Description

Technical Field

[0001] This utility model relates to the field of stamping dies, and in particular to an adjustable scrap support arm assembly. Background Technology

[0002] In the mold structure of automotive exterior body panels, it is crucial that the scrap material cut from the sheet metal can fall smoothly out of the mold. To make the scrap material, especially that from the opposite side of the cutting blade, fall more easily, a bevel is set at the cutting blade. However, due to the force applied during stamping and cutting, the scrap material still tends to stick to the two cutting blades, and after bending, the elastic potential energy can sometimes cause it to get stuck between the two cutting blades, preventing it from falling out of the mold normally under its own weight.

[0003] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an adjustable waste material support arm assembly. This utility model is achieved through the following technical solution:

[0005] An adjustable waste material support arm assembly includes a support frame, on which a support arm is rotatably mounted. A pad is fixedly mounted at one end of the support arm, and a counterweight is detachably fixed at the other end. A limit post is also detachably fixed on the support frame.

[0006] In the above technical solution: the support frame is used to set up the other components; the stripping arm is used to form a lever; the pad is used to apply an upward force to the stuck waste; the counterweight is used to provide force; and the limiting post is used to limit the extreme angle of the stripping arm.

[0007] A further feature of this invention is that the support frame is provided with an installation groove, and the material support arm is rotatably disposed in the installation groove.

[0008] In the above technical solution, the installation groove reduces the left-right swaying of the material support arm and makes the structure more stable.

[0009] A further feature of this invention is that a connecting hole is fixedly provided in the middle of the material support arm, and a connecting bolt is provided in the connecting hole, so that the material support arm is rotatably connected to the support frame through the connecting bolt.

[0010] In the above technical solution: the connecting hole is used to install the connecting bolt; the connecting bolt is used to act as a rotating shaft.

[0011] A further feature of this invention is that the support frame is provided with a plurality of first mounting holes, and the connecting bolt passes through one of the first mounting holes and then through the connecting hole.

[0012] In the above technical solution: the first mounting hole is used to install connecting bolts.

[0013] A further feature of this invention is that a plurality of the first mounting holes are arranged in a vertical direction.

[0014] In the above technical solution, a number of first mounting holes are arranged vertically, which allows the position of the connecting bolts to be adjusted in different usage scenarios, thereby changing the limit position to which the pad can be lowered or raised.

[0015] A further feature of this invention is that the support frame is provided with a plurality of second mounting holes, and the limiting post is disposed in one of the second mounting holes.

[0016] In the above technical solution: the second mounting hole is used to set the limiting post.

[0017] A further feature of this invention is that a plurality of the second mounting holes are arranged in a vertical direction.

[0018] In the above technical solution: a number of second mounting holes are arranged vertically to change the position of the limiting post, so as to meet the limiting requirements of the stripper arm at different rotation positions.

[0019] This utility model discloses an adjustable waste material support arm assembly, which, compared with the prior art:

[0020] 1. This utility model, through the setting of support frame, material support arm and counterweight, enables the pad to be pressed down with the waste during stamping and cutting, and at the same time raises the counterweight to accumulate potential energy, so that when the stamping equipment separates, it can generate an upward pushing force on the waste, thereby preventing the waste from getting stuck, or lifting out the stuck material.

[0021] 2. By providing a number of first mounting holes and a number of second mounting holes, this utility model allows for adjustment of the rotation position of the material support arm in different practical scenarios, thereby adapting to different needs. It also allows for the setting of limit posts at different positions to achieve the limiting requirements at different positions. Attached Figure Description

A support arm 20 is rotatably mounted on the support frame 10. A pad 201 is fixedly mounted on one end of the support arm 20, and a counterweight 30 is detachably fixedly mounted on the other end. A limit post 40 is also detachably fixedly mounted on the support frame 10. The support frame 10 is T-shaped, and the support arm 20 is rotatably mounted on the vertical portion of the support frame 10. The horizontal portion of the support frame 10 is fixedly connected to a mounting platform such as a machine base.

[0029] like Figure 1 and 2 As shown, this utility model proposes an adjustable waste material support arm assembly. The support arm 20 has a connecting hole 202 fixedly provided in its middle. A connecting bolt 50 is installed in the connecting hole 202, and the support arm 20 is rotatably connected to the support frame 10 via the connecting bolt 50. Since excessive force is not required to avoid waste material being thrown away and causing safety issues, the distance between the connecting hole 202 and the counterweight 30 is less than the distance between the connecting hole 202 and the pad 201. The connecting bolt 50 and the connecting nut cooperate to achieve fixation.

[0030] like Figure 1 and 2As shown, this utility model proposes an adjustable waste material support arm assembly. The support frame 10 is provided with a plurality of first mounting holes 102. The connecting bolt 50 passes through one of the first mounting holes 102 and then through the connecting hole 202. The connecting bolt 50 does not have threads in the middle.

[0032] like Figure 1 and 2 As shown, this utility model proposes an adjustable waste material support arm assembly. The support frame 10 is provided with a plurality of second mounting holes 103, and the limiting post 40 is disposed in one of the second mounting holes 103. The diameter of the limiting post 40 is the same as the diameter of the second mounting hole 103.

[0033] like Figure 1 and 2 As shown, the present invention proposes an adjustable waste material support arm assembly, wherein a plurality of second mounting holes 103 are arranged in a vertical direction. Preferably, the number of second mounting holes 103 is three.

[0034] The working principle of this utility model is as follows:

[0035] a) Place the sheet metal on the mold, with the backing plate positioned below the sheet metal and between the two cutting blocks;

[0036] b) Stamping is performed using a stamping machine;

[0037] c) When the stamping die components cut the sheet metal;

[0038] d) The waste material is separated from the board and placed on the back of the two blades;

[0039] e) At this time, the pad plate of the stripper arm is pressed down along with the waste material, and the counterweight is raised;

[0040] f) After the stamping die components are separated from the scrap;

[0041] g) The counterweight descends under the influence of gravity, causing the pad to provide a thrust under the stuck waste material;

[0042] h) The waste material falls off the back of the blade under the action of the thrust.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
