Description

Technical Field

[0001] This utility model relates to the technical field of stamping machine tools, and specifically to a stamping machine tool with a heat dissipation structure. Background Technology

[0002] A stamping machine, also known as a punch press or press, is an important metal processing equipment. It is a general term for equipment that applies pressure to materials using a die, causing plastic deformation to obtain the desired shape and precision. Stamping machines are widely used in electronics, communications, computers, home appliances, furniture, transportation vehicles, and hardware parts, among other fields. During operation, stamping machines generate a large amount of heat due to friction between the motor, transmission components, die, and material. If this heat cannot be dissipated in time, the internal temperature of the machine will rise, affecting its precision and stability. Therefore, heat dissipation measures must be taken for the main heat-generating parts of the stamping machine.

[0003] Existing stamping machine tools typically employ fixed heat dissipation structures. For example, a multi-station stamping device for producing metal parts, disclosed in application number CN201921941977.8, uses a single heat dissipation hole for cooling, and the heat dissipation structure is usually fixed in place. Fixed heat dissipation structures often cannot be flexibly adjusted according to the actual operating temperature and cooling requirements of the machine tool. Fixed heat dissipation structures usually occupy a certain amount of space, which limits the overall layout of the machine tool. When it is necessary to optimize the machine tool layout or add other functional components, fixed heat dissipation structures may become obstacles. In addition, in processing environments with limited space, fixed heat dissipation structures may further exacerbate the space shortage problem. Fixed heat dissipation structures may also more easily accumulate dust and dirt, affecting the heat dissipation effect and requiring more frequent cleaning and maintenance, thus affecting the heat dissipation performance.

[0004] Therefore, it is necessary to invent a stamping machine tool with a heat dissipation structure to solve the above problems. Utility Model Content

During disassembly, the entire assembly is pulled out from bottom to top via the detachable strip 302. A punch head 4 is located below the cylinder platform 3, and a punch seat 5 is located directly below the punch head 4. The punch seat 5 is located in the middle of the front side of the surface of the workbench 1. A storage groove 6 is provided in the lower middle of the middle of the frame 2. A fixed seat 7 is installed in the storage groove 6. A moving groove 701 is provided in the middle of the surface of the fixed seat 7. A reciprocating screw 702 is installed in the middle of the moving groove 701. Rotating shafts 703 are installed at the connection points between the two ends of the reciprocating screw 702 and the inner walls of the moving groove 701. One end of the reciprocating screw 702 is connected to the output end of an external motor for rotation.

[0026] A cooling fan 8 is installed above the fixed base 7, and a movable base 9 is installed in the middle of the fixed base 7. The installation position of the fixed base 7 is lower than the surface position of the stamping base 5. Two cooling fans 8 are provided on the upper sides of the fixed base 7. The cooling fans 8 are adjustable. An upper rotating sleeve 801 is installed on one side of the top of the cooling fan 8, and a lower rotating sleeve 802 is installed on the same side of the bottom of the cooling fan 8. A sliding rotating column 803 is installed above the middle of the upper rotating sleeve 801. The top sides of the storage groove 6 in the middle of the frame 2 are provided with sliding grooves 804 that match the size of the sliding rotating column 803. The bottom of the movable sleeve 802 is equipped with a fixed rotating column 805. The sliding rotating column 803 can move linearly in the sliding groove 804. The bottom end of the fixed rotating column 805 is fixed on the top surface of the movable seat 9. The cooling fan 8 can rotate left and right on the sliding rotating column 803 and the fixed rotating column 805 respectively through the upper rotating sleeve 801 and the lower rotating sleeve 802. The movable seat 9 moves back and forth above the fixed seat 7, and drives the cooling fan 8 to move in position. The outer wall of the lower rotating sleeve 802 is equipped with a positioning pin. The cooling fan 8 is located on the surface of the movable seat 9 and is movable.

[0027] The heat sink 301 and cooling fan 8 mentioned above are existing technology products, and their specific structures and functions will not be described in detail here.

[0028] The working principle of this practical application is as follows:

[0029] Refer to the instruction manual appendix Figure 1-5This type of stamping machine tool with a heat dissipation structure first adopts a dual heat dissipation fan 8 plus a movable design. The heat dissipation area is dynamically covered by the moving seat 9 and the reciprocating screw 702 to improve heat dissipation efficiency. The cylinder platform 3 integrates a detachable heat sink 301, which can be quickly maintained by the figure-eight detachable strip 302 to adapt to different heat dissipation needs. The heat dissipation fan 8 can swing left and right through the sliding column 803 plus the fixed column 805 structure. After the lower rotating sleeve 802 is rotated to a fixed position, there is a positioning pin through the surface of the fixed column 805, which is used to fix the position of the heat dissipation fan 8 after swing adjustment. When it is necessary to move the position of the heat dissipation fan 8, the positioning pin can be pulled out. Combined with the forward and backward movement of the moving seat 9, a three-dimensional heat dissipation path is formed to accurately cool the stamping head 4 and the stamping seat 5. The fixed seat 7 is lower than the stamping seat 5 to avoid interfering with the stamping operation. At the same time, the heat dissipation components can be hidden by the storage slot 6 when the heat dissipation is not in use, saving space.

[0030] An external motor drives the reciprocating screw 702 to rotate and then the moving seat 9 moves back and forth along the moving groove 701, which in turn drives the cooling fan 8 to move synchronously. The cooling fan 8 swings left and right around the sliding rotating column 803 and the fixed rotating column 805 through the upper rotating sleeve 801 and the lower rotating sleeve 802, expanding the airflow coverage. The heat sink 301 is fixed to the cylinder platform 3 by the detachable strip 302. Heat is conducted to the outside through the heat sink 301. When cleaning is required, the detachable strip 302 can be pulled out directly to disassemble the whole device. Regular cleaning can effectively improve the heat dissipation effect and efficiency of the heat sink 301 for the device. During the stamping operation, the cooling fan 8 automatically moves to the vicinity of the stamping head 4 and swings to blow air to cool the high temperature area. When in standby mode, the cooling fan retreats into the storage groove 6 to reduce dust accumulation.

[0031] When using this device, turn on the external motor, and the cooling fan 8 moves back and forth along the moving slot 701. At the same time, manually or automatically adjust the swing angle. When cleaning and maintaining the heat sink 301, pull out the removable strip 302, and then after removing the heat sink 301, clean or replace it and reinsert it into the removable slot 303. After stopping the machine, move the moving seat 9 to the end of the storage slot 6 and remove the fixed rotating column 805 for maintenance. Dynamic heat dissipation covers the key stamping heat-generating parts, which can effectively improve efficiency compared with the fixed heat dissipation structure. This stamping machine with heat dissipation structure can effectively reduce the internal temperature of the machine tool, improve the stability and service life of the machine tool. At the same time, the adjustable and maintainable design of the heat dissipation system makes the heat dissipation performance of the machine tool more flexible and reliable.
