Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing dies, in particular to a special drawing die for copper tubes of flanging crystallizers. Background Art

[0002] The Flanged Crystallizer Copper Tube is a specially designed crystallizer copper tube used in the process of metallurgical equipment. Its name comes from the flange structure at its end, which can increase its contact area with other components (such as the quartz tube of the crystallizer), thereby improving heat transfer efficiency and stability.

[0003] The drawing die is a tool used to process materials such as metals and plastics into the required shape or size. The drawing die is needed in the process of flanging the copper tube of the crystallizer. However, the ordinary drawing die is not convenient for flanging one end of the crystallizer copper tube and has poor practicality. Therefore, we propose a special drawing die for flanging the copper tube of the crystallizer to solve the above problems. Utility Model Content

[0007] Preferably, the circular chamber is connected to the two die grooves through two movable grooves, and the two movable grooves are respectively located at the top and bottom of one end of the circular chamber, so that the push plates in the two movable grooves can push the two extrusion plates to move.

By starting the electric push rod, the push plate pushes the two extrusion plates to move to the left, so that one end surface of the two extrusion plates rests on the flared end surface of the copper tube, thereby facilitating the extrusion of the flared end of the copper tube.

[0009] Preferably, the tapered extrusion die surface on the stretching die body and the edge of the die groove are provided with a first fillet to facilitate better contact with the copper tube during the rotation and leftward extrusion process of the stretching die body.

[0010] Preferably, the edge of one end of the extrusion plate is provided with two second rounded corners, and the two second rounded corners on the extrusion plate are located near one end of the copper tube, so as to facilitate better contact with the copper tube during the rotation and leftward extrusion of the stretching die body and the two extrusion plates.

[0011] Preferably, the driving connection mechanism includes a driving plate and a driving rod. The driving plate is fixedly installed on one end of the stretching die body away from the conical extrusion die surface, and the driving rod is fixedly installed on one side of the driving plate.

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

[0013] The special drawing die for copper tube of the flanging crystallizer sets one end of the drawing die body into a conical extrusion die surface, expands the copper tube at 45 degrees through the conical extrusion die surface on the drawing die body, and then makes one end surface of two extrusion plates abut against the expanded end surface of the copper tube through a translation driving mechanism. With the continuous leftward extrusion and rotation of the two extrusion plates on the drawing die body, the copper tube is squeezed on one side of the extrusion fixture until the expanded end of the copper tube is squeezed into a flat shape, thereby realizing the flanging process of the copper tube. The operation is simple, fast and practical. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-5 A special drawing die for a copper tube of a flanging crystallizer comprises a drawing die body 1 and a copper tube 2, a tapered extrusion die surface 3 is arranged at one end of the drawing die body 1, one end of the tapered extrusion die surface 3 on the drawing die body 1 is overlapped on the inner wall of one end of the copper tube 2, two die grooves 4 are respectively arranged on the drawing die body 1, and extrusion plates 5 are movably installed in the two die grooves 4, a circular chamber 6 and two movable grooves 7 are arranged in the drawing die body 1, and a translation driving mechanism for the two extrusion plates 5 is arranged in the circular chamber 6 and the two movable grooves 7, and a driving connection mechanism is arranged at one end of the drawing die body 1 away from the tapered extrusion die surface 3.

[0022] Furthermore, the circular chamber 6 is connected to the two die grooves 4 through two movable grooves 7. The two movable grooves 7 are respectively located at the top and bottom of one end of the circular chamber 6, so that the push plates 9 in the two movable grooves 7 can push the two extrusion plates 5 to move.

[0023] Specifically, the translation drive mechanism includes an electric push rod 8 and a push plate 9. The same push plate 9 is movably installed in the two movable grooves 7. The push plate 9 is fixedly connected to the two extrusion plates 5. The electric push rod 8 is fixedly installed on one side wall of the circular chamber 6. The output end of the electric push rod 8 is fixedly installed on one side of the push plate 9. By starting the electric push rod 8, the push plate 9 pushes the two extrusion plates 5 to move to the left, so that one end surface of the two extrusion plates 5 is against the expanded end surface of the copper tube 2, which is convenient for extruding the expanded end of the copper tube 2.

[0024] Furthermore, the edges of the tapered extrusion die surface 3 and the die groove 4 on the stretching die body 1 are provided with a first fillet 10 to facilitate better contact with the copper tube 2 during the rotation and leftward extrusion process of the stretching die body 1 .

[0025] Furthermore, two second rounded corners 11 are provided on the edge of one end of the extrusion plate 5, and the two second rounded corners 11 on the extrusion plate 5 are located at one end close to the copper tube 2, so as to facilitate better contact with the copper tube 2 during the rotation and left extrusion of the stretching die body 1 and the two extrusion plates 5.

[0026] Furthermore, the driving connection mechanism includes a driving plate 12 and a driving rod 13. The driving plate 12 is fixedly installed on one end of the stretching die body 1 away from the conical extrusion die surface 3, and the driving rod 13 is fixedly installed on one side of the driving plate 12. One end of the driving rod 13 is externally connected to a rotating extrusion mechanism, which drives the stretching die body 1 to rotate and extrude in the direction of the copper tube 2 through the rotating extrusion mechanism.

[0027] When in use: in the manufacturing process of the copper tube of the flanging crystallizer, the copper tube 2 is clamped and fixed in the extrusion fixture so that part of one end of the copper tube 2 is located outside the extrusion fixture, and the external rotating extrusion mechanism on the driving rod 13 drives the stretching die body 1 to rotate and extrude in the direction of the copper tube 2. When the conical extrusion die surface 3 on the stretching die body 1 rotates and squeezes one end of the outside of the copper tube 2, the end of the outside of the copper tube 2 is expanded to 45 degrees. After that, the electric push rod 8 is started to make the push plate 9 push the two extrusion plates 5 to move to the left, so that one end surface of the two extrusion plates 5 is against the expanded end surface of the copper tube 2. As the two extrusion plates 5 on the stretching die body 1 are continuously extruded and rotated to the left, the copper tube 2 is squeezed on one side of the extrusion fixture until the expanded end of the copper tube 2 is squeezed into a flat shape, thereby realizing the flanging process of the copper tube 2, which is simple and fast to operate and has high practicality.
