[0002] Hardware parts refer to metal product components processed by stamping machines. These components are usually made of various metal materials, such as steel, copper, and aluminum. During the stamping process, a waste removal mechanism is needed to discharge the waste generated during stamping to ensure the smooth progress of the stamping work and the processing quality of the hardware parts.

[0003] Existing waste removal solutions for metal stamping machines have the following shortcomings: the waste removal mechanism and the stamping machine are mostly rigidly integrated, making maintenance and upgrades difficult and resulting in poor cross-model compatibility; the material discharge port lacks a guiding structure, making it easy for waste to get stuck; the receiving plate is mostly a fixed single plate, limiting the amount of waste removed at one time, and the waste is prone to slipping during reciprocating motion; the single guide rail or simple slide design makes the receiving plate prone to tilting and jamming during reciprocating motion, affecting production continuity; the receiving plate and drive components are mostly non-removable structures, making cleaning and replacement time-consuming and labor-intensive.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1 to 5 As shown, this is an embodiment of the present invention, relating to a waste removal mechanism for a metal stamping machine, including a mechanism body 10. The mechanism body 10 is used to receive metal waste generated during processing by the stamping machine 20. The mechanism body 10 includes a reciprocating collection device 30. The reciprocating collection device 30 is detachably installed on one side of the processing table 40 of the stamping machine 20. The reciprocating collection device 30 includes a support base 31, a guide rail assembly 50, an adjusting connection assembly 60, a waste receiving tray 70, and a reciprocating drive module 80. The support base 31 is connected to the machine via a detachable structure. The guide rail assembly 50 is mounted on one side of the processing table 40; the guide rail assembly 50 is mounted above the support base 31; the adjusting connection assembly 60 is slidably connected to the guide rail assembly 50; multiple waste receiving trays 70 are provided, and the multiple waste receiving trays 70 are connected to the adjusting connection assembly 60; the reciprocating drive module 80 is connected to the adjusting connection assembly 60 for transmission, and the reciprocating drive module 80 is used to drive the adjusting connection assembly 60 to reciprocate linearly along the guide rail assembly 50, so as to discharge the waste received by the waste receiving trays 70 from the working area of ​​the stamping machine 20.

[0029] Specifically, the waste discharge function is integrated into an independent reciprocating collection device 30, which is detachably connected to the processing table 40 of the stamping machine 20, facilitating equipment upgrades, maintenance, and cross-model adaptation; multiple waste receiving trays 70 receive waste in parallel, increasing the amount of waste discharged at one time and adapting to high-frequency stamping scenarios; the drive module drives the receiving trays to reciprocate, actively discharging waste, avoiding the safety hazards of manual cleaning, and effectively improving cleaning efficiency; in some embodiments, the detachable structure is a bolt or snap-fit ​​structure, realizing detachable connection.

[0030] like Figure 2 As shown, the processing table 40 includes a stamping station 41 and a waste removal station 42. The stamping station 41 is used to install the stamping machine 20, and the height of the stamping station 41 is greater than the height of the waste removal station 42. The waste removal station 42 is located on one side of the stamping station 41 and is used to install the reciprocating collection device 30. Specifically, by utilizing the height difference between the stamping station 41 and the waste removal station 42, the waste material naturally slides down to the receiving tray, reducing the residue of waste material in the material drop path. The stamping and waste removal functions are separated to avoid equipment interference and improve the overall layout rationality.

[0031] like Figure 2 As shown, the waste discharge station 42 is provided with a positioning groove 43 arranged opposite to it, and the bottom of the support base 31 is connected to the positioning groove 43 by fastening screws. Specifically, the positioning groove 43 provides an installation reference for the support base 31, shortens the assembly time, and reduces manual installation errors; the fastening screws, in conjunction with the positioning groove 43, counteract the inertial force of reciprocating motion, prevent the support base 31 from loosening, and improve the stability of equipment operation.

[0032] like Figure 5 As shown, the number of guide rail assemblies 50 is set to two, and the two guide rail assemblies 50 are arranged in parallel. Specifically, the dual guide rail assemblies 50 symmetrically support the adjusting connecting assembly 60, distribute the load, and avoid the risk of tipping over from a single guide rail; the parallel-arranged guide rail assemblies 50 constrain the motion trajectory, improve the linear accuracy of reciprocating motion, and prevent the connecting plate from jamming.

[0033] like Figure 5 As shown, the guide rail assembly 50 is a linear sliding guide rail, which includes a guide rail base 51 and a slider body 52. ​​The guide rail base 51 is connected to the support base 31. The upper part of the slider body 52 is fixedly connected to the adjustment connection assembly 60 and slides with the guide rail base 51. Specifically, the sliding engagement between the slider body 52 and the guide rail base 51 significantly reduces reciprocating motion resistance, reduces energy consumption and component wear; the standardized structure of the linear sliding guide rail ensures the motion accuracy of the adjustment connection assembly 60 and improves the consistency of waste discharge position.

[0034] like Figure 4 and Figure 5As shown, the adjusting connection assembly 60 includes a mounting plate 61, a baffle 62, a circular guide rod 63, and several mounting blocks 64. The mounting plate 61 is fixedly connected to the top of the slider body 52. ​​There are two baffles 62, which are respectively connected to both sides of the mounting plate 61 via a detachable structure. The circular guide rod 63 is located between the two baffles 62. The mounting blocks 64 are movably engaged with the circular guide rod 63. Specifically, the mounting blocks 64 move along the circular guide rod 63, which can flexibly adjust the spacing or arrangement of the scrap receiving trays 70 to accommodate stamping scrap of different sizes. The baffles 62 and the mounting plate 61 are detachable, which facilitates the later addition or replacement of the scrap receiving trays 70, improving the flexibility of processing.

