Description

Technical Field

[0001] The present application relates to the technical field of zipper processing, and in particular to a tooth punching device for hardware processing. Background Art

[0002] Hardware refers to metal products used in furniture, mechanical equipment and other fields, among which zippers are a type of hardware. In the zipper production process, teeth, such as plastic steel teeth, need to be planted on the zipper tape (or chain tape, zipper cloth tape, divided into left chain tape and right chain tape), and due to process reasons, the teeth are arranged continuously. The entire zipper tape needs to be divided into several zipper units, and a punching machine needs to be used to punch and remove the teeth of the entire zipper tape between the zipper units, and the teeth on the zipper tape between the zipper units are broken and removed to separate the zipper units from each other.

[0003] Chinese patent authorization announcement number: CN213613801U discloses a zipper processing punching device, including a base. This solution is provided with a pull ring. Before punching, the pull ring is lifted up, and the cloth strip of the punched zipper is passed through two U-shaped frames on the base, and then the hand is released. Under the action of the spring, the zipper cloth strip can be pressed and positioned. In this way, when the punching operation is performed, the punching position can be accurately positioned, which greatly improves the product quality.

[0004] The above scheme uses two pressing rollers to press and position the zipper strip. Only two pressing points may not be sufficient to ensure that the entire zipper tape remains straight throughout its entire length. Between the pressing points, the zipper tape may bend or relax due to the elasticity of the material itself or other external factors (such as uneven tension), so that the zipper tape is not completely straight. Therefore, during the punching process, the punching force and effect may vary due to the relaxation or bending of the zipper tape. The teeth on some zipper units may not be completely removed by punching, while the teeth on other zipper units may be over-punched, which will result in inconsistent punching quality and affect the performance and appearance of the zipper.

[0005] Therefore, it is necessary to provide a punching device for hardware processing to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0007] Based on the above-mentioned problems existing in the prior art, the problem to be solved by the present application is: to provide a tooth punching equipment for hardware processing, during which the tooth punching upper die synchronously drives the U-shaped rods on both sides to move, thereby driving the support rods and the connecting blocks to move.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0029] like Figure 1-5 As shown, a punching device for hardware processing includes: a base 1 and a positioning assembly 4, a punching lower die 2 is installed on the top of the base 1, an L-shaped plate 3 is fixedly connected to the top of the base 1, a cylinder 5 is installed on the top of the L-shaped plate 3, a mounting seat 6 is installed on the output end of the cylinder 5, a punching upper die 7 matching the punching lower die 2 is installed on the bottom of the mounting seat 6, both sides of the mounting seat 6 are fixedly connected to U-shaped rods 9 through brackets, a plurality of support columns 11 are fixedly connected to the top of the base 1, and the positioning assembly 4 is located at the top of the base 1, and the positioning assembly 4 includes a support rod 41 and a pair of support arms 4 4. Both ends of the support rod 41 are fixedly connected with a sliding sleeve 42, and the sliding sleeve 42 is slidably sleeved on the outer enclosure of the support column 11. The outer enclosure of the support rod 41 is fixedly connected with a connecting block 43, and the inner side of the connecting block 43 is rotatably connected with a rotating shaft 46. The two ends of the rotating shaft 46 are respectively fixedly connected to a pair of support arms 44, and a positioning wheel 45 is rotatably connected between the pair of support arms 44. The outer end of the rotating shaft 46 is sleeved with a torsion spring 47, and the two ends of the torsion spring 47 are respectively fixedly connected to the support arms 44 and the connecting block 43. There are two positioning components 4, and the two positioning components 4 are symmetrically distributed on both sides of the punching die 2.

[0030] The present invention is used for processing hardware, specifically, for punching and removing teeth of the entire zipper tape, and the teeth on the zipper tape between the zipper units are punched and removed to separate the zipper units from each other. The zipper tape is pulled by a traction mechanism into between the punching upper die 7 and the punching lower die 2. The punching operation can be completed by starting the cylinder 5 to control the punching upper die 7 to move downward, and then the punching upper die 7 is controlled by the cylinder 5 to reset, and then the traction mechanism is used to control the zipper tape to move a certain distance, and the above operation is repeated to complete the continuous punching operation.

[0031] The traction mechanism includes a traction motor and a traction wheel. The traction motor is used to drive the traction wheel to move the zipper tape. This technology is prior art and can be known to those skilled in the art, so it will not be described in detail.

