Description

Technical Field

[0001] The invention belongs to the field of mechanical technology, and in particular relates to a testing device for measuring the demoulding force of a crystalline material. Background Art

[0002] In the field of mechanical manufacturing and materials science, the demoulding force of crystalline materials is an important physical parameter, which directly affects the efficiency of the production process and the quality of the product. Traditional demoulding force testing methods usually rely on manual operation or simple mechanical devices, which have problems such as low precision, complex operation, and poor repeatability. Therefore, the development of an automated, high-precision demoulding force testing device has important practical significance.

[0003] Most of the existing demoulding force testing equipment has a complex structure and is difficult to adapt to crystalline materials of different sizes and shapes. In addition, the existing equipment often cannot guarantee the force transmission accuracy during the measurement process, resulting in inaccurate measurement results. Therefore, there is an urgent need for a demoulding force testing equipment with a simple structure, easy operation and high measurement accuracy. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to provide a test bench for detecting the crystallization demoulding force, which can automatically and accurately measure the demoulding force of crystalline materials, and has a simple structure and is easy to operate.

[0005] Technical solution: In order to solve the above problems, a test bench for detecting crystallization demolding force described in the present invention includes an aluminum profile frame, a servo motor, a hydraulic cylinder power unit, a screw slide and a demolding actuator. The servo motor is connected to the screw slide through a coupling, and the screw slide is vertically fixed on the aluminum profile frame. The demolding actuator includes a hydraulic cylinder, a lower end cover connecting plate, an integrated guide structure, a force sensor, a guide rod, a replaceable calibration sleeve and a replaceable demolding rod. The hydraulic cylinder is fixed to the slide of the screw slide through the hydraulic cylinder connecting plate, and the lower end cover connecting plate is connected to the hydraulic cylinder through a locking screw. The integrated guide structure is connected to the lower end surface of the lower end cover connecting plate. A force sensor is provided inside the integrated guide structure, and the upper side of the force sensor is connected to the extension rod of the hydraulic cylinder, and the lower side is connected to the guide rod. The guide rod passes through the replaceable calibration sleeve and is connected to the replaceable demolding rod.

[0006] Furthermore, nylon casters are respectively installed at the four lower corners of the aluminum profile frame, the screw slide and the hydraulic cylinder power unit are fixed to the upper end and the front end of the aluminum profile frame using T-shaped screws, the servo motor is connected to the screw slide through a coupling, and the central axis of the servo motor coincides with the central axis of the screw slide.

[0007] Furthermore, the base of the hydraulic cylinder is evenly provided with four circular holes VI; the connecting plate of the hydraulic cylinder is evenly provided with four circular holes I and eight circular holes II, and the circular holes VI on the base of the hydraulic cylinder are respectively connected to the slide surface of the screw slide by screws.

[0008] Furthermore, four circular holes III, four circular holes IV and one circular hole V are evenly arranged on the lower end cover connecting plate. The four circular holes IV pass through the lower end of the hydraulic cylinder and are connected to the lower end cover connecting plate through the four locking nuts. The extension rod of the hydraulic cylinder can pass through the circular hole V.

[0009] Furthermore, the integrated guiding structure is evenly provided with four circular holes Ⅶ, two guide pillars and four circular holes Ⅸ, and the four circular holes Ⅶ of the integrated guiding structure and the circular hole III of the lower end cover connecting plate are connected by screws; the force guiding rod is respectively provided with two arc guide grooves and eight circular holes Ⅹ, and the arc guide grooves cooperate with the guide pillars of the integrated guiding structure, so that the force guiding rod can only move along the axial direction of the guide pillars of the integrated guiding structure, which not only prevents the hydraulic rod of the hydraulic cylinder from rotating, but also has a certain guiding effect on the movement trajectory of the force guiding rod.

[0010] Furthermore, the central axes of the hydraulic rod of the hydraulic cylinder, the force sensor, the force guide rod, and the replaceable demoulding rod coincide when installed.

