Description

Technical Field

[0001] This application relates to the field of electrothermal cutting technology, specifically to an electrothermal cutting device. Background Technology

[0002] A hot wire cutter is a machine that uses the heat from a hot wire to achieve the purpose of cutting. Hot wire cutters are mainly used for cutting foam sponges, filter screens, chemical fiber cloths, woven bags, etc.

[0003] Some electric hot wire cutting machines on the market include an operating table, an angle plate, and a guide ruler. The angle plate is set on the operating table, and the guide ruler is fixed on the angle plate. The guide ruler can move back and forth relative to the angle plate and can be fixed on the angle plate by tightening the nut. However, in the actual operation of the electric hot wire cutting machine, due to the excessive size of some materials to be cut, the materials to be cut are too high and the contact area between the materials to be cut and the guide ruler is too small. When pushing the materials to be cut forward or backward, the center of gravity is very unstable and easy to slip, resulting in cutting failure. In severe cases, it may even cause dangerous situations such as skin burns from the hot wire. Utility Model Content

[0060] Please refer to Figures 1 to 3This application provides an electrothermal cutting device for cutting a workpiece 10 to be cut. The electrothermal cutting device includes an operating table 20, a support assembly, a positioning assembly, a heating wire 30, a first guide ruler 40, and a second guide ruler 41.

[0061] Specifically, the operating table 20 is used to support the workpiece 10 to be cut; the operating table 20 constitutes the main part of the electrothermal cutting device, not only supporting the workpiece 10 to be cut, but also other components of the electrothermal cutting device are installed based on the operating table 20. The operating table 20 can be a rectangular or near-rectangular shell with a hollow interior, and some components of the electrothermal cutting device can be installed in the hollow position inside the operating table 20.

[0062] The support assembly is disposed on the operating table 20; the support assembly has two opposite ends, one end of which is connected to the operating table 20 and the other end is used to connect to the heating wire 30.

[0063] The positioning component is provided on the operating table 20; the positioning component is located on the side surface of the operating table 20 corresponding to the support component, so that the heating wire 30 can be installed on the operating table 20 by means of the support component and the positioning component.

[0064] The heating wire 30 is disposed between the support assembly and the positioning assembly to cut the workpiece 10 to be cut located on the operating table 20. The heating wire 30 can be installed and tensioned through the support assembly and the positioning assembly, and the workpiece 10 to be cut can be moved on the operating table 20. When passing the heating wire 30, the workpiece 10 to be cut can be cut.

[0065] The first guide ruler 40 is movably mounted on the operating table 20; the first guide ruler 40 moves linearly and / or rotates relative to the operating table 20 in order to adjust the relative position between the first guide ruler 40 and the heating wire 30, so as to meet the various types of cutting requirements of the workpiece 10 to be cut.

[0066] The second guide ruler 41 is connected to the first guide ruler 40. The end of the second guide ruler 41 away from the operating table 20 is higher than the end of the first guide ruler 40 away from the operating table 20. The second guide ruler is configured to guide the workpiece 10 to be cut along the second guide ruler 41 on the operating table 20. The first guide ruler 40 can be a long strip-shaped structure, and the second guide ruler 41 can be a plate-shaped structure with approximately the same length as the first guide ruler 40. The side of the second guide ruler 41 at the connection point with the workpiece 10 is set to a flat and smooth surface to reduce the friction between the workpiece 10 and the second guide ruler 41. The side of the first guide ruler 40 closest to the operating table 20 is the bottom surface of the first guide ruler 40, and the side of the first guide ruler 40 furthest from the operating table 20 is the top surface of the first guide ruler 40. The side of the second guide ruler 41 closest to the operating table 20 is the bottom surface of the second guide ruler 41, and the side of the second guide ruler 41 furthest from the operating table 20 is the top surface of the second guide ruler 41. The top surface of the second guide ruler 41 is higher than the top surface of the first guide ruler 40. That is, the second guide ruler 41 can increase the attachment area of ​​the workpiece 10 to be cut during the movement along the first guide ruler 40, thereby improving the stability of the large workpiece 10 during the electrothermal cutting process.

