Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air duct manufacturing, in particular to an air duct interface pressing device. Background Art
[0002] Ventilation ducts are mostly assembled from sheet metal parts. In order to meet the needs of different working conditions, ventilation ducts are generally made of multiple duct heads spliced together. The two ends of a single duct are interfaces for connection. The interfaces of different types of ducts are divided into external interfaces and internal interfaces according to production requirements.
[0003] The external duct interface generally refers to the portion of the duct that connects to external equipment or piping. This interface may involve flanges, threads, or other mechanical connections to allow for connection to other system components. For example, an external interface is used when the duct may need to connect to an external unit in an air conditioning system. The internal duct interface refers to the interface that connects various internal components of the duct. These interfaces ensure smooth airflow within the duct system and typically require a good seal to prevent air leakage. Internal interfaces may use various methods, such as flanges, sockets, and threads.
[0004] When roll-forming duct joints, existing equipment for producing ducts typically only press-forms a single external or internal joint. It's impossible to form both internal and external joints on the same machine. This necessitates the use of multiple machines to form both the external and internal joints, which is not only time-consuming but also increases production costs. Furthermore, manual operation makes it difficult to ensure joint consistency and sealing. Utility Model Content

Therefore, the above terms cannot be understood as limiting the present invention.
[0027] In the description of this utility model, if the word "several" or "several" is used, it means one or more, and "more" means two or more. "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself.

[0028] The following is combined with Figure 1-6The embodiment of the air pipe interface compression device is further described in detail.
[0029] An air pipe interface compression device, as shown in Figure 1 、 2 and Figure 6 , comprises a machine table 1, the machine table 1 is sequentially provided with a guide mechanism 2, a rolling mechanism 3 and a re-pressing mechanism 4 along the feeding direction; the guide mechanism 2 is used for directing the galvanized steel plate to the rolling mechanism 3, and one side of the guide mechanism 2 is connected to the feeding end of the rolling mechanism 3; the rolling mechanism 3 is used for rolling and forming the galvanized steel plate, and the end of the rolling mechanism 3 is connected to the re-pressing mechanism 4; the re-pressing mechanism 4 is used for re-bending and shaping the rolled galvanized steel plate; and the re-pressing mechanism 4 comprises mounting brackets 41, connecting seats 42 connected to the mounting brackets 41, and re-pressing rollers 43 mounted on the connecting seats 42, the mounting brackets 41 are arranged on the machine table 1 corresponding to the end of the rolling mechanism 3, the connecting seats 42 are slidingly connected between the mounting brackets 41, a hollow passage 421 for conveying the galvanized steel plate is formed in the middle of the connecting seat 42, and an adjusting assembly 44 for adjusting the rolling position is further connected between the top end of the connecting seat 42 and the mounting bracket 41; the re-pressing rollers 43 are provided in two groups, and the two groups of re-pressing rollers 43 are arranged on the two sides of the hollow passage 421, respectively, a clamping gap for rolling the galvanized steel plate is arranged between each group of re-pressing rollers 43, and each group of re-pressing rollers 43 is arranged in an up-down manner and rotatingly connected to the connecting seat 42.
[0030] Specifically, the feeding direction can be selected according to the processing type of the air pipe interface; when the inner interface of the air pipe needs to be processed, the air pipe edge bending part is large, and the interface diameter is small, therefore, the galvanized steel plate is fed from the guide mechanism 2, and is rolled multiple times under the action of the rolling mechanism 3, so that the galvanized steel plate is rolled and formed into the shape of the inner interface of the air pipe, and finally output from the hollow passage 421 in the re-pressing mechanism 4 to the next process; in order to avoid the influence of the re-pressing rollers 43 on the galvanized steel plate rolled by the rolling mechanism 3, the position of the re-pressing rollers 43 can be adjusted by the adjusting assembly 44, so that the re-pressing rollers 43 and the galvanized steel plate do not interfere with each other; when the outer interface of the air pipe needs to be processed, the air pipe edge bending part is small, and the interface diameter is large, therefore, the galvanized steel plate is fed from the re-pressing mechanism 4, and the rolling mechanism 3 is reversely rotated and rolled, so that the galvanized steel plate is reversely rolled and formed into the shape of the outer interface under the action of the re-pressing mechanism 4 and the rolling mechanism 3; the formation of the outer interface and the inner interface is completed at one time, thereby reducing the equipment investment and the operation time, and reducing the production cost; at the same time, manual operation is reduced, and the interface forming time is significantly shortened.
[0031] Among them, the machine 1 is also provided with a control system 7, which is located on one side of the rolling mechanism 3, and the control system 7 is electrically connected to the guide mechanism 2, the rolling mechanism 3 and the re-pressing mechanism 4 respectively; the entire rolling process is completed under the control of the control system 7, and the control system 7 is used to detect the operating status of the equipment in real time, and adjust various rolling parameters according to production needs to ensure that the one-time rolling forming of the inner and outer interfaces of the air duct can be achieved at the same time.
[0032] In this embodiment, the adjustment assembly 44 includes an adjusting screw 441, a connecting block 442 and a lifting cylinder 443. The lifting cylinder 443 is fixedly connected to the top of the mounting bracket 41, and the output end of the lifting cylinder 443 is transmission-connected to the adjusting screw 441. The other end of the adjusting screw 441 is connected to the connecting block 442, and the connecting block 442 is clamped and fixed on the connecting seat 42.
