Description
Technical field
The present invention relates generally to have the stamping system of material feed mechanism, specifically, relate to a kind of time method and device that is used in the material feed mechanism, determining and setting the material releasing mechanism.
Background technology
In general, the part by the automatic press machinework utilizes a mould that advances.This mould that advances uses a plurality of stations, and each station comprises the drift of at least one punching or shaping and the mould or the mould of coupling usually.Utilize an automatic pay-off,, advance to another station, present to stepping and pass through mould from a station with being used for the continuous band of processing parts.Corresponding to the distance between each mould station, mobile off and on band one distance of a material feed mechanism, simultaneously, mould is opened.Then, this mechanism stops at material on each station, and at this moment, mould is closed.The visible US Patent 5,755,370 of the example of the material feed mechanism of prior art; 5,868,296; 5,915,293; With 5,808,465.
Aligning apparatus is thought that by the mould that is used at large advancing each operation thereafter is positioned at band on the mould, and this location is more accurate than the possible location of material feed mechanism.The location guide pin at the tip that general and the most understandable aligning apparatus is a taper or gradient or a plurality of such guide pin.Location guide pin is installed on motion (the being generally top) die shoe.Normally, a diameter is than the big slightly hole of diameter of location guide pin, and in the process that mould is closed for the first time, punching is on the continuous band on first station.Then, corresponding to the distance between the station thereafter, the material feed mechanism moves a predetermined distance with material automatically.Thereafter mould is firm closes, and location guide pin (its length is greater than the punch length of work) enters the hole that is formed by drift, and locator material exactly.
Location guide pin can be used for any amount of thereafter mould station.In order to allow location guide pin or other aligning apparatus locator material effectively and accurately, the material feed mechanism must unclamp the clamping on band.The timing of the release function of material feed mechanism is crucial, because of too early release can make the material outflow location, exceeds the scope that location guide pin comes into force.Perhaps, if the material feed mechanism discharges band after discharging late or not, then when location guide pin enters the hole, will in band, form tension force.The distortion that this can cause the hole forms the material of improper location.The material of this improper location will cause producing the part of deformity, and can damage location guide pin and mould.
The whole bag of tricks that discharges band from the material clamping mechanism is well-known in the prior art.These methods are utilized cam usually, cylinder, or various other device.Have the technology that is used between material feed mechanism and punching machine, setting and keeping the precise material releasing mechanism time at present.For example, referring to US Patent 5,720,421.In addition, this technology is to providing unlimited variation drop away time, and the device easily that is used to adjust this time.Yet when the aligning apparatus contact material, and the material clamping mechanism does not exist to be used for determining that accurate press slides or the technology of the position of press mechanism when take place discharging.
When the material feed mechanism should discharge its clamping on band, the difficult accurate point of determining in the punching stroke because of two pri problems.The first, aligning apparatus is usually located at the position that it is difficult to or can not with the naked eye detects.The second, the characteristic of the flywheel that is driven by the mechanical stamping machine makes it be difficult to accurately locate to the amount of going forward one by one for a short time Punching slider.For a short time the motion process of the Punching slider of the amount of going forward one by one is referred to as " slow-action " or " moving frequently ", and at short notice, the punching machine power-transfer clutch is finished the engagement of repetition.This causes a very fitfull motion, and makes it be difficult to accurately locate Punching slider, with the accurate position of check aligning apparatus with respect to band.The difficult characteristic of the method for prior art can be proved absolutely by example.
There is the time method be used for determining and setting correct material releasing mechanism in prior art, but the operator that these methods require punching machine usually is positioned at the position that in the mould one allows die-cut initial knock hole with material.Then, the operator must implement moving with closing molding of punching machine slide block, punches out knock hole on material.The material mono-input of advancing then, thus, locator material correctly closes the material of closing to allow the aligning apparatus contact at thereafter mould.The operator then " slow-action " and " stopping " punching machine arrive that the material alignment device begins contact material certain a bit.The material alignment device begin contact material certain a bit come by the following method to determine: with the naked eye, perhaps, catch material, the mobile or mobile material of trying, and sense-data moves and is aligned that device stops and the feel of being obstructed with hand.Determine that the good material aligning apparatus begins the position of the punching machine of contact material, the operator adjusts the material feed mechanism then, with before this position at punching stroke on this location point or slightly, discharges the clamping to material.Then, repeat this process and adjust, up to the time of material releasing mechanism be proved suitable till.

