Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of wire blank welding seam processing, in particular to a wire blank butt welding and stamping scar removal device. BACKGROUND

[0002] In the production process of pipe fittings or wire blanks, in order to obtain a wire blank with sufficient length and continuity, the ends of different sections of the wire blank often need to be butt welded. During the butt welding operation, welding marks are left on the welding site, which are generally protrusions in the circumferential direction of the wire blank. In order to ensure the subsequent use of the wire blank, the welding marks on the welded site need to be processed.

[0003] The traditional method is generally to remove by manual grinding, but this method is labor-intensive, low in work efficiency, and cannot guarantee the uniformity of quality. SUMMARY

[0004] In order to solve the problem of inconvenient and low efficiency in processing the welding seam scar after butt welding of the wire blank in the prior art, the present application provides a wire blank butt welding and stamping scar removal device. Four synchronous stamping punches can remove the scar protruding in the circumferential direction of the wire blank at the welding site at one time, thereby improving the processing efficiency of the scar.

[0005] The present application provides a wire blank butt welding and stamping scar removal device, which solves the technical problem by a technical scheme including a stamping component and a first clamping and fixing component. The clamping and fixing component includes a left clamping unit and a right clamping unit. The left clamping unit includes a left lower fixed plate and a left upper movable plate. The right clamping unit includes a right lower fixed plate and a right upper movable plate. The stamping component includes a left upper punch, a left lower punch, a right upper punch, and a right lower punch. The left upper punch is installed on the left upper movable plate. The left lower punch is installed on the left lower fixed plate. The right upper punch is installed on the right upper movable plate. The right lower punch is installed on the right lower fixed plate. The center lines of the left upper punch and the left lower punch and the center lines of the right upper punch and the right lower punch form a cross shape. The left upper punch, the left lower punch, the right upper punch, and the right lower punch are synchronously stamped along the axial direction of the wire blank.

[0006] In the present technical solution, the left clamping unit and the right clamping unit are used to simultaneously fix the two sides of the butt welding site of the wire blank, so that the working site is located in the middle position between the left clamping unit and the right clamping unit, thereby ensuring the stability of the operation. Four punches arranged in a cross shape are used to synchronously stamp the scar from both sides in pairs during the stamping of the scar, which can ensure the stability of the wire blank under stress during stamping and avoid damaging the wire blank. Moreover, the scar can be removed by stamping, which can greatly improve the processing efficiency of the scar.

[0007] Preferably, V-shaped guide grooves are formed on the left lower fixed plate and the left upper movable plate, the right lower fixed plate and the right upper movable plate, and the bottom of the V-shaped guide groove is formed with an arc-shaped part which is profiled with the surface of the wire blank. In operation, the V-shaped guide groove facilitates positioning of the wire blank and better fixation of the wire blank.

[0008] Preferably, the left lower fixed plate and the left upper movable plate are arranged in a staggered manner in the horizontal direction, the right side surface of the left lower fixed plate and the left side surface of the left upper movable plate are in the same plane; the right lower fixed plate and the right upper movable plate are arranged in a staggered manner in the horizontal direction, the left side surface of the right lower fixed plate and the right side surface of the right upper movable plate are in close contact with each other. The staggered arrangement structure ensures that wire blanks of different diameters can be clamped and fixed, and the coplanar one side surface of the upper and lower fixed plates can reduce the deformation of the workpiece during clamping due to shearing force.

[0009] Preferably, the cross section of the left upper punch, the left lower punch, the right upper punch and the right lower punch is a 90° sector structure, and the inner side surface of the left upper punch, the left lower punch, the right upper punch and the right lower punch is arc-shaped and coplanar with the arc surface of the arc-shaped part of the installation base. The four punches together form a ring-shaped stamping area, which can maximize the one-time removal of the scar, and the arc-shaped inner side surface can make the punch better fit the surface of the wire blank and improve the scar cleaning quality.

[0010] Preferably, the stamping action of the left upper punch, the left lower punch, the right upper punch and the right lower punch is controlled by the same set of pneumatic system. This facilitates the synchronous action of the four punches.

[0011] Preferably, in the initial state, the right side stamping surface of the left upper punch and the left lower punch is in the same plane, and the left side stamping surface of the right upper punch and the right lower punch is in the same plane. This ensures that the scar is contacted at the same time during stamping and ensures the force balance of the wire blank during stamping.

[0012] Preferably, it further comprises a second clamping and fixing component, the second clamping and fixing component comprises a second clamping unit located on both sides of the first clamping and fixing component, and the clamping center line of the second clamping unit is collinear with the clamping center line of the left clamping unit and the right clamping unit. This further ensures the stability of the wire blank.

[0013] Preferably, the second clamping unit comprises a lower fixed die and an upper movable die, and the lower fixed die and the upper movable die are both provided with arc-shaped grooves. The lower fixed die and the upper movable die are in a structure of opening and closing, which facilitates the workpiece to enter the working position, and the structure of the arc-shaped groove facilitates the positioning of the workpiece.

[0014] Preferably, the lower fixed mold has lower guide plates at both ends, and the upper movable mold has upper guide plates at both ends. Both the upper and lower guide plates have V-shaped guide grooves, the bottom of which communicates with the arc-shaped groove. The V-shaped guide grooves facilitate the entry of the wire blank and effectively position and clamp the workpiece.

[0015] Preferably, the upper guide plate is horizontally distributed outside the lower guide plate, and one side of it is coplanar with the outer side of the lower guide plate. This also reduces the deformation of the wire rod.

[0016] In summary, the application of the technical solution of the present invention has at least the following beneficial effects:

[0017] 1. With four synchronously stamping punches, the circumferentially protruding scars at the welding part of the wire blank can be removed in one go, which improves the scar treatment efficiency.

[0018] 2. By designing the first clamping and fixing component and the second clamping and fixing component, the wire blank can be clamped at multiple points to ensure a good clamping effect;

[0019] 3. The cross-shaped distribution of the stamping head can ensure stability during the stamping process, ensure force balance, and reduce the vibration and deformation of the wire blank. Attached Figure Description
