Description

TECHNICAL FIELD

[0001] The embodiment of the utility model relates to the technical field of bicycle pipe processing, more particularly, the utility model relates to a pipe processing equipment for bicycles. BACKGROUND

[0002] In the bicycle manufacturing industry, pipe material as the main component of the bicycle frame bears the weight of the entire vehicle and ensures the stability and safety during riding, so its quality and processing efficiency are directly related to the overall performance and production cost of the bicycle. Traditional bicycle pipe processing methods such as stamping, punching and drilling, although to some extent can meet the basic production needs, ensure the basic functions and appearance of the bicycle, but in the actual operation process, these traditional processing methods have many shortcomings, which seriously affect the processing efficiency and quality of the pipe, and further restrict the further development of the bicycle manufacturing industry.

[0003] Specifically, in the prior art, when stamping, punching, drilling and other processing operations are performed on the bicycle pipe, multiple independent equipment and machine tools are usually required to complete the operation. This dispersed processing mode means that during the entire processing process, the operator needs to clamp and position the pipe multiple times and transport it. Each clamping and transporting requires a lot of time and effort, and is prone to cause positioning errors and shape errors of the pipe, thereby affecting the subsequent processing precision and overall quality. In addition, multiple clamping and transporting also increases the risk of damage to the pipe during processing, directly affecting the quality of the final product. Therefore, this dispersed processing method in the prior art not only has low efficiency, but also cannot guarantee the processing quality, and has been unable to meet the needs of the bicycle manufacturing industry for efficient and high-quality pipe processing. UTILITY MODEL CONTENT

[0004] In order to solve one or more technical problems mentioned above, the utility model provides a pipe processing equipment for bicycles, which integrates stamping, punching, drilling and other processes in a single device, avoiding the need for multiple clamping and transporting in traditional processing methods. This not only greatly reduces the labor intensity and processing time of the operator, but also makes the entire processing process more smooth and efficient, effectively improving the overall productivity of the production line.

[0030] Specifically, by adjusting the length of the first adjusting rod passing through the first lower mold, the fourth cylinder pushes the second pushing block to move to abut against the first identified first part to be processed before the first upper mold and the first lower mold come close together, thereby adjusting the position of the first identified first part to be processed.

[0033] The second upper die includes a first sub-die and a second sub-die.

The second sub-die is provided with a second receiving groove for accommodating the second part to be processed after stamping.

[0034] A buffer assembly is used to support the tube and maintain a certain distance between the first part to be processed after stamping and the first receiving groove.

[0035] The fifth cylinder is mounted on the frame;

[0036] The sixth cylinder, which is mounted on the frame; and

[0038] Furthermore, the buffer component includes:

[0039] The first support block is used to support the second part to be processed after being stamped;

[0040] The second support block is disposed between the second lower die and the first support block, and is used to support the tube between the first part to be processed after stamping and the second part to be processed after stamping.

[0058] Furthermore, the moving mechanism is a plurality of clamp-type or suction-type material handling robots mounted on the frame.

[0059] The bicycle tubing processing equipment provided by this utility model can accurately identify the position of the weld lines inside the tubing through an identification and positioning mechanism. This allows for adjustment of the weld line position within the tubing using the identification and positioning mechanism, ensuring that the weld lines are positioned correctly before the tubing is transported to the trimming and stamping mechanism. This reduces the possibility of cracking or breakage during the trimming and stamping process. Since the first part of the tubing to be processed requires stamping and punching, and the second part requires stamping, the trimming and stamping mechanism and the punching mechanism perform stamping and punching operations sequentially. This avoids the problem of hole deformation caused by punching before stamping, thus reducing the risk of hole deformation and improving hole accuracy. The drilling mechanism can drill holes in the second part of the tubing separately after the first part has been processed, making the processing flow more efficient. The moving mechanism is responsible for precisely moving the tubing to each processing position, ensuring the continuity and automation of the processing. Furthermore, by integrating multiple processes such as stamping, punching, and drilling into a single machine, the need for multiple clamping and transfer operations required in traditional processing methods is eliminated. This not only significantly reduces the labor intensity and processing time for operators but also makes the entire processing flow smoother and more efficient, effectively increasing the overall capacity of the production line. It enables efficient and precise processing of bicycle tubing, reduces errors and scrap rates during processing, and improves production efficiency and product quality. Attached Figure Description

