A seating plate 33 positioned at the end of the material supply track 3 and heated to a set temperature, and a material input means for introducing the material into the lower mold while horizontally moving along the upper portion of the seating plate; It is composed of a drive means for horizontally moving the material input means.

In one embodiment of the present invention, the material inserting means is provided with a slider 35 mounted on the base 34 so as to be movable horizontally, a guide rod 36 and a guide for guiding the horizontal movement of the slider. A block 37, a pair of fingers 39 formed with a cam groove 38 which is hinged to one end of the slider tip and symmetrical to each other, and a cam pin 40 fitted in the cam groove 38 fixed to the seating plate. It consists of.

However, it is not necessarily limited thereto.

The reason for this is as shown in Fig. 7 shown in another embodiment, a lever which is rotatably installed on one side of the seating plate 33 around the pin 41 to inject the material 1 placed on the seating plate into the lower mold 6. This is because the raw material 1 can be introduced into the lower mold 6 by rotating in the state where the raw material 1 is positioned in the guide groove 43 of the lever 42.

The driving means of the material input part 7 is fixed to the press ram 45 to which the upper mold 44 is fixed by the fixing piece 46 so that one end of the slider 35 is connected, and the horizontal surface 47a and the inclined surface 47b. The first cam plate 47 and the fixed plate 48 fixed to the base 34 and the slider 35 is formed between the elastic member 49 to restore the slider.

At this time, when the bearing 50 connected to the first cam plate 47 is rotatably installed at one end of the slider 35, the phenomenon that the portion connected to the first cam plate 47 is worn can be significantly reduced.

Moreover, the 1st cam plate 47 is attached to the fixing piece 46 so that the angle adjustment is possible by the adjustment screw 51. As shown in FIG.

This is to adjust the stroke of the slider 35 by adjusting the position of the first cam plate 47 as shown in FIG.

The molding part 8 is formed by punching the lower mold 6 into which the heated material 1 is injected, and the material injected into the lower mold as shown in FIGS. 10 (a) and 10 (b). At the same time, the upper mold 44 separates the molded product from the lower mold 6.

As shown in FIGS. 11 to 13 (b), the ejection portion 9 is formed with a hole 52 through which the upper mold 44 passes, and the ejection plate 53 provided in proximity to the upper side of the lower mold 6. ), A dispensing means which is rotatably installed on one side of the dispensing plate so that the product 54 is separated from the upper mold 44 and blows out to the outside, and the driving means rotates the dispensing means within a predetermined angle range. It consists of.

The ejection plate 53 installed close to the upper side of the lower mold 6 is fitted to a pair of adjustment screws 55 fixed to the base 34 and then tightened with the nut 56 coupled to the upper and lower portions of the ejection plate. The height of the blowout plate 53 is adjusted by this.

It is composed of a shooter 59 coupled to the bar so as to be idling hitting the product is separated from the upper mold (44).

A shooter 59 is rotatably installed at the ejection bar 58, and a limit switch 60 is installed at the other end of the shooter to detect the rotation of the shooter and control the operation of the device.

The reason is that the limit switch 60 detects this if the shooter 59 does not hit the product 54 separated from the upper mold 44 and suspends the operation of the device so that a safety accident does not occur.

The drive means is fixed to the press ram 45, the second cam plate 61 is formed with a horizontal surface (61a) and the inclined surface (61b), and the arm (62) fixed to the support bar (57) and connected to the second cam plate; It is composed of an elastic member 64 connected between the arm and the support bar (63).

At this time, a bearing 65 connected to the second cam plate 61 is rotatably provided at the end of the arm 62.

This is to prevent the phenomenon that the portion connected to the second cam plate 61 is worn out.

On one side of the dispensing means, a discharging track 66 for discharging the product is installed.

In addition, the guider 67 is fixed to the upper portion of the blowout plate 53, and a gas discharge pipe 68 for discharging the gas generated when the product is molded to the outside is provided at one side of the guider.

Referring to the operation of the present invention configured as described above is as follows.

First, the raw material 1 cut | disconnected to predetermined length in the hopper 1 and the bowl 10 is filled, and it demonstrates from the state in which the press ram 45 is located in bottom dead center.

In this state, the bearing 50 provided on the slider 35 is connected to the horizontal surface 47a of the first cam plate 47 so that the slider is transferred to the left side in the drawing by the restoring force of the elastic member 49. The bearing 65 provided on the arm 62 is connected to the inclined surface 61b of the second cam plate 61, and the shooter 59 counterclockwise around the support rod 57 while tensioning the elastic member 64. It is still rotated as far as it can go.

The reason why the initial press ram 45 is located at the bottom dead center is described for convenience so that the process of injecting the material 1 transferred along the material supply track 3 into the lower mold 6 can be described in order. It is to.

