[0027] This application provides a discharge rack, a punch press, and a stamping system to solve the problem of noise pollution caused by the transmission of noise from the soundproof room during discharge when the existing discharge rack discharges material. The following description is in conjunction with the accompanying drawings.

[0028] The discharge rack provided in this embodiment is applicable to a stamping system. The stamping system includes a punch press 3 and a soundproof enclosure 2. The soundproof enclosure 2 forms a receiving space 21 and a discharge port 22. The punch press 3 is disposed within the receiving space 21. Please refer to [link to relevant documentation]. Figs. 1 to 3The discharge rack includes a turntable 1, which is rotatably mounted at the discharge port 22. The turntable 1 has a transfer station 11, which receives the workpiece output by the punch press 3 inside the discharge port 22 and rotates with the turntable 1 to the outside of the discharge port 22 for discharge. The transfer station 11 is equipped with sound insulation components around its perimeter. When the transfer station 11 rotates to the inside of the discharge port 22, the sound insulation components block the discharge port 22. The inside of the discharge port 22 is the interior of the soundproof room 2, and the outside of the discharge port 22 is the exterior of the soundproof room 2.

[0029] The discharge rack provided in this embodiment has a soundproof component on the periphery of the transfer station 11 of the turntable 1. When the transfer station 11 rotates to the inside of the discharge port 22 to receive the workpiece output by the punch press 3, the soundproof component blocks the discharge port 22. Therefore, the impact sound when the workpiece moves to the transfer station 11 and other sounds inside the soundproof room 2 are blocked by the soundproof component, preventing noise from the soundproof room 2 from being transmitted from the discharge port 22, thereby improving the soundproofing effect of the soundproof room 2.

[0030] Optionally, the transfer station 11 includes multiple stations spaced circumferentially along the turntable 1, and each transfer station 11 is equipped with a sound insulation component.

[0031] By setting multiple transfer stations 11 on the turntable 1, the transfer efficiency of the discharge rack is improved. At the same time, each transfer station 11 is equipped with a corresponding sound insulation component. That is, when each transfer station 11 rotates to the inside of the discharge port 22 to receive the workpiece output by the punch press 3, there is a corresponding sound insulation component that can block the impact sound when the workpiece moves to the transfer station 11 and other sounds inside the soundproof room 2, so as to avoid the noise of the soundproof room 2 affecting the external working environment.

[0032] Optionally, the sound insulation component includes two first sound insulation panels 12, each extending radially from the rotation center of the turntable 1, with a transfer station 11 sandwiched between the two first sound insulation panels 12; the soundproof room 2 includes a pair of side walls surrounding the discharge port 22 and located on both sides of the turntable 1. When the transfer station 11 rotates to the inside of the discharge port 22, the corresponding two first sound insulation panels 12 abut against one of the side walls respectively. That is, by the cooperation and abutment between the pair of first sound insulation panels 12 and the pair of side walls, the transmission of noise is blocked in the horizontal direction.

[0033] Optionally, multiple transfer stations 11 are evenly distributed along the circumference of the turntable 1, with adjacent transfer stations 11 sharing a first sound insulation panel 12, thereby saving the cost of sound insulation components and improving material utilization efficiency. Simultaneously, the even distribution of multiple transfer stations 11 means that the turntable 1 can rotate by the same angle each time, allowing each transfer station 11 to operate according to a fixed stroke, simplifying the control algorithm of the turntable 1. The drive structure of the turntable 1 is not further limited here. In some examples, the discharge rack also includes a drive motor for driving the turntable 1 to rotate.

[0034] Optionally, the soundproof enclosure 2 also includes a top wall surrounding the discharge port 22 and located at the top of the turntable 1; the soundproofing component also includes a second soundproofing panel, which is connected between two first soundproofing panels 12 and located at the end of the two first soundproofing panels 12 away from the turntable 1, with the second soundproofing panel close to the top wall. By setting the second soundproofing panel, the transmission of noise is blocked at the top of the turntable 1 in the vertical direction, further improving the soundproofing effect of the soundproofing component.

[0035] Furthermore, the second soundproofing panel can be disc-shaped, for example, the same shape and size as the turntable 1, and connected to the end of the plurality of first soundproofing panels 12 away from the turntable 1.

[0036] In some examples, please refer to Fig. 1 The turntable 1 has two transfer stations 11, which are evenly distributed. Each transfer station 11 is a semicircle. The rotation center of the turntable 1 falls within the discharge port 22. Two first sound insulation boards 12 are provided between the two transfer stations 11. The diameter of the two first sound insulation boards 12 is the same as that of the turntable 1. The first sound insulation boards 12 are close to the top wall of the discharge port 22 but do not interfere with each other. At this time, there is no need to set a second sound insulation board to save the cost of the second sound insulation board.

[0037] In other examples, please refer to Fig. 2 The turntable 1 has three transfer stations 11, which are evenly distributed. Each transfer station 11 is a fan-shaped structure one-third the size of the turntable 1. Three first sound insulation panels 12 are provided on the turntable 1 to separate the three transfer stations 11. The three first sound insulation panels 12 are evenly distributed along the circumference of the turntable 1. The specific location of the turntable 1 is not further limited here. The rotation center of the turntable 1 can be inside the soundproof room 2. In this case, when the turntable 1 rotates, there are more transfer stations 11 located inside the soundproof room 2 at the same time. Alternatively, the rotation center of the turntable 1 can be outside the soundproof room 2. In this case, when the turntable 1 rotates, there are more transfer stations 11 located outside the soundproof room 2 at the same time.

