Description

Technical Field

[0001] This utility model relates to the field of locomotive parts processing technology, and in particular to an energy-saving locomotive parts bending device. Background Technology

[0002] Bending is a common and crucial process in the manufacturing and repair of locomotive parts, used to bend metal sheets or profiles into specific shapes to meet assembly or functional requirements. Traditional bending equipment often employs a vertical, single-cylinder-driven, single-station structure. This type of equipment suffers from the following problems in practical use: I. In the traditional bending device, the hydraulic cylinder performs bending operations during the extension phase, while it is in an unloaded state during the return phase. The hydraulic energy consumption during this phase is almost completely wasted, resulting in low overall energy efficiency, which does not meet the current requirements for energy-saving and environmentally friendly production.

[0003] Second, because it only has a single workstation, the equipment needs to wait for unloading and loading operations after completing the bending of a workpiece, resulting in a large amount of idle waiting time, low production efficiency, and difficulty in adapting to the needs of batch and continuous production.

[0004] To address this, we designed an energy-saving locomotive parts bending device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses an energy-saving locomotive parts bending device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An energy-saving locomotive parts bending device includes a workbench, on which a dual-axis hydraulic cylinder is arranged longitudinally in the middle of the workbench surface, and fixed mounting seats are provided at both ends. The two telescopic shafts of the dual-axis hydraulic cylinder are equipped with movable mounting plates. It also includes a first replaceable module and a second replaceable module. The first replaceable mold base and the first replaceable mold head of the first replaceable module are respectively installed on the opposite sides of a set of fixed mounting bases and movable mounting plates in the same direction, so as to drive the first replaceable mold head to move towards the first replaceable mold base to perform bending operations on the first workpiece by a dual-axis hydraulic cylinder. The second replaceable mold base and the second replaceable mold head of the second replaceable module are respectively installed on the opposite sides of another set of fixed mounting bases and movable mounting plates, so as to drive the second replaceable mold head to move towards the second replaceable mold base to perform bending operations on the second workpiece by means of a dual-axis hydraulic cylinder.

[0007] Furthermore, T-shaped grooves are provided at both ends of the upper surface of the workbench, the outer surface of the movable mounting plate, and the inner side of the fixed mounting base for installing different models of replaceable modules.

[0008] Furthermore, the upper surface of the workbench is provided with longitudinally arranged linear slide rails on both sides, and the bottom of the movable mounting plate is slidably connected to the linear slide rails.

[0009] Furthermore, an n-shaped frame is provided above the workbench, and a longitudinal guide post is provided at the top of the inner cavity of the n-shaped frame. The longitudinal guide post slides through the top of the movable mounting plate.

[0010] Furthermore, a pad is provided between the workbench and the n-shaped frame sidewalls facing the same direction for longitudinal positioning of the fixed mounting base.

[0011] Furthermore, protective outer plates are detachably installed in the middle of the horizontal sides of the workbench and the n-shaped frame.

[0012] Furthermore, a hydraulic station is provided at the top of the n-shaped frame to provide power to the dual-axis hydraulic cylinder.

[0013] Furthermore, the working side tail end and lower end of the replaceable mold base are respectively provided with a positioning part and a support part.

[0014] Furthermore, the first replaceable module and the second replaceable module are arranged in an axisymmetric or rotationally symmetric manner.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. A dual-axis hydraulic cylinder is used as the drive source, along with two interchangeable modules. When one telescopic shaft extends for bending operations, the other telescopic shaft retracts simultaneously; conversely, when the first shaft retracts, the other shaft extends simultaneously. This design ensures that the hydraulic cylinder performs effective bending operations in one direction throughout the entire working cycle of extension and retraction, completely solving the problem of traditional single-axis hydraulic cylinders running unloaded during the return stroke and wasting energy, thus greatly improving energy efficiency. 2. It adopts a dual-axis hydraulic cylinder as the drive source and two sets of interchangeable modules, which can realize the loading or unloading of another workpiece while bending one workpiece, significantly reducing the idle time of the equipment, realizing almost continuous production, and greatly improving the output efficiency per unit time. 3. The movement of the modules on both sides is synchronously driven by a dual-axis hydraulic cylinder, and with the help of linear slide rails and longitudinal guide columns, the overall structure is reasonably laid out while ensuring the independence of the two workstations and the accuracy and stability of the operation. This achieves efficient integration of a single power source driving two workstations. 4. The replaceable modules are installed via T-slots, making replacement convenient; and the first and second replaceable modules can be arranged in various ways, such as axisymmetric or rotationally symmetrical, to accommodate different workstation layout requirements according to workshop layout needs.

[0018] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0019] Example 1, in conjunction with Appendix Figure 1-5 An energy-saving locomotive parts bending device includes a workbench 1, on which a longitudinally arranged dual-axis hydraulic cylinder 2 is mounted in the middle of the upper surface. A fixed mounting base 3 is provided at each end of the upper surface of the workbench 1. The two telescopic shafts of the dual-axis hydraulic cylinder 2 are respectively connected to a movable mounting plate 4.

[0020] Specifically, the upper surface of the workbench 1 is provided with T-shaped sliding grooves at both ends, and the fixed mounting base 3 is fixedly installed by multiple matching T-shaped sliders and bolts.

