Abstract
Description
Technical Field
[0001] The utility model relates to the field of packaging machinery, in particular to a cup-linking punching and shearing device. Background Art
[0002] Common multi-cup products, such as yogurt, consist of multiple cups of yogurt combined together when sold, connected by the sheet material of the cup body. Each cup of yogurt is separated by a distinct indentation and notch, which are created by punching and shearing during the multi-cup product production process. The punching and shearing action is performed by a multi-cup punching and shearing device. In the prior art, the multi-cup punching and shearing device is equipped with a die-cutting component and a die. The die-cutting component is equipped with a press cutter, and the die is equipped with a cutting groove corresponding to the press cutter. During punching and shearing, the sheet material that will become the cup body is positioned between the die-cutting component and the die. Once the die-cutting component and the die are closed, both sides of the sheet material are adjacent to the press cutter and the cutting groove. When the press cutter pushes the sheet material toward the cutting groove, the sheet material deforms into the cutting groove. This deformation of the sheet material during punching and shearing prevents sufficient shear force from being generated, making it impossible to form an indentation or cut the sheet material. Utility Model Content
[0003] The utility model provides a cup-jointed punching and shearing device, which can solve the problem that sheets at the joints of cup-jointed products are deformed during punching and shearing, resulting in failure to form indentations or cut off the sheets.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cup-linking punching and shearing device, comprising a die-cutting assembly and a die, the die-cutting assembly performing an opening and closing movement relative to the die, the die being provided with a supporting surface abutting and supporting the connection between two adjacent cup-linking arms, the die-cutting assembly being provided with a first cutter for pressing and cutting the connection between the cup-linking arms, the first cutter being provided with a first sliding surface and a first extrusion surface, the first extrusion surface intersecting with the first sliding surface forming a first blade, the first sliding surface being parallel to the opening and closing direction of the die-cutting assembly, the supporting surface being provided with a cutting groove and a second cutter protruding toward one side of the die-cutting assembly, the second cutter being provided with a second sliding surface and a second extrusion surface, the second extrusion surface intersecting with the second sliding surface forming a second blade, the first sliding surface and the second sliding surface forming a shearing fit, the first extrusion surface and the second extrusion surface being staggered, the cutting groove being provided with a third sliding surface, the second sliding surface and the third sliding surface being located in the same plane.
[0005] Using the aforementioned technical solution, the die-cutting assembly opens and closes relative to the die, allowing the first cutter located within the die-cutting assembly to approach the die during punching and shearing. The die is provided with a support surface for stably supporting the lower surface of the cup-coupling connection during the punching and shearing process. The first sliding surface is parallel to the opening and closing direction of the die-cutting assembly, ensuring that the first cutter descends smoothly along a predetermined trajectory without deviation when the die-cutting assembly presses downward. The second sliding surface shears against the first sliding surface, enabling the first and second cutters to act parallel to each other on the upper and lower surfaces of the cup-coupling connection during the punching and shearing process. During the downward pressing process, the first cutter cuts the film on the upper surface of the cup-coupled connection. Simultaneously, the second cutter, due to its protruding support surface, directly abuts the lower surface of the cup-coupled connection. As the first cutter moves, it removes material from the lower surface or creates a clear indentation on the lower surface. This effectively prevents deformation of the sheet material during the punching and shearing process, ensuring accuracy and consistency. The cut or indentation at the cup-coupled connection facilitates subsequent separation of individual cups from the cup-coupled connection. The first pressing surface intersects with the first sliding surface to form a first cutting edge. As the first cutter moves downward, the first cutting edge cuts the upper surface of the cup-coupled connection along a predetermined trajectory. The second pressing surface intersects with the second sliding surface to form a second cutting edge. When the second cutter contacts the lower surface of the cup-coupled connection, the second cutting edge cuts or indents it, resulting in a sharper blade that can more easily penetrate the material. The staggered arrangement prevents interference between the first and second cutting edges. A cutting groove is provided on the support surface, and a third sliding surface is provided within the cutting groove. The third sliding surface extends from the second sliding surface, allowing the first, second, and third sliding surfaces to remain in the same plane during the cutting process, preventing the first cutter from shifting during its descent. When the height of the first cutter's blade is lower than the height of the lower surface of the cup-jointing cut, the first cutter is in a cutting state, at which point the cup-jointing connection is severed. Simultaneously, the first sliding surface of the first cutter extends into the cutting groove along the third sliding surface, providing guidance and support.
