Stick is connected with rotary components and moving assembly, and rotary components can drive plug to move relative to workpiece rotation, and moving assembly can band
Dynamic plug is moved horizontally relative to workpiece.
A kind of punching press pickup method of stamped workpieces, comprising the following steps: upper mold is moved down to be contacted with lower die, upper mold
Punch assembly carries out punching press to the workpiece for being arranged with recess plug in lower die is located at, and the surface of workpiece is formed and plug recessed fit
Groove;Rotary components drive Mandrel Rotating to plug recess and work grooves discrete state;Moving assembly drives plug horizontal
Move away from workpiece;Upper mold, which moves up, drives punch-head assembly far from workpiece, takes out the workpiece that punching press is completed.
The advantages of punching press pick-off unit and pickup method of a kind of stamped workpieces of the invention, is: by moving assembly pair
Workpiece is rotated and is moved, and the workpiece for easily completing punching press takes out, and is saved labour, is improved work efficiency.
Specific embodiment
In order to be better understood by the purpose of the present invention, structure and function, with reference to the accompanying drawing, to a kind of punching press of the invention
The punching press pick-off unit and pickup method of workpiece do further detailed description.
As shown in Figure 1, its punching press pick-off unit for being shown as a kind of stamped workpieces of the invention, including upper mold 1 and lower die 2,
It is provided with the punch-head assembly 11 for stamped workpieces in upper mold 1, is provided with multiple formed punches in punch-head assembly 11, formed punch is vertically fixed
In upper mold 1, mobile upper mold 1 can drive formed punch to mobile close to the direction of workpiece, touch that continue to move to after workpiece can be to work
Part carries out punching press, and the blade plug 21 being set in workpiece 3 to be punched, plug and rotary components and movement are provided in lower die 2
Component is connected, and rotary components can drive plug relative to 3 rotary motion of workpiece, and moving assembly can drive plug relative to workpiece 3
It moves horizontally.
Further, rotary components and moving assembly are located in lower die 2, are each attached to the same end of plug 21, rotation group
Part includes the gear 25 being connected with plug 21, and gear 25 is meshed together with rack gear 24, and 24 rotate gear 25 of rack gear can drive
Plug 21 rotates, until plug recess with work grooves to separate.Moving assembly includes the sliding block 23 being connected with plug 21, sliding block 23
Plug 21 can be driven to move horizontally on guide rail 22, the plug extraction workpiece 3 after separating with work grooves is far from workpiece.Its
In, there is certain gap between the side surface/or other surfaces and workpiece of the plug 21, after which can accommodate molding
The groove of plug can smoothly take out workpiece after being rotated the groove of workpiece after molding to gap location with realization.Fig. 2 b and
Shown in Fig. 2 c, plug 21 is driven to be rotated by the gear 25 of moving assembly, rotatable 90 °, mobile sliding block 23 drives plug
Far from the workpiece that punching press is completed, as shown in Figure 2 d, 1 uplink of upper mold takes out workpiece and completes press work far from workpiece.
Further, the upper surface of plug 21 is provided with helical teeth shape recess, groove shapes needed for the shape and workpiece 3 of recess
Identical, at the same time, each nose of punch in the punch-head assembly 11 of upper mold 1 is provided with and 21 upper surface concave shape of plug
The protrusion to match, as shown in Figure 2 a, upper mold 1 and the molding of lower die 2 carry out press work, and punch-head assembly, which is displaced downwardly to, touches punching press
Punching press is carried out to workpiece when workpiece, workpiece surface is deformed in the recess for falling into plug 21 by the stamping press of punch-head assembly 11 and formed
Groove.
The invention also discloses a kind of pickup method of stamped workpieces, the step of now in conjunction with attached drawing to punching press pickup method into
Row explanation, punching press pickup step include:
As shown in Figure 2 a, first step, molding: upper mold 1 is moved down to be contacted with lower die 2, and the punch assembly 11 of upper mold is right
The workpiece 3 that recess plug 21 is arranged in lower die 2 carries out punching press, and the surface of workpiece 3 is formed and 21 recessed fit of plug
Groove.
As shown in Figure 2 b, second step, rotating mandrel: the rotary components in driving lower die, rotary components drive plug rotation
Go to plug recess and work grooves discrete state, wherein mobile band moving gear is carried out to the rack gear in rotary components and is rotated, is led to
Crossing gear drives Mandrel Rotating to separate with work grooves.
As shown in Figure 2 c, third step, mobile extraction plug: the moving assembly in driving lower die, moving assembly drive core
Stick is moved horizontally far from workpiece, wherein is moved to the sliding block in moving assembly, sliding block drives plug to move horizontally far from work
Part.
As shown in Figure 2 d, four steps is opened pickup: after punching press, upper mold, which moves up, drives punch-head assembly separate
Workpiece can be taken off the workpiece of punching press completion.
The punching press pick-off unit and pickup method of a kind of stamped workpieces of the invention, the workpiece that can easily complete punching press
It takes out, saves labour.
The present invention is further described by specific embodiment above, it should be understood that, here specifically
Description, should not be construed as the restriction for the essence of the present invention with range, and one of ordinary skilled in the art is reading this explanation
The various modifications made after book to above-described embodiment belong to the range that the present invention is protected.
