[0020] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of the relative relationship, without substantial change of the technical content, should also be regarded as the scope of the implementation of the utility model.

[0021] like Figure 1-5 As shown, the utility model provides an embodiment of a head shrinking machine embedded device for retaining a part cavity, comprising a fixing part 100 and a supporting part 200. The fixing part 100 is fixed to the head shrinking machine 300 by means of a threaded connection. The supporting part 200 can be fixedly connected to the fixing part 100 by means of a threaded connection, a plug-in connection or a clamping connection along the axial direction, so that one end of the supporting part 200 is embedded in the head shrinking machine, and the supporting part 200 matches the cavity of the part. The external shape of the supporting part 200 is preferably a rectangle to ensure that when the cavity part is inserted into the supporting part 200, the end of the cavity part is located at the processing position of the head shrinking machine. Among them, the overall structure of the fixing part 100 is preferably an H-shaped steel plate to improve the structural stability of the fixing part 100. The fixing part 100 and the supporting part 200 are connected in a T-shaped structure as a whole, and the material of the supporting part 200 is preferably a steel plate. Grooves 210 are axially provided at the top and bottom of the support portion 200, and the grooves 210 match the convex ribs 210 at the ends of the upper and lower shrinking plates of the shrinking machine so that the remaining material of the part can be pressed into the grooves 210 through the convex ribs 310 during the shrinking process.

[0022] When in use, the support part 200 is fixedly mounted on the fixing part 100 to form an assembly, and the assembly is fixed to the working part of the head shrinking machine by bolts, so that one end of the support part 200 is embedded in the head shrinking machine 300 to complete the installation of the embedded device. Press the power button of the head shrinking machine to start the head shrinking machine, so that the four circumferentially distributed head shrinking plates of the head shrinking machine are separated. Then, the rectangular cavity part is sleeved on the support part 200 at a preset position, and the head shrinking plate start button of the head shrinking machine 300 is pressed to drive the four head shrinking plates to move toward the center, and the end of the part is squeezed in the up, down, left and right directions to reduce the external dimensions of the part. After the head shrinking is completed, the four head shrinking plates automatically separate to the surroundings. It should be noted that during the shrinking process, the outer dimensions of the parts are squeezed and reduced, resulting in excess material. The excess material will accumulate at the four corners of the cavity parts, i.e., material extrusion occurs. Under the action of the ribs of the upper and lower shrinking plates of the shrinking machine, the excess material enters the groove of the support part 200 under pressure, so as to achieve the reduction of the outer dimensions of the rectangular cavity parts while still maintaining the shape of the internal cavity, and at the same time prevent material extrusion from occurring at the four corners of the rectangular cavity parts.

[0023] In one embodiment, if Figure 5 As shown, a limiting portion 400 is provided at one end of the groove 210 close to the fixing portion 100. When the rectangular cavity part is inserted into the supporting portion 200, the end of the rectangular cavity part abuts against the limiting portion 400, so that the rectangular end is located at a predetermined position in the shrinking machine to prevent the shrinking length from being too large, and at the same time, it can ensure that the rectangular cavity part will not be displaced axially during the shrinking process.

[0024] In one embodiment, the support portion 200 includes a base 220 and a support frame 230 . The support frame 230 is fixed to the base 220 . A plurality of ribs 240 are disposed at the connection between the support frame 230 and the base 220 to enhance the overall structural strength.

[0025] In one embodiment, the limiting portion 400 includes a plurality of abutment members 410, each of which is circumferentially distributed on the side wall of the support frame 230. Specifically, the abutment member 410 is preferably a detachable bolt or a blocking block, and when the rectangular cavity part is inserted into the support frame 230, the edge of the abutment member 410 abuts against the end of the rectangular cavity part, thereby limiting the position of the part and preventing the shrinkage length from being too large.

[0026] Furthermore, grooves 210 are provided at the top and bottom of the support frame 230 along the axial direction until they extend to the end of the support frame 230 away from the base 220. During the shrinking process, the rectangular cavity part is squeezed around and the excess material is squeezed into the groove of the support frame 230 under the action of the convex ribs to prevent the four corners of the rectangular cavity part from being squeezed.

[0027] By fixing the fixing part of the utility model to the shrinking machine, the cavity part is sleeved on the supporting part during use, and the shrinking plate of the shrinking machine shrinks the part in the up and down and left and right directions. In this process, the excess material generated by the shrinking of the part's outer dimensions is pressed into the groove of the supporting part by the convex ribs at the ends of the shrinking plate in the up and down directions, so as to achieve the reduction of the outer dimensions of the rectangular cavity part while still maintaining the shape of the internal cavity, and prevent the occurrence of material extrusion.

[0028] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
