The upsetting machine mainly consists of a machine body, a punch assembly, a large slide block drive mechanism, a main die, an ejector mechanism, a feeding mechanism, and a shearing mechanism.

[0003] In existing technologies, various furniture screw connecting rods, double-headed pedestal nails, double-headed ball nails, double-headed semi-circular nails, flanges with blind holes at both ends, cross-shaped nails at both ends, and hexagonal nails at both ends are required. These products require the ends to be larger than the middle, resulting in unstable forming. After mold closing and upsetting, the material cannot be naturally removed, increasing resource consumption and making them inconvenient to use. Summary of the Invention

[0015] In one possible design, the right mold ejection assembly includes two second grooves formed inside the right mold. Two second connecting posts are fixed to the side ends of the first cover plate. A second extrusion rod is fixed to the side ends of each of the two second connecting posts. The two second extrusion rods are respectively disposed in the two second grooves. A fourth spring is fixed to the side ends of each of the two second connecting posts. The two fourth springs are respectively fixed in the two second grooves. The two fourth springs are respectively sleeved in the two second extrusion rods. The two second extrusion rods move outward and penetrate into the left mold groove.

[0016] In one possible design, the left mold ejection assembly includes a first U-shaped seat fixed to the machine body, a jump rod rotatably mounted within the first U-shaped seat, a first roller rotatably mounted at one end of the jump rod, a cam fixed to the surface of the rotating shaft, the first roller rotating on the surface of the cam, a first spherical sleeve fixed to the other end of the jump rod, a first connecting rod slidably mounted within a second cover plate, a first ball joint fixed to the side end of the first connecting rod, a first spring fixed between the first ball joint and the second cover plate, the first spring sleeved on the surface of the first connecting rod, an elliptical groove formed within the left mold, and a sliding column slidably mounted within the elliptical groove.

[0018] In one possible design, the bottom end of the second cover plate is fixed with a baffle plate that matches the material discharge chute.

[0019] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0020] A method for using a die-fitting upsetting device that facilitates material discharge includes the following steps:

[0021] S1. The rotation of the shaft drives the turntable to rotate. The second roller inside the connecting block approaches the convex surface of the turntable. The convex surface of the turntable presses the second roller and the connecting block to move away from the shaft. The connecting block presses and pushes the second ball head rod through the second connecting rod. The second ball head rod drives one end of the pressure rod to move away from the shaft. Since the pressure rod rotates inside the second U-shaped frame, one end of the pressure rod moves away from the shaft. The other end of the pressure rod with the adjusting bolt moves towards the shaft. The adjusting bolt pushes the cone head. The cone head pushes the right mold to fit with the left mold through the ejector pin to close the mold. At this time, the convex part of the cam and the first roller do not contact each other.

[0022] S2. The second roller inside the connecting block approaches the notch in the turntable. The elasticity of the second spring pushes the connecting block to fit the notch, causing one end of the pressure rod to move towards the direction closer to the rotating shaft. The pressure rod drives the other end of the adjusting bolt to move away from the rotating shaft. The adjusting bolt loses its pressure on the cone head. The elasticity of the disc spring pushes the cone head to reset. The cone head drives the right mold to reset through the ejector pin. After the right mold resets, since the position of the second extrusion rod remains unchanged, the reset second extrusion rod enters the left mold groove inside the right mold. The material can be removed through the second extrusion rod.

[0023] S3. As the second roller in the connecting block approaches the notch in the turntable, the cam protrusion simultaneously squeezes the first roller. The cam protrusion squeezes the first roller upward, causing one end of the jump rod to move upward. Since the jump rod rotates in the first U-shaped seat, one end of the jump rod rises, and the end of the jump rod with the first ball sleeve moves downward. The downward movement of the first ball sleeve causes the first ball head rod to move downward, and the downward movement of the first ball head rod causes the first connecting rod to move downward. The first connecting rod moves downward into the right mold, squeezing the slide column located in the elliptical slide groove. The slide column is squeezed and moves towards the right mold. The slide column pushes the two first extrusion rods into the right mold groove through the two first connecting columns to remove the material.