[0067] In the above manner, a second guide ruler 41 is set on one side of the first guide ruler 40, and the end of the second guide ruler 41 away from the operating table 20 is kept higher than the end of the first guide ruler 40 away from the operating table 20. The second guide ruler 41 has a higher height than the first guide ruler 40, so that the workpiece 10 to be cut can move along the second guide ruler 41 on the operating table 20 for cutting. The higher second guide ruler 41 can increase the contact area for the large workpiece 10 to be cut, improve the support effect of the workpiece 10 to be cut, and help keep the center of gravity of the workpiece to be cut stable when pushing the workpiece 10 to be cut forward or backward on the operating table 20, reduce the possibility of the workpiece 10 to be cut sliding sideways, ensure the smooth progress of the cutting process of the workpiece 10 to be cut, prevent safety accidents such as skin burns caused by the heating wire 30, and improve the safety performance of the device during use.

[0068] In one embodiment, the second guide ruler 41 and the first guide ruler 40 are integral structural components. The second guide ruler 41 and the first guide ruler 40 can be die-cast parts formed by die casting, injection molded parts formed by injection molding, or stamped parts formed by stamping. In this case, the second guide ruler 41 and the first guide ruler 40 are integral structural components, and the second guide ruler 41 is equivalent to an extension of the first guide ruler 40. Setting the second guide ruler 41 and the first guide ruler 40 as integral structural components can improve the overall strength of the second guide ruler 41 and the first guide ruler 40, improve the stability of the workpiece 10 to be cut along the second guide ruler 41, prevent the workpiece 10 to be cut from moving due to the swaying of the second guide ruler 41 relative to the first guide ruler 40 during the movement, ensure the stability of the workpiece 10 to be cut on the operating table 20, and ensure the cutting quality of the workpiece 10 by the heating wire 30.

[0069] It should be noted that the second guide ruler 41 and the first guide ruler 40 can be made by die casting, injection molding or stamping depending on their materials. Of course, the second guide ruler 41 and the first guide ruler 40 can also be made by other methods in the existing technology, and no single limitation is made here.

[0070] In one embodiment, the second guide ruler 41 and the first guide ruler 40 are separate structural components. The second guide ruler 41 and the first guide ruler 40 can be adhesive components connected by bonding, welded components connected by welding, or assemblies connected by screw assemblies or rivets. In this case, the second guide ruler 41 and the first guide ruler 40 are separate structural components. The first guide ruler 40 and the second guide ruler 41 are independent components before being connected. Setting the second guide ruler 41 and the first guide ruler 40 as separate structural components allows for the selection of different heights of the second guide ruler 41 according to the size of the workpiece 10 to be cut, so as to adapt to various sizes of workpieces 10 to be cut, thus making the electrothermal cutting device have a wider range of applications.

[0071] It should be noted that the second straightedge 41 and the first straightedge 40 can be connected by bonding, welding, screw assembly or riveting depending on their materials. Of course, the second straightedge 41 and the first straightedge 40 can also be connected by other methods in the prior art, which are not limited here.

[0072] In one embodiment, please continue to refer to Figures 1 to 3 The support assembly includes a support arm 21 and a tilt adjustment mechanism; the tilt adjustment mechanism includes a movable seat 22, a first locking member 220 and a second locking member 221.

[0073] Specifically, the movable seat 22 is installed on the support arm 21; one end of the support arm 21 is fixed to the operating table 20, and the other end is located above the operating table 20. The movable seat 22 is slidably sleeved on the support arm 21. By adjusting the position of the movable seat 22 on the support arm 21, the tilt state of the heating wire 30 can be adjusted to meet the cutting of various types of workpieces 10 to be cut.

[0074] The first locking member 220 is used to fix the movable seat 22 onto the support arm 21. The first locking member 220 can be a screw, which is threaded to one side wall of the movable seat 22. By rotating the screw, the inner end of the screw can be made to abut against the support arm 21. After the movable seat 22 is adjusted to the target position along the support arm 21, the movable seat 22 can be fixed by tightening the screw to prevent the movable seat 22 from continuing to move on the support arm 21.

[0075] The second locking member 221 is used to fix the top end of the heating wire 30. The second locking member 221 can also be a screw. The screw is threaded to the top wall of the movable seat 22. The heating wire 30 can be fixed on the movable seat 22 by the second locking member 221, thereby fixing one end of the heating wire 30.

[0076] Furthermore, referring to Figures 4 to 6 The positioning component includes a positioning block 23 and a third locking element 231.

