Embodiment Construction

[0025] The present invention will be further described below in conjunction with embodiment (accompanying drawing):

[0026] The mechanism of the present invention, which is suitable for off-line rapid mold change of multi-station cold heading machines, includes two parts: a movable mold and a fixed mold.

[0027] Such as figure 1 , 2 , 3, the fixed mold part of the present invention includes the fixed mold base 1 of the cold heading machine, and the fixed template block 2 installed in the step-shaped notch provided on one side of the fixed mold base 1 of the cold heading machine. The horizontal hydraulic cylinder 6 of the fixed template for pulling the fixed template block 2 to realize the clamping and positioning of the fixed template block 2 in the horizontal direction is installed between the side elevations of the mold base 1 and the fixed template block 2. The vertical hydraulic cylinder 5 of the fixed template for pulling the fixed template block 2 to realize the clam...

Abstract

The invention relates to a mechanism suitable for off-line quick die change of a multistage cold former. The mechanism comprises a moving die and a fixed die. The fixed die part comprises a cold former fixed die seat and a fixed die plate module; a horizontal hydraulic cylinder for clamping and positioning in the horizontal direction is arranged between the matched side vertical faces of the cold former fixed die seat and the fixed die plate module; a vertical hydraulic cylinder for clamping and positioning in the vertical direction is arranged between the matched base planes of the cold former fixed die seat and the fixed die plate module; both matched ends of the cold former fixed die seat and the fixed die plate module are respectively provided with a lateral regulating plunger type cylinder; the moving die part comprises a cold former moving die seat, a moving die plate base board and a moving die plate assembly; a horizontal hydraulic cylinder for clamping and positioning in the horizontal direction is arranged between the matched side vertical faces of the cold former moving die base board and the moving die plate module; a vertical hydraulic cylinder for clamping and positioning in the vertical direction is arranged at the top of the moving die plate base board.

Description

technical field [0001] The invention belongs to a mechanism for off-line mold change in the machinery manufacturing industry, and in particular relates to a mechanism suitable for off-line rapid mold change of a multi-station cold heading machine. Background technique [0002] During the production process of the multi-station cold heading machine, it is necessary to replace the old and new molds or to replace the molds of different product models, so the number of molds is large and the frequency of replacement is very high. The existing mold replacement method is to disassemble the mold from the cold heading machine body, then use manual and general lifting tools to drag the mold out of the working area of ​​the press, and then drag the mold of the next workpiece into it. The traditional cold heading machine mold lock adopts multiple bolts to lock and position the bed, loading and unloading the mold is more cumbersome, and the precision is poor. Processing time for econom...