[0024] This invention features a convenient, stable, and easy-to-repair device that protects the machine body from breakage, prevents the clamping ejector pins from breaking, protects the left and right molds from bursting, protects the pressure rods from breaking, and protects all linkage mechanisms from damage or breakage. It also automatically stops power-off in case of misalignment during clamping, thus ensuring reduced waste in the upsetting head shape.

[0025] This invention involves the upsetting and forging of various furniture screw connecting rods, double-ended studs, double-ended spherical studs, double-ended semi-circular studs, flanges with blind holes at both ends, upsetting and forging of cross-shaped and hexagonal ends at both ends, and products requiring larger ends than the middle. Not only is the forming stable, but the mold-closing upsetting structure also allows for easy material removal, consumes less power, reduces space requirements, is easy to maintain, has low fixed costs, and high efficiency, all of which can be achieved with this equipment. The mold-closing limit and opening mechanism ensures smooth upsetting and forging, which is highly beneficial for the production of furniture connecting rods. Attached Figure Description

The directional terms mentioned in the embodiments of the present invention, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0040] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0041] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0042] References to "one embodiment" or "some embodiments" as used in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the invention. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0043] Example 1

[0044] Reference Figures 1-10 A mold-closing forging device for easy material discharge includes a machine body and a rotating shaft 1 that rotates inside the machine body. Both ends of the rotating shaft 1 are fixed with bevel gears 2 for transmission.

[0045] The mold base includes a right mold 21, a left mold 22, a first cover plate 23, a second cover plate 24, and a third cover plate 25. The second cover plate 24 has a third convex positioning groove 31. The side end of the first cover plate 23 is fixed with a third convex positioning block 30 that matches the third convex positioning groove 31. The top ends of the right mold 21 and the left mold 22 are both provided with second convex positioning grooves 28. The bottom ends of the right mold 21 and the left mold 22 are both provided with first convex positioning grooves 27. The end of the third cover plate 25 near the right mold 21 is fixed with a first convex positioning block 26 that matches the two first convex positioning grooves 27. The end of the second cover plate 24 near the right mold 21 is fixed with a second convex positioning block 29 that matches the two second convex positioning grooves 28. The mold base is fixed to the machine body.

[0046] The second cover plate 24 has a material drop groove 36 in the center and a baffle plate 39. The baffle plate 39 has a screw hole that matches the front of the inclined groove of the material drop groove 36. This screw hole is used to install and fix the baffle plate.

[0047] It is particularly beneficial for processing, as the material does not bounce out to the front, the material is dropped smoothly, with high precision and strong stability;

[0048] It is easy to remove the cover, easy to change the mold, easy to install the mold, and can fix the left mold. At the same time, the mold will not swing back and forth, which greatly improves the clamping requirements for opening and closing.

[0049] After rotating until the pressure rod 17 and the mold base are balanced, unscrew the top cover screws to remove the third cover plate 25, install the right mold 21 and the left mold 22. The right mold 21 is installed on the right side inside the second cover plate 24. Then tighten the hex screws. The left mold is lowered to the left side of the second cover plate 24. Lower the top cover and tighten the screws to complete the installation and mold replacement operation.

[0050] Convenient, stable, easy to repair, protects the machine body from breakage, protects the clamping ejector pin 35 from breaking, protects the left and right molds from bursting, protects the pressure rod 17 from breaking, protects all linkage mechanisms from damage and breakage, and stops and cuts off the power at the same time if there is misalignment in clamping, which can ensure that the upsetting head shape reduces scrap.

