detailed description The invention will be further clarified with reference to the accompanying drawings and specific embodiments, which are intended to illustrate the invention and not to limit the scope of the invention. Modifications of equivalent forms are intended to fall within the scope defined by the appended claims.

As shown in FIGS. 1 to 2, the pile tip maker of the present invention comprises a body, a lower mold 2 disposed on the body 1, an upper mold 3, a displacement actuator 4, a power mechanism 5, a clamping cylinder 6, and a control system 7. The lower mold mounting bracket 8, the clamp mounting bracket 9 and the clamp 91, the displacement actuator 4 is connected to the lower mold 2 and the upper mold 3, and the power mechanism 5 drives the displacement actuator 4 to move the upper mold 3 and the lower mold 2 in opposite directions. The body 1 includes an upper mold holder 31, a support leg 11 and a shaft base 12, and the displacement actuator 4 includes a first displacement actuator 41, a second displacement actuator 42 and a third displacement actuator 43. The first displacement actuator 41 is coupled to the upper mold holder 31, and the upper mold 3 is fixed to one end of the first displacement actuator 41. The lower mold mounting frame 8 is rotatably coupled to the shaft base 12 via the middle portion thereof, the lower mold 2 is attached to one end of the lower mold mounting frame 8, and the other end of the lower mold mounting frame 8 is coupled to the second displacement actuator 42. The jig mounting frame 9 is rotatably connected to the supporting leg 11 through one end thereof, and the jig 91 is attached to one end of the jig mounting frame 9 near the supporting leg 11, and the other end of the jig mounting frame 9 is connected to the third displacement actuator 43. The upper and lower molds and the upper and lower mold mounting frames 8 are detachably mounted, that is, the lower molds of different shapes can be replaced according to the shape of the pile tip, for example, a conical shape, a truncated cone shape or a prismatic shape. It should be noted that both the lower mold 2 and the upper mold 3 are inclined, and the lower end of the lower mold has a smaller end than the end with a larger cross section, and the larger end of the upper mold has a smaller cross section than the smaller cross section. One end. The lower mold 2 is provided with a pile tip fixing position, and the fixing position is one or several protrusions. Under the push of the displacement actuator, the clamp 91 moves toward the lower mold and one end of the clamp comes into contact with one end of the lower mold.

In use, the worker punches the pile tip raw material plate, places it on the lower mold, and fixes it through the fixed point of the pile tip, opens the control system to start the pile tip maker, and the power system (hydraulic pump) pushes the first displacement actuator downward. The end having the smaller cross section of the upper mold is first brought into contact with the end of the lower mold having a larger cross section. The contact faces of the upper and lower molds extend from the end with the smaller cross section to the end with the larger cross section. At the same time, the second displacement actuator pushes one end of the lower mold mounting frame downward to move the lower mold at the other end upward, and the third displacement actuator pushes one end of the clamp mounting frame downward to drive the other end. The clamp rotates downwards. One end of the clamp is first in contact with the smaller end of the lower mold and continuously extends toward the other end. Finally, the lower mold and the upper mold are close to each other, and the pile tip is formed by the action of the clamp. In this embodiment, the upper and lower molds are inclined so that one end of the first mold can be contacted first, rather than at the same time. It has been proved that the end of the first contact is higher than the simultaneous contact of the two ends, and the pile tip is damaged during the pressing process. In other embodiments, when the pile tip to be produced is conical or truncated, the shape of the lower mold is smaller than the shape of the finished product of the pile tip, or the outer surface of the lower mold is bent more than the bending degree of the finished product of the pile tip. For example, when a conical pile tip is to be produced, the curvature of the curved surface of the outer surface of the mold is greater than the cross-section of the finished product of the pile tip. The curvature of the line. In this way, the bending degree of the pile tip in the mold is slightly larger than the actual needs. When the upper and lower molds are opened, the pile tip is taken out, and the outer edge of the pile tip rebounds to the required degree of bending. If the size or bending degree of the lower mold is equal to the finished product of the pile tip, it is necessary to set multiple pressures in the control system or manually, thereby reducing the rebound of the outer edge of the pile tip and improving the yield of the pile tip. In general, the difference in the material of the pile tip is different, and the mold is generally less than 0.1% to 10% of the finished product. Or the curvature of the cross-section curve of the lower mold is greater than 0.1% to 5% of the curvature of the cross-sectional curve of the finished product of the pile tip.
