Abstract

The utility model relates to a tool for detecting the flatness of a die working belt, which is characterized by comprising a detection part and a handheld part which are combined with each other in an L shape; and the detection part is contacted with the die working belt so as to measure the flatness of the die working belt. The contact surface between the detection part and the die working belt is a smooth plane.

Description

The flatness testing tool of die working length

Technical field

The utility model relates to a kind of testing tool, is specifically related to a kind of testing tool that the die working length flatness is detected of when repairing a die, being used for.

Background technology

In the aluminium extrusion industry, the flatness of extrusion die work zone plays a key effect for the homogeneity control of the extrudate rate of outflow and the moulding of section bar.

In the prior art, judge the flatness of die working length, whether smooth through personnel's visualization surface that repairs a die usually, come the mould place under repair through visualization mold work belt surface again.Therefore to a great extent with of the judgement of individual's sensation, lack the auxiliary data that reach of quantifiable instrument and embody the auxiliary work zone leveling repair work of carrying out in the flatness of carrying out die working length.

The utility model content

The purpose of the utility model is to solve the defective that exists in the above-mentioned prior art, and a kind of mold formation degree testing tool is provided, can be through quantizing to embody the auxiliary work zone leveling repair work of carrying out.

The technical scheme of the utility model is following: a kind of flatness testing tool of die working length; Comprise and be a test section and the Handheld Division that the L type combines; Test section contacts with die working length to measure its flatness, and the contacted surface of this test section and die working length is a smooth horizontal plane.

Preferable, the angle between test section and the Handheld Division is 89.8-90.2 °, and is better, the angle between test section and the Handheld Division is 90 °, 89.8 °, 89.9 °, 90.1 ° or 90.2 °.

Preferable, the length of test section is 30-60mm.

In the possibility of the utility model, also can have sensor on the smooth horizontal plane of test section, this sensor is pressure transducer or laser sensor.

The beneficial effect of the utility model is:

Testing tool (one group of special-purpose inspection cubing that angle is different, length is different) through special use; Come the work zone flatness repaired the data support is provided; Data embody to make the mould repairman can pass through intuitively; Come the flatness of judgment task band, more effectively reach the purpose that reaches the whole surfacing repairing in work zone accurately.

Fig. 2 is the utility model mould synoptic diagram;

Fig. 3 A-3C is for using operation chart, and wherein Fig. 3 A is the situation synoptic diagram that testing tool begins to detect; Fig. 3 B is the irregular situation synoptic diagram in work zone; Fig. 3 C is the smooth situation synoptic diagram in work zone.

Embodiment

Come further to set forth the utility model through embodiment below.

As shown in Figure 1, be the mold formation degree testing tool 1 of the utility model, its xsect is the L type, comprises a test section 11 and a Handheld Division 12.In conjunction with the angle of the same empty cutter vertical profile of die working length generally in 89.8-90.2 ° scope; Normally 90 °, or short stream angle (89.8,89.9 etc.), or hinder angle (90.1,90.2 etc.)); Therefore the angle correspondence between test section 11 and the Handheld Division 12 is in 89.8-90.2 ° of scope, preferred 90 °, 89.8 °, 89.9 °, 90.1 ° or 90.2 °.The length of test section 11 generally depends on the work zone surface size, generally between 30-60mm.

As shown in Figure 2, be work zone to be detected 2 synoptic diagram.During operation, shown in Fig. 3 A, according to the testing tool 1 of work zone angle Selection corresponding angle.After red lead powder and kerosene mixed, spread upon the bottom surface of test section 11, and then Handheld Division 12 is close to the vertical profile of work zone, contact work zone 2 with the bottom surface of test section 11, an end horizontal translation of 2 is to the other end from the work zone.Shown in Fig. 3 B-3C; After smearing red lead powder and kerosene mixture, have one deck on the surface, work zone and smear vestige 3, if smear the local uncoated coating that vestige 3 occurs shown in Fig. 3 B; Explain that then this work zone must carry out leveling work; Carry out so repeatedly, up to work zone surface smear vestige 3 can complete coating pigment shown in Fig. 3 C till, explain that the surface, work zone is smooth fully this moment.

In addition, in the preferred version of the utility model, can also sensor be set at four edges of bottom surface of test section 11, the upper surface of test section 11 has display device, is connected with sensor, can show the information of sensor feedback.This sensor can be laser sensor or pressure transducer; When using, when with testing tool 1 from one section horizontal translation of work zone to the other end, when having detected the tool surfaces out-of-flatness; Display device can show out-of-flatness; Explain that then this work zone must carry out leveling work, carry out so repeatedly, up to display device show smooth fully till.
