Description

Technical Field

[0001] The invention relates to the field of cutting technology, in particular to a highly efficient and stable cutting device for graphite coils. Background Art

[0002] Graphite coils are acid and corrosion resistant, high temperature resistant, electrically conductive and thermally conductive, and are therefore widely used in dynamic and static sealing of machines, pipes, pumps and valves in the petroleum, alchemy, chemical, power generation, machinery and other industries.

[0003] Before using, graphite coils are often unrolled and cut by a cutting device. The patent document with the announcement number CN218024581U discloses a single-axis precision coil cutter. When using the coil cutter, a whole roll of graphite coil is first inserted on the placement shaft, the placement shaft is controlled to rotate to rotate the graphite coil, and then the cutter of the cutting mechanism is controlled to approach the rotating graphite coil, thereby cutting and segmenting the graphite coil. However, during the cutting process of this cutting device, the graphite coil will be pushed by the cutter, which will cause the cut end face to have a large inclination, resulting in an uneven cut end face, causing the graphite coil to become loose, affecting the subsequent cutting quality. Summary of the invention

[0004] Based on this, it is necessary to provide an efficient and stable cutting device for graphite coils to address the technical problem that the current cutting device will make the cut end surface of the graphite coil uneven and thus affect the subsequent cutting quality.

[0005] The above purpose is achieved through the following technical solutions: A highly efficient and stable cutting device for graphite coils comprises a supporting platform, on which a placement shaft is rotatably provided, the placement shaft being used to install the graphite coils, and a cutting machine is also provided on the supporting platform, on which a cutter is rotatably provided, the cutter being a circular plate-like structure, the plane where the cutter is located being perpendicular to the axis of the placement shaft, the cutter being able to slide in directions parallel to the axis of the placement shaft and in directions perpendicular to the axis of the placement shaft, respectively, so that the cutter cuts a plurality of cutting slits on the graphite coils; the cutting machine is also provided with a straightening plate, the straightening plate being arranged parallel to the plane where the cutter is located, the distance between the straightening plate and the cutter being adjustable, the straightening plate being able to move in the radial direction of the placement shaft so as to be inserted into the cutting slits.

[0006] Furthermore, a fixing plate is fixed on the cutting machine, a slide groove is provided on the fixing plate, the slide groove extends along the axial direction of the placement axis, a base is slidably provided in the slide groove, a mounting groove extending radially along the placement axis is provided in the base, and the straightening plate is slidably set in the mounting groove at one end away from the placement axis.

[0007] Furthermore, a telescopic electric cylinder is provided inside the installation groove, and a connecting block is provided at one end of the straightening plate away from the placement axis. The connecting block is slidably located in the installation groove and connected to the output end of the telescopic electric cylinder. The telescopic electric cylinder can drive the straightening plate to slide radially along the placement axis.

[0008] Furthermore, a guide head is integrally formed at one end of the straightening plate close to the placement axis. Along the axial direction of the placement axis, the thickness of the guide head is greater than the thickness of the straightening plate, and an inclined transition is formed between the guide head and the straightening plate.

[0009] Furthermore, there are two slide grooves, and two sliders are provided on the base. The sliders correspond to the slide grooves one by one and slide together. One of the slide grooves is provided with a scale line, and the scale line is used to observe the position of the slider in the slide groove.

[0010] Furthermore, a screw is fixedly provided on one side of the slider away from the base, and a first nut is threadedly connected to the screw. By rotating the first nut so that the first nut fits with the fixing plate, the position of the slider in the slide groove can be limited.

[0011] Furthermore, the support platform also includes a support base plate. Along the axial direction of the placement shaft, a control box is provided on one side of the support base plate, and a side plate is provided on the other side. The placement shaft is rotatably arranged between the control box and the side plate.

[0012] Furthermore, the control box is provided with a chuck, which is used to clamp and fix one end of the placement shaft. The side plate is provided with a bearing seat, and the other end of the placement shaft is rotatably set in the bearing seat.

[0013] Furthermore, the support base plate is also provided with a first horizontal slide rail extending axially along the placement axis, a sliding seat is slidably provided on the first horizontal slide rail, and a first driving motor is provided on the sliding seat. The first driving motor can drive the sliding seat to slide along the first horizontal slide rail.

[0014] Furthermore, the sliding seat is provided with a second horizontal slide rail extending radially along the placement axis, the cutting machine is fixedly provided with a chassis, the chassis is provided with a second drive motor, and the second drive motor can drive the chassis to slide along the second horizontal slide rail.

[0015] The beneficial effects of the present invention are: The efficient and stable graphite coil cutting device provided by the present invention has the following advantages: first, by providing a straightening plate, the straightening plate can be inserted into the cutting gap to support one side of the graphite coil being cut, thereby reducing the inclination of the cut end surface of the graphite coil, making the cut end surface smoother, and improving the cutting quality of the graphite coil. Moreover, the distance between the straightening plate and the cutter can be adjusted according to the cutting length of each section of the graphite coil, and has a certain degree of versatility.

[0016] Second, the upright plate and the inclined surface of the guiding head are in transitional connection. The inclined surface enables each section of the graphite coil to tilt a short distance towards the upright plate side. This distance will not cause the graphite coil to become scattered. At the same time, it increases the distance between the cutting end surface of the graphite coil and the cutting tool, reduces the frictional resistance between the two, and enables the cutting tool to smoothly cut the graphite coil.

[0021] In the present invention, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on" the second feature may be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under" and "beneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature has a lower horizontal height than the second feature.

[0022] As Figures 1 to 10As shown, an efficient and stable cutting device for graphite coils provided by an embodiment of the present invention comprises a supporting platform, on which a placement shaft 103 is rotatably provided, and the placement shaft 103 is used to install a graphite coil 300. A cutting machine 200 is also provided on the supporting platform, and a cutter 202 is rotatably provided on the cutting machine 200. The cutter 202 is a circular plate-like structure, and the plane where the cutter 202 is located is perpendicular to the axis of the placement shaft 103. The cutting machine 200 can slide in a direction parallel to the axis of the placement shaft 103 and in a direction perpendicular to the axis of the placement shaft 103, respectively, so that the cutter 202 cuts a plurality of cutting slits 301 on the graphite coil 300; a straightening plate 214 is also provided on the cutting machine 200, and the straightening plate 214 is arranged parallel to the plane where the cutter 202 is located, and the distance between the straightening plate 214 and the cutter 202 is adjustable, and the straightening plate 214 can move radially along the placement shaft 103 to be inserted into the cutting slit 301.

[0023] In this way, when in use, the cutting machine 200 is first controlled to make the cutter 202 cut the first cutting slit 301 on the graphite coil 300 to cut the first section of the graphite coil 300, and then the cutting machine 200 is controlled to make the cutter 202 cut the second cutting slit 301. At the same time, the straightening plate 214 is controlled to be inserted into the first cutting slit 301, so that the straightening plate 214 supports one side of the second section of the graphite coil 300 being cut. The support of the straightening plate 214 can reduce the inclination of the cut end face of the graphite coil 300, make the cut end face smoother, and improve the cutting quality of the graphite coil 300. Moreover, the distance between the straightening plate 214 and the cutter 202 can be adjusted according to the cutting length of each section of the graphite coil 300, which has a certain versatility.

[0024] like Figures 3 to 7 As shown, the cutting machine 200 is provided with a protective cover 203, and the protective cover 203 is used for dust prevention. The cutting machine 200 is fixedly provided with a fixing plate 210, and the fixing plate 210 is provided with a slide groove 212, and the slide groove 212 extends along the axial direction of the placement axis 103, and a base 213 is slidably provided in the slide groove 212, and a mounting groove extending radially along the placement axis 103 is provided in the base 213, and the end of the straightening plate 214 away from the placement axis 103 is slidably provided in the mounting groove. Specifically, the cutting machine 200 is provided with a stud, and the fixing plate 210 is provided with a connecting hole, and the stud passes through the connecting hole and is threadedly connected with a second nut 216, and the detachable connection between the fixing plate 210 and the cutting machine 200 is achieved by rotating the second nut 216. By making the base 213 slide along the slide groove 212 of the fixing plate 210 , the base 213 drives the straightening plate 214 to slide along the axial direction of the placement shaft 103 , thereby adjusting the distance between the straightening plate 214 and the cutter 202 .

