Description
Technical field
The present invention relates to a kind of ejecting mechanism, and in particular to a kind of ejecting mechanism for necking part on crank press,
Belong to machining technology field.
Background technology
One part of certain product, formed with steel pipe by necking post-processing, necking process is needed in crank press
Completed on machine, after part necking, there is one section of cylindrical section lower end, and this section of diameter holds its shape constant, and upper end edge axis vertical is cast aside
To be parabola shaped, necking port part internal diameter is about 30mm, and a part for parabolical whole and lower end cylindrical section is contained in necking
In mould, it is impossible to which voluntarily abjection is, it is necessary to which a kind of mechanism ejects from the top down, for crank press except top shoe has one to beat
Expect outside thick stick, be not provided with the ejecting mechanism for the various processes such as necking, it is necessary to according to process needs, configure a set of head part in addition
Mechanism, the work of the complete cost procedure of ability.Due to currently without can be by after the necking of tubular articles upper end, by necking part in necking
The mechanism that the top of mould ejects out of mold cavity, inconvenience is brought to this kind of part removal of the steel pipe after necking.
The content of the invention
The invention aims to solve currently without can be by after the necking of tubular articles upper end, by necking part in necking
The mechanism that the top of mould ejects out of mold cavity, asking for inconvenience is brought to this kind of part removal of the steel pipe after necking
Topic.And then provide a kind of ejecting mechanism for necking part on crank press.
The technical scheme is that：A kind of ejecting mechanism for necking part on crank press includes spring return type
Push rod component and suspension head part thick stick, suspension head part thick stick are arranged in spring return type push rod component,
Spring return type push rod component includes head part bar, back-moving spring and head part thick stick；Head part bar carries flange for centre
Cylinder, head part bar can be slid through in the sliding block center vertical direction counterbore on crank press, and back-moving spring is sleeved on top
The flange lower end for being located at head part bar is supported in the bottom of part bar, the upper end of back-moving spring, and the lower end of back-moving spring, which is stuck among sliding block, erects
To on counterbore, the upper end of head part bar contacts Nogata with head part thick stick；
Suspension head part thick stick includes two groups of suspension head part thick sticks, and two groups of suspension head part thick sticks are sleeved on head part thick stick, every group of head part
Thick stick includes head part lever bracket frame, limited block, bolt, nuts and washers, and head part lever bracket frame is channel-shaped carrier, and head part lever bracket frame is enclosed on
On head part thick stick, limited block is arranged on the upper end of head part lever bracket frame by connector, and the limited block upper end of every group of head part thick stick passes through
Bolt, nuts and washers and crank press connect.
The present invention has the following effects that compared with prior art：
For necking part, the lower end of head part bar can not be contained in the necking course of work in mould necking die cavity, if
Head part bar is contained in mould necking die cavity in the necking course of work, then head part bar is tightly contained at necking by necking part, it is impossible to is pulled out
Go out, can not more carry out head part work, therefore, head part bar should exit the top of mold cavity in the necking course of work, in necking
After the completion of work, head part bar is in the presence of head part thick stick, and by the downward ejection die die cavity of necking part, head part bar should exit mould afterwards
Have die cavity, need spring to reset head part bar upwards for this, design necking part ejecting mechanism on a kind of crank press accordingly.This
The ejecting mechanism of invention makes head part bar automatically reset in the presence of back-moving spring, and head part bar can be prevented by the work after necking
Part chokes；In the presence of whole mechanism, the necking part for getting into necking die die cavity can from top to bottom be ejected, prevent necking
Part is squeezed in necking die die cavity, it is impossible to the generation of continuous necking work problem, realizes that workpiece necking is smoothed out.
The present invention is simple in construction, is easy to manufacture, cost is cheap.
