Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam processing technology, and specifically to a foam thermal cutting machine. Background Technology
[0002] In the field of precision instrument and optical component manufacturing, the transport packaging of quartz glass and high-precision components has always been a key focus of the industry. Currently, expanded polystyrene (EPS) and expanded polyethylene (EPE) are the mainstream cushioning materials, occupying approximately 78% of the fragile goods packaging market share due to their excellent shock resistance and plasticity. Especially when handling components with special geometric shapes such as circular optical lenses and annular mechanical seals, customized foam packaging has become the industry standard solution.
[0003] However, traditional processing methods rely on computer numerical control (CNC) foam cutting equipment. While this type of equipment can achieve a processing accuracy of ±0.5mm, its purchase cost is generally as high as 200,000 to 500,000 yuan, and it requires professional technicians to operate. For small and medium-sized manufacturing enterprises, the equipment investment payback period exceeds 3 years, which seriously restricts the upgrading and transformation of the packaging process. In actual operation, operators need to spend 2-3 hours on 3D modeling and toolpath planning, and the material loss rate of a single product is as high as 35%, which makes the packaging cost of a 300mm diameter ring component climb to 45-60 yuan per piece. Utility Model Content
[0004] To address the technical problem of high cost of foam cutting equipment with special shapes, this utility model provides a foam thermal cutting machine. By setting a crossbeam above the worktable and setting a cutting tool and positioning component between the crossbeam and the worktable, the foam is first placed on the worktable and the center of the foam is positioned by the positioning component. Then, the foam is driven to rotate, and the circular processing of the foam is achieved under the action of the cutting tool.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0035] Example
[0036] See Figure 1This embodiment discloses a foam thermal cutting machine, including a worktable 10, a crossbeam 20, a cutting tool 30, and a positioning component 40. Specifically, the worktable 10 is mounted on a horizontal plane, such that the top surface of the worktable 10 is on the horizontal plane. A crossbeam 20 is provided above the worktable 10, and the crossbeam 20 is arranged in a horizontal direction, such that the crossbeam 20 is parallel to the top surface of the worktable 10.
[0037] A cutting tool 30 and a positioning element 40 are provided between the crossbeam 20 and the worktable 10. The cutting tool 30 is slidably disposed on the crossbeam 20 and can reciprocate along the length of the crossbeam 20. The cutting edge of the cutting tool 30 is located on the worktable 10.
[0038] The positioning element 40 is disposed on the crossbeam 20, and its extension direction is perpendicular to the crossbeam 20. The bottom end of the positioning element 40 can extend vertically downward to the worktable 10.
[0039] The extension direction of the positioning element 40 is parallel to the extension direction of the tool 30. When the tool 30 moves, it moves closer to or further away from the positioning element 40.
[0040] During use, the foam is first placed on the worktable 10, and the center of the foam is positioned using the positioning element 40. Then, the position of the cutting tool 30 is adjusted so that the cutting edge of the cutting tool 30 is in the required position. Then, the foam is driven to rotate, and the circular shape of the foam is achieved under the action of the cutting tool 30. When controlling the position of the cutting edge of the cutting tool 30, the distance between it and the positioning element 40 is equal to the radius of the required foam.
[0041] This technical solution has a simple structure and high production efficiency, thereby reducing the overall cost when manufacturing foam parts.
[0042] Preferably, the cutting machine further includes a rotary drive (not shown in the figure), which can directly drive the foam to rotate. Generally, the rotary drive can include a motor and rollers. The motor drives the rollers to rotate, which then presses the rollers onto the foam, thereby driving the foam to rotate. Of course, the rotary drive can also include a lifting mechanism, which drives the motor and rollers to move up and down. The lifting mechanism can generally be a pneumatic or hydraulic system or other mechanical components with rising or falling capabilities.
[0043] Preferably, two sets of cutters 30 are symmetrically arranged on the crossbeam 20, with the two sets of cutters 30 arranged parallel to each other and both capable of moving on the crossbeam 20. By setting two sets of cutters 30, a circular foam board can be processed by simply rotating the foam 180° during use.
[0044] In addition, it can also produce rectangular foam boards of specific sizes. The specific operation involves first adjusting the distance between the two sets of cutters 30, then maintaining a certain distance between the bottom end of the positioning component 40 and the worktable 10 (this distance is greater than or equal to the required thickness of the foam board). The foam is then driven to move linearly on the worktable 10, and the cutters 30 cut the sides of the foam, thus achieving rapid processing of rectangular foam. The processing efficiency is even higher when the sides of the foam material are irregularly shaped.
