[0002] Cold heading is a process in which pressure is applied to a metal blank using a cold heading die, causing it to deform at room temperature. The core principle of the processing method that obtains parts of the required shape and size by deformation is to apply pressure to the metal blank using a mold, and to promote the redistribution and transfer of the metal volume through multiple upsetting, extrusion and other processes, so as to finally form the required part.

During the workpiece clamping and transfer process, the clamping force is not adjustable, which can lead to unstable clamping. As a result, the workpiece cannot be accurately placed in the center position of the next cavity, affecting the symmetry and dimensional accuracy of subsequent upsetting, and in severe cases, causing scrap.

Each cold heading cavity has a push rod located inside the lower die base 2 at its bottom. The push rod can eject the workpiece inside the cold heading cavity. The upper die base 3 is mounted on the inner top wall of the base 1. The upper die base 3 is provided with multiple cold heading punches. The multiple cold heading punches can cooperate with the multiple cold heading cavities to achieve cold heading of the workpiece. The column 4 is vertically installed on the inner bottom wall of the machine base 1. A first electric push rod 41 is horizontally installed on the outer wall of the column 4 near the lower die base 2. A second electric push rod 42 is vertically installed on the output end of the first electric push rod 41 through a support plate. The first electric push rod 41 can be driven to extend to the top of the lower die base 2. A gripper cylinder 6 that can clamp the workpiece is installed on the output end of the second electric push rod 42. The moving mechanism 5 is set at the bottom of the column 4. The moving mechanism 5 can drive the column 4 to move horizontally along the arrangement direction of multiple cold heading die cavities.
[0030] After the cold heading punch performs cold heading on the workpiece, the ejector pin pushes the workpiece to the top surface of the lower die base 2. The second electric push rod 42 drives the first electric push rod 41 to move to the top of the lower die base 2. The second electric push rod 42 then drives the gripper cylinder 6 to move down to remove the workpiece from the lower die base 2 and clamp it. Then, the moving mechanism 5 drives the column 4 to move, transferring the workpiece from one cold heading processing area to the next cold heading processing area, so as to realize continuous cold heading processing of the workpiece.
[0031] like Figure 1 and Figure 2 As shown, the moving mechanism 5 includes an electromagnetic slide rail 51 and a slider 52. The electromagnetic slide rail 51 is installed on the inner bottom wall of the machine base 1. The electromagnetic slide rail 51 is arranged horizontally along the arrangement direction of multiple cold heading mold cavities. The slider 52 is horizontally slidably disposed on the top surface of the electromagnetic slide rail 51. The column 4 is vertically fixed to the top surface of the slider 52.
[0032] With the cooperation of the electromagnetic slide rail 51 and the slider 52, the column 4 can move along the cold heading mold cavity arrangement direction to realize the transfer of workpieces.
[0033] like Figure 1 and Figure 2 As shown, the electromagnetic slide rail 51 is fixed to the scale grating 53 on the outer wall of the side away from the lower mold base 2. The scale grating 53 is arranged along the sliding direction of the slider 52. A grating reading head 55 located outside the scale grating 53 is installed on the outer wall of the slider 52 through the connecting plate 54. The grating reading head 55 is set horizontally towards the scale grating 53. A second controller 56 is set on the outer wall of the column 4. The input end of the second controller 56 is electrically connected to the grating reading head 55, and the output end of the second controller 56 is electrically connected to the electromagnetic slide rail 51 to control the operation of the electromagnetic slide rail 51.
[0034] During the sliding process of slider 52, grating reading head 55 measures the displacement of slider 52 by detecting scale grating 53. The second controller 56 controls electromagnetic slide rail 51 according to the data detected by grating reading head 55, so that slider 52 stops at a specified position, so as to ensure that the workpiece can be accurately placed into different cold heading mold cavities.
[0035] like Figure 2 and Figure 3As shown, the gripper cylinder 6 is equipped with a pressure regulating component 61 that can automatically adjust its gripping force. The pressure regulating component 61 includes a vision sensor 611, a proportional pressure valve 612, and a first controller 613. The vision sensor 611 is installed on the gripper cylinder 6 to identify the workpiece. The proportional pressure valve 612 is installed in the air circuit of the gripper cylinder 6 to regulate the pressure of the supplied compressed air. The first controller 613 is installed on the outer wall of the column 4. The input end of the first controller 613 is electrically connected to the vision sensor 611, and the output end of the first controller 613 is electrically connected to the proportional pressure valve 612 to control the operation of the proportional pressure valve 612.
[0036] When transferring the workpiece, the vision sensor 611 can identify the shape, size and posture of the workpiece. The first controller 613 controls the proportional pressure valve 612 according to the detection data to adjust the pressure of the compressed air supplied in the air circuit of the gripper cylinder 6, so as to realize the automatic adjustment and control of the clamping force of the gripper cylinder 6 for different workpieces or different processing stages, so as to achieve stable clamping of the workpiece.
[0037] like Figure 2 and Figure 3 As shown, a rotary cylinder 43 is installed at the output end of the second electric actuator 42. A concave seat 44 is fixedly connected to the output end of the rotary cylinder 43. A motor 45 is horizontally installed on the outer wall of the concave seat 44. A rotary shaft 46 extending into the concave seat 44 is coaxially fixed to the output end of the motor 45. The rotary shaft 46 and the concave seat 44 are rotatably engaged. The gripper cylinder 6 is fixedly connected to the outer wall of the rotary shaft 46.
