Description

Press automatic mold for the manufacture of cable tray sleeves

The present invention relates to a mold for manufacturing the front and rear walls of a cable tray sleeve. It is a press-automated mold, and when iron plate materials of various height dimensions are supplied by an automatic feeder (NC Feeder MC) of raw material coils, before and after the tray sleeve by forming and cutting It relates to a press mold that mass-produces noodles.

In general, recent buildings are becoming taller day by day in response to the needs of consumers as well as due to the development of building technology.

When a typical collective building such as an apartment building is constructed, not only electric cables for power supply, but also various electric cables such as communication cables and internet cables are disposed in each household.

Therefore, it is stipulated to secure a separate space for installing electrical and communication cables in the collective building in accordance with the relevant laws and regulations.

Accordingly, a cable tray is installed between the floors of the collective building to facilitate the installation of wires and cables for each household.

The size of the cable tray box requires the need for sleeve specifications of various sizes according to the height and use of the building.

(ex: based on sleeve height 170,180,200,210,220,230,250mm, etc.)

Therefore, when manufacturing the sleeve body, it was processed with a laser cutter and assembled and sold the tray sleeve. However, as the demand for the tray sleeve of the present invention increases as the number of layers increases day by day, it was manufactured by laser cutting and bending with a bending machine. Due to the failure to comply with the delivery deadline, conflicts with the supplier occurred, and production with press molds was reviewed, but in order to reduce the burden of developing molds of various specifications, production of various standard products with a single automated mold is required.

And the tray rail is mounted on the side of the cable tray and is vertically connected to the upper layer or the lower layer.

In addition, in the conventional cable tray of the penetration type or member connection type, there is a risk that concrete mortar flows into the upper opening during the construction process, and workers in various fields must install a protective cover to prevent the opening from falling during work or movement.

In such a conventional cable tray, one of a through-type and a member-connected type must be selected according to a construction site, so there is an inconvenience of having to fix the safety cover and the tray.

In order to solve this problem, the prior patent includes a body in which a hollow interior is formed with a width corresponding to the width of the rail; at least one locking portion provided on both side walls of the main body to adjust at least one unfolding length; And the upper and lower parts of the main body are respectively hinged in a state of being divided into two sides, folded by individual rotation, and a plurality of long holes parallel to the surface are formed.

However, the prior patent has a problem in that when a worker who constructs the upper folding part steps on it, the folded part is inserted into the main body, the operator's foot falls off, and the worker's foot can become a monche.

In addition, when the rail is coupled, since it must always be coupled from the inside, the assembly is inconvenient, and there is a problem in that there is no configuration for installing a grounding wire.

In addition, as the iron plate having a flat plate shape without any shape is used, there is a problem in that durability is weak.

Accordingly, there is a need to develop an automatic press mold capable of manufacturing various standard products by solving the problems of these existing products.
