Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of calorimetric bomb production, and in particular to an automatic clamping device for welding a calorimetric bomb. BACKGROUND

[0002] As a commonly used consumable in laboratories, a calorimetric bomb is often used as a reaction container for thermal risk assessment of reactive chemicals and chemical processes, and is widely used for thermal hazard evaluation of raw materials, intermediate products, final products and waste, such as testing of medicines, petrochemicals, agricultural fertilizers, polymers and other energetic materials, etc. For example, the calorimetric bomb can be used as a sample pool for storing test samples in an adiabatic accelerated calorimeter, a rapid screening calorimeter, and a small-sized battery adiabatic calorimeter.

[0003] As shown in Figure 11 The calorimetric bomb 5 is sequentially composed of a Φ6.35mm circular tube 51, an upper hemisphere 52 and a lower hemisphere 53 from top to bottom, and each part needs to be firmly welded, with an attractive weld, to avoid the case that the burst point of the material in the calorimetric bomb 5 appears at the weld when the material reaches the strength limit. The upper hemisphere 52 of the calorimetric bomb 8 is provided with a blind pipe positioning hole, the opening direction of the blind pipe positioning hole is at a certain angle with the center line of the circular tube 51, and a Φ2.54mm blind pipe 54 is connected in the positioning hole, the length of the blind pipe 54 is less than the diameter of the spherical part of the calorimetric bomb.

[0004] The experimental environment using the calorimetric bomb is often harsh, and the calorimetric bomb has high material selection requirements and is difficult to process. Generally, the calorimetric bomb needs to have corrosion resistance, high temperature resistance and high pressure resistance, etc. For example, it needs to withstand a pressure of 20MPa at a high temperature of 500℃. Since the structure of the calorimetric bomb is a connecting body of a spherical body and a tubular body, and parts with different wall thicknesses and shapes are welded together, the welding quality of the thin-walled part is very high. At present, the welding of the calorimetric bomb is first fixed by spot welding, then manually clamped and fixed, and then full welding is realized by rotating, which has the problems of low efficiency, poor welding consistency, easy breaking of the weld, great safety hazards, etc. If the half-sphere butt joint deviates during spot welding, breaking of the weld will occur at the spot welding position or the position with large deviation during full welding, resulting in scrap of the part.
