Abstract
The invention discloses a cutter for processing sealing face of a gate valve. The cutter comprises a cutter arbor and a cutter bit mounted on the cutter arbor; the cutter arbor is provided with a radial through hole; the cutter bit penetrates through the radial through hole; the axial end head of the cutter arbor is provided with an axial screw hole communicating with the radial through hole; and a fastening bolt for fastening the cutter bit is arranged in the axial screw hole. When the cutter disclosed by the invention is used for processing two sealing faces of a gate valve, the valve body may not be turned over; and the process for the two sealing faces can be completed only by moving the cutter, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of cutter apparatus that is used for metal processing, relate in particular to a kind of cutter that is used to process the slide valve sealing surface.
Background technology
The position that valve body and valve plate are sealed and matched is a sealing surface, and the sealing surface of slide valve is owing to need be sealed and matched with the edge, two sides of valve plate, so sealing surface is two ring surfaces that are parallel to each other.
In the prior art processing slide valve sealing surface the time, can utilize engine lathe, valve body is fixed on the lathe spindle, utilize cutter at first to process one of them sealing surface, valve body then takes off and overturns, utilize cutter to process another sealing surface again, be equivalent to two procedures, reduced the efficient of valve body processing.
Summary of the invention
The invention provides cutter a kind of simple in structure, easy to use, when two sealing surfaces of processing slide valve, need not the valve body that overturns, only just can finish the processing of two sealing surfaces, improved production efficiency by the motion of cutter.
A kind of cutter that is used to process the slide valve sealing surface, comprise knife bar and the cutter head that is installed on the knife bar, described knife bar is provided with radial direction through hole, described cutter head runs through this radial direction through hole, the axial end head position of described knife bar is provided with the axial screw that is communicated with radial direction through hole, is provided with the fastening bolt that is used for fastening cutter head in this axial screw.
After knife bar stretched into valve body together with cutter head, cutter head radially stretched between two sealing surfaces of valve body, and when the knife bar axially-movable, cutter head can contact and cut with two sealing surfaces respectively, to finish the processing of sealing surface.
The head of described cutter head and afterbody extend out from the two ends of radial direction through hole respectively, and bending formed bending part after afterbody extended radial direction through hole.Described bending part pastes the outer wall at knife bar.Bending part can prevent that cutter head from deviating from knife bar.
The head of described cutter head is trapezoidal, and this trapezoidal bottom is the blade that is used to cut.
Cutter of the present invention need not the valve body that overturns when two sealing surfaces of processing slide valve, only just can finish the processing of two sealing surfaces by the motion of cutter, has improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of cutter of the present invention;
Structural representation when Fig. 2 processes the slide valve sealing surface for cutter of the present invention.
The specific embodiment
Referring to Fig. 1, a kind of cutter that is used to process the slide valve sealing surface of the present invention, comprise knife bar 1, knife bar 1 is provided with radial direction through hole, cutter head runs through this radial direction through hole, the axial end head position of knife bar 1 is provided with the axial screw that is communicated with radial direction through hole, is provided with the fastening bolt 3 that is used for fastening cutter head in this axial screw.
The head 4 and the afterbody 2 of cutter head extend out from the two ends of radial direction through hole respectively, and afterbody 2 extends bending behind the radial direction through hole and forms bending part and paste outer wall at knife bar 1, and bending part can prevent that cutter head from deviating from knife bar 1.
The head 4 of cutter head is trapezoidal, and this trapezoidal bottom is the blade that is used to cut.
Referring to Fig. 2, valve body rotation during use, after knife bar stretches into valve body together with cutter head, the head 4 of cutter head radially stretches between the sealing surface 5 and sealing surface 6 of valve body, when the knife bar axially-movable, the head 4 of cutter head can contact and cut with sealing surface 6 with sealing surface 5 respectively, finishes the processing of two sealing surfaces of valve body.
Cutter of the present invention need not the valve body that overturns when two sealing surfaces of processing slide valve, only just can finish the processing of two sealing surfaces by the motion of cutter, has improved production efficiency.
