Description
Technical field
The present invention relates to punching die technical fields, more particularly, to a kind of transmission axis hole molding die.
Background technique
Transmission shaft is a kind of high revolving speed, the rotary body supported less, is widely used in power drive field, therefore for axis hole
Precision requirement it is relatively high, in axis hole forming process, expect mushroom head how easy to form, expect few to be easy cracking, Dan Danjin
Row punch operation is to be difficult to ensure the precision of axis hole, generally takes out hole again in axis hole.But in the prior art, for taking out hole
The step for power of a test it is smaller, the material for taking out hole often will form accumulation, influence axis hole shaping, it is difficult to guarantee product quality, work
Make low efficiency, cost input is big.
Therefore, to solve the above problems, the present invention provides a kind of new technical solutions.
Summary of the invention
The object of the present invention is to provide a kind of molding yield height, work efficiency is high and transmission axis hole molding at low cost
Mold.
Used technical solution is the present invention in view of the above technical defects：
A kind of transmission axis hole molding die, including upper die holder, punch retainer, stripper, punch-pin, cavity plate and lower die holder,
The punch retainer is mounted on the bottom of upper die holder by straight pin, and punch-pin, and punch-pin are equipped on the punch retainer
It is corresponding with the cavity plate on lower die holder across stripper, one group of stroke slotting tool, one group of stroke are symmetrically arranged on the upper die holder
The opposite face of slotting tool is provided with the first guiding incline, and the lower die holder is symmetrically arranged with one group of dressing stick in the two sides of cavity plate, and one group
Dressing stick is provided with the second guiding incline compatible with the first guiding incline, and the upper end of one group of dressing stick in the end face back to cavity plate
Face sliding is provided with pusher sliding block, and jack compatible with stroke slotting tool is offered on one group of pusher sliding block.
Further, the center of the punch-pin bottom end is provided with lug boss.
Further, the height of the single pusher sliding block is less than height of the stripper apart from cavity plate.
Further, the opposite end walls of one group of pusher sliding block protrude from dressing stick and act in advance.
The beneficial effects of the invention are as follows：Lug boss is arranged at punch-pin center in the present invention, by the side for taking out hole after punching again
Formula shaped axial hole, and stroke slotting tool and dressing stick linkage operation are set, have for reforming process and its molding process preferable
Guide effect, and be arranged pusher sliding block push open in advance take out hole material, guarantee the molding yield of axis hole, substantially increase product
Precision and working efficiency, industrialization are at low cost.
Detailed description of the invention
Present invention is further described in detail with reference to the accompanying drawings and detailed description.

Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, does not restrict the protection scope of the present invention.
A kind of transmission axis hole molding die as shown in Figure 1, including upper die holder 1, punch retainer 2, stripper 3, punch-pin
4, cavity plate 5 and lower die holder 6, punch retainer 2 are mounted on the bottom of upper die holder 1 by straight pin 7, installed on punch retainer 2
There is punch-pin 4, and punch-pin 4 is corresponding with the cavity plate 5 on lower die holder 6 across stripper 3, and one group of row is symmetrically arranged on upper die holder 1
Journey slotting tool 8, the opposite face of one group of stroke slotting tool 8 are provided with the first guiding incline 9, and lower die holder 6 is symmetrically arranged in the two sides of cavity plate 5
One group of dressing stick 10, one group of dressing stick 10 are provided with compatible with the first guiding incline 9 second in the end face back to cavity plate 5 and lead tiltedly
Face 11, and the upper surface sliding of one group of dressing stick 10 is provided with pusher sliding block 12, offers and stroke on one group of pusher sliding block 12
The compatible jack 13 of slotting tool 8.
In the present embodiment, the center of 4 bottom end of punch-pin is provided with lug boss 14, by the side for taking out hole after punching again
Formula shaped axial hole guarantees the formed precision of product.
In the present embodiment, the height of single pusher sliding block 12 is less than height of the stripper 3 apart from cavity plate 5, for avoiding
The movement of pusher sliding block 12 causes to interfere to molding or die sinking, guarantees the stability of mold entirety.
In the present embodiment, the opposite end walls of one group of pusher sliding block 12 protrude from dressing stick 10 and act in advance, so that whole
Before shape block 10 acts, pusher sliding block 12 pushes the material for taking out hole open, convenient for shaping operation later.
The beneficial effects of the invention are as follows：Present invention shaped axial hole by way of taking out hole again after punching, and row is set
Journey slotting tool and dressing stick linkage operation, and pusher sliding block is set and pushes the material for taking out hole open in advance, guarantee the molding yield of axis hole, greatly
Product Precision and working efficiency are improved greatly, industrialization is at low cost.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
