Background

The main material of the light steel villa, also called light steel structure house, is a light steel keel synthesized by galvanized steel strips through a cold rolling technology. The light steel structure house has light dead weight which is only about one fifth of that of a brick-concrete structure house and about one eighth of that of a reinforced concrete structure house, so that the foundation construction cost can be greatly reduced, and the light steel structure house can be generally provided with a strip foundation.

In the process of producing the keel, the galvanized steel strip needs to be cut and then bent into a corresponding section, for example, an angle steel-shaped structure. In the process of processing the galvanized steel strip, an unreeling machine/an unreeling machine is needed to unreel the galvanized steel strip coil. The existing unreeling machine/unreeling machine usually adopts a support arm to roll off the galvanized steel strip, and in order to prevent the galvanized steel strip from moving along the length direction of the support arm, the galvanized steel strip is usually blocked by a baffle plate; for example, the fully automatic heavy duty unwinder of tonneau mechanical equipment manufacturing ltd.

Because there are various specifications in the width of galvanized steel strip, for guaranteeing that unreeling machine baffle 10 rolls up the galvanized steel strip and supports tightly, just also can't utilize the mode of pin cooperation pinhole to fix, because the interval between this kind of fixed mode pinhole will set up more than 1cm at least, this easily causes the galvanized steel strip to roll up and takes place the swing at the rotation in-process. Usually, a guide rod 11 with a circular cross section is additionally arranged at a support arm of the unreeling machine, and as shown in fig. 1, a through hole matched with the guide rod 11 is arranged at a baffle 10 of the unreeling machine; utilize anchor clamps to support tight unreeling machine baffle 10, anchor clamps are by the cover pipe box 1 and the handle 2 of cover outside guide arm 11 and constitute, and one side of pipe box 1 is provided with the open slot that supplies handle 2 head end activity, and the prelude of handle 2 is articulated with pipe box 1 in open slot department to the head end of handle 2 is the segment column structure. After the baffle 10 of the unreeling machine is tightly close to the galvanized steel strip coil, the pipe sleeve 1 is sleeved outside the guide rod 11, and the pipe sleeve 1 is abutted against the baffle 10 of the unreeling machine; then the tail end of the handle 2 is pressed downwards to enable the handle 2 to be arranged vertically, in the process, the head end of the handle 2 with the spherical structure can continuously abut against the side wall of the guide rod 11, and finally the pipe sleeve 1 and the guide rod 11 are locked by the aid of interference fit. When the clamp needs to be opened, the handle 2 in the vertical state only needs to be pulled back to the original state.

Although the structure is simple, the head end of the handle 2 is easy to wear because the handle is tightly pressed in an interference fit manner; the handle 2 needs to be replaced with a new one at intervals, which is high in consumption; and, the later the more the head end of handle 2 is by the more serious of wearing and tearing, the locking effect can descend, has the potential safety hazard.

Example 1

As shown in fig. 2 to 8, the jig for the baffle of the unreeling machine comprises an inner sleeve 20 and a rotating sleeve 50 sleeved outside the inner sleeve 20, the inner sleeve 20 comprises a tube body 21, the cross section of the inner circumference of the tube body 21 is circular, an external thread 211 is arranged on the outer circumference of the tail part of the tube body 21, a plurality of opening slits 221 arranged along the axial direction of the tube body 21 are arranged on the head part of the tube body 21, one end of each opening slit 221 extends to the head end of the tube body 21, a gap is arranged between the other end of each opening slit 221 and the external thread 211, the head part of the tube body 21 is divided into a plurality of movable parts 22 by the opening slits 221, the opening slits 221 are arranged at equal intervals, a first conical surface 222 is arranged on the outer circumference of the head part of the tube body 21, a gap is arranged between the large end of the first conical surface 222 and the head end of the tube body 21, the large end of the first conical surface 222 is the end with the largest diameter, the small end of the first conical surface 222 is the end with the smallest diameter, the large end of the first conical surface 222 faces the head end of the tube body 21, the small end of the first conical surface 222 faces the external thread 211, the head part of the tube body 21 is further sleeved with a sliding sleeve 30 for tightening the movable part 22, and the inner periphery of the sliding sleeve 30 is provided with a second conical surface 31; the rotating sleeve 50 comprises a sleeve body 51, the inner wall of the sleeve body 51 is provided with an internal thread 511 matched with the external thread 211, the head end of the sleeve body 51 is provided with a circular convex ring part 52, the convex ring part 52 is connected with the sleeve body 51 into a whole, and the convex ring part 52 is arranged between the sliding sleeve 30 and the sleeve body 51.

The inner sleeve 20, the sliding sleeve 30 and the rotary sleeve 50 are made of metal materials, preferably iron materials with low cost such as cast iron and carbon steel.

Due to the presence of the open seam 221, the movable portion 22 is allowed to swing to a certain extent. When all the movable parts 22 swing synchronously, the tightening and expanding actions can be completed.

The taper angle of the first taper surface 222 is delta, the taper angle of the second taper surface 31 is alpha, and delta-alpha is more than or equal to 0 degrees and less than or equal to 6 degrees.

The specific use method of the clamp for the baffle of the unreeling machine is as follows:

1) when the unreeling machine baffle 10 penetrates through the guide rod 11, the unreeling machine baffle 10 abuts against the galvanized steel strip coil, the inner sleeve 20 is firstly sleeved outside the guide rod 11, and the inner sleeve 20 is in clearance fit with the guide rod 11.

2) The second tapered surface 31 of the sliding sleeve 30 contacts with the first tapered surface 222 of the inner sleeve 20 because the sliding sleeve 30 is sleeved outside the inner sleeve 20. Since the rotary sleeve 50 and the inner sleeve 20 are threadedly coupled with each other by means of the external and internal threads 211 and 511. When the collar portion 52 continuously pushes the sliding sleeve 30 forward by rotating the rotating sleeve 50.

