Description

Technical Field

[0001] The utility model relates to the technical field of pipe clamps, in particular to a pipe clamp for metal processing. Background Art

[0002] After punching a metal pipe, it is necessary to deburr the punched position. A common deburring scraper is used for scraping, and the pipe needs to be clamped and limited to a certain extent. The traditional operation method is to clamp it with a general-purpose fixture such as a bench vise, but there are several deficiencies;

[0003] 1. The operation of the bench vise is cumbersome when clamping and pushing materials, and the work efficiency is low;

[0004] 2. The clamping surface of the bench vise is rough, and clamping a pipe fitting with requirements for surface roughness will damage its surface roughness;

[0005] 3. The length of the clamping surface of the bench vise is limited, and it cannot achieve a good clamping effect on a pipe fitting with a large length. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is: in order to overcome the above problems, a pipe clamp for metal processing is provided, which solves the above problems.

[0007] The utility model solves its technical problems by adopting the following technical solutions:

[0008] A pipe clamp for metal processing includes a base with bolt fixing feet, and the bolt fixing feet are fixed on the table by bolts. Two clamping pipe clamps are arranged on the base at intervals for clamping a metal pipe. The clamping pipe clamp includes a base table fixed on the base, and also includes four small arm rods, a top clamping plate, two large arm rods and two side clamping plates with articulated tail seats. One end of the small arm rod is articulated with the top clamping plate and the other end is articulated with the large arm rod, and the large arm rod is articulated with the base table. The other end of the large arm rod is articulated with the articulated tail seat. The side clamping plate and the top clamping plate are in an arc structure, and a clamping ring structure is formed after they are closed, which can well clamp the outside of the metal pipe. And a magnetic iron bar is fixedly arranged on the lower end surface of the top clamping plate, and the magnetic iron bar is inserted into the base. Two symmetric electromagnetic iron blocks are arranged in the base. A side compression spring is arranged between the electromagnetic iron block and the base. When the electromagnetic iron block is electrified, it can magnetically fix the magnetic iron bar to keep the clamping pipe clamp in a clamping state. A base table for controlling the electromagnetic iron block is fixedly arranged on the base. When it is necessary to release the clamping, the electromagnetic iron block can be powered off through the base table.

[0009] Preferably, a quick return spring is fixedly arranged inside the base. The upper end of the quick return spring abuts against the lower end surface of the armature bar, and the spring force of the quick return spring is greater than that of the side pressure spring. When the electromagnet block loses magnetic attraction, the quick return spring automatically jacks up the armature bar to quickly release the clamping, which is more convenient and efficient.

[0010] Preferably, anti-slip rubber sheets are fixedly arranged on the inner walls of the side clamping plates and the top clamping plate, which can play a role in stabilizing and anti-slip when clamping a metal pipe, and ensure that the clamping force meets the requirement of deburring.

[0011] Preferably, a push-button switch is fixedly arranged inside the base. The push-button switch is located directly below the armature bar. When the metal pipe is pressed down, the top clamping plate is pushed downward and when the armature bar reaches a specified position, the push-button switch is triggered to energize the electromagnet block to make it magnetic, thereby automatically locking the clamping state of the clamping type pipe clamp, which is more convenient.

[0012] The advantages and positive effects of the present utility model are:

[0013] 1. The clamping is convenient. By pressing the pipe fitting, the side clamping plates are surrounded and locked to complete the clamping, and the push-button switch can be triggered by the armature bar to automatically start the electromagnet block to complete the locking, which is very convenient and efficient.

[0014] 2. After the electromagnet block is powered off through the base platform, the quick return spring will quickly bounce up the armature bar to quickly release the clamping state of the pipe, and the pipe is still supported by the top clamping plate, which is convenient for taking, and is very user-friendly.

Detailed implementation mode

[0021] Now, the present utility model will be further described in detail with reference to the attached drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model. The following is a further detailed description of the embodiments of the present utility model with reference to the attached drawings:

[0022] As Figures 1-4 shown, a pipe clamp for metal processing according to the present utility model includes a base 16 with bolt fixing feet 21, and the bolt fixing feet 21 are fixed on the tabletop by bolts. Two clamping type pipe clamps 22 are arranged at intervals on the base 16 for clamping and holding metal pipes. The clamping type pipe clamp 22 includes a base platform 23 fixed on the base 16, and also includes four forearm rods 13, a top clamping plate 14, two boom rods 12 and two side clamping plates 10 with articulated tailstocks 11. One end of the forearm rod 13 is articulated with the top clamping plate 14 and the other end is articulated with the boom rod 12, and the boom rod 12 is articulated with the base platform 23. The other end of the boom rod 12 is articulated with the articulated tailstock 11. The side clamping plate 10 and the top clamping plate 14 are in an arc structure, and a clamping ring structure is formed after they are closed, which can well clamp the outside of the metal pipe. And a armature bar 15 is fixedly arranged on the lower end surface of the top clamping plate 14. The armature bar 15 is inserted into the base 16, and two symmetrical electromagnet blocks 18 are arranged in the base 16. A side compression spring 17 is arranged between the electromagnet block 18 and the base 16. When the electromagnet block 18 is energized, it can magnetically attract and fix the armature bar 15 to keep the clamping type pipe clamp 22 in a clamping state. A base platform 23 for controlling the electromagnet block 18 is fixedly arranged on the base 16. When it is necessary to release the clamping, the electromagnet block 18 can be powered off through the base platform 23.

[0023] Preferably, a quick return spring 19 is fixedly arranged in the base 16. The upper end of the quick return spring 19 abuts against the lower end surface of the armature bar 15, and the spring force of the quick return spring 19 is greater than the spring force of the side compression spring 17. When the magnetic attraction of the electromagnet block 18 is lost, the quick return spring 19 automatically jacks up the armature bar 15 to quickly release the clamping, which is more convenient and efficient.

[0024] Preferably, anti-slip rubber sheets are fixedly arranged on the inner walls of the side clamping plates 10 and the top clamping plate 14, which can play a role in stabilizing and anti-slip when clamping metal pipes, and ensure that the clamping force meets the requirements of deburring.

[0025] Preferably, a push-button switch 20 is fixedly arranged in the base 16. The push-button switch 20 is located directly below the armature bar 15. When the metal pipe is pressed down, the top clamping plate 14 is pushed downward. When the armature bar 15 reaches a specified position, the push-button switch 20 is triggered, causing the electromagnet block 18 to be energized and magnetized, thereby automatically locking the clamping state of the clamping type pipe clamp 22, which is more convenient.

[0026] During specific implementation, the metal pipe is pressed on the top clamping plate 14 and then pressed down. Through the hinge rod structure, the side clamping plates 10 are buckled inward to cooperate with the top clamping plate 14 to clamp the metal pipe. Then the armature bar 15 is pressed down to trigger the push-button switch 20, and the electromagnet block 18 generates magnetic attraction after being energized to fix the armature bar 15, completing the clamping, which is convenient for multi-hole deburring. After the processing is completed, the energization of the electromagnet block 18 is released through the base table 23, and then the quick return spring 19 quickly pushes up the armature bar 15, enabling the metal pipe to be released from the clamping, and the metal pipe is pushed up by the top clamping plate 14 for convenient taking, which is very convenient and reasonable.

[0027] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners obtained by those skilled in the art based on the technical solutions of the present invention also fall within the protection scope of the present invention.