[0079] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0080] Figure 1 This embodiment shows a structural schematic diagram of a tube processing device for bicycles. Figure 2 A schematic diagram of the structure of the pipe provided in this embodiment, which has undergone stamping, punching, and drilling, is shown. Figure 1 and Figure 2As shown, this utility model embodiment provides a bicycle tubing processing device, which includes a frame 1, an identification and positioning mechanism 2, a trimming and stamping mechanism 3, a punching mechanism 4, a drilling mechanism 5, and a moving mechanism 6. The identification and positioning mechanism 2 is mounted on the frame 1 and can identify the welding wire positions inside the tubing 100. The trimming and stamping mechanism 3 is mounted on the frame 1 and is used to punch the first processing section 101 and the second processing section 102 of the tubing 100 after being identified by the identification and positioning mechanism 2. The punching mechanism 4 is mounted on the frame 1 and is used to punch holes in the first processing section 101 after being punched by the trimming and stamping mechanism 3. The drilling mechanism 5 is mounted on the frame 1 and is used to drill holes in the second processing section 102 of the tubing 100 after being punched by the punching mechanism 4. The moving mechanism 6 is mounted on the frame 1 and is used to move the tubing 100 to the identification and positioning mechanism 2, the trimming and stamping mechanism 3, the punching mechanism 4, or the drilling mechanism 5.

[0081] The bicycle tubing processing equipment provided by this utility model can accurately identify the position of the weld line inside the tubing 100 through the identification and positioning mechanism 2. The position of the weld line inside the tubing 100 can be adjusted on the identification and positioning mechanism 2, ensuring that the weld line inside the tubing 100 is in the designated position before being transported to the edge-cutting and stamping mechanism 3. This reduces the possibility of cracking or breaking of the tubing 100 during stamping by the edge-cutting and stamping mechanism 3. Since the first processing part 101 of the tubing 100 needs to undergo stamping and punching operations, and the second processing part 102 of the tubing 100 needs to undergo stamping operations, the edge-cutting and stamping mechanism 3 and the punching mechanism 4 perform stamping and punching operations on the tubing 100 sequentially. This avoids the problem of hole deformation caused by the processing method of punching before stamping, thereby reducing the risk of hole deformation and improving the accuracy of the hole position. The drilling mechanism 5 allows for separate drilling of the second processing section 102 after the first processing section 101 of the bicycle tube 100 has been processed by the bicycle tube processing equipment, making the processing flow more efficient. The moving mechanism 6 is responsible for precisely moving the tube 100 to each processing position, ensuring the continuity and automation of the processing process. Furthermore, by integrating multiple processes such as stamping, punching, and drilling into a single device, the need for multiple clamping and transfer operations in traditional processing methods is avoided. This not only significantly reduces the labor intensity and processing time of operators but also makes the entire processing flow smoother and more efficient, effectively improving the overall capacity of the production line, achieving efficient and precise processing of the bicycle tube 100, reducing errors and scrap rates during processing, and improving production efficiency and product quality.

[0082] Figure 3 A schematic diagram of the identification and positioning mechanism 2 provided in this embodiment is shown. Figure 3 and combined Figure 1As shown, the identification and positioning mechanism 2 includes two first positioning blocks 21 respectively located on the frame 1 at both ends of the pipe 100 along its length, and a limiting component 22 for pushing the two ends of the pipe 100. Each first positioning block 21 has a first positioning groove 211 for abutting against the pipe wall of the pipe 100. The limiting component 22 includes a first cylinder 221 located on the frame 1 and a first pushing block 222 connected to the output end of the first cylinder 221. The first cylinder 221 pushes the first pushing block 222 to abut against both ends of the pipe 100. During loading (i.e., when the pipe 100 enters the pipe processing equipment), the pipe 100 can be moved by the moving mechanism 6 into the first positioning grooves 211 of the two first positioning blocks 21 to achieve support and positioning of the pipe 100. The two limiting components 22 push their respective first pushing blocks 222 against the two ends of the pipe 100 through their respective first cylinders 221 to limit the axial direction of the pipe 100. This limits the pipe 100 before it enters the trimming and stamping mechanism 3, ensuring that each pipe 100 that passes through the identification and positioning mechanism 2 enters the trimming and stamping mechanism 3 at the same position relative to it. This avoids the need for operators to clamp, position, and transfer the pipe 100, reducing the labor intensity and processing time of operators when loading materials.

