Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, and in particular to a hydraulically controlled stamping device for a radial diffuser assembly. Background Art

[0002] Radial diffusers are widely used in fields such as drones. Diffusers are generated by centrifugal compressors and are devices that convert kinetic energy into static pressure energy. The components of radial diffusers involve a large number of components that need to be stamped, such as their cover plates. The radial diffuser cover plate is an annular stamping structure. After the steel plate is stamped, it is also necessary to perform punching and other processing operations in the middle. The current hydraulic control stamping device of radial diffuser components is widely used due to its advantages such as high processing efficiency. The current hydraulic control stamping device of radial diffuser components is subject to the limitations of the forming die. There are sharp burrs on the edges of the through holes produced by stamping, which is not convenient for automatic trimming of the punched holes after the steel plate is stamped. Subsequent grinding and trimming are required manually, and the processing continuity is poor, which affects the processing efficiency. At the same time, during the stamping process of the steel plate, the thickness of the steel plate is easily thinned by the extrusion tension under the extrusion of the stamping die, which is not convenient for automatic extrusion correction, affecting the stamping precision. At the same time, the outer edge of the radial diffuser cover plate after forming also requires cumbersome trimming work, which is not convenient for one-time trimming. Summary of the invention

The present structure adopts the lower die separation part 4, whose structure can be lifted and lowered. When it is necessary to punch the cover plate, it can be flush with the top of the retracting sliding cylinder 301, ensuring that the rotating seat 501 can move down normally for punching and ensure processing accuracy. At the same time, after the punching is completed, the lower die sliding cylinder 401 can be automatically moved down under the control of the stamping trimming part 5 to achieve separation from the bottom of the stamped cover plate.

When the rotating seat 501 is controlled to move down, the rotating seat 501 squeezes the cover plate blank to be punched to punch holes. At this time, the rotating seat 501 continues to move downward, and when the control electromagnet 502 on the rotating seat 501 moves downward to the position of a circle of plug pins 404, the magnetic attraction force can magnetically attract the connecting iron block 406 inward, pulling the plug pin 404 to retract inward, releasing the limit of the plug limit groove 3011, and under the traction of the counterweight ring 403, the lower mold sliding cylinder 401 will slide downward at this time, which is convenient for the subsequent grinding and deburring of the lower edge of the cover plate punching hole, and the expansion spring 503 is also used to ensure that the grinding sliding block 504 elastically fits the cover plate punching hole.

[0041] Embodiment 2, on the basis of embodiment 1, the pressing control unit 6 comprises: a pressing mounting frame 601, a pressing hydraulic cylinder 602, a pressing ring 603 and a pressing column 604, the pressing mounting frame 601 is fixedly mounted on the sliding mounting cylinder 104; two pressing hydraulic cylinders 602 are fixedly mounted on the pressing mounting frame 601; a pressing ring 603 is fixedly mounted on the output shaft of the two pressing hydraulic cylinders 602; a circle of pressing columns 604 is fixedly mounted on the bottom of the pressing ring 603, and the bottom of the circle of pressing columns 604 is an arc structure; a circle of pressing columns 604 is slidably plugged into the lower pressing plate 103; the rotary extrusion member 7 comprises: a lower The pressing rotating ring 701, the grinding ring 702 and the pressing return spring 703 are provided. The pressing rotating ring 701 is slidably sleeved on the lower pressing plate 103. The grinding ring 702 is fixedly installed at the bottom of the pressing rotating ring 701, and the bottom of the grinding ring 702 is a concave arc structure. The bottom of the grinding ring 702 is provided with a frosted grinding coating. The pressing rotating ring 701 is sleeved with a pressing return spring 703, and one end of the pressing return spring 703 is fixedly installed on the top of the pressing rotating ring 701, and the other end of the pressing return spring 703 is fixedly installed on the inner side of the lower pressing plate 103. The inner side of the grinding ring 702 is attached to the upper punch 1031. The grinding ring 70 2 is used to press the edge of the workpiece; the rotary extrusion piece 7 also includes: an inclined guide groove 704, a circle of inclined guide grooves 704 is set on the pressing rotating ring 701, and a circle of inclined guide grooves 704 are respectively attached to the end of a circle of pressing pillars 604. The rotary extrusion piece 7 can be used to press the outer edge of the stamping of the cover plate, which can compensate for the thickness reduction caused by the extrusion and stretching of the mold when the cover plate blank is punched, and can improve the stamping forming accuracy and the processing accuracy of the cover plate. At the same time, this structure can automatically rotate during the pressing process, and the pressing pressure is combined with the rotating friction to play the role of trimming and chamfering, thereby improving the manufacturing quality of the cover plate. Especially for the thicker radial diffuser cover plate, the processing quality of this structure can be guaranteed. The inclined guide groove 704 of the inclined surface can be squeezed by the pressing column 604, driving the downward pressing rotating ring 701 to rotate. At this time, the grinding ring 702 on the bottom arc surface will grind and trim the edge of the cover plate. At the same time, through the downward pressure, the outer ring of the stamped cover plate can be squeezed inward into the space between the upper punch 1031 and the forming lower die 3012 to compensate for the forming thickness of the cover plate at the bending part, especially the outer ring of the cover plate. This part is the stress-bending part obtained by stamping and bending. This structure can make the edge of the formed cover plate smooth and the stamping efficiency is high.

