Description

Technical Field

[0001] The present invention belongs to the field of geogrid processing and relates to a stamping die for geogrid processing. Background Art

[0002] A geogrid is a main geosynthetic material with good tensile strength and durability, and is widely used in fields such as road construction, slope protection, and foundation reinforcement to enhance soil stability and structural strength.

[0003] Plastic geogrids are the most common type of geogrids. During the processing, it is usually necessary to punch holes in the polymer sheet extruded, and then perform unidirectional or bidirectional stretching to form a polymer mesh material with a grid structure. Punching the polymer sheet requires the use of a stamping die. A Chinese patent discloses a stamping die for geogrid processing (publication number CN221793563U). The lower die is placed on the base, and the first through hole and the second through hole are aligned with each other. Rotating two first threaded rods causes the four clamping plates on the four sides of the lower die to move towards the side of the lower die to clamp the lower die, facilitating the fixation of lower dies of different sizes. After stamping, the second threaded rod is rotated by a forward and reverse motor to drive the lifting block and the lifting rod to move in the connecting pipe. After the lifting rod rises, it passes through the second through hole and the first through hole to eject the product located in the lower die, facilitating the taking out. However, the rotation of the two first threaded rods needs to be manually rotated by the operator respectively by turning the external handle, which is difficult to synchronize. The positioning of the lower die and the base needs to align the first through hole and the second through hole and then clamp and fix. The manual judgment of the hole alignment has errors, which may affect the subsequent penetration of the lifting rod. And after the lifting rod ejects part of the product, the operator needs to manually take out the product, and the operation is relatively cumbersome, with a high labor cost. Summary of the Invention

[0004] The purpose of the present invention is to provide a stamping die for geogrid processing with a high degree of automation in view of the above problems existing in the prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A stamping die for geogrid processing, comprising a base and a stamping assembly mounted on the base, characterized in that the base has an internal cavity and a lower die is placed on the top of the base, a positioning hole 1 is opened at the bottom of the lower die, a positioning hole 2 is opened in the middle of the top of the base, four positioning holes 1 and 2 are respectively arranged correspondingly, an electric clamping assembly and a positioning jacking assembly are arranged inside the base, the electric clamping assembly has four clamping plates, the four clamping plates are respectively located at the four sides of the lower die and under the drive of the electric clamping assembly, the four clamping plates have a tendency to move closer to the lower die and clamp and fix the lower die, the The positioning and lifting assembly includes a shell, a lifting cylinder, a lifting block and a lifting rod. The shell is fixedly connected below four positioning holes 2, the lifting cylinder is fixedly connected in the shell, the lifting block is fixedly connected to the end of the piston rod of the lifting cylinder, four lifting rods are arranged on the top of the lifting block, and the four lifting rods are arranged in a one-to-one correspondence with the four positioning holes 2. A pushing assembly is also arranged on the outside of one side of the base, and the pushing assembly includes an electric push rod and a push plate. The electric push rod is installed on the outside of one side of the base, and the push plate is fixedly connected to the end of the electric push rod. An upper mold is arranged at the bottom of the stamping assembly, and the upper mold is detachably connected to the stamping assembly.

[0007] The stamping die for local industrial grid processing realizes the automation of the whole process from lower die clamping to stamping and then to product demoulding and discharging through the cooperation of stamping components, electric clamping components, positioning and lifting components, and can adapt to the rapid clamping of lower dies of different sizes. The operation of each component can be controlled by an external controller. The specific usage is: when installing the lower die, the lifting block is driven upward by the lifting cylinder until the four lifting rods extend from two of the four positioning holes. By aligning the four positioning holes and putting them on the four lifting rods and placing the lower die on the base, the precise positioning of the installation position of the lower die is achieved, avoiding the possible errors in manual hole alignment, and then the four clamping plates are driven by the electric clamping component to move closer to the four sides of the lower die at the same time until the four clamping plates clamp the lower die tightly, so as to realize the automatic rapid clamping and positioning of lower dies of different sizes. After completion, the upper die and the lower die are aligned vertically, the lifting rod is retracted into the shell and the product to be punched is placed in the lower die, and the upper die is pressed downward by the stamping assembly to punch the product. During this process, the interval between the punching plate and the base can always accommodate the pushing assembly, and there is no conflict. After punching is completed, the upper die is first driven by the stamping assembly to move up and away from the lower die, and then the lifting rod is extended upward through positioning hole 1 and positioning hole 2 to push the product upward until the product is completely separated from the lower die. Since there are four lifting rods, the support stability of the product can be guaranteed in the process of four lifting rods lifting the product at the same time, and then the push plate is driven to approach the product by the electric push rod arranged on one side of the base until the push plate pushes the product out from the other side of the base, thereby realizing automatic demoulding and discharging of the punched product. It has a high degree of automation and convenient operation, reduces manual intervention, and thus reduces labor costs.

[0008] In the above-mentioned stamping die for geogrid processing, the stamping assembly includes a support rod, a support plate, a stamping cylinder and a punching plate. There are four support rods in a rectangular array on the top edge of the base. The support plate is fixedly connected to the top of the four support rods. The stamping cylinder is installed in the middle of the top of the support plate and the stamping rod of the stamping cylinder extends downward from the support plate and is fixedly connected to the punching plate. The upper mold is connected in the middle of the bottom of the punching plate.

