Description

Technical Field

[0001] The present invention relates to the technical field of extrusion of rotor pump accessories, and particularly relates to an auxiliary extrusion device for the production of rotor pump accessories. Background Art

[0002] When processing related accessories of a rotor pump, such as key components like rotors and pump bodies, for the extrusion devices currently applied to the processing of rotor pump accessories, there are obvious shortcomings in their processing procedures. Firstly, manual clamping of the accessories is required, which not only consumes manpower, but also, due to the differences in manual operations, it is difficult to ensure that the clamping force and position are exactly the same each time, thus laying a hidden danger of unstable quality for subsequent extrusion operations. Only after the manual clamping step is completed can the extrusion operation be carried out.

[0003] However, during the extrusion process, since the extrusion device needs to perform all-round extrusion work on the rotor pump accessories but cannot perform automatic steering adjustment operations, this means that during actual extrusion operations, operators need to continuously intervene manually to try to adjust the direction of the accessories to achieve an all-round extrusion effect. However, manual adjustment is not only inefficient but also difficult to precisely control the steering angle and position of the accessories, resulting in the extrusion work not achieving the ideal effect, and there are obvious limitations in the actual use of the extrusion device.

[0004] Moreover, when extruding rotor pump accessories, the device cannot perform multi-directional steering operations on the accessories. The shapes and structures of the accessories of rotor pumps are diverse and complex, and during the processing, extrusion from multiple directions is often required to meet the design requirements. However, due to the lack of the ability to perform multi-directional steering operations, the existing extrusion devices make it difficult to fully process the rotor pump accessories. Some key parts of the accessories may not be effectively extruded, thus affecting the processing quality of the rotor pump accessories. At the same time, due to insufficient processing, multiple reworks and repairs may be required, which undoubtedly greatly reduces the production efficiency and increases the production cost.

The screw rod passes through the moving seat and is matched with the moving seat. A semi-gear is installed on the outer side of the screw rod, and a rack A is installed inside the moving seat.

[0009] Optionally, a guide post is fixedly connected to the top surface of the base. A longitudinal groove is formed inside the guide post. An electric push rod B is installed inside the longitudinal groove of the guide post, and a moving block A is slidably connected inside the longitudinal groove of the guide post. The electric push rod B is used to push the moving block A to move. An electric push rod C is installed on the side of the moving block A close to the guide rail, and the detection head is installed at the end of the electric push rod C away from the moving block A.

[0010] Optionally, the limiting claw is used to clamp the fitting. The limiting claw is rotatably connected to the moving block B. An internal ratchet B is coaxially installed between the limiting claw and the moving block B. The internal ratchet B is matched with the rack B, and the internal ratchet B and the rack B together form a transmission structure.

[0011] Optionally, two electric push rods A are installed inside the transverse member of the guide rail, and the two electric push rods A are installed oppositely. A sliding seat is installed inside the transverse member of the guide rail. The electric push rod A is used to push the sliding seat to move. A longitudinal groove is formed inside the sliding seat, and a motor is installed inside the longitudinal groove of the sliding seat.

[0012] Optionally, the rack A is matched with the semi-gear. An extrusion claw is fixedly connected to the inner side of the moving seat.

[0013] Beneficial effects According to the extrusion device of an embodiment of the present invention, compared with the traditional one, the position of the sliding seat inside the guide rail is adjusted by starting the electric push rod A installed inside the guide rail. The sliding seat moves towards one side of the bearing seat. When the sliding seat moves towards one side of the bearing seat, the workpiece placed on the bearing seat can be squeezed and closed by the synchronous approach of the extrusion claws arranged on both sides of the bearing seat. Through the synchronous clamping of the two extrusion claws, a full - range squeezing and closing operation is performed on the workpiece placed on the bearing seat, thereby achieving a more practical purpose. When the sliding seat slidingly connected inside the guide rail moves away from the bearing seat under the pushing action of the electric push rod A, the rotation of the bearing seat can be driven by the engagement of the rack C fixedly connected to one side of the sliding seat and the internal ratchet A installed on the bottom side of the bearing seat. When the bearing seat rotates, the workpiece placed above it can be synchronously driven to perform a one - way rotation adjustment operation, thereby achieving the design of automatically flipping the workpiece during the extrusion work to achieve the purpose of full - range extrusion processing, avoiding the problems of low work efficiency and potential safety hazards easily caused by manual flipping.

[0014] In addition, in the present invention, when performing the extrusion forming work on the workpiece, the position of the moving block A inside the guide post can be adjusted by starting the electric push rod B installed inside the guide post, and the detection head can be pushed outwards by starting the electric push rod C installed on one side of the moving block A, so that the detection head contacts the surface of the workpiece. Then, the rotation of the bearing seat drives the workpiece to rotate, so as to achieve an accurate detection operation on whether the surface of the workpiece is extruded and formed to meet the standard, thereby achieving a more practical purpose. When the pressing plate installed at the bottom of the hydraulic push rod resets upwards, the rotation of the workpiece can be driven by the engagement of the rack B fixedly connected to the rear side thereof and the internal ratchet B installed at the rear side of the limit claw through the limit claw, thereby achieving the purpose of improving work efficiency instead of manual labor.

[0015] In addition, in the present invention, when it is necessary to perform longitudinal extrusion work on the workpiece placed on the bearing seat, the workpiece can be placed at the internal position of the limit claw, and then the pressing plate can be moved downwards by starting the hydraulic push rod installed at the bottom of the transverse member in the support column. When the pressing plate moves downwards, the longitudinal extrusion operation on the workpiece placed on the bearing seat can be automatically performed, thereby achieving the purpose of full - range forming. And when the height of the moving seat installed on the sliding seat through the spring rod is adjusted, the pushing rod slidingly connected inside the extrusion claw can be driven to perform a slight straightening operation on the fitting by the engagement of the semi - gear installed on the outside of the screw rod and the rack A slidingly connected inside the moving seat, thereby achieving the purpose of assisting the extrusion forming.
