Description

Technical Field

[0001] This application relates to the field of rolling processing technology, and more specifically, to a rolling forming mold, apparatus and method. Background Technology

[0002] With the increasing number of 1U, 2U, and 4U server expansion units, the quality requirements for chassis are becoming more stringent. The internal structural components are also becoming more complex, and the fit between these components is becoming increasingly tight. For example, if one component needs to rotate with another via a hinge, this requires a rolled feature on one of the components; alternatively, the edges of the components can be rolled to prevent sharp edges from scratching hands and to increase strength. Therefore, further control is needed over the rolling process of chassis structural components. Firstly, it's crucial to ensure the dimensional stability of the rolled shape to meet the functional requirements of the fit between components. Secondly, it's essential to ensure a smooth, mold-free appearance after rolling to meet quality standards. Some rolled features also need to be further formed on the bending edge. However, the existing mold bending and rolling structure forming process has many steps, generally requiring four steps to complete. The process is relatively complex, which will increase the number of mold stations accordingly. This will increase the cost of the mold itself and the processing cost. Subsequent mold maintenance is also very cumbersome, and the dimensions are not easy to control. For production, it will also increase the demand for manpower and equipment, and the flow to the next station will also increase the time investment. Moreover, for the structural parts themselves, whether it is dimensional tolerance control or transportation between the forming stations, the probability of appearance defects is unavoidable.

The lower mold forming block is disposed on the lower pad, and the elastic element is disposed between the lower pressure block and the lower pad, so that the top surface of the lower pressure block is not lower than the top surface of the lower mold forming block in the initial state, and in the initial state, the bottom surface of the rolling forming block is higher than the bottom surface of the upper mold forming block.

[0005] In one exemplary embodiment, the rolling forming block and the upper die forming block are adjacent to each other; and / or the lower die forming block and the lower pressure block are adjacent to each other.

[0006] In one exemplary embodiment, the upper mold forming block has a strip-shaped notch on one side adjacent to the roll forming block, the width of which is the same as the distance from the semi-circular notch to the side of the roll forming block adjacent to the upper mold forming block.

[0007] In one exemplary embodiment, a semi-circular notch and a quarter-circular notch are arranged vertically correspondingly, and the diameter of the semi-circular notch is the same as the radius of the quarter-circular notch.

[0008] In one exemplary embodiment, a roller is provided at the semi-circular notch; and / or a roller is provided at the quarter-circular notch.

[0009] In one exemplary embodiment, there are multiple rollers, which are spaced circumferentially along the semi-circular notch and / or quarter-circular notch.

[0010] According to another embodiment of this application, a rolling forming apparatus is also provided, including the above-mentioned rolling forming mold, and an upper mold assembly and a lower mold assembly arranged correspondingly above and below. The upper mold assembly and the lower mold assembly are adjustable in position by a guide post mechanism. The upper mold assembly includes an upper mold base, a fixed plate, and an upper template. The fixed plate and the upper template are respectively connected to the upper mold base. There is a preset distance between the fixed plate and the upper template. The upper mold forming block is embedded in the upper template, and one end of the rolling forming block is connected to the fixed plate, and the other end is embedded in the upper template. The lower mold assembly includes a lower mold base, and a lower pad is arranged on the lower mold base. The upper mold assembly moves downward to close the rolling forming mold to bend and roll the workpiece.

[0011] In an exemplary embodiment, the upper mold assembly further includes an upper pad and a middle back plate. The upper pad is disposed between the upper mold base and the fixing plate and is connected to the upper mold base. The middle back plate is disposed on the upper mold plate and has a preset distance between it and the fixing plate. The roll forming block passes through the middle back plate.

[0012] In one exemplary embodiment, the upper mold assembly further includes an adjusting member disposed between the upper mold base and the middle back plate, the adjusting member being height-adjustable for adjusting a preset distance.

[0013] In one exemplary embodiment, the lower mold assembly further includes a lower template, which is disposed on a lower pad, and the lower mold forming block and the lower pressure block are both embedded in the lower template.

This can realize bending and rolling forming in one step without additional steps. Therefore, it can solve the problem of the complicated bending and rolling forming steps in the prior art, and achieve the effect of greatly reducing the bending and rolling forming steps and reducing production costs.

[0028] The embodiments of this application will be described in detail below with reference to the accompanying drawings and examples.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0030] To address the problem of complex bending and rolling forming steps in existing technologies, this application provides a rolling forming mold and a rolling forming apparatus. The rolling forming apparatus includes the rolling forming mold.

