DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] like Figure 1 to Figure 2 As shown, the utility model provides a nut cold heading machine with a quantitative feeding function, comprising a machine body 1, a cylinder 3 is provided on the machine body 1, a punch 4 is fixedly connected to the output end of the cylinder 3, a die 6 is slidably matched on the machine body 1, a material rack 2 is fixedly connected to the machine body 1, a plurality of metal ingots 5 are slidably matched on the material rack 2, a baffle 8 is fixedly connected to the die 6, the baffle 8 is slidably matched with the material rack 2, and a blanking port 7 is fixedly connected to the machine body 1.
[0024] When the device is in use, the oil cylinder 3 is first started, and the oil cylinder 3 drives the punch 4 to move downward. A metal ingot 5 is placed in the die 6. The punch 4 moves downward to extrude the metal ingot 5 in the cavity of the die 6. After the raw material in the cavity is formed, the oil cylinder 3 drives the punch 4 to return to its original position.
[0025] like Figure 2 As shown, during the reset process of the punch 4, the die 6 is slid to the left on the machine body 1. When the die 6 moves to the left to the blanking port 7, the profile in the cavity of the die 6 is discharged from the blanking port 7 under the action of gravity.
[0026] After the material is unloaded, the die 6 is slid to the right on the machine body 1. When the die 6 moves to the right below the rack 2, the metal ingot 5 on the rack 2 is loaded into the cavity of the die 6 under the action of gravity.
[0027] After the loading is completed, the die 6 is slid leftward on the machine body 1 until the die 6 moves leftward to the initial position.
[0028] Compared with the conventional manual loading and unloading, the present application utilizes gravity to load and unload the metal ingot 5. The entire loading and unloading process only requires controlling the die 6 to slide on the machine body 1, which greatly reduces the labor intensity of the workers and reduces the labor cost.
[0029] like Figure 1-3 As shown, a driving structure is provided on the machine body 1 to drive the die 6 to perform linear reciprocating motion on the machine body 1, and the driving structure includes two pulleys 29, and the two pulleys 29 are rotatably installed on the machine body 1, and a belt 28 is installed on the two pulleys 29, and a slide bar 30 is fixedly connected to the belt 28, and a connecting plate 27 is fixedly connected to the die 6, and the slide bar 30 is slidably engaged on the connecting plate 27.
[0030] The driving pulley 29 rotates, and the rotation of the pulley 29 drives the belt 28 to rotate. The rotation of the belt 28 drives the slide bar 30 to rotate in a circle. During the rotation of the slide bar 30, the connecting plate 27 is driven to make a linear reciprocating motion, thereby driving the die 6 to make a linear reciprocating motion on the machine body 1 through the connecting plate 27 to control the loading and unloading work of the die 6.
[0031] like Figure 4-6 As shown, a cylinder body 13 is fixedly connected to the bottom of the body 1, a rack 21 is slidably fitted in the cylinder body 13, a rotating shaft 25 is rotatably mounted on the cylinder body 13, a one-way bearing 24 is mounted on the rotating shaft 25, a driven gear 23 is mounted on the one-way bearing 24, and the rack 21 matches the driven gear 23.
[0032] When the rack 21 slides in the cylinder body 13, the rack 21 drives the driven gear 23 to rotate. The driven gear 23 rotates and drives the rotating shaft 25 to rotate through the one-way bearing 24. Since the rotating shaft 25 is fixedly connected to the pulley 29, the pulley 29 will be driven to rotate when the rotating shaft 25 rotates.
[0033] When the rack 21 moves in the cylinder body 13 in the reverse direction, due to the existence of the one-way bearing 24 , after the rack 21 drives the driven gear 23 to rotate, the driven gear 23 will only idle on the one-way bearing 24 and will not drive the rotating shaft 25 to rotate.
[0034] like Figure 4-8 As shown, a connecting rod 9 is fixedly connected to the output end of the oil cylinder 3, a plunger 10 is fixedly connected to the connecting rod 9, a first connecting pipe 12 is fixedly connected to the cylinder body 13, an air cylinder 11 is fixedly connected to the first connecting pipe 12, the plunger 10 is slidably fitted in the air cylinder 11, and a first piston 22 is fixedly connected to one end of the rack 21 close to the first connecting pipe 12.
