Description

Technical Field

[0001] The utility model relates to the technical field of powder recovery for molding machines, and specifically provides a powder recovery device for molding machines. Background Art

[0002] Hydraulic press molding machines are manufactured based on Pascal's principle and are used to implement processing technologies. They are machines that use liquid as the working medium, utilize the hydrostatic pressure of the liquid, and process products such as metals, rubbers, and powders through pressure changes. Among them, powder hydraulic molding machines are applicable to industries such as powder metallurgy, fine ceramics, magnetic materials, cemented carbides, metal powders, inductive magnetic cores, and related industries that require powder pressing and molding. They are particularly suitable for the pressing and molding of multi-step complex-shaped products. The pressed products are firm and reliable, and the overall structure of the machine is simple, with low failure rates, convenient operation, and easy maintenance.

[0003] Before use, when most hydraulic molding machines are in use, manual cleaning and recovery of excess powder are mostly adopted. Workers use powder recovery machines or simple tools to clean the powder scattered beside the machine molds. Manual cleaning has relatively low efficiency, affects the working efficiency of the machine, consumes labor costs, and also has a certain degree of danger.

[0004] For example, a powder recovery device for a molding machine disclosed in Chinese Patent Publication No. CN220615046U. This recovery device uses a push plate to push the excess powder above into the upper part of the sieve. The motor at the bottom of the sieve drives the eccentric wheel, and the eccentric wheel drives the connecting rod. One end of the connecting rod is hinged to the bottom of the sieve, so that the excess powder pushed by the push plate can fall into the collection box at the bottom of the sieve through the vibration of the sieve. The sieve not only plays a role in filtering larger impurities, but also can break up the agglomerated powder during the pushing process, reducing powder waste and also reducing the labor cost of manual collection.

[0005] First of all, the above-mentioned device uses a push plate to push the powder into the sieve, and while completing powder collection, it also completes powder screening. However, during the powder screening process, due to vibration and the breaking up of agglomerated powder, dust is easily dispersed in the air, thus affecting the lung health of users and the processing environment. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a powder recovery device for a molding machine, which solves the problems raised in the above background art.

[0007] To achieve the above objectives, the present utility model is realized through the following technical solutions: A powder recycling device for a molding machine, comprising a main body of the molding machine. A processing table is arranged directly below the main body of the molding machine. A molding groove for processing is opened in the processing table. A recycling module for recycling and screening is arranged below the molding groove, and closing modules are symmetrically arranged at the left and right ends of the molding groove.

[0008] The closing module includes magnetic suction grooves opened on the side surfaces at both ends of the processing table. A closing plate with an overall concave shape is arranged in the magnetic suction grooves. The closing plate, the processing table, and the molding groove form a closed area. A first recovery pipe with the other end connected to an air extraction pipe is arranged on the closing plate. The other end of the air extraction pipe is connected to an air extraction pump fixedly installed on the side surface of the processing table. The magnetic suction grooves are connected to an external magnetic induction coil assembly, and the material of the closing plate is a permanent magnet. During processing, the magnetic suction state of the magnetic suction grooves is cancelled, and the closing plate can be slid and disassembled to avoid affecting normal molding. After processing, through the magnetic suction fixation between the closing plate and the magnetic suction grooves, the recycling module is closed, avoiding the dust escaping during the recycling process and affecting the health of users and the processing environment. And the dust is enclosed in the processing table and the molding groove, improving the recycling effect of the recycling module. On the basis of closing, multiple groups of pipes are used to suck the dust in various areas and parts, accelerating the dust recycling efficiency.

[0009] A further improvement of the technical solution of the present utility model lies in that sliding grooves opened in the processing table are symmetrically arranged on both sides of the molding groove. Extension slides are arranged in the sliding grooves, and a limiting lower die located directly below a molding and stamping device on the top of the main body of the molding machine is welded to the extension slides.

[0010] A further improvement of the technical solution of the present utility model lies in that the initial positions of the extension slides and the limiting lower die are in the processing area of the molding groove. The other end of the molding groove is a placement area, and the recycling module is arranged directly below the placement area. The recycling module needs to screen and dredge the dust blocks in the sieve plate. Therefore, during processing, the stamping of the molding machine can easily cause the sieve plate to be over-pressed and break. Therefore, during processing, the extension slides and the limiting lower die are moved into the processing area. After the processing in the processing area is completed, they are moved into the placement area. At this time, the closing plate is installed to form a closed area, avoiding the interference of movement during recycling and processing and the breakage of the mechanism.

