Description

Technical Field

[0001] This utility model mainly relates to the field of stamping die technology, specifically to a stamping die with a switchable stamping head. Background Technology

[0002] Stamping dies are key equipment in the metal processing industry, widely used in the automotive, electronics, and home appliance industries. They are used to perform blanking, forming, and stretching processes on sheet metal or workpieces using a stamping head. Traditional stamping dies typically employ a structure with a single stamping head and a lower die, designed for specific workpiece shapes and sizes. When processing different workpieces, operators must disassemble the original stamping head according to process requirements, replace it with a suitable one, and re-secure it using bolts or clamps. This process not only relies on manual operation but also requires repeated adjustments using tools such as wrenches and fixtures, resulting in long production downtime and low efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0026] See attached document Figure 1-4A stamping die with a switchable stamping head includes a base 1 and a die clamp 2 fixedly installed on its top. An L-shaped gantry bracket 3 is also fixedly installed on the top of the base 1. A lifting cylinder 4 is provided on the top plate of the L-shaped gantry bracket 3. The piston rod of the lifting cylinder 4 vertically penetrates the top plate of the L-shaped gantry bracket 3 and is fixedly connected to the lifting drive plate 5.

[0027] The top of the lifting drive plate 5 is equipped with a servo drive motor 6. The servo drive motor 6 rotates 90° each time through the PLC control system. Its output shaft passes vertically through the lifting drive plate 5 and is connected to a rotating mounting plate 7. Four telescopic mechanisms 9 are arranged at equal angles along the circumference inside the rotating mounting plate 7. The bottom of each telescopic mechanism 9 extends to the bottom of the rotating mounting plate 7 and is equipped with a stamping head 8 of different specifications.

[0028] In this embodiment, after the workpiece to be stamped is positioned by the mold fixture 2, the lifting cylinder 4 is activated to drive the lifting drive plate 5 to descend. The stamping head 8 mounted on the rotating mounting plate 7 and the telescopic mechanism 9 descends synchronously, so that the workpiece can be stamped. After the servo drive motor 6 rotates 90° through the PLC control system, the rotating mounting plate 7 and the telescopic mechanism 9 rotate synchronously, so that another stamping head 8 of a different specification can be rotated to be directly above the workpiece. Thus, it is possible to quickly switch between stamping heads 8 of different specifications without disassembling and replacing the stamping head 8, so as to realize stamping processing for different needs and greatly improve production efficiency.

[0029] It should be noted that the servo drive motor 6 rotating 90° through the PLC control system is existing public technology and common knowledge, so it will not be described in detail here.

[0030] The top of the lifting drive plate 5 is provided with two locking cylinders 10 symmetrically distributed about the axis of the servo drive motor 6. The piston rod of the locking cylinder 10 penetrates vertically through the lifting drive plate 5. The top of the rotating mounting plate 7 is provided with four locking holes 71 arranged at equal angles in the circumference. The tangent direction of its rotation trajectory coincides with the projection of the axis of the piston rod of the locking cylinder 10.

[0031] In this embodiment, when the servo drive motor 6 switches the stamping head 8 of different specifications to the stamping station, the piston rod of the locking cylinder 10 can be inserted into the locking hole 71 after the cylinder is started, thereby locking it to prevent shaking.

[0032] The telescopic mechanism 9 includes a movable column 91, which is slidably connected to a first slide groove 72 at the bottom of the rotating mounting plate 7. The top of the first slide groove 72 is connected to a second slide groove 73 extending to the top of the plate. The bottom of the movable column 91 passes through the first slide groove 72 and is fixed to the mounting plate 92. The punch head 8 is located at the bottom of the mounting plate 92. The top of the movable column 91 extends into the second slide groove 73 and is fitted with a limit screw 93. The limit screw 93 is movably installed in the second slide groove 73. A spring 94 is sleeved on the movable column 91. The spring 94 is located between the limit screw 93 and the bottom of the second slide groove 73 and is used to drive the movable column 91 to rise.

[0033] The top of the lifting drive plate 5 is provided with a push cylinder 11. The piston rod of the push cylinder 11 penetrates vertically through the lifting drive plate 5, and the projection of its axis coincides with the tangent direction of the rotation trajectory of the limit screw 93.

[0034] In this embodiment, when the stamping head 8 is located at the stamping station, the push cylinder 11 activates the push limit screw 93 and compresses the spring 94, so that the movable column 91 slides downward in the first slide groove 72, and the stamping head 8 descends synchronously with the mounting plate 92. After the push cylinder 11 is closed, the stamping head 8 can be restored to its original height by the elastic force of the spring 94.

[0035] The top of the lifting drive plate 5 is provided with a maintenance groove 51, and the maintenance groove 51 and the push cylinder 11 are symmetrically distributed about the axis of the servo drive motor 6.

[0036] In this embodiment, the servo drive motor 6 drives the rotating mounting plate 7 to rotate. When the limit screw 93 is aligned with the maintenance groove 51, the operator can use a screwdriver to remove the limit screw 93 and replace the spring 94.

[0037] Vertical guide rods 12 are provided at the four corners of the top of the lifting drive plate 5. The guide rods 12 are slidably connected to the top plate of the L-shaped gantry bracket 3 to improve the stability of the lifting drive plate 5 when it is raised or lowered.

[0038] The L-shaped gantry support 3 is provided with multiple evenly distributed triangular support frames 13 at its support points to improve the support stability of the L-shaped gantry support 3.

[0039] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0040] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art.
