Description

Technical Field

[0001] The utility model relates to the technical field of precision connector preparation, in particular to a heading machine for pipe drawing processing. Background Art

[0002] Tube drawing is a method of changing the cross-sectional shape and size of the tube by clamping one end of the tube and then pulling it in a mold. It is a more suitable preparation method for the flat round tube used for the type-c interface.

[0003] During the drawing process, one end of the tube needs to be clamped by the chuck of the drawing machine. When the tube is clamped for the first time, its end is simply shaped. After the first clamping, the end will be a flat sheet structure with a width larger than the width of the tube. In the subsequent perforation process of multiple drawing processes, the flat sheet structure cannot pass through the mold smoothly. It is necessary to manually reshape the flat sheet structure again to reduce the width so that it can pass through the mold smoothly.

[0004] During the shaping process, the pipe is usually squeezed and deformed by using pliers or hammers. Since the flat sheet structure is difficult to deform during the knocking process, it needs repeated adjustments, which affects the shaping efficiency and is prone to damage, resulting in the scrapping of the pipe.

[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 Figures 1 to 3 As shown, an embodiment of a heading machine for pipe drawing processing of the utility model comprises a shaping die and a pressing mechanism 2, the shaping die is arranged in the pressing mechanism, the shaping die comprises a lower die bottom plate 3 and an upper die bottom plate 4, an X-axial movable slide groove 5 is arranged on the lower die bottom plate, two L-shaped positioning side plates 6 are arranged in the X-axial movable slide groove, the two L-shaped positioning side plates abut to form a Y-axial concave shaping space 7, a shaping header 8 is arranged at the bottom of the upper die bottom plate, and the shaping header is provided with extrusion plates 9 on both sides of the upper die bottom plate on the X-axial direction, the two extrusion plates and the shaping header move along the Z-axis direction, the two extrusion plates are used to extrude the two L-shaped positioning side plates to move close to each other in the moving slide groove, and the shaping header extends into the Y-axial concave shaping space for cooperation in shaping.

[0025] The downward pressing mechanism drives the lower mold bottom plate of the shaping mold to move downward, that is, the shaping head extends into the Y-axis concave shaping space. During this whole process, the two extrusion plates will collide with the outer edges of the corresponding L-shaped positioning side plates and exert extrusion force, so that the two L-shaped positioning side plates move closer to each other, so that the width space dimension of the Y-axis concave shaping space in the X-axis direction is reduced, and the shaping head moves downward, so that the height space dimension of the Y-axis concave shaping space in the Z-axis direction is reduced, and finally the shaping space is obtained.

[0026] The flattened end of the pipe is deformed by the shaping head and the two L-shaped positioning side plates in the shaping space, so as to obtain a size that can pass through the drawing die. After the shaping is completed, the shaping head is reset, and the two extrusion plates are reset accordingly, and the extrusion of the two L-shaped positioning side plates is released, so that the shaped pipe can be taken out from between the two L-shaped positioning side plates.

[0027] In order to improve the smoothness of the shaping process, a spring 10 is arranged between the two L-shaped positioning side plates. When the two L-shaped positioning side plates move closer to each other, the spring is compressed and stores force. When the shaping is completed, the spring resets to push the two L-shaped positioning side plates out and move them away, so that the pipe can be taken out smoothly without manually separating the two L-shaped positioning side plates.

[0028] The L-shaped positioning side plate can slide in the X-axial moving slot, mainly a sliding limit plate 11 is arranged at the bottom of the L-shaped positioning side plate, the sliding limit plate is arranged in the X-axial moving slot, and two anti-slip limit columns 12 are also arranged in the X-axial moving slot. The two L-shaped positioning side plates are arranged between the two anti-slip limit columns to limit the sliding limit plate from slipping out of the X-axial moving slot, that is, to limit the moving position of the L-shaped positioning side plate, thereby ensuring that the relative position of the extrusion plate and the L-shaped positioning side plate is accurate when the extrusion plate is pressed down.

[0029] The extrusion plate moves along the Z-axis direction. In order to ensure its extrusion effect, a first inclined surface 13 is provided on the outer surface of the L-shaped positioning side plate, and a second inclined surface 14 is provided on the inner surface of the extrusion plate. Specifically, the extrusion plate first contacts the first inclined surface, and the first inclined surface obliquely transfers the force in the Z-axis direction, thereby obtaining the moving power of the L-shaped positioning side plate in the X-axis direction; the second inclined surface utilizes the internal space to improve the connection strength of the extrusion plate.

[0030] Since the end of the pipe has been clamped and flattened before shaping, in order to improve the shaping effect, a deformation groove 131 is set at the inner angle of the Y-axial concave shaping space. When the two L-shaped positioning side plates are approaching each other, the clamped end will bend in the deformation groove. Combined with the shaping head, it can ensure that damage to the pipe is reduced during shaping, and both sides of the pipe can achieve effective bending and contraction in the deformation groove to reduce the width direction size.

[0031] The above-mentioned pressing mechanism includes a lower platform 141 and an upper platform 15, a guide column 16 is arranged between the lower platform and the upper platform, a pressing cylinder 17 is arranged on the upper platform, the pressing cylinder is connected to the pressing platform 18, the pressing platform is arranged on the guide column between the lower platform and the upper platform, the lower mold bottom plate is fixed on the lower platform, the upper mold bottom plate is fixed on the pressing platform, the pressing cylinder provides pressing power, and the pressing platform moves along the direction of the guide column.

[0032] In one embodiment, a mounting frame is also provided on the side of the lower platform, and an upper limit sensor and a lower limit sensor for detecting the moving position of the pressing platform are provided on the mounting frame to ensure stable operation. The lower platforms on both sides of the Y-axis concave shaping space are respectively provided with a loading area and a detection area, and a detection sensor is provided in the detection area. When the pipe is placed on the two L-shaped positioning side plates, it can be detected by the detection sensor, and then the pressing mechanism is activated once, without manual operation, thereby improving the degree of automation.

[0033] 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.
