Abstract
The utility model belongs to the technical field of assembly of cold-punching mold of thick plates and particularly relates to a paired-gap structure for assembling thick plates with punched round holes. The paired-gap structure comprises a round punch, wherein the round punch is provided with a punch edge part. The paired-gap structure is characterized in that a punch paired-gap part is arranged on the round punch at one side of the punch edge part; the diameter of the processing size of the punch paired-gap part is the sum of the diameter of each punched hole and the gap of two punching edges, and the tolerance range is -0.01-0.03mm. The paired-gap structure has the advantages that the processing is simple, and the operation is convenient; uniform gaps of the mold are ensured by changing the shape of the common punch and the assembling process, the cost is low and the popularization and the application are convenient.
Description
(1) technical field
The utility model relates to a kind of slab and rushes circular port assembling to interstitial structure, belongs to slab cold-punching mould mounting technology field.
(2) background technology
When punch die assembles, the stamping-out more complicated of slab, gap is larger, the even bad assurance in gap, the inhomogeneous meeting in gap makes a big impact to the size of product and quality.Home and abroad slab cold-punching mould punching is at present equipped with varied, as detected with clearance gauge, and grating detection etc., but clearance gauge detection is inconvenient for circular port, and grating detects and is subject to the shortcomings such as site condition restriction.
(3) summary of the invention
The utility model is in order to make up the defect of prior art, provides that a kind of processing is simple, cost is low, and easy to operate slab rushes circular port assembling to interstitial structure.
The utility model is achieved by the following technical solution:
A kind of slab rushes circular port assembling to interstitial structure, comprise round punch, round punch is provided with punch head blade notch portion, it is characterized in that: the round punch of described punch head blade notch portion one side is provided with drift to gap portion, drift to gap portion processing dimension diameter be the diameter of institute's punching and the bilateral gap of stamping-out and, the margin of tolerance is at-0.01--0.03mm.
The beneficial effects of the utility model are: processing is simple, easy to operate; By changing the shape of common drift and the technique of assembling, guarantee that the gap of mould is even, cost is low, easy to utilize.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 3 is assembly structure schematic diagram.
In figure: 1, round punch; 2, punch head blade notch portion; 3, drift is to gap portion; 4, die hole; 5, trip bolt; 6, shop bolt.
The specific embodiment
Accompanying drawing is specific embodiment of the utility model.
The utility model slab as shown in Figure 1 rushes circular port assembling to interstitial structure, comprise round punch 1, round punch 1 is provided with punch head blade notch portion 2, the round punch 1 of described punch head blade notch portion 2 one sides is provided with drift to gap portion 3, drift to gap portion 3 processing dimension diameters be the diameter of institute's punching and the bilateral gap of stamping-out and, the margin of tolerance is at-0.01--0.03mm.
As shown in Figure 2 and Figure 3, during assembling, upper and lower mould merges, and trip bolt 5 is unclamped, and adjusts drift is stretched in die hole 4 gap portion 3, and then fastening upper and lower mould screw, after completing, reinstalls shop bolt 6.
Claims (1)
