Noise Reduction Engineering of Precision Press

Reverberation time refers to the indoor sound to a stable state, precision punching sound source to stop the sound after the sound of the room in the recurrent reflection by the wall absorption, the average acoustic energy density Down to the original value of one millionth of the time. The longer the reverberation time is, the more the noise is reflected in the workshop, the slower the energy decay rate. In the same sound source, the reverberation time is longer than the reverberation time.

2, the choice of precision punching sound-absorbing material: a total of five parts sound insulation board, noise through perforated plate holes into the sound-absorbing cotton, a part of the glass wool through the vibration of energy into heat energy consumption, the other part of the outer layer of steel isolated , To share the purpose of smoking. (1) The thickness of the outer 2mm steel plate, from the noise and support role Dished Head Punching Machine, and is the sound-absorbing panel of the outer surface. (2) the middle part of the sound-absorbing panel for the sound-absorbing material, made of glass wool products, for the absorption of sound energy, noise is a major component of the material. (3) fiberboard paste in the sound-absorbing cotton outside, to prevent the sound-absorbing cotton falling. (4) Transparent film attached to the sound-absorbing cotton on both sides, since the moisture-proof and prevent sound-absorbing cotton wire from the inner perforation plate perforation in the role of the net steel punch. 3, sound-absorbing panel sealing treatment: As the entire production line closed processing is a number of small sound-absorbing panels stitched together into a closed body, so in order to ensure precision punching noise reduction effect, in the design and manufacturing need to control the various sound-absorbing panels between the Clearance, generally 1 ~ 2mm.

In order to minimize the effect of noises passing through these gaps to effect noise reduction, sealants are often used for gap seals. 4, ventilation: the operation of the heat generated by the device itself, coupled with the sound-absorbing material with glass wool insulation properties, the production line within the closed temperature is often higher than the external 3 ~ 5 ℃. In the implementation of noise reduction projects, usually in the noise ceiling installation of exhaust fans, take away the hot air enclosed space, so that the formation of negative pressure inside, the external air can flow through the noise wall inside. In the selection of exhaust fan selection of low noise fan so as not to affect the noise reduction effect. 5, the lighting treatment: the closure of the project after the implementation of the internal and external lighting equipment, cut off, so the need to increase the enclosed lighting system. In order to ensure the production and maintenance of equipment required for lighting drill machine, design illumination of 500 lumens or more. Closed body lighting system to separate wiring, independent switch, to ensure ease of use and does not affect the original power supply system. In addition, in order to prevent a sudden power outage in the enclosed body in the installation of emergency lighting system to ensure the safety of equipment and personnel.

Universal user response punch quality is not the most important price problem

To deal with the user throughout the punch analysis, it should be very simple, ordinary punch the biggest bad place in that place, that is, its quiet function, a prudent may lead to sacrifices, then, for this, pneumatic What are the benefits of punching? The following are some of the benefits of pneumatic punching.

Pneumatic punch, brake mode pneumatic syringe, the key punching power, from the motor to take the lead in the flywheel, flywheel driven crankshaft, and the momentum occurred. Safety, pneumatic punch press than the traditional safety performance in the above should be high; compact, pneumatic punch press than the traditional high precision; high and low mode compared to traditional punching machine for convenience. Speed, pneumatic punch compared to faster; pneumatic punch with a cylinder, the demand for gas, the traditional do not have; price, pneumatic punch press than the traditional price to be higher.

Ordinary punch, is the selection of traditional braking methods, more common for the clumsy key brake, the main road pressure power, driven by the motor flywheel, flywheel driven crankshaft, and the resulting momentum. Ordinary punch press, also known as press, is a more traditional stamping process of mechanical processing. Such a machine can achieve savings in energy and material, and the efficiency is relatively low compared to the pneumatic punch. The ability to manipulate the request is not high, so there are some security risks there are risks.

Punching machine is the general machinery of the stamping industry. It is suitable for punching, blanking, bending, stretching and other cold stamping (not used for pressing and printing work). It can be semi-spontaneous or fully self- Equipped with photoelectric love, can be minimized occupational damage.

Punch security by the light-emitting device, by the light, the controller, signal cables and control cables of five parts.

Light emitted by the light emitter directly to the receiver, resulting in protective light curtain. When the light curtain is obscured, the receiver generates a shading signal, the signal cable is transmitted to the controller, the controller will contain the signal to produce a control signal to control the machine brake control circuit or other building alarm installation, to achieve Machine parking or safety alarm.
Protection of the length of 0-2000mm, properly manipulated within 2 meters of the machine table or partial protection area.

Protection height due to specifications and willow, from 100mm to 1240mm are products to the case.

Difficulties of the optical axis is divided into 20mm, 30mm, 40mm three, parting force of different 30mm, 40mm, 50mm.

Precision presses on the radio-type arrangement, small and beautiful, easy to install.

The error between punch presses is caused by what factors

Die punch stamping process has a certain error, the error depends on what factors? Let us learn together:

1, the size of the gap, the average degree: deep drawing, bending, flanging and other sheet metal forming parts usually need to cut out a blank tablet, has also formed punching, cutting a single finished pieces. Homework, blanking, including common punching, cutting, dressing, etc., for each sheet metal stamping parts are necessary. So the blanking gap hedge determines the dimensional accuracy of the contour. Punch small and average blanking gap, punching punch size can be made to obtain a higher accuracy. For deep drawing, bending forming molds, such as a large gap will increase the size of the punch mouth size error and rebound. Clearance is not a common cause of increased punching burrs and uneven edges due to uneven wear.

2, the elastic deformation of punch equipment: in the stamping process, the punch load after a certain degree of elastic deformation. According to the burst pressure change and significant direction of the size of the deformation, but for stamping parts, mainly for stamping, embossing, with volume stamping flat, bump, pressure wave, broken, heading, flange, upsetting, beating, The deep throat is made in the form of workmanship in the form of stamping, a remarkable effect in its dimensional precision stamping.

3. Dimensional accuracy of the punch material, structure, dimensions and material thickness, the dimensions of the blanking gap and the decisive effect of cutting on its average degree. Different types of punching process, different materials with different thickness of the material, one of the six customs clearance, press great difference in punching accuracy. Uniform modulus m = 0,2 mm thick 34, with hole H62 brass pieces of gear in the middle of the compound stamping die, when the gap C = 0,5% ton (unilateral) Of the IT7 level, salt pieces of flat arch bending, up to 89 of the blunt verticality, 5 degrees, the surface roughness Ra value is 0,2 micron stamping size; with ordinary composite die manufacturing, the gap C = T (unilateral) 5%, the initial error of the punch, the punch of the initial precision stamping die for a T9,12 Ra value, 5 microns, 0 burr height of the rough cutting surface roughness, 10 mm; stamping die is still a continuous system , The initial punching precision IT11 blunt edge is thicker. Under normal circumstances, hot stamping material and T thickness of the main basis for selection blanking gap. Once the open punch gap is selected to determine the constant error of the planar dimensions of the body of the punch; the stiffness of the salt piece structure and the three-dimensional shape affect its accuracy.

Different types of drilling structures are different, and thus the thickness of the shared material and manufacturing precision stamping differences, press punching constant error is also different.
