Description

Technical Field

[0001] This utility model belongs to the field of bar stamping technology, specifically relating to a batch stamping device for metal bars used in bridge construction. Background Technology

[0002] Metal rods are commonly used in bridge construction to connect components. The ends of these metal rods often need to be stamped and drilled to facilitate the subsequent connection between the metal rods and various bridge components.

[0003] A related technology (publication number CN215745738U) discloses a bar processing stamping forming equipment. The equipment involves placing the bar to be processed into a feeding box. The bar first falls onto an inclined placement plate. Due to the inclination angle of the placement plate, the bar rolls towards a feeding plate at one end. An electric rotating shaft is installed at one end of the feeding plate, which drives the feeding plate to rotate, changing its angle and increasing the gap between the feeding plate and the inclined placement plate. The bar rolls to the gap due to the angle change and is dropped. When the bar reaches the exit slide, it slides directly out of the feeding port and onto the slide rail assembly for further inertial movement. Compared to general bar processing stamping forming mechanisms, this invention improves the feeding effect during the bar processing stamping forming process, making the feeding process smoother and preventing the bar from clogging the feeding outlet.

[0004] However, in the existing metal bar stamping process, the bars in the hopper are piled up in batches, which often requires manual feeding one by one. It is difficult to automatically and continuously feed the metal bars, which brings inconvenience to the subsequent metal bar stamping. Utility Model Content

[0005] To address the problems in existing metal bar stamping processes, where large batches of bars accumulate in the hopper, requiring manual loading one by one, and hindering continuous and automated feeding, thus causing inconvenience for subsequent stamping, this invention provides a batch stamping device for metal bars used in bridge construction. This device enables automatic, one-by-one feeding of metal bars, avoiding the disorderly accumulation of bulk materials within the conveyor hopper and ensuring sequential feeding. Compared to traditional manual loading, this method is more continuous, saves time on bulk metal bar loading, and facilitates subsequent continuous stamping processing. The specific technical solution is as follows:

[0006] A batch stamping device for metal bars used in bridge construction includes a workbench with a conveying bin at the top and a storage bin connected to the rear of the conveying bin. The storage bin is inclined upwards from front to back. Several metal bars are placed inside the conveying bin and the storage bin, forming a channel for feeding the metal bars. A motor is installed on the side wall of the conveying bin, and a rotating shaft is connected to the output end of the motor. The rotating shaft is rotatably connected to the inner side wall of the conveying bin. Several push rods are arranged circumferentially on the outer wall of the rotating shaft, and the spacing between two adjacent push rods arranged circumferentially is equal. The several push rods arranged circumferentially form a push assembly. A clearance groove corresponding to the position of the push rod is opened at the bottom of the conveying bin.

[0007] In the above technical solution, the push component is provided in multiple groups, and each group of push components is equidistant from each other along the horizontal direction of the rotating axis.

[0008] In the above technical solution, the push rod is bent forward.

[0009] In the above technical solution, a fixing rod is provided on the inner wall of the storage bin, and a limit plate is fixedly installed on the outer wall of the fixing rod.

[0010] In the above technical solution, the limiting plate is set to an arc shape on the side opposite to the outer wall of the metal rod.

[0011] In the above technical solution, a through groove is provided through the side wall of the storage bin, a first cylinder is installed on the upper surface of the storage bin, a lifting block is connected to the output end of the first cylinder, and the lifting block is fixedly connected to the outer wall of the fixed rod.

[0012] In the above technical solution, a receiving trough is provided on the front side of the conveying bin, and a guiding trough is connected to the left side of the receiving trough. The receiving trough and the guiding trough are respectively installed on the upper surface of the workbench. A second cylinder is installed on the upper surface of the workbench. The output end of the second cylinder extends into the inner cavity of the receiving trough. A stamping assembly is provided at the output end on the left side of the guiding trough.

