Description

Technical Field

[0001] The utility model relates to the technical field of ductile iron part processing, in particular to a ductile iron part processing device. Background Art

[0002] Ductile iron is a high-strength cast iron material with spheroidal graphite, usually composed of iron, carbon, manganese, silicon, copper and other elements. During the casting process, by adding spheroidizers, the carbides inside the casting are converted into spheroidal structures, thereby improving the strength and toughness of the material. Compared with ordinary cast iron, ductile iron has higher strength, better toughness, wear resistance, corrosion resistance and excellent cutting performance. Ductile iron is very common in the manufacture of mechanical parts, such as gears, bed, rollers, etc. Its high strength and good plasticity and toughness enable mechanical equipment to withstand greater loads and pressures, and improve the service life and reliability of the equipment;

[0003] When processing ductile iron parts, it is necessary to use a processing device to pre-fix the parts to ensure the stability of the ductile iron parts processing and facilitate the auxiliary parts processing.

[0004] The existing devices all use an upper and lower clamping method to clamp and fix parts, but the fixing traction force is poor, which easily causes the parts to be unstable and affects the processing effect.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a processing device for ductile iron parts is proposed, in order to achieve a more practical purpose. Utility Model Content

[0009] Furthermore, the traction slide plate is interlocked with the limiting slide groove and the limiting slide rail.

[0010] Furthermore, the traction slide plate forms a detachable structure through the connecting plate and the cross frame plate.

[0011] Furthermore, the sliding angles of the fixed telescopic rod and the traction slide plate are parallel, and the fixed telescopic rod forms a telescopic transmission structure through a locking sleeve and a connecting rod.

[0012] Furthermore, the anti-slip pads are distributed in a horizontal arrangement.

[0013] The utility model provides a processing device for ductile iron parts, which has the following beneficial effects:

[0014] 1. The utility model adopts the method of upper and lower mold clamping. Under the embedded basic structure, the top movable clamping table is pulled to move obliquely downward, and approaches the fixed clamping table from the oblique upper side. While pressing down, it also provides inward traction to ensure the stability of ductile iron parts during processing;

[0015] A fixed telescopic rod with a certain inclination angle is used as a transmission part, which can support pneumatic or hydraulic methods so that it can follow the limit of the limit slide groove and the limit slide rail, thereby ensuring the accuracy of traction and accurately fixing the ductile iron parts.