3) When the head of the tube 21 is in an initial state (i.e. the head of the tube 21 is not subjected to the binding force of the sliding sleeve 30), delta is larger than alpha. If δ is α in the initial state, even if the sliding sleeve 30 is pushed, the head of the pipe body 21 is not tightened. Only delta is larger than alpha, when the sliding sleeve 30 is continuously pushed, the movable part 22 is continuously contracted towards the inner circumferential direction of the tube body 21 under the interaction of the first conical surface 222 and the second conical surface 31, and finally, the movable part 22 can be ensured to be tightly attached to the side wall of the guide rod 11. When the rotating sleeve 50 is rotated and the sliding sleeve 30 cannot be pushed to move forwards, the head of the pipe body 21 is completely tightened on the guide rod 11, that is, the baffle of the unreeling machine is locked on the guide rod 11 by the clamp, so that the baffle 10 of the unreeling machine is prevented from moving again.

Because the relative position between the clamp for the unreeling machine baffle and the guide rod 11 can be adjusted at will, even if the width of the galvanized steel strip changes, the unreeling machine baffle 10 can be ensured to tightly abut against the galvanized steel strip, and the follow-up galvanized steel strip is prevented from swinging in the rotating process.

When the head of the tube 21 is completely tightened against the guide rod 11, the first tapered surface 222 and the second tapered surface 31 are parallel to each other, i.e., δ ═ α. δ must not be too large, which would otherwise cause the thickness of the movable portion 22 to be too thick, which is detrimental to the swinging of the movable portion 22.

Further, the inner wall of the tube 21 is provided with at least one rib 212 arranged along the axial direction of the tube 21. The side wall of the guide rod 11 is provided with an axial slot 111 for the rib 212 to move, as shown in fig. 6. The length direction of the axial clamping groove 111 is parallel to the axial direction of the guide rod 11, and the end parts of the axial clamping groove 111 extend to the end parts of the guide rod 11.

When the inner sleeve 20 is sleeved outside the guide rod 11, the rib 212 is aligned with the axial clamping groove 111, and under the matching of the rib 212 and the axial clamping groove 111, the relative rotation between the inner sleeve 20 and the guide rod 11 can be effectively prevented, so that the subsequent rotation of the rotary sleeve 50 is facilitated to complete the locking operation.

Further, the sleeve body 51 is a more labor-saving rotary sleeve body; the outer part of the sleeve body 51 is provided with a plurality of handles 40, and the tail end of each handle 40 is fixedly connected with the sleeve body 51.

Further, in order to prevent the rotary sleeve 50 from interfering with the head of the inner sleeve 20 during rotation; the inner diameter of the collar portion 52 is greater than or equal to the maximum outer diameter of the pipe body 21.

Example 2

As shown in fig. 10, the inner wall of the head of the tube 21 is provided with a plurality of annular grooves 223 along the inner circumference of the tube 21, and the annular grooves 223 have a semicircular cross section.

The annular groove 223 is advantageous for the movable portion 22 to deform so as to urge the movable portion 22 to abut against the guide rod 11, so that the fixing structure between the head portion of the inner sleeve 20 and the guide rod 11 is more stable.

Example 3

When the fit clearance between the inner diameter of the pipe body 21 and the guide rod 11 is large, as shown in fig. 9, the annular groove 223 is provided with an annular metal ring 60.

The metal ring 60 is preferably made of iron material such as cast iron and carbon steel.

Since the movable portion 22 can swing, that is, the head of the tubular body 21 can be expanded, the metal ring 60 can be inserted from the inside of the tubular body 21; when the metal ring 60 is caught at the annular groove 223, the movable portion 22 is released, i.e., the fixing of the metal ring 60 at the annular groove 223 is completed.

When the inner sleeve 20 is sleeved outside the guide rod 11, the metal ring 60 is also sleeved outside the guide rod 11; after tightening of the nose of the inner sleeve 20, the metal ring 60 acts as a washer, enabling the fixation between the nose of the inner sleeve 20 and the guide rod 11 to be more stable.

Example 4

In embodiment 3, as shown in fig. 10, an annular magnet 70 is coaxially provided at the rear end of the pipe body 21, and the magnet 70 is fixedly connected to the rear end of the pipe body 21. To avoid interference, the inner diameter of magnet 70 is greater than or equal to the inner diameter of the tail end of tube 21, and the outer diameter of magnet 70 is less than the minimum value of the outer diameter of the tail end of tube 21.

When the inner sleeve 20 is sleeved outside the guide rod 11, the magnet 70 is also sleeved outside the guide rod 11; and the magnet 70 does not interfere with the threaded connection between the rotating sleeve 50 and the inner sleeve 20.

The magnet 70 is preferably a neodymium iron boron magnet, and under the adsorption of the magnet 70, the metal ring 60 is more difficult to fall off from the inner part of the inner sleeve 20, so that the metal ring 60 is prevented from being lost when the clamp for the baffle of the unreeling machine is not used.

In the above embodiment, the fixture for the unreeling machine baffle is reasonable in structure and convenient to use, the fixing structure between the fixture and the guide rod 11 is stable, the relative position between the fixture and the guide rod 11 can be adjusted at will, even if the width of the galvanized steel strip changes, the unreeling machine baffle 10 can conveniently roll the galvanized steel strip tightly, and the follow-up galvanized steel strip is prevented from swinging in the rotating process.

Compared with the existing clamp, the clamp for the baffle of the unreeling machine is not easy to generate loss and has long service life.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
