Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to a double-head peeling equipment and a peeling method. Background Art

[0002] Aluminum boxes and other metal box products are usually cut by rotary cutting machines. Currently, there are some double-head rotary cutting machines on the market that can cut both ends of the aluminum box at the same time to improve cutting efficiency.

[0003] However, the rotary cutter uses a single cam structure to drive the inner cutter, which moves along a fixed path and cuts the product. Due to the strong single-point pressure of the inner cutter on the product, when cutting thin-walled products, it is easy to squeeze and pull the inner wall, causing the product to become wavy and deformed, resulting in poor cutting quality.

[0052] like Figure 1-Figure 7 As shown, this embodiment provides a double-head peeling device for cutting a box body to be cut, and is particularly suitable for precision cutting of metal boxes such as aluminum boxes. The double-head peeling device includes a peeling module 100, a fixing base 200, a plurality of guide shafts 300, a linear push component 400 and an external cutting module 500, wherein the fixing base 200 is fixedly mounted on the ground or a machine table, the plurality of guide shafts 300 are extended along a third direction and fixed to the fixing base 200, the peeling module 100 is slidably mounted on the plurality of guide shafts 300, the external cutting module 500 is fixed to the plurality of guide shafts 300, the linear push component 400 is mounted on the fixing base 200, and the output end of the linear push component 400 is connected to the peeling module 100 to drive the peeling module 100 to slide along the plurality of guide shafts 300 and approach or move away from the external cutting module 500 and the box body to be cut, the peeling module 100 is used to cut the box body to be cut from the inside, and the external cutting module 500 allows the box body to be cut to pass through and assists in fixing the box body to be cut. The third direction is the Z direction (horizontal direction) in the figure.

[0053] Further, such as Figure 2-Figure 6 As shown, the peeling module 100 includes an internal cutting tool 10, a peeling power assembly 20, and a peeling transmission assembly 30. The internal cutting tool 10 is provided with spikes 11 at two separated ends. The peeling power assembly 20 includes a first peeling drive 21 and a second peeling drive 22. The peeling transmission assembly 30 includes a first cam 31, a second cam 32, and a follower seat. The first cam 31 is connected to the output shaft of the first peeling drive 21, and the second cam 32 is connected to the output shaft of the second peeling drive 22. The internal cutting tool 10 is mounted on the follower seat. The first cam 31 directly or indirectly abuts the follower seat in a first direction. When the first peeling drive 21 drives the first cam 31 to rotate, the follower seat is driven to move in the first direction. The second cam 32 directly or indirectly abuts the follower seat in a second direction. When the second peeling drive 22 drives the second cam 32 to rotate, the follower seat is driven to move in the second direction. The first direction is perpendicular to the second direction. The first direction is the X direction (horizontal direction) in the figure, and the second direction is the Y direction (vertical direction) in the figure.

[0054] Specifically, the double-headed peeling device provided in this embodiment cuts the box body to be cut from the inside of the box body to be cut through the peeling module 100. On the one hand, the peeling power assembly 20 includes a first peeling drive member 21 and a second peeling drive member 22. The first peeling drive member 21 pushes the follower seat to move in the first direction through the first cam 31, and the second peeling drive member 22 pushes the follower seat to move in the second direction through the second cam 32. Under the drive of the peeling power assembly 20, the internal cutting tool 10 installed on the follower seat can freely translate in the plane where the first direction and the second direction are common. Therefore, the internal cutting tool 10 can walk along a variety of paths and cut the box body to be cut, greatly improving the flexibility of the tool path. On the other hand, the inner cutting tool 10 is provided with sharp thorns 11 at the two ends thereof. When cutting starts, the two sharp thorns 11 can be driven successively to pierce the side walls of the box body to be cut, thereby dividing the incision of the box body to be cut into two independent strip-shaped broken walls. When piercing, the sharp thorns 11 increase the single-point pressure on the box body to be cut, so that only a smaller force needs to be applied to pierce the box body to be cut, thereby reducing the pulling force on the box body to be cut. After piercing, when the inner cutting tool 10 cuts off the strip-shaped broken wall again, since the two strip-shaped broken walls have been separated from each other, the inner cutting tool 10 will not pull the box body to be cut and the strip-shaped broken wall on the other side, thereby not causing wave deformation at the incision, thereby improving the quality and accuracy of cutting.

[0055] For example, Figure 3 As shown, the two spikes 11 are centrally symmetrically distributed about the geometric center of the internal cutting tool 10. When cutting begins, the rotary cutting power assembly 20 drives the internal cutting tool 10 to move a predetermined distance in two opposite directions, preferably in the direction facing the spikes 11, so that the two spikes 11 protrude outward and pierce the box body to be cut, thereby forming two strip-shaped broken walls of the same length and shape. This simplifies the cutting path of the internal cutting tool 10, reduces the control difficulty, and improves the cutting accuracy.

