Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for continuous pressing of sequentially supplied materials, in particular an interchangeable mounting with progressively varying pitches within a common housing structure. The present invention relates to a device for integrating a tool drive slide and a support member.

Traditionally, many machines are known for performing a series of presses to produce complex parts from sequentially fed materials, but the utility of this type of conventional machine is limited by the pitch of the press That is, installation depends on the ease of changing the distance between locations, the order and/or characteristics of the pressing operations, and the number of operations.

The most common technique for performing such press operations is to use a progressive die that houses a series of press operations within a mask housing that can be simply set into the manufacturing machine.

However, this progressive die is not only extremely expensive, but also the number of press work steps is basically fixed, making it impossible to provide versatility according to the characteristics and order of the press work. Therefore, there are deficiencies that can only be exploited in mass production processes.

Another type of press machine is one that is equipped with a number of stationary stations that allow it to carry out different pressing operations, even if the nature and order of the operations change, and which therefore exhibits versatility even for operations that are not particularly mass-produced. There is something.

However, each work in this type of machine is performed in a separate structure, and each work station is mounted at a fixed pitch, which makes it lacking in versatility.

Furthermore, some press machines allow the mounting pitch of each work station to be changed in response to changes in the characteristics and sequence of various press operations, but even in this case, an individual housing structure is required for each press operation, and therefore There is a drawback that the space required for the press processing line becomes large and the number of work steps is limited.

Furthermore, in a machine that uses a sliding body that drives a tool from a peripheral shaft and a support member that receives a press load from the shaft, there is no possibility of interchangeable pitches between the sliding body and the support member. Therefore, there is a limit to the degree of distribution of the sliding body and the supporting member along the press working line, and the bending of the drive shaft makes it difficult to increase the flexibility of the press work plan.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a press apparatus that can avoid the problems caused by the prior art as described above.

Another object of the present invention is to provide a press apparatus that integrates a tool drive slide and a shaft support member in an interchangeable mounting location within a common housing structure.

According to the invention, these objects are achieved by arranging the jib base and the support member on the mask housing with a plurality of mounting locations spaced apart from each other at a constant pitch distance.

The pitch distance of the jib base or support member can be incrementally changed in multiple steps.

Also, mounting of the mask housing is comparable to mounting means where the mounting means is disposed on the jib base or support member.

Each jib base has the thickness required by a tool that guides the slide and is fixable to a standard holding device on the slide.

Each support member extends from the mask housing to allow the press machine to receive the press load from the drive shaft, and has a pitch of mounting required depending on the magnitude of the press load.

The mask housing is always aligned with the tongue anywhere along the stamping line of the press machine, and has a groove disposed thereon that aligns the jib base with the support member.

The invention will now be described in detail with reference to embodiments illustrated in the accompanying drawings.

A material checking device 18 for accurately locking the material 16 in a predetermined position above is interlocked with the material supply device 14.

The press working device is mounted on the bed 12 in a direction transverse to the press working line A-A.

However, in this drawing, only the progressive die 20, the press device 22 of the present invention, and the conventional sliding body 24 are shown to simplify the explanation.

The drive for all these accessories is provided by a drive shaft 26 mounted around the bed 12.

The timing of the operating sequence of all accessories is also obtained by rotating their drive shafts by suitable means, such as variable speed drive means or motors (not shown).

In FIG. 2, only the press device 22 and the drive shaft 26 according to the invention mounted on the manufacturing machine 10 are shown.

The drive shaft 26 is supported around the bed 12 at corner brackets 28 and is engaged with bevel gears 30 at each corner thereof.

Each corner bracket 28 is specifically configured to support a pair of orthogonally aligned shafts 26 in a single housing and is attached to machine 10 by bolts (not shown).

The press device 22 of the present invention applies a series of press operations to the material 16 using a pair of gang slide devices 32 across the press line A-A.

Each of the gang slide devices 32 includes a mask housing 34 to which a number of reciprocating slides are removably attached.

Each of these sliding bodies operates in a direction perpendicular to the press working line A-A, and is held by a jib base that restrains its movement about its axis at any relative angle to the mounting surface of the bed 12. .

However, for convenience of explanation, only the horizontal slider 36 that is mounted thereon moves in a direction parallel to the surface, and the vertical slider 38 that is mounted on it that moves in a direction perpendicular to the surface is shown.

An actuating device for individually driving these sliding bodies from the shaft is interlocked with each gang slide device 32 and is connected to the shaft 26.
It responds to the cam 40 attached to.

A standard holding device for securing the tool is included on all slides, but the slides are not shown here with tools for the sake of brevity.

When supplementary support means are required for shaft 26, the attachment extends from each mask housing 34 a support member shaped to suspend bed 12.

Each jib base and support member 42 is a mask housing.

On the pufferfish 34, the mounting of the increasing multiple has a mounting position that matches the pitch.

The gang slide assembly 32 is mounted to the machine 10 in a T-shaped slot 44 located above the bed 12 and parallel to the stamping line A-A.

