Abstract

The invention relates to the field of a motor punching sheet double punching mold, in particular to a female mold split block assembly of a large-scale double punching mold. The female mold split block assembly comprises a female mold split block and a fixing device, wherein the fixing device comprises a fixing plate, the female mold split block is fixedly arranged on the fixing plate through a plurality of screws, the fixing device also comprises a hoop, a low-melting-point alloy layer and a plurality of regulating screws, the hoop is arranged on the outer periphery of the female mold split block, the low-melting-point alloy layer is arranged between the female mold split block and the hoop, the hoop is fixedly arranged on the fixing plate through the screws, and the regulating screws pass through the hoop and the low-melting-point alloy layer from outside to inside in the radial direction until the bottoms of the regulating screws are tightly pasted with two ends of the outer side of the single female mold split block. The female mold split block assembly of the large-scale double punching mold has the characteristic that the female mold split block assembly can be respectively processed on a plurality of ordinary machine tools, the time is effectively saved, the work efficiency is improved, the requirement on processing equipment is not high, and the maintenance is convenient through the arrangement of the low-melting-point alloy layer.

Description

Large-scale multiple punch die tool cavity splits assembly
Technical field
The present invention relates to the multiple punch die tool field of a kind of motor stamping, specifically is a kind of large-scale multiple punch die tool cavity splits assembly.
Background technology
At present; Large-scale multiple punch die tool cavity splits assembly (like Fig. 1, shown in 2) comprises cavity splits 1 and fixture; Described fixture comprises hot jacket 2 and fixed head 3; Described hot jacket 2 interference fit are in the periphery of cavity splits 1, and described cavity splits 1 is fixed on the fixed head 3 through some screws 4.The defective that this cavity splits assembly exists is: one, processing charges is higher: add man-hour, if the appearance and size of whole cavity splits 1 is bigger, must could process at the big lathe of stroke in electric machining (silk of being careful) time, the lathe expense that stroke is big is higher; Two, the range of work is limited: add man-hour; Hot jacket 2 and cavity splits 1 are always become a useful person and can be processed whole cavity splits 1 for interference fit and the bigger characteristics of stress have determined to assemble cavity splits; If the appearance and size of whole cavity splits 1 surpasses machine tool travel; Just can't accomplish whole machining process by a clamping, the precision of cavity splits 1 does not guarantee; If the single cavity splits 1 of processing refills and prepares the cavity splits assembly earlier by force, will cause cavity splits 1 distortion like this, precision does not guarantee more; Three, size is difficult to control: because the Stress Release of hot jacket 2 is incomplete, the dimension overproof of cavity splits 1 can't be adjusted; Four, maintenance load is bigger: in the concrete stamping-out use, when problematic single or a plurality of piece occurring, must whole cavity splits assembly all be dismantled, just can keep in repair.
To sum up tell, because there is a large amount of defectives in existing large-scale multiple punch die tool cavity splits assembly, so be necessary to work out a kind of novel cavity splits assembly.
Summary of the invention
The present invention provides a kind of large-scale multiple punch die tool cavity splits assembly in order to remedy the defective that existing cavity splits assembly exists.
The present invention realizes through following technical scheme: a kind of large-scale multiple punch die tool cavity splits assembly; Comprise cavity splits and fixture; Described fixture comprises fixed head, and described cavity splits is fixed on the fixed head through some screws, and described fixture also comprises the hoop of the periphery of being located at cavity splits; Be located at the low-melting alloy layer between cavity splits and the hoop, some adjustment screw; Described hoop is fixed on the fixed head through some screws, and described adjustment screw radially is close to the two ends, the outside of single cavity splits from outside to inside until the screw rod bottom of adjustment screw through hoop and low-melting alloy layer.
During concrete the use, can guarantee the dimensional accuracy of cavity splits through regulating the size of radially adjusting single cavity splits from outside to inside through the adjustment screw of hoop and low-melting alloy layer.
The cavity splits of traditional large-scale multiple punch die tool cavity splits assembly and fixture assemble and just allow whole processing cavity splits; Large-scale multiple punch die tool cavity splits assembly of the present invention can be processed single cavity splits earlier, refills and prepares cavity splits and fixture.Because the size of single cavity splits is less, its range of work no longer receives the restriction of machine tool travel, can on a plurality of machine tools, process respectively, saves time effectively, increases work efficiency, and has reduced processing charges; When problematic single cavity splits occurring, only need heating burn the low-melting alloy layer, keep in repair with regard to dismountable problematic cavity splits.Described low-melting alloy layer has the cold characteristic that rises of pyrocondensation, and its characteristic is those skilled in the art's a common practise.
When large-scale multiple punch die tool cavity splits assembly of the present invention has changed traditional large-scale multiple punch die tool cavity splits structure; Also changed the processing mode of cavity splits; Cavity splits assembly of the present invention is convenient to the adjustment of cavity splits size, can be on a plurality of machine tools respectively machining characteristics effectively practiced thrift the time, improved operating efficiency; Less demanding to process equipment, being arranged so that of low-melting alloy layer is easy to maintenance.

The specific embodiment
A kind of large-scale multiple punch die tool cavity splits assembly; Comprise cavity splits 1 and fixture; Described fixture comprises fixed head 3, and described cavity splits 1 is fixed on the fixed head 3 through some screws 4, and described fixture also comprises the hoop 5 of the periphery of being located at cavity splits 1; Be located at the low-melting alloy layer 7 between cavity splits 1 and the hoop 5, some adjustment screw 8; Described hoop 5 is fixed on the fixed head 3 through some screws 6, and described adjustment screw 8 radially is close to the two ends, the outside of single cavity splits 1 through binding round 5 with low-melting alloy layer 7 from outside to inside until the screw rod of adjustment screw 8 bottom.
Described adjustment screw 8 is a soket head cap screw, is convenient to the inner hexagonal hole that specific purpose tool inserts soket head cap screw, adjusts the dimensional accuracy of cavity splits 1.
