Description

Technical Field

[0001] This application relates to the field of bending machine technology, and more specifically, to a bending device for machining. Background Technology

[0002] In the field of sheet metal processing, edge bending of metal sheets is a common process. Traditional bending machines typically require manual loading of metal sheets. During loading, operators must continuously hold the sheet and move it upwards while bending, which presents some inconveniences and safety hazards. Hand injuries may occur due to operational errors, and the labor intensity is increased. Furthermore, the sheet is prone to positional shifts during bending, resulting in skewed bending lines, which affects bending accuracy and product quality, making it difficult to meet the needs of efficient production. In view of this, we propose a bending device for machining. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a bending device for machining, which solves the technical problems in the background art mentioned above. The device enables rapid feeding and positioning of metal sheets, avoids the problem of manual handling of metal sheets during bending, improves the safety and convenience of operation, reduces labor intensity, and utilizes a stop bar to fit the metal sheet. With the help of the scale lines on the concave placement plate, it is convenient for operators to observe and adjust the position of the metal sheet, effectively avoids the bending lines being skewed, ensures bending accuracy, improves product quality, and adapts to different sizes and bending requirements.

[0005] 2. Technical Solution

[0006] This application provides a bending device for machining, comprising: a bending machine body, a pressure plate being drivenly connected to the transmission table of the bending machine body, a lower die base being fixedly installed on the bending machine body corresponding to the bottom of the pressure plate, a concave placement plate being rotatably installed on the bending machine body, and two pneumatic struts being hinged between the bending machine body and the concave placement plate, and a clamping mechanism and an adjusting mechanism being installed on the concave placement plate for positioning and installing metal plates;

[0007] The clamping mechanism includes a small motor, which is fixedly mounted on the bottom surface of the concave placement plate. The output shaft is fixedly equipped with a second gear, which meshes with a Z-shaped rack. The Z-shaped rack is slidably connected to the concave placement plate, and each end is meshed with a first gear. The first gear is fixedly equipped with a rotating rod, which is rotatably connected to two hinge seats. The hinge seats are fixedly connected to the concave placement plate. The rotating rod is fixedly connected to an arc-shaped hinge frame, which is rotatably hinged to a clamping plate.

[0008] The adjusting mechanism includes a threaded rod and a stop bar. The threaded rod is threadedly connected to a concave placement plate, and its end is rotatably connected to the stop bar. The metal plate is fitted and connected to the stop bar.

[0009] By adopting the above technical solution, the pressure plate is moved up and down by the built-in transmission mechanism of the transmission table in the main body of the bending machine. This allows for bending of the metal sheet in conjunction with the lower die. During the bending process, the metal sheet will curl upwards along the crease. A concave placement plate is rotatably mounted on the main body of the bending machine to hold the metal sheet. Two pneumatic struts are hinged between the main body of the bending machine and the concave placement plate. These struts provide stable support, and during the bending process, the concave placement plate rotates as the pneumatic struts extend and retract. The position and angle of the metal sheet are adjusted by a clamping mechanism and an adjusting mechanism installed on the concave placement plate. The clamping mechanism is used to firmly hold the metal sheet and prevent it from shifting during bending. In the adjusting mechanism, the position of the stop bar can be adjusted by rotating the threaded rod, thereby precisely adjusting the position of the metal sheet and ensuring the accuracy and precision of bending. Through the coordinated action of these mechanisms, the positioning and installation of the metal sheet is achieved, meeting the requirements of the bending process. The bending and lifting process of the metal sheet does not require manual operation by the operator, improving safety.

[0010] Optionally, the concave placement plate is fixedly provided with two connecting frames near the lower die base. The ends of the connecting frames are rotatably provided with rotating shafts, and the rotating shafts are rotatably connected to support seats. The support seats are fixedly provided on the body of the bending machine.

[0011] By adopting the above technical solution, the concave placement plate is rotatably hinged to the rotating shaft through the connecting frame, so that the concave placement plate can rotate with the rotating shaft as the support point, ensuring the stability and accuracy of the concave placement plate during the movement, preventing excessive shaking or displacement, and ensuring the smooth progress of the bending operation.

[0012] Optionally, the lower mold base is provided with an angular groove, and the axis of the rotating shaft is located on the extension line of the bottom corner of the angular groove of the lower mold base.

[0013] By adopting the above technical solution, the shape of the angular groove matches the requirements of the bending operation, which can better accommodate and support the deformation of the metal sheet during the bending process. Moreover, the axis of rotation is set on the extension line of the bottom corner of the angular groove of the lower die base, so that when the concave placement plate moves, it can more accurately guide the metal sheet into the appropriate bending position, further improving the bending accuracy and ensuring the consistency and high quality of the bending effect.