The specific embodiment
As Figure 1-3, the present invention relates to a stamping system 10, it comprises a punching mechanism 12, one material feed mechanisms 14 and a material dispenser 16.Material feed mechanism 14 is used for an elongated band 18 is fed to punching mechanism 12 from material dispenser 16 by material feed mechanism 14.This punching mechanism 12 generally includes a tool mechanism 17 with last die shoe 20 and lower die shoe 22.Last die shoe 20 is installed on the Punching slider 24 on the punching mechanism 12.The last die shoe 20 of tool mechanism 17 has the aligning apparatus 28 that a punch device 26 and is installed in its downside.Punch device 26 is constructed to be permeable to dash to be worn or die-cut material 18 down.In this preferred embodiment, aligning apparatus 28 is location guide pins 30.As mentioned above, die shoe 20 is installed on the Punching slider 24 on this, and it can move up and down with respect to lower die shoe 22.The lower die shoe 22 of tool mechanism 17 is installed on the backing plate 32 that is installed in rigidly on the fixed punch press body 34.
One material releasing mechanism 42 comprises a material clamping device 44, and it is worked together with feed drive roller 40, to clamp material 18.Usually, this material clamping device 44 is assistive drive rollers.Material clamping device 44 is installed on the pivot framework 46, and it is pivotably mounted on the material feed mechanism framework 48.Material releasing mechanism 42 also comprises an actuator 50 (being generally compressed-air controlled), and it can be applied to downward pressure on the pivot framework 46, thus, makes material clamping device 44 clamping material 18 between material clamping device 44 and feed drive roller 40.
From Fig. 3 as seen, also can infer material feed mechanism 14 and comprise that one drives the motor 52 of a release screw piece 54, screw piece and nut 56 couplings realize the motion of pivot framework 46 with the power of opposing actuator 50.The structure of this just release screw piece 54 and nut 56 just makes the material clamping device move from feed drive roller 40, thus, is released in the clamp pressure on the band 18.
In order to determine the time of desired material releasing mechanism, stamping system 10 also comprises a location device 58.In a preferred embodiment, this registration device 58 comprises a controller 60, and the position of its monitoring punching mechanism 12, and be that material releasing mechanism 42 is determined required times is with contacting of release and material 18.In addition, this controller 60 time that can realize desired material releasing mechanism 42 and punching mechanism 12 positions is related.Also can infer registration device 58 and comprise one first positioner 62, its be used for monitoring, collect and transmit relevant punching mechanism 12 with and the information of parts to controller 60.Similarly, one second positioner 64 can be used to monitor, collect and transmit relevant material feed mechanism 14 with and the information of parts to controller 60.
In a preferred embodiment, registration device 58 utilizes first positioner 62 to monitor the bent axle 36 of punching mechanism 12.Next, this first positioner 62 arrives controller 60 with the angular position information transfer of bent axle 36.Second positioner 64 is installed on the feed drive roller motor 38, and be used for monitoring and the angular position of transmitting feed drive roller motor 38 to controller 60.At last, according to the 38 desired motions of feed drive roller motor, and the actual angular position of the motor that records, controller 60 calculates position error information.According to the position error information that calculates above, controller 60 also can calculate the torque instruction to feed drive roller motor 38.This torque instruction is sent to motor 38.And according to definition, desired torque instruction can be used as and/or be related to the torque of the motor 38 of measurement.Although registration device 58 has been described to be used for monitoring above-mentioned specific equipment, but can infer and do hereinafter discussed in detailly be, this registration device 58 can be used to any one actual characteristic according to the parts of stamping system 10 and equipment (comprising feed mechanism and punching machine itself), monitoring and the time of definite desired material releasing mechanism 14 and the position of punching mechanism 12.
As shown in Figure 5, the present invention comprises that also one determines the method for the correct time of material releasing mechanism 14.In order to determine this time, punching mechanism 12 circulates by the working portion of the aligning apparatus 28 of tool mechanism 17.The position of punching mechanism 12 is monitored.Above-mentioned registration device 58 can be used to determine that material releasing mechanism 42 discharges the required time that contacts with material 18.Usually, discharge required time just in aligning apparatus 28 (or in the present embodiment, location guide pin 30) with before material 18 contacts.Next, the location association of the time of the desired material releasing mechanism 14 of Que Dinging and punching mechanism 12.On the whole, this will allow material releasing mechanism 42 unwound material 18, at material clamping device 44 before contact material 18 and material feed mechanism 14 continue to present once more, allow location guide pin 30 to contact with material 18 and will align with it.After required time is determined, can be adjusted to the time of definite desired material releasing mechanism 42 time of real material releasing mechanism 42.
