Description

Technical Field

[0001] The utility model relates to the technical field of metal material processing equipment, in particular to a stretching die. Background Art

[0002] In the metal material processing industry, stretching dies are an indispensable and important tool. Two die bodies are often combined relative to each other, and the two are combined together by setting a threaded clamp to form a complete stretching channel. When the blank is stuck, the size needs to be adjusted, or the stretching needs to be suspended to check the quality during the stretching process, the stretching die can be disassembled and opened to inspect the blank.

[0003] This traditional stretching die has serious stability problems when in use. Although it can be disassembled and opened, it lacks a stable clamping mechanism. When this single connection method is subjected to the force generated during the stretching process, it is difficult for the two mold bodies to maintain a tight fit, and gaps or misalignments are prone to occur, which reduces the overall stability of the stretching die and easily affects the normal progress of the stretching operation. To this end, we provide a stretching die to solve the above problems. Utility Model Content

[0013] 2. The utility model cooperates between the clamping mechanism, the hoop and the base. When it is necessary to disassemble mold one and mold two, the hoop only needs to be twisted upward to move the limit groove upward, and then the two cushions can cancel the clamping of mold one and mold two with the cooperation of the spring reaction force. This arrangement is more convenient for disassembling the stretching mold and improves the convenience of disassembly. The arrangement of the two cushions provides buffer protection when clamping and fixing the stretching mold, avoiding damage to the stretching mold due to excessive clamping force.

The ball 204 is squeezed by the limit groove 6. With the cooperation of the limit plate 205 and the spring 206, the two slide columns 202 are driven to be relatively close, so that the two soft pads 203 clamp and fix the mold 1 8 and the mold 2 9 respectively. This setting can maintain a tight fit between the mold 1 8 and the mold 2 9.

[0024] Furthermore, a first thread 3 is provided on the outer surface of the base 1 , and a placement groove 4 is provided on the top of the base 1 .

[0025] The first thread 3 is threadably connected with the second thread 7 to facilitate the up and down movement of the hoop 5. The placement groove 4 is provided to facilitate the placement of the mold 1 8 and the mold 2 9 therein for preliminary fixation.
