Description

Silencer support
Technical Field
The present invention relates to a muffler bracket, and more particularly, to a muffler bracket that can fasten a muffler, which reduces noise of exhaust gas discharged from an engine of an excavator, to the excavator.
Background
In general, an excavator is a construction machine used for excavation work of excavating earth at a construction site, loading work of carrying sand, crushing work of demolishing a building, land preparation work of finishing a ground, and the like, and includes an engine generating driving force, a muffler for reducing noise of exhaust gas discharged from the engine, and a muffler bracket fastening the muffler to the excavator.
However, the conventional muffler bracket has problems in that it cannot stably support the muffler and the manufacturing cost is increased.
Specifically, the muffler is generally formed in a cylindrical shape.
However, when the muffler bracket is formed as a flat plate in line contact with the outer circumference of the muffler, the contact area between the muffler and the muffler bracket is narrow, and thus the muffler is unstably supported.
In contrast, when the muffler bracket is formed as a curved plate in surface contact with the outer circumferential surface of the muffler, although the muffler is stably supported, a curved surface punching process is added to manufacture the curved plate, resulting in an increase in manufacturing cost.
In addition, when the thickness of the curved plate is thick, the accuracy is low, and thus the curved surface punching process needs to be performed a plurality of times, and after the plurality of times of the curved surface punching process, operations for improving the accuracy, such as post-processing, are also performed, thereby further increasing the manufacturing cost.

Here, for convenience of explanation, the fastening member is not illustrated in fig. 1.
Referring to fig. 1 to 4, a muffler bracket according to an embodiment of the present invention may include: a base plate 210 facing the muffler 100; a side plate 220 extending from the base plate 210 toward the muffler 100; a fastening member 240 that fastens the muffler 100 to the base plate 210 and the side plate 220; and a lug 250 protruding from the base plate 210 to the opposite side of the side plate 220 and fastened to the upper rotator.
The base plate 210 may be formed as a flat plate parallel to the axial direction of the cylindrical muffler 100.
The base plate 210 may include a through hole 212 through which the fastening member 240 passes.
The side plate 220 may be bent from the base plate 210 to be formed as a flat plate substantially perpendicular to the axial direction of the muffler 100.
In addition, the side plate 220 may include a curved surface 230 contacting the outer circumferential surface of the muffler 100.
The curved surface 230 may be formed in a circular arc shape extending in the circumferential direction of the muffler 100 in surface contact with the outer circumferential surface of the muffler 100.
Here, the curved surface 230 may be formed to bring the base plate 210 into line contact with the outer circumference of the muffler 100, so that the muffler 100 is supported not only by the side plates 220 but also by the base plate 210. That is, for example, the radius of curvature of the curved surface 230 may be formed to the same degree as the distance between the center of curvature of the curved surface 230 and the base plate 210 (distance measured in the direction perpendicular to the base plate).
On the other hand, a plurality of the side plates 220 may be formed so that the muffler 100 can be supported by the side plates 220 at a plurality of positions.
That is, the side panel 220 may include: a first side plate 222 bent from one end of the base plate 210 and supporting one end of the muffler 100; and a second side plate 224 bent from the other end portion of the base plate 210 and supporting the other end portion of the muffler 100.
In addition, the first side plate 222 may include: a first side plate first portion 222a supporting one side of one end portion of the muffler 100; and a first side plate second portion 222b that supports the other side of the one end portion of the muffler 100 on the opposite side of the muffler 100 from the first side plate first portion 222 a.
In addition, the second side plate 224 may include: a second side plate first portion 224a supporting one side of the other end portion of the muffler 100; and a second side plate second portion 224b supporting the other end portion of the muffler 100 on the opposite side of the second side plate first portion 224a with respect to the muffler 100.
At this time, the curved surface 230 may include: a first curved surface 232 formed at the first side plate first portion 222 a; a second curved surface 234 formed at the first side plate second portion 222 b; a third curved surface 236 formed at the second side plate first portion 224 a; and a fourth curved surface 238 formed at the second side plate second portion 224 b.
The fastening part 240 may include: a wire 242 wrapping the outer peripheral surface of the muffler 100 and having an end inserted into the through hole 212; and a nut 244 screwed to an end of the wire 242, and configured to attach the muffler 100 to the base plate 210 and the side plate 220 via the wire 242.
The lifting lug 250 may be formed of a plate material separate from the base plate 210 and the side plates 220 and then fastened to the base plate 210 by welding or the like.
Here, the base plate 210, the side plate 220, and the lifting lug 250 may be formed by the following manufacturing method.
That is, the manufacturing method of the muffler bracket of the present embodiment may include: a plate provided with a plate providing step; a cutting step of cutting an end of the flat plate to form the curved surface 230 capable of surface-contacting the muffler 100; a bending step of bending an end of the flat plate having the curved surface 230 to form the base plate 210 and the side plate 220; and a step of forming a lug by fastening the lug 250 to the base plate 210.
The cutting step may include: a first cutting step of forming the first curved surface 232 and the second curved surface 234 at one end portion of the flat plate; and a second cutting step of forming the third curved surface 236 and the fourth curved surface 238 at the other end portion of the flat plate.
In addition, the cutting step may further include: a third cutting step of forming a first groove 262 between the first curved surface 232 and the second curved surface 234; and a fourth cutting step of forming a second groove 264 between the third curved surface 236 and the fourth curved surface 238.
