The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0055] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] The following is a detailed description of various embodiments of the present invention in conjunction with the accompanying drawings.

[0057] See also Figure 1 , Figure 1 2 is a schematic diagram of a workpiece suitable for the present invention. Specifically, the workpiece 200 includes a main body 210 and a convex body 220 connected to one side of the main body 210. The material of the workpiece 200 is ductile.

[0058] For ease of description, Figure 2 , Figure 3 and Figure 5A three-dimensional coordinate system is added, the X-axis direction is the first direction, the Y-axis direction is the second direction, and the Z-axis direction is the third direction. Among them, the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0059] See also Figure 2 and Figure 3 The embodiment of the utility model provides an extension jig 100 for extending a convex body 220 in a workpiece 200. The extension jig 100 includes a bearing seat 110 and a side pusher 120. The bearing seat 110 includes a bearing member 111 and a stopper 112 disposed on the bearing member 111. The bearing member 111 has a bearing surface 111a for bearing a main body 210. The bearing surface 111a is parallel to a plane formed by an X-axis direction and a Y-axis direction. The bearing member 111 is provided with a guide groove 111b extending to the bearing surface 111a and inclined relative to the bearing surface 111a. The guide groove 111b is disposed on one side of the stopper 112 in the X-axis direction. The side pusher 120 is slidably disposed in the guide groove 111b. When the side pusher 120 slides along the guide groove 111b, it simultaneously pushes the convex body 220 to the stopper 112 in the X-axis direction, so as to extend the convex body 220 in the Y-axis direction.

[0060] In the above-mentioned extension jig 100, when the side pusher 120 slides along the guide groove 111b, it can simultaneously push the protrusion 220 to the limit member 112 along the X-axis direction. The protrusion 220 is extended along the Y-axis direction under the interaction of the side pusher 120 and the limit member 112, thereby achieving the required size requirements of the protrusion 220. The structure is simple, the operation is convenient, and the cost of the protrusion 220 in the extended workpiece 200 is reduced.

[0061] In this embodiment, there are two protrusions 220 on the workpiece 200, and correspondingly, there are two guide grooves 111b and two side pushers 120. After the workpiece 200 is placed on the bearing surface 111a, the two protrusions 220 are respectively located on both sides of the limiter 112 in the X-axis direction, and the two guide grooves 111b are symmetrically arranged with the limiter 112 as the center. It should be noted that the number of side pushers 120 can be determined according to the number of protrusions 220 to be processed on the workpiece 200, and is not specifically limited here. Please refer to Figure 3In some embodiments, the guide groove 111b includes a guide groove 111c and a limit groove 111d sequentially arranged along the Y-axis direction. The guide groove 111c is inclined relative to the bearing surface 111a and connected to the limit groove 111d. The limit groove 111d is extended along the Z-axis direction on a side close to the limit member 112. The side thrust member 120 includes a sliding body 121 and a supporting body 122. The sliding body 121 is slidably arranged in the guide groove 111c. The supporting body 122 is connected to the sliding body 121 and is slidably arranged in the limit groove 111d. The plane of the side of the supporting body 122 facing the limit member 112 is perpendicular to the bearing surface 111a, and the supporting body 122 pushes the protrusion 220 along the X-axis direction toward the side of the limit member 112.

[0062] Therefore, the guiding groove 111 c can guide the sliding body 121 to slide, and the limiting groove 111 d can limit the abutting body 122 in the X-axis direction, which is beneficial to improve the accuracy of the abutting body 122 abutting the protrusion 220 .

[0063] In this embodiment, the guiding groove 111c penetrates two side surfaces of the carrier 111 in the Z-axis direction and one side surface in the Y-axis direction along its inclined direction, and the limiting groove 111d penetrates two side surfaces of the carrier 111 in the Z-axis direction.

[0064] In this embodiment, the sliding body 121 and the abutting body 122 are an integrated structure, which is beneficial to simplifying the processing technology of the side thrust member 120 , thereby reducing the manufacturing cost of the side thrust member 120 .

[0065] See also Figure 3 and Figure 4 In some embodiments, the angle between the side wall 111e of the guide groove 111c and the bearing surface 111a is α, and α satisfies the relationship: 60°≤α≤75°, for example, α is 60°, 65°, 70°, 75°, 30°. In this embodiment, α is 75°.

[0066] Therefore, by properly configuring the size of α, the moving distance of the sliding body 121 on the X-axis can be ensured on the basis of forming a good guiding effect on the sliding body 121. Specifically, if α is less than 60°, the inclination angle of the side wall 111e of the guide groove 111c relative to the bearing surface 111a is too large, and the sliding body 121 is easily stuck during the process of guiding the sliding body 121. If α is greater than 75°, the sliding body 121 moves the same distance in the Z-axis direction, and the distance moved on the X-axis is too small.

[0067] See also Figure 3 In some embodiments, the end corner of the supporting body 122 away from the sliding body 121 is an arc-shaped structure, which can reduce the damage to the convex body 220 caused by the supporting body 122 in the process of abutting the convex body 220.

[0068] See also Figure 3 In some embodiments, the extension jig 100 further includes an elastic member 130. The elastic member 130 is disposed between the sliding body 121 and the side wall 111e of the guide groove 111c, and two ends of the elastic member 130 respectively abut against the sliding body 121 and the side wall 111e of the guide groove 111c.

