Description

Technical Field

[0001] This utility model relates to the field of valve cover stamping technology, specifically a valve cover stamping feeding and positioning fixture. Background Technology

[0002] The valve cover is a key component of a valve, primarily used to cover the valve body opening, forming a sealed pressure-bearing cavity together with the valve body. It also supports the valve stem and transmission mechanism, and houses the sealing components, ensuring reliable sealing of the valve under high-pressure environments. Valve covers are mainly produced through stamping, a processing method that uses a press and molds to apply external force to sheet metal, strip, pipe, and profiles, causing plastic deformation or separation to obtain a workpiece of the desired shape and size.

[0003] Chinese Patent Publication No. CN201792219U, authorized on April 13, 2011, discloses a battery positioning fixture, comprising a conveyor belt, a feeding and positioning push plate, a positioning pressure plate, and a fixture base. One end of the conveyor belt is connected to a stepper motor, and a feeding and positioning push plate is located on one side of the conveyor belt, connected to a feeding and positioning push plate cylinder. A baffle is located on the opposite side, fixedly connected to the fixture base. A positioning pressure plate is located in the middle of the conveyor belt, connected to a pressure plate cylinder that moves up and down. Front and rear clamping plates for battery positioning are located on both sides of the conveyor belt below the positioning pressure plate, respectively connected to front and rear cylinders for positioning. A set of upper and lower guide columns are connected below the positioning pressure plate. Due to the conveyor belt, feeding and positioning push plate, positioning pressure plate, and front and rear clamping plates for battery positioning, a group of workpieces can be neatly arranged, facilitating synchronous entry and processing of workpieces into the workstation, resulting in stable operation and high efficiency.
