Problems solved by technology

The method of welding and forming square tubes has the following defects and deficiencies: 1. Long processing time period, low efficiency, and high cost; 2. There are too many welding parts, and the joints of each part are welded by full welding, which deforms after welding. Large, the size error is too large, and the surface of the overall frame is uneven, and it is not flat when it is docked with the 100-level laminar flow, and the size is also very different. There are gaps that need to be filled with glue to achieve sealing; 3. Since the corners of the square tube are welded, After welding, the polishing is not vertical, the R angle is inconsistent, the wire drawing line is not straight, and the appearance is not beautiful

Embodiment 1

[0043] Figure 1 to Figure 6 The first embodiment of the forming method of the laminar flow hood supporting frame of the present invention is shown, comprising the following steps:

[0044] S1: blanking: blanking a slab whose total length is equal to the perimeter of the required support frame;

[0045] S2: Setting V-shaped notches and welding grooves: cutting V-shaped notches along one side of the slab at each bisector of the slab, and cutting welding grooves at both ends of the slab;

[0046] S3: Square tube forming: set four bending lines A, B, C and D along the slab, and bend the slab into a square tube along the four bending lines, and carry out section welding along the butt edge of the square tube;

[0047] S4: Frame forming: bend the square tube along the three V-shaped notches so that the welding grooves at both ends of the square tube are butted, and perform spot welding and polishing along the three bending lines and the welding grooves.

[0048] With this method,...

Embodiment 2

[0054] Figure 7 to Figure 14 The second embodiment of the forming method of the laminar flow hood supporting frame of the present invention is shown, comprising the following steps:

[0055] S1: blanking: blanking two slabs with different lengths and the sum of the lengths is equal to the circumference of the required support frame, wherein the length of the long slab is three times that of the short slab;

[0056] S2: Set up V-shaped notches and welding grooves: cut V-shaped notches along one side of the slab at each bisector of the long slab, and cut at both ends of the long and short slabs welding groove;

[0057] S3: Square tube forming: set four bending lines A, B, C and D along the long slab and short slab, and bend the long slab and short slab into two square tubes along the four bending lines. Segment welding is carried out on the butt edge of two square pipes;

[0058] S4: Frame forming: bend the rectangular tube into a U-shaped tube along the two V-shaped notches, ...

Abstract

The invention discloses a laminar flow hood supporting frame forming method and a supporting frame. The laminar flow hood supporting frame forming method includes the following steps of blanking; V-type notch and welding groove forming; square tube forming; frame forming, wherein a square tube is bent along three V-type notches so that the welding grooves in the two ends of the square tube can bein butt joint, and spot welding and polishing are carried out along three bending lines and the welding grooves. The supporting frame is manufactured through the laminar flow hood supporting frame forming method. The laminar flow hood supporting frame forming method has the advantages of being short in machining cycle, high in efficiency, low in cost and capable of improving the seal performance and appearance aesthetic degree.

Description

technical field [0001] The invention mainly relates to the forming technology of the laminar flow support frame, in particular to a forming method and the support frame of the laminar flow cover support frame. Background technique [0002] In the pharmaceutical industry, laminar flow hoods are widely used, and the setting of laminar flow hoods often requires support frames to support them. In the prior art, the laminar flow support frame is assembled and welded by multiple parts, and the parts are assembled and welded by square tubes. Each square tube is processed by multiple processes. First, the square tube is sawed and cut. Then wire cut the welding bevel, and after the overall welding, it is necessary to process the square hole and the overall wire drawing and polishing. There are the following defects and deficiencies in the method of welding and forming square tubes: 1. Long processing time period, low efficiency, and high cost; 2. There are too many welding parts, an...
