Description

Technical Field

[0001] This utility model relates to a bimetallic sheet cutting and blanking device. Background Technology

[0002] Currently, a special strip is required for the production of bimetallic sheets. For example, Chinese patents CN207781487U and CN207752944U disclose strips for producing bimetallic sheets. These strips include a long connecting strip and multiple bimetallic sheets sequentially connected to it. The connecting strip also has positioning holes. During production, contact points are welded onto the bimetallic sheets in the strip, and the sheets are stamped. Then, the bimetallic sheets are stamped and cut from the connecting strip to obtain the finished product. However, some existing cutting mechanisms fail to position and clamp the strip when cutting the bimetallic sheets from the connecting strip, resulting in poor cut quality, such as rough and uneven cuts, which affects the quality of the bimetallic sheet. Utility Model Content

The stepping feeding mechanism transports the strip in the main channel forward by a certain step length. Then, the driving mechanism drives the slide to slide downward, thereby driving the upper cutting die and the positioning and clamping die to move downward together. After the positioning and clamping die descends a certain distance, the clamping part will press against the connecting belt on the strip in the main channel, thereby clamping and fixing the strip. The positioning pin will be inserted into the positioning hole on the connecting belt to position the strip. Then, the driving mechanism will continue to drive the slide to slide downward. At this time, the upper cutting die will continue to move downward while the positioning and clamping die will not move downward.

[0051] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0052] like Figures 1-7 As shown, a bimetallic sheet cutting and feeding device includes a frame 1, a mounting base 2, a stepping feeding mechanism 3, and a bimetallic sheet cutting mechanism;

[0053] The mounting base 2 is connected to the frame 1, and the mounting base 2 is provided with a main channel 5 through which the feeding belt 4 passes;

[0054] The stepping feeding mechanism 3 is used to intermittently convey the material belt 4 in the main channel 5 forward;

[0055] The double-piece cutting mechanism is used to position and press the connecting strip 6 on the material strip 4 in the main channel 5 and cut off the bimetallic strip 7 on the material strip 4;

[0056] The dual-piece cutting mechanism includes a slide block 8, a positioning and clamping mold 9, an upper cutting mold 10, a lower cutting mold 11, and a driving mechanism 12.

[0057] The cutting die 11 is installed in the mounting base 2 and located below the connecting belt 6 on the material belt 4 in the main channel 5;

[0058] The slide block 8 is slidably disposed in the vertical direction;

[0059] The upper cutting die 10 is connected to the slide block 8, and the upper cutting die 10 is provided with a cutting blade 13;

[0060] The positioning and pressing mold 9 is slidably connected to the slide block 8 in the up and down direction. The lower end of the positioning and pressing mold 9 is provided with a pressing part 14 for pressing the connecting strip 6 on the material strip 4 and a positioning pin part 16 for inserting into the positioning hole 15 on the connecting strip 6.

[0061] The drive mechanism 12 is connected to the slide block 8 and is used to drive the slide block 8 to slide downward, thereby driving the upper cutting die 10 and the positioning and pressing die 9 to move downward so that the pressing part 14 presses the connecting strip 6 on the material strip 4 and the positioning pin part 16 is inserted into the positioning hole 15 on the connecting strip 6. The drive mechanism 12 is also used to continue to drive the slide block 8 to slide downward after the pressing part 14 presses the connecting strip 6, thereby driving the upper cutting die 10 to move downward so that the cutting part 13 cooperates with the lower cutting die 11 to cut the bimetallic sheet 7.

[0062] Specifically, the material strip 4 has the existing structure, including a connecting strip 6 and multiple bimetallic strips 7 sequentially connected to the connecting strip 6. The connecting strip 6 also has multiple positioning holes 15 arranged sequentially. First, the material strip 4 passes through the main channel 5 on the mounting base 2. The stepping feeding mechanism 3 transports the material strip 4 in the main channel 5 forward by a certain step length. Then, the driving mechanism 12 drives the slide block 8 to slide downward, thereby driving the upper cutting die 10 and the positioning and pressing die 9 to move downward together. After the positioning and pressing die 9 descends a certain distance, the pressing part 14 presses the connecting strip 6 on the material strip 4 in the main channel 5, thereby pressing and fixing the material strip 4. The positioning pin part 16 is inserted into the positioning hole 15 on the connecting strip 6 to position the material strip 4. Then, the drive mechanism 12 continues to drive the slide block 8 to slide downwards. At this time, the upper cutting die 10 continues to move downwards while the positioning and clamping die 9 does not move downwards. Then, the cutting blade 13 on the upper cutting die 10 cooperates with the lower cutting die 11 to cut off the bimetallic sheet 7. During the cutting process, the strip 4 is positioned and clamped, which improves the quality of the cut and avoids the problem of rough and uneven cuts, thereby improving the quality of the cut bimetallic sheet 7.

