Description

A kind of square tube crimping unit

Technical field：

The utility model is related to crimping unit field, specifically a kind of square tube crimping unit.

Background technology：

Gas circuit pipe be used for gas-cooker in, existing production method be by one section of square tube, then separately cut two pieces opened with it The rectangular slab that mouth matches, it is by welding that its is closed at both ends, but this mode not only wastes the dosage of steel, And four sides of rectangular slab need to be welded when welding, the producing efficiency for leading to gas circuit pipe is very low.

Utility model content：

The purpose of this utility model provides a kind of use wedge clamp cooperation cam and incites somebody to action exactly in order to solve existing issue Center bending of the outer wall of square tube to square tube forms flat opening, closing can be realized on one side by welding, without separately cutting Rectangular slab is cut for closure of openings, rolled steel dosage is saved, improves the square tube crimping unit of producing efficiency.

The technology solution of the utility model is as follows：

A kind of square tube crimping unit including platen and square tube, forms the square of multiple linear interval distributions on the platen Shape convex block forms the rectangular through-hole coordinated with rectangular cam sleeve on the end face of the square tube, and one end of the square tube is equipped with Flanging component, the flanging component include symmetrical rotational installation in the cam of square tube opening both sides, liftable and are symmetrically disposed on Square tube is open the wedge clamp of upper and lower, and the inclined-plane on the wedge clamp is towards square tube.

Preferably, being additionally provided with pressure plate above the square tube, the both ends of the pressure plate are fixed with leading through platen Column is fixed with installing plate between the elongated end of the guide post, cylinder is fixed between the medial surface and platen of the installing plate.

Preferably, the vertically-mounted cylinder for having its lifting of driving on the wedge clamp, the cylinder driving wedge shape Pressing plate moves in the same direction.

Preferably, the through-hole for accommodating the wedge clamp is also formed on the platen.

Preferably, the bottom surface of the cam is fixed with the shaft through platen, the elongated end of the shaft be connected with The fixed motor in platen bottom surface, the thickness of the protrusion of the cam outside introversion and extroversion by being gradually reduced.

The beneficial effects of the utility model are：Coordinate cam by the outer wall of square tube into square tube using wedge clamp Bending of being filled with admiration is open into flat, and closing can be realized on one side by welding, without separately cutting rectangular slab for closure of openings, section Rolled steel dosage is saved, improves producing efficiency.

As shown in Figs 1-4, square tube crimping unit including platen 17 and square tube 18, forms multiple straight on the platen 17 The rectangular cam 19 that line is spaced apart forms the rectangle coordinated with 19 sleeve of rectangular cam on the end face of the square tube 18 and leads to Hole, one end of the square tube 18 are equipped with flanging component, and the flanging component includes symmetrical rotational installation in the opening of square tube 18 both sides Cam 20, liftable and be symmetrically disposed on square tube 18 and be open the wedge clamp 21 of upper and lower, it is oblique on the wedge clamp 21 Face is towards square tube 18.

Specifically, 18 top of square tube is additionally provided with pressure plate 26, and the both ends of the pressure plate 26 are fixed with through platen 17 guide post 22 is fixed with installing plate 23, medial surface and the platen 17 of the installing plate 23 between the elongated end of the guide post 22 Between be fixed with cylinder, this setting further improves the stability during flanging of square tube 18, avoids the movement of its radial direction.

Specifically, the vertically-mounted cylinder for having its lifting of driving on the wedge clamp 21, the cylinder driving wedge shape Pressing plate 21 is mobile in the same direction, and the through-hole for accommodating the wedge clamp 21 is also formed on the platen 17, this setting is driven by cylinder Dynamic wedge clamp 21 lifts, and flanging is carried out to the upper and lower wall of square tube 18.

Specifically, the through-hole for accommodating the wedge clamp is also formed on the platen.

Specifically, the bottom surface of the cam 20 is fixed with the shaft 24 through platen 17, and the elongated end of the shaft 24 connects It is connected to and is gradually reduced outside by introversion and extroversion with the fixed motor in 17 bottom surface of platen, the thickness of the protrusion of the cam 20, this sets Putting the structure of middle cam makes the folding line of 18 both sides of square tube attenuate, and the opening be conducive in this way after flanging is more flat, and use is thinner Welding wire welds, and reduces the dosage and cost of welding wire.

Operation principle：The segment square tube 18 that punching finishes is placed in 26 lower section of pressure plate, rectangular cam 18 corresponds to rectangle and leads to Hole is inserted into, cylinder ejector, and pressure plate 26 compresses square tube 18, and one circle of the rotation of motor driving cam 20 makes square tube both sides bend inwards, Then wedge clamp 21 presses to the upper and lower wall of square tube 18, until its edge approaches, thereon, the control of the spacing of lower wall 1~ 1.5cm, this opening spacing are conducive to welding wire and are solded among opening completely, the quality and leakproofness of welding are improved, when one end is complete Into after flanging, come loose pressure plate 26, and square tube 18 is turned around, is repeated the above steps, and the other end is carried out flanging processing.

The above is only the preferred embodiment of the present invention, and those of ordinary skill in the art are not making creativeness All other embodiments obtained under the premise of labour should all belong to the range of the utility model protection.