Most simply, the mask housing 34 includes a mounting plate 60 shaped with a tongue 46 and a groove 58 in overlapping relationship on opposite sides of the same axis.

Each support member 42 includes means on the suspended portion thereof for engaging a bearing cap 62 surrounding the shaft 26.

These means are of arcuate shape which can be arranged to fit around the bearing 64 on the shaft 26;
It includes a threaded hole (not shown) for securing a bearing cap 62.

The same arcuate shape is also provided on the cap 62 which is fixed to the support member 42 with a bolt 66 passing therethrough.

Each support member 42 is attachable to the mask housing 34 at a mutually interchangeable attachment location and occupies one of the attachment locations along the longitudinal axis of the tongue 46. There is.

This pitch distance "X" is equal to the minimum thickness of the support member 42 in the direction of the tongue.

The thickness of support member 42 can vary by a multiple of distance "X" depending on the magnitude of the load transmitted from shaft 26.

The installation status is mutually compatible, the installation position is the distance “X”
Attachment is obtained by placing the holes 68 through the increased distances mentioned above.

Since the increased distance is a multiple, multiple mounting holes 68 are spaced apart from each other by a distance ``X''.

A key 70 shaped to engage groove 58 aligns support member 42 with respect to shaft 26 .

Bolts 50 are mounted through holes 68, such that the number of bolts 50 used to secure support member 42 to mask housing 34 is the number of thickness increments varied by a multiple of distance "X"'. be equivalent to.

Since the tongue portion 46 can be fitted along the entire length of the T-shaped slot 44, the mask housing 34 can be installed steplessly at any location along the press processing line A-A. It is.

The bed 12 receives the press load from the shaft 26 through the support member 42, and since the support member 42 has the ability to be attached interchangeably, it can be easily slid anywhere on the mask housing 34. can be fixed to.

Therefore, although the support members are shown attached at each end of the mask housing in the second and first degrees, a single support member is placed in close proximity to the slide that produces the maximum press load. It can also be used.

Each horizontal slide 36 is removably mounted on the mask housing 34 within the horizontal jib base 72 and is individually driven from an actuator as shown in FIG.

The slideway 74 is arranged on the horizontal jib base 72 and guides the horizontal slider 36, which is shaped to be movable in two directions.

A horizontal jib base 72 is attached to the mask housing 34 in an interchangeable mounting position and has a thickness equal to the pitch distance "X" in the direction of the tongue 46.

This thickness can vary depending on the tool used on the horizontal slide 36.

The horizontal jib base is compatible with each other by changing its thickness to provide an increment that is a multiple of the pitch distance "Xl+" and by placing a threaded hole (not shown) at a distance of the horizontal jib base's thickness increment. It is obtained by placing it in a penetrating manner.

Since the mounting is of varying pitch, increasing in multiples of the pitch distance "Xts," the multiple threaded gap holes 48 are separated from each other by a pitch distance tl X jl.

A key 82 having a shape capable of engaging with the groove 58 is disposed and thereby aligns the horizontal slider 36 with respect to the process line A-A.

Bolts 84 pass through gap holes 48 and secure horizontal jib base 72 onto mask housing 34.

Also, the number of bolts 84 in the installation is equal to the number of pitch increments.

A standard tool holding device is disposed integrally on the horizontal slider 36 at its tip, and attachment means such as a keyed bracket 86 having a hole 88 are provided.

The rear end of the slide 36 is also provided with suitable means, such as a shaped slot 92 pivotally connected to one end of a drive link 90 extending from the actuator.

The actuator on each horizontal slide 36 includes a lever 94 having a gum follower 96 rotatably mounted at one end and a pivot link 98 at the other end.

This lever 94 has a pivot link 98 and a cam follower 96.
The drive link 90 is pivotally connected to the other end of the drive link 90 between the two ends.

The pivot point 100 of this lever 96 connects the pivot link 98 to the horizontal jib base 72 using suitable means, such as a bolt 102 passing through a bearing plate 104 into a threaded hole 106 on the horizontal jib base 72. 72.

The adjustment means for changing the relative movement position of the horizontal sliding body 36 along the direction perpendicular to the press working line A-A is a stepless position variable adjustment means between the pivot link 98 and the horizontal jib base 72. By locking the link to the horizontal jib base by means of a locking key, it is possible to cooperate with the actuating device.

This means that the pivot link 98 has the key 108 and the slot 1
10 and fixing the threaded rod 112 thereto.

The slot 110 is longitudinally aligned with and extends through the key 108, while the threaded rod 112 is disposed along an axis parallel to the coincident axes of the slot 110 and the key 108.

On the horizontal jib base 72 is a partition wall 116 having a keyway 114 and a gap hole 118, the axis of which is aligned with the slideway 74.

Pivotal link 98 connects horizontal jib base 72 in a relationship that engages key 108 with keyway 114 and threads threaded rod 112 through gap hole 118 to position nuts 120 on either side of spacing 116 thereon. Fixed to.

