Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to an adjustable steel structure bending machine. Background Art

[0002] Bending machines are important equipment for bending and forming workpieces in the sheet metal industry. Their main function is to press steel plates into parts of various shapes according to process requirements. According to the operation mode, bending machines can be mainly divided into manual bending machines, hydraulic bending machines and CNC bending machines. Among them, manual bending machines can be divided into mechanical manual bending machines and electric manual bending machines; hydraulic bending machines can be divided into torsion axis synchronization, mechanical-hydraulic synchronization and electro-hydraulic synchronization according to the synchronization mode, and can be divided into upper-moving type and lower-moving type according to the movement mode.

[0003] Existing bending machines have the following disadvantages in actual operation. The bending angle usually requires the operator to judge and adjust based on experience, which makes the operation dependent on the individual skill level. Due to the subjective judgment and adjustment of the operator, the accuracy of the bending machine is often not high, and it cannot be guaranteed that each bent part achieves the expected effect. There may be angle deviation or inconsistency.

[0004] Therefore, the utility model provides an adjustable steel structure bending machine to solve the above problems. Utility Model Content

[0005] The utility model aims to provide an adjustable steel structure bending machine to solve the problem in the background technology that the bending accuracy of the existing bending machine cannot be accurately controlled.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an adjustable steel structure bending machine, comprising a bending arm, a fixing plate is arranged on the bending arm, and a clamping mechanism is arranged on the fixing plate.

[0007] In order to solve the problem that the bending accuracy of the existing bending machine cannot be accurately controlled, a scale plate is provided on the fixed plate, a guide rail is provided on the scale plate, a limit mechanism is slidably installed on the guide rail, the limit mechanism includes a limit cylinder, a through opening is provided in the limit cylinder, a locking assembly is provided in the limit cylinder, and a ball is provided at the bottom of the limit cylinder. By arranging the scale plate, the guide rail and the limit mechanism on the fixed plate, the bending arm can be combined with the scale line under the action of the limit mechanism, which can effectively solve the problem that the bending accuracy of the existing bending machine cannot be accurately controlled.

[0008] As a further improvement of the technical solution, the locking assembly includes a sleeve, the sleeve is fixedly connected to the top of the limit cylinder, a slot cylinder is fixedly connected inside the sleeve, a pressing rod is slidably connected to the top of the slot cylinder, a rebound rod is slidably connected to the bottom of the slot cylinder, one end of the spring is fixedly connected to the bottom of the rebound rod, and the other end is fixedly connected to the top of the damping disk. By setting the locking assembly, the limit mechanism can be adjusted steplessly to meet the requirements of the bending arm for bending parts with different precisions.

[0009] As a further improvement of the technical solution, the scale plate is evenly provided with a plurality of scale lines, and the zero degree scale line is aligned with the starting position of the bending arm. By providing the scale plate and the zero degree scale line, the scale plate is provided with a plurality of scale lines, so that the bending arm can set the bending angle according to the demand during the bending process.

[0010] As a further improvement of the technical solution, the ball is rotatably connected to the bottom of the limiting cylinder, and the volume of the exposed part of the ball is much smaller than the volume of the ball placed inside the limiting cylinder, and a gap is formed between the ball and the limiting cylinder. By arranging the ball at the bottom of the limiting cylinder, not only can the limiting cylinder slide along the guide rail on the dial, but also can support and limit the limiting cylinder.

[0011] As a further improvement of the technical solution, the shape of the through opening is adapted to the shape of the guide rail.

[0012] As a further improvement of the technical solution, the bottom of the damping disc is made of a material with a high friction coefficient. By setting the bottom of the damping disc to be a material with a high friction coefficient, when the damping disc presses down the guide rail, it can better position the limit cylinder, thereby facilitating a better limit effect on the bending arm.

[0016] 3. This adjustable steel structure bending machine has a ball bearing arranged at the bottom of the limit cylinder, which not only enables the limit cylinder to slide along the guide rail on the dial, but also supports and limits the limit cylinder.

[0017] 4.

[0030] See also Figure 1 As shown, the purpose of this embodiment is to provide an adjustable steel structure bending machine, including a bending arm 10, on which a fixed plate 20 is arranged, and on which a clamping mechanism 50 is arranged; the clamping mechanism 50 clamps the bending part.

