Description

Hand-held double-roller sheet curling mechanism

Technical Field

The utility model relates to a curling mechanism technical field, especially two roller sheet metal curling mechanisms of hand-held type.

Background

When steel plates or aluminum plates are used for manufacturing some products (such as signboards) they are usually cut from thin plates, but the edges are sharp and rough, which is prone to scratching, and therefore the edges need to be rolled up.

But the mode of wrapping is very laborious, and the wrapping is difficult to ensure to be linear; for this purpose, a method of folding the edge is adopted, i.e., first scribing and then folding the edge in a vertical manner in a little by little. Generally, the folding is carried out by using a clip to clamp the folding point by point, and the working efficiency is low.

This scheme special design hand-held type two roller sheet metal turn-up mechanism can fold the limit fast and roll up, and the width of folding as required adapts to the adjustment.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome prior art's shortcoming, provide simple structure, can turn up fast, can adjust the two roller sheet metal turn-up mechanisms of hand-held type of width.

The purpose of the utility model is realized through the following technical scheme: the handheld double-roller sheet curling mechanism comprises a handheld piece and two roller pieces; the two roller pieces are arranged on the handheld piece in a mutually clearance mode; the roller parts of the two roller members clamp the edges of the sheet materials to roll back and forth for hemming and folding.

Furthermore, the two roller pieces are arranged on the hand-held piece through the long waist-shaped through hole, and the two roller pieces are perpendicular to the length direction of the hand-held piece.

Further, the two roller members comprise a roller part and a shaft part;

the shaft part penetrates through the long waist-shaped through hole, one end of the shaft part is provided with a roller part, and the other end of the shaft part is locked through a nut.

Furthermore, the hand-held piece is provided with an adjusting hole communicated with the long waist-shaped through hole along the length direction;

and an ejector rod in threaded fit is placed in the adjusting hole, one end of the ejector rod is abutted to the roller piece, the other end of the ejector rod is leaked out of the hand-held piece, and the ejector rod is rotated to adjust the gap width of the two roller pieces.

Furthermore, the two roller pieces are positioned at one end of the hand-held piece, and the other end of the hand-held piece is a handle.

Preferably, the roller part is a bearing.

The utility model has the advantages of it is following:

(1) the handheld piece is provided with the two roller pieces which are mutually in a clearance, the edges of the plates are clamped by the clearance, the roller pieces enable the roller pieces to roll along the edges of the plates, and meanwhile, the handles are gradually tilted, so that the plates can be rolled quickly, and the plate rolling device is simple and convenient;

(2) the roller part and the shaft part in the roller piece are structurally arranged, so that different numbers of roller parts can be installed according to the required rolling width.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the curling edge of the present invention;

in the figure: 1-hand piece, 101-long waist-shaped through hole, 2-roller piece, 201-roller part, 202-shaft part, 203-nut and 3-ejector rod.

Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1 and 2, the hand-held double-roll sheet hemming mechanism includes a hand-held member 1, two roller members 2; a long waist type through hole 101 is opened at one end of the hand piece 1, and the two roller pieces 2 are installed in the long waist type through hole 101 with a gap therebetween. The other end of the hand piece 1 is a handle. In operation, the roller portions 201 of the two roller members 2 clamp the edges of the sheet material and roll back and forth to perform hemming folding.

In the scheme, the two roller pieces 2 comprise a roller part 201 and a shaft part 202; wherein, the shaft part 202 passes through the long waist-shaped through hole 101, both ends of the shaft part leak out of the hand piece 1, one end of the shaft part is provided with a roller part 201, and the other end of the shaft part is locked by a nut 203.

In this embodiment, the roller portion 201 is preferably a bearing. When the edges with different widths need to be rolled, the nut 203 is unscrewed, the shaft part 202 is taken out, different numbers of bearings are sleeved according to actual conditions, and then the bearings pass through the long-waist-shaped through hole 101 and are locked and installed through the nut 203.

An adjusting hole is formed in the center of the hand piece 1 along the length direction, and the adjusting hole is communicated with the long waist-shaped through hole 101; a push rod 3 which can be screwed is arranged in the adjusting hole, one end of the push rod 3 is propped against the roller piece 2, and the other end of the push rod is leaked out of the hand piece 1. Namely, the width of the gap between the two roller parts 2 is adjusted through the mandril 3 so as to meet the requirements of plates with different thicknesses.

In this embodiment, the adjustment hole is the unthreaded hole, and the welding has the screw hole spare that corresponds with the adjustment hole in the end department of handheld piece 1, ejector pin 3 and screw hole spare cooperation installation.

In this embodiment, the handpiece 1 is preferably made of square steel.

The ejector rod 3 is provided with a plurality of modes: optionally, a top bar 3 is arranged at one end of the hand-held piece 1, the top bar 3 only abuts against one roller piece 2, and the other roller piece 2 is directly abutted against the end face of the kidney-shaped hole (as shown in fig. 1 and 2); optionally, two ejector rods 3 are arranged at two ends of the hand piece 1, and each ejector rod correspondingly abuts against one roller piece 2; alternatively, a plunger 3 can be arranged to abut against one roller element 2, and the other roller element 2 is abutted by a spring, which is arranged in the hand piece 1 and the end of which is sealed and blocked.

The scheme is mainly used for curling color steel and profiled steel plates with the thickness of less than 0.4-1.2 mm.

The above examples only represent preferred embodiments, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
