[0024] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 4 , Figure 1 which is a schematic structural diagram of a pattern roller milling machine provided by the present invention; Figure 2 is Figure 1 the top view of Figure 3 which is a flowchart of a method for manufacturing a pattern roller provided by the present invention; Figure 4 is Figure 3 the specific flowchart of step S2 in

[0026] A pattern roller milling machine provided by the present invention, as shown in Figure 1 and Figure 2 , the pattern roller milling machine mainly includes: a base 1, a support frame 2, a lifting mechanism 3 and a milling mechanism 4.

[0027] The support frame 2 is connected to the base 1 and is located above the base 1. The two ends thereof are provided with thimbles for fixing the roller 01 to be processed, so that the roller 01 to be processed is placed horizontally; in addition, the support frame 2 can also drive the roller 01 to be processed to rotate. The structure and functional principle of the part for driving the roller 01 to be processed to rotate can refer to the corresponding part of the roller shaft processing machine tool in the prior art, which will not be elaborated here.

[0028] The lifting mechanism 3 is arranged on the base 1. The lifting mechanism 3 is located below the support frame 2 and is used to control the lifting of the milling mechanism 4. At the same time, the milling mechanism 4 is also located below the support frame 2, so as to facilitate the milling mechanism 4 to abut against the bottom surface of the roller 01 to be processed or to move the milling mechanism 4 downward to disengage from the roller 01 to be processed.

[0029] The milling mechanism 4 includes a milling drive part 42 and a plurality of milling cutters 41. Among them, all the milling cutters 41 are connected to the milling drive part 42. The milling drive part 42 provides power for the milling cutters 41 so that the milling cutters 41 can mill out pattern grooves on the bottom surface of the roller 01 to be processed. Moreover, the milling drive part 42 is arranged on the lifting mechanism 3, so that the milling cutters 41 can move up and down with the lifting mechanism 3.

[0030] Preferably, the relevant dimensions of the pattern grooves are set as follows: groove depth 3.8(+0 to 0.3) mm, upper opening width 8(+0 to 0.2) mm, groove length 28.5(+0 to 1.0) mm, groove pitch 42 ± 0.5 mm, groove wall included angle 60° to 115°; in addition, the relevant dimensions of the milling cutter 41 are set as follows: inclination angle 75° (corresponding to the 75° groove wall included angle), cutter width 10 mm, cutter thickness 3 mm, height 8 mm.

[0031] In the first embodiment, as Figure 2 shown, the lifting mechanism 3 includes: a vertical guide rail 31, a lifting table 32, and a lifting drive part 33. Among them, the vertical guide rail 31 is arranged on the base 1 and extends vertically. Preferably, two vertical guide rails 31 are provided, and the two vertical guide rails 31 are respectively arranged at both ends of the lifting table 32 in the axial direction of the roller 01 to be processed. Preferably, the above-mentioned vertical guide rail 31 is specifically a guide shaft in the shape of a quadrangular prism; the lifting table 32 is in a plate shape, and both ends thereof are slidably connected to the vertical guide rail 31. Preferably, both ends of the lifting table 42 have guide holes for the above-mentioned guide shaft to pass through, so that the lifting table 32 can stably move along the above-mentioned guide shaft; the lifting drive part 33 is arranged above the base 1, and is connected to the lifting table 32 and used to drive the lifting table 32 to move up and down vertically.

[0032] In the second embodiment, as Figure 1 shown, the above-mentioned lifting drive part 33 includes: a plurality of ball screws 331, a gear-rack transmission (not shown in the figure), and a lifting drive motor (not shown in the figure). Among them, the bottom of the screw in any one of the ball screws 331 is connected to the gear in the gear-rack transmission, and the nut in the ball screw 331 is fixedly connected to the lifting table 32. Preferably, four ball screws 331 are provided, and the four ball screws 331 are respectively arranged at the four corner positions of the lifting table 32; the gear-rack transmission has a gear and a rack. Preferably, two of the above-mentioned gears are provided and respectively cooperate with the screws in the above-mentioned two ball screws 331; the output end of the lifting drive motor is connected to the rack in the gear-rack transmission to drive the rack to move along the axial direction of the roller 01 to be processed.

