A kind of pneumatic punching machine
The present invention relates to the punch press field of mechanical technique, specifically, it is a kind of pneumatic punching machine.
Punch press is a kind of important lathe of machining, is used for punching out sheet material.A lot of punch presses are only used for processing less workpiece, sheet material continuous feeding normally, punching press continuously.Traditional pneumatic punching machine, the pressure of generation is less, produces bigger stamping press if desired, then must select the cylinder of big cylinder diameter, makes that the volume of punch press is excessive, and having relatively high expectations of place can not be satisfied the modern production requirement more and more higher to the punch press performance.
Summary of the invention
The objective of the invention is by a kind of cylinder and connecting rod reinforcement structure Design, the pneumatic punching machine of making not only volume is less, and impulse force can be carried out the amplification of several times, satisfies the requirement of modern production to punch press and production efficiency.
For achieving the above object, the present invention realizes by following technological means: a kind of pneumatic punching machine, comprise base, support, cylinder, cam, fixed head and drift, vertically be provided with support on the described base, the right side, upper end of support is provided with fixed head, and the upper end of described fixed head is equipped with cylinder, and this cylinder moves up and down by the cam that piston rod can drive the fixed head below, this cam lower left quarter is the arcwall face structure, and can pass support can be that cambered surface contacts with pulley; Left side, described support upper end is provided with gripper shoe, and gripper shoe is provided with can control the adjustment stroke apparatus that the connecting plate that is positioned at the gripper shoe below moves up and down; Described connecting plate is connected with connecting rod on, should go up connecting rod and flexibly connect a lower link by a pulley, this lower link lower end connects a slide block, and this slide block can slide up and down in the limited block that is fixed on the support left side, and the end of described slide block is fixed with a drift.
Compared with prior art, the invention has the beneficial effects as follows: owing to adopt said structure, adopt cylinder as power resources, cylinder drive cam acts on and connects on the pulley of going up connecting rod and lower link, makes pulley do curvilinear motion, not only give the downward power of pulley level, also give the power of pulley one horizontal direction, pulley passes to upper and lower strut with the power of this horizontal direction and then becomes the power of vertical direction, makes the corresponding active force of twice amplification of connecting rod, improve impulse force, realize that the twice of impulse force is amplified.Novel structure of the present invention is skillfully constructed, and has market value widely.
Description of drawings

Accompanying drawing 2 is the end-state structural representation of a kind of pneumatic punching machine of the present invention.
Each label is respectively among the figure: (1) base, (2) support, (3) fixed head, (4) gripper shoe, (5) cylinder, (6) cam, (7) adjust stroke apparatus, (8) connecting plate, (9) go up connecting rod, (10) lower link, (11) pulley, (12) slide block, (13) limited block, (14) drift.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1, the present invention: a kind of pneumatic punching machine, comprise base 1, support 2, cylinder 5, cam 6, fixed head 3 and drift 14, vertically be provided with support 2 on the described base 1, the right side, upper end of support 2 is provided with fixed head 3, and the upper end of described fixed head 3 is equipped with cylinder 5, and this cylinder 5 moves up and down by the cam 6 that piston rod can drive the fixed head below, these cam 6 lower left quarters are the arcwall face structure, and can pass support 2 can contact for cambered surface with pulley 11; Described support 2 upper ends left sides is provided with gripper shoe 4, and gripper shoe 4 is provided with can control the adjustment stroke apparatus 7 that the connecting plate 8 that is positioned at gripper shoe 4 belows moves up and down; Described connecting plate 8 is connected with connecting rod 9 on, should go up connecting rod 9 and flexibly connect a lower link 10 by a pulley 11, these lower link 10 lower ends connect a slide block 12, this slide block 12 can slide up and down in the limited block 13 that is fixed on support 1 left side, and the end of described slide block 12 is fixed with a drift 14.
In conjunction with Fig. 1 and Fig. 2, when the present invention works, start cylinder 5, cylinder 5 drives cam 6 by piston rod and acts on the pulley 11, not only gives pulley 11 1 power vertically downward, also gives level power left; Because the upper end of the last connecting rod 9 that pulley 11 connects is fixed, so connecting rod 9 is gone up in the power drive left of this level and lower link 10 moves downward, make it become motion vertically downward, thereby realize the amplification of impulse force impulse force in this way, finally process by 14 pairs of workpiece of drift of slide block 12 lower ends.
The embodiment that the present invention exemplified not is the qualification to oneself, every content that does not break away from technical solution of the present invention,, all still belong in the technical scheme scope of the present invention any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present invention.
