Simple stretching device for hardware material

Abstract

The invention relates to the technical field of hardware, and discloses a simple stretching device for a hardware material. The simple stretching device comprises a workbench, and one side of the workbench is fixedly connected with a supporting plate. The upper surface of the supporting plate is fixedly connected with a heating device, and one side of the upper surface of the workbench is fixedlyconnected with a clamping device. The center of the upper surface of the workbench is fixedly connected with a stretching device body, and the other side of the upper surface of the workbench is fixedly connected with a flattening device. According to the simple stretching device for the hardware material, a motor, a first threaded rod, a pointer, scale marks and other structures are arranged, themotor is started to drive the first threaded rod to rotate, the first threaded rod drives the stretching device body to move, and therefore a hardware part can be subjected to reprocessing treatmentof stretching; by means of cooperative use of the pointer and the scale marks, the stretching length of the hardware part can be effectively controlled, and the stretching precision is improved; and compared with traditional arrangement, the structure is simplified, the operation difficulty is reduced, and popularization and use are convenient.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to a simple stretching device for hardware materials. Background technique [0002] After hardware production, some hardware materials will form defects due to various reasons such as processing. At this time, the hardware materials need to be reprocessed or returned to the furnace for recasting. The existing devices for reprocessing rod or narrow plate hardware materials are mainly With stretching device. [0003] The Chinese patent CN201821777452.0 discloses a simple stretching device for hardware materials, although it is mentioned in the patent that it is possible to stretch rod-type or narrow-plate hardware materials, and the hardware materials can be stretched after stretching. In the middle of the country, there are problems such as smoothing, but there are still some shortcomings: [0004] 1. In the prior art, when clamping and stretching rod or narrow hardware, the fixin...

AI Technical Summary

Problems solved by technology

[0004] 1. In the prior art, when clamping and stretching rod or narrow hardware, the fixing jig and stretching jig are prone to fall off from the hardware, especially when the clamping force of rod hardware is relatively strong. Weak, affecting the operation of the staff;

[0005] 2. In the prior art, the crank handle drives the traction rope to move, so as to carry out the stretching operation. Since the traction rope itself has a certain degree of ductility, and the traction rope tends to tilt and slide with the crank handle during work, which affects the effect after stretching , reducing the operating efficiency of the staff
