[0002] Shot blasting machine refers to casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. The shot blasting machine can simultaneously remove sand, core and clean the castings. The shot blasting machine can also be used to remove burrs, diaphragms and rust.

[0027] The following will be combined with the accompanying drawings in the present invention Figure 1-Figure 8 , clearly and completely describe the specific technical solutions of the present invention; See also Figure 1-Figure 8 , Figure 1 It is a schematic diagram of the overall structure of an embodiment of the present invention; Figure 2 It is a schematic diagram of the internal structure of the casing of the present invention; Figure 3 It is a schematic diagram of the wheel frame structure of the present invention; Figure 4 For the present invention Figure 3 A schematic diagram of the structure at A; Figure 5 It is a schematic diagram of the feeding pipe structure of the present invention; Figure 6It is a schematic diagram of the hanging needle structure of the present invention; Figure 7 For the present invention Figure 6 A schematic diagram of the structure at B; Figure 8 It is a schematic diagram of the side panel structure of the present invention.

[0028] The present embodiment provides a safe spring reinforced shot blasting machine, comprising a base frame, a housing with double discs fixed on the base frame, a shot blasting device driven by a driving motor to blast shots into the housing in the circumference of the housing, a spike wheel frame driven by another driving motor in the housing, a spring feed pipe and a discharge pipe are symmetrically arranged on both sides of the housing obliquely toward the center, the feed pipe and the discharge pipe are both arranged to align with the needle-shaped structure of the circumference of the wheel frame, the two housings are arranged at high and low positions, the discharge pipe of the high housing is connected to the feed pipe of the low housing, and the bottoms of the two housings are provided with discharge pipes for projectiles; The two connected wheel conveying structures are used to drive the spring to change the contact angle with the shot blasting. At the same time, the whole spring can be inverted, thereby realizing multi-angle shot blasting processing and improving uniformity. At the same time, the spring shot blasting can be carried out on an assembly line without stopping the machine to replace the workpiece, which greatly improves the processing efficiency.

[0029] Among them, the shot blasting machine is arranged between the feed pipe and the discharge pipe in the circumferential direction of the casing along the rotation direction of the wheel frame, so as to achieve the maximum change of the contact angle with the projectile while being as close to the projectile throwing position as possible, thereby improving the uniformity of shot blasting.

[0030] Among them, the upper half of the part where the feed pipe and the discharge pipe extend into the casing is open, and the center of the lower half is axially provided with a needle groove for the wheel frame to pass through, so that the spring can be inserted and slipped during the rotation of the wheel frame.

[0031] The casing includes a wheel and a guide plate. The wheel is a hollow disc structure. The feed pipe and the discharge pipe are connected to the wheel. The wheel frame is rotatably connected to the center of the wheel and is spaced apart from the inner wall of the wheel to leave space for the thrown projectiles to disperse and avoid the shot blasting position being too narrow.

[0032] Specifically, the discharge pipe is provided with a sloped guide plate connected to the horizontal quarter point position of the wheel disc, and the two ends of the guide plate respectively correspond to the inner diameter of the wheel disc and the outer diameter range of the wheel frame, so as to limit the spring on the lower half of the wheel disc that is in the sliding range affected by gravity, so as to prevent it from sliding prematurely or getting stuck and deformed.

[0033] Furthermore, the casing also includes a side plate, which is a fan-shaped structural plate ranging from the feed port to the guide plate, and is arranged in a trumpet-shaped structure with a larger upper part and a smaller lower part along the radial direction of the casing, so as to limit the movement of the projectile and reflect the projectile to achieve lateral impact, thereby improving the shot blasting effect.

[0034] The wheel frame includes a driving frame and a hanging needle. The driving frame is a disc structure rotatably arranged in the center of the housing and is connected to the driving motor by transmission. The driving frame is vertically arranged with a hanging needle rotating along its own circumference. Through the setting of the driving frame, that is, the hanging needle rotating on the driving frame, after the spring is nested on the hanging needle, it rotates along the circumference of the driving frame under the drive of the driving frame, so as to change the impact angle of the spring by the projectile in two dimensions and achieve a uniform shot blasting effect.

[0035] Specifically, the hanging needle includes a driving shaft and a driving platform. The driving shaft is rotatably connected to the original driving frame. The bottom end of the part protruding outside the driving frame is provided with an enlarged driving platform. The driving platform is a frustum structure. The bottom of the spring is guided and limited by the conical driving platform to avoid excessive shaking during the processing process.

[0036] Furthermore, a protruding circumferential step structure is provided on the top conical surface of the driving platform; The stepped surface structure fits the stepped shape of the spring end position to achieve a better circumferential transmission effect, ensuring that the spring moves circumferentially with the wheel frame and also rotates circumferentially with the hanging needle, achieving uniform processing at multiple angles.

[0037] Furthermore, a portion of the circumference of the drive shaft that extends into the drive frame has a gear ring structure, which meshes with the drive gear ring protruding from the inner wall of the casing for transmission. The drive shaft moves relative to the gear ring as the drive frame rotates, thereby achieving synchronous driving of all hanging needles.

[0038] When implementing the technical solution recorded in this embodiment, after the shot blasting machine is started, the projectiles are transported into the shot blasting machine through the feeding device, and are ejected into the casing under the action of the shot blasting machine. The spring is fed into the feeding pipe of the high casing under the action of the feeding device, slides down under the action of gravity, and is inserted into the wheel frame. Driven by the wheel frame, it rotates circumferentially, switches the angle to contact the projectiles thrown by the shot blasting machine, and performs surface strengthening treatment. After reaching the position of the discharge pipe, it slides down again under the action of gravity and then into the low casing. After the spring is reversed, the surface is treated again, and finally discharged from the discharge pipe of the low casing, and the projectiles are discharged from the discharge pipe.
