Description

Technical Field

[0001] The utility model relates to the technical field of storage batteries, in particular to a steel stamping tool for lead-acid storage batteries. Background Art

[0002] Before the battery leaves the factory, many OEMs require a date stamp to be affixed to the negative or positive terminal of the battery. This is mainly used to quickly determine the battery's factory date. The date stamp on the terminal is not easily damaged during use, so it has a wide range of applications.

[0003] Initially, the stamping method was manual direct tapping, which often affected the stamping effect due to different methods or strengths of different people. If the stamp is light, the date will be unclear and unrecognizable. If the stamp is dark, it will damage the terminal and cause acid to creep into the terminal, affecting its use. Therefore, it is necessary to design an automatic stamping device to solve the defects of manual stamping.

[0004] The existing disclosed automatic steel stamping device includes a machine body, a weight and a printing code; a hollow air compression area is provided at the upper part of the machine body, and the air compression area is connected to a three-way solenoid valve through an air inlet, and the three ports of the three-way solenoid valve are connected to an air compressor, an air inlet and an exhaust respectively; a columnar hollow weight area is provided below the air compression area, and a limit ring is provided between the weight area and the air compression area; the weight is arranged at the top of the weight area, including a hammer head and a hammer arm, and the cross-sectional size of the hammer head is adapted to the cross-sectional size of the weight area; a hammer arm is provided at the bottom of the hammer head, and the cross-sectional size of the hammer arm is smaller than the size of the hammer head, and a weight spring is provided at the outer ring between the hammer head and the bottom of the weight area; a printing code upper mold is provided at the bottom of the machine body, and the printing code is arranged at the bottom center of the printing code upper mold. The automatic steel stamping device directly sets the printing code on the upper mold, but because the printing code needs to be changed to different dates every day during use, it is necessary to design more upper molds with different date printing codes, resulting in an increase in development costs, and then an increase in production costs. Summary of the invention

[0005] The utility model aims to solve the deficiencies of the above-mentioned prior art, thereby providing a steel stamping tool for lead-acid batteries, which ensures clarity and consistency of the steel stamp on the battery terminals, and the date ejector of the tool is easy to disassemble, which can save production time.

[0006] The technical solution of the utility model is: a steel stamping tool for lead-acid batteries, comprising a chassis, a fixing sleeve, a pressing block and four date ejector rods;

[0007] The pressing block is fixed at the middle part of the lower end of the chassis;

[0008] Each of the date push rods is composed of a square head and a columnar tail connected to one end of the square head;

[0009] The end of the cylindrical tail is protruded with date numbers;

[0010] The fixing sleeve is mounted on the lower end of the chassis; a groove for giving way to the pressure block is concave in the middle of the upper end of the fixing sleeve, a square groove is provided at the bottom of the groove to match the heads of the four date push rods, and a mounting hole is provided at the bottom of the square groove to match the tails of the four date push rods; a conical hole is concave in the middle of the lower end of the fixing sleeve to match the battery terminal, and the conical hole is connected to the mounting hole.

[0011] The four corners of the square groove are all provided with avoidance grooves which penetrate the square groove.

[0012] The outer circumference of the fixing sleeve is provided with a plurality of clearance holes with different intervals, and the chassis is provided with screw holes corresponding to the clearance holes one by one. The fixing screws pass through the corresponding clearance holes and screw holes in sequence to fix the fixing sleeve to the bottom of the chassis.

[0013] The chassis is installed under the air hammer.

[0014] The middle of the chassis is provided with a central hole, the middle of the pressing block is provided with a mounting screw hole, and the bolt passes through the central hole from top to bottom and then is mounted on the pressing block.

[0015] The date numerals at the end of the cylindrical tail protrude by about 0.3 mm to 0.5 mm.

[0016] The advantages of the utility model are: 1. The year digits and month digits in the date push rod are detachable, and the digits are designed to protrude about 0.3mm~0.5mm, which can effectively control the clarity of the steel stamp and ensure that the terminal is not damaged. 2. The interior of the fixed sleeve is designed with four avoidance holes, which can be easily disassembled. 3. The date is split to the bottom of the four push rods, and only push rods with different digits need to be made. Compared with making an upper mold for each date, certain development and production costs can be saved; 4. The push rod of the year digit only needs to be replaced once a year, and the push rod of the month digit only needs to be replaced once a month. Only the push rod of the corresponding date digit needs to be replaced every day. When replacing, only the push rod needs to be pulled out and the corresponding push rod needs to be inserted vertically. It is convenient for disassembly and can save production time.

[0017] The utility model can solve the problems of unclear date, unrecognizable or damaged terminal, and affected use caused by the manual stamping method.

[0018] The utility model can solve the problem of low efficiency of manual steel stamping and improve work efficiency;

[0019] The spacing of the four positioning holes in the chassis is designed to be irregular, which, in conjunction with the fixing sleeve, can ensure the misalignment of the date push rod installed in the fixing sleeve.

[0020] The avoidance hole of the fixing sleeve can prevent the date lever from being difficult to remove after being installed on the tooling, thereby effectively improving the efficiency of replacing the date lever.

[0021] The date push rod is a cylinder on the upper part, and the lower part with the date is square. This method is easy to install and does not require fixing screws after installation. BRIEF DESCRIPTION OF THE DRAWINGS
