Description

Technical Field

[0001] The invention relates to a hydraulic continuous drawing mechanism and a copper alloy disc surface peeling system using the drawing mechanism, belonging to the technical field of copper alloy wire stripping. Background Art

[0002] During the production process of rolled copper alloy coils, the surface of the copper alloy wire will slightly oxidize and turn black. The oxide layer will affect the quality of subsequent products. Therefore, the surface of the copper alloy coil needs to be peeled. The existing peeling equipment mainly includes sandblasting peeling, surface grinding peeling, and peeling by pulling dies. Although there are many peeling measures, none of them are suitable for peeling coil products. The chemical rinsing method suitable for the surface treatment of coil products not only has high production costs and low production efficiency, but also causes environmental pollution, and the subsequent drying process after cleaning may cause secondary oxidation. Therefore, there is an urgent need for a device that can peel coil products. For the peeling of coil products, not only is the surface of the coil product smooth after peeling, but also with the improvement of the automation level of mechanical equipment, it is also required to achieve continuous and efficient peeling operation efficiency. The existing drawing machines can provide power drive, but the existing drawing machines are mostly used for straightening and correction of products, so they mostly use a drawing trolley or a pliers mouth to act on the surface of the product to be straightened, only the straightening effect is needed, and no attention is paid to the wear on the surface of the product. Although the drawing machine can be powered, for the peeled round products, it cannot cause wear to the round products with a smooth surface after peeling, affecting the peeling effect of the round products. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a hydraulic continuous drawing mechanism and a copper alloy disc surface peeling system which have a simple structure, are easy to operate, are suitable for continuous peeling of disc products, can realize continuous drawing of products, and will not affect the surface quality of the products.

[0004] The technical solution of the present invention to solve the above technical problems is as follows: a hydraulic continuous drawing mechanism, comprising a drawing workbench, a front drawing mechanism and a rear drawing mechanism arranged on the drawing workbench, the front and rear drawing mechanisms both comprising a moving platform, a large oil cylinder and a small oil cylinder, the moving platform moves forward and backward on the drawing workbench under the action of the large oil cylinder, the moving platform comprises a top plate, a bottom plate, a pair of positioning plates located between the top plate and the bottom plate, a pair of slide plates and a pair of half molds, a pair of the positioning plates are installed between the top plate and the bottom plate, and an activity space with a narrow front and a wide rear is formed between the pair of the positioning plates, the slide plates are correspondingly arranged on the inner side of the positioning plates, and can move forward and backward along the inclined surface of the inner side of the positioning plates, the half molds are correspondingly installed on the inner side of the slide plates, a pair of the half molds form a mold for the coiled copper alloy wire to pass through, the small oil cylinder is connected to the pair of the slide plates through a connecting mechanism, and under the action of the small oil cylinder, the pair of the slide plates drive the pair of the half molds to slide in the activity space to realize the locking and loosening of the coiled copper alloy wire by the mold.

[0005] The beneficial effects of the present invention are as follows: when the small oil cylinder is actuated, the slide plate carrying the half mold can be driven to move forward and backward in the positioning plate. Specifically, the piston rod of the small oil cylinder is extended, and the slide plate drives the half mold to move forward. Since the activity space is narrow in front and wide in the back, as the piston rod of the small oil cylinder is extended, the inner diameter of the mold formed by a pair of half molds becomes smaller to lock the product to be drawn. The action of the large oil cylinder can realize the forward and backward movement of the moving platform, thereby realizing the drawing of the product to be drawn. Compared with the existing drawing machine, the present invention has a simple structure, and realizes the continuous drawing of the product to be drawn through the alternating working cooperation of the front and rear drawing mechanisms. The entire drawing process locks and releases the product to be drawn by the mold, and the surface of the product to be drawn is not damaged. It not only realizes the power drive of the product to be drawn, but also ensures the surface quality of the product to be drawn.

Two limiting guide holes are provided at the bottom of the crossbeam. The upper part of the connecting column extends into the limiting guide hole, and the lower part of the connecting column is connected to the pressure block.

[0008] The beneficial effect of adopting the above further scheme is that the crossbeam guide mechanism not only realizes the connection between the crossbeam and the top plate, but also guides the movement of the piston rod of the small oil cylinder, reducing the radial force on the piston rod of the small oil cylinder and extending the service life of the small oil cylinder. The upper end of the connecting column moves in the limit guide hole at the bottom of the crossbeam.

The pressure block is threadedly connected to the lower end of the connecting column. The pressure block is installed on the slide plate by bolts.
