Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a high-strength plate split stamping die. Background Art

[0002] A split stamping die is a die used in stamping processes that is usually composed of multiple independent parts that can be installed, replaced or adjusted separately. Compared with a monolithic die, a split die has higher flexibility and customizability and can adapt to workpieces of different shapes, sizes or processing requirements.

[0003] After searching, the authorization announcement number CN219074135U discloses a split stamping die, including a bracket plate, a lower die is fixedly installed on the front surface of each slider, and a mounting groove is symmetrically opened on the upper surface of the bracket plate. A spring is fixedly installed on the lower surface of the inner cavity of each mounting groove, and the upper end of the spring is fixedly connected to a limit block, and the lower surfaces of the two limit blocks are jointly fixedly installed with a U-shaped rod that penetrates the bracket plate. The utility model controls the two limit blocks to limit the position of the lower die by pulling down the U-shaped rod and compressing the spring, and by starting the motor, the bidirectional screw connected to the output shaft is driven to rotate, so that the two sliders on the outside drive the lower die to move in opposite directions, so that the lower die is separated from the hardware, which solves the problem that the split stamping die in the prior art is usually a fixed structure, and the hardware of the electronic product after the stamping is completed will be stuck in the die due to deformation, resulting in difficulty in demolding, which reduces the efficiency of continuous stamping work.

[0004] The above technical solution facilitates demolding of formed electronic product hardware. When stamping a sheet, especially when stamping the sheet into an inwardly concave arc structure, the formed arc plate is inverted on the lower mold. The inverted arc plate is difficult to be unloaded quickly, which affects the stamping efficiency of the sheet.

[0005] To this end, we propose a high-strength plate split stamping die. Utility Model Content

[0006] The utility model mainly solves the above technical problems and provides a high-strength plate split stamping die.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-strength plate split stamping die, comprising a fixed base, a sliding lower die and a stamping upper die, the front and rear sides of the fixed base are fixedly installed with connecting plates, multiple groups of fixed rods are fixedly installed between the two groups of connecting plates, and the sliding lower die is slidably installed on the multiple groups of fixed rods;

[0008] The sliding lower die is provided with a workpiece positioning assembly for positioning the workpiece plate, the workpiece positioning assembly includes a plurality of fixed sleeves, the fixed sleeves are embedded and fixedly installed on the sliding lower die, a lifting shaft is slidably installed in the fixed sleeves, a reset spring is provided between the fixed sleeves and the lifting shaft, and a plurality of connecting grooves are provided on the bottom surface of the lifting shaft, and rollers are movably installed in the connecting grooves;

[0009] A long sliding groove is provided on the top surface of the fixed base at a position corresponding to the workpiece positioning component.

[0010] Preferably, the plurality of groups of fixed bushings are respectively distributed on the sliding lower die near the corners.

[0011] Preferably, the depths of the long sliding grooves are different, and when the lower sliding die slides back and forth on the fixed base, the plurality of groups of rollers will slide back and forth along the long sliding grooves.

[0013] Preferably, a connecting sleeve is fixedly mounted on the sliding lower die, and the sliding lower die is threadedly connected to the screw rod via the connecting sleeve.

[0014] Preferably, a mold protrusion is provided on the top surface of the sliding lower mold, and a plurality of groups of pull ears are provided on the stamping upper mold, and the stamping upper mold is connected to the stamping drive mechanism via the pull ears.

[0015] Beneficial Effects

[0016] The utility model provides a split stamping die for high-strength plates. It has the following beneficial effects:

[0017] (1) In this high-strength plate split stamping die, when the sliding lower die is located directly below the stamping upper die, multiple groups of lifting shafts extend upward through the fixed shaft sleeve under the extrusion of the bottom surface of the sliding long groove, and the workpiece plate is positioned by the multiple groups of lifting shafts extending upward. When the sliding lower die is away from the stamping upper die, the multiple groups of lifting shafts retract into the fixed shaft sleeve under the pulling force of the return spring, making it convenient for people to unload the workpiece plate after the stamping. By setting the lifting shaft that can freely extend and retract as the position of the sliding lower die moves, the effect of facilitating the unloading of the inwardly concave formed workpiece is achieved.

[0018] (2) This high-strength plate split stamping die uses a motor to drive the lead screw to rotate forward and backward, so that the lead screw drives the sliding lower die to slide back and forth on multiple sets of fixed rods, thereby facilitating the control of the position of the sliding lower die. During the position change process, the sliding lower die drives multiple sets of lifting shafts to freely extend and retract, which facilitates the positioning and unloading of the workpiece plate, thereby achieving the effect of improving the stamping production efficiency of the workpiece plate.
