Abstract
The utility model discloses an extraction tool for retaining block of slitting knife applicable to die for producing air-condition fin. The extraction tool herein comprises a screw rod which is fastened to the retaining block of slitting knife, wherein the screw rod is provided with a hit-endurable member which is also provided with a nylon block thereabove, the hit-endurable member and the nylon block being both provided with a retaining aperture and being orderly fixed to the screw rod by a retaining screw through the screw rod, an impact sleeve sleeving on the screw rod and below the hit-endurable member. The extraction tool for retaining block of slitting block adopts the impact sleeve to perform up and down repetitive impact on the hit-endurable member so as to enable the retaining block of slitting block to escape from a retaining base. The utility model has the advantages of simple structure, easy realization, convenient dismounting and mounting between the retaining block of slitting knife and the retaining base of slitting knife, and higher working efficiency.
Description
Technical field
The utility model relates to a kind of mould structure, particularly relates to a kind of longitudinal knife fixed block driver-extractor that is used for air-conditioner fin die.
Background technology
As everyone knows, air-conditioner fin die is a kind of high-accuracy cold punching progressive die of special production air-conditioner fin, air-conditioner fin is exactly the fin that is used for heat exchange in air-conditioning, most fin material is aluminium and copper, at present, in the existing air-conditioner fin die, the longitudinal knife fixed block on it is a close-fitting with cooperating of longitudinal knife holder, and dismounting is difficulty quite; And on punch press, trick is inconvenient movable, and dismounting is difficulty more.
The utility model content
The purpose of this utility model is to provide a kind of longitudinal knife fixed block driver-extractor, and it has simple in structure, is easy to realize; Longitudinal knife fixed block and the easy-to-dismount characteristics of longitudinal knife holder.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of longitudinal knife fixed block driver-extractor, it comprises the screw rod that is fixed on the longitudinal knife fixed block, and described screw rod is provided with the anti-part that hits, and the described anti-part that hits is fixed on the screw rod, is provided with ram in the anti-below of hitting part on the described screw rod.
Described ram is the bump sleeve that is sheathed on the screw rod.
The described anti-top of hitting part also is provided with nylon block, and described anti-hitting all offers fixing hole on part and the nylon block, and with the anti-part that hits, nylon block is fixed on the screw rod fixed screw successively by fixing hole.
The beneficial effects of the utility model are, described longitudinal knife fixed block driver-extractor is provided with the anti-part that hits on the screw rod that is fixed in the longitudinal knife fixed block, and be arranged with the bump sleeve in the anti-below of hitting part on the screw rod, clash into the anti-part that hits up and down repeatedly with the bump sleeve, thereby the longitudinal knife fixed block is broken away from from the longitudinal knife holder, not only simple in structure, be easy to realize; And greatly facilitate the dismounting assembling of longitudinal knife fixed block and longitudinal knife holder, increase work efficiency.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the profile of the utility model longitudinal knife fixed block driver-extractor,
Fig. 2 is that the utility model longitudinal knife fixed block driver-extractor is assemblied in the profile on the longitudinal knife fixed block.
Among the figure:
1, screw rod; 2, bump sleeve; 3, the anti-part that hits; 4, nylon block; 5, fixing hole; 6, fixed screw; 7, longitudinal knife holder; 8, longitudinal knife fixed block; 9, rip cutting cutter.
The specific embodiment
Please refer to Fig. 1 to shown in Figure 2, Fig. 1 is the profile of the utility model longitudinal knife fixed block driver-extractor, and Fig. 2 is that the utility model longitudinal knife fixed block driver-extractor is assemblied in the profile on the longitudinal knife fixed block.
In present embodiment, a kind of longitudinal knife fixed block driver-extractor, it comprises a screw rod 1, described screw rod 1 is fixed on the longitudinal knife fixed block 8, be fixed with rip cutting cutter 9 on the described longitudinal knife fixed block 8, and described longitudinal knife fixed block 8 close-fitting longitudinal knife holders 7 are provided with, and described screw rod 1 is provided with the anti-part 3 that hits, the described anti-top of hitting part 3 also is provided with nylon block 4, describedly anti-ly hit on part 3 and the nylon block 4 all that correspondence offers fixing hole 5, utilize fixed screw 6 by fixing hole 5 with the anti-part 3 that hits, nylon block 4 is fixed on the screw rod 1 successively, and be provided with bump sleeve 2 in the anti-below of hitting part 3 on the described screw rod 1, described bump sleeve 2 is sheathed on screw rod 1, can move along screw rod 1 easy on and off.
During dismounting longitudinal knife fixed block 8, operation bump sleeve 2 makes it clash into the anti-part 3 that hits repeatedly, utilize impact that longitudinal knife fixed block 8 is broken away from from longitudinal knife holder 7, thereby dismantle longitudinal knife fixed block 8 quickly and easily, not only simple in structure, and improved the removal efficiency of dismantling longitudinal knife fixed block 8.
