Description

Burr removing machine for metal powder injection molding work pieces process
Technical field
The utility model relates to field of powder metallurgy, specially a kind of to go for metal powder injection molding work pieces process Burr machine.
Background technique
Metal injection moulding is a kind of forming that the plasticising mixture by metal powder and its binder is injected in model Method.It is first to mix selected powder with binder, and then mixture is pelletized required for injection moulding again Shape.Polymer assigns the feature of its VISCOUS FLOW to mixture, and facilitates the uniform of forming, mould filling and powder packing Property.Binder is excluded after forming, then degreased blank is sintered.Some sintered products are also possible to further to be densified Processing, heat treatment or machining.Sintered products not only have complicated shape as injection molding of plastics method resulting product and In high precision, and there is the physics close with forging, chemistry and mechanical performance.The technology be suitble to produce in enormous quantities it is small-sized, The manufacture of accurate, 3D shape complexity and the metal parts required with property.
It will form flash by its surface of the workpiece of metal powder injection molding and be also referred to as burr, and since workpiece passes through Metal powder integral injection molding, therefore its flash is distributed in the edge of workpiece, traditional removing method mostly uses polishing, this kind of side Formula working efficiency is lower, it is difficult to while to the processing of multiple workpiece.
Utility model content
The technical issues of solution
In view of the deficiencies of the prior art, the utility model provides a kind of for metal powder injection molding work pieces process Burr removing machine solves the problems, such as low to the flash removal efficiency of metal powder injection molding part.
Technical solution
In order to achieve the above object, the utility model is achieved by the following technical programs: one kind is infused for metal powder The burr removing machine of shaping workpiece processing is penetrated, including pedestal, the upper surface of the pedestal are equipped with no less than one lower punch, often Engaging is placed with workpiece on a lower punch, and the two sides of the base upper surface are welded with vertical plate, the tops of two vertical plates it Between be provided with top plate, the both ends of top board undersurface are mounted on lifting device, are equipped with crossbeam between the bottom of two lifting devices, The upper and compatible upper cavity die of size corresponding with lower punch position is provided on the crossbeam.
It further limits, the lifting device is the one of which of oil cylinder or electric pushrod.
It further limits, the inside of the vertical plate vertically offers sliding slot, and the both ends of crossbeam, which are provided with to slide with sliding slot, to be connected The sliding block connect.
It further limits, the lifting device is located at the inside of sliding slot, and the bottom end of lifting device is fixedly connected with a slide block.
It further limits, integrally formed with side plate, the side plate of upper cavity die passes through in the outside of the upper cavity die and lower punch The side plate of the connection of the bottom surface of bolt and crossbeam, lower punch is connected by the upper surface of bolt and pedestal, this kind is to upper cavity die under The fixed form of punch-pin can facilitate to upper cavity die and lower punch replacement, be handled with being suitable for the workpiece of different sizes and shapes.
This is used for the burr removing machine of metal powder injection molding work pieces process, using the pressing between upper cavity die and lower punch Excision is pressed to the flash of the edge of work, this kind of flash removing method is easy to operate, while being arranged on pedestal and crossbeam multiple Lower punch and upper cavity die can carry out flash to multiple workpiece and squeeze excision, and burr removing efficiency is higher, by lifting device to cross Beam carries out descending operation, reduces human input, improves work efficiency, and sliding slot plays the role of guide and limit to sliding block, Keep the pressing between upper cavity die and lower punch more accurate.
Detailed description of the invention
Fig. 1 is the utility model section view;
Fig. 2 is the utility model structure diagram.
In figure: 1 pedestal, 2 vertical plates, 3 upper cavity dies, 4 sliding blocks, 5 lifting devices, 6 top plates, 7 crossbeams, 8 sliding slots, 9 lower punches, 10 Workpiece, 11 side plates.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: one kind adds for metal powder injection molding workpiece The burr removing machine of work, including pedestal 1, the upper surface of pedestal 1 are equipped with no less than one lower punch 9, on each lower punch 9 Engaging is placed with workpiece 10, and the two sides of 1 upper surface of pedestal are welded with vertical plate 2, are provided with top plate between the top of two vertical plates 2 6, the both ends of 6 bottom surface of top plate are mounted on lifting device 5, are equipped with crossbeam 7 between the bottom of two lifting devices 5, on crossbeam 7 It is provided with the upper and compatible upper cavity die 3 of size corresponding with 9 position of lower punch.
Lifting device 5 is the one of which of oil cylinder or electric pushrod, and lifting device 5 passes through conducting wire and workshop at work Control panel electrical connection by the on-off of electric current in control panel lifting controllable device 5, and then is played control crossbeam 7 and is risen With the purpose of decline.