[0031] For further information, see Figure 1-Figure 3 As shown, a scale plate 30 is arranged on the fixed plate 20, a guide rail 40 is arranged on the scale plate 30, a limiting mechanism 60 is slidably installed on the guide rail 40, the limiting mechanism 60 includes a limiting cylinder 601, a through opening 603 is arranged in the limiting cylinder 601, a locking assembly 602 is arranged in the limiting cylinder 601, and a ball 604 is arranged at the bottom of the limiting cylinder 601; the bending arm 10 starts by aligning the zero degree mark on the scale plate 30.

[0032] For further information, see Figure 3-Figure 5As shown, the locking assembly 602 includes a sleeve 6021, which is fixedly connected to the top of the limiting cylinder 601, a slot cylinder 6023 is fixedly connected inside the sleeve 6021, a pressing rod 6022 is slidably connected to the top of the slot cylinder 6023, a rebound rod 6024 is slidably connected to the bottom of the slot cylinder 6023, one end of a spring 6025 is fixedly connected to the bottom end of the rebound rod 6024, and the other end is fixedly connected to the top of the damping disk 6026; at this time, the operator starts to press the button on the limiting mechanism 60 according to the bending angle of the bending piece. The rod 6022 is pressed to disengage the damping disc 6026 inside the limit cylinder 601 from the guide rail 40; then the limit cylinder 601 is moved to the position of the angle scale line that needs to be bent and stops, and the limit cylinder 601 is moved. Under the dual limit of the ball 604 and the guide rail 40, the limit cylinder 601 can only slide along the guide rail 40 without turning over, and the ball 604 will roll along the scale plate 30; when the limit cylinder 601 reaches the specified scale line position, the pressing rod 6022 is pressed. At this time, the state of the locking assembly 602 changes from Figure 5 State A in the diagram changes to state D via states B and C, at which time the rebound rod 6024 drives the damping disc 6026 upward into the relatively shallow slot of the slot tube 6023 under the action of the spring 6025; the rebound rod 6024 moves a certain distance away from the pressing rod 6022 compared to state A, thereby driving the damping disc 6026 to press the guide rail 40; at this time, when the operator bends the bending part, the bending arm 10 stops bending immediately when it hits the limit tube 601.

[0033] For details, please refer to Figure 1 As shown, a plurality of scale lines are evenly arranged on the scale plate 30 , and the zero degree scale line is aligned with the starting position of the bending arm 10 .

[0034] For further information, see Figure 3 As shown, the ball 604 is rotatably connected to the bottom of the limiting cylinder 601 , and the volume of the exposed portion of the ball 604 is much smaller than the volume of the ball 604 placed inside the limiting cylinder 601 , and a gap is formed between the ball 604 and the limiting cylinder 601 .

[0035] Also, see Figure 2 and Figure 3 As shown, the shape of the through opening 603 is adapted to the shape of the guide rail 40 .

[0036] In addition, see Figure 3 As shown, the bottom of the damping plate 6026 is made of a material with a high friction coefficient.

[0037] The specific working principle is as follows:

[0038] The clamping mechanism 50 clamps the bending piece, and the bending arm 10 begins to align with the zero degree mark on the scale plate 30; at this time, the operator begins to press the pressing rod 6022 on the limit mechanism 60 according to the bending angle of the bending piece, so that the damping disk 6026 inside the limit cylinder 601 is separated from the guide rail 40; then the limit cylinder 601 is moved to the position of the angle mark that needs to be bent and stops, and the limit cylinder 601 is moved. The limit cylinder 601 can only slide along the guide rail 40 under the dual limit of the ball 604 and the guide rail 40, and will not turn over, and the ball 604 will roll against the scale plate 30; when the limit cylinder 601 reaches the specified scale line position, the pressing rod 6022 is pressed, and the state of the locking assembly 602 changes from Figure 5 The state A in the figure changes to the state D through the states B and C. At this time, the rebound rod 6024 drives the damping disc 6026 upward into the relatively shallow slot of the slot cylinder 6023 under the action of the spring 6025; the rebound rod 6024 moves a distance away from the pressing rod 6022 compared to the state A, thereby driving the damping disc 6026 to press the guide rail 40; at this time, when the operator bends the bending piece, the bending arm 10 stops bending immediately when it hits the limit cylinder 601. Finally, the precise bending angle of the bending piece is controlled, thereby effectively solving the problem that the bending accuracy of the existing bending machine cannot be precisely controlled.
