Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and more specifically, to a stamping device for a dishwasher housing. Background Technology

[0002] During the stamping process of dishwasher shells, especially during blanking and punching, a large amount of peripheral waste is generated. This waste is usually ring-shaped or sheet-shaped and relatively large. If it is not handled in a timely and effective manner, it will accumulate around the mold or on the equipment platform, which will not only affect production efficiency and occupy working space, but may also damage the mold and equipment, and even cause safety hazards.

[0003] Chinese Patent (Application No.: CN223043401U) discloses an elbow mold for seamless stamping elbow production; it includes a base, a support rod, a top plate, a dual-axis cylinder, a first arc plate, a second arc plate, and a cleaning module. The cleaning module includes a support frame, a drive cylinder, a mounting frame, an arc scraper, an air pump, a transport pipe, and an air nozzle. The support frame is fixedly connected to one side of the second arc plate. The drive cylinder is fixedly connected to the support frame and located on the outer side wall of the support frame. The mounting frame is fixedly connected to the output end of the drive cylinder. An air nozzle is provided at the upper end of the mounting frame, and an arc scraper is provided at the lower end of the mounting frame. The air pump is fixedly connected to the mounting frame and located on the outer side wall of the mounting frame. One end of the transport pipe is connected to the output end of the air pump, and the other end of the transport pipe is connected to the air nozzle.

[0004] The aforementioned existing technologies have addressed the problem of residues (including waste) from the mold production process interfering with subsequent operations and have attempted to solve this issue through cleaning devices. However, such designs primarily focus on cleaning after forming, and still lack effective solutions for the immediate, online processing of large volumes of waste generated during the stamping process, especially how to efficiently and automatically crush and remove it from the work area. Utility Model Content

[0005] Based on this, in order to solve the problem that traditional equipment cannot achieve continuous automated waste processing, this utility model provides a dishwasher shell stamping device, the specific technical solution of which is as follows:

[0006] A dishwasher housing stamping device, comprising

[0007] The upper die structure includes an upper template, a nitrogen spring, and a movable scrap punch. The upper template is driven by a slide block on a punch press. The nitrogen spring is mounted on the upper template. The movable scrap punch is connected to the nitrogen spring, and the nitrogen spring provides a continuous force to the movable scrap punch.

[0008] A crushing device, said crushing device being used to crush waste materials;

[0009] The lower die structure includes a lower waste cutter, a lower pad, and a waste slide plate. The lower die structure is used to cooperate with the movable waste punch and the upper die plate to cut off the outer ring waste. The lower pad is used to accommodate the waste, and the waste slide plate is used to guide the waste onto the crushing device.

[0010] In the aforementioned dishwasher casing stamping equipment, when the press slide descends, it first drives the upper template and the movable waste punch to work together to complete the initial cutting of the outer ring waste. As the press slide continues to descend, the lower waste cutter presses against the movable waste punch and the upper template, cutting the already cut outer ring waste into sliding waste and falling waste. When the press slide returns, the falling waste falls into the lower pad under gravity, while the sliding waste slides out of the mold via the waste slide plate. By setting a unique "moving waste punch-lower waste cutter" shearing structure and combining it with a "waste slide plate-crushing device," a complete waste processing production line is constructed. After being cut, the waste is automatically guided by the waste slide plate to the crushing device for secondary crushing, ultimately becoming smaller particles that are easier to recycle. The entire process requires no manual intervention, achieving online automated processing. By employing a nitrogen spring to drive the moving scrap punch, the nitrogen spring provides a continuous, stable, and buffered force. This ensures that the force applied by the moving scrap punch when it engages with the lower scrap cutter to cut the scrap is gentle and controllable, avoiding the damage such as cracking and wear caused by traditional rigid impacts to the scrap punch and lower scrap cutter edge. The design of the lower pad provides temporary space for the cut scrap and smoothly connects with the scrap slide, ensuring smooth scrap transfer and avoiding the risk of scrap getting stuck in critical parts of the mold. This dishwasher casing stamping equipment solves the problem of continuous automated scrap processing that traditional equipment cannot achieve.

