Description

A waste cutting device Technical Field

[0001] This application relates to the field of waste cutting technology, and more specifically, to a waste cutting device. Background Technology

[0002] In the hardware industry's production process, stamping is an important processing method widely used in the forming and manufacturing of various metal parts. Among these processes, stamping long strips of thin metal sheets is a common production step. However, the stamping process inevitably generates a large amount of waste after the parts are processed. Currently, this stamping waste is generally collected manually. After collection, in order to achieve efficient recycling or facilitate subsequent processing, operators must hold the waste material, place it on the cutting equipment, manually adjust the cutting dimensions, and perform the cutting operation.

[0003] However, the manual collection and cutting of waste materials is extremely inefficient, greatly prolonging the production cycle and making it difficult to meet the pace of modern large-scale production. In addition, the sharp edges of the waste materials can easily cut operators during manual collection, posing a serious safety hazard. Furthermore, manual operation is labor-intensive and has high labor costs, increasing the operational burden on enterprises. Summary of the Invention

[0004] The purpose of this application is to provide a waste cutting device that can solve the technical problems raised in the background art.

[0005] This application provides a waste material cutting device, including a base, a punching die frame fixed on the base, an inlet for waste sheet to pass through, a cutting component for punching and cutting the waste sheet passing through the inlet, and a waste chute for guiding the cut waste sheet falling off the punching die frame on one side.

[0006] Furthermore, the cutting assembly includes a lower die cutter, a cutting blade, a cutting blade backrest, a connecting member, a pressure-bearing member, and an elastic reset member. The punching die frame is provided with a limiting groove communicating with the feed port. The lower die cutter is fixedly disposed in the limiting groove, and the top of the lower die cutter is flush with the bottom of the feed port. The cutting blade is movably disposed in the limiting groove and located above the lower die cutter. The cutting blade is connected to the pressure-bearing member through the connecting member. The pressure-bearing member is connected to the punching die frame through the elastic reset member. The cutting blade backrest is disposed on the opening side of the limiting groove, and the cutting blade backrest is slidably connected to the cutting blade.

[0007] Furthermore, the back of the cutter is detachably connected to the punching die frame, the cutting blade is fixed on the connector, the top of the connector is provided with a connecting clip, and the bottom of the pressure-bearing member is provided with a connecting slot that matches the connecting clip. The connector engages with the pressure-bearing member through the cooperation of the connecting clip and the connecting slot.

[0008] Furthermore, the elastic reset member is a spring, which is located between the punching die frame and the pressure-bearing member. The cross-section of the pressure-bearing member is an inverted L-shape. One end of the elastic reset member is fixedly connected to the top of the punching die frame, and the other end of the elastic reset member is fixedly connected to the bottom of the protruding end of the pressure-bearing member.

[0009] Furthermore, it also includes a support base, on which a pair of limiting locking grooves are symmetrically provided, and a locking component for locking the base to the support base is provided in the limiting locking groove.

[0010] Furthermore, the locking assembly includes a movable connecting block, a locking bolt, a clamping block, and a movable support block. The movable connecting block is adapted to the limiting locking groove and is slidably disposed within the limiting locking groove. The movable connecting block has a threaded hole adapted to the locking bolt, and the clamping block has a through hole adapted to the locking bolt. The movable support block is located between the clamping block and the support base. When the lower end of the locking bolt passes through the clamping block and is screwed into the threaded hole, the base can be locked onto the support base by the clamping block.

[0011] Furthermore, the discharge end of the waste chute extends beyond the support base.

[0012] The beneficial effects of this utility model are:

[0013] In use, this utility model involves securely mounting the waste cutting device on a stamping table and placing a waste collection frame at the discharge end of the waste chute. When the metal sheet is conveyed to the stamping table, the upper stamping die descends to complete the stamping of the metal parts. The sheet then continues to be conveyed forward to the inlet of this device. When the upper stamping die performs the next stamping operation, its downward pressing action drives the cutting component to operate synchronously. The cutting component cuts the remaining waste material after the metal sheet has been processed. The separated waste sheet automatically slides into the collection frame, guided by the waste chute, achieving centralized recycling and subsequent processing of the waste. Compared with existing technologies, this device, through the linkage design of stamping and cutting, completely eliminates the cumbersome process of manually collecting and cutting waste, significantly improving production efficiency, avoiding the risk of workers being scratched by sharp waste, greatly enhancing operational safety, reducing manpower input, lowering labor intensity, effectively controlling labor costs, and alleviating the operational burden on enterprises.

