Description

Technical Field

[0001] This utility model relates to the field of metal surface shot peening technology, and specifically to a surface shot peening strengthening device for metal castings. Background Technology

[0002] In some cases, shot peening equipment is used to peen the surface of metal workpieces in order to shape the surface, increase its surface strength, or increase its wear resistance and corrosion resistance.

[0003] A search revealed existing technology (publication number: CN214088585U), which describes "a shot peening strengthening device for metal surface treatment, including a base, with a worktable fixedly installed on the top of the base. This shot peening strengthening device for metal surface treatment uses a shot peening nozzle to peen the workpiece. Starting the drive motor causes the screw to rotate, pushing the moving sleeve to move left and right, causing the meshing rod to slide left and right. Through meshing, the rotating gear rotates around the rotating shaft, which in turn drives the shot generator to rotate, thereby changing the angle of the shot peening nozzle. By activating the electric push rod, the workpiece box moves left and right, and the sliding block and slide rail work together to stabilize its movement, thus changing the horizontal position of the workpiece. Combined with the angle adjustment of the shot peening nozzle, the workpiece surface can be quickly shot peened and strengthened. The entire process is achieved through mechanical automation, which can greatly save labor and time, and effectively improve processing efficiency."

[0004] Although existing shot peening equipment for metal surface treatment achieves automated operation, it still has some shortcomings: existing shot peening equipment for metal surface treatment does not have the effect of recycling shot. After the shot is screened and dusted, qualified shot can be obtained and then added to the shot peening machine for reuse. Secondly, the metal needs to be turned over multiple times after being placed to achieve shot peening treatment of the entire surface, which is quite troublesome. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, a surface shot peening strengthening device for metal castings is provided to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a shot peening device for surface strengthening of metal castings is provided, comprising: an operation box and a recovery box. The operation box has an observation window on its front side and a partition connected to its lower end. The operation box contains a shot peening assembly, which includes a shot generator with a nozzle at its lower end and a clamping block below the nozzle. A rotary clamping cylinder is connected to the outer end of the clamping block. The recovery box is connected to the lower side of the partition, and a guide hopper is provided between the recovery box and the operation box. A screening box is connected to the lower end of the guide hopper. The screening box has a screening plate at its bottom and a stirring paddle inside. A dust collection hopper is located below the screening plate, and a vacuum cleaner is connected to the outer side of the dust collection hopper.

[0007] Furthermore, the shot peening assembly also includes a mounting bracket, and an adjustment motor is mounted on the outside of the mounting bracket, with the output shaft of the adjustment motor connected to the shot generator.

[0008] Furthermore, the shot generator is rotatably connected to the inside of the mounting frame, and an electric push rod is connected to the top of the mounting frame, with an electric slider and an electric slide rail connected to the upper end of the electric push rod.

[0009] Furthermore, a pair of rotary clamping cylinders are provided, and the rotary clamping cylinders are fixed to the inner walls of both sides of the operating box.

[0010] Furthermore, one end of the screening plate is hinged to the bottom of the screening box, and the other end of the screening plate is connected to a connecting groove opened at the bottom of the screening box, and an insertion hole is opened at the end of the screening plate located in the connecting groove.

[0011] Furthermore, the outer wall of the screening box is provided with a fixed frame, and a rod is slidably inserted into the inside of the fixed frame. A slip ring is fixed on the outside of the rod, and a spring is provided on the outside of the rod. The rod is matched and inserted into the insertion hole.

[0012] Furthermore, the lower end of the dust collection hopper is connected to a support plate, and both ends of the support plate are connected to sliding plates, with the outer ends of the sliding plates slidably connected to a guide groove opened in the inner wall of the recycling bin.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When using, open the observation window, place the metal casting between the two clamping blocks, then start the rotary clamping cylinder to clamp the metal casting, and then start the shot generator so that the metal casting is shot peened under the drive of the electric slide rail and electric slider. At this time, the angle of the spray nozzle is adjusted by adjusting the motor and mounting bracket. At the same time, the metal casting is rotated and moved by the rotary clamping cylinder. Then, the metal casting is flipped and clamped and shot peened again. Thus, the shot peening can be achieved by flipping twice, which improves the convenience and efficiency of operation.

[0015] 2. The dust, broken shot, and whole shot generated during shot blasting are guided downwards to the screening box in the recycling bin using the guide bucket. Then, the stirring paddle turns the dust and broken shot down from the screening plate into the dust collection hopper. The dust is then sucked away by the external vacuum cleaner. Finally, the door of the recycling bin is opened, and the dust collection hopper is pushed back open using the tray and slide plate. The recycling container is then placed under the screening box. At this point, the plug rod is pulled out, causing the screening plate to rotate downwards, allowing the whole shot inside to be poured into the recycling container, achieving the effect of recycling.

A guide hopper 16 is provided between the recovery box 2 and the operation box 1. A screening box 21 is connected to the lower end of the guide hopper 16. A screening plate 22 is provided at the bottom of the screening box 21. A stirring paddle 23 is provided inside the screening box 21. A dust collection hopper 41 is provided at the lower side of the screening plate 22. A vacuum cleaner 4 is connected to the outer side of the dust collection hopper 41.