[0063] More specifically, after the cutting is completed, the drive mechanism 12 drives the slide 8 to slide upward, thereby moving the upper cutting die 10 and the positioning clamping die 9 upward so that the clamping part 14 releases the connecting strip 6 and the positioning pin part 16 exits the positioning hole 15. Then, the stepping feeding mechanism 3 again conveys the material strip 4 in the main channel 5 forward by a certain step length. Then, the drive mechanism 12 drives the slide 8 downward again to repeat the above process so as to cut the bimetallic sheet 7 again. In this process, the stepping feeding mechanism 3 conveys the material strip 4 forward by an equal step length each time.

[0064] like Figures 2-6 As shown, the mounting base 2 may include a base 17 and a limiting plate 18;

[0065] The base 17 is connected to the frame 1, the limiting plate 18 is connected to the base 17, the main channel 5 is located between the base 17 and the limiting plate 18, and the limiting plate 18 is provided with a protrusion 19 extending above the connecting strip 6 on the material strip 4 in the main channel 5; specifically, the protrusion 19 extending above the connecting strip 6 can restrict the entire material strip 4 in the main channel 5; wherein, the cutting die 11 is installed in the base 17.

[0066] like Figures 2-6 As shown, the protrusion 19 is provided with a notch 20 corresponding to the pressing part 14. When the positioning pressing mold 9 moves downward, the pressing part 14 is used to extend into the corresponding notch 20 and press the connecting strip 6 on the material strip 4 in the main channel 5.

[0067] The positioning pin 16 is provided on the lower end of the clamping part 14;

[0068] The base 17 is provided with a pin hole 21 corresponding to the positioning pin 16. The pin hole 21 is aligned with the corresponding positioning pin 16. The positioning pin 16 is inserted into the positioning hole 15 on the connecting band 6 and then inserted into the corresponding pin hole 21. In this embodiment, the lower end of the positioning pin 16 is a tapered structure.

[0069] like Figures 2-4 As shown, the slide block 8 may include a base 22 and a cover plate 23. The cover plate 23 is connected to the base 22. An installation space is provided between the cover plate 23 and the base 22. The upper cutting die 10 and the positioning and clamping die 9 are both installed in the installation space.

[0070] The upper cutting die 10 is provided with a first protrusion 24 that protrudes to the side. The upper end of the cover plate 23 abuts against the lower end face of the first protrusion 24, and the upper end face of the upper cutting die 10 abuts against the base 22, thereby fixing the upper cutting die 10 in the installation space.

[0071] The base 22 is provided with a limiting groove 25. The positioning and clamping mold 9 is provided with a second protrusion 26 that protrudes to the side and cooperates with the limiting groove 25. When the positioning and clamping mold 9 slides downward relative to the base 22, the second protrusion 26 abuts against the bottom wall of the limiting groove 25. When the positioning and clamping mold 9 slides upward relative to the base 22, the second protrusion 26 abuts against the top wall of the limiting groove 25, thereby limiting the sliding stroke of the positioning and clamping mold 9 in the slide block 8.

[0072] like Figure 3 , 4 As shown, the bimetallic sheet cutting and blanking device may further include a spring 27, which is installed between the positioning and clamping mold 9 and the seat 22. The upper end of the spring 27 abuts against the seat 22, and the lower end of the spring 27 abuts against the positioning and clamping mold 9. The spring 27 is used to drive the positioning and clamping mold 9 to slide downward relative to the seat 22. In this embodiment, the clamping force of the clamping part 14 pressing against the connecting strip 6 can be provided by the elastic force of the spring 27. In some embodiments, the spring 27 may not be provided, in which case the clamping force of the clamping part 14 pressing against the connecting strip 6 can be provided by the gravity of the positioning and clamping mold 9.

