Abstract

The utility model relates to a forming device for a stainless steel ten-wave dovetail groove type corrugated floor, belonging to the field of machinery and aiming to provide a forming device for a stainless steel ten-wave dovetail type corrugated floor, which can realize one-step formation from plates to a finished product and can be used for processing long products. The forming device comprises an uncoiler, a cold bending unit, a hydraulic shearing machine, a raceway, a hydraulic station and an electric control system. The device has a reasonable structure, the produced ten-wave dovetail type floor is light (with the weight reduced by 20 percent), the noise can be reduced by 20 percent, the service life can be prolonged more than twice (40 years), the carrying capacity can be increased by 20 percent, and the working hours for vehicle body welding can be decreased by 50 percent. In order to satisfy the requirements for design of a series of extremely demanding technical indicators, an SUS301L high-strength stainless steel plate and the reverse arc bending formation process are adopted, and formation is realized via gradual rolling with 42 rolling machines and 3000 molds. When the ten-wave dovetail type corrugated floor is used by a novel subway vehicle, three 22-meter welding seams can be eliminated, the production efficiency can be increased greatly, the cost can be reduced, and the strength and sealing performance of the overall vehicle can be improved.

Description

Stainless steel ten ripple dovetail groove rolling country sheet metal forming devices

Technical field

The utility model belongs to mechanical field.

Background technology

The production equipment on dovetail groove floor has many, but the dovetail groove floor of producing is heavier from body, installs extremely inconvenient; And damage easily, service life is short, the cost that increases virtually; And the existing equipment production process is complicated, and continuous productive process property is relatively poor continuously, so can only produce short dovetail groove floor; In use increase weld seam, just increase workload, reduced efficient and reduced sealing property and intensity.

Summary of the invention

The purpose of the utility model provide a kind of from sheet material to the finished product one-shot forming, and can process stainless steel ten ripple dovetail groove rolling country sheet metal forming devices than long products.

The utility model is made up of uncoiler, clod wash unit, hydraulic shearer, raceway, Hydraulic Station and electric-control system;

On the support of a, uncoiler slideway is arranged, slide block matches with slideway, and slide-bar passes slide block, and taper iron is installed on slide-bar, and the motor that slide block walking and slide-bar are rotated is installed on support;

42 road horizontal roller framves are installed on the support of b, clod wash unit, and per pass horizontal roller frame is that two roller framves are formed;

The structure of 1. single horizontal roller frame is: top shoe and sliding block that the inboard taxiway of support cooperates, last adjusting lever be through being threaded on the support, and be connected with top shoe, and following adjusting lever is through being threaded in the support lower end, and be connected with sliding block;

2. the top shoe of two of per pass horizontal roller frame roller framves is equipped with topping roll, and the sliding block of two roller framves of per pass horizontal roller frame is equipped with bottom roll;

3. topping roll is connected with universal drive shaft respectively with bottom roll, and universal drive shaft is connected with the power input system;

C, raceway structure are: axle is connected with the cylinder roller on the sidewall of frame upper end.

The utility model is rational in infrastructure, ten ripple dovetail floor lightweights (loss of weight 20%) of making, and noise reduction (reducing by 20%), double service life above (40 years), handling capacity of passengers increases by 20%, reduces by 50% during the car body Welder.In order to satisfy a series of extremely harsh technical indicators of design, select the SUS301L high-strength stainless steel sheet for use, adopt arc length recurvation shaping design technology, and through 42 road milling trains, 3000 moulds, progressively rolling formations.The novel subway vehicle adopts ten ripple dovetail groove corrugated floors, can reduce by 3 22 meters long weld seams, has improved production efficiency greatly, reduces cost, and has improved the intensity and the sealing property of car load simultaneously.
