[0002] Die casting technology is a common metal casting method. The main principle is to melt the metal into liquid through a boiler, and then inject the liquid metal into the mold through an injection system. When the liquid metal cools, it forms a product in the mold cavity. After the mold is opened, the product is taken out and processed for secondary processing to finally form a finished product. There are still certain problems in the current hot chamber die casting equipment: hot chamber die casting equipment often processes small workpieces with high melting points. Its processing speed is fast, so the loss of metal raw materials is also large, and it is necessary to continuously add metal raw materials to the boiler. The current metal raw materials are long strips. In the prior art, when adding raw materials, the metal raw materials are often inserted into the feed port of the boiler. Due to the high melting point of such raw materials, it takes a long time to completely melt the raw materials. It is easy to fail to keep up with the processing speed, affecting the processing efficiency, resulting in a decrease in the liquid level in the boiler, and then causing slag to block the injection pipeline and other conditions.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a smelting die-casting equipment and a ferrous metal forming method based on hot chamber die-casting.

[0021] Example 1: Please refer to Figure 1-Figure 3 , a smelting die-casting equipment, comprising a main body 1 and a boiler 2 installed on the main body 1, a feed port 3 is arranged on the top of the boiler 2, a feeding assembly 4, an upper clamping assembly 5, a lower clamping assembly 6, a heating assembly 7 and a cutting assembly 8 are also arranged on the top of the boiler 2; The feeding assembly 4 includes a guide rail 41 with one end extending to the top of the feed port 3, and the feeding assembly 4 is used to drive the raw material to move to the top of the feed port 3; The upper clamping assembly 5 includes a clamp 50 that can move vertically. The clamp 50 is located directly above the feed port 3. The upper clamping assembly 5 is used to clamp the raw material and drive the raw material to move toward the feed port 3. The cutting assembly 8 includes a plasma gun head 81, which is located at the bottom of the fixture 50, and the plasma gun head 81 is arranged toward the area above the feed port 3. The cutting assembly 8 is used to cut the raw material; The heating component 7 includes an electromagnetic coil 71, and the electromagnetic coil 71 is located below the plasma gun head 81. The heating component 7 is used to heat the raw material; The lower clamping assembly 6 includes two groups of movable clamping rollers 601, and the two groups of clamping rollers 601 are located at the bottom of the electromagnetic coil 71. The lower clamping assembly 6 is used to clamp the raw material and drive the raw material to move downward into the feed port 3; The loading component 4 operates to move the raw material to the top of the feed port 3, the upper clamping component 5 operates, clamps the top of the raw material through the clamp 50 and drives the raw material to move downward, the cutting component 8 and the heating component 7 operate during the downward movement of the raw material, the cutting component 8 cuts the raw material through the plasma gun head 81 when it is operating, and the heating component 7 preheats the raw material through the electromagnetic coil 71 when it is operating, then the lower clamping component 6 clamps the bottom of the raw material, and at the same time the upper clamping component 5 releases the top of the raw material, and finally the lower clamping component 6 drives the raw material to move downward, so that the cut and preheated raw material slowly enters the feed port 3.

