Description

Technical Field

[0001] This utility model belongs to the field of stamping die technology, and in particular relates to a bending and forming die for sheet metal. Background Technology

[0002] In stamping operations, it is common to encounter workpieces that require concave or convex sidewalls, partial convex sidewalls, or irregular side profiles. Simply relying on stamping in the vertical direction cannot achieve lateral deformation. In this invention, the workpiece has a 90° bend, one side of which is already formed into a cylindrical shape, and the other side needs to have a groove added. The entire workpiece is made of sheet metal. Since the preceding process is completed using a progressive die, making improvements to the progressive die would be too costly. Therefore, a simple and efficient side forming die is needed to solve the processing situation of adding grooves to the side of a workpiece with a 90° bend. Summary of the Invention

[0003] The purpose of this utility model embodiment is to provide a bending and forming mold for sheet metal, aiming to solve the technical problem of adding grooves to the side of a workpiece with a 90° bend by providing a simple and efficient side forming mold.

[0004] The present invention is implemented as follows:

[0005] A bending and forming die for sheet metal includes a pair of symmetrically arranged concave dies fixed to the top surface of a lower template. The concave dies are slidably connected to a convex die via a second guide post. The convex die is detachably fixed to a second inclined block. The second inclined block is horizontally slidably connected to the top of a second support base via a guide plate. The second support base is fixed to the top surface of the lower template. The inclined surface of the second inclined block engages with the inclined surface of the first inclined block. The top of the first inclined block is fixedly connected to an upper template. The upper template and the lower template are movably connected via a first guide post. When the concave dies and the convex die are fully closed, the distance between the upper template and the top surface of the concave die is greater than the height of the portion of the sheet metal protruding from the top surface of the convex die.

[0006] Furthermore, each end of the lower template is provided with a first support seat, and an adjustment plate is provided inside the first support seat. The adjustment plate cooperates with the back side of the inclined surface of the first inclined block to provide guidance and back support for the first inclined block.

[0007] Furthermore, the top of the first inclined block penetrates the upper template and is fixedly connected by bolts.

[0008] Furthermore, the upper template is provided with a guide sleeve, and the first guide post is inserted into the guide sleeve.

[0009] Furthermore, the die is fixed on both sides of the fixed base, the fixed base is provided with through holes, and both sides of the die, and the inner side of the second guide post, are also provided with through holes. Bolts are provided in the through holes to fix the two dies symmetrically on both sides of the fixed base.

[0010] Furthermore, the die cavity is provided with a push rod in the middle, and the push rod is connected to a first spring, which is used to reset the push rod.

[0011] Furthermore, the second guide post is fixedly connected to the punch, and the second guide post is inserted into a blind hole at the side end of the die. A second spring is provided in the blind hole, and the second spring is used to reset the second guide post.

[0012] The positive effects of this utility model are as follows: When the upper template moves up and down along the first guide post 1, it drives the first inclined block to move up and down. The first inclined block cooperates with the second inclined block 9 through the inclined surface, driving the second inclined block to slide horizontally on the top surface of the second support seat under the guide plate, and driving the punch to reciprocate. During the movement of the punch along the second guide post, it closes and opens with the die, completing the pressing of the sheet metal. At the same time, since the distance between the upper template and the top surface of the die is greater than the height of the part of the sheet metal protruding from the top surface of the punch when the die and the die are fully closed, the part of the sheet metal that does not need to be pressed is avoided while the pressing is completed, and two parts are made in one mold, which improves the pressing efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1 to 5 The diagram shows the structure of a sheet metal bending and forming mold according to an embodiment of the present invention. The bending and forming mold includes a pair of symmetrically arranged concave dies 12 fixed to the top surface of the lower template 15. The concave dies 12 are slidably connected to the convex die 10 via a second guide post 11. The convex die 10 is detachably fixed together with a second inclined block 9. The second inclined block 9 is horizontally slidably connected to the top of a second support seat 8 via a guide plate 7. The second support seat 8 is fixed to the top surface of the lower template. The second inclined block 9 engages with the inclined surface of a first inclined block 4 via an inclined surface. The top of the first inclined block 4 is fixedly connected to the upper template 2. The upper template 2 and the lower template 15 are movably connected via a first guide post 1. When the concave dies 12 and the convex die 10 are fully closed, the distance between the upper template 2 and the top surface of the concave die is greater than the height of the portion of the sheet metal protruding from the top surface of the convex die.