[0077] Specifically, the positioning block 23 is set on the operating table 20, and the positioning block 23 has a positioning channel 230 inside, and the bottom end of the heating wire 30 is located in the positioning channel 230; the positioning block 23 is embedded on the upper surface of the operating table 20, and the positioning channel 230 is set through the positioning block 23, so that the heating wire 30 can be inserted into the positioning block 23 through the positioning channel 230.

[0078] It should be noted that a tapered transition hole is provided at one end of the positioning channel 230 near the upper surface of the operating table 20. The tapered transition hole can prevent the top edge of the positioning channel 230 from wearing down the heating wire 30 when the heating wire 30 is in an inclined state, which helps to extend the service life of the heating wire 30.

[0079] The third locking member 231 is installed on the operating table 20 to fix the heating wire 30 in the positioning channel 230. The third locking member 231 can be a screw, which can be threaded to the front wall of the operating table 20. At this time, the side wall of the positioning block 23 is provided with a side hole for the end of the screw to be inserted. By screwing the screw, the heating wire 30 located in the positioning channel 230 can be fixed in the positioning block 23, thereby fixing the bottom end of the heating wire 30.

[0080] Of course, in some other embodiments, the screw can also be rotatably connected to the front wall of the operating table 20. In this case, the side wall of the positioning block 23 is provided with a screw hole for matching the end of the screw. By screwing the screw, the heating wire 30 located in the positioning channel 230 can be fixed in the positioning block 23, and the bottom end of the heating wire 30 can also be fixed.

[0081] It should be noted that when the third locking element 231 is selected as a screw, the position of the inner wall of the positioning channel 230 relative to the end of the screw is set as a plane, so that the end face of the screw can cooperate with the plane in the positioning channel 230 to clamp and fix the bottom end of the heating wire 30.

[0082] In one embodiment, please continue to refer to Figures 1 to 3The second locking member 221 is equipped with a winding disc 222. The top end of the heating wire 30 is fixed to the winding disc 222, which is used to wind the heating wire 30 by rotating the winding disc 222. The second locking member 221 is used to fix the winding disc 222. Specifically, when the second locking member 221 is a screw, the screw is threaded to the top wall of the movable seat 22. The winding disc 222 has a through hole in the center for the screw to pass through. Since one end of the heating wire 30 is fixedly connected to the winding disc 222, the heating wire 30 can be wound by rotating the winding disc 222, so that the heating wire 30 is adjusted to a tensioned state. Subsequently, turning the screw can clamp and fix the winding disc 222 to the movable seat 22, preventing the winding disc 222 from rotating back and causing the heating wire 30 to loosen.

[0083] It should be noted that a guide groove is provided on the side wall of the movable seat 22 for guiding the heating wire 30. The heating wire 30 can be prevented from shifting left and right relative to the movable seat 22 through the guide groove, thus ensuring the stability of the heating wire 30 during the cutting process.

[0084] In one embodiment, please refer to Figure 4 The electrothermal cutting device also includes an electrical box 24, which is installed on the operating table 20 and electrically connected to both ends of the heating wire 30. The electrical box 24 may integrate a battery or be directly connected to an external power source to provide power for the operation of the heating wire 30. Simultaneously, the electrical box 24 may integrate one or more of a power adjustment knob 240, a control switch 241, and a foot switch socket 242. These components extend from the inside of the operating table 20 through the side wall to the outside, facilitating manual operation. The power adjustment knob 240 adjusts the heating efficiency of the heating wire 30 to meet the cutting requirements of the workpiece 10. The control switch 241 has three positions: normally open, off, and foot switch control. When the control switch 241 is in the foot switch control position, the foot switch can be connected to the foot switch socket 242 to control the operation of the electrothermal cutting device via foot pedal control, making the control method more flexible and convenient.

[0085] In one embodiment, please Figures 1 to 3 Further reference Figure 7 and Figure 8 The electrothermal cutting device also includes a position adjustment assembly for adjusting the first guide ruler 40 and the second guide ruler 41. The position adjustment assembly includes a linear adjustment mechanism, which includes a guide channel 25, a guide member 50, a base block 51, and a limiting kit.