[0038] The rotating cylinder 43 and the motor 45 work together to easily flip the clamped workpiece, so as to adjust the workpiece posture and place the workpiece in different cold heading cavities for processing. like Figure 1 , Figure 2 and Figure 4 As shown, cleaning brushes 57 are fixedly attached to both outer walls of the connecting plate 54 along the sliding direction of the slider 52. The cleaning brushes 57 are provided with bristles that contact the scale grating 53 on the outer wall near the scale grating 53. The bottom ends of both cleaning brushes 57 are in contact with the inner bottom wall of the machine base 1. The cleaning brushes 57 slide in cooperation with the top surface of the inner bottom wall of the machine base 1.
[0039] During the movement of slider 52, cleaning brush 57 can clean scale grating 53, remove dust and small impurities attached to the surface of scale grating 53, and reduce the possibility that dust and impurities will affect the detection accuracy of grating reading head 55.
[0040] like Figure 1 , Figure 4 and Figure 5As shown, both cleaning brushes 57 are equipped with blow pipes 58, and both blow pipes 58 have multiple air nozzles 581 located inside the bristles on their outer walls. The air nozzles 581 are arranged at an angle toward the side away from the connecting plate 54. The base 1 is equipped with an air blowing mechanism 7 that can supply air into the two blow pipes 58.
[0041] When cleaning the scale grating 53 with the cleaning brush 57, the air supply mechanism box blows air into the blow pipe 58 and sprays it out through the air nozzle 581 to clean the brush bristles, reducing the possibility of dust and impurities adhering to the brush bristles and ensuring the cleaning effect of the cleaning brush 57.
[0042] like Figure 1 , Figure 5 and Figure 6 As shown, the blowing mechanism 7 includes a concave shell 71, a slide plate 72, an air bladder 73, and a pressing component 74. The concave shell 71 is fixed to the outer wall of one side of the base 1, with the open end of the concave shell 71 facing upwards. The bottom surface of the slide plate 72 is slidably connected to the inner wall of the concave shell 71 by a spring 721. The top surface of the slide plate 72 is arc-shaped. The air bladder 73 is installed inside the concave shell 71. The air bladder 73 is located at the bottom of the slide plate 72 and contacts the bottom surface of the slide plate 72. An air supply pipe 731 is connected to the air bladder 73. The end of the air supply pipe 731 away from the air bladder 73 is connected to both blowing pipes 58. The pressing component 74 is set on the inner bottom wall of the base 1 to repeatedly press the slide plate 72 downwards. The extrusion component 74 includes a lead screw 741 and a cam 742. The lead screw 741 is horizontally rotatably connected to the inner bottom wall of the machine base 1. The lead screw 741 is arranged along the sliding direction of the two cleaning brushes 57 and horizontally passes through the two cleaning brushes 57. The cleaning brushes 57 are threadedly driven to engage with the lead screw 741. The cam 742 is fixed to the outer wall of the end of the lead screw 741 that extends to the top of the concave shell 71. The cam 742 engages with the arc surface at the top of the slide plate 72.
[0043] During its movement, the cleaning brush 57 drives the lead screw 741 to rotate, causing the cam 742 to reciprocate to squeeze the slide plate 72. This causes the air bag 73 to reciprocate to supply air into the blow pipe 58, and the air is then blown out through the air nozzle 581 to clean the brush bristles, thus achieving self-cleaning of the cleaning brush 57 and ensuring its cleaning effect.
[0044] Working principle: With the cooperation of the first electric push rod 41 and the second electric push rod 42, the gripper cylinder 6 is moved to the top of the lower mold base 2. After the gripper cylinder 6 clamps the workpiece, the column 4 is moved by the slider 52 set on the electromagnetic slide rail 51, so as to realize the transfer of the workpiece along the arrangement direction of multiple cold heading cavities, and to facilitate the transfer of the workpiece from one cold heading processing area to the next cold heading processing area, so as to realize the continuous cold heading processing of the workpiece. When the gripper cylinder 6 is clamping and transferring the workpiece, the vision sensor 611 can identify the shape, size and posture of the workpiece and transmit the detection data to the first controller 613. The first controller 613 adjusts the pressure of the compressed air supplied in the air circuit by controlling the proportional pressure valve 612, so as to realize the automatic adjustment and control of the clamping force of the gripper cylinder 6 for different workpieces or different processing stages. When the slider 52 slides along the electromagnetic slide rail 51 to transfer the workpiece, the grating reading head 55 measures the displacement of the slider 52 through the detection scale grating 53, and then the second controller 56 controls the electromagnetic slide rail 51 to stop the slider 52 at the specified position, so as to ensure that the workpiece can be accurately placed into different cold heading mold cavities. During the movement of slider 52, the cleaning brush 57 on the connecting plate 54 can clean the surface of the scale grating 53, removing dust and tiny impurities attached to the surface of the scale grating 53, reducing the possibility that dust and impurities will affect the detection accuracy of the grating reading head 55. During the movement of cleaning brush 57, the lead screw 741 will rotate, causing the cam 742 to reciprocate to squeeze the slide plate 72, causing the air bag 73 to reciprocate to supply air into the blow pipe 58, and the air is sprayed out through the air nozzle 581 to blow and clean the brush bristles, realizing the self-cleaning of cleaning brush 57 and ensuring the cleaning effect of cleaning brush 57.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
