Abstract

The present invention relates to the technical field of bolt processing equipment, and discloses a high-strength bolt cold heading equipment and cold heading process, including a feeding unit, a cold heading unit and a transposition material discharging and cleaning unit. After the raw material of the present invention falls into the temporary storage bucket, the driving gear drives the driven gear to rotate, and the rotation of the driven gear drives the entire longitudinal shift roller to start rotating, and the temporary storage bucket is driven to move downward as a whole through the cylindrical cam groove, which can reduce the impact force when discharging the material, and the L-shaped sealing plate on the temporary storage bucket re-seals the feed port, so that the material will not continue to slide, which has a protective effect. During the rotation of the driving gear, the lateral shift roller of the side wall rotates synchronously, and then drives the temporary storage bucket to move horizontally at this time through multiple groups of stepped grooves, and the horizontal movement distance is different, and then moves to different positions of the cleaning box, preventing the discharged raw materials from stacking in the same position and affecting the later cleaning operation.

[0023] Step 4: Horizontal shift. When the raw material slides into the temporary storage bucket, the driving gear is rotated, wherein the driving gear drives the driven gear to rotate, and the rotation of the driven gear drives the entire longitudinal shift roller to start rotating, and the temporary storage bucket is driven to move downward as a whole through the cylindrical cam groove, and the L-shaped sealing plate on the temporary storage bucket re-seals the feed port, so that the material will not continue to slide;

During the rotation of the driving gear, the lateral shift rollers on the side wall rotate synchronously, and then the temporary storage bucket is driven to move horizontally through multiple sets of step grooves, and the horizontal movement distances are different, so it moves to different positions of the cleaning box to prevent the discharged raw materials from stacking in the same position. The positioning affects the subsequent cleaning operation. After the temporary storage bucket unloads the material to the specified position, the insertion rod contacts the positioning plate at the bottom, and the positioning plate squeezes the insertion rod, and the insertion rod squeezes the rocker arm. The rocker arm starts to rotate at this time, and the rocker arm drives the lifting plate to rotate, and the parts on the lifting plate are dumped outward, thereby achieving the purpose of unloading. In addition, due to the gear ratio of the driving gear and the driven gear, it is ensured that when the longitudinal shift roller rotates one circle, the temporary storage bucket can slide along a step groove and move to the specified position. Therefore, when the longitudinal shift roller rotates continuously, the temporary storage bucket can slide along the three step grooves and move to different positions in turn, and unloading operations are performed without stacking, making cleaning cleaner.

After the temporary storage bucket 306 unloads the material to the specified position, the insertion rod 309 contacts the positioning plate 3096 at the bottom, and the insertion rod 309 is squeezed by the positioning plate 3096. The insertion rod 309 squeezes the rocker arm 3081. The rocker arm 3081 starts to rotate at this time, and the rocker arm 3081 drives the lifting plate 308 to rotate, and the parts on the lifting plate 308 are dumped outward, thereby achieving the purpose of unloading.

[0065] The implementation principle of a high-strength bolt cold heading device and cold heading process of this embodiment is as follows:

[0066] First, the surface of the metal wire rod 400 is pretreated; the metal wire rod is installed in the feeding unit 100, and the raw material is continuously fed to the cold heading unit 200 through the feeding unit 100; the cold heading unit 200 performs cold heading forming operation on the input raw material, and the raw material after cold heading slides onto the cleaning box 301 inside the transposition unloading cleaning unit 300;

[0067] When the raw material slides along the guide plate 3015 to the feed port 3016, it falls into the temporary storage bucket 306 through the feed port 3016, and then the drive motor 302 is started. The drive motor 302 drives the transmission shaft 3021 to rotate, and the transmission shaft 3021 can drive the driving gear 303 and the transverse shift roller 310 to rotate, wherein the driving gear 303 drives the driven gear 3031 to rotate, and the rotation of the driven gear 3031 drives the positioning shaft 3041 to rotate inside the mounting groove 3043, and the longitudinal shift roller 304 installed on the surface starts to rotate, and the position of the cylindrical cam groove 3042 on the surface changes synchronously, and the guide slider 305 and the guide rod 3051 slidingly connected to the cylindrical cam groove 3042 slide on the limit rod 3052, and then when the position of the cylindrical cam groove 3042 changes, the shift slider 3061 and the temporary storage bucket 306 can be pushed to move downward as a whole, which can reduce the impact force when the internal raw material is discharged.

[0068] And the top plate 3062 on the temporary storage bucket 306 can slide downward with the temporary storage bucket 306, and at this time, the L-shaped sealing plate 3074 is squeezed by the reset spring 3073, pushing the baffle 3072 and the reset rod 3071 to slide inside the reset cover 307, so that the L-shaped sealing plate 3074 can reseal the feed port 3016, so that when the raw materials inside the temporary storage bucket 306 fall, the feed port 3016 is in a closed state, ensuring that the material is in a stationary state and will not slide at will, thereby achieving a protective effect.

[0069] When the lateral shift roller 310 rotates synchronously, the positioning slider 311 is driven to slide on the positioning rod 3111 through multiple sets of step grooves 3101, and the stepped telescopic rod 3113 on the positioning slider 311 can pull the temporary storage bucket 306 to move horizontally. Since the lengths of the step grooves 3101 are different, the horizontal movement distances are different, and the temporary storage bucket 306 moves to different positions of the cleaning box 301, preventing the discharged raw materials from stacking in the same position and affecting the subsequent cleaning operations. Due to the gear ratio of the driving gear 303 and the driven gear 3031, it is ensured that when the longitudinal shift roller 304 rotates one circle, the temporary storage bucket 306 can slide downward, and the transverse shift roller 310 rotates one-third of a circle, so that the temporary storage bucket can slide along a step groove 3101 and move to a specified position. Therefore, when the longitudinal shift roller 304 continues to rotate, the temporary storage bucket 306 can slide along the three step grooves 3101 in turn, move to different positions in turn, and perform material unloading operations. The rotation of the longitudinal shift roller 304 and the transverse shift roller 310 can mix and stir the internal cleaning liquid, so as to better perform impurity removal operations.

[0070] When the temporary storage bucket 306 moves down to the specified position, the insertion rod 309 contacts the positioning plate 3096 at the bottom, and the insertion rod 309 is squeezed by the positioning plate 3096. The insertion rod 309 is opened and slides upward along the limit seat 3091. At this time, the partition plate 3094 squeezes the squeezing spring 3095, and the squeezing spring 3095 is convenient for later resetting. When the insertion rod 309 moves up, the connecting rod 3092 on the insertion rod 309 drives the sliding rod 3093 to slide on the strip groove 3082 of the rocker arm 3081, and then the rocker arm 3081 starts to rotate at this time, and the rocker arm 3081 drives the lifting plate 308 to rotate, and the parts on the lifting plate 308 are dumped outward, thereby achieving the purpose of unloading.
