For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The specific embodiments are as follows:

[0024] Embodiment 1, as Figure 1-3 As shown, a pressing device for producing grinding wheels comprises a lathe body 1, a bracket 2, a lower mold support 3, a lower mold 4 and an upper mold 5. The lathe body 1 is fixedly connected with a gate arch-shaped bracket 2, and the upper mold 5 is adjustably connected to the bracket 2, and the upper mold 5 can move up and down relative to the bracket 2. The lower mold support 3 is fixed to the top of the lathe body 1, and is used to connect and support the lower mold 4.

[0025] A plurality of lower molds 4 are provided, and the inner diameters of the plurality of lower molds 4 are different so as to be used for producing grinding wheels of different sizes. The lower mold 4 is of a through-type, and a connecting groove 42 matching the lower mold support 3 is provided at its lower end. The inner diameter of the connecting groove 42 is larger than the inner diameter of the mold forming part of the lower mold 4, so that the lower mold 4 is sleeved on the lower mold support 3, and the top surface of the lower mold support 3 forms the bottom surface of the lower mold 4, so that the lower mold 4 constitutes a groove body space. A plurality of connecting ears 41 are provided at the circumferential bottom of the lower mold 4, and a clamping assembly 8 cooperating with the connecting ears 41 is provided on the top surface of the lathe body 1. The clamping assembly 8 can reciprocate along the radial direction of the lower mold support 3, so as to clamp and release the connecting ears 41, complete the detachable connection between the lower mold 4 and the lower mold support 3, and facilitate the replacement of the lower mold 4.

[0026] When using the pressing device for producing grinding wheels in this embodiment, a lower mold 4 of appropriate size is selected to be connected to the lower mold support 3, and the connection ear 41 is pressed by the pressing assembly 8 to realize the connection of the lower mold 4. The prepared abrasive and adhesive are placed in the lower mold 4, and the upper mold 5 is driven to move downward, and the upper mold 5 and the lower mold 4 are squeezed to form the grinding wheel. The lower mold 4 is detachably connected to the lower mold support 3, and multiple lower molds 4 with different inner diameters are provided, so that the lower mold 4 of appropriate size can be replaced according to production needs, thereby expanding the scope of application and meeting the needs of users.

[0027] Furthermore, the lower mold support 3 is in the shape of a truncated cone, which matches the conical shape of the connecting groove 42. In this way, when the lower mold 4 is sleeved and connected to the lower mold support 3, the coaxiality of the two can be ensured, thereby improving the accuracy of the grinding wheel production.

[0028] Furthermore, the clamping assembly 8 includes a bending clamping member 81, a screw 82 and a support block 83. The support block 83 is fixed to the top surface of the lathe body 1, the screw 82 passes through the support block 83 horizontally and is threadedly connected, the end of the screw 82 is rotatably connected to the bending clamping member 81, and the screw 82 is rotated to drive the bending clamping member 81 to move along the radial direction of the lower mold support 3, so as to complete the clamping and loosening of the bending clamping member 81 on the connecting ear 41. The clamping assembly 8 has a simple structure and is easy to operate.

[0029] In this embodiment, the screw rod 82 and the bending and pressing member 81 are connected via a bearing so that they can rotate relative to each other.

[0030] Furthermore, the pressing surface of the bent pressing member 81 for contacting the connecting ear 41 is arranged to be inclined so as to ensure the pressing of the connecting ear 41 .

[0031] Furthermore, an adjustment groove is provided at the end of the screw rod 82 away from the bending and pressing member 81 so as to adjust the screw rod 82 by means of a tool.

[0032] Furthermore, a column 31 is provided at the center of the top surface of the lower mold support 3, and an avoidance hole 51 is provided on the upper mold 5. The avoidance hole 51 cooperates with the column 31 to facilitate compression to form the grinding wheel.

[0033] Furthermore, the column 31 and the lower mold support 3 are connected by threads, which facilitates the disassembly and replacement of the column 31 and improves the flexibility of use.

[0034] Furthermore, the upper mold 5 and the bracket 2 are connected by a telescopic driving member 7 and a gate-type connecting frame 6. The telescopic driving member 7 is connected to the top of the bracket 2, and the lower end of the telescopic driving member 7 is threadedly connected to the gate-type connecting frame 6. The lower end of the gate-type connecting frame 6 is fixedly connected to the upper mold 5, so that the upper mold 5 of different sizes can be replaced as needed. In this way, it is not only convenient to replace the upper mold 5, but also space can be reserved for the avoidance hole 51 through the gate-type connecting frame 6 to ensure the normal pressing of the grinding wheel.

[0035] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method.
