Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal forming and bending machines, specifically a sheet metal forming and bending machine. Background Technology

[0002] The original process required two stations to complete the operation. The specific steps were as follows: First, the sheet metal was fed to the forming machine station. Then, the forming mold of the forming machine was used to imprint the sheet metal. Next, the sheet metal was removed from the forming machine station and entered the end-folding station. At this time, the sheet metal with imprints was flipped and bent through the end-folding station. Finally, the sheet metal was removed from the end-folding station and entered the next station.

[0003] While the above process can achieve the effect of sheet metal and sheet production, the large footprint of the equipment reduces the space utilization rate of the equipment and increases the power consumption of the equipment, thereby increasing the operating cost of the existing equipment. At the same time, the process is relatively complex and reduces production efficiency. Therefore, we propose a sheet metal forming and bending machine. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This sheet metal forming and bending machine, through its upper forming die, flipping die strip, forming cylinder, pressing arm, and worktable, allows the user to transport the sheet metal to the worktable via a conveying system. The pressing cylinder then operates, clamping the sheet metal with the pressing die strip to ensure its stability. Subsequently, the upper forming die extends through the output shaft of the forming cylinder to perform groove pressing on the sheet metal. Combined with the operation of the flipping die strip and the end bending cylinder, the pressed sheet metal is bent, achieving the effect of pressing and bending the sheet metal sequentially.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 A sheet metal forming and bending machine includes an upper forming die 1, a workbench 9 on the outer wall of the upper forming die 1, a workbench 10 fixedly mounted on the top of the workbench 10, a forming cylinder 6 fixedly mounted on the top of the workbench 10, the output shaft of the forming cylinder 6 fixedly mounted to the upper forming die 1, an end bending cylinder 5 and a pressing cylinder 7 respectively on the inner and outer walls of the workbench 19, a flipping die strip 2 fixedly mounted on the output shaft of the end bending cylinder 5, a lower die strip 4 fixedly mounted on the top of the workbench 19, a pressing arm 8 rotatably connected to the output shaft of the pressing cylinder 7, and a pressing die strip 3 fixedly mounted on the end of the pressing arm 8 away from the pressing cylinder 7.

[0023] In the above structure, the upper pressing die 1, the flipping die strip 2, the pressing die strip 3, the lower die strip 4, the end bending cylinder 5, the pressing oil cylinder 6, and the pressing cylinder 7 enable the bending machine to perform both pressing and bending functions compared to existing bending machines. This reduces the amount of equipment required for the bending machine, thereby reducing energy consumption and operating costs, and ultimately improving its practicality and application value.

[0024] In a preferred embodiment, the outer wall of the pressure arm 8 is rotatably connected to the inner wall of the worktable 10, and the pressure arm 8 is made of galvanized iron.

[0025] In the above structure, galvanized iron has the characteristics of hardness and wear resistance, which can ensure that the pressure arm 8 can drive the pressure die 3 to descend and clamp the sheet when rotating, thereby ensuring that the sheet will not tilt or even shift in position during the pressing process, improving the processing accuracy of the bending machine on the sheet. The rotation of the pressure arm 8 can achieve the effect of automatically fixing the sheet, thereby improving the automation and functionality of the bending machine.

[0026] In a preferred embodiment: the bottom of the upper pressing mold 1 is provided with a groove, and the top of the flipping mold strip 2 is provided with a triangular protrusion, and the position of the triangular protrusion corresponds to the position of the groove.

[0027] In the above structure, the groove and triangular protrusion structure enable the bending machine to press down the upper die 1 and lift the sheet material through the flipping die 2 during operation, thereby forming a groove at the end of the sheet material and achieving the effect of pressing the sheet material, thus ensuring the normal use of the bending machine.

[0028] In a preferred embodiment: a mounting base is fixedly mounted on the outer wall of the workbench 9, and a rotating plate is rotatably connected to the inner wall of the mounting base; the outer wall of the pressing cylinder 7 is fixedly mounted to the middle of the rotating plate.

[0029] In the above structure, through the installation base and rotating plate structure, during operation, the user can drive the rotating plate to rotate via the motor, thereby adjusting the angle of the pressing arm 8 in conjunction with the extension and retraction of the output shaft of the pressing cylinder 7, so as to achieve the effect of precisely clamping the material sheet, and thus realize the function of automated pressing and bending of the material sheet.

[0030] In a preferred embodiment, there are two end bending cylinders 5 and two pressing cylinders 7, and the two end bending cylinders 5 and the two pressing cylinders 7 are symmetrically distributed along the outer wall of the worktable 9.

[0031] In the above structure, the two end bending cylinders 5 can be used to make the flipping die 2 flip after lifting the material sheet, so that the pressed end of the material sheet can be bent. This achieves the effect of pressing and bending at the same time, thereby reducing the space occupied by the bending machine.

[0032] In a preferred embodiment, a sheet is placed between the pressing die 3 and the lower die 4, and the sheet is fixedly connected to the worktable 9 via the pressing die 3 and the lower die 4 respectively.

[0033] In the above structure, the material sheet can be clamped after being conveyed by the pressure die strip 3 and the lower die strip 4. This ensures that the vibration generated by the end bending cylinder 5, the forming cylinder 6, and the pressure cylinder 7 during operation will not affect the position of the material sheet. This allows the upper forming die 1 to accurately perform groove pressing on the end of the material sheet, thereby improving the precision fit and processing accuracy of the internal components in the bending machine.

[0034] Working principle: First, the user can transport the sheet metal to the workstation through the conveying system. After the sheet metal is in place, the pressing cylinder 7 drives the pressing arm 8 to rotate. As the angle of the pressing arm 8 changes, the pressing die 3 presses the sheet metal. At this time, the user can extend the output shaft of the forming cylinder 6 to make the upper forming die 1 press the end of the sheet metal, so that both the upper forming die 1 and the lower die 4 squeeze the sheet metal, thereby forming a groove at the end of the sheet metal. Then, the user can reset the upper forming die 1, and use the angle change of the pressing cylinder 7 and the extension and retraction of the output shaft to drive the flipping die 2 to flip, thereby achieving the bending effect at the end of the sheet metal. After the sheet metal is formed and bent, the pressing die 3 and the flipping die 2 will reset. The formed sheet metal is sent out of the workstation through the conveying system, thus achieving the effect of pressing and bending in sequence, reducing the space occupation of the bending machine and reducing the operating cost of the bending machine.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