[0026] Specific implementation examples:

[0027] As shown in Figures 1-3, this application provides a scrap cutting device, including a base 1, a punching die frame 2 fixedly mounted on the base 1, an inlet 21 for scrap sheet metal to pass through, a cutting component 3 for punching and cutting the scrap sheet metal passing through the inlet 21, and a scrap chute 4 for guiding the scrap sheet metal falling after cutting on one side of the punching die frame 2. In use, the scrap cutting device is securely installed on a stamping table, and a scrap collection frame is placed corresponding to the discharge end of the scrap chute 4. When the metal sheet metal is conveyed to the stamping table, the upper stamping die descends to complete the stamping of the metal parts. The sheet metal then continues to be conveyed forward to the inlet 21 of this device, awaiting the upper stamping die... During the next round of stamping, the downward pressing action of the upper stamping die drives the cutting component 3 to operate synchronously. The cutting component 3 cuts the remaining scrap material after the metal sheet has been processed into parts. The cut and separated scrap sheet automatically slides into the scrap collection box by the guidance of the scrap chute 4, realizing the centralized recycling and subsequent processing of scrap. Compared with the existing technology, this device completely eliminates the cumbersome process of manually collecting and cutting scrap through the linkage design of stamping and cutting, significantly improves production efficiency, avoids the risk of workers being scratched by contact with sharp scrap, greatly enhances work safety, reduces manpower input, reduces labor intensity, effectively controls labor costs, and reduces the burden of enterprise operation.

[0028] As shown in Figures 1-3, the cutting assembly 3 includes a lower die 31, a cutting blade 32, a cutting blade backing 33, a connecting member 34, a pressure-bearing member 35, and an elastic reset member 36. The punching die frame 2 is provided with a limiting groove 22 communicating with the feed inlet 21. The lower die 31 is fixedly installed in the limiting groove 22, with its top flush with the bottom of the feed inlet 21. The cutting blade 32 is movably installed in the limiting groove 22 and positioned above the lower die 31. The cutting blade 32 is connected to the pressure-bearing member 35 via the connecting member 34, and the pressure-bearing member 35 is connected to the elastic reset member 36. Connected to the punching die set 2, the cutter backrest 33 is located on the opening side of the limiting groove 22, and the cutter backrest 33 is slidably connected to the cutting blade 32; in the initial state, the pressure-bearing part 35 is connected to the punching die set 2 through the elastic reset part 36. When no external force is applied, the elastic reset part 36 is in a natural state, and the elastic reset part 36 pushes the pressure-bearing part 35 upward, so that the cutting blade 32 is separated from the lower die blade 31 and remains in a standby state. At this time, the scrap sheet can pass smoothly through the limiting groove 22 from the feed port 21; during the cutting process, when the upper punching die presses down on the pressure-bearing part 35, the cutting blade 32 is connected to the lower die blade 31 and remains in a standby state. When the pressing part 35 is pressed, the pressed part 35 overcomes the elastic force of the elastic reset part 36 under pressure, driving the connecting part 34 to move downward, thereby causing the cutting blade 32 to move downward along the limiting groove 22. Since the cutting blade backrest 33 is located on the opening side of the limiting groove 22 and is slidably connected to the cutting blade 32, it provides lateral support and guidance for the cutting blade 32, ensuring that the cutting blade 32 moves vertically downward accurately. Finally, the cutting blade 32 cooperates with the lower die 31 to punch and cut the scrap sheet that passes through the feed port 21 and is located between the two. During the reset process, the punching... After the upper die completes the stamping and cutting action and rises, the pressure-bearing component 35, which has lost the external force, is reset upward under the elastic force of the elastic reset component 36. It drives the cutting blade 32 to rise synchronously through the connecting component 34 and return to the initial standby position, waiting for the next cutting. The cutting component 3 is driven to work by the downward pressing action of the upper die. There is no need to set up an additional independent power source, realizing the linkage between stamping and cutting, reducing the complexity of the equipment structure, reducing costs, and improving the degree of production automation. Scrap cutting can be completed without manual operation, thus improving production efficiency.

