Description

Vertical composite tool system of product transfer device for press forming of carbide insert products

[0001] The present invention relates to a vertical composite tool system of a product transport device for press molding of a carbide insert product, and more specifically, to a vertical composite tool system configured to improve productivity and quality of a product by including a grip part for taking out a carbide insert product from a press for molding the carbide insert product and a clean part for cleaning the upper and lower surfaces of a mold.

[0002] In general, cutting tools are mainly used for cutting ferrous, non-ferrous metals, and non-metallic materials, and are tools that are usually mounted on machine tools to perform cutting to process a workpiece into a desired shape.

[0003] Carbide inserts used in cutting tools are sintered alloys formed by mixing diamond powder or carbide powder with metal powders such as iron (Fe), tungsten (W), cobalt (Co), copper (Cu), nickel (Ni), tin (Sn), copper-tin (CuSn), zinc (Zn), copper-zinc (CuZn), and silver (Ag).

[0004] The molding step prior to sintering involves placing a mixed powder in a rectangular cavity and performing a primary pressurized molding. The primary pressurized mixture is then placed in the cavity of a carbon mold and a puncher is used to apply high pressure to form a cutting tip having a shape corresponding to the shape of the puncher. By sintering the insert tip formed into a certain shape in a sintering furnace, a diamond insert tip or insert tip is completed.

[0005] The above molding step requires a cleaning device to clean the top and bottom surfaces of the mold, and a pickup device to remove the molded carbide insert product from the mold and transfer it to a pallet. Conventional molding presses have separate cleaning devices and pickup devices.

[0006] The applicant of the present invention has applied for and received registration of a 'composite tool system of a product transport device for press molding of a carbide insert (Application No. 10-2019-0076032, Application Date 2019.06.26.)' in which the grip portion and the clean portion are formed together. The invention is configured to have excellent rotational force of a brush using compressed air and to tilt the brush when taking out a product so as not to interfere with the work. However, since the grip portion and the clean portion are arranged side by side at the tip, the overall external dimensions are increased, and there are still problems such as interference with peripheral devices when working in a narrow molding space.

[0007] The applicant has developed a vertical composite tool system capable of producing a large quantity of high-quality cemented carbide insert products by simultaneously performing an efficient cleaning process and an accurate pick-up process to improve the problems described above in the present invention.

[0008] The purpose of the present invention to solve the above-described problem is to provide a vertical composite tool system of a product transport device for press forming of a carbide insert product, which comprises a grip section for picking up a carbide insert product formed in a forming press and transporting it to the next process on one side of a frame in the longitudinal direction, a clean section formed on the same line in the longitudinal direction with the grip section on the frame for cleaning upper and lower forming molds, and a drive section for rotating the grip section and the clean section forward and backward.

[0009] Another object of the present invention is to provide a vertical composite tool system of a product transport device for press forming of a cemented carbide insert product, the grip part including a gripper module for holding a cemented carbide insert product whose forming has been completed, and an air blower for blowing compressed air along the outer periphery of the gripper module.

[0011] Another object of the present invention is to provide a vertical composite tool system of a product transport device for press forming of a cemented carbide insert product, wherein the brush module comprises an upper mold brush including an upper brush hold for cleaning an upper mold and a lower mold brush including a lower brush hold for cleaning a lower mold.

[0012] Another object of the present invention is to provide a vertical composite tool system of a product transport device for press forming of a carbide insert product, wherein the cylinder body is configured to couple the upper mold brush and the lower mold brush.

[0013] Another object of the present invention is to provide a vertical composite tool system of a product transport device for press forming of a carbide insert product, wherein the driving unit comprises a stepping motor that generates power to rotate the upper mold brush and the lower mold brush forward and backward, a timing belt that transmits the forward and reverse rotational force generated by the stepping motor to the grip part and the clean part, a sensor that controls the grip angle of the gripper module, and a tension roller that adjusts the tension of the timing belt.

[0014] In order to achieve the above purpose, the vertical composite tool system of the product transport device for press molding of the carbide insert product of the present invention is characterized in that one side of the frame in the longitudinal direction is coupled to the main body equipment, the other side is configured to include a grip part that picks up the carbide insert product formed in the molding press and transports it to the next process, a clean part formed on the same line in the longitudinal direction with the grip part on the frame to clean the upper and lower molds, and a driving part that rotates the grip part and the clean part forward and backward.