[0022] The shape of the top of the raw material used in this practical example matches the guide rail 41, and can be slidably mounted on the guide rail 41 before use. A plurality of raw materials are evenly arranged in a vertical state, wherein the raw material at the end of the guide rail 41 is just located directly above the feed port 3, the central axis of the electromagnetic coil 71 coincides with the central axis of the feed port 3, and the inner diameter of the electromagnetic coil 71 is greater than the width of the raw material; When in use, the raw material is first assembled onto the guide rail 41, and then the loading assembly 4 is started when the raw material needs to be added to the boiler 2. The operation of the loading assembly 4 forces the raw material to move to one end of the guide rail 41, so that the raw material is just above the feed port 3, and then the upper clamping assembly 5 is started. When the upper clamping assembly 5 is in operation, the raw material is first clamped by the clamp 50, and then the raw material is moved downward, so that the raw material gradually approaches the feed port. At the same time, the cutting assembly 8 and the heating assembly 7 are started. When the cutting assembly 8 is in operation, the plasma gun head 81 works, and the raw material just passes through the plasma gun head 81 when it moves downward, thereby cutting the raw material. When the heating assembly 7 is in operation, heat is generated inside the electromagnetic coil 71, which is When the cut raw material continues to move downward, it just passes through the electromagnetic coil 71 to achieve preheating. Then, when the raw material is about to be cut, the bottom end of the raw material just moves between the two clamping rollers 601. At this time, the lower clamping assembly 6 is started, forcing the two clamping rollers 601 to move and clamp the raw material. At this time, the upper clamping assembly 5 operates to force the clamp 50 to loosen the top of the raw material. Then, the lower clamping assembly 6 continues to operate to force the two clamping rollers 601 to rotate at the same time. When the two clamping rollers 601 rotate, the raw material is driven to continue to move downward, so that the raw material is completely cut into multiple pieces and preheated. Then, the raw material moves downward and slowly inserts into the feed port 3. The cut and preheated raw material melts faster in the boiler 2. By arranging a feeding assembly 4, an upper clamping assembly 5, a lower clamping assembly 6, a heating assembly 7 and a cutting assembly 8 at the feed port 3 of the boiler 2, it is possible to realize automatic feeding of metal raw materials, thereby reducing the workload. In addition, the raw materials can be cut and preheated before feeding, and after being cut into multiple thinner and high-temperature raw materials, they enter the boiler 2. At this time, the raw materials are more easily heated to the melting point, which increases the melting speed, thereby meeting high-speed smelting and casting work, ensuring production efficiency, and avoiding a series of adverse effects caused by the slow melting speed of the raw materials.

[0023] Example 2: See Figure 3 and Figure 4 , different from the above embodiment, a fixed protrusion 42 and a movable protrusion 43 are provided at the bottom of the guide rail 41, and the movable protrusion 43 has the same shape as the fixed protrusion 42. The movable protrusion 43 is located directly above the feed port 3 and is slidably connected to the bottom of the guide rail 41. A horizontal cylinder 44 is fixed to the top of the guide rail 41, and a connecting frame 45 is fixedly connected to the output end of the horizontal cylinder 44. The connecting frame 45 is fixedly connected to the movable protrusion 43, and a positioning block 46 is also provided on the edge of the movable protrusion 43. The feeding assembly 4 also includes a bracket 47 fixed to the top of the boiler 2, and the guide rail 41 is fixedly connected to the bracket 47. A transverse slide 48 parallel to the guide rail 41 is also fixed on the bracket 47, and a transverse slide 49 is provided on the transverse slide 48. A push plate 40 is fixed on the transverse slide 49, and the push plate 40 extends to the bottom of the guide rail 41.

[0024] In actual application, a groove matching the shape of the fixed protrusion 42 or the movable protrusion 43 is provided at the top of the raw material, and the raw material slides on the fixed protrusion 42 or the movable protrusion 43 through the groove, the output direction of the horizontal cylinder 44 is consistent with the direction of the guide rail 41, and the horizontal slide 48 is set as an electric slide; When in use, first start the transverse slide 48. When the transverse slide 48 is running, the transverse slide 49 and the push plate 40 move, and the push plate 40 pushes the raw materials, so that all the raw materials slide along the guide rail 41, and the raw materials closest to the end of the guide rail 41 slide onto the movable protrusion 43 until they contact the positioning block 46. At this time, the raw material is just above the feed port 3 and is still in the clamp 50. When the upper clamping assembly 5 is running, the clamp 50 clamps the top of the raw material. At this time, the horizontal cylinder 44 is started. When the horizontal cylinder 44 is extended, it drives the connecting frame 45 to move. The connecting frame 45 drives the movable protrusion 43 to slide, so that the movable protrusion 43 is separated from the raw material, and then the clamp 50 can move the raw material vertically; By providing the feeding assembly 4, it is advantageous to drive the automatic feeding of raw materials through the horizontal cylinder 44 and the transverse slide 48, without manual feeding, with a high degree of automation and reduced workload.

[0025] Example 3, see Figure 7-10 , different from the above embodiment, the upper clamping assembly 5 includes a vertical slide 501, a vertical slide seat 502 is arranged on the vertical slide 501, an extension rod 503 is fixed on one side of the vertical slide seat 502, the clamp 50 is fixed to the end of the extension rod 503, the clamp 50 includes an upper slide rail 504, the upper slide rail 504 is fixedly connected to the end of the extension rod 503, an upper motor 505 is fixed to the end of the upper slide rail 504, an upper bidirectional screw 506 is fixed to the output shaft of the upper motor 505, the upper bidirectional screw 506 is located inside the upper slide rail 504 and both ends are rotatably connected to the upper slide rail 504, two upper sliders 507 are slidably connected in the upper slide rail 504, the two upper sliders 507 are both threadedly connected to the upper bidirectional screw 506, and a clamp 508 is fixed to the two upper sliders 507.

