Description

Technical Field

[0001] The present application relates to the technical field of road sound barrier manufacturing, and in particular to a sound barrier U-shaped bending device and a sound barrier automated production line. Background Art

[0002] The sound barrier has excellent anti-vibration and sound absorption and insulation properties, which can effectively reduce the vibration and noise propagation in railway lines, stations and other train areas, help provide a more comfortable and quiet railway environment, and improve the environmental comfort of residents along the railway.

[0003] The unit panels of railway metal sound barriers are mainly divided into three types: Type I, Type II and Type III. During the manufacturing process of the sound barriers, separate equipment is used for punching, punching, shearing and bending. After processing on one device is completed, it needs to be manually transported to the next device, resulting in increased semi-finished product turnover and labor cost investment during the manufacturing process of the metal barrier shell, and low processing efficiency.

[0004] On the other hand, the three different types of sound barriers have significant differences in their shell structure types, making it difficult to achieve co-production of the products. This results in limited product business scope at the production site, high investment in manufacturing equipment, low equipment utilization, large manufacturing site area requirements, and low space utilization.

[0005] Secondly, the Type III sound barrier needs to be processed into a U-shaped cross-section. The existing bending equipment on the market requires at least two operations through manual and equipment collaboration to achieve the requirements of its U-shaped structure processing state. It is difficult to achieve the process efficiency of one-time forming. The existing Type III sound barrier processing equipment on the market needs to fold both sides of the workpiece separately to form a U shape, which results in low processing efficiency.

[0046] See also Figure 1 The utility model embodiment provides a sound barrier U-shaped bending device 5, which is used to bend the workpiece to be processed to form a sound barrier U-shaped bending device 5. Fig. 9 Type III sound barrier 3 shown.

[0047] Since the workpiece needs to be processed to form a Type III sound barrier 3, for the convenience of illustration, the workpiece includes: a first part 31, a second part 32 and a third part 33. The first part 31, the second part 32 and the third part 33 are arranged at intervals along the second direction Y. The first part 31, the second part 32 and the third part 33 of the workpiece are represented as the areas that are about to be processed into the first part 31, the second part 32 and the third part 33 of the Type III sound barrier 3.

[0048] In this embodiment, the sound barrier U-shaped bending device 5 includes a supporting mechanism, a pressing mechanism 56 and a first driving mechanism 53. The supporting mechanism includes a supporting seat 52, a first supporting plate 54 and a second supporting plate 55. The supporting seat 52 is used to support the second part 32, the first supporting plate 54 is used to support the first part 31, and the second supporting plate 55 is used to support the third part 33. The first driving mechanism 53 is configured to drive the first supporting plate 54 to rotate relative to the supporting seat 52 to bend the first part 31 and the second part 32 to a first preset angle, and / or the first driving mechanism 53 is configured to drive the second supporting plate 55 to rotate relative to the supporting seat 52 to bend the third part 33 and the second part 32 to a second preset angle.

[0049] In some embodiments, the first driving mechanism 53 only drives the first supporting plate 54 to rotate relative to the supporting base 52 so that the first portion 31 and the second portion 32 are bent to a first preset angle.

[0050] In some other examples, the first driving mechanism 53 only drives the second supporting plate 55 to rotate relative to the supporting base 52, so that the third portion 33 and the second portion 32 are bent to a second preset angle.

[0051] In some other examples, the first driving mechanism 53 simultaneously drives the first support plate 54 and the second support plate 55 to rotate relative to the support base 52, so that the first part 31 and the second part 32 are bent to a first preset angle, and the third part 33 and the second part 32 are bent to a second preset angle.

[0052] Based on the above structure, in the initial state, the workpiece to be processed is a flat plate, and the support surfaces on the support seat 52, the first support plate 54 and the second support plate 55 are on the same plane. After the pressing mechanism 56 presses the second part 32 on the support seat 52, it drives the first support plate 54 and the second support plate 55 according to actual needs. For example, when it is necessary to bend the first part 31 and the third part 33 at the same time, the first driving mechanism 53 simultaneously drives the first support plate 54 and the second support plate 55 to rotate relative to the support seat 52, so that the first support plate 54 and the support seat 52 are bent at a first preset angle, and the second support plate 55 and the fixed seat 21 are bent at a second preset angle. At this time, since the second part 32 of the workpiece to be processed is pressed on the support seat 52, the first part 31 and the third part 33 are driven to be bent relative to the second part 32 during the rotation of the first support plate 54 and the second support plate 55, so that the first part 31, the second part 32 and the third part 33 are bent into a U-shaped shell, so that the present application can achieve the bending effect of the workpiece to be processed and improve the bending efficiency of the workpiece to be processed.

