The present invention relates to a dual grip device for transferring cemented carbide press products, and more particularly, to a first grip for transferring an insert tip formed in a press to a meter, and a second grip for transferring the inspected insert tip from a meter to a platform. The present invention relates to a dual grip device for conveying cemented carbide press products, which is configured to improve work speed and productivity.

In general, a cutting tool is mainly used for cutting iron-based, non-ferrous metals, and non-metallic materials, and generally refers to a tool mounted on a machine tool to perform cutting to process a workpiece into a desired shape.

The insert tip used in these cutting tools is a diamond powder or a cemented carbide powder, iron (Fe), tungsten (W), cobalt (Co), copper (Cu), nickel (Ni), tin (Sn), copper It is composed of a small bond alloy which is formed by mixing and molding with metal powders such as tin (CuSn), zinc (Zn), copper-zinc (CuZn), silver (Ag) and the like.

In the forming step before firing the insert tip, a mixed powder is put into a cubic cavity and firstly press-molded, and a first press-molded mixture (hereinafter referred to as a primary press-molded product) is placed in a cavity of a carbon mold. (Puncher) is press-molded a cutting tip of a shape corresponding to the shape of the puncher while applying a relatively large pressure.

Subsequently, the diamond insert tip or the cemented carbide insert tip is completed by firing the cutting tip formed into a constant shape in a sintering furnace.

Next, the mass is measured by transferring to the weighing machine to measure the mass of the insert tip pressed, and if the measurement result is good within the standard range, the insert tip is transferred back to the flat platform to arrange the insert tips at regular intervals for the post process.

Of course, if the mass measurement result is out of the standard range it is transferred to the defective storage case and dropped.

In this case, as a means for transferring the insert tip from the press to the meter for mass measurement, and again from the meter to the platform, a grip device for transferring a press product for cemented carbide is used.

However, the conventional grip device adopts a grip for insert insert as a single grip, which causes a decrease in productivity as the time for transferring the insert tip is accumulated.

That is, the single grip of the conventional grip device transfers forward to the press to pick up the processed insert tip in the press, and the single grip moves backward to the meter located at the back of the press, and puts it on the weighing machine for mass measurement. As the completed insert tip is retracted by the unitary grip and then retracted to the platform behind the meter and seated on a flat platform, the insert tip accumulates, resulting in a decrease in the insert tip's productivity. .

Thus, as the conventional single grip sequentially moves back and forth between the press, the meter, and the platform by the dividing operation, the transfer and loading time of the insert tip is inevitably long, and thus the productivity of the insert tip decreases. have.

The X1 axis transfer driving means 18 is disposed, and the X1 axis robot 20 extending in the forward direction is connected to the output end of the X1 axis transfer driving means 18.

At this time, the lower end of the Z1-axis transfer frame 16 is integrally coupled to the upper surface of the rear end of the X1-axis robot 20 which is integrally connected to the X1-axis transfer drive means 18 and extends forward, and thus the X1-axis robot 20 ) Is moved up and down along the Z1 axis with the Z1-axis feed frame (16).

In addition, the first grip holder frame 22 which is raised and lowered along the Z1 axis is integrally mounted at the bottom of the front end of the X1-axis robot 20 when the Z1-axis feed frame 16 is lowered.

In addition, a bottom surface of the first grip holder frame 22 is equipped with a first grip 26 for picking up and inserting the insert tip 24 formed by the press 100 to the meter 102. 26) may be mechanical gripper for mounting the insert tip by mechanical movement, vacuum picking by vacuum suction, magnet picking by magnetic force, and the like.

On the other hand, on the X1 axis robot 20 X1 axis transfer frame 30 which is moved back and forth along the X1 axis by various driver media 28, such as a belt driver or screw driver that receives power from the X1 axis transfer driving means 18 ) Is mounted.

In particular, the X1 axis transfer frame 30 is equipped with a second grip lifting means 40 for driving the second grip 32 up and down along the Z2 axis direction.

