Description

Technical Field

[0001] This utility model relates to the field of bending technology, specifically to a floating pressure assembly for a multi-station continuous die. Background Technology

[0002] In the existing technology, the bending of thin aluminum alloy sheets is generally carried out using traditional sheet metal bending machines, which are usually equipped with a single upper and lower die. During operation, only one aluminum sheet can be placed in the die cavity at a time, and the bending process is completed by driving the upper die to press down.

[0003] The single-station operation mode has low production efficiency and cannot meet the needs of batch processing. Especially in situations where multiple bends at different angles or in different shapes are required, operators need to frequently change molds or reposition the sheet metal, which not only increases labor intensity and production time, but also easily leads to cumulative errors due to multiple clamping, affecting the product forming accuracy and consistency. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a floating pressure component for a multi-station continuous die to solve the problem of low production efficiency in single-station operation mode, which cannot meet the needs of batch processing.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a floating pressure assembly for a multi-station progressive die, comprising: frame; A support platform, which is fixed to one side of the frame; The lower mold kit includes various lower mold bodies of different specifications, wherein the various lower mold bodies are arranged along a straight line and detachably connected to the top of the support platform; An upper mold body, which is located directly above a variety of lower mold bodies; The first driving component is mounted on the frame and is used to drive the upper mold body to move in a direction close to the lower mold body.

[0006] The beneficial effects of this utility model are: 1) By arranging various lower molds of different specifications in a straight line on the support platform, and cooperating with a common upper mold, multiple aluminum plates can be bent continuously and synchronously on the same machine, which greatly improves the output efficiency per unit time. At the same time, the lower mold adopts a detachable connection method, which makes it easy to flexibly adjust the mold combination according to different product requirements, supports flexible production of multiple varieties and small batches, and enhances the applicability and economy of the equipment.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the lower mold kit includes multiple lower mold bodies with different mold groove widths but the same depth.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by configuring a series of lower mold bodies with different groove widths but the same depth, multiple aluminum plates placed on them can be bent simultaneously at one time. The different widths of the mold grooves can correspond to different bending radius requirements, thereby realizing the bending and forming of multiple parts of the same or different specifications in one pressing stroke.

[0010] Furthermore, the first driving component includes a first hydraulic cylinder, a rocker arm, a lower pressure plate, a connecting arm, a first guide rail, and a first slider. The rocker arm is rotatably connected to both sides of the frame via a rotating shaft. The first hydraulic cylinder is located below the rocker arm and fixed on the frame, and the driving end of the first hydraulic cylinder is rotatably connected to one side of the rocker arm via a rotating shaft.

[0011] Furthermore, one end of the connecting arm is rotatably connected to the other side of the swing arm via a pivot, the top of the lower pressure plate is rotatably connected to the other end of the connecting arm via a pivot, the first slider is fixed on both sides of the frame, the first guide rail slides on the first slider and is fixed on one side of the lower pressure plate, and the upper mold body is detachably connected to the bottom of the lower pressure plate.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the rocker arm is driven to rotate by the first hydraulic cylinder, so that one side of the rocker arm rotates downward, and pushes the connecting arm and the lower pressure plate to move downward through the first guide rail to the first slider, thereby pulling the upper mold body to press against the lower mold body.

[0013] Furthermore, the lower mold kit includes multiple lower mold bodies with the same mold groove width but different depths.

[0014] Furthermore, the support platform has multiple slots arranged side by side inside.

[0015] Furthermore, each of the slots is provided with a second driving component for driving the lower mold body to move in a direction close to the upper mold body.

[0016] Furthermore, each of the second driving components includes a second guide rail and a second slider, a second hydraulic cylinder, and a horizontal plate. The second slider is fixed to the side walls on both sides of the slot. One end of the second guide rail slides on the second slider. The horizontal plate is fixed to the other end of the second guide rail. The second hydraulic cylinder is fixed to the bottom of the slot, and the driving end of the second hydraulic cylinder is fixed to the bottom of the horizontal plate. A plurality of the lower mold bodies are arranged along a straight line and detachably connected to the top of the horizontal plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by configuring a series of lower molds with the same mold groove width but different depths, it can meet the needs of different bending angles. In order to avoid the upper mold pressing on the shallow lower mold, which would damage the shallow lower mold and interfere with the bending operation, the second hydraulic cylinder can be used to drive the horizontal plate to drive the second guide rail to slide upward on the two sliders, thereby raising the lower mold with the deeper mold groove, and bending the aluminum plate on the raised lower mold separately.

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] In the existing technology, the bending of thin aluminum alloy sheets is generally carried out using traditional sheet metal bending machines, which are usually equipped with a single upper and lower die. During operation, only one aluminum sheet can be placed in the die cavity at a time, and the bending process is completed by driving the upper die to press down.

[0022] The single-station operation mode has low production efficiency and cannot meet the needs of batch processing. Especially in situations where multiple bends at different angles or shapes are required, operators need to frequently change molds or reposition the sheet metal, which not only increases labor intensity and production time, but also easily leads to cumulative errors due to multiple clamping, affecting the product forming accuracy and consistency. In response, the inventor has proposed a floating pressure component for a multi-station continuous mold to solve the above problems.

