Description

Technical Field

[0001] This utility model relates to the field of stainless steel sheet processing technology, specifically to a bending device for stainless steel sheets. Background Technology

[0002] Stainless steel sheet is a very common and important metal material. It is widely used in various fields due to its excellent corrosion resistance, good mechanical properties and beautiful surface. Stainless steel sheet refers to flat steel made of stainless steel. Its core characteristic of rust resistance comes from the addition of a high proportion of chromium to the steel. After chromium reacts with oxygen, it forms a very thin and dense chromium oxide film on the surface. This film can prevent the iron elements inside from being further oxidized, thus achieving rust resistance and corrosion resistance. Stainless steel sheet bending equipment is a kind of machine specially used for cold bending and forming stainless steel sheets. It applies huge force to make the sheet plastically deform at a predetermined position, thereby obtaining a workpiece with the required angle and shape. In some existing stainless steel sheet bending equipment, when bending stainless steel sheets, the stainless steel sheet is first placed on the equipment worktable and pressed against the back gauge and other positioning structures. The solenoid valve is triggered by the control switch, and compressed air enters the cylinder, pushing the cylinder piston rod to extend, which drives the gripper or pressure plate to move towards the sheet until the sheet is pressed tightly. After the sheet is clamped in place, the hydraulic rod operates, and the extension end of the hydraulic rod will drive the pressure bar to bend the stainless steel sheet. Existing stainless steel sheet bending equipment has the following problems: when bending stainless steel sheets, it relies on compressed air pressure to fix the stainless steel sheets. Air pressure fluctuations will directly affect the uniformity of clamping force, resulting in poor bending effect of stainless steel sheets. To address this, we propose a stainless steel sheet bending equipment. Utility Model Content

When bending stainless steel sheets, the device uses a simple mechanical structure to fix the stainless steel sheets, resulting in more uniform clamping and better bending effect. This effectively solves the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a bending device for stainless steel plates, including a machine base, a support at the upper end of the machine base, guide rods slidably connected inside the sliding holes at the upper end of the support, a pressing rod fixedly connected between the lower ends of the two guide rods, left and right symmetrical guide rails at the upper end of the machine base, a support platform slidably connected between the two guide rails, and a clamping mechanism.

A rotating shaft is rotatably connected between the two vertical plates. The first bevel gear is fixedly connected to the left and right ends of the rotating shaft. The second bevel gear is fixedly sleeved on the outer surface of the internal threaded ring. The first bevel gear meshes with the vertically adjacent second bevel gear to provide a transmission connection.

[0007] Furthermore, the drive assembly also includes a worm, a worm wheel, and a motor. The worm is rotatably connected between the upper and lower inner walls of the protective cover. The worm wheel is fixedly sleeved in the middle of the rotating shaft, and the worm and the worm wheel are meshed together. The protective cover is equipped with a motor.

The front end of the output shaft of the second motor is fixedly connected to the rear end of the threaded rod, and the input end of the second motor is electrically connected to the output end of the control switch group to provide rotation drive.

[0010] Furthermore, the upper end of the bracket is provided with a hydraulic rod, the telescopic end of which is fixedly connected to the middle part of the upper end of the pressure rod to provide downward driving.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This stainless steel sheet bending equipment has the following advantages: Driven by motor one, the rotating shaft is driven by the worm gear and meshing worm wheel to rotate the bevel gears on both sides. The bevel gear one, through the meshing bevel gear two, causes the internal threaded ring inside the cylinder to drive the threaded screw upward.

When bending the stainless steel sheet, the stainless steel sheet is fixed by a simple mechanical structure, and the clamping of the stainless steel sheet is more uniform, ensuring a better bending effect.

The drive assembly 88 also includes a worm 886, a worm wheel 887, and a motor 888. The worm 886 is rotatably connected between the upper and lower inner walls of the protective cover 881. The worm wheel 887 is fixedly fitted in the middle of the rotating shaft 883. The worm 886 meshes with the worm wheel 887. The protective cover 881 is equipped with a motor 888. The lower end of the output shaft of the motor 888 is fixedly connected to the upper end of the worm 886. The input end of the motor 888 is electrically connected to the output end of the control switch group 12. When bending the stainless steel sheet, the stainless steel sheet is first inserted between the upper end of the support platform 7 and the lower end of the pressure plate 82, so that it does not... The rear end of the stainless steel plate is aligned with the rear end of the support platform 7. Then, the pressure plate 82 is gently lifted upwards. (Allowance holes corresponding to the screw 85 are provided on the left and right sides of the front end of the support platform 7 to prevent the screw 85 from being rubbed when the pressure plate 82 is lifted.) The pressure plate 82 will drive the screw 85 and the clamping plate 87 to insert into the clamping slot 86. Then, by controlling the control switch group 12, the motor 888 will operate. The output shaft of the motor 888 will drive the worm 886 to rotate. The rotation of the worm 886 will drive the meshing worm wheel 887 to rotate. The rotation of the worm wheel 887 will drive the rotating shaft 883 to rotate. The rotation of the rotating shaft 883 will drive the bevel gear 884 to rotate. The bevel gear 884 will drive the internal threaded ring 84 to rotate inside the cylindrical cylinder 83 through the meshing bevel gear 885.The rotation of the internal threaded ring 84 will cause the threaded screw 85 to move upward, which in turn will pull the clamping plate 87 upward, making the clamping plate 87 fit tightly against the clamping groove 86, thereby clamping the stainless steel sheet between the support platform 7 and the pressure plate 82.

[0016] The working principle of the stainless steel sheet bending device provided by this utility model is as follows: When bending the stainless steel sheet, first insert the stainless steel sheet between the upper end of the support platform 7 and the lower end of the pressure plate 82, aligning the rear end of the stainless steel sheet with the rear end of the support platform 7. Then, gently lift the pressure plate 82 upwards, causing the screw 85 and the clamping plate 87 to insert into the clamping slot 86. Next, by controlling the control switch group 12, the motor 888 operates, and the output shaft of the motor 888 drives the worm gear 886 to rotate. The rotation of the worm gear 886 drives the meshing worm wheel 887 to rotate, which in turn drives the rotating shaft 883 to rotate. The rotation of the rotating shaft 883 drives the bevel gear 884 to rotate, which in turn drives the internal thread ring 84 to rotate inside the cylindrical cylinder 83 through the meshing bevel gear 885. The rotation of the internal thread ring 84 will... The screw 85, driven by the thread, moves upward, which in turn pulls the clamping plate 87 upward, making the clamping plate 87 fit tightly against the clamping groove 86. This causes the support platform 7 and the pressure plate 82 to clamp the stainless steel sheet. Then, by controlling the control switch group 12, the motor 11 operates. The output shaft of the motor 11 drives the threaded rod 9 to rotate. The rotation of the threaded rod 9 causes the support platform 7 to move forward between the two guide rails 6 through the threaded slider 10, thus moving the stainless steel sheet forward. The worker can visually observe that the front end of the stainless steel sheet is aligned with the front end of the machine platform 1. Then, the stainless steel sheet is moved to the lower end of the lower pressure rod 4. Next, hydraulic oil is supplied to the hydraulic rod 5 by an external hydraulic pump, which causes the extension rod of the hydraulic rod 5 to move downward. This causes the lower pressure rod 4 to bend the stainless steel sheet under the guidance of the guide rod 3.

[0017] It is worth noting that the motor 888 and motor 11 disclosed in the above embodiments can both be YS8024. The control switch group 12 is provided with a switch button that corresponds one-to-one with motor 888 and motor 11 and is used to control their switching operation.
