Technical Field

[0001] The present application relates to the technical field of brazing material extrusion, and in particular to a low-silver metal brazing rod extrusion device. Background Art

[0002] In certain areas, especially in electronic manufacturing and high-end industrial applications, low-silver metal brazing rods are gradually becoming the preferred option for connection materials due to their cost-effectiveness, good conductivity and environmental protection properties.

[0003] In the traditional application of low-silver metal brazing rods, manual shearing and preforming are common practices. This traditional method can no longer meet the stringent material processing standards of precision manufacturing. Problems such as inaccurate dimensional control and high labor costs frequently occur, affecting product quality and production efficiency.

[0007] In some embodiments, the cutting device includes a cutting blade and a cutting seat, and the cutting seat is disposed under the cutting blade.

[0008] In some embodiments, the cutting portion of the cutting seat is roughly V-shaped, and a cutting groove cut by the cutting blade is opened in the middle.

[0009] In some embodiments, the connecting block includes a first connecting block and a second connecting block, the first connecting block is disposed on the push rod, and the second connecting block is slidably connected to the first connecting block.

[0010] In some embodiments, a receiving groove for receiving a spring and a ball is formed on the inner wall of the second connecting block, and two ends of the spring are fixedly connected to the ball and the inside of the receiving groove respectively.

[0011] In some embodiments, the outer wall of the first connecting block is provided with a plurality of limiting grooves cooperating with the round balls.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to achieve. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that the combination of such technical solutions does not exist and is not within the scope of protection of this application.

[0021] In the embodiments of this application, please refer to Figure 1-3 As shown, the present application provides a low-silver metal brazing rod extrusion device, which mainly includes: a base; an extrusion head, which is arranged at one end of the base; a cutting device, which is arranged in front of the extrusion head and is used to cut the extruded brazing rod; a trigger device, including a connecting rod and a trigger switch, the connecting rod is horizontally arranged above the base, and the trigger switch is arranged on the connecting rod in plurality and is used to start the cutting device; a push rod, which is arranged on the base, and a connecting block extends from one part of its outer periphery, and the connecting block is used to start the push rod to toggle the trigger switch, thereby starting the cutting device.

[0022] Specifically, when the device starts to extrude the welding rod, the push rod will extrude towards the solder. While the push rod is extruding forward, the connecting block set on the push rod moves forward synchronously along the trajectory of the push rod's forward movement, and the cutting device will complete a cut on the brazing rod while contacting the trigger switch.

[0023] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0024] Specifically, the cutting device comprises a cutting blade and a cutting seat, wherein the cutting seat is arranged under the cutting blade, so that a cutting can be performed every time a part of the solder is extruded.

[0025] As an illustration, the cutting blade can cut the brazing material by means of a pneumatic cylinder.

[0026] More specifically, in order to make the cutting of the cutting device smoother and provide a force point for the cutting part, the cutting part of the cutting seat is roughly V-shaped in shape, and a cutting groove cut by the cutting blade is opened in the middle.

[0027] Reference Figure 3As shown, the connecting block includes a first connecting block and a second connecting block. The first connecting block is arranged on the push rod, and the second connecting block is slidably connected to the first connecting block. Such an arrangement enables the second connecting block to slide freely on the first connecting block.

[0028] Specifically, in order to achieve a fixed effect of the sliding connection between the second connecting block and the first connecting block, the inner wall of the second connecting block is provided with a receiving groove for accommodating a spring and a ball, and the two ends of the spring are respectively fixedly connected to the ball and the inside of the receiving groove.

[0029] Furthermore, the outer wall of the first connecting block is provided with a plurality of limiting grooves cooperating with the ball, so that the cylinder and the spring of the second connecting block can be fixed at multiple positions on the first connecting block, thereby achieving a multi-level positioning effect.

[0030] Reference Figure 3 As shown, the base is provided with two guide blocks for driving the connection block to contract or extend. When the push rod is about to move to the maximum stroke, the second connection block will abut against the guide block. Along the edge of the guide block, the second connection block will gradually contract inwardly. At the same time, the ball is forced to be squeezed into the accommodating groove, and then the spring is forced to be squeezed until the ball corresponds to another limit groove. The ball enters the limit groove under the action of the spring, achieving a fixing effect, so that the connection block enters a contracted state, and at the same time, the push rod will not interfere with the touch switch when it is reset;

[0031] Specifically, when the push rod is about to reset, the second connecting block will abut against another guide block, and along the edge of the guide block, the second connecting block will gradually move outward. At the same time, the ball is squeezed into the accommodating groove by force, and then the spring is driven to be squeezed by force until the ball corresponds to the initial limit groove. Under the action of the spring, the ball enters this limit groove, achieving a fixing effect and allowing the second connecting block to be extended again to a length that can activate the touch switch.

[0032] Furthermore, in order to better reset the second connection block when the push rod is reset, an extension block is provided on the outer wall of the second connection block for driving the connection block to extend.

[0033] So far, various embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed herein.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present application, and the aforementioned embodiments are only used to illustrate the technical solution of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions recorded in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not drive the essence of the corresponding technical solutions away from the spirit and scope of the technical solutions of the embodiments of the present application.
