Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite press forming machine for processing either wire or strip material, and in particular for processing sequential operations specified by multiple processing plans in multiple directions. Concerning machines improved to be able to accomplish.

A composite stamping machine is an assembly of several machines and tool attachments assembled to produce metal parts by successive metalworking operations according to a specific processing plan.

The operations used in a machining program can vary in complexity and include operations such as punching, punching, swaging, drawing, bending, riveting, and assembling.

The versatility of a given composite press-forming machine therefore depends on the number, sequence and variety of press operations that can be performed with it.

In the past, machines were used to perform multiple metalworking tasks in succession.

However, limitations to all of these machines have occurred, either as to the type, number or sequence of tasks that can be performed.

Most of this type of machine uses a cast mounting base with a fixed length and specific configuration, and because the mounting length and configuration are specific, certain operations can be carried out at a constant distance along the mounting base. It can only be done in position.

Many machines distribute the power for their work from a fixed peripheral shaft located at a certain position on the side of the casting table, but this casting table can only perform press forming work on a specific part of the table. This also necessitates the use of split bearings, which have low precision and are expensive.

Some machines limit the power available for stamping operations by the use of material feeding accessories that take away a high percentage of the total power available for the entire processing cycle.

In many hitherto known machines, the type of work that can be performed is limited because the workpiece must be selected between operations as an integral piece of material.

These machines also limit the number of operations that can be performed, in which case the increase in material feed must be matched to the centerline spacing that exists in the working section.

Most of these machines are configured to process separate workpieces from opposite ends of the stand, but none allow the workpieces to be assembled together in a common operation.

SUMMARY OF THE INVENTION It is therefore a general object of the present invention to provide a composite press forming machine which reduces (or eliminates) the disadvantages of the prior art.

A particular object of the invention is to provide a composite press-forming machine that performs successive press-forming operations according to multiple machining plans, regardless of the number, type or order of operations involved.

The mounting base 12 has a unified mounting for all accessory equipment and is of modular construction as illustrated in FIGS. It can be changed to

In its simplest form, the mounting platform 12 consists of a base module 44 having a fixed length and mounting surface, as shown in FIG.

As shown in FIG. 5, an auxiliary module 46 is coupled to the base module 44 to increase the length and area of the mounting surface in predetermined increments.

The top surface and all exposed sides of the foundation and auxiliary modules 44, 46 are configured with uniform mounting means, such as T-grooves 48, and these means are arranged along the same longitudinal length. It is extending.

If desired, these means can extend the length of the axis in multiple directions.

The auxiliary module 46 and all accessories have mounting means complementary to those of the mounting base 12 and are mounted on the top or sides, or both on the top and sides.

This is illustrated in FIG. 6, where removable support brackets 38 are shown mounted on the sides of the platform, and the frame 50 of a typical progressive die working section 20 is shown mounted on the top and sides of the platform. Shown installed.

Whether the accessory device is mounted on the side or on the top side, or both on the side and on the top side, it can be freely configured in any position depending on the mounting means.

Therefore, metalworking operations can be freely organized according to the order dictated by the machining plan.

An opening groove 51 is present between the transverse ribs 52 on both the foundation and auxiliary modules 44, 46, and
, making it possible to finish the workpiece at any position.

The general use of a unified mounting means on the mounting platform 12 for installing certain accessory equipment or for interconnecting the foundation and auxiliary modules 44, 46 is illustrated in FIG. The installation of removable support bracket 38 is specifically shown.

A bolt 53 is placed through the removable support bracket 38 and secured to a mooring nut 54 located in the T-shaped groove 48 on the mounting base 12.

A cylindrical spacer 56 connects the gear box 58 and the bracket 3.
8, the mooring nut 54 is free to
The bracket 38 slides within the shaped groove 48, and the bracket 38 is attached to the mounting base 12.
Installation is possible at any position along a side.

Bracket 38 can therefore be separated from gearbox 58 by the width of one or more metalworking operations if necessary to accomplish a given machining plan.

Each bracket 38 is one piece.
E construction and is configured to mount a single piece precision bearing 60 by any suitable means such as a tight fit.

If the pedestal 12 is configured with multiple modules to accomplish a particular machining plan, the brackets 38 may be positioned as desired along the pedestal 12 supporting the peripheral shaft 28.

Thereafter, simply attach the bracket 38 with the bearing 60 to the base 1.
By sliding it along the two unified installation means, it can be rearranged as needed to change to another machining plan.

As is conventional, the combination of both horizontal slider 61 and vertical slider 62 is configured to concentrate on the workpiece in slide forming station 24.

