Description

Technical Field

[0001] The utility model relates to the technical field of multi-station processing molds, and specifically relates to a multi-station mold for forming and processing hexagonal heads. Background Technique

[0002] Hexagonal workpieces, as conventional workpieces, need to be continuously processed in multiple stations through a multi-station stamping die during the processing. The continuous multi-station die refers to a cold stamping die that uses strip-shaped stamping raw materials and completes multiple stamping processes simultaneously at several different stations on a set of dies during a single stamping stroke of a press. Each time the die completes a stamping, the strip is moved a fixed distance until the product is completed.

[0003] The utility model discloses a multi-station stamping die (CN220760759U), which includes an upper die and a lower die. The upper die includes a first template and a second template. The second template is formed with a first stepped through hole, a second stepped through hole, and a third stepped through hole. A first stepped cylinder is sleeved in the first stepped through hole, and a plurality of punching die heads are formed on the first stepped cylinder. A second stepped cylinder is sleeved in the second stepped through hole, and a trimming die head is formed on the second stepped cylinder. A third stepped cylinder is in the third stepped through hole, and a grooving die head is formed at the lower end of the third stepped cylinder. A rectangular channel is formed on the upper bottom surface of the lower die, and a first die hole, a second die hole, and a third die hole are formed on the rectangular channel. The utility model is provided with a plurality of stamping stations, and can complete multiple shapes in one stamping. Moreover, the multiple stamping stations do not interfere with each other and have strong independence, which can effectively improve the stamping efficiency and stamping quality. However, during use, since the multi-station die needs to push the workpiece during the processing, once there is a slight change in the pushing amount, it may cause the processed workpiece to be incompletely formed, resulting in a certain deviation, turning the finished product into a waste product, bringing certain economic losses to the enterprise, and the workpiece may experience metal fatigue during the stamping process, resulting in too high a surface temperature of the workpiece, and it is necessary to make a reasonable judgment on the processed workpiece based on manual experience, which brings trouble to the user.

[0004] Therefore, we propose a multi-station mold for forming and processing hexagonal heads. Content of the Utility Model

[0005] The purpose of the utility model is to provide a multi-station mold for forming and processing hexagonal heads to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A multi-station mold for forming hexagonal heads, including a bottom mold, a machine body, and a locking bolt. In the middle of the upper end of the bottom mold, a mold table is cut. At the connection between the bottom mold and the mold table, a reinforcing rib is cut. And from left to right on the mold table, a rectangular punching hole, a reducing punching hole, and a hexagonal punching hole are successively cut. And the distances between the rectangular punching hole, the reducing punching hole, and the hexagonal punching hole are the same. The machine body is erected in the middle between the rectangular punching hole, the reducing punching hole, and the hexagonal punching hole on the mold table. On one side inside the machine body, an infrared sensor for detecting the surface temperature of the workpiece is installed. And on the other side inside the machine body, a displacement sensor for detecting the displacement of the workpiece is installed. At the bottom of the lower end of the machine body, a rubber gasket is fixed. And the bottom of the rubber gasket is adhesively connected to the bottom mold.

[0007] Preferably, several assembly grooves are opened on both sides of the bottom mold, and an embedded groove is opened in the middle of the inner wall of the assembly groove.

[0008] Preferably, a locking bolt is embedded in the inner wall of the assembly groove, and an opening groove is opened on the outer wall of the middle part of the locking bolt.

[0009] Preferably, a buffer gasket is attached to one side of the locking bolt, and a rubber collar is fixed at the connection between the buffer gasket and the opening groove.

[0010] Preferably, the rubber collar is embedded in the embedded groove, and there is an interference fit between the rubber collar and the embedded groove.

[0011] Preferably, the buffer gasket matches the waist-tightening hole of the assembly groove, and there is an interference fit between the buffer gasket and the assembly groove.

[0012] Preferably, the bottom mold is assembled to the mold bed through the assembly groove and the locking bolt, and the assembly groove and the locking bolt are in one-to-one matching with each other.

[0013] Compared with the prior art, the beneficial effect of the present utility model is: When the multi-station mold for forming hexagonal heads is used, the assembly groove adopts a combined design of a waist-tightening hole and a through hole to meet the assembly requirements of the locking bolt and the buffer gasket, ensuring that the bottom mold is firmly fixed on the mold bed and meeting the requirements of subsequent continuous multi-station stamping forming.

[0014] As an assembled part, a buffer gasket is attached to one side of the locking bolt. At the same time, to ensure the connection strength between the two, an opening groove is opened on the outer wall of the middle part of the locking bolt. Through the interference fit between the rubber collar and the embedded groove, the stable fixation of the locking bolt and the buffer gasket is satisfied. At the same time, the buffer gasket and the rubber collar are used as energy-absorbing and shock-absorbing components and are distributed along the outer wall of the locking bolt. The connection between them adopts an interference fit, which does not affect the normal fixation of the locking bolt and can also play a good shock-absorbing effect, ensuring that the bottom mold can be installed on the mold bed for a long time.

[0015] As a detection component, the machine body performs real-time detection on the processed workpiece moving upward. Through the displacement sensor, it can accurately detect the advancement amount of the workpiece, ensuring that during subsequent stamping forming, the error is small and the finished product rate is high, bringing good economic benefits to the enterprise. Its infrared sensor, as a temperature detection component, performs real-time detection on the surface temperature of the processed workpiece to ensure that the workpiece is stamped at a suitable temperature during the processing. And due to certain vibrations in the punching machine, rubber gaskets are provided at the bottom of the machine body. Through the energy absorption protection of the rubber gaskets, the requirement for the long-term stable operation of the machine body can be met. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment 3

[0026] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a multi-station mold for the forming process of hexagonal heads.

At this time, the user presses down the locking bolt 8, and the locking bolt 8 moves downward along the inner wall of the rubber sleeve ring 83. The buffer gasket 82 absorbs energy and protects one side of the locking bolt 8. At this time, the workpiece to be processed is pushed into the rectangular punching hole 3 through the strip for qualitative stamping, then moved to the reduced punching hole 4 to further stamp the bottom of the rectangular workpiece, and then moved to the hexagonal punching hole 5 to stamp the bottom of the processing workpiece into a hexagonal shape. At the same time, the displacement sensor 62 accurately detects the advancing amount of the workpiece to ensure that during subsequent stamping and forming, the error is small and the finished product rate is high. The infrared sensor 61, as a temperature detection component, detects the surface temperature of the processing workpiece in real time.
