Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a press forming apparatus in the press forming field in which a plurality of rotary tables are arranged.

Conventional technology Traditionally, forged parts are manufactured through multiple processes. Multiple forging presses for a single process are arranged in a line or in an L shape, and the material is transferred to each forging press using a robot or other manufacturer or transfer machine. It was transported to each position and molded.

Problems to be Solved by the Invention For this reason, a manipulator or transfer machine is required between each forging press, and the material must be put into the mold of each forging press and taken out, resulting in a net It took extra time to press the press, which caused productivity to deteriorate.

Therefore, the applicant has developed a device in which a rotary table is installed in a single forging press, and dies for the number of press steps required are placed around the rotary table, allowing forging to be performed with one injection of material. are doing.

Therefore, it has become possible to significantly improve productivity compared to the past.

However, the cost of the equipment is quite high compared to the molded parts, and increasing the production efficiency of the equipment has been a future challenge.

Means for Solving the Problems The present invention has been made in view of the above-mentioned points. A plurality of molds characterized in that a plurality of rotary tables each having a number of molds or mold boulders are arranged, and the materials to be put into the molds or mold holders of each rotary table are press-molded at the same time. The present invention provides a press molding device equipped with a rotary table.

According to the present invention, even if the molded part requires multiple press steps, the material only needs to be input once, and the extra time can be reduced as much as possible by using the rotary table installed in the press molding device. .

By arranging multiple rotary tables in a press forming machine and performing press forming on each at the same time, one press forming machine can be used effectively, and productivity can be improved in proportion to the number of rotary tables. can.

Example Hereinafter, the present invention will be explained based on examples.

FIGS. 1 and 2 show an embodiment of a forged product press according to the present invention. The press forming device l of the forging press is the first
As shown in the figure, a rotary table 4 is rotatably disposed between a press slide 2 and a bed 3. As shown in FIG. 2, two rotary tables 4 are arranged symmetrically with respect to the center line of the press molding apparatus 1, and the molds 5 for the required number of press steps are uniformly arranged around the rotary table 4. They are arranged radially on each pitch.

Below this rotary table 4 is a bed 3 as shown in Fig. 1.
A lower guide plate 6 is installed in each section, and an upper guide plate 8 is installed on the upper side of the rotary table 4, with a required punch section 7 protruding from the press slide 2 section, facing the mold 5 described above. . As shown in FIG. 2, material input and molded product take-out sections 9 are provided on the sides of the rotary table 4 on both sides of the press molding apparatus 1, and the material 10 is supplied from the material input and molded product take-out sections 9 on both sides. Molded products 11 are charged into a mold 5 on a rotary table 4 and press-molded in a material input and molded product removal section 9, and are pushed up by a knockout bin (not shown) so that they can be taken out from the mold 5.

Incidentally, the press slide 2 of the press forming apparatus 1 can be driven up and down by a known forging means, and the rotary table 4 can be driven to rotate by using an index table or by turning with a servo motor or the like. .

Therefore, by simply charging each material once into the rotary table from the side of the press-forming device of one forging press, the rotary table sequentially rotates one pinch at a time, and the materials are sequentially pressed and formed into two pieces at a time. Therefore, productivity can be doubled with one device.

In the above embodiment, since the rotary tables are arranged symmetrically in the press molding device, it is suitable for molding a pair of symmetrical molded products, and the eccentric load applied to the press can be kept as small as possible. Although this is preferred, it goes without saying that the same product or different products may be molded.

Other examples FIG. 3 shows another embodiment of the invention.

In this embodiment, as shown in the figure, four rotary tables 4 are arranged in a press forming apparatus 1 in a line-symmetrical or axially symmetrical manner.

In this way, a plurality of rotary tables can be provided as needed to perform press molding as appropriate.

In the above embodiments, the mold was arranged on a rotary table, material was put in, and the molded product was taken out. It is also possible to put the whole mold into the mold holder and take it out together with the mold.

Although a forging press has been described as a press forming apparatus, the present invention is also applicable to other presses that require multiple steps.

Effects of the Invention As described above, in the present invention, press forming can be performed with high work efficiency using a rotary table, and 1.
It is possible to simultaneously press and mold materials fed to a plurality of rotary tables using a single press molding device, thereby increasing productivity by several times and enabling mass production with high investment efficiency.
