Diamond array segment manufacturing device and diamond array segment manufacturing method using the same
[0001] The present invention relates to a diamond array segment manufacturing device and a diamond array segment manufacturing method using the same, and more particularly, to a diamond array segment manufacturing device and a diamond array segment manufacturing method using the same, which can improve reliability by improving the quality of the formed array segment, and which can facilitate forming the array segment and minimize the installation area.
[0002]
[0003] In general, a diamond tool is a tool used to cut or polish workpieces such as stone, brick, concrete, and asphalt, and is composed of a shank in the form of a circular plate forming the body, and a diamond segment attached to the outer periphery of the shank to form a cutter portion that acts as a bite for cutting the workpiece.
[0004]
[0005] At this time, the diamond segments are mostly attached to the shank through a welding process such as brazing welding or laser welding, and the diamond segments are manufactured by mixing diamond particles on a metal powder such as nickel or cobalt, molding them, and then sintering them.
[0006]
[0007] However, in the past, when manufacturing such diamond segments, diamond particles were transferred and supplied onto a diamond segment forming device using a vibrating feeder. However, in this case, it was difficult to supply them quantitatively due to segregation of diamond particles and metal powder, and uniform supply was difficult due to them being biased or clumped to one side, which caused differences in the manufacturing quality of the diamond segments. As a result, not only did product reliability decrease, but manufacturing was also cumbersome as it was manufactured through several processes, and there was a problem that productivity was reduced because it took up a lot of installation space of the device.
[0008]

[0079]
[0080] Hereinafter, the present invention will be described in more detail with reference to preferred embodiments thereof.
[0081]
[0082] A diamond array segment manufacturing device according to an embodiment of the present invention is a device for forming an array segment attached to a shank in order to manufacture a circular saw blade, and can supply and form diamonds according to a desired position and arrangement, and by performing each process using a diamond segment mold that rotates 360 degrees, it is easy to form the array segment, minimize the installation area of the manufacturing device, increase the production volume of the array segment, and improve the reliability of the product.
[0083]
[0084] Referring to FIGS. 1 and 2, a diamond array segment manufacturing device according to an embodiment of the present invention may be configured to include a multi-station (100), a rotary table (200), a filling unit (300), a compaction unit (600), a pressurized extraction unit (700), and an operation control unit (800).
[0085]
[0086] First, the multi-station (100) can be formed of multiple stations depending on the process, and each station can perform its own process.
[0087]
[0088] In the present invention, each station is fixed in position so that the rotary table (200) rotates and the diamond segment mold (230) described later is positioned at the corresponding position to perform the corresponding task, and the filling unit (300), compaction unit (600), and pressurized extraction unit (700) described above can be installed.
[0089]
[0090] The above multi-station (100) can have each station arranged in a circular plane corresponding to the rotating rotary table (200).
[0091]
[0092] Referring to FIG. 3, the multi-station (100) is composed of four stations, and each station can be arranged at 90-degree intervals.
[0093]
[0094] Here, each of the above stations is configured as a pressing and extraction station, a diamond array station, a preparation and compaction station, and a metal powder filling station, so that when the diamond segment mold (230) is positioned at the corresponding location, the station can perform the set task. Here, a description of the operation, including the detailed configuration installed at the corresponding station, will be described later.
[0095]
[0096] Meanwhile, the diamond array segment manufacturing device according to an embodiment of the present invention may be provided with a base frame (10) in which the filling unit (300), the compaction unit (600), the pressurized extraction unit (700), and the operation control unit (800) including the multi-station (100) are installed and can support each component, and the base frame (10) may be formed in a box shape as shown in the drawing to support each component from above and have a structure that can be stored therein.
[0097]
[0098] The above rotary table (200) is installed adjacent to the multi-station (100) and is formed to be able to rotate around a vertical axis according to a control signal of the operation control unit (800), and a diamond segment mold (230) may be provided on the outer periphery.
[0099]
[0100] The above rotary table (200) can rotate 360 degrees, so that the diamond segment mold (230) can be positioned at the corresponding station according to the rotation.