[0006] Furthermore, the first sliding surface and the second sliding surface are located in the same vertical plane.
[0007] By adopting the above technical solution, the first sliding surface and the second sliding surface are in the same vertical plane, which can make the cutting between the first cutter and the second cutter smoother and facilitate the processing of the connection between the coupler cups.
[0008] Furthermore, the first cutter has a cutting state and a cutting state for cutting off the connection of the coupling cup. When the first cutter is in the cutting state, the first sliding surface and the third sliding surface are staggered in any horizontal direction and the first sliding surface and the second sliding surface partially overlap in any horizontal direction. When the first cutter is in the cutting state, the first sliding surface and the second sliding surface completely overlap in any horizontal direction and the first sliding surface and the third sliding surface partially overlap in any horizontal direction. The first cutter extends into the cutting groove.
[0009] By adopting the above-mentioned technical solution, it can be seen that the first cutting tool has two usage states. When in the cutting state, the first sliding surface and the third sliding surface are staggered in any horizontal direction and the first sliding surface and the second sliding surface partially overlap in any horizontal direction. When in the cutting state, the first sliding surface and the second sliding surface completely overlap in any horizontal direction and the first sliding surface and the third sliding surface partially overlap in any horizontal direction. The first cutter extends into the cutting groove. According to the different positions of the coupling cup connection, the usage state of the first cutter can be adjusted, and the function is richer.
[0010] Furthermore, an avoidance groove is provided on one side of the cutting groove close to the third sliding surface. When the first cutter is in a cutting state, a gap is provided between the first blade and the bottom surface of the avoidance groove.
[0011] By adopting the above-mentioned technical solution, it can be seen that an avoidance groove is added on the side of the cutting groove close to the third sliding surface, so that when the first cutter is in the cutting state and fully extends into the cutting groove, the first blade is avoided, thereby preventing the first cutter from being subjected to impact force during the descent process. When the first cutter cuts the cup connection, if there is no avoidance groove, the first blade may directly hit the bottom or side wall of the cutting groove, thereby generating a large impact force. This impact force will not only increase the wear of the blade, but may also cause the risk of chipping. Therefore, by providing an avoidance groove, it helps to extend the service life of the tool. At the same time, a gap is provided between the avoidance groove and the first blade. This gap can not only further reduce the impact on the blade, but also increase the space required for the cup connection during shearing, so that the first blade can better act on the cup connection, and can also collect debris dropped from the cup connection during shearing.
[0012] Furthermore, a first corresponding surface parallel to the first extrusion surface and an avoidance surface arranged to intersect with the first corresponding surface are provided in the cutting groove. The avoidance surface intersects with the third sliding surface shown to form an angle a, and the first extrusion surface intersects with the first sliding surface to form an angle b, so that a>b. When the first cutter is in the cutting state, the gap between the first extrusion surface and the avoidance surface is greater than the gap between the first extrusion surface and the first corresponding surface.
[0013] By adopting the above-mentioned technical solution, it can be seen that a first corresponding surface parallel to the first extrusion surface is provided in the cutting groove, which is used to abut against the first extrusion surface during the descending process to ensure the stability of the punching and shearing. A first avoidance surface is also provided, and the avoidance surface intersects with the third sliding surface to form an angle a, and the first extrusion surface intersects with the first sliding surface to form an angle b, a>b, so that when the first cutter is in the cutting state, the gap between the first extrusion surface and the avoidance surface is greater than the gap between the first extrusion surface and the first corresponding surface. There is sufficient gap below the first cutter and the avoidance surface, which can further reduce the impact on the blade.
[0014] Furthermore, the first extrusion surface includes an extrusion bevel and a knife-yielding bevel that are continuously arranged and have different inclination angles. A second corresponding surface parallel to the extrusion bevel is provided in the cutting groove. The knife-yielding bevel intersects with the first sliding surface to form an angle c, and the second corresponding surface forms an angle d with the third sliding surface, so that c>d. When the first cutter is in the cutting state, the gap between the knife-yielding bevel and the second corresponding surface is larger than the gap between the extrusion bevel and the second corresponding surface.
