Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping, in particular to a waste box tray capable of detecting the capacity status of waste materials. Background Art

[0002] Hot stamping technology: Hot stamping is referred to as hot forming. The steel plate for hot forming (tensile strength of about 550MPa) is heated to above 900℃ in a heating furnace. The metallographic structure of the steel plate is transformed into austenite under high temperature conditions. After the steel plate is heated and taken out of the furnace, it is transported to a hot forming mold with a water cooling system by an automated clamp. It is stamped and formed at high temperature. After forming, the mold is quickly cooled to below 100℃. The high-temperature austenite structure is transformed into martensite, which increases the tensile strength of the part to more than 1300MPa. This process is a hot forming process. In the hot forming process, according to needs, punching is sometimes performed on the part while the mold is being formed. The required holes are punched out on the high-temperature steel plate by the punch on the mold.

[0003] The punched waste falls into the waste collection box inside the mold. Since the hot forming punching is carried out on the steel plate at a temperature of about 700℃, the punched waste has a very high temperature. Since the steel plate has an aluminum silicon coating, this coating is soft at high temperature, so the waste has a certain viscosity, which is easy to accumulate and difficult to disperse. When the waste accumulates to a certain height, the machine must be stopped to deal with the waste, otherwise it is easy to block the mold discharge hole, causing mold damage and abnormal shutdown.

[0004] After searching, it is found that the existing hot forming molds and hot punching waste discharge are in a high-temperature state. Due to the high temperature and the aluminum-silicon coating, the surface lubricity is poor, and the waste cannot be discharged by cold punching waste slides. The waste can only be collected by using the waste box in the mold. Moreover, since the waste has a certain viscosity and is easy to accumulate, it is necessary to frequently stop the machine to clean the waste. Each batch (calculated as 10 hours) needs to be stopped for cleaning 4 times. Even so, there is a certain risk of waste accumulation causing blockage in punching discharge. Utility Model Content

[0005] In view of the existing patents, in order to solve the technical problems of frequent shutdowns and blockage of mold discharge holes caused by the accumulation of hot punching waste in the production process of hot formed parts, the utility model provides a waste box tray that can detect the waste capacity status.

[0006] The technical solution adopted by the utility model is: a waste box tray capable of detecting the waste capacity status, comprising:

[0007] A hot stamping structure, comprising a lower die base and an upper die base mounted on top of the lower die base, wherein the upper die base is provided with an upper mold cavity, and the lower die base is provided with a lower mold cavity;

[0008] A waste box body, the waste box body being mounted on the top of the lower die base;

[0009] A tray assembly is mounted on the top of the lower die base and is used to place a waste box and vibrate it;

[0010] The tray assembly includes a tray body axially connected to the lower mold base, a connecting structure installed on one side of the tray body, a stopper installed at the bottom of the lower mold cavity, and an induction structure installed on one side of the stopper.

[0011] Furthermore, the connecting structure includes an extension plate fixedly welded to one side of the pallet body, a first connecting rod installed on the top of the extension plate, a first strong magnetic magnet installed at the end of the first connecting rod, a second connecting rod installed at the bottom of the upper mold base and a second strong magnetic magnet installed at the end of the second connecting rod.

[0012] Furthermore, the sensing structure includes a protective shell fixedly mounted on one side of the block, a first sensing plate fixedly mounted on the inner wall of the protective shell, a second sensing plate welded to the bottom of the inner top wall of the protective shell through a return spring, and a sensing rod fixedly mounted on the second sensing plate, and the sensing contacts on the first sensing plate cooperate with the connecting contacts on the second sensing plate.

[0013] Furthermore, a through hole is provided on the second sensing plate, the second sensing plate is fixedly sleeved on the outside of the sensing rod, a guide hole is provided on the top of the protective shell, and the sensing rod is installed inside the guide hole.

[0014] Furthermore, the first strong magnetic magnet cooperates with the second strong magnetic magnet.

[0015] Furthermore, an upper die punch is installed on the upper mold cavity, a lower die discharge hole is opened in the lower mold cavity, the upper die punch cooperates with the lower die discharge hole, and the waste box body is installed at the bottom of the lower die discharge hole.

[0016] The beneficial effects of the utility model are:

[0017] 1. The second connecting rod is driven by the upper die base, so that the first strong magnetic magnet and the second strong magnetic magnet are close to and adsorbed. When the upper die base is lifted, the upper die base drives the first connecting rod to move upward through the second connecting rod, the second strong magnetic magnet and the first strong magnetic magnet. The first connecting rod drives one end of the tray body to move upward through the extension plate, and the tray body drives the waste box body to tilt until the block blocks the extension plate from continuing to move upward. At this time, the first strong magnetic magnet is separated from the second strong magnetic magnet, and the waste box body vibrates. The waste in the waste box body is affected by gravity and vibration, and the waste moves to the rear end of the waste box body to avoid waste accumulation and clogging of the lower die discharge hole, thereby avoiding waste damage caused by clogging of the discharge hole and waste of maintenance costs.