As shown in FIG. 5, each vertical slide 38 is removably retained on the mask housing 34 within the vertical jib base 122 and is individually pivoted from an actuator.

The jib block 124 is secured to the vertical jib base by means such as bolts 126 and is connected to the jib key 1.
28 is arranged to guide a vertical slide 38 which includes a slideway 130 of complementary dimensions therewith.

To securely hold the vertical slide 38 around the jib key 128, for example, bolts 134 can be used to securely hold the vertical slide 38 around the jib block 12.
A jib cap 132 fixed to 4 is used.

Of course, the movement of the vertical slide 38 can be guided by appropriate configurations such as providing a slideway within the jib block 124 or configuring the vertical slide to move through the jib block. You can also do it.

Vertical jib base 122 is attached to mask housing 34 in an interchangeable mounting position and has a thickness along the longitudinal axis of tongue 46 equal to a distance "X91".

This thickness can vary depending on the tool used on the vertical slide 38.

Vertical jib base installation is compatible with each other in the condition “distance”
Attachment is obtained by repositioning and placing threaded holes (not shown) through the jib base at a distance of the increments of thickness, so as to provide stepwise increments that are multiples of X11.

Since the mounting pitch is changed to increase or decrease in this way, a large number of threaded holes have a pitch distance IT
They are separated from each other by 9+.

A key 136 shaped to engage groove 58 is arranged to align vertical slide 38 with stamping line A--A.

Bolts 138 pass through gap holes 48 and secure vertical jib base 122 onto mask housing 34.

Also, the number of bolts 138 is equal to the number of thickness increments multiplied by a multiple of the pitch distance "Xn."

The legs 140 above are separated.

Threaded holes 1 along the longitudinal axis of each leg 140
42, the threaded hole 142 has a standard tool holding arrangement for the vertical slide 38.

A bearing slot 144 is positioned through the center of the vertical slide 38 on the portion connecting the legs 140.

Each vertical slide 38 includes a pivot arm 146 having a cam follower 148 rotatably attached to one end and a finger link 150 secured by a bolt 151 to the other end.

Between the cam follower 148 and the finger link 150, the pivot arm 146 is pivoted to the vertical jib base 122 at a pivot point 152, for example by a pin 154.

The free end of finger link 150 is configured to engage a bearing slot 144 in vertical slide 38, and a roller 156 is rotatably mounted therein.

The pin 154 is placed elsewhere through both the pivot arm 146 and the vertical jib base 122 to provide a second pivot point 152', thus connecting the pivot point and the cam follower 148 and roller 156. You can change the distance ratio between the two.

The press device according to the present invention is configured to apply press working operations to the material 16 in accordance with various different press processes.

This press working is carried out by mounting the machine 10 on the bed 12 with a pair of mutually complementary gang-slide devices that work together in the direction transverse to the press working line A-A, as shown in FIG. achieved.

In certain press nib runs, each gang slide assembly 32 is connected to a horizontal slide 36 and/or a vertical slide 38.
and these two tank moving bodies are arranged so that they cooperate with the horizontal sliding body 36 and/or the vertical sliding body 38 of the other gang slide device 32 during execution of the desired pressing operation. be.

Each horizontal slide 36 cooperates with either the other horizontal slide 36 or vertical slide 38, or both.

Of course, this also applies to the vertical sliding body 38.

Since the work plan for press working is directly related to the parts to be made, there may be an infinite number of work plans depending on the number of press work steps and the order of the work.

Therefore, according to this press work plan, the mask and
Mounting of the slider at an interchangeable position on the housing 34 allows the mask housing 34 to be placed anywhere along the stamping line A-A in relation to the pitch increase or decrease and the standard tool holding device on the slider. Since the press device 22 of the present invention can be installed steplessly, it can be easily applied to any press working plan.

After this gang slide device 32 is configured in accordance with the intended press work plan, tools are fixed to the tool holding device of each sliding body.

This, of course, may be done before or after the gang slide device 32 is installed in a cooperating position on the bed 12.

Next, the sliding body is operated in a direction across the press working line A-A as shown in FIG.

In the figure, only the tool on the vertical sliding body 38 is shown by imaginary lines.

It should be noted that there are no restrictions on the tools used, so all normal press forming operations can be performed.

Reciprocating tool drive for each horizontal slide 36 is effected from the actuator by placing a cam follower 96 in the inner race on one of the cams 40.

When the shaft 26 is rotated by the cam 40, the cam follower 9

The stroke of the horizontal slide 36 is proportional to the rise of the cam 40, but the position in its direction of movement at which this stroke takes place can be varied by means of an adjusting device.

This can be done by simply loosening the bolt 102 and simultaneously rotating both nuts 120 in the same direction to lengthen or shorten the effective length of the threaded rod 112.

Of course, the movement speed of the horizontal sliding body on the moving stroke is determined by the cam 4.