[0022] In this embodiment, the operation box 1 and the recycling box 2 constitute the main structure of the surface shot peening strengthening device for metal castings involved in this application.

[0023] The working principle of the shot generator 144 and the nozzle 145 is consistent with that of the relevant structures involved in the prior art documents.

[0024] Specifically, the rotary clamping cylinder model 15 is designated as SMC type MKB16-10L, which combines the effects of rotary motion and linear motion, thus facilitating the rotation and flipping of metal castings.

[0025] The guide bucket of the substrate passes through the partition 3, and the lower end of the guide bucket 16 is placed in the upper opening of the screening box 21.

[0026] Specifically, the vacuum cleaner 4 is installed on the outer wall of the recycling bin 2.

[0027] like Figure 2 and Figure 3 In the shot peening assembly 14, there is also a mounting bracket 142, and an adjusting motor 143 is mounted on the outside of the mounting bracket 142. The output shaft of the adjusting motor 143 is connected to the shot generator 144. The shot generator 144 is rotatably connected to the inside of the mounting bracket 142. An electric push rod 141 is connected to the top of the mounting bracket 142. An electric slider 13 and an electric slide rail 12 are connected to the upper end of the electric push rod 141. A pair of rotary clamping cylinders 15 are provided, and the rotary clamping cylinders 15 are fixed to the inner walls of both sides of the operating box 1.

[0028] Specifically, the mounting bracket 142 is designed with an N-shaped structure, and the end of the shot generator 144 away from the output shaft is connected to a rotating shaft, with the outer end of the rotating shaft rotatably connected to the inner wall of the mounting bracket 142.

[0029] As a preferred implementation, the electric slide rail 12 and the electric slider 13 facilitate the linear movement of the nozzle 145, and the adjustment motor 143 facilitates the angle adjustment of the nozzle 145.

[0030] like Figure 2 and Figure 4 In the screening box 21, one end of the screening plate 22 is hinged to the bottom of the screening box 21, and the other end of the screening plate 22 is connected to the connecting groove 211 opened at the bottom of the screening box 21. The end of the screening plate 22 located in the connecting groove 211 is provided with an insertion hole 221. The outer wall of the screening box 21 is provided with a fixing frame 27, and an insertion rod 24 is slidably inserted into the inside of the fixing frame 27. A slip ring 25 is fixed on the outside of the insertion rod 24. A spring 26 is provided on the outside of the insertion rod 24. The insertion rod 24 is matched and inserted into the insertion hole 221. The lower end of the dust collection hopper 41 is connected to a support plate 42, and both ends of the support plate 42 are connected to a sliding plate 43. The outer end of the sliding plate 43 is slidably connected to a guide groove opened in the inner wall of the recycling box 2.

[0031] Specifically, the aperture size of the sieve plate 22 only allows intact pellets to be retained, while broken pellets and dust generated during grinding pass downward through the sieve plate 22.

[0032] It should be noted that the vacuum cleaner 4 is kept on while screening, which creates a certain suction effect under the screening plate 22 and speeds up the screening operation.

[0033] Specifically, the connecting groove 211 is designed as a right-angle notch groove structure, which facilitates the horizontal connection of the screening plate 22, and the upper side wall of the connecting groove 211 achieves the limiting effect on the connecting end of the screening plate 22.

[0034] Specifically, the fixing frame 27 includes two connecting rods of equal length, and the outer ends of the connecting rods are connected to an outer plate.

[0035] Specifically, the slip ring 25 has three through holes inside, and the upper and lower through holes are slidably connected to the two connecting rods of the fixing frame 27, while the middle through hole is through which the insertion rod 24 passes and is fixedly connected.

[0036] In addition, spring 26 is placed between slip ring 25 and outer plate of fixing bracket 27, insert rod 24 slides through outer plate of fixing bracket 27, and a protrusion is connected to the outer end of insert rod 24.

[0037] It should be noted that when the dust collection hopper 41 is in operation, there is a movable space behind it.

[0038] In operation, open the observation window, place the metal casting between the two clamping blocks, and then activate the rotary clamping cylinder to clamp the metal casting. Next, activate the shot generator, which, driven by the electric slide rail and electric slider, performs shot peening on the metal casting. Adjust the angle of the nozzle by adjusting the motor and mounting bracket, and simultaneously rotate and move the metal casting using the rotary clamping cylinder. Then, change the side of the metal casting and perform the clamping and shot peening operation again. Use the guide bucket to guide the dust, broken shot, and intact shot generated during shot peening downwards into the screening box in the recovery box. Then, use the stirring paddle to tumble the dust and broken shot from the screening plate into the dust collection hopper, which is then sucked away by the external vacuum cleaner. Finally, open the door of the recovery box, push the dust collection hopper back open using the pallet and slide plate, and place the recovery container under the screening box. Pull out the insert rod to rotate the screening plate downwards, allowing the intact shot inside to be poured into the recovery container.

[0039] The surface shot peening device for metal castings of this invention can effectively solve the problems mentioned in the background technology. It achieves the effect of easy recycling of shot material on the basis of existing surface shot peening devices for metal castings, and further improves the convenience and efficiency of shot peening treatment of metal castings.