In a preferred embodiment, location band 18 makes its front edge by comprising the first mould station of punch device 26.Then, punching mechanism 12 circulates by a complete punching stroke, punch device 26 is dashed wear or a die-cut hole 66 in band 18.Then, material 18 is by the material feed mechanism 14 predetermined distance (less than the input of mould) of advancing.This is locator material 18, so that location guide pin 30 roughly is positioned at the top in previous die-cut hole 66, but deviation slightly.This situation is shown among Fig. 4, but deviation is greatly exaggerated.In fact, this deviation is very little, has only 0.003 inch to 0.008 inch usually.
Next step is the working portion that punching mechanism 12 cycles through aligning apparatus 28, and passes through a punching stroke completely usually, and controller 60 is synchronously monitored the position of feed drive roller motor 38.When last die shoe 20 was closed, location guide pin 30 entered into die-cut in advance hole 66, and material 18 is forced to and enters final aligned position.This causes positive clamping the motion of the clamping device 44 and the feed drive roller motor 38 of material 18.When press cycle is finished, controller 60 is analyzed the information of collecting, and with the motion of material releasing mechanism 42 (comprising material clamping device 44) and feed drive roller motor 38, location association with punching mechanism 12, thus, determine the position of punching mechanism 12, wherein, location guide pin 30 enters into band 18.The example of this associated data is shown among Fig. 6.At last, to material feed mechanism 14, particularly material releasing mechanism 42 is programmed, and thinks press cycle thereafter, in the position of the punching mechanism 12 that calculates, releasable material 18.In this preferred embodiment, controller 60 is automatically set point of release accurately, and with the usefulness of information storage for future.
What also can infer is that location guide pin 30 contacts the exciting force that causes with material 18 can be measured.As mentioned above, this measurement can be used to determine 42 times of desired material releasing mechanism.The guide end 68 of location guide pin 30 with hole 66 full engagements after, the torque that acts on the feed drive roller 40 also can be measured.Similarly, also can measure the power that acts on the material clamping device 44.Then, these measurements can be used to determine the time of desired material releasing mechanism 42.The motion of the material 18 on material dispenser 16 also can be measured, and be used for determining the time of desired material releasing mechanism 42.Act on the torque on the feed drive roller 40, act on the power on the material clamping device 44, and the positional error of feed drive roller motor 38, all can be used to determine the time of desired material releasing mechanism 43.What also can infer is, any one during controller 60 can be used to monitor, transmit together with suitable positioner (62,64) and measure according to these calculated the time of desired releasing mechanism 42.
Generally speaking, the present invention is a stamping system 10 and the time method that is used for determining and adjusting desired material releasing mechanism 42.When using controller 60, the present invention is an automatic system, and it eliminates the estimation work of before having been adopted by the user for the time of setting material releasing mechanism 42 in the prior art.This increases productivity significantly conversely and reduces operator error and the possible safety problem of operator.
The present invention determines the position of accurate punching mechanism 12 (normally Punching slider 24) when aligning apparatus 28 is about to contact material 18 and material release will take place.On the accurate location point of in punching stroke this, material feed mechanism 14 will discharge its clamping on band 18 just.As above described in detail, this is accurately put is to be determined according to some parts of stamping system 10 and motion linearity or angle of assembly by controller 60.Yet what also can infer is, can use one or more sensors be positioned at punch device 26 or aligning apparatus 28 near.The contact of detectable aligning apparatus 28 of such sensor and/or punch device 26 or accurate location, and this information can be used to determine the time of material releasing mechanism 42.For example, if finish a circuit, the then detectable contact that goes out punch device 26 or aligning apparatus 28 thus, is determined the drop away time of material 18.In addition, sensor can be used to directly measure the motion of material 18, so that determine the time that material 18 discharges.Perhaps, when aligning apparatus 28 was just entering hole 66, material 18 mechanically trembleed (or front and back move).The contact of the front and back of the sidewall of the guide end 68 of utilization location guide pin 30, controller 60 can be determined the time of material releasing mechanism 42.
In addition, although above-mentioned preferred embodiment relates to is driven roller in feed drive roller 38 and/or the material feed mechanism 14, and material clamping device 44, but will be appreciated that, material feed mechanism 14 can adopt the slip clamper to advance band 18, and/or slide or fixing clamper, they are as the part of material feed mechanism 14 and/or material clamping device 44, and/or as the part of material releasing mechanism 42.
