A kind of pneumatic press
The utility model relates to a kind of pneumatic press.
Punch press is a kind of simple and practical pressworking equipment, and because it is made simply, low price, have purposes widely, as press for powder metallurgical forming, and stamping machine, forging machine etc.Some need the powdered metal parts of pressure bar part, also often use punch press processing.Punch press utilizes cam to rotatablely move to be converted into straight line and pumps, and therefore the motion of this conversion is a kind of rigidity.Yet, have and longly have shortly at the workpiece of actual production, in punch press pressure bar part process, produce unavoidably workpiece and stand rigid shock so, seriously occur that workpiece is bad, or the tool breakage of pressure bar part.Therefore, the applicant researches and develops and a kind ofly excellent part can be pressed onto to position, is unlikely to again the equipment that workpiece or tool are damaged by pressure, thereby solves the deficiency of punch press.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and excellent part can be pressed onto to position, is unlikely to again the pneumatic press that workpiece or tool are damaged by pressure.
Utility model purpose of the present utility model is achieved in that a kind of pneumatic press, comprise that base reaches the tool for pressure bar part workpiece, tool is installed on base, wherein, described base is provided with bracing frame, bracing frame is provided with excellent part is pressed into to the Pneumatic assembly on the position, hole of workpiece, and the corresponding tool of Pneumatic assembly is installed on bracing frame.
According to above-mentioned, be optimized, described Pneumatic assembly comprises cylinder, air-operated solenoid valve, gauge tap, and gauge tap is connected with air-operated solenoid valve, and air-operated solenoid valve is connected with cylinder, and the corresponding tool of cylinder is installed on bracing frame.
According to above-mentioned, be optimized, described gauge tap is connected with air-operated solenoid valve by wire.
According to above-mentioned, be optimized, described gauge tap is in base the place ahead.
According to above-mentioned, be optimized, described cylinder is connected with air-operated solenoid valve by tracheae.
Be optimized according to above-mentioned, on described cylinder, pressure head arranged, pressure head is connected with the piston of cylinder, and the pressure head of air-operated solenoid valve control cylinder moves up, and can move down and excellent part is suppressed on workpiece by the control cylinder pressure head.
According to above-mentioned, be optimized, the pressure head of described cylinder is through bracing frame the top in tool.
The utility model is researched and developed for the weak point of existing punch press, and its advantage is as follows:
This product is mainly controlled by cylinder, simple structure, make be more prone to and cost low; And, control ram travel by the piston rod stroke of air pressure control cylinder, like this, only need be according to practical adjustments air pressure.Pressure head is in the process pressed down, as long as the anti-support force be subject to reaches the level of suffered air pressure, pressure head stops pressing down.Therefore, after this equipment realizes that the pressure bar part puts in place, can avoid again the unnecessary breakage of workpiece and tool, overcome the deficiency of punch press rigidity stroke.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Shown in Fig. 1, pneumatic press described in the utility model, it comprises that base 1 reaches for pressure bar part 21 tool 3 in workpiece 2, tool 3 is installed on base 1.Wherein, described base 1 is provided with bracing frame 4, for pressure bar part 21 in the tool 3 of workpiece 2 specifically in bracing frame 4, bracing frame 4 is provided with excellent part 21 is pressed into to the Pneumatic assembly on the position, hole of workpiece 2, the corresponding tool 3 of Pneumatic assembly is installed on bracing frame 4.This Pneumatic assembly comprises cylinder 5, air-operated solenoid valve 6, gauge tap 7, and gauge tap 7 is in base 1 the place ahead, and gauge tap 7 is connected with air-operated solenoid valve 6 by wire 8, and air-operated solenoid valve 6 passes through tracheae 9 and is connected with cylinder 5.That is, cylinder 5, under air-operated solenoid valve 6 is controlled, pumps.And on this cylinder 5, having pressure head 10, pressure head 10 1 ends to be connected with the piston of cylinder 5, pressure head 10 other ends are through the top of bracing frame 4 in tool 3.When work, the air pressure at air-operated solenoid valve 6 control cylinder 5 two ends, drive the piston driving pressure head 10 of cylinder 5 to pressing down, and realizes excellent part 21 is pressed on the position, hole of workpiece 2.After pressure head 10 is pressed on workpiece 2 by excellent part 21, the anti-support force that pressure head 10 is subject to reaches the air pressure level that gauge tap 7 sets, and makes pressure head 10 stop pressing action.
Like this, this product is mainly controlled its stroke by air pressure, according to workpiece, suffered pressure arranges the stress level of air pressure, effectively overcome punch press rigidity stroke deficiency, simple structure, make easily, cost is low, and it is slow than speed under punch press, can effectively prevent that workpiece 2 and tool 3 from damaging the phenomenon of splashing, safer for manually-operated.
Above-mentioned specific embodiment is only the utility model effect specific embodiment preferably, and all or pneumatic press of being equal to identical with this structure, all in the application's protection domain.
