Problems solved by technology

[0003] The existing production steps of copper bars are as follows: firstly, the raw copper is heated and melted, and then the copper liquid is poured into a mold to form a copper material. After the copper material is cooled, it is sent to a drawing machine for straightening treatment. There is no protective device for the pulling head, which will easily scratch the copper bar, affect the appearance of the copper bar, and reduce the quality of the copper bar

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] As shown in the figure, a non-marking drawing head for a drawing machine includes a drawing head and a clamping device arranged inside the drawing head. The drawing head is a cylindrical hollow structure, and the inside of the drawing head is provided with a A through hole, a second through hole, the first through hole and the second through hole are internally connected, the first through hole is a cylindrical structure, the second through hole is a conical structure, and the bottom surface of the second through hole with a larger area is in contact with the The first through holes are in contact, and the clamping device includes a first extrusion block and a second extrusion block. The cross section of the first extrusion block is a right-angled trapezoidal structure. The second tapered surface of the hole fits together, the second ext...

Abstract

The invention provides a non-marking drawing head for a drawing machine, comprising a drawing head and a clamping device arranged inside the drawing head, the drawing head is a cylindrical hollow structure, and a first The through hole and the second through hole, the present invention fixes the copper material in the through hole of the drawing head through the drawing head, first clamps and fixes it through the clamping device, and the setting of the guide plate can play the role of limiting the copper material , to prevent the position of the copper material from shifting, and then press the copper material tightly through the third cylinder. The end of the piston rod of the third cylinder is provided with a pressure block, and the outer surface of the pressure block is provided with a third rubber layer. There are friction strips on the three rubber layers to further strengthen the connection with the copper material and prevent the axial deviation of the copper material. The first rubber layer, the second rubber layer and the third rubber layer can greatly reduce the damage to the copper material.

Description

technical field [0001] The invention relates to the field of copper material processing, in particular to a traceless drawing head for a drawing machine. Background technique [0002] Copper is a high-current conductive product, which is suitable for electrical engineering such as high and low voltage electrical appliances, switch contacts, power distribution equipment, and bus ducts. It is also widely used in ultra-high-current electrolytic smelting projects such as metal smelting, electrochemical plating, and chemical caustic soda. Copper material, also known as copper bus bar, copper bus bar or copper bus bar, grounding copper material, is made of the same material and has a rectangular or chamfered rectangular cross-section. It plays the role of transmitting current and connecting electrical equipment in the circuit. [0003] The existing production steps of copper bars are as follows: firstly, the raw copper is heated and melted, and then the copper liquid is poured int...
