The expansion and contraction mechanism comprises a hollow main shaft arranged on a frame, wherein the end part of the main shaft is provided with a movable sleeve; a pull rod is inserted into the main shaft; the end part of the movable sleeve is provided with a front cover; one end of the pull rod is connected with the front cover, and the other end of the pull rod is provided with a driving device; a plurality of rows of wedged lower slide blocks are uniformly distributed in the circumferential direction of the movable sleeve; the lower slide blocks are provided with guide grooves; the main shaft is further provided with a baffle plate; an arc-shaped expansion and contraction block is movably arranged on the baffle plate; the outer side of the arc-shaped expansion and contraction block is provided with a movable baffle plate; the inner side of the arc-shaped expansion and contraction block is provided with a plurality of wedged upper slide blocks which are matched with the lower slide blocks; and the upper slide blocks are provided with bumps which are matched with the guide grooves. The utility model provides an expansion and contraction mechanism of an uncoiling machine, which is stressed stably in an expansion and contraction process, has large bearing force, is prevented from being deformed easily and has high working efficiency of a driving device.
Description
Technical field
The utility model relates to uncoiler, relates in particular to a kind of breathing mechanism of uncoiler.
Background technology
The sheet material of thinner thickness and wire rod baling usually time the, the especially sheet material of metal or wire rod on the market, will process when these materials needs through uncoiler the sheet material or the wire rod of rolling are opened earlier often.Uncoiler breathing mechanism commonly used is as shown in Figure 1; This breathing mechanism utilizes the pull bar drive link to realize opening of breathing piece or closed; The stressed of the connector at connecting rod two ends (connecting rod base, breathing piece) constantly changing at work, and the power that the connecting rod two ends receive also changes, and is prone to make rod deformation; And connecting rod needs pull bar to apply very big driving force; Thereby just can overcome the breathing piece its rotatory force that applies is driven the motion of breathing piece, so the drive unit of drive stay (being generally oil cylinder) need be selected the bigger drive unit of pulling force for use, the operating efficiency of drive unit is not high.
The utility model content
The utility model technical problem to be solved is: provide stability under loading, bearing capacity in a kind of breathing process greatly, the breathing mechanism of the uncoiler of the high efficiency of not yielding, drive unit.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of breathing mechanism of uncoiler comprises the hollow spindle that is arranged on the frame; Spindle nose is provided with and moves cover, is equipped with pull bar in the main shaft, moves the cover end and is provided with protecgulum; Pull bar one end is connected with protecgulum, and the pull bar other end is provided with drive unit, and said mobile putting circumferentially is evenly equipped with plurality of rows contract type sliding block; Said sliding block is provided with gathering sill; Also be provided with baffle plate on the said main shaft, be movably set with arc breathing piece on the baffle plate, arc breathing piece arranged outside has sideboard; Arc breathing piece inboard is provided with some contract type top shoes that match with sliding block, and top shoe is provided with the projection that matches with gathering sill.
Two ends are respectively arranged with wear-resistant sleeve in the said main shaft.
Gathering sill cross section on the said sliding block is trapezoidal, and the projection on the said top shoe is a respective shapes.
Said drive unit is oil cylinder or cylinder.
The beneficial effect of the utility model is: cooperate because upper and lower slide block is a contract type ramp type, breathing mechanism accomplishes expansion and shrinks when two slide block relative motions, and upper and lower slide block contract type structural bearing capacity is big, not yielding, stability under loading in the breathing process; And because the gathering sill cross section on the sliding block is trapezoidal, the projection on the said top shoe is a respective shapes, plays guide effect and ability snap close each other when the dovetail type of slide block is engaged in two slide block relative motions up and down; And pull bar only need drive sliding block and overcome the friction working between upper and lower slide block, and required driving force is less, can select the less drive unit of driving force for use, the high efficiency of drive unit.
Description of drawings
Fig. 1 is the structural representation of the mechanism of breathing described in the background technology.
Fig. 2 is the structural representation of the utility model.
Among Fig. 1 to Fig. 2: 1. frame, 2. main shaft 3. moves cover, 4. pull bar, 5. protecgulum, 6. oil cylinder, 7. sliding block, 8. baffle plate, 9. arc breathing piece, 10. sideboard, 11. top shoes, 12. wear-resistant sleeves.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
As shown in Figure 2, a kind of breathing mechanism of uncoiler comprises the hollow spindle 2 that is arranged on the frame 1; Main shaft 2 ends are provided with moves cover 3, is equipped with pull bar 4 in the main shaft 2, moves cover 3 ends and is provided with protecgulum 5; Pull bar 4 one ends are connected with protecgulum 5, and pull bar 4 other ends are provided with driving oil cylinder 6, circumferentially are evenly equipped with plurality of rows contract type sliding block 7 on the said mobile cover 3; Said sliding block 7 is provided with the cross section and is trapezoidal gathering sill; Also be provided with baffle plate 8 on the said main shaft 2, be movably set with arc breathing piece 9 on the baffle plate 8, arc breathing piece 9 arranged outside have sideboard 10; Arc breathing piece 9 inboards are provided with some contract type top shoes 11 that match with sliding block 7, and top shoe 11 is provided with the projection that matches with gathering sill.Two ends are respectively arranged with wear-resistant sleeve 12 in the said main shaft 2.
Cooperate because upper and lower slide block 7 is a contract type ramp type, breathing mechanism accomplishes expansion and shrinks when two slide block relative motions, and upper and lower slide block 7 contract type structural bearing capacities are big, not yielding, stability under loading in the breathing process; And because the gathering sill cross section on the sliding block 7 is trapezoidal, the projection on the said top shoe 11 is a respective shapes, plays guide effect and ability snap close each other when the dovetail type of slide block 7 is engaged in two slide block relative motions up and down; And 4 on pull bar needs to drive the friction working that sliding block 7 overcomes 7 of upper and lower slide blocks, and required driving force is less, can select the less drive unit of driving force for use, the high efficiency of drive unit.
