Abstract

The invention relates to the field of automobile manufacturing, in particular to a lifting punching device which realizes effective switching to or not to punch without removing a mould. The technical scheme adopted by the invention is as follows: in a lifting punching device, a punch is arranged on a mould seat, and an adjusting mechanism for adjusting the height of the punch and a limit mechanism for limiting the moving direction of the punch are arranged in the mould seat. Through the technical scheme, the adjusting mechanism can realize the lifting movement of the punch, and the limit mechanism can ensure that the punch always moves in the vertical direction during the lifting. The device is simple to operate, convenient to use and low in manufacturing cost, and can effectively save the mould development cost and improve the production efficiency.

Description

A kind of liftable hole punched device

Technical field

The present invention relates to automobile manufacturing field, be specifically related to a kind of liftable hole punched device.

Background technology

At present, the automobile body covering piece mould is that requirement was the highest during body of a motor car was made, the mould of difficulty of processing maximum, also be on the cold punching technology equipment automobile body covering piece mould that develops rapidly in China's electronic product manufacturing punch mechanism to be arranged more, to process many moneys vehicle on the processing platform of automobile panel, need punching a little, need not punching a little, processing technology according to present employing, generally need to increase the punching operation, improved the manufacturing cost of mould itself greatly, and when carrying out the production of automation line, increased mould replacing time, reduced production efficiency.

Summary of the invention

The purpose of this invention is to provide a kind of liftable hole punched device, under the situation of not dismantling mould, realize effective switching of whether punching.

For achieving the above object, the present invention by the following technical solutions, a kind of liftable hole punched device, drift is located on the die holder, be provided with in the die holder regulate the drift height governor motion and the position-limit mechanism of the restriction drift direction of motion.

By above technical scheme, governor motion can be realized the drift elevating movement, and position-limit mechanism can guarantee that drift remains the vertical direction motion in lifting process simultaneously.This device is simple to operate, and is easy to use, and low cost of manufacture can effectively be saved the mould development cost, enhances productivity.

The specific embodiment

A kind of liftable hole punched device, drift 10 are located on the die holder 20, be provided with in the die holder 20 regulate drift 10 height governor motion 30 and the position-limit mechanism 40 of restriction drift 10 directions of motion.When the needs punching, can drift 10 be risen by governor motion 30; When not needing punching, by governor motion 30 drift is fallen equally.Position-limit mechanism 40 mainly plays guarantees that drift 10 is positioned at the vertical direction lifting all the time rising and fall in the process, thereby reaches the purpose of accurate punching.

Described governor motion 30 comprises the upper and

lower slide block

50,60 of move toward one another, mating surface between the upper and

lower slide block

50,60 is the inclined-plane, upper and

lower slide block

50,60 is positioned at the die cavity 21 of die holder 20, the bottom surface of the upper surface of top shoe 50 and drift 10 reclines, sliding block 60 is connected with the leading screw and nut mechanism of regulating its horizontal motion, and top shoe 50 is fitted with the inwall of die cavity 21 on the direction of motion of sliding block 60 and constituted being slidingly matched of vertical direction.Promptly when leading screw and nut mechanism drive sliding block 60 advanced in the horizontal direction or retreats, top shoe 50 can only move under the in the vertical direction under the position-limiting action of the inwall of die cavity 21, thereby realized the lifting of drift.

Further, the cross sectional shape of described die cavity 21 is a rectangle, this cross section is the horizontal direction cross section, sliding block 60 to move horizontally direction consistent with the length direction of die cavity 21, guarantee that being slidingly matched between the

slide block

50,60 is converted into the vertical lift of drift 10 up and down.

Further again, described leading screw and nut mechanism comprises T type bolt 70, and the sidepiece of the side plate 22 of die holder 20 is provided with screwed hole 221, the sidepiece of sliding block 60 is provided with ringent T type groove 61, and the head of T type bolt 70 is located in the T type groove 61, its thread segment shaft and screwed hole 221 formation threaded engagement.T type bolt 70 herein is actual to be that the thread segment shaft two ends of bolt all are provided with head, an end be conventional turret head for screwing use, the other end is a T connector, this T connector is in order to cooperate with T type groove 61, to realize that both promptly axially are synchronized with the movement by axial limiting.When rotating T type bolt 70, the head of T type bolt 70 can promote sliding block 60 and do rectilinear motion in the horizontal direction.Can not damage T type bolt 70 for guaranteeing simultaneously, be matched in clearance between T type bolt 70 and the T type groove 61.

Described position-limit mechanism 40 is a drift fixed head 41, and drift 10 passes formation and is slidingly matched from the through hole of plate body, and drift fixed head 41 is located at the upper end open place of die cavity 21.Drift fixed head 41 has played good spacing guide effect with being slidingly matched of drift 10 to drift 10, can guarantee that drift remains vertical motion in lifting process.

In order to guarantee in sliding block 60 motion process in the horizontal direction, the height that top shoe 50 rises is suitable, upper and

lower slide block

50,60 can bear the bigger surge on the vertical direction simultaneously, and the inclined-plane that matches between the described upper and

lower slide block

50,60 and the angle of horizontal direction are 30 °～40 °.
