Description

Technical Field

[0001] This utility model relates to a high-speed trimming device for stamped and drawn parts, belonging to the field of trimming technology for drawn parts. Background Technology

[0002] Currently, for stamped and drawn parts, due to the irregular material flow and the need to ensure product requirements, a trimming process is often used to straighten the four sides of the product. Currently, rotary cutting dies are mostly used for trimming the product. In existing technology, rotary cutting dies use wedges, guide rails, etc. to punch two opposite sides of the product. The trimming method using wedges and guide rails in existing technology is affected by wedge wear and impact, which means that its rotary cutting speed generally does not exceed 50PPM.

[0003] For the current market demand, especially in the new energy industry, the required stamped and drawn parts products are produced in large batches with high requirements. The cutting speed of the trimming method using wedges and guide rails cannot meet the actual needs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-speed trimming device for stamped and drawn parts.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes:

[0006] This utility model embodiment provides a high-speed trimming device for stamped and drawn parts, including:

[0007] A feeding mechanism, which is at least used to drive the stretching member to the shearing position;

[0008] A shearing mechanism is provided, wherein a shearing opening is provided on the shearing mechanism and the shearing position is located in the shearing opening. The shearing mechanism is used at least for shearing in a direction perpendicular to the side of the stretching member.

[0009] Furthermore, the shearing mechanism includes a shearing base, a shearing die, and a driving assembly. The shearing opening is formed on the shearing base. The shearing die has the same number of cutting edges as the side of the stretched member and corresponding positions, and the cutting edges surround the inner wall of the shearing opening. The driving assembly is at least used to drive the cutting edges of the shearing die to move in a direction perpendicular to the side of the stretched member.

[0010] Furthermore, the driving assembly includes a cam and several driving blocks. The cam is rotatably disposed on one side of the shearing base, and the several driving blocks are connected to the end face of the cam. The driving blocks are disposed on the shearing die, and the cam is used to drive the driving blocks to move in a direction perpendicular to the side of the stretching member by rotation.

[0011] Furthermore, the shearing mechanism also includes a guide seat, which is disposed on the shearing base. The shearing opening passes through the guide seat, and the guide seat has guide channels inside which are the same number and position as the driving blocks. The driving blocks are placed in the guide channels.

[0012] Furthermore, a support plate is provided at the bottom of the shearing opening. When the stretching member moves to the shearing position, the support plate is used to at least support the bottom of the stretching member and help stabilize the stretching member.

[0013] Furthermore, the feeding mechanism includes an adjusting block, a cylinder, and several clamping blocks. The clamping blocks are disposed at the ends of the adjusting block, and the cylinder is used to drive the clamping blocks to extend outwards from the adjusting block and abut against the inner wall of the stretching member.

[0014] Furthermore, the adjusting block is provided with several adsorption holes. When the end of the adjusting block contacts the bottom surface of the stretching member, the adsorption holes are used to adsorb the stretching member onto the adjusting block.

[0015] Furthermore, the feeding mechanism also includes a wedge and a guide block. The wedge is connected to the cylinder and the guide block respectively. The wedge is used to drive the guide block to move at the end of the adjusting block. The guide block is connected to the clamping block. The guide block is used to drive the clamping block to extend outwards to the periphery of the adjusting block.

[0016] Furthermore, the feeding device also includes a feeding drive, which is at least used to move the adjusting block to the shearing position.

[0017] Furthermore, the adjusting block is also provided with a fixed inner blade and a movable inner blade, the movable inner blade being sandwiched between the adjusting block and the fixed inner blade, and the movable inner blade being used at least for shearing along a direction perpendicular to the side of the stretching member.

[0018] Compared with the prior art, the advantages of this utility model include:

[0019] 1. This utility model uses a shearing mechanism that moves along a direction perpendicular to the side of the stretched part and shears the stretched part, which can effectively reduce the impact and wear on the stretched part, thereby increasing the rotary cutting speed of the stretched part and thus improving production efficiency.

[0020] 2. The shearing mechanism of this utility model uses a cam-driven shearing die to shear the stretched parts. Compared with the use of wedge shearing, it can generate less impact and wear, thereby increasing the upper limit of the rotary cutting speed.

[0021] 3. When the feeding mechanism drives the stretching part into the shearing port, the suction hole at the end of the adjusting block of the feeding mechanism can form a negative pressure on the bottom surface of the stretching part, adsorbing the stretching part and ensuring the stability of the stretching part during movement and shearing.

[0032] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0033] Example 1

[0034] like Figures 1-5 The first embodiment of the present invention shows a high-speed trimming device for stamped and drawn parts, comprising a feeding mechanism 1 for driving the drawn part 20 to the shearing position; and a shearing mechanism 2 with a shearing opening 3, the shearing position being located in the shearing opening 3. The shearing mechanism 2 is used to shear along a direction perpendicular to the side surface of the drawn part 20. In this embodiment, the drawn part 20 is a solid formed by stretching a rectangular ring and has a bottom surface at one end in the stretching direction. That is, the feeding mechanism 1 drives the drawn part 20 into the shearing opening 3 along the stretching direction and places it in the shearing position, and then the shearing mechanism 2 shears along a direction perpendicular to the four side surfaces of the drawn part 20 to achieve trimming of the drawn part 20.

