Description

TECHNICAL FIELD

[0001] The utility model relates to sheet metal processing technical field, concretely relates to adjustable sheet metal bending angle positioner. BACKGROUND

[0002] Traditional sheet metal bending operation, when determining the bending angle, often highly depends on manual measurement and experience judgment. Workers usually use measuring tools (such as angle rulers) to make multiple measurements and markings on sheet metal materials, and then control the bending equipment according to these markings. However, this method seriously reduces production efficiency when facing different angle bending requirements. In order to meet the requirements of sheet metal bending angle diversification in production, some enterprises try to use different specifications of molds to realize the bending of specific angles. But this method needs to prepare a large number of molds of different angles in advance.

[0003] Therefore, it has important practical significance to develop an adjustable sheet metal bending angle positioner that can quickly and accurately adjust the bending angle, adapt to different bending requirements, reduce manual measurement errors, and be compatible with automatic production. SUMMARY

[0004] In view of the problems existing in the prior art, the utility model provides an adjustable sheet metal bending angle positioner.

[0005] In order to solve the above technical problems, the utility model solves them through the following technical schemes:

[0006] The adjustable sheet metal bending angle positioner comprises an angle plate arranged obliquely, the end of the angle plate at the lower side is fixed with a sleeve joint ring, further comprises a fixed rod, the sleeve joint ring is sleeved on the fixed rod, and the angle plate can rotate left and right around the fixed rod; support plates are arranged on the front and back sides of the angle plate respectively, and the support plates are provided with fixing devices; after the angle adjustment of the angle plate is completed, the fixing devices are used for fixing the other end of the angle plate on the support plates.

[0007] When performing sheet metal bending operation, first, according to the required sheet metal bending angle, the support plates are moved to the corresponding positions, then the obliquely arranged angle plate is rotated around the sleeve joint ring sleeved on the fixed rod. Since the angle plate can rotate left and right around the fixed rod, the operator can flexibly adjust the angle plate to the expected inclination angle, and this inclination angle corresponds to the bending angle of the sheet metal. Then the fixing devices on the support plates on the front and back sides of the angle plate are used to fix the other end of the angle plate on the support plates. In this way, the angle plate is stably fixed at the set angle, providing an accurate angle reference for sheet metal bending. Compared with the method of relying on manual experience and measuring tools, this structure can set the angle more accurately, reduces the human measurement error, and improves the accuracy of the sheet metal bending angle.

[0008] As preferred, the bottom plate is provided with two mounting plates, and the two ends of the fixing rod are fixed to the side walls of the mounting plates.

[0009] The bottom plate provides a stable support platform for the entire positioner. The two mounting plates provided on the bottom plate serve to fix the fixing rod. The two ends of the fixing rod are firmly fixed to the side walls of the mounting plates, so that the fixing rod can be stably positioned at a set position.

[0010] As preferred, the support plate is movable left and right, a first straight slot is formed in the side wall of the support plate, the fixing device includes a first bolt, a first threaded hole is formed in the end of the side wall of the angle plate away from the fixing rod, one end of the first bolt can pass through the first straight slot and be screwed into the first threaded hole, thereby fixing the angle plate to the support plate.

[0011] The design that the support plate is movable left and right ensures that no matter what angle the angle plate is turned to, the first straight slot can be aligned with the first threaded hole on the angle plate by adjusting the position of the support plate, and then the first bolt is used to fix it. This greatly improves the flexibility of angle adjustment and can adapt to a wider range of angles; the first bolt, one end of which passes through the first straight slot and is screwed into the first threaded hole. As the first bolt is tightened, the angle plate is firmly fixed to the support plate, thereby stabilizing the angle plate at a set bending angle position and providing a reliable angle reference for sheet metal bending. In actual sheet metal bending, the angle plate is fixed as a reference to control the bending equipment to process the sheet metal.

[0012] As preferred, two parallel sliding grooves are formed in the bottom plate, the side walls of the sliding grooves are recessed inward to form limiting grooves, one end of the support plate extends into the sliding grooves, and the left and right side walls of the support plate extend to form extension parts, and the two extension parts extend into the limiting grooves, respectively.

[0013] The two parallel sliding grooves in the bottom plate provide a track for the movement of the support plate. The operator pushes the support plate to move left and right along the direction of the sliding grooves. During the movement, the extension parts slide in the limiting grooves, which not only ensures the stability of the movement of the support plate, but also limits the displacement of the support plate perpendicular to the direction of the sliding grooves, ensuring that the support plate can only move left and right along the direction defined by the sliding grooves. When the angle plate is turned to the appropriate angle, the support plate is moved in this way to align the first straight slot in the side wall of the support plate with the first threaded hole on the angle plate, so that the first bolt can be used to fix the angle plate to the support plate, completing the angle positioning.

[0014] As preferred, a second straight slot is formed in the top wall of the limiting groove, a second threaded hole is formed in the extension part, and a second bolt is included, which can pass through the second straight slot and be screwed into the second threaded hole, thereby fixing the support plate to the limiting groove.

