Description

Electrode Terminal Forming Apparatus for Storage Battery {An Electrode Forming Apparatus For Storage Battery}

The present invention relates to an electrode terminal forming apparatus for a battery that is mounted on a battery and used as an electrode terminal.

To explain this in more detail, it is possible to vertically guide the punch operation plate provided with the punch holder by the guide supporting rod installed between the upper support plate and the lower fixing plate, and to guide the lower side of the punch operation plate. It has a punch support plate which is operated up and down along the rod and has a stopper installed on the bottom, but between the punch operation plate and the punch support plate, the hydraulic or gas shock bar can compensate for the stopper wear due to continuous use and the impact when punching is performed. It can be operated more smoothly while mitigating, and it is possible to engage and separate the molding brackets which are symmetrically divided on both sides at the center of the lower fixing plate by the cylinder, but can be operated (movement) in a straight line by the guide means. It is an improvement.

Secondary batteries, which are largely classified into automobiles and industries, can be used repeatedly by charging. Electrode terminals for inputting and outputting electricity are provided at both ends of the batteries used in this way, and the present invention is used as described above. An object of the present invention is to provide an apparatus for manufacturing an electrode terminal.

In preparing the electrode terminal as described above, it was conventionally manufactured by casting to inject a molten metal into a mold to be molded.

However, in the method of manufacturing by casting, care must be taken to prevent the mixing of air in the process of pouring the molten metal melt by high heat into the mold, there was a problem that can not block the inflow of air, There was a problem that the electrode terminal was easily broken by the weak external force due to the strength deteriorated by the pores generated in the tissue, and there was a problem that the oxidation phenomenon rapidly progressed and the electrical conductivity was significantly decreased. There was a problem that safety accidents frequently occur as the hot molten metal is scattered to the outside of the mold when filling to the.

In order to solve such problems as above, I propose a battery electrode terminal manufacturing apparatus according to Patent Application No. 66-4750 and Utility Model Registration Application No. 96-3059.

It is equipped with a punch to press and shape the workpiece cut to a certain length to the upper insert die which is operated up and down, the lower insert is installed on the lower side of the upper insert die, the lower insert with a molding portion to set the workpiece in the center A die is provided, and both sides of the downward insert die are provided with slide plates formed to face each other, and are formed to be coupled / separated while the slide moves by the operation of each cylinder.

However, in the conventional battery electrode terminal manufacturing apparatus formed as described above, a phenomenon in which the slide plate is pushed outward due to the pressure exerted by the punch when molding the workpiece is formed by the punch, thereby forming the molded article accurately. There was a problem that there was no problem, and therefore there was a problem that the molded object could not be easily molded.

In order to solve such a problem, I proposed Utility Model Registration No. 155514, "Slide fixing plate of the electrode terminal manufacturing apparatus of a battery."

It is formed in the same manner as the battery electrode terminal manufacturing apparatus according to the above-mentioned patent application No. 66-4750 and Utility Model Registration Application No. 96-3059 described above so that it can be operated by cylinders on both sides of the upper side of the insert die. In the state in which the workpiece is shaped by a punch in the state in which the slide plate is coupled, the fixed fixture is lowered by the cylinder to support the combined slide plate so as not to be pushed outward.

However, this has a problem in that the structure and the operation principle are complicated because the slide plate fixing device equipped with a fixture on the rod of the cylinder is installed separately on both sides of the upper insert die so that the slide support plate is not pushed outward.

In addition, the conventional patent application No. 66-4750 and Utility Model Registration Application No. 96-3059, "battery electrode terminal manufacturing apparatus" and Utility Model Registration No. 155514 "slide fixing plate of the electrode terminal manufacturing apparatus of the battery" is a punch. Since there is no device for vertically supporting and guiding the inserted insert die, there is a problem of shaking when the upper insert die is lowered together with the punch. As a result of shaking, there was a problem in that the molded object could not be molded accurately and precisely.

In addition, since there is no device to alleviate the impact generated when punch punches the workpiece, the impact generated during punching is transferred to the punch and the device, and the punch is easily worn and damaged. The mechanical device has a problem in that vibrations are severely generated by impacts, and thus the moldings cannot be molded accurately and precisely.

The present invention is to provide an electrode terminal forming apparatus for a battery further improved to solve the above problems.

The present invention is to fix the punch operation plate with a punch holder to the upper support plate and to install the guide support rod on the bottom of the punch operation plate to be inserted into the guide support tube fixed to the lower fixed plate to operate the punch support plate vertically up and down The lower side of the punch operation plate is provided with a punch support plate which is operated up and down along the guide supporting rod and the stopper is installed on the bottom, and a hydraulic or gas showbar is provided between the punch operation plate and the punch support plate.

It is provided with a pair of stoppers directly installed on the bottom of the punch support plate to be operated up and down together with the punch support plate, and are divided and installed to correspond to both sides of the center of the lower fixing plate is coupled and separated by the cylinder The molding tool aims to provide a further improved electrode terminal forming apparatus for a battery to be guided by a guide means.

Another object of the present invention is to vertically guide the punch operation plate provided with the punch holder in the guide support rod provided between the upper support plate and the lower fixing plate to operate vertically while preventing shaking, The lower side is provided with a punch support plate provided with a stopper on the bottom side, but a hydraulic or gas shovel is provided between the punch operation plate and the punch support plate to smoothly operate the machine and reduce the impact when punching. To provide an electrode terminal forming device for a battery that can alleviate the impact.

Another object of the present invention is to install a pair of stoppers on the bottom of the punch support plate to be operated up and down together with the punch support plate, and to prevent the molding tool from being pushed out when punching. It is possible to precisely mold the electrode terminals so that the molding brackets, which are symmetrically divided on both sides from the center of the lower fixing plate, can be coupled and separated by a cylinder, but can be operated (movement) in a straight line by the guide means. The present invention provides an improved electrode terminal forming apparatus for a storage battery.

In addition, a pair of stoppers 14 are mounted on the bottom of the punch support plate 12 so as to prevent the molding tool 20, which will be described later in detail, from being retracted when forming by punching. The support bracket 16 is fixed to the bottom of the punch support plate 12 on the outside of the support 14, and the support bolt 17 is screwed to support the stopper 14 by the support bolt 17. The nut 18 is coupled to the support bolt 17 to fix the support bracket 16 to the support bracket 16. The stopper 14 forms a housing made of metal and attaches a pad to the bottom of the housing.

On the other hand, the upper surface of the lower fixing plate (2) is provided with a pair of molding brackets 20 in which the molding die is divided into two, and the rods 22 of the cylinders 21 installed on each outside are connected to operate the cylinders 21. It is possible to couple and separate the molding brackets 20 opposed to each other, by forming a guide rail 23 in the rod 22 and inserted into the guide block 24 fixed to the upper surface of the lower fixing plate (2) The guide rail 23 is allowed to slide along the guide block 24.

An ejector 30 for discharging the molded object to the outside was installed at the lower side of the molding part formed in the center of the lower fixing plate 2.

The operation relationship will be described below.

As illustrated in FIG. 1, the punch fixing plate 4 and the upper support plate 3 on which the punch holder 11 is installed are located at the top dead center, and the lower fixing plate 2 is disposed in a state in which the opposite molding dies 20 are spaced apart. Put the object to be molded into the molding part and load it.
