Description

Technical Field

[0001] The utility model relates to the field of automobile sleeves, in particular to a double-side extrusion die for processing automobile sleeves. Background Art

[0002] Patent application number "201621459790.0," titled "A Special Split Socket for Automobiles," is a socket designed by our company. It requires a hexagonal hole on the left end and a quadrilateral hole on the right end. The traditional method involves punching a through hole in one end first, then the other. This is not only inefficient but also requires different equipment, which can easily lead to errors and make it difficult to guarantee product quality.

[0003] The patent "A fully automatic double-hole drilling machine and drilling method for automobile sleeves" with application number "202111642153.2" is used to drill transverse through holes in the radial direction of automobile sleeves and cannot be directly applied to this application. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a two-side extrusion die for processing automobile sleeves, which can simultaneously punch and form square holes and hexagonal holes of automobile sleeves, thereby improving efficiency and reducing processing errors caused by separate hole forming.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A double-sided extrusion die for processing automobile sleeves, comprising a first die head and a second die head, wherein the first die head and the second die head are arranged in mirror symmetry and are respectively fixed by a set of locking mechanisms;

[0007] The locking mechanism includes a limit seat, one side of which is open and can be detachably fixed to the mounting seat; a through hole is provided on the other side of the limit seat, and a limit ring is fixed to one end of the first die head or the second die head, and the limit ring is placed in the limit seat and is limited in movement along the axial direction; the other end of the first die head or the second die head extends out of the through hole.

[0008] A first gasket and a second gasket are respectively provided on the left and right sides of the limiting ring in the limiting seat, wherein a mounting hole is opened in the center of the first gasket, a spring is provided in the mounting hole, one end of the spring is pressed against the first die head or the second die head, and the other end is pressed against the mounting seat.

[0009] The first die head end is a hexagonal prism matched with the socket at one end of the automobile sleeve, and the second die head end is a quadrangular prism matched with the socket at the other end of the automobile sleeve.

[0010] The utility model provides a double-sided extrusion die for processing automobile sleeves, which has the following technical effects:

[0011] 1) By setting the first die head and the second die head on the left and right to match the end holes at both ends of the automobile sleeve, the first die head and the second die head are extended through their respective hydraulic cylinders, so that the end holes at both ends of the automobile sleeve can be punched at the same time, and the processing is completed in one time, which can improve efficiency and reduce the error of the two processing.

[0012] 2) By setting a locking mechanism, the first die head and the second die head can be detachably connected, so that the first die head and the second die head can be replaced according to the production of automobile sleeves of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1-2As shown, a double-sided extrusion die for processing automobile sleeves includes a first die head 1 and a second die head 2. The outer end of the first die head 1 is a hexagonal prism that matches the socket at one end of the automobile sleeve 4. The inner end of the first die head 1 is provided with a limit ring 3.4. The diameter of the limit ring 3.4 is larger than the main part of the first die head 1. The limit ring 3.4 is fixed to the left hydraulic cylinder through a set of locking mechanisms 3. The outer end of the second die head 2 is a quadrangular prism that matches the socket at the other end of the automobile sleeve 4. The inner end of the first die head 1 is provided with a limit ring 3.4. The diameter of the limit ring 3.4 is larger than the main part of the second die head 2. The limit ring 3.4 is fixed to the right hydraulic cylinder through a set of locking mechanisms 3. When the two sets of hydraulic cylinders are extended, the first die head 1 and the second die head 2 realize punching of the end holes along the axial direction at both ends of the automobile sleeve 4.

[0022] The locking mechanism 3 includes a limit seat 3.1. The limit seat 3.1 is a cap structure. One side of the limit seat 3.1 is open and the edge is provided with a flange. The limit seat 3.1 is detachably fixed to the mounting seat 3.2 by means of the flange and bolts. The mounting seat 3.2 is fixed to the corresponding hydraulic cylinder. A through hole 3.3 is provided on the other end face of the limit seat 3.1. The diameter of the through hole 3.3 is larger than the main body of the first die head 1 or the second die head 2, and the diameter of the through hole 3.3 is smaller than the diameter of the limit ring 3.4. The limit ring 3.4 is placed in the limit seat 3.1 and is restricted in its movement along the axial direction; the other end of the first die head 1 or the second die head 2 extends out of the through hole 3.3. The limit ring 3.4 can contact the end face of the mounting seat 3.2 at one end and contact the inner top surface of the limit seat 3.1 on the side away from the mounting seat 3.2 at the other end. In this way, after the limit seat 3.1 is installed, the first die head 1 or the second die head 2 is fixed.

[0023] Preferably, a first gasket 3.5 and a second gasket 3.6 are respectively positioned on the left and right sides of the limiting ring 3.4 within the limiting seat 3.1. The first gasket 3.5 is positioned on one side of the mounting seat 3.2, while the second gasket 3.6 is positioned away from the mounting seat 3.2. A mounting hole 3.7 is defined in the center of the first gasket 3.5. A spring 3.8 is positioned within the mounting hole 3.7. The spring 3.8 is compressed, with one end of the spring 3.8 resting on the first die 1 or the second die 2 and the other end resting on the mounting seat 3.2. The spring 3.8 has a high elastic modulus. Even if the first gasket 3.5 or the second gasket 3.6 is squeezed and deformed, the spring 3.8 can still provide a sufficient thrust to maintain the outward push of the first die 1 or the second die 2.
