DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed below.

[0028] Example 1

[0029] like Figure 1 As shown, an aluminum casting trimming device includes a bracket 1 and a slide bar 2 fixedly connected to the bracket 1.

[0030] The center of the bracket 1 and the axis of the slide bar 2 are on the same straight line.

[0031] The slide bar 2 is provided with a male die slide groove 3, a female die slide groove 7 and a top plate 11 in sequence from bottom to top.

[0032] The punch slot 3 is fixedly connected to the slide bar 2.

[0033] The die slide 7 is slidably connected to the slide bar 2 and cooperates with the punch slide 3. The inner spacing between the two slides of the die slide 7 is equal to the outer spacing between the two slides of the punch slide 3. After the die slide 7 is pushed down by the cylinder 12, the punch slide 3 wraps and overlaps the die slide 7, thereby trimming the part 16. The top plate 11 is fixedly connected to the slide bar 2. A cylinder 12 is provided on the top plate 11. The cylinder rod 13 of the cylinder 12 is fixedly connected to the die slide 7 through the connecting plate 10.

[0034] The lower parts of both ends of the male die chute 3 are fixedly connected with male die connecting rods 4, the male die 5 is slidably connected with the male die chute 3, the upper parts of both ends of the female die chute 7 are fixedly connected with female die connecting rods 8, the female die 9 is slidably connected with the female die chute 7,

[0035] The punch connecting rod 4 is arranged at the lower part of both sides of the punch chute 3, and the die connecting rod 8 is arranged at the upper part of both ends of the die chute 7. When the punch chute 3 and the die chute 7 are matched, the two connecting rods do not contact, which can avoid the connecting rods interfering with the trimming operation. At the same time, the connecting rods can improve the stability of the punch chute 3 and the die chute 7.

[0036] The inner spacing of the two concave die slots 7 matches the outer spacing of the two convex die slots 3.

[0037] The die slide 7 is slidably connected to the slide rod 2 and cooperates with the punch slide 3. The inner spacing between the two slides of the die slide 7 is equal to the outer spacing between the two slides of the punch slide 3. After the die slide 7 is pushed down by the cylinder 12, the punch slide 3 wraps and overlaps the die slide 7.

[0038] like Figure 2 As shown, a boss 14 is provided on the punch 5, and a positioning column 15 of a cast aluminum part is provided on the boss 14. When the part 16 is trimming on the device, the body of the part 16 is placed on the boss 14 of the punch 5, and the ear wing 17 of the part 16 is sleeved on the positioning column 15, which can ensure that the part 16 will not shake during the trimming operation.

[0039] like Figure 3 As shown, a cutting groove for trimming the cast aluminum part is provided in the die 9. When the die slide groove 7 moves downward driven by the cylinder 12, the die 9 cooperates with the punch 5. The cutting groove in the die 9 covers the part 16 on the punch 5, and the burrs on the ear wings 17 of the part 16 outside the cutting groove are cut off.

[0040] A control box 6 is provided on the bracket 1, and a control button is provided on the control box 6. The control box 6 is electrically connected to the cylinder 12, and the control box 6 is electrically connected to the power supply for controlling the start and stop of the cylinder 12. The control box 6 is controlled based on the Siemens SIMATIC S7-200PLC controller. The control box 6 is provided with an anti-fool switch to protect the safety of the operation. The controller sends a start and stop command to the cylinder 12.

[0041] Example 2

[0042] In this embodiment, the two ends of the male die 5 and the female die 9 sliding in the slide groove are Z-shaped.

[0043] A plurality of punches 5 and die 9 are respectively arranged in the punch slot 3 and the die slot 7. Any two adjacent punches 5 are spliced ​​in a Z shape in the punch slot 3, and any two adjacent die 9 are spliced ​​in a Z shape in the die slot 7. The Z shape can make the splicing of the punch 5 and the die 9 in their respective slots more stable. At the same time, the two slots can install multiple punches 5 and die 9. When the cylinder 12 is pressed down at one time, multiple parts 16 can be processed, thereby improving production efficiency.

[0044] The working principle of the utility model is:

[0045] When trimming the aluminum casting, first insert the punch 5 that matches the shape of the part 16 into the punch slot 3 from left to right.

[0046] The two sides of the punch 5 are stepped, with the protruding part on the left side at the top and the concave part at the bottom.

[0047] The concave part of the right step is on the top and the protruding part is on the bottom.

[0048] When the two convex molds 5 are spliced, the protruding part of the left concave mold 5 cooperates with the concave part of the right concave mold 5.

[0049] The concave part of the left concave die 5 cooperates with the protruding part of the right concave die 5, and the plurality of convex dies 5 are spliced ​​by steps.

[0050] After the multiple convex molds 5 are tightly spliced, the part 16 is installed on the multiple convex molds 5, the body of the part 16 is placed on the boss 14 of the convex mold 5, and the ear wing 17 of the part 16 is sleeved on the positioning column 15 of the convex mold 5. After the convex mold 5 and the part 16 are installed, the die 9 is installed and the die 9 is installed into the die slide groove 7 from left to right. The multiple dies 9 are spliced ​​in a Z shape from left to right.

[0051] The two sides of the die 9 are stepped, with the protruding part of the left step at the bottom and the concave part at the top.

[0052] The right step has the protruding part on the top and the concave part on the bottom.

[0053] When the two dies 9 are joined, the protruding portion of the left die 9 cooperates with the concave portion of the right die 9.

[0054] The concave part of the left die 9 cooperates with the protruding part of the right die 9, and multiple die 9 are spliced ​​by steps.

[0055] After the die 9 is installed, the part 16 can be trimmed. At this time, the control button on the control box 6 is pressed, and the control box 6 sends an operation command to the cylinder 12. The cylinder rod 13 extends downward and moves. The cylinder rod 13 pushes the die chute 7 downward through the connecting plate 10. The die chute 7 slides downward on the slide bar 2. When sliding to the punch chute 3, the inner spacing of the die chute 7 is equal to the outer spacing of the punch chute 3. The die chute 7 overlaps with the punch chute 3. At this time, the cutting groove in the die 9 completes the trimming of the burrs on the ear wing 17 of the part 16. The trimming is stopped through the control box 6, and the stroke of the cylinder 12 is reset.
