Description
Technical field
The utility model belongs to the Stamping Die Technology field, relates to the punch of extending in a kind of air-conditioner fin die, specifically a kind of quick detachable punch structure of extending.
Background technology
At present, traditional pipe type heat exchanger is the main heat exchange form of domestic air conditioning, central air-conditioning, car air-conditioner and fan coil.Air-conditioner fin is the vitals in the pipe type heat exchanger, and air-conditioner fin generally adopts the air-conditioner fin die punching press to make, and its production process generally comprises and extends, punching, shutter, flange, abnormal shape are cut, cut on the limit, correcting, rip cutting, feeding and crosscut.The operation of extending is the preform operation on the air-conditioning mould, and the operation of extending relies on the submodule of extending to finish, and the punch of extending is the critical piece in the punch of extending.For guaranteeing product quality, the punch of extending just need carry out polishing in use for some time, often needs dismounting.Traditional punch of extending is installed on the lower bolster by fixture, fixture adopts the punch retainer of monoblock, offer several nibs on the punch retainer, the punch of extending is housed in each nib, nib comprises first sector hole and second sector holes coaxial but that internal diameter is different, the first sector hole size is less than the second sector hole size, the die body of punch of extending is corresponding with first sector hole, the mould tail of punch of extending is corresponding with second sector hole, and the punch of extending can move axially in nib can't deviate from nib.During the punch of extending dismounting, need earlier punch retainer to be taken apart, and then in punch retainer, extract the punch of extending.Even only need take out the punch of extending, also need punch retainer is all pulled down, and the volume weight of punch retainer is general bigger, dismounting is wasted time and energy, thereby influences production efficiency.And regular dismantle punch retainer and can have a strong impact on fixed precision, cause product quality not high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple and reasonable, and convenient disassembly is the quick detachable punch structure of extending efficiently.
The technical scheme that provides according to the utility model: a kind of quick detachable punch structure of extending, comprise the punch of extending, fixture and lower bolster, the punch of extending is installed on the lower bolster by fixture, it is characterized in that: described fixture comprises punch cover plate and punch retainer, punch retainer is placed on the lower bolster and with lower bolster and is connected, and the punch cover plate is placed on the punch retainer and with punch retainer and is connected; Offer cover plate nib and fixed head nib on punch cover plate and the punch retainer respectively, cover plate nib and fixed head nib are corresponding one by one, and the cover plate mold hole dimension is less than the fixed head mold hole dimension; The punch of extending is contained in cover plate nib and the fixed head nib, and the die body of the punch of extending is corresponding with the cover plate nib, and the mould tail of the punch of extending is corresponding with the fixed head nib, and the punch of extending can move axially in cover plate nib and fixed head nib.
As further improvement of the utility model, between described punch retainer and the lower bolster, utilize screw to be connected between punch cover plate and the punch retainer.
The utility model compared with prior art, advantage is: the mounting means that has changed the punch of extending, when punch is extended in dismounting, can take out the punch of extending as long as pull down the punch cover plate, more convenient, improve production efficiency greatly, overcome the defective that punch retainer regular dismounting influences fixed precision simultaneously, helped guaranteeing product quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A portion enlarged diagram among Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2: the utility model mainly comprises parts such as the punch 2 of extending, punch cover plate 3, punch retainer 4 and lower bolster 5, punch retainer 4 is placed on the lower bolster 5 and utilizes screw to be connected with lower bolster 5, and punch cover plate 3 is placed on the punch retainer 4 and utilizes screw to be connected with punch retainer 4; Offer cover plate nib 3a and fixed head nib 4a on punch cover plate 3 and the punch retainer 4 respectively, cover plate nib 3a and fixed head nib 4a are corresponding one by one, and cover plate nib 3a size is less than fixed head nib 4a size; The punch 2 of extending is contained in cover plate nib 3a and the fixed head nib 4a, and the die body 2a of the punch 2 of extending is corresponding with cover plate nib 3a, and the mould tail 2b of the punch 2 of extending is corresponding with fixed head nib 4a; The punch 2 of extending can move axially in cover plate nib 3a and fixed head nib 4a.
As shown in Figure 1 and Figure 2, the below of punch retainer 4 is provided with declivity and carves 6, declivity is carved 6 and is contacted with the mould tail 2a end of the punch 2 of extending, declivity is carved 6 and can be moved up and down, declivity is carved 6 and is promoted to extend punch 2 when moving up, the punch 2 of extending relies on the guiding of punch cover plate 3 and punch retainer 4 to move up, and carries out punching operation.The top of punch cover plate 3 is provided with stripper 1, and the billot that stripper 1 is used for being enclosed within behind the stamping-out on the punch 2 of extending unloads.When the punch 2 of extending needs dismounting, as long as earlier stripper 1 is removed, then punch cover plate 3 is taken apart from punch retainer 4, the punch 2 of extending that can directly will need to take out is extracted from punch retainer 4, need not punch retainer 4 is pulled down, change more conveniently, improved production efficiency greatly, having overcome punch retainer 4 regular dismountings simultaneously influences the defective of fixed precision, helps guaranteeing product quality.