[0011] Furthermore, the movable waste punch can elastically extend and retract relative to the upper template under the action of a nitrogen spring.

[0012] Furthermore, the top of the waste cutting tool is configured as a cutting edge or plane that can abut against the lower end face of the movable waste punch.

[0013] Furthermore, the waste slide plate is configured as an inclined slide, with the high end of the waste slide plate located near the lower waste cutter to receive the falling waste, and the low end of the waste slide plate extending to the crushing device.

[0014] Furthermore, the crushing device includes a storage container, a conveyor line, and a crushing mechanism; the bottom end of the waste slide plate extends to the crushing device; one end of the conveyor line is connected to the crushing mechanism, and the other end of the conveyor line is connected to the storage container.

[0015] Furthermore, the crushing mechanism includes a power unit, a hopper, a frame, and multiple crushing rollers; the frame is located at one end of the conveyor line, the hopper is located on the frame, and the bottom end of the waste material slide plate extends to the hopper.

[0016] Furthermore, the plurality of the crushing rollers are mounted on the frame and rotatably connected to the frame. The output end of the power component is drively connected to the plurality of the crushing rollers. The power component is used to drive the plurality of rollers to rotate. The plurality of crushing rollers cooperate to crush waste materials.

[0017] Furthermore, the power assembly includes a first motor, a gearbox, and a plurality of gears, with one gear corresponding to one of the crushing rollers; the output end of the first motor is connected to the input end of the gearbox, and the output end of the gearbox is connected to one of the gears. The first motor and the gearbox cooperate to drive the plurality of crushing rollers to rotate.

[0018] Furthermore, the conveyor line includes a conveyor belt and a plurality of partition plates, the plurality of partition plates being arranged at intervals and disposed on the conveyor belt. Attached Figure Description

[0029] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0030] like Figure 1-3As shown, a dishwasher shell stamping device according to one embodiment of the present invention includes an upper die structure 1, a crushing device 2, and a lower die structure 3. The upper die structure 1 includes an upper template 11, a nitrogen spring 12, and a movable waste punch 13. The upper template 11 is driven by a slider on a punch press. The nitrogen spring 12 is disposed on the upper template 11. The movable waste punch 13 is connected to the nitrogen spring 12, and the nitrogen spring 12 is used to provide a continuous force to the movable waste punch 13. The crushing device 2 is used to crush waste. The lower die structure 3 includes a lower waste cutter 31, a lower pad 32, and a waste slide plate 33. The lower die structure 3 is used to cooperate with the movable waste punch 13 and the upper template 11 to cut off the outer ring waste. The lower pad 32 is used to accommodate waste, and the waste slide plate 33 is used to guide the waste onto the crushing device 2.

[0031] In the aforementioned dishwasher casing stamping equipment, when the slide block descends on the press, it first drives the upper template 11 and the movable waste punch 13 to work together to complete the initial cutting of the outer ring waste. As the slide block continues to descend, the lower waste cutter 31 presses against the movable waste punch 13 and the upper template 11, cutting the already cut outer ring waste into sliding waste and falling waste. When the slide block returns, the falling waste falls into the lower pad 32 by gravity, while the sliding waste slides out of the mold via the waste slide plate 33. By setting a unique "movable waste punch 13-lower waste cutter 31" shearing structure and combining it with the "waste slide plate 33-crushing device 2", a complete waste processing production line is constructed. After being cut, the waste is automatically guided by the waste slide plate 33 to the crushing device 2 for secondary crushing, ultimately becoming smaller particles that are easier to recycle. The entire process requires no manual intervention, achieving online automated processing. By employing a nitrogen spring 12 to drive the movable waste punch 13, the nitrogen spring 12 provides a continuous, stable, and buffered force. This ensures that when the movable waste punch 13 cooperates with the lower waste cutter 31 to cut the waste, the force is gentle and controllable, avoiding damage such as chipping and wear caused by traditional rigid impacts to the waste punch and the cutting edge of the lower waste cutter 31. The design of the lower pad 32 provides temporary space for the cut waste and smoothly connects with the waste slide plate 33, ensuring smooth waste transfer and avoiding the risk of waste getting stuck in critical parts of the mold. This dishwasher shell stamping equipment solves the problem of continuous automated waste processing that traditional equipment cannot achieve.

