Description

Circular die holder

Technical field

The utility model relates to a kind of part of metal forming machinery, particularly relates to a kind of forging die or its installation.

Background technology

In the forging field, in order to realize forging process, generally to use mould, present mould is all made by mould steel basically, if forging is of a great variety, then needs corresponding various forging designing mould respectively, sometimes also designs many molds possibly.The cost that removes to design and make a mold at various forging separately is very high, and the material of consumption is more, and its process-cycle of blank of making mould also long, processing capacity is bigger, so not only uneconomical, enhance productivity nor be beneficial to.At present, the die holder that embedded fixed mould is also arranged in the forging field, be 200620167519.X as application number, Granted publication number is CN201023123Y, Granted publication day is the disclosed a kind of forging die all round die holder of the Chinese utility model patent on February 20th, 2008, it will process dovetail in the chamber of die holder, corresponding mould also will be processed dovetail, cause the process-cycle of mould longer like this, reduced production efficiency, in addition, forging is also various, as major axis, minor axis, the bar class, square, shaped piece, circular piece etc., the each have their own characteristics of its shape, the die holder inner chamber of arbitrary shape can not be applicable to various forging fully.

The utility model content

The technical problems to be solved in the utility model provides a kind of circular die holder that can reduce the Mould Machining cycle, enhance productivity, be applicable to circle and bar forging.

The circular die holder of the utility model, it comprises die shoe and upper bolster, described upper bolster be positioned at die shoe directly over, upper edge, the lower surface fore-and-aft direction of described die shoe is provided with the die shoe dovetail, be provided with the following impression chamber of upper end open in the die shoe, following impression chamber is rounded, be provided with die shoe in the die shoe and eject the hole, die shoe ejects hole and following impression chamber coaxial line, be provided with the open loop boss in the described periphery in impression chamber down on the upper surface of die shoe, the breach of described open loop boss is positioned at the right front in impression chamber down, be provided with die shoe drift jack along fore-and-aft direction in the die shoe, die shoe drift jack is positioned at described right side and the die shoe drift jack in impression chamber down and is connected with following impression chamber, is inserted with hyposphene iron in the die shoe drift jack;

Upper edge, the upper surface fore-and-aft direction of described upper bolster is provided with the upper bolster dovetail, be provided with the last impression chamber of lower ending opening in the upper bolster, last impression chamber is rounded, last impression chamber and described impression chamber coaxial line down, be provided with upper bolster in the upper bolster and eject the hole, upper bolster ejects hole and last impression chamber coaxial line, on the lower surface of upper bolster on described the periphery in impression chamber be provided with annular groove, annular groove is corresponding with described open loop boss, also be provided with flash gutters on the lower surface of upper bolster, flash gutters is corresponding with the breach of described open loop boss, flash gutters is connected with described annular groove, be provided with upper bolster drift jack along fore-and-aft direction in the upper bolster, upper bolster drift jack is positioned at described right side and the upper bolster drift jack of going up the impression chamber and is connected with last impression chamber, is inserted with drift in the upper bolster drift jack.

The circular die holder of the utility model, the left side central portion position of wherein said upper bolster dovetail is provided with keyway, and the left side central portion position of described die shoe dovetail is provided with down keyway.

The circular die holder of the utility model, be equipped with a vertical hole for hoist of die shoe on the front end face of wherein said die shoe and the rear end face, be equipped with two horizontal holes for hoist of die shoe on the left side of described die shoe and the right side, be equipped with a vertical hole for hoist of upper bolster on the front end face of described upper bolster and the rear end face, be equipped with two horizontal holes for hoist of upper bolster on the left side of described upper bolster and the right side.

The circular die holder difference from prior art of the utility model is that the circular die holder of the utility model adopts the upper bolster and the die shoe that have circular impression chamber to cooperate drift to come the clamping mould, the mould of clamping only needs processing cavity, need not process dovetail and keyway, can save the mould steel more than 50%, the cycle of processing is short, can enhance productivity, economic benefit is obvious, because the shape in impression chamber is rounded, so the circle of being applicable to and bar forging, open loop boss and annular groove have been used for leading and the effect in jig gap in the circular die holder of the utility model, the breach of open loop boss can be worked as the base platform, upper bolster ejects hole and die shoe and ejects the hole and be used for ejecting and dismantle mould in the impression chamber of packing into, and drift is used for mold cramping is fixed.

The left side central portion position of upper bolster dovetail is provided with keyway in the circular die holder of the utility model, when the left side central portion position of die shoe dovetail is provided with down keyway, when installing die holder and die shoe, can insert key respectively in last keyway and the following keyway and be used for limiting moving forward and backward of upper bolster and die shoe; Be equipped with a vertical hole for hoist of die shoe on the front end face of die shoe and the rear end face in the circular die holder of the utility model, when being equipped with the horizontal hole for hoist of two die shoes on the left side of die shoe and the right side, two vertical holes for hoist of die shoe are used for the lifting die shoe, four horizontal holes for hoist of die shoe are used for handling die shoe when heat treatment, similarly, the hole for hoist of upper bolster also plays the effect that makes things convenient for the handling upper bolster.

Below in conjunction with accompanying drawing the circular die holder of the utility model is described further.