[0056] For example, Figure 3 As shown, the internal cutting tool 10 also includes a tool body 12. The cross-section of the tool body 12 is a rectangular structure. The two spikes 11 are respectively arranged outside the two opposite corners of the tool body 12. The spikes 11 have a convex angle α set outward. The angle of the convex angle α is less than 90° and is an acute angle, so as to further increase the single-point pressure during puncture, reduce the pulling force on the box body to be cut, and improve the cutting accuracy.

[0057] Preferably, the convex angle α of the spike portion 11 is 70°.

[0058] For example, Figure 4-Figure 6 As shown, the peeling die set 100 further includes a mounting seat 101 and a mounting base 102, wherein the mounting seat 101 is fixed to the mounting base 102. The follower seat includes a first follower plate 33 and a second follower plate 34.

[0059] For the first follower plate 33, as Figure 4-Figure 6 As shown, the first follower plate 33 is slidably mounted on the mounting seat 101 along the first direction. A first push hole 331 is provided on the first follower plate 33. A first push block 35 is provided on the outer sleeve of the first cam 31. Specifically, a plurality of bearings are provided on the outer periphery of the first cam 31, which is rotatably connected to the first push block 35 via the bearings. The first push block 35 is embedded in and slidably mounted in the first push hole 331 along the second direction. When the first rotary cutting drive member 21 drives the first cam 31 to rotate, the first cam 31 drives the first push block 35 to translate in a vertical plane. Since the first push block 35 can slide in the first push hole 331 along the second direction, the first follower plate 33 will not translate in the second direction with the first push block 35. In the first direction, the first push block 35 abuts against the inner wall of the first push hole 331, and the first follower plate 33 can translate in the horizontal first direction with the first push block 35.

[0060] For the second follower plate 34, Figure 4-Figure 6 As shown, the internal cutting tool 10 is fixed to the second follower plate 34, and the second follower plate 34 is slidably provided on the first follower plate 33 along the second direction. A second push hole 341 is provided on the second follower plate 34, and a second push block 36 is provided on the outer sleeve of the second cam 32. Specifically, a plurality of bearings are provided on the outer periphery of the second cam 32, which are rotatably connected to the second push block 36 through the bearings. The second push block 36 is embedded in and slidably provided in the second push hole 341 along the first direction. An avoidance groove 332 for avoiding the second cam 32 and the second rotary cutting drive member 22 is provided on the first follower plate 33. When the second rotary cutting drive member 22 drives the second cam 32 to rotate, the second cam 32 drives the second push block 36 to translate in a vertical plane. Since the second push block 36 can slide in the second push hole 341 along the first direction, the second follower plate 34 will not translate along the first direction with the second push block 36. In the second direction, the second push block 36 abuts against the inner wall of the second push hole 341, and the second follower can translate along the vertical second direction with the second push block 36.

[0061] In summary, the first driving member, the first cam 31 and the first follower plate 33 control the horizontal movement of the internal cutting tool 10, and the second driving member, the second cam 32 and the second follower plate 34 control the vertical movement of the internal cutting tool 10. The two sets of driving structures operate independently of each other and cooperate with each other to construct any tool path for the internal cutting tool 10. Compared with the fixed tool path design of the cam drive, the flexibility is greatly improved.

[0062] For example, Figure 4-Figure 6As shown, the mounting base 101 is provided with at least two first guide blocks 103. The at least two first guide blocks 103 extend along the first direction and respectively abut against two sides of the first follower plate 33 along the second direction. In this embodiment, the mounting base 101 is provided with three first guide blocks 103. Two of the first guide blocks 103 are spaced apart along the first direction and are both located on the upper side of the first follower plate 33. The other first guide block 103 is longer and is located on the lower side of the first follower plate 33. The three first guide blocks 103 collectively provide guidance for the first guide blocks 103 to slide along the first direction.

[0063] For example, Figure 4-Figure 6 As shown, multiple first guide blocks 103 are each installed with a first limit block 105 extending in the same direction therewith, and the first limit block 105 extends to the side of the first follower plate 33 away from the mounting seat 101. The multiple first limit blocks 105, the multiple first guide blocks 103 and the main body of the mounting seat 101 together form a slide groove structure that can limit the first follower plate 33. The first follower plate 33 can slide in it while preventing the first follower plate 33 from falling off.

[0064] For example, Figure 4-Figure 6 As shown, two second guide blocks 104 are provided on the first follower plate 33 and are spaced apart from each other. The two second guide blocks 104 are both extended along the second direction and respectively abut against two sides of the second follower plate 34 along the first direction.

[0065] For example, Figure 4-Figure 6 As shown, the two second guide blocks 104 are each equipped with a second limit block 106 extending in the same direction therewith. The second limit block 106 extends to the side of the second follower plate 34 away from the first follower plate 33. The two second limit blocks 106, the two first guide blocks 103 and the body of the first follower plate 33 together form a slide groove structure that can limit the second follower plate 34. The second follower plate 34 can slide in it while preventing the second follower plate 34 from falling off.

[0066] For example, Figure 2 As shown, the peeling module 100 further includes a front cover 108 , which is locked to a side of the mounting base 102 facing the outer cutting die plate 502 to cover the peeling transmission assembly 30 .