[0038] This application embodiment also provides a punch press 3, suitable for a stamping system. The stamping system includes a soundproof chamber 2, which forms a receiving space 21 and a discharge port 22. The punch press 3 is disposed within the receiving space 21 and includes a discharge rack as described above. The discharge rack includes a turntable 1, which is rotatably disposed at the discharge port 22. The turntable 1 is provided with a transfer station 11, which is used to receive the workpiece output by the punch press 3 inside the discharge port 22 and then rotate with the turntable 1 to the outside of the discharge port 22 for discharge. Soundproofing components are provided around the transfer station 11. When the transfer station 11 rotates to the inside of the discharge port 22, the soundproofing components block the discharge port 22.

[0039] This application embodiment also provides a stamping system, including a soundproof chamber 2, a punch press 3, and a discharge rack as described above. The soundproof chamber 2 forms a receiving space 21 and a discharge port 22; the punch press 3 is disposed within the receiving space 21. The discharge rack includes a turntable 1, which is rotatably disposed at the discharge port 22. The turntable 1 is provided with a transfer station 11, which is used to receive the workpiece output by the punch press 3 inside the discharge port 22 and then rotate with the turntable 1 to the outside of the discharge port 22 for discharge; the transfer station 11 is provided with soundproofing components on its periphery, and when the transfer station 11 rotates to the inside of the discharge port 22, the soundproofing components block the discharge port 22.

[0040] By cooperating with the sound insulation components of the discharge rack and the discharge port 22 of the soundproof room 2, the sound insulation effect of the stamping system is improved and the noise pollution of the stamping system is reduced.

[0041] Optionally, the soundproof room 2 includes a pair of steel plate layers and a sound insulation layer sandwiched between the pair of steel plate layers. The sound insulation layer is made of one or more of the following materials: sound insulation cotton, damping paste, and aluminum foam. The steel plate layers are made of steel plates.

[0042] In some examples, the sound insulation layer can be made of sound insulation cotton; in other examples, the sound insulation layer can be made of damping paste; in still other examples, the sound insulation layer can be made of aluminum foam; and in yet another example, the sound insulation layer can be made of a mixture of sound insulation cotton, damping paste, and aluminum foam.

[0043] The sound insulation capability of the walls of the soundproof room 2 is further improved by setting a sound insulation layer between a pair of steel plate layers. In some examples, the thickness of the steel plate layer can be 1 mm and the thickness of the sound insulation layer can be 10 mm; in other examples, the thickness of the steel plate layer can be 2 mm and the thickness of the sound insulation layer can be 8 mm.

[0044] Optionally, a sealing strip can be installed at the joint between the steel plate layer and the sound insulation layer.

[0045] Optionally, an observation window can be installed on the side wall of the soundproof room 2. The observation window is made of transparent soundproof material to observe the operation inside the soundproof room 2. The outer perimeter of the observation window can be surrounded by a flange and sealing strip to prevent sound leakage at the connection between the observation window and the steel plate layer, thereby improving the airtightness of the soundproof room 2. For example, sound absorbers 23 can be installed on both the top and side walls of the soundproof room 2 to achieve sound field coverage inside the soundproof room 2, while also improving the flame retardant effect.

[0046] Optionally, the inner wall of the soundproof room 2 is provided with a sound absorber 23, which includes a perforated metal plate and fiberglass cloth located within the perforated metal plate. In some examples, the perforation rate of the perforated metal plate can be greater than 30%, such as 31%, 40%, 60%, etc. By setting the sound absorber 23, noise in the soundproof room 2 is absorbed, and reverberation energy is reduced.

[0047] Optionally, an L-shaped aluminum alloy frame can be welded to the inner wall of the soundproof room 2, and the sound absorber 23 is suspended on the L-shaped aluminum alloy frame by hooks.

[0048] Optionally, please refer to Fig. 3 (The discharge rack is not shown). The stamping system provided in this embodiment also includes a concrete base 24, on which the punch press 3 is mounted. A vibration isolation groove 25 is provided between the concrete base 24 and the ground 4. Exemplarily, the punch press 3 and the concrete base 24 are connected by bolts with rubber damping sleeves. The concrete base 24 is made of inert concrete. The inert concrete base 24 supports the punch press 3, and the vibration isolation groove 25 surrounds the edge of the concrete base 24, cutting off the solid-borne sound propagation path of vibration to the ground 4. The bolt connection achieves rigid fixation between the punch press 3 and the concrete base 24 and initial vibration attenuation.

[0049] As an alternative implementation, a magnetic levitation device can be used to replace the isolation trench 25 and the concrete base 24 to cut off the transmission of vibration.

[0050] Optionally, the seismic isolation trench 25 can be filled with foam board to further improve the seismic isolation effect of the seismic isolation trench 25.

[0051] Optionally, the stamping system also includes a ventilation module equipped with a silencer. For example, a silencer is positioned at the bottom of the air inlet of the ventilation module, and silencers are positioned diagonally at the top of the air outlet. Furthermore, the inner wall of the ventilation duct of the ventilation module is lined with sound-absorbing felt, and a rubber flexible connection is provided between the fan and the ventilation duct. This rubber flexible connection weakens the transmission of fan vibration, ensuring noise reduction while ensuring air exchange. The silencer can be connected to the ventilation duct via a flange.

[0052] The stamping system provided in this application embodiment increases the overall noise reduction of the soundproof room 2 by more than three times through the sound absorber 23, the sound insulation layer material of the soundproof room 2, the noise reduction setting of the ventilation module, the rigid vibration isolation of the concrete base 24, and the sound insulation components of the discharge rack, thereby extending the equipment life and optimizing the working environment.

[0053] In some examples, the noise reduction capability of the stamping system provided in this application embodiment is improved from the existing 10 dB to 15 dB to more than 30 dB, which greatly improves the sound insulation and noise reduction capability.

[0054] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
