Technical Field

[0001] This utility model relates to the technical field of saw blade processing equipment, specifically a punch loading device for the initial processing of saw blade blanks. Background Technology

[0002] Steel plates are a key material in the manufacture of various saw blades. They are typically made of high-strength alloy steel to ensure excellent wear resistance and toughness. Their thickness generally ranges from 1 mm to 5 mm, depending on the type of saw blade and application requirements. The choice of thickness directly affects the cutting performance and stability of the saw blade; thicker steel plates are usually used to withstand greater cutting loads, while thinner steel plates are suitable for precision cutting. Through precision machining and heat treatment, these steel plates can meet the diverse cutting requirements of materials such as wood and metal.

Detailed Implementation

[0024] 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.

[0025] Example:

[0026] Please see Figures 1 to 6 This utility model provides a technical solution:

[0027] A punching device for initial processing of saw blade blanks includes a mounting frame 1, an extrusion platform 2, a positioning assembly 3, a transmission assembly 4, a flattening assembly 5, a rolling wheel 6, and a power assembly 7. The mounting frame 1 is equipped with the extrusion platform 2, wherein:

[0028] Two positioning components 3 are horizontally movably mounted on the mounting frame 1. The positioning components 3 are used to position the steel sheet blank on the extrusion platform 2 to the center position of the extrusion platform 2. The flattening component 5 is vertically movably mounted on the mounting frame 1 and located directly above the extrusion platform 2. The flattening component 5 is used to press down the steel sheet blank that has been squeezed by the positioning components 3, so that it remains flat. The positioning components 3 and the flattening component 5 are connected by a transmission component 4, so that the horizontal movement of the positioning components 3 can drive the vertical movement of the flattening component 5.

[0029] In a preferred embodiment, the positioning component 3 includes a movable clamping block 31 and a damper 32. The movable clamping block 31 is horizontally movably mounted on the mounting frame 1 via the damper 32. The elastic force of the damper 32 allows the movable clamping block 31 to clamp both ends of the steel sheet blank, thereby achieving the positioning purpose. The movable clamping block 31 is trapezoidal, and the distance between the clamping surfaces of the two movable clamping blocks 31 is greater at the end closer to the rolling wheel 6 than at the end farther from the rolling wheel 6. This allows the steel sheet blank to enter from the end with the larger distance between the two movable clamping blocks 31, and as the distance between the two movable clamping blocks 31 gradually decreases, it gradually clamps the steel sheet blank and gradually corrects its position.

[0030] In a preferred embodiment, the transmission assembly 4 includes a slide 41 and a slider 42. The slide 41 is fitted onto the guide rail on the side of the mounting frame 1 and connected to the movable clamping block 31. When the movable clamping block 31 moves on the mounting frame 1, it will synchronously drive the slide 41 to move. The slider 42 is movably fitted onto the slide 41. When the slide 41 moves horizontally, the slider 42 moves relative to the slide 41. Then, the slider 42 moves vertically under the limiting action of the slide 41.

[0031] In a preferred embodiment, the flattening assembly 5 includes a connecting rod 51, a mounting box 52, a pressing plate 53, and a screw 54. The connecting rod 51 is vertically movably mounted on the mounting frame 1. One end of the connecting rod 51 is connected to the slider 42, and the other end is mounted on the mounting box 52. The vertical movement of the slider 42 drives the mounting box 52 to move vertically through the connecting rod 51. The pressing plate 53 is vertically movably mounted inside the mounting box 52. The screw 54 rotates on the mounting box 52 and passes through the pressing plate 53, wherein the screw 54 and the pressing plate 53 form a threaded engagement. The height of the pressing plate 53 from the mounting frame 1 can be adjusted by the screw 54, thereby achieving the purpose of flattening saw blade blanks of different thicknesses.

[0032] In a preferred embodiment, the upper surface of the slide table 41 has an inclined groove 411, and the slider 42 is movably fitted inside the inclined groove 411. The end of the inclined groove 411 away from the movable clamping block 31 is higher than the end near the movable clamping block 31. When the movable clamping block 31 moves towards the outer side of the mounting frame 1, the slide table 41 also moves towards the outer side of the mounting frame 1. Through the inclined groove 411, the slider 42 can be driven to move downward, and then through the connecting rod 51, the pressure plate 53 on the mounting box 52 is driven downward to flatten the saw blade blank. When the movable clamping block 31 moves towards the center of the mounting frame 1, the slide table 41 also moves towards the center of the mounting frame 1. Through the inclined groove 411, the slider 42 can be driven to move upward, and then through the connecting rod 51, the pressure plate 53 on the mounting box 52 is driven upward to release the flattening.

[0033] In a preferred embodiment, the roller 6 is rotatably mounted at the end of the mounting frame 1. The roller 6 is used to flatten the saw blade blank.

[0034] In a preferred embodiment, the power assembly 7 includes a belt drive assembly 71 and a motor 72, the motor 72 being poweredly connected to the roller 6 via the belt drive assembly 71.

[0035] The working principle of this utility model is as follows: Before feeding, the height of the pressure plate 53 from the mounting frame 1 is adjusted by screw 54 according to the thickness of the saw blade blank, so that it can flatten saw blade blanks of different thicknesses.

[0036] During feeding, the saw blade blank is first flattened by two rollers 6. The flattened saw blade blank enters from the end with the larger gap between the two movable clamping blocks 31. At this time, the flattened saw blade blank is actively conveyed by external equipment, while the gap between the two movable clamping blocks 31 continuously decreases. The saw blade blank pushes the two movable clamping blocks 31 to move towards the outer side of the mounting frame 1, and gradually corrects its position under the action of the elastic force of the damper 32. At the same time as correction and positioning, the movable clamping blocks 31 move towards the outer side of the mounting frame 1, and the slide table 41 also moves towards the outer side of the mounting frame 1. Through the inclined slide groove 411, the slider 42 can be driven to move downward, and then through the connecting rod 51, the pressure plate 53 on the mounting box 52 is driven downward to flatten the saw blade blank, so as to achieve the purpose of flattening the saw blade blank.

[0037] When it is time to stop feeding, the movable clamping block 31 moves toward the center of the mounting frame 1 under the action of the damper 32. The slide table 41 also moves toward the center of the mounting frame 1. Through the inclined slide groove 411, the slider 42 can be driven to move upward, and then through the connecting rod 51, the pressure plate 53 on the mounting box 52 is driven to move upward to release the flattening.

[0038] 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.