[0051] Left mold groove 37 and right mold groove 38 are respectively opened in right mold 21 and left mold 22 to accommodate the items to be upset forged;

[0052] The device needs to be installed and fixed in existing mechanical equipment for use;

[0053] A die-closing forging device further includes a die-closing assembly, which is disposed between a rotating shaft 1 and a die base for driving the right die 21 and the left die 22 to close. The die-closing assembly includes a fixed plate fixed to the machine body, a second connecting rod 14 sliding inside the fixed plate, a connecting block 13 fixed to the side end of the second connecting rod 14, a second spring 15 fixed between the connecting block 13 and the fixed plate, the second spring 15 being sleeved on the surface of the second connecting rod 14, a turntable 11 fixed to the surface of the rotating shaft 1, a notch 12 being formed on the surface of the turntable 11, the connecting block 13 contacting the turntable 11 and the notch 12 respectively, a second U-shaped frame 16 fixed to the machine body, a pressure rod 17 rotating inside the second U-shaped frame 16, a second ball head rod 18 fixed to one end of the pressure rod 17, the protrusion of the second ball head rod 18 matching the recess of the second connecting rod 14. The other end of the pressure rod 17 is threaded with an adjusting bolt 19. A pin 35 slides inside the first cover plate 23. A cone 20 is fixed to the surface of the pin 35. The cone 20 contacts the side end of the adjusting bolt 19. A disc spring 40 is fixed to the side end of the first cover plate 23. The side end of the disc spring 40 is fixed inside the cone 20, and the cone 20 is sleeved on the surface of the disc spring 40. The rotation of the rotating shaft 1 drives the turntable 11 to rotate. The second roller 32 in the connecting block 13 approaches the convex surface of the turntable 11. The convex surface of the turntable 11 presses the second roller 32 and the connecting block 13 away from the rotating shaft 1. The connecting block 13 moves in the direction of the second ball joint rod 18 through the second connecting rod 14. The second ball joint rod 18 drives one end of the pressure rod 17 to move away from the rotating shaft 1. Since the pressure rod 17 rotates inside the second U-shaped frame 16, one end of the pressure rod 17 moves away from the rotating shaft 1, and the other end of the pressure rod 17 with the adjusting bolt 19 moves towards the rotating shaft 1. The adjusting bolt 19 pushes the cone head 20, and the cone head 20 pushes the right mold 21 to fit the left mold 22 through the ejector pin 35 to close the mold. At this time, the protrusion of the cam 3 and the first roller 6 do not contact each other.

[0054] A die-clamping forging device further includes a right die ejection assembly used in conjunction with the die-clamping assembly. The right die ejection assembly is located between the rotating shaft 1 and the die assembly and is used to eject the forged material from the left die groove 37. The right die ejection assembly includes two second grooves 48 formed in the right die 21. Two second connecting posts 46 are fixed to the side ends of the first cover plate 23. A second extrusion rod 49 is fixed to the side ends of each of the two second connecting posts 46. The two second extrusion rods 49 are respectively located in the two second grooves 48. A fourth spring 50 is fixed to the side ends of each of the two second connecting posts 46. The two fourth springs 50 are respectively fixed in the two second grooves 48 and respectively sleeved in the two second extrusion rods 49. Both second extrusion rods 49 extend outwards and penetrate into the left die groove 37. The second roller 32 inside the connecting block 13 approaches the notch 12 inside the turntable 11. The elasticity of the second spring 15 pushes the connecting block 13 to fit into the notch 12, causing one end of the pressure rod 17 to move towards the direction closer to the rotating shaft 1. The pressure rod 17 drives the other end of the adjusting bolt 19 to move away from the rotating shaft 1. The adjusting bolt 19 loses its pressure on the cone 20. The elasticity of the disc spring 40 pushes the cone 20 to reset. The cone 20 drives the right mold 21 to reset through the ejector pin 35. After the right mold 21 is reset, since the position of the second extrusion rod 49 remains unchanged, the reset second extrusion rod 49 enters the left mold groove 37 inside the right mold 21, and can be used for material removal.

