Abstract
The utility model relates to a ball-and-socket type connecting device for a shearing cylinder and a shearing plate for a crocodile-type scrap shearing machine. The connecting device comprises a shearing plate and a shearing cylinder, wherein, an shaft seat is arranged on the shearing cylinder, a spherical washer is connected with the shearing plate, a ball joint type piston rod of the shearing cylinder is connected with the spherical washer through a clip key and a bolt, the spherical washer is provided with an oil duct, and the oil duct is communicated with an oil cup. All the parts are assembled together to from a spherical universal joint type connecting form. The guide plate is worn and the gap is enlarged under the action of the horizontal shearing component during the working process of the shearing machine, so that the torque is generated, and the device can perform spherical displacement and automatic compensation at the same time during the process of connecting the center shift of the oil cylinder to protect the piston of the shearing oil cylinder form being distorted and broken off.
Description
Technical field
The utility model relates to steel scrap, and processing regenerated to utilize shearing force in the apparatus field be jockey between the shearing oil cylinder of the various crocodile formula of 360～3500kN steel scrap cutting machine and the shearing crocodile plate (abbreviation shear) that cutter is installed.
Background technology
The shear cylinder of crocodile formula steel scrap cutting machine and the traditional jockey between the shear be adopt connector earlier with screw thread be connected with shear plug-in mounting bearing pin and axle sleeve again after shearing oil cylinder piston bar is connected, and prevent that with outer card plate bearing pin from rotating.
This traditional bindiny mechanism weak point is to conduct the component genus in the horizontal direction to be rigidly connected, can't the compensatory shear machine horizontal component during because of work cause between the guide plate wearing clearance to increase to produce moment of torsion and make the horizontal displacement at connection center, and cause the shear cylinder piston rod to be turned round flexible distortion even fracture.Because connector and piston rod employing are threaded, stressed rear thread is yielding, causes the repair demolition difficulty in addition.
Summary of the invention
The purpose of this utility model provides a kind of shear cylinder that makes and can be connected reliably with shear; and the compensatory shear horizontal component increases the guide plate wearing clearance and produces the displacement that moment of torsion causes connecting the center, crocodile formula steel scrap cutting machine shear cylinder and the shear ball-and-socket hinge style jockey that can protect shear cylinder not flexural deformation of piston rod again or fracture simultaneously automatically.
The purpose of this utility model is achieved in that a kind of crocodile formula steel scrap cutting machine shear cylinder and shear ball-and-socket hinge style jockey, comprise shear and shear cylinder, shear cylinder is provided with axle bed, ball ring is connected with shear, the bulb type piston rod of shear cylinder is connected with ball ring with gland and bolt by the card key, ball ring is provided with oil duct, and oil duct communicates with lubricating cup.
Crocodile formula steel scrap cutting machine shear cylinder that the utility model provides and shear ball-and-socket hinge style jockey; connect by parts such as ball-type piston rods between shear cylinder and the shear plate; when guaranteeing shear cylinder and shear can be connected reliably; can make the increase of guide plate wearing clearance produce the displacement that moment of torsion causes connecting the center by automatic compensatory shear horizontal component by the ball-type piston rod, the while can be protected shear cylinder not flexural deformation of piston rod again or fracture.With design on the ball ring that bulb type piston rod cooperates oil duct is arranged, oil duct communicates with lubricating cup, has ensured lubricating between piston rod bulb and the ball ring sphere.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a Facad structure schematic diagram of the present utility model.
Fig. 2 is a working state schematic representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises shear 1 and shear cylinder 3, and shear cylinder 3 is provided with axle bed 2, ball ring 6 is connected with shear 1, the bulb type piston rod 9 of shear cylinder 3 is connected with ball ring 6 with gland 8 and bolt 10 by card key 7, and ball ring 6 is provided with oil duct 5, and oil duct 5 communicates with lubricating cup 4.
Duty of the present utility model is as shown in Figure 2: horizontal component X and moment of torsion Y's cause shear cylinder 3 axis and shear 1 symmetrical center line formation drift angle α because shear 1 is subjected to; the gimbal suspension that formation ball-and-socket hinge styles such as bulb type piston rod 9 are connected to form can produce spherical displacement and compensate because of the effect of level of shear component, protection shear cylinder not flexural deformation of piston rod or fracture.Can be bulb type piston rod 9 to provide lubricated by lubricating cup 4 and oil duct 5 with ball ring 6.
