As shown in fig. 4, 5, 7, 8, 9 and 10, the press apparatus of the present invention includes a material supply unit 300 that discontinuously supplies the work material 2 at intervals of the longitudinal position control holes 3 and the width position control holes 4. The material supply unit 300 includes: a first supply unit 310 configured to discontinuously supply the work sheet 2 to the preform unit 100; a connecting part 320 which is located between the preform part 100 and a pattern forming part 400 described later and connects the opposite uneven part 2a of the processed plate material 2' which is formed first and the uneven part (2b) of the processed plate material 2 ″ which is formed later; the second supply section 330 discontinuously supplies the work pieces 2 connected by the connection section 320 from the preforming section 100 to the pattern forming section 400.
Here, the first supply part 310 includes: an unwinding roll (311) for winding the sheet material 2 into a roll shape; the supply roller 312 discontinuously supplies the work sheet material 2 wound around the unwinding roller 311.
At least one of the unwinding roller 311 and the feeding roller 312 is discontinuously fed with the work sheet material 2 by a stepping motor (not shown) that rotates at an angle corresponding to the interval p of the longitudinal position control holes 3 formed in the work sheet material 2.

Specifically, the post-forming work piece 2 ″ is positioned slightly above the pre-forming work piece 2' by the elastic pin 322. When the pressing operation is performed in this state, the elastic pin 322 is pressed to lower the post-forming work piece 2 ″, and in this process, the uneven portions 2b and the opposing uneven portions 2a of the post-forming work piece 2 ″, and the pre-forming work piece 2 'intersect with each other and are joined to each other, whereby the two work pieces 2', 2 ″ are joined to each other.
The second supply unit 330 is disposed between the preform unit 100 and the pattern forming unit 400, and includes: a first fixing block 331 fixed to the preform 100; a second fixing block 332 fixed to the pattern forming part 400; a rail 333 connecting the first fixed block 331 and the second fixed block 332; a conveying block 334 disposed between the first and second fixed blocks 331 and 332 and movable along a rail 333; the transfer cylinder 335 controls the transfer of the transfer block 334 in a state of being disposed in one of the first fixed block 331 and the second fixed block 332.
The conveying block 334 includes a clamping portion 334a for clamping the plate material 2 to be processed. The clamping portion 334a includes: a variable clamp 334b that moves up and down the conveyance block 334 by an up-down cylinder 334 c; when the work sheet 2 is introduced between the fixed nip portion 334d and the variable nip portion 334b, the fixed nip portion 334d provided above the conveying block 334 raises by the raising/lowering cylinder 334c to approach the fixed nip portion 334d, thereby nipping the work sheet 2 therebetween. In this state, when the transport block 334 moves forward from the first fixed block 331 to the second fixed block 332, the work sheet 2 is transported to the pattern forming section 400, and conversely, when the transport block 334 moves backward from the second fixed block 332 to the first fixed block 331, the work sheet 2 is prevented from moving backward because the work sheet 2 is not sandwiched.
As shown in fig. 5 and 10, the press apparatus of the present invention includes a pattern forming section 400 including a plurality of pattern press punches (pattern punches) 410, and the pattern press punches 410 are provided in the press machine 10 to form a pattern on the work sheet 2 supplied from the material supply section 300.
The pattern forming portion 400 forms a pattern of a desired shape by pressing, cutting, bending, or the like, the work sheet 2 by the interaction between the die 21 of the upper die 20 located in the pattern forming portion region and the pattern pressing punch 410 provided in the lower die 30.
Here, the pattern-pressing punches 410 are configured by kinds so as to be able to press and form a plurality of kinds of inner bands as shown in fig. 1 to 3, and the pattern-pressing punches 410 are individually controlled by a driving cylinder 420 so as to press and form a plurality of kinds of patterns.
The driving cylinder 420 is provided in the lower die 30 of the pattern forming part 400, an operation hole 32 is formed in the lower die 30, the operation hole 32 communicates with a punch hole 31(punch hole) in which the pattern punch 410 is provided, a cylinder rod 421 (cylinder rod) of the driving cylinder 420 is provided in the operation hole 32 to be movable forward and backward, a pressing part 422 is provided at a tip of the cylinder rod 421, and an inner end portion of the pattern punch 410 is forcibly pressed by the pressing part 422 when the cylinder rod 421 moves forward, so that the pattern punch 410 protrudes from the punch hole 31.
At this time, the pressing portion 422 includes a lower end surface 422a, an upper end surface 422b, and an inclined guide surface 422c connecting the both end surfaces. If the bottom end of the pattern-pressing punch 410 is supported by the lower end surface 422a, the pattern-pressing punch cannot protrude from the punch hole 31, and therefore cannot be used; when the bottom end of the pattern-pressing punch 410 is supported by the upper end surface 422b, the pattern-pressing punch protrudes from the punch hole 31, and thus becomes usable.
