Abstract

PURPOSE:To transfer easily without being restrained for changing and manufacturing of the metallic die by holding products formed by a forging press with a jaw at an end of a sliding rod installed on a carrier capable of travelling front and rear, or right and left, and enabling to make a three dimensional motion so as not to restrict changing and manufacture of the metallic die. CONSTITUTION:A blank is carried into a metallic die 2 between four supports 1 of a press A and it is formed by the press to a form made by the metallic die 2. When the press formed parts are taken out, a main body 6 of a carrier B for transferring is made movable upwards and downwards by a cylinder 9 and also capable to travel towards rear and front on a rail 4 by a cylinder 10, and further capable to travel towards right and left on a rail 5. The carrier B for transferring is provided with a sliding rod 30 capable of travelling towards front and rear, and a jaw 48 for holding a press-formed parts is fitted to the end. By means of the forementioned mechanism, a sliding rod 30 is capable of travelling freely upwards and downwards, right and left, and front and rear, so that the press-formed parts is taken out from the press device by the jaw 48 without being restrained for movement at the time of changing or manufacturing of the metallic die.

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for conveying molded products in a forging press or the like.

BACKGROUND OF THE INVENTION As shown in FIG. 11, a pair of transformer 7 apertures b, b are disposed between four supports 6 of a press, and a feed mechanism 1? , l'', a pair of transformers 7 aper b,
bt - As shown in Fig. 12, clamp operation d, lift operation -, advance operation f, and down operation! It is known that a molded article j is gripped and conveyed between a pair of transformers 7 apertures b and b by performing three-dimensional movements of , unclamping operation, and return operation i, as shown in FIG.

Problems to be Solved by the Invention A pair of elongated transfer bars b and bf must be placed around the mold k in the press, which imposes restrictions on mold exchange and mold manufacturing, and Feeding mechanism C
The cost is high because it requires

Means for Solving Problems and Effects A sliding rod is provided on a carrier that is movable vertically and horizontally on the main body, and a sliding rod is provided on the main body so as to be movable back and forth. The sliding rod and the carrier are connected to a motor provided on the main body to enable three-dimensional movement of the jaws, and the jaws are supported on a cantilever by the main body.

゛ A mold 2 is disposed between four pillars (side frames) 1 of the press A, and a material is carried into the mold 2 by a material carrying device 3.

A pair of rails 4 for forward and backward movement are provided adjacent to the press A, and a pair of rails 5 for left and right movement are provided orthogonally to the rails 4 for forward and backward movement. , 5, the main body 6 of the conveying device B is movable.

The main body 6 is rotatably provided with a wheel 7 for moving forward and backward, and a wheel 8 for moving left and right is rotatably supported on an arm 10 that is vertically swung by a cylinder 9. , the main body 6 is moved back and forth along the back and forth movement rail 4 by the cylinder 11.

The main body 6 has a substantially housing shape, and a lift cam 1 is installed inside the main body 6.
A camshaft 15 to which a clamp cam 13, a feed cam 14, and a feed cam 14 are fixed is rotatably supported horizontally in the left-right direction. Gear 19, drive gear 20, clutch brake 21, flywheel 22, belt 23, pulley 2
4 to the output side of the motor 25, and a pair of left and right lift links 2 in the body 6 are plate-shaped.
The upper and lower parts of the IJ sink 6 are supported so as to be able to swing vertically in parallel via a parallel link mechanism consisting of upper and lower links 271 and 27m, respectively, and between the upper part of the IJ sink 6, a pair of carrier guide rods 2δ are installed. A carrier 29 is installed so as to be movable in the left-right direction along this carrier guide rod 28, and a sliding rod 30 is provided on this carrier 29 to slide in the front-back direction. It is movably provided, and the longitudinal middle of the jaw mounting bar 31 is laterally fixed at the tip of the rasp.

The lift link 26 is provided with a cam 7 follower 32 that comes into contact with the lift cam 12, and the upper link 271 - an action cylinder 33 for the lift cam swings and urges the cam 7 follower 32 to come into contact with the lift cam 12. Along with being there,
A clamp lever 35 that is swing-biased by an action cylinder 34 for use with a clamp cam is provided with a cam 7 and 4 36 that abuts against the clamp cam 13, and this clamp lever 35 is connected to a sliding rod 3° via a rod 37. It is.

Feed lever 39 supported vertically swingably on support shaft 3B
The cam follower 41 is urged to swing by the action cylinder 40 for the feed cam, and the cam follower 41 is in contact with the feed cam 14, and a connecting piece 42 is pivotally attached to the tip by a first pin 43. A second bin 44 that is orthogonal to the first bin 43 is pivotally connected to one end of a lever 45. This lever 45 is swingably supported by a support shaft 46 that is orthogonal to the support shaft 3B, and the other end is connected to a link 47. It is pivotally connected to the carrier 29 via.

The jaw mounting bar 31 is provided with a plurality of jaws 48 that open and close in the longitudinal direction.As shown in FIG. Although this structure is used to grip the molded product 52, it is not limited to this structure.

By rotating the camshaft 15, the clamp lever 35 is swung by the clamp cam 13, as shown in FIG. 6, so that the sliding mud 30 slides back and forth with respect to the carrier 29.

Similarly, as shown in FIG. 7, the lift link 26 is swung vertically by the cam 12 while maintaining parallelism, so that the sliding rod 30 moves up and down together with the carrier 29. Similarly, as shown in FIGS. 8 and 9, the feed cam 14 causes the carrier 29 to slide left and right along the carrier guide rod 2g, and the sliding rod 30 moves left and right.

Since it is like this, the clamp cam 13 and the lift cam 12
, by setting the phase of the feed cam 14, the cam shaft 15
The rotation causes the jaw 48 to perform a three-dimensional movement as shown in FIG.

When performing press working, the main body 6t is moved by the cylinder 11 to position the positioning wedges 53 provided on both sides of the main body 6 in contact with the support 1, and in this state, the motor 25 is driven. The molded products can be sequentially conveyed to the mold 2 by moving the jig M-48 in three dimensions and opening and closing the jig M-48.

In addition, by moving the main body 6 in the opposite direction to the above, aligning the wheels 8 for left and right movement with the rails 5 for left and right movement, and extending the cylinder 9 and swinging the arm 10, the wheels 8 for left and right movement are pushed down, and the wheels 8 for left and right movement are pushed back and forth. The moving wheels 7 can be raised to move the main body 6t in the left-right direction.

Effects of the Invention Since the jaw 4g is in a cantilevered state protruding from the main body 6, there is no restriction on mold replacement work and mold manufacturing even if the molded product is conveyed from the mold by being attached to the press. In addition, since there is no need for two feeding mechanisms unlike the conventional method, the cost is reduced.
