Description

Technical Field

[0001] This utility model relates to the field of bending machines, specifically a bending machine with a positioning mechanism. Background Technology

[0002] Bending machines are indispensable equipment in modern industrial production. Their main function is to precisely bend metal sheets into various angles and shapes according to requirements. This not only improves production efficiency but also greatly enhances product quality. The emergence of bending machines marks an important step for the manufacturing industry towards automation and precision. In the development of society and the economy, bending machines play a key role in helping industrial upgrading and promoting the modernization of industry, and their status cannot be ignored.

[0003] However, when bending thin plates, traditional bending machines require operators to manually place the plates accurately on the stamping table. The plates are subjected to pressure during bending, and if the plates are misaligned, the plates will be wasted. This operation method relies heavily on the operator's experience and skills, and may also lead to fatigue and potential personal safety hazards. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a bending machine with a positioning mechanism, which can stably clamp the plate that needs to be bent, and transport and bend the plate through a relatively stable conveying method, thereby reducing the probability of the plate shifting position during bending.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bending machine with a positioning mechanism, comprising a worktable, a mounting frame, and a sliding seat. The mounting frame is fixed to one side of the top of the worktable, and a sliding seat is provided above the other side of the worktable. Three sets of adjusting cylinders are fixed to the top of the sliding seat, and threaded adjusting rods are threadedly connected to the inside of the adjusting cylinders. A connecting piece is fixed to the top of the threaded adjusting rod, and a handle is fixed to the top of the connecting piece. A lower pressure pad is rotatably connected to the bottom of the threaded adjusting rod. A first slider is fixed to the bottom of the sliding seat, and second sliders are fixed to both sides of the bottom of the sliding seat.

[0006] By adopting the above technical solution, the mounting bracket is used to provide stable installation and load-bearing function for the internal components, the sliding seat is used to provide placement space for the plate schematic, the adjusting cylinder is threadedly connected to the threaded adjusting rod, so that when the threaded adjusting rod rotates, the vertical position can be adjusted inside the adjusting cylinder, the connecting piece is used to form an integrated structure with the handle and the threaded adjusting rod, the lower pressure pad is used to press down on the plate schematic below, and the first slider and two sets of second sliders provide stable movement function for the sliding seat by engaging and sliding with the worktable.

[0007] Furthermore, a drive cylinder is installed on the inner top of the mounting bracket, and two sets of limiting posts are fixed inside the mounting bracket on both sides of the drive cylinder.

[0008] By adopting the above technical solution, a drive cylinder is installed on the inner top of the mounting frame, enabling the bending machine to achieve automated and efficient bending operations. The two sets of limiting posts fixed inside the mounting frame and on both sides of the drive cylinder play a key guiding and limiting role.

[0009] Furthermore, a lower pressure plate is installed at the output end of the drive cylinder and is slidably connected to two sets of lower pressure plates. The bottom of the lower pressure plate is tightened with a bent head by bolts.

[0010] By adopting the above technical solution, and by installing a lower pressure plate at the output end of the drive cylinder and slidingly connecting it with two sets of limit posts, the bending machine achieves efficient and precise bending of the sheet metal. The bottom of the lower pressure plate is tightened with bolts to form a bending head. This connection method is both strong and easy to maintain and replace.

[0011] Furthermore, a bent seat is fixed to one side of the top of the workbench by bolts, and a groove structure is provided on the other side of the top of the workbench for the first slider and two sets of second sliders to slide. Several sets of support feet are fixed to the bottom of the workbench.

[0012] By adopting the above technical solution, the bending seat is fixedly fastened to one side of the top of the workbench with bolts, ensuring the stability and accuracy of the bending operation. The bending seat is an important support component in the bending process of the sheet metal. Its position is fixed and firm, and it can withstand various forces in the bending process, thereby ensuring the bending quality and accuracy. The groove structure opened on the other side of the top of the workbench provides a precise sliding track for the first slider and the two sets of second sliders.

[0013] Furthermore, a drive motor is installed on one side of the worktable, and a lead screw is fixedly connected to the output end of the drive motor, and the lead screw is threadedly connected to the first slider.

