Month dotting tool for aluminum alloy low-pressure hub casting die

Abstract

The invention relates to the field of auxiliary equipment for hub production and manufacturing, in particular to a month dotting tool for an aluminum alloy low-pressure hub casting die. The month dotting tool comprises a profile-following fastener and a cutter, wherein the profile-following fastener is of a concave structure; the shape of an inner cavity of the profile-following fastener is the same as the shape of the upper part of a wheel core sleeve at the top of a low-pressure casting upper die; twelve month dotting holes are formed in the top position of the profile-following fastener andform a circle; the cutter comprises a cutter handle, a cutter body and a cutter tip, wherein the cutter handle, the cutter body and the cutter tip are sequentially connected; the length of the cutterbody is the same as the depth of each month dotting hole; and the diameter of the cutter body is the same as the aperture of each month dotting hole and is smaller than the diameter of the cutter handle. According to the month dotting tool, month dots with consistent specifications can be punched on the hub die, so that the qualified rate of hub products is improved.

Description

technical field [0001] The invention relates to the field of wheel hub manufacturing auxiliary equipment, in particular to a monthly marking tool for aluminum alloy low pressure wheel hub casting molds. Background technique [0002] The standardization of engraving or marking the year and month of production on the back cavity of the wheel hub has risen to the level of law in many developed countries, so that foreign product customers pay special attention to this aspect. At present, domestic related industries are still using iron hammers and fine cutters to operate, specifically: on the wheel hub mold, the hammer is used to hit the knife to make points, so that the wheel hub mold is correspondingly recessed. One dot represents January production, two dots represent February production, and so on. Depressed points are naturally formed on the wheel hub product processed by the wheel hub mold after dotting, which represents its production month. [0003] However, in product...

AI Technical Summary

Problems solved by technology

[0003] However, in production and application, the monthly dots processed by manual dotting by workers are prone to deviation, or different shades, and the arrangement style is not beautiful and not standard

The month marks on the processed wheel products often fail to meet the customer's audit standards and need to be reworked, consuming a lot of manpower and material resources

Although the month points processed by the machining center on the wheel hub mold have high precision, the processing cycle is too long to keep up with the production progress of the workshop
