Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0031] This utility model provides a rolling cutting device and rolling cutting system, which can solve the technical problems of long time consumption and low work efficiency in the prior art of processing carbon strips by upper and lower punching.
[0032] See Figure 1 As shown in the figure, an embodiment of the present invention provides a rolling cutting device, which includes a table 1 and a rolling cutting mold 2. The table 1 is used to convey carbon cloth 3 to be rolled and cut. The rolling cutting mold 2 is rotatably mounted on the table 1. The rolling cutting mold 2 has a cylindrical base 21 and multiple cutting blades 22 distributed on the outer periphery of the cylindrical base 21. The cylindrical base 21 rotates to drive the multiple cutting blades 22 to roll and cut the carbon cloth 3. The shape of each cutting blade 22 is determined according to the shape of the carbon strip 4. The rolling cutting mold of the present invention is mounted on the table, and the carbon cloth conveyed on the table is rolled and cut by the rotational movement of the rolling cutting mold, realizing the cutting of carbon cloth on a plane, reducing the carbon strip processing time and improving the processing efficiency.
[0033] This invention provides a rolling cutting device, which includes a table and a rolling cutting mold. The table is used to convey carbon cloth to be rolled, and the rolling cutting mold is rotatably mounted on the table. The rolling cutting mold has a cylindrical base and multiple cutting blades distributed on the outer periphery of the cylindrical base. The rotation of the cylindrical base drives the multiple cutting blades to roll and cut the carbon cloth. This invention, with the rolling cutting mold mounted on the table, rolls and cuts the carbon cloth conveyed on the table through the rotational movement of the rolling cutting mold, achieving flat-plane cutting of carbon cloth, reducing carbon strip processing time, and improving processing efficiency.
[0034] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 and Figure 2As shown, multiple cutting blades 22 are evenly spaced along the circumference on the outer surface of the cylindrical substrate 21. During the carbon cloth 3 cutting process, the multiple cutting blades 22 on the cylindrical substrate 21 cut and compress the horizontally moving carbon cloth 3 at the lowest point, causing the rolled carbon cloth 3 to peel off and fall off according to a preset shape, preparing for subsequent carbon bonding and pressing. The shape of each cutting blade 22 corresponds to the shape of the desired carbon strip 4. In this invention, the cutting blade 22 is an arc shape of a preset width, and the rolled cutting yields an arc-shaped carbon strip 4 of a preset width. This invention improves the processing efficiency of carbon cloth by rolling the carbon cloth with multiple cutting blades evenly spaced on the outer surface of the cylindrical substrate to obtain carbon strips.
[0035] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 3 As shown, the cylindrical base 21 and the plurality of cutting blades 22 are integrally formed. The integrally formed rolling cutting device effectively simplifies the production steps, shortens the production cycle, and also shortens the forming cycle of the carbon strip 4. It is suitable for complex structures and has a high degree of automation.
[0036] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 and Figure 4 As shown, the rolling die 2 is further provided with a transmission part 23, which is disposed on the table 1 and connected to the cylindrical base 21. The transmission part 23 provides rotational power to the cylindrical base 21. In this invention, the transmission part 23 includes a transmission shaft that passes through the cylindrical base 21, driving the cylindrical base 21 to rotate and roll-cut the carbon cloth 3 to obtain the carbon strip 4. The transmission part 23 of this invention provides rotational power to the cylindrical base 21, improving the rolling efficiency.
[0037] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 and Figure 3 As shown, each of the cutting blades 22 has the same radial angle. In this invention, maintaining the same radial angle among multiple cutting blades 22 facilitates control over the shape of the processed carbon strip 4, thereby improving the accuracy of the rolling cutting device.
[0038] As an optional implementation, in one embodiment of the utility model, the included angle ranges from 25° to 45°, and the included angle of each cutting blade 22 in the radial direction is consistent, and the included angle ranges from 25° to 45°. The radial included angle is within the range of 25° to 45° to ensure that each cutting blade 22 forms a suitable cutting angle with the carbon cloth 3, and to ensure the stability of the rolling cutting device.
[0039] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 and Figure 2 As shown, a gap is provided between each of the two adjacent cutting blades 22. The width of the gap gradually decreases from the middle to both sides. In practical applications, the width of the gap is appropriately adjusted according to the processing accuracy of the rolling die 2. Let the width of the gap be W, where W≠0. The smaller the value of W, the higher the utilization rate of the carbon cloth 3, that is, the more carbon strips 4 can be cut from a unit length of carbon cloth 3. When the size of W is too small, it increases the difficulty of processing the cutting blade 22. In this utility model, the width W of the same gap is not equal in different positions. The width W of the gap gradually decreases from the middle to both sides, which facilitates processing and improves the utilization rate of the carbon cloth.
[0040] As an optional implementation, in one embodiment of the invention, the middle width of the gap is 0.5-1.5mm and the edge width is within 1.0mm, which facilitates processing while improving the utilization rate of the carbon cloth.
[0041] As an optional implementation, in one embodiment of the invention, the cutting surface of each of the cutting blades 22 is coated with silicon carbide abrasive. The silicon carbide abrasive can remove burrs, improve surface quality and smoothness, and enhance the quality of carbon fiber processing.
