Moving plate machining method and moving plate machined through moving plate machining method

Abstract

The invention discloses a moving plate machining method and a moving plate machined through the moving plate machining method. The moving plate machining method comprises the following steps of (1) forming rivet holes in plates, wherein the rivet holes are formed in the corresponding positions of the middle supporting plate, the face plate and the bottom plate; (2) punching counter bores in the face plate and the bottom plate, wherein a punching machine and a punching die are used for performing counter bore inclined surface extrusion on the face plate and the bottom plate which are provided with the rivet holes; and (3) riveting the three laminates, wherein the three laminates, namely the face plate, the middle supporting plate and the bottom plate are sequentially laminated, then rivets are placed in the rivet holes, and flat heads on the two sides of the punching machine are used for performing punching to form flat rivet heads. According to the production and machining method, the depth consistency of the counter bores can be guaranteed, the concentricity consistency of the counter bores and the rivet holes can also be guaranteed, the overall flatness of the moving plate is higher, the strength of the moving plate can be improved, and the service life of the moving plate can be prolonged.

Description

technical field [0001] The invention relates to a processing technology for a shift car used for loading and unloading patients, in particular to a processing method for a moving plate used in a shifting car, and a moving plate processed by the processing method. Background technique [0002] At present, the medical lifting cart is used to move and transfer patients with inconvenient mobility before and after the operation, from the hospital bed to the transfer bed, and then from the transfer bed to the operating table or equipment requiring examination / treatment, or reverse transfer. Especially for patients with wounds or patients who have undergone severe spine, cervical spine, and thoracic spine operations, the birth of the medical lifting car reduces the labor intensity of medical staff and avoids the possibility of carrying the patient several times during the transfer period before and after surgery. The secondary injury that comes, such as may affect the wound or focu...

However, in the process of counterbore processing in step (2), since the plates of the panel and the bottom plate are too thin, it is difficult to ensure the depth of the artificially drilled counterbore holes to be consistent. , the two ends of the rivet will protrude from the counterbore, and even if the riveting installation cannot be realized, the rivet will also be exposed on the surface of the plate; even if the counterbore is drilled at one time with automatic equipment, the plate will be too thin and the plate will be uneven after clamping, and then processed Afterwards, the cou