[0025] Furthermore, a telescopic electric cylinder 215 is provided inside the installation slot, and a connecting block 2141 is provided at one end of the straightening plate 214 away from the placement axis 103. The connecting block 2141 is slidably located in the installation slot and connected to the output end of the telescopic electric cylinder 215. The telescopic electric cylinder 215 can drive the straightening plate 214 to slide along the radial direction of the placement axis 103. In this way, the straightening plate 214 can be controlled to enter the cutting slit 301 or exit from the cutting slit 301 through the telescopic electric cylinder 215.

[0026] like Figures 8 to 10 As shown, the end of the straightening plate 214 close to the placement shaft 103 is integrally formed with a guide head 2142. Along the axial direction of the placement shaft 103, the thickness of the guide head 2142 is greater than the thickness of the straightening plate 214, and there is an inclined transition between the guide head 2142 and the straightening plate 214. Figure 9 The cutter 202 cuts the graphite coil 300 from left to right, and each cut forms a section of the graphite coil 300. The setting of the inclined surface enables each section of the graphite coil 300 to be tilted toward the side of the straightening plate 214 by a small distance, and this distance will not cause the graphite coil 300 to be scattered. At the same time, the distance between the cut end surface of the graphite coil 300 and the cutter 202 is increased, and the friction resistance between the two is reduced, so that the cutter 202 can smoothly cut the graphite coil 300.

[0027] Furthermore, two slide grooves 212 are provided, and two sliders 2133 are provided on the base 213. The sliders 2133 correspond to the slide grooves 212 one by one and slide together, so that the base 213 can slide smoothly. A scale line 211 is provided on one of the slide grooves 212, and the scale line 211 is used to observe the position of the slider 2133 in the slide groove 212. In this way, the distance between the straightening plate 214 and the cutter 202 can be read through the scale, so as to facilitate the adjustment of the cutting length of each section of the graphite coil 300.

[0028] Furthermore, a screw rod 2131 is fixedly provided on one side of the slider 2133 away from the base 213, and a first nut 2132 is threadedly connected to the screw rod 2131. By rotating the first nut 2132 to fit the first nut 2132 with the fixing plate 210, the position of the slider 2133 in the slide groove 212 can be limited. This makes it easy to adjust the distance between the straightening plate 214 and the cutter 202, and the operation is convenient.

[0029] Furthermore, the support platform also includes a support base plate 102 , along the axial direction of the placement shaft 103 , a control box 100 is provided on one side of the support base plate 102 , and a side plate 104 is provided on the other side, and the placement shaft 103 is rotatably arranged between the control box 100 and the side plate 104 .

[0030] like Figure 2As shown, the control box 100 is provided with a chuck 1031, and the chuck 1031 is used to clamp and fix one end of the placement shaft 103. The side plate 104 is provided with a bearing seat 1041, and the other end of the placement shaft 103 is rotatably arranged in the bearing seat 1041. The control box 100 is provided with a third drive motor (not shown in the figure), and the third drive motor can control the rotation of the chuck 1031, thereby realizing the rotation of the placement shaft 103.

[0031] The support base plate 102 is also provided with a first horizontal slide rail 1021 extending axially along the placement axis 103, a slide seat 108 is slidably provided on the first horizontal slide rail 1021, and a first drive motor 109 is provided on the slide seat 108. The first drive motor 109 can drive the slide seat 108 to slide along the first horizontal slide rail 1021. In this way, the cutting machine 200 is realized to slide in a direction parallel to the axis of the placement axis 103.

[0032] The sliding seat 108 is provided with a second horizontal slide rail (not shown) extending radially along the placement axis 103, and the cutting machine 200 is fixed with a chassis 107, and the chassis 107 is provided with a second drive motor 106, and the second drive motor 106 can drive the chassis 107 to slide along the second horizontal slide rail. In this way, the cutting machine 200 is realized to slide in a direction perpendicular to the axis of the placement axis 103.

