Description

Technical Field

[0001] The utility model belongs to the technical field of thread rolling dies, and relates to a thread rolling die with a detachable thread structure. Background Art

[0002] A thread rolling machine is a device specialized for producing screws. In actual processing, the thread rolling die continuously processes and extrudes the screw rod. The wear degree of the thread rolling teeth at the front end of the thread rolling die is extremely high, while the wear degree of the rest is very low. The existing thread rolling dies are all integrally formed. After the thread rolling teeth are worn to a certain extent, the entire thread rolling die needs to be replaced. Now, replacing the integrally formed thread rolling die has a high economic cost and wastes materials in production.

[0003] For example, a Chinese patent discloses a detachable thread rolling die [Application No.: 201920873986.1], which includes a base, a thread rolling die body, and a thread rolling tooth piece slidably connected in the thread rolling die body. The thread rolling die body includes a bottom plate and an "L"-shaped support plate. An installation groove is formed on the surface of the base, and clamping parts are symmetrically arranged on the inner side wall of the installation groove. The thread rolling die body is fixed in the installation groove through the clamping parts. Summary of the Utility Model

Detailed Description of the Embodiment

[0024] As Figures 1 - 3 shown, a thread rolling plate with a detachable threading structure includes a thread rolling plate 1. A hollow chamber 2 is provided inside the thread rolling plate 1. A plurality of thread mounting grooves 3 are horizontally arranged on one side of the hollow chamber 2. The thread mounting grooves 3 penetrate left and right. A plurality of threading plates 5 corresponding to the thread mounting grooves 3 one by one and having thread parts 4 at their ends are provided inside the hollow chamber 2. The thread parts 4 of the threading plates 5 horizontally pass through the thread mounting grooves 3 and protrude outside the thread rolling plate 1. Openings are provided on the front sides of both the hollow chamber 2 and the thread mounting grooves 3. A thread mounting plate 6 is also slidably arranged inside the hollow chamber 2. A threading limit structure 7 is provided on the thread mounting plate 6. A thread depth adjustment mechanism 8 connected to the thread mounting plate 6 is also provided on the side of the thread rolling plate 1 away from the thread mounting grooves 3. A side baffle structure 9 is also provided on the front side of the thread rolling plate 1.

[0025] In the present utility model, the thread plate with a thread part is separately arranged from the thread rolling plate. The thread part can extend out of the thread rolling plate through the thread mounting groove 3. The thread plate 5 is limited and fixed by the thread limiting structure 7 on the thread mounting plate 6. The thread mounting plate and the thread plate can be inserted or taken out through the hollow chamber 2 and the front opening of the thread mounting groove 3. After the thread plate is installed, the opening is blocked by the side baffle structure so that the thread plate and the thread rolling plate are combined into one body. The thread depth adjusting mechanism 8 can drive the thread mounting plate 6 and the thread plate to move left and right, thereby adjusting the length of the thread part extending out of the thread rolling plate.

[0026] Specifically, the thread mounting plate 6 includes a left mounting plate 11 and a right mounting plate 12 fixed by two connecting plates 10. The thread limiting structure 7 is arranged on the right mounting plate 12, and the inner end of the thread plate 5 abuts against the left mounting plate 11. The left mounting plate 11 and the thread limiting structure 7 arranged on the right mounting plate 12 can limit the thread plate left and right.

[0027] Specifically, the thread limiting structure 7 includes a number of thread plate connecting grooves 13 arranged on the right mounting plate 12 and corresponding to the thread mounting grooves 3 one by one. A left and right limiting structure is arranged between the thread plate connecting grooves 13 and the thread plate 5. The left and right limiting structure includes left and right limiting blocks 14 protruding from the upper and lower sides of the thread plate connecting grooves 13. The upper and lower sides of the thread plate 5 are recessed inwardly to form left and right limiting grooves 15. The left and right limiting blocks 14 are inserted into the left and right limiting grooves 15. When the thread plate is inserted into the thread plate connecting groove 13, the left and right limiting blocks on the upper and lower sides of the thread plate connecting groove can be inserted into the left and right limiting grooves on the upper and lower sides of the thread plate, so as to limit the thread plate left and right and prevent the thread plate from sliding left and right.

[0028] Specifically, the thread depth adjusting mechanism 8 includes a translation driver 16 fixed on the thread rolling plate 1. The output shaft of the translation driver 16 is connected to the left mounting plate 11 through a push-pull connection structure. The translation driver connected to the left mounting plate 11 through the push-pull connection structure can drive the thread mounting plate 6 to slide left and right, so as to adjust the thread depth during bolt processing.

[0029] Those skilled in the art should understand that the translation driver can be an oil cylinder, a cylinder or a linear motor, etc.

[0030] Specifically, the push-pull connection structure includes a push-pull sliding groove 17 horizontally arranged on the left mounting plate 11. The end of the output shaft of the translation driver 16 is fixedly connected with a push-pull sliding block 18. The cross-sections of the push-pull sliding groove 17 and the push-pull sliding block 18 are both T-shaped. The cooperation of the push-pull sliding groove 17 and the push-pull sliding block 18 can realize the connection and disassembly of the translation driver 16 and the left mounting plate, and the cross-sections of the push-pull sliding groove 17 and the push-pull sliding block 18 being both T-shaped can realize the push-pull linkage between the translation driver 16 and the left mounting plate.

[0031] Specifically, openings are provided on both sides of the push-pull sliding groove 17 and the thread plate connection groove 13 close to the side baffle structure 9, which facilitates the connection and disassembly of the push-pull slider 18, and also facilitates the connection and disassembly of the thread plate and the right mounting plate.

[0032] Specifically, the side baffle structure 9 includes a side baffle 19, and the side baffle 19 is detachably fixed on the thread rolling plate 1. The side baffle 19 is fixed on the thread rolling plate 1 by a plurality of bolts. After the thread mounting plate 6 and the thread plate are installed into the thread rolling plate, the openings of the hollow chamber and the thread mounting groove can be blocked by the side baffle so that the thread plate and the thread rolling plate can be combined into one body. After the side baffle is removed, the thread plate can be removed from the thread rolling plate.

[0033] Specifically, there is a gap between the left mounting plate 11 and the right mounting plate 12.

[0034] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0035] Although terms such as thread rolling plate 1, hollow chamber 2, thread mounting groove 3, thread portion 4, thread plate 5, thread mounting plate 6, thread limiting structure 7, thread depth adjusting mechanism 8, side baffle structure 9, connecting plate 10, left mounting plate 11, right mounting plate 12, thread plate connection groove 13, left and right limiting blocks 14, left and right limiting grooves 15, translation driver 16, push-pull sliding groove 17, push-pull slider 18, side baffle 19, etc. are used more in this article, using these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
