Description

Technical Field

[0001] This application relates to the field of material processing technology, and in particular to a dual-motor feeding mechanism. Background Technology

[0002] Currently, the material processing of steel strip by stamping refers to applying pressure to the steel strip using stamping equipment and dies to cause it to undergo plastic deformation or separation, thereby obtaining parts or products of the required shape and size.

[0003] During processing, select steel strips of appropriate material and thickness, ensuring their surface is clean and free of defects. Design molds according to product requirements, determine the stamping shape, and use equipment such as punch presses or presses to apply pressure to the steel strip through the mold. Under the action of the mold, the steel strip undergoes plastic deformation or separation to form the desired shape.

[0004] During the processing of steel strip, a driving force is required to continuously pass through the stamping equipment so that the stamping equipment can continuously stamp the steel strip.

[0005] Regarding the aforementioned technologies, the inventors believe that when the steel strip passes through the stamping equipment, the end portion of the steel strip loses its driving force, resulting in waste at the end portion of the steel strip. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a dual-motor feeding mechanism, which solves the technical problem that when the steel strip passes through the stamping equipment, the end part of the steel strip loses driving force, resulting in waste of the end part of the steel strip.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A dual-motor feeding mechanism includes: a frame for supporting the feeding mechanism; a press body with an upper die holder and a lower die holder, through which a steel strip passes; and a drive unit mounted on the frame and spaced apart on both sides of the press body for driving the steel strip.

[0009] Furthermore, the frame is provided with a guide rail, which is installed on the side of the frame close to the press body. A guide groove is formed in the guide rail, and the guide groove communicates with the press body.

[0010] Furthermore, a pressure groove is provided on the guide rail, the pressure groove is connected to the guide groove, a support block is provided on the guide rail, a pressure block is provided on the support block, the pressure block passes through the pressure groove, and a compression spring is provided between the pressure block and the support block, the compression spring abuts against the pressure block and the support block.

[0011] Furthermore, the driving component includes a drive motor, on which a rotating disk is mounted, and a positioning rod is provided on the rotating disk. Several positioning rods are spaced apart on the rotating disk, and positioning holes are provided on the steel strip, with several positioning holes spaced apart along the steel strip.

[0012] Furthermore, a lifting cylinder is provided on the frame, the lifting cylinder is vertically arranged, and the drive motor is mounted on the piston rod of the lifting cylinder.

[0013] Furthermore, a positioning block is provided on the frame, a positioning pin is provided on the positioning block, and a support spring is provided between the positioning pin and the positioning block, with the support spring pressing against the positioning block and the positioning pin.

[0014] Furthermore, a pressure plate and a clamping cylinder are provided on one side of the stamping machine body. The clamping cylinder is vertically arranged, and the pressure plate is installed on the piston rod of the clamping cylinder. The pressure plate is spaced apart from the stamping machine body.

[0015] In summary, this application includes at least the following beneficial technical effects of a dual-motor feeding mechanism:

[0016] The steel strip is passed between the upper and lower die bases, and the press body punches the steel strip. During the punching process, the drive components on both sides of the press body drive the steel strip alternately to prevent the end of the steel strip from losing driving force when it passes through the punching equipment, thereby reducing waste at the end of the steel strip during processing.

[0017] By setting up guide rails and guide grooves, as well as pressure blocks and clamping springs, the stability of the steel strip being conveyed on the guide rails is improved.

[0018] The lifting cylinder drives the drive motor for lifting, and the setting of positioning pins and support springs improves the ease of engagement between the rotating disc and the steel belt. Attached Figure Description

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a dual-motor feeding mechanism.

[0027] Reference Figure 1 The dual-motor feeding mechanism includes a frame 1, on which a stamping machine body 2 is mounted. Drive units 3 are located on both sides of the stamping machine body 2. A steel strip passes through the stamping machine body 2, and the drive units 3 continuously drive the steel strip through the stamping machine body 2. The two sets of drive units 3 drive the steel strip, ensuring that the tail end of the steel strip is also partially stamped by the stamping machine body 2.

[0028] The stamping machine body 2 includes an upper die holder 21 and a lower die holder 22. An inlet 23 is formed on one side of the upper die holder 21 and the lower die holder 22, and an outlet 24 is formed on the other side. The steel strip enters from one side of the inlet 23, and after being stamped by the upper die holder 21 and the lower die holder 22, the steel strip is sent out from the outlet 24.