[0033] In order to further ensure the simple appearance of this pattern roller milling machine, the above-mentioned gear-rack transmission is arranged in the box body 332, and at the same time, dust is prevented from falling on the tooth surfaces of both the gear and the rack, and the output end of the lifting drive motor and the ball screw 331 penetrate through the above-mentioned box body 332.

[0034] In the third embodiment, as Figure 2As shown, all the milling cutters 41 are evenly divided into a first bevel cutting group and a second bevel cutting group according to the quantity. Among them, all the milling cutters 41 in the first bevel cutting group are arranged at a preset angle inclined towards the positive direction with respect to the axial direction of the roller 01 to be processed, while all the milling cutters 41 in the second bevel cutting group are arranged at a preset angle inclined towards the negative direction with respect to the axial direction of the roller 01 to be processed. Preferably, the above preset angle is 45°.

[0035] In addition, all the milling cutters 41 in the first bevel cutting group are arranged on the positive side of the axial direction of the roller 01 to be processed (that is, Figure 2 the upper side in the perspective), while all the milling cutters 41 in the second bevel cutting group are arranged on the negative side of the axial direction of the roller 01 to be processed (that is, Figure 2 the lower side in the perspective); the distance between any two adjacent milling cutters 41 in the first bevel cutting group is equal to the distance between any two adjacent milling cutters 41 in the second bevel cutting group, and all the milling cutters 41 in the first bevel cutting group and all the milling cutters 41 in the second bevel cutting group are arranged alternately, so that the milling cutters 41 in the first bevel cutting group and the milling cutters 41 in the second bevel cutting group are arranged successively along the axial direction of the roller 01 to be processed.

[0036] Preferably, 26 milling cutters 41 are provided in total, and both the first bevel cutting group and the second bevel cutting group have 13 milling cutters 41. Taking the axial direction of the roller 01 to be processed as a reference, the distance between any two adjacent milling cutters 41 in the first bevel cutting group and the second bevel cutting group is 126 mm.

[0037] In the fourth embodiment, as Figure 1 and Figure 2 shown, the milling drive part 42 includes: a first transmission gearbox 421, a first motor 422, a second transmission gearbox 423 and a second motor 424. Among them, the output end of the first transmission gearbox 421 is connected to all the milling cutters 41 in the first bevel cutting group, and the output end of the first motor 422 is connected to the first transmission gearbox 421 to control all the milling cutters 41 in the first bevel cutting group to start and stop simultaneously; similarly, the output end of the second transmission gearbox 423 is connected to all the milling cutters 41 in the second bevel cutting group, and the output end of the second motor 424 is connected to the second transmission gearbox 423 to control all the milling cutters 41 in the second bevel cutting group to start and stop simultaneously.

[0038] It should be noted that the structures of the above first motor 422 and second motor 424 are the same; and the structures of the first transmission gearbox 421 and the second transmission gearbox 423 are symmetrical. Specifically, both the first transmission gearbox 421 and the second transmission gearbox 423 include a rotating shaft and a transmission gear. Among them, the rotating shaft is sleeved with the milling cutter 41 so that all the milling cutters 41 on the rotating shaft can rotate synchronously with the rotating shaft, and the gear is sleeved on the rotating shaft, which rotates synchronously with the rotating shaft, and the gear is connected to the output end of the first motor 422 (or the second motor 424).

[0039] In the fifth embodiment, if the distance between two adjacent milling cutters 41 is too large or the length of the roller 01 to be processed is too long, the production efficiency of the pattern roller will be reduced. In order to machine relatively dense pattern grooves on the entire bottom surface of the roller 01 to be processed, as Figure 1 shown, axial translation mechanisms 5 are connected to the bottoms of both ends of the support frame 2, and the two axial translation mechanisms 5 are both arranged on the base 1.