[0083] Furthermore, the identification and positioning mechanism 2 includes two rollers 23, a motor, a second cylinder 24, and a ejector pin 25. The two rollers 23 are mounted on the first positioning block 21 and can clamp the tube 100. The motor is connected to the two rollers 23 and can drive the two rollers 23 to rotate. The second cylinder 24 is mounted on the frame 1. The ejector pin 25 is connected to the output end of the second cylinder 24. The second cylinder 24 pushes the ejector pin 25 into the inner wall of the tube 100 to identify the position of the welding wire in the inner wall of the tube 100. The motor drives two rollers 23 to rotate. The tube 100, which is clamped between the two rollers 23, rotates around its own axis due to the action of the rollers 23. The second cylinder 24 drives the ejector pin 25 to extend into the inner wall of the tube 100. When the ejector pin 25 contacts the weld line position on the inner wall of the tube 100, it moves, thereby identifying the position of the weld line in the inner wall of the tube 100. This ensures that when the trimming and stamping mechanism 3 stamps the tube 100, the tube 100 can be adjusted to a reasonable position (i.e., the weld line position on the inner wall of the tube 100 will not be squeezed after being stamped by the trimming and stamping mechanism 3).

[0084] It should be noted that, given that the method by which the second cylinder 24 and the ejector pin 25 of the identification and positioning mechanism 2 identify the weld lines on the inner wall of the tube 100 is a mechanical structure widely known to those skilled in the art, it will not be described in detail here to avoid being verbose. Only the necessary textual description is provided to ensure that those skilled in the art can effectively implement it based on this information.

[0085] Figure 4 This diagram shows a partial structural schematic of the edge-trimming and stamping mechanism 3 provided in this embodiment. Figure 5 A schematic diagram of another part of the edge-trimming and stamping mechanism 3 provided in this embodiment is shown. For example... Figure 4 and Figure 5 and combined Figures 1-3 As shown, the trimming and stamping mechanism 3 includes a first lower die 31, a first upper die 32, and a third cylinder 33. It has a first receiving groove 311 for placing the identified first work-to-be 101 and a second receiving groove 312 for placing the identified second work-to-be 102. It also has a stamping groove 321 for stamping the identified first work-to-be 101 and the identified second work-to-be 102. The third cylinder 33 is mounted on the frame 1. After being identified by the identification and positioning mechanism 2, the pipe 100 is moved by the moving mechanism 6 to above the first lower die 31. Under the movement of the moving mechanism 6, the first part to be processed 101 after identification falls into the first receiving groove 311, and the second part to be processed 102 after identification falls into the second receiving groove 312. The third cylinder 33 drives the first upper die 32 to approach the first lower die 31. After the first upper die 32 approaches the first lower die 31, the stamping groove 321 and the first receiving groove 311 cooperate to squeeze the first part to be processed 101 after identification (i.e., when the first upper die 32 and the second upper die are closed). At the same time, the stamping groove 321 and the second receiving groove 312 cooperate to squeeze the second part to be processed 102 after identification, thereby realizing the stamping operation of the first part to be processed 101 and the second part to be processed 102 of the pipe 100.

[0086] Furthermore, the trimming and stamping mechanism 3 also includes a first positioning and adjusting assembly 34 mounted on the frame 1. The first positioning and adjusting assembly 34 includes a first fixing block 341, a first adjusting rod 342, a first adjusting bolt 343, a fourth cylinder 344, and a second pushing block 345. The first fixing block 341 is mounted on the first lower die 31. The first adjusting rod 342 passes through the first lower die 31 and abuts against the identified second processing part 102. The first adjusting bolt 343 passes through the first fixing block 341 and abuts against the first adjusting rod 342. The fourth cylinder 344 is mounted on the frame 1. The second pushing block 345 is connected to the output end of the fourth cylinder 344. Specifically, by adjusting the length of the first adjusting rod 342 passing through the first lower die 31, the fourth cylinder 344 pushes the second pushing block 345 to move and abut against the identified first processing part 101 before the first upper die 32 and the first lower die 31 approach each other. This limits the tube 100 before the first upper die 32 and the first lower die 31 close, reducing the possibility of the tube 100 moving when the first upper die 32 and the first lower die 31 close, thereby ensuring the stamping quality of the tube 100. Furthermore, since the lengths of tubes 100 for different purposes are not entirely the same, the first adjusting rod 342 can be used for adjustment, allowing the trimming stamping mechanism 3 to adapt to tubes 100 of different lengths and abut against the identified second processing part 102, thereby keeping the identified first processing part 101 in the first receiving groove 311, thus improving the applicability of the trimming stamping mechanism 3.

