Locking device for high-speed punching and indexing box

Abstract

The invention discloses a locking device for a high-speed punching and indexing box. The locking device comprises a long-strip-shaped metal block, wherein a mounting hole is formed in the middle upper part of the metal block; and a locking bolt penetrates through the mounting hole for mounting the metal block on a box body at the lower side of the box door of the indexing door. Compared with the prior art, the locking device has the beneficial effects that: the mounting hole is formed in the middle upper part of the metal block, and under the action of gravity, a short end of the metal block faces upwards; the length of the short end of the metal block is greater than the length from a mounting position of the mounting hole to the lower edge of the box door, and therefore, the box door of the indexing door can be locked by the metal block, an oil leakage phenomenon caused by opening the box door of the indexing box because of high-speed punching is avoided, the environmental quality is guaranteed, and the waste is avoided.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and relates to the locking of an indexing box door of a high-speed punching machine, and is especially suitable for a large-tonnage high-speed punching machine, and particularly relates to a locking device for a high-speed punching indexing box. Background technique [0002] In the prior art, during the use of high-speed punching machines, due to the sharpening of the mold, it is often necessary to open the door of the indexing box to adjust the gap between the gears to ensure the accuracy of the punching size. However, due to frequent operations, the door of the indexing box The locking screw on the top will slip. During the use of the high-speed punching machine, the door of the indexing box is easy to open due to factors such as vibration. At this time, the lubricating oil lubricating the indexing gear is thrown to the indexing box by centrifugal force. On the inner side of the door, wh...

[0002] In the prior art, during the use of high-speed punching machines, due to the sharpening of the mold, it is often necessary to open the door of the indexing box to adjust the gap between the gears to ensure the accuracy of the punching size. However, due to frequent operations, the door of the indexing box The locking screw on the top will slip. During the use of the high-speed punching machine, the door of the indexing box is easy to open due to factors such as vibration. At this time, the lubricating oil lubricating the indexing gear is thrown to the indexing box by centrifugal force. On the inner side of the door, when the indexing box door is in a half-closed state, the lubricating oil drips along the unlocked indexing box door and falls to the ground, causing a waste of lubricating oil and affecting the environmental quality of the factory area
