[0014] The accompanying drawings described herein are for illustrative purposes only and are not intended to limit the scope of this disclosure in any way. Detailed Implementation

[0015] The following description is merely exemplary in nature and is not intended to limit this disclosure, its application, or its uses. It should be understood that throughout the drawings, corresponding reference numerals indicate the same or corresponding parts and features.

[0016] refer to Figures 1 to 4 The diagram illustrates a cutting and waste discharge system or upper die 10. System 10 can cut or trim the panel or body 12 into a desired shape. System 10 can also discharge waste or trimmed portions of the panel 12 from system 10 and guide them to desired support holes or chutes (not shown) for disposal. In this way, system 10 can quickly and repeatedly trim the panel 12 and discharge waste to improve the productivity of the stamping operation.

[0017] System 10 includes a lower post 16, a main pad 18, a plunger or rod 20, and a cutting assembly 22. The lower post 16 is positioned below the main pad 18 and partially supports the panel 12. In other words, the panel 12 can be positioned or placed on the lower post 16 such that a portion of the panel 12 to be trimmed extends beyond the perimeter of the lower post 16.

[0018] Main pad 18 can be in the first position ( Figure 1 ) and second position ( Figures 2 to 4 The main pad 18 moves between the lower post 16 and the panel 12 disposed on the lower post 16 in the first position, and in the second position, the main pad 18 engages with the lower post 16 to clamp the panel 12. When the main pad 18 is in the first position, a gap is formed between the main pad 18 and the lower post 16, allowing the panel 12 to be placed on the lower post 16. When the main pad 18 is in the second position, the lower surface of the main pad 18 may contact or engage a portion of the upper surface of the panel 12, while the upper surface of the lower post 16 engages a portion of the lower surface of the panel 12 to clamp the panel 12. In one embodiment, the main pad 18 can be moved by one or more motors 17 ( Figure 6 (For example, a hydraulic motor, an electric motor, etc.) can move between a first position and a second position. In other forms, the main pad 18 can be moved between the first position and the second position by another device (such as a nitrogen cylinder that applies force or pressure to the main pad 18 using nitrogen).

[0019] The main pad 18 includes a main body portion 18a and an extension portion 18b. The extension portion 18b extends outward beyond the periphery of the main body portion 18a (and the periphery of the lower post 16) and defines an opening 26 configured to receive a plunger 20, as will be described in more detail below. The extension portion 18b is located between the parts of the cutting assembly 22, and the opening 26 extends vertically through the extension portion 18b. In other words, the opening 26 opens through the upper side of the extension portion 18b and opens through the lower side of the extension portion 18b. In the example shown, the opening 26 is a stepped opening, wherein the diameter of the first portion of the opening 26 is larger than the diameter of the second portion of the opening 26.

[0020] Continue to refer to Figures 1 to 4 And refer to other sources Figure 5 The plunger 20 is configured to discharge and guide the trimmed or scrap portion of the panel 12 from the system 10 after the panel 12 has been cut. That is, after the panel 12 has been trimmed, the scrap portion of the panel 12 must be discharged from the system 10 and guided into a chute (not shown). The plunger 20 is configured to discharge and guide the trimmed portion of the panel 12 into the chute, allowing another panel 12 to be loaded onto the system 12 and trimmed. The plunger 20 is in a first position ( Figure 1 and Figure 2 ) and the second position ( Figure 3 and Figure 4 The plunger 20 is movably coupled to the main pad 18. In a first position, the plunger 20 is spaced apart from the panel 12. In a second position, the plunger 20 contacts a portion of the panel 12 to discharge from the system 10 and guide said portion of the panel 12. The plunger 20 is made of a hardened or rigid material and extends through the extension 18b and the cutting member 22a of the cutting assembly 22. In other words, the plunger 20 extends through the opening 26 of the extension 18b and the opening 28 of the cutting member 22a. A biasing member 30 (e.g., a spring) is disposed within a first portion of the opening 26 and biases the plunger 20 toward the first position. In other words, the biasing member 30 surrounds a portion of the plunger 20 within the first portion of the opening 26 and contacts the plunger 20 to bias the plunger 20 toward the first position.

[0021] like Figure 5 As shown, the plunger 20 includes a first threaded portion 32a and a second threaded portion 32b spaced apart from the first threaded portion 32a. That is, the first threaded portion 32a is located above the extension 18b of the main pad 18, and the second threaded portion 32b is located below the extension 18b of the main pad 18 (i.e., the extension 18b is disposed between the first threaded portion 32a and the second threaded portion 32b). One or more nuts 34 are threadedly engaged with the first threaded portion 32a, and one or more nuts 36 are threadedly engaged with the second threaded portion 32b. In this way, by rotating the plunger 20 relative to the nuts 34, 36, the plunger 20 can be vertically adjusted relative to the main pad 18 (or the panel 12).

