Description

Technical Field

[0001] The invention relates to the technical field of copper rod production, in particular to extrusion equipment based on multi-stage fixation for copper rod extrusion molding. Background Art

[0002] Hydraulic press is one of the commonly used equipment for copper rod extrusion molding. It uses Pascal's law to transmit pressure through liquid media (usually oil). When working, the motor drives the oil pump to deliver hydraulic oil to the working cylinder. When the pressure oil enters the piston cavity of the working cylinder, the piston generates huge pressure under the action of the oil pressure, pushing the mold (extrusion cylinder and extrusion rod and other components) to extrude the copper rod blank. This pressure can reach a very high value, which can cause the copper rod blank to undergo plastic deformation under the constraint of the mold, thereby obtaining the desired shape.

[0003] When traditional copper rods are extruded, the extrusion equipment needs to use a clamp to ensure that the center of the copper ingot and the center of the mold are in the same straight line. If the two are not concentric, the copper material will exert a large friction and lateral force on one side of the mold when it flows in the mold. When the copper material is extruded to one side of the mold, the pressure and friction on the mold wall on this side are higher than other parts, which can easily cause local wear of the mold to increase. Once the mold is worn, the surface quality of the copper rod will be the first to be affected, and scratches, pits and other defects will appear. When it is severely worn, the shape of the mold changes, and the dimensional accuracy of the copper rod is also affected, and the production cost increases accordingly. After all, frequent mold changes will inevitably lead to increased production costs and extended production time. Therefore, when extruding copper ingots of specific specifications, it must be equipped with a clamp that matches it. Replacing the clamp will take a certain amount of time, which is time-consuming and labor-intensive, and reduces production efficiency.

[0004] Therefore, those skilled in the art provide an extrusion device for copper rod extrusion molding based on multi-stage fixation to solve the problems raised in the above background technology. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an extrusion device for copper rod extrusion molding based on multi-stage fixation. The device has the advantages of placing the copper ingot inside the placement groove and then driving the sealing plate to slide inside the sealing groove through the pressure of the output end of the hydraulic cylinder on the abutment rod, thereby pressurizing the inside of the sealing cavity, so that the tooth plate drives the tooth ring to rotate, and at the same time the cam rotates and abuts against the surface of the limit block, and drives the metal roller to slide toward the center of the placement groove through the limit block. The movable structure of the metal roller can also perform multi-stage fixed clamping from multiple angles on the outside of the copper ingot according to copper ingots of different specifications, effectively reducing the problems of copper rod size deviation and irregular shape caused by the position offset of the copper ingot, thereby improving the molding accuracy of the copper rod, etc., and solving the problem that the traditional copper rod extrusion molding requires a clamp to ensure that the copper ingot is coaxial with the center of the mold. If they are not concentric, the flow of copper material will cause excessive local force and aggravated wear of the mold, thereby affecting the surface quality and dimensional accuracy of the copper rod, increasing the cost, and replacing the adapter clamp is time-consuming and labor-intensive, and will also reduce the production efficiency.

[0006] To achieve the above, after the copper ingot is placed in the placement groove, the pressure of the output end of the hydraulic cylinder on the abutment rod can drive the sealing plate to slide in the sealing groove, so that the inside of the sealing cavity can be pressurized, so that the tooth plate drives the tooth ring to rotate, and at the same time the cam rotates and abuts against the surface of the limit block, and drives the metal roller to slide toward the center of the placement groove through the limit block.

[0035] One end of the connecting tube 401 away from the fixing rod 51 is fixedly connected to the inside of the bottom plate 1011, and the inside of the sealing groove 53 is connected with the inside of the sealing cavity 1012 through the connecting tube 401. By setting the connecting tube 401, the internal air pressure of the sealing groove 53 and the sealing cavity 1012 can be made the same.

[0036] The surface of the tooth plate 1016 is meshedly connected to the surface of the gear ring 104 , and the surface of the tooth plate 1016 is slidably connected to the inside of the fixing seat 4 . The sliding of the tooth plate 1016 can drive the gear ring 104 to rotate.

The tooth ring 104 drives the cam 97 to rotate through the rotating shaft 103, the universal shaft 98 and the driving shaft 96, and drives the limit block 94 to slide away from the cam 97 through the friction between the cam 97 and the surface of the limit block 94. The limit block 94 drives the metal roller 91 to slide toward the center of the placement groove 7 through the positioning bearing 93 and the fixed shaft 92, and abuts against the surface of the copper ingot;

[0041] Finally, the copper ingot clamped by the metal roller 91 is pushed into the mold 3 for extrusion through the hydraulic cylinder 2. When the copper ingot is clamped by multiple stages and pushed into the mold 3, due to its precise positioning, the copper ingot can be ensured to be in the ideal center position during the process of entering the mold 3, effectively reducing the problems of copper rod size deviation and irregular shape caused by the position offset of the copper ingot, thereby improving the forming accuracy of the copper rod.
