Description

Technical Field

[0001] This utility model relates to the technical field of edge trimming devices, specifically an integrated aluminum subframe edge trimming device. Background Technology

[0002] Low-pressure casting of one-piece aluminum subframes has a complex structure. After casting, there are flashes on both the inner and outer sides. A press is needed to drive an upper mold frame with cutters to remove the flashes. When the existing one-piece aluminum subframe trimming device trims the flashes, the inner and outer cutters contact the flashes simultaneously and cut them off at the same time. The resistance encountered during trimming is relatively large, and the required trimming force is large. A large press must be used, which increases the cost. Moreover, the trimmed flashes cannot fall off, affecting product positioning and causing product damage. Utility Model Content

[0003] The main purpose of this utility model is to provide an integrated aluminum subframe trimming device to solve the problems in the prior art where the existing integrated aluminum subframe trimming device requires a large trimming force when trimming burrs, necessitates the use of a large press, and results in high costs; and the trimmed burrs affect product positioning and cause product damage.

[0004] To achieve the above objectives, this utility model provides an integrated aluminum subframe trimming device, including an upper mold frame for trimming flash and a lower mold frame for positioning the aluminum subframe. The upper mold frame includes flash cutters, which include an inner cutter for trimming the inner flash of the aluminum subframe and an outer cutter for trimming the outer flash of the aluminum subframe. The positions of the outer cutter and the inner cutter satisfy the following condition: when the aluminum subframe is positioned on the lower mold frame, the distance between the outer cutter and the outer flash of the aluminum subframe is greater than the distance between the inner cutter and the inner flash of the aluminum subframe.

[0005] Furthermore, when the aluminum subframe is positioned on the lower mold frame, the distance between the outer cutter and the outer flash of the aluminum subframe is 20-50mm larger than the distance between the inner cutter and the inner flash of the aluminum subframe.

[0006] Furthermore, the upper mold frame includes a clamping block connecting plate, an upper template, and multiple cutting blade connecting rods. The upper template is located below the clamping block connecting plate. The bottom of the cutting blade connecting rod is fixedly connected to a flash cutter, the middle is fixedly connected to the upper template, and the top is movably connected to the clamping block connecting plate.

[0007] Furthermore, the top ends of multiple clamping block connecting rods are fixedly connected to the clamping block connecting plate, and clamping blocks are fixedly connected to the bottom of the clamping block connecting rods. The middle part of the clamping block connecting rods is slidably connected to the upper template. The clamping block connecting plate is provided with sliding holes that are slidably connected to the cutter connecting rods. The top of the cutter connecting rod is provided with a limit cap, and a buffer spring is sleeved on the outside of the cutter connecting rod. The buffer spring is located between the limit cap and the clamping block connecting plate.

[0008] Furthermore, the upper template is fixedly connected with several sliding columns, and the clamping block connecting plate is provided with sliding holes that are slidably connected to the sliding columns.

[0009] Furthermore, the lower mold frame is equipped with support limiting blocks for supporting and positioning the aluminum subframe.

[0010] Furthermore, the lower die holder is provided with a blanking hole for the cut-off flash to fall downwards.

[0011] This invention, by making the distance between the outer cutting blade and the outer edge of the aluminum subframe greater than the distance between the inner cutting blade and the inner edge of the aluminum subframe, allows the inner cutting blade to cut the inner edge first, followed by the outer cutting blade cutting the outer edge, thus cutting the flash in two stages. This results in less resistance during cutting, less cutting force required, a smaller pressing machine, and lower cost.

[0012] This invention, by setting a material drop hole, allows the cut-off burrs to fall through the hole, preventing them from accumulating and affecting product positioning or causing product damage. Attached Figure Description

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 8 As shown, an embodiment of an integrated aluminum subframe trimming device includes an upper mold frame 1 for trimming flash and a lower mold frame 2 for positioning the aluminum subframe 3. The upper mold frame 1 includes flash cutters, which include an inner cutter 104 for trimming the inner flash of the aluminum subframe 3 and an outer cutter 106 for trimming the outer flash of the aluminum subframe 3. The positions of the outer cutter 106 and the inner cutter 104 satisfy the following condition: when the aluminum subframe 3 is positioned on the lower mold frame 2, the distance between the outer cutter 106 and the outer flash of the aluminum subframe 3 is 25mm greater than the distance between the inner cutter 104 and the inner flash of the aluminum subframe 3.

