Description

Technical Field

[0001] The invention relates to the field of shot blasting machines, in particular to a safety spring-reinforced shot blasting machine. Background Art

[0002] Shot blasting machines are foundry equipment that utilizes high-speed projectiles to clean or strengthen the surface of castings. They can simultaneously desand, decore, and clean castings. They can also be used to remove burrs, diaphragms, and rust. They can also be used to remove contaminants from partially coated surfaces and create a surface profile that enhances coating adhesion, ultimately strengthening the workpiece.

[0003] In the shot blasting process of springs, due to the complex surface structure of the springs, the shot blasting process is often carried out by hanging or drum. This causes the processing process to be discontinuous and requires stopping the machine to remove the springs, resulting in a decrease in shot blasting efficiency. At the same time, the shot blasting effect on the spring surface is also uneven.

[0004] Therefore, a new type of spring reinforced shot blasting machine is needed to solve the above problems. Summary of the Invention

[0029] The following is a diagram of the present invention Figures 1-8 , clearly and completely describe the specific technical solutions of the present invention;

[0030] See also Figures 1-8 , Figure 1 Schematic diagram of the overall structure of an embodiment of the present invention; Figure 2 Schematic diagram of the internal structure of the casing of the present invention; Figure 3 This is a schematic diagram of the wheel frame structure of the present invention; Figure 4 For the present invention Figure 3 A magnified schematic diagram of the structure at A; Figure 5 This is a schematic structural diagram of the feed pipe of the present invention; Figure 6 This is a schematic diagram of the hanging needle structure of the present invention; Figure 7 For the present invention Figure 6 A magnified schematic diagram of the structure at B; Figure 8 It is a schematic diagram of the side panel structure of the present invention.

[0031] The present embodiment provides a safe spring-reinforced shot blasting machine, comprising a base frame, a housing with a double disc fixed on the base frame, a shot blaster driven by a drive motor A in the circumference of the housing for blasting shots into the housing, a spike-wheel-shaped wheel frame driven by a drive motor B in the housing, a spring feed pipe and a discharge pipe are symmetrically arranged on both sides of the housing obliquely and centrally, the feed pipe and the discharge pipe are both aligned with the needle-shaped structure on the circumference of the wheel frame, the two housings are arranged at a high and low position, the discharge pipe of the high housing is connected to the feed pipe of the low housing, and a shot discharge pipe is provided at the bottom of each housing;

[0032] 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, it also realizes the assembly line of spring shot blasting without stopping the machine for workpiece replacement, which greatly improves the processing efficiency.

[0033] Among them, the shot blasting machine is arranged between the feed pipe and the discharge pipe along the circumference of the casing and the direction of rotation of the wheel frame, so as to achieve the maximum change in the contact angle with the projectile while being as close as possible to the projectile throwing position, thereby improving the uniformity of shot blasting.

[0034] 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.

[0035] Among them, 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 action position being too narrow.

[0036] Specifically, the discharge pipe is provided with a sloped guide plate connected to the horizontal quarter point position of the wheel disc. The two ends of the guide plate correspond to the inner diameter of the wheel disc and the outer diameter range of the wheel frame respectively, 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.

[0037] 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.

[0038] The wheel frame includes a drive frame and a hanging needle. The drive frame is a disc structure that is rotated in the center of the housing and is connected to the drive motor B. The circumference of the drive frame is vertically provided with a hanging needle that rotates along its own circumference.

[0039] 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, changing the impact angle of the spring by the projectile in two dimensions, and achieving a uniform shot blasting effect.

[0040] Specifically, the hanging needle includes a driving shaft and a driving platform. The driving shaft is rotatably connected to the driving frame. The bottom end of the part protruding from the driving frame is provided with an enlarged driving platform. The driving platform is a frustum structure. The bottom of the spring is guided, limited and fixed by the conical driving platform to avoid excessive shaking during the processing process.

[0041] Furthermore, a protruding circumferential step structure is provided on the top conical surface of the driving platform;

[0042] 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.

[0043] Furthermore, the portion of the circumference of the drive shaft that extends into the drive frame has a gear ring structure, which engages and transmits with the drive gear ring protruding from the inner wall of the casing. The drive shaft moves relative to the gear ring as the drive frame rotates, thereby achieving synchronous driving of all hanging needles.

[0044] When implementing the technical solution recorded in this embodiment, after the shot blasting machine is started, the projectile is transported into the shot blasting wheel through the feeding device, and is ejected into the casing under the action of the shot blasting wheel, and the spring is fed into the feed 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 with the projectile thrown by the shot blasting wheel, 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 treatment is performed again, and finally it is discharged from the discharge pipe of the low casing, and the projectile is discharged from the discharge pipe.
