Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die with adjustable direction. Background Art

[0002] A stamping die refers to a process equipment that processes the workpiece into a finished product or semi-finished product in the stamping process. Its main power comes from other top-down stamping forms such as hydraulic cylinders or air cylinders, and then uses this power to stamp the workpiece to separate or plastically deform it, thereby obtaining the desired finished product or semi-finished product. However, most of the stamping dies that exist and are used at this stage are found to require some parts to be stamped at a certain angle in order to meet the expected production needs. The traditional adjustment method is mostly to remove the die and then install the die at an angle to meet the stamping requirements. This method requires the die to be constantly disassembled and adjusted, which greatly reduces work efficiency.

[0003] Therefore, it is necessary to provide a new stamping die with adjustable direction to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a stamping die with adjustable direction.

[0005] The direction-adjustable stamping die provided by the utility model comprises a base, on which two groups of symmetrically distributed brackets are installed, and the two groups of brackets are provided with semicircular rotating columns that are rotatably connected;

[0006] Half gear rings are fixedly embedded on the outer walls of both sides of the semicircular rotating column, and a servo motor for driving the semicircular rotating column to rotate is installed between the two groups of the brackets;

[0007] The bracket is provided with a micro hydraulic cylinder for pressing the side wall of the semicircular rotating column;

[0008] A mold is installed on the semicircular rotating column.

[0009] Preferably, the servo motor is fixedly mounted on the bracket via a frame, and a rotating shaft is fixedly mounted on the output end of the servo motor, two fixedly connected gears are mounted on the rotating shaft, and the two gears are respectively meshed and connected with the half gear rings on both sides of the semicircular rotating column.

[0010] Preferably, a semicircular pressing groove is provided on the side wall of the semicircular rotating column, and the semicircular pressing groove corresponds to the output end of the micro hydraulic cylinder.

[0011] Preferably, a mounting hole is provided on the semicircular rotating column.

[0012] Preferably, a support column is fixedly installed at the bottom of the mold, and a mounting seat is fixedly installed at the bottom of the support column, and fixing holes are opened at the corners of the mounting seat.

[0013] Preferably, the mounting seat is fixedly connected to the mounting hole on the semicircular rotating column by means of screws passing through the fixing hole.

[0014] Compared with the related art, the direction-adjustable stamping die provided by the utility model has the following beneficial effects:

[0015] The utility model turns on the servo motor to drive the two gears on the rotating shaft to rotate. Since the two gears are respectively meshed and connected with the half gear rings on both sides of the semicircular rotating column, the angle of the mold can be changed by the servo motor. After adjusting to the specified angle, the servo motor is turned off, and the stamping angle of the mold can be quickly adjusted. Compared with the traditional disassembly and re-installation, this method is faster. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] See also Figures 1 to 4An embodiment of the utility model provides a stamping die with adjustable direction, and the stamping die with adjustable direction includes: a base 1, a semicircular rotating column 3 and a die 7.

[0024] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , two groups of symmetrically distributed brackets 2 are installed on the base 1, and the two groups of brackets 2 are provided with rotatably connected semicircular rotating columns 3, and the outer walls on both sides of the semicircular rotating columns 3 are fixedly embedded with half gear rings 31, and a servo motor 4 for driving the semicircular rotating columns 3 to rotate is installed between the two groups of brackets 2, and the servo motor 4 is fixedly installed on the bracket 2 through a frame, and a rotating shaft 41 is fixedly installed on the output end of the servo motor 4, and two fixedly connected gears 5 are installed on the rotating shaft 41, and the two gears 5 are respectively meshed with the half gear rings 31 on both sides of the semicircular rotating columns 3;

[0025] A mold 7 is installed on the semicircular rotating column 3, and a mounting hole 3a is opened on the semicircular rotating column 3, and a support column 71 is fixedly installed on the bottom of the mold 7, and a mounting seat 72 is fixedly installed on the bottom of the support column 71, and a fixing hole 72a is opened at the corner of the mounting seat 72, and the mounting seat 72 is fixedly connected to the mounting hole 3a on the semicircular rotating column 3 by screws passing through the fixing hole 72a;

[0026] The bracket 2 is provided with a micro hydraulic cylinder 6 for pressing the side wall of the semicircular rotating column 3 , and the side wall of the semicircular rotating column 3 is provided with a semicircular pressing groove 3 b , and the semicircular pressing groove 3 b corresponds to the output end of the micro hydraulic cylinder 6 .

[0027] It should be noted that: after the mold 7 is fixed on the semicircular rotating column 3 by screws, the device is first fixed at the designated stamping position (that is, the mold 7 is located below the stamping upper mold), so that the mold 7 corresponds to the external upper mold up and down. When stamping in a parallel state, the workpiece to be processed is placed on the mold 7, and then the external upper mold is pressed down to perform stamping and forming work;

[0028] At a later stage, if the stamping angle of the die 7 needs to be adjusted according to processing requirements, the servo motor 4 is turned on to drive the two gears 5 on the rotating shaft 41 to rotate. Since the two gears 5 are respectively meshed and connected with the half gear rings 31 on both sides of the semicircular rotating column 3, the angle of the die 7 can be changed by the servo motor 4. After the servo motor 4 is turned off after adjusting to the specified angle, the stamping angle of the die 7 can be quickly adjusted. Compared with the traditional disassembly and re-installation, this method is faster.

[0029] Subsequently, the micro hydraulic cylinders 6 on both sides are opened so that the output ends of the micro hydraulic cylinders 6 are pressed against the semicircular pressing grooves 3b on the side walls of the semicircular rotating column 3, thereby enhancing the stability of the semicircular rotating column 3 after being adjusted to a specified angle;

[0030] In the present embodiment: In order to ensure that the servo motor 4 can remain in a specific position when it stops in the present device, this can be achieved by adding self-locking logic in the control algorithm. For example, when the servo motor 4 stops, the controller can continuously output a small torque to keep the servo motor 4 in the current position, thereby preventing position deviation due to external force or other factors. This is a prior art and will not be elaborated here.

[0031] The working principle of the stamping die with adjustable direction provided by the utility model is as follows:

[0032] After fixing the mold 7 on the semicircular rotating column 3 with screws, the device is first fixed at the specified stamping position (that is, the mold 7 is located below the stamping upper mold), so that the mold 7 corresponds to the external upper mold up and down. When stamping in a parallel state, the workpiece to be processed is placed on the mold 7, and then the external upper mold is pressed down to perform stamping and forming work on it; in the later stage, if it is necessary to adjust the stamping angle of the mold 7 according to the processing requirements, the servo motor 4 is turned on to drive the two gears 5 on the rotating shaft 41 to rotate. Since the two gears 5 are respectively meshed and connected with the half gear rings 31 on both sides of the semicircular rotating column 3, the angle of the mold 7 can be changed by the servo motor 4. After the servo motor 4 is turned off after adjusting to the specified angle, the stamping angle of the mold 7 can be quickly adjusted. Compared with the traditional disassembly and re-installation, this method is faster. Subsequently, the micro hydraulic cylinders 6 on both sides are turned on so that the output ends of the micro hydraulic cylinders 6 are abutted against the semicircular pressing grooves 3b on the side walls of the semicircular rotating column 3, thereby enhancing the stability of the semicircular rotating column 3 after being adjusted to the specified angle.

[0033] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0034] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
