Embodiment 1

[0030] A manufacturing method of a baseball bat involved in Embodiment 1 of the present invention mainly includes the following steps:

[0031] Step 1, round the square material

[0032] Such as figure 2 As shown, the square raw material is processed into a cylindrical blank by using a back knife lathe;

[0033] Step 2, profiling

[0034] Such as image 3 As shown, the cylindrical body is profiled using a profiling lathe, and the profiling body of the large end part and the small end part are formed at both ends, as shown in figure 1 As shown, the big end part 4 is close to one end of the hitting part 3, and the small end part 1 is close to one end of the holding part 2;

[0035] Step 3, cut off the big end

[0036] Before the sanding process, cut off the large end;

[0037] Step 4, sanding

[0038] Such as Figure 4 As shown, fix the profiling blank after cutting off the big end part, and carry out sanding.

[0039] Through the processing of the above four steps, th...

Embodiment 2

[0041] A method for making a baseball bat involved in Embodiment 2 of the present invention, on the basis of the method for making a baseball bat mentioned in Embodiment 1, in step 4, as Figure 4 As shown, when the profiled blank is fixed, the end near the small end portion 1 of the profiled blank is fixed by the thimble of the sanding machine, and the end near the large end portion 2 of the profiled blank is fixed by the sleeve of the sanding machine. The barrel is fixed.

[0042] The profiling body is fixed by clamping at both ends, and the entire outer circumference of the profiling body can be sanded by rotating the profiling body during sanding, which improves the processing efficiency.

[0043] In addition, in step 4, after fixing the profiling body, push the thimble of the sanding machine so that the thimble is in direct alignment with the center point of the end close to the small end part 1, tighten the thimble, remove the sleeve, Sand it.

[0044] By aligning the ...

Embodiment 3

[0046] A kind of manufacturing method of baseball bat involved in embodiment 3 of the present invention, on the basis of the manufacturing method of baseball bat mentioned in embodiment 1, change the thimble of back knife lathe, profiling bed and sanding machine Among them, the size of the thimble of the copying bed is 1mm to 1.5mm longer than that of the back knife lathe, and the size of the thimble of the sanding machine is 1mm to 1.5mm longer than the size of the thimble of the copying bed.

[0047] In embodiment 3, the size of the thimble of each part is adjusted. By lengthening the size of the thimble, the baseball bat can be more firmly clamped on the device, thus, when the device rotates, the baseball bat can be kept from shaking, thereby improving the roundness of the processed baseball bat.

[0048] In addition, in the above-mentioned embodiments, a steel scale can also be installed on the tool holder of the equipment corresponding to the hitting position. The length...

Abstract

The invention provides a manufacture method of a baseball bat. The manufacture method mainly includes the following steps that firstly, lumber is turned to be round, and a square raw material is machined into a cylindrical green body through a back knife lathe; secondly, copying is conducted, wherein copying is conducted on the cylindrical green body through a copying lathe, a copying green body with a large tip portion and a small tip portion formed at the two ends correspondingly is obtained, the large tip portion is close to one end of a ball hitting position, and the small tip portion is close to one end of a handheld position; thirdly, the large tip portion is cut off, wherein the large tip portion is cut off before the sanding procedure is conducted; and fourthly, sanding is conducted, the copying green body with the large tip portion cut off is fixed, and sanding is conducted. By means of the manufacture method of the baseball bat, the large tip portion is cut off before sanding, and therefore the weight of the baseball bat can be controlled during sanding, and the one-time finished product rate of products can be increased.

Description

technical field [0001] The invention relates to the technical field of sporting goods production, in particular to a production method of a baseball bat. Background technique [0002] In the existing manufacturing process of baseball bats, the usual processing flow is: use a back knife lathe to carry out square turning processing on square raw materials, and then use a profiling lathe to carry out profiling processing on the rounded billets, and then use The grinding machine sands the profiled blank, then paints it, and finally cuts off the excess to process the finished baseball bat. [0003] In the existing manufacturing process of baseball bats, the products after spraying paint are usually repaired because of the weight problem. Light-weight baseball bats are remade into small models or scrapped directly. Heavy-weight baseball bats need to be re-sanded and painted. At the same time, in the existing baseball bat manufacturing method, in the process of sanding, because t...
