Description

Technical Field

[0001] The utility model relates to the technical field of hemming machines, in particular to an assembled laboratory air duct prefabrication hemming machine. Background Art

[0002] The hemming machine is a device that uses working rollers to bend sheet metal. It can form parts of different shapes, such as cylindrical parts and conical parts. It is a very important processing equipment. The working principle of the hemming machine is to move the working rollers through the action of hydraulic, mechanical and other external forces, so as to form the bent plate or roll.

[0003] The air duct is a piping system used for air transportation and distribution. For the production process of circular air ducts, rolling machines are mostly used. However, traditional rolling machines usually only have a single processing unit, resulting in low processing efficiency of the air duct. For this reason, we provide an assembled laboratory air duct prefabrication rolling machine to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and to provide an assembled laboratory air duct prefabrication rolling machine, which adopts multiple stations to roll the air duct at the same time, effectively improving work efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled laboratory air duct prefabricated rolling machine, comprising a base plate, a fixed rolling mechanism is arranged on the upper part of the base plate, the fixed rolling mechanism comprises two chassis rotating on the upper surface of the base plate, the upper surface of the base plate is fixedly connected to two columns, a mounting plate is installed on the upper surface of the column, a servo motor is installed on the upper surface of the mounting plate, the output shaft of the servo motor passes through the mounting plate and extends to the lower part of the mounting plate, the output shaft of the servo motor is fixedly connected to a threaded rod, the outer surface of the threaded rod is threadedly connected to a screw ring, the outer surface of the screw ring is fixedly connected to two movable plates, two rotating motors are installed on the upper surface of the movable plate, the output shaft of each rotating motor is fixedly connected to a rotating pressure cylinder, and the upper surface of the base plate is rotatably connected to two rolling wheels.

[0006] Furthermore, two sleeves are fixedly connected to the upper surface of the mounting plate, and a sleeve rod is slidably connected to the interior of each sleeve. Two through rings are fixedly inlaid on the upper surface of the mounting plate. The bottom ends of the two sleeve rods respectively pass through the two through rings and extend to the lower part of the mounting plate, and the sleeve rods are slidably connected to the through rings. The bottom ends of the two sleeve rods are fixedly connected to the upper surface of the movable plate. The sleeve can limit the sleeve rod from reciprocating up and down movement inside the sleeve, thereby ensuring the stability of the movable plate during the up and down reciprocating movement, and effectively preventing the movable plate from deflecting during the movement, which may cause the movable plate to get stuck and affect the normal use of the rolling machine.

[0007] Furthermore, a bearing is fixedly embedded on the upper surface of the mounting plate, and the output shaft of the servo motor passes through the bearing and extends to the lower part of the mounting plate, and the inner ring of the bearing is fixedly connected to the outer surface of the output shaft of the servo motor, which can effectively reduce the friction between the output shaft and the mounting plate during the rotation of the servo motor, and avoid wear of the output shaft of the servo motor due to long-term use, thereby affecting the normal use of the servo motor.

[0008] Furthermore, a slip ring is fixedly connected to the top of each sleeve rod, and the slip ring is slidably connected to the inner wall of the sleeve, which can effectively improve the stability of the sleeve rod in the up and down position process, thereby preventing the sleeve rod from swinging inside the sleeve, thereby causing the movable plate to swing and affecting the normal use of the rolling machine.

[0009] Furthermore, a through hole is provided on the bottom surface of each sleeve, and the outer surface of the sleeve rod is slidably connected to the through hole, which effectively reduces the friction between the sleeve rod and the sleeve and avoids wear of the outer surface of the sleeve rod due to long-term use, thereby narrowing the diameter of the sleeve rod and causing the sleeve rod to shake inside the sleeve, affecting the use of the rolling machine.

[0010] Furthermore, the bottom surface of the mounting plate is fixedly connected to a support plate, and a storage bucket is installed on the front of the support plate. The mounting plate can cover the fixed rolling mechanism of the rolling machine to improve the aesthetics of the rolling machine. At the same time, the storage bucket can store some sundries to facilitate the use of the rolling machine.

[0011] Furthermore, a stabilizing plate is fixedly connected to the outer surfaces of the two sleeves, and the bottom surface of the stabilizing plate is fixedly connected to the upper surface of the servo motor. The stabilizing plate can fix the two sleeves at the same time, and the stabilizing plate can fix the servo motor, thereby improving the stability of the fixation of the servo motor and the two sleeves and avoiding shaking of the servo motor and the sleeve during use.

[0012] Compared with the existing technology, the prefabricated laboratory air duct hemming machine has the following beneficial effects:

[0013] 1. The utility model drives the threaded rod to rotate through a servo motor, and a screw ring and the threaded rod are in a threaded relationship. The screw ring drives two movable plates to move downward, and the movable plates push the rotating pressing cylinder to move downward to fix the cylindrical air duct. The rolling wheel is connected to the edge of the bottom end of the cylindrical air duct, and then the rotating motor drives the rotating pressing cylinder to rotate, so that the rotating pressing cylinder drives the cylindrical air duct to rotate. The cylindrical air duct is rolled under the rolling wheel, so that the whole can roll the cylindrical air ducts on both sides at the same time, effectively improving the working efficiency of the rolling machine.

[0014] 2. The utility model can effectively reduce the friction between the output shaft and the mounting plate during the rotation of the servo motor through the bearing, so as to avoid the wear of the output shaft of the servo motor due to long-term use, thereby affecting the normal use of the servo motor. The slip ring can effectively improve the stability of the sleeve rod in the up and down position process, so as to avoid the swing of the sleeve rod inside the sleeve, thereby causing the swing of the movable plate and affecting the normal use of the rolling machine. The through hole can effectively reduce the friction between the sleeve rod and the sleeve, so as to avoid the wear of the outer surface of the sleeve rod due to long-term use, thereby causing the sleeve rod diameter to narrow, causing the sleeve rod to shake inside the sleeve and affecting the use of the rolling machine.

Two through rings 206 are fixedly inlaid on the upper surface of the mounting plate 2012.
