Description

Technical Field

[0001] The present invention relates to the technical field of thermal battery pole piece processing, and specifically to a disposable thermal battery annular pole piece demoulding device. Background Technique

[0002] A disposable thermal battery, also known as a thermally activated battery, has wide applications in the fields of military and national defense, aviation and aerospace, industry and scientific research, medical equipment, deep-sea exploration, polar exploration, etc. due to its characteristics of high energy density, long storage life, and rapid activation and discharge.

[0003] A disposable thermal battery consists of pole pieces, an activation device, a heat insulation layer, a stainless steel metal shell, and external connection terminals. Since a single thermal battery needs to be stacked by multiple pole pieces, the consumption of pole pieces for disposable thermal batteries is extremely large.

[0004] When producing thermal battery pole pieces, the pole powder for producing thermal batteries needs to be formed into thin circular battery pole pieces under high pressure by a servo press in a mold, and then the battery pole pieces are ejected from the mold by the servo press. Currently, the method adopted on the production line is to directly push and demould the pole pieces in a suspended state by a pressing head, and its demoulding principle is as Figure 1 shown. The female mold 26 is arranged on the backing plate 45, the pressing head 27 is movably arranged in the female mold 26, and the pressing head 27, the female mold 26, and the backing plate 45 are all located between the upper template 43 of the servo press and the lower template 44 of the servo press. When the pressing head 27 moves vertically downward, the thermal battery pole piece 37 at the bottom of the pressing head 27 is discharged from the middle through hole of the female mold 26 and the backing plate 45.

[0005] Currently, during the demoulding process of the demoulding device, the bottom of the thermal battery pole piece is in an unconstrained suspended state. Since the thermal battery pole piece has hard brittleness after being formed under high pressure, the force on the thermal battery pole piece is uneven when it is ejected from the mold, which easily causes cracks or fractures, resulting in a high defective rate of the thermal battery pole pieces. A high defective rate means waste of raw materials, as well as an increase in the production cost and time cost of the enterprise. Therefore, how to improve the demoulding equipment has become an urgent problem to be solved by the enterprise. Summary of the Invention

[0029] The above electrical components are connected by wires. For the specific connection and control sequence, reference should be made to the following working principle, and the electrical connection should be completed according to the sequence of operation of each electrical component. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of electrical control will be given.

[0030] Working principle and usage process of the present invention: Before demolding the hot battery electrode plate 37, adjust the position of the locator 22, as Figure 15 shown. Specifically: Turn on the power supply of the device, install the ejector rod calibrator 42 on the main pressure rod 5, and lock the ejector rod calibrator 42 with the clamping screw 11. Push the locator 22 to the predetermined position (not tightened first), then push the process die base 48, process female die 47 and process punch 46 for calibration below the main pressure rod 5 (the process die base 48, process female die 47 and process punch 46 are exactly the same in shape, size and installation form as the die base 25, female die 26 and punch 27 in the demolding assembly of this device. The die base 25, female die 26 and punch 27 in the demolding assembly of this device need to be heat-treated, while the process die base 48, process female die 47 and process punch 46 do not need to be heat-treated. The process die base 48, process female die 47 and process punch 46 are only used for alignment and calibration). At this time, the process die base 48 is clamped in the locator 22, the process female die 47 is above the locator 22, the process punch 46 is in the mounting hole of the process female die 47 and above the process die base 48. When the electric push rod 4 is in the jog state, push the ejector rod calibrator 42 into the mandrel hole 27-1 opened on the process punch 46 to align the ejector rod calibrator 42 with the mandrel hole 27-1. After the locator 22 is in contact with the surface of the process die base 48, fix it on the mounting plate 1 with screws. Remove the ejector rod calibrator 42, process die base 48, process female die 47 and process punch 46, install the adjustable ejector rod 12 on the main pressure rod 5, and lock it after adjusting the demolding stroke of the adjustable ejector rod 12 according to the product requirements; When demolding the hot battery electrode plate 37, as Figure 3 and Figures 10-12 shown, push the demolding assembly (containing the pre-pressed annular hot battery electrode plate 37) into the positioning surface of the locator 22, press the illuminated button 13, the motor 15 starts, the motor 15 drives the left and right lead screw 17 to rotate, and the left and right lead screw 17 drives the left support clamp 20 and the right support clamp 21 to move to clamp and fix the die base 25. The electric push rod 4 pushes the main pressure rod 5 and the adjustable ejector rod 12 downward. The adjustable ejector rod 12 removes the mandrel 28 in the punch 27 and the die base 25 (for the process of removing the mandrel 28, please refer to Figure 10 and Figure 11), the electric push rod 4 will pause for 1.5 s. At this time, the reverse rotation of the motor 15 will drive the left clamping bracket 20 and the right clamping bracket 21 to move away from the die base 25 in the opposite direction to release the fixation of the die base 25. After 1.5 s, the electric push rod 4 continues to push down, as Figure 12 shown. At this time, the protruding part of the adjustable ejector rod 12 in the horizontal direction will press on the punch 27, and the adjustable ejector rod 12 will drive the punch 27 to move vertically downward. Since the positioner 22 is fixed to the mounting plate 1 by screws and the female die 26 is arranged above the positioner 22, the die base 25 will move when the punch 27 moves vertically downward. The die base 25 makes the push shaft 30 move downward, and the push shaft 30 compresses the spring 32. The positioner 22 supports the female die 26 and cannot move vertically downward. Thus, the thermal battery pole piece 37 located below the punch 27 is pushed out of the female die 26. During the entire demolding process, under the elastic force of the spring 32, the top of the push shaft 30 is always in contact with the bottom of the die base 25. Thus, the die base 25 continuously supports the thermal battery pole piece 37, that is, the punch 27 and the die base 25 are always in a state of pressing the thermal battery pole piece 37, thereby preventing the bottom of the thermal battery pole piece 37 from being suspended during the demolding process and generating cracks or fractures, so as to improve the qualified rate of the product. After the thermal battery pole piece 37 is pushed out of the female die 26, the telescopic end of the electric push rod 4 contracts to drive the adjustable ejector rod 12 to move vertically upward and withdraw from the mandrel hole 27-1. The operator manually removes the punch 27 and the female die 26, and then takes out the thermal battery pole piece 37, thus completing the entire demolding process.