[0026] The upper slide rail 504 is arranged horizontally, the upper bidirectional screw rod 506 is provided with two symmetrical threads with opposite rotation directions on its surface, the two upper sliders 507 are matched with the two threads respectively, and the vertical slide table 501 is arranged as an electric slide table; When in use, when the raw material moves to the top of the feed port 3, the raw material is just located between the two clamping plates 508, and the upper motor 505 is started at this time. The upper motor 505 drives the upper bidirectional screw 506 to rotate, and the upper bidirectional screw 506 drives the two upper sliders 507 to move simultaneously and approach each other when rotating, thereby driving the clamping plates 508 to move and clamp the top of the raw material. After that, when the vertical slide 501 is started, the vertical slide seat 502 moves downward, thereby driving the entire clamp 50 and the raw material to move vertically downward; The upper clamping assembly 5 is provided to facilitate clamping the raw material and moving the raw material to the feed port 3, thereby facilitating accurate transportation of the raw material and making mechanical transportation safer.

[0027] Example 4, see Figure 7-10 , different from the above embodiment, the cutting assembly 8 also includes a plasma cutting machine chassis 82 and a vertical rod 83 fixed on the top of the boiler 2, the plasma gun head 81 is connected to the plasma cutting machine chassis 82, an angle iron 84 is fixed to the middle of the vertical rod 83, the plasma gun head 81 is fixedly mounted on the angle iron 84, a button switch 811 is provided on the plasma gun head 81, a base block 812 is fixed on the surface of the button switch 811, and chamfers 813 are provided at both ends of the base block 812.

[0028] The structures of the plasma cutting machine chassis 82 and the plasma gun head 81 are both prior art. When in use, the button switch 811 can be controlled by pressing the base block 812, thereby starting the plasma gun head 81, and the plasma gun head 81 is aimed at the vertically moving raw material to cut the raw material. By setting up a plasma cutting method for raw materials, the cutting is efficient and easy to operate. After the raw materials are cut, the heating area of ​​the raw materials in the boiler 2 is increased, and it is easier to melt quickly to meet the needs of high-speed production.

[0029] Example 5, see Figure 3 Different from the above embodiment, the heating component 7 also includes an electromagnetic controller 72 fixed on the top of the boiler 2 , and the electromagnetic coil 71 is fixed on the electromagnetic controller 72 .

[0030] Among them, the electromagnetic controller 72 and the electromagnetic coil 71 are both existing technologies. When in use, the electromagnetic controller 72 is started, and the raw materials are quickly heated when passing through the electromagnetic coil 71, thereby realizing the preheating work of the raw materials before entering the boiler 2. The preheated raw materials heat up faster in the boiler 2 and are easier to melt.

