Description
Technical field
The invention belongs to metal molding field, a kind of warm forging grinding tool guide frame for taking dnockout is more particularly to.
Background technology
Warm forging extends as the one kind in cold-forging technique field, the increasing large deformation being difficult to for cold-forging technique
The forging of amount.Because of expanding with heat and contract with cold for material, warm forging instead squeezes product and the anti-crowded drift phenomenon of bag easily occurs during the material returned,
And conventionally dnockout structure and guide frame conflict, it is impossible to meet production and quality requirement.
The content of the invention
Beaten it is an object of the invention to provide a kind of taking for phenomenon that can effectively solve the anti-crowded anti-crowded drift of forging bag of warm forging
The Warm Forging Die guide frame of material.
According to an aspect of the invention, there is provided a kind of Warm Forging Die guide frame for taking dnockout, including upper bolster,
Die shoe and spray dnockout component,
The upper bolster is provided with anti-crowded drift and the cavity for accommodating knockout rod, and the die shoe is provided with instead to be squeezed with described
The cavity that drift is engaged, the spray dnockout component includes connecting seat and the spray ring being fixedly connected on the connecting seat
With dnockout ring, the spray ring is located at the upper end of the dnockout ring,
The knockout rod includes first body of rod and second body of rod, and the diameter of first body of rod is more than second body of rod
Diameter, the cavity includes the first cavity and the second cavity, and the aperture of first cavity is more than the aperture of second cavity,
The aperture of first cavity is more than the diameter of first body of rod, and the aperture of second cavity is less than first body of rod
Diameter, the aperture of second cavity is more than the diameter of second body of rod, end and the company of second body of rod of the knockout rod
Joint chair is fixedly connected,
When the anti-crowded drift is run up away from the die shoe, the spray dnockout component pushes down the workpiece extremely
The workpiece is completely disengaged from the anti-crowded drift, when the knockout rod is walked in the cavity up to first body of rod
Bottom and the tangential of second cavity, the upper bolster drive the spray dnockout component upward by the knockout rod
It is mobile the spray dnockout component is separated with the die shoe.
In some embodiments, the anti-crowded drift is fixedly connected with the upper bolster by instead squeezing drift set.
In some embodiments, the knockout rod be arranged in parallel with the anti-crowded drift.
In some embodiments, the connecting seat is provided with guide rod, and the upper bolster is provided with pilot hole, described to lead
It is located in bar in the pilot hole.
In some embodiments, guide sleeve is provided with the die shoe, the guide sleeve is located in the cavity and institute
State anti-crowded drift and think contact.
Its advantage is：During anti-squeeze, anti-crowded anti-crowded drift is pushed, and three dnockout pawls of dnockout ring are placed in anti-squeeze
Inside anti-crowded drift, the anti-guiding instead squeezed between drift and guide sleeve of squeezing is not influenceed to coordinate, it is ensured that the jump of anti-crowded blank during extruding
Dynamic precision.
During the material returned, anti-crowded drift is enclosed in the presence of the upper bolster of forcing press, drives anti-crowded anti-crowded drift up,
Provided with the gap that length is L between knockout rod and upper bolster, in the range of upper bolster movement L, weight of the dnockout ring in spray ring
Under power effect, it is parked on lower moulded board, forging can not pass through, departs from anti-crowded anti-crowded drift, reach that discharging is acted on, upper bolster movement
After L distance, knockout rod drives and moved on spray ring and dnockout ring, departs from lower moulded board, the production of next blank is not influenceed.
The present invention can effectively solve the phenomenon that forging bag drift is instead squeezed in warm forging, it is ensured that forging quality requirement, improve life
Produce efficiency.
Brief description of the drawings
Fig. 1 is a kind of structural representation of Warm Forging Die guide frame for taking dnockout of an embodiment of the present invention；
Fig. 2 is Fig. 1 dnockout ring and instead squeezes the structural representation that drift is engaged.
Embodiment
Fig. 1 and Fig. 2 schematically show that the Warm Forging Die for taking dnockout of one embodiment of the present invention is oriented to knot
Structure.As depicted in figs. 1 and 2, the Warm Forging Die guide frame for taking dnockout includes upper bolster 2, die shoe 8 and spray dnockout group
Part.
Upper bolster 2 is provided with anti-crowded drift 4 and the cavity for accommodating knockout rod 1.Specifically, anti-crowded drift 4 and upper bolster 2
It is fixedly connected by drift set 3.Make instead to squeeze drift 4 and upper bolster 2 is connected firmly.Knockout rod 1 includes first body of rod and the second bar
Body.The diameter of first body of rod is more than the diameter of second body of rod.Knockout rod 1 be arranged in parallel with the anti-drift 4 that squeezes.It is easy to instead squeeze drift 4
With moving up and down for knockout rod 1.Cavity includes the first cavity and the second cavity.The aperture of first cavity is more than the hole of the second cavity
Footpath.The aperture of first cavity is more than the diameter of first body of rod.The aperture of second cavity is less than the diameter of first body of rod.Second cavity
Aperture be more than second body of rod diameter.Spray dnockout component includes connecting seat and the spray ring being fixedly connected on connecting seat
6 and dnockout ring 5, spray ring 6 is located at the upper end of dnockout ring 5.The end of second body of rod of knockout rod 1 is fixedly connected with connecting seat.
Connecting seat is provided with guide rod, and upper bolster 2 is provided with pilot hole, and guide rod is located in pilot hole.Play a part of guiding, make
The orientation moved up and down of anti-crowded drift 4 is more accurate.Die shoe 8 is provided with squeezes the cavity that drift 4 is engaged with anti-.In die shoe
Provided with guide sleeve 7, guide sleeve 7 is located in cavity to be wanted to contact with the anti-drift that squeezes.When anti-crowded drift is moved up or down, guide sleeve
7 pairs its there is guide effect.
When anti-crowded drift 4 is run up away from die shoe 8, spray dnockout component pushes down workpiece to workpiece and anti-crowded drift
4 completely disengage from, when knockout rod 1 walks bottom and the tangential of the second cavity until first body of rod, upper bolster 2 in cavity
Driving spray dnockout component to move up by knockout rod 1 makes spray dnockout component be separated with die shoe 8.
During anti-squeeze, anti-crowded anti-crowded drift 4 is pushed, and three dnockout pawls of dnockout ring 5 are placed in anti-squeeze in anti-crowded drift 4
Portion, does not influence the anti-guiding instead squeezed between drift 4 and guide sleeve 7 of squeezing to coordinate, it is ensured that the bounce precision of anti-crowded blank during extruding.
During the material returned, drift set 3 drives anti-crowded anti-crowded drift 4 up in the presence of the upper bolster 2 of forcing press,
Provided with the gap that length is L between knockout rod 1 and upper bolster 2, in the range of the movement of upper bolster 2 L, dnockout ring 5 is in spray ring 6
Action of Gravity Field under, be parked on lower moulded board, forging can not pass through, depart from it is anti-squeeze anti-crowded drift 4, reach that discharging is acted on, upper mould
Seat 2 is moved after L distance, and knockout rod 1 drives spray ring 6 and dnockout ring 5 to move upwards, is departed from lower moulded board, is not influenceed next
The production of blank.
The above is only some embodiments of the present invention.For those skilled in the art, the present invention is not being departed from
On the premise of creating design, various modifications and improvements can be made, these belong to protection scope of the present invention.
