Abstract
A press mounted cam has a slide guided on an adapter by structural features including as one or more T blocks fixed to the slide and received in a respective channel formed in the adapter. In an aerial cam embodiment, a vertical clearance space is provided between the T block and adapter channel such that positive driving engagement between cam surfaces on the slide and the adapter is momentarily delayed after the initial engagement of the slide and driver surfaces to let the momentum of the slide be absorbed prior to the beginning of positive driving by the press motion, reducing shock and noise. The slide is laterally located with respect to the driver by an upwardly projecting locator-guide key on the driver received in a central channel in the slide. A positive return is provided by engagement of a driver key having T features received in a T-shaped slide channel and captured therein when the slide is driven laterally. This engagement creates a positive return of the slide when the press upper platen is raised.

Background technology
The present invention relates to the pattern of assembling press, it is configured to form pressure generating part on workpiece by mould, and this mould has the top on the top board that is arranged on press and is arranged on bed die part on the lower platen of press.This pattern is used for forming punching or screwed hole so that it must form along the moving of operating angle direction transverse to the press moving direction by cutter at the part position place.The pattern of described assembling press is used to produce this cross tool motion.
These patterns comprise " slide ", and the carrying cutter is connected in " main body " on or " connector " in mould or the press pressing plate, and slide slidably assembles thereon, be assemblied in mould or the press pressing plate " driver " on another that separates.This driver engages with slide, and when press was operated, it was by the engages drive slide of cam surface.
In " air " pattern shown in Figure 1, slide 12 hangs on main body or the connector 10, and it can directly be assemblied in top board 2 or more typically be assemblied on the top 6 of shaping dies.Driver 14 can directly be assemblied in lower platen 4 equally or typically be assemblied on the bottom 8 of shaping dies and have the constant tilt pattern face 16 that is parallel to operating angle, its typically the wear plate of the parallel surface by being connected in driver 14 and slide 12 determine.
When top board 2 declines, consequent pattern action causes slide 12 to advance along the resistance of the one or more relatively springs 15 of operating angle, and it carries from the cutter T of slide 12 projections and is driven in this direction.The horizontal component of this motion needs work slide 12 also laterally to move on connector 10.For this purpose, provide engaged horizontal support surface 18,19 at the top of slide 12 and the bottom of connector 10 respectively.In another structure, can there be a horizontal surface on the inclined plane in the embodiment shown in fig. 12 on the driver on connector.
In the pattern of " assembling mould " (shown in Figure 2), slide 12 and connector 10 all are assemblied in the lower platen 4 that does not move (or mould part 8), and driver 14 is assemblied in the mobile top board 2 (or mould part 6), and engages with slide 12 along with press top board 2 descends.
Therefore the pattern of this assembling mould can not cause occurring in vertically the moving along with top board 2 of heavier slide 12 relatively in the air pattern.This vertical the moving of slide can cause following problem, but because the air pattern has been made clearance space workpiece is moved into or shift out mould and press allowing, so it often is used.
In other pattern trim designs, for the relative accurate aligned cutting tool T of workpiece W, slide 12 must be by accurate located lateral when driving, and in order to realize this location, actual practice is to form cam surface 16A under the V-type so far, with when slide 12 engages with driver 14, on driver, provide the located lateral and the cam surface of slide, shown in Fig. 3 and 4.
The pattern that this outerplanar 16B needs large-size sometimes is applied to pressure slide 12 on to distribute by press so that enough area to be provided.The accurate coupling on V-type surface is difficult, and the actual cost of making slide 12 and driver 14 that increased.
Especially in large-size, need large-sized machining center in the demand that is positioned at processing parts on connector 10 outside these elements and the slide 12, essence has increased manufacturing cost.
In the air pattern because the big quality of slide 12, auxiliary roller cam 28 in order to before the joint of cam surface by with the engaging of the working groove 30 of driver 14, initial and help slide block to be displaced sideways.This help helping horizontal break-in that slide 12 moves with reduce peak stress and follow generation noise vibration and the wearing and tearing of cam surface.Yet roller cam 28 essence have also increased the cost of this air pattern.
If the back-moving spring 38 in the casket 36 lost efficacy owing to excessive impact load or owing to some other reasonses for example cutter can't be return by the serious stuck cutter that causes, assist pattern to be provided to also guarantee that returning of slide 14 is mobile by the positive return that profiling bar 32 and 34 is formed.