[0015] Using the aforementioned technical solution, it can be seen that by providing an extrusion bevel and a cutter bevel on the first extrusion surface, the cutter bevel intersects with the first sliding surface to form an angle c, and the second corresponding surface forms an angle d with the third sliding surface, with c>d. This ensures that the gap between the cutter bevel and the second corresponding surface is larger than the gap between the extrusion bevel and the second corresponding surface. Providing sufficient clearance below the cutter bevel and the first sliding surface not only further reduces impact on the blade but also serves to collect cup-jointed debris. During the punching and shearing process, some debris is generated after the cup-jointed is cut. Without proper collection measures, the debris will scatter in the work area, affecting production efficiency.
[0016] Furthermore, the first cutter is provided with a limiting surface parallel to the supporting surface, and the limiting surface intersects with the first extrusion surface. When the cup-coupled punching and shearing device performs indentation, the cup-coupled connection is pressed against the supporting surface by the limiting surface, and the sum of the depth L1 of the first cutter cutting into the cup-coupled connection and the depth L2 of the second cutter cutting into the cup-coupled connection is less than the thickness L3 of the cup-coupled connection.
[0017] By adopting the above-mentioned technical solution, it can be seen that the first cutter is provided with a limiting surface parallel to the supporting surface for abutting against the coupling cup connection. By setting the limiting surface to limit the maximum depth L1 of the first cutter during the punching and shearing process, the cutting depth of the first blade can be limited. When the first cutter and the second cutter act together on the coupling cup connection, the sum of their cutting depths is less than the thickness L3 of the coupling cup connection to ensure that the coupling cup connection is not completely cut off. The limiting surface can also squeeze the coupling cup downward to make the coupling cup connection smoother, thereby avoiding deformation due to excessive softness of the material.
[0018] Furthermore, the female mold includes a mold body and an inlay, the inlay is detachably connected to the mold body, and the supporting surface and the cutting groove are provided on the inlay.
[0019] By adopting the above-mentioned technical solution, it can be seen that the die is divided into two parts: the mold body and the insert. The support surface, cutting groove and second cutting knife are all set on the insert. When cutting grooves or blades of different shapes and sizes are required according to different usage requirements, it is only necessary to replace the insert without changing the entire mold body. It is convenient, fast and cost-saving.
[0020] Furthermore, the die is provided with a plurality of cavities arranged at intervals, and the support surface is provided between two adjacent cavities.
[0021] Using the aforementioned technical solution, the spacing of the cavities allows for the simultaneous placement of multiple cups in the die, improving production efficiency by allowing multiple cups to be processed in a single stamping or shearing operation. The position and shape of the cavities ensure the stability of the cups during processing. The support surfaces create indentations at the cup connections. During the stamping or shearing process, the support surfaces contact specific areas of the cups, applying sufficient pressure to create the desired indentation or shearing. This ensures accurate indentation or shearing, and the presence of the support surfaces reduces deformation or damage to the cups during processing.
[0022] Furthermore, a plurality of first cutters are fixed on the die-cutting assembly. The plurality of first cutters are divided into a cutting cutter and a creasing cutter. The blade height of the cutting cutter is lower than the blade height of the creasing cutter.
[0023] Using the aforementioned technical solution, it can be seen that the first cutter includes a cutting cutter and a creasing cutter. The cutting cutter is used to cut the connection between the cups, while the creasing cutter is used to indent the connection between the cups. Different processing effects can be achieved by adjusting the height of the blade. When the die-cutting assembly is pressed down, the cutting cutter's blade, which is lowered to a lower position, will first contact the cups and perform the severing operation. The creasing cutter, with its blade at a higher position, will contact the cups after or simultaneously with the severing operation, leaving the desired indentation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0032] Example 1:
[0033] like Figure 1 and Figure 2 As shown, a cup-coupled punching and shearing device includes a die-cutting assembly 1 and a die 2. The die-cutting assembly 1 opens and closes relative to the die 2. The die 2 is provided with a support surface 21 that abuts and supports the connection points 4 of two adjacent cup-coupled cups. The die-cutting assembly 1 is provided with a first cutter 11 for pressing and cutting the connection points 4 of the cup-coupled cups. The first cutter 11 is provided with a first sliding surface 13 and a first extrusion surface 12. The first extrusion surface 12 intersects with the first sliding surface 13 to form a first blade 14. The first sliding surface 13 is parallel to the opening and closing direction of the die-cutting assembly 1. The support surface 21 is provided with a cutting groove 22 and a second cutter 24 protruding toward one side of the die-cutting component 1. The second cutter 24 is provided with a second sliding surface 28 and a second extrusion surface 25. The second extrusion surface 25 intersects with the second sliding surface 28 to form a second blade 29. The first sliding surface 13 and the second sliding surface 28 form a shear fit. The first extrusion surface 12 and the second extrusion surface 25 are staggered. The cutting groove 22 is provided with a third sliding surface 23. The second sliding surface 28 and the third sliding surface 23 are located in the same plane.
