Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0038] Snake bone parts are parts used in snake bone structures. Snake bone structures are usually composed of multiple snake bone parts, which are connected to each other through a specific connection method to form a structure that can bend and rotate.

[0039] The specific shape and structure of the snake bone parts will vary according to their application and design requirements. Generally speaking, the snake bone parts have the following characteristics:

[0040] Connectivity: Snake bone parts usually have structures for connecting other parts, such as grooves, hinged ears or other connection methods to achieve assembly and flexibility of the snake bone structure.

[0041] Bendability: In order for the snake structure to bend and adapt to different shapes, the snake parts usually have a certain degree of bendability or elasticity.

[0042] Positioning and rotation functions: Some snake bone parts may contain positioning structures or rotation components to ensure the accuracy and stability of the snake bone structure during movement.

[0043] Material selection: Snake bone parts can be made of various materials, common ones include metal (such as stainless steel, titanium alloy, etc.) and plastic.

[0044] Snake bone parts have a wide range of applications in some fields, such as medical devices (such as endoscopes), robotics, mechanical transmission, etc. They can provide flexible movement and precise control, allowing devices to operate in complex environments.

[0045] The existing equipment for punching grooves of snake-bone parts is not convenient to use and has low production efficiency. The die for punching grooves of snake-bone parts provided by the present application is extended by a telescopic mechanism, driving two inclined top blocks to move horizontally, and the first inclined surface is slidably connected with the second inclined surface, so that the two convex films move inwards relative to each other to clamp the snake-bone parts. The snake-bone parts are squeezed and deformed by the left and right convex dies to form a groove. The die provided by the present application has a high degree of automation, is easy to use, and greatly improves production efficiency.

[0046] The specific structure of the die for stamping grooves of snake bone parts provided in the present application is described in detail below in conjunction with the accompanying drawings.

[0047] Reference Figure 1-Figure 9 As shown, the embodiment of the present application provides a die for punching grooves of snake bone parts, comprising a base plate 1 and a telescopic mechanism 2, a tilted top fixing block 3, a slide rail fixing seat 4 and a concave film core rod 5 arranged on the base plate 1;

[0048] like Figure 1 As shown, the telescopic mechanism 2 is arranged at the left end of the bottom plate 1, and the telescopic end of the telescopic mechanism 2 reciprocates in the horizontal direction. The inclined top fixing block 3 is a plate body arranged longitudinally. The inclined top fixing block 3 is fixedly arranged at the telescopic end of the telescopic mechanism 2, that is, the right end of the telescopic mechanism 2. Both ends of the inclined top fixing block 3 in the longitudinal direction are provided with inclined top blocks 6, that is, the front and rear ends of the right side surface of the inclined top fixing block 3 are provided with inclined top blocks 6, and the inclined top blocks 6 can be U-shaped plates. The inclined top blocks 6 extend to the right, and the opposite surfaces of the two inclined top blocks 6 away from the end of the telescopic mechanism 2 are provided with first inclined surfaces 601, and the first inclined surface 601 can be a 45° inclined surface. The end of the first inclined surface 601 away from the telescopic mechanism 2 is inclined outward, that is, the right end of the first inclined surface 601 is inclined outward;

[0049] The slide rail fixing seat 4 is arranged on the right side of the bottom plate 1, and the slide rail fixing seat 4 is arranged longitudinally. The front and rear sides of the slide rail fixing seat 4 are provided with sockets. Two U-shaped inclined top blocks 6 are respectively plugged into the two sockets. The right side of the slide rail fixing seat 4 is provided with a slide rail 7, and the slide rail 7 extends longitudinally. The two sliders of the slide rail 7 are provided with convex membranes 8. The main body of the convex membrane 8 is a longitudinal plate body. The outer ends of the two convex membranes 8 are provided with second inclined surfaces 801, and the second inclined surfaces 801 match the first inclined surfaces 601. The right end of the second inclined surface 801 is inclined outwardly. The inner ends of the two convex membranes 8 are provided with groove teeth 802, and the groove teeth 802 are outwardly protruding teeth. The specific shapes and spacings of the multiple groove teeth 802 are determined according to the groove design of the snake bone to be processed;

[0050] The concave film core rod 5 is vertically arranged on the right side of the base 1, and the concave film core rod 5 is located between the two convex films 8. The outer wall of the concave film core rod 5 is provided with a groove 501 corresponding to the groove teeth 802. The snake bone part is sleeved on the concave film core rod 5, and the two convex films 8 clamp the snake bone part to form a groove on the snake bone part. The tolerance is reasonably designed to ensure that there is a certain gap between the snake bone part after the groove and the concave film core rod 5 to avoid the snake bone part after the groove and the concave film core rod 5 being stuck;

[0051] During processing, the ungrooved snake-bone part is sleeved on the concave film core rod 5, and the telescopic mechanism 2 is extended, driving the inclined top fixing block 3 and the inclined top block 6 to move to the right. The first inclined surface 601 of the inclined top block 6 is slidably connected with the second inclined surface 801 of the convex film 8, pushing the two convex films 8 to move inward relative to each other, so that the two convex films 8 clamp the ungrooved snake-bone part. Under the action of the groove 501 of the concave film core rod 5 and the groove teeth 802 of the convex film 8, the ungrooved snake-bone part forms a pressed groove to obtain a finished snake-bone part.

