Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal processing feeding equipment, specifically an automatic feeding and positioning device for sheet metal parts. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including operations such as shearing, punching, bending, welding, riveting, and forming. These processes transform thin metal sheets into parts or products of various shapes and sizes. The purpose of sheet metal processing is to convert metal sheets into components with specific structures and functions to meet the needs of different industries and products, thereby fulfilling specific product design requirements, such as providing housings for electronic devices or manufacturing body parts for automobiles. Its significance lies in improving production efficiency, reducing costs, ensuring product quality and precision, and promoting the development and technological innovation of related industries.

This invention features a conveyor plate surrounded by skirts that protect the conveyed sheet metal. The uneven surface of the conveyor plate prevents the sheet metal from falling and causing blockages due to displacement during transport. A spring is located below the feeding device, connected to a support plate, and a leather sleeve is fitted over the spring to prevent rust from affecting operation. The spring also effectively eliminates vibrations generated by the conveyor belt during operation.

[0004] Both the above-mentioned technical solutions and traditional sheet metal processing feeding methods lack the function of positioning the sheet metal. The sheet metal is prone to errors due to inaccurate positioning, which in turn affects the quality of subsequent processing, such as cutting deviations and inaccurate bending angles, increasing the defect rate and raising production costs.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] An automatic feeding and positioning device for sheet metal parts includes:

[0031] Main structure; The main structure includes a material box 2 for placing sheet metal sheets and a support 1 for supporting the material box 2. Four sets of supports 1 are symmetrically arranged at the bottom of the material box 2.

[0032] The material bin 2 is used to store sheet metal sheets. Four sets of supports 1 are symmetrically arranged at the bottom of the material bin 2 to provide stable support for the material bin 2. The main structure forms the basic framework of the entire device. The material bin 2 realizes the centralized storage of sheet metal sheets. The supports 1 ensure the stability of the material bin 2 during placement and subsequent operations, and prevent the material loading and positioning operations from being affected by shaking or tilting.

[0033] Please see Figure 1-3 :

[0034] It also includes a feeding mechanism for feeding sheet metal sheets; the feeding mechanism includes a lifting plate 5 disposed in the inner cavity of the material box 2 and a push plate 4 disposed on one side of the upper end of the material box 2, and a discharge port 3 disposed on the other side of the upper end of the material box 2. The push plate 4 is used to push the sheet metal raised by the lifting plate 5 out from the discharge port 3.

[0035] Specifically, a first cylinder 6 is installed at the bottom of the material box 2. The upper end of the piston rod of the first cylinder 6 passes through the material box 2 and is fixedly connected to the bottom center of the lifting plate 5 to drive the lifting plate 5 to lift the sheet metal. A guide rod 7 is arranged around the bottom of the lifting plate 5. The guide rod 7 is slidably inserted into the material box 2, thereby improving the stability of the lifting plate 5. Two sets of second cylinders 8 are symmetrically installed on the outer wall of one side of the upper end of the material box 2. The piston rod end of the second cylinder 8 passes through the material box 2 and is fixedly connected to one side of the push plate 4. The inner cavity of the upper end of the material box 2 is also provided with a hidden groove 20 to hide the push plate 4, thereby avoiding obstruction caused by the lifting of the push plate 4.

[0036] The first cylinder 6 at the bottom of the material box 2 is activated, and the piston rod extends upward, driving the lifting plate 5 fixedly connected to it to rise, thereby lifting the sheet metal placed on the lifting plate 5. The guide rod 7 around the bottom of the lifting plate 5 slides inside the material box 2, playing a guiding and stabilizing role. When the sheet metal rises to a certain height (outlet 3), the two sets of second cylinders 8 symmetrically installed on the outer wall of the upper side of the material box 2 are activated. The piston rod pushes the push plate 4, pushing the sheet metal on the lifting plate 5 out of the outlet 3. After a single loading, the piston rod of the second cylinder 8 resets, retracting the push plate 4 into the hidden groove 20. The hidden groove 20 in the upper inner cavity of the material box 2 can accommodate the push plate 4 during the sheet metal lifting stage, preventing the push plate 4 from obstructing the rise of the sheet metal.