[0035] The shearing mechanism 2 of this embodiment includes a shearing base 4, a shearing die 5, and a drive assembly 6. The shearing die 5 is disposed inside the shearing base 4, and the shearing opening 3 is specifically disposed on the shearing machine base. The shearing die 5 has cutting edges corresponding to the four sides of the stretched member 20, and the cutting edges are disposed around the inner wall of the shearing opening 3. The drive assembly 6 drives the shearing die 5 to move in four directions perpendicular to the sides of the stretched member 20, and shears and trims the stretched member 20. The drive assembly 6 of this embodiment consists of a cam 7 and two drive blocks 8. One end of each drive block 8 is rotatably disposed on the two end faces of the cam 7, and the other end of each drive block 8 is rotatably disposed on the shearing die 5. The drive blocks 8 are rotatably disposed at a position offset from the rotation axis of the cam 7, so that when the cam 7 rotates, it will drive the drive blocks 8 to move, and the drive blocks 8 will also rotate relative to the cam 7, and at the same time drive the shearing die 5 to move, so that the shearing die 5 moves and shears and trims the stretched member 20.

[0036] When the drive assembly 6 drives the shearing die 5 to move, the direction of movement of the shearing die 5 needs to be restricted so that the shearing die 5 can shear along the direction perpendicular to the four sides of the stretching member 20. Therefore, in this embodiment, a guide seat 9 is added to the shearing mechanism 2, and the guide seat 9 is set on the shearing base 4. The guide seat 9 is penetrated by the shearing opening 3. The guide seat 9 is provided with mutually perpendicular guide channels inside, and the four directions extended by the two mutually perpendicular guide channels are perpendicular to the four sides of the stretching member 20 respectively. Two drive blocks 8 are respectively set in the two guide channels. Therefore, when the cam 7 drives the drive block 8 to move, the drive block 8 will move along the extension direction of the guide channel, thereby ensuring that the two drive blocks 8 drive the shearing die 5 to move along the direction perpendicular to the four sides of the stretching member 20, so as to realize the shearing and trimming of the stretching member 20.

[0037] Example 2

[0038] like Figure 6 The second embodiment of this utility model is shown. The structure of the high-speed trimming device for stamped and drawn parts in this embodiment is basically the same as that in embodiment 1. The difference from embodiment 1 is that the feeding mechanism 1 in this embodiment includes an adjusting block 11, a cylinder 12, four clamping blocks 13, a wedge 15, and a guide block 16. The four clamping blocks 13 are disposed at the ends of the adjusting block 11, specifically on the end face of the adjusting block. The wedge 15 is connected to the guide block 16 and the cylinder 12 respectively. The cylinder 12 drives the wedge to move perpendicular to the end face of the adjusting block, and drives the guide block 16 to move on the end face of the adjusting block. Through the guide block 16, the clamping blocks 13 extend out to the periphery of the adjusting block 11 and abut against the inner wall of the drawn part 20. That is to say, when the drawn part 20 reaches a suitable position for shearing... When the position is reached, the wedge 15 extends in a direction perpendicular to the end face of the adjusting block 11. At this time, the wedge 15 will drive the guide block 16 to move along the end face of the adjusting block 11. The movement of the guide block 16 will drive the four clamping blocks 13 to extend around the adjusting block 11 until all four clamping blocks 13 abut against the inner wall of the stretching member 20, thus completing the limiting and fixing of the stretching member 20 before shearing. The adjusting block 11 is also provided with several suction holes 14. When the end of the adjusting block 11 contacts the inner bottom surface of the stretching member 20, the suction holes 14 are used to suction the stretching member 20 onto the adjusting block 11. The feeding device also includes a feeding drive 17. Under the drive of the feeding drive 17, the adjusting block 11 drives the stretching member 20 fixed on the adjusting block 11 to move to the shearing position for shearing and trimming.

[0039] Example 3

[0040] like Figure 7 one Figure 8The third embodiment of the present invention shown in this embodiment has a structure that is basically the same as that of the high-speed trimming device for stamped and stretched parts. The difference from the first embodiment is that the bottom of the shearing port 3 in this embodiment is provided with a bottom support plate 10, and a spring is provided between the bottom support plate 10 and the bottom of the shearing port 3. When the stretched part 20 moves to the shearing position under the drive of the adjusting block 11, the bottom support plate 10 is used to support the outer bottom surface of the stretched part 20 and assist in stabilizing the stretched part 20. It also works with the feeding mechanism 1 to fix the stretched part 20 between the inner bottom surface and the outer bottom surface, so that the stretched part 20 can be stably trimmed.

[0041] Furthermore, the adjusting block 11 is also equipped with a fixed inner blade 18 and a movable inner blade 19. The movable inner blade 19 is sandwiched between the adjusting block 11 and the fixed inner blade 18. The movable inner blade 19 is connected to the vertically moving drive block 8. When the cam 7 drives the drive block 8 to move vertically, the drive block 8 will drive the movable inner blade 19 to shear in a direction perpendicular to the side of the stretching member 20. The shearing direction of the movable inner blade 19 is opposite to the shearing direction of the shearing die 5. That is, when the shearing die 5 extends to the side of the stretching member 20, the movable inner blade 19 retracts in a direction perpendicular to the side of the stretching member 20. At this time, the shearing die 5 performs the first shearing on the side of the stretching member 20. When the shearing die 5 retracts to the side of the stretching member 20, the movable inner blade 19 extends in a direction perpendicular to the side of the stretching member 20. At this time, the movable inner blade 19 performs the second shearing on the side of the stretching member 20 to ensure the shearing efficiency of the stretching member 20.

[0042] It should be understood that the above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
