Progressive die floating plate inclined wedge mechanism

Abstract

A continuous die floating plate inclined wedge mechanism is used in the field of die manufacturing technology. The sliding seat is connected to the lower template through equal-height screws and springs. The slider is installed in the sliding seat and is in sliding fit with the sliding seat. The return spring is installed in the slider, and the baffle is connected to the sliding seat through screws. The inserting knife is locked in the fixed groove of the lower template through screws. The strip moves along the feeding direction on the slider. During the downward movement of the upper template, the sliding seat and the slider are driven to move downward. When the slider contacts the inserting knife and is pushed by the inserting knife, the slider is separated from the strip. During the process that the upper template and the slider continue to move downward to the bottom dead center, the strip is blanked and cut, and the waste part of the strip freely falls and falls into the blanking hole of the lower template. The invention can not only meet the feeding of the product strip on the floating plate with a certain floating height, but also smoothly fall and discharge out of the die after the strip is blanked and cut into waste. The structure is simple and it is an independent mechanism, which can effectively ensure the stability and feeding accuracy of the continuous die feeding.

Description

Technical Field

[0001] The present invention relates to the technical field of die manufacturing, and specifically to a floating plate inclined wedge mechanism for a stamping progressive die. Background Art

[0002] In the prior art, when designing and manufacturing a stamping progressive die for automotive product parts, it is encountered that the strip of the product needs to be fed on a floating plate that floats to a certain height and is also cut into waste. When the waste falls, it interferes with the floating plate and cannot be smoothly discharged from the die. Usually, the floating plate is shortened to avoid interference, which easily causes insufficient support for the strip during feeding, affecting the feeding stability and feeding accuracy. Summary of the Invention

[0003] To overcome the deficiencies of the prior art, the object of the present invention is to provide a floating plate inclined wedge mechanism for a progressive die, so as to meet the requirements that the strip of the product can not only float and feed on the floating plate, but also smoothly fall and be discharged outside the die after being cut into waste by blanking.

[0004] To achieve the above object of the invention, the slide base of the present invention is connected to the lower template through equal-height screws and springs. The slider is installed in the slide base and is slidably matched with the slide base. The return spring is installed in the slider, and the baffle is connected to the slide base through screws; the inserting knife is locked in the fixing groove of the lower template through screws, and the strip moves along the feeding direction on the slider; during the downward movement of the upper template, the slide base and the slider are driven to move downward. When the slider contacts the inserting knife and is pushed by the inserting knife, the slider is separated from the strip.

[0005] The slide base is provided with a slideway for the slider to slide therein, a limit groove for limiting the limit hanging platform of the slider, and a through hole for the inserting knife to insert into the slide base.

[0006] The slider is provided with a blind hole for installing the return spring. The upper end of the end of the slider is provided with a limit hanging platform. The slider is also provided with a driving inclined surface 1 that contacts the driving inclined surface 2 of the inserting knife, and a through hole for the inserting knife to insert into the slider.

[0007] The lower template is provided with a blanking hole.

[0008] The upper part of the inserting knife is provided with a driving inclined surface 2 that contacts the driving inclined surface 1 of the slider.

[0009] Compared with the prior art, the present invention can not only meet the feeding of the strip of the product on the floating plate that floats to a certain height, but also smoothly fall and be discharged outside the die after the strip is cut into waste by blanking. The structure is simple and it is an independent mechanism, which can effectively ensure the feeding stability and feeding accuracy of the progressive die. Brief Description of the Drawings

[0010] Figure 1 It is a schematic diagram of the open die of the present invention.

[0011] Figure 2 This is the schematic diagram of the closed die of the present invention. Specific embodiments

[0012] As Figure 1 、 Figure 2 shown, the slide block 1 of the present invention is connected to the lower template 6 through equal-height screws and springs. The slider 2 is installed in the slide block 1 and is in sliding fit with the slide block 1. The return spring 3 is installed in the slider 1. The baffle 4 is connected to the slide block 1 through screws; the inserting knife 5 is locked in the fixing groove of the lower template 6 through screws. The strip 7 moves along the feeding direction on the slider 2. When the upper template 8 moves downward, it drives the slide block 1 and the slider 2 to move downward. When the slider 2 contacts the inserting knife 5 and is pushed by the inserting knife 5, the slider 2 is separated from the strip 7.

[0013] The slide block 1 is provided with a slideway for the slider 2 to slide therein. The slide block 1 is also provided with a limit groove 10 for limiting the limit platform 9 of the slider 2. The slide block 1 is provided with a through hole for the inserting knife 5 to insert into the slide block 1.

[0014] The slider 2 is provided with a blind hole for installing the return spring 3. The upper end of the end of the slider 2 is provided with a limit platform 9. The slider 2 is also provided with a driving inclined surface 11 in contact with the driving inclined surface 2 12 of the inserting knife 5, and a through hole for the inserting knife 5 to insert into the slider 2.

[0015] The upper part of the inserting knife 5 is provided with a driving inclined surface 2 12 in contact with the driving inclined surface 11 of the slider 2.

[0016] The lower template 6 is provided with a blanking hole 13.

[0017] The working process of the die of the present invention: Under the transportation of the feeder, the strip 7 moves one pitch along the feeding direction on the slider 2, and then the feeder and the strip 7 stop moving. The upper template 8 moves downward, contacts the slide block 1, and drives the slide block 1, the slider 2, the return spring 3, and the baffle 4 to move downward. During the downward movement of the slider 2, it contacts the inserting knife 5 and is pushed by the inserting knife 5. Then the slider 2 moves horizontally in the slideway of the slide block 1 and is separated from the strip 7. During the process that the upper template 8 and the slider 2 continue to move downward to the bottom dead center, the strip 7 is blanked and cut. The waste part of the strip 7 freely falls and falls into the blanking hole 13 of the lower template 6.

[0018] The die return process: The upper template 8 moves upward. The slide block 1, the slider 2, the return spring 3, and the baffle 4 move upward under the action of the spring force; the slider 2 moves upward and is separated from the inserting knife 5, and under the action of the return spring 3, it moves horizontally in the slide block 1 to the dead center.
