Swing tapered wedge structure of sealing plate progressive die

Abstract

The utility model discloses a swing tapered wedge structure of a sealing plate progressive die, which comprises a die bottom plate, the end part of the die bottom plate is provided with a support plate die for bearing a workpiece, one side of the support plate die is provided with a tapered wedge seat positioned on the surface of the die bottom plate, and the tapered wedge seat is used for wedging the side edge of the workpiece. When the inclined face of the driving inclined wedge base presses downwards, the swing inclined wedge block swings towards one side, meanwhile, the downward pressing inclined wedge base moves downwards to enable the limiting inclined wedge groove in one side face of the downward pressing inclined wedge base to press downwards the top end of the swing inclined wedge block for limiting and fixing, and therefore the side edge of a pressed sealing plate workpiece on a carrier plate mold can be clamped. Through cooperation of the structural parts and linkage of the swing wedge block and the wedge linkage base, the swing wedge block can achieve the effect that a sealing plate workpiece is clamped by a swing wedge, and due to the inclined face pushing mode of the wedge linkage base, the phenomenon that the swing wedge block and the downward pressing wedge base are clamped in the wedge process is avoided.

Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a swinging wedge structure of a sealing plate advance mold. Background Art

[0002] During the design process of stamping dies, many processes are completed by the inclined wedge mechanism, such as side punching, side trimming or side flanging. When the stamping process is determined, the mold designer selects a standard inclined wedge structure or designs different non-standard inclined wedge structures to complete the above process content according to the angle and stroke of the side punching and side trimming in the process. In the related art, the driving block of the inclined wedge structure directly drives the inclined wedge to complete the above process content. For example, the inclined wedge and the driving block use the form of inclined surface and inclined surface matching or inclined surface and roller matching to complete the driving block to drive the inclined wedge. The above driving method is difficult to meet the customer's demand for a large stroke of the inclined wedge, that is, the above driving method cannot achieve a side punching or side trimming process with a larger stroke, and there is room for improvement.

[0003] To this end, a wedge structure of a mold is disclosed with the announcement number "CN103990719B". The wedge structure of the mold comprises: a wedge, which is slidably disposed on the lower mold of the mold; a cam, which is rotatably disposed on the lower mold around the rotation axis of the cam; and a driving block, which is disposed on the upper mold of the mold, and is suitable for driving the wedge to slide through the cam. According to the wedge structure of the mold in an embodiment of the present invention, the driving block indirectly drives the wedge through the cam, and changing the outer contour line of the cam can change the size of the sliding stroke of the wedge, thereby meeting the requirements of different process contents and making the use of the wedge structure more convenient.

[0004] However, for the above-mentioned inclined wedge structure of the mold, although the mating surfaces of the driving block and the cam are both toothed surfaces, and the power transmission is achieved through the mutual engagement of the driving teeth and the first meshing teeth, thereby making the transmission more stable and further improving the working stability of the inclined wedge structure, there are still the following obvious defects during use: the driving block reciprocates up and down to drive the cam toothed surface to swing, but due to the up and down movement and dissolution of the driving block, the driving teeth and the toothed surface are constantly engaged and rotated, which can easily cause one end of the cam driving tooth to get stuck in the toothed surface, thereby easily causing the teeth of the driving tooth to get stuck, worn and broken. Utility Model Content

[0005] The utility model aims to provide a swinging wedge structure of a sealing plate advancing die to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a swinging wedge structure of a sealing plate advancing mold, comprising:

[0008] The mold pressing plate is vertically arranged at the upper end of the mold bottom plate, and a downward pressing wedge seat is provided on one side of the lower end surface of the mold pressing plate for cooperating with the wedge seat to swing the wedge, and a driving wedge block is provided on one side of the downward pressing wedge seat for driving the wedge linkage seat to wedge.

[0009] Preferably, a punching groove is provided on the inclined wedge seat, and a punching seat for punching the sealing plate workpiece is fixedly provided at a position at the bottom end of the punching groove corresponding to one side of the carrier mold, so that the punching seat passes through the punching groove to punch the sealing plate workpiece and enhances the stability of the inclined wedge seat in the carrier mold.

[0010] Preferably, the inclined wedge linkage seat is provided with a swing groove extending downward into a circular arc concave surface on one side of the inclined wedge seat corresponding to the inclined wedge seat, and a swinging inclined wedge block is movably connected to the swing groove through a pin shaft. The inclined wedge can be used to fix or clamp the sealing plate workpiece to ensure that the sealing plate workpiece does not move or fall off.

[0011] Preferably, the top of the swinging wedge block is fitted into a side of the pressing down wedge seat and a limiting wedge groove is provided, and the other side of the swinging wedge block is a downward inclined surface structure, and the inclined surface structure is fitted into the inclined surface at the bottom end of one side of the driving wedge block for pushing, which can ensure the stability of the swinging of the swinging wedge block.

[0012] Preferably, one side of the inclined wedge linkage seat is an arc surface, and the arc surface and the inclined wedge seat are combined to limit the swinging wedge degree of the swinging inclined wedge block, and are used to press the sealing plate workpiece in the mold to perform side clamping.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows: the swinging wedge structure of the sealing plate extreme mold, through the cooperation of the wedge seat, the wedge linkage seat, the pressing wedge seat, the driving wedge block and the swinging wedge block, can make the swinging wedge block swing to one side when the inclined surface of the driving wedge seat is pressed down, and at the same time, the downward movement of the pressing wedge seat causes the limiting wedge groove on one side to limit and fix the downward pressure of the top of the swinging wedge block, thereby clamping the side of the sealing plate workpiece after being pressed on the carrier plate mold. Through the cooperation of the above-mentioned structural parts and the linkage of the swinging wedge block and the wedge linkage seat, the swinging wedge block can perform the effect of swinging the wedge to clamp the sealing plate workpiece, and because the inclined surface of the wedge linkage seat pushes the way, the phenomenon of jamming between the swinging wedge block and the pressing wedge seat during the wedging process will not occur. At the same time, the mold gap can be adjusted to enhance the mold rigidity and stability, and it is also convenient for mold maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS
