In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a throat frock of tubular metal resonator, includes the base, one side on the base is provided with the fixed station, installs the motor in the fixed station, and the output of motor and the one end of connecting pipe are fixed, and the other end and the three-jaw chuck of connecting pipe are fixed, opposite side on the base is provided with the fixed plate, installs the hydraulic stem on the fixed plate, and the one end and the fixed block of hydraulic stem are fixed, and the middle part of fixed block is provided with the through-hole, and the installation is established to the through-hole interpolation and is fixed with the throat mould, and the outside cover in throat mould pyramis established the installation and is fixed with the cold air cover, the bottom installation of.
Preferably, the base is provided with a dovetail sliding groove, and a sliding block is connected in the dovetail sliding groove in a sliding manner.
Preferably, the center lines of the connecting pipe, the three-jaw chuck and the necking die are in the same straight line.
Preferably, one side of the cold air cover is connected with the output end of the air cooler through an air pipe, and the air cooler is arranged on one side of the base.
Preferably, the inner wall of the through hole on the fixing block is provided with a ring-shaped groove, and an electric heating ring is arranged in the groove.
The utility model has the advantages that: drive the tubular metal resonator through the motor and rotate, the electric heat ring heats the necking die simultaneously to make the tip of the tubular metal resonator that stretches into in the necking die be heated and slowly become soft, and under the promotion of hydraulic stem, the head that becomes soft gets into in the toper portion of necking die among the rotatory in-process, thereby makes the tip of tubular metal resonator carry out even throat.
Drawings
Fig. 1 is a schematic structural view of a necking tool for a metal pipe according to the present invention;
fig. 2 is a side view of a fixing block of a necking tool for a metal pipe according to the present invention;
fig. 3 is a schematic structural diagram of a necking die of the necking tool of the metal tube.
In the figure: the device comprises a base 1, a sliding block 2, a motor 3, a connecting pipe 4, a three-jaw chuck 5, a fixed block 6, a hydraulic rod 7, a necking die 8, an electric heating ring 9, a cold air cover 10 and an air cooler 11.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a necking tool for a metal tube comprises a base 1, a fixed table is arranged on one side of the base 1, a motor 3 is installed in the fixed table, an output end of the motor 3 is fixed with one end of a connecting tube 4, the other end of the connecting tube 4 is fixed with a three-jaw chuck 5, a fixed plate is arranged on the other side of the base 1, a hydraulic rod 7 is installed on the fixed plate, one end of the hydraulic rod 7 is fixed with a fixed block 6, a through hole is formed in the middle of the fixed block 6, an annular groove is formed in the inner wall of the through hole in the fixed block 6, an electric heating ring 9 is arranged in the groove, a necking die 8 is fixedly inserted in the through hole, a cold air hood 10 is fixedly installed on the outer side of the conical portion of the necking die 8 in a sleeved mode, one side of the cold air hood 10 is connected with an output end, the dovetail chute has been seted up on base 1, and sliding connection has slider 2 in the dovetail chute spout, and wherein the central line of connecting pipe 4, three-jaw chuck 5 and necking die 8 is in the collinear.
In the embodiment, when necking the metal pipe, one end of the metal pipe is inserted into the connecting pipe 4, the other end of the metal pipe is inserted into the necking die 8, and then the metal pipe is tightly gripped by the three-jaw chuck 5, wherein during necking, the size of the necking die 8 corresponds to the size of the metal pipe, if the diameter of the metal pipe is too large or too small, the fixing block 6 provided with the necking die with the corresponding size can be replaced, the metal pipe is driven to rotate by the motor 3, the necking die 8 is heated by the electric heating ring, the electric push rod 7 drives the fixing block 6 to slowly move towards the motor 3, the fixing block 6 moves under the action of the slider 2, so that the end part of the metal pipe extending into the necking die 8 is heated and slowly softened, and the softened head part enters the conical part of the necking die 8 in the rotating process under the push of the hydraulic rod 7, so that the end part of the metal pipe is uniformly necked, wherein the cold air hood 10 cools the conical part of the necking die, the thermal expansion deformation of the conical part is avoided, which is not beneficial to the uniformity of the necking of the metal tube.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
