Abstract

The utility model belongs to the rolling mill manufacture technique. A lower gear shaft of a gear machine in a proposed small-sized two-high mill for labs is connected with an electromagnetic regulating speed motor (16), the other end is connected with a lower roller (2) through a coupling band (9), an upper gear shaft (12) of the gear machine is connected with an upper roller (4) through a universal coupling (10), the upper gear shaft and the lower gear shaft are connected through a pair of gear pairs (14), a slide slot which enables an upper roller bearing block to move upwards and downwards along the slide slot is arranged on a machine frame to form a structure that the upper roller can be moved upwards and downwards, a hand-operated pressing bolt (6) which enables the upper roller (4) to move downwards is arranged, simultaneously, an inner screw thread which is matched with the bolt is arranged on a machine frame cover, a nut which is used to lock the bolt (6) is arranged on the bolt (6), and a balance spring (3) which enables the upper roller to reset upwards is arranged between the upper roller bearing block and a lower roller bearing block. The small-sized two-high mill has simple structure and design, small size, low price and convenient maintenance and adjustment, and is particular applicable to plate rolling in labs with multiple types and small batches.

Description

The small-sized two-roller mill in a kind of laboratory

Technical field

The utility model belongs to the milling train manufacturing technology, relates generally to the small-sized two-roller mill in a kind of laboratory.

Background technology

During the laboratory development material, need the plate forming of material sometimes.Since the restriction of funds and the restriction in place, laboratory, and rolling stock is few in batches, and need to install cheap bar milk simple in structure.Rolling mill structure complexity in the market, price is more expensive, size is bigger.The double-roll rolling mill of market sale all adopts two Hooks coupling universal couplings.The top roll screwdown gear is comparatively complicated, is exactly that the simplest hand screw nut top roll of structure is adjusted structure, just comprises adjustment dish, handle, depress spiro rod, copper nut.Its roll balance gear is also complicated, and the simplest spring bascule of structure comprises that not only spring also has pull bar.The roll rotational speed of milling train can not be adjusted.

Summary of the invention

The purpose of this utility model promptly produces thus, proposes the small-sized two-roller mill in a kind of laboratory, makes it have characteristics simple in structure, that size is little, thereby is applicable to the plate rolling that the laboratory is little in batches.

The technical scheme that its invention task of finishing the utility model is adopted is: the small-sized two-roller mill in a kind of laboratory, the lower tooth wheel shaft of gear machine is connected with electromagnetic varispeed motor and its other end is connected with bottom roll by shaft coupling, the axle that cogs of gear machine is connected with topping roll by Hooks coupling universal coupling and makes, the lower tooth wheel shaft connects by a pair of gear pair, on frame, have and make the topping roll bearing block along its chute that slides up and down, constitute topping roll structure moving up and down, be provided with the manual depression bolt that topping roll is moved down and have the internal thread that cooperates with bolt at housing cap simultaneously, on bolt, has nut, last to its locking, be provided with the spring that topping roll is upwards resetted between the bottom roll bearing block.

The small-sized two-roller mill in the laboratory that the utility model proposed, topping roll is connected, has the chute that the topping roll bearing block slides up and down on the frame by Hooks coupling universal coupling with the axle that cogs, constitute topping roll structure moving up and down, manual bolt is set and on housing cap, has the internal thread that is mated, make the manual bolt of rotation topping roll can be pressed down and when rolling, will depress bolt locking, the back-moving spring of the setting jack-up that when depressing bolt and unclamp, topping roll can be made progress.The utility model structural design is simple, and size is little, and is cheap, is convenient to maintenance and adjustment, is specially adapted to the plate rolling that the laboratory kind is many, batch is few.
