Description
(1) technical field
The utility model relates to a kind of plant equipment, particularly relates to a kind of cupping machine.
(2) background technology
At present, the major way of measuring reinforcing bar material feature under the tensile load effect uses tension test exactly, claims again tensile test.Tension test is one of basic skills of the test reinforcing bar mechanical property of materials, is mainly used in experimental material whether standard up to specification and the performance of research material.And now when the reinforcing bar material is carried out tension test, apply constant pulling force to sample, what usually adopt is the lever application of force, but when test period was long, when the sample creep compliance was larger, application of force lever had larger inclination, affected measuring accuracy.Therefore, need a kind of device that directly applies constant pulling force and keep constant application of force direction, guarantee that the pulling force that is applied in the experimentation on the sample is constant.
(3) summary of the invention
In order to overcome the weak point of existing machinery equipment, the utility model provides a kind of cupping machine.
The technical solution of the utility model is to realize like this.
A kind of cupping machine of this programme, comprise the body main body, described body main body is provided with base, this base middle part is provided with fixing lower, described fixing lower comprises holder, snap close and stationary pipes, described stationary pipes is one section vertical with holder and be fixedly connected with round steel pipe, and described holder is fixedly connected with base, and described snap close is enclosed within the stationary pipes outside and is flexibly connected with stationary pipes; Described body main body both sides are provided with two side bracket; Be provided with control panel on described one of them side bracket; Be provided with drawing stand between described two side bracket, be flexibly connected between this drawing stand and two side bracket; Described drawing stand center bottom is provided with the upper end stationary installation, and this upper end stationary installation is constructed identical with fixing lower and is used; Described drawing stand side is provided with digital meter counter; Described body main body top is provided with cylinder and is fixedly connected with drawing stand by connecting link; Described cylinder is controlled by control panel.
Be connected by slideway between described two side bracket and the drawing stand.
Be connected by slideway between described snap close and the stationary pipes, and the slideway top on the stationary pipes is provided with catch.
Usefulness of the present utility model is: this cupping machine uses simple, and novel structure can be accomplished effectively the reinforcing bar material of test to be imposed all constant pulling force of direction, size for a long time, has guaranteed the precision of tension test.
(4) description of drawings
Accompanying drawing is front view of the present utility model.
(5) embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is made brief description.
A kind of cupping machine such as figure, comprise body main body 1, described body main body 1 is provided with base 2, these base 2 middle parts are provided with fixing lower 5, described fixing lower 5 comprises holder 6, snap close 7 and stationary pipes 8, described stationary pipes 8 is one section vertical with holder 6 and be fixedly connected with round steel pipe, and described holder 6 is fixedly connected with base 2, and it is outside and be flexibly connected with stationary pipes 8 that described snap close 7 is enclosed within stationary pipes 8; Described body main body 1 both sides are provided with two side bracket 3; Be provided with control panel 13 on described one of them side bracket 3; Be provided with drawing stand 9 between described two side bracket 3, be flexibly connected between this drawing stand 9 and two side bracket 3; Described drawing stand 9 center bottom are provided with upper end stationary installation 10, and this upper end stationary installation 10 is constructed identical with fixing lower 5 and is used; Described drawing stand 9 sides are provided with digital meter counter 11; Described body main body 1 top is provided with cylinder 4 and is fixedly connected with drawing stand 9 by connecting link 12; Described cylinder 4 is by control panel 13 controls.
Be connected by slideway between described two side bracket 3 and the drawing stand 9.
Be connected by slideway between described snap close 7 and the stationary pipes 8, and the slideway top on the stationary pipes 8 is provided with catch.
The course of work of this example: when using the utility model to carry out the tension test of reinforcing bar material, first the reinforcing bar two ends are inserted respectively in the stationary pipes 8 of fixing lower 5 and upper end stationary installation 10, then snap close 7 is moved to stationary pipes 8 and reinforcing bar sample junction by slipping, because the top of slipping on the stationary pipes 8 is provided with catch, therefore snap close 7 can not skid off stationary pipes 8, at this moment snap close 7 is locked, make stationary pipes 8 and sample be fixed together, after sample fixed, drawing stand 9 is no longer mobile, at this moment with digital meter counter 11 zeroings, then set the value of thrust of cylinder 4 outputs by control panel 13, then open cylinder 4, cylinder 4 is upwards drawn drawing stand 9 by connecting link 12, the output pulling force is fixed.Be pulled upwardly by cylinder 4 owing to drawing stand 9 this moment, produce displacement, therefore digital meter counter begins to show displacement, so just can the instant recording amount of tension, owing to use cylinder 4 and connecting link 12 that reinforcing bar sample is stretched, the pulling force that therefore applies be constant and direction constant.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