[0035] like Figure 4 As shown, the two side edges of the waste receiving tray 70 are folded upward to form retaining sides 71, which are used to limit the slippage of the received waste. Specifically, during reciprocating motion, the retaining sides 71 prevent the waste from falling to the side, ensuring that the waste is effectively carried out of the working area.

[0036] like Figure 4 As shown, the waste receiving tray 70 has several mounting through holes 72 on its upper surface, which are used for detachable connection with the mounting block 64. Specifically, through the mounting through holes 72, the waste receiving tray 70 can be quickly disassembled for cleaning or replacement, solving the maintenance problem of material accumulation and wear on the tray after long-term use; it can also be replaced with waste receiving trays 70 of different materials or structures such as wear-resistant and corrosion-resistant materials to adapt to special stamping scenarios.

[0037] like Figure 5 As shown, the reciprocating drive module 80 includes a reciprocating cylinder 81, a reciprocating connecting plate 82, and a transmission plate 83. The reciprocating cylinder 81 is mounted on the bottom of the support base 31 and connected to the reciprocating connecting plate 82. The reciprocating connecting plate 82 is vertically connected to the transmission plate 83. The end of the transmission plate 83 facing away from the reciprocating connecting plate 82 is connected to the mounting plate 61. Specifically, the reciprocating cylinder 81 has a fast drive response and simple control, which is suitable for the intermittent working rhythm of the press 20. The transmission structure composed of the reciprocating connecting plate 82 and the transmission plate 83 evenly transmits the cylinder thrust to the adjusting connection assembly 60, avoiding local stress concentration.

[0038] like Figure 3 As shown, the lower die base 21 of the stamping machine 20 is provided with a through-hole sump 22. The inner wall of the sump 22 is integrally formed with a sloping surface 23. The sloping surface 23 extends obliquely along the direction of waste falling from the sump 22. The sloping surface 23 is used to guide the waste to slide into the waste receiving tray 70. Specifically, the sloping surface 23 changes the trajectory of the waste falling, preventing the waste from getting stuck in the sump 22 due to its irregular shape; the guiding effect of the sloping surface 23 accelerates the falling of the waste, reduces the falling time, and is suitable for high-speed stamping scenarios.

[0039] The working principle of this utility model is as follows:

[0040] When the stamping machine 20 finishes processing the hardware parts, the scrap material leaves the mold and falls from the through-hole 22 of the lower mold base 21. The scrap discharge slope 23, which is integrally formed on the inner wall of the scrap discharge port 22, extends at an angle along the natural falling direction of the scrap material, forcibly changing the falling trajectory of the scrap material, avoiding the scrap material from getting stuck at the edge of the scrap discharge port 22 due to its irregular shape, and ensuring that the scrap material falls smoothly into the scrap receiving tray 70 below.

[0041] When the waste falls into the waste receiving tray 70, the upward-folding retaining sides 71 on both sides of the tray form a U-shaped receiving space, which restrains the waste from the side; even if the tray accelerates or decelerates during reciprocating motion, the retaining sides can prevent the waste from sliding down, ensuring that the waste is stably retained in the receiving tray.

[0042] When the reciprocating drive module 80 is started, the cylinder piston rod extends and retracts, pushing the reciprocating connecting plate 82 to move linearly. The vertically connected transmission plate 83 moves synchronously, driving the adjusting connecting component 60 to reciprocate linearly along two parallel linear guide rails. When the scrap receiving tray 70 moves with the adjusting connecting component 60 to below the stamping station 41, it receives the scrap falling from the discharge port 22. Then it moves to the outside of the scrap discharge station 42, carrying the scrap out of the working area of ​​the stamping machine 20, completing one scrap discharge cycle.

[0043] The scrap receiving tray 70 is detachably connected to the mounting block 64 of the adjusting connection assembly 60 through the mounting through hole 72. It can also slide along the round guide rod 63 of the adjusting connection assembly 60 to adjust the spacing, adapting to stamping scrap of different sizes. If the tray is worn or accumulates material, it can be quickly disassembled for cleaning and replacement.

[0044] The baffle 62 and mounting plate 61 of the adjusting connection component 60 are detachable, and the number of connectors can be increased or replaced with special function connectors in the future; the detachable connection between the support base 31 and the processing table 40 also supports cross-model adaptation or equipment upgrade.

[0045] This utility model features a reciprocating collection device 30 with a modular design that allows for independent disassembly, supports quick assembly and disassembly, cross-model adaptation, and functional expansion, effectively reducing maintenance costs. Dual parallel guide rails ensure stable movement, while the inclined feeding surface 23 guides waste material precisely into the receiving tray. The retaining side 71 prevents slippage, resulting in high waste removal efficiency. The spacing and quantity of the waste receiving trays 70 are adjustable to accommodate waste materials of different sizes. The high and low station design of the processing table 40 is compatible with various types of stamping machines 20. The waste receiving trays 70 and the support base 31 have detachable structures, reducing the cost of replacing vulnerable parts. Multiple waste receiving trays 70 receive waste material in parallel, and with the accelerated guidance of the inclined feeding surface 23, waste removal time is shortened, adapting to the continuous operation requirements of automated production lines.

[0046] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