[0032] like Figure 1-2As shown, in one embodiment, the movable waste punch 13 is elastically extendable relative to the upper template 11 under the action of the nitrogen spring 12; the top of the lower waste blade 31 is configured as a cutting edge or flat surface that can abut against the lower end face of the movable waste punch 13; the waste slide plate 33 is configured as an inclined slide, with the high end of the waste slide plate 33 located near the lower waste blade 31 to receive the sliding waste, and the low end of the waste slide plate 33 extending to the crushing device 2. Thus, by allowing the movable waste punch 13 to elastically extend and retract under the action of the nitrogen spring 12, it can adaptively maintain optimal contact and pressure when cooperating with the lower waste blade 31, further buffering impact, protecting the cutting edge, and ensuring the stability of the cutting effect; the fact that the top of the lower waste blade 31 can be configured as a cutting edge or a flat surface provides different design options to adapt to different waste characteristics and shearing requirements, increasing the flexibility of mold design.

[0033] like Figure 3-4As shown, in one embodiment, the crushing device 2 includes a storage container 21, a conveyor line 22, and a crushing mechanism 23; the bottom end of the waste material slide plate 33 extends onto the crushing device 2; one end of the conveyor line 22 is connected to the crushing mechanism 23, and the other end of the conveyor line 22 is connected to the storage container 21; the crushing mechanism 23 includes a power component, a hopper 231, a frame 233, and multiple crushing rollers 232; the frame 233 is mounted on one end of the conveyor line 22, the hopper 231 is mounted on the frame 233, and the bottom end of the waste material slide plate 33 extends onto the hopper 231; the multiple crushing rollers 232 are mounted on the frame 233 and rotatably connected to the frame 233, and the output end of the power component is connected to the multiple crushing rollers 232. The multiple crushing rollers 232 are connected by a drive assembly to drive the multiple rollers to rotate. The multiple crushing rollers 232 cooperate to crush waste materials. The drive assembly includes a first motor 234, a gearbox 235, and multiple gears 236. Each gear 236 is connected to one crushing roller 232. The output end of the first motor 234 is connected to the input end of the gearbox 235, and the output end of the gearbox 235 is connected to one of the gears 236. The first motor 234 and the gearbox 235 cooperate to drive the multiple crushing rollers 232 to rotate. The conveyor line 22 includes a conveyor belt 221 and multiple partition plates 222. The multiple partition plates 222 are spaced apart and disposed on the conveyor belt 221. Thus, by setting up a crushing device 2 that includes a crushing mechanism 23, a conveyor line 22, and a storage container 21, the waste generated by the mold is crushed on-site into smaller and more uniform particles, reducing the volume of waste and facilitating subsequent recycling, transportation, and reuse. By adopting a structure in which multiple crushing rollers 232 driven by power components (motor, gearbox 235, gear set 236) cooperate with each other, powerful shearing and extrusion forces can be generated to effectively crush waste of various shapes and hardness.

[0034] Working principle:

[0035] S1: The slide of the punch press moves down, driving the upper template 11 and compressing the nitrogen spring 12, so that the moving scrap punch 13 and the upper template 11 work together to cut off the outer ring scrap of the product;

[0036] S2: The slide block on the punch press continues to descend, and the lower scrap cutter 31 presses against the movable scrap punch 13 and the upper template 11, cutting the outer ring scrap that was cut off in step S1 a second time, separating it into sliding scrap and falling scrap; the secondary cutting action is achieved by the lower scrap cutter 31 resisting the elastic force of the nitrogen spring 12 to block the downward movement of the movable scrap punch 13.

[0037] S3: During the return stroke of the slide block on the punch press, the falling waste material falls directly into the lower pad 32 of the lower die by gravity. At the same time, the falling waste material slides out of the die through the waste material slide plate 33, completing the removal of all waste material.

[0038] S4. Crushing device 2 crushes waste materials.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they 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 these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