[0014] Optionally, the concave placement plate has multiple elliptical grooves on its surface, which are distributed in a rectangular array, and scale lines are provided on the upper surface of the concave placement plate and at both ends.

[0015] By adopting the above technical solution, the elliptical groove design facilitates the operator's initial positioning and fixation of the metal sheet, preventing the sheet from sliding randomly during placement. The concave placement plate, with its scale lines, provides the operator with an intuitive length reference, facilitating precise adjustment of the metal sheet's position, ensuring the accuracy and repeatability of each bending operation, and improving production efficiency and product quality.

[0016] Optionally, the concave placement plate has a guide groove that matches the Z-shaped rack, and the small motor is fixedly connected to a mounting base, which is fixedly disposed on the bottom surface of the concave placement plate.

[0017] By adopting the above technical solution, the small motor is fixed on the bottom surface of the concave placement plate through the mounting base, so that the small motor can stably drive the second gear to rotate, thereby ensuring the normal operation of the clamping mechanism and realizing reliable clamping of metal plates.

[0018] Optionally, both ends of the pneumatic strut are rotatably hinged to a rotating seat, and the two rotating seats are respectively fixedly installed on the bending machine body and the concave placement plate.

[0019] By adopting the above technical solution, the pneumatic strut can effectively connect the bending machine body and the concave placement plate, providing stable power support for the lifting and rotation of the concave placement plate, ensuring that the concave placement plate can move according to the predetermined motion trajectory during the bending process, and ensuring the smooth progress of the bending operation and the stability of the bending quality.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figures 1 to 5 This application provides a bending device for machining, comprising: a bending machine body 1, a pressure plate 2 connected to the transmission table of the bending machine body 1, a lower die base 3 fixedly installed on the bending machine body 1 corresponding to the bottom of the pressure plate 2, a concave placement plate 4 rotatably installed on the bending machine body 1, and two pneumatic struts 8 hinged between the bending machine body 1 and the concave placement plate 4, and a clamping mechanism 6 and an adjusting mechanism 7 installed on the concave placement plate 4 for positioning and installing metal plates 5;

[0033] The clamping mechanism 6 includes a small motor 68, which is fixedly mounted on the bottom surface of the concave placement plate 4. The output shaft is fixedly mounted with a second gear 67. The second gear 67 is meshed with a Z-shaped rack 66. The Z-shaped rack 66 is slidably connected to the concave placement plate 4, and each end is meshed with a first gear 65. The first gear 65 is fixedly mounted with a rotating rod 64. The rotating rod 64 is rotatably connected to two hinge seats 63. The hinge seats 63 are fixedly connected to the concave placement plate 4. The rotating rod 64 is fixedly connected to an arc-shaped hinge frame 62. The arc-shaped hinge frame 62 is rotatably hinged to a clamping plate 61.

[0034] The adjustment mechanism 7 includes a threaded rod 71 and a stop bar 72. The threaded rod 71 is threadedly connected to the concave placement plate 4, and its end is rotatably connected to the stop bar 72. The metal plate 5 is fitted and connected to the stop bar 72. The pressure plate 2 is moved up and down by the transmission mechanism built into the transmission table of the bending machine body 1, which can cooperate with the lower die base 3 to perform bending operations on the metal plate 5. During the bending operation, the metal plate 5 will curl upward along the crease. The concave placement plate 4 is rotatably mounted on the bending machine body 1. The concave placement plate 4 is used to place the metal plate 5. Two pneumatic struts 8 are hinged between the bending machine body 1 and the concave placement plate 4. The pneumatic struts 8 can provide stable support force during bending. During the process, the concave placement plate 4 can rotate with the extension and retraction of the pneumatic strut 8, thereby adjusting the position and angle of the metal plate 5. The concave placement plate 4 is equipped with a clamping mechanism 6 and an adjusting mechanism 7. The clamping mechanism 6 is used to firmly clamp the metal plate 5 to prevent displacement of the metal plate 5 during bending. In the adjusting mechanism 7, the position of the stop bar 72 can be adjusted by rotating the threaded rod 71, thereby precisely adjusting the position of the metal plate 5 to ensure the accuracy and precision of bending. Through the synergistic action of these mechanisms, the positioning and installation of the metal plate 5 is achieved, meeting the requirements of the bending process. The bending and lifting process of the metal plate 5 does not require manual operation by the operator, improving safety.

