Abstract

The utility model provides a spacing guider of pressure flitch on cope match-plate pattern, includes: fix the lock of screw hole in upper die base upper end attaches the piece, link up the upper die base and press the core bar of screw assembly on lock attaches a screw hole of piece through the upper end with pressing the flitch, the cover link up the upper die base on the core bar and press the tubular guide pillar of flitch, the screw fastening through interface department is at the guide pin bushing on pressing the flitch, the cover is stretched out the stopper of the core bar tip of pressing the flitch downside at the threaded rod, the assembly is at core bar lower extreme locking stopper nut, pass the nut anticreep split pin of nut and core bar, guide pin bushing and guide pillar sliding fit wherein, set up the adjustment cover under between stopper and guide pillar the utility: the anti-dropping and guiding device has the advantages that the anti-dropping and guiding of the pressure plate are realized through the core bar and the guide pillar which are coaxially arranged, and compared with a traditional pressure plate anti-dropping device, the anti-dropping device is small in occupied space and convenient to disassemble and assemble, and the manufacturing cost of the anti-dropping and guiding device of the pressure plate is reduced.

Description

Limiting and guiding device for pressure plate on upper die base

Technical Field

The utility model belongs to the mechanical equipment field, concretely relates to stamping die.

Background

In the stamping production, the pressure plate assembled on the upper die holder is provided with an anti-drop and guiding device relative to the upper die holder. The existing anti-drop and guide device is shown in fig. 1, and adopts a structure in which the anti-drop device and the guide device are respectively arranged, wherein the anti-drop device comprises a locking screw 1 passing through a pressure plate 6 and locked on an upper die holder 5, and a sliding sleeve 7 sleeved on the locking screw. The screw 1 locks the sliding sleeve 7 on the die holder 5 through the end cap, and the shoulder at the lower end of the sliding sleeve 7 blocks the pressure plate 6 from separating from the die holder 5. The guide device comprises a guide post 2 penetrating into an assembly hole in a top plate from the lower side of the top plate of a die holder 5, the guide post 2 is attached to the die holder through a lock, an annular pressure plate 3 limiting the guide post 2 on the die holder 5 is pressed by a protruding part of the guide post, a guide sleeve 4 is fastened on the pressure plate 6 through a screw at an interface, the guide post 2 is inserted into the guide sleeve 4 and is in sliding fit with the guide sleeve, a radial annular protrusion is arranged at the lower port of the assembly hole of the guide post 2 and the upper die holder, and the guide post 2 is fixed on the upper die holder 5 through the lock attachment plate 3 protruding from a stop ring. The pressure flitch anticreep device and the guider that set up respectively, occupation space is great on the mould, to the not enough mould of some inner space, leads to anticreep and guider or other auxiliary device installation difficulties.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a spacing guider of pressure flitch on upper die base for on the automatic stamping production line, overcome the above-mentioned not enough that current spacing guider exists.

The utility model discloses an anti-drop and guider include: the die comprises a locking block fixed at the upper end of an upper die holder and provided with a threaded hole, a core rod penetrating through the upper die holder and a pressure plate and assembled on the threaded hole of the locking block through threads at the upper end, a tubular guide pillar sleeved on the core rod and penetrating through the upper die holder and the pressure plate, a guide sleeve sleeved on the guide pillar and embedded in a through hole of the guide pillar of the pressure plate, a limiting block sleeved on the end part of the core rod, extending out of the lower side face of the pressure plate, of the core rod, a nut assembled at the lower end of the core rod and used for locking the.

In order to facilitate the anti-falling and the manufacturing and the assembly of the guide device, an adjusting sleeve is arranged between the limiting block and the guide column.

The utility model has the advantages that: the anti-dropping and guiding device has the advantages that the anti-dropping and guiding of the pressure plate are realized through the core bar and the guide pillar which are coaxially arranged, and compared with a traditional pressure plate anti-dropping device, the anti-dropping device is small in occupied space and convenient to disassemble and assemble, and the manufacturing cost of the anti-dropping and guiding device of the pressure plate is reduced.

Drawings

Fig. 2 is the utility model discloses press flitch anti-drop and guider structure chart.

Detailed Description

Referring to fig. 2, the utility model discloses an anti-drop and guider includes: the device comprises a locking attachment block 15 which is fixed at the upper end of an upper die base 5 by a screw and is provided with an internal thread through hole, a core rod 8 which penetrates through the upper die base 5 and a pressure plate 6 and is assembled in a threaded hole of the locking attachment block through threads at the upper end, a tubular guide pillar 9 which is sleeved on the core rod 8 and penetrates through the upper die base 5 and the pressure plate 6, a guide sleeve 10 which is sleeved on the guide pillar 9 and is embedded in the guide pillar through hole of the pressure plate 6, a limiting block 11 which is sleeved on the end part of the core rod, extending out of the lower side surface of the pressure plate 6, of the core rod, an adjusting sleeve 12 which is arranged between the limiting block. The guide sleeve 10 is in sliding fit with the guide post 9, and the guide sleeve 10 is fastened on the pressure plate 6 through a screw 16 at the interface of the pressure plate 6.

Claims

1. The utility model provides a spacing guider of pressure flitch on last die holder, characterized by: the device comprises a locking block fixed at the upper end of an upper die holder and provided with a threaded hole, a core rod which penetrates through the upper die holder and a pressure plate and is assembled on the threaded hole of the locking block through threads at the upper end, a tubular guide pillar which is sleeved on the core rod and penetrates through the upper die holder and the pressure plate, a guide sleeve which is sleeved on the guide pillar and is embedded in a through hole of the guide pillar of the pressure plate, a limiting block which is sleeved on the end part of the core rod, extending out of the lower side face of the pressure plate, of the core rod, a nut which is assembled at the lower.
