Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and more specifically, to an angle precision positioning baffle for bending machines. Background Technology

[0002] Bending machines are the core equipment for achieving precise bending of metal sheets, and angle positioning baffles, as key auxiliary components of bending machines, directly determine the consistency of bending angles and processing accuracy. Whether it is automotive parts, home appliance housings or building hardware, all products have stringent requirements for metal bending angles.

[0003] Existing bending machine positioning baffles are mostly linear track adjustment structures, which can only achieve single-direction positioning. For example, they can only perform positioning operations at a constant angle in the horizontal direction, and cannot adapt to the arc trajectory required by the bending angle, which is prone to errors during the bending process. Some manually adjustable baffles rely on operators to estimate the angle using a protractor, which has a large subjective error and lacks intuitive scale markings, making it difficult to meet the actual positioning accuracy requirements. In view of this, we propose a precision angle positioning baffle for bending machines. Utility Model Content

[0004] The purpose of this invention is to provide a precise angle positioning baffle for bending machines, so as to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The bending machine's angle precision positioning baffle includes a support platform with an arc-shaped hole. Two symmetrical side positioning protrusions are fixedly installed at the center of the top surface of the support platform. A ring-shaped scale line is provided on the upper surface of the support platform. A bottom sliding plate is rotatably connected to the center of the bottom surface of the support platform. A slider is fixedly installed on the end plate of the bottom sliding plate, and the slider is located within and slidably connected to the arc-shaped hole. Two symmetrical positioning baffles are fixedly installed on the top surface of the slider. The raw material is bent onto the side of the positioning baffle for positioning. A front limiting plate is fixedly installed at the front end of the bottom sliding plate, and the front limiting plate is fitted onto the outer surface of the support platform and slidably connected to the support platform. The front limiting plate is fixed to the support platform by fastening bolts.

[0006] Preferably, the cross-section of the arc-shaped hole is greater than half an annular shape, and the scale lines are arranged around the periphery of the two side positioning protrusions; This setting allows for a wider range of angle adjustments, while the scale lines make observation and operation easier.

[0007] Preferably, the positioning baffle is located above the support platform, and the positioning baffle is indicated at the scale line position; This setting makes it easier to determine the angle by comparing the scale lines.

[0008] Preferably, the annular side of the support platform is provided with a plurality of first threaded holes, and the vertical section of the front limiting plate is provided with a second threaded hole, and the fastening bolt is threadedly connected to the second threaded hole and the corresponding first threaded hole. This setting can fix the front limiting plate, thereby limiting the positioning baffle and preventing it from moving easily.

[0009] Preferably, the side positioning protrusions are columnar, and a raw material insertion gap is provided between the two side positioning protrusions; This setting allows the raw material to be inserted normally through the material insertion gap before bending.

[0010] Preferably, a rotating shaft is fixedly installed at the other end of the bottom sliding plate, and a turntable is fixedly installed at the top of the rotating shaft. The rotating shaft is located at the center of the bottom surface of the support platform and is rotatably connected to the support platform. The turntable is embedded in the support platform and is rotatably connected to the support platform. This setting allows the bottom slide to rotate normally, enabling angle adjustment.

[0011] Preferably, a top plate is provided above the support platform, a high-torque motor is installed on the top plate, a connecting rod is installed at the end of the output shaft of the high-torque motor, and a bent protruding column is fixedly installed on the bottom surface of the end plate of the connecting rod; This setup utilizes a high-torque motor to drive the connecting rod and bending protrusion to rotate, enabling the raw material to be bent in the corresponding direction at the side positioning protrusion.

[0012] Preferably, the high-torque motor is located at the upper center of the support platform, and the bent protrusion is located above the arc-shaped hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes an arc-shaped hole on the support platform, a slider at the end of the bottom sliding plate, and an annular scale line on the surface of the support platform. The slider slides along the arc-shaped hole, causing the positioning baffle to adjust in an arc shape. In conjunction with the scale line indicated by the positioning baffle, it achieves precise positioning of the arc trajectory according to bending requirements, replacing the traditional straight track adjustment, avoiding angle deviation, and achieving the effect of improving the positioning accuracy of bending angle and ensuring the consistency of processing of products in the same batch.

[0014] 2. This utility model uses a rotating shaft at the center of the bottom surface of the support platform, a turntable, and a front limiting plate at the front end of the bottom slide plate. Rotating the turntable can drive the bottom slide plate and the positioning baffle to adjust the angle. After adjustment, the second threaded hole of the front limiting plate is fixed to the first threaded hole of the support platform by fastening bolts, which can achieve quick locking and simplify the adjustment operation.

[0015] 3. This utility model uses a side positioning protrusion on the top surface of the support platform and a bending protrusion driven by a high-torque motor on the top plate. The side positioning protrusion provides bending support for the raw material, and the bending protrusion precisely cooperates to complete the bending. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a precision angle positioning baffle for a bending machine, including a support platform 1, on which an arc-shaped hole 10 is provided. The arc-shaped hole 10 provides an arc-shaped sliding trajectory for the slider 22. With the rotation of the bottom slide plate 2, the positioning baffle 23 can adjust the angle along the arc-shaped path. The cross-section of the arc-shaped hole 10 is greater than half an annular shape, which expands the angle adjustment range and meets the bending needs of multiple scenarios such as acute angle, right angle, and obtuse angle, replacing the single adjustment method of the traditional straight track.

