The present invention will be described below with reference to the drawings.

The present invention contemplates the pressing of sheet material between mold members and also the advancement of such sheet material so that it can be shaped and compressed therebetween.

In one form of the invention shown in FIG.

There, the sheet is passed between roll formers so that a predetermined cross-sectional shape or structure is formed.

A gripping and feeding mechanism 4 is provided, which comprises a gripping and feeding carrier 8 which is longitudinally movable on suitable rails towards and away from mold members 20, 21 (cited below). Equipped with:

This gripping and feeding carrier has one lower fixed gripping and feeding member 5 and 1.
comprising at least two gripping and feeding members 5 and 6 consisting of two upwardly movable or adjustable gripping and feeding members 6, the upper and lower surfaces of which are preferably formed at least initially by a roll forming device 2; Lulatan (Iuratl +

The upper gripping and feeding member 6 is vertically movable towards and away from the lower gripping and feeding member by hydraulic control.

+) A plurality of biasing means in the form of mitswitches are provided in cooperative relation with the gripping and feeding carrier and the gripping and feeding members 5, 6.

The limit switch means are the lower and upper gripping and feeding members 5.
6 and in cooperative relationship with the gripping and feeding carrier.

A control means, such as a hydraulic control means, is provided on the gripping feed carrier and/or
or coupled to one of the gripping and feeding members (5, 6) so that the gripping and feeding carrier and the gripping and feeding member (5, (Is) can be advanced longitudinally towards and away from the mold member 20.21 It looks like this.

A distance control switch is provided consisting of a rear control switch (A), a front control switch (13) and an intermediate control switch (C).

Spaced in front of the gripping and feeding member 5.6 is a mold member 20.
21 are provided and include an upper mold member 20 and a lower mold member 21.

Preferably, the lower mold member 21 is fixed and the upper mold side 20 is movable upwardly and downwardly relative to the lower fixed mold member 21. However, it is also possible for both mold parts to be movable.

The upper mold member 2D has one body portion 22 and one downwardly facing step 2D, and when sheet material is placed between said mold members 20, 21 and the upper mold member 20 moves downwardly relative to the lower mold member 21. The sheet material 1 is interlocked between them to form a step.

Preferably at least the body portion 22 and the upper mold member 200
The surface of the step 26 and the upper surface 24 of the second mold member 21 are suitably contoured to substantially conform to the desired shape, structure or cross-sectional shape of the sheet material.

If desired, a spring-loaded template extends downwardly from the lower surface of the body portion 22 of the mold member 200, the lower surface being given a suitable cross-sectional shape, the template extending slightly below the lower surface of the step 2. is biased away from the body portion so that the

In use, as the upper mold member 20 moves towards the lower mold member 21, the mold plate there contacts and grips and holds the sheet stock 1 while the step 26 moves downward to create a step in the material 1.

Upper and lower control switches (E,), (F) are provided in cooperative relationship with the upper mold member 20.

Hydraulic control means are provided in cooperation with the upper mold member 20 to permit vertical movement of the upper mold member 20 towards and away from the lower mold member 21.

A guillotine 40 is provided in front of the mold member, which preferably includes an upper fixed guillotine blade 41 and a lower movable guillotine blade 42 . However, if you wish, you can make both blades movable.

The gripping and feeding carriers 5 and 6, the mold members 20 and 21, the guillotine 40 and the control switch are preferably electrically controllable and connected to a central control means or panel, which control means or panel is arranged in a predetermined number. Programming is provided to determine the number of cross-sectional shapes to be formed into the sheet material 1 before the guillotine is operated to cut the sheet material containing the cross-sectional shape sections to a length.

The upper mold member 2,0 preferably has its main body portion 22 and/or
Alternatively, the length of the template is greater than the sum of the length of one tile face and the length of one step molded into one tile. In this way, the main body 22 or the template 6 connected thereto
o The sheet material 1 is formed into a suitable shape or structure, or one step of one tile section and one section of material shaped in cross-section is advanced to have one step formed. Complete or finish the molding of the shape and structure to a length sufficient to cover at least the two main body parts. The distortions, strains and stresses that occur in the metal material can be removed by methods well known and used in the forming process of sheet materials by previously profiling or completing the profile of such sections. I found out that it is possible.

Still referring to the drawings, the metal strip 1 is fed through the roll former 2 and then passed through the gripping and feeding members 5, 6, thereby advancing it to a position between the mold members 20.2M.

The upper gripping and feeding member 6 first moves towards the lower gripping and feeding member 57 and grips the sheet material therebetween.

- Upper and 1: Force switch control means (G) and (■
1) Q'l is provided in a cooperative relationship with the upper gripping and feeding section A6. A biasing member in the form of an arm 65 is provided on the upper gripping and feeding member 6 so that hydraulic pressure forces the gripping and feeding member 6 downwardly to force the material 1 onto the upper and lower feeding portions. When gripping the stand, the lower control switch (11) is energized and the central control means causes the horizontal hydraulic biasing means to move the clamping and feeding member 5.6 (between which the sheet material (hold it) and move it forward toward the mold member 20°21.

A distance switch is provided consisting of a front (A) and a rear (B) control switch, preferably the distance between the front and rear control switches, and thus the distance of the sheet material being advanced, is at least one tile surface length and molded. Hydraulic operating means or other advancement means are sufficient for the length of one step of the tile to be removed 5, the gripping and feeding member 5,
6 and the carrier is advanced longitudinally until the carrier or the detail arm extending from the lower gripping and feeding member 5 contacts the foremost control switch (I3). This biases the upper mold member 20, causing the upper blade mold member to move downward.
21 (Press and grip the sheet material 1.

