Description

Technical Field

[0001] This application relates to the technical field of cold heading production, and particularly to a cold heading production device. Background Art

[0002] The cold heading process is one of the new processes of metal pressure processing with little or no cutting. It is a processing method that utilizes the plastic deformation of metal under the action of external force and, with the aid of a die, redistributes and transfers the metal volume to form the required parts or blanks. The cold heading process has the advantages of improving material utilization rate and productivity, and is suitable for the production of workpieces with high surface quality and high dimensional accuracy requirements. It is most suitable for the production of standard fasteners such as bolts, screws, nuts, rivets, and pins.

[0003] Today's cold heading machines have reached the advanced level of specialization and high efficiency. For example, a high-efficiency cold heading device for screw production with the publication number CN117181987A includes a frame plate with a cavity structure inside; a cold heading impact component arranged inside the frame plate, with a punching plate at the bottom of the cold heading impact component, and a plurality of upper dies detachably arranged at the bottom of the punching plate, and corresponding lower dies arranged at the bottom of the frame plate; a material pushing component arranged at the bottom of the frame plate and on the side of the lower die; a feeding component arranged outside the frame plate; among them, the material pushing component includes a first cylinder arranged outside the frame plate; a pushing plate connected to the output end of the first cylinder; a second cylinder arranged at one end of the surface of the pushing plate; and a plurality of claws that clamp or release the screw blank under internal drive; the screw blank is fed onto the claws through the feeding component for clamping, and the first cylinder cooperates with the second cylinder to drive the claws clamping the screw blank to move horizontally and vertically, and cooperate with the cold heading impact component to perform cold heading stamping on the screw blank one by one between multiple lower dies and upper dies.

[0004] However, the above-mentioned prior art still has some defects in cold heading production: 1. In the above-mentioned prior art, the screw blank is fed onto the claws through the feeding component for clamping, and then the blank is cold headed. However, in the actual production process, the blank used for processing screws is usually uncut wire rod, which needs to be preliminarily sheared before cold heading processing, and there is still room for improvement.

[0005] 2. In the above-mentioned prior art, the first cylinder cooperates with the second cylinder to drive the claws clamping the blank to move horizontally and vertically, and cooperate with the cold heading impact component to perform cold heading stamping on the screw blank one by one between multiple lower dies and upper dies. However, the upper and lower dies in the above-mentioned prior art are not convenient to replace, and the processed screws are not collected, and there is still room for improvement.

Detailed implementation manners

[0031] The following is a further detailed description of the present application in conjunction with the attached Figures 1 to 9 drawings.

[0032] An embodiment of the present application discloses a cold heading production device, which can apply pressure to a wire at room temperature to cause plastic deformation and deform it into a specific shape in a processing process. Embodiment 1:

[0033] Reference Figure 1 , a cold heading production device, including a frame 11 and a loading rack 12 arranged at the side end of the frame 11. The frame 11 and the loading rack 12 are connected by a connecting frame 13. Symmetrically sliding doors 14 are arranged on the frame 11. The sliding doors 14 are used to close the frame 11 to prevent danger caused by the wire popping out when applying pressure during cold heading.

[0034] During cold heading, the coil bar on the loading rack 12 is fed into the frame 11, and then the wire is cold headed by the device inside the frame 11 to make it plastically deformed into a specific shape.

[0035] Reference Figure 2 , which is a schematic structural diagram of the cold heading device 2 of the present invention. In order to plastically deform the wire fed into the frame 11 into a specific shape, a cold heading device 2 is arranged inside the loading rack 12. The cold heading device 2 includes a mounting plate 21 arranged inside the frame 11. An installation table 22 is arranged at the upper end of the mounting plate 21. Installation holes 23 are evenly opened in the installation table 22. Cold heading bottom dies 24 are installed in the installation holes 23. The cold heading bottom dies 24 are detachable and replaceable so as to process the wire into the required shape. A sliding hole 25 is jointly opened between the mounting plate 21 and the bottom of the frame 11. A cold heading sliding frame 26 is slidably arranged on the sliding hole 25, and the cold heading sliding frame 26 is located on the side of the installation table 22 facing the loading rack 12. When driving the cold heading sliding frame 26 to slide in the sliding hole 25, the wire in the cold heading bottom die 24 is cold headed. A number of cold heading mounting blocks 27 corresponding to the cold heading bottom dies 24 one by one are arranged at the upper end of the cold heading sliding frame 26. Cold heading top dies 28 are arranged at the side ends of the cold heading mounting blocks 27. The cold heading top dies 28 and the cold heading bottom dies 24 cooperate with each other to deform the wire into a specific shape.

