Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive stamping parts flanging technology, and in particular to an automotive stamping parts flanging device. Background Technology
[0002] Flanging refers to a forming method in which a die is used to create a straight wall or flange at a certain angle on the flat or curved part of a blank. It is a stamping method that uses the material's positional deformation to turn the blank into a vertical edge along a certain curve on a pre-machined hole or part of the hole shape (sometimes without pre-machined holes). It is divided into round hole flanging and outer edge flanging. Most of the metal parts of automobiles are produced using stamping flanging technology.
[0003] Currently, when stamping and flanging automotive parts, the flanging angle is usually determined by the tilt angle between the punch and the contact surface of the workpiece. If the flanging angle needs to be changed and expanded outward, the punch needs to be replaced, which will undoubtedly increase production costs and reduce production efficiency. Therefore, we propose an automotive stamping part flanging device. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when stamping and flanging automotive parts, the flanging angle is usually determined by the inclination angle between the punch and the contact surface of the workpiece. If the flanging angle needs to be changed and expanded outward, the punch needs to be replaced, which undoubtedly increases production costs and reduces production efficiency.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] An automotive stamping part flanging device includes a base, and a stamping mechanism is mounted on the top of the base;
[0007] The base has a square slot near the left side of its top. Inside the square slot, near the right side, is a built-in groove. A push plate is rotatably connected inside the built-in groove near the left side. Several guide rails are installed at equal intervals from front to back on the right side of the push plate and inside the built-in groove. A motor with its output end facing left is installed inside the base near the right side. A drive assembly is installed at the output end of the motor. A base plate is installed inside the built-in groove and above the drive assembly. Several first push rods are welded to the top of the base plate and abutting against the inside of the guide rails. A second push rod is welded to the right side of each of the first push rods.
[0008] As a preferred embodiment of this utility model, the stamping mechanism includes a support frame, which is installed on the top of the base. A first hydraulic cylinder and a second hydraulic cylinder are installed sequentially from left to right on the top of the support frame. The output end of the first hydraulic cylinder extends to the bottom of the support frame and is equipped with a punch. The output end of the second hydraulic cylinder extends to the bottom of the support frame and is equipped with a pressure plate.
[0009] The technical effect of adopting the above-mentioned further solution is that the first hydraulic cylinder can drive the punch to move up and down, thereby stamping and flanging the automobile workpiece placed on the top of the base. The second hydraulic cylinder can drive the pressure plate to move up and down, thereby causing the pressure plate to fit with the automobile workpiece, achieving the purpose of fixing before stamping, preventing displacement of the automobile workpiece, and improving the stability of use.
[0010] As a preferred embodiment of this utility model, a first limiting rod is symmetrically installed on the top of the punch near the front and back, and a second limiting rod is symmetrically installed on the top of the pressure plate near the front and back. Both the first limiting rod and the second limiting rod are slidably connected to the support frame.
[0011] The technical effect of adopting the above-mentioned further solution is that the first limit rod and the second limit rod can respectively limit the punch and the pressure plate, preventing them from deviating during movement and improving the stability of use.
[0012] As a preferred embodiment of this utility model, the drive assembly includes a lead screw, which is rotatably connected inside the base. The lead screw is fixedly connected to the output end of the motor, and a slider is sleeved around the lead screw.
[0013] The technical effect of adopting the above-mentioned further solution is that the motor can drive the lead screw to rotate, thereby causing the lead screw to drive the base plate and the first and second push rods above it to move left and right through the slider, so as to push the push plate and improve the ease of use.
[0014] As a preferred embodiment of this utility model, the base plate is welded to the slider, and limit blocks are symmetrically welded to the bottom of the base plate near the front and back sides, and the limit blocks are slidably connected to the base.
[0015] The technical effect of adopting the above-mentioned further solution is that the limiting block can limit the movement of the base plate, prevent it from shifting during the movement, and improve the stability of use.
[0016] As a preferred embodiment of this utility model, the left end of the first push rod that abuts against the inside of the guide rail is a smooth metal sphere structure.
[0017] The technical effect of adopting the above-mentioned further solution is that the metal spherical structure can reduce friction, slide better inside the guide rail, and improve the smoothness of use.
[0018] As a preferred embodiment of this utility model, the top end of the second push rod is a metal sphere structure.
[0019] The technical effect of adopting the above-mentioned further solution is that the second push rod can take over from the first push rod to continue pushing the push plate when the push plate is pushed out at too large an angle, thereby improving the stability of use.
[0020] As a preferred embodiment of this utility model, adjustable feet are installed at the bottom of the base near the four corners.
[0021] The technical effect of adopting the above-mentioned further solution is that the height of the base can be adjusted to be level by adjusting the feet, thus improving practicality.
[0022] Compared with the prior art, the beneficial effects of this utility model are:
[0023] In this invention, through the design of the base and the stamping mechanism, the extension of the second hydraulic cylinder drives the pressure plate to fix the car workpiece placed above the base. The first hydraulic cylinder drives the punch to perform a 90-degree stamping and flanging of the car workpiece. When it is necessary to change the stamping angle, the punch is retracted, and the motor drives the lead screw to rotate, causing the slider to push the push plate through the first push rod and the second push rod on the base plate, causing the push plate to flip to the left, thereby pushing the car workpiece to the left with a 90-degree flanging, achieving the purpose of modifying the flanging angle. There is no need to replace the punch, which greatly reduces the production cost and effectively improves the production efficiency. Attached Figure Description

[0033] Example 1
[0034] like Figure 1-4As shown, this utility model provides a technical solution: a flanging device for automotive stamping parts, including a base 1, a stamping mechanism 2 installed at the top of the base 1, a square groove 101 opened near the left side of the top of the base 1, an internal groove 102 opened near the right side of the square groove 101, a push plate 103 rotatably connected to the internal groove 102 near the left side, a plurality of guide rails 104 are installed at equal intervals from front to back on the right side of the push plate 103 and inside the internal groove 102, a motor 105 with its output end facing left is installed near the right side of the base 1, a drive assembly 106 is installed at the output end of the motor 105, a base plate 107 is installed inside the internal groove 102 and at the top of the drive assembly 106, a plurality of first push rods 108 are welded to the top of the base plate 107 and abutting against the internal of the guide rails 104, and a second push rod 109 is welded to the right side of the first push rods 108.
[0035] Example 2
[0036] like Figure 1-4As shown, the stamping mechanism 2 includes a support frame 201, which is mounted on the top of the base 1. From left to right, a first hydraulic cylinder 202 and a second hydraulic cylinder 203 are sequentially mounted on the top of the support frame 201. The output end of the first hydraulic cylinder 202 extends to the bottom of the support frame 201 and is equipped with a punch 204. The output end of the second hydraulic cylinder 203 extends to the bottom of the support frame 201 and is equipped with a pressure plate 205. The first hydraulic cylinder 202 can drive the punch 204 to move up and down, thereby stamping and flanging the automotive workpiece placed on the top of the base 1. The second hydraulic cylinder 203 can drive the pressure plate 205 to move up and down, thereby moving the pressure plate 205 against the base 1. The automotive workpiece is fitted together to achieve the purpose of fixing it before stamping, preventing displacement of the automotive workpiece and improving the stability of use. A first limiting rod 2041 is symmetrically installed on the top of the punch 204 near the front and back, and a second limiting rod 2051 is symmetrically installed on the top of the pressure plate 205 near the front and back. Both the first limiting rod 2041 and the second limiting rod 2051 are slidably connected to the support frame 201. The first limiting rod 2041 and the second limiting rod 2051 can respectively limit the punch 204 and the pressure plate 205, preventing them from shifting during movement and improving the stability of use. The drive assembly 106 includes a lead screw 1061, which is rotatably connected to... Inside the base 1, a lead screw 1061 is fixedly connected to the output end of a motor 105. A slider 1062 is fitted around the lead screw 1061. The motor 105 can drive the lead screw 1061 to rotate, thereby causing the lead screw 1061 to drive the base plate 107 and the first push rod 108 and the second push rod 109 above it to move left and right through the slider 1062, thus pushing the push plate 103 and improving ease of use. The base plate 107 is welded to the slider 1062. Limiting blocks 1071 are symmetrically welded to the bottom of the base plate 107 near the front and back. The limiting blocks 1071 are slidably connected to the base 1, and the moving base plate 107 can be limited by the limiting blocks 1071. To prevent deviation during movement and improve stability, the left end of the first push rod 108, which abuts against the inside of the guide rail 104, is a smooth metal ball structure. This metal ball structure reduces friction and allows for better sliding within the guide rail 104, improving smoothness of use. The top of the second push rod 109 is also a metal ball structure. When the push plate 103 is pushed out at too large an angle, the second push rod 109 can take over from the first push rod 108 to continue pushing the push plate 103, improving stability. Adjustable feet 110 are installed at the bottom of the base 1 near the four corners. By adjusting the feet 110, the height of the base 1 can be adjusted to be level, improving practicality.
[0037] The working process of this utility model is as follows: When using an automotive stamping part flanging device to adjust the angle of automotive workpiece stamping and flanging, the automotive workpiece is first placed on the top of the base 1. The extension of the second hydraulic cylinder 203 drives the pressure plate 205 to fix the automotive workpiece placed on the base 1. The first hydraulic cylinder 202 drives the punch 204 to perform 90-degree stamping and flanging on the automotive workpiece. Then, the retraction of the first hydraulic cylinder 202 retracts the punch 204. The motor 105 drives the lead screw 1061 to rotate, causing the lead screw 1061 to drive the base plate 107 to move to the left through the slider 1062. This causes the first push rod 108 to push the push plate 103, causing the push plate 103 to flip to the left and push the flanging of the automotive workpiece, thereby achieving the purpose of adjusting and expanding the stamping and flanging angle. There is no need to replace the punch 204, which greatly reduces production costs and effectively improves production efficiency.
