Describe the preferred embodiments of the present invention with reference to the accompanying drawings in detail, objects and advantages of the present invention will be understood more completely.In the accompanying drawing:
Fig. 1 is the schema that a helical spring method in the bag of packing into that couples together is made in explanation;
Fig. 2 is used to make a helical spring schematic representation of apparatus in the bag of packing into that couples together.
The present invention has the leeway of various improvement and structure replacement, but following is described in detail the preferred embodiment shown in the accompanying drawing.But, should be appreciated that this is not will limit the present invention in the particular forms disclosed, on the contrary, the present invention should cover in claims to be explained, and falls into all modified versions, alternative and equivalent in design of the present invention and the scope.
The present invention relates to a kind of whisker in the bag of packing into separately that couples together that is used to make, this whisker generally is used in the mat.The structure of spring is that the public is known, and is the same with structure in the Marshall patent.In this structure, each spring all is encapsulated in the fabric container or pocket of itself.Pocket generally is what to form between two an of fabric, that is, a fabric oneself to gathering into folds, then, after the space of packing into through the spring of overdraft between these two fabrics, longitudinally and laterally stitched together.
Please see Figure 1 now, represented the schema of the interior helical spring method of bag of packing into that one of explanation manufacturing couples together among the figure.Usually, this manufacturing processed is from providing a coil silk (10) and a roll of material (12).This roll of material infeeds folding work station (14) with a webbing, and fabric is own to gathering into folds on this workstation, and formation can be held the space through the spring of overdraft.
From the steel wire process heating (16) that steel wire coil is sent here, purpose is to eliminate the stress that produces in the technological process of making steel wire.The steel wire that will be in then under the high temperature is pushed instrument (18) to, makes steel wire bend to volution.Because heated, so that steel wire becomes is submissiveer, and the stress during winding shaping has also reduced.After the shaping, cut off (20) steel wire, whisker and a long steel wire of releasing from above-mentioned steel wire coil are separated.Then, at compression step (24) before, cooling (22) spring on the carousel of a rotation, above-mentioned compression step is compressed to spring and highly is about 0.5 inch.Should be appreciated that except the carousel of rotation, other machinery also can be used to cool off spring.For example, can use a transfer roller.After overdraft, above-mentioned wire spring is inserted in the space that (26) form in the fabric that folds.Then, make the spring and the fabric that combine lead to a worktable (28), on this worktable, selectively two fabrics are connected into pocket with ultrasonic welding.This connection procedure both carried out on the fabric between each spring, was also carrying out on webbing folding longitudinal edge together.So just formed packing bag round each spring.Last step is the spring that aligns or rotate (30) pocket the inside, comes so that can allow spring expand fully, forms the interior helical spring final length of bag of packing into that (32) couple together.
See also Fig. 2, represented the interior whisker method and apparatus of bag of packing into that one section of manufacturing of the present invention couples together among the figure in more detail.This method and apparatus not only simply but also cheap.This process for making is also very effective and reliable, and can make the outstanding product of quality.The steel wire that is used for this spring is the spring wire of using according to the jewelry of SAE1065-SAE1075 standard, and its diameter is a kind of in following three kinds of diameters: 0.071 inch, and 0.083 inch, 0.094 inch.The tensile strength of steel wire is approximately ASTM 230,000 to 305,000p.s.i..Certainly, should be appreciated that above-mentioned tensile strength is the function of steel wire size and material.Above-mentioned steel wire generally all is placed on push rolls or the supply side reel (50), and on a piped steel support, its length is approximately 79,000 feet or 1800 pound weights steel wire coil.With one group of power rod (51) steel wire is pulled out from above-mentioned support, live roll is with making steel wire send 320 feet speed running to about per minute.The steel wire that is suitable for can be buied from the Insteel Products Co., Ltd in the Andrews city in that state in the southern Caro.