[0053] In one embodiment, see Figure 4 The first driving mechanism 53 includes: a first cylinder 531 and a second cylinder 532. The cylinder barrel of the first cylinder 531 is hinged to the frame 1, the telescopic shaft of the first cylinder 531 is hinged to the first support plate 54, the cylinder barrel of the second cylinder 532 is hinged to the frame 1, and the telescopic shaft of the second cylinder 532 is hinged to the second support plate 55, so that the first cylinder 531 and the second cylinder 532 can respectively drive the first support plate 54 and the second support plate 55 to rotate relative to the support seat 52.

[0054] It is understandable that the present application can also use a hydraulic cylinder instead of a pneumatic cylinder to drive the first support plate 54 and the second support plate 55 to rotate relative to the support seat 52 .

[0055] In this embodiment, see Figure 4 The number of the first cylinder 531 and the second cylinder 532 is multiple, so as to improve the supporting force of the first support plate 54 and the second support plate 55, so that the first support plate 54 has a better bending effect on the first part 31, and the second support plate 55 has a better bending effect on the third part 33.

[0056] In one embodiment, see Figure 7 The pressing mechanism 56 includes: a third cylinder 561 and a pressing plate 562. The third cylinder 561 is arranged on the frame 1, and the output shaft of the third cylinder 561 is connected to the pressing plate 562. The pressing plate 562 is driven by the third cylinder 561 to approach or move away from the support seat 52, so that the workpiece to be processed is pressed on the support seat 52 through the pressing plate 562.

[0057] See also Figure 1The embodiment of the utility model also provides an automated production line for sound barriers, which has an intersecting first direction X and a second direction Y, and is used to process the workpiece to be processed. In the description of this application, "at least two" means two or more.

[0058] See also Figure 1 , Figure 8 as well as Fig.11 The automatic production line of the sound barrier includes: a frame 1, a conveying device 2, a punching device 4, a flipping device 9 and the sound barrier U-shaped bending device 5 as described above. Among them, the sound barrier U-shaped bending device 5 also includes a conveying mechanism 51. The conveying device 2 is arranged on the frame 1, and the conveying device 2 is used to convey the workpiece to be processed to the first position along the first direction. In this embodiment, the length direction of the workpiece to be processed is the first direction X, and the width direction of the workpiece to be processed is the second direction Y.

[0059] See also Figure 1 The punching device 4 is disposed on the frame 1, and is configured to punch holes in the workpiece to be processed when the conveying device 2 conveys the workpiece to be processed, so as to form holes required for processing on the workpiece to be processed.

[0060] See also Figure 11-13 The turning device 9 is disposed on the frame 1, and the turning device 9 is configured to move the workpiece to be processed from the first position to the second position, so that the punched workpiece to be processed can be moved from the first position to the second position.

[0061] See also Figure 2-Figure 5 The conveying mechanism 51 is disposed on the frame 1, and the conveying mechanism 51 is configured to move the workpiece to be processed from the second position to the support seat 52, the first support plate 54 and the second support plate 55 along the first direction. The first support plate 54 and the second support plate 55 are respectively hinged on the two opposite sides of the support seat 52 along the second direction. The first driving mechanism 53 is configured to drive the first support plate 54 to rotate relative to the support seat 52 to bend the first part 31 and the second part 32 to the first preset angle, and / or the first driving mechanism 53 is configured to drive the second support plate 55 to rotate relative to the support seat 52 to bend the third part 33 and the second part 32 to the second preset angle.

