Description

The automatic cutting-remaval system of automobile wheel casting

The present invention relates to a new cutting removal system that can contribute to productivity and quality improvement by enabling a faster, more precise and automated continuous high efficiency cutting removal of the gate generated during automobile wheel casting molding.

Typically, automotive wheels made of aluminum or alloy are molded by a casting method (including castings and die castings) in which molten AL or alloy molten metal is filled at high pressure into a mold to produce a desired shape through rapid cooling.

In addition to the actual product shape, a plurality of gates or overflows are attached to the wheel castings taken out from the casting molds due to the characteristics of the casting method.

This gate or overflow is an essential part of the casting process, but after the casting is completed, it is unnecessary and needs to be quickly and neatly removed.

On the other hand, the gate that occurs during the casting of the wheel for the automobile, there are many differences depending on the casting method, the required casting quality, the manufacturer, etc. together with the shape, size, shape of the wheel,

According to the conventional practice of the technical field, the main gate, which is written as a main path through which a large amount of molten metal is injected, is formed in the upper part of the center of the wheel caster 100 for automobiles. (A) one is formed,

Several gates around the outer circumferential surface are used to inject molten metal auxiliaryly from the side, and are formed to have a constant thickness and length along the upper and lower lines of the outer circumferential surface, and are formed at about 2 to 5 locations around the entire circumference (B ) Is usually formed.

In the related industry, many efforts have been made to develop a rapid and precise removal device for the casting gate (main gate part, side gate) in response to the demand of automobile wheels which are increasing rapidly.

As a result, many companies have reported that a variety of automated continuous removal equipments are being developed and installed one after another.

However, it is clear that the gate elimination equipment of conventional automobile wheel castings, which has been distributed so far, has made a lot of leaps and progresses according to the general industrial development.

The complex work process, configuration, and system that have not been improved so far are still intact, so the effort and cost burden of the production and installation of the equipment is still a big problem.

In particular, there is a significant problem that has to limit the manufacturing cost reduction of automobile wheels, in contrast to the recent situation that the gate removal work takes a lot of time unnecessarily, cost-cutting efforts for each field is a long time,

In addition, when working with other wheel castings, which differ in shape, shape and size, the work conditions for each type must be tailored for each work.

The development of automated mass production system has a problem that acts as a significant detriment, which is urgently needed to improve.

Accordingly, the present invention has been devised to solve the above problems, and the identification of the type (size, shape, shape) of the wheel and the position of the gate, which is the object to be removed, and each part when removing the gate (main gate, side gate) of the automobile wheel. In addition to the automatic adjustment of processing conditions, it is possible to quickly and precisely respond to wheel castings by process.In particular, a plurality of main gates and circumferences of different shapes, sizes, and shapes are attached at different positions and along the wheel side line The technical goal is to provide a new gate removal system that can contribute to the productivity increase due to shortened working time by enabling the simultaneous and rapid circular cutting process of the entire side gate formed relatively long.

The present invention for achieving the above technical problem is a vision means 700 for determining the model of the wheel by obtaining an image of the wheel casting; The wheel measuring and positioning device 200 which moves the wheel casting whose model is identified by the vision means, reads the direction and position of the side gate in advance, and then rotates it in the required direction without interference, thereby accurately determining and fitting the position. Wow; The set wheel casting is precisely and firmly clamped by a multi-directional high efficiency triaxial clamping pin, and then simultaneously cuts and removes the main gate and a plurality of side gates simultaneously using a main gate removal tool and a side gate removal tool. Device 300; Outlet side air cleaning device 400 for injecting air into the cast-wheel removed gate to remove the chips, dust and other foreign matter present in the wheel: and includes an outlet side air cleaning device from the wheel processing setting device One side of the section is to effectively pick up the wheel castings by connecting the wheel casting transport apparatus 500 corresponding to each process.

As described above, the gate automatic cut removal system of the automobile wheel casting of the present invention grasps the type of the wheel casting and the direction of the sidegate during the removal operation of the gate (main gate, side gate) formed in the automobile wheel casting. Next, not only the processing conditions suitable for the shape are automatically set, but also fastening and effective use of the wheel castings can be fixed.In particular, the main gate formed at the center of the wheel and the side gates formed at the outer circumference are cut at the same time. As it can be removed, it is a useful invention that greatly contributes to the reduction of working time and productivity, as well as to the convenience and the improvement of the working quality due to the precise and stable cutting conditions.