[0013] In the above technical solution, the stamping assembly includes a housing mounted on the upper surface of the workbench, and the housing is configured as a semi-enclosed structure. The inner cavity of the housing corresponds to the output end on the left side of the guide groove. A through hole is provided at the bottom of the housing. A third cylinder is mounted on the upper surface of the housing. A punch is mounted at the output end of the third cylinder, and the punch is vertically aligned with the through hole.

[0014] In the above technical solution, the inner cavities of both the receiving trough and the guiding trough are V-shaped.

[0015] In the above technical solution, a support column is fixedly installed on the top of the workbench, the support column is fixedly connected to the side wall of the storage bin, and four support feet are vertically arranged on the lower surface of the workbench.

[0016] The present invention provides a batch stamping device for metal bars used in bridge construction, which, compared with the prior art, has the following advantages:

[0017] I. In the existing metal bar stamping process, the metal bars in the hopper often pile up in batches, requiring manual feeding one by one. It is difficult to automatically and continuously feed the metal bars, which brings inconvenience to the subsequent metal bar stamping. This utility model uses the rotation of motor, shaft and push rod to make the metal bars in the conveying hopper and storage hopper be conveyed one by one to the receiving trough. It avoids the problem of batch materials piling up disorderly in the conveying hopper and making it difficult to unload in sequence. The metal bars can be automatically fed one by one. Compared with the traditional manual feeding method, it is more continuous and more conducive to the continuous stamping of metal bars, saving the feeding time of batch metal bars.

[0018] II. By setting a fixed rod and a limiting plate, this utility model can limit the upper layer of metal rods in the inner cavity of the storage bin, ensuring that the metal rods in the inner cavity of the storage bin enter the inner cavity of the conveying bin in a single layer, and further ensuring that the single layer of metal rods are conveyed one by one to the inner cavity of the receiving trough to achieve automated feeding.

[0019] Third, this utility model, through the setting of through groove, first cylinder and lifting block, can adjust the height of fixed rod and limit plate, so as to flexibly block metal rods of different diameters and meet the needs of single-layer conveying of metal rods of different diameters.

[0020] IV. This utility model, through the setting of the receiving groove and the second cylinder, can push a single metal rod into the inner cavity of the guide groove, thereby realizing the horizontal displacement of the metal rod.

[0021] V. This utility model, by means of a third cylinder, through hole, and punch, is able to punch and drill holes at the end of a metal rod.

[0022] In summary, this invention enables automatic feeding of metal bars one by one, avoiding the problem of disorderly accumulation of batch materials in the conveying chamber, which makes sequential feeding difficult. Compared with the traditional manual feeding method, it is more continuous, saves feeding time for batch metal bars, and is more conducive to the continuous stamping processing of subsequent metal bars. In addition, it can ensure that the metal bars in the storage chamber enter the conveying chamber in a single layer, further ensuring that the single-layer metal bars are automatically fed to the receiving trough one by one. Moreover, the height of the fixing rod and the limiting plate can be adjusted, so as to flexibly block metal bars of different diameters. Attached Figure Description

[0029] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0030] See Figures 1 to 5As shown, a batch stamping device for metal bars used in bridge construction includes a workbench 1, a conveying chamber 2 at the top of the workbench 1, and a storage chamber 3 connected to the rear of the conveying chamber 2. The storage chamber 3 is inclined upwards from front to back. Several metal bars 14 are placed inside the conveying chamber 2 and the storage chamber 3, forming a channel for feeding the metal bars 14. The metal bars 14 can move forward along the inner cavity of the channel formed by the conveying chamber 2 and the storage chamber 3, realizing the feeding of the metal bars 14 one by one. A motor 4 is installed on the side wall of the conveying chamber 2, and a rotating shaft 5 is connected to the output end of the motor 4. The rotating shaft 5 is rotatably connected to the inner side wall of the conveying chamber 2 through a bearing. 4 can drive the rotating shaft 5 to rotate circumferentially. Several push rods 6 are arranged circumferentially on the outer wall of the rotating shaft 5. In this embodiment, there are four push rods 6, and the spacing between two adjacent push rods 6 arranged circumferentially is equal, that is, each two adjacent push rods 6 are spaced 90 degrees apart. Several push rods 6 arranged circumferentially form a push assembly. The rotation of the rotating shaft 5 causes the push rods 6 to rotate synchronously, so as to flip and push the metal rod 14 in the inner cavity of the conveying chamber 2 forward. The bottom end of the conveying chamber 2 is provided with a relief groove 7 corresponding to the position of the push rod 6. The relief groove 7 provides sufficient rotation space for the circumferential rotation of the push rod 6 and will not interfere with the rotation of the push rod 6.

