Description

Technical Field

[0001] This utility model relates to the field of saw blade production technology, specifically a cold pressing device for saw blade production and processing. Background Technology

[0002] A saw blade is a type of steel blade with a cutting edge similar to a handsaw. It is a general term for thin, round cutting tools used to cut solid materials. Currently, most saw blade manufacturing equipment involves direct stamping, which easily leads to uneven surfaces on the saw blades during production, thus greatly reducing the quality of the saw blades. Patents have been developed to address this issue.

[0003] Chinese patent CN216324522U discloses a cold pressing device for saw blade production and processing, including a base. A U-shaped frame is provided at the top center of the base. One end of the U-shaped frame is fixedly connected to the top surface of the base. A support platform is vertically connected to the inner wall of one side of the U-shaped frame. The other end of the support platform is fixedly connected to the bottom of the other end of the U-shaped frame. The bottom of the other end of the support platform is connected to the top of the base through a support leg. A first pressing cylinder is fixedly connected at the top center of the U-shaped frame. An installation cylinder is provided below the first pressing cylinder. The installation cylinder is coaxially installed at the bottom of the first pressing cylinder. A support plate is coaxially installed at the bottom of the installation cylinder. The bottom of the support plate is coaxially connected to a first pressure plate. The edge of the first pressure plate has several saw teeth. Each saw tooth contains a matching saw tooth punch head, which not only improves the quality of saw blade processing but also improves the efficiency of saw blade processing.

[0004] The aforementioned patent requires controlling multiple pressing cylinders to drive multiple pressure plates to press the saw blade downwards during the saw blade stamping process. This involves controlling the cylinders sequentially to cold-press the saw blade through multiple steps, which is overly cumbersome and results in low efficiency in the cold-pressing process. Furthermore, since the saw blade is placed manually, it is easy for it to become skewed, which is difficult to detect. This can cause the saw blade to be out of center, resulting in irregular stamping of the surface teeth and affecting its subsequent use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cold pressing device for saw blade production and processing. It solves the problem that controlling the hydraulic cylinders to cold press the saw blade in multiple steps is too cumbersome and prone to causing deviations that are difficult to detect, resulting in the saw blade not being in the center position and causing irregular punching of the saw blade's surface teeth.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cold pressing device for saw blade production and processing, comprising a support base and a fixed frame fixedly connected to the top of the support base. A saw tooth support plate is fixedly connected to the top of the support base. A first hydraulic telescopic rod is fixedly connected to the top of the fixed frame through an opening. A fixed plate is fixedly connected to the telescopic end of the first hydraulic telescopic rod. A plurality of sliding rods are slidably connected to the top of the fixed plate through an opening. A saw tooth limiting plate is fixedly connected to one end of each sliding rod. A baffle plate is fixedly connected to the other end of each sliding rod. A stamping column is fixedly connected to the bottom of the fixed plate. A circular opening adapted to the stamping column is provided on the top of both the saw tooth support plate and the saw tooth limiting plate. A plurality of connecting rods are fixedly connected to the surface of the fixed plate. A saw tooth stamping plate is fixedly connected to one end of each connecting rod.

[0007] Preferably, mounting plates are fixedly connected to all four sides of the top of the support base. A limit rod is slidably connected to the side of the mounting plate away from the sawtooth support plate through an opening. A lower inclined panel is fixedly connected to one end of the limit rod. A spring is sleeved on the surface of the limit rod between the mounting plate and the lower inclined panel.

[0008] Preferably, a second hydraulic telescopic rod is fixedly connected to one side of the top of the support base through an opening, and an annular plate is fixedly connected to the telescopic end of the second hydraulic telescopic rod.

[0009] Preferably, the top of the annular plate is fixedly connected with several upper inclined panels that are adapted to the lower inclined panel.

[0010] Preferably, the top of the support base has several sliding openings that are adapted to the upper inclined panel.

[0011] Preferably, the top of the support base has a discharge port adapted to the circular opening, and the top of the support base has several discharge ports.

[0012] Beneficial effects

[0013] This utility model provides a cold pressing device for saw blade production and processing. Compared with the existing technology, it has the following advantages:

[0014] (1) This utility model controls the first hydraulic telescopic rod to drive the fixed plate to move downward. The fixed plate will drive the saw tooth limiting plate, the stamping column and the saw tooth stamping plate to move downward. The saw tooth limiting plate and the stamping column will first contact the saw blade. Then, the first hydraulic telescopic rod will continue to drive the fixed plate to move downward. The fixed plate will drive the stamping column and the saw tooth stamping plate to stamp the saw blade. The saw tooth limiting plate will continue to stick to the saw blade to limit it, ensuring that the saw blade is stamped more evenly. The saw blade is stamped and formed by the stamping column and the saw tooth stamping plate. Only the first hydraulic telescopic rod needs to be controlled to cold press the saw blade, which is more convenient to operate and improves the efficiency of cold pressing of the saw blade.

[0015] (2) This utility model controls the second hydraulic telescopic rod to retract and drive the ring plate to move upward. The ring plate drives multiple upper inclined panels to move upward and squeeze multiple lower inclined panels, pushing multiple lower inclined panels to move towards the middle. Multiple lower inclined panels will drive multiple limit rods to move towards the middle at the same time. Multiple limit rods will push the saw blade on the saw tooth support plate to the center position for limit, which can well ensure that the saw blade is in the center position for cold pressing, and ensure the quality of saw blade cold pressing.

