Description

Technical Field

[0001] The utility model belongs to the technical field of T-shaped copper tube processing, in particular to a T-shaped copper tube stamping forming die. Background Art

[0002] Copper tubes are pressed and drawn seamless tubes. They have good electrical and thermal conductivity. They are the main materials for the conductive and heat dissipation accessories of electronic products, and they have become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses. Copper tubes have strong corrosion resistance, are not easy to oxidize, and are not easy to react chemically with some liquid substances. They are easy to bend. At the port connection of some pipes, special T-shaped copper tubes are required. Therefore, in order to facilitate the processing of T-shaped copper tubes, corresponding stamping molds will be used.

[0003] However, when the existing stamping mold is used, the molds cannot be stamped quickly, which reduces the stamping efficiency of the T-shaped copper tube. At the same time, the mold will be worn after being used for a long time and being stamped too many times. Since it does not have the function of easy disassembly, it cannot be quickly replaced. To this end, we provide a T-shaped copper tube stamping mold to solve the above problems. Utility Model Content

[0028] 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 of 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. Specific embodiment 1

[0029] See also Figures 1 to 7The utility model is a T-shaped copper tube stamping and forming die, which controls the stamping work between the upper die 4 and the lower die 3 to facilitate the stamping and forming of the T-shaped copper tube, and controls the positioning bar 6 to move so as to quickly disassemble and replace the lower die 3.

[0030] Specifically, the punch block 1 and the top plate 2 located directly above it; a placement opening 101 is opened in the middle of the upper end surface of the punch block 1, a lower mold 3 is arranged inside the placement opening 101, a T-shaped groove 301 is opened in the middle of the upper end surface of the lower mold 3, and the upper end surfaces of the punch block 1 located on the left and right parts of the placement opening 101 are opened with notches 104, and the bottom surfaces of the notches 104 are opened with ears 102 connected to the inside of the placement opening 101, and the left and right end surfaces of the lower mold 3 are fixed with An ear block 302 is flush with the bottom surface of the recess 104, and the ear block 302 is arranged in the corresponding ear opening 102. A positioning strip 6 flush with the upper end surface of the punching block 1 is arranged inside the recess 104 located at the upper end surface of the ear block 302. An upper mold 4 is arranged directly above the lower mold 3. A T-slot 2 401 is opened on the lower end surface of the upper mold 4 in the same upper and lower positions as the T-slot 1 301. A punching cylinder 201 is fixed at the middle position of the upper end surface of the top plate 2.

[0031] The operation process of this embodiment is as follows: through the setting and use of the above-mentioned structure, the corresponding raw material is set at the position of the lower mold 3, and the stamping cylinder 201 is controlled to work, thereby the stamping cylinder 201 controls the upper mold 4 to move downward, and stamps the raw material on the lower mold 3, so that the quota of the T-slot 1 301 and the T-slot 2 401 is used to stamp the raw material into a corresponding T shape. At the same time, when the lower mold 3 needs to be replaced, the positioning strip 6 can be moved in the opposite direction of the ear block 302, and then the positioning strip 6 will be moved out at the upper end surface position of the ear block 302. At this time, the lower mold 3 is taken out from the internal position of the placement port 101, and the ear block 302 can be taken out from the inside of the ear port 102, so as to replace the lower mold 3. Specific embodiment 2

[0032] See also Figure 2 , Figure 3 , Figure 4 and 7 On the basis of the specific embodiment 1, the spring 603 limits the adjustment block 601 so that the positioning strip 6 can be stably located above the ear opening 102, thereby abutting and positioning the ear block 302 to ensure the stable assembly of the lower mold 3.

[0033] Specifically, a positioning rod 103 flush with the bottom surface of the recess 104 is fixed to the bottom surface of the ear opening 102, the ear block 302 is sleeved on the circumferential side of the positioning rod 103 through the positioning hole 303, and adjustment openings 105 are provided on the bottom surface of the recess 104 located in the front and rear of the ear opening 102. Adjustment blocks 601 slidably set in the adjustment opening 105 are fixed to the front and rear parts of the lower end surface of the positioning strip 6, and adjustment rods 106 are fixed to the left and right end surfaces of the adjustment opening 105. The adjustment blocks 601 are slidably sleeved on the adjustment rods 106 through the adjustment holes 602 penetrated through the end surfaces, and the end surfaces of the adjustment blocks 601 opposite to the placement opening 101 are fixed with springs 603, and the springs 603 are slidably sleeved on the corresponding adjustment rods 106.

[0034] The operation process of this embodiment is as follows: when controlling the movement of the positioning bar 6, the positioning bar 6 will drive the adjustment block 601 to slide in the internal position of the adjustment port 105, and the adjustment block 601 will compress the spring 603, so when the positioning bar 6 is released, the spring 603 at this time will directly push the adjustment block 601 to reset and slide, thereby controlling the positioning bar 6 to move back to the upper end surface position of the ear opening 102, and at the same time, the adjustment block 601 is sleeved on the adjustment rod 106 through the adjustment hole 602, so the adjustment rod 106 limits the adjustment block 601, and thereby limits the positioning bar 6. Specific embodiment three

[0035] See also Figure 5 and Figure 6 On the basis of the specific embodiment 1, the slide cylinder 402 is sleeved on the support rod 5 to ensure the stability of the upper mold 4 sliding up and down, thereby achieving precise stamping.

[0036] Specifically, support rods 5 are fixed at the four end corners of the upper end surface of the punching block 1, and the upper end surface of the support rods 5 is fixedly connected to the bottom surface of the top plate 2. Slide cylinders 402 are fixed at the positions of the side surfaces of the upper mold 4 corresponding to the support rods 5, and each slide cylinder 402 is slidably mounted on the support rods 5, and an assembly plate 202 is fixed to the piston end of the punching cylinder 201 passing through the top plate 2, and the assembly plate 202 is connected to the upper mold 4 by bolts.

[0037] The operation process of this embodiment is: the slide 402 is sleeved on the support rod 5, so that the stamping cylinder 201 will control the upper mold 4 to slide up and down. At this time, the support rod 5 limits the slide 402 and resets the upper mold 4, thereby ensuring the sliding stability of the upper mold 4.
