The technical scheme of the utility model is further described below with reference to fig. 1-2.
The bending die for the curved front frame of the television comprises a base 1, a female die 2, a punch assembly 3, a first fixing assembly 4 and a second fixing assembly 5, wherein the female die 2, the punch assembly 3, the first fixing assembly 4 and the second fixing assembly 5 are arranged on the base 1. The base 1 is horizontally installed so as to horizontally carry an aluminum front frame and other components, the female die 2 is horizontally detachably connected to the base 1, and a groove 231 for molding the aluminum front frame is formed in the female die 2. The punch assembly 3 comprises a punch 31 fitted with the recess 231 and a second hydraulic cylinder 32 for driving the punch 31 to move, a piston rod of the second hydraulic cylinder 32 is connected with the punch 31, the punch 31 is arranged at a position horizontally opposite to the recess 231 of the die 2, and when punching the aluminum front frame raw material, the aluminum front frame raw material stands between the punch 31 and the die 2. The first fixing component 4 and the second fixing component 5 are respectively located at two sides of the notch of the groove 231, and before the punch 31 punches, the first fixing component 4 and the second fixing component 5 respectively abut against two ends of the aluminum front frame raw material to assist in molding the aluminum front frame raw material.
When the bending die is used, the aluminum front frame raw material is erected on the base 1, and two ends of the aluminum front frame raw material are attached to the notch of the groove 231 of the female die 2 and fixed through the first fixing component 4 and the second fixing component 5. When the aluminum front frame raw material is bent into a curved surface front frame, the second hydraulic cylinder 32 drives the punch 31 to horizontally move towards one side of the groove 231 until the aluminum front frame raw material is bent into the groove 231, so that the aluminum front frame raw material is formed into the curved surface aluminum front frame; the punch 31 is horizontally moved to the initial position after molding, and the curved aluminum front frame is removed. The above bending die is formed by horizontal stamping, and has no other structure in the vertical direction to affect the feeding and discharging of the aluminum front frame, so that the blockage is avoided, the feeding and discharging efficiency of the aluminum front frame is effectively improved, and the forming efficiency of the curved aluminum front frame is improved. In addition, the bending die is simple in structure, convenient to manufacture and assemble, and low in manufacturing cost.
