Embodiment 1

[0049] The production process of the sounding gauge includes,

[0050] S1: material selection, the selection of circular steel as raw material cross-section;

[0051] S2: Calendering deformation, using a number of rolling mills 2 to carry out rolling deformation treatment on round steel. The rolling mill 2 is composed of at least two pressing rollers. A certain gap is left between the two pressing rollers, and rolling grooves are opened on the pressing rollers. The rolling grooves between the pressing rollers form the deformation channel 23 for the raw material to pass through. The raw material passes through several deformation channels 23, and the cross-section of the raw material gradually becomes trapezoidal, and continues to pass through the rolling mill 2 with different deformation channels 23, and the hypotenuse corresponding to the trapezoidal cross-section Gradually roll out the drop gap 14 on the top, so as to obtain the first product with a cross-sectional shape sim...

Embodiment 2

[0064] A rolling mill used for the calendering deformation step in the production of sounding gauges, comprising an upper pressing roll 21 and a lower pressing roll 22, the upper pressing roll 21 and the lower pressing roll 22 are facing each other and there is a gap between the remaining material 112, the upper pressing roll 21 and the lower pressing roll 22 The surface of the lower pressing roller 22 is provided with different processing grooves according to the different processing steps, and the processing grooves form a deformation channel 23 for raw materials to pass between the upper pressing roller 21 and the lower pressing roller 22 .

[0065] Wherein, the upper pressure roller 21 protrudes with a shunt pressure angle 211, and the lower pressure roller 22 is provided with a lower forming angle 221 matching the shunt pressure angle 211. A forming gap 231 and a deformation channel 23 are left between the forming angles 221, the forming gap 231 corresponds to the second b...

Abstract

The invention discloses a manufacturing technique of a depth scale and a rolling mill for the manufacturing technique and relates to the technical field of profiled material manufacturing technique. The manufacturing technique of the depth scale comprises the following steps: S1, material selection, selecting rolled steel with a round cross section as a raw material; S2, calendering deformation, comprising primary deformation and distributary; S3, rough machining, cutting excessive scraps formed by calendering on a primary product; S4, heat treatment, increasing the mechanical intensity of thematerial; S5, finish machining, polishing the surface of the primary product; S6, antirust treatment; and S7, packaging. A probing rod is integrally processed through a calendering deformation mannerto obtain the integrally molded penetration rod, so that the dimensional accuracy and mechanical intensity of the probing rod are higher.

Description

technical field [0001] The invention relates to the technical field of profile processing technology, in particular to a production technology of a sounding gauge and a rolling mill used in the technology. Background technique [0002] The depth gauge is a commonly used measuring tool, and the depth gauge is usually equipped with a probe rod, which is used to insert into the part where the depth is to be measured. [0003] Such as figure 1 Shown is the structure of the probe rod 1 on the existing sounding gauge, including the first base rod 11 and the second base rod 12, the two are connected together by welding, so that the first base rod 11 and the second base rod 12 A weld 13 is formed between them. [0004] Due to the height difference between the first base bar 11 and the second base bar 12 , a drop gap 14 is formed. The probe rod 1 is slidingly connected to the main body of the sounding gauge through the drop gap 14 . [0005] Since the first base rod 11 and the se...
