A CNC sieve plate welding machine tool

Abstract

The invention discloses a numerical control sieve plate welding machine tool. The machine tool comprises a machine tool body, a headstock, a numerical control panel and operation display touch display, a main shaft driving servo motor and speed change device, a longitudinal moving device and a linear guide rail. The main shaft driving servo motor and speed change device is arranged on the left side of the headstock, drives a main shaft and is connected with the main shaft, the main shaft is fixedly connected to a tool mould, the longitudinal moving device is in sliding connection with the linear guide rail, a bearing is arranged in the longitudinal moving device, and the two ends of a bearing are fixedly connected with a sieve supporting strip pressing device and a sieve supporting strip pressing operation hand wheel respectively. A servo driver and a high-frequency welding power box are installed on the upper side of the headstock. An electrode rolling disc is arranged on the upper portion of the tool mould, and a straightening, correcting and positioning device is arranged on the right side of the welding tool mould. An electrode rolling disc balance device is arranged on the upper side of the electrode rolling disc. The numerical control sieve plate welding machine tool is reasonable in structural design, fills in gaps of a sieve plate manufacturing device in China and reduces production cost for enterprises.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a sieve plate welding machine tool. Background technique [0002] The sieve plate (or sieve surface) is the most important part of the curved sieve. Taking the welded sieve plate of 50μm 120° pressure curved screen as an example, it is composed of about 2,000 acid and alkali resistant and high-strength stainless steel screen bars with a wedge-shaped cross section evenly arranged on the convex cross-section support bars with a spacing of about 10mm. The method of resistance welding is used to form a whole. The working surface of the sieve plate is processed by a special processing method, which is highly smooth, round and smooth. Wedge bars have sharp edges and are work hardened for high wear resistance. The gap between the wedge-shaped sieve bars is the sieve seam, which is the channel of the undersieve during work, and it is one of the specifications of the screen surface....

Problems solved by technology

For this kind of high-precision sieve plate manufacturing equipment, there is no such equipment in China at present, so it has caused the form that imported sieve plates dominate the domestic market, which will inevitably lead to the high price of imported sieve plates; The outflow of foreign exchange also increases the cost of production for enterprises
