Description

Technical Field

[0001] This utility model relates to the field of punch press technology, specifically a circulating cooling punching mechanism. Background Technology

[0002] Stamping is a common metal forming process in industrial production, widely used in automotive parts, electronic components, and everyday consumer goods. However, in traditional stamping processes, the rapid deformation and friction of metal materials often generate a large amount of heat, leading to increased workpiece temperature, decreased material properties, and even overheating and damage to the die. To address these issues, circulating cooling technology has been introduced into stamping mechanisms to effectively control the heat generated during the stamping process.

[0003] However, common cooling methods often suffer from drawbacks such as uneven cooling, high energy consumption, and complex maintenance. For example, some stamping equipment using external spray or immersion cooling may experience poor cooling uniformity, slow cooling speed, and insufficient heat removal. These problems can affect the performance and production efficiency of the stamping equipment, and may even shorten its service life. Utility Model Content

[0027] Please see Figure 1-5 ,

[0028] A circulating cooling stamping mechanism includes a base plate 1, a stamping groove 2 on the base plate 1, a rear end of the base plate 1 connected to a support plate 3, a top end of the support plate 3 connected to a top plate 4, a hydraulic rod 6 installed on the top end of the top plate 4, and a clamping device 7 installed on the bottom end of the top plate 4. The circulating cooling device 8 is clamped by the clamping device 7.

[0029] The circulating cooling device 8 consists of a cylindrical shell 801, a spiral pipe 802, an inlet pipe 803, an outlet pipe 804, an L-shaped pipe 806, a circulating pump 805, a liquid filling port 809, a second shell 808, and a liquid storage tank 807. The spiral pipe 802 is installed inside the cylindrical shell 801, and the cylindrical shell has an annular hole corresponding to the spiral pipe 802. The inlet pipe 803 and the outlet pipe 804 are respectively installed at the upper and lower ports of the spiral pipe 802. The inlet pipe 803 is installed at the front end of the circulating pump 805, the L-shaped pipe 806 is installed at the rear end of the circulating pump 805, the L-shaped pipe 806 is installed at the top of the liquid circulation tank, and the outlet pipe 804 is installed at the front bottom of the liquid circulation tank. The liquid storage tank 807 is located at the bottom inside the second shell 808, the liquid filling port 809 is located at the rear end of the liquid storage tank 807, and the second shell 808 is installed at the upper rear end of the support plate.

[0030] In this example, the cylindrical shell 801 is provided with through holes that cooperate with the liquid inlet pipe 803 and the liquid outlet pipe 804. The liquid inlet pipe 803 and the liquid outlet pipe 804 pass through the clamping device 7 and the support plate 3. The interior of the shell 808 is divided into upper and lower layers. The lower layer of the shell 808 is a liquid storage tank 807.

[0031] It should be noted that the through holes provided on the cylindrical shell 801 allow coolant to flow into or out of the shell under the action of the inlet pipe 803 and the outlet pipe 804, ensuring effective liquid transfer. The design of the cylindrical shell 801, the inlet pipe 803, the outlet pipe 804 and the shell 808 together constitute a liquid storage and transportation system.

[0032] In this example, the circulation pump 805 and the L-shaped pipe 806 are both installed on the upper layer. One end of the circulation pump 805 is connected to the L-shaped pipe 806 and the other end is connected to the inlet pipe 803. The L-shaped pipe 806 passes through the liquid circulation tank, and the outlet pipe 804 is directly connected to the inside of the liquid storage tank 807. The liquid filling port 809 passes through the housing 808 and the liquid storage tank 807.

[0033] It should be noted that the function of the circulating pump 805 is to drive the liquid to circulate in the pipeline, the function of the inlet pipe 803 is to introduce the coolant in the liquid storage tank 807 into the spiral pipe 802 to cool the stamping shaft 9, and the function of the storage pipe is to introduce the coolant in the spiral pipe 802 into the liquid storage tank 807.

[0034] In this example, the stamping groove 2 is located at the center of the base plate 1, the support plate 3 is installed perpendicularly to the base plate 1, the top plate 4 is installed perpendicularly to the support plate 3, the hydraulic rod 6 at the top of the top plate 4 is wrapped by the housing 5, and the center of the top plate 4 is provided with a stamping shaft 9 that cooperates with the stamping groove 2 of the base plate 1. The stamping shaft 9 passes through the top plate 4, and the top of the stamping shaft 9 is connected to the output end of the hydraulic rod 6.

[0035] It should be noted that the support plate 3 is installed perpendicularly to the base plate 1 and is used to support the top plate 4 and the equipment installed on the top plate 4. The hydraulic rod 6 is the power source of the stamping system and is used to provide stamping force.

[0036] In this example, the clamping device 7 consists of a housing 701, two arc-shaped plates 702, four stepped shafts 703, and four springs 704. The stepped shafts 703 are symmetrically installed at the upper and lower ends of the arc-shaped plates 702. The springs 704 are passed through the stepped shafts 703. The arc-shaped plates 702 are installed opposite each other at the left and right ends inside the housing 701. The housing 701 is installed at the bottom of the top plate 4.

[0037] It should be noted that the shell 701 serves to protect the internal mechanism and provide operating space, while the main function of the arc plate 702 is to contact the surface of the cylindrical shell 801 to provide a uniform clamping force to hold the cylindrical shell 801 and the internal pipes.

[0038] In this example, housing 3 701 is installed at the center of the bottom of top plate 4. Housing 3 701 is provided with through holes that cooperate with liquid inlet pipe 803, liquid outlet pipe 804 and stepped shaft 703. Spring 704 is located between housing 3 701 and arc plate 702. The top and bottom of arc plate 702 are provided with protruding parts for engaging cylindrical housing 801.

[0039] It should be noted that the housing 701 is installed at the center of the bottom of the top plate 4, which can ensure the stability of the clamping device 7 and the uniform distribution of clamping force. The function of the spring 704 is to provide clamping force when clamping the cylindrical housing 801.

[0040] In summary: When using this machine, firstly, expand the arc-shaped plate 702 inside the housing 3 701 to both sides simultaneously, then clamp the cylindrical housing 801. Next, pass the inlet pipe 803 and outlet pipe 804 from the rear through the support plate 3 and housing 3 701 to connect with the cylindrical housing 801. Then, connect the inlet pipe 803 to the circulating pump 805, and simultaneously connect the outlet pipe 804 to the liquid storage tank 807. Finally, install the housing 2 808 on the back of the support plate 3. When the machine is working, the hydraulic rod 6 drives the stamping shaft 9 downwards into the stamping groove 2 to complete the stamping of the material. After the stamping shaft 9 completes the stamping, it moves upwards into the cylindrical housing 801. At this time, the coolant in the spiral pipe 802 inside the cylindrical housing 801 cools the stamping shaft 9. When the coolant is insufficient, it can be added from the liquid inlet 809 at the rear end of the housing 2 808.

[0041] Beneficial effects:

[0042] This circulating cooling stamping mechanism cleverly combines the circulating cooling device with the stamping mechanism, achieving efficient, uniform, and low-dissipation control of the heat generated during the stamping process. It is not only simple in structure and easy to operate, but also has a significant cooling effect, which can significantly improve the efficiency and quality of stamping.
