Description

Technical Field

[0001] This utility model relates to the field of electromagnetic forming equipment technology, and in particular to a liftable insulated worktable for electromagnetic forming equipment. Background Technology

[0002] In the field of electromagnetic forming technology, the worktable, as a key component that supports the workpiece and performs forming operations, directly affects the efficiency and safety of the entire production process through its performance and ease of operation. Traditional electromagnetic forming equipment mostly uses a fixed design for its worktables, making height adjustment impossible. To address this issue, some worktable designs with lifting functions have gradually emerged in the market. However, these lifting worktables still have many shortcomings in terms of automation and structural stability. For example, some lifting worktables still rely on manual operation for raising and lowering, which is not only inefficient but also poses a significant safety risk due to the high voltage environment of electromagnetic forming equipment. Furthermore, the existing worktable surfaces are not insulated, resulting in residual current after each use. This current requires a considerable amount of time or the use of other equipment to remove, leading to high time and economic costs. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a liftable insulated worktable for electromagnetic forming equipment, so as to solve the problems of non-automatic lifting of the worktable and non-insulated table surface in the existing electromagnetic forming equipment.

[0004] To achieve the above objectives, this utility model proposes a liftable insulated worktable for an electromagnetic forming equipment, comprising a lifting mechanism and a work platform. The lifting mechanism includes a base, above which two linkage mechanisms are symmetrically arranged. Each linkage mechanism includes a guide rail extending forward and backward. A slider is slidably connected to both the front and rear ends of the guide rail. A slider seat is fixed on each slider. All slider seats on the same side are connected in series via a threaded rod extending forward and backward. The threaded rod and the slider seat are threadedly engaged, and a first synchronous pulley is coaxially fixed in the middle of the threaded rod. The threads on both sides of the threaded rod are divided by the first synchronous pulley. The work platform is constructed using insulating material and is fixed to the upper side of the upper seat. Two pads are provided on both sides of the bottom surface of the upper seat corresponding to the two guide rails. A fixed seat is provided on the bottom surface of each pad corresponding to each slider seat below it. The fixed seat and slider seat are connected by a connecting rod, which is hinged to both the fixed seat and the slider seat. The connecting rod at the front end of the guide rail and the connecting rod at the rear end of the guide rail are symmetrically arranged. A motor is also fixed on the platform, located between two first synchronous pulleys. A second synchronous pulley is coaxially fixed on the output shaft of the motor, and the second synchronous pulley is connected to the two first synchronous pulleys via belts.

[0005] In the above scheme, the linkage mechanism includes four links, two of which are parallel to each other and located at the front end of the threaded rod, and the other two are parallel to each other and located at the rear end of the threaded rod. This design not only enhances the overall rigidity of the linkage mechanism but also improves the stability during the lifting process.

[0006] In the above scheme: the working platform is made of ceramic material or polyetheretherketone (PEEK) material. Both ceramic and polyetheretherketone (PEEK) are materials with excellent insulation properties.

[0007] In the above scheme: the linkage mechanism also includes a U-shaped boss extending forward and backward, the U-shaped boss is fixed on the platform, the guide rail is fixed inside the U-shaped boss, and the U-shaped boss plays a protective role for the guide rail and the slider.

[0008] In the above solution: the upper seat is welded and fixed above the two gaskets, and the work platform is bonded or bolted to the upper seat. The structure is simple and easy to assemble. The welded connection between the gaskets and the upper seat forms a single integrated structure, providing full support under the work platform, which improves the load-bearing capacity of the work platform. This is crucial for ensuring the reliability and safety of the work platform during long-term use.

[0009] In the above scheme: the ends of the threaded rod at both ends are fixed to the guide rail by brackets, and the threaded rod and the brackets are rotatably connected by bearings to enhance the stability of the structure (not shown in the figure).

