Bender is a kind of for the metallic plate of relative thin to be bowed out into a representative machine simply rolled over every time.Because This machine be used to bend metallic plate thin slice, and the power being applied on work piece is then relatively small.The machine can be by easily Change with conversion rate and stroke height (drift travels down to the length of work piece and punch die).Mould for bender (tool) it is standard, and can be quickly mounted and dismantle.Bending machine die is typically with respect to lightweight and can taken with hand Rise.In bender operation, three points are generally only touched in stroke lowest part work piece, these three are touched point and come from The center of top of drift and the bottom of the shoulder of punch die two.Power press is used to punch by the metal bending of relative thick or above.It is dynamic The power for forcing machine application is much larger than the power that typical bender applies.Power press is arranged to good tolerance, for example, dynamic The mould in machine is forced to be installed on slideway to ensure that they are always in the same position relative to other moulds.Power Diel --- including punch die and drift --- is fixedly mounted on the machine, and it is small that the process can expend 1 easily When or it is longer.The mould is made up of dexidized steel (solid steel) and weighed very much, it is often necessary to which special equipment gives rise to them Position.In power press stroke lowest part, work piece is generally sandwiched between drift and punch die, i.e., all not had Anywhere completely Gap.

In power press, the radius of mould shoulder is generally determined by the thickness of work piece.The dicoration of work piece Outward appearance is in general hardly important.Power press be generally used for repeat pressure operation --- a machine can be completed for one day 10000 same operations, day by day.Power press is not generally used for the disposable bending for making metallic plate.

Mould in power press is usually by thermally treated and hardening special tool steel (specialist Tool steel) it is made.High-carbon steel can be hardened by first heating after steel quick cooling steel.The steel are then added again Heat arrives low temperature and being capable of Slow cooling.Sometimes screwed hole can be got out in hardened steel dies.But so do it is being extremely difficult to and Expensive.Change hardened steel dies generally higher than getting out the cost performance of screwed hole in a mold.

Constantly repair or maintain highly difficult workspace (the hardest of the metal forming mould for power press Worked areas) it is a problem.The highly difficult workspace of mould is generally in shoulder.Shoulder damage is dragged by work piece Work piece is dragged across by shoulder or shoulder and is caused.Substantially, the damage is the frictional force between two surfaces Cause, the frictional force produces the microscopic level heat for melting some surface particles enough and then further results in periphery surface Damage.Determining the factor for the amount of damage that mould can be born includes:

The performance of work piece material;

The pressure applied between mould shoulder surface and work piece;

The speed that work piece is pulled on mould shoulder or mould shoulder is pulled on work piece;

The amount and quality of lubricant between surface;

The quality of mold materials;

The surface smoothness of both work piece and mold materials;

Work piece surface and the substantially cleanliness factor of mould shoulder surface;

Other secondary causes, such as room temperature;

Productivity ratio (number of times of mould is more per hour, then needs the more frequently more mold exchange because of damage).

The purpose of a preferred embodiment of the present invention is at least to solve shoulder or mould shoulder to a certain extent Damage problem.When the purpose is applied to preferred embodiment, it should be appreciated that not restricted claim protection model The plan enclosed.Because goal of the invention inherently in order to give the public provide a useful selection.

Embodiment

Fig. 1 shows the power diel with punch die 2 and drift 3 under three kinds of states in use.Left side is regarded Figure shows that preparation is moved down into the drift 3 on work piece 4, and the work piece 4 is in the form of metal material sheet It is placed on punch die 2.Middle view shows the drift 3 after just being contacted for the first time with the work piece 4.Right side View is shown, when the drift is completely in die cavity 5 and causes work piece 4 to be adapted with the cavity shape The power diel.Reference picture 2, the shoulder 6 of punch die 2 is subject to substantial amounts of abrasion, and these abrasions are included with drift 3 Oppress the power that work piece 4 applies by shoulder via work piece 4.Work piece may also be subjected to be pressed through The shoulder 6 of punch die 2 and produce scuffing.These scuffings need to remove by sbrasive belt grinding (linishing).Sbrasive belt grinding is related to Mill or belt sanding affected area is to improve surface smoothness.Sbrasive belt grinding may also design surface polishing.However, in Fig. 3 The diel 1 shown has the feature (Fig. 1 and Fig. 2 not shown in) for solving this problem.

