Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, specifically a metal buckle bending machine. Background Technology

[0002] As a key connecting component in shipbuilding, construction, hoisting, and mining, the bending quality of the U-shaped body of metal shackles directly affects the rated load and service life. According to statistics, the global shackle market size has exceeded US$2 billion per year. In order to ensure the bending effect of the U-shaped body of metal shackles, the development of a metal shackle bending machine is of great practical significance.

[0003] A metal buckle bending machine, as described in reference announcement number CN207681238U, includes a machine bed, a servo motor, a transmission belt, a ball screw pair, a drive slider, an upper connecting rod, an eccentric shaft, a lower connecting rod, and a worktable, all mounted on the machine bed. The servo motor is connected to the ball screw pair via the transmission belt. The drive slider slides on the screw and is driven to slide within the machine bed via the upper connecting rod, eccentric shaft, and lower connecting rod. In this metal buckle bending machine, round steel is fixed to the worktable, and a punch is fixed to the slider. The motor drives the ball screw pair, causing the drive slider to move along the screw, thereby driving the upper connecting rod, eccentric shaft and lower connecting rod to move, which in turn drives the slider to slide along the machine bed, and finally the punch bends the round steel into shape to produce a shackle. This metal shackle bending machine has a simple structure, high transmission efficiency, high precision, is easy to operate, and has excellent energy-saving effect. As can be seen from the above, although this bending machine can be well applied, it is usually not convenient to bend steel parts into a U-shaped structure electrically, which affects the bending effect of the bending machine on steel parts, and further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a metal buckle bending machine to solve the problem mentioned in the background art that although bending machines can be used well, they are usually not convenient for electric bending of steel parts into a U-shaped structure, thus affecting the bending effect of the bending machine on steel parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal buckle bending machine, comprising a base plate, two bases fixedly installed on one side of the top of the base plate, each base plate having a column at its top, a top seat installed at the top of each column, a top frame fixedly installed on the top of each of the two top seats, a support frame fixedly installed at the center of the top of the top frame, a bending head installed at the bottom of the support frame, a positioning frame installed on the top of the base plate between the bases, a lower connecting arm rotatably installed on the top of the positioning frame, a tripod rotatably installed on the end of the lower connecting arm away from the positioning frame, an upper connecting arm rotatably installed on the top of the tripod, a component holder rotatably installed on the top of the upper connecting arm, two bending rods provided above the component holder, diagonal braces fixedly installed at both ends of each bending rod, the bottom end of the diagonal braces fixedly connected to the top of the component holder, and a control panel fitted into one side of the top of the base plate.

[0006] Preferably, a limiting rail is provided at the top of the base plate on one side of the positioning frame, and a rail seat is slidably installed at the top of the limiting rail. The position of the rail seat can be adjusted by sliding it at the top of the limiting rail, so as to adjust the position of the telescopic cylinder.

[0007] Preferably, a limiting plate is fixedly installed on the outer wall of the limiting rail away from the positioning frame, and a linkage frame is provided at the top of the rail base. The linkage frame is used to accommodate the telescopic cylinder.

[0008] Preferably, a telescopic cylinder is rotatably mounted on the inner wall of the linkage frame. The input end of the telescopic cylinder is electrically connected to the output end of the microcontroller inside the control panel. One end of the telescopic cylinder is movably connected to a connector. The end of the connector away from the telescopic cylinder is rotatably connected to the outer wall of the tripod. The telescopic cylinder is used to drive the tripod to translate and rotate.

[0009] Preferably, two locking bolts are threadedly installed on the outer wall of one side of the rail seat. One end of the locking bolt passes through the rail seat and is threadedly connected to the threaded hole on the outer wall of the limiting rail. The locking bolts are used to position the rail seat on top of the limiting rail.

[0010] Preferably, the inner wall of each column is provided with a slide rail, and the outer walls on both sides of the shelf are provided with rail blocks. The rail blocks are slidably connected to the slide rails, so as to limit the movement range of the shelf.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the metal shackle bending machine not only ensures the bending effect of the metal shackle steel parts when the bending machine is used, but also reduces the phenomenon of deviation when the placement frame is lifted and lowered, and improves the convenience of using the bending machine.

[0012] (1) By placing the steel part on the top of the two bending rods, and then starting the telescopic cylinder, the tripod is driven to move to the left through the connector. At this time, the angles of the lower arm, connector and telescopic cylinder change accordingly, and the tripod is driven to move the placement frame upward through the upper arm, so that the steel part is bent upward into a U-shape by the two bending rods at the bottom of the bending head, thereby ensuring the bending effect of the bending machine on the metal shackle steel part when it is used.

[0013] (2) By sliding the rail block and the slide rail, when the placement rack moves up and down, the rail block set on the outer wall of the placement rack slides synchronously on the inner wall of the slide rail to limit the movement range of the placement rack, thereby reducing the phenomenon of deviation when the placement rack moves up and down.

[0014] (3) By loosening the locking bolt, the sliding rail seat is located on the top of the limit rail. After the rail seat is adjusted to the designated position, the locking bolt is tightened so that one end of the locking bolt is screwed into the threaded hole on the outer wall of the limit rail, so that the rail seat is positioned on the top of the limit rail. The position of the telescopic cylinder can be adjusted as needed according to the thickness of the steel parts and the usage requirements, thereby improving the convenience of using the bending machine.

[0024] In use, the position of the telescopic cylinder 12 can be adjusted by sliding the adjustment rail seat 22 on the top of the limit rail 13;

[0025] A limit plate 14 is fixedly installed on the outer wall of the limit rail 13 on the side away from the positioning frame 9, and a linkage frame 24 is provided at the top of the rail base 22.

[0026] In use, the telescopic cylinder 12 is positioned by setting up the linkage frame 24.

[0027] A telescopic cylinder 12 is rotatably mounted on the inner wall of the linkage frame 24. The input end of the telescopic cylinder 12 is electrically connected to the output end of the microcontroller inside the control panel 2. One end of the telescopic cylinder 12 is movably connected to a connector 15.
