Problems solved by technology
[0002] In the existing packaging steel drums, when the top is covered with a sealing cover, the top flanging of the packaging steel drum must be rounded first, and then the threads are cut on the flanging, but the accuracy and strength of the threads are difficult to meet the requirements. The fit is unstable, so it is easy to cause the contents to leak during use

Embodiment Construction
[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0029] Such as Figure 1-4 As shown, a packaging steel drum includes a drum body 1, an end cap hoop 2 is provided on the top of the drum body 1, and a threaded hole 3 for connecting a sealing cap is opened on the end cap hoop 2.
[0030] The end cap hoops 2 include two, and the two end cap hoops 2 are ring-shaped, and the two ends of the two end cap hoops 2 are fixedly connected.
[0031] Each of the end cap hoops 2 includes a horizontal ring 21 , a vertical ring 22 and a spherical ring 23 fixedly connected to each other, and the vertical ring 22 and the spherical ring 23 are respectively located at two ends of the horizontal ring 21 . .
[0032] The horizontal ring 21 abuts against the top of the barrel body 1, t...

The invention relates to a packaging steel drum comprising a drum body. The top of the drum body is provided with an end cap hoop, and the end cap hoop is provided with a threaded hole for being connected a sealing cover. A machining technology for the packaging steel drum comprises the steps that 1, a steel coil is uncoiled and cut into a required steel plate on a plate shearing machine; step 2,the steel plate is crimped into a side wall of the drum body 1; 3, a circular shape conforming to the bottom wall of the drum body 1 is punched on a punching machine, and the circular shape is fixedlyconnected to the side wall in the step 2; and 4, the side wall of the top of the drum body is subjected to cold pressing through a specific spherical ring die, and a spherical ring groove is machined. The packaging steel drum and the machining technology have the beneficial effects that threads are conveniently machined, and sealing and reliability of the packaging steel drum are made reliable.
Description
technical field [0001] The invention relates to a packaging device, in particular to a packaging steel drum and its processing technology. Background technique [0002] In the existing packaging steel drums, when the top is covered with a sealing cover, the top flanging of the packaging steel drum must be rounded first, and then the threads are cut on the flanging, but the accuracy and strength of the threads are difficult to meet the requirements. The fit is unstable, so it is easy to cause leakage of the contents during use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a packaging steel drum, which facilitates the processing of threads and makes the sealing of the packaging steel drum reliable. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a packaging steel drum, including a drum body, the top of the drum body is provided with an end ...
