Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing equipment, in particular to a pipe fitting positioning device for punching holes in pipe fittings. Background Art

[0002] Punching round tubes is a common pipe processing technology. A punching machine is usually used for punching pipes. The operator fixes the pipe on the positioning device of the punching machine and punches it into shape. Waste will be generated during the punching process. The positioning device of the existing punching machine is generally provided with a waste drop hole for the waste to fall and discharge. The drop hole is directly connected to the waste collection port, and the waste is directly dropped and collected. However, in this waste drop method, the operator cannot observe the internal drop. Since during the stamping operation, there may be waste sticking to the punch or blocking in the drop hole. Therefore, in the case of unknown drop, there is a high possibility of waste drop error affecting the punch stamping or damaging the punch. For this reason, we provide a pipe positioning device for pipe punching. By changing the waste collection method, it is easy for the operator to observe the waste drop during operation and clean up the waste caused by the drop error in time. Utility Model Content

[0003] The utility model aims to provide a pipe positioning device for pipe punching, so as to facilitate operators to observe the waste material falling during the pipe punching operation and clean up the waste material caused by the wrong falling material in time.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pipe positioning device for punching pipes, comprising a die base, a guide sleeve is arranged on the top of the die base, the die base is slidably arranged with the punch through the guide sleeve, a die core is horizontally arranged on the die base in a direction perpendicular to the punch, a cutting edge and a blanking hole are arranged on the die core in sequence from top to bottom along the direction of movement of the punch, a template is arranged on the die base along the circumference of the die core, the template comprises left and right long templates and upper and lower short templates, the die core and the template form a pipe positioning cavity, a conical guide head is arranged at the tail end of the die core, a horizontal feeding channel is arranged at the bottom of the die base corresponding to the bottom of the die core, and a belt conveyor line is arranged in the feeding channel.

[0005] Preferably, the diameter of the blanking hole is larger than the diameter of the cutting edge.

[0006] Preferably, the template and the mold core are detachably mounted on the mold base via bolts.

[0007] Preferably, an eccentric wheel is arranged at the front end of the long template, the axial direction of the rotating shaft of the eccentric wheel is parallel to the axial direction of the punch, the eccentric wheel is rotatable around the rotating shaft, and the circumference of the eccentric wheel is offset to the side close to the mold core when the eccentric wheel rotates.

[0008] Preferably, the die base is fixedly mounted on the punching machine via a positioning fixture.

[0009] Preferably, one end of the belt conveyor line extends to the front side of the die base, and the other end extends to the rear of the die base. A waste box is arranged on the back of the punching machine, and the output end of the belt conveyor line extends above the waste box.

[0010] The utility model has the following beneficial effects:

[0011] 1. The pipe positioning cavity formed by the die base, die core and die plate can well accommodate the positioning pipes, which is convenient for pipe loading. When punching, waste will not jump out between the pipes and the blanking holes, and the operation is safe.

[0012] 2. After the punched waste is taken out of the pipe, it falls into the belt conveyor line and is discharged from the feeding channel. The dropping position is convenient for the operator to observe the specific waste discharge situation and to clean up the waste caused by the error in dropping in time;

[0013] 3. After entering the pipe positioning cavity, the pipe is clamped by the left and right eccentric wheels, the positioning is stable, and the eccentric wheels rotate along the feeding direction of the pipe to ensure that the clamped pipe does not rotate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-3As shown, the utility model provides a technical solution: a pipe positioning device for punching pipes, comprising a die base 1, the die base 1 is fixedly mounted on a punching machine 8 through a positioning fixture 7, a guide sleeve 2 is arranged on the top of the die base 1 to ensure stable punching of a punch 3, and the die base 1 is slidably arranged with the punch 3 through the guide sleeve 2;

[0020] A die core 4 is horizontally arranged on the die base 1 along the direction perpendicular to the punch 3. The die core 4 is detachably mounted on the die base 1 through bolts. A cutting edge 41 and a blanking hole 42 are arranged on the die core 4 in sequence from top to bottom along the moving direction of the punch 3. The punch 3 cooperates with the cutting edge 41. When punching, the waste material moves into the blanking hole 42 under the pressure of the punch 3. The diameter of the blanking hole 42 is larger than that of the cutting edge 41 for easy blanking.

[0021] A template 5 is arranged on the die base 1 along the circumference of the die core 4. The template 5 is detachably mounted on the die base 1 by bolts. The template 5 includes left and right long templates 51 and upper and lower short templates 52. The short template 52 makes way for the cutting edge 41. An eccentric wheel 510 is arranged at the front end of the long template 51. The axial direction of the rotating shaft of the eccentric wheel 510 is parallel to the axial direction of the punch 3. The eccentric wheel 510 can rotate around the rotating shaft, and the circumference of the eccentric wheel 510 is offset to the side close to the die core 4 when the eccentric wheel 510 rotates.

[0022] The mold core 4 and the template 5 form a pipe positioning cavity. A conical guide head 43 is provided at the tail end of the mold core 4. When the pipe is fed, the conical guide head 43 is used to guide the pipe to be sleeved on the mold core 4 and positioned in the pipe positioning cavity. When the pipe is fed, the outer peripheral surface contacts the peripheral surface of the eccentric wheel 510, and there is friction. During the pipe feeding process, the eccentric wheel 510 is driven to rotate. When the eccentric wheel 510 rotates, the peripheral surface is offset to the side close to the mold core 4 to gradually clamp the pipe, which can replace the handheld stable pipe. When the pipe is taken out, the eccentric wheel 510 is driven to rotate in the opposite direction, and the clamping force can be loosened. The eccentric wheel 510 can be a rubber wheel with elasticity, but is not limited thereto.

[0023] A horizontal feeding channel 11 is arranged below the mold core 4 at the bottom of the mold base 1, and a belt conveyor line 6 is arranged in the feeding channel 11. One end of the belt conveyor line 6 extends to the front side of the mold base 1, and the other end extends to the rear of the mold base 1. A waste box 9 is arranged on the back of the punching machine 8, and the output end of the belt conveyor line 6 extends to the top of the waste box 9. The waste discharged by the belt conveyor line 6 is output to the waste box 9, so as to ensure that the punching machine 8 is clean and tidy, and the waste falling situation is visible, so as to facilitate timely cleaning of the waste caused by falling errors.
