Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel air duct processing, in particular to a high-efficiency stainless steel air duct bending machine. Background Art

[0002] Ducts are pipe systems used for air delivery and distribution. There are two types: composite ducts and inorganic ducts. They can be classified by cross-sectional shape and material. Stainless steel ducts are made by applying sealant (such as neutral glass glue) to the seams such as the seams of the bite, rivets, and the four corners of the flange. Metal ducts are made of various metal materials, including galvanized iron and stainless steel. With the continuous development of the storage tank industry, more and more industries and enterprises have used storage tanks, and more and more enterprises have entered the storage tank industry;

[0003] When stainless steel air ducts are used, they need to be bent. Existing bending machines cannot bend the stainless steel air ducts to a specified angle according to the use requirements, which results in low processing accuracy, low processing efficiency and high energy consumption.

[0004] The existing patent (Announcement No.: CN216137910U) is an energy-saving and efficient stainless steel duct bending machine. By setting a driving mechanism, a transmission gear and a transmission tooth chain, one end of the duct is inserted between the upper pressure roller and the two support rollers, and the driving motor is started to drive the driving wheel to rotate. Since the driving wheel is transmitted to the driven wheel through the transmission belt, the rotating rod fixed to the driven wheel is driven to rotate. Since the two transmission gears are transmitted through the transmission tooth chain, the two rotating rods are driven to rotate in the same direction. At this time, the duct can be driven for transportation and bending processing. It has a simple structure, high processing efficiency, low energy consumption and easy maintenance.

[0005] Although the above patent can improve the efficiency of bending processing to a certain extent, it still has certain limitations, namely, there is a lack of fixation of the air duct during the bending process of the air duct, which seriously affects the bending and forming effect of the air duct. Summary of the invention

[0006] The utility model aims to provide a high-efficiency stainless steel air duct bending machine, which can solve the problem of poor air duct forming caused by lack of air duct fixation.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an efficient stainless steel duct bending machine, comprising a workbench, a processing groove is provided on the workbench, a mounting frame is fixedly installed on the top wall of the workbench, an electric cylinder is fixedly installed on the mounting frame, a pressure wheel is detachably installed on the output end of the electric cylinder, and slide grooves are symmetrically provided on the workbench, a first fixed block and a second fixed block are respectively slidably installed in the slide grooves, a first spring is fixedly installed between the side wall of the fixed block and the slide groove, and a linkage mechanism cooperating with the fixed block is provided on the workbench.

[0008] Preferably, the linkage mechanism includes a fixed rod fixedly mounted on the side wall of the first fixed block, a sliding groove is provided on the fixed rod, a piston rod is slidably mounted in the sliding groove, a second spring is fixedly mounted between the piston rod and the sliding groove, a clamping block is fixedly mounted on the side wall of the piston rod away from the fixed rod, and a driving mechanism cooperating with the piston rod is provided on the fixed rod.

[0009] Preferably, the driving mechanism comprises a coil embedded in a fixed rod, and the coil is electrically connected to the electric cylinder, and a magnet cooperating with the coil is embedded in the piston rod.

[0010] Preferably, a cavity is formed on the clamping block, air holes communicating with the outside are evenly formed on the side walls of the cavity, and an air pipe communicating with the slide groove is inserted on the side walls of the cavity.

[0011] Preferably, an iron core cooperating with the coil is embedded on the fixing rod.

[0012] Preferably, the sides of the clamping block and the second fixing block that are close to each other are both arc-shaped.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The present application sets a coil, and during the start-up process of the electric cylinder, the coil is energized and generates a magnetic field. Then, under the action of the magnetic field, the magnet drives the piston rod to move. During the movement of the piston rod, the clamping block is driven to move. During the movement of the clamping block, the air duct is driven to contact the second fixed block. Then, under the joint action of the second fixed block and the clamping block, the air duct is fixed, thereby effectively preventing the movement of the air duct from affecting the bending effect during the bending process of the air duct, thereby improving the bending effect of the air duct.

[0015] 2. In the present application, an air cavity is opened. When the piston rod drives the clamping block to approach the air duct, the air pressure in the slide groove on the side of the piston plate away from the clamping block is reduced and air is sucked in through the air pipe, cavity and air holes. When the side wall of the clamping block fits the air duct, the air duct and the clamping block are tightly sucked together under the action of air pressure, thereby improving the fixing effect of the air duct.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3 , the utility model provides a technical solution:

[0024] A high-efficiency stainless steel duct bending machine comprises a workbench 1, the workbench 1 is provided with a processing groove, a mounting frame 2 is fixedly installed on the top wall of the workbench 1, an electric cylinder 3 is fixedly installed on the mounting frame 2, a pressure wheel 4 is detachably installed on the output end of the electric cylinder 3, and a slide groove is symmetrically provided on the workbench 1, a first fixed block 5 and a second fixed block 6 are slidably installed in the slide groove respectively, a first spring 7 is fixedly installed between the side wall of the fixed block and the slide groove, and a linkage mechanism cooperating with the fixed block is provided on the workbench 1.

