The present embodiment additionally provides a kind of pressing method, please refers to the stream pressurizing unit structure chart of Fig. 1, this is discussed in detail
The implementation steps of pressing method:
Current equalizer 100 is set in cylinder 200, and when current equalizer 100 is in original state, the first support division 02, second are supported
It holds portion 03 and third support division 04 is not on same plane close to the side of bottom wall 300, and stepped setting, specifically
, third support division 04 close to 300 sides of bottom wall closest to bottom wall 300, the first support division 02 close to the side of bottom wall 300 away from
Farthest from bottom wall 300, multiple second support divisions 03 are close to the distance of a lateral extent bottom wall 300 of bottom wall 300 by third support division
04 becomes larger to the direction of the first support division 02.
In cylinder 200, material to be extruded is filled between bottom wall 300 and current equalizer 100.After extruding starts, flow
Device 100 is moved by original state along first direction x, i.e., along cylinder 200 it is axial along by current equalizer 100 towards the direction of bottom wall 300
Movement, piston 01 support ring 12 and support the first support division 02 close to one end of piston 01, make first to support under the drive of external force
Portion 02 is moved along first direction x.The first elastic component 05 between first support division 02 and the second support division 03 generates sufficiently large
Elastic force, to drive the second support division 03 mobile, so that the second support division 03 is also moved along first direction x.Similarly, it second supports
The second elastic component 06 held between portion 03 and third support division 04 generates sufficiently large elastic force, to drive third support division 04 to move
It is dynamic, so that the second support division 03 is also moved along first direction x.
First support division 02, the second support division 03 and third support division 04 move closer to bottom wall 300, when the final shape of arrival
When state, the first support division 02, the second support division 03 and third support division 04 are in same plane close to one end of bottom wall 300
On.During the entire process of being extruded, the material positioned at 200 middle part of cylinder is extruded first, this partial material can expand to surrounding
It dissipates, and the space being gradually filled between current equalizer 100 and material, after the space has been padded, the material in cylinder 200 just exists
Under the continuing to press on of current equalizer 100, uniformly squeezed out from extruded hole 310.In whole process, due to the hysteresis of elastic force,
The distance that different support divisions are moved to bottom wall 300 and speed difference, in this way, it is ensured that squeezed out on bottom wall 300 from extruded hole 310
Material is uniform.In addition, haveing suffered in extrusion process, the guide rod 41 of third support division 04 can move in the second through-hole 14,
The first guide table 42 is avoided to support in the junction of first through hole 13 and the second through-hole 14.
When current equalizer 100 is returned to original state movement by end-state, i.e., y is moved current equalizer 100 in a second direction,
Piston 01 makes to support the first support division 02 of disengaging of ring 12 under the drive of external force, and the first guide table 42 moves closer to first through hole 13
With the junction of the second through-hole 14, and finally support at this.At this moment, piston 01 drives third support division 04 along second party first
It is moved to y.It is supported by elastic connection between third support division 04 and the second support division 03 and the second support division 03 with first
Hold the elastic connection between portion 02, third support division 04 drives the second support division 03 and the first support division 02 together in a second direction
Y movement.
Stop applying external force after piston 01 returns to the position of original state, due to third support division 04 and the second support division
Elastic connection is carried out by the first elastic component 05 between 03, passes through the second elasticity between the second support division 03 and the first support division 02
Part 06 carries out elastic connection, so the second support division 03 and the first support division 02 can continue edge under the action of elastic component elastic force
Second direction y moves a distance, in this way, the first support division 02 and the second support division 03 are returned to the position under original state again
It sets.This process is recycled, can realize the continuous extruding to material in cylinder 200.
It is provided in this embodiment stream pressurizing unit have the following the utility model has the advantages that
A kind of stream pressurizing unit is present embodiments provided, which supports
Portion 02, the second support division 03 and third support division 04 mark off different material crush-zones, the first support division 02 and
Different material crush-zone is realized between two support divisions 03, between the second support division 03 and third support division 04 by elastic connection
Extruding movement, the quality for the material that can effectively ensure that the uniform of material flow, and squeeze out meets the requirement of subsequent blank.
Different quantity can be set as needed in second support division 03, and it is more careful in this way to divide crush-zone, right
It answers, the quantity and density of extruded hole 310 are increase accordingly, and keep the material squeezed out more uniform, more efficient.Different support divisions
Between by the first elastic component 05 and the second elastic component 06 come the mutual transmitting of retentivity, guarantee current equalizer 100 can complete by
Original state arrives the circulation action of original state, the smart structural design of entire current equalizer 100 to squeezed state again, and is easy to manage
Solution and operation.
Using the pressing method that can be applied to flow pressurizing unit provided in embodiment, effectively material can be squeezed out
Molding meets requirement of the production to quality of material.