[0101]
[0102] The above rotary table (200) can have multiple fitting parts (210) formed on the outer periphery.
[0103]
[0104] Accordingly, the present invention can be configured to include a cartridge (220) coupled to the fitting portion (210) and having a plurality of diamond segment molds (230) formed therein.
[0105]
[0106] Here, the cartridge (220) and the diamond segment mold (230) can be separated from each other and detachably coupled.
[0107]
[0108] In the drawing, the cartridge (220) shows a case where four diamond segment molds (230) are formed for each, but this is only one embodiment and the number of diamond segment molds (230) can be formed in various ways depending on the number of processes and the arrangement of stations.
[0109]
[0110] Referring to Fig. 4, the diamond segment mold (230) has a forming hole (231) formed in a shape corresponding to the array segment shape, so that metal powder and diamonds can be filled and arranged inside. Here, the forming hole (231) can be formed to penetrate in the vertical direction, and an extraction part (720) can be arranged at the bottom, and a press rod of the compaction part (600) can be arranged at the top.
[0111]
[0112] Meanwhile, the upper surface of the diamond segment mold (230) may be configured to include a pair of guide pin holes (232) at a set position, and a guide pin (233) configured at the upper portion to correspond to the positions of the pair of guide pin holes (232) and inserted into the guide pin holes (232).
[0113]
[0114] By adjusting the setting position between the multi-station (100) and the rotary table (200) through the guide pin (233) inserted into the guide pin hole (232), the position of the diamond segment mold (230) of the rotary table (200) is controlled to be accurately positioned at the first station (110) to the fourth station (140) of the multi-station (100), thereby aligning and preventing the positions of the diamond segment mold (230) and the multi-station (100) from being misaligned due to a malfunction of the sensor or an electrical error as the rotary table (200) rotates repeatedly.
[0115]
[0116] Meanwhile, the diamond segment mold (230) needs to accurately recognize which station is located when the rotary table (200) rotates.
[0117]
[0118] To this end, the present invention may be provided with a mold recognition unit (900) provided on the rotary table (200), and the mold recognition unit (900) may be positioned between each fitting unit (210) on the rotary table (200).
[0119]
[0120] Referring to FIG. 5, the mold recognition unit (900) may be configured to include a detection member (910) that is fastened to a set position on the upper surface of the rotary table (200), a detection sensor (920) that detects the detection member (910), and an index unit (930) that corrects an angle according to the rotation of the rotary table (200).
[0121]
[0122] Here, the sensing member (910) may be a sensing member (910) that is fastened to the rotary table (200), and the sensing member (910) may be fastened to protrude from the upper surface of the rotary table (200) by a set height.
[0123]
[0124] At this time, the above detection member (910) may be formed in multiples corresponding to the number and multiple of the stations and may be provided on the rotary table (200) at a set position.
[0125]
[0126] Accordingly, the above detection sensor (920) can detect the detection member (910) having a different height to recognize the mold number, i.e. the position of the corresponding mold, and can be applied as a detection load.
[0127]
[0128] Meanwhile, the detection sensor (920) may be configured to include a lamp (921) that allows the user to visually confirm that the detection member (910) is located at the corresponding position.
[0129]
[0130] The above index part (930) may be configured to include an index pin (index pin, 931) configured on the upper portion of the rotary table (200) and vertically moved up and down, a hydraulic cylinder (932) configured to move the index pin (931) up and down, and an index pin insertion hole (933) configured on the rotary table (200) and vertically formed between diamond array segment molds into which the downward index pin (931) is vertically inserted.
[0131]
[0132] To this end, the index pin (931) is moved downward using a hydraulic cylinder (932) to insert the index pin (931) into the index pin insertion hole (933) to fix the rotary table (200). Accordingly, by configuring each multi-station (100) to perform a process while the rotary table (200) is fixed, it is possible to prevent safety accidents caused by misalignment of the corresponding angles and positions of the multi-station (100) and the diamond segment mold (230) due to software errors or repeated rotation of the rotary table (200).
