Description

Closed noise reduction mechanism of press upper beam

Technical field

The invention belongs to the field of noise reduction equipment, and particularly relates to a closed noise reduction device for a press upper beam.

Background technique

In the stamping production process of automobile shells, there has always been a problem that noise interferes with production. The stamping production line is generally an open production line, so its sound insulation measures are particularly important. Generally speaking, the noise of the stamping production line is usually caused by the collision between the stamping machine and the stamping part. During the work of the stamping machine, it punches vertically downward and contacts the stamping part. The stamping machine and the stamping Various forms of vibration are generated between the pieces, and the vibration generates sound waves. Therefore, this sound wave is not a one-way propagation sound wave, and it needs to perform a full range of noise reduction processing.

In the published existing literature, the Chinese utility model patent with the announcement number CN201089982Y discloses a fully enclosed noise reduction device for automobile stamping production lines. This fully enclosed noise reduction device for stamping lines is installed on the ground and is suitable for stamping production lines. The closing of the lower part of the upper beam of the press can generally suppress the noise generated by the stamping from spreading from the ground, but the top of the press lacks a device to suppress the propagation of noise.

In view of the above problems, the present invention proposes a closed noise reduction device for the press upper beam.

The purpose of the steel frame is to provide support and fixation for the openable closing device, fixed sound insulation board, and various auxiliary devices of the mechanism. According to customer requirements or specific conditions, the steel frame is connected to the top of the fully enclosed noise reduction equipment or fixed to the beam platform of the press.

The openable closing device at least includes a closing member, and the closing member is connected to the power source.

The power source of the openable closing device is a motor, a hydraulic power source, a pneumatic power source or a manual.

The closing member is provided on the top of the support frame.

The controller uses a single chip microcomputer or a PLC, and the controller is connected to the motor and controls the movement of the motor. This is a content well known to those skilled in the art and will not be repeated here.

The fixed sound insulation board is various boards including a sound absorption board but not limited to a sound absorption board. The sound absorbing plate includes a shell and a sandwich layer provided inside the shell, and the shell is closed by using a punching plate. The sound-absorbing board is made of steel plate and sheet metal by bending and welding, and the interior is filled with an attractive material as an interlayer. The back of the housing is closed with a punching plate; other boards besides the sound-absorbing board can be various metals such as organic glass and polycarbonate Or a structure made of non-metallic materials.

The fixed sound insulation board is used as the outer surface of the upper beam of the press to close the noise reduction mechanism, and is fixed on the steel frame to close the area other than the roller blind device, so that the mechanism closes the upper beam of the press.

The auxiliary device includes a ventilation device and a lighting device, and the ventilation device and the lighting device are fixed to the support structure.