[0055] Example 2

[0056] Reference Figures 1-10An improvement on Embodiment 1: A die-jointing forging device further includes a left die ejection assembly, which is located between the rotating shaft 1 and the die base to drive the forged material in the right die groove 38 to eject. The left die ejection assembly includes a first U-shaped seat 4 fixed to the machine body, a jump rod 5 rotatably mounted inside the first U-shaped seat 4, a first roller 6 rotatably mounted at one end of the jump rod 5, a cam 3 fixed to the surface of the rotating shaft 1, the first roller 6 rotating on the surface of the cam 3, a first spherical sleeve rod 7 fixed to the other end of the jump rod 5, a first connecting rod 9 slidingly mounted inside the second cover plate 24, and a first connecting rod 9 fixed to the side end of the first connecting rod 9. A ball-end rod 8 is provided. A first spring 10 is fixed between the first ball-end rod 8 and the second cover plate 24. The first spring 10 is sleeved on the surface of the first connecting rod 9. An elliptical groove 33 is provided in the left mold 22. A sliding column 34 slides in the elliptical groove 33. The first connecting rod 9 moves downward and passes through the elliptical groove 33. The inclined surface of the first connecting rod 9 contacts the surface of the sliding column 34. Two first grooves 47 are provided in the left mold 22 and communicate with the elliptical groove 33. Two first connecting columns 43 are fixed on the surface of the sliding column 34. A first extrusion rod 4 is fixed to the side end of each of the two first connecting columns 43. 4. Two first extrusion rods 44 are respectively located in two first grooves 47. Both first extrusion rods 44 move outward and penetrate into the right mold groove 38. The side ends of the two first connecting columns 43 are each fixed with a third spring 45. The two third springs 45 are respectively fixed in the two first grooves 47 and respectively sleeved on the surface of the two first extrusion rods 44. When the second roller 32 in the connecting block 13 approaches the notch 12 in the turntable 11, the protrusion of the cam 3 simultaneously presses the first roller 6. The protrusion of the cam 3 presses the first roller 6 upward, causing one end of the jump rod 5 to move towards As the lever 5 rotates within the first U-shaped seat 4, one end of the lever 5 rises, while the end of the lever 5 with the first spherical sleeve 7 moves downward. The downward movement of the first spherical sleeve 7 causes the first ball head rod 8 to move downward, which in turn causes the first connecting rod 9 to move downward. The first connecting rod 9 moves downward into the right mold 21, pressing the sliding column 34 located in the elliptical groove 33. The sliding column 34 is pressed and moves towards the right mold 21. The sliding column 34 pushes the two first extrusion rods 44 into the right mold groove 38 through the two first connecting columns 43 for material removal.

[0057] A method for using a die-fitting upsetting device that facilitates material discharge includes the following steps:

[0058] S1. The rotation of the rotating shaft 1 drives the rotating disk 11 to rotate. The second roller 32 in the connecting block 13 approaches the convex surface of the rotating disk 11. The convex surface of the rotating disk 11 presses the second roller 32 and the connecting block 13 to move away from the rotating shaft 1. The connecting block 13 presses and pushes the second ball head rod 18 through the second connecting rod 14. The second ball head rod 18 drives one end of the pressure rod 17 to move away from the rotating shaft 1. Since the pressure rod 17 rotates in the second U-shaped frame 16, one end of the pressure rod 17 moves away from the rotating shaft 1. The other end of the pressure rod 17 with the adjusting bolt 19 moves towards the rotating shaft 1. The adjusting bolt 19 pushes the cone head 20. The cone head 20 pushes the right mold 21 to fit the left mold 22 through the ejector pin 35 to close the mold. At this time, the convex part of the cam 3 and the first roller 6 do not contact each other.

[0059] S2. The second roller 32 in the connecting block 13 approaches the notch 12 in the turntable 11. The elasticity of the second spring 15 pushes the connecting block 13 to fit the notch 12, causing one end of the pressure rod 17 to move towards the direction close to the rotating shaft 1. The pressure rod 17 drives the other end of the adjusting bolt 19 to move away from the rotating shaft 1. The adjusting bolt 19 loses its pressure on the cone 20. The elasticity of the disc spring 40 pushes the cone 20 to reset. The cone 20 drives the right mold 21 to reset through the ejector pin 35. After the right mold 21 is reset, since the position of the second extrusion rod 49 remains unchanged, the second extrusion rod 49 enters the left mold groove 37 in the right mold 21 and can be used for material removal.

