In order to ensure the consistency of the shell forming die table, in the prior art, punching dies distributed up and down are still used for construction at a side punching station, so that the preformed shell needs to be turned over before the side punching station by manpower or machinery, the side face of the preformed shell faces upwards, and the forming efficiency of the gas meter shell is seriously influenced in the process.

In the scheme, the first side punching device and the second side punching device are the upper die and the lower die which are distributed up and down, so that the consistency of the die table of the whole system can be ensured at first. The upper die comprises a second female die and a pushing piece, the second female die is used for being matched with a second male die on the lower die assembly, and the pushing piece is used for being matched with a sliding block on the lower die assembly.

In addition, after the work is finished, the shell still keeps the shape that the opening end faces downwards, so that the shell can be directly taken out to carry out the next shaping operation without being turned over again for resetting. Therefore, compared with the prior art, in the process of machining and forming the gas meter shell, the primary side punching can omit twice overturning of the semi-finished product shell, so that the manual operation is obviously reduced, and the machining efficiency is improved.

Furthermore, a side punching clamping plate is arranged on one side of the sliding block in the direction of the second male die, and the side punching head is arranged on the side punching clamping plate; a plurality of through holes are formed in the side punching clamping plate, and a punch at one side penetrates through each through hole; a first elastic part matched with the corresponding side punch is further arranged in the through hole, and when the side punch moves towards the direction of the second male die, the first elastic part deforms; the resetting device resets the sliding block when the upper die assembly moves upwards and leaves the contact with the lower die assembly; the second male die comprises a main body part with a wedge-shaped side face and a male sliding block in sliding fit with the wedge-shaped side face of the main body part, and the male sliding block is opposite to the side punch; the retreating mechanism is used for driving the main body part to lift.

According to the scheme, the side punching clamping plate firstly provides an installation station for the side punching head, so that the side punching head is convenient to disassemble and stable in connection; secondly, the side punch is prevented from directly contacting the sliding block, so that the side punch clamping plate is used as a buffer piece between the side punch and the sliding block, and the phenomenon that the sliding block is easily deformed and damaged due to the fact that instantaneous large reaction force is directly acted on the sliding block when the side punch works is avoided. The through holes on the side punching clamping plates correspond to the side punching heads one by one, and an elastic part one is matched between each side punching head and the corresponding through hole. When the side punch moves towards the direction of the second male die, namely when the sliding block is pushed by the pushing piece to work, the elastic piece deforms.

After the side punching operation is finished, the upper die moves upwards, the second female die is separated from the shell, the pushing piece is separated from the sliding block, at the moment, the upper die is completely separated from the corresponding lower die, and the limitation on the processed shell in the longitudinal direction is also removed. And then the slide block is reset by a resetting device, namely the slide block slides to a station before the upper die assembly descends, and the side punch is synchronously reset in the process and is withdrawn from the punched side punch hole, so that the limitation on the outer side of the processed shell is removed. This step not only facilitates the removal of the housing for further operations, but also provides for the side piercing of the next housing. In addition, after the side punching operation is completed, the punched hole formed on the surface of the shell is slightly concave, and the second male die cannot be taken out automatically through machinery in the state. Therefore, the scheme is provided with the retreating structure, and the second male die is arranged to be of a split type structure. Namely, the second male die comprises a main body part and a male sliding block, and the male sliding block is positioned at one end of the second male die facing to the direction of the side punch. The main body portion of the second male die is provided with a wedge-shaped side surface for sliding fit with the male slider, and certainly, the male slider can slide on the wedge-shaped side surface. In the scheme, after the punching operation is completed and the sliding block and the side punch retreat and reset, the retreat mechanism drives the main body part to lift, so that the male sliding block can be folded inwards for a certain distance under the coordination of the wedge-shaped side surface, and the outer convex part of the just-formed punched hole is avoided, thereby facilitating the taking out of the shell through a mechanical arm or any other existing mode; after the shell is taken out, the main body part is driven to reset by the position withdrawing mechanism, and the male sliding block is synchronously driven to reset.