[0035] After the oil cylinder 3 is started, it will drive the connecting rod 9 to move vertically. The vertical movement of the connecting rod 9 will drive the plunger 10 to slide in the air cylinder 11. The air cylinder 11 is connected to the cylinder body 13 through the first connecting pipe 12. When the plunger 10 slides in the air cylinder 11, the plunger 10 will drive the first piston 22 to slide in the cylinder body 13 through the pressure, thereby driving the rack 21 to slide in the cylinder body 13 through the first piston 22.
[0036] like Figure 5-8 As shown, a second connecting pipe 14 is fixedly connected to the cylinder body 13, a shell 15 is fixedly connected to the second connecting pipe 14, a sliding pipe 16 is slidably matched in the shell 15, a first opening 17 is opened on the sliding pipe 16, a second opening 18 is opened on the shell 15, a nozzle 19 is provided on the sliding pipe 16, a spring is sleeved on the sliding pipe 16, and the nozzle 19 is located below the blanking port 7.
[0037] The second piston 20 is fixedly connected to the rack 21 . When the rack 21 slides in the cylinder 13 , the second piston 20 changes the air pressure in the cylinder 13 .
[0038] like Figure 5 As shown, when the air pressure in the cylinder 13 decreases, since the cylinder 13 is provided with a one-way valve 26, the outside air is inflated into the cylinder 13 through the one-way valve 26;
[0039] When the air pressure in the cylinder 13 increases, the cylinder 13 will increase the air pressure in the shell 15 through the second connecting pipe 14. When the metal ingot 5 is discharged from the blanking port 7, the metal ingot 5 will squeeze the nozzle 19 during the falling process. After the nozzle 19 is subjected to force, it will compress the spring and make the slide tube 16 slide in the shell 15. During the sliding process of the slide tube 16, the first opening 17 and the second opening 18 will overlap. When the first opening 17 and the second opening 18 overlap, the high air pressure in the shell 15 will be ejected through the nozzle 19. The airflow ejected by the nozzle 19 is aimed at the cavity of the die 6 above the blanking port 7, so that the cavity of the die 6 is cleaned and cooled by the airflow.
[0040] The working principle and use process of this utility model:
[0041] When the device is in use, the oil cylinder 3 is first started, and the oil cylinder 3 drives the punch 4 to move downward. A metal ingot 5 is placed in the die 6. The punch 4 moves downward to extrude the metal ingot 5 in the cavity of the die 6. After the raw material in the cavity is formed, the oil cylinder 3 drives the punch 4 to return to its original position.
[0042] like Figure 2As shown, during the resetting process of the punch 4, the oil cylinder 3 will drive the connecting rod 9 to move vertically, and the vertical movement of the connecting rod 9 will drive the plunger 10 to slide in the air cylinder 11. The air cylinder 11 is connected to the cylinder body 13 through the first connecting pipe 12. When the plunger 10 slides in the air cylinder 11, the plunger 10 will drive the first piston 22 to slide in the cylinder body 13 through the pressure, thereby driving the rack 21 to slide in the cylinder body 13 through the first piston 22.
[0043] When the rack 21 slides in the cylinder body 13, the rack 21 drives the driven gear 23 to rotate. The driven gear 23 rotates and drives the rotating shaft 25 to rotate through the one-way bearing 24. Since the rotating shaft 25 is fixedly connected to the pulley 29, the pulley 29 will be driven to rotate when the rotating shaft 25 rotates.
[0044] The rotation of the pulley 29 drives the belt 28 to rotate, and the rotation of the belt 28 drives the slide bar 30 to rotate in a circular manner. During the rotation of the slide bar 30, the connecting plate 27 is driven to perform linear reciprocating motion, thereby driving the die 6 to perform linear reciprocating motion on the machine body 1 through the connecting plate 27.
[0045] The die 6 is made to slide to the left on the machine body 1. When the die 6 moves to the left to the blanking opening 7, the profile in the cavity of the die 6 is discharged from the blanking opening 7 under the action of gravity.
[0046] After the material is unloaded, the die 6 is slid to the right on the machine body 1. When the die 6 moves to the right below the rack 2, the metal ingot 5 on the rack 2 is loaded into the cavity of the die 6 under the action of gravity.
[0047] After the material loading is completed, the die 6 is slid leftward on the machine body 1 until the die 6 moves leftward to the initial position.
[0048] Compared with the conventional manual loading and unloading, the present application utilizes gravity to load and unload the metal ingot 5. The entire loading and unloading process only requires controlling the die 6 to slide on the machine body 1, which greatly reduces the labor intensity of the workers and reduces the labor cost.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
