Internal welded radiator header tube hole punched device and process thereof

Abstract

The invention discloses an internal-welding radiator header pipe punching device and a technique method thereof, comprising a punch, a control cabinet and a material feeding device. The material feeding device comprises a material supporting frame, a screw rod and a stepping motor driving the material supporting frame to move; one end of screw rod is fixedly supported on the workbench of the punch and the other end is transmitted and connected with the stepping motor which is electrically connected with the control cabinet; the workbench of the punch is provided with a punching die; the material supporting frame and the punching die are arranged in the same horizontal; a raw material pipe is arranged on the material supporting frame and the lower die of the punching die for positioning; a motor control switch on the control cabinet is pressed down to start the stepping motor which then drives the material supporting frame to transmit the raw material pipe to the processing position for punching; when the upper hole punching is implemented, the punching of holes at two sides is implemented at the same time. The invention has the advantages of advanced technique, high automation and high punch positioning precision, greatly improving production efficiency, reducing labor cost and having extremely good practical value.

Description

technical field [0001] The invention relates to production equipment and a process method for steel column radiators, in particular to an internally welded radiator header pipe punching device and a process method. Background technique [0002] In recent years, steel column radiators have developed very rapidly due to their low price, excellent thermal performance, high pressure resistance and good manufacturability. The traditional manufacturing method is to first Round tubes, square tubes or D-shaped tubes are drilled on a drilling machine, deburred, and then formed in pairs. The punching of the internal welded column radiator is also completed in three stages on three planes through three processes. The disadvantages of the method are that the positioning accuracy is poor, there are many molds and equipment used, the utilization rate of the equipment is low, the labor intensity of the workers is very high, and the operators are prone to safety accidents during operation, ...

[0002] In recent years, steel column radiators have developed very rapidly due to their low price, excellent thermal performance, high pressure resistance and good manufacturability. The traditional manufacturing method is to first Round tubes, square tubes or D-shaped tubes are drilled on a drilling machine, deburred, and then formed in pairs. The punching of the internal welded column radiator is also completed in three stages on three planes through three processes. The disadvantages of the method are that the positioning accuracy is poor, there are many molds and equipment used, the utilization rate of the equipment is low, the labor intensity of the workers is very high, and the operators are prone to safety accidents during operation, and the product quality is also difficult to guarantee. And the high cost of craftsmanship leads to an increase in the cost of the product. In today's fierce competition in the radiator market, if the cost is high, the sales price will also be high, which will reduce the competitive weight of the company's products.
