AI Technical Summary
The existing cold heading machine's feeding and blocking device cannot adjust the guiding angle, causing the material to fall into the collection box at too high a speed, resulting in a large impact force and easily damaging the material.
A safety material blocking device was designed, comprising a base plate, a primary guide box, a rotating shaft, a nut, a buffer mechanism, and a secondary guide box. By adjusting the angle of the rotating shaft and the buffer mechanism, the impact force is absorbed, and the material speed is reduced.
It enables flexible adjustment of the material guiding angle and provides a buffering effect, reducing the impact force when the material enters the collection box and protecting the material from damage.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold heading machine technology, and in particular to a safety stop device for cold heading machines. Background Technology
[0002] Cold heading machines are specialized equipment primarily used for the mass production of fasteners such as nuts and bolts. During material feeding, cold heading machines require a material guide device to position and guide the material for centralized collection. However, existing cold heading machine material guide devices are fixed installations, unable to adjust the guide angle, making it difficult to meet different usage requirements. Furthermore, the material deceleration effect is insignificant, resulting in the material falling into the collection box at a relatively high speed. This rapid fall generates significant impact force, easily damaging the material. Therefore, there is an urgent need to develop a cold heading machine safety material guide device that allows for easy adjustment of the guide angle to meet different usage requirements, provides good cushioning, and effectively reduces the speed of the material falling into the collection box through two guiding stages, minimizing impact damage. This would overcome the shortcomings of current practical applications and meet current needs. Utility Model Content
[0003] The purpose of this invention is to provide a safety stop device for cold heading machines to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A safety stop device for a cold heading machine includes a base plate, a primary guide box, a rotating shaft, a nut, a buffer mechanism, and a secondary guide box. A rotating shaft is fixed to both the left and right sides of the primary guide box, and the rotating shaft is rotatably connected to the base plate. The outer end of the rotating shaft is provided with an external thread, and the nut is installed on the outside of the external thread. A buffer mechanism is connected to the tail end of the primary guide box. The buffer mechanism includes a support plate, a buffer pad, a spring, and a damper. A buffer pad is fixed to the front side of the support plate, and the rear side of the support plate is elastically connected to the inner wall of the primary guide box via a spring. The damper is fixed to the primary guide box, and the movable end of the damper is fixed to the support plate. A discharge trough is provided below the support plate on the primary guide box. The secondary guide box is fixed to the lower side of the primary guide box.
[0006] Preferably, the substrate has multiple mounting holes for bolts to pass through.
[0007] Preferably, the cushioning pad is made of nitrile rubber.
[0008] Preferably, the included angle between the secondary guide box and the primary guide box is 40-50°.
[0009] The beneficial effects of this utility model are as follows: In use, the base plate of this cold heading machine safety blocking device is fixed to the discharge port of the cold heading machine with bolts. The nut is loosened, and the primary guide box and rotating shaft are rotated to adjust the tilt angle of the primary guide box to meet different discharge requirements. After adjustment, the nut is tightened and pressed against the base plate to prevent the rotating shaft from rotating. The material discharged from the cold heading machine discharge port slides along the primary guide box to the buffer mechanism and impacts the buffer pad. The buffer pad absorbs the impact force, and the spring deforms to buffer the impact. The damper absorbs and converts the impact force, thus reducing the impact force. After hitting the buffer pad, the material's speed is greatly reduced. Then, the material passes through the discharge chute and falls into the secondary guide box, where it slowly slides down to the collection box for collection. In summary, this utility model offers convenient adjustment of the guide angle to meet different usage requirements; it has good buffering performance, and the two-stage guiding effectively reduces the speed of the material falling into the collection box, minimizing damage caused by impact.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0016] Specific implementation examples are given below.
[0017] See Figures 1-3In this embodiment of the utility model, the safety blocking device for a cold heading machine includes a base plate 1, a primary guide box 2, a rotating shaft 3, a nut 4, a buffer mechanism 5, and a secondary guide box 6. The base plate 1 has multiple mounting holes 101 for bolts to pass through. During installation, the base plate 1 is fixed to the discharge port of the cold heading machine with bolts. A rotating shaft 3 is fixed to each of the left and right sides of the primary guide box 2. The rotating shaft 3 is rotatably connected to the base plate 1. The outer end of the rotating shaft 3 is provided with an external thread 301. The nut 4 is installed on the outside of the external thread 301. When the nut 4 is tightened and pressed against the base plate 1, the rotating shaft 3 cannot rotate. The tail end of the primary guide box 2 is connected to the buffer mechanism 5. The system includes: a support plate 501, a buffer pad 502, a spring 503, and a damper 504. The buffer pad 502 is fixed to the front side of the support plate 501. The buffer pad 502 is made of nitrile rubber, which gives it good elastic cushioning ability. The rear side of the support plate 501 is elastically connected to the inner wall of the primary guide box 2 through the spring 503. The damper 504 is fixed to the primary guide box 2, and the movable end of the damper 504 is fixed to the support plate 501. A discharge trough 201 is provided on the primary guide box 2 below the support plate 501. The secondary guide box 6 is fixed to the lower side of the primary guide box 2, and the included angle between the secondary guide box 6 and the primary guide box 2 is 40-50°.
[0018] Working principle: In use, the safety blocking device for the cold heading machine is as follows: the base plate 1 is fixed to the discharge port of the cold heading machine with bolts, the nut 4 is loosened, and the primary guide box 2 and the rotating shaft 3 are rotated to adjust the tilt angle of the primary guide box 2 to meet different discharge requirements. After adjustment, the nut 4 is tightened and pressed against the base plate 1 to prevent the rotating shaft 3 from rotating. The material discharged from the discharge port of the cold heading machine slides down the primary guide box 2 to the buffer mechanism 5 and hits the buffer pad 502. The buffer pad 502 absorbs the impact force, and at the same time, the spring 503 deforms to buffer the impact. The damper 504 absorbs and converts the impact force, thereby reducing the impact force. After hitting the buffer pad 502, the speed of the material is greatly reduced. Then the material passes through the discharge chute 201 and falls into the secondary guide box 6. The material then slowly slides down the secondary guide box 6 and is collected in the receiving box.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