[0022] An upper washer 38 is located between the nut 34 and the biasing member 30 and engages both the nut 34 and the biasing member 30. In this way, the biasing member 30 biases the plunger 20 toward a first position. A lower washer 40 is located between the nut 36 and an extension 18b of the main washer 18 and can selectively engage the extension 18b. That is, when the biasing member 30 biases the plunger 20 toward the first position, the lower washer 40 engages the extension 18b. When the plunger 20 moves toward a second position, the lower washer 40 is spaced apart from the extension 18b. The plunger 20 also has a proximal end 20a and a distal end 20b. The proximal end 20a is configured to engage a cutting assembly 22 such that the cutting assembly 22 moves the plunger 20 from the first position toward the second position, as will be described in more detail below. In the example shown, the proximal end 20a has a flat surface. In some forms, the proximal end 20a may have a curved surface. The distal end 20b is configured to contact a portion of the panel 12 to discharge said portion of the panel 12 from the system 10 and into a chute (not shown). In the example shown, the distal end 20b has a rounded or arcuate tip. In some forms, the distal end 20b may have a flat surface or another externally shaped surface to facilitate the discharge of said portion of the panel 12 from the system 10 and into the chute.

[0023] The cutting assembly 22 is configured to cut or trim the panel 12 and includes a cutting member 22a and an upper hoof 22b. The cutting member 22a can be positioned in a non-cutting position ( Figure 1 and Figure 2 ) and cutting position ( Figure 3 and Figure 4 The cutting member 22a moves between the main pad 18 and the lower post 16. In the non-cutting position, the cutting member 22a is spaced apart from the panel 12. In the cutting position, the cutting member 22a trims the panel 12. The cutting member 22a can move to the cutting position in response to the main pad 18 and the lower post 16 clamping the panel 12. That is, once the main pad 18 moves to the second position such that the main pad 18 and the lower post 16 engage to clamp the panel 12, the cutting member 22a can move to the cutting position where the cutting edge 44 of the cutting member 22a trims the panel 12. In the example shown, the periphery 46 of the main body portion 18a of the main pad 18 is flush with the periphery 48 of the lower post 16. In some forms, when the cutting member 22a moves between the cutting position and the non-cutting position, the cutting edge 44 can be along the periphery of the main body portion 18 and the lower post 16, respectively. 46、48 Proceeding. Before the cutting member 22a moves to the cutting position, the plunger 20 is prevented from contacting the panel 12. In this way, the plunger 20 does not apply force to the panel 12 until the cutting member 22a begins to trim the panel 12 (or for a period of time thereafter), which reduces deformation of the panel 12.

[0024] The cutting member 22a defines an opening 28 that opens through the upper side and the lower side of the cutting member 22a. A bushing 52 is disposed within the opening 28 of the cutting member 22a and receives a portion of the plunger 20. In other words, the plunger 20 can extend through the bushing 52, wherein the plunger is supported by the bushing 52 and is movable relative to the bushing 52. In this way, the bushing 52 can prevent the plunger 20 from bending or deflecting as the plunger 20 discharges the trimmed portion from the system 10 and into the chute. In the example shown, the upper axial end of the bushing 52 is flush with the upper surface of the cutting member 22a, and the lower axial end of the bushing 52 is flush with the lower surface of the cutting member 22a. In some forms, the upper axial end of the bushing 52 is recessed from the upper surface of the cutting member 22a (i.e., within the opening 28), and the lower axial end of the bushing 52 is recessed from the lower surface of the cutting member 22a (i.e., within the opening 28).

[0025] Continue to refer to Figures 1 to 4 The upper hoof 22b is connected to the cutting member 22a and moves as the cutting member 22a moves. That is, when the cutting member 22a is in the non-cutting position, the upper hoof 22b is in the first state ( Figure 1 and Figure 2 ), and when the cutting member 22a is in the cutting position, the upper hoof 22b is in the second state ( Figure 3 and Figure 4 The upper hoof 22b includes a striking plate 54 configured to engage the proximal end 20a of the plunger 20 to overcome the biasing force of the biasing member 30, thereby moving the plunger 20 from a first position toward a second position. That is, when the upper hoof 22b is in the first state, the striking plate 54 is spaced apart from the proximal end 20a of the plunger 20, and when the upper hoof 22b is in the second state, the striking plate engages the proximal end 20a of the plunger 20. In one embodiment, the upper hoof 22b and the cutting member 22a can be connected via a device 56 ( Figure 6 For example, a nitrogen cylinder can be used to apply force or pressure to one or both of the upper hoof 22b and the cutting member 22a to move them. In another form, the upper hoof 22b and the cutting member 22a can be moved by one or more motors (e.g., hydraulic motors, electric motors, etc.).

