Description

Technical Field

[0001] The utility model relates to the technical field of racket production, in particular to a forming preheating workbench used for racket production. Background Art

[0002] As we all know, a badminton racket is generally composed of a racket head, a racket shaft, a racket handle and the joint between the racket frame and the racket shaft. Most of the structure of a badminton racket is made of carbon fiber, which can greatly improve the batting performance of the badminton racket. In the manufacturing process of a badminton racket, a racket mold is needed to make the carbon fiber strips into a carbon fiber racket frame with a racket frame shape, and then a three-way joint is used to combine the carbon fiber racket frame and the carbon fiber racket shaft together to assemble a workpiece with the prototype of a racket.

[0003] Chinese Patent: CN202021173516.3 A racket frame stretching and forming machine, comprising a frame, a workbench fixed on the frame for processing the racket frame, a forming assembly installed on the workbench for stretching the racket frame and a pushing assembly for lifting the racket frame, the forming assembly comprising a fixed block fixedly installed on the workbench, a sliding block horizontally moving relative to the fixed block, and a driving cylinder driving the sliding block to move, the fixed block and the side walls of the sliding block form a forming surface that fits the inner wall of the racket frame after forming, the pushing assembly comprises a driving rod rotatably connected to the frame along a vertical plane, a connecting rod fixedly connected to the side wall of the driving rod, and a pushing rod rotatably connected to one end of the connecting rod away from the driving rod, the end of the driving rod away from the connecting rod and the pushing rod away from the end of the connecting rod both pass through the workbench, and the present application has the effect of facilitating unloading.

[0004] During the production process of the racket production equipment in the above patent and the prior art, it is necessary to manually connect the carbon fiber racket frame and the carbon fiber racket shaft to the three-way joint respectively and then use adhesive to fix them. However, since the curing of the adhesive takes a certain amount of time and the carbon fiber racket frame is prone to generate rebound force after bending, the end of the carbon fiber racket frame may be separated from the three-way joint and shrink outward under the action of the rebound force, so that the end of the carbon fiber racket frame cannot be embedded to a sufficient depth, which is likely to affect the stability of the racket structure after molding.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a molding preheating workbench for racket production, which has the following beneficial effects:

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The utility model is a molding preheating workbench for racket production, comprising a bottom plate 1, a vertical rod 7 and an annular frame 4, a positioning tube 12 is provided at the upper end of the annular frame 4, the bottom end of the vertical rod 7 is inserted into the interior of the positioning tube 12, a vertical plate 2 is fixedly arranged at the upper end of the bottom plate 1, a hot air blower 14 is provided at the rear end of the vertical plate 2, a positioning seat 3 is fixedly arranged at the front end of the vertical plate 2, the annular frame 4 is penetrated by the positioning seat 3, a protective shell 5 for limiting the annular frame 4 is provided on the positioning seat 3, a screw 6 inserted into the interior of the positioning seat 3 is provided in the middle part of the protective shell 5, the screw 6 is threadedly connected to the positioning seat 3, a U-shaped air outlet block 13 is provided above the positioning seat 3, and multiple air outlet blocks 13 are provided at both ends of the U-shaped air outlet block 13. An air outlet hole is formed, and the air outlet end of the hot air blower 14 is connected with the U-shaped air outlet block 13 through a duct 15. The annular frame 4 is placed on the positioning seat 3, and then the protective shell 5 is fixed on the positioning seat 3, so that the annular frame 4 is fixed on the positioning seat 3, and glue is added to the inside of the positioning tube 12. The vertical rod 7 is taken, and the bottom end of the vertical rod 7 is inserted into the positioning tube 12, so that the bottom end of the vertical rod 7 is bonded to the inside of the positioning tube 12. In this process, since this structure is placed vertically, the glue can be filled more evenly in the positioning tube 12. Further starting the hot air blower 14 can make hot air blow out at the air outlet, which can provide a hot air heating effect to the positioning tube 12, accelerate the solidification of the glue, and improve the docking efficiency and docking quality of the vertical rod 7 and the annular frame 4;

[0024] When the vertical rod 7 is connected to the positioning tube 12, the screw rod 6 is rotated, and then the protective shell 5 can be disassembled on the positioning seat 3, so that the annular frame 4 can be easily removed from the positioning seat 3, with a simple structure and convenient operation.

[0025] In this structure, two fixing plates 16 are symmetrically arranged at the rear end of the U-shaped air outlet block 13. The fixing plates 16 are fixed to the rear end of the vertical plate 2 by screws. The screw fixing method has the advantage of convenient assembly.

[0026] The lack of a limiting structure at the vertical rod 7 will make the vertical rod 7 not firmly placed on the front side of the vertical board 2. A lifter 8 is fixedly set on the top of the vertical board 2, and a limiting plate 9 is provided at the output end of the lifter 8. Two thrusters 10 are symmetrically arranged in the middle part of the vertical board 2, and a clamping block 11 for limiting the vertical board 2 is provided at the output end of the thruster 10. When the bottom end of the vertical rod 7 is inserted into the positioning tube 12, the lifter 8 is started, which can enable the lifter 8 to apply a pressure to the top end of the vertical rod 7, thereby limiting the top end of the vertical rod 7. Then, the thruster 10 is started, so that the two clamping blocks 11 clamp the vertical rod 7, thereby providing a limiting structure at the vertical rod 7, and making the vertical rod 7 more firmly placed on the front side of the vertical board 2.

[0027] Furthermore, the lifter 8 and the thruster 10 may both be telescopic cylinders.

[0028] Furthermore, handles are provided on both sides of the protective shell 5 to facilitate taking the protective shell 5 .

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
