Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a split sheet metal stamping die. Background Technology

[0002] In the past, manufacturing U-shaped bending brackets required bending the sheet metal material. Due to equipment limitations, manual bending was typically used, but this was extremely difficult, time-consuming, and labor-intensive, resulting in poor bending quality. With societal development and technological advancements, bending can now be achieved using stamping dies. This dies reduce the difficulty and save time and labor. However, older stamping dies were relatively simple, easily causing sheet metal breakage during the stamping process, and were only suitable for small-batch production. For large-scale production, both stamping quality and efficiency could not be guaranteed.

[0003] Chinese patent CN204262192U discloses a sheet metal stamping die, including an upper die plate, a lower die plate, a guide post device, a punch and a die assembly. Although the punch and die assembly can process the raw sheet metal and ensure that the raw sheet metal is not easily broken during processing, this sheet metal stamping die can only process raw sheet metal of the same specification and cannot meet the needs of processing raw sheet metal of different specifications. Therefore, we propose a split sheet metal stamping die. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a split sheet metal stamping die that can process sheet metal of different specifications, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a split sheet metal stamping die, including a support frame and stamping components;

[0006] Support frame: A support frame is fixed on the lower side, and a limit component is installed on the side of the support frame;

[0007] The stamping assembly includes a hydraulic rod, a connecting box, a locking block, a locking hole, a locking rod, a connecting plate, a spring, and a U-shaped stamping frame. The upper side of the support frame has a mounting hole, inside which a hydraulic rod is installed. A connecting box is fixed to the telescopic arm of the hydraulic rod. A locking block is located inside the connecting box, with a locking hole in the center of the locking block. Two corresponding sliding holes are located on the left and right sides of the connecting box, with a locking rod slidably connected inside each sliding hole. A connecting plate is fixed to the end face of the locking rod outside the connecting box. A spring is fitted onto the circumference of the locking rod, with one end fixed to the end face of the connecting plate and the other end fixed to the side of the connecting box. A stamping frame is fixed to the lower side of the locking block. The hydraulic rod is controlled by an external control switch group. The stamping assembly is used to stamp sheet metal materials.

[0008] Furthermore, the limiting assembly includes a first motor, a limiting frame, a bidirectional screw, and a limiting rod. The first motor is installed on the right side of the support frame. Two limiting frames are provided, each with a threaded hole on its rear side. The threads of the two threaded holes are opposite, and the internal threads of the two threaded holes are connected to a bidirectional screw. The bidirectional screw is welded together from two threaded rods with opposite threads. The bidirectional screw is rotatably connected to the rear end inside the support frame. The front side of the limiting frame has a limiting hole, and the internal threads of the two limiting holes are slidably connected to a limiting rod. The limiting rod is fixed to the front end inside the support frame. The output shaft of the first motor is fixed to the right end of the bidirectional screw. The input end of the first motor is electrically connected to the output end of an external control switch group. The limiting assembly is used to limit the sheet metal material.

[0009] Furthermore, it also includes a pressing assembly, which comprises a second motor, an L-shaped connecting strip, a pressing rod, and a guide rod. Two corresponding grooves are formed on the front and rear sides of the limiting frame, and the L-shaped connecting strip is rotatably connected inside the grooves. Two corresponding second motors are mounted on the side of the limiting frame, and the output shafts of the second motors are fixed to the side of the L-shaped connecting strip. The pressing rod is rotatably connected to the side of the L-shaped connecting strip. A connecting groove is formed on the upper side of the limiting frame, and the guide rod is rotatably connected inside the connecting groove. The input end of the second motor is electrically connected to the output end of an external control switch group. The pressing assembly is used to press sheet metal materials.

[0010] Furthermore, two corresponding limiting strips are fixed on the upper side of the support frame, and a measuring ruler is fixed on the upper side of the front limiting strip. The measuring ruler allows the user to easily determine the position of the two limiting frames.

[0011] Furthermore, four corresponding support legs are fixed to the lower side of the support frame, and a base is fixed to the lower end of each support leg. The support frame is supported by the support legs and the base.

[0012] This invention, by setting a limiting component, allows the first motor to be started during use to rotate the bidirectional screw as needed. The rotation of the bidirectional screw drives the two limiting frames to move. When the two limiting frames move to the appropriate position, the first motor is turned off. Then, the stamping material is placed above the two guide rods, and the two clamping rods are pulled to separate from the clamping holes. After separation, the clamping blocks are removed, and a U-shaped stamping frame of appropriate size is installed. Then, the hydraulic rod is started to move the U-shaped stamping frame downward, which can stamp sheet metal of different specifications, making it extremely convenient. Attached Figure Description

After fitting, the two clamping rods 35 are pulled to separate from the clamping holes 34. After separation, the clamping blocks 33 are removed, and a U-shaped stamping frame 38 of appropriate size is installed. Then, the hydraulic rod 31 is activated, causing the U-shaped stamping frame 38 to move downward, thus stamping sheet metal of different specifications, which is extremely convenient.