Reference picture 3, each shoulder of punch die 2 has the detachable wear-resisting roller assembly 7 of an interference fit.It is described Roller assembly 7 slips into the shoulder 6 of punch die with an angle, and the angle divides the interior angle (internal angle) of punch die equally, and The roller assembly 7 provides a roll bending edging (rolling curved wear for being used to contact the work piece 4 edge).Angle of the roller assembly 7 on punch die shoulder, preferably divides the interior angle (included of punch die shoulder equally Angle angle).In this case, the interior angle of punch die shoulder is about 45 ° for the angle of 90 ° and roller assembly.For the ease of Roller assembly is installed in punch die, and there is roller assembly longitudinal groove 7a (referring to Fig. 4 and Fig. 5), longitudinal fluting 7a to be configured to It is adapted with the complementary projection (not shown) in die body.In some embodiments, the roller bearing extends to the side of punch die Edge.Rolling (rolling edge) 8 make the work piece 4 roll across from it and avoid edge it is static when can caused by point it is curved Bent (point loading) situation.

Optionally, the roller assembly can coordinate the complementary die cavity in drift and/or punch die for arbitrary suitable shape. Fig. 9 shows the different embodiments for the roller assembly 7 that can be used.Although Fig. 4, Fig. 4 A and Fig. 5, which are shown, to be had and complementation Projection adaptation groove 7a roller assembly, it is to be understood that they for each embodiment of roller assembly 7, It is not essential.For example, Fig. 9 roller assembly 29-33 and without groove.The roller assembly is arbitrary suitable shape Shape is possible to coordinate the complementary die cavity in drift 3 and/or punch die 2.Suitable shape refers to, in the plane from roller bearing to pedestal With prismatic shape (such as shown in Fig. 9), and can be by interference fit on drift and/or punch die.For example, rolling Shaft assembly 7 has projection and there is complementary channel to be possible for the drift and/or punch die.As shown in figure 9, the one of roller assembly A little embodiments have pedestal more broader than roller bearing portion.Other embodiment (such as roller assembly 27 and 28), which then has, matches somebody with somebody syzygies First 3 and/or the groove of the complementary projection in punch die 2.Each roller assembly both is set to the complementation with drift 3 and/or punch die 2 Die cavity formation interference fit.As shown in figure 9, the shape of roller assembly bearing can change.In a preferred embodiment, institute Stating roller assembly bearing has at least three different surfaces, described at least three different surfaces and punch die 2 or drift 3 Ipsilateral formation is not interference fitted three of die cavity.As shown in figure 9, some bearings can have and corresponding table in drift 3 or punch die 2 Face forms the more than three different surfaces of interference fit.

Rolling 8 means that work piece 4 no longer scrapes the shoulder of punch die 2.Due to punch die 2 shoulder and work piece 4 it Between frictional force reduction, shaping work piece required for power, it is smaller during static shoulder than being set on punch die 2.Using rolling Side 8 also reduces the scuffing on work piece, it is meant that sbrasive belt grinding work piece is notable the need for shoulder is damaged to reduce Reduce or be excluded.

More detailed wear-resisting roller assembly 7 is shown in Fig. 4-8.Especially as shown in Figure 4 A, roller assembly 7 includes bearing 9, the bearing 9 has the top edge in the form of support 10.It is located in the bar-shaped roller bearing 11 of metal in the support 10, the rolling The cross section of axle 11 is circle.The bearing and roller bearing are preferably by bearing compatible material (bearing compatible Material) it is made.The material used can be influenceed by the particular job and required function for needing to complete.It is preferred that combination Can be phosphor-copper bearing and hardened steel roller bearing.

In a preferred embodiment, the roller bearing is fabricated by by hardened steel.In these embodiments, drift and/or The other parts of punch die may be by more the hard, material manufacture that need not be hardened inexpensively is not formed.If drift and/or Punch die can be formed by material manufacture inexpensively, then can be existed in cost, processing and on delivery cycle (lead time) potential Reduction space.

