Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 4 This utility model provides a technical solution:
[0027] An auxiliary device for preliminary processing of metal parts includes a base 1. A worktable 2 is fixedly connected to the upper end of the base 1. A striking assembly 3 is provided at both the front and rear ends of the worktable 2. Each striking assembly 3 includes cavities 31 formed at both the front and rear ends of the worktable 2. A fixed seat 32 is fixedly connected to the lower end of each cavity 31. A swing block 33 is movably connected to the upper end of the fixed seat 32. Rotating shafts 331 are fixedly connected to both the left and right ends of the swing block 33. A movable connection is established between the rotating shafts 331 and the fixed seat 32. The second spring 332, the front end of the swing block 33 is fixedly connected to the striking block 34, the upper end of the machine base 1 is fixedly connected to the slide rod 11 around the perimeter, the four slide rods 11 are movably connected to the outside of the first spring 111, the upper ends of the four slide rods 11 are movably connected to the sleeves 41, the upper ends of the multiple sleeves 41 are fixedly connected to the hydraulic press 4, the inside of the worktable 2 is provided with a square groove 21, and the square groove 21 extends to the lower end of the machine base 1, the upper end of the worktable 2 is fixedly connected to the front and rear sides of the upper end of the worktable 2 with guide plates 22.
[0028] By adopting the above technical solution, when bending metal parts is required, the metal blank is placed into the upper position of the square groove 21 along the two guide plates 22 on the upper end of the worktable 2 at the upper end of the machine base 1. The hydraulic press 4 is controlled to press down through the stop-start system. The downward movement of the hydraulic press 4 causes multiple sleeves 41 to continuously press down the first spring 111 through the slide rod 11. The downward movement of the hydraulic press 4 carries the lower pressure block 43 and the two racks 42 downward together. When the pressure block 43 moves downward, it squeezes and carries the metal parts that are in contact with the lower end of the pressure block 43 downward together. The part of the metal parts that is not in contact with the lower end of the pressure block 43 moves upward along the left and right sides of the pressure block 43. At the same time as the bending operation, the racks 42 move upward. The rack 42 moves downward and contacts the swing block 33. The teeth of the rack 42 carry the swing block 33 at the upper end of the fixed seat 32. By swinging downward with the pivot 331 as the fulcrum, the swing block 33 returns to the initial position under the elastic force of the second spring 332 after passing the teeth. The swing block 33 continuously contacts the teeth of the rack 42, causing the swing block 33 to swing up and down continuously. The continuous movement of the swing block 33 causes the striking block 34 to swing continuously. The striking block 34 continuously swings and strikes the front end of the cavity 31 to achieve a continuous striking effect. The striking generates vibration. Under the continuous vibration, the metal parts stuck inside the square groove 21 will fall down, thereby avoiding affecting the subsequent processing of the parts and thus affecting the processing of the entire metal parts.
[0029] Specifically, such as Figure 4 As shown, the lower end of the hydraulic press 4 is fixedly connected to a rack 42 and a pressure block 43, and there are two racks 42. The two racks 42 are located on the front and rear sides of the pressure block 43, and both racks 42 penetrate into the interior of the worktable 2. The interior of the worktable 2 has a storage groove 23 at both the front and rear ends. The two storage grooves 23 are each equipped with a pressing component 5. The pressing component 5 includes two third springs 51 movably connected to the front and rear ends of the storage groove 23. The ends of the two sets of third springs 51 that are close to each other are fixedly connected to a movable rod 52. The outside of the movable rod 52 is movably connected to a pressure roller 53. The lower end area of the pressure block 43 is smaller than the internal area of the square groove 21. The left and right ends of the pressure block 43 are inclined. The elastic force of the third spring 51 is greater than the sum of the weight of the pressure roller 53 and the movable rod 52. The pressure roller 53 slides against the interior of the storage groove 23.
[0030] By adopting the above technical solution, during the bending process of metal parts, the bending process will cause the bent metal parts to spring back due to the mechanical structure and material properties. The pressure block 43 moves downward and squeezes, carrying the metal parts that are in contact with the lower end of the pressure block 43 downward together. When the pressure block 43 carries the metal parts downward, and the metal parts at the left and right ends of the pressure block 43 pass through the receiving groove 23, the pressure roller 53 and the movable rod 52 and other components inside the receiving groove 23 are moved by the elastic force of the third spring 51. This causes the pressure roller 53 to move and carry the metal parts to the left and right ends of the pressure block 43 at an inclined slope, so that the left and right ends of the metal parts come closer to each other and squeeze, thereby achieving secondary squeezing of the metal parts and avoiding the springback of the metal parts, which would affect the quality of the metal parts.
[0031] Working principle: When bending metal parts is required, the metal blank is placed into the upper position of the square slot 21 along the two guide plates 22 on the upper end of the worktable 2 at the upper end of the machine base 1. The hydraulic press 4 is controlled by the stop-start system to press down. The downward movement of the hydraulic press 4 causes multiple sleeves 41 to continuously press down the first spring 111 through the slide rod 11. The downward movement of the hydraulic press 4 carries the lower pressure block 43 and the two racks 42 downward together. When the pressure block 43 moves downward, it squeezes and carries the metal parts that are in contact with the lower end of the pressure block 43 downward together. The part of the metal parts that is not in contact with the lower end of the pressure block 43 moves upward along the left and right sides of the pressure block 43. At the same time as the bending operation, the racks 42 move downward. The rack 42 teeth contact the swing block 33, and the swing block 33 at the upper end of the fixed seat 32 swings downward with the pivot 331 as the fulcrum. After passing the teeth, the swing block 33 returns to its initial position under the elastic force of the second spring 332. The swing block 33 continuously contacts the teeth of the rack 42, causing the swing block 33 to swing up and down continuously. The continuous movement of the swing block 33 causes the striking block 34 to swing continuously. The striking block 34 continuously swings and strikes the front end of the cavity 31 to achieve a continuous striking effect. The striking generates vibration. Under the continuous vibration, the metal parts stuck inside the square groove 21 will fall down, thereby avoiding affecting the subsequent processing of the parts and thus affecting the processing of the entire metal parts.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