More specifically, as one configuration of the second grip lifting means 40, the up-down motor 41 is fixedly mounted on the upper end of the X1-axis feed frame 30, and the lower output shaft 42 of the up-down motor 41 is mounted. ), The lifting rod 32 is mounted to be freely rotatable.

At this time, the lower end of the elevating rod 43 passes through the bottom of the X1-axis transfer frame 30, the second grip 32 for picking up the insert tip 24 of the meter 102 and transported to the platform 104 ) Is integrated with.

In addition, as another configuration of the second grip up and down end 40, it is mounted up and down on the portion adjacent to the output shaft 42 of the up-down motor 41, and is raised and lowered to the output shaft 42 of the up-down motor 41. In other words, the elevating distance detecting sensor 44 for detecting the elevating distance of the second grip 32 connected via the output shaft 42 and the elevating rod 32 substantially.

On the other hand, since the insert tip 24 is molded in a triangular shape, when arranged on the platform 104, the insert tip 24 as shown in the accompanying drawings for densely arranging more insert tips 24 is shown. It is desirable to stagger the hypotenuses and the hypotenuses.

To this end, as a means for switching to the seating direction of the insert tip 24 seated on the platform 104, the means for switching the grip direction of the insert tip 24 by rotating the second grip 32 is X1 axis It is mounted to the transfer frame (30).

As a configuration for switching the grip direction of the insert tip 24 by rotating the second grip 32 angularly, the turning motor 45 is mounted on the bottom of the X1-axis feed frame 30, and the turning motor ( A drive gear 46 is mounted on the output shaft of 45).

In addition, the turning gear 47 is mounted on the lower end of the elevating rod 43 which is connected to the second grip 32 and penetrates the bottom of the X1-axis feed frame 30 to be positioned directly above the second grip. The driving gear 46 and the turning gear 47 are connected to the timing belt 48 so as to transmit power.

Here, the operation flow of the dual grip device for transporting cemented carbide press products of the present invention having the above configuration will be described with reference to FIGS. 1 to 5 as well as FIGS. 6 and 7.

First, when the insert tip 24 is press-molded in the press 100, the molded insert tip 24 is picked up and transferred to the meter 102.

To this end, when the Y-axis rail 12 advances along the X2-axis rail 10, the Z1-axis robot 14 mounted on the Y-axis rail 12 so as to be movable left and right, and the front surface of the Z1-axis robot 14 X1 axis robot 20 integrally coupled to the lower end of the Z1 axis feed frame 16 and the Z1 axis feed frame 16 integrated with the slider 15, the slider 15 mounted to be able to move up and down And the first grip holder frame 22 mounted at the bottom of the front end of the X1-axis robot 20 are simultaneously advanced, and the first grip holder frame 22 is positioned on the insert tip 24 of the press 100. Done.

That is, the first grip 26 mounted on the bottom of the first grip holder frame 22 is positioned on the insert tip 24 of the press 100.

Subsequently, by driving the driver medium 13 of the Z1-axis robot 14, the Z1-axis feed frame integrally with the slider 15 and the slider 15 mounted on the Z1-axis robot 14 so as to be lowered and lowered ( When 16 is instantaneously lowered, the X1-axis robot 20 integrally coupled with the lower end of the Z1-axis transfer frame 16 and the first grip holder frame mounted on the bottom of the front end of the X1-axis robot 20 ( 22 is simultaneously lowered along the Z1 direction, and the first grip 26 mounted on the bottom of the first grip holder frame 22 picks up and fixes the insert tip 24 of the press 100.

As described above, the first grip 26 moves forward to the insert tip 24 and descends downward to pick up the insert tip 24, and the first grip 26 moves backward to the meter 102. The tip 24 is placed on the meter 102.

Accordingly, the meter 102 measures the mass of the insert tip 24, and if the measurement result is a good product within the reference range, a subsequent operation process is carried out to the flat platform 104, and the mass measurement result is outside the reference range. Drop it to the defective storage case.