[0025] like Figure 1 and Figure 2 As shown, the upper mold frame 1 includes a clamping block connecting plate 101, an upper template 102, and multiple cutting blade connecting rods 103. The upper template 102 is located below the clamping block connecting plate 101, and an annular connecting frame 1011 is fixedly connected to the top edge of the upper template 102. A flash cutter is fixedly connected to the bottom of the cutting blade connecting rod 103, the upper template 102 is fixedly connected to the middle part, and the top part is movably connected to the clamping block connecting plate 101.

[0026] like Figure 2 As shown, the top ends of a plurality of pressing block connecting rods 107 are fixedly connected to the pressing block connecting plate 101, and pressing blocks 108 are fixedly connected to the bottom of the pressing block connecting rods 107. The middle part of the pressing block connecting rods 107 is slidably connected to the upper template 102. The upper template 102 is provided with sliding holes that are slidably connected to the pressing block connecting rods 107.

[0027] like Figure 2 As shown, the clamping block connecting plate 101 is provided with a sliding hole that is slidably connected to the cutter connecting rod 103; the top of the cutter connecting rod 103 is provided with a limit cap 1010, and the buffer spring 105 is sleeved on the outside of the cutter connecting rod 103 and located between the limit cap 1010 and the clamping block connecting plate 101.

[0028] like Figure 1and 2 As shown, four sliding columns 109 are fixedly connected to the top of the upper template 102. The four sliding columns 109 are evenly distributed on the top edge of the upper template 102. The pressing block connecting plate 101 is provided with sliding holes that are slidably connected to the sliding columns 109.

[0029] like Figure 7 As shown, the lower mold frame 2 is provided with a support limiting block 201 for supporting and positioning the aluminum subframe 3; the lower mold frame 2 is provided with a blanking hole 202 for causing the cut-off burrs to fall downwards.

[0030] The method of using the integrated aluminum subframe trimming device in this embodiment is as follows:

[0031] The press is connected to the upper template 102 via the connecting frame 1011; the aluminum subframe 3 is positioned on the lower mold frame 2; the press drives the upper template 102 to move downward, and the upper template 102 drives the outer cutter 106 and the inner cutter 104 to move downward to cut the flash of the aluminum subframe 3;

[0032] The distance between the outer cutting blade 106 and the outer edge of the aluminum subframe 3 is greater than the distance between the inner cutting blade 104 and the inner edge of the aluminum subframe 3. This allows the inner cutting blade 104 to cut the inner edge first, followed by the outer cutting blade 106 cutting the outer edge. This two-stage cutting of the flash results in less resistance, less cutting force, a smaller pressing machine, and lower cost.

[0033] When trimming the burrs, the clamping block 108 clamps the aluminum subframe 3 to prevent it from moving during the trimming process; the buffer spring 105 acts as a buffer to prevent the clamping block 108 from damaging the aluminum subframe 3.

[0034] The cut-off burrs fall through the material drop hole 202, preventing them from piling up and affecting product positioning or causing product damage.

[0035] Existing integrated aluminum subframe trimming devices use both inner and outer cutters to simultaneously cut off the burrs during trimming. However, this process involves significant resistance and requires substantial cutting force, necessitating the use of presses with a capacity of 350T or higher, resulting in high procurement costs. Furthermore, the cut burrs cannot be removed, affecting product positioning and causing product damage, leading to a product yield rate of only 95%-98%.

[0036] This embodiment features an integrated aluminum subframe trimming device that cuts the flash in two stages, resulting in less resistance and less cutting force. It uses a 200T press, which has a lower purchase price. The cut flash falls directly from the discharge hole, preventing it from accumulating and affecting product positioning or causing damage. The product yield is 100%.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