Therefore, when power is applied to the device by operating the control unit 69, 70, the bowl 10 is driven and power is also supplied to the heater 17 of the material heating unit (high frequency heater) 4, thereby heating the material. The negative heater 17 is heated so that the raw material 1 can be raised to a temperature suitable for molding.

Then, when the material 1 in the bowl 10 is moved in the direction of the arrow shown in FIG. 2 by vibration and sequentially supplied along the material supply track 3, the material supply track connected to the outlet side of the bowl is inclined downward. Therefore, the heavy chain material 1 is transported downward along the material supply track by its own weight.

When the material 1 is transported along the material supply track 3 as described above, a detection means 14 such as an infrared detector installed on the inlet side of the material supply track detects the transport of the material 1. If it is detected, the device operates normally and if there is no material jam or material to be supplied, and the material is not detected, the operation of the device is suspended, and the operator is notified by means of a buzzer or a lamp to take emergency measures.

Meanwhile, when the material supply in the bowl is completed by the continuous operation of the bowl 10, the limit switch 13 installed in the bowl 10 does not detect the movement of the material 1, so that the shutter is installed on the outlet of the hopper 12. (11) is opened so that the material (1) in the hopper 12 is automatically introduced into the bowl (10).

However, even if the material 1 in the hopper 12 is completely introduced into the bowl 10 and the shutter 11 is opened, the material 1 in the bowl is not supplied to the material supply track 3, that is, the limit switch ( If 13 does not detect the material 1 in the bowl 10 and the set time elapses, but does not detect the material 1, it is determined that there is no material to be supplied to the bowl 10 in the hopper 12 and the operation of the device. Suspend and inform the worker when the input of the material by a separate notification means.

When the material 1 is supplied along the material supply track 3 by the above-described operation, the material 1 is heated to a temperature suitable for forging while passing through the material heating part 4.

When the raw material 1 is heated by the heater 17 while passing through the inside of the raw material heating part, the raw material is guided by a plurality of raw material conveying guide rods 19 installed in the conveying direction of the raw material on the inner circumferential surface of the heater 17. The frictional force is minimized and is transferred. At this time, the material transfer guide rod 19 is made of a ceramic material so that wear is prevented even if used for a long time to induce smooth transfer of the material 1.

The material 1 heated to an appropriate temperature suitable for molding while passing through the material heating part 4 is continuously transported downward along the material supply track 3, at this time, the material separation supply part installed at the rear end of the material heating part. The material separation supply piece 23 in (5) maintains the state as shown in FIG. 4, so that the heated material 1 is caught by the control surface 22 through the injection hole 20, so that the feeding is controlled.

When the heating of the heated material 1 is controlled by the material separation supply piece 23, the first cylinder 25 is driven to match the discharge hole 21 with the material supply track 3 so as to control the surface 22. Is supplied to the material input part side in the direction of the arrow.

However, if the material 1 is heated to a temperature lower than the set temperature and is supplied to the molding part 8, the mold may be damaged when the material is molded. Therefore, the defective material 1a that is not heated to the temperature set before being supplied to the molding part is supplied. ) Is preferably selected and taken out.

That is, as shown in FIG. 4, the temperature sensor 27 installed above the outlet of the material heating part 4 adjusts the temperature of the material 1 which is transferred to the material separation supply part 5 along the material supply track 3. If it is determined that the material is heated to a temperature suitable for molding, the material 1 heated by matching the delivery rail 28 of the movable track 30 to the material supply track 3 as shown in FIG. It is supplied to the input part 7 side.

However, if it is determined that the heating is lower than the set temperature of the heated material 1, the second cylinder 31 is driven to advance the movable track 30, as shown in Figure 5 (b) The take-out rail 29 coincides with the supply track 3, whereby the defective material 1a, which is separated and conveyed by the material separation supply part 5, is taken out to the upper pipe 32 along the take-out rail 29. It will be contained in a separate collection bin (not shown).

The movable track 30 moves forward and backward by the second cylinder 31 as the temperature sensor 27 measures and determines the temperature of the heated material 1.

The material (material heated at a temperature suitable for molding) determined as a good product by the operation as described above is transferred along the delivery rail 28 coinciding with the material supply track 3 to be mounted on the seating plate 33. Once loaded, the material 1 placed on the seating plate must be molded into the lower mold 6 and simultaneously molded.

To this end, when the press ram 45 rises, as shown in FIGS. 6 and 8, the bearing 50 connected to the horizontal surface 47a of the first cam plate 47 is connected to the inclined surface 47b and gradually. Since the slider 35 is pushed by the elastic member 49, the slider 35 is moved to the lower mold 6 side like the one-dot chain line.

