Description

DESCRIPTION

PORTABLE PROFILE FOR PROFILE TRAINING

FIELD OF INVENTION

The present invention relates to the field of cold profiling. The invention generally relates to portable non-structural profiling machines for construction, such as wall trim or the like, gutters, concealed or rain gutters, gutters and profiles.

TECHNICAL STATE

Traditionally, gutter and trim profiles are produced by the methods known for band cutting and bending. The length of these profiles is limited to the size of the machines used which, in the most favorable case, do not exceed nine meters in length. This requires, in certain cases, to add and graft the profile / rail segments at the time of assembly. Furthermore, due to their large size and weight, these machines are not transportable to the jobsite for in situ profile fabrication.

Portable roll forming machines that continuously produce profiles and rails are currently known and commercially available.

These continuous portable roll forming machines have the disadvantage that in most cases they produce only one type of profile or rails, which is an important limitation. In known adjustable portable roll forming machines adjusting the forming stations to produce a different profile is time consuming, it requires opening the forming machine for individual adjustment and adjustment of the forming stations, and even replacing the forming roller sets according to the width. desired profile, which can only be effectively performed by specialized personnel, who do not normally perform or monitor the profiling of bands at the job site. Thus, the optimization of the process of changing the profile to be produced in these adjustable roll forming machines is extremely difficult, requiring thinning, testing and correction, with the consequent waste of material and time spent on site. In addition, such portable machines are difficult to design and regulation is complex, time consuming and arduous to perform on site. In addition, the usual minimum length of roll forming machines on the market is 3.5 meters, which requires a vehicle of considerable size to be transported to the site. In another aspect, the traction systems provided in these forming machines associated with forming stations have the disadvantage of making the operation of the forming machine more difficult.

The known rollers and multi-filers also have the drawback of appreciable band waste when changing the profile. This waste associated with known machines is important since aluminum, steel, copper or zinc bands are expensive and constitute a major factor in product profitability.

In another aspect, in known roll forming machines the end band profiling presents the problem of loss of tensile strength as the last forming band length advances within the machine forcing a manual final extraction.

Portable roll forming machines are intended to be operated by installers, who are knowledgeable only to operate such roll forming machines in a simplified manner. Therefore, personnel who specialize in the installation of the profiles that also operate the portable roll forming machines are not specialized in roll forming machines and are not prepared to perform the adjustment and adjustment of the forming stations or even to replace them in the on-site profile changes.

Thus known adjustable portable roll forming machines have disadvantages and do not solve the above mentioned problems.

On the other hand, the erection of walls in modern buildings or structures is increasingly made using metal profiles, usually made from previously finished metal bands, usually painted by lacquer. However, the thickness variability of such walls raises problems with respect to standard dimensions and especially when profiling on site.

There is therefore a growing need for portable multi-profilers to adjust and adjust to a different profile, fast and executable by any installer, reducing material waste so that even small quantities of differently sized profiles can be produced with a single profiler. , on-site, quickly, virtually waste-free, by unskilled personnel maintaining quality and low cost.

The multi-profiler according to the present invention solves the mentioned problems, being that the alteration of the profile dimensions produced by the same band, or even with the band alteration, is done quickly in a few minutes. The multi-profiler according to the present invention allows the production of profiles of different sizes from the same band and the same set of forming roller stations by simultaneously adjusting the forming roller stations in a single adjustment operation.

In yet another aspect, the inventive multi-profiler reduces the waste inherent in a profile change, which is virtually eliminated by reducing it to a little 3 to 4 mm in profile width, since the adjustment is made simultaneously in all the training stations and allows the continuation of the operation practically continuously and with minimum band wastage.

The forming machine according to the present invention has great versatility, optimization of the manufacturing process and significant improvements in operation.

It is an object of the present invention to provide a roll forming machine which allows the width of the roll forming produced to be varied without opening the roll forming machine and without replacing the forming stations, quickly, practically without waste and without the need for specialized personnel. This is achieved by means of synchronous adjustment of all forming stations, using an actuator, such as a simple crank, which can optionally trigger simultaneous adjustment of the guillotine shearing device. To this end, it is a further object of the present invention to provide a forming roller system independent of the traction system to ensure lower forming roller pressure and greater uniformity of the final product.

It is a further object of the present invention to provide a smaller and compact portable multi-profiler for easy transport and operation for on-site production of profiles or rails. Such an objective is achieved through the multi-filer preforming and feeding station of the present invention.

Another object of the present invention is to provide guillotine shearing means which are simultaneously adjusted by the synchronous adjustment system of the forming stations and allow for fast, safe and material free shearing.

The present invention further aims to provide a high longitudinal frieze forming station after passage of the profile through the cutting means.

It is an object of the present invention to provide profiles and rails with varying profiles and dimensions on the job site by the same portable roll forming machine, quickly and easily adjustable by unskilled personnel, in particular a profile with a high longitudinal strip.