[0031] Example 6, see Figure 5 and Figure 6, which is different from the above embodiment, the lower clamping assembly 6 includes a lower sliding rail 602 fixed on the top of the boiler 2, a lower motor 603 is fixed at the end of the lower sliding rail 602, a lower bidirectional screw 604 is fixed to the output shaft of the lower motor 603, the lower bidirectional screw 604 is located inside the lower sliding rail 602 and is rotatably connected to the lower sliding rail 602 at both ends, two lower sliders 605 are slidably connected inside the lower sliding rail 602, the two lower sliders 605 are both threadedly connected to the lower bidirectional screw 604, the two lower sliders 605 are fixedly connected to an assembly frame 606, the two assembly frames 606 are symmetrically distributed, and the two clamping rollers 601 are respectively arranged on the two assembly frames 606, The clamping roller 601 is rotatably connected to the assembly frame 606 via a rotating shaft 607, a worm wheel 608 is fixedly connected to the end of the rotating shaft 607, a worm 609 is meshed with the edge of the worm wheel 608, the worm 609 is installed on the assembly frame 606 via two first bearing seats 610, a square hole 611 is opened at the end of the worm 609, a driving motor 612 is also fixedly connected to the lower slide rail 602, a square rod 613 is fixed to the output shaft of the driving motor 612, the square rod 613 and the square holes 611 on the two worms 609 are movably plugged, and two second bearing seats 614 are also installed on the square rod 613, and the two second bearing seats 614 are fixed on the lower slide rail 602; The lower rail 602 is horizontally arranged, the lower bidirectional screw rod 604 is provided with two symmetrically arranged threads with opposite rotation directions, the two lower sliders 605 are matched with the two threads respectively, the main body 1 of the square rod 613 has a square cross section, and the cross section of the connection part between the square rod 613 and the second bearing seat 614 is circular; When in use, the lower motor 603 is started, and the lower bidirectional screw 604 is driven to rotate when the lower motor 603 is running. When the lower bidirectional screw 604 rotates, it drives the two lower sliders 605 to approach each other, thereby driving the two assembly frames 606, the clamping rollers 601 on the assembly frame 606 and other parts to move. When the worm 609 on the assembly frame 606 moves, it just slides along the square rod 613. Finally, the two clamping rollers 601 clamp the raw material. Due to the self-locking characteristics of the worm gear 608 and the worm 609, the clamping rollers 601 will not rotate at will, ensuring the clamping effect. After the raw material is clamped, the driving motor 612 is started. After the driving motor 612 is running, it drives the square rod 613 to rotate. When the square rod 613 rotates, it drives the worm 609 on the two assembly frames 606 to rotate. When the worm 609 rotates, it drives the worm gear 608 to rotate. When the worm gear 608 rotates, it drives the rotating shaft 607 and the clamping roller 601 to rotate. When the two clamping rollers 601 rotate at the same time, the raw material is driven to slowly insert into the feed port 3; By setting up the lower clamping assembly 6, the raw material that is about to be cut can be clamped first, and then the raw material can be slowly inserted into the feed port 3, which not only ensures that the raw material is completely cut and heated, but also allows the cut raw material to enter the boiler 2 at a slower speed, preventing the raw material from falling into the boiler 2 quickly and damaging the boiler 2.

A fourth bevel gear 23 is fixed to the end of the transmission bidirectional screw 10, and the fourth bevel gear 23 is meshed with the third bevel gear 22; In the initial state, the transmission gear 17 is located at the top of the rack 13 and is just meshed with the rack 13, the two round pins 12 are respectively located on both sides of the plurality of base blocks 812, the transmission bidirectional screw 10 is provided with two symmetrically distributed and oppositely rotating threads, and the two transmission sliders 11 are matched with the two threads respectively; When in use, the clamp 50 is in operation, the splint 508 moves, the splint 508 moves, the rack 13 moves, the rack 13 moves, the transmission gear 17 rotates, the transmission gear 17 rotates, the base shaft 15 and the first bevel gear 18 rotate, the first bevel gear 18 rotates, the second bevel gear 21, the transmission shaft 19 and the third bevel gear 22 rotate, the third bevel gear 22 rotates, the fourth bevel gear 23 rotates, the transmission bidirectional screw 10 rotates, the bidirectional screw rotates, and the two transmission sliders 11 are driven to approach each other at the same time when the bidirectional screw rotates, thereby driving the two round pins 12 to approach each other. The two round pins 12 will touch each other during the movement. The chamfer 813 at the end of the contact base block 812 is pressed, and the base block 812 and the button switch 811 are pressed, so that the corresponding plasma gun head 81 is started. In application, for narrower raw materials, the spacing of the clamping plate 508 is larger, and the distance of the round pin 12 is larger, so that the two round pins 12 are moved to the same base block 812 in the middle. At this time, only the plasma gun head 81 in the middle is started to cut the raw material into two pieces. On the contrary, the spacing of the clamping plate 508 is smaller, and the distance of the round pin 12 is smaller. The two round pins 12 are respectively moved to the two base blocks 812 on both sides. At this time, the plasma gun heads 81 of the chains on both sides operate simultaneously to cut the raw material into three pieces. By providing a round pin 12 that can move with the clamp 508, the clamp 508 also plays the function of measuring the width of the raw material when clamping the raw material, and then adaptively adjusting the position of the round pin 12. When the raw material is thicker, the position of the round pin 12 can just activate the two outer plasma gun heads 81, thereby dividing the raw material into three pieces. When the raw material is thinner, the position of the round pin 12 only activates the middle plasma gun head 81, thereby dividing the raw material into two pieces, which has higher applicability.