Upper (E) and lower (F) control switches are provided in cooperative relationship with the upper mold member 20 so that the force mold member 20 moves downwardly and the material 1 is pressed between both mold members to form a step. When forming the sheet material 1, the upper mold member 20 or the biasing arm associated therewith contacts the lower control switch (F), which causes the upper gripping and feeding member 6 to move in the vertical direction and displacing the lower gripping and feeding member. Stay away from 5.

The upward movement of the upper gripping and feeding part B brings the detail arm 65 into contact with an upper control switch (G) which is provided in a position or in a cooperative relationship with the carrier or the upper gripping and feeding part A6. . When the upper control switch (G) is activated, the horizontal hydraulic piston is actuated to move the gripping and feeding members 5, 6 and the carrier into the carrier 8 or the gripping and feeding member 5.
, 6, one of the cooperating arms is the rear control switch (A)
1" downwardly and away from mold members 20, 21 until biased.

Upon contact with the rear control switch (A), the upper gripper 6 moves towards the lower feeder 5 and grips the sheet material 1 between the two.

After that, the gripping and feeding member 6 is switched to the lower control switch (■1
), thereby preventing the upper mold member (20) from moving downwardly away from the lower mold member (21).

The upper mold member 20 or the biasing arm connected thereto then contacts and details the two-way control switch (E) cooperating therewith. As a result, the horizontal piston attached to the gripping and feeding companion 8 or the gripping and feeding parts 5, 6 moves the gripping and feeding parts 5, 6 or the carrier 8 in the longitudinal direction to the mold parts t, J'2.
Advance toward 0.21. The material thus molded and stepped is advanced from the mold parts 20, 21, and a predetermined length of material 1 is further placed between the mold parts 20, 21.

Preferably the central control means is electronically or electrically operated and programmable to control the number of cross-sections required. Furthermore, the control switch is connected to and operates via electrical or electronic central control means.

Following the above procedure, the same procedure is continued until the required number of cross-sections have been molded. When the last cross-section has been molded, the central control means is brought into close proximity to the rear of the forward control switch (B). Activate the intermediate control switch (C).

In this way, in order to mold the cross-sectional shape or mold a step in the last required section of the finishing material 1, the upper mold member 2° is moved to the lower mold member 2.
1, the lower control switch (F) is energized (as programmed in the central control) to move the upper gripping and feeding member 6 away from the lower gripping and feeding member 5. This causes the upper control switch (G) on the one hand to cause the hydraulic piston to move the gripping and feeding members 5, 6 downwardly away from the mold part U20.21.

However, the central means energizes the intermediate control switch (C) such that the gripping feed carrier 8 or one of the gripping and feeding members 5, 6 contacts (or the biasing arm contacts) the intermediate control switch (C). , the gripping and feeding section side 5.6 is closed, and the upper gripping and feeding member 6 is connected to the upper and lower gripping and feeding members 5.61''.
) is moved downwards to grip the material 1 between them.

However, as will be appreciated, the gripping and feeding carrier 8 and the member return a shorter distance than usual. Thus, once they close and energize the control switch, upper mold member 20 separates from lower mold member 21 while energizing the control switch so that material is hydraulically advanced between the mold members.

The length of the section 50 of material thus advanced between the mold members is substantially shorter than normal. Intermediate control switch (C
), the central control again enables movement of the gripping and feeding members and the molding member to form another predetermined number of profiled sections of full length.

Following the locking of the mold 20, 21 around the periphery of the shortened section, the gripping and feeding members 5, 6 are separated and moved rearwardly under hydraulic control.

When the gripping and feeding member 5.6 returns to the rear control switch (A), a further length of material 1 is advanced between the molds 20, 21 and at the same time the shortened length 50 of the material is connected to the guillotine member 41. The processing cycle is completed by being located between 42 and 42.

Guillotine 40 can be activated manually or automatically.

In one form of the invention, the activation by the lower control switch (F) of the guillotine to cut a foreshortened section of material is effected upon movement of the upper mold member 20 towards the lower mold member 21. The central control means is programmed as follows.

The guillotine is provided with a suitable control switch so that when the guillotine returns to its open position, the gripping and feeding members 5, 6 are opened;
Then return horizontally and lengthwise to their initial position. There, these parts again grip the material 1 and feed it forward between the mold parts 20,21.

It should be understood 7 that the short section 50 in the material 1 ensures that the guillotine does not cut through the entire length of the cross-sectional shape. If the entire length is cut off, material will be wasted.

By cutting or guillotining the shortening section 50 of the material 1, the elongation of the front end of the sheet material having a predetermined number of cross-sectional shapes can be reduced, and the overpart ring (
sharp cutting surfaces) can be achieved. This aids in sheet loading and sheet-to-sheet engagement.

It should be noted that during operation of the device, the sheet material 1 is gripped either by the gripping/feeding part 5.6 or by the mold part 20.21. The material is never allowed to loosen within the device. If this loosening were to occur, it would cause deformations and movements that would probably lead to deformation of the material, as well as reduce efficiency of operation.

The present invention also provides efficient operation for feeding, shaping, and forming sheet material into profiled sheet materials.