[0029] As shown in Figures 1-3, the cutter backrest 33 is detachably connected to the punching die frame 2. The cutting blade 32 is fixed on the connector 34. The top of the connector 34 is provided with a connecting clip 341, and the bottom of the pressure-bearing member 35 is provided with a connecting slot 351 that matches the connecting clip 341. The connector 34 is engaged with the pressure-bearing member 35 through the cooperation of the connecting clip 341 and the connecting slot 351. Specifically, the cutter backrest 33 is provided with a mounting hole, and the punching die frame 2 is provided with a threaded hole. The cutter backrest 33 is detachably installed on the punching die frame 2 through the cooperation of bolts with the mounting hole and the threaded hole. When the cutting blade 32 is worn or damaged and needs to be replaced, the cutter backrest 33 is removed from the punching die frame 2. Due to the engaging design of the connector 34 and the pressure-bearing member 35, the connector 34 and the pressure-bearing member 35 can be separated to replace the cutting blade 32 on the connector 34. The replacement is simple and convenient.

[0030] As shown in Figure 3, the elastic reset element 36 is a spring. The elastic reset element 36 is located between the punching die frame 2 and the pressure member 35. The cross-section of the pressure member is an inverted L shape. One end of the elastic reset element 36 is fixedly connected to the top of the punching die frame 2, and the other end of the elastic reset element 36 is fixedly connected to the bottom of the protruding end of the pressure member 35. Specifically, there are two elastic reset elements 36, which are symmetrically arranged. Common springs are used as the reset element. The structure is simple, easy to manufacture and install. The elastic characteristics of the spring are stable, which can ensure that the pressure member 35 and the cutting blade 32 can reliably reset after each cut, ensuring the continuity and consistency of the cutting action and reducing equipment failures caused by abnormal reset.

[0031] As shown in Figures 1-3, the waste cutting device of this application also includes a support base 5. A pair of limiting locking grooves 51 are symmetrically provided on the support base 5. The limiting locking grooves 51 are provided with locking components 6 for locking the base 1 to the support base 5. The cooperation between the symmetrical limiting locking grooves 51 and the locking components 6 simplifies the installation process of the base 1. The device can be quickly installed, disassembled or adjusted in position according to actual needs, improving the flexibility of equipment layout and adapting to changes in different production scenarios.

[0032] As shown in Figures 1 and 2, the locking assembly 6 includes a movable connecting block 61, a locking bolt 62, a clamping block 63, and a movable support block 64. The movable connecting block 61 is adapted to the limiting locking groove 51 and is slidably disposed within the limiting locking groove 51. The movable connecting block 61 has a threaded hole adapted to the locking bolt 62. The clamping block 63 has a through hole adapted to the locking bolt 62. The movable support block 64 is located between the clamping block 63 and the support base 5. When the lower end of the locking bolt 62 is passed through the clamping block 63 and screwed into the threaded hole, the base 1 can be locked onto the support base 5 through the clamping block 63. When installing the base 1 of the waste cutting device, first slide the movable connecting block 61 adapted to the limiting locking groove 51 into the limiting locking groove 51 to ensure that the movable connecting block 61 is within the limiting locking groove 51. Next, place the base 1 on the corresponding position on the support 5, so that the base 1 is in contact with the movable support block 64 and the clamping block 63. Pass the locking bolt 62 through the through hole of the clamping block 63 and align it with the threaded hole on the movable connecting block 61. Screw the locking bolt 62 into the threaded hole. As the locking bolt 62 is continuously screwed into the threaded hole, the downward pull of the locking bolt 62 causes the clamping block 63 to gradually press down. The clamping block 63 presses the base 1 tightly onto the support 5. At the same time, the movable support block 64 provides a reverse support force. The three work together to achieve a firm lock between the base 1 and the support 5. When disassembling, turn the locking bolt 62 and pull it out of the threaded hole of the movable connecting block 61 to release the pull on the clamping block 63. The clamping block 63 no longer presses the base 1, and the base 1 can be easily removed from the support 5.

[0033] As shown in Figures 1-3, the discharge end of the waste chute 4 extends beyond the support base 5, allowing waste to fall directly into the pre-placed waste collection box. This avoids waste accumulating below the device or around the support base 5, simplifies the waste collection process, improves waste collection efficiency, and keeps the work area clean.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
