Abstract

The utility model provides a molding device for special-shaped reinforcing ring used for molding various kinds of special-shaped reinforcing rings simply, quickly and accurately. A supporting punch is arranged on a major pressing head of the upper portion of a hydraulic engine. A left pressing head and a right pressing head are respectively arranged on two sides of the hydraulic engine. A supporting ring is fixed on an operation platform of the hydraulic engine. A left die and a right die are respectively arranged on the left pressing head and the right pressing head. A front sliding terrace die, a back sliding terrace die, a left gliding terrace die and a right gliding terrace die are connected with a return spring of a gliding terrace die. The return spring of the gliding terrace die is fixed in a spring pilot hole. Due to the fact that the material is forged by heating, the organizing structure of the materials is changed, the mechanical strength and performance are greatly improved, the sand inclusion and air holes in the inner portion of the components are avoided. The molding device for special-shaped reinforcing ring is capable of molding the special-shaped reinforcing rings with different shapes and sizes. The production cost is greatly reduced and production efficiency is improved.

Description

The shaped device of abnormity stiffening ring

Technical field

The utility model relates to the Machining Technology field, specifically a kind of device of moulding abnormity stiffening ring.

Background technology

Usually, punching weldering axle housing all need adopt stiffening ring, the shape of stiffening ring has circular, but abnormity is also arranged.Circular stiffening ring manufacturing is very simple, only needs the material heating is rolled over and is forged into annular blank spare, then gets final product through lathe machine-shaping, and its stock utilization is more than 70%.

Yet just there is certain difficulty in special-shaped stiffening ring in manufacture process, and its manufacture method has two kinds, the one, directly adopt the line patterning method at steel plate, can obtain the high part of dimensional accuracy, but stock utilization and work efficiency are all quite low, are difficult to reach the volume production requirement, and manufacturing cost is high; The 2nd, adopt casting method, although effective molded blank spare except the processing of need lathe, also need increase the milling machine manufacturing procedure in the part machining process, working (machining) efficiency is too late circular stiffening ring far away; In addition, the most important thing is that cast member is difficult to guarantee that cast blank spare inside without burning into sand and pore, in case there are the casting flaws such as burning into sand and pore, will cause the quality risk that whole axle housing is scrapped because of the leakage of oil of axle housing gear-box.

Summary of the invention

For overcoming the deficiency that existing special-shaped stiffening ring processing cost is high, work efficiency is low, goal of the invention of the present utility model is to provide a kind of shaped device of special-shaped stiffening ring, with the purpose of the special-shaped stiffening ring of realizing fast, accurately processing various difformities and size.

For achieving the above object, hydraulic press of the present utility model top is equipped with on the main pressure head and is shored drift, and side pressure head and right side pressure head are contained in respectively the both sides of hydraulic press, and filler ring is fixed on the workbench of hydraulic press; Left side die and right side die are contained in respectively on left side pressure head and the right side pressure head; Front slide punch, rear slip punch, left slip punch, right slip punch in the filler ring are connected with slip punch return spring respectively, and slip punch return spring is fixed in the bullet ring pilot hole on the filler ring.

When making special-shaped stiffening ring, with the raw material heating, roll over and be forged into annular blank spare first, then the blank Vehicle Processing is become required semi-finished product, again semi-finished product are put into shaped device, be pressed into needed special-shaped stiffening ring finished product.

The utility model compared with prior art, the special-shaped stiffening ring that adopts the utility model to make, because of material through the heats forged moulding, change has occured in the material metallurgical structure, mechanical strength and performance are improved significantly, and do not have the sightless burning into sand of inside parts and pore hidden danger, can convenient and swift, accurately process the special-shaped stiffening ring of various difformities and size, greatly reduce production cost, improved production efficiency.

The specific embodiment

Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, be equipped with on the main pressure head 12 on hydraulic press top and shore drift 9, left side pressure head 10 and right side pressure head 11 are contained in respectively the both sides of hydraulic press, and filler ring 7 is fixed on the workbench of hydraulic press; Left side die 1 is contained in respectively on left side pressure head 10 and the right side pressure head 11 with right side die 2; Front slide punch 3, rear slip punch 4, left slip punch 5, right slip punch 6 in the filler ring 7 are connected with slip punch return spring 8 respectively, and slip punch return spring 8 is fixed in the bullet ring pilot hole on the filler ring.

The utility model is when processing profiled stiffening ring; first semi-finished product 13 are placed on the filler ring 7; press the closed knob of hydraulic press; hydraulic press moves follow procedure automatically;

pressure head

10 and 11 while of right side pressure head move toward one another at first; be contained in left side die 1 and right side die 2 also while move toward one another on the pressure head; press to semi-finished product 13; this moment, main pressure head 12 pressed down; shore drift 9 and strut simultaneously front slide punch 3; rear slip punch 4; left slip punch 5; right slip punch 6 to assigned position stops; then main pressure head 12 up returns; front slide punch 3; rear slip punch 4; left slip punch 5; right slip punch 6 is self-return under the effect of slip punch return spring 8; left side pressure head 10 and right side pressure head 11 be return simultaneously; the operative employee can easily take out compressing special-shaped stiffening ring 14, and whole work flow only needs 30 seconds time.