[0073] Specifically, a vertical plate 28 is connected to the base 17, and a top plate 29 is connected to the upper end of the vertical plate 28. The seat body 22 in the slide 8 is slidably connected to the vertical plate 28 in the vertical direction via a guide rail. The driving mechanism 12 is a driving cylinder, the cylinder body of the driving cylinder is connected to the top plate 29, and the piston rod of the driving cylinder is connected to the seat body 22 in the slide 8.

[0074] like Figure 1 , 3 As shown in Figures 5, 6, and 7, the bimetallic sheet cutting and feeding device may further include a material collection drawer 30;

[0075] The frame 1 is provided with a material collection space for placing the material collection drawer 30;

[0076] The base 17 is provided with an upper feeding channel 31 through which the cut bimetallic sheet 7 passes;

[0077] The frame 1 is provided with a dropping channel 32, the upper end of which is connected to the lower end of the upper dropping channel 31, and the lower end of the dropping channel 32 is connected to the collection drawer 30. Specifically, the cut bimetallic sheet 7 will pass through the upper dropping channel 31 and the dropping channel 32 and fall into the collection drawer 30.

[0078] like Figure 1 , 5 As shown in Figures 6 and 7, the stepping feeding mechanism 3 may include a support plate 33, a horizontal cylinder 34, a horizontal shifting seat 35, a vertical cylinder 36, a connecting seat 37, and an insert rod 38.

[0079] The support plate 33 is connected to the frame 1, the transverse cylinder 34 is connected to the support plate 33, and the transverse shift seat 35 is connected to the transverse cylinder 34. The transverse cylinder 34 is used to drive the transverse shift seat 35 to move along the length direction of the material belt 4.

[0080] The vertical cylinder 36 is connected to the horizontal moving seat 35, the connecting seat 37 is connected to the vertical cylinder 36, and the insert rod 38 is connected to the connecting seat 37. The vertical cylinder 36 drives the connecting seat 37 to move downward, thereby driving the insert rod 38 to move downward into the positioning hole 15 in the connecting strip 6 of the material belt 4 inserted into the main channel 5. In this embodiment, the specific process of the stepping feeding mechanism 3 intermittently conveying the material belt 4 in the main channel 5 forward is as follows: First, the vertical cylinder 36 drives the connecting seat 37 to move downward, thereby driving the insert rod 38 to move downward so that the lower end of the insert rod 38 is inserted into the positioning hole 15 in the connecting strip 6 of the material belt 4. Then, the horizontal cylinder 34 drives the horizontal moving seat 35 to move forward, thereby driving the vertical cylinder 36, the connecting seat 37, the insert rod 38, and the material belt 4 to move forward together. Then, the drive mechanism 12 drives the slide block 8 to slide downwards, thereby causing the upper cutting die 10 and the positioning and clamping die 9 to move downwards together. After the positioning and clamping die 9 descends a certain distance, the clamping part 14 will press the connecting strip 6 on the material strip 4 in the main channel 5, thereby pressing and fixing the material strip 4. The positioning pin part 16 will be inserted into the positioning hole 15 on the connecting strip 6 to position the material strip 4. Then, the drive mechanism 12 will continue to drive the slide block 8 to slide downwards. At this time, the upper cutting die 10 will continue to move downwards while the positioning and clamping die 9 will not move downwards. Then, the cutting part 13 on the upper cutting die 10 will cooperate with the lower cutting die 11 to cut off the bimetallic sheet 7. While the clamping part 14 clamps the connecting strip 6, the vertical cylinder 36 drives the connecting seat 37 to move upward, thereby moving the insert rod 38 upward so that the lower end of the insert rod 38 exits the positioning hole 15. Then, the horizontal cylinder 34 drives the transverse seat 35 to move backward, thereby moving the vertical cylinder 36, the connecting seat 37, and the insert rod 38 backward together to reset. After resetting, the vertical cylinder 36 drives the connecting seat 37 to move downward, thereby moving the insert rod 38 downward so that the lower end of the insert rod 38 inserts into the positioning hole 15 in the connecting strip 6 on the material belt 4. Repeating the above steps can intermittently convey the material belt 4 in the main channel 5 forward. In this embodiment, both the horizontal cylinder 34 and the vertical cylinder 36 are slide cylinders.

