Description

Technical Field

[0001] The invention relates to the technical field of aluminum bar feeding, in particular to an aluminum bar feeding system. Background Art

[0002] After aluminum bars are cast on the aluminum liquid casting production line, each bar needs to be sawed to ensure uniform internal composition throughout the bar. This ensures that each bar leaving the factory meets the required length while maintaining a smooth sawn surface and a clean, tidy bar body. During the bar cutting process, a loading system is required to load the bars. The existing bar loading system for bar cutting has a loading station in front of the sawing machine to ensure that each bar enters the sawing machine in sequence as needed. This station is responsible for placing the bars on the feed platform and manually pushing the entire system forward. Each bar is pushed from the feed platform into the sawing machine in turn. This work is labor-intensive, and if the operator fails to react in time during the bar pushing process, their fingers are inevitably squeezed. The bar can easily press against the cervical vertebrae as it slides down, posing a significant safety hazard. Summary of the Invention

In addition, the loading process is smooth, eliminating the safety hazards of pushing the rod and the rod body sliding down unsteadily, which may cause the employee's fingers to be squeezed or the cervical spine to be supported, thereby improving the safety of aluminum rod loading. Fifthly, the structure is simple, the operation is convenient, and the manufacturing and operating costs are low. BRIEF DESCRIPTION OF THE DRAWINGS

The aluminum bar conveying system includes a rectangular frame and the conveying direction is from left to right. Specifically, in this embodiment, the aluminum bar conveying system is a chain-driven roller conveying system, including a rectangular frame and a plurality of rollers. The frame includes a left support rod, a front support rod 2-1-1, a right support rod, and a rear support rod 2-1-2 connected in sequence.

The aluminum bars are located on the rollers, and the conveying direction is the same as the direction of the aluminum bar axis.

[0037] The stop rod device is installed at the upper rod mouth. The lower stop rod block 1-5 is processed into a 200mm*50mm rectangular steel plate using a 30mm thick steel plate and the lower serration 1-7 is processed on the top to form a serrated tooth mouth. The upper stop rod block 1-6 is a tooth-engaging steel with an upper serration 1-8 with the same tooth shape as the lower serration 1-7 of the lower stop rod block 1-5 on the bottom. The lower stop rod block 1-5 and the upper stop rod block 1-6 are similar to racks. The upper stop rod block 1-6 is engaged and connected to the lower stop rod block 1-5.

When loosening the stop rod fixing bolt 1-11, the position of the upper stop rod block 1-6 on the lower stop rod block 1-5 can be adjusted to meet the stop rod requirements of aluminum rods of different specifications, thereby improving the flexibility of the device.

[0040] In the rod-up device, the rod-up cylinder fixing seat 1-13 is set on the ground below the front side of the frame and its position corresponds to a reinforcing rod 2-1-3, and the second hinge seat 1-16 is fixed on the top of the corresponding reinforcing rod 2-1-3. The tops of the first hinge seat 1-15 and the second hinge seat 1-16 are both provided with a first horizontal through groove and the two side walls of the first horizontal through groove are both provided with a first pin hole. There are two tilting plates 1-17 and second pin holes are provided at both ends. The two tilting plates 1-17 are parallel to each other and are fixedly connected in the middle by a tilting connecting plate 1-18. The two ends of the two tilting plates 1-17 are respectively clamped on both sides of the first hinge seat 1-15 and the second hinge seat 1-16 and are respectively connected to the first hinge seat 1-15 and the second hinge seat 1-16 through the first rod-up pin shaft 1 -19. The second upper rod pin 1-20 is hinged; a vertical hinge plate 1-22 is fixed to the top of the upper rod cylinder fixing seat 1-13, and a third hinge seat 1-23 is fixed to the bottom of the upper rod cylinder 1-12.

A fourth pin hole is provided on the hinge plate 1-22. The third hinge seat 1-23 is clamped on both sides of the hinge plate 1-22 and is hinged to the hinge plate 1-22 through the third upper rod pin 1-24.

