Abstract

The utility model provides an adjustable punching machine, which relates to equipment of press working. In fact, on the basis of the multibar linkage, the utility model realizes regulation by increasing the movable slide blocks and the controlling pieces which can adjust the initial position of the movable slide blocks, so that the working mechanism of the punching machine has adjustable ability which can adjust operating pressure and working travel. The utility model which expands the usage range of the punching machine is suitable for various conditions of processing sheets, blanking, punching, shaping, stretching, bending, etc. and is especially for small-and-medium-size punching machine and manual punching machine.

Description

Adjustable punching machine

The utility model relates to a kind of punch process equipment, and it belongs to forcing press.

Punch press is generally by power source, transmission mechanism, and flywheel, operating mechanism, clutch and workbench are formed.Close with this punching machine structure is the punch press with many bars operating mechanism.Multi-bar linkage comprises: crank (3), side link (4), rocking bar (5), work connecting rod (8) and work slide block (9).It is fast that the multi-bar linkage punch press has opening speed, and speed of working stroke is slow and steady, the advantage that stressing conditions is good.But, multi-bar linkage connects because being all hinge, in other condition one regularly, the impulse stroke of punch press and operating pressure also are certain, also are, multi-bar linkage itself does not possess regulating power---and unadjustable operating pressure and impulse stroke are very limited its range of work.

Therefore, designing a kind of new-type structure punch press, both kept the advantage of multi-bar linkage punch press, have regulatory function again, is the purpose of this utility model and task.

Essence of the present utility model is on the basis of multi-bar linkage, realizes regulating by the control piece (7) that increases motion slide block (6) and adjustable movement slide block (6) initial position.Control piece (7) is articulated on the motion slide block (6) with work connecting rod (8), motion slide block (6) and rocking bar (5) at bar to being slidingly connected.The regulative mode of control piece (7) can have multiple changing, those of ordinary skill is easily realized, this case exemplifies a kind of adjustment structure: the regulatory function of control piece (7) can be by rod member (74) regulating rod (75), screw thread compact heap (71), and slide block (72) and axle (73) are realized.Regulating rod is a Cylinder, has two plane of orientations that do not wait apart from garden axis of a cylinder heart distance on it at least; Regulating rod (75) and screw thread compressing member (71) be by rack support, and rotatable; Axle (73) is supported by slide block (72), its upper connecting rod spare (74), and rod member (74) is hinged with motion slide block (6).By selecting different locating surfaces, compress by screw thread compact heap (71) again, slide block (72) can obtain different fixed positions.The position adjustments of slide block (72) reaches motion slide block (6) through axle (73), rod member (74), has realized adjustment movement slide block (6).Go up the purpose of initial position (relative position of the static luck movable slider of operating mechanism (6) on rocking bar (5) also promptly) at rocking bar (5).Because the initial position difference of motion slide block (6) on rocking bar (5) changed the force rate relation of operating mechanism, thereby reached the purpose of regulating operating pressure and impulse stroke.Transfer big operating pressure, impulse stroke reduces thereupon; Turn operating pressure down, impulse stroke increases.According to the adjustable range that requires of operating pressure and impulse stroke, can determine the concrete structure size.This kind adjustment structure is discontinuous formula regulative mode, in addition, also can adopt the continous way adjustment structure.

Because the utility model has adopted the multi-bar linkage that has control piece (7), has changed traditional fixed work structuring, makes punch press operating mechanism itself have regulating power, compare with identical tonnage punch press, enlarged the scope of application of punch press, adapted to different processing situations, thin plate, blanking, punching stretches shaping, impression, processing such as bending is particularly outstanding.Simultaneously, because of the adjustability of operating mechanism, also can simplify the transmission mechanism of punch press, motor (1) can directly reach flywheel (2) by belt with power, thereby noiselessness, vibrates little.In addition, it is fast that this punch press also has opening speed, and speed of working stroke is slow and steady, the characteristics that stressing conditions is good.

If adopt the utility model that existing punch press is undergone technological transformation, then can expand original operating pressure more than one times, make the bigger function of existing punch press performance.The utility model is particularly useful for middle-size and small-size or hand punch.

Description of drawings.Fig. 1 is the front view of punch press; Fig. 2 cuts open figure for the office of overlooking of punch press; Fig. 3 is a schematic diagram; (1) be motor, (2) are flywheel, and (3) are crank, and (4) are side link, and (5) are rocking bar, and (6) are the motion slide block, and (7) are control piece, and (8) are the work connecting rod, and (9) are the work slide block; (71) be the screw thread compact heap, (72) are slide block, and (73) are axle, and (74) are rod member, and (75) are regulating rod.