This profiling bar 32,34 that resets is positioned at the outboard end of slide 12 and driver 14, therefore is difficult to make, especially in above-mentioned big pattern size.Simultaneously, bonding area therebetween is subjected to the restriction of the stroke of slide 10, and if cutter seriously shut down owing to need very big power with withdrawal slide 12, described bar 32,34 lost efficacy easily.
The purpose of this invention is to provide the air pattern that on matching block, applies littler vibrations and remove the needs of auxiliary roller cam.
Another purpose is to eliminate the difficulty of machinery maintenance and part location in the pattern of air pattern and assembling mould.
Another purpose provides a kind of firmer and durable positive return mechanical device that has that is used for air pattern and the pattern that assembles mould.
Summary of the invention
Above-mentioned or other purposes, it is more clear by reading the following description and claim, realize that by on connector, hanging slide and generating predetermined clearance space this clearance space laterally drives slide at press and must be occupied along operating angle before being driven by architectural feature.This temporary delay contact just generation by press is that drive with the joint pattern face slide and driver initial behind of short duration gap.This allowed before the slide that is caused by the press action is forced to drive along operating angle, at first being driven device to lower punch power and absorbing to reduce noise and to be applied to the lip-deep peak load that slide-driver matches of slide.
Described slide preferably hangs on the connector with the T piece that embeds relative T groove in the inner side of the connector head rest by the T piece on the surface of each side of groove by one or more slides that are fixed in.The needs of location, the outside retention plate on the slide sidepiece of previous use have been got rid of in the use of inboard location T piece.
This T piece and groove can comprise above-mentioned architectural feature, promptly between the stayed surface that is complementary of connector and slide, generate predetermined clearance space, thereby when slide at first contacted with driver, this clearance space must at first be occupied before press itself laterally drives slide.Driving between the connector that had temporary delay in this gap and slide coupling stayed surface engages, and is occupied up to this gap.Auxiliary thus roller cam has not just needed.
In the pattern of air pattern and assembling mould, one or more inboard location-feather keys are outstanding and move into gathering sill on the slide from driver, with in the slide cam surface and driver inclination cam surface is approaching is used for located lateral and guiding when engaging.Making located lateral-guide surface is easily.Location-the feather key of this inboard has also been removed the needs of accurately processing spigot surface in the slide end.
In addition, in the pattern of air pattern and assembling mould, can add a positive return device, it adopts a pair of separated T head that is fixed in driver location-feather key, and it moves in the T groove that matches in slide when separated opening in comfortable T groove by each engages slide, and it is hunted down when slide follows the Cheng Qian and advances.When positive return necessitates when being used for the power of positive return slide with the essence increase, it can effectively double to increase the length of composition surface of matching on driver and the slide.

When top board 84 when lower platen 86 descends, positioning key 80 enters groove 82, so that side location and guiding to be provided, referring to Fig. 8 B.
The preliminary contact in surface that the continuation of top board 84 descends and makes wear plate 76,78 is referring to Fig. 8 C.Though clearance space 58 has reduced, but still exist.
This preliminary contact of wear plate 76,78 allows the absorption and the changed course to lower punch power of 44 pairs of slides 44 of driver, thereby the transverse movement that causes slide 42 is activated, and the part of spring 68 shown in it passes through is compressed as can be seen.
It is pointed out that for easier in the drawings observation, the size of the degree of described motion and clearance space 58 is exaggerated demonstration.
In the next step shown in Fig. 8 D and 12, clearance space 58 is occupied now fully, and the forced draught of top board 84 causes slide 42 laterally to move forward along operating angle.Drive cutter 88 with this and contact, compress spring 68 fully at progressive position, as shown in Figure 9 with workpiece W.
Therefore, that has only slide 42 when preliminary joint of wear plate 76,78 is driven device 44 absorptions to lower punch power, and actual pressure-driven can be occupied up to clearance space 58 by temporary delay.This less vibrations of energy and noise, and the cam bawl of using always before not needing to use.
It is noted that if operating angle becomes more shallow, connector 40 will have a surface that is equipped with wear plate, another embodiment as shown in figure 10.
In this case, connector 40A also can be configured to adopt series of parallel plate 92, and it is assemblied on the base 93 and with base 93 to tilt at angle, and is similar with the form of driver 44A.T shape piece 96 passes the groove on the gripper shoe 94 and has the wing, and it leans against on the upper surface 95 of gripper shoe 96.97,99 of wear plates have the identical initial clearance space shown in the figure.