Here, the first and second recesses 262 and 264 may not only facilitate the formation of the side plate 220 in the bending step, but also prevent the deformation of the curved surface 230.
Specifically, when the first groove 262 is not provided, a relatively large force is required to bend the entire first side plate 222, and at this time, if the force is not uniformly applied, the first side plate 222 may be twisted and bent, and the curved surface 230 (more precisely, the portion between the first curved surface 232 and the second curved surface 234) of the first side plate 222 may be deformed. In contrast, when the first groove 262 is formed, the first curved surface 232 and the second curved surface 234 are divided by the first groove 262, so that the first side plate first portion 222a and the first side plate second portion 222b can be bent and formed independently of each other. That is, one of the first side plate first portion 222a and the first side plate second portion 222b may be formed by bending first, and then the other of the first side plate first portion 222a and the first side plate second portion 222b may be formed by bending. Accordingly, the first side plate 222 can be formed with a relatively small force, and the curved surface 230 (more precisely, the portion between the first curved surface 232 and the second curved surface 234) of the first side plate 222 can be prevented from being deformed in advance.
Similarly, when the second groove 264 is not provided, a relatively large force is required to bend the second side plate 224, and when the force is not uniformly applied, the second side plate 224 may be twisted and bent, and the curved surface 230 (more precisely, the portion between the third curved surface 236 and the fourth curved surface 238) of the second side plate 224 may be deformed. In contrast, when the second recess 264 is formed, the third curved surface 236 and the fourth curved surface 238 are divided by the second recess 264, so that the second side plate first portion 224a and the second side plate second portion 224b can be bent and formed independently of each other. That is, one of the second side plate first portion 224a and the second side plate second portion 224b may be bent and formed, and then the other of the second side plate first portion 224a and the second side plate second portion 224b may be bent and formed. Thereby, the second side plate 224 can be formed with a relatively small force, and the curved surface 230 (more precisely, the portion between the third curved surface 236 and the fourth curved surface 238) of the second side plate 224 can be prevented from being deformed in advance.
On the other hand, the first cutting step, the second cutting step, the third cutting step, and the fourth cutting step may be performed sequentially or simultaneously.
The bending step may include: a first bending step of bending an end of the flat plate having the first curved surface 232 to form a first portion 222a of the first side plate; a second bending step of bending an end of the flat plate having the second curved surface 234 to form the first side plate second portion 222 b; a third bending step of bending the other end portion of the flat plate having the third curved surface 236 to form the second side plate first portion 224 a; and a fourth bending step of bending the other end portion of the flat plate having the fourth curved surface 238 to form the second side plate second portion 224 b.
Here, the first bending step, the second bending step, the third bending step, and the fourth bending step may be performed sequentially or simultaneously.
The operation and effect of the muffler bracket of the present embodiment will be explained.
That is, in the muffler bracket, the hanger 250 is fastened to the upper rotating body, the base plate 210 and the side plate 220 support the muffler 100, and the fastening member 240 can fasten the muffler 100 to the upper rotating body by bringing the muffler 100 into close contact with the base plate 210 and the side plate 220.
Here, in the muffler bracket of the present embodiment, the base plate 210 is formed as a flat plate in line contact with the muffler 100, and the side plate 220 has the curved surface 230 in surface contact with the muffler 100 and is formed as a flat plate bent from the base plate 210, so that the muffler 100 can be stably supported and the manufacturing cost can be saved.
Specifically, the muffler 100 is supported not only by the base plate 210, which is a flat plate, but also by the curved surfaces 230 of the side plates 220, so that the contact area between the muffler 100 and the muffler bracket is widened, so that the muffler 100 can be stably supported to the muffler bracket. In this case, since the plurality of side plates 220 are formed, the muffler 100 is more stably supported, and the durability of the muffler 100 and the muffler bracket can be improved.
Further, since the side plate 220 having the curved surface 230 is provided, the base plate 210 does not need to be formed as a curved plate in surface contact with the muffler 100. Accordingly, it is not necessary to perform a curved surface punching process and a post-process for manufacturing the base plate 210 into a curved plate, and thus the manufacturing cost can be reduced.
Of course, although the base plate 210 is not formed as a curved plate but the side plate 220 having the curved surface 230 is provided instead, since the curved surface 230 is formed by cutting and the side plate 220 is formed by bending from the base plate 210, the side plate 220 having the curved surface 230 is easily formed, so that the manufacturing cost required to form the side plate 220 having the curved surface 230 may be less than that required to form the base plate 210 as a curved plate.
On the other hand, in the case of the present embodiment, the base plate 210 and the side plate 220 are in direct contact with the muffler 100, but a cushioning member such as rubber may be interposed between the side plate 220 and the muffler 100 and between the base plate 210 and the muffler 100. However, in this case, when engine vibration, equipment vibration, external impact, or the like occurs, the muffler 100 may vibrate with respect to the muffler bracket due to the buffer member, and a connection portion between the muffler 100 and the exhaust pipe may be damaged. In view of this, as shown in the present embodiment, it is preferable that the base plate 210 and the side plate 220 are in direct contact with the muffler 100 to prevent the muffler 100 from vibrating with reference to the muffler bracket.