[0087] Figure 6 This embodiment shows a partial structural schematic diagram of the punching mechanism 4 provided. Figure 7 A schematic diagram of another part of the punching mechanism 4 provided in this embodiment is shown. For example... Figure 6 and Figure 7 and combined Figures 1-5As shown, the punching mechanism 4 includes a second lower die 41, a second upper die, a buffer assembly 423, a fifth cylinder 424, and a sixth cylinder 425. The second lower die 41 has a third receiving groove 411 for the first part to be processed 101 after punching. The second upper die includes a first sub-die 421 and a second sub-die 422. The first sub-die 421 has a first receiving groove 4211 for accommodating the first part to be processed 101 after punching, and a punch disposed within the first receiving groove 4211 and capable of passing through the first part to be processed 101 after punching. The second sub-die 422 has a second receiving groove for accommodating the second part to be processed 102 after punching. The buffer assembly 423 supports the support material 100 and maintains a certain distance between the first part to be processed 101 after punching and the first receiving groove 4211. The fifth cylinder 424 is mounted on the frame 1. The sixth cylinder 425 is mounted on the frame 1. Among them, the fifth cylinder 424 can drive the first sub-mold 421 to approach the second lower mold 41, and after the first sub-mold 421 approaches the second lower mold 41, it causes the punch to pass through the first processing part 101 after stamping to perform punching, and the sixth cylinder 425 can drive the second sub-mold 422 to approach the buffer assembly 423. After being stamped, the tube 100 is moved by the moving mechanism 6 to above the second lower die 41 and the buffer assembly 423. The moving mechanism 6 places the first part to be processed 101 after being stamped into the third receiving groove 411 and places the second part to be processed 102 after being stamped onto the buffer assembly 423. The fifth cylinder 424 drives the first sub-die 421 of the second upper die to approach the second lower die 41. After the first sub-die 421 approaches the second lower die 41, the first sub-die 421 and the second lower die 41 close to limit the first part to be processed 101 after being stamped. The sixth cylinder 425 drives the second sub-die 422 of the second upper die to approach the buffer assembly 423 to limit the second part to be processed 102 after being stamped. The fifth cylinder 424 then pushes the punch to extend into the first part to be processed 101 after being stamped, thereby realizing the punching operation on the first part to be processed 101 after being stamped. The buffer assembly 423 can raise the tube 100 before the punch punches the first part to be processed 101 after punching, so as to provide a buffering effect when the punch punches.

[0088] Further, the buffer assembly 423 includes a first support block 4231, a second support block 4232, a first guide bolt, a first spring 4233, a second guide bolt 4234, and a second spring 4235. The first support block 4231 supports the second part to be processed 102 after stamping. The second support block 4232 is disposed between the second lower die 41 and the first support block 4231, and is used for the tube 100 between the first part to be processed 101 and the second part to be processed 102 after stamping. The first guide bolt passes through the first support block 4231 and is threadedly connected to the frame 1. The first spring 4233 is sleeved on the first guide bolt, and its two ends abut against the frame 1 and the first support block 4231 respectively. The second guide bolt 4234 passes through the second support block 4232 and is threadedly connected to the frame 1. The second spring 4235 is sleeved on the second guide bolt 4234, with its two ends abutting against the frame 1 and the second support block 4232, respectively. The first spring 4233, in its extended state, keeps the top of the first support block 4231 above the third receiving groove 411, and the second spring 4235, in its extended state, keeps the top of the second support block 4232 above the third receiving groove 411. When the second upper die and the second lower die 41 are closed, the second upper die compresses the pipe 100, and the first spring 4233 and the second spring 4235 are compressed by the pressure of the second upper die. This provides a buffering effect during punching of the pipe 100, reducing the impact and damage to the pipe 100 during punching, thereby protecting the surface quality and integrity of the pipe 100. The first guide bolt and the second guide bolt 4234 can maintain the stability of the first support block 4231 and the second support block 4232 when their respective first spring 4233 and second spring 4235 are deformed, preventing the first support block 4231 or the second support block 4232 from shifting due to spring deformation, thus losing its supporting function for the pipe 100.

