Description

Technical Field

[0001] This utility model belongs to the field of machining technology and relates to an improvement of a special non-ferrous metal processing equipment. Background Technology

[0002] After the aluminum profiles for the railcar body are produced, the top and bottom surfaces need to be manually ground and polished to meet customer requirements. After the top surface is polished, the bottom surface needs to be ground and polished as well. This requires manually flipping the entire aluminum profile 180 degrees. This process requires five workers working together: one person operates an overhead crane, using five evenly distributed slings to lift the aluminum profile approximately 1 meter off the ground; one person at each end manually holds the profile steady; and two people in the middle simultaneously manually flip one side of the profile. The two people at the beginning and end also work together with the two in the middle to rotate the profile 180 degrees, completing the flipping of a single aluminum profile. A single aluminum profile typically weighs over 200 kg. During this process, it's crucial to prevent the profile from flipping too quickly, increasing the risk of worker injury. The flipping process for a single profile often takes more than a minute. Therefore, manually flipping aluminum profiles is time-consuming, labor-intensive, requires a large workforce, and carries safety risks.

[0003] In summary, the problems with existing technologies are:

[0004] (1) Manual flipping of a single aluminum profile requires five workers to work together, which is a large number of people.

[0005] (2) The weight of a single aluminum profile is usually over 200kg, and the flipping work needs to be carried out slowly, which is time-consuming and laborious.

[0006] (3) During the aluminum profile flipping process, the entire profile needs to be rotated 180 degrees, which may cause workers to be crushed.

[0007] (4) Manually polishing the top and bottom of aluminum profiles is very troublesome. It requires workers to work with a hand-held polishing machine from beginning to end, which is time-consuming and laborious. It has poor continuous workability. After polishing an aluminum profile, workers need to rest and recover their strength before starting work again. Utility Model Content

[0008] The purpose of this invention is to provide an automatic turning and processing device for large-section aluminum profiles. The device uses a mechanical pressure arm to clamp and fix the aluminum profile, and a circular rotating wheel is responsible for turning the aluminum profile over, thereby realizing automatic grinding and improving work efficiency.

[0009] The technical solution of this utility model is as follows: a bottom track is welded and fixed to the bottom steel plate base in a longitudinal direction; semi-circular uprights are welded and fixed to both ends of the bottom steel plate base; four mechanical pressure arms responsible for clamping the aluminum profile are divided into upper and lower groups and symmetrically distributed; a circular hole structure is distributed at the tail and head of the mechanical pressure arm, with the tail hole through which the pressure arm rotating rod passes and the head hole through which the pressure arm reinforcing rod passes; a flexible rubber pad is fixed at the contact point between the mechanical pressure arm and the aluminum profile to ensure that the aluminum profile is not deformed by pressure and to ensure that the aluminum profile and the mechanical arm are tightly fixed together after clamping; the four pressure arm rotating rods are fixed by bearings. Fixed on the rotating wheel, the pressure arm rotating rod has rotating rod gear heads at both ends, which are driven by motors at both ends, and the motors are fixed on the motor bracket; the rotating wheel is built into the semi-circular frame and connected to the semi-circular frame through bearings. Its exterior has a ring of gear structure, which is driven by two motors at the bottom to achieve rotation; two bottom rails are symmetrically distributed, and the grinding machine frame rolls with the rails through electric wheels; the hydraulic system is installed on the grinding machine frame, and an electric grinding machine is installed at the bottom of the hydraulic system. The hydraulic rod and the electric grinding machine are connected together by pin holes and pins.

[0010] The beneficial effects of this invention are: it greatly reduces the number of workers required, requiring only one worker to operate the device to automatically grind and flip aluminum profiles. It shortens grinding and flipping time, increasing work efficiency by 30 times. Because this device does not require manual flipping of the aluminum profiles, there is no risk of workers being injured by crushed aluminum profiles. It also avoids the problem of excessive manual labor that prevents continuous operation. Attached Figure Description

[0012] Figure 2 This is the front view of this utility model;

[0013] Figure 3 This is a side view of the present invention. Detailed Implementation

[0014] The utility model will be further described below with reference to the accompanying drawings:

[0015] As shown in the figure, 1 is the mechanical pressure arm, 2 is the pressure arm rotating rod, 3 is the semi-circular upright frame, 4 is the rotating wheel, 5 is the rotating rod gear head, 6 is the motor, 7 is the motor bracket, 8 is the bottom track, 9 is the electric wheel, 10 is the overall bottom surface, 11 is the pressure arm reinforcing bar, 12 is the hydraulic system, 13 is the grinder upright frame, and 14 is the electric grinder.

[0016] 1. Mechanical pressure arm: The mechanical pressure arm is welded from 10mm thick steel plate. It is responsible for fixing and clamping the aluminum profile, and works with the pressure arm rotating rod to rotate and flip the aluminum profile. Its tail has a round hole connecting to the pressure arm rotating rod, and they are fully welded together. The head of the mechanical pressure arm has a round hole connecting to the pressure arm reinforcing bar, and they are directly fully welded together. A flexible rubber pad is distributed on the top surface of the mechanical pressure arm to ensure that the aluminum profile is not deformed by pressure, and also to ensure that the aluminum profile and the mechanical arm are tightly fixed together after clamping.

[0017] 2. The pressure arm rotating rod is made of 100mm diameter × 10mm thick steel pipe. It passes through the round hole at the tail of the mechanical pressure arm and is welded together. Its two ends are connected to the wheel hole via bearings, and rotating rod gear heads are distributed at both ends. The pressure arm rotating rod, together with the wheel hole bearings and rotating rod gear heads, forms a whole. Under the power output of the electric motor, it can achieve a 360-degree rotation function (during operation, it only needs to rotate a maximum of 180 degrees to complete the clamping and flipping functions).