[0015] Another feature of the vertical composite tool system of the product transfer device for press molding of the carbide insert product of the present invention is that the grip part includes a gripper module for holding the molded carbide insert product, and an air blower for blowing compressed air along the outer periphery of the gripper module.

[0016] Another feature of the vertical composite tool system of the product transfer device for press forming of the carbide insert product of the present invention is that the cleaning section is formed on the same longitudinal line as the grip section of the frame and is configured to include a brush module and a cylinder body to clean the upper forming mold and the lower forming mold.

[0017] Another feature of the vertical composite tool system of the product transfer device for press molding of the carbide insert product of the present invention is that the brush module is composed of an upper mold brush including an upper brush hold for cleaning an upper mold and a lower mold brush including a lower brush hold for cleaning a lower mold.

[0018] Another feature of the vertical composite tool system of the product transfer device for press forming of the carbide insert product of the present invention is that the cylinder body is configured such that the upper mold brush and the lower mold brush are combined.

[0020] As described above, the vertical composite tool system of the product transport device for press molding of a carbide insert product according to the present invention is configured such that the grip section for removing the carbide insert product and the cleaning section for cleaning the mold are arranged along the same longitudinal line. Accordingly, the overall external width of the vertical composite tool system is reduced, thereby providing a system with excellent work efficiency in a narrow molding space.

[0021] In addition, the vertical composite tool system of the product transport device for press molding of a carbide insert product according to the present invention is configured to vertically raise and conceal the lower brush toward the inside of the frame when picking up the carbide insert product, and to vertically lower and expose the lower brush when cleaning the mold. Therefore, compared to the horizontally tilting brush structure of the prior art, it has the advantages of better space utilization and no interference with peripheral devices.

[0022] Furthermore, the vertical composite tool system of the product transport device for press forming of a carbide insert product according to the present invention comprises a grip section and a cleaning section positioned at the front and rear of the frame lengthwise, and a drive section simultaneously driven by a single timing belt. Therefore, the drive section configuration is simpler than that of conventional composite tool devices, enabling the provision of a high-performance vertical composite tool system with superior quality and price competitiveness.

[0031] The present invention can have various modifications and embodiments, and specific embodiments are illustrated in the drawings and described in detail in the description of the invention.

[0032] However, this is not intended to limit the present invention to specific embodiments, but should be understood to include all modifications, equivalents, and substitutes included in the spirit and technical scope of the present invention.

[0033] The terms and words used in this invention are used solely to describe specific embodiments and are not intended to limit the invention. Based on the principle that the concepts of terms can be appropriately defined to best explain the invention, they should be interpreted in a way that aligns with the technical spirit of the invention.

[0034] The vertical composite tool system of a product transfer device for press forming of a carbide insert product according to the present invention is responsible for the function of taking out a formed carbide insert product by combining with or approaching an existing forming press device, performing a deburring process, and transferring it to a sintering plate for a sintering process.

[0035] The vertical composite tool system of the product transfer device for press forming of a superhard insert product according to the present invention is configured to perform a work command issued from a controller (not shown) of the transfer device through a slave (12) that is coupled to a robot (X-axis, Y-axis, Z-axis) and transmits a pneumatic or electrical signal.

[0036] The product transport device for existing press molding has a 'gripper tool' and a 'clean tool' placed separately, and normally, the molded carbide insert product is taken out with the gripper tool, but when the mold needs to be cleaned, the process is carried out by replacing it with a clean tool through the ATC (Auto Tool Changer).

[0037] In order to improve the above-mentioned problems, the applicant has applied for a 'composite tool system of a product transfer device for press molding of a carbide insert (application number 10-2019-0076032, application date 2019.06.26.)' in which the gripper tool and the clean tool are formed together.

[0038] Referring to Fig. 1, the prior art invention of the present applicant is briefly described as follows. The prior art composite tool system (1) comprises a grip section (1.1) and a cleaning section (1.2) arranged horizontally side by side at the front end of the frame. The grip section (1.1) comprises a gripper (1.11) for gripping and removing a molded carbide insert product, a stepping motor (1.13) for controlling the gripping angle of the gripper (1.11) and the loading angle of the pallet, and a gripper rotation belt (1.12) for connecting the stepping motor (1.13) and the gripper (1.11) to transmit driving force.

