[0022] The present utility model will be further described in detail below in conjunction with the accompanying drawings. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary instructions, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0023] As Figures 1-5 shown, a roundness correction device for a double-cone liner includes an upper die cover plate 1, an insert-fixed upper die plate 2, a slider seat 3, a lower die fixed plate 4, and a lower die bottom plate 5;

[0024] The insert-fixed upper die plate is fixedly connected to the upper die cover plate. Two sliders 6 and an upper profiling insert 7 are fixedly installed downward on the insert-fixed upper die plate. The surfaces of the sliders facing each other have slider inclined surfaces 8 that are inclined downward; the slider seat is fixedly installed on the lower die fixed plate, and the lower die fixed plate is fixedly installed on the lower die bottom plate; the slider seat is provided with a chute, and two slider shovels 9 are slidably fitted in the chute. The outer sides of the slider shovels have shovel inclined surfaces, and the slider inclined surfaces can slidably fit with the shovel inclined surfaces; the slider shovels are fixedly installed with side profiling inserts 10, and the side profiling inserts have side profiling grooves 11; the lower die fixed plate is fixed with a fixed seat 12, the slider seat is provided with a relief hole facing the fixed seat, and the lower die bottom plate is fixedly installed upward with a lower profiling core 13, and the lower profiling core extends upward through the fixed seat between the two side profiling inserts.

[0025] In this way, when correcting the roundness of the double-cone liner, the double-cone liner is sleeved outside the lower profiling core. Then the upper die cover plate moves downward, driving the insert-fixed upper die plate and the upper profiling insert to move downward. The sliders abut against the slider shovels, and the slider inclined surfaces push the shovel inclined surfaces to move, thereby driving the slider shovels to move in the chute, causing the two side profiling inserts to approach each other, and using the side profiling grooves to correct the roundness of the double-cone liner, and the lower profiling core supports the double-cone liner. The structure is simple and stable.

[0026] During implementation, the insert-fixed upper die plate is fixed with two inclined guide posts 14, and the shovel sliders are provided with inclined holes that are slidably fitted with the inclined guide posts. Through the setting of the inclined guide posts, when the upper die cover plate moves downward, the inclined guide posts will drive the slider shovels to move, playing a role of pre-guidance. When moving in place, the sliders contact the slider shovels.

[0027] During implementation, guide blocks 15 are convexly arranged on both sides of the lower end of the slider shovel base. The slider seat is provided with guide grooves 16 that are slidably matched with the guide blocks, and the guide grooves communicate with the sliding grooves. This facilitates the stable installation of the slider shovel base.

[0028] During implementation, an installation groove is recessed in the fixed seat, and a compression spring 17 is arranged in the installation groove. The outer end of the compression spring abuts against the slider shovel base. This facilitates that after the upper die cover plate resets upward, the compression spring pushes the slider shovel base to move outward and reset, thereby driving the side profiling insert to move outward, facilitating the removal of the corrected double-cone liner.

[0029] During implementation, four guide posts 18 are fixedly installed on the lower die fixing plate, and the slider seat and the insert fixing upper template are fixed with guide sleeves 19 that are slidably matched with the guide posts. This facilitates guiding the movement of the upper die cover plate.

[0030] This correction device is installed on a single-column hydraulic press table and fixed by bolts and press plates. The hydraulic press pressure is set to 3.5T, the downward pressure time is 2S, and the pressure holding time is 2s. This device can change the vertical pressure applied by the single-column hydraulic press on the device to a horizontal pressure, and the pressure acts on the side profiling insert in the device. By extruding with the workpiece, the workpiece deforms, and through this correction method, the workpiece reaches the qualified size range, and the extrusion method makes the part size regular.

[0031] Finally, it should be noted that those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these changes and modifications.
