Description

Technical Field

[0001] This utility model relates to the field of manifold drilling technology, and in particular to a multi-station transfer stamping die for stator housing. Background Technology

[0002] In the field of stator housing stamping production, traditional single-station stamping dies are widely used. Each stamping operation is a single process, and the production of the entire stator housing requires multiple clamping and die changes, which is cumbersome. Due to frequent manual intervention during the production process, not only is the production efficiency low, but it is also difficult to ensure the positioning accuracy of the workpiece during repeated clamping, resulting in large product size deviations and a high scrap rate. This cannot meet the needs of modern manufacturing industry for large-scale, high-precision production of stator housings.

[0003] To address this issue, multi-station transfer stamping dies have emerged. These dies integrate multiple stamping processes into a single mold, using an automated transfer mechanism to allow workpieces to be stamped sequentially between different stations. This eliminates the need for frequent manual clamping and mold changing, significantly improving production efficiency while reducing errors caused by manual operation and effectively ensuring product precision and consistency.

[0004] However, multi-station transfer stamping dies integrate multiple stamping processes and complex transfer mechanisms, making the die structure extremely complex and thus significantly increasing manufacturing costs. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station transfer stamping die for stator housing, which solves the problem of complex structure of multi-station transfer stamping dies, resulting in significantly increased manufacturing costs.

[0006] To achieve the above objectives, this utility model provides a multi-station transfer stamping die for a stator housing, including a base and a fixed plate. The top of the base is provided with multiple mold mechanisms for multiple stamping. The outer wall of the base is provided with a transfer component for transferring workpieces. The inner side of the mold mechanism is provided with an unloading mechanism. The top of the transfer component is provided with a stabilizing component.

[0007] The mold mechanism includes a hydraulic rod, which is disposed on the top of the fixed plate. The bottom of the hydraulic rod passes through the top of the fixed plate and is fixedly connected to a mounting plate. Multiple guide columns are fixedly connected to the top of the mounting plate. An upper mold assembly is disposed on the bottom surface of the mounting plate. A lower mold base is fixedly connected to the top surface of the base. A lower mold is fixedly connected to the top surface of the lower mold base.

[0008] The transmission component includes a rotating shaft, one end of which is rotatably connected to the outer wall of the base. A rotating rod is fixedly connected to the outer wall of the rotating shaft. A driving component is provided on the outer wall of the base. A synchronization component is provided on the outside of the driving component. A telescopic rod is fixedly connected to the top of the rotating rod. A clamp is provided at the other end of the telescopic rod.

[0009] The upper mold assembly includes a pad, the top of which is fixedly connected to the top of a fixing plate, and the bottom of which is fixedly connected to an upper mold.

[0010] The drive assembly includes a cylinder, which is fixedly connected to the outer wall of the base. A sliding rod is fixedly connected to one end of the cylinder, and a limit sleeve is slidably connected to the outer wall of the sliding rod. The outer wall of the limit sleeve is fixedly connected to the outer wall of the base.

[0011] The synchronization component includes a fixed stake, which is fixed to the outer wall of the sliding rod, and the outer wall of the rotating rod is provided with a clearance groove.

[0012] The unloading mechanism includes a limiting plate, the outer wall of which is fixedly connected to the outer wall of the lower mold, a spring is fixedly connected to the bottom of the lower mold, and an unloading plate is fixedly connected to the top of the spring.

[0013] The stabilizing component includes a bearing, the inner wall of which is fixedly connected to one end of a telescopic rod, and an angle adjustment device is fixedly connected to the outer wall of the clamp.

[0014] The upper mold assembly corresponds to the lower mold, and the rotating shaft is located at the midpoint between two adjacent lower molds.

[0015] In this utility model, a multi-station transfer stamping die for stator housing is used for stamping. The fixing plate is fixed on the equipment, the workpiece is placed in the lower die, the hydraulic rod is activated, and the hydraulic rod presses the mounting plate downward, so that the upper die is pressed into the corresponding lower die to stamp the workpiece. The guide column ensures that the mounting plate is pressed vertically downward. After stamping is completed, the upper die is lifted, and the workpiece is ejected by the spring force of the stripper plate, thus realizing the demolding of the workpiece. Then, with the help of the transfer assembly, the workpiece is transferred to the next die for the next stamping step.

[0016] After the workpiece is stamped, it is ejected from the mold. The two telescopic rods extend synchronously, and the two clamps clamp the workpiece. The cylinder retracts, pulling the sliding rod, which causes the fixed post to slide in the clearance groove. The rotating rod rotates around the rotating axis, and the telescopic rod fixed at the top of the rotating rod also rotates, moving the clamped workpiece to the next mold. During the movement, the stabilizing component ensures the orientation of the workpiece and prevents it from tilting, allowing it to accurately enter the next mold for processing. The structure is simple, the cost is low, and it can complete multi-station stamping transfer, greatly accelerating the processing efficiency. Attached Figure Description

During the movement, the stabilizing component 6 ensures the orientation of the workpiece and prevents it from tilting, allowing it to accurately enter the next mold for processing. The structure is simple and the cost is low. It can complete multi-station transfer stamping and greatly speed up the processing efficiency.
