[0023] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0024] This application discloses a sheet metal chamfering device.

[0025] A sheet metal chamfering device includes a conveying unit 1, a mounting frame 2, an upper chamfering unit 3, and a lower chamfering unit 4. The conveying unit 1 is used to horizontally clamp and convey the sheet metal 9 along its length. The mounting frame 2 is fixed at a predetermined position. Both the upper chamfering unit 3 and the lower chamfering unit 4 are mounted on the mounting frame 2 and are adjusted by a positioning unit 5, thereby achieving positional adjustment of the two chamfering units in the vertical and horizontal directions.

[0026] Through spatial layout and independent adjustment mechanism, the chamfering of the upper and lower edges is completed simultaneously during the single conveying of the sheet 9. The upper chamfering unit 3 and the lower chamfering unit 4 are independently positioned in space by the positioning unit 5, so that their cutting tools can accurately correspond to the edges to be processed on the upper and lower surfaces of the sheet 9.

[0027] The conveying unit 1 delivers the horizontally clamped sheet metal 9 into the processing area under the mounting frame 2. As the sheet metal 9 passes by, the upper chamfering unit 3 and the lower chamfering unit 4, fixed to the mounting frame 2, are activated simultaneously to chamfer the top and bottom edges of the sheet metal 9, respectively. The entire process is completed continuously in a single straight conveying of the sheet metal 9, without any interruption or flipping.

[0028] The conveying unit 1 consists of a conveyor frame, a conveyor belt, and pressure rollers. The conveyor frame is fixed in a predetermined position, serving as the supporting foundation for the entire unit. The conveyor belt is mounted on the conveyor frame and is powered by a conveyor drive unit to ensure its continuous operation. Multiple pressure rollers are arranged on the conveyor frame along the conveying direction of the sheet material 9. The conveyor drive unit is specifically a conveyor motor.

[0029] Driven by a motor, the conveyor belt provides the main propulsion for the plate 9 to move forward, while multiple pressure rollers distributed along the conveying path apply stable pressure to the plate 9 from above. The purpose is to ensure that the plate 9 remains level and stable during conveying, preventing it from deviating from the preset conveying trajectory due to vibration or warping, thus providing a precise positioning basis for subsequent synchronous chamfering.

[0030] At the start of the operation, the conveyor motor starts, driving the conveyor belt to rotate in a cycle. The sheet metal 9 is placed on the belt and then enters the clamping area composed of multiple pressure rollers. These pressure rollers continuously press against the upper surface of the sheet metal 9, clamping it together with the belt below, allowing it to pass smoothly through the processing area under the mounting frame 2.

[0031] Both the upper chamfer unit 3 and the lower chamfer unit 4 slide in the vertical direction with the mounting bracket 2. The positioning unit 5 consists of two parts: the first positioning element 6 is set on the upper chamfer unit 3, and the second positioning element 7 is independently set on the lower chamfer unit 4.

[0032] By allowing the upper chamfering unit 3 and the lower chamfering unit 4 to slide independently on the mounting bracket 2, and by using the first positioning member 6 and the second positioning member 7, the operator can set the positions of the upper chamfering tool and the lower chamfering tool in the vertical and horizontal directions respectively.

[0033] The first positioning component 6 is jointly composed of a first longitudinal positioning component 61 and a first transverse positioning component 62 carried by the upper chamfering unit 3. The first longitudinal positioning component 61 is adjusted in installation position by the first longitudinal adjusting component 63 to adjust its relative position with the upper chamfering unit 3 in the longitudinal direction, and finally makes the first longitudinal positioning component 61 abut against the top of the plate 9. At the same time, the first longitudinal positioning component 61 and the first transverse positioning component 62, as a whole, are driven by the first transverse adjusting component 64 to adjust their relative position with the mounting bracket 2 in the transverse direction, and make the first transverse positioning component 62 abut against the side of the plate 9.

[0034] By having the first longitudinal positioning member 61 abut against the top surface of the plate 9, the reference height of the tool in the vertical direction is established. By having the first transverse positioning member 62 abut against the side of the plate 9, the reference position of the tool in the horizontal direction is established. Through the combined action of these two directions, the upper chamfering unit 3 is quickly positioned at the machining position corresponding to a specific edge of the plate 9.

[0035] The first longitudinal adjusting member 63 consists of a first longitudinal adjusting frame 631 and a first rotating rod 632. The first longitudinal adjusting frame 631 is fixed to the upper chamfering unit 3. One end of the first rotating rod 632 is fixedly connected to the upper chamfering unit 3. The first longitudinal positioning member 61 is installed at the other end of the first rotating rod 632, and its specific form is a vertically arranged first longitudinal positioning wheel. The longitudinal position of the first longitudinal positioning wheel is adjusted according to the installation position of the first rotating rod 632.

[0036] Under the influence of gravity, the upper chamfering unit 3 can move freely in the vertical direction. This ensures that the first longitudinal positioning wheel mounted on it continuously contacts the top of the plate 9 and forms a rolling engagement with the top of the plate 9 during the conveying process.

[0037] Using the gravity of the upper chamfering unit 3 itself as a constant force source, the upper chamfering unit 3 is driven to move downward until the first longitudinal positioning wheel contacts the top surface of the plate 9.

[0038] During equipment operation, the upper chamfering unit 3 is not forcibly locked in the vertical direction, but is in a suspended state. When the plate 9 is conveyed to its lower position, the first longitudinal positioning wheel naturally falls and presses against the top surface of the plate 9 under the action of gravity.

