Description

Technical Field

[0001] This utility model relates to the field of boiler silencer manufacturing technology, and in particular to a limiting mechanism for rolling perforated plates for silencers. Background Technology

[0002] The perforated plate of the boiler tail-end silencer is the core noise reduction component. By adopting small-hole injection silencing technology, the high-frequency noise of high-speed airflow is converted into ultrasonic noise through a porous structure. At the same time, the impedance composite structure is used to further attenuate mid- and low-frequency noise, thus achieving wide-band noise reduction.

[0003] The perforated tube of the boiler tail-end silencer is mainly made by rolling and welding perforated plates. During the rolling process, the position of the existing perforated plates needs to be manually adjusted. The lack of necessary adjustment references and pressure leads to the risk of tilting of the rolled steel plate, resulting in misalignment of the weld and misalignment at the end.

The first sleeve is fitted onto the top of the support frame, and the first knob is threadedly connected to the bottom of the first sleeve. The connecting frame is fixedly disposed on the top of one end of the first sleeve. The backing plate is snapped onto the outside of the connecting frame, and the screw is fixedly disposed on the back of the backing plate. The pressure assembly includes a second sleeve, a second knob, a mounting plate, a guide tube, a telescopic rod, a pusher, a spring, and a pressure roller. The second sleeve is movably connected to the top of the support frame, and the second knob is threadedly connected to the bottom of the second sleeve. The mounting plate is fixedly disposed on the top of one end of the second sleeve. The guide tube is welded and fixed to the outside of the mounting plate. The telescopic rod is snapped into the guide tube. The pusher is fixedly disposed at the tail end of the telescopic rod. The spring is fitted onto the outside of the telescopic rod, and the pressure roller is fixedly disposed at the top of the telescopic rod.

[0006] In a preferred embodiment of the present invention, one end of the screw passes through and extends to the outside of one side of the connecting frame, the surface of the connecting frame is provided with an oblong hole that mates with the screw, and the surface of the screw is provided with a locking nut by means of threads; The height of the backing plate can be adjusted by adjusting the height of the screw within the connecting frame, ensuring that the backing plate is always in contact with one end of the rolled perforated plate.

[0014] like Figure 1-3 The illustrated limiting mechanism for rolling a perforated plate for a muffler includes a support frame 1, a plate rolling machine 2 mounted on top of the support frame 1, a support assembly 3, and a pressure assembly 4 mounted on top of the support frame 1. The support assembly 3 includes a first sleeve 31, a connecting frame 32, a backing plate 33, a screw 34, and a first knob 35. The first sleeve 31 is fitted onto the top of the support frame 1, and the first knob 35 is threaded to the bottom of the first sleeve 31. The connecting frame 32 is fixedly mounted on the top of one end of the first sleeve 31. The backing plate 33 is engaged with the outside of the connecting frame 32, and the screw 34 is fixedly mounted on the back of the backing plate 33. The pressure assembly 4... It includes a second sleeve 41, a second knob 42, a mounting plate 43, a guide tube 44, a telescopic rod 45, a pusher frame 46, a spring 47, and a pressure roller 48. The second sleeve 41 is movably connected to the top of the support frame 1. The second knob 42 is threadedly connected to the bottom of the second sleeve 41. The mounting plate 43 is fixedly installed at the top of one end of the second sleeve 41. The guide tube 44 is welded and fixed to the outside of the mounting plate 43. The telescopic rod 45 is inserted into the guide tube 44. The pusher frame 46 is fixedly installed at the tail end of the telescopic rod 45. The spring 47 is sleeved on the outside of the telescopic rod 45. The pressure roller 48 is fixedly installed at the top of the telescopic rod 45.

[0015] Specifically, one end of the screw 34 passes through and extends to the outside of one side of the connecting frame 32. The surface of the connecting frame 32 is provided with an oblong hole that mates with the screw 34. A locking nut is threaded onto the surface of the screw 34. One end of the first knob 35 passes through and extends to the inner bottom of the first sleeve 31. One end of the second knob 42 passes through and extends to the inner bottom of the second sleeve 41. The tops of the first knob 35 and the second knob 42 are in contact with the inner top of the support frame 1. The pressure roller 48 is movably connected through the pressure roller frame. The spring 47 is located between one end of the guide tube 44 and the pressure roller frame on the back of the pressure roller 48. The bottom of the back plate 33 and the bottom of the mounting plate 43 are provided with slots that mate with the rolling roller of the rolling machine 2.

[0016] In this embodiment, the position of the support component 3 is first adjusted according to the required size of the perforated plate. After loosening the first knob 35, the first sleeve 31 can slide on the top of the support frame 1. After sliding to the appropriate position, the first knob 35 is tightened to fix the support component 3. Then, the height of the support plate 33 is adjusted according to the size of the perforated plate. After loosening the nut on the surface of the screw 34, the height of the support plate 33 can be adjusted on the outside of the connecting frame 32. Then, the nut on the surface of the screw 34 is tightened to fix it.

[0017] Furthermore, after the plate is clamped into the plate rolling machine 2, the second knob 42 is loosened and the pusher 46 is pushed forward, so that the second sleeve 41 slides on the top of the support frame 1. After the pressure roller 48 contacts one end of the perforated plate, it is pushed forward and pressure is applied, so that one end of the perforated plate is in contact with the backing plate 33 and the other end is in close contact with the pressure roller 48. At this time, the spring 47 is fully compressed and the telescopic rod 45 moves backward in the guide tube 44. Then the second knob 42 is tightened to fix the pressure component 4. Since the spring 47 is fully compressed, the pressure roller 48 no longer has room to move backward. The reaction force of the spring 47 will always press one end of the perforated plate against the surface of the backing plate 33, thereby ensuring that the end of the cylinder rolled by the plate rolling machine 2 is flush and ensuring the rolling effect of the muffler perforated tube.
