Problems solved by technology

[0002] A "Ω"-shaped pipe clamp is used in machinery, construction and other fields, mainly for fastening some pipe fittings. Most of the molds used to process this type of pipe clamp require more than two moldings to complete the entire "Ω"-shaped pipe. The processing of hoops makes the entire processing efficiency very low, and the pass rate after processing will also be reduced due to multiple moldings

Embodiment Construction

[0008] Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail:

[0009] Such as figure 1 As shown, in the stamping of "Ω"-shaped pipe collar, during the stamping process, the blank 3 is placed in the positioning block 4, and the cylindrical punch 2 on the punch is sleeved on the die handle 1 and punches downward. 6 is hinged on the lower mold base 7, and the cylindrical punch 2 bears against one end of the swinging die 6 so that the swinging die 6 swings to the middle to extrude the blank 3 to form around the cylindrical punch 2; when the cylindrical punch 2 rises , the swinging die 6 returns to the initial position under the action of the elastic restoring force of the spring 5, and removes the formed "Ω"-shaped pipe collar from the cylindrical male die 2.

[0010] What is described above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under...

Abstract

The invention discloses a pipe hoop stamping die in the field of dies. The pipe hoop stamping die comprises a cylindrical male die and a lower die seat. The cylindrical male die is radially connected with a die shank. A pair symmetrical swing female dies is hinged to the lower die seat. A spring is connected between the forming end of each swing female die and the lower die seat. The cavity formed by the swing female dies is matched with the cylindrical male die. The lower die seat is further provided with positioning blocks for positioning blanks. The pipe hoop stamping die for machining 'omega'-shaped pipe hoops is simple to operate and high in efficiency. During machining, a user only needs to place the blanks in the positioning blocks and starts a stamping machine, the blanks are formed at one step under the action of the cylindrical male die and the swing female dies, defective products caused by multiple forming can be avoided, and machining yield is increased.

Description

technical field [0001] The invention belongs to the field of moulds, and in particular relates to stamping dies for pipe hoops. Background technique [0002] A "Ω"-shaped pipe clamp is used in machinery, construction and other fields, mainly for fastening some pipe fittings. Most of the molds used to process this type of pipe clamp require more than two moldings to complete the entire "Ω"-shaped pipe. The processing of the hoop makes the entire processing efficiency very low, and the pass rate after processing is also reduced due to multiple moldings. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stamping die for pipe collars with high processing efficiency and high pass rate. [0004] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: the stamping die for pipe collars includes a cylindrical punch and a lower die holder, the cylindrical...
