Abstract

The utility model discloses a protective fence for a stamping production line, which is applied to the technical field of stamping production and comprises a stand column, wherein both sides of the stand column are bolted with a fixed enclosure frame, the inside of the fixed enclosure frame is connected with a lifting fence in a sliding manner, the bottom of the stand column is bolted with a motor, and the output end of the motor is bolted with a first bevel gear. The motor drives the threaded rod to rotate and be engaged with the thread sleeve thread, so that the lifting rod can support the lifting fence to slide up and down in the fixed enclosure frame. Therefore, the protective fence can be adjusted according to the height of the machine of the stamping production line, and foreign matters are prevented from being outwards collapsed, and workers or equipment outside the fence are prevented from being damaged. The sliding plate is pushed upwards to overcome the elasticity of the spring, so that the inserted link slides upwards to the top of the bolt seat, and the inserted link is driven to slide and be inserted into the bolt seat by utilizing the resilience force of the spring to splice the protective fence. Therefore, the protective fence does not need to be lifted, and the actual operation is convenient.

Description

Protective fence for stamping production line Technical Field The utility model belongs to the technical field of stamping production, and particularly relates to a protective fence for a stamping production line. Background The existing automatic stamping production line generally adopts a mechanical arm to replace the traditional manual feeding and discharging, so that manual operation is not needed in the production process. In order to ensure the safety of automatic production of the machine, a protective fence is used at the periphery of the production line to separate the machine from the passageway, so that non-professional personnel are prevented from approaching the machine to cause injury. At present, the Chinese utility model with the bulletin number of CN210648223U discloses a protection device for an automatic stamping production line. The prior protective fence can splice a plurality of fences together according to the length of the production line, so that the fences can be suitable for different production lines. However, when the fences are spliced, one fence needs to be lifted to enable the side inserted bars to be inserted into the bolts of the other fence, and the splicing mode is troublesome, and is time-consuming and labor-consuming. Meanwhile, the height of the existing protective fence is not adjustable, so that the machine cannot be completely enclosed when a certain machine is enclosed in a high production line. When the machine is used for stamping, part of foreign matters are easy to collapse out from the place which is not surrounded by the top of the fence, so that the workers or equipment outside the fence are injured. Disclosure of utility model The utility model aims to provide a protective fence for a stamping production line, which has the advantages of being convenient for mutually assembling the protective fences and having the function of lifting and adjusting the protective fences according to the height of a machine. The technical aim of the utility model is achieved through the following technical scheme that the protective fence for the stamping production line comprises a stand column, wherein both sides of the stand column are respectively bolted with a fixed enclosure frame, the inside of the fixed enclosure frame is connected with a lifting fence in a sliding manner, the bottom of the stand column is bolted with a motor, the output end of the motor is bolted with a first conical gear, the inside of the stand column is rotationally connected with a threaded rod, the surface thread of the threaded rod is sheathed with a thread bush which is connected with the stand column in a sliding manner, the bottom of the threaded rod is bolted with a second conical gear which is meshed with the first conical gear, and both sides of the surface of the thread bush are welded with lifting rods which are matched with the lifting fence. By adopting the technical scheme, the motor drives the threaded rod to rotate and be engaged with the thread sleeve thread, so that the lifting rod can support the lifting fence to slide up and down in the fixed enclosure frame. Therefore, the protective fence can be adjusted according to the height of the machine of the stamping production line, and foreign matters are prevented from being outwards collapsed, and workers or equipment outside the fence are prevented from being damaged. The sliding plate is pushed upwards to overcome the elasticity of the spring, so that the inserted link slides upwards to the top of the bolt seat, and the inserted link is driven to slide and be inserted into the bolt seat by utilizing the resilience force of the spring to splice the protective fence. Therefore, the protective fence does not need to be lifted, and the actual operation is convenient. The utility model is further characterized in that two sides of the fixed enclosing frame, which are far away from each other, are respectively provided with a bolt seat and a bolt rod which are connected with each other in a sliding way, one side of the bolt seat, which is close to the upright post, is welded with the fixed enclosing frame, the top of the bolt rod is welded with a pull plate, one side of the pull plate, which is close to the upright post, is welded with a sliding plate which is connected with the inside of the fixed enclosing frame in a sliding way, and the top of the sliding plate is bolted with a spring which is fixedly connected with the fixed enclosing frame. By adopting the technical scheme, the latch rod is driven to be inserted into the latch seat in a sliding manner by utilizing the resilience force of the spring to splice the protective fence, so that the protective fence is not required to be lifted. The lifting rod is further provided with limiting plates which are clamped with the lifting rail in a welded mode on one sides, far away from the threaded sleeves, of the lifting rods. By adopting the technical scheme, the lifting fence is limite
