Abstract

The utility model provides a steel reinforcement connecting sleeve forging forming device, which is characterized by comprising a rough forging mold and finish forging mold, wherein the rough forging mold comprises a rough female mold with a through hole, a rough male mold matched with the upper part of the rough female mold, and a cushion block matched with the lower part of the rough female mold; and the finish forging mold comprises a finish female mold with a through hole, a finish male mold matched with the upper part of the finish female mold, and a perforated mat matched with the lower part of the finish female mold and provided with a through hole. According to the utility model, the hot-rolled round steel segment blank is placed in the rough forging mold and is formed to form a cup-shaped piece, and the cup-shaped piece is placed in the finish forging mold and formed to form a hollow sleeve, so that the production efficiency of the steel reinforcement straight thread connecting sleeve is greatly improved, the material utilization rate is effectively improved, the material waste is reduced and the production cost is controlled.

Description

Reinforcing steel bar connecting sleeve tube excellent suitability for press forming device
Technical field
The utility model relates to the excellent suitability for press forming device of a kind of shaped device, particularly a kind of reinforcing steel bar connecting sleeve tube, belongs to Machine Design manufacturing technology field.
Background technology
Modern architecture all adopts the part of armored concrete as building structure, because reinforced concrete structure has characteristics such as intensity height, toughness be big, so be commonly used to make up skyscraper.If concrete is the blood and the meat of building, reinforcing bar is exactly the muscles and bones and the ligament of whole building so.Existing hot rolled ribbed steel bar for building in use often want many connections, and tapped branch sleeve is exactly to connect the special connecting piece of reinforcing bar in twos.Making at present the reinforced bar straight thread branch sleeve, is that raw material carries out machining and gets with thick-walled pipe or hot rolled circular steel generally.Because thick-walled pipe exists unstable properties, high, the not congruent unfavorable factor of specification of cost, so the reinforced bar straight thread branch sleeve is generally processed without thick-walled pipe.Usually with the hot rolled circular steel raw material, through blanking, boring, Vehicle Processing cylindrical, end face and chamfering, reprocessing internal thread and getting.Because the maximum weak point that drilling machine boring exists is that production efficiency is low, only hundreds of of every bench drill overall output per manshifts, stock utilization is also low simultaneously, and utilization rate causes the manufacturing cost of branch sleeve to increase less than 55%, costs an arm and a leg.Therefore be necessary prior art is improved.
Summary of the invention
Low for solving the operating efficiency that existing reinforced bar straight thread branch sleeve adopts drilling machine boring to be brought, stock utilization is low, problems such as cost height, and the utility model provides a kind of excellent suitability for press forming device of reinforcing steel bar connecting sleeve tube.
The utility model is accomplished through following technical proposal: a kind of excellent suitability for press forming device of reinforcing steel bar connecting sleeve tube; It is characterized in that it comprises rough forge mould and finish forge mould; Said rough forge mould comprises the thick die of establishing through hole on it; Thick punch that connects with thick die top and the cushion block that connects with thick die bottom; Said finish forge mould comprises the smart die of establishing through hole on it; The smart punch that connects with smart die top; And connect with smart die bottom its on establish the perforation pad of through hole; So that under the forcing press effect, through the rough forge mould hot rolled circular steel section base is forged into cup shell, through finish forge mould cup shell is forged into hollow sleeve again.
Said thick punch is a vertical bar, and the upper end of bar is the major diameter termination, and the lower end of bar is minor diameter forging and pressing heads, forges into cup shell so that will put into the hot rolled circular steel section base of thick die.
Said cushion block is a vertical bar, and the lower end of bar is made as the major diameter base plate, so that through cushion block the cup shell that forges and presses is ejected thick die from bottom to top.
Said smart punch is a vertical bar, and the upper end of bar is the major diameter termination.
Said perforation pad is located in the respective slot of smart die bottom; And the through hole on it is communicated with through hole on the smart die, so that after cup shell put into the through hole of smart die, under the forcing press effect; Through thick punch the cup base pressure of cup shell is worn, to form hollow sleeve.
The utlity model has advantage and effect: adopt such scheme, only need hot rolled circular steel section base is put into the rough forge mould, forge into cup shell earlier; Again this cup shell is put into finish forge mould; Forge into hollow sleeve, not only improved the make efficiency of reinforced bar straight thread branch sleeve greatly, and effectively improved the utilization rate of material; Reduce waste of material, the control production cost.Be that a desirable reinforcing steel bar connecting sleeve tube is used the excellent suitability for press forming device in fact.
Description of drawings
Fig. 1 is the rough forge mould structure sketch map of the utility model;
Fig. 2 is the finish forge mould structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
The excellent suitability for press forming device of the reinforcing steel bar connecting sleeve tube that the utility model provides comprises rough forge mould and finish forge mould, and the rough forge mould comprises the thick die 2 of establishing through hole 3 on it; Thick punch 4 that connects with thick die 2 tops and the cushion block 1 that connects with thick die 2 bottoms, thick punch 4 is a vertical bar; The upper end of bar is the major diameter termination, and the lower end of bar is minor diameter forging and pressing 5, and cushion block 1 is a vertical bar; The lower end of bar is made as major diameter base plate 6, like Fig. 1; Finish forge mould comprises the smart die 9 of establishing through hole 10 on it; The smart punch 11 that connects with smart die 9 tops, and connect with smart die 9 bottoms its on establish the perforation pad 8 of through hole 7, smart punch 11 is a vertical bar; The upper end of bar is the major diameter termination; Perforation pad 8 is located in the respective slot 12 of smart die 9 bottoms, and the through hole on it 7 is communicated with through hole 10 on the smart die 9, like Fig. 2.Under the forcing press effect,, the hot rolled circular steel section base of putting into thick die 2 is forged into cup shell A through cooperating of thick punch 4 and thick die 2; Like Fig. 1; And after by cushion block 1 cup shell A being ejected from bottom to top, again through the cooperating of smart die 9 and smart punch 11, with the cup end B of the cup shell A that puts into smart die 9; After forging and pressing, separate forming hollow sleeve C, like Fig. 2 with wall of cup.
