Problems solved by technology

[0007] The disadvantages are: the disadvantages of the worm gear hoop bending machine: manual assistance is required in the bending process of the steel bar, and the steel bar needs to be lifted and shifted every time it is bent, which consumes a lot of physical strength; the rotating shaft needs to be reset once every time it is bent, which cannot One-time molding, low efficiency; bending point and bending angle are manually controlled, low precision
[0010] The disadvantages are: the bending process of the steel bar needs manual assistance, and every time it is bent, the steel bar needs to be lifted once for displacement, which consumes a lot of physical strength; the automatic reset shaft cannot be formed at one time, and the efficiency is low
[0013] The disadvantages are: large volume (generally more than 2m in length), high price (average price per unit is more than 40,000)

Embodiment 1

[0046] Such as Figure 1-Figure 4 As shown, a new steel hoop bending machine includes a workbench 1, the upper end of the workbench 1 is oppositely provided with a rotating bending groove 2 that runs through the workbench 1, and the workbench 1 between the two rotating bending grooves 2 is provided with a The positioning device for the bending of the steel bar 27, the lower end of the workbench 1 between the ends of the two rotating bending grooves 2 is provided with a downward trapezoidal slideway 9, and the bottom of the workbench 1 is provided with a rotating device, which includes a rotating telescopic shaft 3 and a Because of the linkage device that drives the rotating telescopic shaft 3 to move along the rotating bending groove 2 and the trapezoidal slideway 9, the upper end of the rotating telescopic shaft 3 passes through the rotating bending groove 2 and cooperates with the positioning device to drive the steel bar 27 to bend, and the rotating bending groove 2 is to ro...

Embodiment 2

[0050] This embodiment is basically the same as Embodiment 1, the difference is: as Figure 1-Figure 6 As shown, the rotating and bending groove 2 includes a longitudinal movement groove 10 and a transverse movement groove 11 positioned at both ends of the longitudinal movement groove 10. 9 includes two inverted trapezoidal slides 12 vertically arranged at the lower end of the workbench 1, the short bottom of the inverted trapezoidal slides 12 faces downward, and the lower end of the inverted trapezoidal slides 12 includes a straight section and an inclined section arranged at both ends of the straight section, Two inverted trapezoidal slide plates 12 are respectively arranged on two sides of the end of the transverse movement groove 11 away from the end of the longitudinal movement groove 10 . The rotating curved groove 2 and the trapezoidal slideway 9 form a closed parallelogram.

[0051] The rotating telescopic shaft 3 includes a moving shaft 13, which is provided with a d...

Embodiment 3

[0056] A method for using the novel steel bar hoop bending machine described in Embodiments 1 and 2, comprising the following steps:

[0057] (1) The reinforcing bar 27 is placed between the fixed bending shaft 4 and the fixed retaining shaft 8, and one end of the reinforcing bar 27 is placed on one side of the baffle plate 6;

[0058] (2) Start the rotating drive mechanism 28 to drive the rotating shaft 25 to rotate, and the rotating shaft 25 drives the rotating telescopic shaft 3 to move along the rotating curved groove 2 and the trapezoidal slideway 9 through the linkage device:

[0059] 1) Turn the upper end of the telescopic shaft 3 to move along a longitudinal movement groove 10 to a fixed bending axis 4, change the moving direction by 90° to enter a transverse movement groove 11, and simultaneously drive the steel bar 27 to complete a bending around the fixed bending axis 4;

[0060] 2) The rotating telescopic shaft 3 moves along the transverse movement groove 11 to the...

Abstract

The invention provides a novel steel bar hoop bending machine and a using method thereof. The novel steel bar hoop bending machine comprises a working table, wherein rotating bending grooves are oppositely arranged at the upper end of the working table, a positioning device used for bending a steel bar is arranged at the part, between the two rotating bending grooves, of the working table, the lower end of the part, between the ends of the two rotating bending grooves, of the working table is provided with a downward trapezoidal slideway, a rotating device is arranged below the working table,the rotating device comprises a rotating telescopic shaft and a linkage device used for driving the rotating telescopic shaft to move along the rotating bending grooves and the trapezoidal slideway, and the upper end of the rotating telescopic shaft penetrates through the rotating bending grooves and are matched with the positioning device for driving the steel bar to be bent. According to the novel steel bar hoop bending machine and the using method thereof, a hoop is formed once, so that manual intervention is reduced, the hoop bending precision is high, the manual work ratio is small, the efficiency is high, the size is small, and the price is low.

Description

technical field [0001] The invention relates to the technical field of steel bar hoop bending equipment, in particular to a novel steel bar hoop bending machine and a using method thereof. Background technique [0002] Bending steel bars are often used in the construction process in the field of industrial and civil construction. It is often not an easy task to obtain such steel bars. We need to bend straight steel bars with a steel bar bending machine to obtain them. Steel bar bending machine is an indispensable tool in engineering construction. With the advancement of science and technology, the types of hoop bending machines are gradually increasing. According to the type of power control, it is mainly divided into manual operation type, motor control type and microcomputer control hydraulic drive type: (1) Manual operation type: easy to use, simple to operate, cheap, suitable for processing a small amount of stirrups; (2) motor Control type: small size, easy to move, r...
