The utility model has the advantages that: the utility model provides a pair of be exclusively used in production welded tube roll cold type mould, simple structure can shorten the production cycle of welded tube roll, and energy saving and raw and other materials improve the production efficiency of whole welded tube roll, the extensive popularization and use of being convenient for.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present application, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

Fig. 1 is a first schematic structural diagram of the present invention;

fig. 2 is a schematic structural diagram of the present invention.

The reference numbers in the drawings are: 1. the sand-hanging device comprises an upper concave-convex type membrane, 2 a lower concave-convex type membrane, 3 lug climbers, 4 bolt grooves, 5 ball core sand columns, 6 hanging columns, 7 fastening bolts, 8 and a sand-hanging layer.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to further explain the present invention in detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and fig. 2, the cold-type die for producing the welded pipe roller is provided with an upper concave-convex film 1 and a lower concave-convex film 2 which are semicircular in section and are spliced up and down; a plurality of ear pieces 3 are arranged on the outer wall of the upper concave-convex membrane 1 and the outer wall of the lower concave-convex membrane 2 along the length direction; the lug 3 is provided with a bolt groove 4; the middle part in the cavity formed by combining the upper concave-convex membrane 1 and the lower concave-convex membrane 2 is also vertically penetrated with a ball core sand column 5 with adjustable diameter.

Wherein, the outer wall of the upper concave-convex membrane 1 and the outer wall of the lower concave-convex membrane 2 are also vertically provided with hanging columns 6 along the length direction. The suspension post 6 is connected with a fastening bolt 7 in a threaded manner. The inner wall of the upper concave-convex type membrane 1 is coated with a sand coating layer 8. The lower embossing film 2 is also coated with a sand-catching layer 8. The upper concave-convex type film 1 and the lower concave-convex type film 2 are both cast by HT 20-40 grade materials.

The use principle of the cold type die special for producing the welded pipe roller is as follows:

firstly, an operator needs to design a ball core sand column 5 with a middle part penetrating; after penetrating the bolt, closing an upper concave-convex membrane 1 and a lower concave-convex membrane 2, sleeving 1-2 steel plate filling rings with the thickness of 3-5 mm at the root of the bolt, then inserting the bolt into a bolt groove 4, sleeving 1-2 adjusting contraction birch strips with the thickness of 5mm at the head of the bolt, and then sleeving a nut for fastening; the upper concave-convex film 1 and the lower concave-convex film 2 are combined and then are arranged on a bottom box, and a ball core sand column 5 of an inner hole of a roll collar is arranged in the middle of the bottom box; the upper concave-convex type film 1 and the lower concave-convex type film 2 are both cast by using HT 20-40 grade materials; tempering at 450-650 ℃ by heat treatment before processing to eliminate the casting stress of the upper concave-convex film 1 and the lower concave-convex film 2; the upper concave-convex film 1 and the lower concave-convex film 2 can be used for 1-50 times; and hanging 12.5mm of sand in the cavity when the upper concave-convex film 1 and the lower concave-convex film 2 are molded, brushing 2-3 mm of zircon powder coating, sleeving the zircon powder coating at the position of the bottom box, drying in the shade for 2-3 days, and baking in a kiln for use.
