Problems solved by technology

The thrust is not high, the speed is slow, the accuracy is very low, and the burr is large.
At the same time, positioning one by one makes it difficult to guarantee product consistency, which directly leads to process complexity and increased production costs

Abstract

The invention discloses a perforating device of a lead acid storage battery shell. A cylinder (6) is installed at the bottom of a machine frame (7). The piston rod of the cylinder (6) is connected to one end of a lever (5). The other end of the lever (5) is connected to a mould sliding block (4). The mould sliding block (4) is movably installed on the top of the machine frame (7). A set of mould movable blocks (3) is installed on the mould sliding block (4). A perforating cutter (2) is installed on each mould movable block (3). A set of mould fixed blocks (1) is installed on the top of the machine frame (7). Guide holes are arranged on the mould fixed blocks (1). The guide hole of each mould fixed block (1) corresponds with one perforating cutter (2). According to the perforating device of the lead acid storage battery shell disclosed by the invention, the device is used for integrally locating and perforating at one time in a lever manner; the process is reliable and rapid; and the direct push perforating manner by locating one by one of a membrane cylinder is avoided, therefore, the device has the advantages of less burrs after perforating a product, higher consistency, simplified process and low cost.

Description

technical field [0001] The invention relates to a punching device, in particular to a punching device for a lead-acid storage battery shell. Background technique [0002] There is a key process in the production process of lead-acid batteries - through-wall welding, and its quality directly affects the performance of the battery. The solder joints of through-wall welding are on the battery case compartment inside the battery case. In order to connect the solder joints, the battery case needs to be drilled before through-wall welding. The less burrs on the battery case after drilling, the better, because burrs mixed in the through-wall solder joints will lead to false welding, resulting in quality problems such as unstable performance of the battery. However, the traditional technology is to punch holes one by one, position one by one, and adopt the working method of cylinder direct push. The thrust is not high, the speed is slow, the precision is very low, and the burr is ...
