Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping equipment for submersible pump housings. Background Technology

[0002] The submersible pump housing is a crucial component of the pump, typically made of sheet metal formed into a cylindrical structure through stamping. Current submersible pump housing stamping equipment has been found to have areas for improvement in practical use. The traditional process involves stamping first, then removing the workpiece and placing it on a lathe or edge trimming machine for edge finishing, requiring additional manual operation. The stamping and edge trimming processes need to be separated, meaning the workpiece must be transferred to another cutting machine after stamping to remove excess edges. This not only increases equipment investment costs and operational steps but also requires additional manual control and occupies more space.

[0003] Therefore, a submersible pump housing stamping processing equipment capable of demolding, integrated stamping and cutting functions is designed to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as high equipment investment costs, numerous operation steps, excessive manual control, and large floor space, which result in separate stamping and cutting processes. Therefore, this invention proposes a stamping processing equipment for submersible pump housings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A submersible pump housing stamping equipment, comprising a frame; A punch is provided with a mounting base fixed on the worktable of the machine frame, and the punch is rotatably connected to the top of the mounting base; The demolding seat is slidably sleeved around the periphery of the punch. The punch is located above the die, and the punch, die, and ejector base are coaxial. The cutting blade is located on the machine frame worktable and on one side of the punch. The control element, located inside the punch, includes a crimping seat.

[0006] In one possible design, the bottom surface of the crimping seat protrudes beyond the bottom surface of the punch, ensuring that the crimping seat fits snugly against the workpiece to achieve pre-pressing.

[0007] In one possible design, hydraulic cylinder I and hydraulic cylinder II are respectively installed on the upper and lower parts of the frame. Hydraulic cylinder I is connected to the top of the punch to drive the punch to move. Hydraulic cylinder II is connected to a connecting seat located below the worktable of the frame. A connecting rod passing through the worktable is fixed between the connecting seat and the demolding seat to drive the demolding seat to move.

[0008] In one possible design, a lateral movement mechanism is also included, on which the cutting blade is mounted and moves laterally to cut off excess portions of the workpiece edge.

[0009] In one possible design, the control component further includes a motor, an outer cylinder that slides axially inside the punch, the motor is installed inside the outer cylinder, a pressing seat is connected to the output shaft of the motor, a telescopic rod is connected between the inner wall of the punch and the top of the outer cylinder, a compression spring is sleeved on the outer wall of the telescopic rod, and the two ends of the compression spring are respectively connected to the inner wall of the punch and the top of the outer cylinder to provide elastic pressure.

[0010] In one possible design, the traversing mechanism is either a pneumatic traversing mechanism or an electric traversing mechanism.

[0011] In this application, during actual use, the workpiece is placed on top of the punch and the ejector seat. Then, the hydraulic cylinder I is driven to move the punch downward. After the bottom surface of the pressing seat first comes into contact with the workpiece, the punch continues to move downward, and the compression spring is compressed until the bottom surface of the punch comes into contact with the workpiece. At this time, the punch and the ejector seat will clamp the workpiece, and the pressing seat is pressed against the workpiece by the force of the compression spring. Then, the hydraulic cylinders I and II are controlled simultaneously to drive the ejector seat and the punch downward in a synchronous manner. At this time, the inner wall of the punch and the outer wall of the punch cooperate to press the workpiece into a cylindrical shell. Then, hydraulic cylinder I is driven to move the punch upward until the bottom surface of the punch is flush with or slightly higher than the bottom surface of the pressing seat. At this time, the pressing seat will be pressed against the top of the punch by the force of the compression spring, which helps the workpiece to be demolded inside the punch. Then, the drive motor drives the pressing seat to rotate, and the pressing seat will press the workpiece and rotate together with the punch. At this time, the cutting blade is controlled to move and cut off the excess part of the workpiece edge by the feed force. After the end, the motor is stopped and the cutting blade and punch are reset. Then, hydraulic cylinder II is driven to move the demolding seat upward, thereby demolding the workpiece outside the punch.

[0012] In this utility model, the submersible pump housing stamping equipment, by setting a pressing seat and a compression spring, can press the workpiece onto the punch when the punch is reset, achieving initial demolding inside the punch. Then, the hydraulic cylinder II drives the demolding seat to move upward, pushing the workpiece out of the punch to complete the secondary demolding, avoiding workpiece jamming and ensuring a smooth demolding process. In this utility model, the submersible pump housing stamping equipment, through the self-drive of the pressing seat, can drive the housing to rotate after stamping, thereby cooperating with the lateral cutting blade to perform edge trimming, reducing subsequent processing steps. In this invention, the stamping mechanism and the cutting mechanism are integrated on the same frame through an integrated structure. After the workpiece is stamped, it can be directly cut at the edge without being transferred, which simplifies the operation steps, shortens the processing cycle, and reduces the equipment investment cost.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: a stamping processing equipment includes: a frame 1, a punch 6, a demolding seat 7, a punch 3, a cutting blade 4, and control components.