Then, steel wire is by a magneticinduction heating unit or workstation (52).This heating unit is the induction installation of 25KW, can buy from the induction heating device company in the Romeo city of the state of Michigan.This heating unit is made an insulating chest, and its size approximately is long 43 inches, and is high 6 inches, wide 6 inches.This heating unit can make the temperature of steel wire bring up within about 0.63 second between 450 degree F to the 500 degree F.The effect of this heating unit is a stress of steel wire being heat-treated or eliminated it, and the stress relieving that steel wire is produced in manufacturing processed falls, and for winding shaping provides submissive material, thereby reduces the stress that is shaped.This heat-processed is the same with whole technological process, to stop/starting or open/close mode is carried out.Only when moving, just starts by steel wire well heater.When the motion of steel wire paused, heating unit just cut out.The heating that has so just guaranteed each section steel wire is all the same.The heated length of steel wire approximately is 41 inches, and the length of each spring approximately is 9 inches.
Be noted that also and tested other various heat-processedes, but all do not have successfully for above-mentioned Marshall structure.Have been found that these heat-processedes all are both expensive, not only slow but also inconsistent.For example, when stove internal heating in batch, the temperature that has some springs to be heated to is different with the other spring.In another so-called resistive heating technological process, electrode is clamped on the spring that is shaped fully, by means of making electric current produce heat by spring.The quality of this heating technique is decided by whether the electrode and the mechanical contact between the spring that clamp remain the same from beginning to end, and in the high-speed production process, this is the work that is difficult to finish.This method also usually can produce the defective of local superheating and crator and so on.
Stove internal heating in batch needs very big stove, and it is very expensive, and needs extra maintenance management.Produce crator and have in the process for making of fabric encapsulation harmful especially for the back owing to resistive heating.
After the steel wire heating, just move on a building mortion or the shaping work station (54), steel wire at high temperature is configured as spirrillum there.This is by steel wire being pushed to instrument and finishing.Above-mentioned instrument is a kind of steel that has hardened, and its shape is made to make and pushed away nearly its steel wire and carry out bending in continuous and predetermined mode.As a result, with regard to coiled diameter be 2 5/8 inch spiral to be arranged.After whisker is shaped, with one mobile cutting blade is pushed down steel wire and make it cut off steel wire near a fixed blade.Being noted that at steel wire coil can make each spring all carry out " heat " shaping around heating steel wire before.Generally all think, can eliminate steel wire at heating steel wire before the winding shaping step and reduce the stress that produced in the manufacturing processed of its diameter, and this heating steps can allow the forming step of spiral finish under the very little situation of the stress that is produced, because steel wire is at high temperature, under submissiveer state, carry out " processing ".
Through heating, after shaping and the cut-out, spring moves on a refrigerating unit or cooling work station (58), there, each spring all is positioned on the cooling carousel (59) of a circle, and this carousel is rotated in the mode of timing, calibration.Above-mentioned carousel has many narrow slit or openings that are used to hold spring, for example opening (61).
Each spring that is placed on the carousel all passes through preset time in the process of carousel rotation.How much what each spring spent in time on the carousel is the function that needed temperature is fallen.Above-mentioned carousel is designed to support each spring regular hour.The design of this carousel is the function of following various factors: make speed; The quantity of spendable narrow slit, and when carousel is accepted and discharge spring the position of the narrow slit on the carousel.In spring is contained in time on the carousel, perhaps in the portion of time of above-mentioned time, spring will be subjected to the cooling of the freezing air that blows from a blower (57).A kind of function of the size of beginning temperature, opening or the narrow slit of the temperature of the power of above-mentioned blower, the above-mentioned air air capacity whether process is freezed, blown over, air and the speed that other suchlike factors all are the predetermined cooling temperature that will reach, carousel, spring and diameter of carousel or the like.Also may relate to some other factor.For above-mentioned material, require " cooling " to temperature approximately be 150 to spend F.After this, chilled spring moves to a compression set or workstation (60), descends with the air operated piston on this workstation, and each whisker is compressed to about half inch, is ready to it is inserted in the pocket.
The spring temperature that is cooled to about 150 degree F is the function of employed metal, and should be lower than the temperature that can produce tension set when spring is compressed.After this, the spring through overdraft inserts in the fabric pocket; Therefore, what said temperature also must be enough is low, so that be unlikely to burn out fabric.