The roller bearing is supported in the bearing by clip 12.The clip 12 is removably attached to the slit of bearing In 13, and it is engaged with the groove 14 of roller bearing 11.This arrangement mode enables roller bearing 11 to be rotated when in support, with Work piece reduces fretting wear when moving through it because of the pressure from drift.The roller bearing 11 may or may not be hollow 's.In some embodiments, there may be multiple clips, they are all installed in the same fashion and with spaced relationship, this depends on In the length of rotating shaft 11.Fig. 4 A show the embodiment with two clips, respectively in two ends of roller bearing.Clip 12 is helped Help and keep position of the roller bearing in bearing 9, and provide the connection of roller bearing and bearing to prevent roller bearing relative to bearing along its rotating shaft It is mobile.Lubricating system also solves wear problem.Reference picture 4A and Fig. 5, the bearing 9 are respectively provided with passage 15 in each end.Such as Shown in Fig. 7, the passage 15 leads to support 10.Lubricant can be injected into the passage so that it reaches support, to the rolling Axle 11 provides the abrasion and loss for lubricating and further reducing roller assembly 7.

Reference picture 12, in certain embodiments of the present invention, the roller bearing 11 can at one end or its surface other portions On position have ditch flute profile mark line 11a so that operator can easily observe it whether as it should it is in use Rotate.If it is not rotated, operator can impose more lubricants by passage 15, and/or, dismantled to investigate rolling The reason for axle stops the rotation.

Figure 10 A show that (for convenience of description, some foregoing features are omitted when roller assembly 7 is installed in place ), the contact situation between the work piece 4 and punch die 2.It can see from Figure 10 A, the mould with bearing and roller bearing and not Mould with bearing and roller bearing, with identical appearance and size (overall dimension).Extra sheet material or tight is not needed Firmware.The roller bearing extends the length of punch die 2.The roller bearing does not have nose portion.The roller bearing and bearing can be contained in mould The end of tool.The work piece contact surface provided by roller bearing is similar with the contact surface of common power diel.Figure 10 B Another embodiment of work piece and punch die 2 is shown, wherein the second of roller assembly 7 embodiment has been installed to Position.If roller bearing 11 weares and teares over time, it is not necessary to by drift 3 and/or the integral replacing of punch die 2 or to drift 3 and/ Or punch die 2 largely handle to recover its shape, roller bearing 11 is with regard to that can be easily replaced.For example, if it is necessary, not overall Drift and/or punch die 2 are changed with regard to the entirety of roller assembly 7 can be changed.Optionally, bearing 9 can be retained and only roller bearing 11 is by more Change.

Roller bearing is changed to can relate to dismantle the roller assembly 7 from drift 3 and/or punch die 2.The dismounting of roller assembly, can Realized by the way that roller assembly is skidded off from the die cavity of drift 3 and/or punch die 2.It may need to apply certain power, will rolling Shaft assembly is skidded off from drift 3 and/or punch die 2.Once being disassembled from drift or punch die, new roller bearing 11 can be installed to Slipped back on roller assembly 7 and by roller assembly in drift 3 or punch die 2.In some cases, institute is not dismantled from power press The replacing can also be realized by stating drift or punch die.Because the roller assembly 7 can by the way that part is gone out from drift or punch die or Skid off and then slip into drift or punch die to change by new part, change involved skill seldom.Because need not be skilled Craftsman, which reduce the cost for changing part.

In addition, drift and/or punch die can be changed, so that the roller bearing and bearing are modified by being installed to punch die or punch die On.Although it is unpractical that screwed hole is got out in hardened steel drift or punch die, steel wire corroding machine (wire erosion are utilized Machine the die cavity or slit) cut out for roller bearing and bearing is possible.Steel wire corroding machine was in twentieth century 60 years In generation, is just developed success, and can be used to cut hardened steel dies.Steel wire corroding machine can cut out type in hardened steel dies Chamber --- including the die cavity damaged in shoulder regions --- is so that roller assembly is modified by being installed on mould.Steel wire is rotten The accessible accuracy of erosion machine, it is meant that it is cleavable go out with roller assembly be interference fitted die cavity.Because roller bearing or roller bearing and branch The combination of seat can be replaced in abrasion, compared to more mold exchange in itself, and remodeling bearing and roller bearing have a clear superiority.In mould When being just made, the die cavity for roller assembly can be also formed.May be slightly although cutting out die cavity in drift 3 or punch die 2 Reduce the intensity of power diel, still can apply similar maximum pressure per square inch.In a word, pacify in roller assembly When being attached to, the power needed for work piece shaping will be less than power required during without roller bearing;Because, work piece into During shape, roller bearing reduces the amount of friction produced between work piece 4 and drift 3 and/or punch die 2.