[0133]
[0134] Meanwhile, the guide pin (233) formed on the upper surface of the diamond segment mold (230) may be configured to be moved downward while the index pin (931) is lowered and inserted into the index pin insertion hole (933) so that the guide pin (233) is inserted into the guide pin hole (232).
[0135]
[0136] Afterwards, it is possible to adjust the angle and position of the multi-station (100) and the diamond segment mold (230) to correspond to each other so that both the index pin (931) and the guide pin (233) are lowered and inserted into the index pin insertion hole (933) and the guide pin hole (232), respectively, so that the diamond array segment manufacturing device can be prevented from being damaged due to the alignment angle of the multi-station (100) and the diamond segment mold (230) being misaligned due to repeated rotation of the rotary table (200).
[0137]
[0138] The above filling unit (300) is installed at a corresponding station in the multi-station (100) and, when the diamond segment mold (230) rotates and is positioned at a set position, it fills metal powder and diamond into the diamond segment mold (230).
[0139]
[0140] The above filling unit (300) may be configured to include a metal powder filling unit (400) and a diamond array filling unit.
[0141]
[0142] At this time, the filling unit (300) is configured in a linear or radial manner depending on the method of moving to the diamond segment mold (230), and the structure of the metal powder supply unit (410) may be configured differently depending on the method of moving the filling unit (300). In the present invention, it is preferred that the method of moving the filling unit (300) has a linear structure, but as illustrated in FIG. 10, the method of moving the filling unit (300) may be configured in a radial manner.
[0143]
[0144] To this end, the filling unit (300) moving in a straight line moves forward and backward by a moving unit (512) described later, and the filling unit (300) rotating radially can rotate by a preset angle around a rotation axis (310).
[0145]
[0146] Accordingly, the radially rotating filling part (300) is configured as a left and right pair centered on a rotation axis (310), and can rotate by a preset angle by a rotation motor (not shown) configured on the rotation axis (310). At this time, a slide arm (320) capable of adjusting the position of the filling part (300) is configured on the rotation axis (310), so that the filling part (300) can be controlled according to the position of the diamond segment mold (230).
[0147]
[0148] Referring to FIGS. 6 and 7, the metal powder filling unit (400) is configured to supply metal powder to a certain depth into the diamond segment mold (230) and fill the same, and can supply metal powder through the metal powder supply unit (410).
[0149]
[0150] Accordingly, FIG. 6 illustrates a metal powder supply unit (410) when the movement method of the filling unit (300) is configured in a straight line, and FIG. 7 illustrates a metal powder supply unit (410) when the movement method of the filling unit (300) is configured in a radial line.
[0151]
[0152] Meanwhile, the shank and the diamond array segment are integrated by laser welding at their contact surfaces, but in this case, considering the problem that the laser is reflected by the diamond of the diamond array segment and welding is not performed, the present invention can form a blank area without diamond on one side of the diamond array segment that comes into contact with the shank for integration when integrating the shank and the diamond array segment.
[0153]
[0154] Accordingly, the metal powder filling unit (400) can form a blank area when supplying metal powder.
[0155]
[0156] Referring to Fig. 8, four diamond segment molds (230) are formed in a 2×2 array, and when the movement method of the filling part (300) is linear, the forming hole (231) is formed in a square shape as shown in (c) of Fig. 8, and when the movement method of the filling part (300) is radial, the forming hole (231) is formed in a fan shape as shown in (a), (c), and (d) of Fig. 8.
[0157]
[0158] To this end, the metal powder filling unit (400) may be arranged in the order of metal powder supply hopper (411, B) - blank (A) - metal powder supply hopper (411, B) so that a blank area (A) is formed on one side (inner side) of the diamond segment mold (230), and may be formed so that the entire area becomes a blank area (A) as shown in (b) of FIG. 8.
[0159]
[0160] Meanwhile, when the diamond segment mold (230) is formed in a fan shape, the metal powder filling unit (400) can be arranged in the order of blank (A) - metal powder hopper (411, B), blank (A) - metal powder hopper (411, B) so that the blank area (A) is formed on only one side, and the entire diamond segment mold (230) can be formed as the blank area (A).