[0015] The top wall of the limiting groove is provided with a second straight slot, and the support plate extension is provided with a second threaded hole corresponding to the second straight slot. The operator can pass the second bolt through the second straight slot and then screw it into the second threaded hole. With the tightening of the second bolt, the support plate is tightly fixed in the limiting groove, thereby further enhancing the stability of the entire positioner structure, ensuring that the angle of the angle plate does not change due to the movement of the support plate during sheet metal bending, and always providing accurate and stable angle reference for sheet metal bending.

[0016] As a preferred, the bottom plate is provided with scales on both sides of the sliding groove, and the side wall of the support plate is fixed with an indicator plate.

[0017] The movement distance of the support plate can be accurately controlled by observing the scale corresponding to the indicator plate. The scale provides a quantitative reference standard, making the position adjustment of the support plate more accurate and quantifiable.

[0018] As a preferred, when the support plate moves to the corresponding position, the angle plate is fixed on the support plate, and the angle of the angle plate is indicated by the scale value indicated by the indicator plate.

[0019] This design allows the operator to quickly and intuitively determine and set the inclination angle of the angle plate, i.e. the bending angle of the sheet metal, without complex calculations or measurements, just by observing the scale corresponding to the indicator plate. This greatly simplifies the angle setting process and reduces the dependence on the operator's professional skills and experience. Even beginners can easily set the desired bending angle accurately.

Detailed Implementation

[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0029] Example

[0030] like Figures 1-6 As shown, the adjustable sheet metal bending angle positioner includes an angle plate 110, a fixed sleeve ring 1101 at the lower end of the angle plate 110, the sleeve ring 1101 being sleeved on the fixed rod 120 and being able to rotate left and right around the fixed rod 120; a support plate 130 is provided on each of the front and rear sides of the angle plate 110, the side wall of the support plate 130 has a first straight groove 1301, and the end of the angle plate 110 away from the fixed rod 120 has a first threaded hole 1102, and the angle plate 110 is fixed on the support plate 130 by passing the first straight groove 1301 and screwing it into the first threaded hole 1102.

[0031] It also includes a base plate 140, on which there are two mounting plates 1401. The fixing rod 120 is fixed at both ends to the side walls of the mounting plates 1401. The base plate 140 has two parallel sliding grooves 1402. The side walls of the sliding grooves 1402 are recessed to form limiting grooves 1403. One end of the support plate 130 extends into the sliding groove 1402, and its left and right side walls extend to form extensions 1303 and respectively extend into the limiting grooves 1403. The top wall of the limiting groove 1403 has a second straight groove 14. 04. The extension 1303 is provided with a second threaded hole 1304. The second bolt 1305 passes through the second straight groove 1404 and is screwed into the second threaded hole 1304 to further fix the support plate 130. The base plate 140 is provided with scales on both sides of the slide groove 1402. The side wall of the support plate 130 is fixed with an indicator plate 1306. When the support plate 130 moves to the corresponding position to fix the angle plate 110, the tilt angle of the angle plate 110 is the scale value indicated by the indicator plate 1306.

[0032] The working principle of the adjustable sheet metal bending angle positioner is as follows:

[0033] Before the sheet metal bending operation, the support plate 130 is moved to the corresponding position according to the required bending angle and the scale. Then the support plate 130 is fixed in the slide groove 1402 with the second bolt 1305.

[0034] Then rotate the angle plate 110 with the connecting point of the sleeve ring 1101 and the fixed rod 120 as the axis, align the first threaded hole 1102 and the first straight slot 1301, and fasten the angle plate 110 with the first bolt 1302. In this way, the angle plate 110 is stabilized at the set angle, providing an accurate angle reference for sheet metal bending. The operator controls the bending equipment based on the angle plate 110 as the reference to bend the sheet metal.

[0035] After the angle of the angle plate 110 is set, the sheet metal is passed through the gap between the sleeve ring 1101 and the bottom plate 140, and the bending point of the sheet metal is set directly below the sleeve ring 1101. At this time, the sheet metal is bent. When the side wall of the sheet metal abuts against the angle plate 110, it indicates that the bending work is completed.

[0036] The above setting eliminates the traditional reliance on manual experience and measuring tools. By cooperating with the fixed rod 120, the support plate 130, and other structures, the angle plate 110 reduces human measurement errors, accurately sets the sheet metal bending angle, improves the accuracy of the bending angle, and ensures product quality.

[0037] The support plate 130 can move left and right, and can adapt to any angle to which the angle plate 110 is rotated. By adjusting the position, the support plate 130 can be accurately fixed with the angle plate 110, meeting the bending needs of various angles and improving the versatility of the equipment. The scale and the indicator plate 1306 are designed to allow the operator to intuitively determine and set the inclination angle of the angle plate 110, without the need for complex calculations or measurements, reducing the requirement for professional skills and experience, improving the operation efficiency, and facilitating the operation of beginners.

[0038] In summary, the above is only a preferred embodiment of the present embodiment. Any changes and modifications made within the scope of the patent application of the present embodiment should be included in the scope of the present patent.
