Technical field
The utility model relates to neodymium iron boron and is produced into mould technical field, particularly a kind of neodymium-iron-boron die with novel upper and lower stamping fixed structure.
Background technology
Nd-Fe-B permanent magnet is the energy-storing device that a kind of energy density is very high, utilizes it can realize expeditiously the mutual conversion of energy and information, is one of important substance basis promoting modern technologies and social progress.Product is widely used in the aspects such as computer hard disc driver, motor and human body NMR.Make that the operation of Nd-Fe-B permanent magnet comprises that batching, melting, hydrogen are broken, powder process, batch mixing, moulding, sintering, timeliness, machined, surface treatment etc., product specification has diversified feature.In process of production, the product needed of different size is carried out moulding with different moulds, therefore needs frequently to change types of molds.Granted patent CN203109227U, CN201755657U mold and punching head and extension bar all adopt dovetail connected mode, and along with drift and extension bar are frequently changed, connection reliability between the two can be worse and worse.Undershoot is connected with undershoot connecting rod by dovetail, and undershoot connecting rod fixes by undershoot connecting rod fixture; Being punched in so down relative position in former fixes; Undershoot easily produces and former scraping, pulls former; Cause formed product difficulty.
Therefore, need to carry out certain improvement to undershoot fixed structure on neodymium-iron-boron die, to enhance productivity and reliability.
Utility model content
Technical problem to be solved in the utility model is, a kind of neodymium-iron-boron die with novel upper and lower stamping fixed structure is provided, and can improve the connection reliability of upper punch and connecting rod, avoids undershoot to pull former, enhances productivity and die life.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of neodymium-iron-boron die with novel upper and lower stamping fixed structure, comprise upper punch connecting rod, fixed screw, upper punch, former, undershoot, undershoot connecting rod, undershoot connecting rod fixture, turnbuckle, pressing plate, contour post, screw and mould bases, wherein, former passes through pressing plate, contour post and screw are fixed on mould bases, upper punch is connected with upper punch connecting rod dovetail, the dovetail groove rear end of upper punch connecting rod has clearance groove, clearance groove vertical direction is provided with fixed screw, undershoot is connected with undershoot connecting rod dovetail, undershoot connecting rod is fixedly connected with undershoot connecting rod fixture, undershoot connecting rod fixture base plate is provided with through hole, turnbuckle is housed in through hole, turnbuckle upper overturning bottom surface and fixture plate upper surface are provided with gap.
Further improvement of the utility model is that the gap groove width of the dovetail groove rear end of upper punch connecting rod is 0.5mm.
Further improvement of the utility model is that the gap of turnbuckle upper overturning bottom surface and fixture plate upper surface is 0.25-0.35mm.
The beneficial effects of the utility model are that it is firm, reliable, quick that upper punch is installed; Undershoot can be movable, can automatically regulate the gap of drift and former.Saved the time in manual adjustment gap; Greatly improve dress mould speed.Meanwhile, in compressing process, undershoot regulates the gap with former automatically, has avoided former to pull, and has increased the life-span of mould.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of neodymium-iron-boron die with novel upper and lower stamping fixed structure of the utility model.
Contour post 11 screw 12 mould bases of 1 upper punch connecting rod 2 fixed screw 3 upper punch 4 former 5 undershoot 6 undershoot connecting rod 7 undershoot connecting rod fixture 8 turnbuckle 9 pressing plate 10.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further set forth the utility model.
Referring to Fig. 1, a kind of neodymium-iron-boron die with novel upper and lower stamping fixed structure comprises upper punch connecting rod 1, fixed screw 2, upper punch 3, former 4, undershoot 5, undershoot connecting rod 6, undershoot connecting rod fixture 7, turnbuckle 8, pressing plate 9, contour post 10, screw 11, mould bases 12; Former 4 is fixed on mould bases 12 by pressing plate 9, contour post 10 and screw 11, upper punch 3 is connected with upper punch connecting rod 1 dovetail, the dovetail groove rear end of upper punch connecting rod 1 has clearance groove, clearance groove vertical direction is provided with fixed screw 2, undershoot 5 is connected with undershoot connecting rod 6 dovetails, and undershoot connecting rod 6 is fixedly connected with undershoot connecting rod fixture 7, and undershoot connecting rod fixture base plate is provided with through hole, turnbuckle is housed in through hole, and turnbuckle upper overturning bottom surface and fixture plate upper surface are provided with free gap.
Upper punch connecting rod 1 dovetail rear end has the groove of elongated bar 0.5mm, and the degree of depth of clearance groove is 25-35mm.Undershoot connecting rod fixture 7 is pushed down by turnbuckle 8, and the gap of turnbuckle 8 upper overturning bottom surfaces and fixture plate upper surface is 0.25-0.35mm.