[0026] refer to Figure 6 The controller 60 communicates with the device 56 of the cutting assembly 22 and the motor 17 of the main pad 18, and can monitor and control the operation of the device 60 and the motor 17 based on the received data. In one example, the controller 60 communicates with the device 60 and the motor 17 using wireless communication protocols (e.g., Bluetooth®, cellular, Wi-Fi, Near Field Communication (NFC), Ultra Wideband (UWB), etc.).

[0027] refer to Figures 1 to 4 and Figure 7 An exemplary control algorithm 200 for cutting and discharging trimmed portions of panel 12 is shown. Processing can begin once the main pad 18 is moved to a first position spaced apart from the lower post 16. At 204, panel 12 is placed on the lower post 16, between the main pad 18 and the lower post 16. Figure 1 At position 208, the control algorithm uses controller 60 to move the main pad 18 from the first position to the second position, so that the main pad 18 and the lower post 16 cooperate to clamp the panel 12. Figure 2 At 212, the control algorithm uses controller 60 to move the cutting component from the non-cutting position to the cutting position to cut panel 12. Figure 3 It should be understood that the cutting member 22a moves from the non-cutting position to the cutting position in response to the main pad 18 and the lower post 16 clamping the panel 12.

[0028] At position 216, plunger 20 moves from a first position to a second position, in which plunger 20 contacts trimming portion 59 of panel 12 to remove trimming portion 59 from system 10. Figure 4 The material is discharged and enters the chute. As described above, the plunger 20 moves from the first position to the second position via the cutting assembly 22 (i.e., the upper hoof 22b of the cutting assembly 22). It should be understood that the plunger 20 is prevented from contacting the portion 59 of the panel 12 before the cutting member 22a moves to the cutting position. In this way, the plunger 20 does not apply force to the panel 12 before being cut by the cutting member 22a, thereby suppressing deformation of the panel 12. At 220, the trimmed panel 12 is removed from the system 10, and the system 10 is reloaded (i.e., another panel 12 is placed on the lower post 16 for trimming).

[0029] The system disclosed herein provides the benefit of allowing the plunger 20 to contact the panel 12 at a desired position during or after the panel 12 has been sheared by the cutting member 22a. In this way, deformation of the panel 12 prior to cutting is suppressed, and the trimmed portion 59 of the panel 12 is properly discharged from the system 10 and enters the chute. In other words, it may be desirable to cut the angled portion of the panel 12 using the cutting member 22a; however, applying force to the panel 12 via the plunger 20 before the panel 12 is cut could cause deformation of the panel 12 and also cause malfunction of the system 10. Therefore, by allowing the plunger 20 to contact the panel 12 at a desired position during or after the panel 12 has been sheared by the cutting member 22a, deformation of the panel 12 can be suppressed and proper discharge of the trimmed portion 59 can be achieved.

[0030] Unless otherwise expressly indicated herein, all numerical values ​​indicating mechanical / thermal properties, percentage of composition, dimensions and / or tolerances or other characteristics should be understood as being modified by the words “about” or “approximately” when describing the scope of this disclosure. Such modification is desired for various reasons, including: industrial practice; material, manufacturing and assembly tolerances; and testing capabilities.

[0031] As used herein, the phrases A, B, and C at least one should be interpreted as representing logic (A or B or C) using the non-exclusive logic "or", and should not be interpreted as representing "at least one of A, at least one of B, and at least one of C".

[0032] In this application, the terms “controller” and / or “module” may refer to, be part of, or include the following: application-specific integrated circuit (ASIC); digital, analog, or mixed analog / digital discrete circuit; digital, analog, or mixed analog / digital integrated circuit; composable logic circuit; field-programmable gate array (FPGA); processor circuitry (shared, dedicated, or grouped) that executes code; memory circuitry (shared, dedicated, or grouped) that stores code executed by the processor circuitry; other suitable hardware components that provide the described functionality; or combinations of some or all of the foregoing, such as in a system-on-a-chip.

[0033] The term memory is a subset of the term computer-readable medium. As used herein, the term computer-readable medium does not cover transient electrical or electromagnetic signals propagated through a medium (such as on a carrier wave); therefore, the term computer-readable medium can be considered tangible and non-transient.
