Description

The piston ring wire production of falling from power is with passive four roller forming machines

Technical field

The utility model relates to the processing of profiled metal wire rod, the processing of the piston ring wire rod of especially falling from power.

Background technology

After the entry to WTO, the external parts of part will be also lower than the product price of domestic production with the import of direct trade mode, and domestic parts enterprises can be subject to greater impact inevitably, and kitting market also will face more keen competition.

Driven by environmental protection, energy-conservation trend, high-performance, low emission level engine are development priorities from now on.For piston ring, it be technology-intensive type be again labor-intensive product, be in the cardia of engine, the performance of engine is produced directly impact.The extensive utilization of new technology, so that car load to parts, has proposed more and more harsher requirement to piston ring especially, the piston ring industry is constantly updated product.The fall from power production procedure of piston ring: circle silk thread material is rolled into rectangle, grinds to be fallen from power by secondary operations again behind ring.Traditional mode of production has been not suitable with the modern production requirement, and operation is loaded down with trivial details, and production efficiency is low, also can't realize effective control of cost.

Summary of the invention

The purpose of this utility model is to have overcome above-mentioned not enough problem, provide a kind of piston ring wire production of falling from power with passive four roller forming machines, cooperation Direct Rolling by the special-shaped roll wire rod that goes out to fall from power, need not secondary operations, production efficiency is high, reduced greatly processing cost, the wire size fluctuation that processes is little, has improved greatly the qualification rate of product.

The technical scheme that the utility model adopts to achieve these goals is: the piston ring wire production of falling from power is with passive four roller forming machines, from being fed to discharging rough rolling device and finish-rolling device are installed successively on the body, rough rolling device adopts two large alloy rollers, and finish-rolling device adopts 3 plain-barreled rolls and profile rolled four rollers that the roll of falling from power consists of.

Described finish-rolling device top roll is the roll of falling from power, and other three rollers are plain-barreled roll, and four rollers are arranged relatively, the middle wire cross-section shape of falling from power that forms.

The utility model process equipment is to consider from variant factors such as working (machining) efficiency, quality assurance, processing cost control, reduction labour intensity, in conjunction with the size of wire rod, carries out the design of roll, is fit to very much the production of bulk article.Be embodied in following 3 points:

1, process equipment is simple: process only needs passive four roller forming machines, an employee.The employee is rolled into rectangle with circular wire rod first, and then use the roll of falling from power to roll out and fall from power, and has realized the reduction of equipment, cost of labor.

2, quality assurance, be convenient to management: process equipment is simultaneously rolling at four direction, need not to carry out separately the rolling of each face, has avoided the independent situation that technique is difficult to set when rolling.The employee only need to regulate the amount of rolling of roll, and wire rod is rolled into the desired size of product, and difficulty of processing is little, simple to operate, and processing conditions is easily controlled, and the wire size fluctuation is little, has realized the effective control to product quality.

3, reduce manufacturing procedure, boost productivity: wire rod is from dropping into until the final product moulding is all finished by roll, and the wire rod of falling from power that rolls out need not to grind moulding.Directly carry out next procedure after the coiling of piston ring wire rod, improved greatly the productivity ratio of product.Also reduced simultaneously product causes because circular flow is unfavorable draw, damage.

Description of drawings

Fig. 1 is the utility model four roller forming machine production status schematic diagrames;

Fig. 2 is the utility model finish-rolling device roll structure schematic diagram.

Among the figure: 1 actinobacillus device; 2 rough rolling devices; 3 finish-rolling devices; 4 take-up blocks; 5 take-ups; 6 bodies; 7 wire rods; 8 plain-barreled rolls; 9 rolls of falling from power.

The specific embodiment

The piston ring wire production of falling from power as shown in fig. 1 is with passive four roller forming machines, from being fed to discharging rough rolling device 2 and finish-rolling device 3 are installed successively on the body 6, rough rolling device 2 adopts two large alloy rollers, finish-rolling device 3 adopts three plain-barreled rolls 8 and profile rolled four rollers that the roll 9 of falling from power consists of, the finish-rolling device top roll is the roll 9 of falling from power, other three rollers are that plain-barreled roll 8, four rollers are arranged relatively, the middle shape of cross section that forms the wire rod 7 of falling from power.

During work as shown in Figure 1: use actinobacillus device 1 that raw material are linear in passive four roller forming machine rough rolling device 2 and finish-rolling devices 3, be wrapped in above the take-up block 4; The shape of roll of falling from power designs according to the size that wire rod requires, and regulates the position of arranging of roll according to the needed shape of cross section of product, and the slit that wire rod passes through is left in the centre, further regulates the amount of rolling of roll, meets the requirements of wire size; The driven by motor take-up block carries out take-up through take-up 5 behind the wire forming.

Claims (2)

1. the piston ring wire production of falling from power is with passive four roller forming machines, it is characterized in that: from being fed to discharging rough rolling device and finish-rolling device are installed successively on the body, rough rolling device adopts two large alloy rollers, and finish-rolling device adopts 3 plain-barreled rolls and profile rolled four rollers that the roll of falling from power consists of.
