Description

Technical Field

[0001] The present application relates to the field of excavator component production, and specifically to a bucket plate cutting device. Background Art

[0002] An excavator is composed of multiple parts, including a motor, tracks, a transmission system, a cylinder bucket, etc. Each bucket of the excavator includes two side plates. When producing the bucket, the steel plate needs to be cut into side plates. Currently, flame cutting or plasma cutting is usually used in the cutting step.

[0003] The existing cutting machine bed can only play the basic role of supporting the cutting machine. During the cutting process, a large number of sparks will be generated. The high temperature of the sparks and the high temperature of the waste after cutting will continue for a long time and will affect the equipment production or production safety.

[0004] Therefore, it is necessary to provide a bucket plate cutting device to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a bucket plate cutting device to solve the problem of poor heat dissipation of the cutting machine base.

[0007] The technical solution adopted by the present application to solve the technical problem is: a bucket plate cutting device, comprising a body and a bed frame; the top of the body and the bed frame are detachable structures, and the bed frame is used to place the plate;

[0008] The bed frame includes an upper body and a lower body; the bottom of the lower body is clamped with the body, and the bottom of the upper body is clamped with the lower body, and fixed by bolts; the interior of the upper body and the interior of the lower body form a hollow cavity; thus, the plate is placed on the top of the upper body for cutting, and after the upper body is heated, the hollow cavity plays a heat-insulating role, so that the lower body is less heated, the thermal expansion change of the lower body is small, and the deformation probability of the connection between the lower body and the body is reduced, thereby extending the service life of the connection between the lower body and the body.

[0009] Furthermore, the bed frame also includes multiple air inlet openings and multiple exhaust pipe openings; one end of the multiple air inlet openings passes through one side of the upper end body and the lower end body, and the multiple air inlet openings are evenly arranged; one end of the multiple exhaust pipe openings passes through the other side of the upper end body and the lower end body, and the multiple exhaust pipe openings are evenly arranged; the exhaust pipe openings and the air inlet openings are symmetrically arranged, and the inner sides of the exhaust pipe openings and the air inlet openings are connected to the hollow cavity, and the end of the air inlet opening away from the upper end body is connected to an air pump through a pipeline, and the end of the exhaust pipe opening away from the upper end body is connected to the external space through a pipeline; thereby, the air pump passes the cooling air into the hollow cavity through the air inlet opening and discharges it from the exhaust pipe opening, thereby achieving cooling of the hollow cavity and the upper end body, reducing the degree of thermal expansion of the upper end body, and indirectly extending the service life of the upper end body.

[0010] Furthermore, the end surface of the upper end body is evenly provided with recesses, and the end surface of the lower end body is evenly provided with convex cylinders, the recesses correspond to the convex cylinders one by one, and are relatively arranged, and the internal space of the recesses is connected with the internal space of the convex cylinders; thus, the outer top space of the upper end body and the outer bottom space of the lower end body are connected through the recesses and the convex cylinders, thereby providing a flow space for the hot air flow at the upper end body, and at the same time, the chips generated by the plate processing can be discharged in time from the channel formed by the recesses and the convex cylinders, avoiding excessive accumulation of chips on the upper end body and affecting the effect of plate processing.

[0011] Furthermore, one end of the recess is clearance-fitted with the inner wall of the convex cylinder; the recess is trumpet-shaped, the inner wall of the convex cylinder is outwardly expanded, and an annular channel is formed between the recess and the convex cylinder; one end of the annular channel is connected to the hollow cavity, and the other end of the annular channel is connected to the inside of the convex cylinder; thus, part of the airflow flowing in the hollow cavity enters the convex cylinder from the annular channel, and is then discharged from the bottom of the lower end body; at this time, the recess is in a low-pressure state, and the airflow at the top of the upper end body is quickly discharged from the recess, thereby achieving rapid heat dissipation at the upper end body; at the same time, it also has a certain degree of adsorption capacity for the plate, indirectly ensuring the stability of the plate.

[0012] Furthermore, two movable guide rails are fixedly installed on the top of the machine body, and the bed frame is located between the two movable guide rails; the sides of the movable guide rails are slidably connected with movable seats, a cross beam is fixedly installed between the two movable seats, and a transverse driving seat is installed on one side of the cross beam through a sliding connection; a vertical driving seat is fixedly installed on the side of the transverse driving seat away from the cross beam, and a processing part is fixedly installed on one end of the vertical driving seat; thus, the movable seat moves on the movable guide rail to realize longitudinal displacement of the processing part, the transverse driving seat moves on the cross beam to realize transverse displacement of the processing part, and the vertical driving seat controls the height displacement of the processing part, thereby realizing precise processing of the plate by the processing part.

[0013] The beneficial effects of the present application are: a bucket plate cutting device provided by the present application is provided with an upper end body, a lower end body, and a hollow cavity. The plate is placed on the top of the upper end body for cutting. After the upper end body is heated, the hollow cavity plays a heat insulating role, so that the lower end body is less heated, the thermal expansion change of the lower end body is small, and the deformation probability of the connection between the lower end body and the machine body is reduced, thereby extending the service life of the connection between the lower end body and the machine body.

[0026] like Figure 1-Figure 5 As shown, the present application provides a bucket plate cutting device, referring to Figure 1 , including a body 11 and a bed frame 13; the top of the body 11 and the bed frame 13 are detachable structures, and the bed frame 13 is used to place the plate;

[0027] Reference Figure 2 , Figure 3 The bed frame 13 includes an upper body 131 and a lower body 132; the bottom of the lower body 132 is clamped with the body 11, and the bottom of the upper body 131 is clamped with the lower body 132, and fixed by bolts; the interior of the upper body 131 and the interior of the lower body 132 form a hollow cavity 133; thus, the plate is placed on the top of the upper body 131 for cutting, and after the upper body 131 is heated, the hollow cavity 133 plays a heat insulation role, so that the lower body 132 is less heated, the thermal expansion change of the lower body 132 is small, and the deformation probability of the connection between the lower body 132 and the body 11 is reduced, thereby extending the service life of the connection between the lower body 132 and the body 11.
