Problems solved by technology

At present, the traditional method for closing the head is mostly to use the closing machine to squeeze and bend. During the processing, the end of the head is supported by the vertical support force of the round roller on the work table, and at the same time it is laterally squeezed by the outer mold wheel. The pressure causes serious outward inclination of the closing part, which increases the closing part. In order to solve this problem, the size of the head is made small in advance when making the head to offset the increase in the closing part caused by the closing process. This method is difficult to ensure the accuracy of the closing size, and it is easy to cause the head to be scrapped; in addition, the thickness of the plate at the closing part of the head is generally 2mm to 5mm, and the rigidity is not enough. If they are not on the same plane, the height of the closing part will be inconsistent, and the quality of the closing will be low

Embodiment 1

[0024] refer to figure 1 As shown, the present invention provides a closure device for closing the closure head 60. The closure device includes a top plate 10 and a bottom plate 20 arranged oppositely, an upper pressing mechanism 30 arranged on the top plate 10, and a The lower pressing mechanism 40 and the closing mechanism 50 on the base plate 20.

[0025] The upper pressing mechanism 30 includes an upper pressing oil cylinder 31 installed on the top plate 10 and an upper pressing member 32 arranged at the output end of the upper pressing oil cylinder 31, and the cylinder end of the upper pressing oil cylinder 31 is rotatably mounted on On the top plate 10 , the upper pressing member 32 is fixedly arranged on the output end of the upper pressing oil cylinder 31 , and the upper pressing member 32 is driven to rotate by the rotation of the upper pressing oil cylinder 31 .

[0026] The lower pressing mechanism 40 includes a first motor 41 fixedly installed on the base plate 20...

Embodiment 2

[0040] The difference between this embodiment and Embodiment 1 is that: the end of the cylinder body of the upper pressing cylinder 31 is fixed on the top plate 10, and the upper pressing member 32 is rotatably installed on the output end of the upper pressing oil cylinder 31 . Driven by the lower pressing mechanism 40, the upper pressing member 32 at the output end of the upper compression oil cylinder 31 is driven to rotate.

[0041] A closing device for a head of the present invention, compared with a traditional closing device, fixes the closing head 60 between the upper pressing mechanism 30 and the lower pressing mechanism 40, so that the end to be closed of the closing head 60 is only subjected to external pressure. The extrusion force of the mold wheel 524 eliminates the support force in the vertical direction and avoids the severe outward tilt of the closing part. At the same time, it also avoids the situation that the height of the closing part is inconsistent due to...

Abstract

The invention discloses a closing device for a sealing head. The closing device is used for closing the sealing head and comprises a top plate, a bottom plate, an upper pressing mechanism, a lower pressing mechanism and a closing mechanism, wherein the top plate and the bottom plate are oppositely arranged, the upper pressing mechanism is arranged on the top plate, and the lower pressing mechanism and the closing mechanism are arranged on the bottom plate. By means of the closing device for the sealing head, compared with a traditional closing device, the sealing head is fixed to the position between the upper pressing mechanism and the lower pressing mechanism, so that the end, to be closed, of the sealing head is only subjected to extruding force of an outer die wheel, vertical supporting force is removed, and serious outward tilting of a closed part is avoided; and meanwhile the situation that the height of the closed part is inconsistent due to warp caused by insufficient rigidity of the sealing head is avoided, the closing precision is ensured, the closing quality is improved, and the scrap rate of products is decreased. The invention further provides a closing method adopting the closing device.

Description

technical field [0001] The invention relates to the closing processing technology of a head, in particular to a closing device and a closing method of a head. Background technique [0002] The head is an indispensable and important part of pressure vessel equipment in many industries from petrochemical, atomic energy to food and pharmaceutical. As the end cover on the pressure vessel, it is a main pressure-bearing part of the pressure vessel. The stainless steel end caps on the oxygen and liquid nitrogen tanks also use this type of head. At present, the traditional method for closing the head is mostly to use the closing machine to squeeze and bend. During the processing, the end of the head is supported by the vertical support force of the round roller on the work table, and at the same time it is laterally squeezed by the outer mold wheel. The pressure causes serious outward inclination of the closing part, which increases the closing part. In order to solve this problem,...
