Description

Technical Field

[0001] The present invention relates to the field of machinery, in particular to progressive dies, and more particularly to a material supporting mechanism for a progressive die. Background Art

[0002] A progressive die is a multi-station stamping die that realizes the forming of complex parts through step-by-step processing and can complete multiple processes simultaneously. For example, a progressive die can simultaneously complete multiple processes such as trimming, punching, and bending. In the prior art, during the production process of a progressive die, due to the long strip of material, the middle part of the strip is prone to sink during transportation, resulting in the strip not being accurately and smoothly transported to the predetermined positions of each station in the die, seriously affecting the continuity of production and the stability of product quality.

[0003] In order to solve the problem of unsmooth feeding caused by material sinking, in the prior art, a cylinder is installed below the area where the material needs to pass. When the cylinder operates, it lifts the material to ensure that the material can be smoothly pushed by the feeding mechanism to the correct position of the next station, and then the piston rod of the cylinder retracts and stamping is performed.

[0004] However, the above solution relies on special electronic control equipment and requires an external air source and electronic control system to control the cylinder, which not only increases the equipment occupation space and maintenance frequency but also increases the production cost. Summary of the Invention

[0005] The purpose of the present invention is to provide a material supporting mechanism for a progressive die to solve the technical problems in the prior art that the material discharging mechanism not only increases the equipment occupation space and maintenance frequency but also increases the production cost.

[0006] The present invention provides a material supporting mechanism for a progressive die, which includes a lower slider guide seat. A lower slider is arranged on the lower slider guide seat. The lower slider and the lower slider guide seat form a sliding pair parallel to the front-rear direction. A material supporting frame is fixedly connected to the front end of the lower slider. An obliquely through hole penetrating up and down is arranged in the lower slider. The axial direction of the obliquely through hole forms an angle with the vertical direction of the lower slider. A first inclined surface and a second inclined surface are respectively arranged on the front side and the rear side of the obliquely through hole. The first inclined surface is parallel to the second inclined surface. A through hole penetrating up and down is arranged in the lower slider guide seat. An upper driving block is inserted into the through hole and the obliquely through hole. The extending direction of the lower section of the upper driving block forms an angle with the extending directions of the upper section and the middle section of the upper driving block. A third inclined surface and a fourth inclined surface are respectively arranged on the front side and the rear side of the lower section of the upper driving block. The third inclined surface cooperates with the first inclined surface, and the fourth inclined surface cooperates with the second inclined surface.

[0007] Further, a slide rail is arranged on the lower slider guide seat, and the lower slider is arranged on the slide rail.

[0008] Further, a fixed plate is fixedly arranged on the lower slider guide seat behind the lower slider. A spring is arranged between the fixed plate and the lower slider, and the spring biases the lower slider forward.

[0009] Compared with the prior art, the effects of the present invention are positive and obvious. The present invention adopts the cooperation and linkage of the upper die base and the upper driving block. The upper driving block drives the material supporting frame to move through the lower slider, thus replacing the air cylinder, eliminating the need for an external air source and an electric control system, reducing the occupied space of the equipment, the maintenance frequency, and the production cost.

[0012] The present invention will be further described below in conjunction with embodiments, but the present invention is not limited to these embodiments. Any similar changes made using the present invention should be included in the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, middle, inside, and outside in the present invention is only for the convenience of clear description and does not limit the technical solution of the present invention.

[0013] As Figure 1 - Figure 2 shown, the present invention provides a continuous die material supporting mechanism, including a lower slider guide seat 1. A lower slider 2 is arranged on the lower slider guide seat 1. The lower slider 2 and the lower slider guide seat 1 form a sliding pair parallel to the front-back direction. The front end of the lower slider 2 is fixedly connected with a material supporting frame 3. An obliquely through hole 4 is arranged through the upper and lower parts of the lower slider 2. The axial direction of the obliquely through hole 4 forms an angle with the vertical direction of the lower slider 2. A first inclined surface 5 and a second inclined surface 6 are respectively arranged on the front side and the rear side of the obliquely through hole 4. The first inclined surface 5 is parallel to the second inclined surface 6. A through hole 7 is arranged through the upper and lower parts of the lower slider guide seat 1. An upper driving block 8 is arranged through the through hole 7 and the obliquely through hole 4. The extending direction of the lower segment of the upper driving block 8 forms an angle with the extending directions of the upper segment and the middle segment of the upper driving block 8. A third inclined surface 10 and a fourth inclined surface 11 are respectively arranged on the front side and the rear side of the lower segment of the upper driving block 8. The third inclined surface 10 cooperates with the first inclined surface 5, and the fourth inclined surface 11 cooperates with the second inclined surface 6.

[0014] Further, a slide rail is arranged on the lower slider guide seat 1, and the lower slider 2 is arranged on the slide rail.

[0015] Further, a fixed plate 12 is fixedly arranged on the lower slider guide seat 1 behind the lower slider 2. A spring 13 is arranged between the fixed plate 12 and the lower slider 2, and the spring 13 biases the lower slider 2 forward.

[0016] Working principle of the present invention: The upper driving block 8 is fixed to the upper die base of the progressive die. The overall operation process of the progressive die is that stamping and feeding are carried out alternately. When the upper die base moves downward, stamping is performed; when the upper die base moves upward, feeding is performed. When the progressive die performs the stamping action, the upper die base drives the upper driving block 8 to move downward through the inclined through hole 4 of the lower sliding block 2 and the through hole 7 of the lower sliding block guide seat 1. The fourth inclined surface 11 of the upper driving block 8 cooperates with the second inclined surface 6 of the lower sliding block 2, thereby pushing the lower sliding block 2 to move backward to Figure 1 the state shown, and at the same time, the lower sliding block 2 drives the stock support 3 to move backward and away from the lower part of the strip, completing one stamping action. After the stamping action is completed, the feeding and conveying action is carried out. The upper die base drives the upper driving block 8 to move upward. The third inclined surface 10 of the upper driving block 8 cooperates with the first inclined surface 5 of the lower sliding block 2, thereby pushing the lower sliding block 2 to move forward. At the same time, the lower sliding block 2 drives the stock support 3 to move forward to the lower part of the strip. The stock support 3 supports the strip, enabling the strip to be smoothly fed and conveyed.

[0017] The present invention adopts the cooperation and linkage of the upper die base and the upper driving block 8. The upper driving block 8 drives the stock support 3 to move through the lower sliding block 2, thus replacing the cylinder, eliminating the need for an external air source and electric control system, and reducing the equipment occupation space, maintenance frequency and production cost.

[0018] The function of the spring 13 is to push the lower sliding block 2 forward to a more accurate position after the upper driving block 8 moves upward, so that the upper driving block 8 can more accurately move downward through the inclined through hole 4 of the lower sliding block 2.
