the automatic processing device that bar bending is become the difformity stirrup, fields such as steel-bar automatic hoop bender extensive use and urban construction, transport development.The prior art steel-bar automatic hoop bender comprises: haulage gear, straightening mechanism, bending mechanism, cutting mechanism, loopback mechanism and the frame that connects material.
Said loopback mechanism is at bending mechanism and connect material between the frame; The curved forming ends (being reinforcing bar one end) of reinforcing bar is continued to transfer forward by loopback grips reinforcing bar after the bending mechanism brake forming; When reinforcing bar treats that curved end (being the reinforcing bar other end) is shifted into the bending of hoop bending body, carry out bending once more, make the first order buckling moulding of reinforcing bar two ends.The said frame that connects material is used for the device of the curved forming ends (being reinforcing bar one end) of reinforcing bar of supplemental support brake forming, when reinforcing bar is treated curved end (being the reinforcing bar other end) when being bent, limits moving of the curved forming ends (being reinforcing bar one end) of reinforcing bar, prevents its distortion.
Fig. 6 is the material receiving mechanism sketch map of prior art steel-bar automatic hoop bender.
The frame that connects material of prior art steel-bar automatic hoop bender comprises: frame 19 connects material; On frame 19 inclined planes that connect material, be fixed with baffle plate 19a, the curved forming ends 16b of the reinforcing bar after support bends moulding on the said baffle plate 19a; Said reinforcing bar 16 is set at the material receiving mechanism control on the frame 19 that connects material.
Said material receiving mechanism comprises: connect material bent plate 14 with drive the cylinder 10 that connects material that the bent plate 14 that connects material is opened or closed; The said bent plate 14 that connects material is the bent plates that cross section is a square, holds reinforcing bar 16 when the end face of a right-angle side of the bent plate 14 that connects material contacts with baffle plate 19a, and reinforcing bar 16 falls when connecting material bent plate 14 when opening; Another right-angle side of the said bent plate 14 that connects material is fixed on an end of the fixed head 13 that connects material; The other end of fixed head 13 of connecting material is hinged on the piston rod of the cylinder 10 that connects material through the first hinge 11a that connects material; The fixed head 13 that connects material itself is fixedly supported on fixedly on the major axis 21; Said fixedly major axis 21 two ends are hinged on respectively on the bearing block 17, and said bearing block 17 is fixed on the frame 19 that connects material; The cylinder body of the said cylinder 10 that connects material is hinged on the frame 19 that connects material through the second hinge 11b that connects material.
After reinforcing bar treats that curved end (being the reinforcing bar other end) 16a is by the hoop bending body brake forming; The bent plate 14 that connects material drives down along with fixed head 13 rotations that connect material at the cylinder 10 of connecting material; When the bent plate 14 that connects material that rotates left baffle plate 19a, the reinforcing bar 16 after the brake forming just drops to be taken in the basket.
There is following defective in the frame that connects material of above-mentioned prior art steel-bar automatic hoop bender:
Because structure is limit; The space length that the bent plate 14 medial roof identity distance reinforcing bars that connect material have been bent forming ends 16b is bigger; The curved forming ends 16b of reinforcing bar after suffered torsion can be delivered to brake forming when reinforcing bar is treated curved end (being the reinforcing bar other end) 16a by the hoop bending body bending; Make the curved forming ends 16b of reinforcing bar swing arbitrarily occur at bent plate 14 inner spaces that connect material and reverse, the two ends of causing bar bending cause the quality of moment reinforcement to descend not in same planar shaping.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology; Provide the curved forming ends of a kind of reinforcing bar spacing fixing to brake forming; Make it to treat that with crooked reinforcing bar curved end is in same plane, guarantee the straightening mechanism of the steel-bar automatic hoop bender that reinforcing bar two ends after the bending are in the same plane.
The technical scheme that solves the problems of the technologies described above is: a kind of straightening mechanism of steel-bar automatic hoop bender; Said straightening mechanism comprises: the frame that connects material that is positioned at hoop bender main frame one side; Connect material the baffle plate of the curved forming ends of spacer bar is housed on the frame, on the curved forming ends of reinforcing bar, be provided with pressing plate, this pressing plate connects reciprocating drive mechanism; Said reciprocating drive mechanism driving pressing plate compresses or loosens the curved forming ends of reinforcing bar, and this reciprocating drive mechanism is arranged on the frame that connects material.
The invention has the beneficial effects as follows: the present invention overcomes the deficiency of prior art; Reinforcing bar to one end of brake forming can be ajusted fixing effectively; Make it with crooked other end reinforcing bar place at grade; Can effectively avoid the reinforcing bar bending two ends twisted phenomena to occur, improve the quality of bar bending.
