Abstract

The invention discloses a leveling machine, which comprises a framework. A plurality of upper leveling rolls are movably arranged on the framework, a plurality of lower leveling rolls in stagger arrangement with the upper leveling roll are also arranged on the framework, the lower leveling rolls are connected with a power unit, an upper prepressing roll is movably arranged at a feed end of the framework, sliding guide blocks are respectively arranged at two ends of the upper prepressing roll, a support plate is arranged below the sliding guide blocks on the framework, and a lower prepressing roll is arranged under the upper prepressing roll on the framework. The upper prepressing roll is driven by two oil cylinders which are respectively arranged above the two sliding guide blocks, pistons of the oil cylinders are connected with the sliding guide blocks through piston joints, racks are arranged on sides of the sliding guide blocks, and gears meshing with the racks are respectively arranged two ends of a synchronous shaft arranged on the framework. By the aid of the upper prepressing roll and the lower prepressing roll arranged on the leveling machine, feeding is smooth, and the production efficiency of the leveling machine is increased.

Description

A kind of evener

Technical field

The present invention relates to a kind of evener.

Background technology

Evener is to be used for irregular sheet metal, through the extruding of top and bottom rolls with certain thickness band or sheet material, thereby reaches smooth effect.

Evener commonly used comprises frame, is movably set with some plain-barreled rolls of going up on the frame, also is provided with some plain-barreled rolls down on the frame; Following plain-barreled roll is connected with power set; This evener is when the raw material that feeding is curled, and raw material is difficult for getting between the upper and lower plain-barreled roll, influences production efficiency.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of pan feeding smooth and easy, evener rapidly and efficiently.

For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of evener, comprise frame, and be movably set with some plain-barreled rolls of going up on the frame; Also be provided with the staggered following plain-barreled roll of installing of some and last plain-barreled roll on the frame; Following plain-barreled roll is connected with power set, is positioned at feed end on the said frame and is movably set with pony press, and last pony press two ends are respectively arranged with the slide-and-guide piece; Below the slide-and-guide piece, be provided with supporting plate on the said frame, below last pony press, be provided with pony press down on the said frame.

The said pony press of going up adopts two hydraulic oil cylinder driving; Two oil cylinders are separately positioned on two slide-and-guide piece tops; And oil cylinder piston is connected with the slide-and-guide piece through piston joint; The side of said slide-and-guide piece is provided with tooth bar, and said frame is provided with synchronizing shaft, and the synchronizing shaft two ends are respectively arranged with the gear that matches with tooth bar.

Said go up plain-barreled roll, down plain-barreled roll, go up pony press, pony press all adopts hollow roller down.

The invention has the beneficial effects as follows: reach pony press down owing to be provided with pony press, make pan feeding smooth and easy, improved the production efficiency of evener.

Because the side of said slide-and-guide piece is provided with tooth bar, said frame is provided with synchronizing shaft, and the synchronizing shaft two ends are respectively arranged with the gear that matches with tooth bar.Even the process of two oil cylinders is asynchronous, last pony press is under the effect of synchronizing shaft and rack-and-pinion, and the decrease speed at two ends also is the same, has avoided the jam in the decline process, has guaranteed the precompressed effect.

Because last plain-barreled roll, down plain-barreled roll, go up pony press, pony press all adopts hollow roller down, has alleviated complete machine weight greatly, has saved manufacturing cost.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Fig. 2 is that the partial structurtes sketch map is looked on the left side of Fig. 1.

Fig. 3 is that A-A cuts open partial schematic diagram.

Among Fig. 1 to Fig. 3: 1. frame, 2. go up plain-barreled roll, 3. descend plain-barreled roll, 4. go up pony press, 5. slide-and-guide piece, 6. supporting plate 7. plays pony press, 8. oil cylinder, 9. piston joint, 10. tooth bar, 11. synchronizing shafts, 12. gears.

The specific embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.

Shown in Fig. 1-3, a kind of evener comprises frame 1; Be movably set with some plain-barreled rolls 2 of going up on the frame 1, also be provided with the some and last plain-barreled roll 2 staggered following plain-barreled rolls of installing 3 on the frame 1, following plain-barreled roll 3 is connected with power set; Be positioned at feed end on the said frame 1 and be movably set with pony press 4; Last pony press 4 two ends are respectively arranged with slide-and-guide piece 5, below slide-and-guide piece 5, are provided with supporting plate 6 on the said frame 1, below last pony press 4, are provided with pony press 7 down on the said frame 1.The said pony press 4 of going up adopts two oil cylinders 8 to drive; Two oil cylinders 8 are separately positioned on two slide-and-guide piece 5 tops; And oil cylinder 8 pistons are connected with slide-and-guide piece 5 through piston joint 9; The side of said slide-and-guide piece 5 is provided with tooth bar 10, and said frame 1 is provided with synchronizing shaft 11, and synchronizing shaft 11 two ends are respectively arranged with the gear 12 that matches with tooth bar 10.Said go up plain-barreled roll 2, down plain-barreled roll 3, go up pony press 4, pony press 7 all adopts hollow roller down.

Reach pony press 7 down owing to be provided with pony press 4, make pan feeding smooth and easy, improved the production efficiency of evener.

Because the side of said slide-and-guide piece 5 is provided with tooth bar 10, said frame 1 is provided with synchronizing shaft 11, and synchronizing shaft 11 two ends are respectively arranged with the gear 12 that matches with tooth bar 10.Even the process of two oil cylinders 8 is asynchronous, last pony press 4 is under the effect of synchronizing shaft 11 and gear 12 tooth bars 10, and the decrease speed at two ends also is the same, has avoided the jam in the decline process, has guaranteed the precompressed effect.

Because last plain-barreled roll 2, down plain-barreled roll 3, go up pony press 4, pony press 7 all adopts hollow roller down, has alleviated complete machine weight greatly, has saved manufacturing cost.
