Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, and more specifically, it relates to a multi-angle hard disk metal casing bending machine. Background Technology

[0002] In the manufacturing process of hard drives, bending machines are often used to apply external force to plastically deform metal sheets, thereby processing flat sheets into the specific three-dimensional structure required for the hard drive casing. In the actual application of bending machines, operators need to support the casing to ensure smooth operation and product quality during the bending process of the metal casing.

[0003] For example, existing application number CN202321623191.8 relates to a bending machine for processing lithium battery metal casings, including a frame, a bending head, and a bending seat. Pneumatic cylinders are symmetrically installed inside the frame, and a support shaft is also installed inside the frame. The telescopic end of each pneumatic cylinder is rotatably connected to one end of an adjusting arm mounted on the support shaft via a connecting arm. The other end of the adjusting arm is rotatably connected to the top end of a connecting rod, and the bottom end of the connecting rod is rotatably connected to an ear seat. Both ear seats are connected to the bending head. A bending seat adapted to the bending head is installed on the frame. A motor drives the rotating shaft to rotate. At this time, the rotating teeth on the shaft rotate and engage with a meshing rack, causing the slide to move. This adjusts the position of the limiting block on the slide plate. The adjusted limiting block blocks block and limit the lithium battery metal casing material to be processed, allowing for direct bending operations and improving work efficiency.

[0004] Based on the above, when bending the hard drive casing, the metal sheet is easily displaced under the pressure of the mold due to uneven manual support during the process of applying pressure to the metal sheet. This results in the side bending and warping of the casing after bending, which can cause the edge of the warped edge to interfere with the hard drive body, circuits or interfaces during subsequent assembly. This not only makes assembly difficult, but also easily causes abnormal noise and malfunctions during hard drive operation, and damages internal precision components. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a multi-angle hard drive metal casing bending machine. This machine solves the problem that during the bending process, uneven manual support can easily cause the metal sheet to shift under the mold pressure, resulting in side bending and warping of the casing after bending. This warping can lead to interference between the edge of the warped edge and the hard drive's platter, wiring, or interface during subsequent assembly. This not only makes assembly difficult but also easily causes abnormal noises and malfunctions during hard drive operation, and damages internal precision components.

[0006] The purpose and effect of this utility model, a multi-angle hard drive metal casing bending machine, are achieved by the following specific technical means: A multi-angle hard drive metal casing bending machine includes a support operating table, bending auxiliary frames, limiting brackets, pressure guides, movable support plates, and positioning auxiliary mechanisms. The bending auxiliary frames are inserted into the outer side of the top end face of the support operating table. Bending auxiliary grooves are evenly arranged on the inner side of the bending auxiliary frames, each groove having a different diameter. Two limiting brackets are symmetrically fixed to the top end face of the support operating table. The pressure guides slide vertically between the two bending auxiliary frames. The positioning auxiliary mechanism is located outside the pressure guides. The movable support plate slides forward and backward on the upper side of the rear end face of the bending auxiliary frames. The positioning auxiliary mechanism includes a positioning bracket located on the outer side of the upper end of the support operating table. An electric suction cup is rotatably mounted on the top end face of the positioning bracket.

[0007] Furthermore, a drive support shaft is rotatably provided at the front end of the pressure guide; both ends of the drive support shaft are rotatably connected to the limiting bracket, and the outer end of the drive support shaft is coaxially fixedly connected to the outside of the drive motor shaft; a bending bracket is installed on the outer side of the bottom end face of the pressure guide using multiple positioning studs.

[0008] Furthermore, a limiting guide is fixedly connected to the outer side of both ends of the pressure guide; the limiting guide is a T-shaped frame structure, and the pressure guide is slidably connected to the limiting bracket; a drive rack is fixedly connected to the outer side of the front end face of the limiting guide; drive gears are coaxially fixedly connected to both ends of the drive shaft; the drive gears on the left and right sides mesh with the drive rack.

[0009] Furthermore, the outer side of the movable support plate is connected to a second electric actuator via an L-shaped connecting bracket; the L-shaped connecting bracket is fixedly connected to the piston rod of the second electric actuator; the outer end of the second electric actuator is fixedly connected to the support operating table.

[0010] Furthermore, the positioning auxiliary mechanism includes: a transmission shaft and a transmission rack, the transmission shaft being rotatably connected to the inner end of the supporting operating table; transmission gears being coaxially and fixedly connected to the left and right ends of the transmission shaft; there are two transmission racks, each fixedly connected to the outer side of the bottom end face of the limiting bracket; the transmission racks on the same side mesh with the transmission gears; spiral springs are fixedly connected between the left and right sides of the transmission shaft and the supporting operating table; a first electric push rod is fixedly connected to the outer end of the transmission shaft; a piston rod is slidably connected to the outer end of the first electric push rod; and the piston rod is fixedly connected to the positioning bracket.

[0011] Furthermore, the positioning auxiliary mechanism also includes a driving worm and a driving worm wheel. The driving worm is rotatably connected to the inner end of the positioning bracket, and the outer end of the driving worm is coaxially fixed to the outer side of the transmission motor shaft. The driving worm wheel is vertically rotatably disposed on the outer side of the driving worm, and the driving worm and the driving worm wheel mesh with each other.

[0012] Furthermore, a drive auxiliary wheel is coaxially and fixedly connected to the top end face of the drive worm gear; an eccentric drive column is fixedly connected to the outer side of the drive auxiliary wheel; a drive groove wheel is rotatably provided on the outer side of the drive auxiliary wheel, and the drive groove wheel is coaxially and fixedly connected to the bottom end face of the positioning bracket.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention employs a movable support plate to provide stable support to the rear end face of the metal sheet during use, preventing the rear end of the sheet from wobbling during bending. The electric suction cup in the positioning auxiliary mechanism firmly adheres to the sheet surface. Combined with the linkage between the transmission shaft and the transmission rack, when the pressure guide is applied for bending, it drives the positioning bracket and the sheet to rotate inward synchronously, achieving follow-up positioning. This not only avoids the impact of uneven manual support and reduces the displacement of the sheet under pressure, but also prevents side bending and warping of the outer shell after bending. This prevents interference between the warped edge and the hard drive body, circuitry, or interface during subsequent assembly, reducing the risk of abnormal noise and malfunctions caused by component friction during hard drive operation, and protecting internal precision components. In use, this utility model employs a positioning auxiliary mechanism with a drive worm gear meshing with a drive worm wheel, and in conjunction with the linkage between the eccentric drive column and the drive groove wheel, drives the electric suction cup and the adsorbed plate to flexibly adjust the angle, thereby realizing bending operations on multiple sides of the plate and further improving the bending efficiency of metal plates. This invention requires no manual support or adjustment during use, which not only reduces the labor intensity of operators but also avoids individual differences caused by manual operation, ensuring that the parameters of each bending process remain consistent, thus ensuring the stability of product quality in mass production and reducing the scrap rate caused by human error.