[0037] This design enables automated feeding of sheet metal, improving feeding efficiency and reducing manual intervention. The combination of the first cylinder 6 and the lifting plate 5 efficiently lifts the sheet metal, while the guide rod 7 enhances the stability of the lifting process, preventing the sheet metal from shaking or falling. The second cylinder 8 and the push plate 4 push the sheet metal forward, and the hidden groove 20 design optimizes the feeding process, ensuring its smoothness.

[0038] Please see Figure 1 and Figure 3 :

[0039] It also includes a positioning mechanism for positioning sheet metal sheets; the positioning mechanism includes a guide plate 14 disposed at the discharge port 3 and side edges 15 on both sides of the guide plate 14. The side edges 15 have an inverted L-shaped cross-section, and the two sets of side edges 15 are inclined inward to position and correct the pushed sheet metal. Multiple sets of wheel seats 17 are evenly distributed on the inner side of the side edges 15, and guide wheels 16 are rotatably mounted on one side of the wheel seats 17. A connecting rod 18 is symmetrically arranged on one side of the wheel seat 17. The connecting rod 18 is slidably inserted into the side edge 15, and a limit block is provided at the end of the connecting rod 18. A compression spring 19 is sleeved on the connecting rod 18 between the wheel seat 17 and the inner wall of the side edge 15.

[0040] The sheet metal sheet pushed out from the discharge port 3 enters the positioning area formed by the guide plate 14 and the two side edges 15. Since the two sets of side edges 15 are inverted L-shaped and inclined inward, the sheet metal is constrained by the side edges 15 when passing through, thereby achieving positioning and correction. The guide wheel 16 on the inner wheel seat 17 of the side edge 15 can rotate with the movement of the sheet metal, reducing the friction between the sheet metal and the side edge 15. The wheel seat 17 is connected to the side edge 15 through the connecting rod 18. The compression spring 19 sleeved on the connecting rod 18 provides buffering force. When the sheet metal exerts pressure on the guide wheel 16, the wheel seat 17 can move towards the inner wall of the side edge 15 through the compression spring 19 of the connecting rod 18 to accommodate the passage of sheet metal of different sizes, and reset after the pressure is removed.

[0041] This design effectively solves the problem of inaccurate board positioning in traditional feeding methods. The side panel 15 with its specific structure precisely positions and corrects the board, reducing subsequent processing quality issues caused by positioning errors, such as cutting deviations and inaccurate bending angles. The guide roller 16 and spring structure not only reduce surface wear on the board but also ensure adaptability to different board sizes through positioning and correction, improving processing quality and reducing the defect rate.

[0042] Please see Figure 1 and 4 :

[0043] The lower end of the four sets of supports 1 is provided with a base plate 9, which is arranged in a U-shape. The bottom of the base plate 9 is symmetrically provided with traveling wheels 10. A positioning screw 11 is threadedly installed on the base plate 9 between adjacent supports 1. The lower end of the positioning screw 11 is provided with a rubber block 12 with a trapezoidal cross section, and the upper end of the positioning screw 11 is provided with a knob 13.

[0044] The base plate 9 at the lower end of the four sets of supports 1 and the traveling wheels 10 enable the entire device to be movable. The operator can push the device to the desired position. Once the device reaches the designated position, the positioning screw 11 located between the adjacent supports 1 on the base plate 9 is rotated, causing the rubber block 12 at the lower end of the positioning screw 11 to move downwards and contact the ground. Since the cross-section of the rubber block 12 is trapezoidal, the rubber block 12 will generate a large frictional force when the positioning screw 11 is rotated, thus firmly fixing the device to the ground.

[0045] This design enables flexible movement and positioning of the device, meeting the needs of different working scenarios. When the device position needs to be adjusted, it can be easily moved by the walking wheels 10. After reaching the appropriate position, the device is fixed by the positioning screw 11 and rubber block 12 to prevent the device from shifting due to vibration or external force during operation, thus ensuring the stability of feeding and positioning operations.

[0046] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