[0031] like Figures 1 to 7 As shown, the rolling forming mold includes a rolling forming block 13, an upper forming block 14, a lower backing plate 7, a lower forming block 15, a lower pressure block 16, and an elastic element 18. The rolling forming block 13 and the lower forming block 15 are arranged vertically correspondingly, and the upper forming block 14 and the lower pressure block 16 are also arranged vertically correspondingly. The bottom end of the rolling forming block 13 has a semi-circular notch, and the top end of the lower forming block 15 has a quarter-circular notch. The lower forming block 15 is disposed on the lower backing plate 7, and the elastic element 18 is disposed between the lower pressure block 16 and the lower backing plate 7, so that the top surface of the lower pressure block 16 is not lower than the top surface of the lower forming block 15 in the initial state. In the initial state, the bottom surface of the rolling forming block 13 is higher than the bottom surface of the upper forming block 14.

[0032] Using the rolling forming mold of this application, through the mutual cooperation of the rolling forming block 13, the upper mold forming block 14, the lower mold forming block 15 and the lower pressure block 16, the upper mold forming block 14 and the rolling forming block 13 only need to move downward to press the workpiece 17 to be processed, and the bending and rolling forming can be completed in sequence. This can realize the bending and rolling forming in one step without additional steps, which can simplify the forming process, reduce mold costs, reduce manpower and material consumption, make maintenance more convenient, and increase efficiency. The workpiece 17 is easier to meet the dimensional requirements after processing, so that the workpiece 17 is easier to assemble and meet the quality requirements.

[0033] like Figures 2 to 7 As shown, in this embodiment, the workpiece 17 to be processed includes a first segment 171 and a second segment 172 connected in sequence. In the initial state, the workpiece 17 to be processed is placed horizontally, with the first segment 171 placed on the lower pressing block 16 and the second segment 172 located above the lower die forming block 15. Furthermore, the height of the lower pressing block 16 is less than the height of the lower die forming block 15. Therefore, an elastic element 18 needs to be provided at the bottom of the lower pressing block 16 so that in the initial state, the top surface of the lower pressing block 16 is not lower than the top surface of the lower die forming block 15. This allows the upper die forming block 14 to contact the first segment 171 and the lower pressing block 16 first when it moves downward. Then, during the continued downward pressing process, the second segment 172 contacts the lower die forming block 15 and is bent, ensuring that the workpiece 17 to be processed can be bent normally.

[0034] It is understandable that the first segment 171 of the workpiece to be processed is a fixed segment, and the second segment 172 is a bending segment and a rolling segment.

[0035] In this embodiment, the bottom surface of the roll forming block 13 is set to be higher than the bottom surface of the upper mold forming block 14 in the initial state in order to provide space for bending processing, so that the roll forming mold first bends the workpiece 17 to be processed and then rolls it into shape.

[0036] In this embodiment, the rolling forming block 13 and the upper die forming block 14 are adjacent to each other, that is, the rolling forming block 13 and the upper die forming block 14 move up and down along each other's side. Correspondingly, the lower die forming block 15 and the lower pressing block 16 are adjacent to each other, that is, the lower pressing block 16 moves up and down along the side of the lower die forming block 15.

[0037] In this embodiment, the upper mold forming block 14 has a strip-shaped notch on one side adjacent to the rolling forming block 13. The width of the strip-shaped notch is the same as the distance from the semi-circular notch to the side edge of the rolling forming block 13 adjacent to the upper mold forming block 14. This arrangement ensures that the second segment 172, after bending, corresponds precisely to the edge of the semi-circular notch on the rolling forming block 13, facilitating subsequent rolling forming. Furthermore, the unnotched portion at the bottom of the upper mold forming block 14 forms a limiting portion. When the rolling forming block 13 moves downwards to abut against the limiting portion, it also abuts against the top surface of the lower mold forming block 15, thus completing the rolling forming step.

[0038] In this embodiment, the semi-circular notch and the quarter-circular notch are arranged vertically and vertically, and the diameter of the semi-circular notch is the same as the radius of the quarter-circular notch. Furthermore, the quarter-circular notch is located at the corner of the lower die forming block 15 near the lower pressure block 16. This arrangement ensures that after the second segment 172 rolls into a semi-circle at the semi-circular notch, it can then precisely enter the quarter-circular notch to complete the rolling of the remaining semi-circle, thus guaranteeing the smooth completion of the entire rolling process.

[0039] In this embodiment, a roller is provided at the semi-circular notch. Correspondingly, a roller is also provided at the quarter-circular notch. Specifically, there are multiple rollers, which are spaced apart circumferentially along the semi-circular and / or quarter-circular notches. By providing rollers, the workpiece 17 can pass through the semi-circular and quarter-circular notches more smoothly, reducing friction between the workpiece 17 and the notches, making the rolling process smoother, reducing mold marks on the product, and improving the appearance to meet quality requirements.