[0011] A further improvement of the technical solution of the present utility model lies in that the recycling module includes a sieve plate located directly below the molding groove. The middle part of the sieve plate is hollow and is limitedly installed with a sealing plate. A second recovery pipe with the other end connected to the first recovery pipe is detachably connected to the sealing plate. Mesh holes are arranged in an array on the sieve plate. The first recovery pipe and the second recovery pipe in the recycling module respectively complete the recovery of the powder floating in the air and the powder falling into the sieve plate. And this premise is that the sieve plate is impacted by the cam mechanism below.

[0012] A further improvement of the technical solution of the present utility model lies in that: the recycling module further includes columns symmetrically and fixedly arranged directly below the sieve plate. A return spring is sleeved on the columns and the sieve plate, and the bottom of the columns is vertically and fixedly installed on the transverse partition. Dampers are symmetrically and fixedly installed at the bottom of the transverse partition. A drive shaft is rotatably installed at the middle part of the transverse partition, and the other end of the drive shaft is connected to a drive motor through a coupling. A cam mechanism for hitting the sieve plate is detachably connected to the drive shaft; after the cam mechanism hits the sieve plate, the powder accumulated on the sieve plate is impacted. The powder is screened by the sieve plate under the impact force, and part of it falls below the sieve plate, while part of the powder escapes into the air. The first recovery pipe and the second recovery pipe complete the separate extraction and recovery of the powder in each area, and the impact on the sieve plate can break some of the lumpy powder, improving the recovery efficiency.

[0013] A further improvement of the technical solution of the present utility model lies in that: the end of the air extraction pipeline far from the air extraction pump leads into a through rod rotatably installed in the processing table. The other end of the through rod is connected to an air extraction disc with a plurality of air extraction holes opened on its end face, and the through rod is connected to a gear two on a power shaft arranged on one side of the gear transmission through a key connection. The other end of the power shaft is connected to a servo motor through a coupling.

[0016] 1.

And the dust is enclosed in the processing table and the molding groove, improving the recovery effect of the recycling module. On the basis of the enclosure, multiple groups of pipelines are used to suck the dust in each area and each part, accelerating the dust recovery efficiency.

The first recovery pipe and the second recovery pipe complete the separate extraction and recovery of the powder in each area, and the impact on the sieve plate can break some of the lumpy powder, improving the recovery efficiency.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1-4 , the present utility model provides 3 technical solutions:

[0032] Embodiment 1:

[0033] A powder recovery device for a molding machine, including a main body 1 of the molding machine. A processing table 2 is arranged directly below the main body 1 of the molding machine. A molding groove 2-1 for processing is opened in the processing table 2. A recovery module for recovery and screening is arranged below the molding groove 2-1, and sealing modules are symmetrically arranged at the left and right ends of the molding groove 2-1;

[0034] The closed module includes magnetic suction grooves 3-1 opened on the side surfaces at both ends of the processing table 2. Inside the magnetic suction grooves 3-1, there is a closed plate 3-2 that is concave as a whole. The closed plate 3-2, the processing table 2, and the forming groove 2-1 form a closed area. On the closed plate 3-2, there is a first recovery pipe 3-5 with the other end connected to an air extraction pipe 3-3, and the other end of the air extraction pipe 3-3 is connected to an air extraction pump 3-4 fixedly installed on the side surface of the processing table 2.

[0035] In this embodiment, the magnetic suction grooves 3-1 are connected to an external magnetic induction coil assembly, and the material of the closed plate 3-2 is a permanent magnet. During processing, the magnetic suction state of the closed plate 3-2 in the magnetic suction grooves 3-1 is cancelled, and the closed plate 3-2 can be slid and disassembled to avoid affecting normal forming. After processing, through the magnetic suction fixation between the closed plate 3-2 and the magnetic suction grooves 3-1, the recovery module is closed, preventing dust from escaping during the recovery process and affecting the health of users and the processing environment. Moreover, the dust is enclosed within the processing table 2 and the forming groove 2-1, improving the recovery effect of the recovery module. On the basis of the enclosure, multiple groups of pipes are used to suck the dust in each area and at each position, accelerating the dust recovery efficiency.

