Description
Technical field
The present invention relates to a kind of magnetic material forming hydraulic press, particularly a kind of full-automatic wet type magnetic material forming hydraulic press of can the auto-compensation feed time guaranteeing to suppress consistency of thickness.
Background technology
Along with development and the maturation of PM technique, increasing material adopts PM technique to be made.It first becomes pie by powder shaping press by powder compaction, then makes final products by sintering.Rare earth permanent-magnetic material is a kind of comparatively special material, and the alloy that it forms samarium, neodymium mixed rare-earth metal and transition metal, with powder metallurgy process compacting die mould sintering, a kind of magnetic material made after magnetizing in magnetic field.
When carrying out magnetic material compressing, due to reasons such as different batches, cause the product thickness of compacting to have certain otherness, affect product quality.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of full-automatic wet type magnetic material forming hydraulic press of can the auto-compensation feed time guaranteeing to suppress consistency of thickness.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of full-automatic wet type magnetic material forming hydraulic press, mainly comprise entablature, workbench, described workbench and entablature are connected and fixed by the guide pillar of four jiaos, the slide block be slidably matched with guide pillar is set between described entablature and workbench, slide block is driven by the master cylinder be arranged on entablature, arrange and take blame for others in workbench, workbench one side arranges automatic feeding mechanism, its innovative point is: also comprise a product thickness checkout gear, this product thickness checkout gear can detect the position of seaming chuck and push-down head when compressing automatically, and this position signalling is transferred to Programmable Logic Controller, one Programmable Logic Controller, be converted into the product actual (real) thickness and, by the contrast of the product standard thickness of this product actual (real) thickness and setting, automatically calculate the reinforced make-up time of automatic feeding mechanism for the position signalling by the product thickness checkout gear.
Further, described product thickness checkout gear comprises top offset sensor and bottom offset sensor, and described entablature lower end is fixed with a upper guide post stretched in slide block, and the top offset sensor that is positioned at guide post one side is installed in slide block; Take blame for others on the connecting plate of taking blame for others of upper end the lower guide post stretched into downwards in workbench is installed, the bottom offset sensor that is positioned at lower guide post one side is installed in workbench.
Further, the guide post guide pin bushing be slidably matched with lower guide post is installed on described workbench.
The invention has the advantages that: during work, the product thickness checkout gear detects the position of upper and lower pressure head when compressing, after this signal is transferred to Programmable Logic Controller, calculated the thickness of product by Programmable Logic Controller, and itself and standard thickness comparing calculation are gone out to feed in raw material the make-up time, readjust feed time, make the thickness of product reach unanimity, improve the quality of products, the rate of reducing the number of rejects and seconds.
The accompanying drawing explanation
Fig. 1 is the full-automatic wet type magnetic material of the present invention forming hydraulic press front view.
Fig. 2 is the full-automatic wet type magnetic material of the present invention forming hydraulic press side view.
The specific embodiment
As shown in Figure 1, 2, comprise entablature 1, workbench 2, guide pillar 3, slide block 4, master cylinder 5, take blame for others 6, top offset sensor 7, bottom offset sensor 8, upper guide post 9, lower guide post 10.
Above-mentioned workbench 2 is connected and fixed with the guide pillar 3 of entablature 1 by four jiaos, the slide block 4 be slidably matched with guide pillar 3 is set between entablature 1 and workbench 2, slide block 4 is driven by the master cylinder 5 be arranged on entablature 1, and the interior setting of workbench 2 takes blame for others 6, and workbench 2 one sides arrange automatic feeding mechanism.
Also be provided with a product thickness checkout gear on hydraulic press, this product thickness checkout gear can detect the position of seaming chuck and push-down head when compressing automatically, and this position signalling is transferred to Programmable Logic Controller.Its structure is: the product thickness checkout gear comprises top offset sensor 7 and bottom offset sensor 8, and entablature 1 lower end is fixed with a upper guide post 9 stretched in slide block 4, and the top offset sensor 7 that is positioned at guide post 9 one sides is installed in slide block 4; Take blame for others on the connecting plate of taking blame for others of 6 upper ends the lower guide post 10 stretched into downwards in workbench 2 is installed, the bottom offset sensor 8 that is positioned at lower guide post 10 1 sides is installed in workbench 2.The guide post guide pin bushing 11 be slidably matched with lower guide post 10 also is installed on workbench 2.
Programmable Logic Controller is for being converted into the position signalling of the said goods thickness detection apparatus the product actual (real) thickness and, by the contrast of the product standard thickness of this product actual (real) thickness and setting, automatically calculating the reinforced make-up time of automatic feeding mechanism according to thickness difference.
Operation principle: during compacting, utilize the product thickness checkout gear can automatically detect the position of seaming chuck and push-down head when compressing, and this position signalling is transferred to Programmable Logic Controller; The actual (real) thickness of product when Programmable Logic Controller calculates this time compacting action according to this position signalling, and the standard thickness of this actual (real) thickness and setting is contrasted, if actual (real) thickness is less than standard thickness, control automatic feeding mechanism and reduce certain feed time, if actual (real) thickness is greater than standard thickness, controlling automatic feeding mechanism increases certain feed time, thereby makes the product thickness next time the suppressed thickness that constantly is near the mark.