Except above-mentioned steel wire feeding mechanism, also have a textile material feeding mechanism or workstation (62).One big volume textile material can be pulled out one section fabric along being parallel to the direction that fabric moves.Then, fabric advances to a folding device or workstation (64), and fabric leads thereon automatically, is folded on itself, forms the space that can load above-mentioned spring through overdraft after one.A pair of roller (65) provides motivating force for fabric is pulled out from the supply station.
Then, fabric move to a pack or insert device or workstation (66) on, on this workstation with refrigerative and now through the helical spring motor decussation of overdraft.On this workstation, a cover plate makes spring keep compressed state, and simultaneously, a pushing mechanism slips into by in the folding formed space of fabric each spring through overdraft.Then, the fabric that is equipped with through the spring of overdraft advances to a packaging system or workstation (68).On that workstation, a ultrasonic welding institution lowers, and selectively the fabric of two folded parts, along the direction that is parallel to the fabric travel line and the line perpendicular to the fabric movement direction, links together, and makes a pocket that seals.So just the spring on the line that spring is adjacent has been separated.Another group driving roll (69) is pulled out the fabric that spring is housed from above-mentioned encapsulation work station.
Then, the fabric that spring is housed move to one align or wheelwork or workstation (70) on, on this workstation, the spring in the pocket of packing into that may some expansion comes rotates about 90 degree, make it to expand fully and come that arriving about 6 has 3/4 inch.Above-mentioned rotation and fully expansion be to finish by the blade of a series of rotations, these blades draw past tense to pat these pockets at above-mentioned belt along a chain drive assembly (71).As a result, just finished one section whisker that has in the bag of packing into usual profile, that link together that connects into row's fabric cylinder.
What control above-mentioned technological process and these producing apparatuss is control device (74), and the effect of this control device is, when the some devices of needs are finished some operations on steel wire or on the fabric, in time provides information to each workstation.Like this, the present invention described above approximately has per minute and makes 72 helical spring productivity.Above-mentioned control device also makes whole technological process do to stop/moving, open/close action or do the transposition campaign.
Method and apparatus of the present invention has many advantages.At first, the stress that is added on the steel wire at the steel wire shaping stage has reduced, and the stress that causes in the winding shaping process also is reduced to minimum degree.The second, reduce the performance that these stress have greatly improved spring.Not the needing and do not wish that the distortion that produces has significantly reduced of steel wire, and the life-span of spring has increased.
The 3rd, when the undesirable distortion of spring was reduced or eliminates, the amount of making the durable needed steel wire of whisker had also reduced.Like this, approximately can economical with materials 10-25%.The technology that eliminates stress also may allow the steel wire that uses tensile strength lower, and this provides cost savings again.
At last, the invention provides a kind of heat treatment step, this heat treatment step meets the requirement of flow production line manufacturing process.Very fast of this heating, not contact, and irrelevant with the state of steel wire.As a result, from first to last each spring is in full accord.In addition, it can be applied in the existing manufacturing processed at once.
Present disclosure is described two embodiment of the present invention in detail.According to doctrine of equivalents, other improvement and variation all will fall in claims institute restricted portion.For example, the change of various workstations and device all will be considered to equivalent.Because the material of steel wire has changed and changed temperature, also should be considered to equivalent.Clearly, new technology or other variations also will be equivalents, because, in any case the application of doctrine of equivalents is unrestricted.
A kind ofly be used for making one section and couple together the helical spring method and apparatus in the bag, that use at mat and so on article of packing into.Wherein, the steel wire of sending here from feeding mechanism (10) was heated to 450-500 degree F with induction heater earlier before reeling.Then, steel wire is carried out hot rolling around (18), cut off (20), cooling (22) is to being lower than such temperature again, and tension set will take place for this moment as further processed springs.After this, with spring compression, prepare to insert in the formed space of (26) sending here by a supply side reel of tractile fabric.Above-mentioned space itself is folded up (14) by fabric (12) and is formed.The temperature of spring also must be enough low, lowly its is burnt or cause other damage.After the spring after the compression is inserted above-mentioned space, with ultrasonic welding (28) fabric, for each spring is made pocket independent but that couple together.After this, spring is aligned (30), allow each spring all expand and come, form one section and couple together, the whisker in the bag of packing into.
