Background

At present, in small and medium-sized enterprises in powder metallurgy in China, a traditional press is an important tool for the enterprises to produce products, is a forming device for the powder metallurgy products, and plays a key role in the process of the powder metallurgy. In the existing small and medium-sized enterprises in powder metallurgy in China, because of the limitation of equipment price cost and product quality requirements, a foreign high-precision servo press with price more than one million yuan cannot be used, and the traditional powder metallurgy press produced by Tianjin and Nantong forging and pressing machine factories and Yangzhou press factories, which are made in China, is generally used; the press has the advantages of low price and durability, but has the defects of low efficiency, difficult realization of automatic batch production and higher cost due to the use of the traditional one-way pressure structure; the utility model aims at providing a fashioned semi-automatic die carrier is used to traditional powder metallurgy press to overcome prior art and can't realize raising the efficiency through the semi-automatic production of powder metallurgy product forming process batch production's way, reach reduce cost's purpose.

SUMMERY OF THE UTILITY MODEL

In order to improve semi-automatic powder metallurgy work efficiency, improve the efficiency of powder metallurgy manual production, reduction in production cost, the utility model provides a semi-automatic die carrier of powder metallurgy press through arranging the bed die structure in a flexible way, reaches the effect that moulding-die, drawing of patterns operation are more convenient nimble.

The utility model provides a technical scheme that its technical problem adopted is: a semi-automatic die carrier for powder metallurgy press is composed of upper punch, female die, lower punch and demoulding unit.

The upper punch is positioned above and fixed on a pressure column of the press; a female die is arranged below the upper punch and provided with a die cavity; a lower punch is arranged below the female die; the demolding device is arranged in contact with the female mold.

The lower punch is also provided with a fixed lower punch plate which is positioned below the lower punch and bears the lower punch; the fixed lower punch plate is used for being fixed on the machine body.

The female die is also provided with a sliding rod which is specifically positioned below the female die; preferably, there are two sliding rods; one end of the sliding rod is connected with the female die, and the other end of the sliding rod is connected with the stop bottom plate; the sliding rod passes through the reserved hole position on the fixed lower punch plate.

The demolding device comprises a screw and a rotating handle, the rotating handle can rotate on the screw, and the position of the female die is adjusted through the lifting of the rotating handle; specifically, the screw may be connected with the stop bottom plate by means of a screw.

Preferably there is a core rod mounted to the stop bottom plate, the core rod passing through the lower punch and extending to the location of the cavity of the female die; in particular, the mandrel can be connected to the stop base by means of a screw connection.

The beneficial effects of the utility model are that, through improving bed die structure and shedder, realize the nimble of bed die structure and arrange, make its operation of being convenient for carry out moulding-die and drawing of patterns, overall structure is simple, also is convenient for maintain, to the product of different models, as long as change take off drift and bed die, just can realize the rapid prototyping of different model products, improve powder metallurgy's semi-automatic operating efficiency to manufacturing cost has effectively been reduced.

Detailed Description

A semi-automatic die carrier of a powder metallurgy press comprises an upper punch 1, a female die 2, a lower punch 3 and a demoulding device 4.

The upper punch 1 is positioned above and fixed on a pressure column of the press; a female die 2 is arranged below the upper punch 1, and a die cavity 21 is arranged on the female die 2; a lower punch 3 is arranged below the female die 2; the demolding device 4 is arranged in contact with the female mold 2.

The lower punch 3 is also provided with a fixed lower punch plate 31 which is positioned below the lower punch 3 and bears the lower punch; the fixed lower punch plate 31 is intended to be fixed to the machine body.

The female die 2 is also provided with two sliding rods 22 which are positioned below the female die 2; one end of the sliding rod 22 is connected with the female die 2, and the other end is connected with a stop bottom plate 23; the slide rod 22 passes through a reserved hole on the fixed lower punch plate 31.

The demolding device 4 comprises a screw rod 41 and a rotating handle 42, wherein the rotating handle 42 can rotate on the screw rod 41, and the position of the female die 2 is adjusted by lifting and lowering the rotating handle 41; the screw rod 41 is connected with the stop bottom plate 23 in a threaded manner.

There is a core rod 5, the core rod 5 is mounted on the stop bottom plate 23, the core rod 5 passes the lower punch 3 and extends to the position of the die cavity 21 of the female die 2; the mandrel 5 is connected to the stop base plate 23 by means of a screw connection.

The product forming process is divided into three stages of powder filling, pressing and demoulding. When powder is filled, the mixture on the charging tray is only required to be scraped into the die cavity 21 in parallel by a scraping blade, so that the powder is ensured to be filled in the die cavity 21; during pressing, after the action program of the press is started, the upper punch 1 presses downwards, and the powder is pressed and formed; during demoulding, the female die 2 is driven to move only by the manual demoulding device 4, so that a product is exposed, and the press forming is completed. For products of different models, the rapid forming of the products of different models can be realized only by replacing the upper punch, the lower punch and the female die.

The above-mentioned embodiment is the utility model discloses a better realization form, should not be understood as the absolute limit of the utility model. Those skilled in the art should also realize that such implementation of the present invention can be achieved without departing from the basic concept and structure of the present invention, and other specific measures are not necessarily taken to be considered as within the scope of the present invention.