Accordingly, the finger 39, one end of which is hinged to the slider 35, is also advanced toward the lower mold 6. At this time, a cam groove 38 is formed in the finger 39, and a seating plate is formed inside the cam groove. Since the cam pin 40 fixed to 33 is inserted, the finger 39 moves toward both sides of the lower mold 6, and is opened to both sides like a dashed line, and when the maximum advance point is reached, the inner side is formed by the shape of the cam groove 38. While holding back the material 1 placed on the seating plate 33, it is put into the lower mold 6.

The feed amount of the slider 35 can be adjusted by loosening or tightening the adjusting screw 51 as shown in FIG. 9 by finely rotating the first cam plate 61 as a single dashed line.

On the other hand, in FIG. 7 shown in another embodiment, as the press ram 45 rises, the lever 42 rotates around the pin 41, so that the material 1 placed on the seating plate 33 is guide groove. Guided by (43) is put into the lower mold (6).

As the press ram 45 rises, the slider 35 is advanced while the elastic member 49 is tensioned, and the heated material 1 is inserted into the lower mold 6 by the finger 39. 2 Since the bearing 65 connected to the inclined surface 61b of the cam plate 61 is connected to the horizontal surface 61a, the shooter 59 that has been rotated counterclockwise around the supporting rod 57 is formed of the elastic member 64. It is reduced to the initial state by the restoring force.

In the above-described operation, the press ram 45 which is located at the top dead center in the state in which the material 1 heated to the temperature suitable for molding in the material heating part 4 is introduced into the lower mold 6 by the material input part is On the contrary, since the bearing 50 connected to the inclined surface 47b of the first cam plate 47 is connected to the horizontal surface 47a, the slider 35 is moved by the restoring force of the elastic member 49. Since the bearing 65, which is moved to the left side and is reduced to the initial state and connected to the horizontal surface 61a of the second cam plate 61, is connected to the inclined surface 61b, as shown in solid lines in FIGS. 11 and 12 The take-out bar 58 and the shooter 59 rotate in the counterclockwise direction about the support bar 57 while tensioning the elastic member 64, and are positioned at the same point as the dashed line.

In the operation as described above, the upper mold 44 located at the top dead center as shown in FIG. 10 (a) descends to the bottom dead center as a dashed line, and punches the material 1 injected into the lower mold 6 at an appropriate temperature. The heated material 1 is molded into the product 54 by the upper mold 44 and the lower mold 6.

Gas generated when the material is molded by the operation as described above is forcibly discharged to the outside through the gas discharge pipe (68).

The product 54 thus formed is press-fitted into the upper mold 44 and separated from the lower mold 6 together with the upper mold at the time of raising the press ram 45 as shown in FIG. 10 (b).

That is, when the molded product 54 is raised in the press-fitted state in the upper mold 44, the upper side of the lower mold 6 is formed larger than the outer peripheral surface of the upper mold 44, the hole 52 smaller than the outer peripheral surface of the product is formed The upper die 44 passes through the hole 52, but the product 54 does not pass through the hole and hits the ejection plate 53, so the product 54 is separated from the upper die 44.

As described above, when the product is separated from the upper die 44 due to the rise of the press ream 45, the bearing 65 coupled to the arm 62 is connected to the horizontal surface 61a of the second cam plate 61. Since the take-out bar 58 and the shooter 59 are rotated clockwise in the initial state by the restoring force of the elastic member 64, the shooter 59 hits the product separated from the upper mold 44, and thus the delivery track 66. It is taken out to the side.

If the shooter 59 hits the product at the time when the product is completely separated from the upper mold 44 in the above operation, the shooter 59 coupled to the take-out bar 58 idlingly does not rotate, and thus the thirteenth (a) As the limit switch 60 does not operate as described above, the device operates normally.

However, if the shooter 59 does not hit the product separated from the upper mold 44 correctly and the load is applied, the shooter 59 rotates to operate the limit switch 60 as shown in FIG. 13 (b). The operation of is stopped automatically.

That is, if the product is not discharged to the discharge track 66 side, the product is located in the lower mold 6, or if the operation is continued in the state of being located in other parts, it is to prevent the accident because it involves a risk of safety accidents .

As described above, the present invention selects only the material heated at a temperature suitable for molding in the material heating part and automatically puts it into the lower mold, and at the same time, automatically ejects the product from the lower mold to the outside of the device while being pressed into the upper mold. Therefore, it becomes possible to fully realize the automation of the device. Accordingly, it is possible to mass-produce the nut for the water pipe connection while reducing the labor cost, thereby reducing the production cost and distributing it at a lower price.

In addition, since the input of the material into the molding part is made automatically, it is also possible to prevent the occurrence of a safety accident due to the carelessness of the operator.
