Problems solved by technology
The force value accuracy of this press is poor, the work efficiency is low, the force value series is limited, the force value range is small, the force line on the copper column (ball) has a deflection angle from the copper column (ball) axis, and the copper column (ball) is calibrated. The column is prone to the disadvantage that the end faces are not parallel,

Embodiment Construction
[0030] The present invention is described in detail below in conjunction with accompanying drawing:
[0031] The purpose of the present invention is to seek a force calibration machine with high working efficiency and accurate applied force (size and direction), which overcomes the problems of loading time, work efficiency, degree of automation, and the accuracy of the applied force value and size and direction of the copper column press in the traditional sense. And other problems, so that the static calibration of the plastic pressure measurement of the weapon chamber pressure can achieve the purpose of high precision, high efficiency, wide range and automation.
[0032] 1. Technical principle
[0033] The technical method of copper column sample loading requires that two components A and B have planes E and F respectively, and E and F are parallel, and the sample (copper column) is installed between the components. Refer to figure 1 . When the two components move relative...

The invention discloses a double-lever type press, which comprises a frame, a loading lever system and an electric control system. The loading lever system is positioned on the top of the frame; the frame has a frame structure; a balanced lever system is arranged below the loading lever system; two sets of lever systems are horizontally arranged and are parallel; a crossbeam of a loading lever 1 in the loading lever system works according to the principle of the second type of lever, a pivot is positioned at one end of the crossbeam of the loading lever 1 and a force point is positioned in the middle of the crossbeam of the loading lever 1; the balanced lever works according to the principle of the first type of lever, a pivot is positioned in the middle of the lever and a force point is positioned at one end of the lever; the force point of the crossbeam of the loading lever 1 and the force point of the crossbeam of the loading lever 2 are coupled through a reverse frame; the distances between the pivots and the force points of the two sets of levers are equal; the pivots are positioned in the same vertical line; a loading weight of the crossbeam of the loading lever 1 can move along the crossbeam of the lever; and the crossbeam of the loading lever 2 can balance the gravity of the crossbeam of the loading lever 1 and the loading weight.
Description
technical field [0001] The invention relates to a force value loading testing machine for static pressure calibration of the plastic deformation manometry method used for chamber pressure measurement, in particular to a double-lever press machine. Background technique [0002] The pressure in the chamber is one of the important tactical technical indicators of various weapon systems. It is a necessary parameter to evaluate the use and safety performance of products including guns, cannons, automatic weapons, bullets, fuzes, and propellants. Extremely important characteristic parameters in multiple links of production and product inspection. The plastic deformation manometric method has many advantages, such as easy to use, only one plastic manometer (copper column (ball) of plastic sensitive element, manometer), simple operation, stable and reliable data, and economical. Therefore, it is widely used in various The scientific research and production of guns, cannons, bullets...
