Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal powder forming, in particular to a metal powder forming machine for assisting classification and recycling. BACKGROUND

[0002] In some metal powder forming processes, an adhesive is used to help metal powder forming, so that the metal powder forming machine can complete the forming operation in a shorter time, improving production efficiency. When the metal powder forming machine is in use, waste materials such as overflow materials, flash materials, and unqualified products may be generated. In order to avoid waste, these waste materials need to be recycled and reused, for example;

[0003] The patent with the patent number "CN116748519B" disclosed in the prior art is named "metal powder injection molding equipment", which discloses that the outer reflux circulation guide system includes a cut-off and drainage assembly for the cut-off and drainage of the material liquid in the outer centrifugal area layer, and a reflux and drainage assembly for the reflux and circulation of the cut-off material liquid. With the push shaft, the micro bubbles in the material liquid have a tendency to centrifugally distribute outward in the radial direction. The cut-off and drainage assembly divides and cuts off the material liquid in the outer centrifugal area layer, and then the reflux and drainage assembly continuously guides the cut-off material liquid to reflux to the right end interval segment of the push shaft, so that the material liquid containing more bubbles flows into the right end side. Under the action of the negative pressure air pump, the bubbles can flow to the right side, thereby improving the density of the material liquid and the quality of the injection molding. As another example, the patent with the patent number "CN117380961B" disclosed in the prior art is named "metal powder molding machine with material separation and recycling system", which discloses that when the metal powder product is injection molded, the waste generated by injection is put into the material collecting hopper. The whole material collecting hopper is weighed by the weighing sensor, and the weight data is fed back to the controller. When the whole weight of the material collecting hopper reaches the set threshold, the controller controls the start of each component of the recycling system in the recycling area. The electric gate valve on the material hopper and the material collecting hopper is started, and the waste is introduced into the crushing cylinder. When feeding, the vibration of the material collecting hopper is started by the vibration motor to prevent the waste from being blocked in the material collecting hopper. After the waste enters the inside of the crushing cylinder, the two sets of electric gate valves are closed again. The drive motor drives the crushing shaft and the crushing blades to rotate to crush the waste. After crushing, the metering pump and the delivery solenoid valve are started. The metering pump introduces the solvent into the crushing cylinder along the delivery pipe. The solvent removes the binder on the crushed waste. Then the sewage electromagnetic valve is started to discharge the solvent mixture in the crushing cylinder. Then the electric heating fan and the two sets of air guide electromagnetic valves are started. The electric heating fan works to produce high temperature air, which is introduced into the crushing cylinder along the air intake manifold and discharged along the exhaust manifold. The crushed powder is dried by high temperature air. After drying, the discharge gate valve is started to introduce the waste into the grinding machine for grinding. The metal powder produced after grinding is recovered at the outlet of the grinding machine.

[0004] The metal powder molding machine in the above prior art needs to use a detection machine to detect whether the product is qualified before the unqualified product waste is put into the material collecting hopper by the staff. This will consume a lot of time, so it cannot automatically detect and automatically put the unqualified product waste into the material collecting hopper, which will affect the efficiency of waste crushing and classification recovery.

[0034] The crushing and recycling mechanism comprises a crushing assembly 20 installed in the classification and recycling chamber 6, a crushing lower auxiliary frame 19 is arranged on the upper outer side of the crushing assembly 20, a crushing upper auxiliary frame 18 is fixed on the upper side of the crushing lower auxiliary frame 19, the crushing upper auxiliary frame 18 and the crushing lower auxiliary frame 19 are both installed in the classification and recycling chamber 6, the crushing upper auxiliary frame 18 and the crushing lower auxiliary frame 19 are arranged in mirror image, the crushing upper auxiliary frame 18 and the crushing lower auxiliary frame 19 are both arranged in a funnel shape, the crushing assembly 20 is arranged in a conical shape, a single-rotation reciprocating screw rod 24 is threadedly connected in the bottom inner side of the crushing assembly 20, the lower end of the single-rotation reciprocating screw rod 24 is connected with a motor in the support frame body 1 through a coupling, limit columns 21 are installed on the outer side of the crushing assembly 20 at equal intervals, sliding grooves 22 are formed in the inner side walls of the classification and recycling chamber 6 at equal intervals, the limit columns 21 are slidably connected in the sliding grooves 22, the classification and recycling mechanism comprises a classification filter plate 16 arranged below the crushing assembly 20 and a guide plate 17 arranged below the classification filter plate 16, the classification filter plate 16 and the guide plate 17 are both arranged in an inclined shape, two discharge frames 15 are installed in the left inner side of the classification and recycling chamber 6, the two discharge frames 15 are respectively arranged on the left side of the classification filter plate 16 and the guide plate 17, a shielding plate 23 is arranged on the left lower side of the crushing assembly 20, the shielding plate 23 is installed in the classification and recycling chamber 6, the shielding plate 23 is arranged in an inclined shape, and the classification filter plate 16 is arranged below the shielding plate 23.