[0018] 2. When the waste box body is about to be filled with waste, the weight of the waste box body and the tray body increases to a certain extent. The magnetic force between the first strong magnetic magnet and the second strong magnetic magnet is not enough to lift the extension plate. At this time, the first induction plate and the second induction plate will not be displaced as the upper die base and the lower die base are separated. The device no longer receives the induction signal. At this time, the device stops production and prompts the staff to clean the waste box body, reducing the number of shutdowns and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-4 The utility model is further described.

[0032] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a waste box tray capable of detecting the waste capacity status, comprising: a hot stamping structure 1, a waste box body 4 and a tray assembly 5;

[0033] The hot stamping structure 1 includes a lower die base 101 and an upper die base 102 mounted on the top of the lower die base 101. The upper die base 102 defines an upper mold cavity 2, and the lower die base 101 defines a lower mold cavity 3.

[0034] The waste box body 4 is mounted on the top of the lower die base 101;

[0035] An upper die punch 6 is mounted on the upper mold cavity 2 , and a lower die discharge hole 7 is opened in the lower mold cavity 3 . The upper die punch 6 cooperates with the lower die discharge hole 7 , and the waste box body 4 is mounted at the bottom of the lower die discharge hole 7 .

[0036] like Figure 1-4 As shown, the tray assembly 5 is installed on the top of the lower mold base 101, and the tray assembly 5 is used to place the waste box and vibrate it.

[0037] The tray assembly 5 includes a tray body 501 axially connected to the lower mold base 101, a connecting structure 502 installed on one side of the tray body 501, a stopper 503 installed at the bottom of the lower mold cavity 3, and an induction structure 504 installed on one side of the stopper 503. The connecting structure 502 includes an extension plate 5021 fixedly welded to one side of the tray body 501, a first connecting rod 5022 installed on the top of the extension plate 5021, a first strong magnetic magnet 5023 installed at the end of the first connecting rod 5022, a second connecting rod 5024 installed at the bottom of the upper mold base 102, and a second strong magnetic magnet 5025 installed at the end of the second connecting rod 5024. The first strong magnetic magnet 5023 cooperates with the second strong magnetic magnet 5025.

[0038] Furthermore, the sensing structure 504 includes a protective shell 5041 fixedly mounted on one side of the block 503, a first sensing plate 5042 fixedly mounted on the inner wall of the protective shell 5041, a second sensing plate 5044 welded to the bottom of the inner top wall of the protective shell 5041 through a reset spring 5043, and a sensing rod 5045 fixedly mounted on the second sensing plate 5044. The sensing contacts on the first sensing plate 5042 cooperate with the connecting contacts on the second sensing plate 5044.

[0039] Furthermore, a through hole is opened on the second sensing plate 5044, and the second sensing plate 5044 is fixedly sleeved on the outside of the sensing rod 5045. A guide hole is opened on the top of the protective shell 5041, and the sensing rod 5045 is installed inside the guide hole.

[0040] Working principle: When in use, through the cooperation of the upper die base 102 and the lower die base 101, the upper die base 102 and the lower die base 101 are pressed together, and the stamping work is completed by the upper die punch 6. The waste falls into the interior of the waste box body 4 through the lower die discharge hole 7. The upper die base 102 drives the second connecting rod 5024, so that the first strong magnetic magnet 5023 and the second strong magnetic magnet 5025 are close to and adsorbed. When the upper die base 102 is lifted, the upper die base 102 is connected to the second connecting rod 5024, the second strong magnetic magnet 5025 and the first strong magnetic magnet. 5023 drives the first connecting rod 5022 to move upward, and the first connecting rod 5022 drives one end of the support plate body to move upward through the extension plate 5021, and the tray body 501 drives the waste box body 4 to tilt. When the tray body 501 rises to a certain height, the extension plate 5021 contacts the sensing rod 5045, and the sensing rod 5045 drives the second sensing plate 5044 to press the reset spring 5043 upward, and the second sensing plate 5044 contacts the first sensing plate 5042, completing one rising work until the stop block 503 blocks the extension plate 5021. 021 continues to move upward, at this time the first strong magnetic magnet 5023 and the second strong magnetic magnet 5025 are separated, the waste box body 4 vibrates, and the waste in the waste box body 4 is affected by gravity and vibration, and the waste moves to the rear end of the waste box body 4 to prevent the waste from accumulating and blocking the lower die discharge hole 7. When the waste box body 4 is about to be filled with waste, the weight of the waste box body 4 and the tray body 501 increases to a certain extent, and the magnetic force between the first strong magnetic magnet 5023 and the second strong magnetic magnet 5025 is not enough to lift the extension plate 5021. The first sensing plate 5042 and the second sensing plate 5044 will not be displaced as the upper die base 102 and the lower die base 101 are separated. The device no longer receives the sensing signal. At this time, the device stops production and prompts the staff to clean the waste box body 4, reducing the number of shutdowns. The machine is shut down for cleaning once per shift, and each shutdown for cleaning takes 10 minutes. The shutdown for cleaning is reduced by 3 times, saving 30 minutes. The effective production time of each batch is increased by 30 minutes, which improves work efficiency and avoids the waste of maintenance costs caused by damage to the punch due to blockage of the discharge hole.
