Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to home electric appliances and mobile phones.
Machine with profiled moldings such as machining having a curved surface or curve such as the outer peripheral for deburring device moldings for use in finishing to cut the periphery, in particular differ in the left and right side shape
Also, the present invention relates to a deburring apparatus for an outer periphery of a molded product for cutting and finishing a molded burr on an outer peripheral portion of a thin magnesium molded product . 2. Description of the Related Art Conventionally, in the case of performing peripheral finishing of a molded article having a deformed and curved surface or a curved line, a rotating blade such as a molding burr or a gate, a grinder or an end mill, or a nipper or a bow saw is used. The process of removing to some extent with a cutting tool and finishing it by hand using a file, sandpaper, or the like was a common deburring process. However, the manual deburring process is very inefficient, has poor dimensional accuracy, and produces many defective products, so that stable production cannot be performed and profitability is not good.
Also, at this time, dust was generated, so that the working environment was poor. Further, when performing an outer peripheral finishing of a molded product having a deformed shape, a curved surface, a curved line, and a thin wall, the molded product is liable to bend, warp, or crack or crack during processing. Had to do the work. Especially when removing the gate, it can not be removed at a stretch,
Since it had to be removed little by little, it was troublesome and workability was poor. In addition, if the amount to be removed is too large, when removing using a rotary blade such as an end mill, blurring and chattering may occur, resulting in deterioration of the finished surface accuracy, and escape or chipping of the material surface of the work may occur. However, the dimensional accuracy was unstable, and the product yield was poor because the product was liable to become defective. For this reason, a deburring apparatus for the outer periphery which automatically cuts and finishes the outer periphery of the molded product by machining is devised. As this device, a milling machine or an NC machine tool equipped with a copying device is used, and an end mill or the like is attached in advance and set at a predetermined position, and the end mill moves along the copying sample or an end mill or the like based on a program. Deburring was performed while moving. [0005] However, when a deburring process is performed by attaching a rotary blade such as an end mill to the outer peripheral deburring device, a thin molded product of non-ferrous metal or a synthetic resin or rubber can be obtained. The molded product had a low strength of the material itself, and when the rotating blade was brought into contact with the material surface, the rotating blade was liable to be entangled or seized. Also, when using a rotating tool such as an end mill, vibration and noise were generated due to the rotation of the motor. Further, when a thin-walled molded product is cut with a rotary blade, the material surface of the work escapes or is chipped, so that defective products are easily produced. In addition, when using an NC machine tool, the equipment and maintenance costs are high, skilled programmers must be hired, and it is difficult for micro enterprises to purchase the NC machine tool. is there. On the other hand, when deburring an outer periphery of a magnesium die-cast product in a non-ferrous metal, if powdery chips such as a grinder are precipitated, magnesium chips are ignited or an end mill or the like is used. If the amount of cutting is small even with a rotary blade, the magnesium chips tend to ignite, and the surrounding oil may ignite and cause a fire. The cutting conditions are extremely difficult and the mass production It was difficult to ensure safety in the processing. For this reason, the outer peripheral deburring of the magnesium die-cast product is not performed by machining, and is currently performed by hand. According to the present invention, deburring is performed by machining to improve dimensional accuracy, which is most suitable for mass production deburring, can be performed without causing distortion in the work, and the replacement period of the blade is extended, thereby reducing the processing cost. it is possible to reduce the
High precision, especially in the outer finishing of magnesium products
Can be performed safely and machined to enable cutting deburring work
And to provide a molded article periphery for deburring apparatus as a capability. [0008] The present invention has been made to solve the above problems, that is, the center of the base.
And a work mounting table formed in accordance with the shape of the inside of the work is fixed, and a forming cam serving as a reference for the outer peripheral finish dimension of the work is fixed to both lower sides of the work mounting base, and the contact cam is brought into contact with the forming cam.

First, the work (W) is placed on the work mounting table (2), and the clamp (92) shown in FIG. 1 is actuated, and the pressing member (91) presses and fixes substantially the entire upper surface of the work (W) ( (See FIG. 2). Then, the left and right pressing cylinders (61) start the extension operation, the tool post (5) moves toward the center, and the contact roller (4) comes into contact with the forming cam (3) [FIG. )reference]. Next, when the extension cylinder is started by operating the moving cylinder (71) of the back and forth moving means (7), the cutting tool (8) is brought into contact with the contact roller (4).
The cutting position is determined via. The cutting tool (8) bites into the outer periphery of the work (W) by about 0.5 mm, and the contact roller (4) contacts the outer periphery of the forming cam (3) with a constant pressing force and rotates while rotating as shown by the arrow in the figure. The tool (8) follows the outer periphery of the forming cam (3) while the tool rest (5) moves left and right and back and forth. Then work (W)
Is cut by a cutting tool (8) as the moving cylinder (71) extends. FIG. 3 (b) shows the position where the outer periphery of the forming cam (3) is most protruded, so that the left and right pressing cylinders (6
In 1), this point is in the state of being most shrunk during processing. Further, since the right and left pressing cylinders (61) perform different expansion and contraction operations on the right and left sides, even if the work (W) has the shape shown in FIG. That is, a left-right symmetric curve as shown in FIGS.
