Description

A kind of ring set class parts batch forges punching die

Technical field

The invention belongs to the fields of forging, and in particular to a kind of ring set class parts batch forges punching die.

Background technology

Ring set forging has wide application range in the industrial production, and middle ring type free forging refers mainly to forging Size meets 0.2（D-d）≤ H≤D classes, cover type free forging, refer mainly to forging's block dimension meet 0.1D≤H≤1.5D, d≤ 0.5D, ring set forging cover the petrochemical industries component such as the diesel engine parts such as gear ring, gear, cylinder cover, flange, head cover, bottom cover, The comprehensive mechanized coal minings equipment key part such as piston type, since operating mode is special, comprehensive mechanical performance requirement is high, except material particular/special requirement Outside, it is necessary to which forging is molded, of large quantities, it is desirable that high.Respectively a kind of general technological process of forging enterprise is in the market：Blanking-heating- Jumping-up-punching-upper saddle support tooling reaming-round as a ball flat end face, wherein reaming and flat end face need to operate repeatedly, will until reaching Seek size.The problem of being primarily present has the following：1）It is more due to expanding the flat process number of occurrence, increase fire, corresponding fire consumption increases, Increase heating cost；2）Efficiency is low, and labour cost is high, causes forging ton unit price of high cost；3）Due to open die forging workpiece, surface is deposited In hammer trace impression, it need to additionally increase surplus and ensure processing dimension.In order to shorten forging technology, one-pass molding reduces fire consumption, improves Efficiency ensures surface quality, reduces work pieces process surplus, improves product material utilization rate, current technique also promising blanking- Heating-jumping-up-die punching.This technique needs a kind of forging punching die, and general die cost is higher, and interchangeability is poor.

Utility model content

The purpose of this utility model be to provide it is a kind of efficiently, high yield, it is at low cost, be adapted to a variety of ring set specifications Ring set class parts batch forges punching die.

The purpose of this utility model is realized in the following manner：A kind of ring set class parts batch forges punching die, packet Punch and drain cap are included, upper mold is set on drain cap, upper mold contains internal diameter through-hole corresponding with ring cover parts outer diameter；It is set in upper mold Positioning disk, positioning disk contain the through-hole of internal diameter and punch major diameter fit；Drain cap pad is set on drain cap, and drain cap pad is located under upper mold Side, punch are corresponding with positioning disk inner via hole position.

Stepped hole is set on drain cap, and upper mold, drain cap pad are arranged on by stepped hole on drain cap.

Upper mold is upset mould.

The beneficial effects of the utility model are：The utility model is carried by upper mold, positioning disk, drain cap, drain cap pad and punch Punching die is forged for a kind of efficient, high yield ring set class parts batch, interchangeability is good, reduces the cost of forging, ensures Product quality.

Description of the drawings

Fig. 1 is the utility model principle schematic diagram.

Wherein, 1 is punch, and 2 be positioning disk, and 3 be upset mould, and 4 be drain cap pad, and 5 be drain cap

Specific embodiment

As shown in Figure 1, a kind of ring set class parts batch forging punching die, including punch 1,1 lower section of punch sets upper mold, The upset mould 3 used in upsetting process may be used in upper mold, have on upset mould 3 diameter it is upset with ring set forging after outer diameter it is identical Through-hole, 3 the inside setting positioning disk 2 of upset mould, setting diameter is slightly larger than the through-hole of punch outer diameter on positioning disk 2.Under upset mould 3 Side sets drain cap 5, sets stepped hole on drain cap 5, the diameter of stepped hole is reduced successively from top to bottom, and upset mould 3 is placed in drain cap 5 The uppermost hole of stepped hole on, drain cap pad 4 on second hole of the stepped hole of drain cap 5 is set, taper hole is set on drain cap pad 4, Taper hole upper diameter is small, following diameter is big.4 upper surfaces are padded with drain cap and are contacted in upset 3 lower face of mould.Upset mould 3 is exactly ring set class Mold of the forging Jing Guo upset process, mainly for cost-effective and time or the mold that is specifically manufactured.

When it is implemented, upset mould 3, is then placed in drain cap 5 by the upset molding inside upset mould 3 of ring set forging On, positioning disk 2 compresses ring set forging, is positioned with this.Upset 3 lower section setting drain cap pad 4 of mould.It is forged by punch 1 in ring set class Punching above part, punching core material are leaked out from drain cap.Ring set forging is controlled by controlling the height of punch 1 and upset mould 3 Highly, the internal diameter of ring set forging is controlled by positioning disk 2 and punch 1.

Using the utility model structure punching, 1-2 fire fire consumption is reduced, ensures a fiery one-pass molding, cost savings 2%- 4%；Efficiency compared to before, improve 2-3 times, manufacture cost accordingly reduce by half more than；Substantially reduce allowance, more than each machined surface Amount can ensure to be no more than 2mm；Forging any surface finish is smooth, accurate size；Mold has extremely strong interchangeability, and one module multiple usages can Cover the ring set forging of multiple specifications.The utility model had both reduced the cost of forging, in turn ensured product quality.