[0052] Reference Figure 1 and Figure 5 As shown, in some embodiments, the mold further includes a rebound component 9, which is used to automatically separate the two convex films 8, so as to facilitate the snake bone part to be connected to the concave film core rod 5, or to be removed from the concave film core rod 5, thereby improving production efficiency;

[0053] The rebound component 9 is disposed on the slide rail fixing seat 4, and the rebound component 9 has two opposite telescopic ends, and the two telescopic ends of the rebound component 9 are respectively in contact with the opposite surfaces of the two sliders of the slide rail 7;

[0054] In the natural state, the rebound component 9 is in a balanced state, and the two convex membranes 8 have a certain distance between them. During processing, the two convex membranes 8 drive the two sliders to move inward relative to each other, so that the rebound component 9 is compressed and stores force. After processing, when the telescopic mechanism 2 shortens and resets, it drives the inclined top fixing block 3 and the inclined top block 6 to move to the left, and the inclined top block 6 is separated from the convex membrane 8. Under the action of the elastic force of the rebound component 9, the two sliders drive the two convex membranes 8 to move relative to each other, thereby separating the two convex membranes 8 from the snake bone parts.

[0055] In some embodiments, the rebound assembly 9 includes a rebound seat 901, which may be square or T-shaped. The rebound seat 901 is fixed to the middle of the upper surface of the slide rail fixing seat 4. The rebound seat 901 is provided with a rebound hole 902. The axis of the rebound hole 902 is parallel to the extension direction of the slide rail 7. A spring 903 is provided in the rebound hole 902. The outer end of the spring 903 extends out of the rebound hole 902, and the outer end of the spring 903 abuts against the outer wall of the slider.

[0056] During processing, the two convex membranes 8 clamp the snake bone part, and the spring 903 is squeezed and compressed by the two sliders. After processing, the telescopic mechanism 2 is reset, and the spring 903 pushes the two sliders to move outward, and the two convex membranes 8 are separated from the snake bone part, thereby facilitating the connection of the snake bone part to the concave membrane core rod 5, or removing it from the concave membrane core rod 5, thereby improving production efficiency.

[0057] Reference Figure 5 As shown, in some embodiments, the mold further includes a limiting component 10;

[0059] The telescopic mechanism 2 and the slide rail fixing seat 4 are fixedly arranged, and the moving end of the limit assembly 10 is adjustable. The moving end of the limit assembly 10 abuts against the slide rail fixing seat 4 to limit the maximum distance between the inclined top fixing block 3 and the telescopic mechanism 2, that is, to limit the extendable length of the telescopic mechanism 2, and limit the rightward movement position of the inclined top fixing block 3 and the inclined top block 6. The rightward movement of the inclined top block 6 drives the convex membrane 8 to move inward, thereby limiting the minimum distance between the two convex membranes 8, thereby avoiding excessive clamping of the snake bone parts by the two convex membranes 8.

[0060] In some embodiments, the inclined top fixing block 3 is provided with a limiting screw hole;

[0061] The limiting assembly 10 includes a limiting screw 1001, the limiting screw 1001 is screwed to the limiting screw hole, and the end of the limiting screw 1001 abuts against the slide rail fixing seat 4;

The insertion rod 503 is fixed at the bottom end of the rod body 502. The insertion rod 503 is inserted into the insertion hole 1102, so that the concave film core rod 5 is vertically fixed.

[0066] In some embodiments, the two convex films 8 are respectively located on both sides of the concave film core rod 5, clamping the snake bone parts sleeved on the concave film core rod 5, therefore, the front and rear sides of the concave film core rod 5 are provided with grooves 501 to cooperate with the two convex films 8 on the front and rear sides, in order to make the grooves 501 on both sides face the front and rear respectively, it is necessary to limit the direction and angle of the concave film core rod 5, therefore, the side wall of the insertion rod 503 is provided with a limiting groove 504, the limiting groove 504 can be a square slide groove, the upper surface of the connecting block 1101 is provided with a limiting block 1103, the limiting block 1103 can be a square clamping strip, and the limiting block 1103 is clamped with the limiting groove 504;

[0067] When the concave film core rod 5 is inserted into the core rod fixing assembly 11, the limiting block 1103 is inserted into the limiting groove 504, so that the grooves 501 on both sides of the concave film core rod 5 face forward and backward respectively, and cooperate with the two convex films 8 on the front and rear sides.
