Description

Technical Field

[0001] The utility model relates to the technical field of forging processing, in particular to an auxiliary bracket for processing ring forgings. Background Art

[0002] Ring forgings are a product of the forging industry and a type of forging. They are ring-shaped objects that are formed by applying external force to metal billets and forming them into suitable compression forces through plastic deformation. The forging process builds a refined grain structure and improves the physical properties of the metal. Ring forgings can be seen everywhere in daily life and are an industrial product.

[0003] When processing ring forgings, they need to be placed and positioned in advance. Commonly used auxiliary brackets can usually only adapt to a single size. Positioning ring forgings of multiple sizes is relatively cumbersome, which increases the time for taking and placing, and prolongs the overall processing time. Utility Model Content

[0006] The driving assembly includes a motor, a bidirectional screw, a movable plate, a connecting arm, a support plate and a pin shaft 1. The bidirectional screw is fixedly connected to the output end of the motor, and the movable plate is installed on the bidirectional screw in two groups opposite to each other. The pin shaft 1 is detachably installed on the support plate through a nut, and the two sides of the movable plate are movably connected to the corresponding two support plates through the connecting arm and the pin shaft 1.

[0007] By adopting the above technical solution, ring forgings of various sizes can be quickly placed and positioned, and can be easily removed after processing.

[0008] A protective shell having the same height as the support plate is also installed in the middle of the support platform, and the protective shell is used to protect the middle of the bidirectional lead screw.

[0009] By adopting the above technical solution, the middle position of the bidirectional lead screw can be protected.

[0010] An annular groove is provided in the middle of the edge of the support plate, and a plurality of through holes for the first pin and the second pin to pass through are provided around the upper end of the support plate.

[0011] By adopting the above technical solution, corresponding adjustments can be made according to the size of the ring forging.

[0012] The limiting end is rotatably mounted at the middle position of the second pin shaft.

[0013] By adopting the above technical solution, the limiting end is movably arranged to facilitate adjustment and to limit the outer wall of the ring forging.

[0014] The center point of the bidirectional lead screw and the center lines of the four groups of support plates are on the same vertical section.

[0015] By adopting the above technical solution, the device as a whole can be easily adjusted and the ring forging can be positioned.

[0016] The beneficial effects of the auxiliary bracket for ring forging processing of the utility model are:

[0017] The ring forgings are placed on four groups of support disks, and then the motor can be driven to drive the two groups of movable plates to move in both directions through the bidirectional lead screw. The movable plates push the upper ends of the support disks to rotate through the connecting arms. While the support disks rotate, the second pin shaft and the limit end are pushed until the limit end abuts against the side wall of the ring forging to limit it. This device is convenient for quickly placing the ring forgings, limiting and locking them, and improving the positioning operation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] A protective shell 11 with the same height as the support plate 6 is also installed in the middle of the support platform 1, and the protective shell 11 is used to protect the middle part of the bidirectional screw 3; the protective shell 11 is installed in the middle of the support platform 1, and when placing the forgings, the support plate 6 and the protective shell 11 can both support the ring forgings, and the debris generated during the processing of the ring forgings can be prevented from falling onto the bidirectional screw 3 and affecting the normal transmission of the bidirectional screw 3 and the movable plate 4.

[0027] An annular groove is provided in the middle of the edge of the support plate 6, and a plurality of through holes are provided around the upper end of the support plate 6 for the pin shaft 1 7 and the pin shaft 2 9 to pass through; the annular groove can facilitate the movable connection between the end of the connecting arm 5 and the pin shaft 1 7, and when the movable plate 4 moves, the support plate 6 can be pulled to rotate by the connecting arm 5.
