Abstract
A connecting device for connecting a connecting bar and a top knife rest in a hydraulic roll-turning metal plate shearer belongs to the technical field of metal plate shearer machine and is characterized in that the connecting bar inside a shearer transmission mechanism is of a Y structure, the Y type at the upper end is hinged with a hydraulic cylinder rod and a push rod, the lower end is hinged with the top knife rest by a pin roll. A pin roll hole at the lower end of the connecting bar is provided with left and right eccentric sleeves, excircles and internal holesof the left and right eccentric sleeves do not share the same center, and half-brasses is installed between the lower end of the connecting bar and the top knife rest.
Description
Technical field
The invention belongs to metal sheet shearing machine tool technical field, be specifically related to the jockey of connecting rod and upper tool post in a kind of hydraulic rolling cut type metal sheet shearing machine.
Background technology
Filed an application by University Of Science and Technology Of Taiyuan and Taiyuan Science And Technology Institute Heavy Industry Science And Technology Co., Ltd, name is called " hydraulic rolling cut type metal sheet shearing machine " and is authorized to, and the patent No. is " ZL 2,006 1 0102208.X ", and its transmission sketch as shown in Figure 1.This patent of invention proposes from the overall structure aspect, wherein connecting rod 3,6 and upper tool post 7 to be connected to bearing pin hinged, as being undertaken hinged by existing routine techniques, though also can produce, but can increase the physical dimension of bearing pin, connecting rod, upper scissor blade knife rest, make the machine construction size huge, weight increases, and investment strengthens.Simultaneously, during shearing between connecting rod and the upper scissor blade knife rest the suffered percussion of half brasses also can increase, influence the service life of half brasses.
Summary of the invention
The object of the invention provides a kind of improved jockey, can overcome the shortcoming that prior art exists effectively.
The present invention is achieved in that and it is characterized in that connecting rod is the fork configuration of " Y " shape, the upper end fork-shaped is hinged by the piston rod of bearing pin and push rod and hydraulic cylinder, the lower end is hinged by bearing pin and upper scissor blade knife rest, it is the eccentric bushing of S that cylindrical and endoporus eccentric throw are installed in the pin shaft hole of connecting rod lower end, and the span of eccentric throw S is 5～8mm.Between connecting rod and upper scissor blade knife rest, half brasses is installed.
Advantage of the present invention and good effect are owing to adopted excentric sleeve, can make bearing pin 13,13 ' the last arc surface of upper semi-circle cylinder and upper scissor blade knife rest 7 pin shaft holes between and half brasses 12,12 of the face of cylinder of connecting rod 3,6 lower ends and upper scissor blade knife rest 7 ' between become no gap and contact, and with the following arc surface generation gap S of the pin shaft hole of upper scissor blade knife rest 7.Like this in the motion process of shearing, bearing pin 13,13 ' only plays the effect that promotes upper scissor blade knife rest weight, do not bear the effect of shearing force, shearing force is born by the face of cylinder of connecting rod 3,6 lower ends, by half brasses 12,12 ' pass to upper scissor blade knife rest 7 to shear.This structural feature can make the physical dimension of connecting rod, bearing pin and upper scissor blade knife rest reduce greatly, when shearing, also can eliminate simultaneously the connecting rod face of cylinder, 3,6 lower end and half brasses 12,12 ' between the gap, reduce the impact of double brasses, improve half brasses 12,12 ' service life (referring to Fig. 3,4).

Among the figure: 1,4-hydraulic cylinder 2,5-push rod 3,6-connecting rod, 7-upper scissor blade knife rest, 8-cutter, 9-guide post 10,10 '-bearing pin 11,11 '-eccentric bushing 12,12 '-half brasses 13,13 '---bearing pin 14,14 '-piston rod 15,15 '-bearing pin S-eccentric throw.
The specific embodiment
As shown in Figure 1, connecting rod 3,6 is symmetrical with being connected of upper scissor blade knife rest 7, and its jockey left and right sides is identical, is that example is illustrated below with the left side:
As shown in Figure 2, connecting rod 3 is " Y " shape structure, and the piston rod 14 and the push rod 2 of its upper end fork-shaped and hydraulic cylinder 1 are hinged, and the lower end is hinged by bearing pin 13 and upper scissor blade knife rest 7.The eccentric bushing 11 that cylindrical and endoporus distance of center circle are S is installed in the pin shaft hole of connecting rod 3 lower ends, and the span of eccentric throw S is 5～8mm (seeing Fig. 3,4,5).In that being installed between connecting rod 3 and the upper scissor blade knife rest 7, half brasses, 12, half brasses 12 are installed in the semicircle cambered surface of upper scissor blade knife rest 7.
Claims (1)
1. the jockey of connecting rod and upper scissor blade knife rest in the hydraulic rolling cut type metal sheet shearing machine, it includes connecting rod, upper scissor blade knife rest and bearing pin.It is characterized in that connecting rod (3,6) is the fork configuration of " Y " shape, the piston rod (14,14 ') and the push rod (2,5) of upper end fork-shaped and hydraulic cylinder (1,4) are hinged, the eccentric bushing that cylindrical and endoporus eccentric throw are S (11,11 ') is installed in the pin shaft hole of lower end, the span of S is 5～8mm, bearing pin (13,13 ') is installed in the eccentric bushing (11,11 '), and be hinged with upper scissor blade knife rest (7), half brasses (12,12 ') is installed between connecting rod (3,6) and upper scissor blade knife rest (7).
