Description
Technical Field
The utility model belongs to the technical field of stamping die technique and specifically relates to a cylinder slide wedge structure of guide pillar guide pin bushing direction.
Background
In the prior art, when a hole site at the middle position of a part is punched, a wedge mechanism is required to complete the punching, and the requirement on tolerance of the hole site is higher. The prior wedge structure has the problems of large required space, small flexibility, low punching precision and the like.
Thus, the prior art is subject to improvements and improvements.
SUMMERY OF THE UTILITY MODEL
To the technical problem who exists among the prior art, the utility model aims at providing a cylinder slide wedge structure of guide pillar guide pin bushing direction that the space is little, the flexibility is big, the precision of punching a hole is high.
In order to achieve the above object, the utility model adopts the following technical scheme:
a needle cylinder wedge structure for guiding a guide post and a guide sleeve comprises a driving block, a guide plate, a base plate, nitrogen springs, a clamping plate, the guide sleeve, the guide post and a punch, wherein the lower part of the driving block is provided with an inclined plane, the guide plate is arranged on the inclined plane, the base plate is arranged on the guide plate, the guide post is arranged on the base plate, the guide sleeve is movably sleeved outside the guide post, the guide sleeve is arranged in the clamping plate in a penetrating manner, and two nitrogen springs are oppositely arranged between the clamping plate and the base plate; a punch head arranged on the base plate is arranged in the guide post; the side of the driving block is provided with a return hook, and the free end of the return hook extends inwards to form a limiting part in movable contact with the base plate.
Compared with the prior art, the beneficial effects of the utility model are that:
due to the adoption of the structural design, the punching machine has the advantages of small occupied space, high flexibility and high punching precision.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The reference numbers in the figures are respectively: (1) the device comprises a driving block, (2) a guide plate, (3) a backing plate, (4), (5) a nitrogen spring, (6) a clamping plate, (7) a guide sleeve, (8) a guide post, (9) a punch, (10) a return hook and (11) a limiting part.
Detailed Description
The invention will be described in further detail with reference to the accompanying drawings:
referring to fig. 1, the utility model relates to a cylinder slide wedge structure of guide pillar and guide bushing direction, including driving block 1, baffle 2, backing plate 3, nitrogen spring 4 and 5, splint 6, guide bushing 7, guide pillar 8 and drift 9, the lower part of driving block 1 has an inclined plane, is equipped with on this inclined plane baffle 2, be equipped with on the baffle 2 the backing plate 3, be equipped with on the backing plate 3 the guide pillar 8, the guide pillar 8 outer movable sleeve has the guide bushing 7, the guide bushing 7 is worn to be arranged in the splint 6, be equipped with two nitrogen spring 4 and 5 between splint 6 and the backing plate 3 relatively; a punch 9 arranged on the backing plate is arranged in the guide post 8; the side of the driving block 1 is provided with a return hook 10, and the free end of the return hook extends inwards to form a limiting part 11 which is in movable contact with the base plate.
The utility model discloses the during operation, the drive block downstream, the baffle is pressing the backing plate and is leading smooth motion, through compression nitrogen spring, guide pillar and guide pin bushing friction, accomplishes the action of punching a hole, punches a hole and accomplishes the back, and nitrogen spring's power is used in on the backing plate, and the drift passes through guide pillar and guide pin bushing direction return stroke, resets.
To sum up, the utility model discloses an foretell structural design solves the weak point among the prior art, has design benefit, space characteristics such as little, the precision height of punching a hole.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
