Description

Upward blanking mechanism suitable for swing arm feeder of transfer die

Technical Field

The utility model belongs to the technical field of the stamping die technique and specifically relates to a be suitable for swing arm feeder of transmission mould blanking mechanism that makes progress.

Background

In order to improve the material interest rate, the traditional blanking mode is to utilize one-to-three blanking of a swing arm feeder or one-to-three blanking of a single punching die. But these two kinds of blanking mechanisms follow-up all need with the help of buttress material machine and mould interlock, and cause many-sided waste, for example: the method occupies more intermediate links such as one machine tool, manpower, process turnover, production time and the like.

Therefore, it is necessary to design an upward blanking mechanism of a swing arm feeder suitable for a transfer die to realize linkage of swing blanking and a subsequent die.

Disclosure of Invention

The utility model aims at overcoming the not enough of prior art, provide a be suitable for swing arm feeder of transmission mould blanking mechanism that makes progress to realize swing blanking and follow-up mould interlock.

In order to achieve the purpose, the utility model relates to a be suitable for swing arm feeder of transmission mould blanking mechanism that makes progress, include cope match-plate pattern, lower bolster, bullet clamp plate, take off flitch, drift, fixture block, spring, its characterized in that: the bottom of cope match-plate pattern is equipped with the upper die base, the bottom central authorities of upper die base are equipped with the recess, install in the recess and play a nail one, the top central authorities of lower bolster are equipped with the drift, install in the drift and play a nail two, the top outside of lower bolster is installed and is taken off the flitch, it adopts spring one to be connected between flitch and the lower bolster to take off, it installs the bullet clamp plate to take off the top of flitch, it is equipped with spring two with taking off between the flitch to play the clamp plate, be equipped with the cut mold insert on the interior disc of bullet clamp plate, the periphery of drift is equipped with the fixture block, the fixture block is installed.

The groove of the upper die holder corresponds to the position of the punch.

The four clamping blocks are respectively positioned on the left front side, the left rear side, the right front side and the right rear side of the punch.

And a 5 mm gap is formed between the elastic pressing plate and the stripper plate.

Compared with the prior art, the utility model, designed the swing arm feeder that is suitable for the transmission mould mechanism that makes progress, utilized reverse blanking to increase blanking stroke and let die-cut material upward movement, blocked the material with the fixture block and supply the manipulator to snatch, realized swing blanking and follow-up mould interlock. The utility model discloses make full use of punch press pure power does not rely on third party auxiliary power, and the suitability is strong, the structure is convenient succinct, shortened volume production cycle, energy saving by a wide margin.

Detailed Description

The invention will now be further described with reference to the accompanying drawings.

Referring to fig. 1-4, the utility model relates to an upward blanking mechanism of a swing arm feeder suitable for a transfer die, which comprises an upper template, a lower template, an elastic pressing plate and a stripper plate, the punching head, the fixture block, a spring, the bottom of cope match-plate pattern 1 is equipped with upper die base 7, the bottom central authorities of upper die base 7 are equipped with the recess, install in the recess and play first 71 of nail, the top central authorities of lower bolster 2 are equipped with drift 5, install in the drift 5 and play two 51 of nail, the top outside of lower bolster 2 is installed and is taken off flitch 4, it adopts first 9 of spring to be connected to take off between flitch 4 and the lower bolster 2, it installs to take off flitch 4 top and plays clamp plate 3, it is equipped with two 10 of spring between clamp plate 3 and the taking off flitch 4 to play, be equipped with cut-out mold insert 31 on the interior disc of clamp plate 3, the periphery of drift 5 is equipped with fixture block 6, fixture block 6 installs on mount 61, be equipped with three 63.

The utility model discloses in, the recess of upper die base 7 corresponds with the position of drift 5.

The four clamping blocks 6 are respectively positioned on the left front side, the left rear side, the right front side and the right rear side of the punch 5.

A gap of 5 mm is arranged between the elastic pressing plate 3 and the stripper plate 4.

When the utility model works, the material 8 is continuously fed between the 5 mm gap between the elastic pressing plate 3 and the stripper plate 4 in the die sinking state shown in figure 1; in the process of closing the die, the upper die base 7 presses down to act on the elastic pressing plate 3 and the stripper plate 4, the material 8 is blanked upwards under the blanking force of the punch 5 and the shearing insert 31, and the material 8 continuously floats upwards on the punch 5 along with the closing of the machine until the die is closed, as shown in fig. 2. At the moment, the material 8 floats on the fixture block 6, the second elastic nail 51 is arranged in the punch 5, a gap of 5 mm is formed between the material 8 and the punch 5 when the die is opened, the material 8 can be supported by the fixture block 6 after the die is continuously opened due to the effect of the gap, and a gap of 20 mm is formed between the clamping surface and the elastic pressing plate due to the fact that the waste is kept below the elastic pressing plate 3, so that a sufficient part taking space is reserved for the manipulator 11, as shown in fig. 3, and linkage of swinging blanking and a subsequent die is achieved.

The utility model discloses a be suitable for the ascending blanking mechanism of swing arm feeder of transmission mould utilizes reverse blanking to increase the blanking stroke and lets die-cut material upward movement, blocks the material with the fixture block and supplies the manipulator to snatch, realizes swing blanking and follow-up mould interlock. The utility model discloses make full use of punch press pure power does not rely on third party auxiliary power, and the suitability is strong, the structure is convenient succinct, shortened volume production cycle, energy saving by a wide margin.
