Description
Technical Field
The invention belongs to the technical field of storage battery manufacturing, relates to storage battery pole sealing, and in particular relates to a simulation structure and a determination method for determining a pole demoulding angle.
Background
The accumulator is a product which converts electric energy into chemical energy and chemical energy into electric energy, the interior of the accumulator contains lead polar plates, dilute sulfuric acid and the like, and the accumulator is maintenance-free and is connected with the outside through a safety valve for exhausting. When the internal pressure of the battery reaches a certain value, the safety valve opens the exhaust. The storage battery is provided with a terminal connected with the outer edge, the terminal is connected with the inside of the battery through a pole, the joint of the pole and a battery cover is usually sealed by a sealing ring, and then epoxy resin is injected to strengthen and seal. Because the inside gas pressure that has of battery, if seal between utmost point post and the middle cover is not good, can cause terminal department to climb sour corrosion later stage. The reason for the poor sealing between the pole and the middle cover is that the matching degree between the sealing ring and the pole is not very good. This is because, in order to the convenient drawing of patterns of utmost point post during cast joint, utmost point post drawing of patterns angle is too big, leads to the matching degree not high between sealing washer and the utmost point post, and in the use, the sealing washer upwarps under the effect of sloping face at the utmost point post to influence the sealed effect of sealing washer and utmost point post.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a simulation structure for determining the pole demoulding angle, and the simulation structure is used for screening the most suitable pole demoulding angle by simulating the use environment, so that the pole demoulding is convenient, and the problem of poor sealing caused by upturned sealing rings can be prevented.
The invention is realized by the following technical scheme:
the simulation structure for determining the pole demoulding angle comprises a simulation middle cover, a simulation pole assembly and a sealing ring; the simulation pole assembly comprises a base and a simulation pole arranged on the base, a through hole for the simulation pole to pass through is formed in the simulation middle cover, a limit boss matched with the sealing ring is arranged on the inner wall of the through hole, and the sealing ring is sleeved on the periphery of the simulation pole.
With above-mentioned emulation structure, simulate actual sealing washer and the cooperation condition of utmost point post, the sealing ring snare is located emulation utmost point post periphery, matches the back with spacing boss, pours epoxy glue into the through-hole, places and solidifies in the resin curing kiln, and the distance of upwarping is gone up to the measuring sealing ring after solidifying to judge the degree of cooperation of the utmost point post and the sealing washer of the drawing of patterns angle that uses.
Further, one end of the simulation middle cover, which is far away from the base, is provided with a circle of shaft shoulder which extends outwards, and the simulation middle cover is conveniently separated from the simulation pole assembly through the shaft shoulder which is arranged in a handheld manner.
Further, a transverse air hole is formed in the joint of the bottom end of the simulation pole and the base, a longitudinal air hole is formed in the center of the simulation pole, and the longitudinal air hole is communicated with the transverse air hole. Through the setting of bleeder vent for the simulation structure is in the experimental process, and the evacuation of gaseous in the airtight cavity that the simulation middle cover formed with the simulation utmost point post subassembly has got rid of the interference of internal pressure, has ensured experimental data's accuracy.
Further, when the longitudinal ventilation holes are communicated with the transverse ventilation holes, inverted T-shaped ventilation holes are formed.
Furthermore, the demolding angle of the simulated polar column is 2-6 degrees, and generally, the minimum demolding angle of the polar column cannot be smaller than 2 degrees, and demolding is facilitated more conveniently when the demolding angle is larger, but the probability of upward warping of the sealing ring is larger when the demolding angle is larger, so that the polar column with the most suitable demolding angle is verified and screened by arranging a plurality of polar columns with the demolding angles of 2-6 degrees.
Furthermore, the diameter of the inner wall of the through hole, which is close to one end of the base, is 8-12 mm, and the through hole is suitable for verifying the pole sealing condition of a battery with the common battery capacity of 12-52 A.h in the market.
The beneficial effects of the invention are as follows:
the simulation structure simulates the actual battery pole sealing, and carries out a curing test to determine the optimal demolding angle of the pole, thereby facilitating pole demolding and preventing the sealing quality problem caused by upwarp of the sealing ring.
For different products, the simulation polar posts and the sealing rings of the corresponding products can be used to obtain a preferred scheme through simulation, thereby providing a basis for developing new products and saving verification time and real object cost investment.