[0062] Based on the above structure, during the operation of the automatic production line of the sound barrier of the present application, the workpiece to be processed is first transported to the first position along the first direction X by the conveying device 2, and the punching device 4 performs a punching process on the workpiece to be processed during the conveying process of the conveying device 2. After the workpiece to be processed is punched and transported to the first position, the flipping device 9 flips the workpiece to be processed at the first position to the second position, and then the conveying mechanism 51 transports the workpiece to be processed from the second position along the first direction X and transports it to the support seat 52, the first support plate 54 and the second support plate 55. At this time, the first part 31 is supported on the first support plate 54, the second part 32 is supported on the support seat 52, and the third part 33 is supported on the second support plate 55. Then, the second part 32 is pressed against the support seat 52 by the pressing mechanism 56. At this time, the support surfaces on the support seat 52, the first support plate 54 and the second support plate 55 are on the same plane. After the pressing mechanism 56 presses the second part 32 against the support seat 52, it drives the first support plate 54 and the second support plate 55 according to actual needs. For example, when it is necessary to bend the first part 31 and the third part 33 at the same time, the first driving mechanism 53 simultaneously drives the first support plate 54 and the second support plate 55 to rotate relative to the support seat 52, so that the first support plate 54 and the support seat 52 are bent at a first preset angle, and the second support plate 55 and the fixed seat 21 are bent at a second preset angle. At this time, since the second part 32 of the workpiece to be processed is pressed on the support seat 52, the first part 31 and the third part 33 are driven to be bent relative to the second part 32 during the rotation of the first support plate 54 and the second support plate 55, so that the first part 31, the second part 32 and the third part 33 are bent into a U-shaped shell, so that the present application can realize the integration of punching and bending of the workpiece to be processed, thereby improving the processing effect of the workpiece to be processed. Secondly, in this embodiment, the workpiece to be processed has a first plate surface and a second plate surface. During the transportation process of the conveying device 2, the first plate surface is facing downward and the second plate surface is facing upward. After the punching device 4 punches, burrs will be formed at the hole positions of the workpiece to be processed, and the burrs protrude from the first plate surface of the workpiece to be processed. In this application, the first plate surface of the workpiece to be processed faces upward and the second plate surface faces downward after entering the second position through the setting of the flipping device 9, so that after the subsequent bending by the sound barrier U-shaped bending device 5, the first plate surface is the inner side surface of the U-shaped shell to hide the burrs and prevent the burrs from being exposed on the outside of the U-shaped shell. Secondly, the setting of the flipping device 9 can also set the conveying device 2 and the punching device 4 in one position, and then set the sound barrier U-shaped bending device 5 in another position, and then transfer the workpiece to be processed from the conveying device 2 to the sound barrier U-shaped bending device 5 through the flipping device 9, so as to avoid the situation where all components can only be arranged along the same straight line, resulting in the need for a larger factory building, so that the overall layout of the sound barrier automation production line is more reasonable. Furthermore, by using a conveying device 2 to connect various devices, the processing capacity of the Type III sound barrier 3 can be increased by 3-5 times.

[0063] In one embodiment, see Figure 11-13 , the flipping device 9 includes: a first slide rail 91, a sliding seat 92, a clamping mechanism 93, and a second driving mechanism 94. The sliding seat 92 is slidably arranged on the first slide rail 91. The clamping mechanism 93 is rotatably connected to the sliding seat 92, and the second driving mechanism 94 is transmission-connected to the clamping mechanism 93. The clamping mechanism 93 is configured to move between the first position and the second position under the drive of the second driving mechanism 94. Based on this, the present application can connect the conveying device 2 and the sound barrier U-shaped bending device 5 through the first slide rail 91. When it is necessary to move the workpiece to be processed from the first position to the sound barrier U-shaped bending device 5, the sliding seat 92 is first slid on the first slide rail 91 to make the clamping mechanism 93 slide to the first position and clamp the workpiece to be processed on the conveying device 2, and then the sliding seat 92 slides toward the flipping device 9 and drives the clamping mechanism 93 to rotate through the second driving mechanism 94, so that the workpiece to be processed clamped by the clamping mechanism 93 can fall into the second position.

[0064] In this embodiment, the length of the first slide rail 91 can be set according to the actual installation position. The setting of the first slide rail 91 can make the installation position of the sound barrier automation production line of the present application more flexible.