[0040] In this embodiment, three rollers are provided at the semi-circular notch, with the three rollers located at the two side openings and the bottom of the semi-circular notch, respectively. Correspondingly, two rollers are provided at the quarter-circular notch, with the two rollers located at the two side openings of the quarter-circular notch, respectively. This allows the workpiece 17 to contact the rollers first when entering the semi-circular and quarter-circular notches, thus enabling it to enter and move more smoothly within the semi-circular and quarter-circular notches.

[0041] In this embodiment, the elastic element 18 is a spring.

[0042] like Figure 8 As shown, this application also provides a rolling forming method, which uses the above-mentioned rolling forming mold to implement the rolling forming method. The rolling forming method includes: placing the workpiece 17 to be processed on the lower pressure block 16 and the lower mold forming block 15; closing the rolling forming mold, the upper mold forming block 14 moving downward to press the first segment 171 of the workpiece 17 to be processed and the lower pressure block 16, so that the second segment 172 of the workpiece 17 to be processed contacts the lower mold forming block 15 and bends upward; the rolling forming block 13 moving downward to press the second segment 172, so that the end of the second segment 172 enters the semi-circular notch and is rolled into a semi-circle; the rolling forming block 13 continuing to move downward to press the second segment 172, so that the end of the second segment 172 enters the quarter-circle notch and is rolled into a circle, thus completing the rolling forming.

[0043] Specifically, such as Figure 2 As shown, in the initial state, the top surface of the lower pressure block 16 is at least not lower than the top surface of the lower die forming block 15 under the elastic force of the elastic member 18, and the bottom surface of the upper die forming block 14 is lower than the bottom surface of the rolling forming block 13. The workpiece 17 to be processed is placed horizontally in the middle of the rolling forming mold, wherein the first segment 171 is placed on the lower pressure block 16, and the second segment 172 is located above the lower die forming block 15.

[0044] like Figures 3 to 4As shown, the upper die forming block 14 moves downward to press and fix the first segment 171. The horizontal distance between the limiting part of the upper die forming block 14 and the side edge of the lower pressure block 16 is the same as the thickness of the workpiece 17 to be processed, so that after the upper die forming block 14 continues to move downward, the second segment 172 is bent at 90°. At this time, the elastic member 18 is compressed to the limit position, and the upper die forming block 14 no longer moves downward. Then the rolling forming block 13 moves downward, so that the end of the second segment 172 enters the semi-circular notch.

[0045] like Figures 5 to 7 As shown, the rolling forming block 13 continues to move downwards, pressing the second segment 172, causing the second segment 172 to move along the semi-circular notch and roll up to form a semi-circle. The rolling forming block 13 continues to move downwards, causing the end of the second segment 172 to enter the quarter-circle notch and move along the quarter-circle notch, thereby rolling up to form a complete circle.

[0046] After bending and rolling are completed, the rolling forming block 13 and the upper die forming block 14 move upward, and the lower pressing block 16 returns to its initial state under the elastic force of the elastic element 18, so as to facilitate the processing of the next workpiece 17.

[0047] like Figure 1 As shown, this application also provides a rolling forming apparatus, including the aforementioned rolling forming mold, and an upper mold assembly and a lower mold assembly arranged correspondingly above and below. The upper mold assembly and the lower mold assembly are adjustable in position via a guide post mechanism 11. The upper mold assembly includes an upper mold base 1, a fixing plate 3, and an upper template 5. The fixing plate 3 and the upper template 5 are respectively connected to the upper mold base 1, and there is a preset distance between the fixing plate 3 and the upper template 5. An upper mold forming block 14 is embedded in the upper template 5, and one end of the rolling forming block 13 is connected to the fixing plate 3, while the other end is embedded in the upper template 5. The lower mold assembly includes a lower mold base 8, and a lower pad 7 is disposed on the lower mold base 8. The upper mold assembly moves downward to close the rolling forming mold to bend and roll the workpiece 17.

[0048] It should be noted that the upper mold forming block 14 is embedded in the upper template 5, meaning that the upper template 5 has a receiving groove for accommodating the upper mold forming block 14. The other end of the rolling forming block 13 is embedded in the upper template 5, meaning that the upper template 5 has a through hole so that the rolling forming block 13 can pass through the upper template 5.

[0049] In this embodiment, the guide post mechanism 11 includes a guide post and a guide sleeve. The guide post is disposed at one end of the lower mold base 8 and at the corresponding end of the upper mold base 1. The guide sleeve is nested with the guide post and is lifted and lowered through a chain structure, thereby driving the upper mold assembly to move up and down relative to the lower mold assembly.

