Description

Technical Field

[0001] This utility model relates to the field of brazed diamond drill bits, and in particular to a cooling and demolding device for brazed diamond drill bits. Background Technology

[0002] The cooling and demolding process of brazed diamond drill bits involves a dedicated cooling and demolding device. This device includes a fixed upper cooling plate, a lower cooling plate that can move along a guide rail, an electric push rod, and a top rod connected to the electric push rod via a connector. A spring is installed on the top rod. The working process of the mechanism is divided into two steps: cooling and demolding. The design of this device aims to effectively shorten the cooling time after brazing and heat preservation of multi-layer brazed diamond drill bits and solve problems such as demolding difficulties, thereby improving production efficiency and reducing labor intensity.

[0003] Cooling is a critical step in the production of brazed diamond drill bits because it directly affects the quality and performance of the drill bit. Traditional cooling methods, such as slow cooling in a natural environment, may cause thermal stress in the drill bit and mold during the cooling process, leading to deformation or damage. Existing cooling and demolding devices are also relatively simple and lack the ability to clamp and limit the workpiece. The workpiece is placed directly on the lower cooling plate, which can easily cause displacement of the workpiece during lifting and demolding operations. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a cooling and demolding device for brazed diamond drill bits to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1As shown in Figure 5, this embodiment provides a cooling and demolding device for brazed diamond drill bits, including a device body 1. The device body 1 includes a base 2, a clamping assembly 5, and a cooling assembly 6. The base 2 is provided with four sets of positioning posts 21, and an upper cooling plate 3 is fixed to the top of the positioning posts 21. A lower cooling plate 4 is provided at the lower end of the upper cooling plate 3, and the lower cooling plate 4 is slidably sleeved on the positioning posts 21. The clamping assembly 5 is provided on the surface of the lower cooling plate 4. The cooling assembly 6 is provided on one side of the base 2 and connected to the upper cooling plate 3 and the lower cooling plate 4. A lower cylinder 7 is provided at the center of the base 2, and a ejector pin 8 and a spring 9 are connected to the top of the lower cylinder 7. The spring 9 is movably sleeved on the outside of the ejector pin 8 and an upper gasket 91 is connected to the upper end. The upper gasket 91 is attached to the lower end of the lower cooling plate 4.

[0025] Preferably, the clamping assembly 5 includes a hinge seat 51, a bidirectional screw 52 is rotatably mounted on one side of the hinge seat 51, two sets of clamping plates 54 are screwed onto the bidirectional screw 52 in opposite directions, a guide rod 55 is provided on the hinge seat 51 on the symmetrical side of the bidirectional screw 52, ​​a guide hole 56 is provided on one side of the clamping plate 54, the guide rod 55 moves through the guide hole 56, the hinge seat 51 is fixed on both sides of the upper end of the lower cooling plate 4, two sets of knobs 53 are provided on the outer end of the bidirectional screw 52, ​​and a protective pad 57 is provided on the inner side of the clamping plate 54;

[0026] The rotation of the bidirectional screw 52 is controlled by the knob 53. The bidirectional screw 52 drives the two clamping plates 54 on both sides to move inward. The clamping plates 54 move along the guide rod 55, thereby realizing the clamping and limiting operation of the workpiece. This facilitates the maintenance of the stability of the workpiece during cooling and demolding, avoids displacement of the workpiece under force, and improves the stability of the device.

[0027] Preferably, the cooling assembly 6 includes a water tank 61. A water pump 62 is provided at the upper end of the water tank 61 and a water inlet pipe 63 is connected to the water pump 62. A connector 64 is provided at the front end of the water inlet pipe 63 and a circulation pipe 65 is connected to the outside of the connector 64. The other end of the circulation pipe 65 is connected to an outlet pipe 66. The lower end of the outlet pipe 66 leads into the water tank 61. Connectors 64 are provided at both ends of the circulation pipe 65. Two sets of circulation pipes 65 are provided. The two sets of circulation pipes 65 are arranged in an S-shaped structure and are respectively coiled inside the upper cooling plate 3 and the lower cooling plate 4. A water inlet 67 is provided at the upper end of one side of the water tank 61 and a drain outlet 68 is provided at the lower end of one side of the water tank 61.

[0028] Water is drawn from the water tank 61 by the water pump 62, sent to the circulation pipe 65 through the water inlet pipe 63 for circulation cooling, and returned to the water tank 61 through the water outlet pipe 66. This enables the circulation and guidance of cooling water, which facilitates water cooling of the workpiece and maintains the cooling effect of the cooling water. The S-shaped circulation pipe 65 can increase the contact area and time between the cooling water and the cooling plate, further improving the cooling effect on the workpiece.

[0029] The working principle and process of this utility model are as follows: During use, the workpiece can be placed on the lower cooling plate 4. The double-ended screw 52 is rotated by the knob 53, which drives the two side clamping plates 54 to move inwards. The clamping plates 54 move along the guide rod 55 and are attached to both sides of the workpiece by the protective pads 57, thus achieving clamping and limiting of the workpiece and maintaining its stability. At this time, the ejector pin 8 can be driven to rise by the lower cylinder 7. The upper pad 91 contacts the bottom surface of the lower cooling plate 4 and compresses the spring 9, causing it to contract. The lower cylinder 7 continues to extend and retract, causing the lower cooling plate 4 to rise along the positioning post 21. Stop when the upper surface of the workpiece is in contact with the lower surface of the upper cooling plate 3. At this time, the water pump 62 draws cooling water from the water tank 61 and sends it to the circulation pipe 65 through the water inlet pipe 63 for circulation, thereby cooling the workpiece. Finally, the water flows back to the water tank 61 through the water outlet pipe 66. At this time, the lower cylinder 7 is raised and the lower cooling plate 4 cannot move. At this time, the spring 9 will be compressed again, and the ejector pin 8 will pass through the center hole of the lower cooling plate 4 and push out the brazed diamond drill bit, so that the brazed diamond drill bit is detached from the workpiece. After the drill bit is pushed out, the equipment can be reset.
