Description
Technical Field
The utility model relates to the technical field of manufacturing of progressive dies of motor iron cores, in particular to a punching structure for preventing a product from being imprinted.
Background
In the field of manufacturing of existing progressive dies for motor iron cores, two holes with different sizes are required to be switched in the same position of some products. In actual production, in order to meet the requirements of customers on products, the production is convenient, and the working efficiency is improved, so that hole male dies with different sizes are switched in a manual plate drawing mode during punching of different holes, and different holes are punched. However, the product stamped by the method is often scrapped because the strip material is pressed due to the fact that the weight of the other large-hole male die is larger when the small-hole male die is switched, and the product is stamped.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a punching structure for preventing a product from being imprinted, which aims to overcome the defects and shortcomings of the prior art, and the large male die is hoisted by increasing the large male die and pulled by a spring on the hoisting, so that the large male die does not fall down and cannot be imprinted on a strip material when a small hole is punched, the rejection of the product due to imprinting is avoided, and the yield of the product is greatly improved.
In order to achieve the purpose, the utility model adopts the following technical scheme: the device comprises a small-hole male die, a large-hole male die, a drawing plate, a male die fixing plate, a male die base plate and an upper die base; a male die base plate is arranged below the upper die base, a male die fixing plate is arranged at the lower part of the male die base plate, a small-hole male die and a large-hole male die are both arranged in the male die fixing plate, and a drawing plate is movably arranged between the male die base plate and the male die fixing plate in a penetrating way and is fixed with the male die fixing plate; it also comprises a convex die hanging pipe; the male die hanging tube is movably arranged in the upper die base in a penetrating mode, and the lower end of the male die hanging tube is connected with the upper end of the large-hole male die.
Preferably, a spring is arranged between the male die hanging tube and the hole wall of the through hole of the upper die base, and the spring is sleeved on the male die hanging tube.
Preferably, the upper end of the spring abuts against the lower surface of the end cap at the top end of the male die hanging tube, and the lower end of the spring abuts against the bottom wall of the through hole of the upper die holder.
Compared with the prior art, the utility model has the beneficial effects that: the utility model provides a punching structure for preventing a product from being imprinted, which is characterized in that a large male die is hoisted by increasing the number of the large male die, and a spring on the hoist is used for pulling the large male die, so that the large male die does not drop and cannot be imprinted on a strip material when a small hole is punched, the rejection of the product due to imprinting is avoided, and the yield of the product is greatly improved.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Description of reference numerals:
the device comprises a strip material 1, a small-hole male die 2, a large-hole male die 3, a drawing plate 4, a male die fixing plate 5, a male die base plate 6, an upper die base 7, a male die hanging pipe 8 and a spring 9.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings, and the preferred embodiments in the description are only examples, and all other embodiments obtained by those skilled in the art without any inventive work belong to the protection scope of the present invention.
As shown in fig. 1, the following technical solutions are adopted in the present embodiment: the device comprises a small-hole male die 2, a large-hole male die 3, a pulling plate 4, a male die fixing plate 5, a male die base plate 6 and an upper die base 7; a punch backing plate 6 is arranged below the upper die holder 7, a punch fixing plate 5 is arranged at the lower part of the punch backing plate 6, the small-hole punch 2 and the large-hole punch 3 are both arranged in the punch fixing plate 5, and the drawing plate 4 is movably arranged between the punch backing plate 6 and the punch fixing plate 5 and fixed with the punch fixing plate 5 in a penetrating manner; it also comprises a male die hanging tube 8; the male die hanging tube 8 is movably arranged in the upper die base 7 in a penetrating way, and the lower end of the male die hanging tube is connected with the upper end of the large-hole male die 3; a spring 9 is arranged between the punch hole wall of the male die hanging tube 8 and the punch hole wall of the upper die base 7, the spring 9 is sleeved on the male die hanging tube 8, the upper end of the spring 9 abuts against the lower surface of the end cap at the top end of the male die hanging tube 8, and the lower end of the spring 9 abuts against the punch hole bottom wall of the upper die base 7.
When using this structure of punching a hole, place strip 1 in the below position of upper die base 7, when needs switch the punching press aperture, utilize spring 9 to hold terrace die hanging pipe 8 to hang macroporous terrace die 3 through terrace die hanging pipe 8, be unlikely to drop on strip 1, thereby effectively avoid macroporous terrace die 3 to drop the impression on strip 1.
Compared with the prior art, the beneficial effects of the embodiment are as follows: this embodiment provides a structure of punching a hole that prevents to have impress on product, through increasing big terrace die hoist and mount, utilizes the spring of hoist and mount to hold big terrace die for when dashing the aperture, big terrace die does not take place the tenesmus, can not press the strip material, avoids appearing the impression on the product and scrapping, very big improvement the yields of product.
