Abstract
The invention discloses a kind of toggle link punch press guider, comprising moveable top, guide pad, fixed axis and a pair driving mechanism for leading; Wherein, the center of moveable top is provided with gathering sill, guide pad is set in gathering sill, the center of guide pad offers circular hole, fixed axis is through the circular hole of guide pad, its two ends are fixed on frame of punch, the upper end chain connection of a pair driving mechanism and moveable top, and are symmetrical arranged relative to gathering sill.The present invention is connected with driving mechanism due to the upper end at moveable top, when the upper and lower motion of driving mechanism driving moveable top, moveable top moves along guide pad is upper and lower under the effect of gathering sill, and can swing around fixed axis, the center of automatic calibration moveable top, under the acting in conjunction of fixed mesa and moveable top, reach the object to workpiece punching press.
Description
[technical field]
The present invention relates to a kind of guider, particularly a kind of toggle link punch press guider.
[background technology]
The effect of punch press carries out punching press to sheet metal.Current most punch press adopts the combination of dual-elbow-bar mechanism and toggle to drive on moveable top, lower reciprocating motion carries out punching press to sheet metal, on, lower reciprocating spigot surface is positioned at the lateral surface of moveable top, as Chinese invention patent CN201210044752.9, this using the lateral surface of moveable top as spigot surface, and the shortcoming of guider that fixed guide face is positioned at outside activity-oriented face is: the size of moveable top is subject to the restriction in fixed guide face, if need the area increasing moveable top, just first must to increase the area in fixed guide face, the manufacturing process of machine can be made so complicated, manufacturing cost strengthens, the less reliable of machine.Therefore, in order to the size making moveable top is by the restriction in fixed guide face, must change current this using the lateral surface of moveable top as spigot surface and fixed guide face is positioned at guidance mode outside activity-oriented face.
[summary of the invention]
The object of the invention is to the defect overcoming above-mentioned prior art, provide a kind of toggle link punch press guider, it can make the manufacturing cost of toggle link punch press guider reduce, and moveable top area is increased.
For achieving the above object, the technical solution used in the present invention is:
A kind of toggle link punch press guider, comprises moveable top, guide pad, fixed axis and a pair driving mechanism for leading; Wherein, the center of moveable top is provided with gathering sill, guide pad is set in gathering sill, the center of guide pad offers circular hole, fixed axis is through the circular hole of guide pad, its two ends are fixed on frame of punch, the upper end chain connection of a pair driving mechanism and moveable top, and are symmetrical arranged relative to gathering sill.
The present invention improves further and is, guide pad and gathering sill matched in clearance.
The present invention improves further and is, gathering sill is cross gathering sill.
Relative to prior art, the invention has the beneficial effects as follows:
The present invention arranges guide pad by the center at moveable top, when the upper and lower motion of toggle link driving mechanism driving moveable top, moveable top can along the upper and lower slip of guide pad, and can swing around fixed axis, this structure is not by the restriction in fixed guide face, and moveable top area can be made to increase, improve the performance of machine, improve the condition of work of machine; And can reach machine parts is simplified, manufacturing cost reduces, the object that machine reliability increases.
[accompanying drawing explanation]
Fig. 1 is the overall structure schematic diagram of a kind of toggle link punch press of the present invention guider.
Fig. 2 be Fig. 1 A-A to partial sectional view.
In figure: 1, fixed mesa; 2, sheet metal; 3, moveable top; 4, fixed axis; 5, guide pad; 6, gathering sill; 7, a pair driving mechanism; 8, frame of punch.
[detailed description of the invention]
Below in conjunction with accompanying drawing, structural principle of the present invention and operation principle are described in further detail.
See Fig. 1, a kind of toggle link punch press of the present invention guider, comprises moveable top 3, guide pad 5, fixed axis 4 and a pair driving mechanism 7 for leading; Wherein, the center of moveable top 3 is provided with gathering sill 6, guide pad 5 is set in gathering sill 6, the center of guide pad 5 offers circular hole, and fixed axis 4 is through the circular hole of guide pad 5, and its two ends are fixed on frame of punch 8, such guide pad 5 just can swing around fixed axis 4, and gathering sill 6 along the upper and lower slip of guide pad 5, can it is emphasized that the symmetrical center line of gathering sill 6 overlaps with the symmetrical center line of moveable top 3, the width of gathering sill 6 is symmetrical with the center line of moveable top 3; The upper end chain connection of a pair driving mechanism 7 and moveable top 3, and be symmetrical arranged relative to gathering sill 6.
Wherein, guide pad 5 and gathering sill 6 matched in clearance; Gathering sill 6 is cross gathering sill.
The course of work of the present invention is as follows: owing to being connected with driving mechanism 7 in the lower end of moveable top 3, when driving mechanism 7 drives the upper and lower motion of moveable top 3, moveable top 3 moves along guide pad 5 is upper and lower under the effect of gathering sill 6, and can swing around fixed axis 4, the center of automatic calibration moveable top.Under the acting in conjunction of fixed mesa 1 and moveable top 3, reach the object to sheet metal 2 punching press.This structure not by the restriction in fixed guide face, and can make the area of moveable top 3 increase.Improve the serviceability of machine, improve the condition of work of machine; And can reach machine parts is simplified, manufacturing cost reduces, the object that machine reliability increases.