[0060] S3. As the second roller 32 in the connecting block 13 approaches the notch 12 in the turntable 11, the protrusion of the cam 3 simultaneously presses the first roller 6. The protrusion of the cam 3 presses the first roller 6 upward, causing one end of the jump rod 5 to move upward. Since the jump rod 5 rotates in the first U-shaped seat 4, one end of the jump rod 5 rises, and the end of the jump rod 5 with the first ball sleeve 7 moves downward. The downward movement of the first ball sleeve 7 causes the first ball head rod 8 to move downward. The downward movement of the first ball head rod 8 causes the first connecting rod 9 to move downward. The first connecting rod 9 moves downward into the right mold 21, pressing the slide column 34 located in the elliptical slide groove 33. The slide column 34 is pressed and moves towards the right mold 21. The slide column 34 pushes the two first extrusion rods 44 into the right mold groove 38 through the two first connecting columns 43 for material removal.

[0061] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.

8. The method of using the die-jointing upsetting device for easy material discharge as described in any one of claims 1-7, characterized in that, Includes the following steps: S1. The rotation of the shaft (1) drives the turntable (11) to rotate. The second roller (32) in the connecting block (13) approaches the convex surface of the turntable (11). The convex surface of the turntable (11) presses the second roller (32) and the connecting block (13) to move away from the shaft (1). The connecting block (13) presses and pushes the second ball joint (18) through the second connecting rod (14). The second ball joint (18) drives one end of the pressure rod (17) to move away from the shaft (1). As the pressure rod (17) rotates within the second U-shaped frame (16), one end of the pressure rod (17) moves away from the rotating shaft (1), and the other end of the pressure rod (17) with the adjusting bolt (19) moves closer to the rotating shaft (1). The adjusting bolt (19) pushes the cone (20), and the cone (20) pushes the right mold (21) to fit against the left mold (22) through the ejector pin (35) to close the mold. At this time, the protrusion of the cam (3) and the first roller (6) do not contact each other. S2. The second roller (32) in the connecting block (13) is close to the notch (12) in the turntable (11). The elasticity of the second spring (15) pushes the connecting block (13) to fit the notch (12), so that one end of the pressure rod (17) moves toward the direction close to the rotating shaft (1). The pressure rod (17) drives the other end of the adjusting bolt (19) to move away from the rotating shaft (1). The adjusting bolt (19) loses its pressure on the cone (20). The elasticity of the disc spring (40) pushes the cone (20) to reset. The cone (20) drives the right mold (21) to reset through the ejector pin (35). After the right mold (21) is reset, since the position of the second extrusion rod (49) remains unchanged, the right mold (21) resets and the second extrusion rod (49) enters the left mold groove (37) in the right mold (21). The material can be removed through the second extrusion rod (49). S3. As the second roller (32) in the connecting block (13) approaches the notch (12) in the turntable (11), the protrusion of the cam (3) simultaneously presses against the first roller (6). The protrusion of the cam (3) presses against the first roller (6) upward, causing one end of the jump rod (5) to move upward. Since the jump rod (5) rotates within the first U-shaped seat (4), one end of the jump rod (5) rises, and the end of the jump rod (5) with the first ball sleeve (7) moves downward. The first ball sleeve (7) moves towards... The downward movement drives the first ball joint rod (8) to move downward, and the downward movement of the first ball joint rod (8) drives the first connecting rod (9) to move downward. The first connecting rod (9) moves downward into the right mold (21) and squeezes the sliding column (34) located in the elliptical slide groove (33). The sliding column (34) is squeezed and moves towards the right mold (21). The sliding column (34) pushes the two first extrusion rods (44) into the right mold groove (38) through the two first connecting columns (43) to remove the material.
