Description

A Moulder of Inside Pot of A Electric Cooker

The present invention relates to a chamfering machine for finishing the circumference of the upper end of the inner pot of the electric pressure cooker, in detail the electric pressure cooker has a concave-convex shape around the top of the inner pot for the locking and opening function of the rice cooker lid and the inner pot, Since the edges of the inner circumference of the inner pot cannot be uniformly finished, a weight balance weight and an angle balance weight are attached to the chamfering tool so as to be processed while applying a constant force according to the uneven shape. The present invention relates to an inner pot chamfering machine of an electric pressure cooker capable of efficiently processing a corner portion efficiently in a short time.

Inner pot of the electric pressure cooker is a nature of the pressure vessel, as shown in Figure 2, 6 wings 10 and six inner grooves around the upper end of the inner pot to exhibit the locking and opening function with the rice cooker lid The convex-concave shape which consists of (20) is made.

By the way, if the upper circumference of the inner pot is in the shape of a circle, that is, the wing shape is not formed in the inner pot when trimming the upper circumference of the inner pot after the first and second draw ring (inner pot production), The edge of the inner circumference of the inner pot, which looks like a blade, can be easily chamfered from the shelf, but as of the present, the inner grooves of six places could not be processed in the state of the inner shape of the inner pot.

In order to solve the above problem of lathe machining, a press method for pressing a corner part that looks like a knife blade is forged. However, after pressing, a burr is generated in the corner part, so that the press method is not applicable in actual work sites. I wasn't.

Therefore, in the past, the iron brush was attached to the grinder to remove only the burrs of the corners of the inner circumference of the inner pot by hand. Of course, there was a problem in that the shape of the product is not uniform inferiority.

In addition, another method of the prior art uses a method of pushing the burrs of the corners manually by hand with a rope, but this also has a lot of defects due to poor workability and uneven quality due to manual work. .

The conventional method described above was possible as a commodity, but the non-uniform surface caused by hand was supplemented with post-coating, but since the post-coating also requires uniform coating of the coating liquid for uniform coating thickness, the inner pot The pretreatment should be thorough, and the heat treatment should be uniform even after application, because the coating solution should be sprayed in consideration of the flow of the coating liquid down deep inside the surface of the inner pot. .

The present invention has been made in order to solve the conventional problems in finishing the corners of the upper circumference of the electric pressure cooker inner pot as described above, for the elimination of defects caused by post-coating the inner pot first, fully automated After coating the aluminum plate in the state with the coating plate itself with superior quality, drawing (manufacturing the inner pot), and uniform the circumference of six irregularities (wings and grooves) without damaging the flange part of the coated inner pot. It was invented for processing.

In other words, it should be processed uniformly according to the uneven shape of the inner circumference of the inner pot, but conventionally, it was difficult to process uniformly according to the wing surface and the groove surface according to the uneven surface. This is because uneven processing results are inevitable depending on the processing speed.

Therefore, the most important problem is that the uneven parts must be uniformly processed. In order to solve this problem, an angle balance weight capable of absorbing the tool angle of the chamfering tool, which is sensitively changed by the uneven shape, can be absorbed. The weight balance of the chamfering tool is important in order to install it together, and to make the machining uniform evenly by riding freely along the wing, side, and groove side, so that the processing is uniform. Its purpose is to provide a chamfering machine to be uniformly processed to a certain amount of the corners around the top of the inner pot while balancing the angle and weight by installing the.

In order to achieve the object as described above, the present invention, the inner pot fixing base for mounting and rotating the inner pot and the inner pot fixing plate coupled to the inner pot fixing shaft for fixing the inner pot, the upper portion of the cooker wing, side, groove surface When the chamfering device moves up and down according to the uneven shape (that is, when there is an angle change), the angle balance weight that can absorb the change of the tool angle so as not to change the machining according to the angle change, and the chamfering tool Weighing along the side, side and groove surface to adjust the machining depth uniformly (i.e. to adjust the machining depth even if the tool blade touches, change, angle change or any other change) Chamfering device, characterized in that mounted on the device.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the chamfering machine according to the present invention.

1 is a perspective view of the inner pot chamfer of the electric pressure cooker according to the present invention, as shown,

An inner pot fixing pedestal 2 that is coupled to the motor (not shown) and rotates in a state where the inner pot 1 is mounted;

The inner pot fixing plate 5 which is coupled to the lower end of the inner pot fixing shaft 4 which is operated up and down by the hydraulic cylinder 3 at the upper portion of the inner pot fixing pedestal 2 and presses the inner lower part of the inner pot 1 to fix the inner pot 5. )and;

The inner pot fixing bracket (2) is installed on the work die (8), which is made of a chamfering device (6) for processing the edge of the inner circumference of the inner pot top is installed on the work die (8), the chamfering device (6) Is

An chamfering tool 6c having an end mill 6a mounted on one side thereof and having upper and lower ends fixed thereto by tool holders 6b and 6b ';

A weight balance weight 6d placed on and fixed to the chamfering tool 6c;

The tool holder 6b on the upper surface of the chamfering tool 6c is coupled to the pedestal 6e and the tool holder 6b 'on the lower side is engaged with the rotation shaft 6g in which the rotary disc 6f is inserted at one side, and the predetermined angle is fixed. A chamfering tool rotating device 6h for rotating;

It is characterized in that it consists of an angle balance weight (6k) is connected to the outer peripheral surface of the rotary disk (6f) and suspended on the wire (6j) hanging on the wire hanger (6i) of the upper rear.

Therefore, the operating state of processing the corner portion around the inner pot top is made as follows.

The inner pot is mounted on the inner pot fixing bracket so that it is fixed not to move by the inner pot fixing plate. Then, the inner pot fixing bracket starts to rotate, while the end mill mounted on the chamfering tool of the chamfering device touches the edge of the upper circumference of the inner pot. Start processing.

At this time, when the end mill rides the corner and meets the wing, the tool angle changes, but the tool angle naturally changes by the angle balance weight installed together with the chamfering tool (that is, by the weight of the angle balance weight at the rear). As the chamfering tool is lifted slightly, it is processed without damage to the wing. In addition, each balance addition absorbs residual vibrations such as shaking due to high-speed rotation of the tool during chamfering, thereby processing a smooth processing surface.

Next, when the wing portion is finished and returned to its original state, the chamfering tool naturally descends due to the weight of the weight balance weight placed on the upper part of the chamfering tool, and as a whole, it can be processed with a constant force by the weight balance weight. To make it possible.

According to the inner pot chamfering machine of the present invention made of the above object and configuration, it is possible to uniformly process the corner portion around the top of the inner pot uniformly to a certain depth without damaging the coated portion due to the angle balance weight and weight balance weight installed with the chamfering tool. Can be made automatically, so productivity is improved, and the defective rate is remarkably reduced.