[0045] In one specific embodiment:
[0046] The cutting tool 30 includes a heating wire 31 and an elastic element 32. One end of the heating wire 31 is slidably mounted on the worktable 10, and the direction of movement of this end of the heating wire 31 is parallel to the length direction of the crossbeam 20. One end of the elastic element 32 is connected to the other end of the heating wire 31, and the other end of the elastic element 32 is slidably mounted on the crossbeam 20.
[0047] Since the heating wire 31 is made of metal, and metal has a significant thermal expansion and contraction phenomenon, an elastic element 32 is provided at the end of the metal wire to compensate for the thermal expansion and contraction of the heating wire 31, so that the heating wire 31 always remains taut.
[0048] Preferably, the elastic element 32 is a device such as a spring, leaf spring, or rubber band that can deform under force and return to its original shape after the external force is removed.
[0049] In another specific embodiment:
[0050] The positioning component 40 includes a positioning rod, which is movably mounted on the crossbeam 20 and vertically placed on the worktable 10. A through hole 21 is provided in the middle of the crossbeam 20, and the positioning rod is disposed within this through hole 21. Additionally, a positioning hole is provided in the middle of the worktable 10, into which the bottom end of the positioning rod can be inserted. The positioning rod is a round rod.
[0051] In use, the positioning rod is passed through the through hole 21 on the crossbeam 20, then through the middle of the foam, and inserted into the positioning hole. This not only positions the foam, but also allows the foam to rotate around the positioning rod as an axis.
[0052] In another specific embodiment:
[0053] Unlike the previous embodiment, the positioning member 40 includes a telescopic rod. The top end of the telescopic rod is fixed on the crossbeam 20, and the bottom end of the telescopic rod can extend and retract and be inserted into the positioning hole. The working principle of the telescopic rod is similar to that of the positioning rod, both of which pass through the foam and are inserted into the positioning hole to position the foam.
[0054] It is understandable that the bottom end of the telescopic rod can be a sleeve structure to achieve the telescopic function.
[0055] In another specific embodiment:
[0056] See Figure 2 , Figure 3 and Figure 4 The cutting machine also includes a drive assembly 50, which is poweredly connected to the cutter 30 and directly drives the cutter 30 to reciprocate on the crossbeam 20. The drive assembly 50 allows for convenient adjustment of the distance between the cutter 30 and the positioning element 40.
[0057] Preferably, the bottom of the cutting tool 30 is slidably mounted on the worktable 10, while both the top and bottom of the cutting tool 30 are poweredly connected to the drive assembly 50. This allows the drive assembly 50 to simultaneously drive the top and bottom of the cutting tool 30 to move, thus making the movement of the cutting tool 30 more stable. The drive assembly 50 can drive two sets of cutting tools 30 on the crossbeam 20 to move in opposite directions or towards each other.
[0058] Specifically, the crossbeam 20 has the aforementioned through hole 21 in its middle. A first through groove 58 is provided on each side of the through hole 21. A first screw 51 is rotatably mounted above each of the first through grooves 58, with both ends of the first screw 51 rotatably mounted on the crossbeam 20. The two first screws 51 are connected by three bevel gears 52. A first slider 53 is fitted onto each of the two first screws 51. Each of the two first sliders 53 passes through a first through groove 58 and is then connected to an elastic element 32 on a cutting tool 30.
[0059] A second through slot 54 is provided on both sides of the positioning hole of the worktable 10. A second screw 55 is rotatably provided below each of the two second through slots 54. The ends of the two second screws 55 are also poweredly connected by three bevel gears 52. The end of one first screw 51 is poweredly connected to the end of one second screw 55 through a pulley mechanism 56. A second slider 57 is matched on each of the two second screws 55. The two second sliders 57 are slidably disposed in one of the second through slots 54. The ends of the two second sliders 57 are respectively connected to the bottom end of the heating wire 31 of a tool 30.
[0060] In this embodiment, the first screw 51 and the second screw 55 can be driven to rotate by a servo motor. During use, two sets of bevel gears 52 cause the two first screws 51 to rotate in opposite directions, and the two second screws 55 to rotate in opposite directions as well, thereby causing the two sets of cutters 30 to move closer or further apart. Furthermore, the pulley mechanism 56 ensures that the first screw 51 and the second screw 55 on the same side of the positioning member 40 rotate in the same direction. The cutter 30 is then driven to move by the first slider 53 and the second slider 57 on the same side of the positioning member 40.
[0061] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
