Abstract
The utility model provides a side trimming die, which comprises a driver, a slide block, a punch and a lower die, wherein the driver is connected with the punch through the slide block, and the lower die is positioned below the punch and is deviated to one side of the punch; and the other side of the punch is also fixedly provided with a guide stop block which is resisted against the punch by the other side of the punch. The utility model discloses a side deburring mould is through increasing a reverse yawing force at the drift side to guarantee that the drift does not incline, thereby guaranteed the deburring yield of waiter.
Description
Technical Field
The utility model relates to a mould structure, concretely relates to side deburring mould.
Background
The side trimming die means that an included angle is formed between the trimming or punching angle and the stamping direction. As shown in fig. 1, the side trimming die includes a driver 1 ', a slider 2 ', a punch 3 ' (also called a male die), and a lower die 4 ' (also called a female die), the lower die 4 ' is disposed in a lower die frame 42 ', the driver 1 ' is connected to the punch 3 ' through the slider 2 ', and the lower die 4 ' is located below the punch 3 '; during trimming, as shown in fig. 2, a workpiece (not shown, the shape and structure of which can refer to the lower die 4 ') is located above the lower die, and when the punch 3' is driven by the driver 1 'to press down, the punch 3' and the lower die 4 'are located above and below the workpiece, and one left is the other right, so that the stress condition of the punch 3' and the lower die 4 'is similar to that of a scissors, and therefore, under the condition of a larger stress, the punch 3' is subjected to a larger lateral force to generate an inclination phenomenon, so that burrs are generated during trimming, and a product is poor.
Disclosure of Invention
The to-be-solved technical problem of the utility model lies in providing a side deburring mould through increasing a reverse yawing force at the drift side to guarantee that the drift does not incline, thereby guaranteed more waited's deburring yield.
The utility model discloses a realize like this: a side trimming die comprising a driver, a slider, a punch, and a lower die, said driver being connected to said punch through said slider, said lower die being located below said punch and biased to one side of said punch and applying a side force F1 to said punch; and the other side of the punch is fixedly provided with a positive guide stop which is resisted against the punch by the other side of the punch and applies another lateral force F2 to the punch, and the lateral force F2 is equal to the lateral force F1 in magnitude and opposite in direction.
According to the utility model discloses an embodiment, lead positive dog includes a baffle and fixing base, the fixing base is fixed in on the lower moulding frame, the baffle is fixed in the fixing base towards a side of drift, and hardness is less than the hardness of drift.
According to the utility model discloses an embodiment, the baffle is cast iron self-lubricating baffle, and the planting has the graphite grain above this kind of baffle, can be softer, consequently can not hinder the drift.
The utility model has the advantages that: the utility model discloses set firmly one at the opposite side of drift and lead positive dog, so, can receive a great yawing force and take place the slope phenomenon when the drift, lead positive dog and just can apply reverse yawing force from the opposite side of drift, two opposite direction's yawing force offsets the back, can prevent effectively that the drift from taking place the slope phenomenon, has improved the yield of product greatly.

Detailed Description
Referring to fig. 3 and 4, the side trimming die of the present invention includes a driver 1, a slider 2, a punch 3 and a lower die 4, wherein the lower die 4 is fixed on a lower die frame 42, the driver 1 is connected to the punch 3 through the slider 2, the lower die 4 is located below the punch 3 and is biased to one side of the punch 3, and a lateral force F1 is applied to the punch; and a positive guide stop 5 is fixedly arranged on the other side of the punch 3, the positive guide stop 5 is abutted against the punch 3 by the other side of the punch 3 and applies another lateral force F2 to the punch, and the lateral force F2 is equal to the lateral force F1 in opposite directions, so that the lateral force F1 applied to the punch 3 by the lower die 4 is counteracted.
In the preferred embodiment of the present invention, the positive stop 5 comprises a guide plate 51 and a fixing seat 52, the fixing seat 52 is fixed on the lower mold frame 42, and the guide plate 51 is fixed on a side of the fixing seat 52 facing the punch 3.
In order to protect the punch 3, the hardness of the guide plate 51 should be lower than that of the punch 3 so as to prevent the punch 3 from being scratched, for example, the guide plate 51 can be a cast iron self-lubricating guide plate, and graphite particles are planted on the guide plate 51 and are relatively soft, so that the punch 3 is not damaged, the service life of the punch 3 is prolonged, and the yield of products is ensured.
During trimming, as shown in fig. 5, a workpiece (not shown, the shape and structure of which can refer to the lower die 4 ') is located above the lower die, and when the punch 3' is driven by the driver 1 'to press down, the punch 3' and the lower die 4 'are located above and below the workpiece, and one left is the other right, so that the stress condition of the punch 3' and the lower die 4 'is similar to that of a scissors, and therefore, under the condition of a larger stress, the punch 3' is subjected to a larger lateral force to generate an inclination phenomenon, so that burrs are generated during trimming, and a product is poor.
The utility model has the advantages that: the utility model discloses set firmly one at the opposite side of drift and lead positive dog, so, can receive a great yawing force and take place the slope phenomenon when the drift, lead positive dog and just can apply reverse yawing force from the opposite side of drift, two opposite direction's yawing force offsets the back, can prevent effectively that the drift from taking place the slope phenomenon, has improved the yield of product greatly.
Although specific embodiments of the present invention have been described, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the claims appended hereto.
