Abstract
The invention discloses a double-toggle-rod punch guiding device which comprises a movable table top, a guiding block for guiding, a fixing shaft and a pair of driving mechanisms. A guiding groove is formed in the center of the movable table top. The guiding block is arranged in the guiding groove in a sleeved mode. A circular hole is formed in the center of the guiding block. The fixing shaft penetrates through the circular hole of the guiding block. The two ends of the fixing shaft are fixed on a punch support. The pair of driving mechanism is hinged to the upper end of the movable table top and is arranged symmetrically relative to the guiding groove. The driving mechanisms are connected to the upper end of the movable table top, when the driving mechanisms drive the movable table top to move up and down, the movable table top moves up and down along the guiding block under the effect of the guiding groove and can swing around the fixing shaft, the center of the movable table top is corrected automatically, and under the common effect of a fixed table top and the movable table top, the purpose of workpiece stamping is achieved.
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 is that sheet metal is carried out to punching press.The punch press of most adopts the combination of dual-elbow-bar mechanism and toggle to drive on moveable top, lower reciprocating motion is carried 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 lateral surface using moveable top is as spigot surface, and the shortcoming that fixed guide face is positioned at the guider in activity-oriented face outside is: the size of moveable top is subject to the restriction of fixed guide face, if need to increase the area of moveable top, just must first to increase the area of fixed guide face, can make like this manufacturing process complexity of machine, manufacturing cost strengthens, the reliability variation of machine.Therefore,, in order to make the size of moveable top not be subject to the restriction of fixed guide face, must change the current this lateral surface using moveable top and be positioned at as spigot surface and fixed guide face the guidance mode in activity-oriented face outside.
[summary of the invention]
The object of the invention is to overcome the defect of above-mentioned prior art, a kind of toggle link punch press guider is provided, 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 of driving mechanism for leading; Wherein, on the center of moveable top, be 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 of driving mechanism and moveable top, and be symmetrical arranged with respect to gathering sill.
The present invention further improves and is, guide pad and gathering sill matched in clearance.
The present invention further improves and is, gathering sill is cross gathering sill.
With respect to prior art, the invention has the beneficial effects as follows:
The present invention arranges guide pad by the center at moveable top, in the time that toggle link driving mechanism drives the upper and lower motion of moveable top, moveable top can be along the upper and lower slip of guide pad, and can swing around fixed axis, this structure is not subject to the restriction of fixed guide face, and can make moveable top area increase, and improve the performance of machine, improve the condition of work of machine; And can reach make machine parts simplify, manufacturing cost reduce, machine reliability increase object.
[brief description of the drawings]
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 of 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.
Referring to 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 of driving mechanism 7 for leading; Wherein, on the center of moveable top 3, be 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, guide pad 5 just can swing around fixed axis 4 like this, and gathering sill 6 can be along the upper and lower slip of guide pad 5, 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 of driving mechanism 7 and moveable top 3, and be symmetrical arranged with respect 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, in the time that 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 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 presses.This structure is not subject to the restriction of fixed guide face, and can make the area of moveable top 3 increase.Improve the serviceability of machine, improved the condition of work of machine; And can reach make machine parts simplify, manufacturing cost reduce, machine reliability increase object.
