Abstract

The utility model discloses an improved upper die ejector device of a spinning die, which comprises a disc spring (4), limit bolts (5) and an ejector block (6). The disc spring (4) is disposed between an upper die (1) and the ejector block (6) (the ejector block (6) is a movable part), the disc spring (4) constantly downwardly presses the ejector block which transmits force to a wheel workpiece (3), and automatic discharge is achieved. The ejector block is disposed on the upper die through the limit blocks, a product (3) can be effectively prevented from holding an upper die mandrel (2), and production efficiency is improved.

Description

Improved spinning upper mould Lifting Device
Technical field
The utility model relates to a kind of spinning mould of producing automotive hub.
Background technology
Forged hub is to finish through work steps such as forging, spinning.The wheel hub spinning upper mould structure of prior art as shown in Figure 1.Because wheel blanks 3 fronts are non-machined surface, for preventing that product 3 from rotating in process of production, patrix 1 need apply downward power to the centre and the outer rim position of wheel blanks 3, for preventing outer margin deformation, the measure of adopting is main stressed district for making wheel blanks 3 centres, thereby makes wheel blanks 3 centres produce plastic deformation, and 3 armfuls of generation wheel blanks are on patrix mandrel 2, cause demoulding difficulty, influence production efficiency.
The utility model content
The purpose of this utility model provides a kind of spinning upper mould of discharging automatically, enhances productivity.
The technical solution of the utility model is: a kind of spinning upper mould of discharging automatically, increased the patrix material jacking mechanism, comprise butterfly spring 4, caging bolt 5, ejection block 6, butterfly spring 4 are arranged between patrix 1 and the ejection block 6 (ejection block 6 for can movable parts), and 4 pairs of ejection block of butterfly spring remain downward power, by ejection block 6 is passed to wheel blanks 3 with power, reach the effect of automatic discharging; Caging bolt is arranged on ejection block on the patrix, and keeps certain activity space, plays the effect of restriction ejection block activity space size.
Advantage of the present utility model is: prevent that effectively wheel blanks from embracing on the patrix mandrel, enhance productivity.
Description of drawings
With the specific embodiment the utility model is described further in conjunction with the accompanying drawings.
Fig. 1 is a spinning upper mould structural representation in the prior art.
Fig. 2 is the utility model spinning upper mould Lifting Device schematic diagram.
Among the figure: 1-patrix, 2-patrix mandrel, 3-wheel blanks, 4-butterfly spring, 5-caging bolt, 6-ejection block.
The specific embodiment
As shown in Figure 2, the utility model spinning mould has increased Automatic Charging Device, comprise butterfly spring 4, caging bolt 5, ejection block 6, butterfly spring 4 are arranged between patrix 1 and the ejection block 6 (ejection block 6 for can movable parts), and 4 pairs of ejection block of butterfly spring remain downward power, by ejection block 6 is passed to wheel blanks 3 with power, reach the effect of automatic discharging; Caging bolt 5 is arranged on ejection block 6 on the patrix 1, and keeps certain activity space, plays the effect of restriction ejection block 6 activity space sizes.
In the production process, the improved spinning upper mould of the utility model Lifting Device can prevent effectively that 3 armfuls of wheel blanks from patrix mandrel 2, enhancing productivity.
The improved spinning upper mould of the utility model Lifting Device is not limited to the scheme that the drawings and specific embodiments are described, and the last mode structure of other Automatic Charging Device all falls into the scope of the utility model protection.
