Description

Technical Field

[0001] The utility model relates to the technical field of measuring tooling, in particular to a measuring tooling for a welded pipe die. Background Art

[0002] After being used for a long time, the extrusion die may be deformed and its cross-section is no longer a complete circle. If the welded pipe body continues to be processed, the processing accuracy will be reduced. Therefore, it is necessary to measure the extrusion die to timely detect the deformed extrusion die. For example, a measuring tooling for the radian of a roller-type welded pipe die recorded in the publication number CN211012790U includes a measuring plate corresponding to the roller-type die. An upward extending upper positioning part is arranged on the upper side of the measuring plate, and a downward extending lower positioning part is arranged on the lower side of the measuring plate. An upper positioning arc edge, an intermediate connecting edge and a lower positioning arc edge are arranged on the right side of the measuring plate. The upper positioning arc edge is arranged corresponding to the upper positioning part, and the lower positioning arc edge is arranged corresponding to the lower positioning part. The intermediate connecting edge is arranged vertically; the roller-type die includes an upper cylindrical part, an upper diameter-changing part, an intermediate connecting part, a lower diameter-changing part and a lower cylindrical part. The upper positioning part is arranged in contact with the side surface of the upper cylindrical part, the upper positioning arc edge is arranged in contact with the side surface of the upper diameter-changing part, the lower positioning part is arranged in contact with the side surface of the lower cylindrical part, and the lower positioning arc edge is arranged in contact with the side surface of the lower diameter-changing part;

[0003] The above device can inspect and measure two arc angles on the side surface of the roller-type die. However, it is not convenient to lubricate the extrusion die during detection, and it cannot reduce the friction between the extrusion die and the welded pipe body and between the detection component and the extrusion die, and cannot reduce the wear among the three.

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a measuring tooling for a welded pipe mold includes a measuring tooling main body 3 installed on both side surfaces of the mold main body 1. It is characterized in that the measuring tooling main body 3 includes a mounting seat 4, an adjusting seat 5, a slide seat 6, a mounting cylinder 7 and an extrusion rod 8. The upper surface of the mounting seat 4 is fixedly connected to the adjusting seat 5. The upper surface of the adjusting seat 5 is fixedly connected to the reducer 501. The inner surface of the adjusting seat 5 is rotatably connected to a lead screw 503. The outer surface of the lead screw 503 is threadedly connected to a slide seat 6. One side surface of the slide seat 6 is embedded and connected with a mounting cylinder 7. The inside of the mounting cylinder 7 is embedded and slidably connected with an extrusion rod 8. The upper surface of the extrusion rod 8 is fixedly connected to an oil storage tank 9.

[0023] Specifically, when in use, the extrusion mold 101 is rotatably installed inside the mold main body 1, and the extrusion mold 101 is in contact with the welded pipe main body 2. When measuring the curved surface of the extrusion mold 101, the shape of the extrusion mold 101 is a combination of two cones, and the horizontal cross-section is circular. After the extrusion mold 101 is deformed, the cross-section changes, and the acting force applied to the extrusion rod 8 changes. The extrusion mold 101 rotates to apply an acting force to the extrusion rod 8, and the distance sensor 602 measures the distance between the extrusion rod 8 and the distance sensor 602. When the extrusion rod 8 contacts the position where the curved surface radian is inconsistent, the distance between the distance sensor 602 and the extrusion rod 8 changes, thereby completing the measurement of the extrusion mold 101.

[0024] Embodiment 1

[0025] like Figures 1 - 4 As shown, the upper surface of the mounting seat 4 is fixedly connected to a limit rod 401, the slide seat 6 is nested in the outer surface of the limit rod 401, and the slide seat 6 and the limit rod 401 are slidably connected, the upper surface of the reduction box 501 is fixedly connected to a stepper motor 502, the output end of the stepper motor 502 and the input end of the reduction box 501 are fixedly connected, and the output end of the reduction box 501 and the lead screw 503 are fixedly connected.

[0026] In this embodiment, the limit rod 401 limits the rise or fall of the slide 6, starts the stepper motor 502, and the stepper motor 502 cooperates with the reduction box 501 to drive the screw rod 503 to rotate. Under the push of the thread, the slide 6 can rise and the slide 6 can fall when the stepper motor 502 reverses.

[0027] like Figures 1 - 4 As shown, a measuring frame 601 is fixedly connected to the outer surface of the slide 6, a distance sensor 602 is embedded in the outer surface of the measuring frame 601, a controller 603 is fixedly connected to the outer surface of the mold body 1, and the controller 603 and the distance sensor 602 are electrically connected.

[0028] In this embodiment, the distance sensor 602 and the controller 603 are connected by a spiral wire in the prior art. When the distance between the controller 603 and the distance sensor 602 changes, the spiral wire can still ensure the stability of the electrical connection.

[0029] Embodiment 2

[0030] On the basis of the first embodiment, in order to make up for the problem that it is inconvenient to lubricate the extrusion die 101 in the first embodiment.

[0032] In this embodiment, the spring 803 is always in a compressed state. The spring 803 cooperates with the resistance part 701 to squeeze the resistance ring 802, so that the extrusion rod 8 is always in contact with the extrusion mold 101, so that after the slide 6 rises or falls, the extrusion rod 8 can also be suitable for extrusion molds 101 of different sizes.

[0033] like Figures 1 - 4As shown in the figure, the upper surface of the oil storage tank 9 is threadedly connected with a cover body 901. The lower surface of the cover body 901 is provided with a threaded portion 902. The upper surface of the cover body 901 is fixedly connected with a rubber plate 903.