[0036] On both sides of the forming groove 2-1, symmetrically arranged are sliding grooves 2-1a opened in the processing table 2. Inside the sliding grooves 2-1a, there are extension sliding plates 2-1b, and welded to the extension sliding plates 2-1b is a limiting lower die 2-1c directly below the forming stamping device 1-1 at the top of the forming machine main body 1.

[0037] The initial positions of the extension sliding plates 2-1b and the limiting lower die 2-1c are in the processing area of the forming groove 2-1. The other end of the forming groove 2-1 is the placement area, and the recovery module is arranged directly below the placement area.

[0038] On the basis of the above, the recovery module needs to screen and dredge the dust blocks in the sieve plate 4-1. Therefore, during processing, the stamping of the forming machine can easily cause the sieve plate 4-1 to be over-pressed and break. Thus, during processing, the extension sliding plates 2-1b and the limiting lower die 2-1c are moved into the processing area. After the processing in the processing area is completed, they are moved into the placement area. At this time, the closed plate 3-2 is installed to form a closed area, avoiding interference in movement and breakage of the mechanism during recovery and processing.

[0039] Embodiment 2:

[0040] On the basis of Embodiment 1: The recovery module includes a sieve plate 4-1 directly below the forming groove 2-1. The middle part of the sieve plate 4-1 is hollow and is limitedly installed with a sealing plate 4-1a. Removably connected to the sealing plate 4-1a is a second recovery pipe 4-1b with the other end connected to the first recovery pipe 3-5. The sieve plate 4-1 is arranged with mesh holes 4-1c in an array.

[0041] In this embodiment, the first recovery pipe 3-5 and the second recovery pipe 4-1b in the recovery module respectively complete the recovery of the powder floating in the air and the powder falling into the sieve plate 4-1. This is based on the premise that the sieve plate 4-1 is impacted by the cam mechanism 4-4c below.

[0042] The recovery module further includes columns 4-2 symmetrically and fixedly arranged directly below the sieve plate 4-1. A return spring 4-3 is sleeved between the columns 4-2 and the sieve plate 4-1. The bottom of the column 4-2 is vertically and fixedly installed on the cross partition 4-4. Symmetrically and fixedly installed at the bottom of the cross partition 4-4 are damping rods 4-5. At the middle part of the cross partition 4-4, a drive shaft 4-4b is rotatably installed, and the other end of the drive shaft 4-4b is connected to a cam mechanism 4-4c for impacting the sieve plate 4-1 through a coupling.

[0043] In the above, after the cam mechanism 4-4c impacts the sieve plate 4-1, the powder accumulated on the sieve plate 4-1 is impacted. The powder is screened by the sieve plate 4-1 under the impact force. Part of the powder falls below the sieve plate 4-1, and part of the powder escapes into the air. The first recovery pipe 3-5 and the second recovery pipe 4-1b complete the separate extraction and recovery of the powder in each area. Moreover, the impact on the sieve plate 4-1 can break some blocky powder, improving the recovery efficiency.

[0044] Embodiment Three:

[0045] Based on Embodiment One and Embodiment Two: One end of the air extraction pipeline 3-3 far from the air extraction pump 3-4 leads into a through rod 4-6 rotatably installed in the processing table 2. The other end of the through rod 4-6 is connected to an air extraction disc 4-6a with a number of air extraction holes opened on the end face. And the through rod 4-6 is connected to a second gear on a power shaft 4-6c arranged on one side through a key-connected gear 4-6b. The other end of the power shaft 4-6c is connected to a servo motor 4-6d through a coupling. In order to ensure that the falling dust can be fully recovered in the area below the processing table 2, the servo motor 4-6d drives the rotation of the power shaft 4-5c. Due to the meshing of the gear 4-6b, the through rod 4-6 rotates. The through rod 4-6 drives the connected air extraction disc 4-6 to rotate, thereby changing the extraction position and angle to a certain extent and improving the recovery effect.
