Description

Detailed Description of the Invention

[0001]

[Industrial field of application] A plate A in which the edge is bent into three folds (hemming) to form a three-fold edge portion, and a plate B in which the edge is bent at a right angle to form a right-angled edge portion. , With the tip of the right-angled edge of the plate B fitted in the upper groove of the three-fold edge of the plate A, bend the tips of the three-fold edges at an inward right angle to form the plates A and B. (EN) Provided is a binding and shaping means for two plates, which binds (seaming) and shapes the binding portion beautifully and firmly.

[0002]

2. Description of the Related Art Conventionally, various means have been used as means for binding (seaming) sheet metal members such as steel thin plates and stainless thin plates. Among them, mainly the edge members of two plates A and B are used. As a means to bind at a right angle,

A plate A in which the edge is folded into three folds (hemming) to form a three-fold edge a, and a plate B in which edges are bent at a right angle (hemming) to form a right-angled edge b. With the tip b ₁ of the right-angled edge portion b of the plate B fitted in the upper clear groove a ₁ of the three-fold edge portion a of the plate A, the tip a ₂ of the three-fold edge portion a is turned inward at a right angle. A binding means for the plates A and B, which is bent at the edges to bond the plates A and B (seaming), is widely used. (See Figure 21)

As a general embodiment of the above-mentioned binding means (seaming), a flange cover, a valve cover, and two sheet metals A and B are used as shown in FIGS.
Examples include binding means at the corners of the plates A and B when manufacturing a cover (box) such as a Y-type strainer cover and a motor cover.

The above-mentioned flange cover 20, valve cover 31, Y-type strainer cover 21, etc.
The outer cover (for example, a pipe in which the outer circumference of the outer pipe 24 is covered with the heat insulating material 25 and the racking cover 26) is fitted over a flange or a valve arranged in the conduit to cover them. Is to cover and cover the arranged motor,

The flange cover 20, the valve cover 31,
Initially, the Y-type strainer cover 21 etc. is provided with a cover half body such as a semi-cylindrical shape or a half-angle tube shape obtained by dividing the covers into two by binding two plates A and B,

A pair of cover halves are screwed together to fit the belly.
Alternatively, the flange cover 20, the valve cover 31, the Y-type strainer cover 21 and the like are manufactured by connecting with the sheath 27 and other connecting means.

Further, as described above, in addition to the structure in which a pair of cover halves are connected to each other, the motor cover 22 and the like have two parts.
It is manufactured only by binding the sheets A and B together.

Therefore, the use of the binding means for the two plates is as follows.
Any sheet metal molded product to which this binding means can be applied is completely arbitrary and various.

The characteristics of the binding means are as follows. First, the three-fold edge a of the plate A and the right-angled edge b of the plate B are bound in a substantially right-angled direction, and the binding is the three-fold edge a. Since the tip a ₂ of the tri-fold edge a is further bent at an inward right angle on the right-angled edge b of the plate B in which the tip b ₁ is fitted in the upper clear groove a ₁ , both plates A, The binding of B is performed very firmly,

Due to the binding state as described above, it is excellent in airtightness and watertightness (waterproofness),

Since the binding portion (corner portion e) is a quadruple plate (three-fold edge portion a + right-angled edge portion b), the portion serves as an aggregate or a column member, and the rigidity of the cover as a structural body. Is extremely large and cannot be easily crushed by external pressure or external impact.

[0013]

However, in the conventional implementation of the above-mentioned binding means (seaming) for two plates, as shown in FIG. 22, a plate A having three folded edges a formed by bending the edges into three folds,
The plate B having the right-angled edges b formed by bending the edges at right angles
With the tip b ₁ of the right-angled edge portion b of the plate inserted into the upper open groove a ₁ of the three-fold edge portion a of the plate A, it is placed on the anvil 29 or the like, and the thick iron plate 28 held by the operator is held. With the (tool), tap the tip a ₂ of the three-fold edge a at an inward right angle, in order from the chopstick,
It was crushed and tied together, all done by hand.

As a result, the following serious drawbacks and problems have occurred. That is, the tip a ₂ of the three-fold edge portion a is hit by the thick iron plate 28 from above or obliquely above to bend the edge at a right angle shockably and forcibly. Therefore, the bulge 30 is inevitably formed on the outer surface side of the three-fold edge portion a. Not only does this cause damage to the appearance, but the loosened seam between the three-fold edge a and the right-angled edge b reduces air-tightness and water-tightness. The finish is uneven and lacks uniformity.