[0025] The linkage mechanism includes a fixed rod 8 fixedly mounted on the side wall of the first fixed block 5, a sliding groove is provided on the fixed rod 8, a piston rod 13 is slidably mounted in the sliding groove, a second spring 14 is fixedly mounted between the piston rod 13 and the sliding groove, a clamping block 15 is fixedly mounted on the side wall of the piston rod 13 away from the fixed rod 8, and a driving mechanism cooperating with the piston rod 13 is provided on the fixed rod 8.

[0026] The driving mechanism includes a coil 10 embedded in the fixing rod 8 , and the coil 10 is electrically connected to the electric cylinder 3 , and a magnet 9 matching with the coil 10 is embedded in the piston rod 13 .

[0027] By adopting the above technical solution, when in use, the steel pipe air duct is placed between the second fixed block 6 of the workbench 1 and the clamping block 15, and then the output end of the electric cylinder 3 extends and drives the pressure wheel 4 to move downward. In the process of the pressure wheel 4 moving downward, it gradually contacts the air duct and applies pressure to the air duct, and then the air duct is bent under the action of the pressure wheel 4, thereby achieving the purpose of bending the air duct.

[0028] During the startup of the electric cylinder 3, the coil 10 is energized and generates a magnetic field. Then, under the action of the magnetic field, the magnet 9 drives the piston rod 13 to move. During the movement of the piston rod 13, the clamping block 15 is driven to move. During the movement of the clamping block 15, the air duct is driven to contact the second fixed block 6. Then, under the joint action of the second fixed block 6 and the clamping block 15, the air duct is fixed, thereby effectively preventing the movement of the air duct during the bending process from affecting the bending effect, thereby improving the bending effect of the air duct.

[0029] Specifically, Figure 3 As shown, a cavity 11 is formed on the clamping block 15 , air holes communicating with the outside are evenly formed on the side wall of the cavity 11 , and an air pipe 12 communicating with the slide groove is inserted on the side wall of the cavity 11 .

[0030] By adopting the above technical solution, when the piston rod 13 drives the clamping block 15 to approach the air duct, the air pressure in the slide groove on the side of the piston plate away from the clamping block is reduced and air is sucked in through the air pipe 12, the cavity 11, and the air hole. When the side wall of the clamping block 15 fits the air duct, the air duct and the clamping block 15 are tightly sucked together under the action of air pressure, which improves the fixing effect of the air duct.

[0031] Specifically, Figure 3 As shown, an iron core 16 matching with the coil 10 is embedded on the fixing rod 8 .

[0032] By adopting the above technical solution, in the process of the coil 10 generating a magnetic field to drive the magnet 9 to move, the iron core 16 generates an induced magnetic field in the same direction as the magnetic field of the coil 10, and then the two magnetic fields are superimposed on each other, thereby increasing the magnetic force exerted on the magnet 9, that is, increasing the clamping force of the clamping block on the air duct, thereby improving the fixing effect of the air duct.

[0033] Specifically, Figure 1 As shown, the sides of the clamping block 15 and the second fixing block 6 that are close to each other are both arc-shaped.

[0034] By adopting the above technical solution, by making the sides of the clamping block 15 and the second fixing block 6 close to each other arc-shaped, the force area when the air duct is clamped can be increased, that is, the pressure on the air duct is reduced, thereby effectively preventing the air duct from being damaged.

[0035] Working principle: when in use, the steel pipe air duct is placed between the second fixed block 6 of the workbench 1 and the clamping block 15, and then the output end of the electric cylinder 3 extends and drives the pressure wheel 4 to move downward, and gradually contacts the air duct and applies pressure to the air duct during the downward movement of the pressure wheel 4, and then the air duct is bent under the action of the pressure wheel 4; during the starting process of the electric cylinder 3, the coil 10 is energized and generates a magnetic field, and then the magnet 9 drives the piston rod 13 to move under the action of the magnetic field, and the clamping block 15 is driven to move during the movement of the piston rod 13, and the air duct is driven to contact the second fixed block 6 during the movement of the clamping block 15, and then the air duct is fixed under the joint action of the second fixed block 6 and the clamping block 15; during the process of the piston rod 13 driving the clamping block 15 to approach the air duct, the air pressure on the side of the piston plate away from the clamping block in the slide groove is reduced and air is sucked through the air pipe 12, the cavity 11, and the air hole. When the side wall of the clamping block 15 fits the air duct, the air duct and the clamping block 15 are tightly sucked together under the action of the air pressure.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