Here, the guide surface 422c functions to smoothly move the support surface at the bottom end of the pattern punch 410 when moving from the lower end surface 422a to the upper end surface 422 b.
As shown in fig. 12, the press apparatus according to the present invention includes a control unit 500, and the control unit 500 controls the driving of the material supply unit 300 and the pattern forming unit 400 based on the positions of the holes 3 and 4 detected by the hole detection unit 200 and a molding program selected from molding programs of molding types input in advance.
The control unit 500 receives feedback of detection data of the positions of the longitudinal direction position control hole 3 and the width direction position control hole 4 detected by the first hole detecting unit 210 and the second hole detecting unit 220, and controls the driving of the material supplying unit 300 based on the feedback data.
Further, since the control unit 500 stores the molding programs for the respective models of the inner band 1 in advance, the control unit drives the molding programs based on the input signal input from the input unit 600. At this time, the control section 500 can form a desired pattern by selectively driving the driving cylinders 420 of the pattern-pressing punches 410 for controlling the pattern forming section 400, and controlling what pattern-pressing punches 410 are used and what pattern-pressing punches 410 are not used.
In addition, as shown in fig. 13, the press apparatus according to the present invention further includes a lubricant oil adding portion 700 for adding lubricant oil to the supply roller 312.
The lubricating oil filler 700 includes: a lubricating oil tank 710 that stores lubricating oil; and a lubricant nozzle 720 for injecting lubricant to the supply roller 312 in a state of being supported by the lubricant tank 710. Such a lubricating oil adding portion 700 serves to reduce friction force and improve operability when the work sheet 2 is pressed.
As shown in fig. 14, the press apparatus according to the present invention preferably further includes a conveying unit 800, and the conveying unit 800 conveys the inner strip 1, which has been pattern-formed by the pattern forming unit 400, by a conveying unit 900 such as a conveyor belt.
The following describes a press process of the press apparatus of the present invention with reference to fig. 5 and 6.
First, when the operator selects one of the molding programs for each model of the inner band 1 through the input unit 600, the input data input from the input unit 600 is transmitted to the control unit 500.
The controller 500 controls the driving of the first and second feeders 310 and 320 of the material feeder 300 based on the transmitted data so that the work material 2 is fed by a distance corresponding to the predetermined feeding interval P each time.
At this time, the sheet material 2 to be processed fed from the first feeding section 310 to the preforming section 100 is punched with the longitudinal position control hole 3 by the first pierce punch 111, and then the sheet material is punched with the width position control hole 4 by the second pierce punch 112.
Thereafter, both side portions of the workpiece plate 2 where the position control holes are formed are cut into a concave-convex shape by the side cutting shear punch 121, and then the length thereof is cut by the length cutting shear punch 125. Thus, the work sheet 2 has a substantially rectangular sheet shape.
The rectangular workpiece plate 2 is connected to the previously formed workpiece plate 2' which has entered first, via the connecting portion 320. That is, when the work piece 2 ″ to be formed later is positioned on the elastic pin 322, it is aligned with the work piece 2' to be formed earlier. The processed plate 2 ″ formed later is only slightly above the processed plate 2' formed earlier.
When the pressing operation is performed in this state, the post-formed work piece 2 ″ and the elastic pin 322 are pressed to align the height of the post-formed work piece 2 ″ with the height of the pre-formed work piece 2 ', so that the uneven portion 2b of the post-formed work piece 2 ″ and the opposing uneven portion 2a of the pre-formed work piece 2' are engaged with each other and the two work pieces are joined to each other.
The sheet material 2 to be processed thus joined is conveyed by the second supply portion 330 controlled by the control portion 500 to the pattern forming portion 400 by the distance of the position control holes 4 in the width direction.
The pattern molding part 400 is installed as follows: each driving cylinder 420 is selectively activated according to a molding program input in advance, and only a pattern-pressing punch selected from the plurality of pattern-pressing punches 410 is used. In this state, the plate material 2 to be processed, which is conveyed to the pattern forming section 400, is pressed, so that a desired pattern can be formed.
On the other hand, when a pattern needs to be changed after a certain pattern is formed, the operator inputs a program of the changed pattern to the input unit 600. The program inputted to the input unit 600 is transferred to the control unit 500, and the material supply unit 300 and the pattern forming unit 400 are controlled according to the changed program, so that inner bands of different types can be continuously press-formed.
The embodiments of the present invention described above are disclosed for illustrative purposes, and various modifications, alterations, and additions can be made by those skilled in the art within the spirit and scope of the present invention as long as they have general knowledge about the present invention, and these modifications, alterations, and additions should be construed as falling within the scope of the claims below.