Since the tip of the three-fold edge portion a is smashed by the thick iron plate 28 at an inward right angle, the surface has a struck mark and is uneven or scratched, resulting in poor appearance and damage to the coating or plating. It may peel off or deteriorate and cause rusting.

Since the work is manually performed by the worker, the efficiency is extremely low. Particularly, the sheet metal is strongly hit with an iron plate, which causes a great noise, which is not only bad for the hearing health of the worker but also an environmental pollution problem. There is.

Next, while the forming roll D is rotationally driven by the rotating means 11, the forming roll D is parallel along the corner C ₁ of the fixed mold C from one end of the corner c _{1 to} the other end. In the course of the parallel movement of the forming roll D, the three-fold edge portion a and the lower portion thereof which are engaged with the concave line c ₂ on the circumferential surface d ₂ of the small diameter portion of the rotational forming portion d and the lower portion thereof are fixed to the fixed mold C. While pressing against the vertical surface 2, at the same time, the tip a ₂ of the tri-fold edge a is pushed down on the horizontal plane 1 at an inward right angle on the lower surface d ₁ of the large diameter portion to form an edge bend, and then edge bend at the corner surface d _3. The corner portion e of the plate is formed into a target shape, and both plates A and B are bonded and shaped into a molded product E. Finally, the rod 13 of the air cylinder 13 is formed.
After extending and loosening a, the hook 12 of the rubber belt 12
a is removed from the rod 13a, and the molded product E is fixed to the fixed mold C.

The above operation is performed by a concrete molded product E, for example, a 1/4 cylinder and a polygonal cylinder (or a rectangular cylinder with the corners removed) like the valve cover 31 in FIG. Explaining the case of molded products with complex shapes,
(Refer to FIG. 6) First, the forming roll D is moved from the starting point to the parallel shaft holder 8
The parallel axis 9 moves to the start point, and then the left / right moving plate 4
The movement of 1 moves along the straight line portion, then the diagonal straight line portion of the corner portion moves by the combined movement of the left and right moving plates 41 and the front and rear moving plates 34, and the subsequent straight line portion ends by the movement of the front and rear moving plates 41. After moving to the separation point by the movement of the parallel shaft 9, the composite movement rotation of the forward / backward moving plate 34, the left / right moving plate 41, the parallel shaft 9, and the rotating shaft 7a returns and connects from the separation point to the start point. Finish dressing.

As described above, the means of the present invention forms a linear shape, a curved shape, an angular shape, an arc shape or a composite shape thereof by controlling the sequence of movement of the forming rolls for each molded product by a computer. It is designed to handle all shapes of the corners of the product.

[0050]

According to the present invention, the forming roll is formed by the movement of the parallel shaft of the parallel shaft holder, the rotation of the parallel shaft holder by the rotating shaft, the horizontal movement by the left and right moving plates and the front and back moving plates, and their combined movement rotation. Since it is designed so that it can be freely moved according to any shape of the corner part of the fixed mold (that is, the corner part of the molded product) to perform binding and shaping, it is conventionally possible for all workers to manually Since the tip of the three-fold edge was smashed at a right angle inward with a thick iron plate, it was possible to automate extremely rough, inaccurate, and inefficient work, and to achieve high speed, high efficiency, and high accuracy. Has a term effect.

The corner portion of the fixed mold is set according to the shape of the corner portion of the molded product such as the flange cover and the valve cover, and the means of the present invention is freely operated by a computer program or the like to move the molding roll to the corner portion. Since the control movement is performed along the shape of, the shape of the corner can be formed into any shape, such as a straight line, a circle, a curve, a square, or a combination thereof.

While pressing the three-fold edge portion on the circumferential surface of the small-diameter portion of the forming roll which rotates and moves, the tip of the three-fold edge portion is fixed on the lower surface of the large-diameter portion and the corner surface. Since the edge is bent at an inward right angle on the surface of the surface, unlike the conventional method of hitting and crushing with a thick iron plate at the tip, all edges are smoothly and smoothly formed by the contact pressure of the rotating surface. As a result, it can be done without hitting scratches, unevenness, coating, plating damage, etc., and the three-fold edge is pressed and held by the circumferential surface of the small diameter part and is flat-molded to be finished in a beautiful smooth surface. There is no possibility that the outer surface of the tri-fold edge will bulge outward and spoil the appearance as in the conventional case.

Since it is possible to make almost silent work at the same time with high productivity and high precision by automation, there is a problem of pollution in the workplace and environment due to the unprecedented noise of tapping work of metal comrades as in the past. There is no fear.
