Description

Technical Field

[0001] This utility model belongs to the field of metal material processing technology, and specifically relates to an automatic shot peening equipment for castings. Background Technology

[0002] Internal cavity shot peening is commonly used for cleaning the internal cavities of castings. A pressurized steel shot is propelled from a shot blasting gun to clean the casting's internal cavities, improving cleanliness. Traditional manual shot peening machines require a manual operator to hold the shot blasting gun with one hand and adjust the casting angle with the other, aligning the nozzle with the cavity opening, starting the machine, and maintaining the nozzle position until peening is complete. For castings with multiple cavities, this process needs to be repeated multiple times, resulting in low efficiency. Furthermore, the high pressure of the shot blasting gun and prolonged hand operation can lead to fatigue, insufficient effective peening time, and ultimately, substandard casting quality. Utility Model Content

[0003] This invention addresses the problems of low shot peening efficiency and insufficient effective shot peening time in existing multi-chamber castings by providing an automatic shot peening device for castings.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

The air inlet of each T-shaped discharge pipe is connected to the secondary air collection chamber pipe, and the shot outlet of each T-shaped discharge pipe is connected to the shot peening gun pipe.

[0006] Furthermore, a first solenoid valve is fixedly installed on the side of the shot peening collection chamber and communicates with its interior. The first solenoid valve has an internal air pressure balance port. The first solenoid valve is connected in sequence to a second solenoid valve and a secondary gas collection bag pipeline. The first solenoid valve can control the gas in the secondary gas collection bag to form a positive pressure space inside the shot peening collection chamber.

[0007] Furthermore, a support plate is integrally fixedly installed on the bottom surface of the shot peening collection chamber, and a cylinder is fixedly installed above the support plate. A sealing component is detachably connected to the cylinder's drive shaft.

[0008] Furthermore, the other outlet of the first solenoid valve is pneumatically connected to the cylinder.

[0009] Furthermore, a spray gun fixing shaft is fixedly connected to both sides inside the shot peening chamber, and a sleeve shaft is sleeved on the spray gun fixing shaft; the sleeve shaft is fixedly connected to a universal ball joint fixing clamp; the sleeve shaft is pressure-bearing against the spray gun fixing shaft through the thread of a positioning screw; the universal ball joint fixing clamp is fixedly connected to the spray gun.

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] Example 1, see Figure 1 ,

[0022] An automatic shot peening device for castings includes a main body 101, a secondary air collection chamber 102, a shot peening chamber 103, a shot peening collection bin 104, and a shot peening collection hopper 105. The secondary air collection chamber 102 is fixedly installed at one end of the lower upper layer of the main body 101, and the shot peening collection bin 104 is fixedly installed at the other end. The shot peening chamber 103 is installed on the upper layer of the main body 101, and a shot peening gun 106 is installed inside the shot peening chamber 103. A screen plate 107 is installed at the bottom of the shot peening chamber 103. A shot peening collection hopper 105 is fixedly installed at the bottom of the sieve plate 107 to cooperate with it; the shot peening collection hopper 105 is flange-connected to the shot peening collection chamber 104; at least three three-way discharge pipes 108 are integrally fixedly connected to the bottom of the shot peening collection chamber 104, and the middle port of the three-way discharge pipe 108 is connected to the inside of the shot peening collection chamber 104; the air inlet 109 of the three-way discharge pipe is connected to the secondary air collection manifold 102, and the shot outlet 110 of the three-way discharge pipe is connected to the spray gun 106.

[0023] Furthermore, a first solenoid valve 111 is fixedly installed on the side of the shot peening collection chamber 104, communicating with its interior. The first solenoid valve 111 has an internal air pressure balance port 112. The first solenoid valve 111 is sequentially connected to a second solenoid valve 113 and a secondary gas collection manifold 102 pipe. The first solenoid valve 111 can control the gas in the secondary gas collection manifold 102 to form a positive pressure space inside the shot peening collection chamber 104. This positive pressure applies downward pressure to the shot peening material flowing into the three-way discharge pipe 108 within the shot peening collection chamber 104, causing the shot peening material to continue to be subjected to gas pressure from the secondary gas collection manifold 102, thus allowing the shot peening material to be ejected from the spray gun through the pipe and complete the shot peening of the casting within the shot peening chamber 103.

[0024] Furthermore, a support plate 114 is integrally fixedly installed on the bottom surface of the shot peening collection chamber 104, and a cylinder 115 is fixedly installed above the support plate 114. A sealing component 116 is detachably connected to the transmission shaft of the cylinder 115.

