Description

Technical Field

[0001] The utility model relates to the technical field of screw forming dies, in particular to a screw forming die with a ring guide. Background Art

[0002] The combination of screws and washers can prevent loosening and pre-tighten. In the current existing technology, screws and washers are independent accessories and are combined together during installation, which affects the efficiency of installation and may cause the washers to be missed.

[0003] For this purpose, a guide screw with a ring is developed. The guide screw with a ring is a special-purpose screw. Different from traditional screws, it is composed of a screw and a washer.

[0004] This type of screw is difficult to process because a washer is set near the screw head in advance, and the screw processing process is subtractive processing. The setting of the washer will undoubtedly affect the material discharge during the screw processing process, resulting in the forming effect of the thread, and thus affecting the production quality of the product.

[0005] Therefore, the utility model proposes a forming die for a guide screw with a ring position, so as to solve the problems in the processing and forming process of the guide screw with a ring position and improve the product quality. Utility Model Content

[0006] In order to solve the problems existing in the prior art, the utility model provides a forming die with a guide screw with a ring position, which has a reasonable design and is easy to process and form.

[0007] The technical solution of the utility model is as follows:

[0008] A forming mold for a guide screw with a ring position includes a mold body. The upper surface of the mold body is provided with an introduction area, a forming area and a discharge area. The introduction area is provided with deep teeth, shallow teeth and grooves. The grooves, deep teeth and shallow teeth are arranged in sequence along the width direction of the mold body. The forming area and the discharge area are both provided with deep teeth and shallow teeth, and the deep teeth and shallow teeth are arranged in sequence along the width direction of the mold body.

[0009] Furthermore, the cross section of the deep teeth is triangular, the top of the deep teeth is transitioned by an arc, and the deep teeth are also transitioned by an arc.

[0010] Furthermore, the cross section of the shallow teeth is in the shape of an arc, and the shallow teeth are transitioned by arcs.

[0011] Furthermore, the depth of the shallow teeth is less than that of the deep teeth, and there are 2-3 shallow teeth.

[0012] Furthermore, the groove adopts a U-shaped groove structure, and the forming area and the discharge area are provided with deep teeth at positions corresponding to the groove.

[0013] Furthermore, the introduction zone is arranged to be inclined upward, the forming zone is arranged horizontally, and the discharge zone is arranged to be inclined downward.

[0014] Furthermore, the length of the introduction zone is greater than the sum of the lengths of the forming zone and the discharge zone.

[0015] Furthermore, a slope structure is provided on the outermost shallow tooth side of the mold body, and a right-angle structure is provided on the outermost deep tooth side of the mold body.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1) The utility model designs the structures of the introduction area, the forming area and the discharge area separately, which is different from the traditional tooth plate mold structure and is conducive to the forming of the guide screw with a ring position.

[0018] 2) The utility model provides a groove in the lead-in area, so that the thread close to the washer position is formed in the forming area, thereby avoiding the interference of the washer on the discharge.

[0019] 3) The length of the introduction zone of the present invention is set to be greater than the sum of the lengths of the forming zone and the discharge zone, which allows the threads far away from the washer position to be formed first, which is conducive to the processing and forming of the threads near the washer position.

[0020] 4) The shallow thread setting of the utility model is conducive to guiding the screw when it is screwed in, thereby increasing the screwing speed.

[0021] 5) One side of the mold body of the utility model is a right-angle structure, and the other side is a slope structure, which is conducive to limiting the washer during the processing and quickly discharging the screw tail. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] As shown in the figure, a forming mold for a guide screw with a ring includes a mold body 1. The upper surface of the mold body 1 is a tooth-shaped surface for thread forming. The upper surface of the mold body 1 includes an introduction area 101, a forming area 102 and a discharge area 103.

[0030] The introduction area 101 is set to be tilted upward, the forming area 102 is set horizontally, and the discharge area 103 is set to be tilted downward. This is the general setting method of the tooth plate and will not be repeated here.

[0031] The length of the introduction area 101 of the utility model is set to be greater than the sum of the lengths of the forming area 102 and the discharge area 103; this is conducive to the priority processing and forming of the threads far away from the gasket position, allowing the threads close to the gasket to be formed in the forming area 102, thereby solving the interference of gasket discharge.

[0032] The introduction area 101 is provided with grooves 2, deep teeth 3, and shallow teeth 4 in sequence. The forming area 102 and the discharge area 103 are different from the introduction area 101. The forming area 102 and the discharge area 103 are provided with deep teeth 3 and shallow teeth 4 in sequence; the forming area 102 and the discharge area 103 are not provided with grooves 2.

[0033] The cross section of the deep teeth 3 is triangular, and the top is transitioned by an arc, and arcs are also used between deep teeth 3; the deep teeth 3 on the mold body 1 are used to form deep grooves of the screw threads, and the gaps between deep teeth 3 are used to form deep and sharp threads.

[0034] The cross section of the shallow teeth 4 is in the shape of an arc, and the shallow teeth 4 are transitioned by an arc; the shallow teeth 4 on the mold body 1 are used to form shallow grooves of the screw threads, and the gaps between the shallow teeth 4 are used to form shallow and rounded threads; in this embodiment, only two shallow teeth 4 are required.

[0035] The groove 2 adopts a U-shaped groove structure, and the forming area 102 and the discharge area 103 are provided with deep teeth 3 at positions corresponding to the groove 2, so as to allow the threads close to the washer to be processed later.

[0036] An inclined surface structure 5 is provided on one side of the outermost shallow tooth 4 on the mold body 1 , and a right-angle structure 6 is provided on one side of the outermost deep tooth 3 on the mold body 1 ; in this embodiment, the inclined surface structure 5 is at 45° to the upper surface of the mold body 1 .

[0037] Working principle:

[0038] The screw nails enter the mold body from the introduction area. The introduction area is provided with grooves. The position near the washer is not processed first. The screw threads away from the washer are processed first and discharged to the side of the inclined structure. Since the introduction area is long, the threads away from the washer are basically processed and formed. When entering the forming area, the threads close to the washer begin to be processed. Since the threads away from the washer are basically processed and formed, the threads close to the washer can be smoothly discharged to the side of the inclined structure, thereby realizing processing and forming.