[0031] For details, please refer to [link / reference]. Figure 1 and Figure 3 As shown, multiple sets of push components are provided. In this embodiment, four sets of push components are provided, and each set of push components is equidistant from each other along the horizontal direction of the rotation axis 5. (See reference...) Figure 3 As shown, four sets of pushing components are equidistantly arranged along the outer wall of the rotating shaft 5, which can support the outer wall of the metal rod 14 and cause the metal rod 14 to move forward under the rotation of the rotating shaft 5 and the pushing rod 6 to achieve feeding. The pushing rod 6 is bent forward, which ensures that the counterclockwise rotating shaft 5 and the pushing rod 6 can support the metal rod 14 and increase the contact area between the pushing rod 6 and the metal rod 14. Compared with the vertically arranged pushing rod 6, it can better ensure the stability of the metal rod 14 when it rotates with the pushing rod 6.

[0032] See also Figure 1 and Figure 2 As shown, a fixing rod 8 is provided on the inner wall of the storage bin 3, and a limiting plate 9 is fixedly installed on the outer wall of the fixing rod 8. The limiting plate 9 can block the upper metal rod 14, ensuring that the single-layer metal rod 14 can pass smoothly under the limiting plate 9. The side opposite to the outer wall of the limiting plate 9 and the metal rod 14 is set as arc-shaped to ensure that the metal rod 14 blocked by the limiting plate 9 can fit more tightly with the arc-shaped outer wall of the limiting plate 9, thus ensuring the stability of the limited metal rod 14.

[0033] In addition, see Figure 1As shown, a through groove 10 is provided through the side wall of the storage bin 3. A first cylinder 11 is installed on the upper surface of the storage bin 3. A lifting block 12 is connected to the output end of the first cylinder 11. The lifting block 12 is fixedly connected to the outer wall of the fixed rod 8. The lifting block 12 is driven to move vertically in the cavity of the through groove 10 by the activated first cylinder 11, thereby realizing the adjustment of the height of the fixed rod 8 and the limiting plate 9, so that the position of the limiting plate 9 can flexibly meet the blocking requirements of metal rods 14 of different diameters.

[0034] See Figure 1 , Figure 4 and Figure 5 As shown, a receiving trough 15 is provided on the front side of the conveying bin 2, and a guide trough 16 is connected to the left side of the receiving trough 15. The receiving trough 15 and the guide trough 16 are respectively installed on the upper surface of the workbench 1. A second cylinder 17 is installed on the upper surface of the workbench 1. The output end of the second cylinder 17 extends into the inner cavity of the receiving trough 15. By opening the second cylinder 17, the metal rod 14 in the inner cavity of the receiving trough 15 is forced to enter the inner cavity of the guide trough 16 to the left. A stamping assembly is provided at the output end on the left side of the guide trough 16. The stamping assembly performs stamping and drilling processing on the metal rod 14. The inner cavities of the receiving trough 15 and the guide trough 16 are both set as V-shaped, so as to ensure that after the metal rod 14 enters the inner cavity of the receiving trough 15 and the guide trough 16, it can be automatically centered under the limit of the V-shaped inner cavity, without the need for additional centering operation on the metal rod 14, ensuring that the metal rod 14 can be automatically centered when it is stamped later.