[0034] It can be understood that the die-cutting component 1 performs an opening and closing movement relative to the die 2, so that it has two states in the working state. State 1: The relative position of the die-cutting component 1 and the die 2 is adjusted to the preset starting point. The cup-jointing connection 4 is placed in the area between the first cutter 11 and the second cutter 24. At this time, the first cutter 11 is in a high position, ensuring a safe distance from the cup-jointing connection 4 to avoid contact, thereby ensuring the stability of the cup-jointing connection during the positioning process; State 2: As the die-cutting component 1 moves further, the first cutter 11 descends and approaches the second cutter 24. During the dynamic process, the first cutter 11 docks with the cup-jointing connection 4 to perform a punching and shearing action. Depending on the specific use requirements, the first cutter 11 can punch out an indentation or completely cut off the cup-jointing connection 4.
[0035] Specifically, the die-cutting assembly 1 opens and closes relative to the die 2. During the punching and shearing operation, the first cutter 11 located in the die-cutting assembly 1 approaches the die 2. The die 2 is provided with a support surface 21, which stably supports the lower surface of the cup-coupling joint 4 during the punching and shearing process. The first sliding surface 13 is parallel to the opening and closing direction of the die-cutting assembly 1, ensuring that when the die-cutting assembly 1 presses downward, the first cutter 11 descends smoothly along a predetermined trajectory without deviation. The second sliding surface 28 shears against the first sliding surface 13, allowing the first cutter 11 and the second cutter 24 to act parallel to the upper and lower surfaces of the cup-coupling joint 4 during the punching and shearing process. During the downward pressing process, the first cutter 11 will cut the film on the upper surface of the cup-coupled connection 4. At the same time, the second cutter 24 can directly abut the lower surface of the cup-coupled connection 4 due to the protruding support surface 21. As the first cutter 11 moves, the material on the lower surface is removed, or a clear indentation is formed on the lower surface. This effectively avoids deformation of the sheet material during the punching and shearing process, ensuring the accuracy and consistency of the punching and shearing. The cup-coupled connection 4 is cut or indented, which facilitates the subsequent separation of individual cups from the cup-coupled connection. The first extrusion surface 12 intersects with the first sliding surface 13 to form a first blade 14. As the first cutter 11 moves downward, the first blade 14 cuts the upper surface of the coupling joint 4 along a predetermined trajectory. The second extrusion surface 25 intersects with the second sliding surface 28 to form a second blade 29. When the second cutter 24 contacts the lower surface of the coupling joint 4, the second blade 29 cuts or indents it, making the blade sharper and easier to penetrate. The staggered arrangement prevents interference between the first and second blades 14, 29. The support surface 21 is provided with a cutting groove 22, which is provided with a third sliding surface 23. The third sliding surface 23 extends from the second sliding surface 28, ensuring that the first, second, and third sliding surfaces 13, 28, and 23 remain in the same plane during the cutting process, preventing the first cutter 11 from shifting during its descent. When the height of the first cutter 11's blade is lower than the height of the lower surface of the coupling joint, the first cutter 11 is in a cutting state, and the coupling joint 4 is severed. At the same time, the first sliding surface 13 of the first cutter 11 extends into the cutting groove 22 along the third sliding surface 23, playing a guiding and supporting role.
[0036] Example 2:
[0037] Based on the above embodiment, the first sliding surface 13 and the second sliding surface 28 are located in the same vertical plane.
