Description

Technical Field

[0001] The utility model belongs to the technical field of nut processing equipment, in particular to a high-efficiency hot upsetting forming auxiliary device for nuts. Background Art

[0002] In the production process of some high-strength nuts, hot upsetting process is used to achieve manufacturing. The so-called hot upsetting process refers to first using a high-frequency furnace or other related heating equipment to heat the workpiece to be processed to a specific temperature. Then, the heated workpiece is placed on the hot upsetting machine, and then stamped with the help of a mold to form it into the shape of a nut. For example, in the field of automobile manufacturing, high-strength nuts used in some key parts are often produced through this hot upsetting process to ensure that they have excellent performance and reliable quality.

[0003] A highly efficient hot forging auxiliary device for nuts with a publication number of CN 216502134 U is retrieved. The device blocks most of the cooling water by forming an inverted V-shaped water retaining structure through two water retaining plates before punching, thereby preventing excessive cooling water from contacting the nuts to be hot forged, thereby ensuring that the nuts are at the optimal hot forging punching temperature, improving the quality of the nuts, reducing the defective rate, and making the hot forging of the nuts more efficient. When the punch descends, the water retaining mechanism is driven away from the punch by the push-down assembly, so that the punch can pass through the gap between the two water retaining plates, which is convenient for punching. The cooling water can always cool the punch, ensuring the service life of the punch.

[0004] The above-mentioned comparative example has the following shortcomings: although most of the cooling water can be blocked by a carefully designed water retaining structure, the position of the forming mother mold is below the water retaining structure. After the forming work is completed, the staff must use manual pliers to remove the formed nuts. This operation method is not simple and easy. It places high demands on the staff. The staff not only need to have certain operating experience, but also must master the corresponding operating skills. In addition, the cooling water sprayed during the cooling process will remain on the pier or flow directly to the ground. The residual cooling water will make the surface of the pier slippery, increasing the possibility of staff slipping and getting injured. If the cooling water flowing to the ground is not cleaned up in time, it may cause the ground in the working area to be slippery, affecting the walking of personnel and the normal operation of equipment.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model adopts the design of the quick clamping structure. When the nut completes the stamping process, the staff can accurately move it to the external position of the nut by pulling the pull ring. Then, the cylinder is started to work, driving the two clamping plates to clamp the nut tightly. Thereafter, the pull ring is continued to be pulled to drive the linkage block and the linkage plate located in the middle of the two linkage blocks to achieve synchronous movement.

At the same time, the coolant will flow to the rectangular groove 12 through the lower water tank 11, and then be guided by the rectangular groove 12 to the collection frame 41 for centralized collection. Finally, the coolant can flow out in an orderly manner through the drain pipe 42, realizing the effective collection and discharge of the coolant, and avoiding the disordered accumulation and flow of the coolant in the working area.

The semi-finished nut is punched and formed through the cooperation of the punch head 53 and the molding mother mold 13. At this time, the staff can accurately move it to the external position of the nut by pulling the pull ring 37.