[0041] In this embodiment, three rod loading devices are evenly distributed along the direction of aluminum rod conveying. The rod loading cylinder 1-12 is a 200mm stroke compressed air cylinder. The rod loading cylinder 1-12 moves up and down to drive the tilting plate 1-17 to work and load the rod body. The two tilting plates 1-17 are set vertically and are 50mm*300mm movable plates made of 10mm thick steel plates. 10mm holes are drilled at both ends to form second pin holes. Two corresponding pins are machined from 10mm round steel to form the first rod loading pin 1-19 and the second rod loading pin 1-20. They are used to hinge the first hinge seat 1-15 at the top of the rod loading piston rod 1-14 to the front end of the tilting plate 1-17, and the second hinge seat 1-16 at the top of the reinforcement rod 2-1-3 to the rear end of the tilting plate 1-17. The solenoid valve connected to the upper rod cylinder 1-12 is electrically connected to the controller, and can control the upper rod piston rod 1-14 of the upper rod cylinder 1-12 to rise and fall through the controller to drive the tipping plate 1-17 to rotate. When the upper rod piston rod 1-14 rises, it lifts the aluminum rod at the rear end of the rod receiving device and the front end of the stop rod baffle 1-9, and the tipping plate 1-17 forms a downward slope from front to back, so that a single aluminum rod automatically rolls along the tipping plate 1-17 onto the frame, that is, the feed sawing platform. At the same time, the upper rod piston rod 1-14 rises to the highest position, preventing the lower aluminum rod from entering the tipping plate 1-17. When the upper rod piston rod 1-14 descends, the tipping plate 1-17 connected to one end of the cylinder descends, and the lower aluminum rod automatically rolls to the front of the stop rod baffle 1-9 and above the tipping plate 1-17. The reciprocating operation in sequence can realize the entry of a single aluminum rod into the feed sawing process each time to meet the aluminum rod sawing needs. Among them, the axes of the first upper rod pin 1-19, the second upper rod pin 1-20, and the third upper rod pin 1-24 are parallel to each other, and the bottom of the upper rod cylinder 1-12 is hinged to the hinge plate 1-22 on the top of the upper rod cylinder fixing seat 1-13 through the third hinge seat 1-23, so that when the upper rod piston rod 1-14 rises, the upper rod cylinder 1-12 and the upper rod piston rod 1-14 rotate as a whole toward the rear side along the third upper rod pin 1-24. When the upper rod piston rod 1-14 descends, the upper rod cylinder 1-12 and the upper rod piston rod 1-14 rotate as a whole toward the front side along the third upper rod pin 1-24, so that the upper rod function of the tilting plate 1-17 is smoothly exerted.

[0042] The entire process of the present invention can be achieved by timing the loading of the rods by the controller to achieve fully automatic loading. It can also be achieved by setting a control knob so that a single employee can operate the knob to achieve automatic loading. In this embodiment, the aluminum rod loading system of the present invention includes a control panel, on which a rod loading lifting knob is provided. The rod loading lifting knob is electrically connected to the controller. When the rod loading lifting knob is rotated to one side, a rod loading raising instruction is sent to the controller, and when it is rotated to the other side, a rod loading lowering instruction is sent to the controller. The controller is used to control the solenoid valves of all rod loading cylinders 1-12 to control the extension or retraction of the rod loading piston rods 1-14 of all rod loading cylinders 1-12 according to the instruction of the rod loading lifting knob, thereby controlling the rise or fall of all dumping plates 1-17 near the end of the rod loading cylinder 1-12.

[0043] In the aluminum bar feeding system of the present invention, the structure of the solenoid valve of the rod feeding cylinder 1-12 and its connection relationship with the rod feeding cylinder 1-12 are structures well known in the art, as long as the controller can control the extension or retraction of the rod feeding piston rod 1-14 by controlling the solenoid valve of the rod feeding cylinder 1-12. In this embodiment, the aluminum bar feeding system of the present invention is equipped with a compressed air system, which includes a 7.5KW drive motor and an air pump. The drive motor drives the air pump to compress air and then supply it to the rod feeding cylinder 1-12, with an air pressure of 0.6KPa; the solenoid valve of the rod feeding cylinder 1-12 is a pneumatic solenoid valve, model 4V430C-15.