Referring again to Fig. 3, in some embodiments, the drift 3 is contacted at shoulder thereunder, can be had and be adapted to Dismountable wear-resisting mold insert 16 of friction.They have radius shape edge and the abrasion produced are contacted with work piece 4 to reduce.Punching The mold insert 16 of head can be disassembled or change when being damaged, and without changing the miscellaneous part of drift.Mold insert 16 can be by hardened steel Or coated steel (coated steel) is made, it is meant that the main body of drift can by it is more not hard, inexpensively and be not required to be hardened Material be made.Mold insert 16 is different from roller assembly 7, does not have roller bearing 11 in them.However, in some conversion embodiments In, drift mold insert can shape and operate as punch die roller assembly 7.In other embodiments, abrasion be not a problem but When the slip of work piece is a problem, drift mold insert 16 can be zigzag, preferably to firmly grasp it when handling work piece.

Certain aspects of the invention, many selections can with the completion different task of roller assembly 7 and mold insert 16 are every kind of Selection is made from a different material, or with the part contacted with work piece being made from a different material.

Reference picture 11 a, alternate embodiments of the invention can have solid integral mold insert 17 --- i.e., do not have Roller bearing 11.The need for particular task, they can be made up of the material with different qualities (such as coefficient of friction), and can It is easily replaced by abrasion.

Based on another embodiment, Figure 13 and Figure 14 show the roller assembly for punch die or drift.In such case Under, roller bearing 18 is maintained in the support 19 of bearing 20, without using shape of a hoof clip.More precisely, roller bearing 18 via The holding plate 21 that spiral is fixed on the two ends of support 19 is kept.The dop (stub) 22 at the two ends of roller bearing 18 and 23 points of the hole of holding plate 21 Clamping Pei not merged.When the interior angle of drift or the shoulder of punch die (roller assembly is mounted thereon) is approximately less than 70 degree, roller bearing This connected mode is particularly useful;In this case, bearing is less than 180 degree around the angle of roller bearing, so can not be by Its perpendicular positioning.In the embodiment shown in Figure 13 and Figure 13, holding plate provides the approach of connection roller bearing and bearing, to prevent Only roller bearing had not only been vertically moved relative to bearing but also moved along its rotating shaft.Existed in the manner shown using another benefit of holding plate In holding plate is only by roller support on bearing.They do not fix roller bearing relative to drift or punch die, it is meant that need not be Screwed hole is got out in drift or punch die.As it was previously stated, it is uneconomic that screwed hole is got out in hardened steel drift or punch die.Due to Holding plate is attached on bearing, and this problem just overcomes.Reference picture 15, in some embodiments, diel can make With drift 23, the drift 23 is moved towards the work piece 24 being arranged on punch die 25, and the punch die 25 does not have die cavity.It is described Drift 23 has dismountable roller assembly 26, in turn, and the roller assembly 26 has removable as described in other embodiment Unload roller bearing.Figure 16 and Figure 17 shown when drift 23 is used to shape work piece 24, after the activation stage one by one of phase rush First 23.

Figure 18 shows an embodiment of mould, and wherein punch die 2 and drift 3 is provided with roller bearing in their shoulder Component.The friction that the shoulder of the setting of multiple roller assemblies, it is meant that during shaping operation, punch die 2 and drift 3 is subjected to is notable Less than the friction being subjected to using static punch die and punch shoulder.Roller bearing decreases the cut on the work piece of shaping.

Although describing some preferred embodiments of the present invention by way of example, it should be appreciated that do not departing from appended power It can modify and improve in the case of the scope that profit is required.