[0017] refer to Figure 1-3 The frame 1 is the basic support component of the equipment. A mounting base 8 is fixedly installed on its worktable. The punch 6 is rotatably mounted on the top of the mounting base 8. A demolding seat 7 is sleeved on the outer periphery of the punch 6. The punch 3 is located directly above the punch 6. The punch 3, the punch 6 and the demolding seat 7 are all located on the same axis to ensure the alignment of each component during stamping. The cutting knife 4 is set on the worktable of the frame 1 and located on one side of the punch 6. The control component is set inside the punch 3. The control component includes a pressing seat 10.

[0018] The bottom surface of the pressing seat 10 protrudes from the bottom surface of the punch 3. Hydraulic cylinder I2 and hydraulic cylinder II9 are respectively installed on the upper and lower parts of the frame 1. Hydraulic cylinder I2 is connected to the top of the punch 3 and is used to drive the punch 3 to move up and down. Hydraulic cylinder II9 is ​​connected to a connecting seat 11. The connecting seat 11 is located below the worktable of the frame 1. Multiple connecting rods are fixedly arranged between the connecting seat 11 and the demolding seat 7, and the connecting rods pass through the worktable of the frame 1. The demolding seat 7 can be driven to move along the axial direction of the punch 6 by the extension and retraction of hydraulic cylinder II9.

[0019] The equipment also includes a transverse mechanism 5, on which the cutting blade 4 is mounted. The transverse mechanism 5 can drive the cutting blade 4 to move laterally, thereby cutting off the excess parts of the workpiece edge. refer to Figure 4 The control components also include a motor 15. An outer cylinder 14 is slidably disposed inside the punch 3 along the axial direction. The motor 15 is installed inside the outer cylinder 14. The pressing seat 10 is connected to the output shaft of the motor 15. Multiple telescopic rods 13 are connected between the inner wall of the punch 3 and the top of the outer cylinder 14. A compression spring 12 is sleeved on the outer wall of the telescopic rod 13, and the two ends of the compression spring 12 are respectively connected to the inner wall of the punch 3 and the top of the outer cylinder 14. The telescopic rod 13 plays a guiding role, and the compression spring 12 can provide elastic pressure.

[0020] In practical use, the workpiece is first placed on top of the punch 6 and the demolding seat 7. Then, the hydraulic cylinder I2 is extended, which drives the punch 3 to move downward. When the bottom surface of the pressing seat 10 first comes into contact with the workpiece, the punch 3 continues to move downward. At this time, the outer cylinder 14 slides upward relative to the punch 3, the telescopic rod 13 retracts, and the compression spring 12 is compressed until the bottom surface of the punch 3 comes into contact with the workpiece. At this time, the punch 3 and the demolding seat 7 clamp and fix the workpiece. At the same time, the pressing seat 10 presses the workpiece under the elastic force of the compression spring 12. Then, hydraulic cylinders I2 and II9 are controlled simultaneously to drive the demolding seat 7 and punch 3 to move downward together. During this process, the inner wall of punch 3 and the outer wall of punch 6 cooperate to gradually press the workpiece into a cylindrical shell. After the stamping is completed, hydraulic cylinder I2 is driven to retract, which drives punch 3 to move upward until the bottom surface of punch 3 is flush with or slightly higher than the bottom surface of pressing seat 10. At this time, pressing seat 10 still holds the workpiece on the top of punch 6 under the action of compression spring 12, preventing the workpiece from moving upward with punch 3, thereby helping the workpiece to complete the demolding inside punch 3. Next, the drive motor 15 starts running, and the output shaft of the motor 15 drives the pressing seat 10 to rotate. Since the pressing seat 10 presses the workpiece, it drives the workpiece and the punch 6 to rotate together. At this time, the transverse mechanism 5 is controlled to drive the cutting blade 4 to move towards the edge of the workpiece. The excess part of the workpiece edge is cut by the force fed in. After the cutting is completed, the motor 15 stops running, and the transverse mechanism 5 is controlled to drive the cutting blade 4 to reset. At the same time, the hydraulic cylinder I2 continues to retract to make the punch 3 fully reset. Finally, the hydraulic cylinder II9 is ​​driven to drive the connecting seat 11 to move upward. The connecting seat 11 drives the demolding seat 7 to move upward through the connecting rod. The demolding seat 7 pushes the cylindrical shell out from the punch 6, completing the demolding of the outside of the punch 6 and completing the stamping process of the entire submersible pump shell.

[0021] This application can be used in the field of stamping equipment, or in other fields applicable to this application.

The structure of this embodiment is basically the same as the aforementioned embodiment, except that: the transverse mechanism 5 can be a pneumatic transverse mechanism or an electric transverse mechanism.