However, in this composite press forming machine 10, forming can take place at certain selected locations along the fixture 12.

To do this, a vertical slider 62 and a horizontal slider 61 acting across the groove 51 are inserted at certain selected locations along the mounting platform 12 as illustrated in FIGS. 19 and 25. Installed in T-slot 48.

Horizontal slider 61 that acts along the length of the mounting base 12
is located within the groove 51 as shown in FIG.
It is configured to be continuously adjustable in length for operation at selected locations along the pedestal 12.

An intermediate link 63 arranged between the ends of the horizontal slider 61
Any suitable means may be used to make this length adjustment, such as.

Reaction forces are transmitted through the material as operations are performed on the material, and this force causes the material 16 to move relative to the processing line.

To prevent this movement, it is appropriate to incorporate a material stopping attachment 18 across the processing line as illustrated in FIG.

The material stop attachment 18 used in this invention differs from conventional material stop attachments in that it rotates the spline 64 in a timed relationship with the stop action on the material 16.

Rotation of this spline is used to initiate the gripping action of the material feed attachment 14, as will now be discussed in detail herein.

In a typical configuration, the material stopping attachment 18 connects the fixed shoe 65 and the movable shoe 6 as shown in FIG. 14 when the movable shoe 66 contacts the left side of the material 16.
6. Grip the material between 6 and 6.

The movable shoe 66 is attached to a follower link 68 which is disposed within the stop housing 70 and biased by a spring 74 to follow the hill portion of the swing arm 72.

Swing arm 72 is pivotally connected to stop housing 70 at one end by suitable means such as pin 75 and has a roller 76 secured to the other end.

This roller 76 follows the hill of a cam 78 driven by the peripheral shaft 28.

The locking shoe 65 contacts the right side of the material 16 and is secured to a link 80 that connects the stop housing 70 to have an appropriate length to position the locking shoe 65 with respect to the various material 16 thicknesses. located within.

A swing arm 82 is pivotally connected to the housing 70 on the right side of the platform 12 by suitable means such as a pin 83.

One end of this swing arm 82 is pivotally connected to a first end of a link 84 whose length is adjustable by suitable means such as a pin 85.

The second end of the length-adjustable link 84 is pivotally connected to the first end of the conversion link 86 by suitable means such as a pin 87.

At its second end, a conversion link 86 is secured to the spline 64, the spline 86 being rotatably disposed through the stop housing 70 by suitable means and extending therefrom in the direction of the material supply attachment 14. .

A roller 88 is rotatably mounted to the other end of swing arm 82 by suitable means.

A cam 90 is secured to one end of the peripheral shaft 28;
The roller 88 is arranged so as to follow the hill portion of the cam 90.

The stop housing γ0 is also configured to provide structural support for the ends of the two guide rods 92, and is configured to provide structural support for the ends of the two guide rods 92.
extends therefrom in the direction of the material supply attachment 14;
And this will be discussed further later.

When the machine 10 is in operation, the material 16 moves along the processing line past between the fixed and movable shoes 65° 65 of the material stopping attachment 18.

When the cam γ8 rotates, the cam γ8 causes the rocking arm 72 to rock about the pin 75, and when this rocking movement is performed in a clockwise direction, the follower link 68 moves the movable shoe 66 towards the fixed shoe 65. and the material 16 is gripped between them.

At the same time, the cam 90 rotates in a direction that causes the swing arm 8.2 to swing counterclockwise about the pin 83,
This, in turn, causes the length-adjustable link 84 to drive the conversion link 86 counterclockwise.

Spline 64 follows the movement of direct translation link 86 and therefore rotates in a counterclockwise direction where material feed attachment 14 releases its grip on material 16, as will be explained later in this specification.

When the rocking movement of the rocking arm 72 is performed in the counterclockwise direction,
The material 16 is released from the material stop attachment 18 and at the same time the swing arm 82 swings clockwise causing the material feed attachment 14 to grip the material 16 during clockwise rotation of the tin.

The material supply accessory 14 uses a reciprocating material supply carriage 94 to supply the material 16 to the processing line as shown in FIGS. 7, 10-13.

The material supply carriage 94 is housed within a carriage housing 96 having a cavity 98 configured to accommodate a gripping mechanism 100 such that a positive gripping action on the material 16 by the gripping mechanism 100 is achieved by the gripping mechanism 100. ~13 is performed as illustrated in FIG.

The perforated groove 102 has a perforated portion so as to communicate with the cavity 98, and passes through one side of the movable carriage.

In three directions, a cylindrical passageway 104 is disposed through carriage housing 96 with a centerline parallel to the centerline of slotted groove 102 .

