Description
Technical field
The utility model relates to a kind of cold punching dies, more particularly to a kind of enclosed type bending side core-pulling stamping die.
Background technique
Traditional enclosed type bending must increase by a pre- beading of step bending before bending and answer to reduce bending part bending
Power, and because be enclosed type bending, in bending among enter block and acted because cannot achieve de- material, so can not among when bending
Be packed into block, and there is also some problems for product when realizing enclosed type bending: often opening has ruler to enclosed type bending product
Very little tolerance is supported because that can not be packed among product into block, and size fluctuation is big after bending, there is larger rebound, product
Poor dimensional stability, yields are up to about 80%.
Summary of the invention
The purpose of this utility model is to provide the high enclosed type bending side pumpings of a kind of bending good stability of the dimension, yields
Core stamping die.
To achieve the above object, the technical solution of the utility model is:
The utility model is a kind of enclosed type bending side core-pulling stamping die, including cope plate, stripper plate, lower template, under
Baffle plate, sliding block, reset spring, Loose core block, de- material block, driving punching, bending block, buoyant block, buoyant mandril, buoyance lift spring；Institute
The cope plate stated, stripper plate, lower template, lower mould bottom plate are successively superimposed together, and sliding block slips in the slide block slot of cope plate, multiple
The both ends of position spring are acted against respectively on the inner wall of sliding block and cope plate slide block slot, and the outer end of Loose core block is fixed on the interior of sliding block
End, the bending chamber being fixedly mounted on stripper plate is stretched in the inner end of Loose core block；The bending block is fixed in lower template, buoyant
Block activity is nested in bending block, and the lower end of buoyant block and the upper end of buoyant mandril abut against, the lower end of buoyant mandril and buoyance lift bullet
Spring abuts against, and buoyance lift spring is nested in lower mould bottom plate；The lower end of the driving punching is fixed in lower template, drives the upper end of punching
It penetrates stripper plate and is abutted against with the outer end of sliding block.
After adopting the above scheme, it is replaced due to the utility model in mould inside design enclosed type bending side core-pulling mechanism former
Come without core pulling bending structure, the utility model passes through the tube bundle extracting machine that is made of sliding block, reset spring, Loose core block, driving punching etc.
Structure makes inside realize infolding and bend into block support, greatly improves the stability of bending size, and the control of opening dimensional tolerance exists
Positive and negative 0.08mm, so that the yields of product reaches 98% or more.
The utility model is further described in the following with reference to the drawings and specific embodiments.

Specific embodiment
As shown in Figure 1-Figure 3, the utility model is a kind of enclosed type bending side core-pulling stamping die, including cope plate 1, de-
Flitch 2, lower template 3, lower mould bottom plate 4, sliding block 5, reset spring 6, Loose core block 7, de- material block 8, driving punching 9, bending block 10, buoyant
Block 20, buoyant mandril 30, buoyance lift spring 40.
Include cope plate 1, stripper plate 2, lower template 3, the lower mould bottom plate 4 is successively superimposed together, and sliding block 5 is slipped upper
In the slide block slot of template 1, the both ends of reset spring 6 are acted against respectively on the inner wall of sliding block 5 and 1 slide block slot of cope plate, Loose core block 7
Outer end be fixed on the inner end of sliding block 5, the bending chamber 21 being fixedly mounted on stripper plate 2 is stretched in the inner end of Loose core block 7；Described
Bending block 10 is fixed in lower template 3, and 20 activity of buoyant block is nested in bending block 10, the lower end of buoyant block 20 and buoyant mandril
30 upper end abuts against, and lower end and the buoyance lift spring 40 of buoyant mandril 30 abut against, and buoyance lift spring 40 is nested in lower mould bottom plate 4；Institute
The lower end for the driving punching 9 stated is fixed in lower template 3, and the upper end of driving punching 9 penetrates stripper plate 2 and abuts against with the outer end of sliding block 5,
Driving sliding block 5 moves inward.
Working principle of the utility model is:
1, as shown in figure 3, die opening state, 1 downlink of cope plate, preparation start to act.
2, as shown in figure 4, starting inner core pulling feeding moment, stripper plate 2 and sliding block 5 are goed deep into 1 downlink of cope plate, driving punching 9
Contact will start to drive inner core pulling sliding action.
3, as shown in figure 5, in driving 7 feeding process of Loose core block, in 1 downlink of cope plate, driving punching 9 pushes sliding block 5 to move
Loose core block 7 is pushed ahead, starts to be contacted with material strip, is slowly inwardly promoted.
4, as shown in fig. 6, driving Loose core block 7 slides into place, in 1 downlink of cope plate, driving Loose core block 7 is slid into place, is made
Enclosed type bending side core-pulling mechanism enters block, can make the internal function of realizing infolding and bend into block support with supporting material band.
