Description

Technical Field

[0001] The utility model relates to the technical field of racket processing, and particularly relates to a punching mechanism. Background Art

[0002] In the processes of pipe production, use, etc., pipe punching is a very crucial process, directly affecting the quality and production efficiency of pipe punching. In the process of racket production, a punching machine is required to punch the raw materials of the racket. Among them, the positioning mechanism of the metal punching machine is used to position the raw materials of the racket rod to ensure the processing accuracy.

[0003] The patent document with the publication number CN216540409U discloses a positioning mechanism of a metal punching machine. When in use, a metal rod is inserted into the first through hole and punched by the punching machine. The waste chips generated during punching fall into the waste box through the second through hole, which can prevent the waste chips from being scattered onto the machine table. In the later stage, only the waste box needs to be cleaned, making it more convenient to clean the waste chips and avoiding accidental injuries to the staff caused by flying waste chips. The semi-circular groove formed on the positioning frame cooperates with the first through hole, and at the same time, the pressing plate is pressed down by the second screw. The positioning frame is stabilized by the pressure, so that the raw materials of the racket rod placed in the first through hole can be stably fixed, ensuring the processing quality of the racket rod.

[0004] Although the above-mentioned positioning mechanism of the metal punching machine can solve the corresponding technical problems, when inserting the metal rod into the first through hole, it is difficult to quickly and accurately align the to-be-punched part of the metal rod with the first groove, which not only reduces the punching efficiency but also easily causes misalignment between the to-be-punched part and the first groove during the punching process, thus reducing the punching effect of the racket rod. Therefore, we propose a punching mechanism. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, an embodiment of the present utility model provides a punching mechanism, including: a machine base 1, a positioning mechanism 3 for positioning the racket rod, a supporting mechanism 2 for supporting the positioning mechanism 3, a punching mechanism 4 for punching the racket rod, and a limiting mechanism 5 for limiting one end of the racket rod. The punching mechanism 4, the positioning mechanism 3, and the supporting mechanism 2 are sequentially arranged in the inner cavity of the machine base 1 from top to bottom, and the limiting mechanism 5 is arranged on the punching mechanism 4; the limiting mechanism 5 includes a blocking member 51 capable of contacting one end of the racket rod, and the punching mechanism 4 is provided with an adjusting member 52 for driving the blocking member 51 to move horizontally. The bottom horizontal line of the blocking member 51 is lower than the bottom horizontal line of the punching mechanism 4.

[0026] Among them, the blocking member 51 includes an inner plate 511 movably arranged on the adjusting member 52. An outer sleeve 512 is slidably sleeved on the surface of the inner plate 511. A limiting block 513 fixedly connected to the bottom of the inner plate 511 and contacting the inner wall surface of the outer sleeve 512 is provided. When the limiting mechanism 5 moves downward with the punching mechanism 4, the bottom of the outer sleeve 512 can first contact the top of the supporting mechanism 2, and the outer sleeve 512 then slides on the surface of the inner plate 511 to realize the contraction operation of the blocking member 51, which can not only ensure that the blocking member 51 continuously limits one end of the racket rod during the punching process, but also avoid the phenomenon that the blocking member 51 is broken due to directly contacting the supporting mechanism 2 with an unchanged length.

[0027] Among them, a movable plate 5111 integrally formed with the front side of the support plate 42 is provided on the front side of the top of the inner plate 511. A scale line for cooperating with the movable plate 5111 is provided on the surface of the support plate 42. The starting position of the scale line is aligned with the central axis of the punching knife 43. The left side of the movable plate 5111 and the left side of the outer sleeve 512 are on the same plane. When the adjusting member 52 adjusts the position of the blocking member 51, the movable plate 5111 synchronously slides on the front side of the support plate 42, and thus the specific moving distance of the blocking member 51 can be intuitively understood by means of the scale line, achieving the effect of precise adjustment.

[0028] Among them, a spring 514 is provided at the bottom of the inner cavity of the outer sleeve 512. The top and bottom ends of the spring 514 are respectively fixedly connected to the limiting block 513 and the outer sleeve 512. Through the elastic force of the spring 514, it can not only buffer the inner plate 511 when the blocking member 51 contracts, but also automatically reset the outer sleeve 512 for the next use.

[0029] Among them, the distance adjusting member 52 includes a support block 521 provided on the punching mechanism 4. A screw rod 522 horizontally penetrates through the support block 521 movably. The surface of the screw rod 522 is rotationally connected to the penetrating portion of the support block 521 through a bearing. One end of the screw rod 522 is fixedly connected with a knob 523. The inner plate 511 is threadedly sleeved on the surface of the screw rod 522. By rotating the knob 523, the blocking member 51 can be driven to move horizontally along the axial direction of the screw rod 522, and thus the horizontal position of the blocking member 51 can be adjusted to correspond to different punching requirements and adjust the position of the blocking member 51 accordingly.

