Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing, and relates to a graphite cutting processing impact protection structure. Background Art

[0002] Graphite is a common non-metallic material, black in color, with high and low temperature resistance, good electrical and thermal conductivity, good lubricity and stable chemical properties. Since graphite is a brittle material with a heterogeneous structure, graphite cutting is mainly achieved by generating discontinuous chip particles or powder through the brittle fracture of graphite materials.

[0003] Since graphite cutting is usually carried out on customized molds, and the pretreatment of graphite usually adopts the inlay method to complete the inlay of graphite and mold, during the inlay and subsequent milling processing, the knocking inlay method and the impact of the subsequent tool will cause damage to the graphite to a certain extent, thereby increasing the loss rate of graphite and wasting processing resources.

DETAILED DESCRIPTION

[0019] See also Figure 1-3 , the embodiments of the utility model are further described;

[0020] A graphite cutting impact protection structure comprises a bolt head 1 and a bolt column 5, wherein the bolt column 5 is longitudinally butted and fixed to the bolt head 1, and an inner ring handle 6 is slidably fitted in the bolt head 1, and a buffer shaft 8 is provided in the inner ring handle 6 extending into the bolt column 5, a compression spring seat 12 is fixedly provided in the bolt column 5, and a vertical shaft rail 11 is slidably fitted between the compression spring seat 12 and the buffer shaft 8, and a spring coil is crimped and fitted at the outer end between the compression spring seat 12 and the buffer shaft 8;

[0021] A secondary handle 2 is provided on one side of the bolt pipe head 1, and a ring handle member 9 is hingedly provided between the secondary handle 2 and the inner ring handle 6. A veneer panel 3 is bolted and fixed on the secondary handle 2, and the veneer panel 3 is a calendered membrane panel with a smooth surface.

[0022] In this structure, the integrally formed bolt head 1 and bolt column 5 are used as the attachment end of the auxiliary handle 2 structure. The attachment method is as follows: Figure 3 As shown, the bolt head 1 is assembled in a plug-in manner according to the distribution of the positioning holes of the graphite mold, so as to facilitate the adaptation and fixation with the various corners of the veneer panel 3 by means of multi-point setting, wherein the connection between the veneer panel 3 and the bolt head 1 structure is arranged on the inner ring handle 6 structure, and the inner ring handle 6 performs axial compression and buffering activities between the bolt head 1 and the bolt column 5 through the buffer shaft 8 at the axial position of the bolt head 1, wherein the buffer shaft 8 is axially limited by the vertical shaft rail 11, and axial compression and buffering are performed in combination with the spring coil on the compression spring seat 12, so as to balance the axial expansion and contraction of the veneer panel 3 and the auxiliary handle 2 structure at the point position, thereby combining the contact between the veneer panel 3 structure and the graphite surface of the mold to provide impact protection for the graphite surface;

[0023] Taking into account the problem of excessive graphite loss in the existing processing process, the protection structure uses a bolt head 1 structure arranged at multiple points to cooperate with the veneer panel 3 for assembly and fixation, which improves the applicability of the structure while ensuring the reliability of the structure.

[0024] Preferably, the inner ring handle 6 is a semi-annular pipe fitting, and positioning slides 7 that movably cooperate with the inner wall of the bolt head 1 are fixed at both ends of the inner ring handle 6, and the inner wall of the bolt head 1 is engraved with a longitudinal groove that matches the positioning slide 7. The inner ring handle 6 adopts a semi-annular pipe fitting structure to adapt to the plug-in fixing method of the bolt head 1 and the mold, and on this basis, the axial position of the connection structure between the inner ring handle 6 and the bolt head 1 is ensured by matching the positioning slide 7 with the groove, thereby avoiding the influence of the axial structure deviation on the axial buffer.

[0025] Preferably, the outer end of the bolt column 5 is sleeved with a spring tube ring 4, such as Figure 1 , 3 As shown, the bolt tube column 5 is plugged and assembled with the mold positioning hole by plug-in assembly, wherein the spring tube ring 4 serves as a buffer structure for the entire bolt tube head 1 and the outside of the bolt tube column 5 to avoid impact damage to the mold positioning hole caused by stamping when the structure is combined with the mold.

[0026] Preferably, a handle head 13 is transversely provided between the buffer shaft 8 and the vertical shaft rail 11, and a groove longitudinally matching the handle head 13 is provided on the side of the buffer shaft 8. The handle head 13, based on the original axial connection structure between the buffer shaft 8 and the vertical shaft rail 11, utilizes the axial clamping between the groove and the handle head 13 to avoid radial deviation of the buffer shaft 8 and the vertical shaft rail 11 while adapting to the axial displacement, so as to ensure the stability of the axial structure.

[0027] Preferably, an angle steel column 10 is provided through the inner side of the connecting end of the auxiliary handle 2 and the veneer panel 3, and the angle steel column 10 forms a matching inclination angle relative to the side close to the veneer panel 3. The angle steel column 10 serves as an expansion structure of the bolted end of the auxiliary handle 2 and the veneer panel 3, and can fill the axial structure of the auxiliary handle 2 through the angle steel column 10 to reinforce the stability of the axial connection structure between the auxiliary handle 2 and the veneer panel 3.

[0028] On the basis of the above, the bolted end of the ring handle 9 and the angle steel column 10 are clamped and fixed. By clamping and fixing the ring handle 9 and the angle steel column 10, the axial structure of the angle steel column 10 is simultaneously used to reinforce the ring handle 9 to ensure the reliability of the connection structure between the auxiliary handle 2 and the bolt head 1.

[0029] The implementation method of the device is to insert the ends of the structural bolt head 1 and the bolt column 5 into the positioning holes according to the distribution of the positioning holes of the graphite mold, and then fix them to the corners of the veneer panel 3 by bolting. During the graphite inlay operation, the buffer shaft 8 at the axial position of the inner ring handle 6 and the bolt head 1 can be used to perform axial compression and buffering activities in the bolt head 1 and the bolt column 5, wherein the buffer shaft 8 is axially limited by the vertical shaft rail 11, and axial compression and buffering are performed in combination with the spring coil on the compression spring seat 12, so as to balance the axial expansion and contraction of the veneer panel 3 and the auxiliary handle 2 structure at the point position, thereby combining the contact between the veneer panel 3 structure and the graphite surface of the mold to provide impact protection for the graphite surface.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