[0011] Furthermore, the replaceable demoulding rod is made of magnetic material and passes through the replaceable calibration sleeve to be attracted to the force-guiding rod, thereby simplifying the replacement steps of the demoulding rod.

[0012] Furthermore, during the test, the working steps of the crystallizer demoulding force test bench are as follows:

[0013] S1. Turn on the power of the test bench and start the servo motor and hydraulic cylinder power unit. The servo motor drives the screw slide through the coupling, driving the demoulding actuator to move up and down, thereby moving the replaceable calibration sleeve and the replaceable demoulding rod to the specified test environment.

[0014] S2. When the replaceable demoulding rod reaches the preset depth, keep the equipment still and wait for the crystallized material to fully crystallize around the demoulding rod to form a stable crystal layer.

[0015] S3. After crystallization is completed, the hydraulic cylinder power unit transmits high-pressure oil to the hydraulic cylinder through a high-pressure hose, driving the extension rod of the hydraulic cylinder to move downward. The extension rod of the hydraulic cylinder transmits the pressure to the force sensor, the force sensor transmits the force to the force guide rod, and the force guide rod transmits the force to the replaceable demoulding rod. Under the action of the force, the replaceable demoulding rod and the replaceable calibration sleeve produce relative displacement, so that the crystallized materials on their surfaces are separated, thereby completing the demoulding process.

[0016] S4. Record the demoulding force data measured by the force sensor for subsequent analysis. After the test is completed, the servo motor drives the screw slide to reset the demoulding actuator to the initial position, the hydraulic cylinder power unit stops supplying oil, and the extension rod of the hydraulic cylinder is retracted. According to the requirements of the next test, replace the replaceable calibration sleeve and the replaceable demoulding rod to prepare for the next test.

[0017] The present invention provides a test bench for detecting crystallization demoulding force, which has the following beneficial effects:

[0018] 1. The present invention effectively prevents the hydraulic rod of the hydraulic cylinder from rotating due to external force during the demolding process by connecting the guide column of the integrated guide structure with the guide groove of the force guide rod, thereby avoiding demolding deviation. The coaxial design in which the central axes of the extension rod of the hydraulic cylinder, the force sensor, the force guide rod and the replaceable demolding rod completely overlap ensures that the force transmission path is a straight line, avoiding the dispersion or deviation of the force, thereby ensuring the vertical transmission of the demolding force. At the same time, the replaceable calibration sleeve is fixedly connected to the integrated guide structure by screws, which is not only used to calibrate the position of the demolding rod, but also plays a guiding role to ensure that the demolding rod always maintains a vertical direction during movement. This fixing and guiding design further enhances the vertical transmission accuracy of the demolding force and significantly improves the demolding stability and measurement accuracy.

[0019] 2. The equipment realizes automatic operation through servo motor and hydraulic cylinder power unit, which reduces manual intervention and improves test efficiency. Automatic operation also reduces human errors and ensures the consistency of test results.

[0020] 3. The replaceable demoulding rod of the equipment is made of magnetic material, which can pass through the replaceable calibration sleeve and attract the guide rod. This design not only simplifies the replacement steps of the demoulding rod, but also realizes the installation without disassembly, significantly improves the operating efficiency, reduces the time cost of equipment maintenance and replacement of parts, and further enhances the ease of use and flexibility of the equipment.

[0021] 4. The test equipment for detecting the crystallization demoulding force uses aluminum profiles as the main frame, which is light and strong. At the same time, the overall design is compact, saving space in the laboratory or production workshop. In addition, nylon casters are installed under the aluminum profile frame, which makes the equipment easy to move and facilitates flexible deployment between different working areas, further improving the practicality and ease of operation of the equipment. This design not only enhances the portability of the equipment, but also ensures the stability and safety of the equipment during movement. BRIEF DESCRIPTION OF THE DRAWINGS
