When the stretching assembly comprises one or more stretching devices, the defect of overlarge one-time stretching forming load can be avoided, the stretching amount of each time is reduced, and the sheet material is gradually stretched into the required shell shape.

Further, a second side impact device is arranged between the stretching assembly and the second edge cutting device, and the second side impact device is used for forming patterns on the side surface of the shell.

In this scheme, first die holder keeps motionless, and the flitch can go on elevating movement above that. When the material plate to be processed is placed on the material pressing plate, the first female die descends, the material plate and the material pressing plate are pushed to move downwards, the ejector arranged on the first lower die base pushes against the middle of the material plate, and the edge part of the material plate continues to be punched to the periphery of the first male die along with the descending of the first female die, so that a shell structure with a downward open end is formed.

Furthermore, the inner surface of the first female die matched with the ejector is provided with a round angle, the middle part of the first female die is provided with a concave area matched with the ejector, and the concave area is provided with a round angle matched with the end face of the ejector.

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

In the scheme, the first side punching device and the second side punching device are also an upper die and a lower die which are distributed up and down, so that the consistency of a die table of the whole system can be ensured. 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. The sliding block slides on the sliding block seat, and the sliding block seat is fixed on the lower die holder. In the scheme, a side punch is arranged on the sliding block and faces the direction of the second male die. When the sliding block is pushed by the pushing piece to slide, the side punch can be driven to move towards the direction of the second punch. When the gas meter shell is used, the shell of the gas meter is not required to be overturned in a manual or mechanical mode, the shell is kept in a form that the open end is downward after the stretching and the trimming of the previous step, the shell is directly sleeved on a second male die in a lower die assembly, then the upper die assembly rapidly descends, a second female die is sleeved outside the shell, meanwhile, a pushing part rapidly pushes a sliding block to slide in the direction of the second male die, and the side punch is driven to instantaneously act on the side face of the shell, so that the side punching process can be realized. In addition, after the working is completed, the shell still keeps the shape that the open end faces downwards, so that the shell can be directly taken out to carry out the next shaping operation without overturning and resetting again. Therefore, compared with the prior art, in the machining and forming process of the gas meter shell, the scheme can omit twice overturning of the semi-finished shell by one side impact, thereby obviously reducing manpower operation and improving machining efficiency.

The die comprises a first punch, a second punch, a first punch, a reset device, a withdrawal mechanism and a second punch, wherein the first punch is arranged on one side of the slider, facing the direction of the second punch, the side punch is arranged on one side of the second punch, the side punch is arranged on the side punch, a plurality of through holes are formed in the side punch, each through hole penetrates through one side punch, an elastic piece I matched with the corresponding side punch is further arranged in the through hole, when the side punch moves towards the direction of the second punch, the elastic piece I deforms, the reset device resets the slider when an upper die assembly moves upwards and is out of contact with a lower die assembly, the second punch comprises a main body part with a wedge-shaped side face and a male slider in sliding fit with the wedge-shaped side face of the main body part, and the withdrawal mechanism is used for driving the main body part to lift.

According to the scheme, the side punch clamping plate firstly provides a mounting station for the side punch, is convenient to detach and ensures stable connection, and secondly avoids the side punch from directly contacting with the sliding block, so that the side punch clamping plate serves 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 an instantaneous larger reaction force acts on the sliding block directly when the side punch works is avoided. The through holes on the side punching clamp plate are in one-to-one correspondence with the side punches, and an elastic piece I is matched between each side punch and the corresponding through hole. When the side punch moves towards the direction of the second punch, namely when the slide block is pushed by the pushing piece to work, the elastic piece I deforms. In the whole punching process, the elastic piece cannot reset and always keeps a deformation state due to the limitation of the pushing piece. When the punching operation is finished and the upper die assembly moves upwards, the limit of the pushing piece on the sliding block is released, and the elastic piece can reset freely, so that the side punches can be driven to reset and the sliding block is synchronously driven to reset.

After the side punching operation is finished, the upper die is lifted upwards, the second female die is separated from the shell, the pushing piece is separated from the sliding block, and at the moment, the upper die is completely separated from the corresponding lower die, so that the limitation of the machined shell in the longitudinal direction is also relieved. And then the sliding block is reset by a reset device, namely the sliding block slides to a station before the upper die assembly descends, in the process, the side punches synchronously reset, and the side punches withdraw from the punched side punches, so that the limit on the outer side of the processed shell is removed. This step not only facilitates removal of the housing for the next operation, but also provides for side punching 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 is not easy to be automatically taken out from the second male die by a machine in the state. Therefore, the scheme is provided with the backset structure, and the second male die is arranged into a split 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 the direction of the side punch. The body of the second punch is provided with a wedge-shaped side surface for sliding engagement with the male slider, which, of course, is capable of sliding on the wedge-shaped side surface. In the scheme, when punching operation is completed, after the sliding block and the side punch are retracted and reset, the main body part is driven by the retraction mechanism to lift, so that the male sliding block can be retracted inwards for a certain distance under the cooperation of the wedge-shaped side surface, the outer protruding part of the punched hole just formed is formed, the shell is conveniently taken out through a mechanical arm or any other existing mode, and after the shell is taken out, the main body part is driven by the retraction mechanism to reset, and the male sliding block is synchronously driven to reset.
