Description
Technical field
The present invention relates to neodymium iron boron strip-shaped product manufacturing technology field, specifically it is a kind of it is simple in structure, process is simple,
The high neodymium iron boron strip-shaped product mould of production efficiency and application method.
Background technology
It is well known that neodymium iron boron is briefly a kind of magnet, and the magnet that we usually see is the difference is that its is excellent
Different magnetic property and be referred to as " magnetic king ", substantial amounts of rear earth element nd, iron and boron are contained in neodymium iron boron, its characteristic is hard and crisp, by
In surface easily by oxidation corrosion, neodymium iron boron must carry out surface coated treatment, and surface chemistry passivation is good solution method
One of, neodymium iron boron has high magnetic energy product and coercivity as a kind of of rare earth permanent-magnetic material, while high-energy-density is excellent
Point makes Nd-Fe-B permanent magnet material be applied widely in modern industry and electronic technology, so that instrument and meter, electroacoustic are electric
Miniaturization, lightweight, the slimming of the equipment such as machine, magnetic separation magnetization are possibly realized.The advantages of neodymium iron boron is cost-effective, and tool is good
Mechanical property.
At present, it is typically all first due to the particular/special requirement of strip product during neodymium iron boron small pieces formed product
Compressing bulk neodymium iron boron product, is then cut into sheet and is cut into bar shaped again, finally cut into pieces again, its general process is：
Compressing big bulk product is put into stove first and is sintered, the chunk products for sintering completion then are carried out corase grinding takes
To size, then sticky stick carries out cutting sheet, then tests to big flake products, and examining the product of qualification, to carry out mill again large stretch of,
Test again after mill is large stretch of, qualified product carries out boiling material, and then sticky stick carries out slitting processing again, and strip-shaped product is carried out
Examine, carry out fine grinding size again after the assay was approved, mill arc is carried out after the completion of fine grinding, is tested after the completion of mill arc, it is qualified to examine
Product cut small pieces with sticky stick again and handle, the small pieces cut are ground again, carry out boiling material again after grinding, material feeding is complete
Test after, examine the product of qualification to carry out chamfering, the process of plating again, final inspection, final inspection are realized after the completion of electroplating work procedure
After the completion of packed again and delivery processing, and then complete the manufacturing procedure of whole strip product, in the process, by
Become small flake products by cutting in the neodymium iron boron product by bulk, the process of final inspection, which have passed through, cuts large stretch of and slitting process, often
Product will be examined by a cutting action, eliminating for substandard product is thus caused, also results in the waste of material,
Simultaneously as the increase of the process of cutting, causes the cutting accuracy of integrated product to improve, once a sheet or rod-shaped objects
Cutting shift, may result in follow-up cutting can all produce error, and therefore, the error of cutting can cause the wave of bigger
Take, therefore, the increase of process can cause the increase of substandard product amount, now, some enterprises in order to reduce the waste rate of product,
Practical mold design is the die cavity of the hexagonal prism-shaped in section, and the triangle on both sides is cut i.e. after so producing product
Rod-shaped objects can be formed, this process reduces the process for cutting sheet, but since the cutting of the triangular prism on both sides also results in wave
Take, therefore, it is impossible to realize the reduction of the simple and waste rate of process.
The content of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, there is provided one kind is simple in structure, process is simple, production effect
The high neodymium iron boron strip-shaped product mould of rate and application method.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of neodymium iron boron strip-shaped product mould, the mould is by magnetic conduction front side board, not magnetic conduction back side panel, magnetic conduction left plate, no

Produce the flow detail of product, the process time of 720 flake products of processing contrasts as shown in Table 1：
As apparent from the table, the flow process between square blank production product and bar shaped blank production product contrasts,
Bar shaped blank production product has saved ten step process flows, saves the process examined three times, thus there is no unqualified production
Product are eliminated, and then increase qualification rate, reduce waste, while as can be seen from the table, process same amount of product side
The process time of block will save almost half time, therefore produce this apparently higher than the process time of rod-shaped objects
The mould of shape product has obvious effect,
Moreover, the present invention due in the knockout course after compressing not in accordance with front side board 1, back side panel 2, left plate 3,
The order of right plate 4 is demoulded, but first removes front side board 1 and back side panel 2, then cope plate 5 and left plate 3, right side
Plate 4 removes together under the action of upper handle 10, the swallow-tail form of left plate 3, the lower section of right plate 4 along 6 both sides of lower template
Boss 8 moves upward out, and can prevent moving left and right and rock to compressing product generation damage, Ke Yishun for cope plate 5
Profit is demoulded compressing product, and the not magnetic conduction left plate 3 and the not inner side on magnetic conduction right plate 4 are set pair respectively
Being respectively arranged on the left side and the right side for the dove-tail form boss 8 of title, the cope plate 5 and lower template 6 is matched with dove-tail form boss 8
Dove-tail form slideway 9, ensures to prevent cope plate 5 and the movement of lower template 6 from causing compressing product loose during form removal
To destroy, the top of the cope plate 5 is equipped with upper handle 10, and upper 10 upper end of handle is set to the plane for facilitating press to suppress,
Connecting plate 11 is respectively equipped with the cope plate 5 of the upper left and right sides of handle 10, one end of connecting plate 11 is connected with cope plate 5,
Other end stretching is simultaneously concordant with the upper face of left plate 3 or right plate 4, and the connecting plate 11 of extension is equipped with connecting hole 12,
The upper surface of corresponding with connecting hole 12 left plate 3 or right plate 4 is equipped with connecting pole 13, and the cylinder of connecting pole 13 is equipped with elasticity
Connecting plate 11 is closely connected by clamping ring 14, elastic connection circle 14 with connecting pole 13, and handle 10 is in the upper process carried in convenience
In above carried together with left plate 3 and right plate 4, prevent that left plate 3 and right plate 4 come off during carrying, and cause damages, together
When connecting plate ensure that press serrated tip of the lower groove and upper groove of cope plate 5 and lower template 6 during pushing connects
Touch without extruding, will not produce damage while ensure that pressing result to mould, the elastic connection circle 14 be with
The section of transition radian is connected in massif arc with connecting pole, prevents the pushing of connecting plate 11 from being caused brokenly to elastic connection circle 14
It is bad, and then cope plate 5 is protected, have the advantages that simple in structure, process is simple, production efficiency is high.