[0021] Furthermore, to ensure that the fixed mounting base 3 remains in a fixed position during operation, a pad 8 is provided between the fixed mounting base 3 and the side wall of the n-shaped frame 7. This pad is used to longitudinally position the fixed mounting base 3 and prevent it from moving outward longitudinally during operation, which would affect the bending quality of the workpiece.

[0022] The first replaceable module 5 includes a first replaceable mold base 51 and a first replaceable mold head 52. The first replaceable mold base 51 is mounted on the fixed mounting base 3 on the right side, and the first replaceable mold head 52 is mounted on the movable mounting plate 4 on the right side, with the two arranged opposite to each other. Similarly, the second replaceable module 6 includes a second replaceable mold base 61 and a second replaceable mold head 62, which are respectively mounted on the fixed mounting base 3 and the movable mounting plate 4 on the left side.

[0023] Specifically, the working side of the first replaceable mold base 51 has a first mold base positioning part 511 at its rear end and a first mold base support part 512 at its lower end. Similarly, the working side of the second replaceable mold base 61 has a second mold base positioning part 611 at its rear end and a second mold base support part 612 at its lower end. These are used for positioning and supporting the workpiece. That is, when placing the first workpiece, the bottom of the first workpiece is first supported by the first mold base support part 512, and then the first workpiece is pushed backward so that its rear end abuts against the first mold base positioning part 511, thus completing the placement of the first workpiece. Similarly, the placement operation of the second workpiece follows the same principle as the placement operation of the first workpiece, and will not be described in detail here.

[0024] Specifically, both the movable mounting plate 4 and the fixed mounting base 3 have T-shaped grooves on their opposite sides. Combined with the longitudinally adjustable feature of the fixed mounting base 3, this bending device can accommodate the installation of different models of replaceable modules. That is, when installing replaceable modules with different longitudinal dimensions, the minimum distance between the movable mounting plate 4 and the fixed mounting base 3 can be increased or decreased by adjusting the longitudinal position of the fixed mounting base 3 to meet the spacing requirements for the replaceable module to be used.

[0025] Specifically, linear slide rails 11 are provided on both sides of the middle of the upper surface of the workbench 1, and the bottom of the movable mounting plate 4 is slidably connected to the linear slide rails 11 to ensure smooth movement.

[0026] Depending on the requirements, the linear guide rail 11 can be a long, integral structure; or it can be two short, two-section structures. When it is a two-section structure, there can be a gap between the two sections to reduce manufacturing costs. For example, when the linear guide rail 11 is 2m long and the travel of the moving mounting plate 4 is 0.5m, the linear guide rail 11 can include two sections of 0.55-0.6m each, with a gap of 0.8-0.9m between the two sections.

[0027] Furthermore, an n-shaped frame 7 is provided above the workbench 1, and a longitudinal guide post 71 is provided at the top of the n-shaped frame 7. The longitudinal guide post 71 passes through the top of the movable mounting plate 4, further guiding the longitudinal movement of the movable mounting plate 4.

[0028] Furthermore, the hydraulic station 10 is located on top of the n-shaped frame 7 to provide hydraulic power for the dual-axis hydraulic cylinder 2.

[0029] In one possible implementation, combined with the appendix Figure 4 The dual-axis hydraulic cylinder 2 includes a cylinder body 21, and a piston plate 22 that is slidably connected to the inner cavity of the cylinder body 21 along its axial direction, thereby dividing the inner cavity of the cylinder body 21 into two chambers; the piston plate 22 has a telescopic shaft 23 that is coaxial with it and extends out of the cylinder body 21 at the middle of both plate surfaces.

[0030] In one possible implementation, combined with the appendix Figure 4 The hydraulic station 10 is connected to the two chambers of the cylinder 21 via two inlet pipes and two return pipes. For example, when bending the workpiece on the left, the hydraulic station 10 supplies hydraulic oil to the right chamber of the cylinder 21 via the corresponding inlet pipe, and the hydraulic oil in the left chamber of the cylinder 21 returns to the hydraulic station 10 via the corresponding return pipe. At this time, the piston plate 22 moves to the left, which in turn drives the telescopic shaft 23 and the movable mounting plate 4 to move to the left, thus bending the workpiece on the left.

[0031] If necessary, the inlet pipe and return pipe on the same side near the cylinder 21 chamber can use the same pipe, and the joint is connected by a solenoid valve.

[0032] In this embodiment, protective outer plates 9 are detachably installed on both sides of the workbench 1 and the n-shaped frame 7 to provide safety protection.

[0033] In this embodiment, the first replaceable module 5 and the second replaceable module 6 have the same structure and are arranged symmetrically. This makes the two stations of the bending device located on the front left and front right sides of the worktable 1, respectively.

[0034] Example 2, in conjunction with Appendix Figure 6An energy-saving locomotive parts bending device differs from Embodiment 1 in that the first replaceable module 5 and the second replaceable module 6 are arranged in a rotationally symmetrical manner, so that the two workstations of the bending device are located on the front left and rear right of the workbench 1, respectively.

[0035] In other embodiments, the first replaceable module 5 and the second replaceable module 6 may also adopt different structures to perform bending operations on different workpieces respectively.

[0036] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the above embodiments should be regarded as exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalents of the claims in this utility model, and no reference numerals in the claims should be regarded as limiting the content of the claims.
