Description
Technical Field
The utility model relates to a single-cylinder plate shearing machine with a rocker arm type mechanical safety bolt structure.
Background
The press machine drives the working mechanism by the motor through the transmission mechanism to apply the process force to the workpiece. The transmission mechanism is a speed reducing mechanism driven by a belt and a gear; the working mechanism comprises a screw mechanism, a crank connecting rod mechanism and a hydraulic cylinder. The presses are classified into three categories, namely screw presses, crank presses and hydraulic presses. Crank presses are also known as mechanical presses.
The screw press has no fixed bottom dead center, and can be used for repeatedly striking and forming larger die forgings, and single striking, continuous striking and inching can be carried out. The striking force is related to the deformation amount of the workpiece, and is small when the deformation is large, and is large when the deformation is small (such as cold striking). In these respects it is similar to a forging hammer. But the striking force is closed by the frame, so the working is stable, the vibration is much smaller than that of a forging hammer, and a large foundation is not needed.
With the wider and wider industries of press machine service, the smaller and smaller household appliance industries, the larger and wider application range of the press machine, and the safety use performance of the press machine is more and more important for people.
The safety bolt prevents the tool rest from sliding down accidentally to generate safety or die accidents during maintenance of the punch press, has a linkage function with the motor start of the punch press, and cannot be started when the safety bolt is taken out for use. The sliding block is formed by welding round steel, and the strength of the sliding block can support the weight of the whole sliding block part, so that the sliding block is heavy and laborious to move.
The utility model comprises the following steps:
the utility model aims to solve the defects in the prior art and provides a single-cylinder plate shearing machine with a rocker arm type mechanical safety bolt structure.
A single-cylinder plate shearing machine with a rocker arm type mechanical safety bolt structure comprises a supporting column, a mounting seat and a rocker arm, wherein the mounting seat is fixed on the side face of a machine body of the plate shearing machine, the rocker arm is hinged to the mounting seat, the supporting column is connected with the rocker arm, and the supporting column rotates between a table top and a sliding block of the plate shearing machine along with the rocker arm when the plate shearing machine is maintained.
Working principle: the safety bolt is placed between the sliding block and the table top during maintenance of the press machine, the sliding block is prevented from sliding downwards outside, damage is caused, but the safety bolt is heavy, and labor is wasted in moving by manpower, so that the support column is driven to move between the sliding block and the table top through the rotation of the rocker arm, and when the press machine is not used, the press machine can be in situ through the rotation of the rocker arm, and labor is saved through the replacement of the rocker arm.
In order to prevent the support column from rotating along with the rocker arm due to shaking when the plate shearing machine works, so that damage is caused, the mounting seat is further provided with a hook, the hook is used for limiting the rocker arm, and the rocker arm is prevented from shifting when the plate shearing machine works.
In order to buffer falling outside the sliding block, the supporting column is of a telescopic structure, and a spring is sleeved on the supporting column.
In order to prevent damage caused by machine operation during maintenance, a safety switch is further arranged on the machine body and used for sensing the supporting column and controlling the motor to be powered off and on, the motor controls the plate shearing machine to work, and when the supporting column leaves the safety switch, the safety switch controls the motor to be powered off so that the machine stops operating.
The beneficial effects are that: compared with the prior art, the utility model drives the support column to rotate between the sliding block and the table top through the rotation of the rocker arm, thus avoiding the manual carrying work and achieving the purpose of quickly and laborsaving moving the safety bolt to the bottom surface of the sliding block. And a safety switch is connected, so that the shearing machine stops working as long as the safety bolt is rotated and swung, and the safety of maintenance personnel and the safety of cutters are ensured.

Detailed Description
The present utility model will be further described in detail with reference to the following examples and drawings for the purpose of enhancing the understanding of the present utility model, which examples are provided for the purpose of illustrating the present utility model only and are not to be construed as limiting the scope of the present utility model.
1-2, a sliding block 1, a supporting column 2, a spring 3, a rocker arm 4, a mounting seat 5 and a hook 6;
a single-cylinder plate shearing machine with a rocker arm 4 type mechanical safety bolt structure comprises a support column 2, a mounting seat 5 and a rocker arm 4, wherein the mounting seat 5 is fixed on the side face of a machine body of the plate shearing machine, the rocker arm 4 is hinged to the mounting seat 5, the support column 2 is connected with the rocker arm 4, when the plate shearing machine is maintained, the support column 2 rotates between a table top of the plate shearing machine and a sliding block 1 along with the rocker arm 4, and particularly, the plate shearing machine comprises the sliding block 1 and a pedestal, an object needing to work is placed on the table top of the pedestal during working, the object is processed through sliding of the sliding block 1, and when the machine is maintained, the support column 2 is driven to rotate between the sliding block 1 and the table top through the rocker arm 4 so as to prevent the sliding block 1 from falling.
