Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wedges, and more specifically, to a novel wedge adjusting mechanism for a pull-down type free forging press. Background Art
[0002] At present, the moving parts and columns of a free forging press require a strong anti-eccentric load capacity. There is no constraint between the existing guide wedge and the guide sleeve (as shown at point A in Figure 6 ). During adjustment, it shows a free movement state. When adjusting the clearance between the adjusting wedge and the guide surface of the press column, it is impossible to ensure that the wedge moves straight up and down as a whole, resulting in the random separation of the contact surface between the wedge and the guide sleeve in an unconstrained state. As a result, there will be a large clearance at one end and a small clearance at the other end between the flat side of the wedge and the guide surface of the column, making it impossible to ensure uniform force on the wedge. When the moving part is subjected to an eccentric load and fits against the wedge, the entire flat surface of the wedge cannot be pressured, resulting in local stress, which not only weakens the anti-eccentric load effect but also increases local abnormal wear and affects the service life of the wedge. Summary of the Utility Model
[0003] To make up for the above deficiencies, the utility model provides a novel wedge adjusting mechanism for a pull-down type free forging press, aiming to improve the problem that the wedge cannot be uniformly stressed, resulting in eccentric wear of the wedge, abnormal loss, and reduced service life of the wedge.
[0004] The utility model is implemented as follows: A novel wedge adjusting mechanism for a pull-down type free forging press includes a guide sleeve and a wedge. The wedge is slidably connected to the inner wall of the guide sleeve. A limit strip is fixedly installed on one side of the wedge. The limit strip is T-shaped, and a limit groove matching the limit strip is provided on the inner wall of the guide sleeve.
[0005] In a preferred technical solution of the utility model, a plurality of mounting holes are provided on the limit strip. The limit strip is fixedly connected to one side of the wedge through the cooperation of the mounting holes and bolts. Threaded holes matching the bolts are provided on one side of the wedge, and the plurality of threaded holes correspond to the plurality of mounting holes one by one.
[0006] In a preferred technical solution of the utility model, the cross-section of the mounting hole is T-shaped.
[0007] In a preferred technical solution of the utility model, a positioning pin is fixedly installed on one side of the limit strip. A positioning hole matching the positioning pin is provided on one side of the wedge, and the positioning pin is cylindrical.
[0008] In a preferred technical solution of the utility model, there are a plurality of positioning pins, and the plurality of positioning pins and the plurality of mounting holes are staggered on the limit strip.
[0009] In the preferred technical solution of the present utility model, the limiting strips are symmetrically installed on one side of the inner wall of the wedge.
[0010] The beneficial effects of the present utility model are as follows: A new wedge adjusting mechanism for a pull-down type free forging press obtained through the above design. Insert the positioning pin on one side of the limiting strip into the positioning hole on one side of the wedge, and then fix it by passing a bolt through the mounting hole and cooperating with the threaded hole. The guide sleeve is sleeved on the outside of the wedge, and at the same time, the limiting strip is inserted into the limiting groove. This device improves the anti-eccentric load capacity of the wedge of the pull-down type free forging press, enables the wedge to be evenly stressed, avoids abnormal wear caused by eccentric wear of the wedge, and delays the service life of the wedge.