The insert tip 24 determined as good in the meter 102 is transferred to the platform 104 by the second grip 32 which is made at the same time as the operation of the first grip 26, and is arranged to be stacked at regular intervals.

To this end, the second grip 32 is lowered along the Z2-axis direction by the operation of the second grip lifting means 40 to pick up the insert tip 24 on the meter 102.

That is, the output shaft 42 is lowered by the operation of the up-down motor 41, and the lifting rod 43 connected to the output shaft 42 is also lowered, and the second grip 32 connected to the lower end of the lifting rod 43 is provided. ) Is lowered to pick up the insert tip 24 on the meter (102).

Subsequently, the second grip 32 also moves backward to the platform 104 at the same time as the first grip 26 retracts, thereby placing the insert tips 24 on the platform 104 at regular intervals.

At this time, the first grip 26 reciprocates a predetermined moving distance between the press 100 and the meter 102, but the insert tip 24 is first arranged at the rear end of the platform 104 from the meter 102, and then As the insert tips 24 are sequentially arranged in front of the platform 104, the forward and backward reciprocating distances of the second grips 32 are inevitably changed.

Therefore, the forward and backward distances of the X1 axis transfer frame 30 mounted on the X1 axis robot 20 so as to be movable forward and backward may be adjusted.

To this end, the X1-axis feed frame 30 is moved back and forth along the X1-axis on the X1-axis robot 20 by the driver medium 28 that receives power from the X1-axis feed drive means 18, and simultaneously transfers the X1-axis. The elevating rod 43 of the second grip elevating means 40, including the second grip elevating means 40 mounted on the frame 30, is also moved forward and backward, thereby moving forward and backward of the second grip 26. Round trip distance is adjustable.

Thus, the front and rear conveyance distance of the second grip 26 is easily adjusted, so that the insert tip 24 from the meter 102 to the rearmost position of the platform 104 or from the meter 102 to the front position of the platform 104. ) Can be arranged in order.

On the other hand, in order to arrange the insert tip 24 seated on the platform 104 more and more densely as described above, the hypotenuse and hypotenuse of the triangular insert tip is alternately arranged as shown in FIG. It is preferable.

To this end, when the direction change motor 45 mounted on the bottom of the X1 axis feed frame 30 rotates at the same time and the drive gear 46 mounted on the output shaft of the direction change motor 45 also rotates, The rotational power is transmitted to the turning gear 47 mounted on the elevating rod 43 through the timing belt 48, so that the rotational power of the turning gear 47 and the elevating rod 43 is changed in accordance with the turning direction of the turning. The orientation of the two grips 26 is achieved.

Therefore, the insert tip 24 seated on the platform 104 by the second grip 26 can be alternately arranged with the hypotenuse and the hypotenuse, so that more insert tips 24 can be densely stacked.

On the other hand, if the insert tip is repeatedly formed in the press as described above, its surroundings may be contaminated with the metal powder, which is the material of the insert tip, and it may be cleaned periodically so that the molding process of the insert tip may proceed. .

To this end, a cleaning means 50 for cleaning the powder around the press is mounted on the front end side of the X1-axis robot 20.

That is, the spindle motor 51 is mounted on the front end side of the X1-axis robot 20, and the brush support block 53 is mounted on the elevating output shaft 52 of the spindle motor 51 so as to be capable of raising and lowering. The front end of the brush support block 53 is integrally mounted with a brush 54 for cleaning the powder around the press.

Accordingly, the elevating output shaft 52 is lowered based on the operation of the spindle motor 51, and at the same time the brush supporting block 53 connected to the elevating output shaft 52 is also lowered, so that the front end of the brush supporting block 53 is lowered. The brush 54 attached to the part is brought into close contact with the press periphery.

Subsequently, the forward and backward movements of the first and second grips 26 and 32 as described above and the left and right transfer operation of the Z1-axis robot 14 mounted on the Y-axis rail 12 are performed, thereby allowing the brush 54 to be moved. By brushing, powder and contaminants around the press can be easily removed.