[0030] Among them, the punching mechanism 4 includes an electric telescopic rod 41 installed at the top of the inner cavity of the machine base 1. The output end of the electric telescopic rod 41 is horizontally and fixedly connected with a support plate 42. A punching knife 43 is installed at the bottom of the support plate 42. The top of the support block 521 is fixedly connected with one side of the bottom of the support plate 42. The top of the inner plate 511 is slidably connected with the bottom of the support plate 42. By starting the electric telescopic rod 41, the support plate 42, the punching knife 43 and the limiting mechanism 5 can be driven to move downward synchronously, and the punching knife 43 can be used to punch the racket rod on the positioning mechanism 3, and the limiting mechanism 5 can be used to limit one end of the racket rod.

[0031] Among them, two convex blocks 44 are vertically and fixedly connected to the bottom of the support plate 42. One end of the screw rod 522 away from the knob 523 is rotationally connected to one side of one of the convex blocks 44 through a bearing, which can play an auxiliary supporting role for the screw rod 522 and help improve the stability of the screw rod 522 during rotation. A rubber pad 45 is glued to the bottom of the convex block 44. When the electric telescopic rod 41 drives the support plate 42 and the punching knife 43 to move downward, the rubber pad 45 can contact the top of the positioning mechanism 3, and can reduce the impact force when the convex block 44 contacts the positioning mechanism 3, playing a buffering role.

[0032] Among them, the positioning mechanism 3 includes two symmetrically arranged positioning frames 31. A cavity through which the punching knife 43 passes is formed between the two positioning frames 31. A through hole 32 for inserting the racket rod is horizontally opened on the positioning frame 31. The through hole 32 is communicated with the cavity. By placing the racket rod in the inner cavity of the through hole 32, the racket rod can be positioned for subsequent punching operations. The distance between the opposite sides of the two convex blocks 44 is equal to the distance between the opposite sides of the two positioning frames 31.

[0033] Among them, the supporting mechanism 2 includes a support 21 fixedly connected to the bottom of the inner cavity of the machine base 1. The positioning frame 31 is installed on the top of the support 21. A through groove communicated with the cavity is opened on the top of the support 21. A collection box 22 for collecting punching debris is placed in the inner cavity of the support 21.

[0034] The working principle of the present utility model is as follows: Rotate the knob 523, and the knob 523 drives the screw rod 522 to rotate. Under the action of the thread, the screw rod 522 drives the inner plate 511, the outer sleeve 512, the limit block 513, the spring 514 and the movable plate 5111 to move horizontally along the axial direction of the screw rod 522 synchronously, so that the blocking member 51 can be adjusted to the required position according to the punching requirement of the racket rod; then insert one end of the racket rod into the inner cavity of the through hole 32 and penetrate to the outside of the positioning frame 31, so that one end of the racket rod abuts against one side of the outer sleeve 512, and the blocking member 51 can be used to limit one end of the racket rod to prevent the racket rod from moving excessively, so that the punching part of the racket rod can be quickly aligned with the punching knife 43; then start the electric telescopic rod 41, and the output end of the electric telescopic rod 41 drives the support plate 42, the punching knife 43, the convex block 44, the rubber pad 45, the blocking member 51 and the distance adjusting member 52 to move downward synchronously. The bottom of the outer sleeve 512 first contacts the top of the collection box 22, and the output end of the electric telescopic rod 41 continues to drive the support plate 42 to move downward, so that the outer sleeve 512 slides on the surface of the inner plate 511, the spring 514 is stressed and contracts, and the punching knife 43 gradually enters the cavity until the rubber pad 45 contacts the top of the positioning frame 31, and the punching of the racket rod can be completed by using the punching knife 43; finally, after the punching is completed, start the electric telescopic rod 41 again, so that the output end of the electric telescopic rod 41 drives the support plate 42 and the limiting mechanism 5 to move upward until the horizontal line at the bottom of the outer sleeve 512 is higher than the horizontal line at the top of the through hole 32 (as Figure 3 shown), and the punched racket rod can be taken out. After taking out, the output end of the electric telescopic rod 41 drives the support plate 42 and the limiting mechanism 5 to move downward until the horizontal line at the bottom of the outer sleeve 512 is lower than the horizontal line at the bottom of the through hole 32 (as Figure 2 shown), which is convenient for the next punching operation of the racket rod.

Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