[0035] For details, please refer to [link / reference]. Figure 1 and Figure 4 As shown, the stamping assembly includes a housing 18 mounted on the upper surface of the worktable 1, and the housing 18 is configured as a semi-enclosed structure. The inner cavity of the housing 18 corresponds to the output end of the left side of the guide groove 16. A through hole 19 is provided at the bottom end of the housing 18. A third cylinder 20 is mounted on the upper surface of the housing 18. A punch 21 is mounted on the output end of the third cylinder 20, and the punch 21 is vertically aligned with the through hole 19. The punch 21 is driven to move downward by the output end of the opened third cylinder 20 to stamp the end of the metal rod 14.

[0036] To ensure the stability of the storage bin 3 installed on the top of the workbench 1, a support column 13 is fixedly installed on the top of the workbench 1. The support column 13 is fixedly connected to the side wall of the storage bin 3. With the help of the support column 13, a stable support relationship can be formed between the storage bin 3 and the workbench 1. Four support feet 22 are vertically arranged on the lower surface of the workbench 1. With the help of the support feet 22, a certain distance can be left between the workbench 1 and the ground to meet the height requirements of the assembly line operation.

[0037] The working principle of the batch stamping device for bridge construction metal bars in this embodiment is as follows:

[0038] The metal rod 14 to be processed is placed into the inner cavity of the storage bin 3. Under the blocking action of the limiting plate 9, and with the storage bin 3 tilted forward, the single layer of metal rods 14 at the bottom of the inner cavity of the storage bin 3 rolls down one by one. The metal rods 14 are temporarily stopped in the inner cavity of the conveying bin 2 under the blocking action of the push rod 6. Under the action of the motor 4, the rotating shaft 5 and the push rod 6 are rotated forward. As the push rod 6 rotates forward, the metal rods 14 are tumbled forward and fall into the inner cavity of the receiving trough 15. Since the push rods 6 are set at 90 degrees with the outer wall of the rotating shaft 5, when the push rod 6 rotates counterclockwise to convey a single metal rod 14 into the inner cavity of the receiving trough 15, the metal rods 14 on the rear side are temporarily stopped in the inner cavity of the conveying bin 2 under the blocking action of the adjacent push rod 6. Thus, by rotating the push rod 6 90 degrees, the conveying of a single metal rod 14 is realized.

[0039] The second cylinder 17 is activated to cause the metal rod 14 in the inner cavity of the receiving groove 15 to enter the inner cavity of the guide groove 16 to the left. At this time, the end of the metal rod 14 is located in the inner cavity of the housing 18. The output end of the third cylinder 20 is activated to drive the punch 21 to move downward and perform stamping processing on the end of the metal rod 14.

[0040] If the diameter of the metal rod 14 changes, the lifting block 12 is driven to move vertically in the cavity of the through groove 10 by the first cylinder 11, thereby adjusting the height of the fixed rod 8 and the limiting plate 9 so that the position of the limiting plate 9 can flexibly meet the blocking requirements of metal rods 14 of different diameters.

[0041] This invention enables automatic feeding of metal rods 14 one by one, avoiding the problem of disorderly accumulation of batch materials in the inner cavity of the conveying chamber 2, which makes it difficult to achieve sequential feeding. Compared with the traditional manual feeding method, it is more continuous, saves the feeding time of batch metal rods 14, and is more conducive to the continuous stamping processing of metal rods 14. In addition, it can ensure that the metal rods 14 in the inner cavity of the storage chamber 3 enter the inner cavity of the conveying chamber 2 in a single layer, further ensuring that the single layer of metal rods 14 is automatically fed to the inner cavity of the receiving trough 15 one by one. Moreover, the height of the fixing rod 8 and the limiting plate 9 can be adjusted, so as to flexibly block metal rods 14 of different diameters.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