[0040] Any one of the axial translation mechanisms 5 mainly includes a support column 51 and a jack (not shown in the figure). Among them, the bottom of the support column 51 is fixed to the base 1, and the top of the support column 51 is slidably connected to the support frame 2 along the axial direction of the roller 01 to be processed, that is, a slide rail mechanism is provided at the top of the support column 51 and the bottoms of both ends of the support frame 2; one end of the jack is fixed to the bottom of the support frame 2 through a mounting seat 52, and the other end of the jack is connected to the top of the support column 51, so that the support frame 2 moves axially relative to the support column 51 along the roller 01 to be processed through the jack.

[0041] A method for manufacturing a pattern roller provided by the present invention is applicable to the pattern roller milling machine as described above, as Figure 3 shown, the method for manufacturing a pattern roller includes:

[0042] Step S1: Uniformly set a plurality of circumferential processing positions along the circumference of the roller 01 to be processed. When rolling the steel plate with the pattern roller, it is necessary to ensure that the pattern grooves on the circumference of the pattern roller are evenly distributed. Therefore, a plurality of circumferential processing positions are uniformly set along the circumference of the roller 01 to be processed. Among them, the number of the above circumferential processing positions should be specifically determined according to the actual situation such as the diameter of the roller 01 to be processed. Preferably, the diameter Φ of the roller 01 to be processed is 570 ± 5 mm, and the radial length is 1650 mm. 43 circumferential processing positions are set with these dimensional parameters.

[0043] Step S2: Start the lifting mechanism 3 and the milling mechanism 4 to mill one circumferential processing position of the roller 01 to be processed. Specifically, when the roller 01 to be processed has not been milled, the lifting mechanism 3 and the milling mechanism 4 are located below the roller 01 to be processed (i.e., the initial position), and the bottom surface of the roller 01 to be processed (i.e., the circumferential processing position) is directly above the milling cutter 41. When processing, start the lifting mechanism 3 and the milling mechanism 4 to move the milling cutter 41 upward and mill a pattern groove at the circumferential processing position; after the processing is completed, the lifting mechanism 3 drives the milling mechanism 4 to move downward and return to the above initial position.

[0044] Step S3: Determine whether the milling process for all circumferential machining positions is completed. If not, proceed to Step S4, that is, rotate the roller 01 to be machined by the support frame 2 so that the next circumferential machining position that has not been milled faces downward and is aligned with the milling cutter 41, and then return to Step S2, and loop until the milling process for all circumferential machining positions is completed; otherwise, proceed to Step S5, that is, turn off the lifting mechanism 3 and the milling mechanism 4.

[0045] For the above-mentioned third and fifth embodiments, in order to machine the pattern grooves that are in the same direction and spaced 42 mm apart, as Figure 4 shown, Step S2 specifically includes:

[0046] Step S21: Start the lifting mechanism 3 and the milling mechanism 4 to perform the first milling on the roller 01 to be machined, so that all the milling cutters 41 perform milling on the circumferential machining positions of the roller 01 to be machined.

[0047] Step S22: Move one-third of the distance between two adjacent milling cutters 41 in the first bevel cutting group (i.e., 42 mm) in the positive axial direction through the axial translation mechanism 5, start the lifting mechanism 3 and the milling mechanism 4 to perform the second milling on the roller 01 to be machined, so that 25 of the milling cutters 41 perform milling on the circumferential machining positions of the roller 01 to be machined, while the other milling cutter 41 located at the edge will not contact the roller 01 to be machined.

[0048] Step S23: Move two-thirds of the distance between two adjacent milling cutters 41 in the first bevel cutting group (i.e., 84 mm) in the reverse axial direction through the axial translation mechanism 5, start the lifting mechanism 3 and the milling mechanism 4 to perform the third milling on the roller 01 to be machined, so that 25 of the milling cutters 41 perform milling on the circumferential machining positions of the roller 01 to be machined, while the other milling cutter 41 located at the other edge will not contact the roller 01 to be machined.

[0049] It should be noted that in the description of the present invention, the orientation or positional relationship indicated by "axial", "circumferential", "bottom", "positive direction", and "reverse direction" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than limiting that the indicated elements or parts must have a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0050] The above has introduced in detail the pattern roll milling machine and the pattern roll manufacturing method provided by the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