[0036] During cold heading, first, the wire on the loading rack 12 is fed into the frame 11, and then it is sheared into a certain length by a shearing force and successively fed onto the cold heading bottom dies 24 in the adjacent installation holes 23. The cold heading sliding frame 26 is slid towards the installation table 22 to make the cold heading top dies 28 and the cold heading bottom dies 24 cooperate with each other to gradually complete the deformation of the wire on the cold heading bottom dies 24. When the wire is jointly extruded by the cold heading top dies 28 and the cold heading bottom dies 24 at the end close to the sliding door 14, the processing of the wire is completed.

[0037] Reference Figure 3, which is a schematic structural diagram of the demolding device 3 of the present invention. In order to eject and demold the wire deformed by the cold heading top die 28 in the cold heading bottom die 24 from the cold heading bottom die 24, a demolding device 3 is further provided on the mounting plate 21. The demolding device 3 includes a demolding sliding frame 31 slidably arranged on the sliding hole 25, and the demolding sliding frame 31 is located on the side of the mounting table 22 away from the feeding frame 12. When the demolding sliding frame 31 slides in the sliding hole 25, the wire in the cold heading bottom die 24 is ejected and demolded. The cold heading sliding frame 26 and the demolding sliding frame 31 are connected by a connecting plate 32, so that the cold heading sliding frame 26 and the demolding sliding frame 31 slide together. A plurality of demolding mounting blocks 33 corresponding to the mounting holes 23 one by one are arranged at the upper end of the demolding sliding frame 31, and demolding ejector posts 34 are arranged at the side ends of the demolding mounting blocks 33. The demolding ejector posts 34 penetrate through the mounting table 22 and extend into the cold heading bottom die 24 to eject the wire on the cold heading bottom die 24.

[0038] During continuous processing, after the wire is fed into the cold heading bottom die 24, the cold heading sliding frame 26 and the demolding sliding frame 31 are slid in the direction away from the feeding frame 12 to make the cold heading top die 28 and the cold heading bottom die 24 cooperate with each other to process the wire. Then, the cold heading sliding frame 26 and the demolding sliding frame 31 are slid in the direction facing the feeding frame 12, and the demolding ejector posts 34 eject the wire in the cold heading bottom die 24, and transfer it to the adjacent cold heading bottom die 24 close to the sliding door 14 side through the subsequent device.

[0039] Reference Figure 4 , which is a schematic structural diagram of the driving device 4 of the present invention. In order to drive the cold heading sliding frame 26 and the demolding sliding frame 31 to reciprocate together in the sliding hole 25, a driving device 4 is arranged at one end of the machine frame 11 away from the sliding door 14. The driving device 4 includes a driving motor 41 installed on the side wall of one end of the machine frame 11 away from the sliding door 14. The output shaft of the driving motor 41 is connected with a driving turntable 42. One end of a connecting rod 43 is hinged at the eccentric position of the driving turntable 42. A connecting arm 44 is arranged at the side end of the connecting plate 32, and the connecting arm 44 is hinged at the other end of the connecting rod 43. During processing, the driving motor 41 rotates the driving turntable 42, and then, driven by the connecting rod 43 and the connecting arm 44, the cold heading sliding frame 26 and the demolding sliding frame 31 reciprocate together in the sliding hole 25 through the connecting plate 32.