[0014] By adopting the above technical solution, by installing a drive motor on one side of the worktable and fixing its output end to the lead screw, and by the threaded connection design between the lead screw and the first slider, the smoothness and accuracy of the movement are enhanced.

[0015] Furthermore, the sliding seat has a plate schematic body inside, and the plate schematic body abuts against three sets of lower pressure pads, and the three sets of lower pressure pads are made of soft rubber material.

[0016] By adopting the above technical solution, and by setting a plate schematic body inside the sliding seat and pressing it against three sets of lower pressure pads, the bending machine achieves stable clamping of the plate schematic body.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model is provided with a sliding seat, adjusting cylinder, threaded adjusting rod and lower pressure pad. The top of the sliding seat is fixed with three sets of adjusting cylinders, and the inside of the adjusting cylinder is threadedly connected to the threaded adjusting rod. When the handle is turned, the handle will drive the threaded adjusting rod to rotate through the connecting piece. The threaded adjusting rod can be adjusted up and down by being threadedly connected to the adjusting cylinder, thereby driving the lower pressure pad connected to the bottom of the threaded adjusting rod to move synchronously, so that the lower pressure pad can clamp the plate body inside the sliding seat below.

[0019] 2. In this utility model, a first slider is fixed to the bottom of the sliding seat, and a second slider is fixed to both sides of the bottom of the sliding seat. The first slider and the two sets of second sliders are respectively engaged and slid with the worktable. At the same time, the first slider is threadedly connected to the lead screw inside the worktable. Thus, when the drive motor drives the lead screw to rotate, the lead screw is threadedly connected to the first slider, and the first slider engages and slides with the worktable, thereby allowing the first slider to drive the sliding seat to move above the worktable. The two sets of second sliders on both sides of the bottom of the sliding seat provide better stable movement of the sliding seat. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] In this embodiment:

[0027] A bending machine with a positioning mechanism, such as Figures 1-4 As shown, the system includes a workbench 1, a mounting bracket 3, and a sliding seat 11. The mounting bracket 3 is fixed to one side of the top of the workbench 1, and the sliding seat 11 is provided on the other side of the workbench 1. Three sets of adjusting cylinders 14 are fixed to the top of the sliding seat 11, and threaded adjusting rods 15 are threadedly connected inside the adjusting cylinders 14. A connecting piece 16 is fixed to the top of the threaded adjusting rod 15, and a handle 17 is fixed to the top of the connecting piece 16. A lower pressure pad 18 is rotatably connected to the bottom of the threaded adjusting rod 15. A first slider 12 is fixed to the bottom of the sliding seat 11, and second sliders 13 are fixed to both sides of the bottom of the sliding seat 11.

[0028] In this design, a sliding seat 11 is installed on the workbench 1. By using a threaded connection adjustment method, when the handle 17 is turned, the handle 17 drives the threaded adjustment rod 15 to rotate through the connecting piece 16. This allows the threaded adjustment rod 15 to be adjusted up and down inside the adjustment cylinder 14 during rotation, thereby precisely adjusting the up and down position of the lower pressure pad 18. This adapts to the processing requirements of sheet metal 19 with different thicknesses and sizes. The first slider 12 fixed at the bottom of the sliding seat 11 and the second sliders 13 on both sides form a sliding fit with the workbench 1, ensuring the stability and smoothness of the sliding seat 11 during movement.

[0029] See Figure 1 and Figure 2 A drive cylinder 5 is installed on the top inner side of the mounting bracket 3, and two sets of limit posts 6 are fixed inside the mounting bracket 3 and on both sides of the drive cylinder 5.

[0030] Among them, the drive cylinder 5 has powerful driving force and precise control capability, which can drive the lower pressure plate 7 and the bending head 8 to perform fast and accurate bending actions, thereby greatly improving production efficiency and ensuring the stability and consistency of bending quality. The limit post 6 can ensure that the lower pressure plate 7 maintains a stable trajectory during the up and down movement, preventing processing errors caused by deviation or shaking.

