Figure 11 is and the similar sketch of preceding figure that it illustrates conveyer mechanism and just workpiece is inserted tractor-drawn rake.
In following explanation, used equal reference numbers number is identical or equal parts in the accompanying drawing.
As shown in Figure 1, traditional forcing press is made up of two molds (9) and (10), mold (9) is provided with recess, to hold the workpiece (13) that is shaped and cuts out by synthetic thermoplastic material's sheet (8), this mold (10) carries the mechanism of model (11) and at least a portion cutting hot forming part, in each accompanying drawing, this mechanism all is omitted.
Two molds (9) among Fig. 1 and (10) show the position when they are slightly opened, and are inserted between bottom mold (9) and the sheet (8) to allow extracting plate (12) out.
Plate (12) is movably, and its head (14) is connected to an arm (not shown), and it is controlled by means of known mechanisms, opens insertion and removal between the molds (9) and (10) two.
Plate (12) is provided with recess (17), and this mouthful has with it relatively and the corresponding profile of the corresponding part of the workpiece that is drawn out of.
Though there is not display board (12) to be provided with slotted eye (18) among Fig. 1, the cooling fluid circulation time uses in the plate to supply with, but especially in Fig. 5 as can be known, slotted eye (19) has hole (20), they are connected to a vacuum and compressed air unit (the 5th figure does not illustrate), can adjust suction and pressure.
As shown in Figure 1, when plate (12) is inserted between two molds (9) and (10),, also can move, so can utilize a device (not illustrating among the figure) to carry its mold (9) facing to the device axis because it meets at right angles when mobile facing to the device axis.Simultaneously, a negative pressure results from the workpiece (beaker) (13), and nationality hole (20) and slotted eye (19) keep workpiece to prop up seating surface (17), and mold (9) continue its downward path, to reach position shown in Figure 2.
Then, utilize piston (22) to cause end (21) and beaker (13) separately, move according to the direction shown in Fig. 3 arrow (23), leave the unit that is shaped and cuts thereby carry beaker (13) so that allow plate (12).
With reference to Fig. 1, when not wishing that becoming coaxial relation to move with forcing press extracts plate (12) out, thereby when stopping to prop up its mold (9), beaker (13) can separate from the wall of recess, wherein, it is to have utilized the Tibetan to put piston (22) to act on its base portion (21), thereby beaker (13) can adhere to position (17), it is attached on (17) by negative pressure, and this negative pressure is produced in beaker by above-mentioned slotted eye (19) and (20).
Yet in case plate (12) leaves the unit that is shaped and cuts with beaker (13), plate (8) is when proceeding next step then, and as shown in Figure 3, the mold of forcing press (9) moves by the direction of arrow (24), to push another group beaker.
Simultaneously, because being connected between interruption board (12) and vacuum unit, or change-over panel (12) is to the compressed air unit, on the continuous poriferous band (43) that the result drops on beaker (13) to be provided with revolving drum (44), and owing to the suction of the suction diffuser (46) that communicates with vacuum source (not drawing among the figure) by pipe (47), beaker (13) stops within it with upright position.This movable conveyer device is by whole the illustrating of the reference number among Fig. 3 (42), and this device is carried to beaker another operation post, for example red ink paste used for seals or treating selvedge etc. in a sequential manner.
With reference to Fig. 4, as can be known, plate (12) is identical with the plate shown in the preceding figure, and can implement identical operations, uniquely different is, its head (14) also can be with the turning cylinder of pin (15) as it, and the axis of pin (15) is parallel to plate (12) body.In fact, in case beaker (13) just can make beaker be fed in the slotted eye (being formed by tiny bar (25)) of horizontal tractor-drawn rake (26) from being shaped and the unit of cutting when removing.When plate (12) was mobile, the negative pressure in the beaker made it be subjected to thrust in air, thereby prevented that its slave plate (12) separately.
When in case beaker (13) has been fed in the slotted eye of tractor-drawn rake (26), be enough to be breaking at being connected between plate (12) and vacuum unit in this case, or it is transformed into the compressed air unit, and make beaker slave plate (12) separately, and rest in the tractor-drawn rake (26).
Then, make plate (12) take a certain position, it can extract another group beaker out from there.According to the embodiment shown in the figure (6), as can be known, seating surface (27) is by formed corresponding to the slotted eye at beaker (13) edge, therefore, has greatly increased surface area, promotes stability or the cooling that prolongs the beaker thick.
With reference to embodiment shown in Figure 7, as can be known, seating surface (29) comprises the protrusion in the plate (12), and it is connected to groove (27) and has a profile, make it can adhere to the workpiece that is extracted at least in part, it comprises covering or lid (31) in this case.Though Fig. 7 does not show, can know to have the protrusion (29) of the frutum shape of cone, and its flat part is contacted with lid (31), promptly contacts with its thick.
With reference to Fig. 8 and Fig. 9, as can be known, mold (9) is positioned at the top of sheet (8) and can be used as makes cup (30), and aspect in addition, mold (10) is positioned at the below of sheet (8).
In Fig. 8,9, plate (12) has seating surface (16), is included in and is taken out in the relative plane of workpiece, in addition, though not expression among the figure, this plate (12) is provided with slotted eye (19) and hole (20), with the same among the embodiment that narrates previously.
In addition, will be appreciated that, this plate (12) can move by means of the axis to device, or the direction that meets at right angles with it moves, and be inserted between mold (9) and the sheet (8), and, by means of plate itself around inserting its head (14) and to the rotation of the rectangular alignment pin of plate (12) (48), plate (12) can be removed.
The plate of present embodiment (12), other of end (21) and two molds (9) and (10) moves described identical with Fig. 1 to Fig. 3, similar with movable conveyer removal mode of operation, this conveyer also can be replaced by movable conveyer (32), about (32), will in figure (10), (11), be illustrated.
In the end in two accompanying drawings, plate (12) has seating surface (16), and it is included in the board plane relative with workpiece, and can implement identical moving and operation described as Fig. 1-3, plate (12).Mold (9) and (10) are as on the same position as shown in Fig. 3 and Fig. 4, but and processing and manufacturing covering or lid (31), they can be by removal on movable conveyer (32).Covering or lid (31) utilize the excess pressure removal of recess, then, utilize the interior slotted eye (not illustrating among the figure) of pipe (34) and (35) and plate (36) to be connected to a vacuum and compressed air unit (not illustrating among the figure), move in the storage thereby utilize adjustable suction and pressure will cover (31).(31) then owing to storage (33) sucking-off air is fixed, (33) can rotate by means of leverage (37), this mechanism can rotate around axle (38), and the other end utilization pin (39) at it pivots facing to plate (36), plate (36) fuses with connecting rod (35), and bar (35) can move to the standing part (not illustrating among the figure) of the supporting frame of movable conveyer (32) between the sleeve (40) of axle (41).
Rotation by means of lever (37), direction shown in arrow (45), storage (33) moves towards tractor-drawn rake (26), in case lid (31) has entered by in the formed slotted eye of bar (25) time, it since the excess pressure that is produced in the storage (33) drop in the tractor-drawn rake in a sequential manner.
Then, storage (33) utilizes leverage (37), (38), (39), (40) and (41) to return to the position shown in the figure (10), so that pressures cycle is accepted lid (31) next time.
Any relevant personnel that are familiar with this technology can know, about the described extraction plate of various embodiment, can be in conjunction with the workpiece of Any shape, though they can not pile up, also can in conjunction with movable conveyer and tractor-drawn rake inequality shown in the drawings.
