<7>Waste disposal means in the perforation processing unit (plant) of second technical solution

If carrying out perforation processing according to the method for perforation processing of above-mentioned cornue W, waste material S is generated.For the technical program Waste material S processing means and process combination Figure 12 (a), Figure 12 (b) be illustrated to 14.

For handle waste material S, the transferring element 41 of interior side mold device 4, downside expand/reduce block 42 and upside expansion/ Block 43 is reduced equipped with the air duct 45 to 47 for spraying air.

Set on the air duct 45 of transferring element 41, one end is connected to air-source by air hose 48 (please referring to Fig. 8).On The air duct 45 for stating transferring element 41 is connected to downside expansion/diminution block 42 air duct 46, and is connected to waste material receiving Portion 28.If generating from air-source from the instruction of control device output blowing by air duct 45 and 46, by compressed air It is expelled to the air-flow F1 (please referring to Figure 13 (b)) of waste material receiving portion 28.By said flow F1, generated in process of perforating Waste material S is in the waste material receiving portion 28 of interior side mold device 4, by the opening portion 44 of inside die device 4 to the opening of cornue Portion's discharge.

Expand/reduce the air duct 47 of block set on upside, one end of air duct with it is (interior in cornue W to be processed The outside of side mold device) outside air connection.The other end is connected to waste material receiving portion 28.As shown, air duct 47 It is equipped with opening portion (please referring to Figure 13 (a), Figure 13 (b)) in the position of the bottom dead centre for the blade 25 for being higher than formed punch, i.e. air duct 47 are being connected to higher than waste material receiving portion 28 with the position of the bottom dead centre of the blade 25 of above-mentioned formed punch.

If compressed air is discharged in the air duct 46 for expanding/reducing block 42 from downside, generated in waste material receiving portion 28 Negative pressure generates the air-flow F2 that the outside air in cornue introduces waste material receiving portion (please referring to Figure 13 (a), Figure 13 (b), Figure 14 (a), Figure 14 (b)).This air-flow F2 is the flowing in the position of the bottom dead centre for the blade 25 for being higher than formed punch to waste material receiving portion 28, And as shown in Figure 14 (a), generate the function and effect that the waste material S for the blade for being attached to formed punch is isolated from the blade 25 of formed punch.This When, as shown in Figure 10 (a)~Figure 10 (c) to Figure 14 (a), Figure 14 (b), if the blade 25 of formed punch is made to be equipped with the air for discharge The structure being slightly tilted that broadens toward upside of direction, then can promote the separating effect of the waste material S using air-flow F2, further mention The discharge effect of high waste material S.

The treatment process of waste material S is illustrated.Waste disposal process is made of following process 1 to process 7.To each work Sequence is successively illustrated.

<Process 1>Please refer to Figure 12 (a)

Cornue to be processed is in the state that positioning is completed relative to outside mould device 3 below.State is perforation processing Before, the waste material S that the cornue of processing is completed passes through the gas as shown in Figure 13 (a), Figure 13 (b) and Figure 14 (a), Figure 14 (b) Stream F1 and F2 is expelled to the state of the opening portion (right side of this attached drawing) of cornue.Air is not blowed in process 1.

<Process 2>Please refer to Figure 12 (b)

It is that cornue is positioned at Working position and the state before perforation processing.Outside mould device 2 declines, and inside Die device 4 is adjacent to the inner face of cornue by expansion/diminution movement, is before the decline of blade 25 of formed punch is contacted with cornue.? Also air is not blowed in process.

<Process 3>Please refer to Figure 13 (a), Figure 13 (b)

Indicate that the decline of blade 25 of formed punch carries out perforation processing, the blade 25 of formed punch reaches the state of bottom dead center-nearby.This When, waste material S moment is in the state for being attached to the blade of formed punch.Start to dry near this state (time point).Compared with figure 13 (a), indicate that the blade 25 of formed punch blows air from air duct in bottom dead centre and forms air-flow F1 in Figure 13 (b), thus useless Expect that receiving portion 28 forms negative pressure, the outside air in cornue generates the state of air-flow F2 by air duct 47.

As described above, because being to perforate to process to begin to decline until reaching bottom dead center-nearby not blow from the blade end of formed punch Air is sent, waste material S will not waft in the waste material receiving portion 28 of interior side mold device during the decline of the blade of formed punch.To The problem of waste material S flies up from waste material receiving portion 28 and is adhered on the inside of the lifting part or tubing of outside mould device can be eliminated.

<Process 4>Please refer to Figure 14 (a)

Indicate the state that the blade 25 of perforation process finishing and formed punch rises.Air-flow F1 for waste material S to be discharged still is held It is continuous.Because the blade 25 of formed punch rises, the opening portion for expanding/reducing the air duct 33 of block 43 set on upside becomes larger.To root Negative pressure is generated in waste material receiving portion 28 according to the air-flow F1 from air duct 46, and the outside air in cornue introduces waste material receiving The air-flow F2 in portion 28 becomes much larger compared with the state of process 3.It drop to the waste material S of waste material receiving portion by processing of perforating, passes through Air-flow F1 is discharged to the opening portion of cornue.At this point, by the air-flow F2 from outside air of air duct 47 play waste material S by In air-flow F1 wafts the case where.In addition, air-flow F2 plays the waste material S by the blade of formed punch is attached to because of perforation processing from formed punch The effect of blade separation.At this point, as described above, broadening if the blade of formed punch is equipped with using the direction of the air to discharge toward upside Slight inclination formed punch blade 25, then can further promote the centrifugation of the waste material S by air-flow F2.

<Process 5>Please refer to Figure 14 (b)

It is the end rising of blade 25 of perforation process finishing and formed punch, cornue carries out the state before positioning movement.For The air-flow F1 that waste material S is discharged still continues.Therefore, the air-flow F2 from air duct 47 is also generated.In this process, because of formed punch Blade 25 rise in higher than cornue position, thus perforation processing cornue hole in flow direction is also formed by outside air The air-flow F3 of waste material receiving portion 28.By said flow F1, F2 and F3, waste material S passes through interior side mold in waste material receiving portion 28 The opening portion 44 of device 4 is discharged to the opening portion of cornue without safety.Air supply from air-source is to hand over next time from cornue The stopping of process 2 that work starts mobile process finishing running fix next time in place before is advisable.

Process 1 is repeated to process 5 by certain number according to the perforation form processing of cornue.

When the perforation process finishing of cornue, waste material S is in the state for being moved to the opening portion direction accumulation of cornue.It is perforating The state of processing unit (plant) returns in the state of original position, and operator separates cornue and discards the waste material S in cornue to bucket etc..

Waste disposal means and treatment process is described above.In the waste disposal means and treatment process of the technical program In, because only utilize inside die device in waste material receiving portion progress waste disposal, thus even if because cornue thickness or height The volume of size waste material receiving portion becomes smaller, and suspends perforation processing unit (plant) completely without for processing waste material.So as to substantially mention The production efficiency of the perforation processing of high tubing.
