Description

Technical Field

[0001] The utility model relates to the technical field of high-precision connectors, in particular to a fixing device for batch wire cutting of oblate round tubes. Background Art

[0002] Type-C is a form of USB interface and a hardware interface specification of a universal serial bus. It has been widely promoted and used because it supports positive and negative symmetric plugging and unplugging and supports higher power transmission.

[0003] The plug-in end of the Type-C interface is protected by a flat round stainless steel metal tube. The flat round stainless steel metal tube is formed by multiple drawing of a long straight round tube to form a long straight flat round tube, which is then cut into a short flat round tube.

[0004] In the process of cutting long straight flat round tubes to form short-sized flat round tubes, wire cutting is used to process the long straight flat round tubes. The end face after wire cutting is flat, which meets the subsequent processing requirements. In order to improve the efficiency, the long straight flat round tubes are stacked before cutting. The commonly used method is to wrap multiple long straight flat round tubes with heat shrinkable plastic tubes, and then blow hot air to make the heat shrinkable plastic tubes tightly wrap the multiple long straight flat round tubes to achieve positioning and batch processing. However, this method cannot be used for large-scale cutting. The processing capacity at one time is only about 10 tubes, which cannot meet the requirements of large-scale and fast cutting.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] Reference Figure 1 and Figure 2 As shown, an embodiment of a fixing device for batch wire cutting of flat round tubes of the utility model comprises a concave base 1 and an upper cover 2 locked on the concave base, a first S-cutting channel 3 is arranged on the upper cover, the concave base comprises a bottom frame 4, a first parallel side plate 5 and a second side plate 6 are arranged on the bottom frame, a plurality of L-shaped support arms 7 are arranged on the side plates, a first gap 8 is provided between two adjacent L-shaped support arms, and a transverse rod end of one of the L-shaped support arms is fixedly connected to the bottom frame and a second gap 9 is provided between the vertical rod and the first side plate, a transverse rod end of the other L-shaped support arm is fixedly connected to the bottom frame and a third gap 10 is provided between the vertical rod and the second side plate, the first gap, the second gap and the third gap cooperate to form a second S-cutting channel, the first S-cutting channel and the second S-cutting channel overlap in the projection direction, the L-shaped support arm and the upper cover cooperate to form a placement space, the pipe is placed in the placement space, and then cut by the wire cutting equipment.

[0025] Specifically, in the process of tooling preparation, the upper cover can be obtained by wire cutting, first punching a hole at the starting position, and then cutting along the route of the first S-cutting channel to obtain an outer frame and multiple straight strips in the frame; the concave base can also be obtained by wire cutting, mainly for cutting the groove metal body with a bottom surface and two side edges (a first side panel and a second side panel). After cutting, the bottom surface is cut to be consistent with the structure of the upper cover, with an outer frame (i.e., the bottom frame) and multiple straight strips, and multiple grooves are cut on the side. The cut and separated parts in the grooves will be connected with the straight strips in the bottom frame to form an L-shaped support arm. Since the side panels and the bottom frame are integrated, the L-shaped support arm is connected to the bottom frame, and the side panels also provide better connection strength. The overall structure is simple to prepare and has good strength, which is convenient for supporting the placement of pipes and reducing vibration during cutting, thereby improving cutting quality.

[0026] In the concave base prepared by the above method, the inner sides of the L-shaped support arms are all planes, and the inner surface of the transverse rod of the L-shaped support arm is flush with the inner surface of the corresponding first side panel or the second side panel, which has a higher fit with the pipe. The short-sized flat round tube will not move and fall after cutting, so that no interference will occur, thereby ensuring the cutting effect.

[0027] During the cutting process, the pipes are stacked and placed in a concave base. Figure 3 As shown, the upper cover is then put on, which serves to fix and limit the stacked pipes to avoid problems such as shaking and movement during the cutting process. Then, one end of the cutting molybdenum wire of the wire cutting equipment is passed through and fixed, and then the equipment is started for cutting. The cutting route is the direction of the first S cutting channel. After the cutting is completed, the molybdenum wire is removed, and a large number of short-sized flat round tubes can be obtained by opening the upper cover.

[0028] Since the first S-cutting channel and the second S-cutting channel need to maintain overlap in the projection direction, positioning holes 11 are provided on the first side panel and the second side panel, and positioning columns are provided on the bottom of the upper cover corresponding to the positioning holes. The positioning columns cooperate with the alignment holes to determine the relative positions of the concave base and the upper cover, which is convenient to operate and ensures installation accuracy.

[0029] Since the upper cover is made of metal, in order to avoid excessive damage caused by hard contact between the upper cover and the pipe, a hard plastic pad can be provided at the bottom of the upper cover to reduce damage caused by friction and improve cutting quality.

[0030] Reference Figure 4 and Figure 5 As shown, the concave base is placed on the placement bracket 111 of the wire cutting machine and fixed by a pressure iron 12. Specifically, the pressure iron is sleeved on the screw 14 and is provided with a downward pressure nut 13. The bottom of the screw is connected to the placement bracket, which can be a threaded connection. A support plate 15 is also provided on the side of the screw away from the concave base. The bottom of the support plate abuts against the placement bracket, and the top abuts against the bottom of the pressure iron. The downward pressure nut provides downward pressure. One end of the pressure iron presses the upper surface of the side of the concave base, and the other end provides a reaction force through the support plate, thereby achieving a clamping effect. In order to ensure the stability of the support plate, a support plate 16 is provided on the support plate, and the support plate is sleeved on the screw to prevent the support plate from falling off due to force. This setting also does not require the support plate to be welded to the placement bracket, and the disassembly is convenient and reliable. After being fixed with the pressure iron, a avoidance port 17 for avoiding the pressure iron is provided on the upper cover to avoid interference.

[0031] The above embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in this technical field on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the claims.
