The technical matters that the present invention solves is: the repeatedly folding s tress proving installation that provides a kind of metal spring simple in structure to press from both sides, whether the repeatedly folding s tress performance that can test easily the metal spring folder is qualified.
Technical scheme of the present invention is: a kind of repeatedly folding s tress proving installation of metal spring folder, comprise base plate, it is characterized in that, described plate upper surface is provided with a guide rail and two vertical supports, described guide rail is between described two supports, and the bottom of each support all fixes with base plate, and the top of each support is separately installed with pulley, the medial surface of one of them support is provided with air pump, and the piston rod of this air pump is parallel to described base plate; The slide block that can slidably reciprocate along guide rail is installed on the described guide rail, the upper surface of this slide block is fixed with a platform, the platform upper surface is fixed with for the anchor clamps that the metal spring folder is installed, the two ends of guide rail are fixed with limited block, the piston rod end of described air pump is connected with described platform, be respectively equipped with wire rope on described each pulley, an end of each wire rope is provided with the crotch for the connection metal spring clamp, and the other end is connected with weight spare.
Be respectively arranged with pole changer on described each limited block.
Each pole changer is connected to a gas exchanger by tracheae respectively.
Described gas exchanger is connected with baroswitch.
Described each pole changer is connected to air pump by tracheae respectively.
The invention has the beneficial effects as follows: when the present invention uses, metal spring folder to be tested is installed on the anchor clamps of platform, the crotch of wire rope hangs on the metal spring folder, weight spare applies a repeatedly folding s tress to the metal spring folder, the while booster air pump, air pump promotes platform and moves back and forth back and forth under pole changer control, whether test out metal spring folder in this process is subject under the continuous repeatedly folding s tress effect deforming or rupturing in setting time, thereby whether the repeatedly folding s tress performance that can test out the metal spring folder is qualified, the present invention is simple in structure, and is easy to operate.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Referring to Fig. 1, Fig. 2, a kind of repeatedly folding s tress proving installation of metal spring folder, comprise base plate 1, base plate 1 upper surface is provided with a guide rail 2 and vertical support 31, support 32, guide rail 2 is between support 31 and support 32, and the bottom of support 31 and support 32 all fixes with base plate 1, and the top of support 31 is equipped with pulley 41, and the medial surface of support 31 is provided with air pump 5, and the piston rod of this air pump 5 is parallel to base plate 1; The top of support 32 is equipped with pulley 42.The slide block 6 that can slidably reciprocate along guide rail 2 is installed on the guide rail 2, the upper surface of this slide block 6 is fixed with a platform 7, platform 7 upper surfaces are fixed with for the anchor clamps 8 that the metal spring folder is installed, one end of guide rail 2 is fixed with limited block 91, the other end of guide rail is fixed with limited block 92, and the piston rod end of air pump 5 is connected with platform 7.Pulley 41 is provided with wire rope 10a, pulley 42 is provided with wire rope 10b, the end of wire rope 10a and wire rope 10b is provided with the crotch for the connection metal spring clamp, and the other end of wire rope 10a is connected with weight spare 11a, and the other end of wire rope 10b is connected with weight spare 11b.Be provided with pole changer 12a on the limited block 91, be provided with pole changer 12b on the limited block 92, pole changer 12a and pole changer 12b are connected to a gas exchanger 13 by tracheae respectively.Gas exchanger 13 is connected with baroswitch 14.And pole changer 12a and pole changer 12b are connected to air pump 5 by tracheae respectively.When the piston rod of air pump 5 shrinks left when mobile, slide block 6 is moved to the left and touches pole changer 12a, because pole changer 12a is connected to gas exchanger 13, and gas exchanger 13 is connected to baroswitch 14, this moment, the piston rod of air pump 5 stretched out movement to the right, slide block 6 moves right and touches pole changer 12b, the piston rod of air pump 5 shrinks again mobile left, slide block 6 is moved to the left and again touches pole changer 12a, so pole changer 12a among the present invention, pole changer 12b, the piston rod that gas exchanger 1 and baroswitch 14 can be controlled air pump 5 automatically is stretching motion repeatedly, so that slide block about 6 moves around to realize weight spare the metal spring folder is applied a repeatedly folding s tress.When the present invention uses, metal spring folder 15 to be tested is installed on the anchor clamps 8 of platform, the crotch of wire rope hangs on the metal spring folder, weight spare applies a repeatedly folding s tress to the metal spring folder, the while booster air pump, air pump promotes platform and moves back and forth back and forth under two pole changer controls, whether test out metal spring folder in this process is subject under the continuous repeatedly folding s tress effect deforming or breaking in setting time, thereby whether the repeatedly folding s tress performance that can test out the metal spring folder is qualified, the present invention is simple in structure, and is easy to operate.