[0035] Firstly, the metal powder mixed with the adhesive is injected into the hopper 2, and then the metal powder is transported into the forming mold in the forming chamber 4 through the screw feeding mechanism 3, and then the forming operation can be carried out. This part is prior art, so it is not described in detail here. After a period of time, the forming mold in the forming chamber 4 is opened, and at this time the forming product can automatically fall into the corresponding detection frame 9 directly below through the opening in the bottom surface of the forming chamber 4 and the upper surface of the support frame body 1. At this time, through the falling of the forming product, the preliminary detection of whether the forming product is qualified can be carried out. Then the motor in the support frame body 1 is started to drive the vertical rod 7 to rotate clockwise. When the vertical rod 7 rotates, the four sets of detection frames 9 are driven to rotate by the manual telescopic rod 14. At this time, the bottom plate 5 is fixed and does not move. When the detection frame 9 at the rear side of the vertical rod 7 rotates to the right side, the protruding rod 10 at the rear side of the detection frame 9 will sequentially contact with multiple arc-shaped automatic control blocks 131. The automatic control blocks 131 will exert a pushing force on the protruding rod 10 and the detection frame 9, so that the manual telescopic rod 14 corresponding to the detection frame 9 is retracted, and the reset spring 141 is charged. Through repeated operation, the detection frame 9 can drive the internal forming product to reciprocate horizontally, so as to detect whether the forming product is qualified. After the detection is completed, when the right side detection frame 9 rotates to the front side, the workers can watch whether the forming product in the detection frame 9 is broken by eyes, or can watch through the camera. When the forming product in the detection frame 9 is not broken, the workers can manually or through the mechanical hand to take out the forming product in the detection frame 9. When the forming product in the detection frame 9 is broken, the detection frame 9 is continuously rotated, so that the front side detection frame 9 rotates to the left side of the vertical rod 7. At this time, the left side detection frame 9 rotates to coincide with the through slot 51, and then the unqualified product waste in the left side detection frame 9 falls into the classification recovery chamber 6 through the through slot 51, the discharging frame 52 and the second feeding port 62. Therefore, the unqualified product waste can be automatically assisted to be recovered.

[0036] Then other waste materials can also be put into the classified recycling chamber 6 through the first feeding port 61, and then the unqualified product waste materials and other waste materials fall between the crushing upper auxiliary frame 18 and the crushing assembly 20 through the crushing lower auxiliary frame 19. The motor in the support frame body 1 is started to drive the single-rotation reciprocating screw rod 24 to rotate. When the single-rotation reciprocating screw rod 24 rotates, the crushing assembly 20 connected with the outer side of the single-rotation reciprocating screw rod 24 through threads rotates up and down. At this time, the limiting column 21 on the outer side of the crushing assembly 20 slides in the sliding groove 22, so as to ensure the stable up-and-down reciprocating lifting of the crushing assembly 20. At this time, the crushing assembly 20 cooperates with the crushing lower auxiliary frame 19 to crush the unqualified product waste materials and other waste materials. Part of the crushed waste materials directly falls on the inclined classified filtering plate 16 for filtering and classification. Another part of the crushed waste materials is guided to fall on the classified filtering plate 16 for filtering and classification through the inclined shielding plate 23. The setting of the shielding plate 23 can avoid another part of the crushed waste materials from falling on the upper discharging frame 15. Then the small-particle waste materials after crushing fall on the guide plate 17 through the classified filtering plate 16 for collection. The large-particle waste materials after crushing are left on the classified filtering plate 16 for collection. In the later period, the corresponding discharging frame 15 can be opened to discharge the classified and recycled waste materials for reuse.

[0037] In the crushing process, the classified recycling chamber 6 is heated by the heating wire in the heating assembly 8. When the decomposition or volatilization temperature of the adhesive is reached, it is maintained for a period of time. Then the adhesive in the waste materials in the classified recycling chamber 6 can be decomposed and volatilized through heating, so as to remove the adhesive in the metal waste materials, forming a non-toxic, harmless and non-flammable and explosive gas or steam. In the later period, the connecting pipe 11 can be connected with an air pump outside to collect the volatilized adhesive in the classified recycling chamber 6. Since this part is prior art, it will not be described in detail here.

[0038] In the classified recycling chamber 6, the classified recycling chamber 6 is heated by the heating wire in the heating assembly 8. When the decomposition or volatilization temperature of the adhesive is reached, it is maintained for a period of time. Then the adhesive in the waste materials in the classified recycling chamber 6 can be decomposed and volatilized through heating, so as to remove the adhesive in the metal waste materials, forming a non-toxic, harmless and non-flammable and explosive gas or steam. In the later period, the connecting pipe 11 can be connected with an air pump outside to collect the volatilized adhesive in the classified recycling chamber 6. Since this part is prior art, it will not be described in detail here. Figures 8-10As shown, the upper inside of the shielding plate 23 is fixed with a rotating rod 25, the rotating rod 25 is rotatably connected with the inside of the classified recycling chamber 6, the middle part of the rotating rod 25 is wound with a control rope 26, the front end of the rotating rod 25 is nested with a vortex spring 27, one end of the vortex spring 27 is connected with the inside of the classified recycling chamber 6, the upper end of the control rope 26 is connected with the left limiting column 21 through the left side wall of the classified recycling chamber 6, on the basis of the first embodiment, when the left limiting column 21 rises, the left limiting column 21 will pull one end of the control rope 26, then the control rope 26 automatically drives the rotating rod 25 and the shielding plate 23 to rotate, at this time the vortex spring 27 stores energy, when the left limiting column 21 descends, at this time the energy stored by the vortex spring 27 can automatically drive the rotating rod 25 and the shielding plate 23 to rotate reversely and reset, thereby the shielding plate 23 reciprocating swings, so that the shielding plate 23 can scatter the part of the broken waste falling on the shielding plate 23 to other positions on the classified filtering plate 16, avoiding the waste being accumulated on the fixed position on the classified filtering plate 16 to affect the later filtering work.

[0039] Although the present application has been described in detail with reference to the foregoing embodiments, technical solutions recorded in the foregoing embodiments can be modified or some technical features can be replaced by equivalent ones by those skilled in the art, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