[0033] Specifically, when the adjusting component 44 intervenes in the rolling position of the re-pressing mechanism 4, the adjusting screw 441 is driven by the lifting cylinder 443 to control the lifting and lowering of the connecting block 442. Since the connecting block 442 is fixed to the top of the connecting seat 42, the position of the re-pressing roller 43 is synchronously driven during the lifting and lowering process of the connecting block 442, so that the rolling interface type can be changed according to production needs.
[0034] In this embodiment, if Figure 3 、 4 As shown, the rolling mechanism 3 includes a fixed bracket 31, a shaft 32, a roller assembly 33 and a drive assembly 34. The fixed bracket is arranged parallel and symmetrically on the frame, and embedded holes are evenly opened on both sides of the fixed bracket. At least two bearing mounting seats 311 are embedded in a single embedded hole, and the two bearing mounting seats 311 are arranged up and down; the two ends of the shaft 32 are connected to the bearing mounting seats 311, and limiting rings 321 are provided on both sides of the shaft 32 close to the bearing mounting seats 311; there are multiple roller assemblies 33, and the multiple roller assemblies 33 are respectively mounted on the shaft 32 at the position of the limiting guide sleeve; the drive assembly 34 is connected to the shaft 32 to drive the multiple roller assemblies 33 to rotate synchronously to roll the workpiece.
[0035] Specifically, the roller assembly 33 includes an upper pressing roller 331 and a lower pressing roller 332. The upper pressing roller 331 has a flange 3311, while the lower pressing roller 332 has a groove 3321 that matches the flange 3311. A rolling gap is formed between the flange 3311 and the groove 3321 for the workpiece to pass through. The widths of the flange 3311 and the groove 3321 gradually decrease along the rolling direction of the roller 33. The flange 3311 and the groove 3321 cooperate to roll-form the galvanized steel sheet.
[0036] It is worth noting that in the present invention, the upper pressure roller 331 and the lower pressure roller 332 are both set in an even number, and in the present invention, they are specifically set to 10, in order to achieve bone pressure on the galvanized steel sheet during rolling; at the same time, the rolling mechanism 3 can achieve forward and reverse rotation. After changing the rotation direction according to processing needs, the internal and external interfaces of the galvanized steel sheet can be roll-formed. Among them, the driving component 34 includes a gear 341, a driven wheel 342 and a driving motor 343. There are multiple gears 341, and the multiple gears 341 are rotatably connected to one end of the shaft 32, and the gear 341 on the upper pressure roller 331 is meshed with the gear 341 on the lower pressure roller 332; the driving motor 343 is installed on one side of the fixed bracket through a bracket, and a pulley 344 is provided on the output end of the driving motor 343. The pulley 344 is connected to the driven wheel 342 through a belt drive, and the driven wheels 342 are equidistantly arranged on the shaft 32.
[0037] In this embodiment, a group of pressing rollers 5 are provided at one end of the fixed bracket corresponding to the guide mechanism 2 , the gaps between the pressing rollers 5 correspond to the rolling gaps, and one end of the pressing rollers 5 is separately connected to a driving member 6 .
[0038] Specifically, the purpose of setting the pressure roller 5 is to prevent the galvanized steel sheet from bending when the galvanized steel sheet is subjected to the rolling mechanism 3. At the same time, the pressure roller 5 is controlled to rotate by a separately connected driving member 6. The driving member 6 can adopt a cylinder or an electric cylinder, that is, it can control whether the pressure roller 5 is working according to demand. In order to simultaneously meet the requirement of maintaining a straight line when rolling the inner and outer interfaces of the air duct, another set of pressure rollers 5 can be synchronously set at one end of the rolling mechanism 3 close to the re-pressing mechanism 4. The rolling effect of the pressure roller 5 is utilized to keep the galvanized steel sheet flat when feeding.
[0039] In this embodiment, if Figure 5 As shown, the guide mechanism 2 includes a connecting bracket 21, a guide platform 22 and a limit bar 23. The connecting bracket 21 is fixed on the machine platform 1, and one side of the connecting bracket 21 is in contact with the fixed bracket; the guide platform 22 is fixed to the connecting bracket 21 by screws, and a plurality of guide holes 221 are horizontally opened on the guide platform 22; the limit bar 23 includes a fixed limit bar 231 and a movable limit bar 232. The fixed limit bar 231 and the movable limit bar 232 are arranged in parallel on the guide platform 22, and the movable limit bar 232 is movably connected in the guide hole 221.
[0040] Specifically, the guide mechanism 2 can avoid the problem of galvanized steel sheet bending during rolling in the process of guiding feeding or discharging, and uses the guide platform 22 to bear on the clamping gap position between the upper pressure roller 331 and the lower pressure roller 332, and sets a limit bar 23 on the guide platform 22 to limit and fix the galvanized steel sheet. The limit bar 23 on one side is a movable limit bar 232. The staff can rotate the fixed stud on the movable limit bar 232 according to the set rolling position of the edge of the galvanized steel sheet, so that the movable limit bar 232 can move along the direction of the guide hole 221, and then change the position between the fixed limit bar 231 and the movable limit bar 232; thereby, the placement position of the galvanized steel sheet in the feeding direction is adjusted, so that the two ends of the galvanized steel sheet can be aligned with the rolling gap under the blocking action of the limit bar 23, thereby ensuring the subsequent rolling quality.
[0041] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