[0067] For example, Figure 2-Figure 6As shown, the first peeling drive 21 includes a first peeling motor, a first reducer, and a first output shaft. The motor shaft of the first peeling motor is connected to the input end of the first reducer, and the output end of the first reducer is connected to the first output shaft. The first cam 31 is fixed to the first output shaft. The first reducer is fixed to the mounting base 102 via a bearing seat 107. The first output shaft is sequentially inserted through the bearing seat 107, the mounting base 102, and the mounting seat 101. Optionally, the first cam 31 is eccentrically locked to the end of the first output shaft by a screw, or the first cam 31 is eccentrically arranged and integrally formed at the end of the first output shaft.

[0068] For example, Figure 2-Figure 6 As shown, the second peeling drive 22 includes a second peeling motor, a second reducer, and a second output shaft. The motor shaft of the second peeling motor is connected to the input end of the second reducer, and the output end of the second reducer is connected to the second output shaft. The second cam 32 is fixed to the second output shaft. The second reducer is fixed to the mounting base 102 via a bearing seat 107. The second output shaft is sequentially inserted through the bearing seat 107, the mounting base 102, and the mounting seat 101. Optionally, the second cam 32 is eccentrically locked to the end of the second output shaft by a screw, or the second cam 32 is eccentrically arranged and integrally formed at the end of the second output shaft.

[0069] For example, Figure 2 and Figure 7 As shown, the external cutting module 500 includes an external cutting mounting plate 501 and an external cutting blade plate 502. The external cutting mounting plate 501 is fixedly mounted on multiple guide shafts 300, and the external cutting blade plate 502 is fixed to the external cutting mounting plate 501. The external cutting blade plate 502 is provided with a cutting hole 503 for the box body to be cut along the third direction. The rotary cutting module 100 also includes a stripper plate 40, which is connected to the follower seat via an elastic member 50, specifically to the second follower plate 34. The stripper plate 40 is provided with an avoidance hole, and the internal cutting tool 10 is inserted into the avoidance hole. When the elastic member 50 is in its natural state, the internal cutting tool 10 is flush with the avoidance hole at one end facing the external cutting module 500. In the process of the linear pushing component 400 pushing the rotary cutting module 100 toward the external cutting module 500, when the internal cutting tool 10 penetrates the inner hole of the box body to be cut, the stripping plate 40 abuts against the end of the box body to be cut, and the elastic member 50 is compressed; after the cutting is completed, when the internal cutting tool 10 moves in the opposite direction, the elastic member 50 extends and drives the stripping plate 40 to reset, and the stripping plate 40 can push the cut residual material away from the internal cutting tool 10 and fall off.

[0070] For example, Figure 2 and Figure 5As shown, the internal cutting tool 10 is connected to the second follower plate 34 at intervals through two positioning pins 13, and the stripping plate 40 is slidably arranged on the side of the second follower plate 34 close to the external cutting module 500 along the third direction through the guide shaft. The two ends of multiple elastic members 50 respectively abut or connect the second follower plate 34 and the stripping plate 40. The elastic members 50 can be elastic elements such as compression springs and rubber rods.

[0071] For example, Figure 2 As shown, a limiting pin 60 is installed on the side of the front cover 108 facing the external cutting module 500. When the linear pushing component 400 drives to move toward the external cutting module 500, the limiting pin 60 of the rotary cutting module 100 can abut the external cutting mounting plate 501 to limit the minimum distance between the rotary cutting module 100 and the external cutting module 500, thereby improving safety.

[0072] For example, Figure 1 As shown, the linear driving assembly 400 includes two linear drive members 410, which are symmetrically arranged on the left and right sides of the fixed base 200. The output ends of the two linear drive members 410 are both connected to the peeling module 100. During operation, the two linear drive members 410 extend and retract synchronously, thereby driving the peeling module 100 toward or away from the circumcision module 500 with a more stable output force.

[0073] For example, the linear drive member 410 may be a hydraulic cylinder, an electric push rod or other drive member.

[0074] For example, Figure 1 As shown, in the third direction, there are two rotary cutting modules 100, fixed seats 200, linear push components 400 and external cutting modules 500 symmetrically arranged, and the two internal cutting knives 10 of the two rotary cutting modules 100 are arranged facing each other. The two linear push components 400 can respectively drive the two rotary cutting modules 100 to move toward the external cutting module 500, and the two internal cutting knives can cut the two ends of the box to be cut at the same time, thereby improving the working efficiency.

[0075] like Figure 8 As shown, this embodiment also provides a peeling method, which is implemented based on the aforementioned double-head peeling device and includes the following steps:

[0076] The rotary cutting power assembly 20 drives the internal cutting tool 10 to move horizontally, so that one of the sharp thorns 11 pierces the first point of the box body to be cut;

[0077] The rotary cutting power assembly 20 drives the inner cutting tool 10 to move in another direction, so that the other sharp thorn portion 11 pierces the second point of the box body to be cut, so that the cut end of the box body to be cut forms two strip-shaped broken walls;