A bushing 106 is inserted at both ends of each passageway 104, and the guide rod 92 referred to in the description of the material stop attachment 18 is inserted through the two passageways 104 and slides freely therein.

The spline 64 described as part of the material stop attachment 18 is inserted through the third of the passageways 104 and is positioned within the carriage housing 96 such that the lubricant conduit 108 is in communication with all three passageways 104. There is.

The gripping mechanism 100 includes a guide rod 92 or a spline 6.
4 is assembled into the cavity 98 of the carriage housing 96 before being inserted into the carriage housing 96.

As shown in FIG. 12, the roller link 110 of the gripping mechanism 100 is configured with a splined hole by suitable means such as a splined housing 112. As shown in FIG.

Radially from this splined hole, the roller link 11
0 is pivotally attached to the first end of translation link 114 by suitable means.

The second end of conversion link 114 is pivotally connected to the first ends of both extrusion link 116 and tow link 118 by suitable means such as pin 120.

At its second end, a push-out link 116 is pivotally connected to a gripping shoe 124 by suitable means such as a pin 122;
The gripping shoe 124 is disposed within a slotted groove 102 of the carriage housing 96 and freely slides within this groove 102.

At its second end, the traction link 118 is attached to a pivot block 12 which is adjustable by suitable means such as a pin 126.
8, the pivot block 128 extends from a cavity 98 in the carriage nozzle 96 and is arranged to slide freely therein.

The second end of the pivot block 128 is located outside the cavity 98 and is configured with a wedge head 130 with an inclined surface.

A wedge block 132 (inserted below the wedge head 130 and adjustably secured to the carriage housing 96 by suitable means, such as a tether bolt 134) has an inclined surface that matches the inclined surface of the wedge head 130. There is.

A support plate 136 is mounted to carriage housing 96 over slotted groove 102 by suitable means such as bolts 137.

As previously discussed, guide rods 92 and splines 64 extend from material stop attachment 18 and are connected to carriage housing 96.
is arranged to pass through.

Spline 64 must be aligned to pass through splined bushing 112 in roller link 110 of toggle mechanism 100 when inserted through carriage housing 96 .

The guide rod 92 and the spline 64 are connected to the movable base housing 9.
6, they are aligned parallel to the processing line and placed on the mounting base 1 as illustrated in FIG.
It is supported within the support extension 138 of 2.

Reciprocating motion with a variable stroke may be imparted to the material feed carriage 94 from an eccentric of some suitable construction.

A gear drive body 140 connects the peripheral shaft 2 via a gear 142.
One such structure is illustrated in FIG. 10, driven in rotation by 8.

Follower link 144 is pivotally mounted at selected locations along radial T-slot 146 of gear drive 1400 by suitable means.

Follower link 144 actuates a lever 148 hinged to support extension 138 at a first end by suitable means such as a bearing 149.

At its second end, the lever 148 is connected to the first link 150 whose length is adjustable by suitable means such as a pin 151.
It is pivoted at the end.

The second end of adjustable length link 150 is attached to V-link 152 by suitable means, such as a connecting screw.

The V-link 152 is pivotally connected to a tongue 153 on the carriage housing 96 by suitable means such as a pin.

In operation, the material supply attachment 14 is activated by the material stop attachment 18.
and thereafter feed material 16 from storage reels along the processing line according to the processing plan.

The material supply carriage 94 is reciprocated by the guide rod 92 and the spline 64 with a stroke equal to a predetermined supply payout amount, and the gripping action of the material supply carriage 94 is in the direction of the material stop attachment device 18. The stroke is synchronized to convey the material 16 to.

At the beginning of this stroke, material feed carriage 94 is spaced apart from material stop attachment 18 and actuated by spline 64 to grip material 16 .

The material feed carriage 94 then advances toward the material stop attachment 18 to the end of its stroke, at which time it is actuated by the spline 64 to release the material 16.

Then, the material supply moving table 94 is moved without being affected by the position of the material 16).

- Return to the initial position at the start of the process and - complete the machining cycle.

The amount of increase in material payout is determined from the increase in the interval existing between the operations performed on the material 16 in the processing line and is equal to the amount of increase.

The gripping mechanism 100 within the material feed carriage 94 is best understood with reference to FIG.
02 acts to grip the material 16 placed within it.

When the spline 64 rotates clockwise, the material feed carriage 94 grips the material 16.

During such rotation, roller link 110 also rotates clockwise causing translation link 114 to reposition pin 120 and the first ends of both extrusion link 116 and traction link 118 in a downward direction away from spline 64. Cause.

This changes the spacing between pins 122 and 126 from pins 122 and 126.
It will increase along the center line passing through 6.