[0039] In addition, the cleaning section (1.2) is configured to include upper and lower brushes (1.21) configured to simultaneously clean the upper and lower molds, a tilting cylinder (1.22) that can tilt the brush (1.21) during grip work, a forward and reverse rotation motor (1.24) that rotates the brush (1.21) forward and reverse during clean work, and a brush rotation felt (1.25) that transmits the driving force of the forward and reverse rotation motor (1.24) to the brush (1.21).

[0040] As described above, the structure in which the grip portion and the cleaning portion are arranged horizontally at the tip portion has problems such as interference with peripheral devices when working in a narrow molding space due to the increased overall external dimensions.

[0041] The present applicant has developed a high-performance, high-quality vertical composite tool system that solves the above-described problems by rearranging the grip section and the cleaning section.

[0042] Specific features and advantages of the vertical composite tool system of the product transport device for press forming of a carbide insert product according to the present invention will be more clearly explained below with reference to the attached drawings.

[0044] Referring to FIGS. 2 and 3, a vertical composite tool system of a product transport device for press molding of a carbide insert product according to the present invention comprises a grip part (100) having one longitudinal side of a frame (11) coupled to a main body equipment, the other side being a tip part for picking up and taking out a carbide insert product formed in a molding press and transporting it to the next process, a clean part (200) formed on the same longitudinal line of the grip part (100) on the frame (11) for cleaning the upper and lower molds, and a drive part (300) for rotating the grip part (100) and the clean part (200) forward and backward.

[0045] Referring to FIGS. 4 and 7, the grip part (100) of the vertical composite tool system of the product transfer device for press molding of a cemented carbide insert product according to the present invention is configured to include a gripper module (110) that holds a molded cemented carbide insert product, and an air blower (120) that blows compressed air along the outer periphery of the gripper module (110).

[0046] At this time, the gripper module (110) according to the present invention applies a gripper (111) of an encounter method and a vacuum method, and when applying the encounter method and the vacuum method, a pneumatic line is configured to operate by pneumatic pressure.

[0047] The superhard insert product that is extracted and gripped by the gripper module (110) according to the present invention is placed on a sintering plate for the sintering process after removing dust from the surface in a deburring process.

[0048] At this time, in order to increase the deburring efficiency, compressed air is ejected from the air blower (120), and in order to accurately load the superhard insert product, a stepping motor (310) capable of minute rotation and a timing belt (320) are configured. (Described in the driving section below)

[0049] Referring to FIGS. 5 to 7, the cleaning section (200) of the vertical composite tool system of the product transfer device for press molding of a superhard insert product according to the present invention is configured to include a brush module (210) and a cylinder body (220) formed on the same longitudinal line as the grip section (100) of the frame (11) to clean the upper mold and the lower mold.

[0050] The brush module (210) of the present invention is composed of an upper mold brush (211) including an upper brush hold (211.1) to clean an upper mold and a lower mold brush (213) including a lower brush hold (213.1) to clean a lower mold.

[0051] In addition, on the outer surface of the lower brush hold (213.1) of the present invention, a brush hold guide (213.2) is formed in flat contact with the inner wall of the 'lower cylinder' of the cylinder body (220) to transmit positive and negative rotational force and prevent idling.

[0052] The cylinder body (220) of the present invention is configured such that the upper mold brush (211) and the lower mold brush (213) are combined.

[0053] At this time, the upper mold brush (211) of the brush module (210) is configured to be fastened to the upper cross-section of the cylinder body (220), and the lower mold brush (213) is configured to be hidden by rising vertically on the inside of the frame (11) when the grip part (100) performs a 'pick-up operation', and to be exposed by descending vertically when 'molding cleaning' is performed.

[0054] In addition, the cylinder body (220) of the present invention is formed so that an 'upper cylinder' and a 'lower cylinder' having different inner diameters vertically penetrate each other, and the 'upper cylinder' is configured in a cylindrical shape, and the 'lower cylinder' transmits a positive and negative rotational force to a lower mold brush (213) that is slidably coupled, and a flat contact surface is formed on the inner wall to prevent idling.

[0055] In the 'upper cylinder' of the cylinder body (220) of the present invention, a single-stage slider (230) in the form of a cylindrical cylinder is coupled so as to be able to perform an up-and-down reciprocating sliding motion, and in the 'lower cylinder', a lower brush holder (213.1) to which a lower mold brush (213) is fastened is coupled so as to be able to perform an up-and-down reciprocating sliding motion.

[0056] In addition, at the center of the lower brush holder (213.1), a sliding rod (240) that can perform an up-and-down reciprocating sliding motion by being coupled to the cylindrical cylinder of the first slider (230) is fastened.