[0065] In one embodiment, see Fig.12 and Fig.13 The clamping mechanism 93 includes: a plurality of clamping groups. The plurality of clamping groups are arranged on the sliding seat 92 at intervals along the first direction X. The clamping group includes: a seat body 931, a first clamping rod 932 and a second clamping rod 933. The seat body 931 is rotatably connected to the sliding seat 92, and the first clamping rod 932 and the second clamping rod 933 are respectively connected to the seat body 931. There is a storage space for accommodating the workpiece to be processed between the first clamping rod 932 and the second clamping rod 933. Specifically, the first clamping rod 932 and the second clamping rod 933 extend along the second direction Y, so that the workpiece to be processed can enter between the first clamping rod 932 and the second clamping rod 933 of the plurality of clamping groups along the first direction X after being conveyed by the conveying device 2, so as to achieve the clamping of the workpiece to be processed.

[0066] When the workpiece to be processed enters the clamping group from the conveying device 2, the workpiece to be processed is separated from the power of the conveying device 2, so that the workpiece to be processed can only enter part of the clamping group. In order to solve this problem, the turning device 9 also includes: a first mounting seat 95 and a plurality of first conveying rollers 96. The first conveying rollers 96 are rotatably connected to the first mounting seat 95, and the plurality of first conveying rollers 96 are arranged at intervals along the first direction X. A first gap is provided between two adjacent first conveying rollers 96 for the first clamping rod 932 to pass through.

[0067] In one embodiment, see Figure 6 and Fig.11 The flip device 9 further includes a placement seat 97. The placement seat 97 is provided with a plurality of avoidance grooves 971 for the second clamping rod 933 to enter, and the plurality of avoidance grooves 971 are arranged at intervals along the first direction X. Specifically, the first mounting seat 95 and the placement seat 97 are arranged at intervals along the second direction Y, and the first slide rail 91 extends along the second direction, so that the sliding seat 92 can slide on the first slide rail 91 along the second direction Y to move back and forth between the first mounting seat 95 and the placement seat 97.

[0068] Based on this, the present application adopts the accommodation space formed between the first clamping rod 932 and the second clamping rod 933 to accommodate the workpiece to be processed. Before the conveying device 2 conveys the workpiece to be processed to the multiple first conveying rollers 96, the first clamping rod 932 enters the first gap so that the upper surface of the first clamping rod 932 and the first conveying roller 96 forms an end surface for placing the workpiece to be processed. At this time, the second clamping rod 933 is located above the first clamping rod 932. When the workpiece to be processed completely enters the multiple first conveying rollers 96, the first conveying rollers 96 and the first clamping rod 932 are located below the workpiece to be processed, and the second clamping rod 933 is located above the workpiece to be processed. Then, the second driving mechanism 94 drives the seat body 931 relative to the sliding seat 92 rotates so that the first clamping rod 932 leaves the first gap so that the first clamping rod 932 and the second clamping rod 933 bring the workpiece to be processed away from the first conveying roller 96, and then the sliding seat 92 slides on the first slide rail 91 toward the placement seat 97, and finally the second driving mechanism 94 drives the seat body 931 to rotate relative to the sliding seat 92, so that the second clamping rod 933 enters the avoidance groove 971, so that the workpiece to be processed is supported on the placement seat 97, at this time, the workpiece to be processed is separated from the support of the second clamping rod 933, and at this time, the sliding seat 92 slides on the first slide rail 91 toward the first conveying roller 96 to make the second clamping rod 933 exit the avoidance groove 971, and repeat the above steps to realize the conveying of the workpiece to be processed.

Secondly, since the workpiece to be processed in the present application is iron sheet, it is easy to slip during the transportation process. Therefore, the present application sets a roller to press the workpiece to be processed onto the second conveying roller 22 or the fixed seat 21, so that the workpiece to be processed is always in contact with the second conveying roller 22, thereby increasing the friction between the workpiece to be processed and the second conveying roller 22 to prevent the workpiece to be processed from slipping during the transportation process.

[0071] Exemplarily, a plurality of brackets and rollers can be provided, and the plurality of brackets and rollers are spaced apart along the first direction, so that the workpiece can always be in contact with the first conveying roller 96 during the process of being conveyed on the first conveying roller 96 .
