Description

TECHNICAL FIELD

[0002] In the traditional automobile reinforcing plate support stamping device, the commonly used ejection structure is the design that the ejection rod directly penetrates the receiving lower die. When the stamping is completed, the ejection rod is upwardly ejected to assist the finished product to separate from the die. However, the penetrating type ejection rod structure has many disadvantages. In the ejection process, the gap between the ejection rod and the receiving lower die is easy to cause the automobile reinforcing plate support finished product to be scratched when demolding, because the edge or surface of the finished product can be in contact with the edge of the gap, resulting in surface scratches, burrs and other quality problems, which seriously affect the appearance and subsequent use performance of the product. Moreover, in the long-term use process, due to the frequent ejection pressure and friction with the finished product, the die material around the gap is easy to be worn and deformed, thereby reducing the overall structural strength of the receiving lower die. Once the structural strength is damaged, the precision and stability of the die will be affected, resulting in the increase of the size deviation of the stamped automobile reinforcing plate support, the shape not meeting the requirements and other quality defects, at the same time, the service life of the die is also shortened, the cost and frequency of die maintenance and replacement are increased, the production efficiency is reduced and the production cost is increased, which is not conducive to the efficient and high-quality production operation of automobile parts manufacturing enterprises.

[0022] The utility model will be further described in detail in combination with examples:

[0023] Example 1

[0024] As Figures 1-4 The utility model provides a kind of stamping device of automobile reinforcing plate support, including stamping equipment frame 1 and cylinder 2, stamping equipment frame 1 inner wall top is provided with cylinder 2, the bottom surface of cylinder 2 is fixedly connected with pressing upper die 3, pressing upper die 3 below is provided with the butt joint of its adaptation receiving lower die 4;

[0025] Receiving lower die 4 outer wall is movably connected with the lower die positioning plate 5 for its positioning, the upper surface of lower die positioning plate 5 is provided with receiving groove 6, and the inner wall of receiving groove 6 is movably connected with the outer wall of receiving lower die 4.

[0026] The bottom surface of receiving lower die 4 is fixedly connected with ejector spring rod 7, the bottom surface of ejector spring rod 7 is fixedly connected with the support horizontal plate 8 for supporting it, and the bottom surface of pressing upper die 3 is provided with leveling assembly, and the leveling assembly is used to press and level the automobile reinforcing plate support raw material.

[0027] The top end of ejector spring rod 7 is movably penetrated into the inside of receiving groove 6, and the two ends of support horizontal plate 8 are fixedly connected with the inner wall of stamping equipment frame 1.

[0028] Example 2

[0029] As Figures 1-4 Indicated in the embodiment, on the basis of the utility model provides a kind of technical scheme: preferably, leveling assembly includes flattening roller 11, and the two ends of flattening roller 11 are rotatably connected with pressing bottom bar 10, and one end of pressing bottom bar 10 away from oblique spring rod 13 is rotatably connected with one side of pressing upper die 3, and one side of pressing bottom bar 10 is fixedly connected with return spring 14, and one end of return spring 14 away from pressing bottom bar 10 is fixedly connected with mounting block 12, and mounting block 12 is fixedly connected to one side of pressing upper die 3.

[0030] The number of flattening roller 11 is two.

[0031] The upper surface of the lower die positioning plate 5 is fixedly connected with a positioning post 9, and the bottom surface of the lower die positioning plate 5 is fixedly connected to the bottom of the inner wall of the stamping equipment frame 1.

[0032] The working principle of the stamping device for the car reinforcement bracket will be explained in detail below.

[0033] like Figures 1-4 As shown, during use, the raw material is placed on the receiving lower die 4, and the edges and corners of the raw material are positioned by the positioning pin 9. Then, the power is turned on to start the cylinder 2, which pushes the pressure upper die 3 down to perform stamping. After stamping is completed, as the cylinder 2 drives the pressure upper die 3 to move upward, the pressure on the receiving lower die 4 gradually decreases, and it will begin to move upward under the reaction force of the ejector spring rod 7. At the same time, it will drive the stamped automotive reinforcement plate bracket to move upward as a whole until its lowest structure is out of the range of the receiving groove 6, thus facilitating the subsequent removal of the automotive reinforcement plate bracket.

[0034] The ejector spring rod 7 ejects the entire lower mold 4, which avoids the impact of the gap caused by the ejector spring rod 7 penetrating the lower mold 4 on the finished automotive reinforcement bracket, and also ensures the overall structural strength of the lower mold 4.

[0035] The positioning pins 9 are arranged in pairs, with the four sets of positioning pins 9 distributed at the four diagonal positions of the receiving lower mold 4. This allows the raw material to be positioned during placement, preventing the problem of the raw material's position being affected when the receiving lower mold 4 is ejected.

[0036] After the raw material is placed, during the process of lowering the upper pressure die 3 in preparation for stamping, as the upper pressure die 3 moves downward, the flattening roller 11 first contacts the surface of the raw material. Since the bottom pressure rod 10 is obliquely distributed, it begins to deflect to the side of the upper pressure die 3 under the thrust of the downward movement of the upper pressure die 3. During the movement of the flattening roller 11, the oblique spring rod 13 and the return spring 14 are compressed. With the help of the reaction force of the two, the flattening roller 11 can apply a certain pressure to the surface of the raw material, so that the raw material can fit tightly with the receiving lower die 4 before pressing. When the flattening roller 11 leaves the upper surface area of ​​the receiving lower die 4, the bottom surface of the upper pressure die 3 will then come close to the receiving lower die 4. After the cylinder 2 drives the upper pressure die 3 to the initial position, the flattening roller 11 does not contact the surface of the receiving lower die 4.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
