Detailed Description
The present invention will be described with reference to specific embodiments.
Fig. 1 is a front view of the trimming and shaping device of the present invention, and fig. 4 is a top view of a lower mold, as shown in fig. 1 and 4. Deburring shaping device sets up on mould 1 for processing work piece 4, mould 1 includes: the lower die 2 and an upper die 3 which is connected with the lower die 2 in a sliding way. The lower die 2 is provided with a working plate 21, and the top of the working plate 21 is connected with a shaping mechanism 24 in a sliding manner. The shaping mechanism 24 includes: the shaping blocks 241 are symmetrically arranged on two sides of the working plate 21, and the inner side surfaces of the shaping blocks 241 are connected with the sliding blocks 242 of the shaping blocks 241. The shaping block 241 is semi-cylindrical, and a semicircular shaping groove 2411 is formed in the end face of the shaping block 241.
As shown in fig. 1, after the machining, the upper die 3 moves upward, the workpiece remains in place, the slider 242 moves along the working plate 21 toward the workpiece 4 until the shaping blocks 241 on both sides contact, at this time, due to the semicircular arrangement, the two semicircles are recombined into a complete circle, the groove surface of the shaping groove 2411 contacts with the outer surface of the workpiece, the secondary extrusion further shapes the outer part of the workpiece, and fixes the shape of the workpiece 4 generated after the stamping.
As shown in fig. 1, the height of the slider 242 is greater than the height of the shaped block 241, and the top surfaces of the shaped block 241 and the slider 242 coincide. When the two shaping blocks 241 are contacted, a certain space is reserved below for the flanging of the workpiece 4 to pass through, otherwise, the workpiece is clamped or even damaged due to collision.
The height difference between the sliding block 242 and the shaping block 241 is equal to the flanging height of the workpiece 4. By utilizing the height difference and the jointing of the flanging, when the shaping block 241 moves towards the cylindrical surface of the workpiece 4, the lower surface of the shaping block 241 is used for removing some burrs on the flanging, thereby achieving two purposes.
Fig. 2 is a partial view a of fig. 1, and fig. 3 is a partial enlarged view B of fig. 2, as shown in fig. 2 and 3. The bottom surface of the upper die 3 is connected with a working cylinder 32, and the bottom of the working cylinder 32 is provided with a wedge-shaped cutter 321. The inner side surface of the working cylinder 32 is provided with a side plate 322, and the side plate 322 is parallel to the working plate 21.
The cylinder 311 operates to drive the working cylinder 32 to press down, and the lower surface of the abutting block 33 arranged in the working cylinder 32 is attached to the upper surface of the processing column 23, so that punching is completed. Meanwhile, the workpiece 4 is extruded and formed by the side plate 322 of the working cylinder 32 by utilizing the principle that the diameter of the lower end of the abutting block 33 is smaller than the outlet of the working cylinder 32. The flange is formed by press molding from the lower surface of the cylinder 32. On this basis, set up wedge-shaped cutter 321, it is harder in the material, utilize cutter 321 sectional area to be less than the working cylinder 32 lower surface, the principle that extrusion pressure is bigger, amputate turn-ups unnecessary deckle edge. And also facilitates further shaping afterwards.
Fig. 5 is a schematic view of the slide rail assembly, as shown in fig. 5. The two side edges of the top surface of the working plate 21 are symmetrically provided with sliding grooves 211. The sliding block 242 is in a shape of a Chinese character 'tu', and the sliding block 242 is slidably connected with the sliding groove 211. The convex shape fixes the connection relationship between the sliding block 242 and the sliding groove 211 by using a structure with a larger lower part and a smaller upper part, so as to prevent the sliding block 242 from being separated.
In this embodiment, the workpiece 4 is placed on the surface of the working plate 21, the air cylinder 311 drives the upper die 3 to move downward, and the guide post 34 fixed on the top surface of the lower die 2 and the guide cylinder fixed on the bottom surface of the upper die 3 are combined to perform a guiding function. In this process, the external: the lower surface of the cutter 321 of the working cylinder 32 is provided with the working plate 21, the working plate 21 is pressed downwards, the supporting column 22 below the working plate 21 moves downwards at the moment, and the supporting spring 221 is compressed; inside: the processing column 23 perpendicular to the working plate 21 and connected with the working plate 21 in a sliding manner is contacted with the work resisting block 33, the resisting block 33 in the working cylinder 32 overcomes the thrust spring 331 to do work, moves upwards, and the thrust spring 331 is compressed.
The workpiece 4 is stamped and the process is reversed. After the upper die 3 leaves, the sliding block 242 slides to push the shaping block 241 to move towards the workpiece 4 until the shaping blocks 241 at the two sides contact, the inner shaping grooves 2411 are combined into a whole circle, and the groove surfaces of the shaping grooves 2411 are attached to the cylindrical surface of the workpiece for shaping.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