[0039] The first lateral adjustment component 64 consists of a first lateral adjustment frame 641 and a linear drive component 642. The first lateral adjustment frame 641 is mounted on the upper chamfering unit 3 and can slide with the upper chamfering unit 3 in the horizontal direction. The linear drive component 642 is mounted on the first lateral adjustment frame 641, and the end of its push rod acts on the upper chamfering unit 3. The linear drive component 642 is specifically a first lateral cylinder. The first lateral positioning component 62 is mounted on the first lateral adjustment frame 641 via a sliding frame 67. The first lateral positioning component 62 is a first lateral positioning wheel. A second digital position display 66 is also provided between the first lateral adjustment frame 641 and the sliding frame 67. The operator can understand the relative position of the first lateral positioning component 62 and the first lateral adjustment frame 641 in the horizontal direction through the second digital position display 66, and use this to control and adjust the size of the arc chamfer.

[0040] Using the first transverse cylinder as a power source, a precise horizontal linear thrust or pull force is generated through the extension and retraction of the cylinder push rod. This force acts directly on the upper chamfering unit 3, driving the first transverse adjusting frame 641 and the upper chamfering unit 3 to move laterally, thereby achieving horizontal positioning of the upper chamfering unit 3.

[0041] The upper chamfering unit 3 consists of an upper chamfering base frame 31, an upper chamfering sliding frame 32, and an upper scraper 33. The upper chamfering base frame 31 is mounted on the mounting frame 2 and slides vertically with it. The upper chamfering sliding frame 32 is mounted on the upper chamfering base frame 31 and slides horizontally with it. The upper chamfering sliding frame 32 is fixedly connected to the first horizontal adjustment frame 641, and the upper scraper 33 is mounted on the upper chamfering sliding frame 32. To facilitate workers' visual understanding of the horizontal position of the chamfered arc, the upper chamfering sliding frame 32 and the first horizontal adjustment frame 641 are also equipped with a first digital position display 65. Workers can understand the current horizontal position of the chamfered arc by viewing the numbers displayed on the first digital position display 65.

[0042] The entire upper chamfering unit 3 is vertically floating on the mounting frame 2 via the upper chamfering base 31, driven by gravity, to achieve height self-adaptation. The upper scraper 33 moves horizontally on the upper chamfering base 31 via the upper chamfering sliding frame 32, to achieve precise adjustment of its lateral position.

[0043] When the first transverse cylinder is activated, its push rod pushes or pulls the first transverse adjustment frame 641, which is fixedly connected to the upper chamfering sliding frame 32, thereby driving the upper chamfering sliding frame 32 and the upper scraper 33 on it to move laterally as a whole until the set position is reached. During the processing, the entire upper chamfering unit 3 can be treated as a whole and float freely in the vertical direction with the undulation of the surface of the plate 9.

[0044] The second positioning element 7 is composed of a second longitudinal positioning element and a second transverse positioning element disposed on the lower chamfering unit 4. The relative position of the second longitudinal positioning element with the lower chamfering unit 4 in the longitudinal direction is adjusted by the installation position of the second longitudinal adjusting element, and the positioning element is brought into contact with the bottom of the plate 9.

[0045] Meanwhile, the second longitudinal positioning member and the second transverse positioning member are integrated and driven by the second transverse adjustment member to adjust their relative position with the mounting bracket 2 in the transverse direction, and to make the second transverse positioning member abut against the side of the plate 9.

[0046] In addition, a spring 8 is provided between the lower chamfering unit 4 and the mounting bracket 2. The top end of the spring 8 is connected to the bottom of the lower chamfering unit 4, and the bottom end is connected to the mounting bracket 2. The spring 8 is in a compressed state in its initial state. The pre-compressed spring 8 provides a constant upward thrust to the entire lower chamfering unit 4. This constant elastic force ensures that the second longitudinal positioning member reliably abuts against the bottom surface of the plate 9.

[0047] The lower chamfer unit 4 and the upper chamfer unit 3 have similar overall structures, the second longitudinal positioning member and the first longitudinal unit have similar overall structures, and the second transverse positioning member and the first transverse positioning member 62 have similar structures.

[0048] The implementation principle of the plate chamfering device in this application embodiment is as follows: At the start of operation, the conveyor motor drives the conveyor belt to rotate cyclically, sending the horizontally placed plate 9 into the processing area under the mounting frame 2; multiple pressure rollers distributed on the conveyor path continuously press the upper surface of the plate 9 from above, clamping the plate 9 together with the belt, so that it moves forward in a straight line while maintaining a horizontal and stable state; at the same time, the upper chamfering unit 3 floats vertically along the mounting frame 2 under its own gravity, so that the first longitudinal positioning wheel always abuts against the top surface of the plate 9, establishing the reference height of the upper scraper 33 in the vertical direction; the first transverse cylinder drives the first transverse adjusting frame 641 through the push rod, so that the upper chamfering sliding frame 32 drives the upper scraper 33 to move laterally until the first transverse cylinder moves laterally. The upper chamfering unit 3 is precisely positioned horizontally by the positioning component 62 against the side of the plate 9. Under the constant upward thrust of the pre-compression spring 8, the lower chamfering unit 4 is positioned so that the second longitudinal positioning component is pressed tightly against the bottom surface of the plate 9, establishing the reference height of the lower chamfering unit 4 in the vertical direction. The second transverse adjustment component then drives the second transverse positioning component to press against the side of the plate 9, completing the precise positioning of the lower chamfering unit 4 in the horizontal direction. As the plate 9 is continuously conveyed, the upper chamfering unit 3 and the lower chamfering unit 4, respectively, are in the accurate positions maintained by their positioning units 5, and simultaneously perform continuous chamfering on the top and bottom edges of the plate 9. The entire double chamfering process is completed continuously in one straight conveying of the plate 9 without interruption or flipping.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
