Specific embodiment
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The embodiment 1 of closed cavity parts of the invention, as shown in Figure 1 to 11, closed cavity parts include metal plate
Golden part 1, pinch plate 2 and outer buckle 3, sheet metal component 1 include the side plate 12 that the upward bending of base plate 14 and the left and right sides of base plate 14 is formed,
After the opposite bending in end of biside plate 12, still further below bending formed two later bent plate 13, pinch plate 2 by mortise structure fix dress
Fit on later bent plate 13, outer buckle 3 is the trench structure that Open Side Down, including trough floor and the groove positioned at trough floor both sides
Wall, the cell wall of outer buckle 3 is clamped at two later between bent plate 13, and the fastener of outer buckle 3 is on pinch plate 2.Mortise structure includes
The bayonet socket 11 opened up respectively in two relative plate faces on later bent plate 13 and the clamp set at the two ends of pinch plate 2 or so
21.Bayonet socket 11 is "T"-shaped passage wide at the top and narrow at the bottom, is made up of the tenon mouthful 111 and entrance 112 of connection setting up and down, entrance 112
To be arranged on the opening opened down at the later lower edge of bent plate 13.Clamp 21 includes the tenon plate being adapted with tenon mouthful 111
211, the outside of two tenon plates 211 is provided with two for baffle plate 212, and the width of baffle plate 212 is more than the width of tenon mouthful 111, with
Prevent tenon plate 211 from departing from from tenon mouthful 111, be provided with rebound 22 between two tenon plates 211, the width of rebound 22 be less than into
The width of mouth 112.Offered on the cell wall of outer buckle 3 for detaining the fixing groove 31 hung on pinch plate 2, fixing groove 31 includes shape
Draw-in groove into " L " shape passage enters in draw-in groove with ferry, rebound 22 is crossed along ferry is crossed, and realizes pinch plate 2 with outer buckle 3 upper
The upward block in lower section coordinates.Outer buckle 3 is filled in the breach that the two two relative plate faces for turning one's head bent plate are formed, and trough floor
Upper face with later bent plate is flushed, and Formation cross-section is square closed cavity parts.
The processing method of closed cavity parts is：The first step, using common Bending Mould by the left and right sides of base plate 14
Upward bending respectively, forms side plate 12, and now actual bending state is that the angle that side plate 12 is formed with base plate 14 is close to right angle
Obtuse angle, then by the opposite bending of biside plate 12, be bent into later bent plate 13 towards base plate still further below, form the metal plate with die cavity
Part 1.Second step, makes the rebound 22 of pinch plate 2 enter tenon mouthful 111 from the entrance 112 of the later bent plate 13 in left side, moves right
Pinch plate 2, the tenon plate 211 and 111 joggles of tenon mouthful for making the left end of pinch plate 2 coordinates, and then same operation makes the right-hand member of pinch plate 2
111 joggles of tenon mouthful of later bent plate 13 on tenon plate 211 and right side coordinate.I.e. the two ends of pinch plate 2 are by mortise structure point
It is not securely fitted on the later bent plate 13 of arranged on left and right sides.When both sides are after later bent plate 13 all carries out joggle with pinch plate 2,
By actual bending state（As shown in Figure 4）It is preferable bending state to correct（As shown in Figure 8）, make biside plate vertical with base plate.Metal plate
Golden part 1 makes later bent plate hold out against baffle plate due to the tension force that natural resiliency deformation is produced, it is ensured that pinch plate 2 will not fall off, and reach
Correct the purpose of External Shape.3rd step, breach of the left and right sides later between bent plate is inserted by outer buckle 3, wraps ferry
The rebound 22 of pinch plate 2 is covered, rebound 22 enters in draw-in groove along ferry is crossed so that outer buckle 3 is assemblied on pinch plate 2,
Form closed cavity parts.
In the embodiment 2 of inventive closure formula cavity parts, unlike embodiment 1, as shown in figure 12, metal plate
The bayonet socket 101 later on bent plate of part 10 is enclosuring structure, including entrance wide at the top and narrow at the bottom and tenon mouthful setting up and down, entrance
Width is provided with the gear edge moved up for block tenon plate 211, two gears more than the width of baffle plate 212 between entrance and tenon mouthful
Along the distance between more than rebound width, less than the width of tenon plate 211.
In the embodiment 3 of inventive closure formula cavity parts, and unlike the structure of embodiment 1, such as Figure 13 to Figure 14
Shown, the edge of the later bent plate of sheet metal component 100 is convexly equipped with clamp 102, and clamp 102 includes up-narrow and down-wide tenon setting up and down
Head plate and baffle plate, are symmetrically provided with two pairs of tenons being connected mouthful and entrance on pinch plate 20, two tenons mouthful are located at the outside of two entrances,
Width of the width of entrance more than baffle plate.
