Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, a low temperature ball drop test apparatus 10 can be implemented with multiple drop heights. In a low-temperature environment, the steel ball 80 falls down to a certain height and is hit on the product 90 to be detected, and the steel ball is used for detecting the low-temperature strength of the product 90 to be detected.
The stainless steel ball 80 mm in diameter weighs 500 g.
The low temperature ball drop test apparatus 10 capable of achieving multiple drop heights includes a first substrate 20, a second substrate 30, three third substrates 60, and a ball drop tube 40.
The first substrate 20 is provided with a groove 21. The groove 21 has a depth of 10mm and a diameter of 50 mm.
The second substrate 30 is detachably disposed above the first substrate 20, a pressing space 31 is provided between the second substrate 30 and the first substrate 20, and the pressing space 31 is used for pressing the product 90 to be tested, so that the product 90 to be tested is well fixed. The product to be measured 90 is in the form of a flat plate, which is a small piece cut out of an actual product.
The second substrate 30 is provided with a ball falling hole 32 for allowing the steel ball 80 to fall on the product 90 to be measured. The position of the ball drop hole 32 corresponds to the position of the groove 21. The product 90 to be tested is essentially pressed between the ball drop hole 32 and the recess 21.
The ball dropping pipe 40 is arranged above the groove 21, and the inner diameter of the ball dropping pipe 40 is 53 mm. Preferably, the ball dropping tube 40 is integrally formed with the second substrate 30, so that the structure is more stable and no additional fixing device is required to fix the ball dropping tube 40.
The ball dropping pipe 40 is vertically arranged, and the steel ball 80 naturally drops along the ball dropping pipe 40 at the top of the ball dropping pipe 40. After falling down, the steel ball 80 is hammered on the product 90 to be detected, and the groove 21 provides a space for the deformation of the product 90 to be detected. The inner surface of the drop tube 40 is smooth so as not to affect the dropping speed of the steel ball 80.
The upper edge 21a of the groove 21 is also subjected to arc treatment with an arc radius of 1mm to properly protect the product 90 to be measured and the steel ball 80.
In order to drop the ball dropping tube 40 at a specific height, a third base plate 60 is provided, and the third base plate 60 is fixed to the second base plate 30 by a support rod 33 and a nut 34.
Referring to fig. 2 and 3, a valve plate 50 is slidably disposed on the third base plate 60.
The ball dropping tube 40 has an insertion groove 41 formed in a wall thereof, and the valve plate 50 is inserted into the ball dropping tube 40 through the insertion groove 41. Valve plate 50 is used to support steel ball 80 to make steel ball 80 stay at a specific height, and valve plate 50 is also used to release supporting steel ball 80 to make steel ball 80 naturally fall down.
The front end of the valve plate 50 can be pushed to the middle position of the ball dropping tube 40 to support the lowest end of the steel ball 80, and the valve plate 50 can be completely pulled out of the inner space of the ball dropping tube 40 to release the support, i.e. the valve plate 50 can be inserted in the insertion groove 41 in a push-pull manner. The valve plate 50 (or the third base plate 60) is calculated to be set at a height such that the steel ball 80 naturally falls from a specific height.
As shown in fig. 3 and 1, the rear end of the valve plate 50 is bent upward to form a limiting protrusion 51, the front end of the limiting protrusion 51 is provided with a front limiting member 61, and the rear end of the limiting protrusion 51 is provided with a rear limiting member 62. The main body of the valve plate 50 is disposed below the front stopper 61. The restricting protrusion 51 is restricted by the front restricting member 61 when the valve plate 50 is pushed forward to the maximum, and the restricting protrusion 51 is restricted by the rear restricting member 62 when the valve plate 50 is pulled backward to the maximum. The front stopper 61 and the rear stopper 62 are both in the form of a long plate and are fixed to the third base plate 60.
Since the maximum position of the forward end of the valve plate 50 needs to be ensured so that the valve plate 50 can support the lowest point of the steel ball 80, only the front stopper 61 may be provided without the rear stopper 62.
Of course, the front and rear retainers 61, 62 may be eliminated, such as empirically or by providing markings on the valve plate 50 to control where the front end of the valve plate 50 rests when the valve plate 50 is maximally inserted into the drop tube 40.
In order to realize that the steel balls 80 fall from three different heights and improve the applicability of the low-temperature falling ball testing device 10, three insertion grooves 41 with different heights (namely, distributed up and down) are formed in the falling ball pipe 40. The position of the insertion groove 41 depends on the height at which the steel ball 80 falls. Of course, two, four, five or more insertion grooves 41 may be provided according to the required number of falling heights of the steel balls 80.
In order to drop the steel ball 80 from different heights, at least two insertion grooves 41 are provided, and when two insertion grooves 41 are provided, the steel ball 80 can drop from two different heights.
Three third base plates 60 are provided to match the insertion grooves 41, and a valve plate 50 is provided on each third base plate 60.
In this embodiment, each insertion groove 41 is provided with a valve plate 50, which is a preferable scheme and has the advantage of simple operation. In other technical solutions, when at least two insertion grooves 41 are formed in the ball dropping tube 40, the number of the valve plates 50 is one, and the valve plates 50 are removed and inserted into the corresponding insertion grooves 41 according to the height at which the steel balls 80 need to drop.
The third base plate 60 is provided mainly for facilitating mounting of the valve plate 50 and the front and rear stoppers 61 and 62. In other embodiments, the third base plate 60 may not be provided, for example, the valve plate 50 may be fixed only by the insertion groove 41.
As shown in fig. 2 and 3, a pulling rope 52 is further connected to the rear end of the valve plate 50, and the pulling rope 52 is a steel wire rope. Whole low temperature ball test equipment 10 that falls sets up in the low-temperature box to directly test the low temperature intensity of the product that awaits measuring in low temperature environment, need not make low temperature ball test equipment 10 keep the back for a certain time in the low-temperature box and take out equipment from the low-temperature box and carry out the ball test like some prior art, improved measurement accuracy. The pulling rope 52 extends out of the low-temperature box, the valve plate 50 can be pulled out of the ball dropping pipe 40 by pulling the pulling rope 52 out of the low-temperature box, the low-temperature box does not need to be opened to operate or the low-temperature ball dropping test equipment 10 does not need to be taken out of the low-temperature box, therefore, the temperature environment during testing cannot be influenced, and the test result is more accurate. The valve plate 50 is reset manually.
As shown in fig. 3, a positioning mechanism 70 is further disposed between the first substrate 20 and the second substrate 30.
The positioning mechanism 70 includes positioning bosses 71 provided at both ends of the first substrate 20 and positioning hole grooves 72 provided at both ends of the second substrate 30. When the second base plate 30 is disposed above the first base plate 20, the positioning protrusions 71 are inserted into the positioning hole grooves 72 for positioning in order to position the ball drop tube 40 and the ball drop hole 32 (see fig. 1) directly above the groove 21.
Of course, it is also possible to provide the positioning projections 71 on the second substrate 30 and the positioning hole grooves 72 on the first substrate 20.
The positioning mechanism 70 may also be provided in other forms, such as bending the edge of the first substrate 20 upward, where the bent portion catches on the periphery of the edge of the second substrate 30.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
