Description

Foreign material removal device of press bolster rail {A DEVICE FOR REMOVING POLLUTANT FROM PRESS BOLSTER RAIL}

The present invention relates to a debris removal device of a press bolster rail, and more particularly, to install a rubber member in contact with the rail in front of the running direction of the trolley, so that the rubber member is in contact with the rail by a spring member at a constant pressure To adjust the installation length of the rubber member to compensate for the worn length of the rubber member, to prevent foreign cleaning and to extend the service life of the rubber member. Relates to a device.

In general, automobiles are provided with various panels. The panel is molded by stamping a steel plate using a mold in an automobile manufacturing plant. The mold is formed of an upper mold and a lower mold, and a front end portion for shearing the panel is formed at portions where the upper mold and the lower mold contact each other in order to mold the panel into a desired shape. In addition, the mold is provided as a weight in order to easily process the external appearance of the panel.

The mold is installed in a press located in one place to form a panel. In addition, since the mold requires different molds by changing the shape and work schedule of the panel to be molded, the movement of the mold is frequently performed between the press and the mold storage station which are fixed at a predetermined position.

Therefore, in the related art, the mold is transferred to a mold storage station by using a cart or a wheeled carriage to move the mold, but a safety accident occurs in which the mold is damaged or the foot is injured by dropping the mold during the transportation process.

Accordingly, a rail was installed between the press and the mold storage station, and a bolster on which the mold was raised was installed on a trolley provided to move along the rail, so that the mold was moved to a desired predetermined position using the rail. Here, when the trolley moves, foreign matters in chips or dust generated in the press workshop are accumulated off the rails, and the trolley is unbalanced with the rails by the foreign matters, and thus the rollover is stopped or stopped. Therefore, a method of removing foreign matters has been proposed by installing a foreign matter removal rubber in contact with the rail in front of the vehicle traveling direction.

However, since the rubber is simply attached to the trolley, when the wear occurs due to friction with the rail, a gap is formed between the rail and the rubber, thereby deteriorating a foreign material removal function.

The present invention has been made to solve the problems described above, can be installed so as to adjust the length of the rubber installed in front of the truck running the rail can extend the service life of the rubber, the rubber and It is an object of the present invention to provide a foreign material removal device of a press bolster rail configured to be in contact with a constant pressure to prevent cleaning failure due to poor contact between rubber and rail.

The foreign material removing apparatus of the press bolster rail of the present invention for achieving the above object is installed in a trolley for mounting a mold to run the rail, the foreign material removing apparatus for removing the foreign matter of the rail, in front of the traveling direction of the trolley An upper body installed and having a through portion formed therein; a pressure plate installed in the upper body and receiving pressure in an outward direction of the body by a spring member installed inside the body, and a pressure plate having a protrusion formed in the through portion direction; A lower body inserted into a through portion of the upper body and coupled to a protrusion of the pressure plate; And a rubber member having one side coupled to the lower body and the other side contacting the rail.

In the present invention, the upper body,

The main body is coupled to the balance, characterized in that it is provided with a sub-body screwed to the main body.

In the present invention, the lower body,

It is characterized in that the coupling hole formed with a screw portion is provided to be screwed to the protrusion of the pressure plate to adjust the length between the pressure plate and the lower body.

In the present invention, the upper body is characterized in that the air hole for inflow and outflow of external air is provided.

Hereinafter, a foreign material removing apparatus of a press bolster rail according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view schematically showing a combination of a debris removal device and a trolley of a press bolster rail according to a preferred embodiment of the present invention, Figure 2 is a debris removal device of a press bolster rail according to a preferred embodiment of the present invention Side cross section view.

As shown in Figure 1 and 2, the foreign material removing apparatus 100 of the press bolster rail according to the present invention, the upper body 10 is installed on the trolley 11, and is installed inside the upper body 10 The pressure plate 20, the lower body 30 coupled to the lower portion of the pressure plate 20, and the rubber member 40 coupled to the lower body 30 are provided.

The upper body 10 is installed in front of the cart 11 running direction. The trolley | bogie 11 means the vehicle for moving the metal mold | die which forms a motor vehicle panel to a predetermined position using the rail 13.