[0038] It can be understood that the first sliding surface 13 and the second sliding surface 28 are in the same vertical plane, which can make the cutting between the first cutter 11 and the second cutter 24 smoother and facilitate the processing of the coupling cup connection 4.
[0039] Preferably, the first cutter 11 can have a cutting state and a cutting state of cutting off the cup connection 4. When the first cutter 11 is in the cutting state, the first sliding surface 13 and the third sliding surface 23 are staggered in any horizontal direction and the first sliding surface 13 and the second sliding surface 28 partially overlap in any horizontal direction. When the first cutter 11 is in the cutting state, the first sliding surface 13 and the second sliding surface 28 completely overlap in any horizontal direction and the first sliding surface 13 and the third sliding surface 23 partially overlap in any horizontal direction. The first cutter 11 extends into the cutting groove 22.
[0040] It can be understood that when in the cutting state, the first sliding surface 13 and the third sliding surface 23 are staggered in any horizontal direction and the first sliding surface 13 and the second sliding surface 28 partially overlap in any horizontal direction. When in the cutting state, the first sliding surface 13 and the second sliding surface 28 completely overlap in any horizontal direction and the first sliding surface 13 and the third sliding surface 23 partially overlap in any horizontal direction. The first cutter 11 extends into the cutting groove 22. According to the different positions of the cup connection 4, the use state of the first cutter 11 can be adjusted, and the function is richer.
[0041] In one embodiment, Figure 3 As shown, an avoidance groove 221 is provided on one side of the cutting groove 22 close to the third sliding surface 23 . When the first cutter 11 is in the cutting state, a gap is provided between the first blade 14 and the bottom surface of the avoidance groove 221 .
[0042] It is understood that a relief groove 221 is provided on the side of the cutting groove 22 near the third sliding surface 23 to provide relief for the first blade 14 when the first cutter 11 is in the cutting state and fully inserted into the cutting groove 22, thereby protecting the first cutter 11 from impact during its descent. Without the relief groove 221, when the first cutter 11 cuts the cup-joint 4, the first blade 14 may directly impact the bottom or sidewall of the cutting groove 22, generating a significant impact force. This impact force not only increases blade wear but also risks chipping. Therefore, the provision of the relief groove 221 helps extend the tool's service life. Furthermore, a gap is provided between the relief groove 221 and the first blade 14. This gap not only further reduces impact on the blade but also increases the space required for shearing the cup-joint 4, allowing the first blade 14 to better engage the cup-joint 4.
[0043] Specifically, a first corresponding surface 15 parallel to the first extrusion surface 12 and an avoidance surface 16 intersecting the first corresponding surface 15 are provided in the cutting groove 22. The avoidance surface 16 is provided on the side close to the third sliding surface 23. The avoidance surface 16 intersects with the third sliding surface 23 shown to form an angle b. The first extrusion surface 12 intersects with the first sliding surface 13 to form an angle a, so that b>a. When the first cutter 11 is in the cutting state, the gap between the first extrusion surface 12 and the avoidance surface 16 is greater than the gap between the first extrusion surface 12 and the first corresponding surface 15.
[0044] It can be understood that a first corresponding surface 15 parallel to the first extrusion surface 12 is provided in the cutting groove 22, which is used to abut against the first extrusion surface 12 during the descending process to ensure the stability of the punching and shearing. A avoidance surface 16 is also provided, and the avoidance surface 16 intersects with the third sliding surface 23 to form an angle b, and the first extrusion surface 12 intersects with the first sliding surface 13 to form an angle a, a>b, so that when the first cutter 11 is in the cutting state, the gap between the first extrusion surface 12 and the avoidance surface 16 is greater than the gap between the first extrusion surface 12 and the first corresponding surface 15, and there is sufficient gap below the first cutter 11 and the avoidance surface 16, which can further reduce the impact on the blade.
[0045] In another embodiment, Figure 4 As shown, the first extrusion surface 12 includes an extrusion bevel 121 and a knife-leaving bevel 122 that are continuously arranged and have different inclination angles. The knife-leaving bevel 122 is arranged on the side close to the first sliding surface 13. A second corresponding surface parallel to the extrusion bevel 121 is provided in the cutting groove 22. The knife-leaving bevel 122 intersects with the first sliding surface 13 to form an angle c, and the second corresponding surface forms an angle d with the third sliding surface 23, so that c>d. When the first cutter 11 is in the cutting state, the gap between the knife-leaving bevel 122 and the second corresponding surface is larger than the gap between the extrusion bevel 121 and the second corresponding surface.