The position of the pin 126 is fixed below the wedge head 130 (along this centerline by the relative insertion of the wedge block 132, and then the gripping shoe 124 is attached to the support plate 136).
are forced toward the material 16 to grip the material 16 between them.

When material feed carriage 94 is actuated to grip material 16, negligible torsional deflection occurs along the length of spline 16 as a result of its stiffness.

Therefore, the gripping force applied to the material 16 maintains the material 16 throughout the material feed carriage 940 stroke.

The grip on material 16 is released from material supply carriage 94 when spline 64 is rotated counterclockwise.

This causes roller link 110 to reposition pin 120 and the first ends of both extrusion link 116 and traction link 118 in an upward direction toward spline 64 .

The spacing between the pins 122 and 126 is thereby reduced, this spacing being such that the gripping shoe 124 can grip the material 16 and the support plate 1.
This is a result of the movement away from 36.

The gripping pressure for materials 16 of various thicknesses is determined by the gripping shoe 1
24 and support plate 136 prior to operation of machine 10.

This is done by changing the position of the fixed pivot point of the pin 126 by adjusting the mooring bolt 134, thereby locking the wedge block 1 relative to the wedge head 130 of the pivot block 128.
Achieved by changing the arrangement of 32.

As illustrated in FIG.
The reciprocating motion of is caused from the gear drive 140 by a follower link 144, which
8 is periodically moved in an arc around the bearing 149.

The arc movement of the lever 148 allows the link 15 to obtain the length.
0, the link 150 converts an arcuate motion into a linear motion at the U-link 152 portion as a result of the forcing action exerted on the carriage housing 96 by the guide rod 92.

Since the circular arc movement is performed periodically, the linear movement is also performed periodically, and the material supply carriage 94 reciprocates along the guide rod 92 with a predetermined stroke equal to the amount of material dispensed.

The reciprocation of the stroke can be adjusted by changing the position of the pivot connection between the gear drive 140 and the follower link 144 along the radial T-slot 146.

The installation of the metal piece transfer attachment 26 into the machine 10 is the fifteenth step.
18 and 20 to 26.

In a typical configuration, the metal piece transfer attachment 26 comprises a rail 154 positioned along the processing line;
The rail 154 includes a plurality of pairs of finger member assemblies 156,
It is fixed across the processing line.

Each pair of finger assemblies 156 cooperate to hold a piece of metal 158 between them as shown in FIG. A number of pairs of bodies 156 are shown spaced apart on the processing line with constant incremental spacing X.

Along the processing line, the metal pieces 158 are transported in rows (all working stations are similarly spaced apart at constant incremental intervals X, and each pair of cooperating finger assemblies transfers two
It reciprocates to move between two working sections.

The rail 154 is rigidly secured to one end of the machine by a drive bridge 160.
is driven forward from the peripheral shaft 28 with a stroke equal to the constant incremental interval X, as shown in FIG.

As shown in FIGS. 15-18, the rail 154 is supported in a channel block 162 along the top surface of the mounting platform 12, and the channel block 162 is supported by bolts 165.
It is attached to the bracket support 164 by any suitable means such as.

Clearance is provided in the channel block 162 so that the rail 1
54 is adapted to slide within it.

A shoulder groove 166 runs the length of each rail 154 within which a mooring nand 167 is positioned for mounting the finger assembly 156.

In each finger assembly 156, a finger 168 includes:
It is slidably mounted within the finger block 170, as shown in FIG. 17, by suitable means such as pins and slots, not shown.

A spring 172 is disposed within the finger block 1γ0 to bias the finger 168 toward the metal piece 158.

Each finger block 170 has a pair of slots 173;
Through this slot 173 each finger block 170 is secured to the key block 1 by suitable means such as a bolt 175.
Adjustably mounted to 74.

As illustrated in FIG. 16, this adjustment allows the finger assemblies 156 to be spaced across the processing line to accommodate metal strips 158 of different widths.

Finger block 170 has a flat stepped portion 116 into which the mating portion of the key block fits without relative rotation.

A tongue 177 across the surface of the key block 1740 has a width that matches the shoulder groove 166 of the rail 154 and is secured by a bolt 178 of the tether nut 167.

The tip of each finger-like member 168 allows easy insertion of the metal piece 158 (
is shaped to facilitate the withdrawal of the metal piece 158 from the cooperating finger device 156, and has a notch 180 shaped to do so.

Reciprocating motion is applied from an eccentric of some suitable construction to a drive bridge 160 that interconnects the rails 154 of the metal piece transfer attachment 26.