[0010] The beneficial effects of this utility model are as follows: 1. The coordinated design of the linkage mechanism and the threaded rod ensures the smoothness and precision of the lifting process. The threads on both sides of the threaded rod are arranged in opposite directions with the synchronous wheel as the dividing line, so that the slider can generate relative motion when the motor rotates forward and reverse, thereby driving the linkage mechanism to stably lift and lower the work platform. This not only improves operating efficiency but also reduces reliance on manual operation and lowers the safety risks during operation. 2. The work platform is made of insulating material, avoiding the problem of residual current on the surface after the equipment is used, effectively reducing the time and economic costs of dealing with residual current.

[0011] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] Figure 2 yes Figure 1 A diagram from another angle. Detailed Implementation

[0014] like Figure 1As shown in Figure 2, a liftable insulated worktable for an electromagnetic forming equipment mainly consists of a lifting mechanism and a work platform 1.

[0015] The lifting mechanism includes a platform 2, which is bolted to the top of the electromagnetic forming equipment. Two linkage mechanisms are symmetrically arranged on the left and right sides above the platform 2. The linkage mechanism includes a guide rail 3 extending forward and backward. A slider 4 is slidably connected to the front and rear ends of the guide rail 3. A slider seat 5 is fixed on the slider 4. All slider seats 5 on the same side are connected in series by threaded rods 6 extending forward and backward. The threaded rods 6 and the slider seats 5 are threadedly engaged. A first synchronous pulley 7 is coaxially fixed in the middle of the threaded rod 6. The threads on both sides of the threaded rod 6 are arranged in opposite directions with the first synchronous pulley 6 as the dividing line.

[0016] The working platform 1 is made of insulating material and is fixed to the upper side of the upper seat 8. Two pads 9 are provided on both sides of the bottom surface of the upper seat 8 corresponding to the two guide rails 3. On the bottom surface of the pads 9, a fixed seat 10 is provided for each slider seat 5 on the same side below. The fixed seat 10 and the slider seat 5 are connected by a connecting rod 11. The connecting rod 11 is hinged to both the fixed seat 10 and the slider seat 5. The connecting rod 11 at the front end of the guide rail 3 and the connecting rod 11 at the rear end of the guide rail 3 are arranged symmetrically.

[0017] A motor 12 is also fixed on the platform 2. The motor 12 is located between the two first synchronous pulleys 7. A second synchronous pulley 13 is coaxially fixed on the output shaft of the motor 12. The second synchronous pulley 13 is connected to the two first synchronous pulleys 7 by belts. When the motor 12 starts, it drives the first synchronous pulleys 7 to rotate through the belt, thereby causing the slider 4 on the guide rail 3 to move relative to each other, which in turn drives the connecting rod 11 to move, realizing the automatic lifting and lowering of the work platform 1. By controlling the forward and reverse rotation of the motor 12, the lifting and lowering control of the work platform 1 can also be realized.

[0018] Ideally, the linkage mechanism comprises four links 11, with two links 11 parallel to each other and positioned at the front end of the threaded rod 6, and the other two links 11 parallel to each other and positioned at the rear end of the threaded rod 6. This design not only enhances the overall rigidity of the linkage mechanism but also improves stability during lifting.

[0019] Ideally, the work platform 1 should be made of ceramic or polyetheretherketone (PEEK) material, both of which are materials with excellent insulating properties.

[0020] Preferably, the linkage mechanism also includes a U-shaped boss 14 extending forward and backward, the U-shaped boss 14 being fixed on the base 1, the guide rail 3 being fixed inside the U-shaped boss 14, and the U-shaped boss 14 protecting the guide rail 3 and the slider 4.

[0021] Ideally, the upper seat 8 is welded and fixed above the two gaskets 9, and the work platform 1 is glued or bolted to the upper seat 8. This design is simple, easy to assemble, and the welded connection between the gaskets 9 and the upper seat 8 forms a single integrated structure, providing full support for the work platform 1. This improves the load-bearing capacity of the work platform 1, which is crucial for ensuring its reliability and safety during long-term use.

[0022] Ideally, the ends of the threaded rod 6 at both ends are fixed to the guide rail 3 by brackets, and the threaded rod 6 is rotatably connected to the brackets by bearings to enhance the stability of the structure (not shown in the figure).