[0161]
[0162] Here, the metal powder filling unit (400) is equipped with a powder division adapter (412) at the inlet of the metal powder supply hopper (411) that supplies metal powder, so that a blank area can be effectively formed.
[0163]
[0164] Meanwhile, by supplying metal powders having different particles or types into each of the plurality of metal powder hoppers (411), the metal powders filled into the forming hole (231) are configured to be of different types stacked, so that various types of diamond cutting segments can be produced in response to the type of cutting material or industrial site.
[0165]
[0166] Referring to FIG. 9, the diamond setting unit (500) is configured to supply and arrange diamonds into the diamond segment mold (230), and may include a diamond supply unit (510) and a removal unit (520).
[0167]
[0168] The above diamond supply unit (510) is located at the second station (120) for arranging diamonds and can move forward and backward toward the diamond segment mold (230), and after sucking in the diamonds, can supply them in an array into the diamond segment mold (230).
[0169]
[0170] The above diamond supply unit (510) may be configured to include a transfer body (511), a vacuum suction unit (513) connected to the transfer body (511) to suck up diamonds, a moving unit (512) connected to the transfer body (511) to move the transfer body (511) forward and backward, and a removal unit (520) for removing residual diamonds attached to the transfer body (511).
[0171]
[0172] Referring to FIG. 11, the transport body (511) includes a supply member (515) having a plurality of array grooves (516) formed on the lower surface, and can cause diamonds to be sucked into the array grooves (516) by vacuum.
[0173]
[0174] Here, the above array groove (516) can be formed in a specific arrangement by design so that diamonds can be supplied according to a specific arrangement.
[0175]
[0176] Here, the diamond supply unit (510) may be configured to include a receiving portion (514) that is open at the top and receives diamonds at the bottom of the transport body (511) so that the diamonds are sucked into the transport body (511).
[0177]
[0178] The above vacuum suction unit (513) is connected to the transfer body (511) and can suck in diamonds to fill the arrangement groove (516) and discharge them so that the diamonds can be arranged in the metal powder filled in the diamond segment mold (230).
[0179]
[0180] The above moving unit (512) has a role of moving the transfer body (511) forward and backward according to the control signal of the operation control unit (800), and can move forward after sucking in the diamond to supply and arrange the diamond to the diamond segment mold (230) and then move backward to return to the original position.
[0181]
[0182] Meanwhile, the above-mentioned receiving portion (514) is manufactured in various sizes, and the sizes of the array grooves (516) are also formed to be different from each other so that multiple diamonds of various sizes can be supplied, thereby improving the lifespan and cutting power of the diamond cutting segment.
[0183]
[0184] The above removal unit (520) serves to remove and collect the remaining diamonds attached to the transfer body (511), and enables the diamond supply unit (510) to arrange the diamonds in a desired amount at an accurate location on the pre-filled metal powder.
[0185]
[0186] The above removal unit (520) may be configured to include a shock rod (521) and a brush (522).
[0187]
[0188] The above shock rod (521) can be configured to apply a light shock to the lower portion of the transport body (511) so that the diamond attached to the transport body (511) falls downward.
[0189]
[0190] The above shock rod (521) is configured as a pair to apply an even shock to the left and right sides of the plane of the transport body (511) and can apply an shock to both sides of the transport body (511).
[0191]
[0192] The above brush (522) can secondarily remove residual diamonds by sweeping the lower surface of the transfer body (511) as the transfer body (511) moves forward toward the diamond segment mold (230).
[0193]
[0194] According to the above, the removal unit (520) can primarily remove the remaining diamonds attached to the transfer body (511) by the impact rod (521), and secondarily remove the remaining diamonds through the brush (522) as the transfer body (511) moves forward toward the diamond segment mold (230).
[0195]
[0196] Meanwhile, when diamonds are arranged in this way on metal powder, it is necessary to maintain the arrangement of diamonds by compacting the metal powder and diamonds so that the arrangement of diamonds is not disturbed.
[0197]
[0198] Accordingly, considering that when metal powder and diamond are simply stacked, the arrangement of the diamonds may become scattered due to the metal powder that is subsequently filled, the metal powder and diamond filled in the diamond segment mold (230) can be pressed at a certain pressure through the compaction unit (600) to maintain the arrangement of the diamonds at a certain level.