[0025] Furthermore, another outlet of the first solenoid valve 111 is pneumatically connected to the cylinder 115. By adopting a pneumatic connection with the first solenoid valve 111, the cylinder 115 can receive a gas source from the secondary gas collection bag 102 as power to further control the opening and closing of the sealing element 116.

[0026] The use of the sealing and sealing component 116 further enhances the pressure of the positive pressure space in the shot peening collection chamber 104 when the equipment is working, so that the shot can flow out of the shot peening collection chamber 104 more efficiently to participate in the shot peening of the casting.

[0027] Furthermore, a spray gun fixing shaft 117 is fixedly connected to both sides inside the shot peening chamber 103, and a sleeve shaft 118 is sleeved on the spray gun fixing shaft 117; the sleeve shaft 118 is fixedly connected to a universal ball head fixing clamp 119; the sleeve shaft 118 is pressure-bearing against the spray gun fixing shaft 117 through the thread of the positioning screw 120, and the universal ball head fixing clamp 119 is fixedly connected to the spray gun 106.

[0028] Furthermore, a third solenoid valve 121 is connected between the air inlet 109 of the three-way discharge pipe and the secondary air collection manifold 102; an electrical control terminal 122 is fixedly installed on the front of the main body 1; the first solenoid valve 111, the second solenoid valve 113, and the third solenoid valve 121 are electrically connected to the electrical control terminal 122. This method allows for more precise control of the shot peening process.

[0029] Furthermore, the shot peening chamber 103 is provided with an isolation door 123 on its front side, which slides up and down with the main body of the equipment; an isolation door limit switch 124 is fixed on the side of the isolation door 123, and the isolation door limit switch 124 is electrically connected to the electronic control terminal 122. The isolation door limit switch 124 is provided to ensure safety and is used to detect the travel and position of the isolation door 123. When the isolation door 123 is open, if the equipment is working, the electronic control terminal 122 will output a command to stop the equipment. If the equipment is not working and the isolation door 123 is still open, the electronic control terminal cannot be manually operated to start the equipment. Only when the isolation door 123 is closed can the electronic control terminal 122 be operated to start the equipment.

[0030] In use, the casting to be treated is placed in the shot peening chamber 103. By adjusting the positioning screw 120 and the universal ball joint fixing clamp 119, the nozzle of the shot peening gun 106 is aligned with the casting cavity opening. Then, the isolation door 123 is closed. The electronic control terminal 122 is operated to issue a start command. At this time, the second solenoid valve 113 opens, and the first solenoid valve 111 first opens the air outlet connecting the secondary air collection manifold 102 and the cylinder 115, providing air power to the cylinder 115, causing the sealing and sealing component 116 to move upward, thereby sealing and sealing the flange connection between the shot peening collection hopper 105 and the shot peening collection chamber 104. Then, the first solenoid valve 111 opens the outlet connecting the inside of the shot peening collection chamber 104 with the secondary gas collection chamber 102, providing positive pressure to the inside of the shot peening collection chamber 104, allowing the shot to flow more efficiently downwards into the three-way discharge pipe 108; the third solenoid valve 121 opens, connecting the secondary gas collection chamber 102 with the air inlet 109 of the three-way discharge pipe, and the secondary gas collection chamber 102 provides a gas pressure source to the air inlet 109 of the three-way discharge pipe; the shot thus enters the pipe from the shot outlet 110, and is then sprayed out from the spray gun 106 to treat the inner cavity of the casting. At this time, the shot that has been sprayed out from the spray gun 106 falls into the shot peening collection hopper 105 from the sieve plate 107 set at the bottom of the shot peening chamber 104.

[0031] After the shot peening operation is completed, the first solenoid valve 111 connects the air pressure balance port 112 inside the chamber and the shot peening collection chamber 104 to balance the air pressure inside and outside the shot peening collection chamber 104. Then, the cylinder 115 drives the sealing and sealing component 116 to move downward, and the flange connection between the shot peening collection hopper 105 and the shot peening collection chamber 104 is opened. At this time, the shot in the shot peening collection hopper 105 flows into the shot peening collection chamber 104 under the action of gravity, waiting for the next use.

[0032] Compared with existing technologies, this invention improves the degree of automation, allowing multiple spray guns to simultaneously perform shot peening operations on the inner cavity of castings, ensuring sufficient effective shot peening time, improving work efficiency, reducing labor intensity, guaranteeing the quality of shot peening of castings, and ensuring safety and reliability.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