[0031] See Figure 2 The output end of the drive cylinder 5 is equipped with a lower pressure plate 7 and is slidably connected to two sets of lower pressure plates 7. The bottom of the lower pressure plate 7 is fastened with a bent head 8 by bolts.

[0032] Driven by the driving cylinder 5, the lower pressure plate 7 can move stably up and down along the limit post 6, ensuring the accuracy and repeatability of the bending action. By tightening the bolts, the connection between the bending head 8 and the lower pressure plate 7 can be ensured to be stable and reliable, avoiding processing errors caused by loosening or displacement. In addition, this connection method also makes it easy to replace different models of bending heads 8 according to actual conditions to adapt to different bending requirements, further improving the flexibility and versatility of the equipment.

[0033] See Figure 1 , Figure 2 and Figure 4 The top side of the workbench 1 is fixed with a bent seat 4 by bolts, and the other side of the top of the workbench 1 is provided with a groove structure for the first slider 12 and two sets of second sliders 13 to slide. The bottom of the workbench 1 is fixed with several sets of support feet 2.

[0034] The bolt fastening method is not only easy to install, but also provides sufficient connection strength to prevent the bending seat 4 from shifting or loosening during operation. The groove structure opened on the other side of the top of the workbench 1 allows the sliding seat 11 to move smoothly and accurately along the groove structure, ensuring the precise positioning of the plate body 19 during the bending process.

[0035] See Figure 1 , Figure 3 and Figure 4 A drive motor 9 is installed on one side of the workbench 1, and a lead screw 10 is fixedly connected to the output end of the drive motor 9, and the lead screw 10 is threadedly connected to the first slider 12.

[0036] The drive motor 9 can precisely control the rotation of the lead screw 10, thereby driving the first slider 12, which is threadedly connected to it, to slide along the groove structure.

[0037] See Figure 3 The sliding seat 11 has a plate body 19 inside, and the plate body 19 abuts against three sets of lower pressure pads 18, and the three sets of lower pressure pads 18 are made of soft rubber material.

[0038] By setting the plate schematic body 19 inside the sliding seat 11 and making it abut against the three sets of lower pressure pads 18, the position of the plate schematic body 19 is fixed during the bending process, preventing the plate schematic body 19 from sliding or shifting, thereby improving the bending accuracy and quality. The softness and wear resistance of the soft rubber material also help to extend the service life of the lower pressure pads 18, reduce the replacement frequency, and thus reduce maintenance costs.

[0039] The implementation principle of this utility model is as follows: First, the workbench 1 is stably placed in the designated position by several sets of supporting feet 2 at the bottom. Then, the plate body 19 to be bent is placed inside the sliding seat 11. Subsequently, the three sets of handles 17 on the top of the sliding seat 11 are rotated, so that the handles 17 drive the threaded adjusting rod 15 to rotate through the connecting piece 16. The threaded adjusting rod 15 is threadedly connected to the adjusting cylinder 14, so that its up and down position can be adjusted. This drives the lower pressure pad 18 connected to the bottom of the threaded adjusting rod 15 to move synchronously, so that the lower pressure pad 18 clamps the plate body 19 inside the sliding seat 11. Then, the drive motor 9 is turned on through the control center, so that it drives the lead screw 10 to rotate. The lead screw 10 is threadedly connected to the first slider 12, and the first slider 12 is engaged with the workbench 1. The slide allows the first slider 12 to move the sliding seat 11 above the worktable 1. The two sets of second sliders 13 on both sides of the bottom of the sliding seat 11 provide good stability for the sliding seat 11. Then, the drive cylinder 5 on the top of the inner side of the mounting bracket 3 is opened through the control center, which drives the lower pressure plate 7 at the output end to move downward. The bending head 8 at the bottom of the lower pressure plate 7 cooperates with the bending seat 4 inside one side of the worktable 1 to bend the sheet metal 19. The bending head 8 and the bending seat 4 are fastened to the lower pressure plate 7 and the worktable 1 respectively by existing bolts. Different models can be replaced according to the actual situation. Finally, after the sheet metal 19 has been bent, the operator can easily remove the sheet metal 19 from the sliding seat 11 by performing the reverse steps of the previous operation.