4 (b) to 4 (e), parallel straight lines like the upper and lower sides in FIGS. 4 (b) to 4 (e), left and right linear shapes as in FIGS. 4 (b) and 4 (e), and FIG. ) Like byte (8)
It is possible to process even a curve with a vertical drop at the blade width. In particular, in the case of cutting a shape having many notches as shown in FIG. 4 (e), it is easy to lose when machining with an end mill, but a relief portion is provided so as not to lose the shape of the forming cam (3). Therefore, even with the above-mentioned shape, the outer periphery can be machined into a clean and predetermined size. When the contact roller (4) reaches the end of the forming cam (3) in this way, the pressing cylinder
When the contact roller (4) moves away from the forming cam (3) and the contact roller (4) moves away from the forming cam (3), the cutting tool (8) starts to work.
(W), the pressing cylinder (61) is in a contracted state. And a cylinder for moving the back and forth moving means (7)
When (71) is contracted, the tool rest (5) is returned to the original position as shown by the arrow in the figure [see FIG. 3 (c)].
When cutting the work (W), the cutting tool (8) cuts into the outer periphery of the work (W) by about 0.5 mm to generate cutting chips. Lost. Thereafter, the work (W) is detached from the work mounting table (2), the next work (W) is mounted, and cutting may be performed in the same manner as described above. At this time, the other half of the outer periphery of the work (W) may be finished using the apparatus of the present invention set separately or the apparatus proposed by the present inventors. When deburring a molded product such as a soft synthetic resin or rubber, the work (W) may be processed by attaching a blade (8) thinner than a cutting tool. Next, when a molded product having curves and irregular curves as shown in FIGS. 4A to 4D was machined using the outer peripheral deburring device of the present invention, defective products were generated. Deburring could be performed without any defects and with high efficiency. Further, when a thin molded product was processed by the apparatus of the present invention, there was almost no escape or chipping of the material surface of the work (W) generated when the rotary blade was used. Moreover, since no NC machine tools are required, there is no need for equipment and maintenance costs, and there is no need for skilled workers, and the work is simple and can be easily purchased even by micro enterprises. became. In addition, even when a material having a shape with many notches as shown in FIG. 4E was cut, there was no defective portion as in the prior art, and the outer periphery could be machined to a clean and accurate finish size. Further, conventionally, it has been difficult to remove the outer periphery of a magnesium die-cast product by a machine, but by using a non-rotating cutting tool as a cutting tool (8), heat is extremely generated unlike a rotating blade. There is little possibility that magnesium chips are ignited and the surrounding oil etc. is ignited and there is almost no risk of fire, and the peripheral finishing of magnesium die cast products can be done easily with mechanical equipment, and mass production deburring is possible It became. For this reason, the dimensional accuracy of 0.05 mm can be ensured, the processing time can be shortened, and the processing cost can be reduced. FIG.
In the case of deburring a magnesium die-cast product of a lid used in a mobile phone as shown in (f), when an end mill is attached to an NC machine tool and processed, the molded product is 100 on average.
At the time of the end milling, the end mill was broken, broken or cut poorly, and the end mill had to be replaced. On the other hand, in the processing method using the cutting tool according to the present invention using the cutting tool (8), it was confirmed that even if 10,000 molded products were processed, there was no abnormality and the processing could be continued. Therefore, the working cost can be reduced by extending the life of the blade (8) extremely. In addition, when deburring was performed using the apparatus of the present invention, finishing was conventionally performed by 15 people, and the same amount of work could be performed by 2 to 3 people, and no defective products were produced. According to the present invention having the above-described structure, the following effects can be obtained. According to the first aspect, at the center of the base (1) and
A work mount (2) formed according to the inner shape of the work (W) is fixed, and the work (W) is provided on both lower sides thereof.
A contact roller (4) for fixing a forming cam (3), which is a reference for the outer peripheral finishing dimension of the fixing cam, and bringing the forming cam (3) into contact therewith.
A tool post (5) that moves left and right and back and forth while being attached to the lower end, and is arranged at least on both sides of the work mounting table (2), so that the copying sample is placed at another conventional position. In contrast, since the forming cam (3) is fixed to both sides of the work mount (2), the structure becomes compact, and if a commercially available blade or molded cutting tool is mounted on the tool post (5) and used, the conventional rotation is achieved. Since a tool and a spindle are not required, vibration and noise due to rotation of the motor are not generated, so that structural strength is not required and manufacturing cost is low. In addition, since the copying process is performed using the forming cam (3) and both side surfaces can be simultaneously processed, the processing time is shortened, and the contact roller (4) serves as a stopper, so that the cutting tool (8) is used.
And the blade (8) can be constantly pressed against the work (W) with a constant pressing force. For this reason, deburring can be performed by machining, and the dimensional accuracy is improved, and the workpiece (W) can be processed without distortion, so that even a molded product of a material having no strength has a stable dimension and a rough surface of a cut surface. The temperature is also remarkably stable, and it is ideal for mass production in which deburring can be easily performed without skill. Further, the replacement period of the blade (8) is extended, and the processing cost can be reduced. Further, since the shape of the forming cam (3) can be freely manufactured, it is possible to work even if the both sides are different in shape, and it is also possible to work one side only in a part of the way. The parallelism on both sides is high. In particular, the outer peripheral deburring of magnesium die cast products can be machined unlike conventional manual processes, so there are almost no defective products such as conventional dimensional accuracy defects and warpage, and the processing time is shortened. In addition, the processing cost can be reduced, and the peripheral finishing of magnesium die-cast products can be performed with high precision and safely. Also, a work holding means is provided near the work mount (2).
