Description

TECHNICAL FIELD

[0001] The utility model relates to stator core mould pressing field, concretely to a stator core stator split mould pressing frock. BACKGROUND

[0002] With the progress of science and technology and the increasing demand of industrial automation, the motor advances to high power, miniaturization and high performance, and puts forward strict requirements for the precision and quality of the stator core. The early hand-made stator core is extremely low in efficiency and difficult to guarantee the size consistency, and cannot meet the large-scale industrial production demand. In order to solve this problem, the stator core mould pressing technology gradually develops. It learns from the mould manufacturing and pressure processing principle, and integrates multi-disciplinary knowledge such as precision machinery and hydraulic transmission. After many innovations and optimizations, it has developed from the initial simple structure to the current high-precision mould, intelligent guidance and efficient pressing system. It not only can quickly press the silicon steel sheet into shape, ensure the key indicators such as core roundness and thickness to meet the standard accurately, but also greatly shorten the production cycle and reduce the labor cost, becoming the key force to promote the motor industry to modernization and scale.

[0003] In the field of modern motor manufacturing, the stator core stator split mould pressing frock plays an important role. The prepared split stator is carefully carried to the specified position of the lower mould of the mould pressing, the press is started, the slider drives the upper mould to descend at a uniform speed, the pressure head contacts the stator piece, and then the pressure is gradually applied. During this period, the guiding system ensures the accurate closing of the upper and lower moulds, and the pressure sensor monitors the pressure in real time to make the stator piece fit closely. After the pressing is completed, the slider of the press rises, and the ejection device of the lower mould pushes out the formed stator smoothly.

[0004] However, when producing split stators of different sizes, the pressure head of the stator core stator split mould pressing frock needs to be replaced. Most of the pressure heads of the frock are fixed by traditional fastening bolts and mounting seats, which makes the installation and removal of the pressure head of the frock complicated and time-consuming, resulting in low efficiency of the frock. Therefore, it is necessary to reform the existing technology. UTILITY MODEL CONTENTS

[0018] Further, the limiting block is removed from the inner wall of the mounting seat after being extruded, and the removal distance is equal to the depth of the limiting groove.

[0032] Please refer to Figure 1 - Figure 5 The outer wall of the sliding block 2 is symmetrically provided with a plurality of extrusion blocks 22, the cross-shaped design is conducive to fixing the pressing head 4 at multiple angles, uniformly disperses the force, avoids stress concentration, enhances the stability of the pressing head 4 after installation, effectively prevents the pressing head 4 from loosening due to factors such as vibration and pressure impact in subsequent use, and ensures the stability of the pressing die quality.

[0033] Please see Figure 1 - Figure 5 The outer wall of the lifting block 21 is provided with threads corresponding to the rotating threaded sleeve 23, and the inner wall of the rotating threaded sleeve 23 is tightly fitted to the outer wall of the mounting base 11. The threads form a reliable transmission link, enhancing the stability of the rotating threaded sleeve 23 during rotation, ensuring the movement accuracy of the lifting block 21 connected to the rotating threaded sleeve 23 and subsequent transmission components, and further improving work efficiency and operation quality.

[0034] Please see Figure 1 - Figure 6 The outer wall of the extrusion block 22 is designed at an angle, and the outer wall of the limiting block 3 is designed at an angle corresponding to the extrusion block 22. The oblique design is beneficial to the gradual and gentle increase or elimination of the extrusion force, making the process of the limiting block 3 being pushed out of the limiting groove 41 by the spring 31 more smooth, avoiding problems such as the limiting block 3 being ejected too violently and impacting surrounding components due to sudden unloading.

[0035] Please see Figure 1 - Figure 6 The outer wall of the limiting block 3 is provided with a mounting block for the limiting spring 31, and the spring 31 connects the limiting block 3 and the inner wall of the mounting base 11. The spring 31 provides a reset power for the limiting block 3, which is stable and controllable, reducing the risk of operation errors and ensuring the continuity and accuracy of the disengagement action.

[0036] Please see Figure 1 - Figure 4 The outer wall of the pressure head 4 is symmetrically provided with multiple sets of limiting grooves 41, and the limiting grooves 41 correspond to the limiting block 3. Multiple sets of limiting grooves 41 provide multiple fixing points for the pressure head 4, ensuring that the pressure head 4 is stably in the correct position, improving the positioning accuracy after installation, and ensuring the smooth operation of the die.

[0037] Please see Figure 1 - Figure 4 After being extruded, the limiting block 3 moves away from the inner wall of the mounting base 11, and the moving distance is equal to the depth of the limiting groove 41. The precise displacement ensures the fit of the limiting block 3 and the limiting groove 41, so that there will be no gap or looseness due to displacement deviation, effectively reducing the scrap rate.

[0038] The working principle of the utility model is: when the pressing head 4 in the stator core stator split mould tooling needs to be disassembled and replaced, first of all, the staff reaches the outer wall of the mounting seat 11, and gently rotates the rotating threaded sleeve 23 mounted thereon, the rotating threaded sleeve 23 is closely engaged with the lifting block 21 through fine design thread, along with the rotation of the sleeve, according to the basic principle of threaded transmission, the lifting block 21 moves along the linear track stably and synchronously, the displacement of the lifting block 21 is transmitted to the sliding block 2 connected thereto, so that the sliding block 2 drives the extrusion block 22 to slide downward synchronously, in this process, the extrusion block 22 gradually moves away from the limiting block 3, the extrusion force originally tightly against the limiting block 3 disappears slowly, after the limiting block 3 loses the extrusion of the extrusion block 22, under the pushing of the elastic potential energy of the spring 31, gradually moves to the inner wall of the mounting seat 11, away from the limiting groove 41, when the limiting block 3 completely moves out of the limiting groove 41, the limiting of the pressing head 4 is released, the staff can easily and freely take down the old pressing head 4 for replacement;

[0039] After the new pressing head 4 is replaced, the staff reversely rotates the rotating threaded sleeve 23, and the opposite threaded motion makes the lifting block 21 drive the sliding block 2 to move upward, the sliding block 2 in turn drives the extrusion block 22 to climb upward synchronously. The extrusion block 22 approaches the limiting block 3 again, gradually applies extrusion force, forces the limiting block 3 to overcome the elastic force of the spring 31, and slowly moves to the limiting groove 41, finally, the limiting block 3 is pushed by the extrusion block 22, smoothly clamped into the limiting groove 41, and the limiting work on the new pressing head 4 is accurately and firmly completed, the working steps of replacing the pressing head 4 are reduced, the working efficiency and the use efficiency of the tooling main body 1 are improved, the stability and continuity of production are ensured, and the maintenance cost and the scrap rate are reduced.
