Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, and in particular to a metal sheet forming mold with an adjustable bending angle. Background Technology

[0002] Metal sheets refer to sheet materials that are processed from metal raw materials into extremely thin sheets with a large area through special processes. During the processing of metal sheets, it is necessary to test the mechanical properties of the metal material by bending. In order to meet different bending requirements, a metal sheet forming mold with an adjustable bending angle is used.

[0003] To address this, patent CN213559278U discloses a bending mold for metal sheets with adjustable bending angles. The mold includes an operating table with a clamping mechanism. The operating table has a swing groove, and a bending plate is oscillating within the swing groove via a rotating rod. A movable sleeve is fitted onto one end of the rotating rod extending outside the operating table, and a positioning rod is fixedly installed on the movable sleeve. A fastening nut is threaded onto the end of the rotating rod furthest from the operating table. A fixing block is fixedly installed on the side wall of the operating table, and the fixing block corresponds to the position of the positioning rod. The advantages are: this invention allows for adjustment and fixing of the bending plate's rotation angle as needed, enabling bending operations on metal sheets at different angles. It has a relatively wide range of applications, and the angle of the bent metal sheet is more precise, ensuring its effectiveness.

[0004] While the aforementioned adjustable bending die for metal sheets allows for bending operations at different angles, its inconvenience in limiting movement and guiding the metal sheet hinders its stability during use. Utility Model Content

[0005] The purpose of this invention is to provide a metal sheet forming mold with an adjustable bending angle, in order to solve the defect of existing metal sheet forming molds with adjustable bending angles being inconvenient for positioning.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a metal sheet forming mold with adjustable bending angle, including a worktable and a support;

[0007] The top of the workbench is fixed with a support, and the top of the support is provided with a movable structure.

[0008] An adjustment structure is fixed at the top of the workbench below the support;

[0009] A limiting structure is installed at the top of one side of the workbench. The limiting structure includes a limiting seat fixed to one side of the top of the workbench. A fixing plate is fixed to the other side of the top of the workbench. A first electric push rod passes through the top of the fixing plate. A movable seat is fixed to one end of the first electric push rod. A guide rod passes through the interior of the fixing plate below the first electric push rod. A first guide roller is rotatably connected to one side of the interior of the movable seat. A second guide roller is rotatably connected to one side of the top of the limiting seat.

[0010] When using this device, the setting of a limit structure enables the device to be guided easily, thereby improving the stability of the metal sheet forming mold during use; the setting of an adjustment structure enables the device to be adjusted easily to change the bending angle, thereby improving the applicability of the metal sheet forming mold during use; the setting of a moving structure enables the device to be bent easily, thereby improving the convenience of the metal sheet forming mold during use.

[0011] Preferably, the guide rod and the fixed plate form a sliding structure, and one end of the guide rod is fixedly connected to one side of the movable seat. Under the action of the first guide roller and the second guide roller, the metal sheet is guided. The guide rod enhances the stability of the movable seat during movement. The moved movable seat drives the first guide roller to move, thereby changing the distance between the first guide roller and the second guide roller, thus enabling the guidance of metal sheets of different widths.

[0012] Preferably, the adjustment structure includes a fixed frame, a threaded rod, a sliding rod, a bending seat, a servo motor, and a movable seat. The fixed frame is fixed to the top of the worktable below the support. A threaded rod is provided on the top of the fixed frame. A servo motor is installed on the outer wall of the fixed frame at one end of the threaded rod. Movable seats are threaded to the outer sides of both ends of the threaded rod. Sliding rods pass through both sides inside the movable seat. The top of the movable seat extends to the outside of the fixed frame and is fixed with a bending seat.

[0013] Preferably, the threads at both ends of the threaded rod are in opposite directions, and one end of the threaded rod extends to the outside of the fixed frame and is fixedly connected to the output end of the servo motor. By having the threads at both ends of the threaded rod in opposite directions, the threaded rod can drive the movable seats at both ends to move in opposite directions, which, under the action of the slide bar, enhances the stability of the movable seats during movement.

[0014] Preferably, the slide rod and the movable seat form a sliding structure, and both ends of the slide rod are fixedly connected to the inner wall of the fixed frame. After movement, the movable seat drives the bending seat to move, thereby changing the distance between the bending seats and thus changing the bending angle.

[0015] Preferably, the movable structure includes a second electric push rod, a lifting plate, a bending blade, and a sliding groove. The second electric push rod extends through the top of the support. Sliding grooves are provided on both sides of the top of the support, and a lifting plate is provided between adjacent sliding grooves. The bending blade is fixed to the bottom end of the lifting plate. The sliding grooves enhance the stability of the lifting plate during movement, and the moved lifting plate drives the bending blade to move up and down.

[0016] Preferably, the top end of the second electric push rod is fixedly connected to the bottom end of the lifting plate, and the lifting plate and the support form a sliding structure through a groove. Under the action of the bending seat, the bending blade bends the metal sheet.

[0017] The present invention provides a metal sheet forming mold with an adjustable bending angle, the advantages of which are:

[0018] By setting a limiting structure, the metal sheet is guided by the first guide roller and the second guide roller. The stability of the moving seat during movement is enhanced by the guide rod. The moving seat drives the first guide roller to move after movement, thereby changing the distance between the first guide roller and the second guide roller. This enables the guidance of metal sheets of different widths, realizing the guiding function of the device and improving the stability of the metal sheet forming mold during use.

[0019] By setting an adjustment structure, the threads at both ends of the threaded rod are opposite in direction, and the threaded rod can drive the movable seats at both ends to move in opposite directions. Under the action of the sliding rod, the stability of the movable seats during movement is enhanced. After the movement, the movable seats drive the bending seats to move, thereby changing the distance between the bending seats and thus changing the bending angle. This realizes the function of the device to easily adjust the bending angle, thereby improving the applicability of the metal sheet forming mold in use.

[0020] By incorporating a movable structure, the stability of the lifting plate during movement is enhanced by the action of the sliding groove. The moving lifting plate drives the bending knife to move up and down, and with the cooperation of the bending seat, the bending knife bends the metal sheet, thus realizing the function of easy bending of the device and improving the convenience of using the metal sheet forming mold.
