Description

Technical Field

[0001] This application relates to the field of waste material handling, and in particular to a waste material cutting device. Background Technology

[0002] In the field of stamping, sheet materials, after being stamped using progressive or compound dies, typically generate regularly structured scrap. This scrap is usually in the form of a rectangular frame with regular edges and holes or internal structures formed during stamping. In traditional processes, the separation and handling of scrap mainly rely on the tail cutting device built into the die. This device generally consists of upper and lower cutting die supports, which use the shearing force generated during die closing to cut the connecting parts between adjacent scrap frames, thus dispersing the scrap. The cut scrap then falls naturally under gravity onto the conveyor belt below, where it is transported out by the conveyor system for centralized recycling or further processing.

[0003] However, existing technologies have significant limitations: because waste materials are typically complete rectangular frames with considerable structural integrity and rigidity, they are highly susceptible to interference with the conveyor belt surface during unloading and transport. Mechanical friction or instability can even cause the waste material to entangle and accumulate on the conveyor belt rollers or surface. This problem not only hinders the normal operation of the conveyor belt and reduces conveying efficiency, but also requires frequent shutdowns for cleaning, severely impacting the continuity and automation level of stamping production, while simultaneously increasing equipment maintenance costs and operational safety risks. Utility Model Content

[0004] To improve conveying efficiency, this application provides a tail material cutting device.

[0005] The tail material cutting device provided in this application adopts the following technical solution: A tail material cutting device includes an upper punch, a lower die, and a first cutter. The upper punch and the lower die are disposed at the discharge end of a stamping die. The upper punch and the lower die are respectively fixedly connected to the upper die and the lower die of the stamping die. The first cutter is fixedly connected to the end of the upper punch facing the lower die. The end of the lower die facing the upper punch is provided with a first cutting groove. The first cutter is slidably connected to the groove wall of the first cutting groove.

[0006] By adopting the above technical solution, during the die closing process of the stamping die, the upper punch and lower die shear the waste frame, cutting the individual waste frame from the middle to form two smaller half-frame structures, reducing the overall size and rigidity of the waste, significantly reducing the possibility of it getting tangled when it comes into contact with the conveyor belt, thereby improving the stability and efficiency of waste conveying.

[0007] Preferably, the upper punch includes a first mounting block and a second mounting block. The first mounting block is detachably connected to the upper die of the stamping die, and the second mounting block is fixedly connected to the first mounting block. The length direction of the second mounting block is perpendicular to the length direction of the first mounting block, and the distances from the second mounting block to both ends of the first mounting block are equal. The lower die includes a first placement block and a second placement block. The first placement block is detachably connected to the lower die of the stamping die, and the second placement block is fixedly connected to the first placement block. The length direction of the second placement block is perpendicular to the length direction of the first placement block, and the second placement block and the second mounting block are directly opposite each other. The first cutter is detachably connected to the second mounting block, and the first cutting groove is provided on the second placement block.

[0008] By adopting the above technical solution, stable and precise centering and shearing of the waste frame is achieved, ensuring that it is reliably divided into two uniformly sized half-frame structures. This effectively reduces the overall size and rigidity of the waste, significantly reducing the risk of it entanglement on the conveyor belt. The detachable connection design greatly facilitates the replacement, maintenance, and adjustment of key components such as the cutter, improving the applicability and service life of the equipment. As a result, the overall stability and production efficiency of waste conveying are significantly improved, and equipment maintenance costs are reduced.

[0009] Preferably, the second mounting block is provided with a fixing port that extends vertically through the second mounting block, and the upper end of the first cutter is provided with a connecting groove. After the bolt passes through the fixing port, it is threaded to the groove wall of the connecting groove.

[0010] By adopting the above technical solution, the bolts pass through the fixing port of the second mounting block and are directly fastened to the connecting groove at the upper end of the first cutter, thus achieving a firm and precise positioning connection between the first cutter and the upper punch. This improves the installation rigidity and stability of the cutter when subjected to impact loads during high-speed shearing, and effectively prevents loosening or displacement.

[0011] Preferably, the first placement block has a hanging groove at one end away from the second placement block, the hanging groove extends away from the upper punch to penetrate the first placement block, and the downward-facing groove wall of the hanging groove is used to abut against the lower die of the stamping die.

[0012] By adopting the above technical solution, the first placement block can be directly hung from top to bottom and abut against the corresponding edge or boss of the lower die of the stamping die, realizing the rapid and accurate positioning and installation of the lower die, and effectively preventing displacement caused by horizontal force or vibration during stamping operations.

[0013] Preferably, it further includes a second cutter, which is fixedly connected to one end of the first mounting block facing the first placement block. There are two second cutters, which are respectively located on both sides of the second mounting block, and the distances from the two second cutters to the second mounting block are equal. The end of the first placement block facing the first mounting block is provided with a second cutting groove, which is provided with two cutting grooves, and the second cutting grooves are arranged opposite to the second cutters one by one.

[0014] By adopting the above technical solution, the second cutter cuts the waste material into a square frame structure, and the first cutter cuts the square frame into a half-frame structure. All cutters are connected to the upper punch for easy replacement.

[0015] Preferably, the two ends of the second groove are continuous along the length of the second placement block, and the height of the bottom of the second groove decreases as it moves away from the stamping die.

[0016] By adopting the above technical solution, the waste material generated during the shearing process can automatically slide out along the inclined surface of the groove from high to low, away from the stamping die, by its own gravity and the thrust of the stamping action. This achieves smooth, efficient, and automatic discharge of waste material. It effectively avoids the accumulation and blockage of waste material in the cutting groove, reduces the frequency of manual cleaning, ensures continuous and stable operation of the equipment, and further improves the overall production efficiency.

[0017] Preferably, along the length of the first placement block, one end of the second placement block is provided with a clearance opening, the clearance opening is connected to the first cutting groove, and the groove wall of the first cutting groove facing the clearance opening is provided as a shearing surface, the shearing surface is used to slide with the first cutter.

[0018] By adopting the above technical solution, the clearance reduces the deformation of waste material, facilitates shearing, reduces the probability of waste material deformation entering the first cutting groove, facilitates waste material movement, and improves conveying efficiency.

[0019] Preferably, the upper punch has an upper weight-reducing opening, and the lower die has a lower weight-reducing opening.

[0020] By adopting the above technical solutions, while ensuring the overall structural strength and rigidity, the mass of moving parts is effectively reduced, the inertial impact and energy consumption during equipment operation are reduced, the response speed and accuracy of stamping actions are improved, the heat dissipation performance of the mold is improved, and material costs are saved, thus achieving the dual goals of equipment lightweighting and performance optimization.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. During the die closing process of the stamping die, the upper punch and lower die shear the scrap frame, cutting the individual scrap frame from the middle to form two smaller half-frame structures. This reduces the overall size and rigidity of the scrap, significantly reducing the possibility of it getting tangled when it comes into contact with the conveyor belt, thereby improving the stability and efficiency of scrap conveying. 2. It achieves stable and precise centering and shearing of the waste frame, ensuring that it is reliably divided into two uniformly sized half-frame structures, effectively reducing the overall size and rigidity of the waste, significantly reducing the risk of it getting tangled on the conveyor belt. The detachable connection design greatly facilitates the replacement, maintenance and adjustment of key components such as the cutter, improving the applicability and service life of the equipment, thereby significantly improving the stability and production efficiency of waste conveying and reducing equipment maintenance costs. 3. The clearance reduces the deformation of waste material, making it easier to complete the shearing process, reducing the probability of waste material deforming and entering the first cutting groove, facilitating waste material movement, and improving conveying efficiency.
