Detailed description of the invention
Shown in Fig. 2, the small-sized hand-operated punch press of one of the present embodiment, comprise handle 1, punching press frame 2, base plate, all be arranged on the slide block 3 in punching press frame 2 and the slide-driving device 4 for driving slide block 3 to move, it is characterized in that: described slide-driving device 4 comprises rotating shaft 41, for being fixed on two rigid bearings 42 on punching press frame 2 and being arranged on two cams 43 between rigid bearing 42, described two rigid bearings 42 and the equal coaxial sleeve of cam 43 are located in rotating shaft 41, one end of described rotating shaft 41 is fixedly connected with handle 1 one end, described slide block 3 is conflicted and is connected with cam 43, described slide block 3 is provided with deep-slotted chip breaker 31 with cam 43 conflict one end, described deep-slotted chip breaker 31 bottom lands and cam 43 are inconsistent, described slide block 3 is provided with resetting means 5.
By adopting technique scheme, when in the time using small-sized hand-operated punch press, handle 1 will drive rotating shaft 41 to rotate, due to the setting of rigid bearing 42, punching press frame 2 can not be affected, rotating shaft 41 will be with moving cam 43 to rotate, cam 43 will carry out relative sliding on slide block 3, due to the reason of cam 43 structures, distance between slide block 3 and rotating shaft 41 will change, so just can reach a rotation by handle 1 and transmit the effect for the vertical motion of slide block 3, and due to the setting of deep-slotted chip breaker 31, just can make cam 43 motion that can better match with it, cam 43 is just not easy slippage from slide block 3, punch press is just not easy to break down, wherein deep-slotted chip breaker 31 is the enclosed deep-slotted chip breaker 31 of surrounding, notch arranges towards cam 43, owing to can better driving slide block 3 for cam 43, so in the process of producing, need between deep-slotted chip breaker 31 and cam 43, add lubricating oil to the finished product stage, and enclosed setting, can effectively avoid lubricating oil to spill in deep-slotted chip breaker 31, reduce the use of lubricating oil, and deep-slotted chip breaker 31 does not wrap cam 43 completely, cam 43 is in the process of rotating, point on cam 43 presents elliptic motion, because do not wrap cam 43 completely, so the motion in the some horizontal direction on cam 43 is not delivered on slide block 3, slide block 3 just can not produce left and right and be offset.
Described resetting means 5 comprises spring 52 and is set in the conflict piece 51 on slide block 3, and described spring 52 one end and conflict piece 51 dorsad deep-slotted chip breaker 31 1 sides are conflicted and be connected, and the other end is connected with 2 conflicts of punching press frame.
By adopting technique scheme, when slide block 3 is depressed, conflict piece 51 also can dead spring 52, owing to thering is conflict relation between spring 52 and punching press frame 2, so spring 52 will be compressed, when slide block 3 is not toward pressing down when, spring 52 will carry out the process of a recovery, slide block 3 is pushed up again, and this process is owing to being the process that spring 52 is carried out to a compression, so spring 52 can bear larger power, spring 52 can use common on the market cylindrical stage clip herein, this spring 52 can well reach an effect that slide block 3 is resetted, make also convenience very, can also be according to the shape of slide block 3, special go out with the suitable spring 52 of slide block 3 shape sizes, compare like this with helical spring 52 and can effectively save the space in punching press frame 2.
Described rotating shaft 41 with respect to the other end of handle 1 also coaxial sleeve be provided with belt pulley 6.
By adopting technique scheme, by the setting of belt pulley 6, if when not thinking manually to use punch press, only need to add outside a motor and belt, by belt, belt pulley 6 and machine shaft 41 are coupled together, motor just can drive belt pulley 6 to rotate like this, and in the process manually using before, it is the vertical displacement of realizing slide block 3 by the rotation of cam 43, so equally also can be with moving cam 43 by motor, and little many in the space more shared than bent axle, the shared space of cam 43, and the process cam 43 using be directly and slide block 3 inconsistent in, connecting rod is not set, so can further dwindle the required space taking of whole slide-driving device 4.
Described slide block 3 is also fixedly connected with the rubber buffer 7 being arranged between slide block 3 and mould away from one end of cam 43.
By adopting technique scheme, cushion pad can effectively carry out the process of whole punching press the effect of a buffering, people is used more comfortable, can also reduce the suffered impact of slide block 3, increases the service life of slide block 3.
Described handle 1 is connected by screw with rotating shaft 41.
By adopting technique scheme, if drive rotating shaft 41 with motor, handle 1 can be disassembled from rotating shaft 41, prevent in the process of operation handle 1 people that injures.
The utlity model has following advantage: in work, cam 43 will rotate, due to the reason of cam 43 structures, cam 43 will prop up slide block 3 and it is moved downward, and the setting of deep-slotted chip breaker 31, can effectively anti-limited slip block 3 and cam 43 between the phenomenon of slippage occur, punch press is also just not easy to break down like this, when in the time using small-sized hand-operated punch press, handle 1 will drive rotating shaft 41 to rotate, due to the setting of rigid bearing 42, punching press frame 2 can not be affected, rotating shaft 41 will be with moving cam 43 to rotate, cam 43 will carry out relative sliding on slide block 3, due to the reason of cam 43 structures, distance between slide block 3 and rotating shaft 41 will change, so just can reach a rotation by handle 1 and transmit the effect for the vertical motion of slide block 3, and due to the setting of deep-slotted chip breaker 31, just can make cam 43 motion that can better match with it, cam 43 is just not easy slippage from slide block 3, punch press is just not easy to break down, wherein deep-slotted chip breaker 31 is the enclosed deep-slotted chip breaker 31 of surrounding, notch arranges towards cam 43, owing to can better driving slide block 3 for cam 43, so in the process of producing, need between deep-slotted chip breaker 31 and cam 43, add lubricating oil to the finished product stage, and enclosed setting, can effectively avoid lubricating oil to spill in deep-slotted chip breaker 31, reduce the use of lubricating oil, and deep-slotted chip breaker 31 does not wrap cam 43 completely, cam 43 is in the process of rotating, point on cam 43 presents elliptic motion, because do not wrap cam 43 completely, so the motion in the some horizontal direction on cam 43 is not delivered on slide block 3, slide block 3 just can not produce left and right and be offset.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
