Description

Technical Field

[0001] The utility model relates to the field of cold heading machines, in particular to a punch position regulating mechanism of a cold heading machine. Background Art

[0002] ‌The working principle of the cold heading machine‌ is the process of gradually forming a specific shape from a metal wire at high speed without heating through a series of replicated dies, hammers and punches. Specifically, the cold heading machine feeds the wire into the machine, cuts it into appropriate lengths, and then hammers and forms it. The entire process does not involve heating or processing the metal, but completes the forming at room temperature. ‌

[0003] The punch of the cold heading machine is a key component of hammering. It will deviate or wear under long-term hammering, resulting in the punch position not being able to accurately hammer the mold. Inaccurate punch position will lead to abnormal parts and unloading. The processed products may be inaccurate in size or even have defects such as cracks. Therefore, the position of the punch is related to the quality of the product. After the existing punch is deviated or worn, it can only be reset by knocking on the relevant parts or replacing the punch, which increases the workload and greatly affects the progress of production.

DETAILED DESCRIPTION

[0012] The present invention is specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the protection scope of the present invention.

[0013] like Figure 1 , Figure 2As shown, this embodiment discloses a position adjustment mechanism of a punch 2 of a cold heading machine, comprising a frame 1, a punch 2, and a front push rod 3. The punch 2 is arranged at the end of the front push rod 3. The frame 1 is provided with a die seat 4 for its telescopic movement corresponding to the punch 2. The die seat 4 can be adjusted up and down and left and right. The specific structure is as follows: a front side plate 5 is installed on the frame 1, and an "L"-shaped hanging plate 51 is connected to the upper end of the front side plate 5. A hanging groove is provided on the hanging plate 51. An adjustment plate 6 that moves up and down along the front end surface of the front side plate 5 is provided. A Z-direction adjustment screw 7 is provided at the upper end of the adjustment plate 6. The Z-direction adjustment screw 7 is adjustably hung on the hanging groove through a washer and a nut. The die seat 4 is connected to the adjustment plate 6. Guide holes are respectively provided for the punch 2 to pass through, and through holes are respectively provided at the upper and lower ends of the die seat 4. A sleeve 10 is provided in the through hole. A fixing bolt 20 passes through the sleeve 10 and is connected to the adjustment plate 6. Horizontally placed X-direction adjusting screws 8 are respectively screwed on both sides of the die seat 4. The ends of the two X-direction adjusting screws 8 are respectively inserted into the through holes and abut against the sleeve 10. Since the fixing bolts are fixed, unscrewing the X-direction adjusting screws 8 loosens one side of the sleeve 10, and tightening the X-direction adjusting screws 8 on the other side pushes the sleeve 10 to move to the other side. A gap is left between the sleeve 10 and the through hole of the die seat 4, and the sleeve 10 is fixedly sleeved on the fixing bolt 20, so that the die seat 4 can be adjusted by moving left and right along the fixing bolt 20. Figure 1 In the figure, no X-direction adjusting screw 8 is provided at the lower end of the die seat 4, so the adjustment method of the die seat 4 is similar to the left and right arc swing adjustment of the die seat 4. Of course, an X-direction adjusting screw 8 can also be provided at the lower end of the die seat 4 for left and right translation adjustment.

[0014] The frame 1 is provided with a channel length adjusting device 30 corresponding to the front push rod 3, so that the punch 2 installed at the end of the front push rod 3 can adjust its initial point in the die seat 4 through this structure. For example, when the punch 2 is punching, a deeper hole can be punched according to the hole depth requirement. The channel at the position of the front push rod 3 can be shortened through the channel length adjusting device 30, so that the stroke of the punch 2 is longer to meet the punching depth requirement.

[0015] The channel length adjustment device 30 includes a fixed inclined plate 301 and an adjusting inclined plate 302. The fixed inclined plate 301 is fixed on the frame. The fixed inclined plate 301 and the adjusting inclined plate 302 are respectively provided with channels for the front push rod 3 to pass through. The diameter of the channel is larger than the outer diameter of the front push rod and a large margin is left. The fixed inclined plate 301 is provided with a first inclined surface, and the adjusting inclined plate 302 is provided with a second inclined surface that fits and slides with the first inclined surface. The specific structure can be provided with a guide groove and a guide block between the first inclined surface and the second inclined surface. The structure slides relatively, and a threaded Y-axis adjusting bolt 9 is provided at the upper end of the fixed inclined plate 301. The end face of the Y-axis adjusting bolt 9 can be rotatably connected to the adjusting inclined plate 302. After the Y-axis adjusting bolt 9 is rotated, the adjusting inclined plate 302 can slide along the inclined surface of the fixed inclined plate 301, so that the widths on both sides of the fixed inclined plate 301 and the adjusting inclined plate 302 can be changed, thereby changing the length of the channel, so that the ejection stroke distance of the punch 2 can be adjusted, which can make the operation more convenient.

[0016] By adopting the above technical scheme, the adjustment plate 6 can be moved up and down for adjustment through the operation of the Z-axis adjustment screw 7, thereby driving the up and down adjustment of the die seat 4. The X-axis adjustment screw 8 can be sleeved on the left and right position of the sleeve 10, thereby adjusting the left and right position of the die seat 4. The Y-axis adjustment bolt 9 in the channel length adjustment device 30 can adjust the position of the front push rod 3, thereby adjusting the axial position of the punch 2. In this way, the technical effect of convenient and reliable adjustment of the punch 2 is achieved, ensuring that the position of the punch 2 can accurately hammer the mold, thereby greatly improving work efficiency and product quality.

[0017] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
