Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1, the embodiment of the utility model provides a helical blade pressure forming machine, including workstation 1, set up mounting bracket 8 on workstation 1, the fixed lifting drive mechanism 5 that is provided with on mounting bracket 8, lifting drive mechanism 5 is pneumatic cylinder or other current known elevation structure, as shown in fig. 1, lifting drive mechanism 5 is fixed in on mounting bracket 8, and mounting bracket 8 is worn out down to its output, and is fixed with upper mounting panel 6.

An upper forming die is fixed on the upper mounting plate 6, a lower mounting plate 9 is detachably arranged on the workbench 1 below the upper forming die, a lower forming die is fixedly arranged on the lower mounting plate 9, the upper forming die comprises a cylindrical upper die body 22, the lower edge of the upper die body 22 is spiral, an upper pressing sheet 3 is arranged on the lower edge of the upper die body 22, the lower forming die comprises a cylindrical lower die body 21, a spiral lower pressing sheet 4 is wound outside the lower die body 21, and the upper pressing sheet 3 and the lower pressing sheet 4 are identical in shape and correspond up and down.

The blade to be processed is of a circular ring-shaped sheet structure with an opening, the circular ring-shaped blade to be processed is placed on the lower pressing sheet 4 along the cylindrical lower die body 21, and the opening position of the circular ring-shaped blade to be processed is aligned with the edge position of the upper end of the lower pressing sheet 4. The sliding friction force between the inner ring of the blade to be processed and the lower die body 21 enables the blade to be fixed on the lower die body 21, the lifting driving mechanism 5 is started to enable the upper die body 22 to be pressed downwards, and the blade to be processed forms a spiral between the upper pressing sheet 3 and the lower pressing sheet 4 after being pressed.

A plurality of guide sliding sleeves 13 penetrating through the mounting frame 8 are fixedly arranged on the mounting frame 8, guide sliding rods 12 are arranged in the guide sliding sleeves 13 in a sliding mode, and the lower ends of the guide sliding rods 12 are fixedly connected with the upper mounting plate 6. The arrangement of the guide sliding sleeve 13 and the guide sliding rod 12 can effectively improve the stability of the pressing movement, and in the using process, lubricating oil needs to be regularly coated on the guide sliding rod 12 so as not to influence the operation of the equipment.

As shown in fig. 2, a limiting plate 11 is fixedly arranged between the upper end and the lower end of the lower pressing plate 4, and the limiting plate 11 is vertically arranged. The upper and

lower blades

3 and 4 approach a complete helix. The limiting plate 11 is arranged to abut against the opening end face of the blade to be processed, so that the blade to be processed is prevented from rotating around the circumferential direction of the lower die body 21 in the pressing process.

The top of the limiting plate 11 protrudes out of the highest point of the lower pressing plate 4, so that the positioning of the blade to be processed is facilitated. When the blade to be processed is placed, the opening end face of the blade is abutted against the surface of the limiting plate 11.

A plurality of reinforcing ribs 10 are fixed between the lower pressing plate 4 and the lower mounting plate 9 and between the upper pressing plate 3 and the upper mounting plate 6. The arrangement of the reinforcing ribs 10 can prolong the service life of the upper pressing sheet 3 and the lower pressing sheet 4, and prevent the upper pressing sheet and the lower pressing sheet from being damaged or deformed due to large pressure bearing for a long time.

The upper surface of the lower die body 21 is higher than the highest point of the lower pressing sheet 4, the top of the lower die body 21 is chamfered, as shown in fig. 1 and 2, and an installation guide part 7 is formed after the top of the lower die body 21 is chamfered, so that the blade to be processed is sleeved on the lower die body 21.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
