Problems solved by technology

The stamping method is a method of using a mold to form a head on a press. This method often requires shape correction, low material utilization, high labor intensity and low dimensional accuracy.
The spinning method is a method to rotate the sheet metal and use the rotary wheel feed motion to realize rotary plastic forming to process the required head. The existing spinning method has limited processing size and high equipment cost.

Embodiment

[0012] Embodiment: a head spinning process, comprising the following steps: (1) cutting the preliminary size of the plate to be formed into the head by a cutting machine; (2) heating the preliminary cut plate to 710~750°C, And keep it for 160~180min; (3) Press the heated plate through the drum press first, and then spin it through the spinning machine. The spinning pressure is 1480~1530KN, and the spinning speed is controlled at 38~45mm / s; (4) Cut the sheet after spinning with a cutting device, and then grind and polish it with a grinding machine and a polishing machine respectively to obtain a forming head; (5) Drill the forming head through a drilling device as required hole.

Abstract

The invention discloses a seal head spinning process. The seal head spinning process comprises the following steps that (1) a cutting machine performs cutting at a preliminary size on a plate to be molded into a seal head; (2) the initially cut plate is heated to 710-750 DEG C, and the temperature is maintained for 160-180 min; (3) the heated plate is first subjected to drum pressing by a drum pressing machine, and then subjected to spinning by a spinning machine, the spinning pressure is 1480-1530 KN, and the spinning rate is controlled at 38-45 mm / s; (4) the plate after spinning is first cutby cutting, and then ground and polished by a grinding machine and a polishing machine, and a formed seal head is obtained; and (5) the formed seal head is drilled by a drilling device as required.

Description

technical field [0001] The invention relates to a head manufacturing process, in particular to a head spinning process. Background technique [0002] With the rapid development of my country's industry, the domestic oil demand is increasing year by year, and the transportation of various oil products plays an increasingly important role in heavy industry. The market demand for various large tank trucks is increasing. In the actual production process, the oil tank is usually divided into three workpieces, the tank body and the two ends of the head, which are processed and formed separately, and then the three workpieces of the tank body and the two ends of the head are butted together and formed. However, in the prior art, the production cost of the head is high, which greatly increases the production cost of the oil tank. It all uses a stretching process to stretch the head raw material through a hydraulic machine tool, but the hydraulic machine tool has a high tensile dama...