[0081] like Figure 5 , 6 As shown, the base 17 is provided with a lower waist-shaped groove 39, and the limiting plate 18 is provided with an upper waist-shaped groove 40. Both the upper waist-shaped groove 40 and the lower waist-shaped groove 39 extend along the length direction of the material strip 4. The lower end of the insertion rod 38 is used to pass through the upper waist-shaped groove 40 and then insert into the positioning hole 15 and then into the lower waist-shaped groove 39.

[0082] like Figure 1 , 7 As shown in Figure 8, the bimetallic strip cutting and feeding device may further include a waste cutting mechanism 41. The waste material of the connecting strip formed after the bimetallic strip 7 is cut off from the connecting strip 6 extends into the waste cutting mechanism 41. The waste cutting mechanism 41 is used to cut and cut the waste material of the connecting strip.

[0083] like Figure 1 , 7 As shown in Figures 8 and 9, the waste cutting mechanism 41 may include a cutting seat 42, an upper cutting block 43, a lower cutting block 44, and a cutting cylinder 45.

[0084] The cutting seat 42 is connected to the frame 1;

[0085] The lower cutting block 44 is installed in the cutting seat 42, and the lower cutting block 44 is provided with a sliding channel 46;

[0086] The lower end of the upper cutting block 43 is slidably fitted in the sliding channel 46. The lower end of the upper cutting block 43 is provided with a cutting groove 47 with the opening facing downward. The waste material of the connecting belt passes through the upper part of the lower cutting block 44 and through the cutting groove 47.

[0087] The cutting cylinder 45 is connected to the cutting seat 42. The cutting cylinder 45 is connected to the upper cutting block 43 and is used to drive the upper cutting block 43 to move up and down so that the upper cutting block 43 cooperates with the lower cutting block 44 to cut the waste material of the connecting strip.

[0088] The cutting seat 42 is provided with a connecting channel 48 located below the sliding channel 46;

[0089] The frame 1 is provided with a discharge channel 49 located below the connection channel 48;

[0090] The frame 1 is also connected to a discharge pipe 50 located below the discharge channel 49; specifically, after the connecting strip waste is cut, it passes downwards through the sliding channel 46, the connecting channel 48, the discharge channel 49 and the discharge pipe 50 in sequence and is then collected; wherein, the cutting seat 42 is also provided with a guide channel 51, the connecting strip waste passes through the guide channel 51 and then passes over the lower cutting block 44 and through the cutting groove 47.

[0091] In summary, the strip 4 includes a connecting strip 6 and multiple bimetallic strips 7 sequentially connected to the connecting strip 6. The connecting strip 6 also has multiple positioning holes 15 arranged sequentially. First, the strip 4 is passed through the main channel 5 on the mounting base 2. The stepping feeding mechanism 3 transports the strip 4 in the main channel 5 forward by a certain step length. Then, the driving mechanism 12 drives the slide block 8 to slide downward, thereby driving the upper cutting die 10 and the positioning and pressing die 9 to move downward together. After the positioning and pressing die 9 descends a certain distance, the pressing part 14 presses the connecting strip 6 on the strip 4 in the main channel 5, thereby pressing and fixing the strip 4. The positioning pin part 16 is inserted into the positioning hole 15 on the connecting strip 6 to position the strip 4. Then, the drive mechanism 12 continues to drive the slide block 8 to slide downwards. At this time, the upper cutting die 10 continues to move downwards while the positioning and clamping die 9 does not move downwards. Then, the cutting blade 13 on the upper cutting die 10 cooperates with the lower cutting die 11 to cut off the bimetallic sheet 7. During the cutting process, the strip 4 is positioned and clamped, which improves the quality of the cut and avoids the problem of rough and uneven cuts, thereby improving the quality of the cut bimetallic sheet 7.

[0092] After the cutting is completed, the drive mechanism 12 will drive the slide 8 to slide upward, thereby driving the upper cutting die 10 and the positioning clamping die 9 to move upward so that the clamping part 14 releases the connecting strip 6 and the positioning pin part 16 exits the positioning hole 15. Then the stepping feeding mechanism 3 will again convey the material strip 4 in the main channel 5 forward by a certain step length. Then the drive mechanism 12 will drive the slide 8 to slide downward again to repeat the above process so as to cut the bimetallic sheet 7 again.

[0093] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
