After the binding is completed, the cross-crossed telescopic rods of the test equipment withdraw from the binding area of ​​the steel bar bundling machine, and one of the cross-crossed telescopic rods can rotate around the binding node relative to the other telescopic rod. At this time, since the cross-sectional dimensions of the cross-crossed telescopic rods at the binding node change, the specific cross-sectional dimensions are smaller than when binding, until the wire section loosens, the cross-crossed telescopic rods are recovered, and the wire section falls off. After the wire section falls off, the cross-crossed telescopic rods are all extended and restored to the original cross-crossed state. The test equipment cycles the above test process to test the use process of the steel bar bundling machine.

[0003] The cyclic test action of the existing steel bar binding machine life test equipment is completed by the actuator of the cylinder to achieve fast action switching.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0031] like Figure 1 and Figure 2 As shown, a life test device for a steel bar binding machine according to a preferred embodiment of the present invention comprises a control device, a frame 1 and an execution device installed on the frame 1, wherein the control device is used to control the execution device to complete a predetermined action.

[0032] The frame 1 includes a support assembly for placing the steel bar bundling machine and a fixing assembly 4 for positioning the steel bar bundling machine. The support assembly includes a front support 2 and a rear support 3 that cooperate with each other. The steel bar bundling machine is placed on the front support 2 and the rear support 3, and the steel bar bundling machine is pressed and positioned by the fixing assembly 4. In this embodiment, the fixing assembly 4 is preferably a rotary pressing cylinder.

[0033] like Figure 3 and Figure 4 As shown, the execution device includes a push rod assembly 5 and a wire stripping assembly, and the wire stripping assembly includes a displacement unit 6, a wire stripping sleeve 7 and a telescopic rod 8, wherein the displacement unit 6 is located above the wire stripping sleeve 7, and the wire stripping sleeve 7 is sleeved on the outside of the telescopic rod 8. In the initial state, the wire stripping assembly is located in the binding area of ​​the gun head 12 of the steel bar tying machine, and the push rod assembly 5 presses the trigger 13 of the steel bar tying machine to perform binding; when the binding is completed, the wire stripping assembly moves out of the binding area of ​​the gun head 12 of the steel bar tying machine, and the displacement unit 6 moves downward, driving the entire wire stripping assembly to leave the binding area of ​​the gun head 12 of the steel bar tying machine. In addition, above the telescopic rod 8 is the wire outlet area of ​​the wire ring 11 of the steel bar tying machine, and when the steel bar tying machine is wired, the wire ring 11 surrounds the outside of the telescopic rod 8. In this embodiment, a connecting column is provided below the displacement unit 6, and the connecting column is connected to the top of the wire stripping sleeve 7 through a connecting block. Here, the number of connecting posts is two. According to actual needs, the number of connecting posts can be increased or decreased; similarly, the size of the connecting block can be increased or decreased accordingly.

[0034] like Figure 5 and Figure 6As shown, in the initial state, the telescopic rod 8 is placed in the binding area of ​​the gun head 12 of the steel bar binding machine, and the push rod assembly 5 presses the trigger 13 of the steel bar binding machine, and the wire ring 11 in the wire outlet area of ​​the steel bar binding machine surrounds the telescopic rod 8 to form a circle. In this embodiment, the push rod assembly 5 is preferably a push rod cylinder. When the steel bar binding machine completes the binding action, the wire ring 11 is twisted into a wire section and placed on the telescopic rod 8. In addition, the displacement unit 6 drives the wire stripping sleeve 7 and the telescopic rod 8 to move in a direction away from the gun head 12 of the steel bar binding machine until they are out of the binding area of ​​the gun head 12.

[0035] like Figure 7 As shown, the stripping sleeve 7 includes a sleeve body 71 and a shaft sleeve 72. A mounting hole 9 for mounting the shaft sleeve 72 is provided on one side of the sleeve body 71. The sleeve body 71 is connected to the displacement unit 6, and the telescopic rod 8 moves axially in the shaft sleeve 72. In order to better simulate steel bars of different stacking sizes and test steel bar tying machines of different calibers, the cross-sectional size of the telescopic rod 8 can be changed, and the corresponding shaft sleeve 72 can be matched at the same time, so the shaft sleeve 72 and the telescopic rod 8 are designed to be detachably connected.

[0036] In the life test device of the steel bar bundling machine described in the present invention, a telescopic assembly 10 is provided on one side of the stripping sleeve 7, and the axial movement of the telescopic rod 8 relative to the stripping sleeve 7 is mainly completed by the telescopic assembly 10. The telescopic assembly 10 is preferably a push rod cylinder, and the telescopic assembly 10 drives the telescopic rod 8 to move axially relative to the stripping sleeve 7, and the telescopic assembly 10 is arranged on the sleeve body 71.

[0037] When the telescopic assembly 10 is retracted, the telescopic rod 8 and the wire section at the upper end thereof are driven to move. During the retraction process, the wire section of the telescopic rod 8 touches the wire stripping sleeve 7 and is limited by the wire stripping sleeve 7, so that it cannot continue to move with the telescopic rod 8 until the telescopic rod 8 completely enters the wire stripping sleeve 7 and the wire section falls off the telescopic rod 8. After the wire section is removed, the displacement unit 6 contracts, and the telescopic assembly 10 drives the telescopic rod 8 to extend and re-place it in the binding area of ​​the gun head 12 of the steel bar binding machine.

[0038] The life test equipment of the steel bar bundling machine described in the present invention uses a single-axis structure of the telescopic rod 8 to simulate the cross section of the steel bar, which is used for binding during the test of the steel bar bundling machine. The execution device of the life test equipment can place the telescopic rod 8 in the binding area of ​​the steel bar bundling machine. After the steel bar bundling machine binds the telescopic rod 8, the displacement unit 6 drives the wire removal sleeve 7 and the telescopic rod 8 to simulate the operation of the steel bar bundling machine to remove the wire section. The telescopic assembly 10 drives the telescopic rod 8 to automatically disengage the wire section on the telescopic rod 8, and then repeats the simulation of the above actions. Using a single telescopic axis to simulate the cross section of the steel bar, the equipment structure is simple, the actions performed by the equipment are simplified, the time for testing a single section of the steel bar bundling machine is shortened, and the life test time of the entire steel bar bundling machine is greatly compressed. It provides assistance for product verification work, and at the same time, the simplified equipment structure helps to reduce the energy consumption of the equipment and improve the stability of the equipment.

[0039] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
