Description

Technical Field

[0001] The utility model relates to a screw thread rolling support frame and belongs to the technical field of bolt processing. Background Art

[0002] The thread rolling machine is a multifunctional cold extrusion forming machine. The thread rolling machine can perform thread, straight grain, and oblique grain rolling on the screw in the cold state within its rolling force range; rolling of straight teeth, helical teeth, and helical spline gears; straightening, reducing diameter, rolling and various forming rolling. When rolling small-sized screws, the operator can manually convey the screw to the thread rolling machine or there is an automatic thread rolling machine. However, for the production of large-sized screws, the screws with diameters of 90, 85, 70, 65, 55, 52, 48, 42 mm are large in size and heavy in weight. The operator holds the screw and conveys it to the thread rolling machine. The physical labor is large, and the different conveying angles and forces lead to a high risk factor and easy production of waste.

[0003] The Chinese patent (CN216680025U) discloses a thread rolling machine support frame that can quickly replace wear parts. The upper end of the support frame body is provided with a threaded hole, a semicircular groove, and a slot. One end of the semicircular groove is closed, and the lower end of the support frame body is provided with a number of U-shaped slots. A tightening screw is installed at the threaded hole of the support frame body, and a tungsten steel rod is inserted into the semicircular groove of the support frame. The positioning column is installed at the slot of the support frame body. One end of the tungsten steel rod contacts the closed end of the semicircular groove of the support frame body, and the other end of the tungsten steel rod contacts the positioning end of the positioning column, and is tightened and fixed by the tightening screw. The lower end of the support frame body is provided with a number of U-shaped slots for fixed connection with the thread rolling machine equipment. This increases the service life of the thread rolling machine support frame, which is 12 times the life of the original support frame, and greatly reduces the time and cost of replacing the support frame.

[0004] The problem with the above patent is that a semicircular groove and a tightening threaded hole are provided on the upper part of the support frame body, and the alloy strip adopts a round tungsten steel rod to support the workpiece, which has a complex structure and a limited scope of use. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a screw rolling support frame with a simple structure. On the one hand, it is easy to produce and manufacture, has low cost, and is convenient to install; on the other hand, it can be used for a long time, is not easy to be damaged, and is easy to repair or replace parts.

[0006] The utility model discloses a screw thread rolling support frame, comprising a base, a lifting platform, a lifting device, a roller bracket and rollers symmetrically arranged on the lifting platform; the lifting platform is placed on the base through the lifting device, and the rollers are rotatably connected to the lifting platform through the roller bracket.

[0007] The screw is placed between two rollers, and the lifting device adjusts the height of the rollers on the lifting platform so that the center height of the screw is consistent with the center height of the thread rolling machine. The rollers replace manual operation and reduce the labor intensity of workers.

[0008] The roller is detachable and can be replaced according to the size of the screw rod, thereby improving the adaptability of the device.

[0009] The diameter of the roller is 30mm-90mm. The diameter of the roller is 30mm-90mm, which can adapt to the production of screws with sizes of 90, 85, 70, 65, 55, 52, 48, 42mm, etc.

[0010] The lifting device is a jack, which saves effort, has higher precision and is easy to adjust.

[0011] The base is made of solid metal, which increases the weight of the base and improves stability.

[0012] A moving mechanism is arranged at the bottom of the base, which facilitates the movement of the bracket. The moving mechanism is a universal wheel, and there are four universal wheels, which are evenly distributed below the base, and the universal wheels have a brake structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model realizes the support of the screw rod by arranging a base, a lifting platform, a lifting device, a roller bracket and rollers symmetrically arranged on the lifting platform. The structure is simple. On the one hand, it is easy to produce and manufacture, low cost, and easy to install; on the other hand, it can be used for a long time, is not easy to be damaged, and is easy to repair or replace parts.

[0015] (2) The roller is detachable. The roller can be detachable according to the size of the screw. Different rollers can be replaced according to the size of the screw, thereby improving the adaptability of the device.

[0016] (3) The diameter of the roller is 30mm-90mm. The diameter of the roller is 30mm-90mm, which can adapt to the production of screws of sizes such as 90, 85, 70, 65, 55, 52, 48, and 42mm. BRIEF DESCRIPTION OF THE DRAWINGS
