Description

Technical Field

[0001] This utility model relates to the technical field of steel shot forming equipment, specifically a steel shot pressing and forming machine. Background Technology

[0002] Steel shot is a spherical particle made from special materials through special heat treatment. It is a commonly used material for treating metal workpieces. Steel shot has a dense structure and uniform particle size. Treating the surface of metal workpieces with steel shot can increase the surface pressure of the metal workpiece, which can effectively improve the fatigue resistance of the workpiece. Steel shot is widely used.

[0003] For example, a steel shot pressing and forming machine disclosed in patent publication number CN222873332U includes a worktable, multiple support legs, a base plate, an upper mold, and a lower mold. Support legs are fixedly installed at the four corners of the bottom of the worktable, and a base plate is fixedly installed at the bottom of the support legs. Supports are fixedly installed at the left and right ends of the rear top of the worktable, and a top plate is fixedly installed at the top of the support. Fixed columns are fixedly installed at the four corners of the bottom of the top plate, and an upper mold is fixedly installed at the bottom of the fixed columns. Multiple semi-circular grooves are opened in the lower part of the upper mold, and a channel communicating with the semi-circular grooves is opened in the upper part of the upper mold. An injection pipe is fixedly installed in the middle of the top plate, and the output end of the injection pipe is connected to the channel. The bottom of the lower mold is installed on the top of the worktable through a moving component, and a lower semi-circular groove is opened at the position corresponding to the semi-circular grooves on the top of the lower mold.

[0004] However, although such equipment can compress and shape steel shot, the cooling chamber is used to cool the steel shot. The cooling efficiency of the cooling chamber will affect the forming rate of the steel shot. After the cooling chamber has been used for a long time, scale will accumulate on the inner wall of the cooling chamber, thereby reducing the cooling rate of the steel shot and making it easy for defective steel shot to appear.

[0005] Therefore, we propose a steel shot pressing and forming machine. Utility Model Content

[0006] One of the technical problems this application aims to solve is to reduce the scaling rate of the cooling chamber.

[0007] To solve the above-mentioned technical problems, this application provides a steel shot pressing and forming machine, including an upper mold and a lower mold. The upper mold is slidably connected to the lower mold by a positioning rod. Semi-circular forming grooves are distributed in both the upper mold and the lower mold. A cooling cavity is provided in the lower mold. The cooling cavity is characterized in that multiple diversion pipes can be detached from both ends, and a sludge outlet is provided at one end of each cooling cavity. The confluence of the multiple diversion pipes at one end of the cooling cavity is connected to a flushing assembly for reverse flushing of the cooling cavity.

[0008] In some embodiments, pipe flanges are fixedly installed inside both ends of the cooling cavity, and the pipe flanges have internal threads.

[0009] In some embodiments, one end of the diverter tube is provided with an external thread that mates with the internal thread.

[0010] In some embodiments, one end of one of the multiple sets of diversion pipes at one end of the lower mold is connected to a common water inlet threaded pipe, one end of the water inlet threaded pipe is externally threaded to a threaded main pipe, and a screen plate is snapped into the threaded main pipe.

[0011] In some embodiments, the bottom inner wall of the cooling chamber is inclined, and the drain outlet is located in the bottom recess of the cooling chamber.

[0012] In some embodiments, the rinsing assembly includes a high-pressure pump located below the lower mold. One end of a multi-component flow pipe at the other end of the lower mold is connected to a main water outlet pipe. The outlet end of the high-pressure pump is fixedly connected to one end of the main water outlet pipe. A three-position four-way solenoid valve is fixedly installed on the main water outlet pipe, and a water outlet pipe is fixedly connected to one side of the three-position four-way solenoid valve.

[0013] In some embodiments, a sewage discharge solenoid valve is provided at the end of the sewage outlet, and a sewage discharge pipe is fixedly connected to the lower end of the sewage outlet.