[0086] Specifically, the guide channel 25 is provided on the operating table 20; the guide channel 25 may be a slide extending along the length direction of the upper surface of the operating table 20, or a slide extending approximately along the width direction of the upper surface of the operating table 20, or a combination of two slides extending approximately along the length and width directions of the upper surface of the operating table 20 respectively.

[0087] The guide member 50 is installed in the guide channel 25 and is connected to the first guide ruler 40 to drive the first guide ruler 40 to move on the operating table 20. The guide member 50 can be a strip plate structure adapted to the guide channel 25. Through the cooperation between the guide member 50 and the guide channel 25, the position of the first guide ruler 40 on the operating table 20 can be adjusted. Furthermore, the relative position of the first guide ruler 40 and the heating wire 30 can be changed to realize more than 10 types of cutting operations on the workpiece to be cut.

[0088] The base block 51 is disposed on the guide member 50; the base block 51 can be fixedly connected to the guide member 50, and the base block 51 can be a cylinder or a frustum structure.

[0089] A limiting device is mounted on the base block 51 to fix the guide member 50 within the guide channel 25. By adjusting the position of the guide member 50 within the guide channel 25, once the relative position of the first guide ruler 40 and the heating wire 30 is adjusted to the target position, the limiting device can fix the guide member 50 within the guide channel 25, preventing it from moving within the guide channel 25 during the operation of the electrothermal cutting device and affecting the cutting accuracy of the workpiece 10.

[0090] In one embodiment, please refer to Figures 9 to 13 The limiting kit includes a first receiving groove 510, a second receiving groove 500, a limiting member 52, and a fourth locking member 53.

[0091] Specifically, the first receiving groove 510 is located on the surface where the base block 51 connects with the guide member 50; one end of the first receiving groove 510 can extend from the inside of the base block 51 to the edge of the base block 51.

[0092] The second receiving groove 500 is located on the side wall of the guide member 50 and is connected to the first receiving groove 510. The second receiving groove 500 is a groove opened on the side wall of the guide member 50. The top of the second receiving groove 500 is connected to the end of the first receiving groove 510 located inside the base block 51, so that the overall space formed by the second receiving groove 500 and the first receiving groove 510 can accommodate the limiting member 52.

[0093] The limiting member 52 is located within the first receiving groove 510 and the second receiving groove 500, and the limiting member 52 is configured to move along the first receiving groove 510. The portion of the limiting member 52 located within the first receiving groove 510 is provided with a first through hole 520, and the first through hole 520 has a driving cone surface 521. The limiting member 52 can be an L-shaped plate, with a portion of the L-shaped plate located in the first receiving groove 510 and another portion of the L-shaped plate located in the second receiving groove 500. The first through hole 520 is located in the portion of the L-shaped plate located in the first receiving groove 510, and the driving cone surface 521 is located at one end of the first through hole 520 and the bottom wall of the first receiving groove 510.

[0094] The fourth locking member 53 is connected to the base block 51 and interacts with the driving cone surface 521, enabling the limiting member 52 to move along the first receiving groove 510 and press against the guide channel 25. The fourth locking member 53 can be a screw. The base block 51 is provided with a threaded hole that is adapted to the screw and extends along the thickness direction. By screwing the screw, it can be moved relative to the base block 51 along its thickness direction. When one end of the screw located inside the threaded hole contacts the side wall of the driving cone surface 521, it can interact with the side wall of the driving cone surface 521, causing part of the limiting member 52 to move along the first receiving groove 510 and the other part to move along the second receiving groove 500 until it abuts against the side wall of the guide slide. Thus, the guide member 50 can be fixed in the guide channel 25, preventing the guide member 50 from moving in the guide channel 25 when the electrothermal cutting device is working, which would affect the cutting accuracy of the workpiece 10 to be cut.

[0095] In this embodiment, a pin 530 is provided at the end where the fourth locking member 53 interacts with the driving cone surface 521. The edge of the connecting end face of the fourth locking member 53 and the pin 530 is set with a chamfer that is adapted to the driving cone surface 521. Thus, when the limiting member 52 is fixed to the side wall of the guide channel 25 by the fourth locking member 53, the pin 530 can be inserted into the first through hole 520. The chamfer of the connecting end face of the fourth locking member 53 and the pin 530 can be completely fitted with the driving cone surface 521, which improves the stability of the cooperation between the fourth locking member 53 and the limiting member 52, and makes the limiting member 52 more stable in the first receiving groove 510 and the second receiving groove 500, which helps the guide member 50 to maintain a more stable state in the guide channel 25.

