Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die for a cassette furnace bottom plate. Background Technology

[0002] A portable butane gas stove, also known as a cassette stove, is a non-stationary cooking appliance that primarily uses butane gas as its fuel, although liquefied petroleum gas (LPG) and other gases can also be used. This type of stove heats the food directly through a flame and is widely used in various fields such as home and outdoor leisure, and hotel supplies. The cassette stove base plate stamping die is a special mold used to produce the base plate of the cassette stove.

[0003] Currently, for small factories, purchasing large-scale specialized stamping equipment is too expensive when stamping the bottom plate of a cassette furnace. However, when using ordinary stamping equipment, the stamping die requires manual placement and alignment of the stamping blank. Manual alignment cannot accurately and quickly align the blank, which not only affects processing efficiency but may also affect the quality of the finished product due to inaccurate alignment. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a stamping die for a card-type furnace bottom plate. This is to solve the problem that in the prior art, some small factories purchase large-scale special stamping equipment, which is too expensive. When using ordinary stamping equipment, the stamping die requires manual placement and alignment of the stamping blank in the die. However, manual alignment cannot accurately and quickly align the blank, which not only affects the processing efficiency but may also affect the quality of the finished product due to inaccurate alignment.

Detailed Implementation

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, a stamping die for a card-type furnace bottom plate according to an embodiment of the present invention. Example 1

[0025] For easier understanding, please refer to Figures 1 to 4An embodiment of a stamping die for a card-type furnace bottom plate provided by this utility model includes a base 1, a frame 2 fixedly installed at the top of one end of the base 1, a hydraulic cylinder 3 fixedly installed at the top of the frame 2, an upper die base 4 fixedly installed at the output end of the hydraulic cylinder 3, a lower die base 5 fixedly installed at the top of the base 1, an upper die 6 fixedly installed at the bottom of the upper die base 4, a lower die 7 fixedly installed on the inner side of the lower die base 5, and a positioning component provided between the upper die base 4 and the lower die base 5;

[0026] It should be noted that the upper mold base 4 is pressed down by the hydraulic cylinder 3, so that the upper mold 6 and the lower mold 7 cooperate to perform the stamping work.

[0027] The positioning assembly includes a pressing structure 800, a first hydraulic cylinder 801, a first plunger 802, a first round rod 803, a pressure block 804, a first return spring 805, a second hydraulic cylinder 806, a second plunger 807, a second round rod 808, a push block 809, a second return spring 810, and an oil pipe 811. The pressing structure 800 is located at both ends of the upper mold base 4. The first hydraulic cylinder 801 is fixedly installed at both ends of the lower mold base 5. The first plunger 802 is slidably connected to the inner side of the first hydraulic cylinder 801. One end of the first round rod 803 is fixedly installed on one side of the first plunger 802. The pressure block 804 is fixedly connected to one end of the first round rod 803. The first return spring 805 is sleeved on the outer side of the first round rod 803. The second hydraulic cylinder 806 is fixedly installed at the four corners of the lower mold base 5. The second plunger 807 is slidably connected inside the second hydraulic cylinder 806. One end of the second round rod 808 is fixedly installed on one side of the second plunger 807. The push block 809 is fixedly installed on one end of the second round rod 808. The second return spring 810 is sleeved on the outer wall of the second round rod 808. The oil pipe 811 is fixedly installed between the first hydraulic cylinder 801 and the second hydraulic cylinder 806. One end of the first return spring 805 abuts against one end of the outer side of the first hydraulic cylinder 801, and the other end of the first return spring 805 abuts against one end of the pressure block 804. The push block 809 is located at the four corners of the lower mold 7. The inner angle of the push block 809 is 90 degrees. One end of the second return spring 810 abuts against one end of the inner side of the second hydraulic cylinder 806, and the other end of the second return spring 810 abuts against one side of the second plunger 807.

[0028] It should be noted that by setting up the first hydraulic cylinder 801 and the second hydraulic cylinder 806, when stamping is performed, the upper die base 4 drives the lower pressing structure 800 and the lower pressing block 804, so that the first round rod 803 drives the first plunger 802 to push the hydraulic oil inside the first hydraulic cylinder 801. Then the hydraulic oil pushes the second plunger 807 through the oil pipe 811, so that the second round rod 808 drives the push block 809. The four push blocks 809 advance simultaneously to position the blank. After stamping, the first return spring 805 and the second return spring 810 reset the first plunger 802 and the second plunger 807. Automatic positioning is performed during use, which improves positioning accuracy and positioning efficiency, and improves processing efficiency. In specific implementation, the second hydraulic cylinder 806 can be installed on the four sides of the lower die base 5 to achieve the same positioning effect. Example 2

[0029] In some embodiments, such as Figure 2 As shown, the pressing structure 800 includes a support arm 8001, an adjusting screw 8002, a pressing head 8003, and a rotating handle 8004. The support arm 8001 is fixedly installed at one end of the upper mold base 4. The adjusting screw 8002 is rotatably connected to one end of the support arm 8001. The pressing head 8003 is fixedly installed at the bottom of the adjusting screw 8002. The rotating handle 8004 is fixedly installed at the top of the adjusting screw 8002. The adjusting screw 8002 and the support arm 8001 are connected by a thread. The pressing head 8003 is located at the top of the pressing block 804.

[0030] It should be noted that an adjusting screw 8002 is used to adjust the position of the pressing head 8003. By rotating the adjusting screw 8002 with the handle 8004, the extension of the pressing head 8003 is adjusted, thereby adjusting the pressing depth of the pressing block 804. This allows for adjustment of the extension of the push block 809, facilitating the positioning of different sized batches. In specific implementation, the second hydraulic cylinder 806 is installed on the four sides of the lower mold base 5.

[0031] Working principle: In use, firstly, the position of the lower pressure head 8003 is adjusted by the adjusting screw 8002. The extension of the lower pressure head 8003 is adjusted by rotating the adjusting screw 8002 through the rotating handle 8004, thereby adjusting the pressing depth of the pressure block 804. This allows for adjustment of the extension of the push block 809, enabling positioning according to the size of the blank. Then, during stamping, the upper die holder 4 drives the lower pressing structure 800, pressing down the pressure block 804. This causes the first round rod 803 to drive the first plunger 802, pushing the hydraulic oil inside the first hydraulic cylinder 801. The hydraulic oil then pushes the second plunger 807 through the oil pipe 811, causing the second round rod 808 to drive the push block 809. All four push blocks 809 advance simultaneously, positioning the blank. After stamping, the first return spring 805 and the second return spring 810 reset the first plunger 802 and the second plunger 807. Automatic positioning is performed during use, improving positioning accuracy and efficiency, and increasing processing efficiency.
