Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile stamping processing, in particular to an automatic stamping forming device for aluminum profiles. Background Art

[0002] With the continuous development of today's society and the continuous progress of the machinery manufacturing industry, the scope of use of stamping equipment has gradually expanded. Stamping refers to a processing and forming method in which a press and a die are used to apply external force to plates, strips, pipes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining workpieces (stamping parts) of the desired shape and size. Many aluminum products are made by stamping. In the process of stamping aluminum profiles, due to the soft texture of the aluminum profile, it is easy to adhere to the surface of the upper die and then retreat, resulting in difficulty in demoulding and affecting continuous stamping operations. The contact surface between the existing demoulding rod and the aluminum profile is small, and grooves are easily formed on its contact surface during demoulding, affecting the quality of the stamped products. Utility Model Content

[0003] The purpose of the utility model is to provide an automatic stamping and forming device for aluminum profiles, which can quickly peel off the stamped aluminum profiles so that they are completely separated from the upper die seat for rapid demoulding operations, while not causing depressions on the contact surface with the aluminum profiles, thereby ensuring the quality of the stamped products.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic stamping forming device for aluminum profiles, comprising a base, a lower die base is fixedly connected at the top center of the base, a die groove is provided at the top center of the lower die base, a plurality of lifting cylinders are cross-symmetrically arranged on the top of the base, the lifting cylinders are arranged on the outside of the lower die base and the bottoms thereof are fixedly connected to the base, a top base is provided directly above the base, the top output ends of the lifting cylinders are fixedly connected to the top base, a hydraulic base is fixedly engaged with a hydraulic base at the top center of the top base, a plurality of hydraulic shafts are cross-symmetrically matched at the bottom of the hydraulic base, the bottom end of the hydraulic shaft extends out of the bottom of the top base and is fixedly connected to an upper die base, the upper part of the upper die base and the hydraulic shaft are all engaged and slidably connected to the top base, The upper die base is located directly above the lower die base, and a rectangular embedding groove is symmetrically arranged on the bottom of the upper die base, and an electric push rod is symmetrically arranged on the top of the rectangular embedding groove. The electric push rod is embedded and fixed in the inner wall of the upper die base, and a push plate is embedded in the inner side of the rectangular embedding groove. The outer side of the push plate is embedded and slides with the upper die base, and the bottom output end of the electric push rod is fixedly connected to the push plate. By cross-symmetrically arranging a number of electric push rods on the outer side of the bottom of the upper die base and respectively fitting the push plates to slide in the rectangular embedding groove, the push plate is synchronously pushed downward to peel off the stamped aluminum profile in the process of the upper die base returning after stamping, so that it is completely separated from the upper die base for rapid demoulding operation, and at the same time, it will not cause depression on the contact surface between it and the aluminum profile, thereby ensuring the quality of the stamped product.

[0005] In the automatic aluminum profile stamping and forming device, a sensor and a signal receiver are provided between the hydraulic seat and the electric push rod. When the hydraulic seat drives the hydraulic shaft to retract, the sensor transmits an electrical signal to the signal receiver, which controls the output end of the electric push rod to perform linear motion. The electric push rod is automatically controlled to perform a synchronous push-out motion in conjunction with the retraction motion of the hydraulic shaft, eliminating the need for manual operation.

[0006] According to the automatic stamping and forming device for aluminum profiles, the outer sides of the bottoms of the lifting cylinders are fixedly connected with positioning rings, and the bottoms of the positioning rings extend into the inner wall of the base and are fixedly connected thereto, thereby ensuring vertical stability between the lifting cylinders and the base.

[0007] According to the automatic stamping and forming device for aluminum profiles, a non-slip pad is fixed to the bottom of the base to ensure the stability of the entire device during stamping operations.

[0008] According to the automatic stamping and forming device for aluminum profiles, the outer corners of the base, top seat and the hydraulic seat thereon are all rounded to eliminate the corners and avoid certain injuries to the staff during operation.

[0009] According to the described automatic stamping and forming device for aluminum profiles, gasket rings are fixedly connected to the outer sides of the top output ends of the lifting cylinders, and the tops of the gasket rings are fixedly connected to the top seats. This improves the connection stability between the top seat and the output shaft of the lifting cylinder.

[0010] The beneficial effects of the above solution are:

[0011] In the present utility model, several electric push rods are symmetrically and crosswise embedded at the bottom outer side of the upper die base, and the push plates are respectively and slidably engaged with the rectangular slots on the left and right. During the process of the upper die base retracting after stamping, the push plates synchronously push downwards to peel off the stamped aluminum profiles, enabling them to completely separate from the upper die base for rapid demoulding operations. At the same time, it will not cause depressions on the contact surface with the aluminum profiles, ensuring the quality of the stamped products.
