Embodiment 1

[0036] refer to Figure 1-7, a cold heading machine for the production of automobile fasteners, including a frame 1, a hydraulic cylinder 2 is fixedly connected to the frame 1, and the output end of the hydraulic cylinder 2 is fixedly connected to a punch, the position of the punch and the feeding hole The position is set correspondingly, and a cut-off mechanism is set at the position of the feeding hole. The front end of the frame 1 is fixedly connected with a straightening mechanism 3, and a feeding mechanism 4 is arranged below the straightening mechanism 3. The hydraulic cylinder 2 is located in the frame 1. The cleaning box 6 is fixedly connected to the bottom of the cleaning box 6, and the cleaning box 6 and the unloading mechanism 4 are connected to each other. The straightening mechanism 3 includes an outer cylinder 301, and the inner side of the outer cylinder 301 is provided with a slideway 302, and the inside of the slideway 302 Three straightening blocks 303 are sl...

Embodiment 2

[0038] refer to Figure 1-7 , a cold heading machine for the production of automobile fasteners, comprising a frame 1, a hydraulic cylinder 2 is fixedly connected to the frame 1, and the output end of the hydraulic cylinder 2 is fixedly connected to a punch, and the front end of the frame 1 is fixedly connected to a Straightening mechanism 3, the outer end of the straightening mechanism 3 is provided with a cover plate 5, and the cover plate 5 is slidably embedded in the inner side of the frame 1, the front view of the cover plate 5 is an inverted U-shaped structure, and the end of the cover plate 5 is fixedly connected There is a rubber ring 501. The rubber ring 501 ensures a good seal between the frame 1 and prevents lubrication from entering the rear cavity. The rubber ring 501 and the frame 1 are elastically connected by a plurality of extrusion springs 8, hydraulic pressure The front end of the cylinder 2 is fixedly connected with a plurality of push rods 13 arranged para...

Abstract

The invention discloses a cold heading machine for the production of automobile fasteners, which comprises a hydraulic cylinder, a straightening mechanism, a blanking mechanism and a cleaning box. and three straightening blocks are slidingly embedded inside the slideway, and three first driving motors are arranged at one end of the outer cylinder, and the three first driving motors are respectively passed through the first threaded rod and the three straightening blocks The outer cylinder is located outside one end of the first driving motor and is provided with three sets of rollers. In the present invention, through the straightening mechanism, three sets of rollers in a circular array are set to realize the preliminary straightening operation of the material. The outer cylinder is set, and three straightening blocks are slidably embedded inside the outer cylinder. Through the mutual cooperation between the first drive motor, the first threaded rod and the limit block, the step-by-step transmission of the straightening blocks is realized. The straight blocks are combined into a tubular structure, which can better realize the straightening operation of the material.

Description

technical field [0001] The invention relates to a cold heading machine for producing automobile fasteners. Background technique [0002] Cold heading machine is a special equipment mainly used for mass production of fasteners such as nuts and bolts; the earliest cold heading machine in the world originated from Germany. The purpose of developing cold heading machine at that time was mainly for the large number of Manufacture bullet casings. [0003] The existing cold heading machine is equipped with a straightening mechanism inside, and the raw material can be processed after being straightened, but most of the existing ones are straightened by two rows of rollers, but when the straightening wheels wear out during long-term use Or when the position of the rotating shaft is shifted to a certain extent, the straightening effect at this time cannot achieve the desired effect, so it is necessary to improve the straightening mechanism; at the same time, the workpiece may stick t...