[0035] Reference Figure 2 and Figure 4 Two connecting frames 41 are fixedly provided near the lower die base 3 on the concave placement plate 4. The end of the connecting frame 41 is rotatably provided with a rotating shaft 411. The rotating shaft 411 is rotatably connected to a support base 42. The support base 42 is fixedly provided on the body 1 of the bending machine. The concave placement plate 4 is rotatably hinged to the rotating shaft 411 through the connecting frame 41, so that the concave placement plate 4 can rotate with the rotating shaft 411 as the support point, ensuring the stability and accuracy of the concave placement plate 4 during the movement, preventing it from shaking or displacing excessively, and ensuring the smooth progress of the bending operation.

[0036] Reference Figure 1 and Figure 2The lower die base 3 is provided with an angular groove, and the axis of the rotating shaft 411 is located on the extension line of the bottom corner of the angular groove of the lower die base 3. The shape of the angular groove matches the requirements of the bending operation, which can better accommodate and support the deformation of the metal plate 5 during the bending process. Furthermore, the axis of the rotating shaft 411 is located on the extension line of the bottom corner of the angular groove of the lower die base 3, which allows the concave placement plate 4 to more accurately guide the metal plate 5 into the appropriate bending position when it moves, thereby further improving the bending accuracy and ensuring the consistency and high quality of the bending effect.

[0037] Reference Figure 1 and Figure 2 The concave placement plate 4 has multiple elliptical grooves 43 arranged in a rectangular array on its surface. Scale lines 44 are provided on the upper surface of the concave placement plate 4 at both ends. The design of the elliptical grooves 43 facilitates the operator's initial positioning and fixing of the metal plate 5, preventing the plate from sliding freely during placement. The scale lines 44 on the concave placement plate 4 provide the operator with an intuitive length reference, facilitating precise adjustment of the position of the metal plate 5, ensuring the accuracy and repeatability of each bending operation, and improving production efficiency and product quality.

[0038] Reference Figure 4 and Figure 5 The concave placement plate 4 has a guide groove 45 that matches the Z-shaped rack 66. The small motor 68 is fixedly connected to the mounting base 69, which is fixedly located on the bottom surface of the concave placement plate 4. The small motor 68 is fixedly located on the bottom surface of the concave placement plate 4 through the mounting base 69, so that the small motor 68 can stably drive the second gear 67 to rotate, thereby ensuring the normal operation of the clamping mechanism 6 and realizing reliable clamping of the metal plate 5.

[0039] Reference Figure 4 and Figure 5 Both ends of the pneumatic strut 8 are rotatably hinged with a rotating seat 81. The two rotating seats 81 are fixedly installed on the bending machine body 1 and the concave placement plate 4, respectively. The pneumatic strut 8 can effectively connect the bending machine body 1 and the concave placement plate 4, providing stable power support for the lifting and rotation of the concave placement plate 4, ensuring that the concave placement plate 4 can move according to the predetermined motion trajectory during the bending process, and ensuring the smooth progress of the bending operation and the stability of the bending quality.

[0040] Working principle: In use, the metal plate 5 is placed on the concave placement plate 4, so that the end face of the concave placement plate 4 away from the bending machine body 1 is in contact with the stop bar 72. The position of the metal plate 5 is adjusted by rotating the threaded rod 71 to achieve a suitable bending position. The small motor 68 is started, and the output shaft of the small motor 68 drives the second gear 67 to rotate. The second gear 67 meshes with the Z-shaped rack 66, and the Z-shaped rack 66 slides along the concave placement plate 4, causing the first gear 65, which is meshed at both ends, to rotate in the opposite direction. The first gear 65 drives the corresponding arc-shaped hinge frame 62 to rotate through the rotating rod 64, so that the arc-shaped hinge frame 62 drives the clamping plate 61 to rotate, and the two clamping plates 61 clamp the metal plate 5. When the transmission platen 2 of the main body 1 of the bending machine moves down, the platen 2 presses the metal plate 5 into the angular groove of the lower die base 3. As the metal plate 5 is bent, the end of the metal plate 5 near the stop bar 72 will lift up. The concave placement plate 4 will overcome the pneumatic support rod 8 and rotate along the rotating shaft 411 with the metal plate 5. When the platen 2 rises, under the reset action of the two pneumatic support rods 8, the concave placement plate 4 drives the metal plate 5 to reset to the initial horizontal state, which facilitates the unloading operation. This solves the problem that the operator must hold the metal plate 5 by hand during the bending process of the traditional metal plate 5, and avoids the problem of the bending line being skewed when the metal plate 5 is bent, thus improving the bending processing accuracy.