[0199]
[0200] The above compaction unit (600) is installed on the upper side of the rotary table (200), and a press rod having a plane shape corresponding to the plane shape of the diamond segment mold (230) is positioned on the upper side of the array segment rod so that the metal powder and the diamond filled in the diamond segment mold (230) can be pressed while moving from the upper side to the lower side.
[0201]
[0202] The above pressurized extraction unit (700) is installed on the upper side of the rotary table (200) and, when metal powder and diamond are filled in multiple layers, serves to shape the filled metal powder and diamond into a diamond array segment and then extract them.
[0203]
[0204] Referring to FIG. 12, the pressurized extraction unit (700) may be configured to include a pressing unit (710), an extraction unit (720), and an extraction operation unit (730).
[0205]
[0206] Here, the pressing unit (710) and the extraction unit (720) pressurize the metal powder and the diamond filled in the diamond segment mold (230) at a set pressure. At this time, the pressing unit (710) and the extraction unit (720) can be formed so that they can form the diamond array segment by applying the same set pressure to each other.
[0207]
[0208] The above pressing unit (710) may be configured to be positioned above the diamond segment mold (230) and pressurize from the top to the bottom.
[0209]
[0210] The above extraction unit (720) pressurizes the filled metal powder and the diamond at the same set pressure as the pressing unit (710), and then extracts the formed diamond array segment.
[0211]
[0212] The above extraction operation unit (730) can operate the extraction unit (720) to extract the formed diamond array segment by limiting the length of movement of the extraction unit (720) in the downward direction by the pressure of the pressing unit (710).
[0213]
[0214] To this end, the extraction operation unit (730) may be configured to include a pressure support plate (731) that moves downwards along with the extraction unit (720) by the pressurization of the pressing unit (710), a fixed stopper (732) that limits the distance by which the pressure support plate (731) moves downwards, a pair of elastic restoring parts (733) that restore the pressure support plate (731) to its initial position when the pressing unit (710) is completed, and an extraction sub-motor (734) that moves the extraction unit (720) upwards to extract the diamond array segment when the pressurization of the pressing unit (710) and the extraction unit (720) is completed and the diamond array segment is formed.
[0215]
[0216] According to the above, when the pressing unit (710) pressurizes the metal powder and the diamond filled in the diamond segment mold (230) at a set pressure, the extraction unit (720) moves vertically downward together with the diamond segment mold (230), and the pressure support plate (731) configured at the bottom of the extraction unit (720) moves downward together.
[0217]
[0218] Afterwards, the pressure support plate (731) moves downward and when the movement is stopped by the fixed stopper (732), the movement of the pressure support plate (731) also stops, so that the same pressure as the set pressure of the pressing part (710) is applied to the extraction part (720), so that the metal powder and the diamond can be pressed at the same set pressure from the top and bottom.
[0219]
[0220] When the forming of the diamond array segment is completed by pressing the metal powder and the diamond, the pressing unit (710) moves upward, and the pressure support plate (731) moves to the initial position by a pair of elastic restoring units (733) formed of springs, and then the extraction sub-motor (734) moves the extraction unit (720) upward to extract the diamond array segment.
[0221]
[0222] Meanwhile, the present invention may further include a cleaning unit (not shown) for removing impurities inside the diamond segment mold (230) after the extraction of the diamond array segment is completed as described above.
[0223]
[0224] The above cleaning unit is preferably located at the second station (120), but may be located at another station depending on the usage environment and needs, and various configurations may be applied as long as they can effectively remove impurities within the diamond segment mold (230).
[0225]
[0226] The above operation control unit (800) receives the station position information from the mold recognition unit (900) and rotates the rotary table (200) so that the diamond segment mold (230) is positioned at a set position, controls the operation of each station so that the metal powder and the diamond are filled into the diamond segment mold (230), and controls the operation of the filling unit (300), and controls the operation of the compaction unit (600), the pressing unit (710), the extraction unit (720), and the extraction operation unit (730).