[0069] During operation, a force is applied downward along the Z-axis direction to the sliding body 121, and the sliding body 121 moves in the guide groove 111c and compresses the elastic member 130. After the convex body 220 is pushed into shape by the supporting body 122, the force applied to the sliding body 121 is withdrawn, and the elastic force of the compressed elastic member 130 is released, and then the sliding body 121 is elastically pushed to move upward along the Z-axis direction in the guide groove 111c to achieve reset.

[0070] See also Figure 3 and Figure 4 In some embodiments, a side push groove 121a is formed on one side of the sliding body 121 facing the limit member 112, and a receiving groove 111f is formed on the side wall 111e of the guide groove 111c close to the limit member 112. Both ends of the elastic member 130 are respectively received in the side push groove 121a and the receiving groove 111f. The side push groove 121a is parallel to the extension direction of the receiving groove 111f and intersects with the extension direction of the guide groove 111c.

[0071] Therefore, the radial extension of the elastic member 130 can be reduced by the side-pushing groove 121 a and the receiving groove 111 f , thereby improving the stability of the elastic force of the elastic member 130 .

[0072] It should be noted that in other embodiments, extension bodies may be respectively provided on a surface of the sliding body 121 facing the stopper 112 and on the side wall 111e of the guiding groove 111c close to the stopper 112, so that the two ends of the elastic member 130 respectively abut against the two extension bodies.

[0073] See also Figure 4 In some embodiments, the distance between the bottom wall 111g of the receiving groove 111f and the side wall 111e of the guiding groove 111c in the X-axis direction gradually increases in the direction away from the bearing surface 111a, and the angle between the bottom wall 111g of the receiving groove 111f and the side wall 111e of the guiding groove 111c is β, and β satisfies the relationship: 5°≤β≤15°, for example, β is 5°, 10°, and 15°. In this embodiment, β is 10°.

[0074] Therefore, by properly configuring the size of β, the swing of the elastic member 130 in the radial direction can be reduced while the elastic member 130 generates sufficient elastic force on the sliding body 121. Specifically, if β is less than 5°, the receiving groove 111f cannot completely receive the end of the elastic member 130, and the elastic member 130 is prone to swing in the radial direction. If β is greater than 15°, the elastic member 130 cannot generate sufficient elastic force on the sliding body 121 in the sliding direction of the sliding body 121.

[0075] See also Figure 2 and Figure 3 In some embodiments, the bearing seat 110 further includes a stopper 113 . The stopper 113 is disposed on the bearing surface 111 a , and the stopper 113 is provided with a stopper groove 113 a connected to the guide groove 111 b , and the stopper groove 113 a is used to receive the workpiece 200 .

[0076] Therefore, the stopper 113 can prevent the workpiece 200 from moving relative to the supporting member 111 during the pushing process of the protrusion 220 , thereby improving the stability of the extending protrusion 220 .

[0077] The embodiment of the utility model further provides an extension mold 1000, which is used to extend the convex body 220 on the main body 210, and includes an upper pressing fixture 300 and the extension fixture 100 of the above embodiment. The upper pressing fixture 300 includes an upper pressing seat 310 and a lower pressing member 320, the upper pressing seat 310 is adapted to the bearing seat 110, the lower pressing member 320 is connected to one side of the upper pressing seat 310 and corresponds to the side push member 120, and the lower pressing member 320 is used to press the side push member 120 along the Z-axis direction, so that the side push member 120 slides along the guide groove 111b, and the upper pressing seat 310 presses the workpiece 200 along the Z-axis direction.

[0078] In this embodiment, there are two pressing members 320 , which are spaced apart along the X-axis direction and correspond one to one to the two side pushing members 120 .

[0079] See also Figure 5When the above-mentioned extension mold 1000 extends the protrusion 220, the workpiece 200 is first placed on the bearing surface 110a and received in the stop groove 113a, so that the protrusion 220 is located between the limit member 112 and the side push member 120, and then, the extension fixture 100 is driven to move downward along the Z axis, so that the lower pressing member 320 pushes the side push member 120 to slide along the guide groove 111b. During this process, the supporting body 122 of the side push member 120 pushes the protrusion 220 to the limit member 112 along the X-axis direction, the upper pressing seat 310 presses the protrusion 220 along the Z-axis direction, and the sliding body 121 compresses the elastic member 130 until the protrusion 220 reaches the preset size requirement. After the protrusion 220 is extended to the preset size requirement, it drives the upper pressing fixture 300 to separate from the extending fixture 100. At this time, the elastic force of the compressed elastic member 130 is released, thereby elastically pushing the side push member 120 to slide along the guide groove 111b to reset.

[0080] Therefore, in the above-mentioned extension mold 1000, when the side push member 120 slides along the guide groove 111b, it can simultaneously push the protrusion 220 to the limit member 112 along the X-axis direction. The protrusion 220 is extended along the Y-axis direction under the joint action of the side push member 120, the limit member 112 and the upper pressure seat 310, thereby achieving the required size requirements of the protrusion 220. The structure is simple, the operation is convenient, and the cost of extending the protrusion 220 is reduced.

[0081] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
