Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal rolling processing equipment, specifically a stretching machine for non-ferrous metal rolling processing. Background Technology

[0002] Stretching machines are key equipment used for the stretching and processing of metal sheets. They thin or shape metal sheets by applying tension. However, traditional stretching machines have two main problems in the processing: First, it is difficult to position the metal sheet, which requires repeated manual adjustments, affecting processing efficiency; second, the sheet is subjected to uneven stress during stretching, which can easily lead to inconsistent thickness around the finished product, affecting product quality.

[0003] Publication number CN222902307U discloses a stretching machine for processing non-ferrous metal rolled materials, which employs a limiting mechanism in conjunction with a scale design. This design includes two symmetrically distributed first and second thin rods, connected by a rotating joint to form an adjustable positioning structure. The scale allows operators to visually determine the position of the metal sheet, achieving rapid positioning and ensuring uniform force distribution around the sheet during processing.

[0004] However, when a material is stretched, some micro-cracks will appear on its surface, which will reduce the corrosion resistance of the material after stretching.

[0005] Therefore, a stretching machine for processing non-ferrous metal rolled materials is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a stretching machine for processing non-ferrous metal rolled materials, which can solve the problems mentioned in the background art.

[0008] Preferably, the middle of the rotating shaft is sleeved with the middle of the outer part of the upper clamp.

[0009] Preferably, both the upper clamp and the pulling clamp are equipped with an electric telescopic rod at one end.

[0010] Preferably, the slider and the rotating shaft are fixedly connected.

[0011] Preferably, the rotating shaft and the rack are fixedly connected, and the sawtooth structure of the rack meshes with the sawtooth structure of the gear.

[0018] 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. Example

[0019] A stretching machine for processing non-ferrous metal rolled materials includes a drive base 1, a housing 5 is provided at the upper end of the drive base 1, a pulling clamp 3 is provided at the middle of the bottom of the housing 5, and an upper clamp 8 is provided at the middle of the upper end of the inner side of the housing 5. The front of the housing 5 is provided with outer frames 4 on both sides. The lower end of the inner side of the outer frame 4 is provided with a piston cylinder 10. The lower end of the front of the piston cylinder 10 is provided with a suction pipe 11. The upper end of the front of the piston cylinder 10 is provided with a nozzle 9. The other end of the suction pipe 11 is provided with a liquid cylinder 2. The piston cylinder 10 is vertically provided with a piston rod 19. The top of the piston rod 19 is provided with a spool 18. The upper end of the spool 18 is provided with a connecting rod 20. The top of the connecting rod 20 is provided with a slider 17. The spool 18 is vertically provided through the inner side of the slider 17. A spring 7 is sleeved on the outside of the spool 18. The bottom of the spool 18 is provided with a limit part 15. A rack 16 is provided on one side of the slider 17, a rotating shaft 13 is provided at the bottom of one side of the slider 17, a gear 14 is provided on one side of the rack 16, a crank arm 6 is provided on the back of the gear 14, and a wiping plate 12 is provided on the back of the crank arm 6.

[0020] Example 1: Please refer to Figure 1 - Figure 5 The upper end of the drive base 1 is provided with a housing 5, the bottom of the housing 5 is provided with a pulling clamp 3, and the upper end is provided with an upper clamp 8. Both are connected to an electric telescopic rod, which drives the material to move up and down to stretch the material. The material is clamped between the pulling clamp 3 and the upper clamp 8, and the processing efficiency is improved by bidirectional stretching. The front of the housing 5 is provided with outer frames 4 on both sides. The lower end of the inner side of the outer frame 4 is provided with a piston cylinder 10. The piston cylinder 10 is connected to the liquid cylinder 2 through the suction tube 11 for storing anti-corrosion liquid. The top of the piston rod 19 is fixed with a spool 18. The spool 18 is connected to the slider 17 through the connecting rod 20. The slider 17 slides on the spool 18. The spring 7 assists in the reset. The limiting part 15 prevents excessive movement. When the slider 17 moves, it drives the piston rod 19 to reciprocate in the piston cylinder 10 to realize the suction and spraying of anti-corrosion liquid and protect the surface of the stretched material. The slider 17 is fixedly connected to the rotating shaft 13. The rotating shaft 13 drives the rack 16 to move. The rack 16 meshes with the gear 14. The gear 14 drives the crank arm 6 to swing. The crank arm 6 drives the wiping plate 12 to move along the material surface to remove impurities. The width of the wiping plate 12 is greater than the width of the fixture to ensure thorough cleaning. The electric telescopic rod can be replaced with a lead screw mechanism driven by a servo motor to improve the stretching accuracy, and the piston cylinder 10 can be replaced with a solenoid valve to control the liquid flow and achieve quantitative spraying.

[0021] Example 2: Please refer to Figure 1 - Figure 5 The inner side of the housing 5 is provided with a rotating shaft 13, which is fixedly connected to the slider 17 and the rack 16. When the upper clamp 8 moves, it drives the rotating shaft 13 to rise and fall. The rack 16 drives the gear 14 to rotate. The gear 14 controls the wiping plate 12 to wipe the material surface through the crank arm 6. The piston cylinder 10 and the liquid cylinder 2 are connected through the suction pipe 11. The reciprocating motion of the piston rod 19 realizes liquid spraying. The spool 18 is fixedly connected to the connecting rod 20 to ensure that the slider 17 and the piston rod 19 move synchronously. The wiping plate 12 is made of flexible material to avoid scratching the material. The rack 16 and gear 14 can be replaced with synchronous belt drive to reduce wear. The liquid cylinder 2 is equipped with a filter to prevent impurities from clogging the nozzle 9.

[0022] In use, the user clamps the material between the pulling clamp 3 and the upper clamp 8. Since one end of the pulling clamp 3 and the upper clamp 8 are connected to an electric telescopic rod, one of the electric telescopic rods drives the pulling clamp 3 to move downward, and the other electric telescopic rod drives the upper clamp 8 to move upward. The upper clamp 8 drives the rotating shaft 13 to move upward, and the rotating shaft 13 drives the slider 17 to move. The slider 17 moves outside the spool 18. The spring 7 helps the slider 17 to reset, and the limiting part 15 prevents the slider 17 from moving excessively. When the slider 17 moves, it will drive the connecting rod 20 to move. The connecting rod 20 drives the piston rod 19 to move inside the piston cylinder 10. The suction tube 11 outside the piston cylinder 10 absorbs the anti-corrosion liquid inside the liquid cylinder 2. When the piston rod 19 moves with the spool 18 again, the liquid inside the liquid cylinder 2 is sprayed out from the piston cylinder 10 onto the surface of the material being pulled, so as to ensure that the finished product formed after the material is stretched will not be damaged by the corrosive liquid. When the slider 17 moves with the rotating shaft 13, the rotating shaft 13 drives the rack 16 to move, the rack 16 drives the gear 14 to rotate, and the gear 14 drives the crank arm 6 to move along the vertical edge of the housing 5. The crank arm 6 will then drive the wiping plate 12 to wipe the surface of the stretched material and keep the material surface clean.

[0023] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