[0227]
[0228] Here, the operation control unit (800) may be configured to include a display device and a control panel (810; see FIG. 1) so that the manager can effectively control the operation of each station of the multi-station (100) and the rotation of the rotary table (200).
[0229]
[0230] Below, a method for manufacturing a diamond array segment using the above-mentioned diamond array segment manufacturing device will be examined.
[0231]
[0232] The method for manufacturing a diamond array segment according to an embodiment of the present invention can first fill metal powder in step (1) after preparing for filling, such as removing residue inside a diamond segment mold (230).
[0233]
[0234] Once the metal powder is filled in this way, diamonds can be filled and arranged in step (2).
[0235]
[0236] When the diamonds are arranged in the metal powder filled in the diamond segment mold (230) in this way, the diamonds can be pressed at a preset pressure in the subsequent step (3), which is the compacting step, so that the diamonds are embedded in the metal powder.
[0237]
[0238] Here, the compacting process is a necessary operation to fill the metal powder while maintaining the diamond arrangement in a constant state, because if the metal powder and diamond are simply stacked, the diamond arrangement may become scattered due to the metal powder that is then filled.
[0239]
[0240] Step (4) thereafter can form multiple layers according to the settings by repeating steps (2) and (3).
[0241]
[0242] In the present invention, unlike the conventional method of forming a single layer of metal powder and diamond and then molding, multiple layers (a total of 8 to 9 layers) can be formed with a metal powder and diamond array, and through this process, a metal powder layer can be formed on both sides of a diamond array segment.
[0243]
[0244] By filling the metal powder and diamond in this way to form a setting layer, (5) the diamond array segment can be pressed and formed.
[0245]
[0246] After (6), the formed diamond array segment is extracted, and the formed diamond array segment can be finished by baking at a set high temperature.
[0247]
[0248] Meanwhile, for each process described above, a method for manufacturing a diamond array segment according to an embodiment of the present invention will be described by taking as an example a case in which the above-described configurations are installed at the corresponding locations for each station in the multi-station (100).
[0249]
[0250] First, the multi-station (100) can be arranged in a circular shape on a plane corresponding to a rotary table (200) in which four stations rotate 360 degrees, and each station can be sequentially positioned as the first station (110) to the fourth station (140).
[0251]
[0252] Here, looking at each station, the first station (110) may be configured with a pressurized extraction unit (700) to enable pressing and extraction, the second station (120) may be configured with a diamond setting unit (500) located adjacent to the clockwise direction of the first station (110) to enable setting of diamonds, the third station (130) may be configured with a compaction unit (600) and a cleaning unit located adjacent to the clockwise direction of the second station (120) to enable preparation and compaction, and the fourth station (140) may be configured with a metal powder filling unit (400) located adjacent to the clockwise direction of the third station (130) and adjacent to the counterclockwise direction of the first station (110) to enable filling of metal powder.
[0253]
[0254] Here, a detailed look at the method for manufacturing diamond array segments according to each station for the diamond segment mold (230) coupled to the rotating rotary table (200) is as follows: first, filling preparation is performed starting from the third station (130), and then, by rotating, metal powder is filled into the diamond segment mold (230) at the fourth station (140), and after rotating, it passes through the first station (110) and the diamonds can be arranged at the second station (120).
[0255]
[0256] When the diamonds are arranged in this way at the second station (120), they are rotated to be compacted at the third station (130), and after passing through the fourth station (140) and the second station (120) by rotation, the second station (120), the third station (130), and the fourth station (140) are repeated to form multiple layers. After the set multiple layers are formed, the diamond array segments can be pressed and extracted at the first station (110) by rotation.
[0257]
[0258] Although the present invention has been described above with reference to preferred embodiments thereof, it will be apparent to those skilled in the art that various modifications and changes may be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
[0259]
[0260] The present invention is not limited to the specific preferred embodiments described above, and anyone with ordinary skill in the art to which the invention pertains can make various modifications without departing from the gist of the present invention claimed in the claims, and as long as it relates to technical ideas forming such modifications, it is within the scope of the claims.