[0023] In this embodiment of the utility model, when the upper template 2 moves up and down along the first guide post 1, it drives the first inclined block 4 to move up and down. The first inclined block 4 cooperates with the second inclined block 9 through the inclined surface, driving the second inclined block 9 to slide horizontally on the top surface of the second support seat 8 under the guidance of the guide plate 7, and driving the punch 10 to reciprocate. During the movement of the punch 10 along the second guide post 11, it closes and opens with the die 12 to complete the pressing of the sheet metal. At the same time, since the distance between the upper template 2 and the top surface of the die is greater than the height of the part of the sheet metal protruding from the top surface of the punch when the die 12 and the punch 10 are completely closed, the part of the sheet metal that does not need to be pressed is avoided while the pressing is completed, and two parts are made in one mold, which improves the pressing efficiency.

[0024] Specifically, such as Figures 1 to 5 As shown, a bending and forming die for sheet metal includes a pair of symmetrically arranged concave dies 12 fixed to the top surface of a lower template 15. The concave dies 12 are slidably connected to a convex die 10 via a second guide post 11. The convex die 10 is detachably fixed to a second inclined block 9. The second inclined block 9 is horizontally slidably connected to the top of a second support base 8 via a guide plate 7. The second support base 8 is fixed to the top surface of the lower template. The second inclined block 9 engages with the inclined surface of a first inclined block 4 via an inclined surface. The top of the first inclined block 4 is fixedly connected to an upper template 2. The upper template 2 and the lower template 15 are movably connected via a first guide post 1. When the concave dies 12 and the convex die 10 are fully closed, the distance between the upper template 2 and the top surface of the concave die is greater than the height of the portion of the sheet metal protruding from the top surface of the convex die.

[0025] The top surface of the upper template 2 is provided with a mold handle 3 for connecting and cooperating with the press.

[0026] The lower template 15 has a first support seat 5 at both ends. The first support seat 5 has an adjustment plate 6 inside. The adjustment plate 6 has several blind holes filled with copper-based graphite rods for lubrication. The adjustment plate 6 cooperates with the inclined back side of the first inclined block 4 to provide guidance and back support for the first inclined block 4.

[0027] The top of the first inclined block 4 penetrates the upper template 2 and is fixedly connected by bolts. Specifically, the upper template 2 has rectangular through holes at both ends and screw holes on the sides of the rectangular through holes. The first inclined block has a rectangular boss that cooperates with the rectangular through holes. The shoulder of the rectangular boss has a threaded hole. The bolt passes through the screw hole and is threadedly connected to the threaded hole to fix the first inclined block 4 and the upper template 2.

[0028] The upper template 2 is provided with a guide sleeve 101, and the first guide post 1 is inserted into the guide sleeve 101.

[0029] The die 12 is fixed on both sides of the fixed base 14. The fixed base 14 is provided with through holes. Both sides of the die 12 and the inner side of the second guide post 11 are also provided with through holes. Bolts are provided in the through holes to fix the two dies 12 symmetrically on both sides of the fixed base 14.

[0030] The die 12 is provided with a push rod 16 in the middle, and the push rod 16 is connected to a first spring 17, which is used to reset the push rod 16.

[0031] When the punch 10 and the die 12 are closed, the punch core 1001 fixed to the punch 10 presses the workpiece from the initial state 19 to the forming state 18. At this time, the punch core 1001 presses the workpiece tightly and completely fits the die core 13. During this process, the workpiece pushes the push rod 16 to compress the first spring 17. When the punch 10 and the die 12 separate, the first spring 17 releases its elastic potential energy and pushes the push rod 16 to push the workpiece out of the die 12.

[0032] The second guide post 11 is fixedly connected to the punch 10. The second guide post 11 is inserted into the blind hole at the side end of the die 12. A second spring 1101 is provided in the blind hole. The second spring 1101 is used to reset the second guide post 11.