[0023] The present invention provides the following preferred embodiments. Example 1 like Figure 1 and Figure 2 As shown, the floating blank holder assembly of a multi-station progressive die includes: 100 racks; Support platform 700, which is fixed to one side of frame 100; The lower mold kit includes various lower mold bodies 200 of different specifications, wherein the various lower mold bodies 200 are arranged in a straight line and detachably connected to the top of the support platform 700; The upper mold body 300 is located directly above the various lower mold bodies 200; The first driving component 400 is disposed on the frame 100 and is used to drive the upper mold body 300 to move in a direction close to the lower mold body 200. By arranging various lower mold bodies 200 of different specifications in a straight line on the support platform 700, and cooperating with a common upper mold body 300, the bending of multiple aluminum plates can be completed continuously and synchronously on the same machine, which greatly improves the output efficiency per unit time. At the same time, the lower mold body 200 adopts a detachable connection method, which makes it easy to flexibly adjust the mold combination according to different product requirements, supports flexible production of multiple varieties and small batches, and enhances the applicability and economy of the equipment.

[0024] In this embodiment, as Figure 1 , Figure 2 ,and Figure 3 As shown, the lower mold kit includes a variety of lower mold bodies 200 with different groove widths but the same depth. By configuring a series of lower mold bodies 200 with different groove widths but the same depth, the component can simultaneously bend multiple aluminum plates placed on it. Different groove widths can correspond to different bending radius requirements, thereby enabling the bending and forming of multiple parts of the same or different specifications to be completed in one pressing stroke.

[0025] In this embodiment, as Figure 1 , Figure 2 ,and Figure 3As shown, the first driving component 400 includes a first hydraulic cylinder 401, a rocker arm 402, a lower pressure plate 403, a connecting arm 404, a first guide rail 405, and a first slider 406. The rocker arm 402 is rotatably connected to both sides of the frame 100 via a rotating shaft. The first hydraulic cylinder 401 is located below the rocker arm 402 and fixed on the frame 100. The driving end of the first hydraulic cylinder 401 is rotatably connected to one side of the rocker arm 402 via a rotating shaft. One end of the connecting arm 404 is rotatably connected to the other side of the rocker arm 402 via a rotating shaft. The top of the lower pressure plate 403 is rotatably connected to the other end of the connecting arm 404 via a rotating shaft. The first slider 406 is fixed on both sides of the frame 100. The first guide rail 405 slides on the first slider 406 and is fixed to one side of the lower pressure plate 403. The upper mold body 300 is detachably connected to the bottom of the lower pressure plate 403. The first hydraulic cylinder 401 drives the rocker arm 402 to rotate, causing one side of the rocker arm 402 to rotate downwards, and pushes the connecting arm 404 and the lower pressure plate 403 to move downwards through the first guide rail 405 and the first slider 406, thereby pulling the upper mold body 300 to press against the lower mold body 200.

[0026] Example 2 refer to Figures 1-4 Compared to Embodiment 1, in Embodiment 2, the lower mold kit includes multiple lower mold bodies 200 with the same mold groove width but different depths. The support platform 700 has multiple parallel slots 500 inside. Each slot 500 has a second driving member 600 for driving the lower mold body 200 to move in a direction close to the upper mold body 300. Each second driving member 600 includes a second guide rail 601, a second slider 602, a second hydraulic cylinder 603, and a horizontal plate 604. The second slider 602 is fixed to the side walls on both sides of the slot 500. One end of the second guide rail 601 slides on the second slider 602. The horizontal plate 604 is fixed to the other end of the second guide rail 601. The second hydraulic cylinder 603 is fixed to the bottom of the slot 500, and the driving end of the second hydraulic cylinder 603 is fixed to the bottom of the horizontal plate 604. Multiple lower mold bodies 200 are arranged in a straight line and detachably connected to the top of the horizontal plate 604. By configuring a series of lower mold bodies 200 with the same width but different depths, different bending angles can be accommodated. In order to avoid the upper mold body 300 pressing on the shallower lower mold body 200, which would damage the shallower lower mold body 200 and interfere with the bending operation, the second hydraulic cylinder 603 can be used to drive the horizontal plate 604 to drive the second guide rail 601 to slide upward on the second slider 602, thereby raising the lower mold body 200 with the deeper mold groove, and bending the aluminum plate on the raised lower mold body 200 separately.

[0027] The specific working process of this utility model is as follows: (1) To meet different bending radius requirements First, by configuring a series of lower mold bodies 200 with different groove widths but the same depth, multiple aluminum plates placed on them can be bent simultaneously at one time. Different groove widths can correspond to different bending radius requirements, thereby enabling the bending and forming of multiple parts of the same or different specifications to be completed in one pressing stroke.

[0028] (2) Requirements for different bending angles By configuring a series of lower mold bodies 200 with the same width but different depths, different bending angles can be accommodated. In order to avoid the upper mold body 300 pressing on the shallower lower mold body 200, which would damage the shallower lower mold body 200 and interfere with the bending operation, the second hydraulic cylinder 603 can be used to drive the horizontal plate 604 to drive the second guide rail 601 to slide upward on the second slider 602, thereby raising the lower mold body 200 with the deeper mold groove, and bending the aluminum plate on the raised lower mold body 200 separately.

[0029] (3) Situations where bending requirements are the same To meet the requirement of having the same bending radius and bending angle, the lower mold 200 on the horizontal plate 604 can be replaced with the same specification, which can not only press multiple aluminum plates at the same time, but also bend larger aluminum plates.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
