Description

Technical Field

[0001] The utility model relates to the technical field of cold heading machine stripping, in particular to a cold heading machine stripping device. Background Art

[0002] In the cold heading process, core removal is a key link. Traditional stripping tooling devices are mainly divided into two methods: in-mold stripping and out-mold stripping. These two methods have their own limitations. In-mold stripping: This method requires the use of tungsten steel molds, which are more expensive, not only increasing the economic burden of production, but also may be more complicated in use and maintenance; out-mold stripping: Although this method may be relatively low in cost, its application range is limited. Due to the limitation of equipment travel, out-mold stripping is mainly suitable for shorter workpieces. For longer workpieces, this method is not applicable.

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The utility model discloses a material stripping device for a cold heading machine, such as Figure 1-4 As shown, it includes a base plate 120, which is roughly rectangular. Two pin seats 130 are connected to the base plate 120, two slide pins 140 are connected between the two pin seats 130, and a slide 150 is slidably connected to the two slide pins 140, and the slide 150 is connected to the unloading plate 160.

[0026] The unloading plate 160 is provided with a unloading hole 161, and the cold heading machine punch 200 is driven by the stamping equipment (not shown in the figure). The punch 200 passes through the unloading hole 161 to stamp the product 300, and after the core of the product 300 is punched out, the punch 200 is driven by the stamping equipment to withdraw from the unloading hole 161, and the product 300 will be blocked by the unloading plate 160 and separated from the punch 200, and fall due to gravity, completing the material withdrawal.

[0027] Furthermore, two spring pins 180 are connected between the two pin seats 130. The structure of the slide seat 150 is as follows: Figure 2 As shown, the slide 150 is provided with a through hole corresponding to the spring pin 180, and the spring 170 is arranged on the spring pin 180 by being sleeved through the through hole. The spring pin 180 is slidably connected to the slide 150, and the slide 150 is also provided with a spring accommodating groove 131 corresponding to the spring 170. The spring accommodating groove 131 is obtained by expanding the through hole, and a step surface is provided in the spring accommodating groove 131. The spring 170 is sleeved on the spring pin 180 and is arranged in the spring accommodating groove 131 at the same time. The spring 170 can be guided to be compressed through the spring pin 180 and the spring accommodating groove 131.

[0028] When the cold heading machine punch 200 passes through the discharge hole 161 to punch the product 300, the punch 200 can drive the discharge plate 160 to squeeze the spring 170. The spring 170 can buffer and protect the stamping die and the punch 200. The addition of the spring 170 also makes the entire device more flexible and adaptable, and can cope with workpieces of different sizes and shapes, thereby expanding the application range of the device.

[0029] Furthermore, if Figure 3 As shown, slide grooves 132 are opened on both sides of the base plate 120, and the slide seat 150 is connected with a slide column 133 corresponding to the slide groove 132; when the slide seat 150 slides along the slide seat pin shaft 140, the slide column 133 slides in the slide groove 132. Through the cooperation between the slide groove 132 and the slide column 133, the slide seat 150 can be better guided to slide along the slide seat pin shaft 140, and it is not easy to deviate, thereby increasing the safety and reliability of the entire device and extending the service life of the entire device.

[0030] Furthermore, if Figure 4As shown, a discharge hole 161 is inlaid with a discharge pad 162 on the side close to the product 300. The discharge pad 162 is roughly annular. The discharge plate 160 is provided with an embedding groove 162a along the discharge hole 161. The discharge pad 162 is connected to the discharge plate 160 through the embedding groove 162a to form a whole. The discharge pad 162 is made of high-strength material. When subjected to the impact of the product 300, it can protect the discharge hole 161 from deformation and damage.

[0031] Principle of the utility model: when in use, the whole device is connected to the base 110 through the bottom plate 120 and fixed on the cold heading machine. When working, the cold heading machine punch 200 passes through the discharge pad 162 to complete the punching and core removal action. When the punch 200 exits the discharge pad 162, the product 300 is blocked outside the discharge pad 162 and falls due to gravity to complete the material withdrawal. The device introduces a movable spring 170 and a discharge plate 160, and has a simple structure to facilitate material withdrawal, has a wide range of applications, and helps to improve production efficiency and reduce production costs.
