As the utility model discloses an improvement, the mandrel is including left core lamella and right core lamella, the upper portion of left core lamella and right core lamella is formed with the clearance, the clearance has constituted the die cavity, the lower part of left side core lamella and right core lamella is constituted there is the mounting groove, die cavity and mounting groove are through a connecting hole intercommunication the toper piece is being fixed through the bolt in the mounting groove, the side of toper piece with the cell wall laminating of mounting groove, the top surface shape of toper piece with the bottom surface shape of die cavity is unanimous.

As a further improvement of the utility model, a copper buffer board is fixed at the bottom of the conical block.

As the utility model discloses a preferred the embedded a plurality of cooling tubes that are equipped with of anchor clamps, the cooling tube leads to pipe and links to each other with outside water pump, by the water pump to the cooling tube provides the cooling water.

Compared with the prior art, the utility model has the advantages of: set up the die cavity on independent mandrel, only need change the mandrel like this when die cavity inner wall wearing and tearing can, be convenient for change, in addition, the mandrel is formed by two core lamella combinations, the die cavity is also pieced together by two core lamellas, just so can be in separately when two core lamellas are in the detached state respectively to it processing, make the die cavity inner wall that the concatenation formed more accurate, the simultaneous processing degree of difficulty also reduces by a wide margin, in addition, set up the toper piece bottom the die cavity, the cooling tube has been set up in anchor clamps, can cushion the bearing capacity of die cavity inner wall and bottom surface, prevent the production of crackle.

Drawings

Fig. 1 is a schematic structural view of a manufacturing device of a chromium alloy wear-resistant bucket tooth in the embodiment of the present invention.

Detailed Description

The chromium alloy wear-resistant bucket tooth manufacturing equipment in the utility model is further explained with reference to the attached drawings.

As shown in the attached drawings, the embodiment is chromium alloy wear-resistant bucket tooth manufacturing equipment, which comprises a base 1 and a pressure plate 2 which are opposite up and down, wherein the pressure plate can approach or separate towards the base under the action of external driving force such as a press, the process of approaching towards the base is a mold closing process, the process of separating towards the base is a mold splitting process, a male mold 3 is formed at the bottom of the pressure plate, the contour of the male mold is consistent with the inner contour of a bucket tooth, the base comprises a clamp 4 which is annular, a mounting hole is formed in the center of the clamp, a core mold is fixed in the mounting hole, the outer wall of the core mold is attached to the hole wall of the mounting hole along the circumferential direction, the core mold comprises a left core piece 5 and a right core piece 6, a gap is formed at the upper parts of the left core piece and the right core piece, the gap is a cavity 7, the contour of the cavity is consistent with the outer contour of the bucket tooth, the bucket tooth is a hollow metal, at the moment, the shape of the metal component is different from the contour of the cavity (in order to reduce the deformation amount, the metal component can be preformed by a stamping mechanism outside to be close to the contour of the cavity), then the male die is started to be pressed downwards, when the male die is pressed downwards to a specified position, the metal component forms a bucket tooth shape under the extrusion of the male die and the inner wall of the cavity, namely when the male die is pressed downwards to the specified position, the shape of a gap between the metal component and the inner wall of the cavity is consistent with the standard bucket tooth shape, and then the metal component is separated from the cavity and taken out after being cooled.

In order to enable the contour of the inner wall of the cavity to be more accurate and more convenient to process, the cavity is formed by splicing the upper parts of the left core flap and the right core flap, when the cavity is processed, the left core flap and the right core flap are firstly processed in a separated mode and then folded, so that the open area of the cavity is large when the left core flap and the right core flap are independently processed, a processing tool can conveniently stretch into the cavity, particularly, when a narrow part at the bottom of the cavity is processed, the processing difficulty of the cavity is far lower than that of an integral cavity, and the processing tool is difficult to excessively stretch into the cavity due to the integral cavity.

In addition, a plurality of cooling pipes 12 are embedded in the fixture, and the cooling pipes are connected with an external water pump 13 through water pipes, and cooling water is supplied to the cooling pipes by the water pump. The principle is that when the metal component is formed, in order to change the shape of the metal component, the metal component needs to be heated at high temperature, and the flowability of the material of the metal component is improved, but the high-temperature metal component can transfer heat to a core die and a clamp which are made of die steel, so that the core die and the clamp can expand when heated, and the profile of a cavity changes.

The lower parts of the left core piece and the right core piece form a mounting groove, the cavity is communicated with the mounting groove through a connecting hole 8, a conical block 9 is fixed in the mounting groove through a bolt 10, the side face of the conical block is attached to the wall of the mounting groove, and the shape of the top face of the conical block is consistent with that of the bottom face of the cavity. A buffer plate 11 made of copper is fixed at the bottom of the conical block. Through the design of the structure, the pressure at the bottom of the cavity can be transmitted to the buffer plate through the conical block for buffering, and the generation of cracks at the bottom of the cavity can be avoided.

The above description is for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way, and modifications and variations can be made without departing from the principles of the present invention.