[0018] 3. Semi-circular support frame: The semi-circular support frame is welded from 10mm thick steel plate and is welded to the overall bottom surface in two locations (one at each end), symmetrically distributed. A rotating wheel is installed at the circular hole at the top of the support frame, which supports the rotation of the entire device and assists in the flipping of the aluminum profile. A motor bracket is located at the bottom of the support frame. This motor bracket is twice the size of the motor bracket on the rotating wheel because it needs to support two motors working simultaneously, providing power for the rotation of the rotating wheel.

[0019] There are four rotating wheels, totaling two symmetrically distributed. The core section is welded from 10mm thick steel plate, mounted on one side via bearings and a semi-circular support. Four holes on the edge connect the pressure arm rotating rod and the rotating rod gear head via bearings. Four motor brackets are welded to the outside, each mounting a motor that drives the rotating rod gear head via gears. A ring of gears is distributed around the outer edge of the rotating wheels, working in conjunction with the two motor gears at the bottom to achieve overall rotation and complete the flipping of the aluminum profile.

[0020] 5. Rotary Gear Heads: There are a total of eight rotary gear heads (four pairs, symmetrically distributed in pairs), constructed from a single piece of steel and welded together with the pressure arm and rotating rod. The outer edge of each rotary gear head has a ring of gears, which, driven by the gears on the motor, can rotate 360 ​​degrees (in actual operation, a maximum rotation of 180 degrees is sufficient to complete the task). During operation, the top two pairs and the bottom two pairs of rotary gear heads work in opposite directions (the bottom two pairs simultaneously rotate 180 degrees inwards and maintain balance to support the aluminum profile with the mechanical pressure arm; the top two pairs simultaneously rotate 180 degrees outwards to make room for the grinder; after grinding, the top two pairs of mechanical pressure arms simultaneously rotate 180 degrees inwards to press the aluminum profile, then the wheel rotates another 180 degrees, and the top two pairs of mechanical pressure arms simultaneously rotate 180 degrees outwards to complete the grinding of the other side).

[0021] Six motors (2.2KW each) power the rotating system. Each mechanical pressure arm is equipped with two motors, totaling eight motors across four sets of mechanical pressure arms. The bottom of the rotating wheel has two motors on one side and four motors on both sides. The motors are mounted on motor brackets and secured together with screws and nuts. This device requires a total of 12 motors.

[0022] 7. Motor bracket: The motor bracket is made of 20mm thick steel plate and welded to the outside of the rotor. A flat steel plate serves as the main support surface for the motor. Three sets (four sets for the bottom motor bracket on the rotor) of right-angled triangular reinforcing steel plates are welded to the bottom to ensure sufficient support after the motor is placed. A total of eight sets of motor brackets are configured on the rotor (symmetrically distributed in pairs). Two sets of motor brackets are symmetrically distributed at the bottom of the semi-circular support frame. These brackets have four sets of right-angled triangular reinforcing steel plates at their bottom to provide support for the two motors placed on them.

[0023] 8. The bottom track is made of 20mm thick steel plate and welded to the overall bottom surface. The bottom track is welded into a cuboid structure, with a set of 20mm thick rectangular structural steel plates welded to each of the two long sides (each of these steel plates protrudes 50mm from the top surface of the bottom cuboid). The top of the track holds the grinding machine stand, which moves back and forth via electric wheels, directly driving the grinding machine to perform forward and backward grinding operations.

[0024] Nine electric wheels: The electric wheels are 500-watt mechanical electric wheels, totaling eight (four in a group, two groups symmetrically distributed). They are installed at the bottom of the grinder stand, with their bottom directly contacting the top of the bottom track. The rotation of the electric wheels can drive the grinder stand to move forward or backward along the bottom track. When the electric wheels drive the grinder stand to the two short side tracks, it can automatically stop moving.

[0025] 10. The overall base is made of 10mm thick steel plate and has a cuboid structure. Semi-circular uprights are welded to the top two sides of its short sides, and bottom tracks are welded to the two sides of its long sides. The overall base provides support for the entire system and connects the important main structures together.

[0026] 11. Pressure Arm Reinforcing Bars: These reinforcing bars are made of 80mm diameter × 10mm thick steel tubing and are installed at the front circular hole of the mechanical pressure arm. They are welded to the circular hole of the mechanical pressure arm. There are a total of four pressure arm reinforcing bars, each installed on one of the four mechanical pressure arms. This ensures that each mechanical pressure arm can work on the same horizontal plane, providing a strong connection force for clamping and rotating the aluminum profile.

[0027] 12. Hydraulic System: The hydraulic system is welded to the grinding machine's upright frame. Its bottom hydraulic rod is connected to the grinding machine via a round hole and pin. The hydraulic system, controlled by a controller, allows for upward and downward adjustment of the grinding machine's position. When the grinding machine is not in use, the hydraulic system adjusts the hydraulic rod to its highest position. During operation, the grinding machine adjusts its downward movement distance according to the thickness of the aluminum profile being ground.

[0028] 13. The grinding machine stand is welded from 80mm square tubing (5mm thick). It has an inverted U-shaped structure with double rows at both ends of the bottom and a single row at the top, reinforced with welded square tubing. Electric wheels are installed at the bottom, allowing for automatic back-and-forth movement along a track. A hydraulic system is installed at the top, enabling automatic grinding when used with an electric grinding machine.

[0029] 14. Electric Grinding Machine: This electric grinding machine has a power of 1 kilowatt and uses a motor to drive the external grinding brush. It is mounted at the end of a hydraulic rod and connected via a round pin. This electric grinding machine replaces manual labor, enabling continuous and uninterrupted output and improving grinding efficiency.
