Description

Technical Field

[0001] The utility model relates to a roller support backing plate for a thread rolling machine, belonging to the technical field of support components. Background Art

[0002] Bolts are commonly used parts in daily life or various machines. In the production process of some bolts, a thread rolling machine is required to complete the operation, such as tie bolts and anchor bolts. At present, the rollers of the thread rolling machine are divided into fixed rollers and movable rollers. The fixed rollers are fixed on the support backing plate through bearing seats, and the movable rollers are fixed on the moving mechanism through bearing seats. During thread rolling, the screw rod is placed between the movable roller and the fixed roller, and then the movable roller moves closer to the fixed roller to reach the thread rolling position for thread rolling. However, at present, the screw rod is manually placed between the movable roller and the fixed roller, and there is no positioning and supporting device, resulting in inaccurate placement position of the screw rod and easy skew, which affects the subsequent thread rolling effect. In addition, the screw rod needs to be held by someone all the time from placement to thread rolling, increasing the labor intensity. Content of the Utility Model

[0003] The utility model provides a roller support backing plate for a thread rolling machine, which solves the problems that there is no positioning and supporting device on the current support backing plate, resulting in inaccurate placement position of the screw rod and easy skew, affecting the subsequent thread rolling effect. In addition, the screw rod needs to be held by someone all the time from placement to thread rolling, increasing the labor intensity.

[0004] The utility model relates to a roller support backing plate for a thread rolling machine, including a backing plate body. There are two pairs of support plates on the backing plate body. A fixed roller is rotatably installed on the top of one pair of support plates through a bearing seat, and a movable roller is rotatably installed on the top of the other pair of support plates through a bearing seat. A slide plate is fixed on the support plate at the bottom of the movable roller, and the slide plate is connected to a translation mechanism. Guide sleeves are fixed on the front and rear support plates of the fixed roller, and horizontal guide rods are arranged in the guide sleeves. Vertical telescopic rods I are fixed at the right ends of the front and rear guide rods. A semi-circular support sleeve is fixed at the top of the front telescopic rod I, and a thimble shaft coaxial with the support sleeve is fixed at the top of the rear telescopic rod I.

[0005] As a preference, a limiting vertical plate is fixedly arranged at the top opening of the support sleeve to better prevent the rod to be thread rolled from slipping out.

[0006] As a preference, the bottoms of the front and rear telescopic rods I are fixedly connected with a reinforcing rod, and the structure is more stable.

An activity sleeve through which the first telescopic rod extending from the front side can pass is arranged in the inner hole of the reinforcing rod. The outer end of the activity sleeve is fixed with a second telescopic rod. The top of the second telescopic rod is fixed with an end limiting sleeve. The outer end face of the end limiting sleeve is closed. A locking bolt for locking the activity sleeve is arranged on the reinforcing rod. The end of the other end of the rod to be rolled can be limited through the end limiting sleeve to prevent the axial movement of the rod to be rolled during thread rolling. Moreover, the position of the end limiting sleeve can be adjusted according to the length of the rod to be rolled.

[0009] As a preference, the top of the second telescopic rod is fixed with an arc-shaped fixing plate. The end limiting sleeve is fixed on the fixing plate through bolts. Appropriate end limiting sleeves can be replaced according to the diameter of the rod to be rolled.

[0017] The following further describes the utility model with reference to the embodiments.

[0018] Example 1 is as follows Figures 1 to 3 As shown, the utility model is a roller support backing plate for a thread rolling machine, including a backing plate body 1. There are two pairs of support plates 2 on the backing plate body 1. A fixed roller 4 is rotatably installed on the top of a pair of support plates 2 through a bearing seat. A movable roller 10 is rotatably installed on the top of the other pair of support plates 2 through a bearing seat. A slide plate 12 is fixed on the support plate 2 at the bottom of the movable roller 10. The slide plate 12 is connected to a translation mechanism. Guide sleeves 3 are fixed on the front and rear support plates 2 of the fixed roller 4. A horizontal guide rod 9 is arranged in the guide sleeve 3. Vertical telescopic rods I 8 are fixed at the right ends of the front and rear guide rods 9. A semi-circular support sleeve 5 is fixed at the top of the front telescopic rod I 8. A thimble shaft 7 coaxial with the support sleeve 5 is fixed at the top of the rear telescopic rod I 8.

[0019] Before work, first adjust the height of the telescopic rod I 8 according to the diameter size of the rod to be rolled 16. During work, the translation mechanism drives the movable roller 10 away from the fixed roller 4. Then place the thread rolling end of the rod to be rolled 16 towards the thimble shaft 7 on the support sleeve 5. The thimble shaft 7 is inserted into the process hole of the rod to be rolled 16. Then move the guide rod 9 to make the rod to be rolled 16 as close as possible to the fixed roller 4. Then the translation mechanism drives the movable roller 10 to approach the fixed roller 4. When the movable roller 10 is in contact with the rod to be rolled 16, it will push the rod to be rolled 16 to move. When the movable roller 10 moves to the thread rolling position, the movable roller 10 and the fixed roller 4 cooperate to complete the thread rolling work.

[0020] Example 2: On the basis of Example 1, a limiting vertical plate 6 is fixedly arranged at the top opening of the support sleeve 5.

[0021] The bottom ends of the front and rear telescopic rods I 8 are fixedly connected with a reinforcing rod 21.

[0022] An arc-shaped mounting plate 15 is fixed at the top of the front telescopic rod I 8. The support sleeve 5 is detachably fixed on the mounting plate 15 through bolts. The rear ends of the movable roller 10 and the fixed roller 4 are both connected with thread rolling motors.

[0023] The reinforcing rod 21 is a hollow square sleeve structure. An activity sleeve 20 that can pass through the telescopic rod one 8 on the front side is arranged in the inner hole of the reinforcing rod 21. A telescopic rod two 19 is fixed to the outer end of the activity sleeve 20. An end limiting sleeve 17 is fixed to the top of the telescopic rod two 19. The outer end face of the end limiting sleeve 17 is closed. A locking bolt for locking the activity sleeve 20 is arranged on the reinforcing rod 21. Before placing the rod to be rolled 16, first loosen the locking bolt, then move the activity sleeve 20 outwards so that the end limiting sleeve 17 is far away from the reinforcing rod 21. Then, after placing the rod to be rolled 16 on the support sleeve 5, move the activity sleeve 20 inwards so that the end limiting sleeve 17 is limited at the outer end of the rod to be rolled 16. Then tighten the locking bolt. The end limiting sleeve 17 only needs to be attached to the outer end of the rod to be rolled 16 without applying axial pressure.

[0024] A circular arc-shaped fixing plate 18 is fixed to the top of the telescopic rod two 19. The end limiting sleeve 17 is fixed to the fixing plate 18 by bolts. Both the telescopic rod two 19 and the telescopic rod one 8 include a telescopic sleeve and a movable rod. The movable rod is sleeved in the telescopic sleeve and can extend out of the top of the telescopic sleeve. An adjusting bolt is arranged on the upper part of the telescopic sleeve.

[0025] The translation mechanism includes a horizontal slide rail fixed to the top of the base plate body 1. A slider is arranged on the slide rail. The top of the slider is fixed to the slide plate 12. A nut 11 is fixed to the bottom of the slide plate 12. The nut 11 is connected with a lead screw 13. The lead screw 13 is rotatably installed on the base plate body 1. The outer end of the lead screw 13 is fixed with a translation motor 14. The translation motor 14 is fixed to the base plate body 1.