[0040] Reference Figure 5, which is a schematic diagram of the structure of the shifting device 5 of the present invention, in order to transfer the wire material ejected by the demoulding ejector column 34 to the cold heading bottom die 24 adjacent to the side of the sliding door 14 for further processing so that it is gradually deformed into a desired shape, a shifting device 5 is arranged between the mounting table 22 and the demoulding sliding frame 31, and a mounting frame 51 is arranged between the mounting table 22 and the cold heading sliding frame 26. Clamping arms 52 are symmetrically slidably arranged on the mounting frame 51, and mutually cooperating clamping blocks 53 are arranged between the clamping arms 52. When the clamping arms 52 slide toward each other, the clamping blocks 53 clamp the ejector column 34 being demoulded. The wire is ejected, and the clamping block 53 is offset and opposite to the cold heading bottom die 24. A telescopic rod 54 is arranged on the side wall of the mounting platform 22. A sliding vertical rod 55 is arranged at the output end of the telescopic rod 54. The sliding vertical rod 55 passes through the two clamping arms 52, and the clamping arms 52 slide on the sliding vertical rod 55. The telescopic rod 54 enables the clamping arms 52 to move axially along the telescopic rod 54 through the sliding vertical rod 55, so that the wire clamped by the clamping block 53 is sent to the position of the cold heading bottom die 24 adjacent to the side of the sliding door 14, and then is pushed into the cold heading top die 28 by the cold heading top die 28 for further plastic deformation processing.

[0041] After the demolding ejector pin 34 ejects the wire in the cold heading bottom die 24, the two clamping arms 52 move toward each other, so that the clamping block 53 jointly clamps the wire that is pushed out by the demolding ejector pin, and then the telescopic rod 54 drives the two clamping arms 52 to move toward the sliding door 14 through the sliding vertical rod 55, so that the wire is facing the position of the adjacent cold heading bottom die 24, and then the two clamping arms 52 move toward each other, and at the same time the cold heading top die 28 pushes the wire into the cold heading bottom die 24 for further processing, and then the telescopic rod 54 contracts, so that the two clamping arms 52 are reset, and the clamping block 53 faces the previous cold heading bottom die 24, ready to clamp the wire pushed out by the demolding ejector pin 34, and the reciprocating cycle is repeated to subject the wire to multi-step processing.

[0042] refer to Figure 6 , is a structural schematic diagram of the collecting device 6 of the present invention. In order to collect the wires after processing, a collecting device 6 is provided at the lower end of the frame 11. The collecting device 6 includes a collecting hole 61 jointly opened on the mounting plate 21 and the frame 11, and the collecting hole 61 is located on the side of the mounting plate 21 facing the sliding door 14. The collecting hole 61 is located below the cold heading bottom die 24 away from one end of the telescopic rod 54, so as to facilitate the collection of the processed wires. A connecting frame 62 is provided on the collecting hole 61, and a collecting frame 63 is provided at the lower end of the connecting frame 62. The processed wires fall into the collecting hole 61 and enter the collecting frame 63 through the connecting frame 62.

[0043] After the wire has been processed by the cold heading bottom die 24 and the cold heading top die 28 for multiple times, the demoulding ejector 34 ejects the wire in the cold heading bottom die 24 away from one end of the telescopic rod 54 , and the wire falls into the collecting hole 61 and enters the collecting frame 63 through the connecting frame 62 . Embodiment 2:

[0044] Reference Figure 7 , on the basis of the first embodiment, before cold heading, in order to accurately feed the wire from the loading rack 12 onto the clamping block 53 at one end away from the sliding door 14, cut it, and then feed it into the cold heading bottom die 24, a guiding device 7 is arranged on the mounting table 22 inside the frame 11 facing the loading rack 12. The guiding device 7 includes two rotating shafts 71 rotatably mounted on the inner wall of the frame 11, and the two rotating shafts 71 are distributed up and down. A driving motor 73 is mounted on the side wall of the frame 11 through a motor mounting seat 72, and the output shaft of the driving motor 73 is connected to one of the rotating shafts 71. The driving motor 73 drives the rotating shaft 71 to rotate. Transmission gears 74 meshing with each other are respectively mounted on the two rotating shafts 71. When the rotating shafts 71 rotate, the meshing of the transmission gears 74 causes the two rotating shafts 71 to rotate in opposite directions. Two guiding wheels 75 are also respectively mounted on the two rotating shafts 71. The rotation of the two rotating shafts 71 drives the guiding wheels 75 to rotate relative to each other. A connecting pipe 76 is penetrated through the side wall of the frame 11 facing the loading rack 12, and the connecting pipe 76 is opposite to the space between the two guiding wheels 75. The wire is fed into the space between the two guiding wheels 75 through the connecting pipe 76. A guiding pipe 77 is also arranged on the inner wall of the frame 11. One end of the guiding pipe 77 is opposite to the space between the two guiding wheels 75, and the opening of the guiding pipe 77 facing the guiding wheels 75 is larger, so that the guiding wheels 75 can feed the wire onto the clamping block 53 at one end away from the sliding door 14 through the guiding pipe 77. A cutting piece 78 is slidably arranged at the end of the guiding pipe 77 away from the guiding wheels 75. When the wire passes through the guiding pipe 77, the cutting piece 78 slides to cut off the wire passing through the guiding pipe 77. A connecting abutting plate 79 connected to the cutting piece 78 is arranged at the side end of the clamping arm 52. When the telescopic rod 54 pushes the clamping arm 52 to slide, the connecting abutting plate 79 drives the cutting piece 78 to cut the wire passing through the guiding pipe 77.

