Abstract
The utility model relates to a tombarthite permanent-magnet molding hydraulic machine which comprises a rack, an upper beam, a lower beam, an upper cylinder, a lower cylinder, an upper sliding block and a lower sliding block, wherein the upper and the lower beams are arranged on the rack; the upper and the lower cylinders are respectively arranged on the upper and the lower beams; and the upper and the lower sliding blocks are respectively connected with the upper and the lower cylinders. The hydraulic machine is characterized in that an upper pressure head is fixed on the upper sliding block; an orientation electromagnet is mounted on the lower sliding block, and a female die is arranged between magnetizing poles of the orientation electromagnet; and a lower pressure head is fixed on the lower beam. The hydraulic machine has the advantages as follows: both the orientation electromagnet and the female die are fixedly connected with the lower sliding block, when the upper pressure head downwardly presses power in the female die under the action of the upper cylinder, the lower sliding block is driven by the lower cylinder, and the lower sliding block drives the orientation electromagnet and the female die to move downwards, therefore, the function of two-way pressing of the upper and the lower pressure heads for the power in the female die is fulfilled, the density of pressed products is even and the product quality is improved.
Description
Technical field
The utility model relates to a kind of hydraulic press, particularly a kind of rare earth permanent magnet forming hydraulic press.
Background technology
The rare earth permanent magnet forming hydraulic press is used for rare earth material is pressed into pie, and the upper and lower pressure head of traditional rare earth permanent magnet forming hydraulic press all directly is fixed on the upper and lower slide block that is connected with hydraulic jack.During compacting, seaming chuck and the push-down head that is positioned at former be move toward one another simultaneously, and the rare earth material in the former is suppressed.The product height control of its compacting is difficulty, protects the knockout press instability in addition, and the high density job efficiency is low.
The utility model content
The technical problems to be solved in the utility model provides a kind of rare earth permanent magnet forming hydraulic press, and it can realize bed die floating in pressing process, makes that the product density of compacting is even.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of rare earth permanent magnet forming hydraulic press, comprise frame, be located at the upper and lower crossbeam on the frame, be installed in upper cylinder half and following cylinder on the upper and lower crossbeam, and the upper and lower slide block that is connected with upper and lower cylinder; Its innovative point is: described seaming chuck is fixed on the top shoe; Oriented electromagnetic iron is housed on the described sliding block, and described oriented electromagnetic iron magnetizes former is housed between the cartridge; Described push-down head is fixed on the sill.
Further, be provided with guide rail between four of described upper and lower slide block jiaos and the frame.
Advantage of the present utility model is: oriented electromagnetic iron is all fixedlyed connected with sliding block with former, when seaming chuck under the upper cylinder half effect in pressing down former during powder, following cylinder drives sliding block, sliding block drive oriented electromagnetic iron and former are descending, thereby realize that upper and lower pressure head is to the unsteady two-way pressing function of powder in the former, the product density that feasible compacting is come out is even, and product quality is improved.
Description of drawings
Fig. 1 is the structural representation of rare earth permanent magnet forming hydraulic press of the present utility model.
Fig. 2 is along the cutaway view of A-A line among Fig. 1.
Fig. 3 is along the cutaway view of B-B line among Fig. 1.
The specific embodiment
As shown in Figure 1, comprise frame 1, entablature 2, sill 3, upper cylinder half 4, following cylinder 5, top shoe 6, sliding block 7, seaming chuck 9, push-down head 10, the cartridge 8 that magnetizes, oriented electromagnetic iron 15.
The top and the bottom of above-mentioned frame 1 are provided with entablature 2 and sill 3, and upper cylinder half 4 is housed on the entablature 2, and the pistons end of this upper cylinder half 4 is connected with top shoe 6, and the lower surface of top shoe 6 is fixed with seaming chuck 9.Inverted down cylinder 5 is installed on the sill 3, and it connects with sliding block 7 on the sill 3 by connecting plate and guide pillar.Oriented electromagnetic iron 15 is housed on the sliding block 7, the cartridge 8 that magnetizes of two symmetries is housed on the oriented electromagnetic iron, former 11 is located at two and magnetizes between the cartridge 8, and compresses by the hold-down bolt 12 of cartridge 8 sides of magnetizing.Push-down head 10 is fixed on the sill 3, and it is upward through sliding block 7 and extends in the former 11.
During compacting, push-down head 10 maintains static, seaming chuck 9 is suppressed the rare earth powder in the former 11 downwards under the effect of upper cylinder half 4, when seaming chuck 9 touches rare earth powder, following cylinder 5 drives sliding block 7, and sliding block 7 drive oriented electromagnetic iron 15 and former are descending, thereby realizes the compression moulding of powder in 9,10 pairs of formers of upper and lower pressure head, make that the product density that suppresses is even, steady quality.In pressing process, the rare earth powders in the former 11 are positioned at two centers of magnetizing cartridge 8 all the time, do not influence it and magnetize.
For preventing that upper and lower pressure head 9,10 is offset damage former 11 in pressing process, between four jiaos of upper and lower slide block 6,7 and frame 1, be provided with guide rail.Shown in Fig. 2,3, its concrete structure is: four jiaos of frame 1 are equipped with the inside guide rail in inclined-plane 13, simultaneously, four angles of upper and lower slide block 6,7 also are provided with corresponding guide rail 14, and like this, upper and lower slide block 6,7 is in moving process, can the offset direction, the service life of having improved former 11.