[0046] It can be understood that by providing the extrusion bevel 121 and the knife-yielding bevel 122 on the first extrusion surface 12, the knife-yielding bevel 122 intersects with the first sliding surface 13 to form an angle c, and the second corresponding surface and the third sliding surface form an angle d, c>d, so that the gap between the knife-yielding bevel 122 and the second corresponding surface is larger than the gap between the extrusion bevel 121 and the second corresponding surface, and sufficient gap is provided below the knife-yielding bevel 122 and the first sliding surface 13, which can not only further reduce the impact on the blade.
[0047] As a preferred Figure 5As shown, the first cutter 11 is provided with a limiting surface 123 parallel to the supporting surface 21, and the limiting surface 123 intersects with the first extrusion surface 12. When the cup-coupled punching and shearing device performs indentation, the cup-coupled connection 4 is pressed against the supporting surface 21 by the limiting surface 123, and the sum of the depth L1 of the first cutter 11 cutting into the cup-coupled connection 4 and the depth L2 of the second cutter cutting into the cup-coupled connection 4 is less than the thickness L3 of the cup-coupled connection 4.
[0048] It can be understood that a limiting surface 123 parallel to the supporting surface 21 is provided on the first cutter 11 for contacting the coupling cup connection 4. By setting the limiting surface 123 to limit the maximum depth L1 of the first cutter 11 during the punching and shearing process, the cutting depth of the first blade 14 can be limited. When the first cutter 11 and the second cutter 24 act together on the coupling cup connection 4, the sum of their cutting depths is less than the thickness L3 of the coupling cup connection 4 to ensure that the coupling cup connection 4 is not completely cut off. The limiting surface 123 can also squeeze the coupling cup downward to make the coupling cup connection 4 smoother, thereby avoiding deformation due to excessive softness of the material.
[0049] Example 3:
[0050] Based on the above embodiments, Figure 6 and Figure 7 As shown, the die 2 includes a die body 26 and an insert 27 . The insert 27 is detachably connected to the die body 26 , and the support surface 21 and the cutting groove 22 are provided on the insert 27 .
[0051] It can be understood that the die 2 is divided into two parts: a die body 26 and an insert 27. The support surface 21, the cutting groove 22 and the second cutter 24 are all arranged on the insert 27. When cutting grooves 22 or blades of different shapes and sizes are required according to different usage requirements, it is only necessary to replace the insert 27 without changing the entire die body 26. It is convenient, fast and cost-effective.
[0052] like Figure 7 As shown, the die 2 is provided with a plurality of cavities 3 arranged at intervals, and the support surface 21 is provided between two adjacent cavities 3 .
[0053] As will be appreciated, the spacing of the cavities 3 allows for the simultaneous placement of multiple cup couplings on the die 2, improving production efficiency by allowing multiple cup couplings to be processed in a single stamping or shearing operation. The position and shape of the cavities 3 ensure the stability of the cup coupling during processing. The support surfaces 21 provide shearing indentations at the cup coupling joints 4. During the stamping or shearing process, the support surfaces 21 contact specific areas of the cup coupling and apply sufficient pressure to form the desired indentation or shearing operation. This ensures accurate indentation or shearing, and the presence of the support surfaces 21 reduces deformation or damage to the cup coupling during processing.
[0054] Further, such as Figure 3 As shown, a plurality of first cutters 11 are fixed on the die-cutting assembly 1. The plurality of first cutters 11 are divided into cutting cutters and creasing cutters. The blade height of the cutting cutter is lower than the blade height of the creasing cutter.
[0055] It will be appreciated that the first cutter 11 comprises a cutting cutter and a creasing cutter. The cutting cutter is used to cut the cup coupling joint 4, while the creasing cutter is used to indent the cup coupling joint 4. Different processing effects can be achieved by adjusting the height of the blade. When the die-cutting assembly 1 is pressed downward, the cutting cutter's blade, which is lowered to a lower position, will first contact the cup coupling and perform the severing operation. The creasing cutter, with its blade at a higher position, will contact the cup coupling after or simultaneously with the severing operation, leaving the desired indentation.
