Description
Technical Field
The utility model belongs to the technical field of bending machines, and particularly relates to a noise reduction device for a bending machine.
Background
At present, in the numerical control bending machine in the market, particularly in an outer protection structure equipped for an electric drive bending machine, no effective protection is made for the noise, and only a plurality of covers are manufactured for protection, so that the mechanical safety is ensured. However, for electrically driven bending machines, the screw and the synchronizing wheel (belt) produce a relatively loud "whistling" sound during operation, and noise is also increasingly noticeable, especially at higher operating speeds. High frequency noise can cause discomfort to operators, so it is necessary to design a protection device that can effectively reduce noise to protect operators.
Disclosure of utility model
The utility model aims to provide a noise reduction device for a bending machine, which is used for solving the problems in the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions: a noise reduction device for a bending machine comprises a protective cover main body, a cover plate and suction cotton; the protective cover is characterized in that the protective cover body is buckled above the synchronous wheel of the machine tool, the protective cover body is connected with the side part of the machine tool through a cover plate, and the suction cotton is fixed on the inner side of the protective cover body.
Preferably, the cover plate is perpendicular to the side wall of the shield body and the machine tool side.
Preferably, sound absorbing cotton is also mounted on the inner side of the cover plate.
Preferably, the front part of the protective cover main body is provided with a slot, and the slot is connected with a machine tool.
The beneficial effects of the utility model are as follows: the device can effectively reduce noise transmission through the airtight mode and the mode of increasing sound absorbing cotton, and particularly avoids howling in the high-speed operation of the electric drive bending machine, so that operators can give full play to the speed advantage of the electric drive bending machine when working, and the influence of noise on the operators can be prevented when the working efficiency is improved. The device has great help to improve the working efficiency.

FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a perspective view of another aspect of the present utility model;
Fig. 3 is a schematic view of the present utility model mounted on a bending machine.
Detailed Description
The following detailed description of the utility model refers to the accompanying drawings and preferred embodiments.
As shown in fig. 1 to 3, a noise reduction device for a bending machine includes a shield main body 1, suction cotton 2, and a cover plate 3; the protective cover is characterized in that the protective cover body is buckled above the synchronous wheel of the machine tool 4, the protective cover body is connected with the side part of the machine tool through a cover plate, and the suction cotton is fixed on the inner side of the protective cover body. Noise mainly is produced by lead screw and synchronizing wheel (area) during operation, and before this protection casing of installation, sound transmission is divergently, and operating personnel direct contact noise has very big influence to operating personnel's somatosensory. After the protective cover is added, the main body 1 fully covers the upper part of the synchronous wheel to avoid the divergence of sound, meanwhile, the side edge design cover plate 3 fills the gap between the protective cover main body 1 and the machine tool 4, and at the moment, the protective cover main body 1 and the machine tool 4 completely cover the lead screw and the synchronous wheel (belt), thereby effectively avoiding the propagation of noise. Meanwhile, the sound-absorbing cotton 2 is added in the protective cover main body 1, and the sound-absorbing cotton 2 is fixed in the main body 1 in a double-sided adhesive bonding mode. After the sound-absorbing cotton 2 is added, the transmission of sharp noise can be effectively reduced, so that the comfort of operators is improved.
The cover plate is perpendicular to the side wall of the protective cover body and the side part of the machine tool. Noise is prevented from coming out of the machine tool side.
The inner side of the cover plate is also provided with sound absorbing cotton. Surrounding the bending machine, and further reducing noise.
In order to be tightly fixed with the machine tool, the front part of the protective cover main body is provided with a slot 5 which is connected with the machine tool.
The device combines sound insulation and sound absorption through the sealed structure and the mode of adding sound absorption cotton in the cover, thereby effectively reducing noise. The totally sealed structure can avoid noise to leak outside through the gap, and inhale the reflection that the sound cotton can effectively absorption noise in the panel beating guard shield and form "draw in sound" effect in turn, increase lathe noise on the contrary. The noise can be effectively reduced by 5-7 dB after the noise is effectively combined, the numerical control is controlled in the national standard, the howling sound can be reduced by adding the sound-absorbing cotton-added protective cover, the body feeling of an operator is greatly improved, the noise pollution of the operator is avoided, the mood of the operator is kept, and the working efficiency is improved.
It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be comprehended within the scope of the present utility model.