[0022] Please see Figure 1-4This utility model provides a technical solution: a cold pressing device for saw blade production and processing, including a support base 1 and a fixed frame 2 fixedly connected to the top of the support base 1. A saw tooth support plate 3 is fixedly connected to the top of the support base 1. A first hydraulic telescopic rod 4 is fixedly connected to the top of the fixed frame 2 through an opening. The first hydraulic telescopic rod 4 is controlled by a control switch. A fixed plate 5 is fixedly connected to the telescopic end of the first hydraulic telescopic rod 4. A plurality of sliding rods 6 are slidably connected to the top of the fixed plate 5 through an opening. A serrated limiting plate 7 is fixedly connected to one end of the sliding rod 6. The surfaces of the serrated support plate 3 and the serrated limiting plate 7 are provided with several serrated heads. A baffle plate 22 is fixedly connected to the other end of the sliding rod 6. A stamping column 8 is fixedly connected to the bottom of the fixed plate 5. A circular opening 9 that matches the stamping column 8 is opened on the top of the serrated support plate 3 and the serrated limiting plate 7. Several connecting rods 10 are fixedly connected to the surface of the fixed plate 5. A serrated stamping plate 11 is fixedly connected to one end of the several connecting rods 10. Several serrated heads are provided on the inner surface of the serrated stamping plate 11.

[0023] Furthermore, to facilitate the adjustment and centering of the saw blade, mounting plates 12 are fixedly connected to all four sides of the top of the support base 1. A limit rod 13 is slidably connected to the side of the mounting plate 12 away from the saw tooth support plate 3 through an opening. A lower inclined plate 14 is fixedly connected to one end of the limit rod 13. A spring 15 is sleeved on the surface of the limit rod 13 between the mounting plate 12 and the lower inclined plate 14. A second hydraulic telescopic rod 16 is fixedly connected to one side of the top of the support base 1 through an opening. The second hydraulic telescopic rod 16 is controlled by a control switch. An annular plate 17 is fixedly connected to the telescopic end of the second hydraulic telescopic rod 16. Several upper inclined plates 18 that are adapted to the lower inclined plate 14 are fixedly connected to the top of the annular plate 17.

[0024] It should be noted that by moving the four limit rods 13 to the center at the same time and adjusting the position of the saw blade until the ends of the four limit rods 13 contact the saw blade at the same time, the saw blade can be located at the center of the saw tooth support plate 3.

[0025] Furthermore, in order to facilitate the falling of the scrap material stamped by the stamping column 8, the top of the support base 1 is provided with several sliding openings 19 that are adapted to the upper inclined panel 18.

[0026] Furthermore, in order to facilitate the falling of the scrap material stamped by the serrated stamping plate 11, the top of the support base 1 is provided with a discharge port 20 that matches the circular opening 9, and the top of the support base 1 is provided with several discharge ports 21.

[0027] It should be noted that a collection box is placed below the support base 1 to collect the scrap material produced by the saw blade.

[0028] In use, the saw blade is placed on the saw tooth support plate 3. By controlling the second hydraulic telescopic rod 16 to retract, the ring plate 17 is moved upward. The ring plate 17 will drive multiple upper inclined panels 18 to move upward. The multiple upper inclined panels 18 will press multiple lower inclined panels 14 upward, pushing the multiple lower inclined panels 14 to move towards the center at the same time. The multiple lower inclined panels 14 will drive multiple limiting rods 13 to move towards the center, so that the multiple limiting rods 13 push the saw blade on the saw tooth support plate 3 and limit the saw blade on the saw tooth support plate 3 to the center.

[0029] The first hydraulic telescopic rod 4 is extended to drive the fixed plate 5 to move downward. The fixed plate 5 will drive the saw tooth limiting plate 7 and the saw tooth stamping plate 11 to move downward through the sliding rod 6 and the connecting rod 10. The saw tooth limiting plate 7 and the stamping column 8 on the fixed plate 5 will first contact the saw blade downward. The stamping column 8 will squeeze and limit the saw blade. Then, the second hydraulic telescopic rod 16 is extended to drive the multiple upper inclined panels 18 to move downward and no longer squeeze the lower inclined panel 14. The spring 15 will drive the limiting rod 13 to move outward so that the multiple limiting rods 13 no longer contact the saw blade.

[0030] Then, control the first hydraulic telescopic rod 4 to extend and continue to drive the fixed plate 5 to move downwards. The fixed plate 5 will drive the stamping column 8 and the saw tooth stamping plate 11 to move downwards continuously. The stamping column 8 will squeeze the saw blade through the circular opening 9 on the saw tooth support plate 3 and punch out a center hole in the center of the saw blade. At the same time, the teeth on the saw tooth stamping plate 11 will punch the surface of the saw blade and press out tooth grooves on the surface of the saw blade. The scrap material punched out from the surface of the saw blade will fall down through the feeding port 20 and the discharge port 21 and be discharged and collected. Then, control the first hydraulic telescopic rod 4 to drive the fixed plate 5 to move upwards and reset, and remove and replace the saw blade on the saw tooth support plate 3.