[0057] At this time, looking at the internal configuration of the cylinder body (220), from above, a single-stage slider (230) configured to perform an up-and-down reciprocating motion in the 'upper cylinder', a sliding rod (240) configured to perform an up-and-down reciprocating motion by being coupled to the slider (230) in a cylinder shape, a lower brush holder (213.1) fastened to the sliding rod (240), and a lower mold brush (213) coupled to the lower brush holder (213.1) are connected in that order, and an O-ring (not provided) is coupled to each component to perform a sealing function so that an up-and-down reciprocating sliding motion can be performed by operating air.

[0058] Looking into the exposure (mold cleaning) and concealment (pick-up operation) of the lower mold brush (213) of the present invention in detail, during 'mold cleaning', operating air is injected into the inside (upper cylinder) of the cylinder body (220) through the air pit (not provided) and the pneumatic line connected to the fixed boss (216), so that the first-stage slider (230) and the sliding rod (240) are simultaneously moved downward, and the lower mold brush (213) is lowered and put into a mold cleaning preparation state (exposure). In addition, during the 'pick-up operation', operating air injected through another pneumatic line is injected into the space between the sliding rod (240) and the first-stage slider (230) and the space between the first-stage slider (230) and the cylinder body (220), so that the sliding rod (240) and the first-stage slider (230) are raised, thereby concealing the lower mold brush (213) inside the frame (11). (See Figs. 5 and 6)

[0059] Referring to FIG. 8, the driving unit (300) of the vertical composite tool system of the product transfer device for press molding of a carbide insert product according to the present invention is configured to include a stepping motor (310) that generates power to rotate the upper mold brush (211) and the lower mold brush (213) forward and backward, a timing belt (320) that transmits the forward and reverse rotational force generated by the stepping motor (310) to the grip unit (100) and the clean unit (200), a sensor (330) that controls the grip angle of the gripper module (110), and a tension roller (340) that adjusts the tension of the timing belt (320).

[0060] The timing belt (320) of the present invention is configured so that the gripper module (110) and the brush module (210), which are positioned on the same line in the longitudinal direction of the frame (11), can perform positive and negative rotational movements simultaneously.

[0061] Looking at the transmission of the forward and reverse rotational power of the driving unit (300) of the present invention in detail, the gripper module (210) of the grip unit (100) and the brush module (210) of the cleaning unit (200) are formed on the same longitudinal line of the frame (11), and are configured to be driven simultaneously by being connected to the stepping motor (310) that generates the driving power and the timing belt (320).

[0062] The positive and negative rotational force transmitted to the gripper module (110) controls the posture by rotating the gripper (111) by a pulley (112). In addition, the positive and negative rotational force transmitted to the brush module (210) is transmitted to the cylinder body (220) supported for rotation by a bearing (218) through a pulley (217), and ultimately performs 'mold cleaning' by rotating the upper mold brush (211) and the lower mold brush (213) positively and negatively.

[0063] At this time, the brush hold guide (213.2) formed on the outer surface of the lower brush hold (213.1) is configured to contact the inner wall of the 'lower cylinder' of the cylinder body (220) in a flat manner to transmit the positive and negative rotational force of the driving unit to the lower mold brush (213) and prevent idling.

[0064] The vertical composite tool system of the product transfer device for press forming of a superhard insert product according to the present invention has the following characteristics.

[0065] The vertical composite tool system of the present invention is configured to place a grip part for extracting a carbide insert product and a clean part for cleaning a mold on the same line in the longitudinal direction.

[0066] Accordingly, the overall external width of the vertical composite tool system can be reduced, thereby providing a system with excellent work efficiency in a narrow molding space.

[0067] In addition, the vertical composite tool system of the present invention is configured to vertically raise and conceal the lower brush toward the inside of the frame when picking up a carbide insert product, and to vertically lower and expose the lower brush when cleaning the mold.

[0068] Therefore, compared to the horizontal tilting brush structure of the conventional invention, it has the advantage of good space utilization and no interference with peripheral devices.

[0069] In addition, the vertical composite tool system of the present invention has a grip section and a cleaning section positioned at the front and rear of the frame length direction, and a driving section simultaneously driven by a single timing belt.

[0070] Therefore, a high-performance vertical composite tool system with superior quality and price competitiveness can be provided because the configuration of the driving unit is simpler than that of a conventional composite tool device.