[0050] like Figure 1As shown, the upper mold assembly also includes an upper pad 2 and a middle back plate 4. The upper pad 2 is disposed between the upper mold base 1 and the fixing plate 3 and is connected to the upper mold base 1. The middle back plate 4 is disposed on the upper template 5 and has a preset distance between it and the fixing plate 3. The roll forming block 13 passes through the middle back plate 4. Specifically, the middle back plate 4 has through holes so that the roll forming block 13 can pass through the middle back plate 4.

[0051] like Figure 1 As shown, the upper mold assembly also includes an adjusting member 19. The adjusting member 19 is disposed between the upper mold base 1 and the middle back plate 4, and its height is adjustable to adjust the aforementioned preset distance. It can be understood that the aforementioned preset distance is the processing stroke of the rolled forming block 13. Through the adjusting member 19, the aforementioned preset distance can be reasonably adjusted according to processing requirements, thereby adjusting the processing stroke of the rolled forming block 13. Specifically, the adjusting member 19 has an X-shaped telescopic structure, with its top and bottom abutting against the upper mold base 1 and the middle back plate 4 respectively. When the adjusting member 19 retracts inward, its height increases; when the adjusting member 19 extends outward, its height decreases, thereby adjusting the aforementioned preset distance.

[0052] like Figure 1 As shown, the lower mold assembly also includes a lower template 6, which is disposed on the lower pad 7. The lower mold forming block 15 and the lower pressing block 16 are both embedded in the lower template 6.

[0053] like Figure 1 As shown, the rolling forming device also includes two limiting members 12. The two limiting members 12 are respectively arranged facing each other on the upper mold base 1 and the lower mold base 8. When the two limiting members 12 abut against each other, the rolling forming device reaches the limit processing position.

[0054] like Figure 1 As shown, the rolling forming device also includes a pad 9 and a base 10. The pad 9 is connected to the base 10 and the lower mold base 8 respectively, and is used to adjust the height of the rolling forming device.

[0055] When the rolling forming device is running, the upper mold assembly and the lower mold assembly are guided by the guide post mechanism 11 to begin closing. That is, the upper mold assembly moves downward, which in turn drives the rolling forming block 13 and the upper mold forming block 14 of the rolling forming mold to move downward. The upper mold forming block 14 first contacts the workpiece 17 to be processed, and then slowly contacts the lower pressure block 16, pressing and fixing the first section 171 of the workpiece 17 to be processed. The second section 172 of the workpiece 17 to be processed also gradually contacts the lower mold forming block 15 and slowly slides around the roller of the lower mold forming block 15 to form. As the upper mold assembly continues to move downward, the upper mold forming block 14 gradually moves down. With the cooperation of the upper mold forming block 15, the second section 172 of the workpiece 17 to be processed is also slowly bent. After the lower pressure block 16 contacts the lower pad 7, the second section 172 of the workpiece 17 to be processed completes the 90° bend forming.

[0056] As the mold gradually closes, the rolling forming block 13 moves downwards in sync. Since the workpiece 17 has already been bent at 90° in the previous step, the first segment 171 is in a crushed state, and the second segment 172 begins to slowly contact the roller of the rolling forming block 13. Then the rolling forming block will roll slowly around the semi-circular notch of the rolling forming block 13, and in sync with the roller embedded in the semi-circular notch, it will slowly roll and form.

[0057] As the mold continues to close, the second segment 172 will again come into contact with the roller of the lower mold forming block 15. The second segment 172 continues to gradually form around the quarter-circle notch of the lower mold forming block 15 with the roller, eventually completing the rolling and forming process.

[0058] When the mold opens and closes, the rolling forming block 13 moves upward with the upper mold assembly, and the upper mold forming block 14 and the lower pressing block 16 will gradually separate. The workpiece 17 completes one bending and rolling forming process, and each forming block returns to its initial state.

[0059] From the above description, it can be seen that the above embodiments of this application achieve the following technical effects: By using the rolling forming mold of this application, through the mutual cooperation of the rolling forming block 13, the upper mold forming block 14, the lower mold forming block 15 and the lower pressure block 16, the upper mold forming block 14 and the rolling forming block 13 only need to move downward to press the workpiece 17 to be processed, and the bending and rolling forming can be completed in sequence. In this way, bending and rolling forming can be completed in one step without additional steps. This simplifies the forming process, reduces mold costs, reduces manpower and material consumption, makes maintenance more convenient, and is more efficient. The workpiece 17 is easier to meet the size requirements after processing, so that the workpiece 17 is easier to assemble and meet the quality requirements.

[0060] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this application should be included within the protection scope of this application.