[0009] The four support rods stably support the support plate, so that sufficient working space is formed between the support plate and the base, and the support plate provides a stable connection platform for the stamping cylinder. The operation of the stamping cylinder can drive the punch plate connected to the stamping rod of the stamping cylinder to descend or ascend. When the punch plate descends, the upper die punches the product placed on the lower die to complete the punching process. The punch plate rises and the upper die moves away from the lower die, which is convenient for the demoulding and discharge of subsequent products.

[0010] In the above-mentioned stamping mold for geogrid processing, the electric clamping assembly includes a forward and reverse motor, a bidirectional screw and a clamping plate. There are two forward and reverse motors and two bidirectional screws respectively, and there are four clamping plates. The two bidirectional screws are cross-arranged in the base and the two bidirectional screws are rotatably connected to the base. The two forward and reverse motors are respectively arranged on the outside of the adjacent two sides of the base and the two forward and reverse motors are respectively connected to the two bidirectional screws for transmission. The two sections of the thread of the bidirectional screw are in opposite directions, and each bidirectional screw is threadedly connected to two clamping plates and the two clamping plates are respectively connected to the two sections of the thread of the bidirectional screw. Four sliding grooves are opened on the top of the base, and the four sliding grooves are respectively opposite to each section of the thread of the two bidirectional screws up and down, and the four clamping plates are respectively slidably connected to the four sliding grooves.

[0011] Two bidirectional screws are driven to rotate simultaneously by two forward and reverse motors. Since the two sections of the thread of each bidirectional screw are in opposite directions, the two clamps threaded on each bidirectional screw are symmetrically connected to the threads at both ends. Under the limitation of the clamps on the slide groove, the two clamps on each bidirectional screw can move in relative or opposite directions, so that the four clamps can move inward or outward synchronously. When the four clamps move inward, they move closer to and clamp the lower mold, and when the four clamps move outward, they move away from and release the lower mold, which is convenient for quick replacement and clamping of lower molds of different sizes.

[0012] In the above-mentioned stamping die for geogrid processing, a plurality of mounting holes are opened in the middle of the stamping plate, and the plurality of mounting holes are distributed in a circular array around the stamping rod of the stamping cylinder, and the upper die is connected to the plurality of mounting holes through fasteners.

[0013] The arrangement of several mounting holes facilitates the fastening connection and disassembly of the upper die and the punch plate. The upper die is fixed to the bottom of the punch plate by fasteners (such as bolts) passing through the mounting holes, ensuring that the upper die is in a centered position while facilitating maintenance or replacement of the upper die.

[0014] In the above-mentioned stamping die for geogrid processing, four sliding holes are formed at the edge of the punching plate. The four sliding holes are arranged corresponding to the four support rods one by one, and the four sliding holes are respectively slidably connected to the four support rods.

[0015] The arrangement of the four sliding holes enables the punching plate to be slidably connected to the four support rods. The support rods play a guiding role for the punching plate, ensuring the moving stability of the punching plate when the punching cylinder drives the punching plate to rise or fall, so that the punching plate always moves in the vertical direction, and further improving the accuracy of stamping.

[0016] In the above-mentioned stamping die for geogrid processing, a height adjustment assembly is arranged outside one side of the base. The height adjustment assembly includes a mounting seat, an electric screw rod and a slider. The mounting seat is fixedly connected to the outside of one side of the base. An installation groove is formed inside the mounting seat. The electric screw rod is rotatably connected in the installation groove. The slider is threadedly connected to the electric screw rod and is slidably connected to the installation groove. The electric push rod is connected to the slider.

[0017] The height adjustment assembly can adjust the height of the push plate within a certain range to flexibly adapt to the pushing work of products with different thicknesses. The mounting seat is used to ensure the connection stability. When the electric screw rod rotates, it can drive the slider to move up and down in the installation groove, thereby driving the electric push rod and the push plate to move up and down, realizing the adjustment of the height position of the push plate.

[0018] In the above-mentioned stamping die for geogrid processing, the lifting block matches the inner side wall of the shell, and the outer side wall of the lifting block is slidably connected to the inner side wall of the shell.

[0019] When the lifting cylinder drives the lifting block to perform a lifting motion, the lifting block slides relative to the shell, so that the lifting block always moves in the vertical direction, ensuring that the four lifting rods are always aligned with the four positioning holes one and the four positioning holes two, and further ensuring the operation of positioning the lower die and ejecting the product.

[0020] In the above-mentioned stamping die for geogrid processing, the length of the lifting rod is greater than the distance between the top of the lower die and the top of the shell.

[0021] The lifting rod can completely eject the product in the lower die until it is separated from the lower die, which helps the product to be demolded and also facilitates the subsequent pushing component to push out the product.

[0022] Compared with the prior art, the stamping die for local industrial grille processing has a high degree of automation. Through the coordinated operation of the electric clamping component, stamping component, positioning and lifting component, and material pushing component, the whole process of automation operation from clamping in the lower die to stamping and then to product demoulding and discharging is realized. There is no need to manually take out the stamped product, which is convenient to operate, reduces manual intervention, and lowers the labor cost. The electric clamping component can adapt to the clamping of lower dies of different sizes, with a wide range of applications. The positioning and lifting component can not only be used to lift the product completed by stamping in the lower die, but also help with the positioning between the lower die and the base during the clamping of the lower die, improving the positioning accuracy, avoiding the error of manual alignment, and further enhancing the accuracy of subsequent stamping work.