[0042] The working principle of this embodiment is as follows: first, the structure is welded on a workbench or placed on the ground, and the cover blank to be punched is placed on the forming lower die 3012. At this time, the electric heating plate 302 is turned on for heating, and the upper punch 1031 on the lower pressing plate 103 is driven downward by the lifting hydraulic cylinder 102 to realize the stamping of the cover. Then, the lower pressing column 202 is pushed downward by the secondary hydraulic cylinder 201, and the rotating seat 501 can be controlled to directly punch the middle part of the stamped cover and discharge it from the lower die sliding cylinder 401; when the rotating seat 501 is controlled to move downward, the rotating seat 501 squeezes the cover blank to be punched. As the rotating seat 501 continues to press down to achieve punching, the rotating seat 501 continues to move downward. When the control electromagnet 502 on the rotating seat 501 moves down to the position of a circle of plug pins 404, the magnetic attraction force can magnetically attract the connecting iron block 406 inward, pulling the plug pin 404 to retract inward, releasing the limit of the plug limit groove 3011, and under the traction of the counterweight ring 403, the lower mold sliding cylinder 401 will slide downward and separate from the bottom of the cover plate. At this time, as the rotating seat 501 continues to move downward, the driving motor 203 drives the rotating seat 501 to rotate, driving the grinding sliding block 504 to rotate. When a circle of punching is completed, the rotating seat 501 is driven by the motor 203. When the grinding slide block 504 is attached to the upper edge of the punching hole of the cover plate, grinding and deburring can be performed. As the rotating seat 501 continues to move downward, the inclined grinding slide block 504 is squeezed by the edge of the punching hole and will retract inward, compressing the expansion spring 503 until the grinding slide block 504 moves down to the lower edge of the punching hole of the cover plate. The upper side of the grinding slide block 504 will fit the lower edge of the punching hole of the cover plate to grind and deburr. The expansion spring 503 is also used to ensure that the grinding slide block 504 elastically fits the punching hole of the cover plate for grinding. As the rotating seat 501 of this structure continues to move downward, it will drive the control electromagnet 502 to align with the falling lower die slide. The lifting electromagnet 402 on the cylinder 401 is magnetically positioned, and at this time, the lifting hydraulic cylinder 102 is controlled to drive the rotating seat 501 to rise, which can drive the lower mold sliding cylinder 401 to rise together, until the plug pin 404 is inserted into the limit groove 3011 for positioning under the pressure of the lower mold separation spring 405. At this time, the rotating seat 501 continues to rise and is flush with the bottom of the upper punch 1031 for the next stamping. The method of magnetically controlling the electromagnet 502 by the lifting electromagnet 402 can provide a magnetic pulling force when moving up, and does not affect the control of the electromagnet 502 to continue to move up after the lifting electromagnet 402 is in place, thereby realizing automatic control;

[0043] After the upper punch 1031 is pressed down to stamp and form the cover plate, the stamped cover plate is heated by the electric heating plate 302 to soften it, and then driven by the downward hydraulic cylinder 602, the pressing column 604 is controlled to extrude the inclined guide groove 704, which is pressed and drives the grinding ring 702 on the downward pressing rotating ring 701 to fit the edge of the cover plate for pressing down. During the process, if there is a large thickness reduction problem at the bending part of the cover plate, the edge of the cover plate will be pressed between the upper punch 1031 and the forming lower die 3012 for compensation, so as to help improve the uniformity of the thickness of the cover plate after forming. At the same time, when the pressing column 604 presses down the inclined guide groove 704, the inclined guide groove 704 of the inclined surface can be squeezed by the pressing column 604, driving the downward pressing rotating ring 701 to rotate, and at this time, the grinding ring 702 on the arc surface of the bottom will grind and trim the edge of the cover plate to complete the stamping and forming of the radial diffuser cover plate.
