Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to an expandable polystyrene cutting device. Background Technology

[0002] Expandable polystyrene (EPS foam) is a material that is easily melted and dispersed. After being foamed into sheet materials, some parts require precise cutting to meet practical application requirements. Traditional cutting methods use blade-type cutting, which can easily lead to workpiece breakage. In existing technologies, electrothermal cutting wires can also be used for cutting. Specifically, an environmentally friendly EPS foam cutting device provided by patent CN218255620U can be used. This device includes a support base box, with bottom pads evenly and horizontally aligned on the bottom surface of the support base box. A control panel is embedded in one side of the support base box, and a support plate is vertically bolted to one side of the support base box. A horizontal connecting rod is horizontally welded to one side of the support plate, and an electrothermal cutting wire is vertically inserted into the bottom surface of the horizontal connecting rod. A through hole is horizontally opened on the top surface of the support base box, and a guide side plate is horizontally arranged on the top surface of the support base box. Bottom screw holes are evenly opened on the bottom surface of the support base box. Using a heated wire cutting method makes the foam cutting cleaner and more thorough, preventing burrs or foam ball splattering. Simultaneously, the intelligent distance control structure allows for adjustment of the cutting size of the foam board as needed, greatly improving the efficiency of foam board cutting. However, in actual use, the workpiece itself may shift, affecting the cutting accuracy. Utility Model Content

This solution provides slide rails and a movable table that can reciprocate on the slide rails on the mounting frame. The positioning holes on the movable table assist in positioning the workpiece, and then the movable table assists in moving the workpiece and achieving cutting. During the process, the workpiece is less likely to shift, thus ensuring cutting accuracy and solving the problem in the prior art where workpiece shifting can affect cutting accuracy.

[0005] Furthermore, a first mounting end and a second mounting end are respectively connected to the mounting arm and the mounting bracket, and the two ends of the electrothermal cutting wire are respectively connected to the first mounting end and the second mounting end.

[0006] Furthermore, the mounting arm includes a first arm segment fixed to the mounting bracket and a second arm segment perpendicular to the first arm segment, with a first mounting end installed at the end of the second arm segment.

[0007] Furthermore, both the first arm segment and the second arm segment have U-shaped cross-sections, and a first reinforcing plate is fixedly installed at the connection between them. The first reinforcing plate has through holes to connect the U-shaped structures of the first arm segment and the second arm segment.

[0008] Furthermore, a distribution box is also installed on the mounting frame. A connecting wire is provided between the distribution box and the first mounting end, and the connecting wire passes through the U-shaped structure of the first arm segment, the through hole, and the U-shaped structure of the second arm segment.

[0009] Furthermore, a second reinforcing plate is fixedly connected between the first arm segment and the second arm segment.

[0010] Furthermore, the mounting bracket includes a mounting plate, two slide rails, and a second mounting end, which are respectively mounted on the mounting plate.

[0011] Furthermore, a pair of limiting plates are fixedly connected to the mounting plate, located between the two ends of the two slide rails, and the moving platform reciprocates between the two limiting plates.

[0012] Furthermore, sliding blocks are fixedly connected to the four corners of the movable platform, and the sliding blocks are slidably connected to the slide rail.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The movable platform that can move on the mounting frame and the positioning holes thereon can help position the workpiece. Then, the movable platform helps the workpiece move and achieve cutting. During the process, the workpiece is not easy to deviate, thus ensuring cutting accuracy. This solves the problem in the prior art where the cutting accuracy is affected by the possibility of workpiece deviation. Attached Figure Description

Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1-4As shown, this embodiment provides an expandable polystyrene cutting device, which includes a mounting frame 1. A mounting plate 2 is fixedly connected to the top surface of the mounting frame 1. A pair of parallel slide rails 3 are fixedly connected to the mounting plate 2. The device also includes a movable platform 4, which can be a square structure, and sliding blocks 5 are fixedly connected to the four corners of one side of the platform. Two sliding blocks 5 located on the same side are slidably connected to one of the slide rails 3, so that the movable platform 4 can move back and forth above the mounting plate 2. Furthermore, the movable platform 4 also has openings... The mounting bracket 1 is provided with several positioning holes 6 and a strip frame 7 parallel to the two slide rails 3. The strip frame 7 is located in the middle of the moving platform 4 and the positioning holes 6 are arranged in regular rows and symmetrically on both sides of the strip frame 7. The mounting bracket 1 is also fixedly connected to a mounting arm 8 that extends upward to the top of the moving platform 4. The mounting arm 8 is also connected to a first mounting end 9 located directly above the strip frame 7. The mounting plate 2 is also connected to a second mounting end 10. An electrothermal cutting wire 11 passing through the strip frame 7 is connected between the first mounting end 9 and the second mounting end 10. In this solution, the movable table 4 is used to place the workpiece, and the positioning holes 6 can be used to position the workpiece. For example, a "7"-shaped positioning element can be used, with one end inserted into the positioning hole 6 and the other end providing downward pressure on the upper wall of the workpiece to position it on the movable table 4. Then, the movable table 4 assists in moving the workpiece and achieving cutting. During the process, the workpiece is less likely to shift, thus ensuring cutting accuracy and solving the problem in the prior art where workpiece shift may affect cutting accuracy. Furthermore, the strip frame 7 has... The moving table 4 has a relatively large width to ensure that it does not come into contact with the electrothermal cutting wire 11 during movement. Furthermore, a pair of limiting plates 12 are fixedly connected to the mounting plate 2, located between the two ends of the two slide rails 3. The two limiting plates 12 extend upward and abut against the moving table 4 during the reciprocating motion between the moving table 4 and the two limiting plates 12, thereby limiting the moving table 4 and preventing it from accidentally detaching. In particular, the upper surface of the limiting plate 12 is lower than the upper surface of the moving table 4, which can prevent the workpiece from colliding with the limiting plate 12.

[0017] In this scheme, the positioning component includes a rod 13 and a pressure plate 14 fixedly connected thereto. The rod 13 can be inserted into the positioning hole 6, while the pressure plate 14 presses on the workpiece, thereby achieving the positioning of the workpiece. In order to facilitate the removal of the workpiece, an ear plate 15 is also fixedly connected to the pressure plate 14, which can be held by the operator and lifted to remove the positioning component.

[0018] In a further embodiment, the mounting arm 8 includes a first arm segment 16 fixedly connected to one side of the mounting frame 1 and extending upward, and a second arm segment 17 fixedly connected to the upper end of the first arm segment 16. A first mounting end 9 is connected to the end of the second arm segment 17 facing away from the first arm segment 16. A distribution box 18 is also mounted on the mounting frame 1, and a connecting wire 19 is provided between the distribution box 18 and the first mounting end 9. Furthermore, the cross-sections of the first arm segment 16 and the second arm segment 17 are both U-shaped, thus enabling them to have better performance. In addition to improving the mechanical strength, the connecting wires 19 can also be located within their U-shaped structures. A first reinforcing plate 20 located between the two U-shaped structures is also fixedly connected at the connection between the first arm segment 16 and the second arm segment 17. The first reinforcing plate 20 has a through hole to connect the U-shaped structures of the first arm segment 16 and the second arm segment 17, and the through hole provides a channel for the connecting wires 19. Furthermore, a second reinforcing plate 21 is also fixedly connected at the angle between the first arm segment 16 and the second arm segment 17 to improve the overall mechanical strength of the mounting arm 8.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