[0014] This utility model has at least the following beneficial effects: the device can perform reverse flushing from the bottom recess of the cooling chamber through the flushing component, and the inclined design of the cooling chamber makes it easier to drain the sewage from the cooling chamber, which greatly increases the cooling efficiency of the cooling chamber. The detachable screen plate at the water inlet end of the cooling chamber further reduces the scaling rate of the inner wall of the cooling chamber, avoids defects in steel shot forming (such as cracks and dimensional deviations) caused by poor cooling, and extends the service life of the cooling chamber.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figure 1-6 A steel shot pressing and forming machine includes an upper mold 1 and a lower mold 2. The upper mold 1 is slidably engaged with the lower mold 2 by a positioning rod 3. Semi-circular forming grooves 4 are distributed in both the upper mold 1 and the lower mold 2. A cooling cavity 5 is provided in the lower mold 2. Multiple flow pipes 6 can be detached from both ends of the cooling cavity 5, and a sludge outlet 7 is provided at one end of the cooling cavity 5. A flushing component 8 is connected to the confluence end of the multiple flow pipes 6 at one end of the cooling cavity 5 for reverse flushing of the cooling cavity 5.

[0019] Example 2: In order to facilitate the disassembly of the splitter pipe 6, thereby facilitating the overall cleaning of the cooling chamber 5; Both ends of the cooling chamber 5 are fixedly installed with pipe flanges 9. The pipe flanges 9 have internal threads 10. One end of the multi-component flow pipes 6 at one end of the lower mold 2 is connected to a common water inlet threaded pipe 11. One end of the water inlet threaded pipe 11 is externally threaded to a threaded main pipe 12. A screen plate 13 is snapped into the threaded main pipe 12. It should be noted that the pipe flanges 9 are fixedly installed at the end of the cooling chamber 5 by screws, and a sealing gasket (not shown in the figure) is provided at the contact position between the outer wall of the pipe flange 9 and the inner wall of the cooling chamber 5 to prevent water leakage from the cooling chamber 5. The water inlet threaded pipe 11 has external threads at one end. The threaded main pipe 12 is fitted onto the inlet threaded pipe 11. Both ends of the screen plate 13 have protrusions, and the threaded main pipe 12 has grooves that mate with these protrusions to secure the screen plate 13. When the threaded main pipe 12 is fitted into the inlet threaded pipe 11, the screen plate 13 is secured. One end of the threaded main pipe 12 can be connected to an external water injection device, which is controlled by an external PLC. Since the external water injection device and PLC are common, existing equipment on the market, and their principles and structures are based on existing technology, their structure is not described in this paper and is not shown in the figure.

[0020] Example 3: In order to facilitate high-pressure flushing of cooling chamber 5; The bottom inner wall of the cooling chamber 5 is inclined, and the drain outlet 7 is located in the bottom recess of the cooling chamber 5. The flushing assembly 8 includes a high-pressure pump, which is located below the lower mold 2. One end of the multi-component flow pipe 6 at the other end of the lower mold 2 is connected to the main water outlet pipe 14. The outlet end of the high-pressure water pump is fixedly connected to one end of the main water outlet pipe 14. The flushing assembly 8 includes a three-position four-way solenoid valve 801, which is installed on the main water outlet pipe 14. A water outlet pipe 802 is fixedly connected to one side of the three-position four-way solenoid valve 801. A drain solenoid valve 15 is installed at the end of the drain outlet 7, and a drain pipe 16 is fixedly connected to the lower end of the drain outlet 7. It should be noted that the operator controls the high-pressure water pump and the three-position four-way solenoid valve 801 connected to it through a PLC. During normal drainage, the operator can switch the drain pipe through the three-position four-way solenoid valve 801, so that the water flowing from the inlet end of the cooling chamber 5 to the outlet end of the cooling chamber 5, and then discharged from the water outlet pipe 802. When the cooling chamber 5 is being flushed, the PLC controls the three-position four-way solenoid valve 801 to switch the pipeline, so that the high-pressure water pump can reverse the flow of high-pressure water from the main outlet pipe 14 into the cooling chamber 5. At this time, the reverse flushing can accelerate the shedding rate of scale inside the cooling chamber 5. The PLC controls the opening of the drain solenoid valve 15 set in the drain outlet 7 to facilitate the discharge of sewage in the cooling chamber 5, thereby completing the cleaning of the drain pipe 16. It should be noted that the selection of high-pressure water pump and three-position four-way solenoid valve 801 depends on the size of the device, so the model of this device is not limited. Although the lower mold 2 of this device is limited to the upper mold 1 by the positioning rod 3, this device needs to connect a drive device to the top of the upper mold 1 to drive the upper mold 1 to move closer to the lower mold 2 to complete the pressing and forming of steel shot. It also needs to connect an injection port inside the upper mold 1. Since the drive device and the injection port are common existing technologies on the market, the structure of this device is not described.
