Description

Oval " manhole ring " processing tool

Technical field

The present invention relates to instrument equipment technology field, specifically a kind of ellipse " manhole ring " processing tool.

Background technology

Oval " manhole ring " is industrial equipment parts commonly used, and particularly, on boiler, frequency of utilization is higher, and a boiler will be used several ellipses " manhole ring " sometimes.And the preparation method of oval " manhole ring " is mainly to suppress with forcing press.When making oval " manhole ring ", because the pressure-bearing surface up and down of forcing press is all planes, during compacting, the circumference of steel ring is stressed irregular, the ellipse short shaft two ends that formed " manhole ring " that process have one section to be plane, elliptical shape is lack of standardization, and ellipse " manhole ring " standard in order to make to suppress, have to manually arrange for the second time, both time-consuming taking a lot of work, efficiency is not high again.Some factories are in order to remove the artificial operation arranged for the second time from, increased pressure head on forcing press, this measure can reach set processing purpose, but the model difference due to forcing press, the stroke of its forcing press is also different, need to carry out necessary adjustment to forcing press, thereby increase material usage, cause manufacturing cost to raise.The factory also had is for ellipse " manhole ring " profile that makes to suppress standard more, directly upper push-down head is made to ellipse, this measure has produced again another problem, variation has occurred in the size of oval " manhole ring ", upper push-down head also needs to change thereupon, this just needs to prepare several pressure heads, thereby has strengthened processing cost.Simultaneously, the confidential power consumption of working pressure and acquisition cost are also high.

Summary of the invention

The technical problem to be solved in the present invention is: make a kind of ellipse " manhole ring " processing tool, the upper and lower pressure head of this frock is contained on the T shape column of both sides, push-down head can move up and down along the T shape column of both sides under the effect on oil top, and circular steel ring is pressed into to ellipse " manhole ring ", can also do corresponding the adjustment to oval major axis and minor axis as required simultaneously.

Realize that the technical scheme that above-mentioned target is taked is: oval " manhole ring " processing tool comprises T shape column, seaming chuck, push-down head, base plate, You Ding, two T shape columns are weldingly fixed on two of base plate, seaming chuck is weldingly fixed on the top of T shape column, push-down head is installed on the middle part of T shape column and can moves up and down along T shape column by draw-in groove, the bottom on oil top is packed in the middle part of base plate, and upper end connects the push-down head flat board on push-down head.The pointer that laterally is connected on the draw-in groove of a side, the supporting rule that is connected on the fourth plate with draw-in groove homonymy T shape column.

Two of raising-plate in described seaming chuck is weldingly fixed on the T shape column on both sides and is mutually vertical with T shape column; Seaming chuck reinforcement two ends are weldingly fixed on the riser of T shape column, and upper end is weldingly fixed on raising-plate, and lower end is weldingly fixed on top board, and mutually vertical with riser, raising-plate, the top board of T shape column; Top reinforcement vertical welding be fixed on raising-plate above.

Two of push-down head reinforcement in described push-down head is with together with draw-in groove is welded and fixed, and its upper end is weldingly fixed on lower platen, and lower end is weldingly fixed on the push-down head flat board, and dull and stereotyped mutually vertical with draw-in groove, lower platen, push-down head.

The invention has the beneficial effects as follows: this frock has simple in structure, easy to operate, cheap, the advantages such as production efficiency is high, good product quality.

The specific embodiment

As shown in Figure 1, two block length strip steel plates are to the T shape and connect and be welded and fixed together, make T shape column 15.Two T shape columns 15 are weldingly fixed on two of base plate 8, seaming chuck 14 is weldingly fixed on the top of T shape column 15, push-down head 12 is installed on the middle part of T shape column 15 and can moves up and down along T shape column 15 by draw-in groove 6, the bottom on oil top 9 is packed in the middle part of base plate 8, and upper end connects the push-down head flat board 7 on push-down head 12.

As shown in Figure 1, two of the raising-plate 2 in seaming chuck 14 is weldingly fixed on the T shape column 15 on both sides and is mutually vertical with T shape column 15; Seaming chuck reinforcement 3 two ends are weldingly fixed on the riser 11 of T shape column 15, and upper end is weldingly fixed on raising-plate 2, and lower end is weldingly fixed on top board 4, and mutually vertical with riser 11, raising-plate 2, the top board 4 of T shape column 15.

Still as shown in Figure 1, on seaming chuck 14, reinforcement 1 vertical welding in top is fixed on raising-plate 2.

Still as shown in Figure 1, two of push-down head reinforcement 5 in push-down head 12 is with together with draw-in groove 6 is welded and fixed, its upper end is weldingly fixed on lower platen 13, and lower end is weldingly fixed on push-down head flat board 7, and mutually vertical with draw-in groove 6, lower platen 13, push-down head dull and stereotyped 7.

Also as shown in Figure 1, the pointer 16 that laterally is connected on the draw-in groove 6 of a side, the supporting rule 17 that is connected on the fourth plate 10 with draw-in groove 6 homonymy T shape columns 15.

As need are made the ellipse " manhole ring " of producing same specifications and models continuously, point to the position of rules 17 as long as write down pointer 16, but be pressed onto repetition of pointer 16 points to for the first time position at every turn.
