Abstract
The utility model relates to the diel field of flanging bore, disclose a kind of flange precompressed unloading mechanism, comprise flange pin (1), flange pin fixed block (2), precompressed sleeve (3) and nitrogen spring (4), the bottom of described flange pin (1) is fixed on described flange pin fixed block (2), described precompressed sleeve (3) is enclosed within the shank (11) of described flange pin (1), described nitrogen spring (4) is positioned at described precompressed sleeve (3) below, and the top of described nitrogen spring (4) effectively contacts with the bottom surface of described precompressed sleeve (3).Compared with prior art, without the need to discharging push rod in flange precompressed unloading mechanism in the utility model, structural design is simpler, because precompressed sleeve is tubular structure, relative to thinner discharging push rod, non-deformability is stronger, cost is cheaper, and owing to using nitrogen spring to provide stripping force, can effectively alleviate precompressed colleting deformation, also effectively can avoid the distortion treating flange part.
Description
Technical field
The utility model relates to the diel field of flanging bore, particularly a kind of flange precompressed unloading mechanism.
Background technology
Be illustrated in figure 1 the structural representation of flange precompressed unloading mechanism in prior art, flange pin 1 is fixed in the fixing bloom 5 in a position, arranges the discharging push rod 7 that air cylinder drives 6 around flange pin 1.After plane orthogonal flange pin 1 pressure of flange part, discharging push rod 7 is depressed, and flange pin 1 is treated flange part and carried out flange, and after flange terminates, air cylinder 6 drives discharging push rod 7 to move upward and realizes the part discharging after flange.The structure of this flange precompressed unloading mechanism is comparatively complicated, and design difficulty is high; The specification of air cylinder 6 selects difficulty, and rule of thumb judge and there is error, stripping force is little, then product piece can not the normally material returned, and greatly, then product is easily out of shape stripping force; Discharging push rod 7 is comparatively thin longer, and need specific customization, cost is high, and is driven by air cylinder 6 and easily deform.
Utility model content
utility model object:for problems of the prior art, the utility model provides a kind of flange precompressed unloading mechanism, and without the need to using discharging push rod, structure is simple, stopped the situation of discharging push rod distortion, and discharging is more laborsaving, not easily causes treating flange part deformation.
technical scheme:the utility model provides a kind of flange precompressed unloading mechanism, comprise flange pin, flange pin fixed block, precompressed sleeve and nitrogen spring, the bottom of described flange pin is fixed on described flange pin fixed block, described precompressed jacket casing is on described flange pin sidewall, described nitrogen spring is positioned at below described precompressed sleeve, and the top of described nitrogen spring effectively contacts with the bottom surface of described precompressed sleeve.
Further, discharging step is provided with between the plunger of described flange pin and shank.
operation principle and beneficial effect:the utility model is used to treat flange part when carrying out flange, first flange part need the vertical flange pin in the position of flange be fixed on flange pin by treating, then external force presses down and treats flange part, treat that flange part moves down, because flange pin maintains static, so can flange be realized, in the process of flange, treat that precompressed sleeve can press down by flange part, precompressed sleeve recompression nitrogen spring, after flange terminates, remove external force, nitrogen spring resilience, causes precompressed sleeve moves, and then precompressed sleeve pushes away treats that flange part helps it to depart from flange pin.Without the need to discharging push rod in flange precompressed unloading mechanism in visible the utility model, structural design is simpler, precompressed sleeve directly will treat that flange part jack-up comes off under the effect of nitrogen spring, because precompressed sleeve is tubular structure, relative to thinner discharging push rod, non-deformability is stronger, cost is cheaper, and in mechanism, use nitrogen spring to provide stripping force, can effectively alleviate precompressed colleting deformation, also effectively can avoid the distortion treating flange part.
Accompanying drawing explanation
Fig. 1 is the structural representation of flange precompressed unloading mechanism in prior art;
Fig. 2 is flange precompressed unloading mechanism original state schematic diagram in the utility model;
Fig. 3 is the view of flange precompressed unloading mechanism compacted formula of precompressed sleeve when flange in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Present embodiments provide for a kind of flange precompressed unloading mechanism, as shown in Figures 2 and 3, be made up of flange pin 1, flange pin fixed block 2, nitrogen spring 4, precompressed sleeve 3, flange pin fixed block 2 position is fixed, flange pin 1 is fixed on flange pin fixed block 2, the shank 11 that precompressed sleeve 3 is enclosed within flange pin 1 can freely move up and down, the plunger 12 of flange pin 1 reaches above precompressed sleeve 3, nitrogen spring 4 is fixed on below precompressed sleeve 3, and the top of nitrogen spring 4 effectively contacts with the lower surface of precompressed sleeve 3; In addition, for the ease for the treatment of the discharging of flange part, between plunger 12 and shank 11, discharging step 13 is also provided with.
Mechanism original state is as Fig. 1, nitrogen spring 4 is in free state, the upper surface of precompressed sleeve 3 flushes substantially with discharging step 13 place plane, when being crushed in the plunger 12 of flange pin 1 due to external force until flange part, flange pin 1 can be treated flange part and carry out flange, move down into until flange part contact with the upper surface of precompressed sleeve 3 time, press down if continue and treat flange part, then namely precompressed sleeve 3 moves down compressed nitrogen spring 4, as Fig. 2, after flange terminates, treat that the external force that flange part is subject to is removed, now nitrogen spring 4 resilience is by precompressed sleeve 3 upwards jack-up, precompressed sleeve 3 upper surface will treat again flange part upwards jack-up, realize the discharging treating flange part, after discharging, mechanism can return to again the state of Fig. 1.
Above-mentioned embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the utility model Spirit Essence or modification, all should be encompassed within protection domain of the present utility model.