One such arrangement is illustrated in FIG. 26, in which the first end of drive link 182 is connected to drive bridge 1 at a point between rails 154 by suitable means such as pin 183.
It is pivoted to 60.

At its second end, the drive link 182 is pivotally connected to the first end of the drive lever 184 by suitable means such as a pin 185.

At its second end, a drive lever 184 is pivotally mounted to a support bracket 186 by suitable means such as bearings 187.

Support bracket 186 is securely secured to mounting base 12 by uniform mounting means in the same manner as previously described.

A roller 188 is pivotally mounted along the length of drive lever 184 such that its surface contacts cam 190 , which is driven by peripheral shaft 28 .

Each station that receives a metal piece 158 is provided with means for handling the metal piece 158 between its location within the cooperating finger assembly and the working metalworking position.

These handling means may vary depending on the type of work being performed, but generally the handlers move toward each other and along a common center line, thereby gripping the piece of metal 158 between them. by placing appropriate stripper pins across the section.

After the metal piece 158 is gripped between opposing stripper pins, the metal piece 158 can be manipulated into or out of the finger assembly 156.

The stripper pin is driven by the peripheral shaft 28 via a cam and a suitable linkage, and the handling operations of the stripper pin are therefore successively occurring at precise time intervals during the machining cycle.

In operation, the metal piece transfer attachment 26 serves to transfer the metal pieces 158 stamped from the material 16 to the next work station, where the material 16 is transferred to the material supply attachment 1.
4.

This involves placing the metal piece 158 into a pair of finger assemblies 156 upon completion of the progressive die operation 20, and moving the metal piece 158 between the workpieces according to the remaining machining plan into the pair of finger assemblies 156.
This is achieved by transporting the metal piece 158 by means of the metal piece 56.

Each pair of finger assemblies 156 reciprocates between two press and/or forming operations, and therefore each metal piece 158 is successively moved by each pair of finger assemblies along the processing line. is transported in constant incremental movement widths.

The reciprocating motion of the metal piece transfer attachment 26 is caused by a cam 190 via a roller 188, and this reciprocating motion causes the drive lever 184 to periodically move in an arc about a bearing 187.

The arcuate motion of the drive lever 184 is applied to one end of the drive link 182, which transforms the arcuate motion into a linear motion at a pivot pin 183 on the drive bridge 160 as a result of the forcing action exerted on the rail 154 by the channel block 162. Convert.

As the arcuate motion is periodic, the linear motion is also periodic, and the rail 154 reciprocates within the channel block 162 with a predetermined stroke.

This reciprocating motion is transmitted directly to each pair of finger assemblies 156 which are rigidly secured to the rails 154.

Stroke variation is generally accomplished by replacing the cam 190, but it is also possible to change the position of the pivot pin 185 and/or roller 188 along the length of the drive lever 184, such as a slot. Any other suitable means of using the material may also be used.

In each operation, the stripper pins converge across the processing line to firmly grasp the metal piece 158 and manipulate it into or out of the cooperating finger assembly 156.

This gripping action by the stripper pin is continuously timed to match the reciprocating motion exerted on the cooperating finger assembly 156 such that at each work station, the metal strip 158 is removed before the work is completed. , a pair of cooperating finger assemblies 1
56 and picked up by another pair of cooperating finger assemblies 156 after the task is completed.

Therefore, at the beginning of each machining cycle, each pair of cooperating finger assemblies in which the metal piece 158 is placed is pre-finished (p

Then each pre-performance

Then, each post-performance
e) in the operation, the stripper pin converges on the metal piece 158 to remove the metal piece 158 from within the processing equipment at the operation;
Disposed within a cooperating finger assembly 156.

Each pair of finger assemblies 156 in which metal pieces 158 are disposed is then used for pre-preformance when a machining cycle is started.
You can move forward with your work.

During transport, the metal piece 158 is inserted into the notch 180 of the finger 168.
between each pair of cooperating finger assemblies 156 and held in place by opposing forces applied by springs 1γ2.

When the metal piece 158 is manipulated into or out of the cooperating finger assembly 156, a lateral force is applied to the metal piece 158 by the stripper pin; the notched surface of the shaped member 168.

Each finger 168 resists the biasing force of a spring 172 until the spacing between cooperating finger assemblies 156 is sufficient to allow a piece of metal to pass laterally between the finger assemblies 156. It is resisted and retracted into the interior of the finger block 170.

As in the prior art, the material feeding accessory 14 is configured to process two separate products in converging directions along the processing line (
attached to each end of the machine 10.

This technique supplements the processing line with a metal piece transfer attachment 26 that operates in each direction, and the metal piece 15 of each product.