[0019] In this embodiment, two symmetrical side positioning protrusions 12 are fixedly installed at the center of the top surface of the support platform 1. The side positioning protrusions 12 are columnar, and a material insertion gap 121 is provided between the two side positioning protrusions 12. The side positioning protrusions 12 provide bending support points for the metal material, making it less likely for the material to deviate during the bending process. At the same time, the material insertion gap 121 between the two protrusions facilitates the precise insertion of the material, ensuring uniform force during bending and improving the bending quality.

[0020] Specifically, the upper surface of the support platform 1 is provided with a ring-shaped scale line 13. A bottom slide plate 2 is rotatably connected to the center of the bottom surface of the support platform 1. A slider 22 is fixedly installed on the end plate of the bottom slide plate 2. The slider 22 is located in the arc-shaped hole 10 and is slidably connected to the arc-shaped hole 10. Two symmetrical positioning baffles 23 are fixedly installed on the top surface of the slider 22. The raw material is bent to the side of the positioning baffle 23 for positioning operation. The positioning baffle 23 is located above the support platform 1. The positioning baffle 23 is indicated at the scale line 13. The operator can intuitively read the angle value corresponding to the positioning baffle 23 without the need to estimate with an external protractor, avoiding subjective errors and improving the accuracy of angle positioning. The bottom slide plate 2 can rotate around the center of the support platform 1, driving the slider 22 at the end and the positioning baffle 23 on the top surface to adjust the angle synchronously. This allows the positioning baffle 23 to accurately adapt to different bending angle requirements, providing precise limits for the bending of the raw material and ensuring that the bending angle meets the processing standards.

[0021] Furthermore, a front limiting plate 24 is fixedly installed at the front end of the bottom slide plate 2. The front limiting plate 24 is sleeved on the outer surface of the support platform 1 and is slidably connected to the support platform 1. The front limiting plate 24 is fixed to the support platform 1 by fastening bolts. When the angle is adjusted, the front limiting plate 24 moves synchronously with the bottom slide plate 2. After the adjustment is completed, it is fixed by fastening bolts, which can lock the position of the bottom slide plate 2 and the positioning baffle 23, avoid positioning displacement caused by vibration during bending, and ensure processing accuracy.

[0022] like Figure 2 As shown, the scale line 13 is set around the periphery of the two side positioning protrusions 12, making it easier to judge the angle by comparing the scale line 13.

[0023] In addition, the support platform 1 has multiple first threaded holes 11 on its annular side and the front limiting plate 24 has a second threaded hole 241 on its vertical section. The fastening bolt is threadedly connected to the second threaded hole 241 and the corresponding first threaded hole 11, which can quickly fix the front limiting plate 24 without disassembling a large number of parts, simplifying the fixing operation, improving the locking efficiency after angle adjustment, and adapting to multi-batch processing scenarios.

[0024] It is worth noting that a rotating shaft 20 is fixedly installed at the other end of the bottom slide plate 2, and a turntable 21 is fixedly installed at the top of the rotating shaft 20. The rotating shaft 20 is located at the center of the bottom surface of the support platform 1 and is rotatably connected to the support platform 1. The turntable 21 is embedded in the support platform 1 and is rotatably connected to the support platform 1, so that the bottom slide plate 2 can rotate normally to achieve angle adjustment.

[0025] like Figure 1 As shown, a top plate 3 is provided above the support platform 1, and a high-torque motor 30 is installed on the top plate 3. A connecting rod 31 is installed at the end of the output shaft of the high-torque motor 30. A bending protrusion 32 is fixedly installed on the bottom surface of the end plate of the connecting rod 31. The high-torque motor 30 provides sufficient power to the connecting rod 31 and the bending protrusion 32, driving them to rotate stably, replacing the traditional manual bending method and reducing the labor intensity of the operator. The connecting rod 31 transmits the motor power to the bending protrusion 32, and the connecting rod 31 enables the bending protrusion 32 to act precisely on the raw material on the support platform 1, ensuring that the bending force can be effectively transmitted to the contact part between the raw material and the side positioning protrusion 12, so as to achieve precise bending of the raw material.

[0026] like Figure 1 As shown, the high-torque motor 30 is located at the center of the support platform 1, and the bending protrusion 32 is located above the arc-shaped hole 10, making it easier for the high-torque motor 30 to drive the connecting rod 31 and the bending protrusion 32 to perform bending operations on the raw material at the side positioning protrusion 12.

[0027] Finally, it should be noted that the high-torque motor 30, the corresponding control system, and the external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0028] When using the angle precision positioning baffle of the bending machine of this utility model, first loosen the fastening bolt between the front limiting plate 24 and the support platform 1, rotate the bottom slide plate 2 around the center of the support platform 1, and the slider 22 at the end of the bottom slide plate 2 slides along the arc hole 10 of the support platform 1, which simultaneously drives the positioning baffle 23 to move. The operator observes the scale line 13 indicated by the positioning baffle 23 to understand the current angle. After aligning with the target angle, pass the fastening bolt through the second threaded hole 241 of the front limiting plate 24 and thread it to the corresponding first threaded hole 11 on the annular side of the support platform 1 for threaded connection and fixation. The metal material is inserted through the material insertion gap 121 between the two side positioning protrusions 12, and the non-bending end of the material is clamped by an external clamp. The high torque motor 30 on the top plate 3 is started, and the motor output shaft drives the connecting rod 31 to rotate. The bending protrusion 32 at the end of the connecting rod 31 rotates accordingly, applying pressure to the material in the horizontal circumferential direction. The material is bent with the side positioning protrusions 12 as support points until it fits against the side of the positioning baffle 23, completing the precise bending.
