Description

Circular blank auxiliary positioning frock

Technical Field

The utility model relates to a mould forges the field, particularly, relates to a circular blank assistance-localization real-time frock for the location of circular blank in the deep chamber mould of auxiliary adjustment.

Background

In the forging process, when a deep hole type die cavity forging manipulator clamps a blank, the blank cannot go deep into a die cavity to be positioned, and only the round blank can be clamped above the die cavity, as shown in fig. 1 of the attached part. After the manipulator is loosened, the blank freely falls into the cavity, the blank is placed incorrectly and is inclined after the blank falls into the cavity in a suspended mode, the blank needs to be placed correctly through manual auxiliary operation in the follow-up process, and forging is carried out after the blank is placed in the middle. The defect of the mode is that the manipulator can perform high-precision suspension positioning, but cannot meet the requirement of the position precision of the blank falling into a die cavity, manual secondary rough adjustment is needed, the blank is easy to be skewed, and the problem of uneven deformation is brought to forging.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a circular blank assistance-localization real-time frock for the location of circular blank in the deep chamber mould of auxiliary adjustment.

The utility model adopts the following technical scheme:

the utility model provides a circular blank assistance-localization real-time frock, includes the setting element, and the setting element is the arc holding ring, and the outer cambered surface of holding ring coincide with the die cavity inner cambered surface of mould, and the inner cambered surface of holding ring coincides with the outer cambered surface of circular blank, and the rigid coupling full thread double-screw bolt of holding ring top, full thread double-screw bolt and holding ring bracket threaded connection.

The utility model discloses a location frock's advantage lies in, simple structure avoids direct manual contact blank, has realized blank position adjustment, prevents that follow-up forging in-process from causing the product quality defect because the metal flows inequality, has improved forging product percent of pass.

Furthermore, the holding ring bracket comprises a head elbow and a holding rod, wherein one end of the head elbow is provided with an internal thread matched with the external thread on the full-thread bolt, and the other end of the head elbow is fixedly connected with or in threaded connection with the holding rod.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments. It is to be understood that the following description is only for purposes of clearly illustrating the present invention and is not to be taken in a limiting sense.

Fig. 1 shows a prior art in which a robot 4 moves a blank 3 heated to a temperature above a cavity 2 of a deep hole die 1 at an initial stage of forging. The robot 4 is then released to drop the blank 3 into the mold cavity 2, which may cause the blank 3 to be out of position, tilted, etc.

Referring to fig. 2, the utility model discloses a circular blank assistance-localization real-time frock is shown, comprises holding ring 5, full thread double-screw bolt 6 and holding ring bracket. The positioning ring 5 is of an arc-shaped structure, the outer arc surface of the positioning ring 5 is matched with the inner arc surface of the die cavity 2 of the die 1, the inner arc surface of the positioning ring 5 is matched with the outer arc surface of the circular blank, a full-thread stud 6 is fixedly welded above the positioning ring 5, and the full-thread stud 6 is in threaded connection with the positioning ring bracket. The locating ring bracket comprises a head elbow 7 and a holding rod 8, wherein an internal thread matched with the external thread on the full-thread stud 6 is arranged inside one end of the head elbow 7, and the other end of the head elbow 7 is connected with the holding rod 8. The holding rod 8 is a round rod, and can be fixedly connected with the head elbow by using the round rod with the diameter smaller than the inner bore diameter of the head elbow 7, and can also be connected with the round rod through threads with external threads matched with the internal threads of the head elbow at the end part. The positioning ring 5 is in threaded connection with the positioning ring bracket through the full-thread stud 6, and the positioning rings 5 of different specifications can be replaced aiming at circular blanks of different specifications.

The working process of the utility model is as follows:

after the manipulator 4 drops the blank 3 into the die cavity 3, a worker holds the holding rod 8 to place the positioning ring 5 of the positioning tool 10 in the gap between the die cavity 1 and the blank 3, and adjusts the position of the positioning tool to enable the outer arc surface of the positioning ring 5 to be tightly attached to the inner arc surface of the die cavity 2. Another worker uses the elbow crowbar 9 to abut against the blank 3 on the opposite side of the positioning tool 10, so that the outer arc surface of the blank 3 abuts against the inner arc surface of the positioning ring 5, as shown in fig. 3 and 4. The position of the blank 2 is adjusted under the cooperation of two workers, the elbow crowbar 9 is taken away, the positioning tool 10 is lifted, and the forging process is started.

The utility model discloses a location frock simple structure has avoided because the manipulator places the blank anchor clamps and loosens and lead to blank position dislocation in the twinkling of an eye, prevents to follow-up forging in-process because the metal flows inequality and causes the product quality defect, has improved forging product percent of pass.

The above description is only the preferred embodiment of the present invention. Various modifications and equivalent changes may be made by those skilled in the art without departing from the spirit and scope of the present invention, and such modifications and changes are intended to be included within the scope of the present invention.