[0089] Furthermore, the punching mechanism 4 also includes a third positioning adjustment assembly 43 mounted on the frame 1. The third positioning adjustment assembly 43 includes a movable frame 431 mounted on the frame 1 for placing the sixth cylinder 425, a ninth cylinder 432 mounted on the frame 1, and a fourth push block 433 connected to the output end of the ninth cylinder 432. The frame 1 has a waist-shaped hole along the axial direction of the tube 100. The movable frame 431 is located in the waist-shaped hole so that the movable frame 431 can move relative to the frame 1 along the axial direction of the tube 100. This allows the movable frame 431 to be adjusted to abut against the second end after stamping. The ninth cylinder 432 can push the fourth push block 433 to abut against the first end after punching. This limits the tube 100 before the second upper die and the second lower die 41 are closed, reducing the possibility of the tube 100 moving when the second upper die and the second lower die 41 are closed. This ensures the stamping quality of the tube 100. The movable frame 431 is also adapted to tubes 100 of different lengths for adaptive adjustment, thereby improving the applicability of the punching mechanism 4.

[0090] Figure 8 This embodiment shows a partial structural schematic diagram of the drilling mechanism 5 provided. Figure 9 A schematic diagram of another part of the drilling mechanism 5 provided in this embodiment is shown. Figure 8 and Figure 9 and combined Figures 1-7 As shown, the drilling mechanism 5 includes a third lower die 51, a third upper die 52, a third support block 53, and a drill bit 55. The third lower die 51 has a fourth receiving groove 511 for placing the first work-to-be-processed portion 101 after punching. The third support block 53 has a fifth receiving groove 531 for placing the tube 100 between the first work-to-be-processed portion 101 after punching and the second work-to-be-processed portion 102 after stamping. A seventh cylinder 54 is mounted on the frame 1 and can drive the third upper die 52 to abut against the tube 100. The drill bit 55 can pass through the second work-to-be-processed portion 102 after stamping to perform drilling. The moving mechanism 6 moves the punched pipe 100 above the third lower die 51 and places the punched first processing part 101 into the fourth receiving groove 511. The part between the punched first processing part 101 and the stamped second processing part 102 is placed in the fourth receiving groove 511. The first upper die 32 abuts against the pipe 100 under the push of the seventh cylinder 54, thereby achieving the purpose of limiting the pipe 100 to maintain the stability of the pipe 100 during the drilling process.

[0091] Furthermore, the drilling mechanism 5 also includes a second positioning adjustment assembly 56, which includes a second fixing block 561, a second adjusting rod 562, a second adjusting bolt 563, a third pushing block 564, and an eighth cylinder 565. The second fixing block 561 is mounted on the frame 1. The second adjusting rod 562 passes through the second fixing block 561 and abuts against the second processing section 102 after punching. The second adjusting bolt 563 passes through the second fixing block 561 and abuts against the second adjusting rod 562. The third pushing block 564 is located on one side of the first processing section 101 after punching. The eighth cylinder 565 can push the third pushing block 564 to move, causing the third pushing block 564 to press the tube 100 against the second adjusting rod 562. By adjusting the length of the second adjusting rod 562 passing through the first lower die 31, the eighth cylinder 565 pushes the third pushing block 564 to move to abut against the first processing part 101 after punching before the third upper die 52 abuts against the tube 100. This limits the tube 100 before the third upper die 52 abuts against the tube 100, reducing the possibility of movement of the tube 100 during drilling and ensuring the drilling quality of the tube 100. Furthermore, since different tubes 100 have different lengths, the second adjusting rod 562 can be used for adjustment, allowing the drilling mechanism 5 to adapt to tubes 100 of different lengths to abut against the second processing part 102 after punching. This keeps the first processing part 101 after punching in the fourth receiving groove 511, thereby improving the applicability of the drilling mechanism 5.

[0092] Figure 10 A schematic diagram of the moving mechanism 6 provided in this embodiment is shown. Figure 10 and combined Figures 1-9 As shown, the moving mechanism 6 consists of multiple clamp-type material handling robots 61 or suction-type material handling robots mounted on the frame 1, thereby enabling the pipe 100 to be moved onto the identification and positioning mechanism 2, the edge cutting and stamping mechanism 3, the punching mechanism 4, or the drilling mechanism 5.
