Abstract

PURPOSE:To reduce a calking stage by providing the upper die and lower die equipped with a calking part and float preventing part respectively and arranging the upper die receiver and lower die receiver having a projecting shape as well. CONSTITUTION:A product pressing plate 4, linking shaft 5 and pressure spring 6 are assembled on the upper die 3 for a calking slide shaft 1 and a calking receiving shaft 7, pressure adjusting spring 8, calking float preventing plate 9 and pressing spring 10 are respectively assembled on the lower die 4. In the case of calking the front side, the floating prevention plate 9 is closely fitted to the plate 14 to be calked with the pressure of the spring 10 and a rivet 15 is calked. In the case of calking the back side, the upper die receiving base 12 and lower die receiving base 13 are changed from a recess to a projection and the calking is performed with the slide shaft 1 and receiving shaft. In this case, the pressing plate 4 presses the plate 14 with the pressure of a pressure spring 6 and the float preventing plate 9 closely fits the plate 14 and rivet 15. The calking stage is reduced because of the calking of both front and back being enabled.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a caulking machine for caulking a rivet or the like.

Prior Art A conventional crimping machine of this type had a structure as shown in FIG.

In other words, crimping is performed in one direction with the rivet-preventing sliding shaft 17 and the lower mold, using the rivet slide shaft 16 as the upper mold.

Problems to be Solved by the Invention However, with such a structure, when caulking is performed from the opposite direction, the product 18 must be reversed, and the above-mentioned process becomes necessary.

The present invention solves these conventional problems and provides a staking machine that can swam from both sides without reversing the product.

Means to Solve the ProblemsAnd the technical means of the present invention to solve the above problems is to provide the upper die with a caulking portion and a lifting prevention portion, and similarly provide the lower die with a caulking portion and a lifting prevention portion. It has a section.

For production The effect of this technical means is as follows.

That is, for front crimping, the upper die has a pair of crimping slide shafts and the lower die has a lifting prevention sliding shaft, and for back crimping, the upper die has a pair of lifting prevention sliding shafts and the lower die has a crimping slide shaft. Receive the movement from the upper mold and lower filJ.

Caulking is performed by changing the convex shape of the receiver. As a result, front and back crimping can be performed without reversing the product.

Embodiment 1 Below, one embodiment of the present invention will be described based on the accompanying drawings.

In FIG. 1, 1 is a crimping slide shaft, and 2 is a pressure adjustment spring for the crimping slide shaft 1, which is assembled into an upper mold 3. 4 is a product holding plate, and 6 is a connecting shaft of the product holding plate 4 which is interlocked with the product holding plate 6. Further, 6 is a pressure spring of the product holding plate 4. Above product holding plate 4. Connecting shaft 5. Pressure spring is upper mold 3
is incorporated into.

The crimping receiver 7 is a shaft, and the crimping receiver 8 is a pressure adjustment spring for the shaft 7. The crimping receiver 9 is a crimping lifting prevention plate that slides along the shaft 7, and is in close contact with the product by a crimping lifting prevention temporary holding spring 10.

The above caulking receiver is shaft 7. Pressure adjustment spring 8. Caulking lifting prevention plate 9. The presser spring 10 is assembled into the lower die 11.

Reference numeral 12 indicates an upper die holder and 13 indicates a lower die holder, which performs the vertical movement of crimping. Further, 14 is a disc-shaped plate to be caulked, and 15 is a rivet to be caulked.

The operation of the crimping machine configured as described above will be explained below.

From FIG. 1, when caulking the front side, the caulking slide shaft 1 and the caulking receiver are caulked by the shaft 7, but at that time, in order to prevent the caulking from floating, the caulking prevention plate 9 is pressed by the pressure of the caulking prevention presser spring 1Q. It comes into close contact with the disk-like plate 14 to be caulked, and is caulked with no gap in the rivet 16 to be caulked. The caulking prevention valve spring 1o is the product holding plate 4. The connecting shaft has a pressure greater than the weight of the 5° pressure spring.

Next, when crimping the back side, the upper die holder and the lower die holder 12 and 13 are switched from the concave portion to the convex portion. The switched diagram is shown in Figure 2. The caulking slide shaft 1 and the caulking receiver are shaft 7.
However, due to the pressure of the product presser plate pressure spring 6, the product presser plate 4 presses the disc-shaped plate 14 to be caulked,
The disk-shaped plate 14 to be caulked with the caulking lifting prevention plate 9 and the rivet 15 to be caulked are brought into close contact with each other, and caulking is performed.

Effects of the Invention As described above, according to the present invention, crimping can be performed on two sides and on the actual image side, and the number of crimping steps can be reduced.
