Description
Technical field
The present invention relates to a kind of punching dies, belong to processing mold technical field.
Background technology
Mold is using extremely wide and important technique in industrial production as one kind of the efficient tool of production
Equipment, type include piercing die, blanking die, bending die, Drawing Die etc..Wherein punching die is relatively conventional, utilization in mold
More one kind is punched on parts according to actual needs after the completion of parts production, in order to which subsequent installation is grasped
Make.Can the quality of punching quality mainly depends on whether the positioning with punching die is accurate, effectively stablize work in punch process
Part position makes punching beat at the desired position without deviating.
Invention content
Purpose：In order to overcome the deficiencies in the prior art, the present invention provides a kind of punching die.
Technical solution：In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of punching die, including cope plate, lower template, punch, piercing punch and pressing device, the cope plate both sides are equipped with
Guide post, lower template both sides are equipped with guide sleeve, and the punch is fixed by fixed block and cope plate, and piercing punch is equipped with duct, with
Punch size matches；The pressing device includes elastomeric element and holding pad, and the holding pad is equipped with through-hole, with piercing punch
On pore passage structure position it is corresponding up and down；One end of the elastomeric element is fixedly connected with fixed block, and the other end is fixedly connected with binder
Plate.
Further, the fixed block is bolted with cope plate.
Further, ladder hole is equipped among the fixed block, the punch has T fonts head, the T fonts of punch
Head is matched with the ladder hole of fixed block.
Further, the part of the ladder hole of the punch insertion fixed block is coated with rubber washer.
Further, the elastomeric element includes connecting rod and spring, and spring is nested in connecting rod；The two of the spring
End is separately fixed on fixed block and holding pad, and connecting rod one end is fixed on holding pad, and fixed block is equipped with duct, connecting rod
One end far from holding pad is inserted into duct, and can be moved up and down along duct.
Further, there are two the elastomeric element is set, two elastomeric elements are located along the same line with punch.
Advantageous effect：A kind of punching die provided by the invention, simple in structure, easy to operate, when punch operation, is effectively solid
Determine workpiece, avoid deviating there is a situation where punch position；Punch is detachably connected with template, and easy maintenance and replacement is saved into
This.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the details enlarged drawing of elastomeric element in Fig. 1；
Fig. 3 is the structure diagram of fixed block and punch.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of punching die, including cope plate 1, lower template 2, punch 3, piercing punch 4 and pressing device,
1 both sides of cope plate are equipped with guide post 11, and 2 both sides of lower template are equipped with guide sleeve 21, and guide post 11 is embedded in guide sleeve 21, and can be in guide sleeve
Interior slip.The punch 3 is fixed by fixed block 5 and cope plate 1, and fixed block 5 is fixed by bolt 51 and cope plate 1, convenient
It installs and uninstalls；Ladder hole is equipped among the fixed block 5, the punch 3 has T fonts head, the T font heads of punch 3
Portion is matched with the ladder hole of fixed block 5, as shown in Figure 3；The part that punch 3 is inserted into the ladder hole of fixed block 5 is coated with rubber
Leather washer prevents punch play in fixed block, influences punching stability.The combination type of attachment of punch and fixed block facilitates dimension
It repaiies and replaces, when mold usage time is grown, and abrasion or damage occur for punch, need to only remove fixed block, replace punch,
It is easy to operate and save production cost.The piercing punch 4 is equipped with duct 40, is matched with punch size.
The pressing device includes elastomeric element 6 and holding pad 7, and the holding pad 7 is equipped on through-hole, with piercing punch
Pore passage structure position it is corresponding up and down；One end of the elastomeric element 6 is fixedly connected with fixed block 5, and the other end is fixedly connected with binder
Plate 7.The elastomeric element 6 includes connecting rod 61 and spring 62, and spring 62 is nested in connecting rod 61, refering to Fig. 2；The spring
62 both ends are separately fixed on fixed block 5 and holding pad 7, and one end of connecting rod 61 is fixed on holding pad 7；On fixed block 5
Equipped with duct, the one end of connecting rod 61 far from holding pad can be inserted into duct, and can be moved up and down along duct.The elastomeric element
6 set there are two, two elastomeric elements are located along the same line with punch, make pressing device when pressing to workpiece, workpiece both sides
Stress balance compresses better.
The course of work of the present invention is as follows：
Workpiece to be punctured is prevented on piercing punch, the position that need to be punched is corresponding with the duct on piercing punch；Upper diaphragm plate
It moves down, pressing device is moved down also with upper diaphragm plate, until holding pad contacts workpiece, spring is in a state of nature at this time；On
Template continues to move down, and spring starts to compress, and downward pressure is imposed to workpiece, so as to be fixed workpiece, while punch
Workpiece is punched.After punching, cope plate restores to the original state downwards.
The above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
