Description

Technical Field

[0001] The utility model relates to the technical field of valve stem processing, in particular to a blanking machine for valve stem processing. Background Art

[0002] The valve stem is an important part of the valve, used for transmission, connected to the actuator or handle, and directly drives the valve core to move or rotate to achieve the valve opening or closing or regulating effect:

[0003] After the valve stem is manufactured, it needs to be discharged to a dedicated discharge machine. Some existing discharge methods use a manipulator with a mechanical gripper to clamp the valve stem for discharge, while others use a hopper to discharge the valve stem directly from the hopper.

[0004] These conventional valve stem discharging methods have some minor problems. For example, the manipulator and mechanical gripper are expensive, the discharging hopper cannot discharge the valve stem regularly, and if the design angle of the discharging hopper is poor, it will hit the valve stem. For this reason, we propose a valve stem processing discharging machine. Utility Model Content

The upper surface of the upper displacement plate is provided with evenly distributed fixed horizontal bars. The upper surfaces of the three fixed horizontal bars are provided with evenly distributed semicircular arc grooves. It is low in cost and can realize flexible conduction. At the same time, it can also realize intermittent and regular blanking during the valve stem processing and blanking process.

[0009] Furthermore, the unloading mechanism also includes an abutment interface, a first mounting frame and a limiting semi-arc clamping ring. The upper surface of the upper displacement plate is provided with evenly distributed abutment interfaces, and the first mounting frame is fixedly connected between the left and right inner walls of the workbench. The upper end of the first mounting frame is provided with evenly distributed limiting semi-arc clamping rings, which are staggered with the abutment interfaces, and the limiting semi-arc clamping rings correspond to the front and rear positions of the semi-circular arc grooves to realize the function of flexible material guiding.

[0010] Furthermore, it also includes a right-side avoidance opening, which is evenly opened at the right end of the discharge plate, and the right-side avoidance opening corresponds to the left and right positions of the upper displacement plate to realize the discharge function.

[0011] Furthermore, it also includes a transverse cylinder, which is arranged on the lower side of the right surface of the workbench, the telescopic end of the transverse cylinder is fixedly connected to the right end of the bottom displacement plate, and the air inlet of the transverse cylinder is connected to an external air pump to provide power for left and right position adjustment.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the valve stem processing blanking machine has the following advantages:

[0016] When it is necessary to carry out valve stem cutting operation, the prepared valve stem falls into the inside of the semicircular arc groove on the far right through the feed plate. At this time, the external air pump is regulated, the horizontal cylinder is operated, and the telescopic end of the horizontal cylinder is extended, which can push the bottom displacement plate to adjust the left and right position.
