Abstract

The aim of the utility model is to provide a pendulum shear machine provided with a spring cylinder overhead. The spring cylinder pendulum shear machine comprises a machine rack, a shear rack, a hydraulic cylinder and a spring cylinder. Especially at least one spring cylinder is arranged on the upper part of the shear rack; a folder and a pistol rod of the spring cylinder are respectively connected actively with the machine rack and the shear rack through a first gemel and a second gemel. The technical effects of the utility model is that the pendulum typed guillotine shear has fast returning speed; the shearing depth of plate is long; the model is provided with higher cost performance and shearing speed and has low energy consumption, stable working and is durable, thus providing an ideal guillotine shear machinery.

Description

Spring cylinder pendulum shearing machine

Technical field

The utility model relates to a kind of plate shearing machine, relates in particular to a kind of swing-type plate shears.

Background technology

Along with China's rapid development of economy, the installing of most of building, automobile, household electrical appliances etc. all need to use in a large number the sheet metal material, just need the equipment of a large amount of shears.Domesticly in recent years a large amount of sheet metal processing enterprises also occurs, but because production efficiency is low and the energy consumption height, can not satisfy both at home and abroad production requirement plate shearing machine high efficiency, high-quality, low energy consumption.Make a general survey of domestic swing-type plate shears production industry, the backhaul mode of the knife rest that pendulum is cut is roughly divided three classes, but shortcoming is respectively arranged, and is described as follows:

(1) oil cylinder backhaul: though aspect of performance is better, the cost of manufacturing hydraulic cylinder compares higher, adds the outfit of hydraulic valve, conduit under fluid pressure, electric elements, and the manufacturing cost that can be directed at whole swing-type plate shears is higher.

(2) nitrogen cylinder backhaul: 1) the backhaul slow motion of nitrogen cylinder; 2) the nitrogen cylinder occurred the apical grafting place and walks and fly out, and caused casualties easily; 3) the nitrogen cylinder use of a specified duration, often leak air existing to; 4) unload gas or air pressure is low, need the tired operator of labor add nitrogen; 5) some little enterprises buy the nitrogen inconvenience, and the price height; 6) the machine next door is placed nitrogen cylinder and is taken the place; 7) in assembling process, need a large amount of mistake feed channel, to the cost up of manufacturing enterprise; 8) cylinder or the pipeline main point of leaking gas bothers after sale personnel to go to handle.

(3) lower spring cylinder backhaul: 1) spring cylinder be fixed on knife rest below: the slide of spring cylinder is fixed on the frame, and piston rod only just contacts in the process that knife rest presses down with knife rest, so the piston rod in the spring cylinder is easy to be driven and deflection by the frictional force of the relative translation between knife rest and the piston rod masthead, make that spring stress in the spring cylinder is inhomogeneous and be easy to fatigue failure in addition with the slide wall friction, so the spring in the spring cylinder needs often to change; 2) cost of spring is higher relatively, safeguards also relatively difficulty, and under the situation that spring must regularly replace, its cost performance is lower; 3) the spring cylinder opening speed is very fast, need not the energy, can improve working (machining) efficiency widely, for processing enterprise saves time and cost.

Summary of the invention

The purpose of this utility model provides the pendulum shearing machine of putting on a kind of spring cylinder.

For achieving the above object, the utility model has been taked following technical scheme:

Spring cylinder pendulum shearing machine comprises frame, knife rest, hydraulic cylinder and spring cylinder, especially, has at least one spring cylinder to be arranged on the top of knife rest, and the slide of spring cylinder and piston rod flexibly connect by first hinge and second hinge and frame and knife rest respectively.

To above technical scheme, can also do following replenishing or extension:

First hinge is arranged on the bottom of slide.

Second hinge is arranged on the masthead of piston rod.

Be connected by the hinge seat that can on knife rest, adjust link position between second hinge and the knife rest.

Below operation principle of the present utility model is described:

The slide end and the tailpiece of the piston rod of spring cylinder all are provided with hinge, so what can guarantee spring cylinder is stressed always along axis direction wherein, and deflection can not take place, and the piston rod of spring cylinder is being connected with knife rest all the time, do not have shock problem in the course of work, more than 2 can guarantee that spring cylinder has longer service life.Spring cylinder is arranged on the top of knife rest, can be the knife rest below and save the charging space, thereby make the pendulum shearing machine can cut out darker plate length.

Technique effect of the present utility model is: this swing-type plate shears opening speed is fast, and it is long to cut out slab depth, have than high performance-price ratio and shear rate, and energy consumption is low, working stability is durable, for the user provides a desirable shear machinery.

The specific embodiment

Below in conjunction with drawings and Examples the utility model content is described further.

As shown in Figure 1, be the structure chart of the utility model under wait state, the pendulum shearing machine comprises frame 1, knife rest 2 and spring cylinder 3.Wherein, knife rest 2 can rotate on frame 1 by turning cylinder 4.Hydraulic cylinder 5 is fixed on the frame 1, and its push arm 6 is installed on the knife rest 2, promotes knife rest 2 and in the mode of swing plate is cut out.Spring cylinder 3 is arranged on the top of knife rest 2, and the slide 7 on it flexibly connects by first hinge 8 and frame 1; After piston rod 9 on it flexibly connected by second hinge 10 and hinge seat 11, hinge seat 11 was fixed on the knife rest 2 again.

At ordinary times, knife rest 2 has the pretightning force of a compression to spring cylinder 3 under the effect of deadweight.As shown in Figure 2, when shearing plate, the push arm 6 of hydraulic cylinder 5 overcomes the elastic force of spring cylinder 3, and plate is depressed and sheared to knife rest 2.After shearing is finished, hydraulic cylinder 5 releases, the piston rod 9 of spring cylinder 3 overcomes the oil return power of hydraulic cylinder 5 and the gravity of knife rest 2, makes knife rest 2 quick returns, recovers duty as shown in Figure 1.

Being fixedly connected as be relatively fixed between hinge seat 11 and the knife rest 2 is connected, and regulates the installation site of hinge seat on knife rest 2 during installation, can make spring cylinder 3 obtain different pretightning forces.The regulatory function of this pretightning force can metal fatigue occur at spring cylinder 3, when elastic force presents decline, makes the usefulness of stretch compensation.