[0033] like Figure 6 As shown, the cutting machine 200 is provided with a cutting motor 201, the output end of the cutting motor 201 is provided with a first gear 2011, the cutter 202 is connected to the second gear 2012 in a transmission manner, and the first gear 2011 and the second gear 2012 are connected in a transmission manner through a transmission belt. A support rod 105 is also provided between the control box 100 and the side plate 104, and an operating box is slidably provided on the support rod 105, and the operating box is used to control the cutting motor 201, the first drive motor 109 and the second drive motor 106. An operating panel 101 is provided on the control box 100, and the operating panel 101 can control the third drive motor.

[0034] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows: When in use, the graphite coil 300 to be cut is mounted on the placement shaft 103. Then the third driving motor is controlled to make the placement shaft 103 drive the graphite coil 300 to rotate, and the distance between the straightening plate 214 and the cutter 202 is adjusted according to the cutting length of each section of the graphite coil 300. Then the cutting motor 201, the first driving motor 109 and the second driving motor 106 are controlled to make the cutter 202 cut a first cutting slit 301 on the graphite coil 300, and the first section of the graphite coil 300 is formed after cutting.

[0035] Then, the cutting machine 200 is controlled to move rightward, so that the cutter 202 cuts the second cutting slit 301 on the graphite coil 300. While cutting, the telescopic electric cylinder 215 is controlled to synchronously insert the straightening plate 214 into the first cutting slit 301. During the initial insertion, the guide head 2142 of the straightening plate 214 is closer to the graphite coil 300 than the end of the cutter 202, that is, the guide head 2142 of the straightening plate 214 protrudes from the end of the cutter 202, and the protruding length is set to a.

[0036] Since the cutter 202 squeezes the graphite coil 300 in the process of cutting the second graphite coil 300, the second graphite coil 300 expands to the left and right sides, and the straightening plate 214 can support the left side of the second graphite coil 300, reducing the tilt of the second graphite coil 300. The inclined surface between the guide head 2142 and the straightening plate 214 can make the second graphite coil 300 tilt toward the straightening plate 214 by a short distance, which will not make the second graphite coil 300 scattered, and at the same time increase the distance between the cut end surface of the second graphite coil 300 and the cutter 202, reduce the friction resistance between the two, and enable the cutter 202 to smoothly cut the graphite coil 300. As the straightening plate 214 and the cutter 202 move synchronously along the radial direction of the placement axis 103, the straightening plate 214 can always balance the extrusion force on the cutting area, so that the inner layer and the outer layer of the second section of the graphite coil 300 are not prone to excessive tilt, thereby making the cut end surface smoother and improving the cutting quality of the graphite coil 300.

[0037] When the graphite coil 300 is wound, the inner layers of the graphite coil 300 are more closely fitted, while the outer layers of the graphite coil 300 are loosely fitted, so the extrusion force exerted by the cutter 202 on the inner layer of the graphite coil 300 is large, and the inclination of the cutting area is large, while the extrusion force exerted on the outer layer of the graphite coil 300 is small, and the inclination of the cutting area is also small. The moving speed of the straightening plate 214 can be controlled by controlling the telescopic electric cylinder 215, so that after the straightening plate 214 and the cutter 202 enter the interior of the graphite coil 300, the protruding length of the guide head 2142 is greater than a, and the closer to the innermost layer of the graphite coil 300, the greater the protruding length of the guide head 2142. In this way, the length of the force arm of the straightening plate 214 can be shortened, so that the inclination of the inner and outer layers of the graphite coil 300 remains basically consistent.

[0038] After the second graphite coil 300 is cut, the straightening plate 214 and the cutter 202 stop moving. Then, the cutter 202 and the straightening plate 214 are reset, and a limit plate (not shown in the figure) is manually inserted into the first cutting slit 301. The limit plate can prevent the first graphite coil 300 and the second graphite coil 300 from affecting each other.

[0039] Finally, repeat the above steps multiple times to obtain multiple graphite coil materials 300.

[0040] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0041] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