[0096] In addition, the surface of the guide member 50 connected to the first receiving groove 510 can also be provided with a second through hole 501. When the chamfer of the end face of the fourth locking member 53 and the ejector pin 530 is in contact with the driving cone surface 521, the ejector pin 530 can pass through the first through hole 520 and then be inserted into the second through hole 501, which can further improve the fixing effect of the fourth locking member 53 on the limiting member 52 and further ensure the stability of the limiting member 52 abutting against the side wall of the guide channel 25.

[0097] In one embodiment, please Figure 7 , Figure 8 Further reference Figure 14 The position adjustment assembly also includes an angle adjustment mechanism, which includes a bearing plate 60 and a fifth locking element 61.

[0098] Specifically, the support plate 60 is rotatably connected to the base block 51, and the support plate 60 is connected to the first guide ruler 40 to drive the first guide ruler 40 to rotate on the operating table 20. The support plate 60 is provided with an arc groove 600; the support plate 60 is provided with a rotating hole corresponding to the base block 51, and the support plate 60 can rotate around the base block 51. The support plate 60 has an arc-shaped boundary and a straight boundary. The first guide ruler 40 is set on the straight boundary of the support plate 60, and an angle mark is provided on the surface of the arc-shaped boundary of the support plate 60. The angle mark facilitates the adjustment of the rotation angle of the support plate 60 and the first guide ruler 40.

[0099] The fifth locking member 61 is connected to the guide member 50 and located in the arc groove 600. The fifth locking member 61 is used to fix the bearing plate 60 on the guide member 50. The fifth locking member 61 can be a screw. The guide member 50 is provided with a screw hole corresponding to the fifth locking member 61. When the bearing plate 60 rotates around the base block 51, the fifth locking member 61 can move in the arc groove 600. When the bearing plate 60 is adjusted to the target angle position, the end of the fifth locking member 61 can be pressed down on the bearing plate 60 by screwing it, so as to fix the bearing plate 60 on the guide member 50, thereby realizing the positioning of the first straightedge 40 and preventing the bearing plate 60 from rotating when the electrothermal cutting device is working, which would affect the cutting accuracy of the workpiece 10 to be cut.

[0100] In this embodiment, the guide member 50 is provided with a pointer 54 corresponding to the angle scale on the arc-shaped boundary of the support plate 60. The pointer 54 facilitates the observation of the angle on the angle scale, thereby improving the rotation adjustment efficiency of the support plate 60.

[0101] In one embodiment, please continue to refer to Figure 14 A sliding assembly is provided between the bearing plate 60 and the first guide ruler 40. The sliding assembly includes a sub-slider 62, a female slider 42 and a sixth locking member 63.

[0102] Specifically, the sub-slider 62 is disposed on the bearing plate 60; the sub-slider 62 can be a T-shaped guide rail disposed along the straight boundary of the bearing plate 60.

[0103] The female sliding member 42 is disposed on the first guide ruler 40 and is configured to move along the female sliding member 62. The female sliding member 42 can be a rail sleeve disposed along the length direction of the first guide ruler 40. The rail sleeve is adapted to the T-shaped guide rail. The first guide ruler 40 can slide along the T-shaped guide rail through the rail sleeve, thereby adjusting the relative positions of the first guide ruler 40 and the second guide ruler 41 relative to the bearing plate 60 and the heating wire 30. This allows the workpiece to be cut 10 to move along the second guide ruler 41 and cut the target product without moving the guide member 50 in the guide channel 25, simplifying the adjustment process of the electrothermal cutting device and improving the cutting efficiency.

[0104] The sixth locking member 63 is installed on the support plate 60. The sixth locking member 63 is used to fix the female sliding member 42 on the male sliding member 62. The sixth locking member 63 can be a screw. The support plate 60 is provided with a screw hole corresponding to the sixth locking member 63. Tightening the sixth locking member 63 can cause its end to press down on the female sliding member 42, thereby fixing the position of the female sliding member 42 on the male sliding member 62. This prevents the first guide ruler 40 from moving relative to the support plate 60 when the electrothermal cutting device is working, which would affect the cutting accuracy of the workpiece 10 to be cut, and can also ensure the safety of the cutting operation.