[0029] Reference Figures 2-3 A guide rail 11 is provided on the side of the frame 1 near the feed inlet 23 of the press body 2. A guide groove 12 is formed on the guide rail 11 and is connected to the feed inlet 23. During use, the steel strip passes through the guide groove 12 of the guide rail 11. To improve the stability of the steel strip moving on the guide rail 11, pressure grooves are formed on both sides of the guide rail 11 at the guide groove 12. The pressure grooves are perpendicular to the guide rail 11 and are connected to the guide groove 12.

[0030] Reference Figure 3Furthermore, a support block 13 is provided on the guide rail 11, which corresponds to the pressure groove. A pressure block 131 is provided on the support block 13, which is embedded in the pressure groove. A compression spring 132 is provided between the pressure block 131 and the support block 13, with both ends of the compression spring 132 connected to the pressure block 131 and the support block 13, respectively. When the steel strip passes through the guide groove 12 of the guide rail 11, the compression spring 132 presses the pressure block 131 against the steel strip, thereby improving the stability of the steel strip moving on the guide rail 11.

[0031] To improve the ease of movement of the steel strip on the guide rail 11, the drive component 3 includes a drive motor 31, which is slidably mounted on the frame 1. A rotating disk 32 is mounted on the output shaft of the drive motor 31. Two rotating disks 32 are spaced apart on the drive motor 31, and each rotating disk 32 is equipped with a positioning rod 33. Several positioning rods 33 are evenly spaced around the axis of the rotating disk 32. In use, positioning holes 34 are opened on both sides of the steel strip in the width direction, and several positioning holes 34 are evenly spaced along the length direction of the steel strip. During use, the drive motor 31 drives the rotating disks 32 to rotate, and the positioning rods 33 on the rotating disks 32 engage with the positioning holes 34 on the steel strip. As the rotating disks 32 rotate, the steel strip continuously passes through the stamping machine body 2.

[0032] In use, the drive unit 3 on the side of the stamping machine body 2 near the feed port 23 drives the steel strip forward. When the steel strip comes into contact with the drive unit 3 on the side of the stamping machine body 2 near the discharge port 24, the drive unit 3 on the side of the stamping machine body 2 near the feed port 23 stops working. At the same time, the drive unit 3 on the side of the stamping machine body 2 near the discharge port 24 starts working. By alternately conveying the steel strip with the two drive units 3, the waste of steel at the tail of the steel strip can be reduced and the stamping effect of the steel strip can be improved.

[0033] To improve the ease of alternation between the steel belt drive components 3, a lifting cylinder 35 is installed on the frame 1. The lifting cylinder 35 is vertically mounted on the frame 1 and corresponds to the two sets of drive components 3. The piston rods of both lifting cylinders 35 are connected to the drive motor 31. In use, the lifting cylinder 35 drives the drive cylinders of the two sets of drive components 3 to move up and down. When the drive motor 31 descends, the positioning rod 33 on the rotating disk 32 separates from the positioning hole 34 on the steel belt. When the drive motor 31 rises, the positioning rod 33 on the rotating disk 32 engages with the positioning hole 34 on the steel belt. This improves the ease of alternation between the two sets of drive components 3.

[0034] When the steel strip is fed into the guide groove 12 of the guide rail 11, a positioning block 14 is provided on the frame 1 to improve the ease of engagement between the positioning rod 33 on the rotating disk 32 and the steel strip. The positioning block 14 is mounted on the guide rail 11, and a positioning pin 141 is provided on the positioning block 14. The positioning pin 141 is slidably mounted on the positioning block 14. A support spring 142 is provided between the positioning pin 141 and the positioning block 14. The support spring 142 is sleeved on the positioning pin 141, with one end of the support spring 142 pressing against the positioning pin 141 and the other end pressing against the positioning block 14. In use, the steel strip is inserted from one end of the guide rail 11, and then the positioning pin 141 is pressed down. At this time, the support spring 142 is compressed. When the positioning pin 141 passes through the positioning hole 34 of the steel strip, the positioning rod 33 on the rotating disk 32 also passes through the positioning hole 34 of the steel strip.

[0035] Reference Figure 4 After the steel strip is stamped by the press body 2, in order to prevent one end of the steel strip from curling up, a clamping cylinder 15 is provided on the side of the frame 1 near the discharge port 24 of the press body 2. The clamping cylinder 15 is vertically arranged, and a pressure plate 151 is provided on the piston rod of the clamping cylinder 15. The pressure plate 151 is spaced apart from the frame 1. When in use, the processed steel strip passes through the pressure block 131 and the frame 1, and the steel strip is clamped by the pressure block 131, thereby preventing the end of the steel strip from curling up when it is output.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
