Abstract
The utility model relates to a bonding rare earth permanent magnet thin-wall part molding die carrier, which comprises an upper template, a female template, a fixing plate and a lower template arranged in sequence from top to bottom, wherein the female template is connected with the lower template through a pull rod; and the lower template is driven by using a jacking cylinder. Innovation points are that: a mandrel supporting plate is arranged below the fixing plate; a mandrel connecting rod is arranged on the mandrel supporting plate; central rod floating oil cylinders with double leading-out piston rods are arranged on both sides of the fixing plate; the lower end of the piston rod of each central rod floating oil cylinder is connected with the mandrel supporting plate; a floating pressure oil cylinder is arranged on the female template; and a piston rod of the floating pressure oil cylinder is over against the upper end of the piston rod of each central rod floating oil cylinder. Driving cylinders for driving a mandrel and a female die can run completely independently, so that spray of die releasing oil and die releasing by adding powder are realized successfully, and floating bidirectional pressing can be realized during pressing.
Description
Technical field
The utility model relates to a kind of powder hydraulic press mould bases, particularly a kind of bonded rare earth permanent magnetic thin-walled parts forming die.
Background technology
Along with the development and the maturation of PM technique, increasing material adopts PM technique to make.In the powder hydraulic press mould bases of compacting annular thin wall part, negative template and plug are respectively by taking blame for others and the driving of the central cylinder at built-in ram piston bar center.The shortcoming of this kind mould bases structure is: central cylinder can't independently fully be divided open shop with taking blame for others; Therefore can't spray lubricant smoothly before adding powder; And when adding powder, powder can't be full of former, plug fully and dash down between the annular thin wall cavity that forms, influence compacting quality.In addition, during the demoulding, be prone to cause the damage of annular thin wall part.
Also occurred at present a kind of can the drive negative template and the two-chamber cylinder structure of plug; In same cylinder body upper and lower part plug piston rod and ram piston bar are set respectively; Though the mould bases of this structure has solved the spray lubricant, added powder and release problems, it can't realize the two-way compacting of floating when compacting; Can only unidirectionally suppress, the product density uniformity is relatively poor.
Summary of the invention
The technical problem that the utility model will solve provides a kind of bonded rare earth permanent magnetic thin-walled parts forming die, and the driving cylinder of its driving plug, former is independent operating fully, and when compacting, can realize the two-way compacting of floating.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of bonded rare earth permanent magnetic thin-walled parts forming die; Comprise the cope match-plate pattern, negative template, fixed head and the lower bolster that set gradually from top to bottom, said negative template is connected with lower bolster through pull bar, and lower bolster is by the driving of taking blame for others; Its innovative point is: the below of said fixed head is provided with a plug supporting plate; On the said plug supporting plate plug extension bar is installed, the both sides of said fixed head are equipped with the unsteady oil cylinder of center-pole of the two rod piston rods of band, and the piston-rod lower end of the unsteady cylinder of said center-pole is connected with the plug supporting plate; The compacting oil cylinder that floats also is installed on the said negative template, and the piston rod of said unsteady compacting oil cylinder is over against the piston rod upper end of the unsteady cylinder of center-pole.
Further, be provided with the vibration oil cylinder between said plug supporting plate and the plug extension bar, the cylinder body of said vibration oil cylinder is installed on the plug supporting plate, and vibration oil cylinder piston bar is connected fixing with the plug extension bar.
The advantage of the utility model is: before adding powder, former drives to rise to by taking blame for others and adds the powder position, and plug flushes with following dashing on being installed in fixed head, and makes formation a bigger cavity, lubricating oil spraying smoothly in the former; After having sprayed lubricating oil, being moved forward by the powder box adds this cavity with powder, plug closely knit powder and risen to accomplish and added powder by the center-pole hydraulic oil cylinder driving of floating under the vibration of vibration oil cylinder; When compacting, the unsteady compacting of negative template drive oil cylinder moves down, and the piston rod of the compacting oil cylinder that floats props up the piston rod of the unsteady cylinder of center-pole, and promotion plug supporting plate moves down, and realizes floating synchronously of former and plug, the unsteady two-way compacting of realization; During the demoulding, former drive to descend by taking blame for others, and makes annular element expose former, expansions that do not stress of annular element outer wall, the frictional force of reduction inwall and plug, the plug realization demoulding that can descend smoothly.
Description of drawings
Fig. 1 is the utility model bonded rare earth permanent magnetic thin-walled parts forming die structural representation.
The specific embodiment
As shown in Figure 1, comprise cope match-plate pattern 1, negative template 2, fixed head 3, plug supporting plate 4, lower bolster 5, pull bar 6, take blame for others, plug extension bar 8, vibration oil cylinder 9, center-pole float cylinder 10, compacting oil cylinder 11 floats.
Above-mentioned cope match-plate pattern 1, negative template 2, fixed head 3, plug supporting plate 4, lower bolster 5 set gradually from top to bottom.
Negative template 2 is connected with lower bolster 5 through pull bar 6, and lower bolster 5 is by the driving of taking blame for others.Plug extension bar 8 is installed on the plug supporting plate 4, on the plug extension bar 8 plug is installed, between plug extension bar 8 and plug supporting plate 4, establish vibration oil cylinder 9, the cylinder body of this vibration oil cylinder 9 is installed on the plug supporting plate 4, and vibration oil cylinder piston bar is connected fixing with plug extension bar 8.
The both sides of fixed head 3 are equipped with the unsteady oil cylinder 10 of center-pole of the two rod piston rods of band, and the piston-rod lower end of the unsteady cylinder 10 of center-pole is connected with plug supporting plate 4.The compacting oil cylinder 11 that floats also is installed on the negative template 2, and the piston rod of the compacting oil cylinder 11 that floats is over against the piston rod upper end of the unsteady cylinder 10 of center-pole.
Concrete technological action
Lubricating oil spraying: the formers in the negative template 2 drive to rise to by taking blame for others and add the powder position, and plug flushes with following dashing on being installed in fixed head 3, and make formation a bigger cavity, lubricating oil spraying smoothly in the former;
Add powder: after having sprayed lubricating oil, being moved forward by the powder box adds the cavity that forms in the above-mentioned former with powder, and plug is closely knit powder under the vibration of vibration oil cylinder 9, and is risen to accomplish and added powder by the center-pole oil cylinder 10 that floats;
Compacting: the unsteady compacting of negative template 2 drives oil cylinder 11 moves down, and the piston rod of the compacting oil cylinder 11 that floats props up the piston rod of the unsteady cylinder 10 of center-pole, and promotion plug supporting plate 4 moves down, and realizes floating synchronously of former and plug, the unsteady two-way compacting of realization;
The demoulding: former drive to descend by taking blame for others, and makes annular element expose former, and expansions that do not stress of annular element outer wall reduces the frictional force of inwall and plug, and the realization demoulding smoothly can descend during the unsteady cylinder 10 driving plugs of center-pole.