[0032] In addition, the positioning components 4 are respectively located on both sides of the punching lower die 2. The torsion spring 47 is set to use its own elastic force to apply a torsional effect to the rotating shaft 46. Under the transmission action of the support arm 44, the positioning wheel 45 can be abutted against the zipper tape on the top of the base 1, and the zipper tape can be pressed and positioned on both sides of the stamping point of the zipper tape to avoid its displacement during the processing. In the process of punching teeth, the upper die 7 of the punching teeth synchronously drives the U-shaped rods 9 on both sides to move. When the U-shaped rods 9 contact the two support rods 41, they synchronously drive the support rods 41 and the connecting block 43 to move again. At this time, the positioning wheel 45 can roll along the top of the base 1 under the action, and the two positioning wheels 45 move away from each other, ensuring that the zipper tape between the two positioning components 4 remains in a straight state, so as to obtain consistency in the punching force and effect, thereby improving the quality of the punching teeth. When the punching teeth are completed, the upper die 7 of the punching teeth moves upward, and the positioning wheel 45 is reset under the action of the torsion spring 47.

[0033] It should be noted that when the positioning wheel 45 in the positioning assembly 4 is reset, a force is exerted on the zipper tape, which may cause the zipper tape to wrinkle. However, the zipper tape can be moved by the provided traction mechanism and can be straightened again.

[0034] like Figure 4 As shown, one end of the support column 11 away from the base 1 is fixedly connected to a limiting block for limiting the sliding sleeve 42 to prevent the sliding sleeve 42 from falling off, and a buffer pad is installed on the side of the limiting block close to the sliding sleeve 42 to reduce the impact force generated between the sliding sleeve 42 and the limiting block during the resetting process. The outer sleeve of the support column 11 is provided with a spring 2 12, and the two ends of the spring 2 12 are respectively fixedly connected to the base 1 and the limiting block. When the support rod 41 is pressed down, the sliding sleeve 42 will compress the spring 2 12. When the punching is completed, the spring 2 12 can also provide a resetting force for the torsion spring 47.

[0035] like Figure 4 As shown, a relief groove is provided at the top of the base 1, and an annular groove is provided on the outer periphery of the positioning wheel 45. The relief groove and the annular groove are used to accommodate the teeth on the zipper tape.

[0036] like Figure 1 As shown, a pair of slide bars 10 are fixedly connected to the top of the mounting seat 6 , and the pair of slide bars 10 both penetrate the L-shaped plate 3 and are slidably connected to the L-shaped plate 3 .

[0037] In this embodiment, it is used to guide the mounting seat 6. During the movement of the mounting seat 6, the slide rod 10 can slide in the L-shaped plate 3 to improve the stability of the punching teeth.

[0038] like Figure 1-2As shown, a protective component 8 is provided at the bottom of the mounting seat 6, and the protective component 8 includes a transparent cover 81. A through hole is opened at the top of the transparent cover 81, and the punching upper mold 7 passes through the through hole. A telescopic rod 82 is fixedly connected between the transparent cover 81 and the mounting seat 6, and a spring 83 is provided on the outer sleeve of the telescopic rod 82. The two ends of the spring 83 are fixedly connected to the transparent cover 81 and the mounting seat 6 respectively.

[0039] In this embodiment, when the tooth punching process is in progress, the mounting seat 6 drives the tooth punching upper die 7 to move in the vertical direction, the transparent cover 81 first contacts the tooth punching lower die 2, and the tooth punching upper die 7 continues to move. During this process, the telescopic rod 82 and the spring 83 will shrink until the tooth punching operation is completed. The transparent cover 81 can achieve the purpose of protection to prevent the teeth from causing damage to the staff during the tooth punching process.

[0040] Working principle: by starting the cylinder 5 to control the upper die 7 to move downward, the tooth punching operation is completed, and then the cylinder 5 is used to control the upper die 7 to reset, and then the traction mechanism is used to control the zipper belt to move a certain distance, and the above operation is repeated to complete the continuous tooth punching operation. The torsion spring 47 uses its own elastic force to apply a torsion effect to the rotating shaft 46, and the positioning wheel 45 can be abutted against the zipper belt on the top of the base 1 under the transmission effect of the support arm 44, and the zipper belt can be pressed and positioned on both sides of the stamping point to avoid its deviation during the processing process. During the tooth punching operation, the tooth punching upper die 7 synchronously drives the U-shaped rods 9 on both sides to move. When the U-shaped rods 9 contact the two support rods 41, they synchronously drive the support rods 41 and the connecting block 43 to move again. At this time, the positioning wheel 45 can roll along the top of the base 1 under the action, and the two positioning wheels 45 move away from each other to ensure that the zipper tape between the two positioning components 4 remains in a straight state to obtain consistency in the tooth punching force and effect, thereby improving the tooth punching quality. When the tooth punching is completed, the tooth punching upper die 7 moves upward, and the positioning wheel 45 is reset under the action of the torsion spring 47.

[0041] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