[0045] The wire is fed into the frame 11 through the connecting pipe 76. The driving motor 73 makes the two guiding wheels 75 rotate towards each other through the meshing of the two transmission gears 74, thereby driving the wire to be conveyed into the frame 11. After the wire passes through the space between the two guiding wheels 75, it enters the guiding pipe 77 and extends outwards. At this time, when the telescopic rod 54 pushes the clamping arm 52 to slide, the connecting abutting plate 79 drives the cutting piece 78 to cut the wire passing through the guiding pipe 77. After the wire is cut off, the clamping block 53 at one end away from the sliding door 14 clamps the cut wire, and then cold heading processing is carried out.

[0046] Reference Figure 8, which is a schematic structural diagram of the feeding device 8 of the present invention. In order to fix the coil rod and draw out the wire rod in the coil rod and feed it into the frame 11, a feeding device 8 is arranged on the feeding frame 12. The feeding device 8 includes a feeding arm 81 arranged at the side end of the feeding frame 12. The upper end of the feeding arm 81 is rotatably installed with a feeding roller 83 through a roller mounting seat 82. During processing, the feeding arm 81 passes through the coil rod, and the coil rod is placed on the feeding roller 83. A rotating stop lever 84 is hinged at the edge of the side end of the feeding arm 81. After the coil rod is placed on the feeding roller 83, the rotating stop lever 84 is lifted upward to prevent the coil rod from detaching from the edge of the feeding roller 83. A plurality of guide wheels 85 are rotatably installed on the side wall of the feeding frame 12. The wire rod is drawn out from the coil rod and passes between the guide wheels 85 to guide the wire rod and prevent the wire rod from knotting. A plurality of mounting bases 86 are evenly installed at the upper end of the connecting frame 13. A tensioning wheel 87 is rotatably installed at the upper end of the mounting base 86. After the wire rod passes between the guide wheels 85, it is wound around the tensioning wheel 87 and then led out to ensure that the wire rod is in a straightened state when it is fed into the frame 11.

[0047] During processing, the coil rod is placed on the feeding roller 83, and the rotating stop lever 84 is lifted upward to prevent the coil rod from detaching from the edge of the feeding roller 83 during processing. The wire rod drawn out from the coil rod is guided by the guide wheels 85 and alternately wound by the tensioning wheel 87, and is fed into the frame 11 through the connecting pipe 76 for processing.

[0048] Reference Figure 9 , which is a schematic structural diagram of the separating device 9 of the present invention. When the cold heading processing stops, if the coil rod is removed, in order to cut and separate the wire rods inside and outside the frame 11, a separating device 9 is further arranged at one end of the connecting frame 13 facing the frame 11. The separating device 9 includes a separating frame 91 arranged at the upper end of the connecting frame 13, and the separating frame 91 is located on the side of the mounting base 86 facing the frame 11. A shearing arm 92 is hinged in the separating frame 91. A shearing blade 93 is arranged at the lower end of the shearing arm 92. A shearing groove 94 cooperating with the shearing blade 93 is opened at the lower end of the separating frame 91. A connecting hole 95 penetrating through the separating frame 91 is opened in the middle of the side end of the separating frame 91, and the connecting hole 95 communicates with the connecting pipe 76.

[0049] After the wire rod is led out from the tensioning wheel 87, it enters the frame 11 through the connecting hole 95 and the connecting pipe 76. When cutting is required, the shearing arm 92 is pressed down, and the shearing blade 93 and the shearing groove 94 cooperate with each other to cut the wire rod together. At this time, the coil rod on the feeding roller 83 can be removed.

[0050] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
